+1 Notes on the Free Translation Project
+***************************************
+
+Free software is going international!  The Free Translation Project is a
+way to get maintainers of free software, translators, and users all
+together, so that free software will gradually become able to speak many
+languages.  A few packages already provide translations for their
+messages.
+
+   If you found this 'ABOUT-NLS' file inside a distribution, you may
+assume that the distributed package does use GNU 'gettext' internally,
+itself available at your nearest GNU archive site.  But you do _not_
+need to install GNU 'gettext' prior to configuring, installing or using
+this package with messages translated.
+
+   Installers will find here some useful hints.  These notes also
+explain how users should proceed for getting the programs to use the
+available translations.  They tell how people wanting to contribute and
+work on translations can contact the appropriate team.
+
+1.1 INSTALL Matters
+===================
+
+Some packages are "localizable" when properly installed; the programs
+they contain can be made to speak your own native language.  Most such
+packages use GNU 'gettext'.  Other packages have their own ways to
+internationalization, predating GNU 'gettext'.
+
+   By default, this package will be installed to allow translation of
+messages.  It will automatically detect whether the system already
+provides the GNU 'gettext' functions.  Installers may use special
+options at configuration time for changing the default behaviour.  The
+command:
+
+     ./configure --disable-nls
+
+will _totally_ disable translation of messages.
+
+   When you already have GNU 'gettext' installed on your system and run
+configure without an option for your new package, 'configure' will
+probably detect the previously built and installed 'libintl' library and
+will decide to use it.  If not, you may have to to use the
+'--with-libintl-prefix' option to tell 'configure' where to look for it.
+
+   Internationalized packages usually have many 'po/LL.po' files, where
+LL gives an ISO 639 two-letter code identifying the language.  Unless
+translations have been forbidden at 'configure' time by using the
+'--disable-nls' switch, all available translations are installed
+together with the package.  However, the environment variable 'LINGUAS'
+may be set, prior to configuration, to limit the installed set.
+'LINGUAS' should then contain a space separated list of two-letter
+codes, stating which languages are allowed.
+
+1.2 Using This Package
+======================
+
+As a user, if your language has been installed for this package, you
+only have to set the 'LANG' environment variable to the appropriate
+'LL_CC' combination.  If you happen to have the 'LC_ALL' or some other
+'LC_xxx' environment variables set, you should unset them before setting
+'LANG', otherwise the setting of 'LANG' will not have the desired
+effect.  Here 'LL' is an ISO 639 two-letter language code, and 'CC' is
+an ISO 3166 two-letter country code.  For example, let's suppose that
+you speak German and live in Germany.  At the shell prompt, merely
+execute 'setenv LANG de_DE' (in 'csh'), 'export LANG; LANG=de_DE' (in
+'sh') or 'export LANG=de_DE' (in 'bash').  This can be done from your
+'.login' or '.profile' file, once and for all.
+
+   You might think that the country code specification is redundant.
+But in fact, some languages have dialects in different countries.  For
+example, 'de_AT' is used for Austria, and 'pt_BR' for Brazil.  The
+country code serves to distinguish the dialects.
+
+   The locale naming convention of 'LL_CC', with 'LL' denoting the
+language and 'CC' denoting the country, is the one use on systems based
+on GNU libc.  On other systems, some variations of this scheme are used,
+such as 'LL' or 'LL_CC.ENCODING'.  You can get the list of locales
+supported by your system for your language by running the command
+'locale -a | grep '^LL''.
+
+   Not all programs have translations for all languages.  By default, an
+English message is shown in place of a nonexistent translation.  If you
+understand other languages, you can set up a priority list of languages.
+This is done through a different environment variable, called
+'LANGUAGE'.  GNU 'gettext' gives preference to 'LANGUAGE' over 'LANG'
+for the purpose of message handling, but you still need to have 'LANG'
+set to the primary language; this is required by other parts of the
+system libraries.  For example, some Swedish users who would rather read
+translations in German than English for when Swedish is not available,
+set 'LANGUAGE' to 'sv:de' while leaving 'LANG' to 'sv_SE'.
+
+   Special advice for Norwegian users: The language code for Norwegian
+bokma*l changed from 'no' to 'nb' recently (in 2003).  During the
+transition period, while some message catalogs for this language are
+installed under 'nb' and some older ones under 'no', it's recommended
+for Norwegian users to set 'LANGUAGE' to 'nb:no' so that both newer and
+older translations are used.
+
+   In the 'LANGUAGE' environment variable, but not in the 'LANG'
+environment variable, 'LL_CC' combinations can be abbreviated as 'LL' to
+denote the language's main dialect.  For example, 'de' is equivalent to
+'de_DE' (German as spoken in Germany), and 'pt' to 'pt_PT' (Portuguese
+as spoken in Portugal) in this context.
+
+1.3 Translating Teams
+=====================
+
+For the Free Translation Project to be a success, we need interested
+people who like their own language and write it well, and who are also
+able to synergize with other translators speaking the same language.
+Each translation team has its own mailing list.  The up-to-date list of
+teams can be found at the Free Translation Project's homepage,
+'http://translationproject.org/', in the "Teams" area.
+
+   If you'd like to volunteer to _work_ at translating messages, you
+should become a member of the translating team for your own language.
+The subscribing address is _not_ the same as the list itself, it has
+'-request' appended.  For example, speakers of Swedish can send a
+message to 'sv-request@li.org', having this message body:
+
+     subscribe
+
+   Keep in mind that team members are expected to participate _actively_
+in translations, or at solving translational difficulties, rather than
+merely lurking around.  If your team does not exist yet and you want to
+start one, or if you are unsure about what to do or how to get started,
+please write to 'coordinator@translationproject.org' to reach the
+coordinator for all translator teams.
+
+   The English team is special.  It works at improving and uniformizing
+the terminology in use.  Proven linguistic skills are praised more than
+programming skills, here.
+
+1.4 Available Packages
+======================
+
+Languages are not equally supported in all packages.  The following
+matrix shows the current state of internationalization, as of Jun 2014.
+The matrix shows, in regard of each package, for which languages PO
+files have been submitted to translation coordination, with a
+translation percentage of at least 50%.

+   Some counters in the preceding matrix are higher than the number of
+visible blocks let us expect.  This is because a few extra PO files are
+used for implementing regional variants of languages, or language
+dialects.
+
+   For a PO file in the matrix above to be effective, the package to
+which it applies should also have been internationalized and distributed
+as such by its maintainer.  There might be an observable lag between the
+mere existence a PO file and its wide availability in a distribution.
+
+   If Jun 2014 seems to be old, you may fetch a more recent copy of this
+'ABOUT-NLS' file on most GNU archive sites.  The most up-to-date matrix
+with full percentage details can be found at
+'http://translationproject.org/extra/matrix.html'.
+
+1.5 Using 'gettext' in new packages
+===================================
+
+If you are writing a freely available program and want to
+internationalize it you are welcome to use GNU 'gettext' in your
+package.  Of course you have to respect the GNU Lesser General Public
+License which covers the use of the GNU 'gettext' library.  This means
+in particular that even non-free programs can use 'libintl' as a shared
+library, whereas only free software can use 'libintl' as a static
+library or use modified versions of 'libintl'.
+
+   Once the sources are changed appropriately and the setup can handle
+the use of 'gettext' the only thing missing are the translations.  The
+Free Translation Project is also available for packages which are not
+developed inside the GNU project.  Therefore the information given above
+applies also for every other Free Software Project.  Contact
+'coordinator@translationproject.org' to make the '.pot' files available
+to the translation teams.

+the previous version, bash-5.2-rc4.
+
+1. Changes to Bash
+
+2. Changes to Readline
+
+a. When replacing a history entry, make sure the existing entry has a non-NULL
+   timestamp before copying it; it may have been added by the application, not
+   the history library.
+
+3. New Features in Bash
+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.2-rc4, and
+the previous version, bash-5.2-rc3.
+
+1. Changes to Bash
+
+a. Changed how the compatibility mode enabling of extglob works in conjunction
+   with parsing conditional commands.
+
+b. Fixed a problem with aliases containing command substitutions.
+
+2. Changes to Readline
+

+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.2-rc3, and
+the previous version, bash-5.2-rc2.
+
+1. Changes to Bash
+
+a. Added a compatibility mode feature that causes the parser to parse command
+   substitutions as if extglob were enabled. If it is enabled before execution,
+   parse at execution will succeed. If not, the subsequent execution parse will
+   fail.
+
+b. Fixed an issue with handling a `return' executed in a trap action if the
+   trap is executed while running in a shell function.
+
+2. Changes to Readline
+
+3. New Features in Bash
+
+4. New Features in Readline
+
+a. Readline now checks for changes to locale settings (LC_ALL/LC_CTYPE/LANG)
+   each time it is called, and modifies the appropriate locale-specific display
+   and key binding variables when the locale changes.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.2-rc2, and
+the previous version, bash-5.2-rc1.
+
+1. Changes to Bash
+
+a. Fixed a bug that could disable history saving after a compound array
+   assignment in an interactive shell.
+
+b. Fixed a bug that could cause incorrect error messages when running a DEBUG
+   trap during a conditional or arithmetic command.
+
+c. Fixed a bug that caused test to print an error message when given ! ! arg
+   as arguments.
+
+d. Fixed a bug that resulted in incorrect error messages when completing a
+   backquoted command substitution.
+
+e. Changed command substitution parsing to reproduce the original text more
+   closely when reconsituting the command string from the parsed command.
+
+f. Fixed a bug that could cause an EXIT trap to use the wrong variable context
+   when the errexit option is set.
+
+g. Fixed a bug that could cause the parser to incorrectly delimit a token when
+   an alias expansion ended with a multibyte character.
+
+2. Changes to Readline
+
+3. New Features in Bash
+
+a. Since there is no `declare -' equivalent of `local -', make sure to use
+   `local -' in the output of `local -p'.
+
+b. Null anchored matches in pattern substitution now process `&' in the
+   replacement string, like sed.
+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.2-rc1, and
+the previous version, bash-5.2-beta.
+
+1. Changes to Bash
+
+a. Changes to `wait -p' and how it sets the variable name in the presence of
+   valid and invalid PID arguments.
+
+b. Fixed a bug that caused compgen to dump core if the completion engine was
+   not initialized.
+
+c. Fixed a memory leak in the variable name programmable completion code.
+
+d. Here-documents and here-strings use tempfiles if the shell compatibility
+   level is 50 or lower.
+
+e. Non-interactive shells exit on a syntax error encountered while parsing a
+   command substitution.
+
+f. Fixed a bug with inherited parser state while parsing a command substitution.
+
+g. Fixed a bug that caused the shell not to check for terminating signals
+   after executing the command_string supplied with `-c' and before executing
+   the exit trap.
+
+h. Changes to avoid a make race condition while generating builtins.c.
+
+i. Make it explicit that BASH_REMATCH is always a global variable, and that
+   local copies are (currently) ignored.
+
+j. Fixed a bug that caused an ambiguous redirection (>&word) to be printed
+   incorrectly (>&word) if no file descriptor was supplied.
+
+2. Changes to Readline
+
+a. Fixed a bug that caused rl_eof_found to be set prematurely while reading a
+   multi-character key sequence in callback mode.
+
+3. New Features in Bash
+
+a. In posix mode, the `printf' builtin checks for the `L' length modifier and
+   uses long double for floating point conversion specifiers if it's present,
+   double otherwise.
+
+b. The `globbing' completion code now takes the `globstar' option into account.
+
+c. `suspend -f' now forces the shell to suspend even if job control is not
+   currently enabled.
+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.2-beta, and
+the previous version, bash-5.2-alpha.
+
+1. Changes to Bash
+
+a. Fixed a problem with command-oriented history and multi-line commands that
+   caused embedded blank lines to be run together.
+
+b. Changed the way `&' is quoted when performing pattern substitution and
+   `patsub_replacement' is enabled.
+
+c. Fixed some integer overflows when expanding strings or reading the output
+   of command substitution larger than 2GB.
+
+d. `wait -p' without the `-n' option now does something useful if there are no
+   jobs.
+
+e. Fixed an issue with read timeouts in posix mode.
+
+f. Changed here-document processing to process $'...' and $"..." only when they
+   appear in the WORD portion of ${PARAM OP WORD} in the here-document body
+   and the body is being expanded.
+
+g. Changed alias expansion in command substitution to be posix-conformant
+   (performed while initially parsing the command substitution) when in posix
+   mode.
+
+h. Bash optimizes away more forks in subshells.
+
+i. Here-document construction now performs quote removal on the here-document
+   delimiter only if it's marked as quoted, which prevents quote characters in
+   command substitutions from being removed.
+
+j. Prompt string expansion now gives invisible characters in the expansion of
+   the \w, \W, and \s escape sequences a visible representation to avoid
+   problems with redisplay.
+
+k. Fixed a problem with SIGINT during the execution of a command bound with
+   `bind -x' affecting the saved terminal settings.
+
+l. Fixed an inconsistency with how $@ expands in a construct like ${@:+set}
+   or ${array[@]:+set} in the presence of null positional parameters or
+   array elements.
+
+2. Changes to Readline
+
+a. Prevent some display problems when running a command as the result of a
+   trap or one bound using `bind -x' and the command generates output.
+
+b. Fixed an issue with multi-line prompt strings that have one or more
+   invisible characters at the end of a physical line.
+
+c. Fixed an issue that caused a history line's undo list to be cleared when
+   it should not have been.
+
+3. New Features in Bash
+
+a. There is a new bindable readline command name: `vi-edit-and-execute-command'.
+
+4. New Features in Readline
+
+a. Two new bindable string variables: active-region-start-color and
+   active-region-end-color. The first sets the color used to display the
+   active region; the second turns it off. If set, these are used in place
+   of terminal standout mode.
+
+b. New readline state (RL_STATE_EOF) and application-visible variable
+   (rl_eof_found) to allow applications to detect when readline reads EOF
+   before calling the deprep-terminal hook.
+
+c. There is a new configuration option: --with-shared-termcap-library, which
+   forces linking the shared readline library with the shared termcap (or
+   curses/ncurses/termlib) library so applications don't have to do it.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.2-alpha, and
+the previous version, bash-5.1-release.
+
+1. Changes to Bash
+
+a. Fixed a bug that assigned a value to the variable name supplied as an
+   argument to `wait -p' when there were no jobs.
+
+b. Fixed a bug that resulted in performing incorrect word expansion on the
+   key/value pairs in a compound array assignment.
+
+c. Fixed a bug that could put the child forked to run a command substitution
+   into the wrong process group.
+
+d. Fixed a problem that could cause the lastpipe option to work incorrectly if
+   file descriptor 0 was closed.
+
+e. Bash tries to suppress traps if a forked child receives a trapped signal
+   before it has a chance to reset its signal handlers.
+
+f. Fixed several memory leaks in compound array assignments.
+
+g. Fixed a problem with performing an assignment with `+=' to an array element
+   that was the value of a nameref.
+
+h. Fixed a bug that could cause a nameref containing an array reference using
+   `@' or `*' not to expand to multiple words.
+
+i. Fixed a bug where extended glob functions could match `.' or `..' when it
+   wasn't explicitly specified, even if dotglob was set.
+
+j. Fixed a bug that caused non-interactive posix-mode shells not to exit on a
+   variable assignment error while assigning into the temporary environment.
+
+k. Fixed a bug that caused parsing errors if an alias contained a compound
+   array assignment.
+
+l. Fixed a couple of instances where bash checked syntax too aggressively when
+   trying to determine how to add a partial command to command-oriented
+   history.
+
+m. Fixed a parser problem that caused it not to allow reserved words to follow
+   the `((' and `[[' commands.
+
+n. Fixed a bad offset calculation when using negative offsets to `history -d'.
+
+o. Fixed an off-by-one error that caused a read past the end of a buffer when
+   reading a multibyte character from the output of a command substitution.
+
+p. Fixed a problem with a failed `exec' command not setting $? to the right
+   value for an exit trap.
+
+q. Fixed a problem that caused bash not to unlink FIFOs created as part of
+   expanding redirections for an external command.
+
+r. Fixed a bug that could cause aliases not to be expanded in case statements.
+
+s. Fixed a bug that could cause word completion to attempt programmable
+   completion for the target of a redirection, instead of filename completion.
+
+t. Fixed a bug that could result in errors after rebinding a key sequence with
+   `bind -x' multiple times.
+
+u. Fixed a problem that could result in not quoting the result when performing
+   command name completion with a glob pattern in the command name.
+
+v. `mapfile' now uses fully-buffered reads in more cases, which should improve
+   bulk read performance.
+
+w. Fixed a bug that caused `wait -n' to not reset its internal state when
+   interrupted by a signal, resulting in subsequent calls failing.
+
+x. Fixed a bug with parsing numeric arguments to readline key sequences
+   installed with `bind -x'.
+
+y. Bash suppresses forking in several additional cases, including most uses
+   of $(<file).
+
+z. If there are multiple `!' tokens in a [[ command, toggle the invert state
+   instead of setting it unconditionally.
+
+aa. Fixed a bug where running `fc' on an empty history list would cause the
+    shell to crash.
+
+bb. Word completion now checks whether or not a quote character closes a
+    quoted string begun on a previous line, so readline doesn't interpret the
+    quote as starting a new quoted string.
+
+cc. Fixed a typo that translated \UNNNNNNNN characters that were not valid in
+    the current locale encoding as \uNNNNNNNN.
+
+dd. Fixed an issue that could cause bash to print timing statistics for the
+    wrong command when `set -e' causes a command to fail.
+
+ee. Bash now runs the exit trap in function context if a failed command in
+    the function causes the shell to exit.
+
+ff. Some fixes to how subshells modify $SHLVL.
+
+gg. Fixed a bug that caused `mapfile -t' not to remove the delimiter when the
+    delimiter is > 128 in the current encoding.
+
+hh. Fixed a problem that could cause the shell to attempt to free unallocated
+    memory if an expansion error occurred.
+
+ii. Fixed a bug in the bash malloc implementation of malloc_usable_size. Bash
+    did not use it, but it could cause problems with library functions that
+    did.
+
+jj. If the `exec' builtin fails, and the shell does not exit, it restores
+    trapped signals to their trapped state.
+
+kk. Fixed a bug that could cause variable assignment arguments to `declare' to
+    expand variables using attributes that the call to declare was turning off.
+
+ll. Fixed a bug with LINENO and arithmetic for commands.
+
+mm. Fixed a posix-mode bug that caused tildes not to be expanded after an
+    unquoted colon on the right side of an assignment statement.
+
+nn. Fixed a problem with `caller' and line numbers when executing an ERR trap.
+
+oo. Fixed a problem that could make the value returned by ${a:=b} not be the
+    final value assigned to a (e.g., if `a' has an attribute that modifies
+    the value on assignment).
+
+pp. Fixed a problem with saving multi-line here-documents to the history list
+    where the here-document delimiter does not appear on the first line.
+
+qq. Fixed a bug with using += to assign to dynamic variables like RANDOM.
+
+rr. Fixed a bug that caused `set -n' to modify $? if set after execution had
+    started.
+
+ss. Builtins like printf/read/wait now behave more consistently when assigning
+    arbitrary keys to associative arrays (like `]'. when appropriately quoted).
+
+tt. Fixed a problem with here-document collection printing the wrong prompt
+    when parsing a compound list in an interactive shell.
+
+uu. Fixed a problem with quoting shell expansion characters (like `$') when
+    they appear in a tab-completed word along with characters that do need
+    quoting (e.g.. $HOME/VirtualBox VMs).
+
+2. Changes to Readline
+
+a. Fixed a problem with cleaning up active marks when using callback mode.
+
+b. Fixed a problem with arithmetic comparison operators checking the version.
+
+c. Fixed a problem that could cause readline not to build on systems without
+   POSIX signal functions.
+
+d. Fixed a bug that could cause readline to crash if the application removed
+   the callback line handler before readline read all typeahead.
+
+e. Added additional checks for read errors in the middle of readline commands.
+
+f. Fixed a redisplay problem that occurred when switching from the digit-
+   argument prompt `(arg: N)' back to the regular prompt and the regular
+   prompt contained invisible characters.
+
+g. Fixed a problem with restoring the prompt when aborting an incremental
+   search.
+
+h. Fix a problem with characters > 128 not being displayed correctly in certain
+   single-byte encodings.
+
+i. Fixed a problem with unix-filename-rubout that caused it to delete too much
+   when applied to a pathname consisting only of one or more slashes.
+
+j. Fixed a display problem that caused the prompt to be wrapped incorrectly if
+   the screen changed dimensions during a call to readline() and the prompt
+   became longer than the screen width.
+
+k. Fixed a problem that caused the \r output by turning off bracketed paste
+   to overwrite the line if terminal echo was disabled.
+
+l. Fixed a bug that could cause colored-completion-prefix to not display if
+   completion-prefix-display-length was set.
+
+m. Fixed a problem with line wrapping prompts when a group of invisible
+   characters runs to the right edge of the screen and the prompt extends
+   longer then the screen width.
+
+n. Fixed a couple problems that could cause rl_end to be set incorrectly by
+   transpose-words.
+
+3. New Features in Bash
+
+a. The bash malloc returns memory that is aligned on 16-byte boundaries.
+
+b. There is a new internal timer framework used for read builtin timeouts.
+
+c. Rewrote the command substitution parsing code to call the parser recursively
+   and rebuild the command string from the parsed command. This allows better
+   syntax checking and catches errors much earlier. Along with this, if
+   command substitution parsing completes with here-documents remaining to be
+   read, the shell prints a warning message and reads the here-document bodies
+   from the current input stream.
+
+d. The `ulimit' builtin now treats an operand remaining after all of the options
+   and arguments are parsed as an argument to the last command specified by
+   an option. This is for POSIX compatibility.
+
+e. Here-document parsing now handles $'...' and $"..." quoting when reading the
+   here-document body.
+
+f. The `shell-expand-line' and `history-and-alias-expand-line' bindable readline
+   commands now understand $'...' and $"..." quoting.
+
+g. There is a new `spell-correct-word' bindable readline command to perform
+   spelling correction on the current word.
+
+h. The `unset' builtin now attempts to treat arguments as array subscripts
+   without parsing or expanding the subscript, even when `assoc_expand_once'
+   is not set.
+
+i. There is a default value for $BASH_LOADABLES_PATH in config-top.h.
+
+j. Associative array assignment and certain instances of referencing (e.g.,
+   `test -v') now allow `@' and `*' to be used as keys.
+
+k. Bash attempts to expand indexed and associative array subscripts only
+   once when executing shell constructs and word expansions.
+
+l. The `unset' builtin allows a subscript of `@' or `*' to unset a key with
+   that value for associative arrays instead of unsetting the entire array
+   (which you can still do with `unset arrayname'). For indexed arrays, it
+   removes all elements of the array without unsetting it (like `A=()').
+
+m. Additional builtins (printf/test/read/wait) do a better job of not
+   parsing array subscripts if array_expand_once is set.
+
+n. New READLINE_ARGUMENT variable set to numeric argument for readline commands
+   defined using `bind -x'.
+
+o. The new `varredir_close' shell option causes bash to automatically close
+   file descriptors opened with {var}<fn and other styles of varassign
+   redirection unless they're arguments to the `exec' builtin.
+
+p. The `$0' special parameter is now set to the name of the script when running
+   any (non-interactive) startup files such as $BASH_ENV.
+
+q. The `enable' builtin tries to load a loadable builtin using the default
+   search path if `enable name' (without any options) attempts to enable a
+   non-existent builtin.
+
+r. The `printf' builtin has a new format specifier: %Q. This acts like %q but
+   applies any specified precision to the original unquoted argument, then
+   quotes and outputs the result.
+
+s. The new `noexpand_translations' option controls whether or not the translated
+   output of $"..." is single-quoted.
+
+t. There is a new parameter transformation operator: @k. This is like @K, but
+   expands the result to separate words after word splitting.
+
+u. There is an alternate array implementation, selectable at `configure' time,
+   that optimizes access speed over memory use (use the new configure
+    --enable-alt-array-implementation option).
+
+v. If an [N]<&WORD- or [N]>&WORD- redirection has WORD expand to the empty
+   string, treat the redirection as [N]<&- or [N]>&- and close file descriptor
+   N (default 0).
+
+w. Invalid parameter transformation operators are now invalid word expansions,
+   and so cause fatal errors in non-interactive shells.
+
+x. New shell option: patsub_replacement. When enabled, a `&' in the replacement
+   string of the pattern substitution expansion is replaced by the portion of
+   the string that matched the pattern. Backslash will escape the `&' and
+   insert a literal `&'.
+
+y. `command -p' no longer looks in the hash table for the specified command.
+
+z. The new `--enable-translatable-strings' option to `configure' allows $"..."
+   support to be compiled in or out.
+
+aa. The new `globskipdots' shell option forces pathname expansion never to
+    return `.' or `..' unless explicitly matched. It is enabled by default.
+
+bb. Array references using `@' and `*' that are the value of nameref variables
+    (declare -n ref='v[@]' ; echo $ref) no longer cause the shell to exit if
+    set -u is enabled and the array (v) is unset.
+
+4. New Features in Readline
+
+a. There is now an HS_HISTORY_VERSION containing the version number of the
+   history library for applications to use.
+
+b. History expansion better understands multiple history expansions that may
+   contain strings that would ordinarily inhibit history expansion (e.g.,
+   `abc!$!$').
+
+c. There is a new framework for readline timeouts, including new public
+   functions to set timeouts and query how much time is remaining before a
+   timeout hits, and a hook function that can trigger when readline times
+   out. There is a new state value to indicate a timeout.
+
+d. Automatically bind termcap key sequences for page-up and page-down to
+   history-search-backward and history-search-forward, respectively.
+
+e. There is a new `fetch-history' bindable command that retrieves the history
+   entry corresponding to its numeric argument. Negative arguments count back
+   from the end of the history.
+
+f. `vi-undo' is now a bindable command.
+
+g. There is a new option: `enable-active-region'. This separates control of
+   the active region and bracketed-paste. It has the same default value as
+   bracketed-paste, and enabling bracketed paste enables the active region.
+   Users can now turn off the active region while leaving bracketed paste
+   enabled.
+
+h. rl_completer_word_break_characters is now `const char *' like
+   rl_basic_word_break_characters.
+
+i. Readline looks in $LS_COLORS for a custom filename extension
+   (*.readline-colored-completion-prefix) and uses that as the default color
+   for the common prefix displayed when `colored-completion-prefix' is set.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.1-rc3, and
+the previous version, bash-5.1-rc2.
+
+1. Changes to Bash
+
+a. The `assoc_expand_once' option now affects the evaluation of the -v primary
+   to test and the [[ compound command.
+
+2. Changes to Readline
+
+a. Fixed a bug that could cause point to be set beyond the end of the line
+   buffer when aborting an incremental search.
+
+3. New Features in Bash
+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.1-rc2, and
+the previous version, bash-5.1-rc1.
+
+1. Changes to Bash
+
+a. Process substitutions started from an interactive shell no longer have their
+   standard input implicitly redirected from /dev/null.
+
+b. Fixed an issue with setting the SIGINT trap handler in an interactive shell
+   when temporarily running $PROMPT_COMMAND non-interactively.
+
+2. Changes to Readline
+
+a. Terminals that are named "dumb" or unknown do not enable bracketed paste
+   by default.
+
+b. Ensure that disabling bracketed paste turns off highlighting the incremental
+   search string when the search is successful.

+   double quotes.
+
+c. Fixed a case where the shells's exit status could be greater than 255.
+
+d. Modified changed to process substitution so the executed command has its
+   stdin redirected from /dev/null if it was previously interactive and
+   reading commands from the terminal.
+
+2. New Features in Bash
+
+a. There is a new contributed loadable builtin: asort.
+

+   initialized.
+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.1-beta, and
+the previous version, bash-5.1-alpha.
+
+1. Changes to Bash
+

+
+d. A few minor changes to move potential uses of stdio functions out of signal
+   handling paths.
+
+e. Make sure SIGCHLD is blocked in all cases where waitchld() is not called
+   from a signal handler.
+
+f. Changed `command' builtin processing so it no longer starts an extra process
+   when run asynchronously (command x &).
+
+g. Avoid performing tilde expansion after `:' in words that look like assignment
+   statements when in posix mode.
+
+h. Slight changes to how the `complete' builtin prints out options and actions
+   for completion specifications.
+
+i. Several changes to how `local -' restores the values of options and
+   $SHELLOPTS.
+
+j. Don't treat a word in a compound assignment as an assignment statement
+   unless it has a valid subscript before the `='.
+
+k. Fixed a bug with the DEBUG trap and process substitution that caused the
+   terminal's process group to be set incorrectly.
+
+l. Fixed a bug that left readline's signal handlers installed while running a
+   shell command from a bindable readline command.
+
+m. Fixed the `fc' builtin to clamp out of range history specifications at the
+   boundaries of the history list for POSIX conformance.
+
+n. Fixed a bug that caused ${foo@a} to treat foo as an unset variable if it
+   was an array without a value for subscript 0/"0" but had other set
+   elements.
+
+o. Fixed a bug that caused the history code to attempt to parse command
+   substitutions looking for shell comments before adding them to the history,
+   even while parsing here-documents.
+
+p. Fixed a bug that could cause a syntax error in a command read by `eval' to
+   exit an interactive shell.
+
+2. New Features in Bash

+
+c. Bash attempts to optimize away forks in the last command in a function body
+   under appropriate circumstances.
+
+d. The globbing code now uses fnmatch(3) to check collation elements (if
+   available) even in cases without multibyte characters.
+
+e. The `fg' and `bg' builtins now return an error in a command substitution
+   when asked to restart a job inherited from the parent shell.
+
+f. The shell now attempts to unlink all FIFOs on exit, whether a consuming

+
+3. Changes to Readline
+
+a. Make sure that all undo groups are closed when leaving vi insertion mode.
+
+b. Make sure that the vi-mode `C' and `c' commands enter insert mode even if
+   the motion command doesn't have any effect.
+
+c. Fixed several potential memory leaks in the callback mode context handling.
+
+d. If readline is handling a SIGTTOU, make sure SIGTTOU is blocked while
+   executing the terminal cleanup code, since it's no longer run in a signal
+   handling context.
+
+4. New Features in Readline
+
+a. The signal cleanup code now blocks SIGINT while processing after a SIGINT.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.1-alpha, and
+the previous version, bash-5.0-release.
+
+1. Changes to Bash
+
+a. Fixed a bug that caused a posix-mode shell to not exit if the return builtin
+   was executed outside a function or dot script.
+
+b. Fixed a bug where `declare +f' could potentially turn off the function
+   attribute.
+
+c. Restored bash-4.4 pathname expansion behavior when a word to be expanded had
+   only backslashes, not any of the other globbing characters. This came after
+   an extensive POSIX group discussion (interp #1234).
+
+d. There are more changes to avoid performing word expansions multiple times on
+   arithmetic expressions.
+
+e. Fixed a bug with alias expansion when the alias ends with a TAB.
+
+f. Fixed a bug that caused programmable completion to return an error if the
+   shell function name supplied as an argument to `complete -F' was invalid.
+
+g. There are several fixes to buffer overflows found as the result of fuzzing
+   with random input.
+
+h. Fixed a bug that caused the edit-and-execute-command editing command to
+   start with the previous history line if invoked on an empty line.
+
+i. Fixed a bug that potentially caused `bind --help' to change readline's
+   output stream.
+
+j. Turning off posix mode now restores the vi-insertion mode binding for TAB
+   that was in effect when posix mode was enabled.
+
+k. Restore the previous state of job control being enabled if `exec' fails in
+   an interactive shell.
+
+l. Fixed a bug that caused the terminal's process group to be set incorrectly
+   if job control was turned off before starting an interactive shell.
+
+m. Fixed a bug that caused a crash when HISTSIZE=0.
+
+n. Fixed a word expansion bug that caused null strings on the rhs of expansions
+   to be discarded incorrectly.
+
+o. History list management does a better job of handling the situation where
+   the number of history entries from the current shell session is greater than
+   the number of entries in the history list.
+
+p. Fixed a bug that caused the `fc' builtin to attempt to dereference a newly-
+   freed history entry.
+
+q. Fixed a bug that made the `Q' variable transformation not work well with
+   `set -u'.
+
+r. There are several word expansion fixes for expanding $* and $@ in contexts
+   where word splitting is not going to be performed, since each positional
+   parameter must expand to a separate word.
+
+s. Fixed a bug that could cause ^D to exit bash immediately even if there were
+   stopped jobs.
+
+t. Fixed a bug with double-quoting and backslash-quoting strings containing
+   multibyte characters for reuse.
+
+u. Fixed a bug that caused the line number to be reported incorrectly if the
+   shell executed a (command) subshell.
+
+v. Fixed a bug that caused the shell to fail to reap process substitutions
+   when they went out of scope, which had unpredictable results.
+
+w. Fixed a bug that caused null strings in arguments to [[ conditional command
+   operators to compare incorrectly.
+
+x. Changed the behavior of `wait' without arguments to only wait for background
+   processes the current shell instance started, not background children it may
+   have inherited.
+
+y. Fixed a bug that could cause command substitution to leave file descriptors
+   open if the shell received many SIGINTs.
+
+z. Bash now behaves better if the `**' filename expansion operator encounters a
+   symbolic link to a directory, avoiding more cases where it might return
+   duplicate pathnames.
+
+aa. Programmable completion now canonicalizes directory names in the same way
+    as bash word completion, so `..' is handled consistently.
+
+bb. Fixed a bug when using RETURN as the delimiter to the read builtin; it
+    caused readline to set the binding for RETURN incorrectly.
+
+cc. Fixed a bug that caused `history -d' to delay printing an out-of-range
+    error message.
+
+dd. Fixed a bug with `bash -c command' where `command' ends with an expanded
+    alias.
+
+ee. Fixed a bug that could result in `history -n' adding spurious line feeds to
+    commands in the history list.
+
+ff. The $RANDOM random number generator now XORs the top and bottom halves of
+    the internal 32-bit value to introduce more randomness. Setting the shell
+    compatibility level to 50 or lower undoes this.
+
+gg. Fixed several problems caused by running the DEBUG trap on simple commands
+    executed as part of a pipeline.
+
+ii. Fixed a bug that didn't allow `bind -r' to remove the binding for \C-@.
+
+jj. Several fixes to the bash-backward-shellword bindable readline command to
+    behave better when at the last character on the line.
+
+kk. If `set -x' is enabled, bash doesn't print a command twice if it's run by
+    the `command' builtin.
+
+ll. Fixed a bug with printing function definitions containing here documents.
+
+mm. Fixed a bug that could cause the `bind' builtin to set $? to -1.
+
+nn. Fixed a bug that didn't reset the timezone information correctly when the
+    TZ variable was unset.
+
+oo. Fixed several issues with assigning an associative array variable using a
+    compound assignment that expands the value of the same variable.
+
+pp. Fixed several places where the shell set $? without setting PIPESTATUS.
+
+qq. Fixed a problem with glob bracket expressions containing invalid character
+    classes, collating symbols, or equivalence classes -- they should not
+    require a closing right bracket.
+
+rr. Fixed a bug where running a builtin in a subshell did not run the EXIT trap.
+
+ss. Fixed several problems with posix-mode variable assignments preceding
+    shell function calls and posix special builtins, so that they create and
+    modify variables at the current scope.
+
+tt. Fix history initialization so `bash +o history' works as expected.
+
+uu. Fixed a bug in the bindable edit-and-execute-command command that could
+    interfere with the shell's parsing state.
+
+vv. Fixed an issue with nested traps running command substitutions in command
+    lines with command substitutions.
+
+ww. Fixed a bug with globbing pathnames that contain invalid multibyte
+    characters (sequences that don't correspond to a character in the current
+    locale).
+
+xx. Fixed a bug that caused the shell not to exit if a function definition
+    failed while errexit was enabled.
+
+yy. Process substitution processes now get their input from /dev/null, since
+    they are asynchronous, not interactive, and not jobs.
+
+zz. Setting nocaseglob no longer turns on case-insensitive regexp matching.
+
+aaa. Fixed a bug that resulted in extra blank lines being added to some history
+     entries containing here-documents.
+
+bbb. Fixed a bug that resulted in incorrect matching of some patterns in word
+     expansion if they expanded to the empty string.
+
+ccc. Fixed here-string expansion so it behaves the same as expansion of the
+     rhs of an assignment statement.
+
+ddd. Changed here-document parsing to no longer allow the end of the here
+     document to delimit a command substitution.
+
+eee. Several fixes to history expansion: multiple :p modifiers work, a ^ word
+     designator works as part of a range, and a `-' is treated as part of a
+     search string if it immediately follows a `!'.
+
+fff. Fixed a bug in pattern substitution with null matches in a string
+     containing multibyte characters.
+
+ggg. Unbinding a key sequence bound with `bind -x' now removes the key sequence
+     from the additional keymap `bind -x' uses.
+
+hhh. Fixed a bug with command start detection for completion so that it doesn't
+     mistake brace expansion for the start of a command.
+
+iii. Fixed a bug that caused local variables with the same name as variables
+     appearing in a function's temporary environment to not be marked as local.
+
+jjj. Fixed a bug that could cause SIGCHLD to be blocked when executing return
+     or exec in the rightmost pipeline element with lastpipe enabled.
+
+kkk. Fixed a bug that could result in commands without the execute bit set
+     being added to the command hash table.
+
+lll. Fixed a bug that allowed non-digits to follow the `#' in a `base#number'
+     integer constant.
+
+mmm. Fixed a bug that made `time -- command' attempt to execute `--'.
+
+nnn. Fixed a couple of bugs with variable transformation using arrays
+     subscripted with `*' or `@'.
+
+ooo. A failure to create a variable using `declare' in a function no longer
+     causes the function to return immediately.
+
+ppp. Fixed a bug that could cause the := word expansion to add a non-null
+     value if attempting to assign a null string when double-quoted.
+
+qqq. Fixed a bug that could cause backslashes quoting double quotes in here
+     document bodies to not be removed when expanding the body.
+
+rrr. Fixed a bug that caused commands following a subshell while the shell is
+     reading input from stdin but not interactive, while job control is
+     enabled, to be executed twice.
+
+sss. Fixed a bug where receiving SIGTERM from a different process while
+     readline was active could cause the shell to terminate.
+
+ttt. In posix mode, running a trap after the read builtin now sees the exit
+     status of the read builtin (e.g., 130 after a SIGINT) in $?.
+
+uuu. Fixed a bug with nameref variables referencing array subscripts used in
+     arithmetic expressions.
+
+vvv. Fixed a bug that caused the pipeline process group id to be reset in the
+     middle of a command list run by a shell started to run a command
+     substitution.
+
+www. Restricted shells can no longer read and write history files with pathnames
+     containing slashes.
+
+xxx. Fixed a couple of problems with 0 and -0 used as arguments to `fc' when
+     not listing commands from the history.
+
+yyy. When `test' is supplied four or more arguments, treat an argument that
+     looks like an operator (e.g., -e), but is in a place where only a string
+     is valid, as a string, as it would be when using the POSIX rules, instead
+     of an operator with a missing argument.
+
+zzz. There is no `compat50' shopt option. Changes to the shell compatibility
+     level should use the BASH_COMPAT variable.
+
+aaaa. Redirection failures with compound commands are now treated as errors
+      that cause the shell to exit if `errexit' is enabled.
+
+bbbb. Redirection failure error messages no longer expand the word in the
+      redirection again.
+
+cccc. History expansion is no longer performed while parsing a here-document
+      inside a command substitution.
+
+2. Changes to Readline
+
+a. There are a number of fixes that were found as the result of fuzzing with
+   random input.
+
+b. Changed the revert-all-at-newline behavior to make sure to start at the end
+   of the history list when doing it, instead of the line where the user hit
+   return.
+
+c. When parsing `set' commands from the inputrc file or an application, readline
+   now allows trailing whitespace.
+
+d. Fixed a bug that left a file descriptor open to the history file if the
+   file size was 0.
+
+e. Fixed a problem with binding key sequences containing meta characters.
+
+f. Fixed a bug that caused the wrong line to be displayed if the user tried to
+   move back beyond the beginning of the history list, or forward past the end
+   of the history list.
+
+g. If readline catches SIGTSTP, it now sets a hook that allows the calling
+   application to handle it if it desires.
+
+h. Fixed a redisplay problem with a prompt string containing embedded newlines.
+
+i. Fixed a problem with completing filenames containing invalid multibyte
+   sequences when case-insensitive comparisons are enabled.
+
+j. Fixed a redisplay problem with prompt strings containing invisible multibyte
+   characters.
+
+k. Fixed a problem with multibyte characters mapped to editing commands that
+   modify the search string in incremental search.
+
+l. Fixed a bug with maintaining the key sequence while resolving a bound
+   command in the presence of ambiguous sequences (sequences with a common
+   prefix), in most cases while attempting to unbind it.
+
+m. Fixed several buffer overflows found as the result of fuzzing.
+
+n. Reworked backslash handling when translating key sequences for key binding
+   to be more uniform and consistent, which introduces a slight backwards
+   incompatibility.
+
+o. Fixed a bug with saving the history that resulted in errors not being
+   propagated to the calling application when the history file is not writable.
+
+p. Readline only calls chown(2) on a newly-written history file if it really
+   needs to, instead of having it be a no-op.
+
+q. Readline now behaves better when operate-and-get-next is used when the
+   history list is `full': when there are already $HISTSIZE entries.
+
+r. Fixed a bug that could cause vi redo (`.') of a replace command not to work
+   correctly in the C or POSIX locale.
+
+s. Fixed a bug with vi-mode digit arguments that caused the last command to be
+   set incorrectly. This prevents yank-last-arg from working as intended, for
+   example.
+
+3. New Features in Bash
+
+a. `bind -x' now supports different bindings for different editing modes and
+   keymaps.
+
+b. Bash attempts to optimize the number of times it forks when executing
+   commands in subshells and from `bash -c'.
+
+c. Here documents and here strings now use pipes for the expanded document if
+   it's smaller than the pipe buffer size, reverting to temporary files if it's
+   larger.
+
+d. There are new loadable builtins: mktemp, accept, mkfifo, csv, cut/lcut
+
+e. In posix mode, `trap -p' now displays signals whose disposition is SIG_DFL
+   and those that were SIG_IGN when the shell starts.
+
+f. The shell now expands the history number (e.g., in PS1) even if it is not
+   currently saving commands to the history list.
+
+g. `read -e' may now be used with arbitrary file descriptors (`read -u N').
+
+h. The `select' builtin now runs traps if its internal call to the read builtin
+   is interrupted by a signal.
+
+i. SRANDOM: a new variable that expands to a 32-bit random number that is not
+   produced by an LCRNG, and uses getrandom/getentropy, falling back to
+   /dev/urandom or arc4random if available. There is a fallback generator if
+   none of these are available.
+
+j. shell-transpose-words: a new bindable readline command that uses the same
+   definition of word as shell-forward-word, etc.
+
+k. The shell now adds default bindings for shell-forward-word,
+   shell-backward-word, shell-transpose-words, and shell-kill-word.
+
+l. Bash now allows ARGV0 appearing in the initial shell environment to set $0.
+
+m. If `unset' is executed without option arguments, bash tries to unset a shell
+   function if a name argument cannot be a shell variable name because it's not
+   an identifier.
+
+n. The `test -N' operator uses nanosecond timestamp granularity if it's
+   available.
+
+o. Bash posix mode now treats assignment statements preceding shell function
+   definitions the same as in its default mode, since POSIX has changed and
+   no longer requires those assignments to persist after the function returns
+   (POSIX interp 654).
+
+p. BASH_REMATCH is no longer readonly.
+
+q. wait: has a new -p VARNAME option, which stores the PID returned by `wait -n'
+   or `wait' without arguments.
+
+r. Sorting the results of pathname expansion now uses byte-by-byte comparisons
+   if two strings collate equally to impose a total order; the result of a
+   POSIX interpretation (#963 and #1070).
+
+s. Bash now allows SIGINT trap handlers to execute recursively.
+
+t. Bash now saves and restores state around setting and unsetting posix mode,
+   instead of having unsetting posix mode set a known state.
+
+u. Process substitution is now available in posix mode.
+
+v. READLINE_MARK: a new variable available while executing commands bound with
+   `bind -x', contains the value of the mark.
+
+w. Bash removes SIGCHLD from the set of blocked signals if it's blocked at shell
+   startup.
+
+x. `test -v N' can now test whether or not positional parameter N is set.
+
+y. `local' now honors the `-p' option to display all local variables at the
+    current context.
+
+z. The `@a' variable transformation now prints attributes for unset array
+   variables.
+
+aa. The `@A' variable transformation now prints a declare command that sets a
+    variable's attributes if the variable has attributes but is unset.
+
+bb. `declare' and `local' now have a -I option that inherits attributes and
+    value from a variable with the same name at a previous scope.
+
+cc. When run from a -c command, `jobs' now reports the status of completed jobs.
+
+dd. New `U', `u', and `L' parameter transformations to convert to uppercase,
+    convert first character to uppercase, and convert to lowercase,
+    respectively.
+
+ee. PROMPT_COMMAND: can now be an  array variable, each element of which can
+    contain a command to be executed like a string PROMPT_COMMAND variable.
+
+ff. `ulimit' has a -R option to report and set the RLIMIT_RTTIME resource.
+
+gg. Associative arrays may be assigned using a list of key-value pairs within
+    a compound assignment. Compound assignments where the words are not of
+    the form [key]=value are assumed to be key-value assignments. A missing or
+    empty key is an error; a missing value is treated as NULL. Assignments may
+    not mix the two forms.
+
+hh. New `K' parameter transformation to display associative arrays as key-
+    value pairs.
+
+ii. Writing history to syslog now handles messages longer than the syslog max
+    length by writing multiple messages with a sequence number.
+
+jj. SECONDS and RANDOM may now be assigned using arithmetic expressions, since
+    they are nominally integer variables. LINENO is not an integer variable.
+
+kk. Bash temporarily suppresses the verbose option when running the DEBUG trap
+    while running a command from the `fc' builtin.
+
+ll. `wait -n' now accepts a list of job specifications as arguments and will
+    wait for the first one in the list to change state.
+
+mm. The associative array implementation can now dynamically increase the
+    size of the hash table based on insertion patterns.
+
+nn. HISTFILE is now readonly in a restricted shell.
+
+oo. The bash malloc now returns memory that is 16-byte aligned on 64-bit
+    systems.
+
+4. New Features in Readline
+
+a. If a second consecutive completion attempt produces matches where the first
+   did not, treat it as a new completion attempt and insert a match as
+   appropriate.
+
+b. Bracketed paste mode works in more places: incremental search strings, vi
+   overstrike mode, character search, and reading numeric arguments.
+
+c. Readline automatically switches to horizontal scrolling if the terminal has
+   only one line.
+
+d. Unbinding all key sequences bound to a particular readline function now
+   descends into keymaps for multi-key sequences.
+
+e. rl-clear-display: new bindable command that clears the screen and, if
+   possible, the scrollback buffer (bound to emacs mode M-C-l by default).
+
+f. New active mark and face feature: when enabled, it will highlight the text
+   inserted by a bracketed paste (the `active region') and the text found by
+   incremental and non-incremental history searches. This is tied to bracketed
+   paste and can be disabled by turning off bracketed paste.
+
+g. Readline sets the mark in several additional commands.
+
+h. Bracketed paste mode is enabled by default.
+
+i. Readline tries to take advantage of the more regular structure of UTF-8
+   characters to identify the beginning and end of characters when moving
+   through the line buffer.
+
+j. The bindable operate-and-get-next command (and its default bindings) are
+   now part of readline instead of a bash-specific addition.

+   to an associative array with assoc_expand_once enabled.
+
+e. Fixed a bug that could cause a huge memory allocation when completing a
+   word beginning with an invalid tilde expansion.

+
+h. Fixed a bug that caused the output of `set' to cut off some variables before
+   printing the value.
+
+i. Treat a failure to assign a variable when using the ${x:=value} expansion
+   as an expansion error, so non-interactive posix-mode shells exit
+
+j. Fixed a problem when expanding $* in a context where word splitting is not
+   performed when IFS is NULL.
+
+k. Temp files used to store here documents are forced readable, no matter what
+   the user's umask says.
+
+l. Fixed a problem where an interrupted brace expansion could cause the shell
+   to attempt to free an invalid memory location.
+
+m. Make sure to check for any terminating signals after running a trap
+   handler; don't wait until the next time we process traps.
+
+n. Fixed a bug that caused "return" to act like a special builtin with respect
+   to variable assignments even when preceded by "command".
+
+o. POSIX-mode shells now return failure if the cd builtin fails due to the
+   absolute directory name being longer than PATH_MAX, instead of trying
+   again with a relative pathname.
+
+p. Fixed a problem with FUNCNAME occasionally being visible when not executing
+   a shell function.
+
+q. Fixed a problem with the expansions performed on the WORD in the case
+   command.
+
+r. Fixed a slight POSIX compatibility when removing "IFS whitespace" during
+   word splitting and the read builtin.
+
+s. Fixed a problem with expanding an array with subscript `*' when all the

+
+a. Fixed a bug with adding multibyte characters to an incremental search string.
+
+b. Fixed a bug with redoing text insertions in vi mode.
+

+
+g. Trap execution now honors the (internal) max invocations of `eval', since
+   traps are supposed to be executed as if using `eval'.
+
+h. The $_ variable doesn't change when the shell executes a command that forks.
+
+i. The `kill' builtin now supports -sSIGNAME and -nSIGNUM, even though

+
+j. POSIX mode now enables the `shift_verbose' option.
+
+4. New Features in Readline
+
+a. Readline now allows application-defined keymap names; there is a new public
+   function, rl_set_keymap_name(), to do that.
+
+b. The "Insert" keypad key, if available, now puts readline into overwrite
+   mode.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.0-beta, and
+the previous version, bash-5.0-alpha.
+
+1.  Changes to Bash
+
+a. Fixed a bug that allowed subshells to "inherit" enclosing loops -- this
+   is where POSIX says the subshell is not "enclosed" by the loop.
+
+b. Added more UTF-8-specific versions of multibyte functions, and optimized
+   existing functions if the current locale uses UTF-8 encoding.
+
+c. In POSIX mode, assignments preceding regular builtins should not persist
+   when the builtin completes.
+
+d. Added additional checks to special array assignment (e.g., BASH_ALIASES)
+   so it can't be used to bypass validity checks performed in other places.
+
+e. The `!!' history expansion now refers to the previous history entry as
+   expected, even if used on the second or subsequent line of a multi-line
+   history entry.
+
+f. Fixed a bug that could cause the shell to dereference a NULL pointer if
+   the environment (`environ') is set to NULL.
+
+g. Bash uses slightly better integer overflow handling for brace sequence
+   expansion on systems where ints are 32 bits and intmax_t is 64 bits.
+
+h. Fixed a bug setting attributes for a variable named as an argument to
+   `declare' that also appears as a nameref in the temporary environment.
+
+i. Fixed several bugs that could cause assignments to namerefs to create
+   variables with invalid names.
+
+j. Fixed a bug that could result in the SIGINT handler being set incorrectly
+   in asynchronous subshells.
+
+k. Fixed a bug that could cause `bash -t' to not execute the specified command.
+
+l. Fixed several bugs that caused the shell to operate on the wrong variable
+   when using namerefs with the same name as a global variable in shell
+   functions.
+
+m. Internal changes to how the shell handles variables with invalid names in
+   the initial environment and to prevent variables with invalid names from
+   being added to the environment instead of passing them on to children.
+
+n. Changes to make sure that an expansion that results in a quoted null string
+   is reflected in the expansion, even if the word expands to nothing.
+
+o. Changes to make sure that $* and ${array[*]} (and $@/${array[@]}) expand
+   the same way after the recent changes for POSIX interpretation 888.
+
+p. Saving and restoring the positional parameters at function entry and exit
+   is considerably more efficient; noticeably so when there are large numbers
+   of positional parameters.
+
+q. Fixed a bug that caused `lastpipe' and `pipefail' to return an incorrect
+   status for the pipeline if there was more than one external command in a
+   loop body appearing in the last pipeline element.
+
+r. Fixed a bug that caused value conversion errors with the printf builtin's
+   %u and %f conversion specifications and invalid constants.
+
+2.  Changes to Readline
+
+a. Added more UTF-8-specific versions of multibyte functions, and optimized
+   existing functions if the current locale uses UTF-8 encoding.
+
+b. Fixed a problem with bracketed-paste inserting more than one character and
+   interacting with other readline functions.
+
+c. Fixed a bug that caused the history library to attempt to append a history
+   line to a non-existent history entry.
+
+d. If using bracketed paste mode, output a newline after the \r that is the
+   last character of the mode disable string to avoid overwriting output.
+
+e. Fixes to the vi-mode `b', `B', `w', `W', `e', and `E' commands to better
+   handle multibyte characters.
+
+f. Fixed a redisplay problem that caused an extra newline to be generated on
+   accept-line when the line length is exactly the screenwidth.
+
+3.  New Features in Bash
+
+a. Bash no longer allows variable assignments preceding a special builtin that
+   changes variable attributes to propagate back to the calling environment
+   unless the compatibility level is 44 or lower.
+
+b. You can set the default value for $HISTSIZE at build time in config-top.h.
+
+c. The `complete' builtin now accepts a -I option that applies the completion
+   to the initial word on the line.
+
+d. The internal bash malloc now uses mmap (if available) to satisfy requests
+   greater than 128K bytes, so free can use mfree to return the pages to the
+   kernel.
+
+e. The shell doesn't automatically set BASH_ARGC and BASH_ARGV at startup
+   unless it's in debugging mode, as the documentation has always said, but
+   will dynamically create them if a script references them at the top level
+   without having enabled debugging mode.
+
+f. The localvar_inherit option will not attempt to inherit a value from a
+   variable of an incompatible type (indexed vs. associative arrays, for
+   example).
+
+g. The `globasciiranges' option is now enabled by default; it can be set to
+   off by default at configuration time.
+
+4.  New Features in Readline
+
+a. The history expansion library now understands command and process
+   substitution and extended globbing and allows them to appear anywhere in a
+   word.
+
+b. The history library has a new variable that allows applications to set the
+   initial quoting state, so quoting state can be inherited from a previous
+   line.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.0-alpha, and
+the previous version, bash-4.4-release.
+
+1.  Changes to Bash
+
+a. Fixed a bug that could cause traps in background jobs to give the terminal
+   to the wrong process group.
+
+b. Fixed a bug that caused `kill -l 0' to print an out-of-range error.
+
+c. Fixed a problem that could result in here-documents being displayed in
+   the wrong order.
+
+d. Fixed a number of out-of-bounds and free memory read errors found via
+   fuzzing.
+
+e. Fixed a subshell inheritance problem that could cause a subshell to wait for
+   the wrong process.
+
+f. Fixed a bug that caused SHLVL to be incremented one too many times when
+   creating subshells.
+
+g. A job dying due to SIGINT can now interrupt sourcing a file in a shell with

+
+l. The shell does a better job of saving multi-line history entries with
+   embedded comments.
+
+m. Fixed a bug that could cause quoted bracket expressions in regular expression
+   arguments to `[[' to not match correctly.
+
+n. Fixed a bug that could cause an IFS character in a word to result in an
+   extra '\001' character in the expansion.
+
+o. A trailing backslash in a glob pattern can match a trailing backslash in the
+   string.
+
+p. Fixed a memory leak in the process creation code path when job control is
+   enabled.
+
+q. Fixed a bug that caused `printf' to output broken surrogate pairs for
+   Japanese locales.
+
+r. Fixed a bug that caused a SIGINT generated from `kill' in a dot script to
+   kill an interactive shell.
+
+s. Fixed a bug that could cause the `read' builtin to not fully read a
+   multibyte character.
+
+t. Fixed a bug that could cause identifiers to be evaluated in conditional
+   arithmetic expressions even when evaluation is suppressed.
+
+u. Fixed a bug that could result in command substitution, when executed in a
+   context where word splitting is not performed, to leave a stray '\001'
+   character in the string.
+
+v. Fixed a bug that could cause history expansion to be disabled in a non-
+   interactive shell even if `-o histexpand' is supplied at startup.
+
+w. Fixed a bug that caused `read -N' to strip leading whitespace IFS characters.
+
+x. Fixed a bug that caused spurious tilde expansion in arithmetic expressions.
+
+y. If indirect expansion attempts to indirectly reference through an unset
+   variable, report an error.
+
+z. Added a guard to prevent the shell from looping while receiving an endless
+   stream of SIGTTIN at shell startup.
+
+aa. Fixed a bug with parsing here documents inside a command substitution when
+    looking for the closing delimiter.
+
+bb. Fixed a bug that caused printf to not quote all <blank> characters in the
+    current locale when using the `%q' format specifier.
+
+cc. Fixed a bug with bash's internal buffered I/O system that caused the input
+    pointer to not be reset when read(2) returned an EOF.
+
+dd. Bash now installs its SIGWINCH signal handler with SA_RESTART, so it will
+    not interrupt open/read/write system calls.
+
+ee. The ERR trap now reports line numbers more reliably.
+
+ff. The shell no longer tries to manipulate the terminal process group if a
+    command or process substitution is killed by SIGTERM when job control is
+    enabled.
+
+gg. Fixed a bug that caused extglob patterns to match filenames beginning with
+    a period.
+
+hh. File descriptors open for writing to here documents are no longer available
+    to subshells.
+
+ii. Make sure word completion doesn't perform command or process substitution.
+
+jj. Fixed a bug with parsing $$'...' inside a command substitution.
+
+kk. Fixed a bug that caused bash to remove backslash-newline pairs from the
+    body of a here-document with a quoted delimiter inside a command
+    substitution.
+
+ll. Fixed a bug that could cause the shell to hang when adding a pid to the
+    table of background process exit statuses.
+
+mm. Fixed a bug that could cause 0x01 characters to be doubled in the output
+    of process substitution.
+
+nn. Restricted shells now clear the hash table before making the PATH variable
+    read-only.
+
+oo. There are a number of changes to the expansion of $* and $@ in contexts
+    where word splitting does not occur (quoted and unquoted), with IFS set
+    to NULL or a non-standard value, mostly to deal with the consequences of
+    the behavior defined in Posix interpretation 888.
+
+pp. There are a number of changes to nameref variable handling to avoid
+    creating variables with invalid names.
+
+qq. A non-interactive posix mode shell no longer exits when an assignment
+    statement fails if the assignment is utimately being performed by the
+    `command' builtin.
+
+rr. When using character class names for globbing, don't allow case
+    insensitivity, even if nocaseglob is enabled.
+
+ss. Fixed a bug that allowed some redirections to stay in place if a later
+    redirection failed.
+
+tt. Fixed a bug in how command and process substitutions are recognized within
+    other parameter expansions.
+
+uu. Fixed a bug that caused bash to loop under certain circumstances when
+    performing arithmetic expansion on a variable whose value is an invalid
+    expression.
+
+vv. Fixed a bug that could cause bash to expand aliases inappropriately while
+    parsing compound commands like `case'.

+    various prompt strings.
+
+aaa. Fixed a bug that could cause a core dump if READLINE_LINE was unset
+     inside a shell function bound to a key sequence with `bind -x'.
+
+bbb. Fixed a bug that could cause bash to not read a token terminator correctly
+     if a command substitution was used inside an arithmetic `for' command.
+
+ccc. Fixed problems that could occur with a fatal arithmetic expansion error
+     in a context (like prompt expansion) where you can't jump back to the
+     top level.
+
+ddd. Expression errors in arithmetic `for' commands are treated more like
+     shell syntax errors.
+
+eee. Fixed a parser synchronization error resulting from a syntax error
+     followed immediately by an EOF.
+
+fff. When executing a shell function, the first line in the function ($LINENO)
+     is line 1 instead of line 0, as Posix requires.
+
+ggg. In Posix mode, bash will canonicalize the value of PWD it inherits from
+     the environment and use that to set its idea of the current directory.
+
+hhh. If LINENO is exported, bash needs to regenerate its value each time it
+     constructs the environment.
+
+iii. Fixed a bug with restoring the SIGINT handler when using `wait -n'.
+
+jjj. Make sure the `coproc' command returns an appropriate status if the NAME
+     argument is invalid.
+
+kkk. Fixed a problem with arithmetic expressions containing array references
+     that contain arithmetic expressions with syntax errors.
+
+lll. The `select' command and help builtin will use $COLUMNS before the window
+     size returned from the kernel as the terminal width.
+
+mmm. `read -n 0' and `read -N 0' now try a zero-length read in an attempt to
+     detect file descriptor errors.
+
+nnn. The `read' builtin now does a better job of acting on signals that don't
+     interrupt read(2).
+
+ooo. Fixed some cases where `printf -v' did not return failure status on a
+     variable assignment error.
+
+ppp. Fixed temporary environment propagation back to the current environment
+     so that it doesn't happen for special builtins run by the `command'
+     builtin.
+
+qqq. Fixed a bug when searching for the end of a here-document delimiter in a
+     command substitution.
+
+rrr. Fixed a bug that could cause `cd ${DIRSTACK[0]}' to fail.
+
+sss. Fixed a bug that could cause reserved words to not be recognized in a
+     for statement without the `in' inside a command substitution.
+
+ttt. Fixed a bug that could cause a double-free in a timed command with an
+     expansion error.
+
+uuu. Fixed a bug that could cause a core dump if a script switches from a UTF-8
+     locale to a different locale after displaying a lone surrogate character.
+
+vvv. Fixed cases where bash prematurely removed FIFOs attached to process
+     substitutions.
+
+www. Fixed a problem with calculating the size of the table that stores exit
+     statuses from background processes when the child process resource limit
+     is very large.
+
+xxx. Fixed a memory leak with functions using `return' when using FIFOs for
+     standard input.
+
+yyy. `wait' without arguments attempts to wait for all active process
+     substitution processes.
+
+zzz. Fixed a bug where an indirect parameter was subjected to word splitting
+     when trying to find the indirected variable name.
+
+aaaa. Fixed a bug that could allow restricted shell users to add commands to
+      the hash table.
+
+bbbb. When using the `!(patlist)' extended globbing operator, a filename
+      beginning with a `.' that doesn't match any of the patterns is not
+      returned as a match if leading dots must be matched explicitly.
+
+cccc. Fixed a bug that could cause line number and source file information for
+      a function definition to be incorrect if there are multiple definitions.
+
+dddd. Fixed a bug that could cause builtins like `readonly' to behave
+      differently when applied to arrays and scalar variables within functions.
+
+eeee. Fixed a bug that could cause alias expansion to add an extra space to
+      a quoted string that begins outside the alias expansion.
+
+ffff. Fixed a bug that could result in unwanted alias expansion after timing
+      the null command.
+
+gggg. Fixed a bug that could cause a core dump if a timestamp in a history
+      file overflowed a time_t.
+
+hhhh. Restricted shells can no longer redirect from /dev/tcp or /dev/udp, since
+      the kernel calls make those file descriptors read-write.
+
+iiii. Fixed a problem with splitting double-quoted words for programmable
+      completion when the double quote immediately follows another word
+      delimiter.
+
+jjjj. Fixed a bug resulting in a use-after-free if two file descriptors share
+      the same input buffer.
+
+kkkk. The error message resulting from ${x:?} and ${x?} now differs depending
+      on whether the variable is null or unset.
+
+llll. In Posix mode, the shell exits if a variable assignment fails and precedes
+      an empty simple command (after expansion).
+
+mmmm. Fixed a timing problem with SIGALRM that could cause the read builtin to
+      drop characters.
+
+nnnn. Added code to deal with kill(2) failing to send the shell a fatal signal
+      due to Linux pid namespace peculiarities.
+
+oooo. Fixed a bug that made \C-@ (NUL) unusable in key sequences used for
+      `bind -x' commands.
+
+pppp. Fixed a bug that could cause SIGINT recursion when running an external
+      command in a trap the shell takes after a command exits due to SIGINT.
+
+qqqq. Make sure the shell turns off job control before running the command-
+      not-found handle, so the command doesn't try to manipulate process
+      groups.
+
+rrrr. Fixed a problem with timing process substitutions that caused the shell
+      to print timing information for the calling command.
+
+ssss. Fixed a bug that caused backquotes in a here-document delimiter to mark
+      the delimiter as quoted (inhibiting expansion of the here-document
+      contents).
+
+tttt. Fixed several problems with 0x01 and 0x177 in case pattern lists and
+      conditional command pattern matches.
+
+uuuu. Fixed a bug that could cause the pattern matching engine to not recognize
+      locale-specific character classes.
+
+vvvv. The auto-configuration now tests for /dev/stdin and /dev/fd independently.
+
+wwww. The `globstar' code now skips over symbolic links to directories,
+      preventing them from being scanned twice.
+
+xxxx. When running `bind -x' commands, bash now sets READLINE_POINT based on
+      the number of characters in the readline line buffer, not the number of
+      bytes.
+
+yyyy. Fixed a problem that could cause recursive trap evaluation of the RETURN
+      trap when using `eval return'.
+
+zzzz. Fixed a bug with expanding 0x01 in an unquoted here-document.
+
+aaaaa. The process substitution code now closes and unlinks FIFOs when the
+       process on the other side exits, in order to prevent SIGPIPE or
+       waiting until a FIFO opened for read has a writer.
+
+bbbbb. Fixed a bug with recursive calls to the parser overwriting the token in
+       an {id}>foo construct.
+
+ccccc. After a Posix discussion, the pattern matching engine just skips over
+       invalid character classes in bracket expressions, instead of matching
+       them like individual characters in the expression.
+
+ddddd. Fixed a posix-mode problem with variable scoping when creating variables
+       from assignment statements preceding special builtins.
+
+eeeee. Fixed a bug that could cause patterns containing backslashes to not be
+       run through the pattern matching engine.
+
+fffff. Fixed a bug that could cause redirections to compound commands to not
+       be `undone' if the file descriptor in the redirection was closed when
+       the redirection was initially processed.
+
+ggggg. Fixed a bug that could cause buffer corruption when using `bind -x' in
+       a command execute as a result of a key binding installed by `bind -x'.
+
+2.  Changes to Readline
+
+a. Added a guard to prevent nested macros from causing an infinite expansion
+   loop.
+
+b. Instead of allocating enough history list entries to hold the maximum list
+   size, cap the number allocated initially.
+
+c. Added a strategy to avoid allocating huge amounts of memory if a block of
+   history entries without timestamps occurs after a block with timestamps.
+
+d. Added support for keyboard timeouts when an ESC character is the last
+   character in a macro.
+
+e. There are several performance improvements when in a UTF-8 locale.
+
+f. Readline does a better job of preserving the original set of blocked
+   signals when using pselect() to wait for input.
+
+g. Fixed a bug that caused multibyte characters in macros to be mishandled.
+
+h. Fixed several bugs in the code that calculates line breaks when expanding
+   prompts that span several lines, contain multibyte characters, and contain
+   invisible character seqeuences.
+
+i. Fixed several bugs in cursor positioning when displaying lines with prompts
+   containing invisible characters and multibyte characters.
+
+j. When performing case-insensitive completion, Readline no longer sorts the
+   list of matches unless directed to do so.
+
+k. Fixed a problem with key sequences ending with a backslash.
+
+l. Fixed out-of-bounds and free memory read errors found via fuzzing.
+
+m. Fixed several cases where the mark was set to an invalid value.
+
+n. Fixed a problem with the case-changing operators in the case where the
+   lower and upper case versions of a character do not have the same number
+   of bytes.
+
+o. Handle incremental and non-incremental search character reads returning EOF.
+
+p. Handle the case where a failing readline command at the end of a multi-key
+   sequence could be misinterpreted.
+
+q. The history library now prints a meaningful error message if the history
+   file isn't a regular file.
+
+r. Fixed a problem with vi-mode redo (`.') on a command when trying to replace
+   a multibyte character.
+
+s. The key binding code now attempts to remove a keymap if a key unbinding
+   leaves it empty.
+
+t. Fixed a line-wrapping issue that caused problems for some terminal
+   emulators.
+
+u. If there is a key bound to the tty's VDISCARD special character, readline
+   disables VDISCARD while it is active.
+
+v. Fixed a problem with exiting bracketed paste mode on terminals that assume
+   the bracketed paste mode character sequence contains visible characters.
+
+w. Fixed a bug that could cause a key binding command to refer to an
+   uninitialized variable.
+
+3.  New Features in Bash
+
+a. The `wait' builtin can now wait for the last process substitution created.
+
+b. There is an EPOCHSECONDS variable, which expands to the time in seconds
+   since the Unix epoch.
+
+c. There is an EPOCHREALTIME variable, which expands to the time in seconds
+   since the Unix epoch with microsecond granularity.
+
+d. New loadable builtins: rm, stat, fdflags.
+
+e. BASH_ARGV0: a new variable that expands to $0 and sets $0 on assignment.
+
+f. When supplied a numeric argument, the shell-expand-line bindable readline
+   command does not perform quote removal and suppresses command and process
+   substitution.
+
+g. `history -d' understands negative arguments: negative arguments offset from
+   the end of the history list.
+
+h. The `name' argument to the `coproc' reserved word now undergoes word
+   expansion, so unique coprocs can be created in loops.
+
+i. A nameref name resolution loop in a function now resolves to a variable by
+   that name in the global scope.
+
+j. The `wait' builtin now has a `-f' option, which signifies to wait until the
+   specified job or process terminates, instead of waiting until it changes
+   state.
+
+k. There is a define in config-top.h that allows the shell to use a static
+   value for $PATH, overriding whatever is in the environment at startup, for
+   use by the restricted shell.
+
+l. Process substitution does not inherit the `v' option, like command
+   substitution.
+
+m. If a non-interactive shell with job control enabled detects that a foreground
+   job died due to SIGINT, it acts as if it received the SIGINT.
+
+n. The SIGCHLD trap is run once for each exiting child process even if job
+   control is not enabled when the shell is in Posix mode.
+
+o. A new shopt option: localvar_inherit; if set, a local variable inherits the
+   value of a variable with the same name at the nearest preceding scope.
+
+p. `bind -r' now checks whether a key sequence is bound before binding it to
+   NULL, to avoid creating keymaps for a multi-key sequence.
+
+q. A numeric argument to the line editing `operate-and-get-next' command
+   specifies which history entry to use.
+
+r. The positional parameters are now assigned before running the shell startup
+   files, so startup files can use $@.
+
+s. There is a compile-time option that forces the shell to disable the check
+   for an inherited OLDPWD being a directory.
+
+t. The `history' builtin can now delete ranges of history entries using
+   `-d start-end'.
+
+u. The `vi-edit-and-execute-command' bindable readline command now puts readline
+   back in vi insertion mode after executing commands from the edited file.
+
+v. The command completion code now matches aliases and shell function names
+   case-insensitively if the readline completion-ignore-case variable is set.
+
+w. There is a new `assoc_expand_once' shell option that attempts to expand
+   associative array subscripts only once.
+
+x. The shell only sets up BASH_ARGV and BASH_ARGC at startup if extended
+   debugging mode is active. The old behavior of unconditionally setting them
+   is available as part of the shell compatibility options.
+
+y. The `umask' builtin now allows modes and masks greater than octal 777.
+
+z. The `times' builtin now honors the current locale when printing a decimal
+   point.
+
+aa. There is a new (disabled by default, undocumented) shell option to enable
+    and disable sending history to syslog at runtime.
+
+4.  New Features in Readline
+
+a. Non-incremental vi-mode search (`N', `n') can search for a shell pattern, as
+   Posix specifies (uses fnmatch(3) if available).
+
+b. There are new `next-screen-line' and `previous-screen-line' bindable
+   commands, which move the cursor to the same column in the next, or previous,
+   physical line, respectively.
+
+c. There are default key bindings for control-arrow-key key combinations.
+
+d. A negative argument (-N) to `quoted-insert' means to insert the next N
+   characters using quoted-insert.
+
+e. New public function: rl_check_signals(), which allows applications to
+   respond to signals that readline catches while waiting for input using
+   a custom read function.
+
+f. There is new support for conditionally testing the readline version in an
+   inputrc file, with a full set of arithmetic comparison operators available.
+
+g. There is a simple variable comparison facility available for use within an
+   inputrc file. Allowable operators are equality and inequality; string
+   variables may be compared to a value; boolean variables must be compared to
+   either `on' or `off'; variable names are separated from the operator by
+   whitespace.

+    number of any signal readline has caught but not yet handled.
+
+b.  New application-settable variable: rl_persistent_signal_handlers: if set
+    to a non-zero value, readline will enable the readline-6.2 signal handler

+    rl_callback_handler_install is called and removed removed when a complete
+    line has been read.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.4-beta2, and
+the previous version, bash-4.4-rc1.

+
+b.  Fixed a bug that caused subshells to free trap strings associated with
+    inherited signals.

+    associated with enabling an option, instead of just marking the option
+    as enabled.
+
+d.  Fixed a bug that allowed assignments to BASH_CMDS when the shell was in
+    restricted mode.
+
+e.  Fixed a bug caused by an accidental omission of part of the original patch

+    circuiting.
+
+i.  Fixed a memory leak in the code that removes duplicate history entries.
+
+j.  There are a number of bug fixes to coproc, mapfile, declare, unset,
+    and assignment statements that prevent nameref variables from creating
+    and unsetting variables with invalid names.
+
+k.  Fixed a bug that caused variables to be inadvertently marked as both an
+    associative and an indexed array.
+
+l.  Fixed a bug that caused `bash -c' to not run a trap specified in the
+    command string.
+
+j.  There are a number of bug fixes to coproc, mapfile, declare, and assignment
+    statements that prevent nameref variables from overwriting or modifying
+    attributes of readonly variables.
+
+k.  Fixed a bug that caused command substitution to attempt to set the
+    terminal's process group incorrectly.
+    
+l.  Fixed a bug that could cause prompt string expansion to display error
+    messages when the `nounset' shell option is set.
+
+m.  Fixed a bug that caused "$@" to not expand to an empty string under the
+    circumstances when Posix says it should ("${@-${@-$@}}").
+
+n.  Fixed several bugs caused by referencing nameref variables whose values
+    are names of unset variables (or names that are valid for referencing
+    but not assignment), including creating variables in the temporary
+    environment.
+
+o.  Function tracing and error tracing are disabled if --debugger is supplied
+    at startup but the shell can't find the debugger start file.
+
+p.  Fixed a bug when IFS is used as the control variable in a for statement.
+
+q.  Fixed a bug with SIGINT received by a command substitution in an interactive
+    shell.
+
+r.  The checks for nameref variable self-references are more thorough.
+
+s.  Fixed several bugs with multi-line aliases.
+
+t.  Fixed `test' to handle the four-argument case where $1 == '(' and

+u.  Fixed a bug in the expansion of $* in the cases where word splitting is
+    not performed.
+
+v.  Fixed a bug in execution of case statements where IFS includes the
+    pattern matching characters.
+
+2.  Changes to Readline
+
+a.  When refreshing the line as the result of a key sequence, Readline attempts
+    to redraw only the last line of a multiline prompt.
+
+b.  Fixed an issue that caused completion of git commands to display
+    incorrectly when using colored-completion-prefix.
+
+c.  Fixed several redisplay bugs having to do with multibyte characters and
+    invisible characters in prompt strings.
+
+3.  New Features in Bash
+
+a.  Value conversions (arithmetic expansions, case modification, etc.) now
+    happen when assigning elements of an array using compound assignment.
+
+b.  There is a new option settable in config-top.h that makes multiple
+    directory arguments to `cd' a fatal error.
+
+c.  Bash now uses mktemp() when creating internal temporary files; it produces
+    a warning at build time on many Linux systems.
+
+4.  New Features in Readline
+
+a.  The default binding for ^W in vi mode now uses word boundaries specified
+    by Posix (vi-unix-word-rubout is bindable command name).
+
+b.  rl_clear_visible_line: new application-callable function; clears all
+    screen lines occupied by the current visible readline line.
+
+c.  rl_tty_set_echoing: application-callable function that controls whether
+    or not readline thinks it is echoing terminal output.
+
+d.  Handle >| and strings of digits preceding and following redirection
+    specifications as single tokens when tokenizing the line for history
+    expansion.
+
+e.  Fixed a bug with displaying completions when the prefix display length
+    is greater than the length of the completions to be displayed.
+
+f.  The :p history modifier now applies to the entire line, so any expansion
+    specifying :p causes the line to be printed instead of expanded.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.4-rc1, and
+the previous version, bash-4.4-beta.
+
+1.  Changes to Bash
+
+a.  Fixed several problems with bash completion not special-casing bash syntax
+    constructs.

+c.  Fixed a bug that caused prompt expansion to loop when PS1 contained a
+    syntax error.
+
+d.  Fixed a bug that caused the ${array[@]@A} expansion to split the results
+    even when double-quoted.
+
+e.  There is a new implementation of the code that saves the last CHILD_MAX
+    exited background pids so their status can be queried later.
+
+f.  Bash-4.4 can now be configured and built on very old versions of Solaris 2.
+
+g.  Fixed problems with --help support for several builtins.
+
+h.  Fixed values added to BASH_SOURCE and BASH_LINENO for functions inherited
+    from the environment.

+    under certain circumstances.
+
+j.  Fixed a bug that caused `fc' to return an incorrect exit status when
+    executing commands from the history list.
+
+k.  Fixed a bug that caused the shell to exit when a process substitution
+    received a SIGINT when run in certain terminal emulators.
+
+l.  EXECIGNORE now honors the setting of `extglob' when attempting to match
+    executable names.
+
+m.  Fixed a bug where `return' used the wrong exit status when executed in a
+    DEBUG trap.
+
+n.  Fixed a bug that caused a command containing a here-document and an escaped
+    newline to be stored in the history list incorrectly.
+
+o.  Fixed a bug that caused set -e to be honored in cases of builtins invoking
+    other builtins when it should be ignored.
+
+p.  Fixed a bug that caused `readonly' and `export' to create local array
+    variables when used within shell functions.
+
+q.  Fixed a bug that allowed subshells begun to execute process substitutions
+    to have access to the command's temporary environment.
+
+r.  Fixed a bug that could cause the shell to dump core when receiving a
+    SIGCHLD for which a trap has been set while running in posix mode.
+
+s.  Fixed a bug that caused bash to not restore BASH_ARGC, BASH_ARGV,
+    BASH_SOURCE, BASH_LINENO, and FUNCNAME if the shell received a SIGINT
+    while reading commands from a file while executing  `.'.
+
+t.  Fixed a bug that caused the `-o history' option to have no effect when
+    supplied on the command line when starting a new shell.
+
+u.  Fixed a bug that caused history expansions occurring in command
+    substitutions to not be performed.
+
+v.  Fixed a bug that caused `eval' run in a non-interactive shell to disable
+    history expansion for the remainder of the shell script, even if the script
+    had previously enabled it.
+
+w.  Fixed a bug that caused "$@" to not expand to multiple words when IFS is set
+    to the empty string.
+
+x.  Fixed a bug that caused process and command substitution to inherit output
+    buffered in the stdio library but not written.
+
+y.  Fixed a bug that caused a terminating signal received during `echo' to run
+    an exit trap in a signal handler context.
+
+z.  Fixed a bug that caused a builtin command containing a process substitution
+    to return the wrong exit status.
+
+aa. Fixed a bug that caused `()' subshells with piped input to incorrectly
+    redirect the standard input of some of the commands in the subshell from
+    /dev/null.
+
+bb. The history builtin now uses more descriptive error messages for missing or
+    invalid timestamps.
+
+2.  Changes to Readline
+
+a.  The history file writing functions only attempt to create and use a backup
+    history file if the history file exists and is a regular file.
+
+b.  Fixed an out-of-bounds read in readline's internal tilde expansion
+    interface.
+
+c.  Fixed several redisplay bugs with prompt strings containing multibyte
+    and non-visible characters whose physical length is longer than the screen
+    width.
+
+d.  Fixed a redisplay bug with prompt strings containing invisible characters
+    whose physical length exceeds the screen width and using incremental search.
+
+e.  Readline prints more descriptive error messages when it encounters errors
+    while reading an inputrc file.
+
+f.  Fixed a bug in the character insertion code that attempts to optimize
+    typeahead when it reads a character that is not bound to self-insert and
+    resets the key sequence state.
+
+3.  New Features in Bash
+
+a.  BASH_COMPAT and FUNCNEST can be inherited and set from the shell's initial
+    environment.
+
+b.  inherit_errexit: a new `shopt' option that, when set, causes command
+    substitutions to inherit the -e option.  By default, those subshells disable
+    -e.  It's enabled as part of turning on posix mode.
+
+c.  New prompt string: PS0.  Expanded and displayed by interactive shells after
+    reading a complete command but before executing it.
+
+d.  Interactive shells now behave as if SIGTSTP/SIGTTIN/SIGTTOU are set to
+    SIG_DFL when the shell is started, so they are set to SIG_DFL in child
+    processes.
+
+e.  Posix-mode shells now allow double quotes to quote the history expansion
+    character.
+
+f.  OLDPWD can be inherited from the environment if it names a directory.
+
+g.  Shells running as root no longer inherit PS4 from the environment, closing
+    a security hole involving PS4 expansion performing command substitution.
+
+h.  If executing an implicit `cd' when the `autocd' option is set, bash will
+    now invoke a function named `cd' if one exists before executing the `cd'
+    builtin.
+
+4.  New Features in Readline
+
+a.  If an incremental search string has its last character removed with DEL,
+    the resulting empty search string no longer matches the previous line.
+
+b.  If readline reads a history file that begins with `#' (or the value of
+    the history comment character) and has enabled history timestamps, the
+    history entries are assumed to be delimited by timestamps.  This allows
+    multi-line history entries.
+
+c.  Readline now throws an error if it parses a key binding without a
+    terminating `:' or whitespace.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.4-beta, and
+the previous version, bash-4.4-alpha.

+
+e.  Fixed a bug that caused the && and || operators to be incorrectly optimized.
+
+f.  The shell now undoes redirections before exiting the shell when the `-e'
+    option is enabled, and a shell function fails.
+
+g.  History expansion now skips over the history expansion character in command
+    and process substitution.
+
+h.  Fixed a bug that caused stray '\001' characters to be added to the output
+    of `declare -p'.
+
+i.  Fixed a memory leak when processing declare commands that perform compound
+    array assignments.
+
+j.  Fixed a bug that could cause the shell to crash when reading input from a
+    file and the limit on open file descriptors is high.
+
+k.  Fixed a bug that caused the ERR and RETURN traps to be unset if they were
+    set in a shell function but unset previously.
+
+l.  Fixed a bug that caused several signals to be ignored if `exec' failed in
+    an interactive shell.
+
+m.  A posix-mode non-interactive shell now considers a parameter expansion error
+    to be a fatal error.
+
+n.  The `time' command now prints timing statistics for failed commands when

+
+o.  Fixed a bug that caused the shell to crash when attempting to indirectly
+    expand a shell variable with an invalid name.
+
+p.  Fixed a bug that caused the shell to crash when running a trap containing
+    a process substitution.
+
+q.  Bash now prints the keyword `function' before a function with the same name
+    as a reserved word when using `declare -f' to avoid parse errors when
+    reusing the output as input.
+
+r.  Fixed a bug that caused the shell to crash when using declare -g to attempt
+    to redefine an existing global indexed array variable as an associative
+    array.
+
+s.  Fixed a memory leak that occurred when interrupting brace expansions
+    generating a sequence.
+
+t.  Fixed a bug that resulted in alias expansion in redirections.
+
+u.  The `declare -a' and `declare -A' commands now print fewer warnings when
+    attempting to create and initialize an array at the same time, but
+    relying on word expansions to construct the compound assignment.
+
+v.  The `help' builtin now behaves better in locales where each wide
+    character occupies more than one display column.
+
+w.  The `read' builtin no longer has a possible race condition when a timeout
+    occurs.
+
+x.  Fixed several expansion problems encountered when IFS="'".
+
+y.  Fixed a problem with the expansion of $'\c?'.
+
+z.  Bash no longer splits the expansion of here-strings, as the documentation
+    has always said.
+
+aa. Bash now puts `s' in the value of $- if the shell is reading from standard
+    input, as Posix requires.
+
+bb. Fixed a bug that caused the shell to crash if invoked with a NULL
+    environment.
+
+cc. The shell now only trusts an inherited value for $PWD if it begins with a
+    `/'.
+

+
+ee. Fixed a bug that could cause the shell to crash when processing nested here
+    documents inside a command substitution.
+
+ff. Array keys and values are now displayed using $'...' quoting where
+    appropriate.

+
+ii. Fixed a bug that could cause the shell to crash if variable indirection
+    resulted in a NULL variable.
+
+jj. Fixed a bug that could cause the shell to crash if a long string contained
+    multiple unterminated parameter expansion constructs.
+
+kk. Improved the code that acts on SIGINT received while waiting for a child
+    process only if the child exits due to SIGINT.
+
+ll. $BASH_SUBSHELL now has more consistent values in asynchronous simple
+    commands.
+
+2.  Changes to Readline
+

+    likely to collide with files.
+
+b.  Fixed a bug that caused vi-mode character search to misbehave when
+    running in callback mode.
+
+c.  Fixed a bug that caused output to be delayed when input is coming from a
+    macro in vi-mode.
+
+d.  Fixed a bug that caused the vi-mode `.' command to misbehave when redoing
+    a multi-key key sequence via a macro.
+
+e.  Fixed a bug that caused problems with applications that supply their own
+    input function when performing completion.
+
+f.  When read returns -1/EIO when attempting to read a key, return an error
+    instead of line termination back to the caller.
+
+g.  Updated tty auditing feature based on patch from Red Hat.
+
+h.  Fixed a bug that could cause the history library to crash on overflows
+    introduced by malicious editing of timestamps in the history file.
+
+3.  New Features in Bash
+
+a.  `make install' now installs the example loadable builtins and a set of
+    bash headers to use when developing new loadable builtins.
+
+b.  `enable -f' now attempts to call functions named BUILTIN_builtin_load when
+    loading BUILTIN, and BUILTIN_builtin_unload when deleting it.  This allows
+    loadable builtins to run initialization and cleanup code.
+
+c.  There is a new BASH_LOADABLES_PATH variable containing a list of directories
+    where the `enable -f' command looks for shared objects containing loadable
+    builtins.
+
+d.  The `complete_fullquote' option to `shopt' changes filename completion to
+    quote all shell metacharacters in filenames and directory names.
+
+e.  The `kill' builtin now has a `-L' option, equivalent to `-l', for
+    compatibility with Linux standalone versions of kill.
+
+4.  New Features in Readline
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.4-alpha, and
+the previous version, bash-4.3-release.
+
+1.  Changes to Bash
+
+a.  A bug that caused pipelines to be corrupted while running the DEBUG trap
+    was fixed.
+
+b.  A bug that accidentally omitted the `-R' unary operator from `test' was
+    fixed.
+
+c.  A bug that could cause the shell to not restore the terminal's process
+    group on shell exit was fixed.
+
+d.  Several changes were made to programmable completion to accommodate
+    assumptions made by the bash-completion package.
+
+e.  Bash no longer inhibits C-style escape processing ($'...') while performing
+    pattern substitution word expansions.
+
+f.  Fixed a bug that caused `return' executed from a trap handler to use the
+    wrong return status when one was not supplied as an argument.
+
+g.  In Posix mode, defining a function with the same name as a special
+    builtin is now an error, fatal only when the shell is not interactive.
+
+h.  Fixed a bug that caused compound array assignments to discard unset or null
+    variables used as subscripts, thereby making it appear as if the index was
+    not present.
+
+i.  Fixed a bug that caused extended glob patterns to incorrectly match
+    filenames with a leading `.'.
+
+j.  Fixed a bug involving sign extension when reallocating the input line
+    after a history expansion, causing segmentation faults.
+
+k.  Bash now does a better job at identifying syntax errors during word
+    completion and tailoring completion appropriately.
+
+l.  Bash now uses the current locale's decimal point in command timing output.
+
+m.  Fixed a bug that caused segmentation faults while reading here documents if
+    PS2 contains a command substitution.
+
+n.  There are several changes to how $@ is expanded when unquoted but in a
+    context where word splitting is not performed (e.g., on the rhs of an
+    assignment or in a conditional command).
+
+o.  Bash now quotes command hash table entries that contain shell metacharacters
+    when displaying hash table contents.
+
+p.  Fixed a potential file descriptor leak when dup2() fails while performing a
+    redirection.
+
+q.  Fixed a bug that caused directory names evaluated during word completion to
+    be dequoted twice.
+
+r.  Fixed several bugs which could result in indirect variable expansion and
+    namerefs creating variables with invalid names or referencing variables
+    set to the empty string.
+
+s.  Fixed a bug that caused bash to not expand $0 in word expansions where it
+    should.
+
+t.  Fixed a bug that caused bash to perform process substitution if <(
+    appeared inside an arithmetic context.
+
+u.  Fixed a bug in extglob pattern parsing that caused slashes in the pattern
+    to be confused as directory names.
+
+v.  Fixed several bugs with treatment of invisible variables (variables with
+    attributes that are unset because they have never been assigned values).
+
+w.  Fixed a bug that caused the `read' builtin to not clean up readline's
+    state when using the -e and -t options together and the read timed out.
+
+x.  Fixed a bug that caused the shell to exit with the wrong (but non-zero)
+    value if a command was not found or was not executable.
+
+y.  Fixed a bug that caused the `time' reserved word to not be recognized as
+    such in all contexts where it should have been.
+
+z.  Fixed a bug that caused the shell to close process substitution file
+    descriptors when executing a script without the `#!' leading line.
+
+aa. Fixed a typo that caused the `compat42' shell option to set the wrong
+    compatibility level.
+
+bb. The shell now handles process substitution commands with embedded
+    parentheses the same way as it does when parsing command substitution.
+
+cc. Fixed a bug that caused nested pipelines and the `lastpipe' shell option
+    to produce core dumps.
+
+dd. Fixed a bug that caused patterns containing `*' to match pathnames in cases
+    where slashes must be matched explicitly.
+
+ee. Fixed a problem with patterns containing `:' in colon-separated variables
+    like GLOBIGNORE. 
+
+ff. Fixed a bug that caused indirect variable expansion using indexed arrays to
+    always use index 0.
+
+gg. Fixed a parsing problem that caused quoted newlines immediately following a
+    command substitution to be mishandled in certain cases.
+
+hh. Fixed a potential buffer overflow on systems without locale_charset or the
+    bash replacement.
+
+ii. Fixed a bug that caused background processes to modify the terminal's
+    process group under certain circumstances.
+
+jj. Asynchronous commands now always set $? to 0 and are not affected by
+    whether or not the command's exit status is being inverted.
+
+kk. Fixed a problem that caused a line ending with an escaped newline and
+    containingh a prior `eval' to be incorrectly parsed.
+
+ll. Fixed an issue with programmable completion and `!' in extglob patterns
+    used as arguments to `compgen -X'.
+
+mm. Word completion now treats the two-character token `>|' as requiring
+    filename expansion.
+
+nn. Bash no longer expands tildes in $PATH elements while in Posix mode.
+
+oo. Fixed a bug that caused bash to not clean up readline's state, including
+    the terminal settings, if it received a fatal signal while in a readline()
+    call (including `read -e' and `read -s').
+
+pp. Fixed bug that caused importing shell functions from the environment to
+    execute additional commands following the function.
+
+qq. Fixed a bug that caused the parser to return a lookahead character pushed
+    back by a previous call, even when on another line.
+
+rr. Fixed a bug that caused many here-documents or many nested case statements
+    to overflow an internal stack.
+
+ss. Changed the way bash encodes exported functions for inclusion in the
+    environment to avoid name collisions with valid variable names and to
+    indicate that they are exported functions.
+
+tt. Fixed a bug that could result in an invalid memory access when processing
+    a here document delimited by end of file or end of string.
+
+uu. Fixed a bug that could cause an invalid memory access if a command was run
+    before initializing the job control framework.
+
+vv. When in Posix mode, bash prints shell function definitions as Posix
+    specifies them, without the leading `function' keyword.
+
+ww. The variable attribute display builtins no longer display variables with
+    invalid names that were imported from the environment.
+
+xx. Fixed a bug that could allow `break' or `continue' executed from shell
+    functions to affect loops running outside of the function.
+
+yy. Fixed a bug that could cause a restricted shell to attempt to import shell
+    functions from the environment.
+
+zz. The shell now allows double-quoted identifiers in arithmetic expressions.
+
+aaa. Fixed a bug that could allow scalar variables subscripted using [@] in
+     word expansions to be incorrectly quoted.
+
+bbb. The shell now makes sure to ignore SIGTSTP/SIGTTIN/SIGTTOU in child
+     processes if they were ignored at shell startup, even if job control is
+     in effect.
+
+ccc. Fixed a bug that could cause $* to be split on spaces when IFS is set to
+     the empty string.
+
+ddd. Posix says that expanding $* in a pattern context where the expansion is
+     double-quoted should not treat $* as if it were double quoted.
+
+eee. Bash now restores getopts' internal state between calls to getopts even if
+     a shell function declares a local copy of OPTIND.
+
+fff. Fixed a bug that could cause `history -r' or `history -n' to read identical
+     lines from the history file more than once.
+
+ggg. The commands executed by `bind -x' now redisplay at most the final line
+     of a multi-line prompt, and those commands may return 124 to indicate that
+     the entire prompt should be redrawn.
+
+hhh. Fixed a bug that could cause `mapfile' to create variables with invalid
+     names.
+
+iii. The shell only goes into debugging mode when --debugger is supplied if
+     the debugger initialization file is present.
+
+jjj. Fixed a bug that disallowed an assignment to (implicit) subscript 0 of an
+     existing array in a declare command that set the readonly attribute.
+
+kkk. Fixed a bug that inadvertently allowed assignments to FUNCNAME to disable
+     its special status.
+
+lll. Appending to an existing array variable using the compound assignment
+     syntax (var+=(aaa)) should not affect assignments to existing subscripts
+     appearing in the compound assignment.
+
+mmm. Fixed a bug that could cause the shell to crash when a variable with a
+     null value was passed in the temporary environment and the variable's
+     attributes are modified using `declare' while performing a redirection.
+
+nnn. Fixed a bug in printf so that a missing precision specifier after a `.'
+     is treated as 0.
+
+ooo. Fixed a bug that attempted to use the internal command timing to time
+     pipeline components if the pipeline elements are separated by newlines.
+
+ppp. Fixed a bug that caused `declare -al foo=(ONE TWO THREE)' to not lowercase
+     the values on assignment.
+
+qqq. Bash does a better job of determining whether or not files are executable
+     when running on Windows, since the X_OK flag to access(2) is not supported.
+
+rrr. Fixed a bug that caused some of the shell's internal traps (e.g., ERR) to
+     be interrupted (and leave incorrect state) by pending SIGINTs.
+
+sss. Fixed a bug in the bash interface to history expansion to avoid attempting
+     expansion if the history expansion character occurs in a command
+     substitution.
+
+ttt. Fixed a bug that caused the select command to crash if the REPLY variable
+     ends up empty (e.g., if it's made readonly)
+
+uuu. Bash handles backslash-quoting of multibyte characters better when quoting
+     output that is intended to be reused.
+
+vvv. System-specific changes for: Windows, Cygwin.
+
+www. Fixes for upper and lower-casing multibyte characters, some locales have
+     characters whose upper and lowercase versions have different numbers of
+     bytes.
+
+xxx. Fixed a bug that caused the ERR trap in a shell function to have the
+     wrong value for $LINENO.
+
+yyy. Fixed a bug that resulted in incorrect quoting of regexps for the =~
+     operator when an open brace appears without a close brace.
+
+zzz. Fixed a bug in the array unset operation that caused it to attempt to
+     parse embedded single and double quotes.
+
+aaaa. Fixed a bug that caused $* to not expand with the first character of
+      $IFS as a separator in a context where word splitting will not take
+      place.
+
+bbbb. Fixed two bugs that could cause the shell to dereference a null pointer
+      while attempting to print an error message from arithmetic expansion.
+
+cccc. Fixed a bug that resulted in short-circuited evaluation when reading
+      commands from a string ending in an unquoted backslash, or when sourcing
+      a file that ends with an unquoted backslash.
+
+dddd. Fixed a bug that resulted in the no-fork optimization not cleaning up
+      any FIFOs created by process substitution.
+
+eeee. If the -T option is not set, allow the source builtin and shell functions
+      to set a DEBUG trap that persists after the sourced file or function
+      returns, instead of restoring the old (unset) value unconditionally.
+
+ffff. Fixed a bug that caused redirections to not be undone on some syntax
+      errors, e.g., when parsing a command substitution.
+
+gggg. Bash only adds asynchronous commands to the table of background pids
+      whose status it remembers, to avoid it growing too large during scripts
+      that create and reap large numbers of child processes.  This means that
+      `wait' no longer works on synchronous jobs, but $? can be used to get
+      the exit status in those cases.
+
+hhhh. Bash now checks whether or not a shell script argument is a directory
+      before trying to open it; Posix says implementations may allow open(2)
+      on a directory.
+
+iiii. Fixed a bug that could cause the shell to set the terminal's process
+      group to a background process group when running as part of a pipeline.
+
+jjjj. Made a few changes to strings to avoid possible potential negative effects
+      caused by malicious translations.
+
+kkkk. Fixed a bug that caused the `unset' builtin to continue to treat its
+      arguments as functions after unsetting a function when invoked with no
+      options.
+
+llll. Fixed a bug that would not replace empty strings using pattern
+      substitution even if the pattern matched the empty string.
+
+mmmm. Fixed a bug with word completion that prevented some characters from
+      being backslash-quoted (backquote, dollar sign).
+
+nnnn. Fixed a bug that prevented a command from the history re-executed by the
+      `fc' builtin from setting verbose mode.
+
+oooo. Fixed a bug that caused the shell to not enable and disable function
+      tracing with changes to the `extdebug' shell option.
+
+pppp. Fixed a bug that caused assignments to nameref variables pointing to
+      unset variables with attributes but no values to create variables with
+      incorrect names.
+
+qqqq. Fixed a bug that caused `unset' on nameref variables (without -n) to
+      unset the wrong variable under certain circumstances.
+
+rrrr. Fixed a bug that caused close braces occurring in brace expansions within
+      command substitutions to incorrectly terminate parameter expansions.
+
+ssss. Fixed a bug that caused `command -p' to temporarily alter $PATH.
+
+tttt. Fixed a bug that caused interactive shells compiled without job control
+      to return incorrect status values for child processes when running a
+      single command that creates enough children to use the entire PID space.
+
+uuuu. `esac' should not be recognized as a reserved word when it appears as the
+      second or later pattern in a case statement pattern list.
+
+vvvv. Fixed a bug that caused the completion code to read past the end of the
+      readline line buffer while skipping assignment statements to find the
+      command name.
+
+wwww. Fixed a bug that caused case statements within loops contained in a
+      command substitution to be parsed incorrectly.
+
+xxxx. Fixed a bug that could cause SIGCHLD handling to be delayed after
+      running `wait' with no arguments and interrupting it with ^C without
+      a trap handler installed.
+
+2.  Changes to Readline
+
+a.  A bug that caused vi-mode `.' to be unable to redo `c', `d', and `y'
+    commands with modifiers was fixed.
+
+b.  Fixed a bug that caused callback mode to dump core when reading a
+    multiple-key sequence (e.g., arrow keys).
+
+c.  Fixed a bug that caused the redisplay code to erase some of the line when
+    using horizontal scrolling with incremental search.
+
+d.  Readline's input handler now performs signal processing if read(2) is
+    interrupted by SIGALRM or SIGVTALRM.
+
+e.  Fixed a problem with revert-all-at-newline freeing freed memory.
+
+f.  Clarified the documentation for the history_quotes_inhibit_expansion
+    variable to note that it inhibits scanning for the history comment
+    character and that it only affects double-quoted strings.
+
+g.  Fixed an off-by-one error in the prompt printed when performing searches.
+
+h.  Use pselect(2), if available, to wait for input before calling read(2), so
+    a SIGWINCH can interrupt it, since it doesn't interrupt read(2).
+
+i.  Some memory leaks caused by signals interrupting filename completion have
+    been fixed.
+
+j.  Reading EOF twice on a non-empty line causes EOF to be returned, rather
+    than the partial line.  This can cause partial lines to be executed on
+    SIGHUP, for example.
+
+k.  Fixed a bug concerning deleting multibyte characters from the search
+    string while performing an incremental search.
+
+l.  Fixed a bug with tilde expanding directory names in filename completion.
+
+m.  Fixed a bug that did not allow binding sequences beginning with a `\'.
+
+n.  Fixed a redisplay bug involving incorrect line wrapping when the prompt
+    contains a multibyte character in the last screen column.
+
+o.  Fixed a bug that caused history expansion to disregard characters that are
+    documented to delimit a history event specifier without requiring `:'.
+
+p.  Fixed a bug that could cause reading past the end of a string when reading
+    the value when binding the set of isearch terminators.
+
+q.  Fixed a bug that caused readline commands that depend on knowing which
+    key invoked them to misbehave when dispatching key sequences that are
+    prefixes of other key bindings.
+
+r.  Paren matching now works in vi insert mode.
+
+3.  New Features in Bash
+
+a.  There is now a settable configuration #define that will cause the shell
+    to exit if the shell is running setuid without the -p option and setuid
+    to the real uid fails.
+
+b.  Command and process substitutions now turn off the `-v' option when
+    executing, as other shells seem to do.
+
+c.  The default value for the `checkhash' shell option may now be set at
+    compile time with a #define.
+
+d.  The `mapfile' builtin now has a -d option to use an arbitrary character
+    as the record delimiter, and a -t option  to strip the delimiter as
+    supplied with -d.
+
+e.  The maximum number of nested recursive calls to `eval' is now settable in
+    config-top.h; the default is no limit.
+
+f.  The `-p' option to declare and similar builtins will display attributes for
+    named variables even when those variables have not been assigned values
+    (which are technically unset).
+
+g.  The maximum number of nested recursive calls to `source' is now settable
+    in config-top.h; the default is no limit.
+
+h.  All builtin commands recognize the `--help' option and print a usage
+    summary.
+
+i.  Bash does not allow function names containing `/' and `=' to be exported.
+
+j.  The `ulimit' builtin has new -k (kqueues) and -P (pseudoterminals) options.
+
+k.  The shell now allows `time ; othercommand' to time null commands.
+
+l.  There is a new `--enable-function-import' configuration option to allow
+    importing shell functions from the environment; import is enabled by
+    default.
+
+m.  `printf -v var ""' will now set `var' to the empty string, as if `var=""'
+    had been executed.
+
+n.  GLOBIGNORE, the pattern substitution word expansion, and programmable
+    completion match filtering now honor the value of the `nocasematch' option.
+
+o.  There is a new ${parameter@spec} family of operators to transform the
+    value of `parameter'.
+
+p.  Bash no longer attempts to perform compound assignment if a variable on the
+    rhs of an assignment statement argument to `declare' has the form of a
+    compound assignment (e.g., w='(word)' ; declare foo=$w); compound
+    assignments are accepted if the variable was already declared as an array,
+    but with a warning.
+
+q.  The declare builtin no longer displays array variables using the compound
+    assignment syntax with quotes; that will generate warnings when re-used as
+    input, and isn't necessary.
+
+r.  Executing the rhs of && and || will no longer cause the shell to fork if
+    it's not necessary.
+
+s.  The `local' builtin takes a new argument: `-', which will cause it to save
+    the single-letter shell options and restore their previous values at
+    function return.
+
+t.  `complete' and `compgen' have a new `-o nosort' option, which forces
+    readline to not sort the completion matches.
+
+u.  Bash now allows waiting for the most recent process substitution, since it
+    appears as $!.
+
+v.  The `unset' builtin now unsets a scalar variable if it is subscripted with
+    a `0', analogous to the ${var[0]} expansion.
+
+w.  `set -i' is no longer valid, as in other shells.
+
+x.  BASH_SUBSHELL is now updated for process substitution and group commands
+    in pipelines, and is available with the same value when running any exit
+    trap.
+
+y.  Bash now checks $INSIDE_EMACS as well as $EMACS when deciding whether or
+    not bash is being run in a GNU Emacs shell window.
+
+z.  Bash now treats SIGINT received when running a non-builtin command in a
+    loop the way it has traditionally treated running a builtin command:
+    running any trap handler and breaking out of the loop.
+
+aa. New variable: EXECIGNORE; a colon-separate list of patterns that will
+    cause matching filenames to be ignored when searching for commands.
+
+bb. Aliases whose value ends in a shell metacharacter now expand in a way to
+    allow them to be `pasted' to the next token, which can potentially change
+    the meaning of a command (e.g., turning `&' into `&&').
+
+4.  New Features in Readline
+
+a.  The history truncation code now uses the same error recovery mechanism as
+    the history writing code, and restores the old version of the history file
+    on error.  The error recovery mechanism handles symlinked history files.
+
+b.  There is a new bindable variable, `enable-bracketed-paste', which enables
+    support for a terminal's bracketed paste mode.
+
+c.  The editing mode indicators can now be strings and are user-settable
+    (new `emacs-mode-string', `vi-cmd-mode-string' and `vi-ins-mode-string'
+    variables).  Mode strings can contain invisible character sequences.
+    Setting mode strings to null strings restores the defaults.
+
+d.  Prompt expansion adds the mode string to the last line of a multi-line
+    prompt (one with embedded newlines).
+
+e.  There is a new bindable variable, `colored-completion-prefix', which, if
+    set, causes the common prefix of a set of possible completions to be
+    displayed in color.
+
+f.  There is a new bindable command `vi-yank-pop', a vi-mode version of emacs-
+    mode yank-pop.
+
+g.  The redisplay code underwent several efficiency improvements for multibyte
+    locales.
+
+h.  The insert-char function attempts to batch-insert all pending typeahead
+    that maps to self-insert, as long as it is coming from the terminal.
+
+i.  rl_callback_sigcleanup: a new application function that can clean up and
+    unset any state set by readline's callback mode.  Intended to be used
+    after a signal.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.3-release, and
+the previous version, bash-4.3-rc2.
+
+1.  Changes to Bash
+
+a.  Only Posix-mode shells should exit on an assignment failure in the
+    temporary environment preceding a special builtin.  This is how it's been
+    documented.
+
+b.  Fixed a bug that caused a failed special builtin to not exit a posix-mode
+    shell if the failing builtin was on the LHS of a && or ||.
+
+c.  Changed the handling of unquoted backslashes in regular expressions to be
+    closer to bash-4.2.
+
+d.  globstar (**) no longer traverses symbolic links that resolve to
+    directories.  This eliminates some duplicate entries.
+
+e.  Fixed a bug that caused a SIGCHLD trap handler to not be able to change the
+    SIGCHLD disposition.
+
+f.  Fixed a bug that caused a crash when -x was enabled and a command
+    contained a printable multibyte (wide) character.
+
+g.  Fixed a bug that caused an interactive shell without line editing enabled
+    to read invalid data after receiving a SIGINT.
+
+h.  Fixed a bug that caused command word completion to fail if the directory in
+    $PATH where the completion would be found contained single or double quotes.
+
+i.  Fixed a bug that caused a shell with -v enabled to print commands in $()
+    multiple times.
+
+2.  Changes to Readline
+
+a.  Fixed a bug that caused `undo' to reference freed memory or null pointers.
+
+3.  New Features in Bash
+
+a.  The [[ -v ]] option now understands array references (foo[1]) and returns
+    success if the referenced element has a value.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.3-rc2, and the
+previous version, bash-4.3-rc1.

+d. Fixed a bug that caused asynchronous commands to not set $? correctly.
+
+e. Fixed a bug that caused out-of-order execution when executing aliases with
+   embedded newlines containing `.' commands.
+
+f. Fixed a bug that caused error messages generated by expansion errors in
+   `for' commands to have the wrong line number.
+
+g. Fixed a bug that caused the `wait' builtin to not be interruptible in an
+   interactive shell with job control enabled.
+
+h. Fixed a bug that caused SIGINT and SIGQUIT to not be trappable in
+   asynchronous subshell commands.
+
+i. Bash now requires that the value assigned to a nameref variable be a valid
+   shell identifier (variable name or array reference).
+
+j. Converting an existing variable to a nameref variable now turns off the
+   -i/-l/-u/-c attributes.
+
+k. Displaying a nameref variable with `declare -p' now displays the nameref
+   variable and its value rather than following the nameref chain.
+
+l. Fixed a problem with interrupt handling that caused a second and subsequent
+   SIGINT to be ignored by interactive shells.
+
+m. Fixed a bug that caused certain positional parameter and array expansions
+   to mishandle (discard) null positional parameters and array elements.
+
+n. The shell no longer blocks receipt of signals while running trap handlers
+   for those signals, and allows most trap handlers to be run recursively
+   (running trap handlers while a trap handler is executing).
+
+o. The shell now handles backslashes in regular expression arguments to the
+   [[ command's =~ operator slightly differently, resulting in more
+   consistent behavior.
+
+2.  Changes to Readline
+
+a. Fixed a bug that could cause readline to crash and seg fault attempting to
+   expand an empty history entry.
+
+b. Fixed a bug that caused a bad entry in the $LS_COLORS variable to abort all
+   color processing but leave color enabled.
+
+c. Fixed a bug that caused display problems with multi-line prompts containing
+   invisible characters on multiple lines.
+
+d. Fixed a bug that caused effects made by undoing changes to a history line to
+   be discarded.

+3.  New Features in Bash
+
+4.  New Features in Readline
+
+a.  When creating shared libraries on Mac OS X, the pathname written into the
+    library (install_name) no longer includes the minor version number.

+previous version, bash-4.3-beta2.
+
+1.  Changes to Bash
+
+a. Fixed a bug in bash completion that caused a tilde to be expanded even if
+   the `direxpand' option was not enabled.
+
+b. Fixed a potential bug that could cause corrupted input in interactive shells
+   running without line editing and with `ignoreeof' enabled.
+
+c. Fixed a bug that could cause failures when opening pipes back to shells
+   created to run process substitutions.
+
+d. Fixed a bug that caused an assignment to TEXTDOMAIN to require TEXTDOMAINDIR
+   to be set in order to actually change the current text domain.
+
+e. Changed the way redirections are printed to avoid confusion when the target
+   of an output redirection is a process substitution beginning with `>'.
+
+2.  Changes to Readline
+
+a. Shared library building is now supported on Mac OS X 10.9 (Darwin 13).
+
+3.  New Features in Bash
+
+a. `cd' has a new `-@' option to browse a file's extended attributes on
+   systems that support O_XATTR.
+
+4.  New Features in Readline
+
+a. There are additional default key bindings for MinGW32
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.3-beta2, and the
+previous version, bash-4.3-beta.
+
+1.  Changes to Bash
+
+a.  Fixed a bug that caused assignment to an unset variable using a negative
+    subscript to result in a segmentation fault.
+
+b.  Fixed a bug that caused assignment to a string variable using a negative
+    subscript to use the incorrect index.
+
+c.  Fixed a bug that caused some strings to be interpreted as invalid
+    extended globbing expressions when used with the help builtin.
+
+d.  Fixed a bug that caused an attempt to trap a signal whose disposition
+    cannot be changed to reference uninitialized memory.
+
+e.  Command completion now skips assignment statements preceding a command
+    name and completes the command.
+
+f.  Fixed a bug that caused `compgen -f' in a non-interactive shell to dump
+    core under certain circumstances.
+
+g.  Fixed a bug that caused the `read -N' to misbehave when the input stream
+    contains 0xff.
+
+2.  Changes to Readline
+
+a.  Changed message when an incremental search fails to include "failed" in
+    the prompt and display the entire search string instead of just the last
+    matching portion.
+
+b.  Fixed a bug that caused an arrow key typed to an incremental search prompt
+    to process the key sequence incorrectly.
+
+c.  Additional key bindings for arrow keys on MinGW.
+
+3.  New Features in Bash
+
+a.  The help builtin now attempts substring matching (as it did through
+    bash-4.2) if exact string matching fails.
+
+b.  The fc builtin now interprets -0 as the current command line.
+
+c.  Completing directory names containing shell variables now adds a trailing
+    slash if the expanded result is a directory.
+
+4.  New Features in Readline
+
+a.  rl_change_environment: new application-settable variable that controls
+    whether or not Readline modifies the environment (currently readline
+    modifies only LINES and COLUMNS).
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.3-beta, and the
+previous version, bash-4.3-alpha.
+
+1.  Changes to Bash
+
+a.  Fixed a bug in the prompt directory name "trimming" code that caused
+    memory corruption and garbled the results.
+
+b.  Fixed a bug that caused single quotes that resulted from $'...' quoting
+    in the replacement portion of a double-quoted ${word/pat/rep} expansion
+    to be treated as quote characters.
+
+c.  Fixed a bug that caused assignment statements preceding a command word to
+    result in assignment statements following a declaration command to not be
+    expanded like assignment statements.
+
+d.  Fixed a bug with variable search order in the presence of local variables
+    with the same name as variables in the temporary environment supplied to
+    a shell function.
+
+e.  Fixed a bug that caused constructs like 1<(2) to be interpreted as process
+    substitutions even in an arithmetic context.
+
+f.  Fixed several cases where `invisible' variables (variables with attributes
+    but no values, which are technically unset) were treated incorrectly.
+
+g.  Fixed a bug that caused group commands in pipelines that were not the
+    last element to not run the EXIT trap.
+
+h.  Fixed a bug that caused `unset -n' to not unset a nameref variable in
+    certain cases.
+
+i.  Fixed the nameref circular reference checking to be less strict and only
+    disallow a nameref variable with the same value as its name at the global
+    scope.
+
+j.  Fixed a bug that caused trap handlers to be executed recursively,
+    corrupting internal data structures.
+
+k.  Fixed a bug that could result in bash not compiling if certain options were
+    not enabled.
+
+l.  Fixed a bug that caused the arithmetic expansion code to attempt variable
+    assignments when operator precedence prohibited them.
+
+m.  Word expansions like ${foo##bar} now understand indirect variable references.
+
+n.  Fixed a bug that caused `declare -fp name' to not display a function 
+    definition.
+
+o.  Fixed a bug that caused asynchronous child processes to modify the stdin
+    file pointer when bash was using it to read a script, which modified the
+    parent's value as well.
+
+2.  Changes to Readline
+
+a.  Fixed a bug in vi mode that caused the arrow keys to set the saved last
+    vi-mode command to the wrong value.
+

+    waiting for a child process to exit.
+
+g.  Bash doesn't try to run things in a signal handler context when it gets a

+    process substitutions containing comments and quoted strings.
+
+t.  Fixed a problem with the bash malloc's internal idea of the top of the
+    memory heap that resulted in incorrect decisions to try to reduce the
+    break and give memory back to the kernel.
+
+u.  There are changes to the expansions performed on compound array assignments,
+    in an effort to make foo=( [ind1]=bar [ind2]=baz ) identical to
+    foo[ind1]=bar foo[ind2]=baz.
+
+v.  Bash now reports an error if `read -a name' is used when `name' is an

+
+z.  Fixed several bugs with the built-in snprintf replacement and field widths
+    and floating point.
+
+aa. Fixed a bug that caused incorrect offset calculations and input buffer

+
+bb. Fixed several bugs where bash performed arithmetic evaluation in contexts
+    where evaluation is suppressed.
+
+cc. Fixed a bug that caused bash to close FIFOs used for process substitution
+    too early when a shell function was executing, but protect against using
+    all file descriptors when the shell functions are invoked inside loops.
+
+dd. Added checks for printable (and non-printable) multibyte characters for
+    use in error messages.
+
+ee. Fixed a bug that caused ^O (operate-and-get-next) to not work correctly
+    at the end of the history list.
+
+ff. Fixed a bug that caused command-oriented history to incorrectly combine
+    here documents into one line.
+
+gg. Fixed a bug that caused importing SHELLOPTS from the environment into a
+    Posix-mode shell to print an error message and refuse to parse it.
+
+hh. Fixed a bug that caused the shell to delete an extra history entry when
+    using `history -s'.
+
+ii. Fixed a bug that caused floating-point exceptions and overflow errors
+    for the / and % arithmetic operators when using INTMAX_MIN and -1.
+
+jj. Fixed a bug that caused parsing errors when reading an arithmetic for
+    loop inside a command substitution.
+
+kk. Fixed a bug that caused a readonly function to be unset when unset was
+    called without the -f or -v option.
+
+ll. Fixed several bugs in the code that quotes characters special to regular
+    expressions when used in a quoted string on the RHS of the =~ operator
+    to the [[ command.
+
+mm. Fixed a bug that caused redirections to fail because the file descriptor
+    limit was set to a value less than 10.
+
+nn. Fixed a bug that caused the `read' builtin to execute code in a signal
+    handler context if read timed out.
+
+oo. Fixed a bug that caused extended globbing patterns to not match files
+    beginning with `.' correctly when a `.' was explicitly supplied in the
+    pattern.
+
+pp. Fixed a bug that caused key sequences longer than two characters to not
+    work when used with `bind -x'.
+
+qq. Fixed a bug that resulted in redefined functions having the wrong source
+    file names in BASH_SOURCE.
+
+rr. Fixed a bug that caused the read builtin to assign null strings to variables
+    when using `read -N', which caused core dumps when referenced
+
+ss. Fixed a bug that caused `bash -m script' to not enable job control while
+    running the script.
+
+tt. Fixed a bug that caused `printf -v var' to dump core when used with the

+
+uu. Fixed a bug that caused the shell to exit with the wrong status if -e was
+    active and the shell exited on a substitution error.
+
+vv. Fixed a bug that caused the shell to seg fault if an array variable with
+    the same name as an existing associative array was implicitly created by
+    an assignment (declare a[n]=b).
+
+ww. Fixed a bug that caused a redirection to misbehave if the number specified
+    for a file descriptor overflows an intmax_t.
+
+xx. Fixed several bugs with the handling of valid and invalid unicode character
+    values when used with the \u and \U escape sequences to printf and $'...'.
+
+yy. Fixed a bug that caused tildes to not be escaped in expanded filenames,
+    making them subject to later expansion.
+
+zz. When using the pattern substitution word expansion, bash now runs the
+    replacement string through quote removal, since it allows quotes in that
+    string to act as escape characters.  This is not backwards compatible, so
+    it can be disabled by setting the bash compatibility mode to 4.2.
+
+aaa. Fixed the rest of the cases where the shell runs non-allowed code in a
+     signal handler context.
+
+bbb. Fixed a bug that caused spurious DEL characters (\177) to appear in
+     double-quoted expansion where the RHS is evaluated to the empty string.
+
+ccc. Fixed a bug that caused the use of the shell's internal random number
+     generator for temporary file names to perturb the random number
+     sequence.
+
+ddd. Fixed several bugs that caused `declare -g' to not set the right global
+     variables or to misbehave when declaring global indexed arrays.
+
+eee. Fixed a logic bug that caused extended globbing in a multibyte locale to
+     cause failures when using the pattern substititution word expansions.
+
+fff. Fixed a bug that caused the `lastpipe' option to corrupt the file
+     descriptor used to read the script.
+
+ggg. Fixed a bug that causes the shell to delete DEL characters in the
+     expanded value of variables used in the same quoted string as variables
+     that expand to nothing.
+
+hhh. Fixed a bug that caused the shell to assign the wrong value from an
+     assignment like (( x=7 )) when `x' was an existing array variable.
+
+iii. Fixed a bug that caused the shell to misbehave when generating sequences
+     and the boundary values overflow an intmax_t.
+
+jjj. Fixed a bug caused expansion errors if an expansion of "$@" appeared
+     next to another expansion (e.g.. "${@}${x}").
+
+kkk. Fixed a potential buffer overflow bug when performing /dev/fd expansion.
+
+lll. Fixed a bug that resulted in an extra semicolon being added to compound
+     assignments when they were added to the history list.
+
+mmm. Fixed a bug that caused mapfile to read one extra line from the input.
+
+nnn. Fixed a bug that caused the mail checking code to use uninitialized
+     values.
+
+ooo. Fixed a bug that prevented history timestamps from being saved if the
+     history comment character is unset.
+
+ppp. Fixed a bug that caused the case-modifying expansions to not work with
+     multibyte characters.
+
+qqq. Fixed a bug that caused the edit-and-execute bindable readline command
+     to see the wrong data if invoked in the middle of a multi-line quoted
+     string.
+
+rrr. Fixed a bug that resulted in the shell returning the wrong exit status
+     for a background command on systems that recycle PIDs very quickly.
+
+sss. Fixed a bug that caused asynchronous group commands to not run any EXIT
+     trap defined in the body of the command.
+
+ttt. Fixed a bug that caused `eval "... ; return"' to not clean up properly.
+
+uuu. Fixed a bug that caused the shell to dump core if `read' reads an escaped
+     IFS whitespace character.
+
+vvv. Fixed a bug that caused BASH_COMMAND to be set to an incorrect value when
+     executing a (...) subshell.
+
+www. Fixed a couple of pointer aliasing bugs with the token string in arithmetic
+     evaluation.
+
+xxx. Fixed a bug with parsing multi-line command substitutions when reading
+     the `do' keyword followed by whitespace.
+
+yyy. Fixed a bug that caused the shell to seg fault if the time given to the
+     printf %(...)T format overflowed the value accepted by localtime(3).
+
+zzz. Fixed a problem with displaying help topics in two columns when the
+     translated text contained multibyte characters.
+
+aaaa. Fixed a bug with the extended globbing pattern matcher where a `*' was
+      followed by a negated extended glob pattern.
+
+bbbb. Fixed a race condition with short-lived coproc creation and reaping that
+      caused the child process to be reaped before the various coproc shell
+      variables were initialized.
+
+cccc. Fixed a bug where turning off `errexit' in command substitution subshells
+      was not reflected in $SHELLOPTS.
+
+dddd. Partially fixed an inconsistency in how the shell treated shell
+      functions run from an EXIT trap.
+
+eeee. Fixed a bug in how the shell invalidated FIFOs used for process
+      substitution when executing a pipeline (once rather than in every child).
+
+ffff. Fixed a bug that occurred when expanding a special variable ($@, $*)
+      within double quotes and the expansion resulted in an empty string.
+
+gggg. Fixed bugs with executing a SIGCHLD trap handler to make sure that it's
+      executed once per exited child.
+
+hhhh. Fixed a bug that caused `declare' and `test' to find variables that
+      had been given attributes but not assigned values.  Such variables are
+      not set.
+
+iiii. Fixed a bug that caused commands in process substitutions to not look in
+      the local temporary environment when performing word expansions.
+
+jjjj. Fixed several problems with globstar expansions (**/**) returning null
+      filenames and multiple instances of the same pathname.
+
+kkkk. Fixed an oversight that did not allow the exit status of `coproc' to
+      be inverted using `!'.
+
+llll. Fixed a bug that caused the -e option to be re-enabled using `set -e'
+      even when executing in a context where -e is ignored.
+
+mmmm. Fixed a (mostly theoretical) bug with input lines longer than SIZE_MAX.
+
+nnnn. Fixed a bug that could result in double evaluation of command
+      substitutions when they appear in failed redirections.
+
+oooo. Fixed a bug that could cause seg faults during `mapfile' callbacks if
+      the callback unsets the array variable mapfile is using.
+
+pppp. Fixed several problems with variable assignments using ${var:=value}
+      when the variable assignment is supposed to have side effects.
+
+qqqq. Fixed a bug that caused a failure of an assignment statement preceding a
+      builtin caused the next invocation of a special builtin to exit the shell.
+
+rrrr. Fixed several problems with IFS when it appears in the temporary environment
+      and is used in redirections.
+
+ssss. Fixed a problem that caused IFS changes using ${IFS:=value} to modify
+      how preceding expansions were split.
+
+tttt. Fixed a problem that caused subshells to not run an EXIT trap they set.
+
+uuuu. Fixed a problem that caused shells started in posix mode to attempt to
+      import shell functions with invalid names from the environment.  We now
+      print a warning.
+
+vvvv. Worked around a kernel problem that caused SIGCHLD to interrupt open(2)
+      on a FIFO used for process substitution, even if the SIGCHLD handler was
+      installed with the SA_RESTART flag.
+
+wwww. Fixed a problem that resulted in inconsistent expansion of $* and ${a[*]}.
+
+xxxx. Fixed a problem that caused `read -t' to crash when interrupted by
+      SIGINT.
+
+yyyy. Fixed a problem that caused pattern removal to fail randomly because the
+      pattern matcher read beyond the end of a string.
+
+zzzz. Fixed a bug that caused core dumps when shell functions tried to create
+      local shadow copies of special variables like GROUPS.
+
+aaaaa. Fixed a bug that caused SIGTERM to be occasionally lost by children of
+       interactive shells when it arrived before the child process reset the
+       handler from SIG_DFL.
+
+bbbbb. Fixed a bug that caused redirections like <&n- to leave file descriptor
+       n closed if executed with a builtin command.
+
+ccccc. Fixed a bug that caused incorrect completion quoting when completing a
+       word containing a globbing character with `show-all-if-ambiguous' set.
+
+ddddd. Fixed a bug that caused printf's %q format specifier not to quote a
+       tilde even if it appeared in a location where it would be subject to
+       tilde expansion.
+
+2.  Changes to Readline
+
+a.  Fixed a bug that did not allow the `dd', `cc', or `yy' vi editing mode
+    commands to work on the entire line.
+
+b.  Fixed a bug that caused redisplay problems with prompts longer than 128
+    characters and history searches.
+
+c.  Fixed a bug that caused readline to try and run code to modify its idea
+    of the screen size in a signal handler context upon receiving a SIGWINCH.
+
+d.  Fixed a bug that caused the `meta' key to be enabled beyond the duration
+    of an individual call top readline().
+    
+e.  Added a workaround for a wcwidth bug in Mac OS X that caused readline's
+    redisplay to mishandle zero-width combining characters.
+
+f.  Fixed a bug that caused readline to `forget' part of a key sequence when
+    a multiple-key sequence caused it to break out of an incremental search.
+
+g.  Fixed bugs that caused readline to execute code in a signal handler
+    context if interrupted while reading from the file system during completion.
+
+h.  Fixed a bug that caused readline to `forget' part of a key sequence when
+    reading an unbound multi-character key sequence.
+
+i.  Fixed a bug that caused Readline's signal handlers to be installed beyond
+    the bounds of a single call to readline().
+
+j.  Fixed a bug that caused the `.' command to not redo the most recent `R'
+    command in vi mode.
+
+k.  Fixed a bug that caused ignoring case in completion matches to result in
+    readline using the wrong match.
+
+l.  Paren matching now works in vi insert mode.
+
+m.  Fix menu-completion to make show-all-if-ambiguous and menu-complete-display-prefix
+    work together.
+
+n.  Fixed a bug that didn't allow the `cc', `dd', or `yy' commands to be redone
+    in vi editing mode.
+
+o.  Fixed a bug that caused the filename comparison code to not compare
+    multibyte characters correctly when using case-sensitive or case-mapping
+    comparisons.
+
+p.  Fixed the input reading loop to call the input hook function only when there
+    is no terminal input available.
+
+q.  Fixed a bug that caused binding a macro to a multi-character key sequence
+    where the sequence and macro value share a common prefix to not perform
+    the macro replacement.
+
+r.  Fixed several redisplay errors with multibyte characters and prompts
+    containing invisible characters when using horizontal scrolling.
+
+s.  Fixed a bug that caused redisplay errors when trying to overwrite
+    existing characters using multibyte characters.
+
+3.  New Features in Bash
+
+a.  The `helptopic' completion action now maps to all the help topics, not just
+    the shell builtins.
+
+b.  The `help' builtin no longer does prefix substring matching, so `help read'
+    does not match `readonly'.
+
+c.  The shell can be compiled to not display a message about processes that
+    terminate due to SIGTERM.
+
+d.  Non-interactive shells now react to the setting of checkwinsize and set
+    LINES and COLUMNS after a foreground job exits.
+
+e.  There is a new shell option, `globasciiranges', which, when set to on,
+    forces globbing range comparisons to use character ordering as if they
+    were run in the C locale.
+
+f.  There is a new shell option, `direxpand', which makes filename completion
+    expand variables in directory names in the way bash-4.1 did.
+
+g.  In Posix mode, the `command' builtin does not change whether or not a
+    builtin it shadows is treated as an assignment builtin.
+
+h.  The `return' and `exit' builtins accept negative exit status arguments.
+
+i.  The word completion code checks whether or not a filename containing a
+    shell variable expands to a directory name and appends `/' to the word
+    as appropriate.  The same code expands shell variables in command names
+    when performing command completion.
+
+j.  In Posix mode, it is now an error to attempt to define a shell function
+    with the same name as a Posix special builtin.
+
+k.  When compiled for strict Posix conformance, history expansion is disabled
+    by default.
+
+l.  The history expansion character (!) does not cause history expansion when
+    followed by the closing quote in a double-quoted string.
+
+m.  `complete' and its siblings compgen/compopt now takes a new `-o noquote'
+    option to inhibit quoting of the completions.
+
+n.  Setting HISTSIZE to a value less than zero causes the history list to be
+    unlimited (setting it 0 zero disables the history list).
+
+o.  Setting HISTFILESIZE to a value less than zero causes the history file size
+    to be unlimited (setting it to 0 causes the history file to be truncated
+    to zero size).
+
+p.  The `read' builtin now skips NUL bytes in the input.
+
+q.  There is a new `bind -X' option to print all key sequences bound to Unix
+    commands.
+
+r.  When in Posix mode, `read' is interruptible by a trapped signal.  After
+    running the trap handler, read returns 128+signal and throws away any
+    partially-read input.
+
+s.  The command completion code skips whitespace and assignment statements
+    before looking for the command name word to be completed.
+
+t.  The build process has a new mechanism for constructing separate help files
+    that better reflects the current set of compilation options.
+
+u.  The -nt and -ot options to test now work with files with nanosecond
+    timestamp resolution.
+
+v.  The shell saves the command history in any shell for which history is
+    enabled and HISTFILE is set, not just interactive shells.
+
+w.  The shell has `nameref' variables and new -n(/+n) options to declare and
+    unset to use them, and a `test -R' option to test for them.
+
+x.  The shell now allows assigning, referencing, and unsetting elements of
+    indexed arrays using negative subscripts (a[-1]=2, echo ${a[-1]}) which
+    count back from the last element of the array.
+
+y.  The {x}<word redirection feature now allows words like {array[ind]} and
+    can use variables with special meanings to the shell (e.g., BASH_XTRACEFD).
+
+z.  There is a new CHILD_MAX special shell variable; its value controls the
+    number of exited child statuses the shell remembers.
+
+aa. There is a new configuration option (--enable-direxpand-default) that
+    causes the `direxpand' shell option to be enabled by default.
+
+bb. Bash does not do anything special to ensure that the file descriptor
+    assigned to X in {x}<foo remains open after the block containing it
+    completes.
+
+cc. The `wait' builtin has a new `-n' option to wait for the next child to
+    change status.
+
+dd. The `printf' %(...)T format specifier now uses the current time if no
+    argument is supplied.
+
+ee. There is a new variable, BASH_COMPAT, that controls the current shell
+    compatibility level.
+
+ff. The `popd' builtin now treats additional arguments as errors.
+
+gg. The brace expansion code now treats a failed sequence expansion as a
+    simple string and will continue to expand brace terms in the remainder
+    of the word.
+
+4.  New Features in Readline
+
+a.  Readline is now more responsive to SIGHUP and other fatal signals when
+    reading input from the terminal or performing word completion but no
+    longer attempts to run any not-allowable functions from a signal handler
+    context.
+
+b.  There are new bindable commands to search the history for the string of
+    characters between the beginning of the line and the point
+    (history-substring-search-forward, history-substring-search-backward)
+
+c.  Readline allows quoted strings as the values of variables when setting
+    them with `set'.  As a side effect, trailing spaces and tabs are ignored
+    when setting a string variable's value.
+
+d.  The history library creates a backup of the history file when writing it
+    and restores the backup on a write error.
+
+e.  New application-settable variable: rl_filename_stat_hook: a function called
+    with a filename before using it in a call to stat(2).  Bash uses it to
+    expand shell variables so things like $HOME/Downloads have a slash
+    appended.
+
+f.  New bindable function `print-last-kbd-macro', prints the most-recently-
+    defined keyboard macro in a reusable format.
+
+g.  New user-settable variable `colored-stats', enables use of colored text
+    to denote file types when displaying possible completions (colored analog
+    of visible-stats).
+
+h.  New user-settable variable `keyseq-timout', acts as an inter-character
+    timeout when reading input or incremental search strings.
+
+i.  New application-callable function: rl_clear_history. Clears the history list
+    and frees all readline-associated private data.
+
+j.  New user-settable variable, show-mode-in-prompt, adds a characters to the
+    beginning of the prompt indicating the current editing mode.
+
+k.  New application-settable variable: rl_input_available_hook; function to be
+    called when readline needs to check whether there is data available on its
+    input source.  The default hook checks rl_instream.
+
+l.  Readline calls an application-set event hook (rl_signal_event_hook) after
+    it gets a signal while reading input (read returns -1/EINTR but readline
+    does not handle the signal immediately) to allow the application to handle
+    or otherwise note it.  Not currently called for SIGHUP or SIGTERM.
+
+m.  If the user-settable variable `history-size' is set to a value less than
+    0, the history list size is unlimited.

+and the previous version, bash-4.2-rc1.
+
+1.  Changes to Bash
+
+a.  Changes to bash_directory_completion_hook so that it's assigned to the
+    readline rl_directory_rewrite_hook variable, which modifies the directory
+    name passed to opendir without modifying the directory name the user
+    typed.
+
+b.  Fixed bug in select builtin that caused it to not terminate correctly if
+    the read timed out due to $TMOUT.
+
+c.  Fixed a problem that resulted in non-repeatable sequences of random
+    numbers when RANDOM=0.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.2-rc1,
+and the previous version, bash-4.2-beta.
+
+1.  Changes to Bash
+
+a.  Fixed a bug that caused some redirection errors to leak file descriptors.
+
+b.  Fixed a bug that caused unary `+' and `-' arithmetic operators to have a
+    higher precedence than unary `!' and `~'.
+
+c.  Fixed a bug that caused simple commands in a pipeline to affect the exit
+    status ($?) seen by subsequent pipeline commands.
+
+d.  A number of cygwin-specific changes to avoid the use of text-mode files
+    and file access, and to make sure that \r is handled correctly.
+
+e.  Fixed a bug that caused the read builtin to not return failure if an
+    attempt is made to assign to a readonly variable.
+
+f.  Fixed a bug that caused some builtin usage messages to not be translated.
+
+g.  Fixed a bug that caused the getopts builtin to not return failure if an
+    attempt is made to assign to a readonly variable.  Now it returns 2.
+
+h.  Fixed the cd and pwd builtins to return failure if PWD is readonly and
+    cannot be assigned to.
+
+i.  Added code to check the return value of access(2) on Solaris systems,
+    since it returns success for executable tests (e.g., `test -x') when
+    run by root, even if the file permissions don't allow execution.
+
+2.  Changes to Readline
+
+a.  Fixed a bug that caused directory names in words to be completed to not
+    be dequoted correctly.
+
+3.  New Features in Bash
+
+4.  New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.2-beta,
+and the previous version, bash-4.2-alpha.
+
+1.  Changes to Bash
+
+a.  Fixed a bug that caused the \W prompt string escape to not add a closing
+    NULL.
+
+b.  Fixed a bug that caused partially-quoted words that were not subject to
+    word splitting to retained quoted NULLs.
+
+c.  Added considerable efficiency speedups when pattern matching in multibyte
+    locales by skipping multibyte character functions where possible.
+
+d.  Added considerable speedups to variable expansion when in multibyte locales.
+
+e.  Fixed a bug that caused the expansion of $* when there are no positional
+    parameters to cause the shell to dump core when used in a pattern
+    matching context.
+
+f.  Fixed a bug that caused variable expansions preceding regular builtins to
+    not change the shell environment during their execution.
+
+2.  Changes to Readline
+
+a.  Fixed a bug that made an explicit argument of 0 to yank-last-arg behave
+    as if it were a negative argument.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.2-alpha,
+and the previous version, bash-4.1-release.
+
+1.  Changes to Bash
+
+a.  Fixed a bug in the parser when processing alias expansions containing
+    quoted newlines.
+
+b.  Fixed a memory leak in associative array expansion.
+
+c.  Fixed a bug that caused quoted here-strings to be requoted when printed.
+
+d.  Fixed a bug in arithmetic expansion that caused the index in an array
+    expansion to be evaluated twice under certain circumstances.
+
+e.  Fixed several bugs with the expansion and display of variables that have
+    been given attributes but not values and are technically unset.
+
+f.  Fixed a bug that caused core dumps when using filename completion that
+    expands to a filename containing a globbing character.
+
+g.  Fixed a bug that caused assignment statements preceding a special builtin
+    when running in Posix mode to not persist after the builtin completed
+    when the special builtin was executed in a shell function without any
+    local variables.
+
+h.  Fixed a bug that caused a command to remain in the hash table even after
+    `hash command' did not find anything if there was already an existing
+    hashed pathname.
+
+i.  Fixed several bugs caused by executing unsafe functions from a signal
+    handler in the cases where a signal handler is executed immediately
+    rather than setting a flag for later execution.
+
+j.  Fixed a bug that caused some internal flag variables to be set
+    incorrectly if `read -t' timed out.
+
+k.  Fixed a Posix compatibility issue by making sure that a backslash escaping
+    a `}' within a double-quoted ${...} parameter expansion is removed as part
+    of the parameter expansion.
+
+l.  Fixed a bug that caused execution of a trap to overwrite PIPESTATUS.
+
+m.  Fixed a bug that caused here documents to not be displayed correctly
+    when attached to commands inside compound commands.
+
+n.  Fixed a bug that caused the printf builtin to use the wrong precision
+    when using the `*' modifier.
+
+o.  Fixed a bug that caused an arriving SIGCHLD to interrupt output functions
+    like those invoked by echo or printf.
+
+p.  Changed to use a more robust mechanism than eaccess(2) when test is
+    checking filenames for execution permission.
+
+q.  Fixed a bug that caused spurious semicolons to be added into the command
+    history in certain cases.
+
+r.  Fixed a bug that caused the shell to free non-allocated memory when
+    unsetting element 0 of an associative array after it was assigned
+    implicitly.
+
+s.  Fixed a bug that could cause the shell to dump core if using the `v'
+    vi editing command on a multi-line command.
+
+t.  Fixed a bug that left FIFOs opened by process substitutions open long
+    enough to potentially cause file descriptor exhaustion when running a
+    shell function or shell builtin.
+
+u.  Fixed a bug that caused the history expansion functions to not recognize
+    process substitution or extended glob patterns as single words.
+
+v.  Fixed a bug that caused restricted shells to set a restricted command's
+    exit status incorrectly.
+
+w.  Fixed a bug that caused bash to ignore the wrong set of filenames when
+    completing a command using the `complete-filename' readline command.
+
+x.  Fixed a bug that caused a -PID argument following a -s sig or -n sig to
+    not be interpreted as a signal specification.
+
+y.  Changed posix-mode behavior of a parse error in a `.' script or `eval'
+    command to exit the shell under Posix-specified conditions.  Previous
+    versions printed a warning.
+
+z.  Fixed a bug in \W prompt expansion that resulted in incorrect expansion
+    in the event of overlapping strings.
+
+aa. Fixed a bug that caused the := parameter expansion operator to return the
+    wrong value as the result of the expansion.
+
+bb. When in Posix mode, a single quote is not treated specially in a
+    double-quoted ${...} expansion, unless the expansion operator is
+    # or % or the non-Posix `//', `^', and `,'.  In particular, it does
+    not define a new quoting context.  This is from Posix interpretation 221.
+
+cc. Fixed a bug that inadvertently allowed program names containing slashes
+    to be entered into the command hash table.
+
+dd. Fixed a bug that caused the select builtin to incorrectly compute the
+    display width of the arguments in the presence of multibyte characters.
+
+ee. Fixed a bug that caused bash to not change the xtrace file descriptor if
+    BASH_XTRACEFD was found in the shell environment at startup.
+
+ff. Fixed a memory leak in the pattern removal parameter expansion.
+
+gg. Fixed a bug that caused SIGINT to fail to interrupt a nested loop if the
+    loop was in a pipeline.
+
+hh. Fixed a problem in $(...) parsing that caused the parser to add an extra
+    space to a here-document delimiter if the first word contained a `/'.
+
+ii. Fixed a bug that caused functions defined with the `function' reserved
+    word to require braces around the function body.
+
+jj. Fixed a bug that caused bash to dump core when a variable expansion being
+    used as an array subscript failed.
+
+kk. Fixed a bug that caused bash to dump core if the case-modification
+    expansions were used on a variable with a null value.
+
+ll. Fixed a bug that caused partially-quoted strings to be split incorrectly
+    if a variable with a null value was expanded within double quotes.
+
+mm. The pattern substitution word expansion has been sped up dramatically
+    when running in a locale with multibyte characters.
+
+nn. Fixed a bug that caused history -a to not write the correct lines to
+    the history file if all the new lines in the history list were added
+    since the last time the history file was read or written.
+
+oo. Fixed a bug that caused completion of a word with an unclosed `` command
+    substitution to set the prompt incorrectly.
+
+pp. Fixed a bug that caused extended globbing patterns in $HISTIGNORE or
+    $GLOBIGNORE to be incorrectly scanned.
+
+qq. Fixed a bug caused by closing file descriptors 3-20 on shell startup.  The
+    shell now sets them to close-on-exec.
+
+rr. Fixed a bug that caused the exit status of `exec file' to be set incorrectly
+    if `file' was a directory.
+
+ss. Fixed a bug in the `.' builtin to make a non-interactive posix-mode shell
+    exit if the file argument to `.' is not found.  Prefixing exec with 
+    `command' makes the shell not exit. Posix requires this behavior.
+
+tt. Fixed a bug that caused `sh -c 'command exec; exit 1' to hang.
+
+uu. Fixed a bug in $(...) command substitution parsing that caused the shell
+    to treat backslash-newline incorrectly when parsing a comment.
+
+vv. Fixed bug that caused brace expansion sequence generation to misbehave
+    when supplied integers greater than 2**31 - 1.
+
+ww. Fixed a bug that caused failure to save file descriptors for redirections
+    to corrupt shell file descriptors.
+
+xx. Fixed a bug that caused bash-forward-shellword to not correctly handle
+    quoted strings.
+
+2.  Changes to Readline
+
+a.  Fixed a bug that caused the unconverted filename to be added to the list of
+    completions when the application specified filename conversion functions.
+
+b.  Fixed a bug that caused the wrong filename to be passed to opendir when the
+    application has specified a filename dequoting function.
+
+c.  Fixed a bug when repeating a character search in vi mode in the case where
+    there was no search to repeat.
+
+d.  When show-all-if-ambiguous is set, the completion routines no longer insert
+    a common match prefix that is shorter than the text being completed.
+
+e.  The full set of vi editing commands may now be used in callback mode.
+
+f.  Fixed a bug that caused readline to not update its idea of the terminal
+    dimensions while running in `no-echo' mode.
+
+h.  Fixed a bug that caused readline to dump core if an application called
+    rl_prep_terminal without setting rl_instream.
+
+i.  Fixed a bug that caused meta-prefixed characters bound to incremental
+    search forward or backward to not be recognized if they were typed
+    subsequently.
+
+j.  The incremental search code treats key sequences that map to the same
+    functions as (default) ^G, ^W, and ^Y as equivalent to those characters.
+
+k.  Fixed a bug in menu-complete that caused it to misbehave with large
+    negative argument.
+
+l.  Fixed a bug that caused vi-mode yank-last-arg to ring the bell when invoked
+    at the end of the line.
+
+3.  New Features in Bash
+
+a.  `exec -a foo' now sets $0 to `foo' in an executable shell script without a
+    leading #!.
+
+b.  Subshells begun to execute command substitutions or run shell functions or
+    builtins in subshells do not reset trap strings until a new trap is
+    specified.  This allows $(trap) to display the caller's traps and the
+    trap strings to persist until a new trap is set.
+
+c.  `trap -p' will now show signals ignored at shell startup, though their
+    disposition still cannot be modified.
+
+d.  $'...', echo, and printf understand \uXXXX and \UXXXXXXXX escape sequences.
+
+e.  declare/typeset has a new `-g' option, which creates variables in the
+    global scope even when run in a shell function.
+
+f.  test/[/[[ have a new -v variable unary operator, which returns success if
+    `variable' has been set.
+
+g.  Posix parsing changes to allow `! time command' and multiple consecutive
+    instances of `!' (which toggle) and `time' (which have no cumulative
+    effect).
+
+h.  Posix change to allow `time' as a command by itself to print the elapsed
+    user, system, and real times for the shell and its children.
+
+j.  $((...)) is always parsed as an arithmetic expansion first, instead of as
+    a potential nested command substitution, as Posix requires.
+
+k.  A new FUNCNEST variable to allow the user to control the maximum shell
+    function nesting (recursive execution) level.
+
+l.  The mapfile builtin now supplies a third argument to the callback command:
+    the line about to be assigned to the supplied array index.
+
+m.  The printf builtin has a new %(fmt)T specifier, which allows time values
+    to use strftime-like formatting.
+
+n.  There is a new `compat41' shell option.
+
+o.  The cd builtin has a new Posix-mandated `-e' option.
+
+p.  Negative subscripts to indexed arrays, previously errors, now are treated
+    as offsets from the maximum assigned index + 1.
+
+q.  Negative length specifications in the ${var:offset:length} expansion,
+    previously errors, are now treated as offsets from the end of the variable.
+
+r.  Parsing change to allow `time -p --'.
+
+s.  Posix-mode parsing change to not recognize `time' as a keyword if the
+    following token begins with a `-'.  This means no more Posix-mode
+    `time -p'.  Posix interpretation 267.
+
+t.  There is a new `lastpipe' shell option that runs the last command of a
+    pipeline in the current shell context.  The lastpipe option has no
+    effect if job control is enabled.
+
+u.  History expansion no longer expands the `$!' variable expansion.
+
+v.  Posix mode shells no longer exit if a variable assignment error occurs
+    with an assignment preceding a command that is not a special builtin.
+
+w.  Non-interactive mode shells exit if -u is enabled and an attempt is made
+    to use an unset variable with the % or # expansions, the `//', `^', or
+    `,' expansions, or the parameter length expansion.
+
+x.  Posix-mode shells use the argument passed to `.' as-is if a $PATH search
+    fails, effectively searching the current directory.  Posix-2008 change.
+
+4.  New Features in Readline
+
+a.  The history library does not try to write the history filename in the
+    current directory if $HOME is unset.  This closes a potential security
+    problem if the application does not specify a history filename.
+
+b.  New bindable variable `completion-display-width' to set the number of
+    columns used when displaying completions.
+
+c.  New bindable variable `completion-case-map' to cause case-insensitive
+    completion to treat `-' and `_' as identical.
+
+d.  There are new bindable vi-mode command names to avoid readline's case-
+    insensitive matching not allowing them to be bound separately.
+
+e.  New bindable variable `menu-complete-display-prefix' causes the menu
+    completion code to display the common prefix of the possible completions
+    before cycling through the list, instead of after.
+

+b.  Fixed a bug that caused the shell to incorrectly split case patterns if
+    they contained characters in $IFS.
+
+c.  Fixed a bug that caused the shell to set $? to the wrong value when using
+    a construct ending with a variable assignment with set -x enabled and PS4
+    containing a command substitution.
+

+
+e.  Fixed a bug that caused the shell to set $? incorrectly if a parse error
+    occurred in an evaluation context ("eval", trap command, dot script, etc.)
+

+
+i.  Fixed a bug that caused bash to incorrectly report the presence of new

+
+j.  Fixed a bug that caused the shell to not recognize a here-document ending

+
+k.  Fixed a bug that caused the shell to crash when a a dynamic array variable
+    was assigned a scalar value.
+
+2.  Changes to Readline
+
+3.  New Features in Bash

+    callbacks in the history list.
+
+b.  There is a new `compat40' shopt option.

+    only if the compatibility level is greater than 40 (set to 41 by default).
+
+4.  New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.1-alpha,
+and the previous version, bash-4.0-release.
+
+1.  Changes to Bash
+
+a.  Fixed bugs in the parser involving new parsing of the commands contained

+
+b.  Fixed a bug that caused the shell to dump core when performing programmable
+    completion using a shell function.
+
+c.  Fixed a bug in `mapfile' that caused it to invoke callbacks at the wrong
+    time.

+
+e.  Fixed several bugs encountered when reading subscripts in associative
+    array assignments and expansions.
+
+f.  Fixed a bug that under some circumstances caused an associative array to
+    be converted to an indexed array.
+
+g.  Fixed a bug that caused syntax errors and SIGINT interrupts to not set
+    $? to a value > 128.
+
+h.  Fixed a bug that caused the shell to remove FIFOs associated with process
+    substitution inside shell functions.
+
+i.  Fixed a bug that caused terminal attributes to not be reset when the
+    `read' builtin timed out.
+
+j.  Fixed a bug in brace expansion that caused unwanted zero padding of the
+    expanded terms.
+
+k.  Fixed a bug that prevented the |& construct from working as intended when
+    used with a simple command with additional redirections.
+
+l.  Fixed a bug with the case statement ;& terminator that caused the shell to
+    dereference a NULL pointer.
+
+m.  Fixed a bug that caused assignment statements or redirections preceding
+    a simple command name to inhibit alias expansion.
+
+n.  Fixed the behavior of `set -u' to conform to the latest Posix interpretation:
+    every expansion of an unset variable except $@ and $* will cause the
+    shell to exit.
+
+o.  Fixed a bug that caused double-quoted expansions of $* inside word
+    expansions like ${x#$*} to not expand properly when $IFS is empty.
+
+p.  Fixed a bug that caused traps to set $LINENO to the wrong value when they
+    execute.
+
+q.  Fixed a bug that caused off-by-one errors when computing history lines in
+    the `fc' builtin.
+
+r.  Fixed a bug that caused some terminating signals to not exit the shell
+    quickly enough, forcing the kernel to send the signal (e.g., SIGSEGV)
+    multiple times.
+
+s.  Fixed a bug that caused the shell to attempt to add empty lines to the
+    history list when reading here documents.
+
+t.  Made some internal changes that dramatically speeds up sequential indexed
+    array access.
+
+u.  Fixed a bug that caused the shell to write past the end of a string when
+    completing a double-quoted string ending in a backslash.
+
+v.  Fixed a bug that caused the shell to replace too many characters when a
+    pattern match was null in a ${foo//bar} expansion.
+
+w.  Fixed bugs in the expansion of ** that caused duplicate directory names
+    and the contents of the current directory to be omitted.
+
+x.  Fixed a bug that caused $? to not be set correctly when referencing an
+    unset variable with set -u and set -e enabled.
+
+y.  Fixed a bug caused by executing an external program from the DEBUG trap
+    while a pipeline was running.  The effect was to disturb the pipeline
+    state, occasionally causing it to hang.
+
+z.  Fixed a bug that caused the ** glob expansion to dump core if it
+    encountered an unsearchable directory.
+
+aa. Fixed a bug that caused `command -v' and `command -V' to not honor the
+    path set by the -p option.
+
+bb. Fixed a bug that caused brace expansion to take place too soon in some
+    compound array assignments.
+
+cc. Fixed a bug that caused programmable completion functions' changes to
+    READLINE_POINT to not be reflected back to readline.
+
+dd. Fixed a bug that caused the shell to dump core if a trap was executed
+    during a shell assignment statement.
+
+ee. Fixed an off-by-one error when computing the number of positional
+    parameters for the ${@:0:n} expansion.
+
+ff. Fixed a problem with setting COMP_CWORD for programmable completion
+    functions that could leave it set to -1.
+
+gg. Fixed a bug that caused the ERR trap to be triggered in some cases where
+    `set -e' would not have caused the shell to exit.
+
+hh. Fixed a bug that caused changes made by `compopt' to not persist past the
+    completion function in which compopt was executed.
+
+ii. Fixed a bug that caused the list of hostname completions to not be cleared
+    when HOSTNAME was unset.
+
+jj. Fixed a bug that caused variable expansion in here documents to look in
+    any temporary environment.
+
+kk. Bash and readline can now convert file names between precomposed and
+    decomposed Unicode on Mac OS X ("keyboard" and file system forms,
+    respectively).  This affects filename completion (using new
+    rl_filename_rewrite_hook), globbing, and readline redisplay.
+
+ll. The ERR and EXIT traps now see a non-zero value for $? when a parser
+    error after set -e has been enabled causes the shell to exit.
+
+mm. Fixed a bug that in brace expansion that caused zero-prefixed terms to
+    not contain the correct number of digits.
+
+nn. Fixed a bug that caused the shell to free non-allocated memory when
+    unsetting an associative array which had had a value implicitly assigned
+    to index "0".
+
+oo. Fixed a memory leak in the ${!prefix@} expansion.
+
+pp. Fixed a bug that caused printf to not correctly report all write errors.
+
+qq. Fixed a bug that caused single and double quotes to act as delimiters
+    when splitting a command line into words for programmable completion.
+
+rr. Fixed a bug that caused ** globbing that caused **/path/* to match every
+    directory, not just those matching `path'.
+
+ss. Fixed a bug that caused the shell to dump core when running `help' without
+    arguments if the terminal width was fewer than 7 characters.
+
+2.  Changes to Readline
+
+a.  The SIGWINCH signal handler now avoids calling the redisplay code if
+    one arrives while in the middle of redisplay.
+
+b.  Changes to the timeout code to make sure that timeout values greater
+    than one second are handled better.
+
+c.  Fixed a bug in the redisplay code that was triggered by a prompt
+    containing invisible characters exactly the width of the screen.
+
+d.  Fixed a bug in the redisplay code encountered when running in horizontal
+    scroll mode.
+
+e.  Fixed a bug that prevented menu completion from properly completing
+    filenames.
+
+f.  Fixed a redisplay bug caused by a multibyte character causing a line to
+    wrap.
+
+g.  Fixed a bug that caused key sequences of two characters to not be
+    recognized when a longer sequence identical in the first two characters
+    was bound.
+
+h.  Fixed a bug that caused history expansion to be attempted on $'...'
+    single-quoted strings.
+
+i.  Fixed a bug that caused incorrect redisplay when the prompt contained
+    multibyte characters in an `invisible' sequence bracketed by \[ and
+    \].
+
+j.  Fixed a bug that caused history expansion to short-circuit after
+    encountering a multibyte character.
+
+3.  New Features in Bash
+
+a.  Here-documents within $(...) command substitutions may once more be
+    delimited by the closing right paren, instead of requiring a newline.
+
+b.  Bash's file status checks (executable, readable, etc.) now take file
+    system ACLs into account on file systems that support them.
+
+c.  Bash now passes environment variables with names that are not valid
+    shell variable names through into the environment passed to child
+    processes.
+
+d.  The `execute-unix-command' readline function now attempts to clear and
+    reuse the current line rather than move to a new one after the command
+    executes.
+
+e.  `printf -v' can now assign values to array indices.
+
+f.  New `complete -E' and `compopt -E' options that work on the "empty"
+    completion: completion attempted on an empty command line.
+
+g.  New complete/compgen/compopt -D option to define a `default' completion:
+    a completion to be invoked on command for which no completion has been
+    defined.  If this function returns 124, programmable completion is
+    attempted again, allowing a user to dynamically build a set of completions
+    as completion is attempted by having the default completion function
+    install individual completion functions each time it is invoked.
+
+h.  When displaying associative arrays, subscripts are now quoted.
+
+i.  Changes to dabbrev-expand to make it more `emacs-like': no space appended
+    after matches, completions are not sorted, and most recent history entries
+    are presented first.
+
+j.  The [[ and (( commands are now subject to the setting of `set -e' and the
+    ERR trap.
+
+k.  The source/. builtin now removes NUL bytes from the file before attempting
+    to parse commands.
+
+l.  There is a new configuration option (in config-top.h) that forces bash to
+    forward all history entries to syslog.
+
+m.  A new variable $BASHOPTS to export shell options settable using `shopt' to
+    child processes.
+
+n.  There is a new configure option that forces the extglob option to be
+    enabled by default.
+
+o.  New variable $BASH_XTRACEFD; when set to an integer bash will write xtrace
+    output to that file descriptor.
+
+p.  If the optional left-hand-side of a redirection is of the form {var}, the
+    shell assigns the file descriptor used to $var or uses $var as the file
+    descriptor to move or close, depending on the redirection operator.
+
+q.  The < and > operators to the [[ conditional command now do string
+    comparison according to the current locale.
+
+r.  Programmable completion now uses the completion for `b' instead of `a'
+    when completion is attempted on a line like: a $(b c.
+
+s.  Force extglob on temporarily when parsing the pattern argument to
+    the == and != operators to the [[ command, for compatibility.
+
+t.  Changed the behavior of interrupting the wait builtin when a SIGCHLD is
+    received and a trap on SIGCHLD is set to be Posix-mode only.
+
+u.  The read builtin has a new `-N nchars' option, which reads exactly NCHARS
+    characters, ignoring delimiters like newline.
+
+4.  New Features in Readline
+
+a.  New bindable function: menu-complete-backward.
+
+b.  In the vi insertion keymap, C-n is now bound to menu-complete by default,
+    and C-p to menu-complete-backward.
+
+c.  When in vi command mode, repeatedly hitting ESC now does nothing, even
+    when ESC introduces a bound key sequence.  This is closer to how
+    historical vi behaves.
+
+d.  New bindable function: skip-csi-sequence.  Can be used as a default to
+    consume key sequences generated by keys like Home and End without having
+    to bind all keys.
+
+e.  New application-settable function: rl_filename_rewrite_hook.  Can be used
+    to rewrite or modify filenames read from the file system before they are
+    compared to the word to be completed.
+
+f.  New bindable variable: skip-completed-text, active when completing in the
+    middle of a word.  If enabled, it means that characters in the completion
+    that match characters in the remainder of the word are "skipped" rather
+    than inserted into the line.
+
+g.  The pre-readline-6.0 version of menu completion is available as
+    "old-menu-complete" for users who do not like the readline-6.0 version.
+
+h.  New bindable variable: echo-control-characters.  If enabled, and the
+    tty ECHOCTL bit is set, controls the echoing of characters corresponding
+    to keyboard-generated signals.
+
+i.  New bindable variable: enable-meta-key.  Controls whether or not readline
+    sends the smm/rmm sequences if the terminal indicates it has a meta key
+    that enables eight-bit characters.

+
+ii. Fixed a bug when displaying a function due to not converting the function
+    to an external form.
+
+jj. Changed job control initialization to ensure that the shell has a tty

+ll. Fixed bug that could cause the shell to dump core in certain cases where
+    a command sets the SIGINT disposition to the default.
+
+mm. Fixed a bug in the pattern replacement (affecting both word expansion
+    and the `fc' builtin) that occurred when the pattern and replacement
+    strings were empty.
+
+nn. Fixed a bug that caused an arithmetic evaluation error to disable all

+
+tt. Fixed a problem in the printf builtin that resulted in single-byte
+    output for the "'" escape, even when using multibyte characters.
+
+uu. Fixed a bug that caused the failure exit status to be lost when redirections
+    attached to a compound command failed.
+
+vv. Fixed a bug that caused the internal random number generator to not be
+    re-seeded correctly when creating a subshell.
+
+ww. Fixed a bug that could cause the bash replacement getcwd to overwrite
+    memory.
+
+xx. Fixed a bug that caused the shell to not receive SIGINT if it was sent
+    while the shell was waiting for a command substitution to terminate, and
+    make sure the exit status is correct when it does.
+
+yy. Fixed a bug that resulted in the second and subsequent children spawned
+    by a shell begun to run a command substitution being placed into the
+    wrong process group.
+
+zz. Fixed a bug that caused the results of successful tilde expansion to be
+    subject to pathname expansion and word splitting.
+
+aaa. Fixed a bug that could cause the shell to hang if it encountered an
+     error that caused it to jump back to the top processing loop during a
+     command substitution or `eval' command.
+
+bbb. Fixed a bug that caused the `read' builtin to use the tty's attributes
+     instead of those of the file descriptor passed with the -u option when
+     processing the -n and -d options.
+
+ccc. Fixed a bug that caused incorrect expansion of ${array[@]:foo} if the
+     first character of $IFS was not whitespace.
+
+ddd. Fixed a bug that occurred when scanning for the ending delimiter of a
+     ${parameter/pat/sub} expansion.
+
+eee. Fixed a bug that caused the shell to inappropriately expand command
+     substitutions in words when expanding directory names for completion.

+     to persist in the shell environment.
+
+nnn. Fixed a bug that caused the terminal to be left in non-canonical mode
+     when using editing commands that invoke the an editor on the current
+     command line.
+
+ooo. Fixed a bug that caused globbing characters and characters in $IFS to not
+     be quoted appropriately when displaying assignment statements.
+
+ppp. Fixed a bug that caused the `-e' option to be inherited when sourcing a

+
+qqq. Fixed a bug that caused the shell to attempt to created variables with
+     invalid names if such names appeared in the initial environment.
+
+rrr. Fixed a bug with quote removal in strings where the final character is a
+     backslash.
+

+ttt. Fixed a bug that caused the history to not be saved after `history -c' or
+     `history -d' was executed until a sufficient number of commands had been
+     saved to the history.
+
+uuu. Bash now parses command substitutions according to Posix rules: parsing
+     the command contained in $() to find the closing delimiter.
+
+vvv. Fixed a bug that caused traps on SIGCHLD set in a SIGCHLD handler to
+     not persist.
+
+www. Fixed a bug that didn't allow SIGCHLD to interrupt the `wait' builtin
+     as Posix specifies.
+
+xxx. Invalid numeric arguments to shell builtins no longer cause the shell to
+     short-circuit any executing compound command.
+
+yyy. Fixed a bug that caused the exit status to be lost when `break' was
+     used to short-circuit a loop's execution.
+
+zzz. Fixed a bug that caused stray ^? characters to be left in expansions of
+     "${array[*]}".
+
+aaaa. Bash now prints better error messages for here documents terminated by
+      EOF and for identifying the incorrect token in an invalid arithmetic
+      expression.
+
+bbbb. Fixed a bug in the variable length word expansion that caused it to
+      incorrectly calculate the number of multibyte characters.
+
+cccc. Fixed a race condition that could result in the top-level shell setting
+      the terminal's process group to an incorrect value if the process
+      group was changed by a child of a child of the shell.
+
+dddd. Fixed a bug that caused here documents belonging to commands within a
+      compound command to be displayed in a syntactially-incorrect form, which
+      prevented them from being re-read as input.
+
+eeee. The shell displays more warnings about failures to set the locale.
+
+ffff. Fixed a bug that caused the body of a here-document to not be saved to
+      the history list.

+
+2.  Changes to Readline
+
+a.  Fixed a number of redisplay errors in environments supporting multibyte 
+    characters.
+
+b.  Fixed bugs in vi command mode that caused motion commands to inappropriately
+    set the mark.
+
+c.  When using the arrow keys in vi insertion mode, readline allows movement
+    beyond the current end of the line (unlike command mode).
+
+d.  Fixed bugs that caused readline to loop when the terminal has been taken
+    away and reads return -1/EIO.
+
+e.  Fixed bugs in redisplay occurring when displaying prompts containing
+    invisible characters.
+
+f.  Fixed a bug that caused the completion append character to not be reset to

+    or no characters following the final newline.
+
+k.  Fixed redisplay bug caused by prompts consisting solely of invisible
+    characters.
+
+l.  Fixed a bug in the code that buffers characters received very quickly in
+    succession which caused characters to be dropped.
+
+m.  Fixed a bug that caused readline to reference uninitialized data structures
+    if it received a SIGWINCH before completing initialization.
+
+n.  Fixed a bug that caused the vi-mode `last command' to be set incorrectly
+    and therefore unrepeatable.
+
+o.  Fixed a bug that caused readline to disable echoing when it was being used
+    with an output file descriptor that was not a terminal.
+
+p.  Readline now blocks SIGINT while manipulating internal data structures
+    during redisplay.
+
+q.  Fixed a bug in redisplay that caused readline to segfault when pasting a
+    very long line (over 130,000 characters).
+
+r.  Fixed bugs in redisplay when using prompts with no visible printing
+    characters.
+
+3.  New Features in Bash
+
+a.  When using substring expansion on the positional parameters, a starting
+    index of 0 now causes $0 to be prefixed to the list.
+
+b.  The `help' builtin now prints its columns with entries sorted vertically
+    rather than horizontally.
+
+c.  There is a new variable, $BASHPID, which always returns the process id of
+    the current shell.
+
+d.  There is a new `autocd' option that, when enabled, causes bash to attempt
+    to `cd' to a directory name that is supplied as the first word of a
+    simple command.
+
+e.  There is a new `checkjobs' option that causes the shell to check for and
+    report any running or stopped jobs at exit.
+
+f.  The programmable completion code exports a new COMP_TYPE variable, set to
+    a character describing the type of completion being attempted.
+
+g.  The programmable completion code exports a new COMP_KEY variable, set to
+    the character that caused the completion to be invoked (e.g., TAB).
+
+h.  If creation of a child process fails due to insufficient resources, bash
+    will try again several times before reporting failure.
+
+i.  The programmable completion code now uses the same set of characters as
+    readline when breaking the command line into a list of words.
+
+j.  The block multiplier for the ulimit -c and -f options is now 512 when in
+    Posix mode, as Posix specifies.
+
+k.  Changed the behavior of the read builtin to save any partial input received
+    in the specified variable when the read builtin times out.  This also
+    results in variables specified as arguments to read to be set to the empty
+    string when there is no input available.  When the read builtin times out,
+    it returns an exit status greater than 128.
+
+l.  The shell now has the notion of a `compatibility level', controlled by
+    new variables settable by `shopt'.  Setting this variable currently
+    restores the bash-3.1 behavior when processing quoted strings on the rhs
+    of the `=~' operator to the `[[' command.
+
+m.  The `ulimit' builtin now has new -b (socket buffer size) and -T (number
+    of threads) options.
+
+n.  The -p option to `declare' now displays all variable values and attributes
+    (or function values and attributes if used with -f).
+
+o.  There is a new `compopt' builtin that allows completion functions to modify
+    completion options for existing completions or the completion currently
+    being executed.
+
+p.  The `read' builtin has a new -i option which inserts text into the reply
+    buffer when using readline.
+
+q.  A new `-E' option to the complete builtin allows control of the default
+    behavior for completion on an empty line.
+
+r.  There is now limited support for completing command name words containing
+    globbing characters.
+
+s.  Changed format of internal help documentation for all builtins to roughly
+    follow man page format.
+
+t.  The `help' builtin now has a new -d option, to display a short description,
+    and a -m option, to print help information in a man page-like format.
+
+u.  There is a new `mapfile' builtin to populate an array with lines from a
+    given file.
+
+v.  If a command is not found, the shell attempts to execute a shell function
+    named `command_not_found_handle', supplying the command words as the
+    function arguments.
+
+w.  There is a new shell option: `globstar'.  When enabled, the globbing code
+    treats `**' specially -- it matches all directories (and files within
+    them, when appropriate) recursively.
+
+x.  There is a new shell option: `dirspell'.  When enabled, the filename
+    completion code performs spelling correction on directory names during
+    completion.
+
+y.  The `-t' option to the `read' builtin now supports fractional timeout
+    values.
+
+z.  Brace expansion now allows zero-padding of expanded numeric values and
+    will add the proper number of zeroes to make sure all values contain the
+    same number of digits.
+
+aa. There is a new bash-specific bindable readline function: `dabbrev-expand'.
+    It uses menu completion on a set of words taken from the history list.
+
+bb. The command assigned to a key sequence with `bind -x' now sets two new
+    variables in the environment of the executed command:  READLINE_LINE_BUFFER
+    and READLINE_POINT.  The command can change the current readline line
+    and cursor position by modifying READLINE_LINE_BUFFER and READLINE_POINT,
+    respectively.
+
+cc. There is a new &>> redirection operator, which appends the standard output
+    and standard error to the named file.
+
+dd. The parser now understands `|&' as a synonym for `2>&1 |', which redirects
+    the standard error for a command through a pipe.
+
+ee. The new `;&' case statement action list terminator causes execution to
+    continue with the action associated with the next pattern in the
+    statement rather than terminating the command.
+
+ff. The new `;;&' case statement action list terminator causes the shell to
+    test the next set of patterns after completing execution of the current
+    action, rather than terminating the command.
+
+gg. The shell understands a new variable: PROMPT_DIRTRIM.  When set to an
+    integer value greater than zero, prompt expansion of \w and \W  will
+    retain only that number of trailing pathname components and replace
+    the intervening characters with `...'.
+
+hh. There are new case-modifying word expansions: uppercase (^[^]) and
+    lowercase (,[,]).  They can work on either the first character or
+    array element, or globally.  They accept an optional shell pattern
+    that determines which characters to modify.  There is an optionally-
+    configured feature to include capitalization operators.
+
+ii. The shell provides associative array variables, with the appropriate
+    support to create, delete, assign values to, and expand them.
+
+jj. The `declare' builtin now has new -l (convert value to lowercase upon
+    assignment) and -u (convert value to uppercase upon assignment) options.
+    There is an optionally-configurable -c option to capitalize a value at
+    assignment.
+
+kk. There is a new `coproc' reserved word that specifies a coprocess: an
+    asynchronous command run with two pipes connected to the creating shell.
+    Coprocs can be named.  The input and output file descriptors and the
+    PID of the coprocess are available to the calling shell in variables
+    with coproc-specific names.
+
+4.  New Features in Readline
+
+a.  A new variable, rl_sort_completion_matches; allows applications to inhibit
+    match list sorting (but beware: some things don't work right if
+    applications do this).
+
+b.  A new variable, rl_completion_invoking_key; allows applications to discover
+    the key that invoked rl_complete or rl_menu_complete.
+
+c.  The functions rl_block_sigint and rl_release_sigint are now public and
+    available to calling applications who want to protect critical sections
+    (like redisplay).
+
+d.  The functions rl_save_state and rl_restore_state are now public and
+    available to calling applications; documented rest of readline's state
+    flag values.
+
+e.  A new user-settable variable, `history-size', allows setting the maximum
+    number of entries in the history list.
+
+f.  There is a new implementation of menu completion, with several improvements
+    over the old; the most notable improvement is a better `completions
+    browsing' mode.
+
+g.  The menu completion code now uses the rl_menu_completion_entry_function
+    variable, allowing applications to provide their own menu completion
+    generators.
+
+h.  There is support for replacing a prefix  of a pathname with a `...' when
+    displaying possible completions.  This is controllable by setting the
+    `completion-prefix-display-length' variable.  Matches with a common prefix
+    longer than this value have the common prefix replaced with `...'.
+
+i.  There is a new `revert-all-at-newline' variable.  If enabled, readline will
+    undo all outstanding changes to all history lines when `accept-line' is
+    executed.
+

+
+a.  Fixed a bug that caused the temporary environment passed to a command to
+    affect the shell's environment under certain circumstances.

+    ignore empty string arguments.
+
+c.  Improved multibyte character environment detection at configuration time.
+
+d.  Fixed a bug in the read builtin that left spurious escape characters in the
+    input after processing backslashes when assigning to an array variable.
+
+2.  Changes to Readline
+
+a.  Fixed a redisplay bug that occurred in multibyte-capable locales when the
+    prompt was one character longer than the screen width.
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.2-beta,
+and the previous version, bash-3.2-alpha.
+
+1.  Changes to Bash
+
+a.  Changed the lexical analyzer to treat locale-specific blank characters as
+    white space.
+
+b.  Fixed a bug in command printing to avoid confusion between redirections and
+    process substitution.
+
+c.  Fixed problems with cross-compiling originating from inherited environment
+    variables.
+
+d.  Added write error reporting to printf builtin.
+
+e.  Fixed a bug in the variable expansion code that could cause a core dump in
+    a multi-byte locale.
+
+f.  Fixed a bug that caused substring expansion of a null string to return
+    incorrect results.
+
+g.  BASH_COMMAND now retains its previous value while executing commands as the
+    result of a trap, as the documentation states.
+
+2.  Changes to Readline
+
+a.  Fixed a bug with prompt redisplay in a multi-byte locale to avoid redrawing
+    the prompt and input line multiple times.
+
+b.  Fixed history expansion to not be confused by here-string redirection.
+
+c.  Readline no longer treats read errors by converting them to newlines, as
+    it does with EOF.  This caused partial lines to be returned from readline().
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.2-alpha,
+and the previous version, bash-3.1-release.
+
+1.  Changes to Bash
+
+a.  Fixed a source bug that caused the minimal configuration to not compile.
+
+b.  Fixed memory leaks in error handling for the `read' builtin.
+
+c.  Changed the [[ and (( compound commands to set PIPESTATUS with their exit
+    status.
+
+d.  Fixed some parsing problems with compound array assignments.
+
+e.  Added additional configuration changes for: NetBSD (incomplete multibyte
+    character support)
+
+f.  Fixed two bugs with local array variable creation when shadowing a variable
+    of the same name from a previous context.
+
+g.  Fixed the `read' builtin to restore the correct set of completion functions
+    if a timeout occurs.
+
+h.  Added code to defer the initialization of HISTSIZE (and its stifling of the
+    history list) until the history file is loaded, allowing a startup file to
+    override the default value.
+
+i.  Tightened up the arithmetic expression parsing to produce better error
+    messages when presented with invalid operators.
+
+j.  Fixed the cross-compilation support to build the signal list at shell
+    invocation rather than compile time if cross-compiling.
+
+k.  Fixed multibyte support for non-gcc compilers (or compilers that do not
+    allow automatic array variable sizing based on a non-constant value).
+
+l.  Several fixes to the code that manages the list of terminated jobs and
+    their exit statuses, and the list of active and recently-terminated jobs
+    to avoid pid aliasing/wraparound and allocation errors.
+
+m.  Fixed a problem that allowed scripts to die due to SIGINT while waiting
+    for children, even when started in the background or otherwise ignoring
+    SIGINT.
+
+n.  Fixed a bug that caused shells invoked as -/bin/bash from not being
+    recognized as login shells.
+
+o.  Fixed a problem that caused shells in the background to give the terminal
+    to a process group other than the foreground shell process group.
+
+p.  Fixed a problem with extracting the `varname' in ${#varname}.
+
+q.  Fixed the code that handles SIGQUIT to not exit immediately -- thereby
+    calling functions that may not be called in a signal handler context --
+    but set a flag and exit afterward (like SIGINT).
+
+r.  Changed the brace expansion code to skip over braces that don't begin a
+    valid matched brace expansion construct.
+
+s.  Fixed `typeset' and `declare' to not require that their shell function
+    operands to be valid shell identifiers.
+
+t.  Changed `test' to use access(2) with a temporary uid/euid swap when testing
+    file attributes and running setuid, and access(2) in most other cases.
+
+u.  Changed completion code to not attempt command name completion on a line
+    consisting solely of whitespace when no_empty_command_completion is set.
+
+v.  The `hash' builtin now prints nothing in posix mode when the hash table is
+    empty, and prints a message to that effect to stdout instead of stderr
+    when not in posix mode.
+
+w.  Fixed a bug in the extended pattern matching code that caused it to fail to
+    match periods with certain patterns.
+
+x.  Fixed a bug that caused the shell to dump core when performing filename
+    generation in directories with thousands of files.
+
+y.  Returned to the original Bourne shell rules for parsing ``:  no recursive
+    parsing of embedded quoted strings or ${...} constructs.
+
+z.  The inheritance of the DEBUG, RETURN, and ERR traps is now dependent only
+    on the settings of the `functrace' and `errtrace' shell options, rather
+    than whether or not the shell is in debugging mode.
+
+aa. Fixed a problem with $HOME being converted to ~ in the expansion of
+    members of the DIRSTACK array.
+
+bb. Fixed a problem with quoted arguments to arithmetic expansions in certain
+    constructs.
+
+cc. The command word completion code now no longer returns matching directories
+    while searching $PATH.
+
+dd. Fixed a bug with zero-padding and precision handling in snprintf()
+    replacement.
+
+ee. Fixed a bug that caused the command substitution code not to take embedded
+    shell comments into account.
+
+ff. Fixed a bug that caused $((...);(...)) to be misinterpreted as an
+    arithmetic substitution.
+
+gg. Fixed a bug in the prompt expansion code that inappropriately added a
+    \001 before a \002 under certain circumstances.
+
+hh. Fixed a bug that caused `unset LANG' to not properly reset the locale
+    (previous versions would set the locale back to what it was when bash
+    was started rather than the system's "native" locale).
+
+ii. Fixed a bug that could cause file descriptors > 10 to not be closed even
+    when closed explicitly by a script.
+
+jj. Fixed a bug that caused single quotes to be stripped from ANSI-C quoting
+    inside double-quoted command substitutions.
+
+kk. Fixed a bug that could cause core dumps when `return' was executed as the
+    last element of a pipeline inside a shell function.
+
+ll. Fixed a bug that caused DEBUG trap strings to overwrite commands stored in
+    the jobs list.
+
+2.  Changes to Readline
+
+a.  Fixed a problem that caused segmentation faults when using readline in
+    callback mode and typing consecutive DEL characters on an empty line.
+
+b.  Fixed several redisplay problems with multibyte characters, all having to
+    do with the different code paths and variable meanings between single-byte
+    and multibyte character redisplay.
+
+c.  Fixed a problem with key sequence translation when presented with the
+    sequence \M-\C-x.
+
+d.  Fixed a problem that prevented the `a' command in vi mode from being
+    undone and redone properly.
+
+e.  Fixed a problem that prevented empty inserts in vi mode from being undone
+    properly.
+
+f.  Fixed a problem that caused readline to initialize with an incorrect idea
+    of whether or not the terminal can autowrap.
+
+g.  Fixed output of key bindings (like bash `bind -p') to honor the setting of
+    convert-meta and use \e where appropriate.
+
+h.  Changed the default filename completion function to call the filename
+    dequoting function if the directory completion hook isn't set.  This means
+    that any directory completion hooks need to dequote the directory name,
+    since application-specific hooks need to know how the word was quoted,
+    even if no other changes are made.
+
+i.  Fixed a bug with creating the prompt for a non-interactive search string
+    when there are non-printing characters in the primary prompt.
+
+j.  Fixed a bug that caused prompts with invisible characters to be redrawn
+    multiple times in a multibyte locale.
+
+k.  Fixed a bug that could cause the key sequence scanning code to return the
+    wrong function.
+
+l.  Fixed a problem with the callback interface that caused it to fail when
+    using multi-character keyboard macros.
+
+m.  Fixed a bug that could cause a core dump when an edited history entry was
+    re-executed under certain conditions.
+
+n.  Fixed a bug that caused readline to reference freed memory when attmpting
+    to display a portion of the prompt.
+
+3.  New Features in Bash
+
+a.  Changed the parameter pattern replacement functions to not anchor the
+    pattern at the beginning of the string if doing global replacement - that
+    combination doesn't make any sense.
+
+b.  When running in `word expansion only' mode (--wordexp option), inhibit
+    process substitution.
+
+c.  Loadable builtins now work on MacOS X 10.[34].
+
+d.  Shells running in posix mode no longer set $HOME, as POSIX requires.
+
+e.  The code that checks for binary files being executed as shell scripts now
+    checks only for NUL rather than any non-printing character.
+
+f.  Quoting the string argument to the [[ command's  =~ operator now forces
+    string matching, as with the other pattern-matching operators.
+
+4.  New Features in Readline
+
+a.  Calling applications can now set the keyboard timeout to 0, allowing
+    poll-like behavior.
+
+b.  The value of SYS_INPUTRC (configurable at compilation time) is now used as
+    the default last-ditch startup file.
+
+c.  The history file reading functions now allow windows-like \r\n line
+    terminators.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.1-release,
+and the previous version, bash-3.1-rc2.
+
+1.  Changes to Readline
+
+a.  Several changes to the multibyte redisplay code to fix problems with
+    prompts containing invisible characters.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.1-rc2,
+and the previous version, bash-3.1-rc1.
+
+1.  Changes to Bash
+
+a.  Fixed a bug that caused a DEBUG trap to overwrite a command string that's
+    eventually attached to a background job.
+
+b.  Changed some code so that filenames with leading tildes with spaces in the
+    name aren't tilde-expanded by the bash completion code.
+
+c.  Fixed a bug that caused the pushd builtin to fail to change to
+    directories with leading `-'.
+
+d.  Fixed a small memory leak in the programmable completion code.
+
+2.  Changes to Readline
+
+a.  Fixed a redisplay bug caused by moving the cursor vertically to a line
+    with invisible characters in the prompt in a multibyte locale.
+
+b.  Fixed a bug that could cause the terminal special chars to be bound in the
+    wrong keymap in vi mode.
+
+3.  New Features in Bash
+
+a.  If compiled for strict POSIX conformance, LINES and COLUMNS may now
+    override the true terminal size.
+
+4.  New Features in Readline
+
+a.  A new external application-controllable variable that allows the LINES
+    and COLUMNS environment variables to set the window size regardless of
+    what the kernel returns.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.1-rc1,
+and the previous version, bash-3.1-beta1.
+
+1.  Changes to Bash
+
+a.  Fixed a bug that could cause core dumps due to accessing the current
+    pipeline while in the middle of modifying it.
+
+b.  Fixed a bug that caused pathnames with backslashes still quoting characters
+    to be passed to opendir().
+
+c.  Command word completion now obeys the setting of completion-ignore-case.
+
+d.  Fixed a problem with redirection that caused file descriptors greater than
+    2 to be inappropriately marked as close-on-exec.
+
+e.  In Posix mode, after `wait' is called to wait for a particular process
+    explicitly, that process is removed from the list of processes known to
+    the shell, and subsequent attempts to wait for it return errors.
+
+f.  Fixed a bug that caused extended pattern matching to incorrectly scan
+    backslash-escaped pattern characters.
+
+g.  Fixed a synchronization problem that could cause core dumps when handling
+    a SIGWINCH.
+
+h.  Fixed a bug that caused an unmatched backquote to be accepted without an
+    error when processing here documents.
+
+i.  Fixed a small memory leak in the `cd' builtin.
+
+j.  Fix for MacOS X so it gets the values for the HOSTTYPE, MACHTYPE, and
+    OSTYPE variables at build time, to support universal binaries.
+
+k.  Fixed a bug that could cause an exit trap to return the exit status of
+    the trap command rather than the status as it was before the trap was
+    run as the shell's exit status.
+
+2.  New Features in Bash
+
+3.  Changes to Readline
+
+a.  Fixed a bug that caused reversing the incremental search direction to
+    not work correctly.
+
+b.  Fixed the vi-mode `U' command to only undo up to the first time insert mode
+    was entered, as Posix specifies.
+
+c.  Fixed a bug in the vi-mode `r' command that left the cursor in the wrong
+    place.
+
+4.  New Features in Readline
+
+a.  New application-callable auxiliary function, rl_variable_value, returns
+    a string corresponding to a readline variable's value.
+
+b.  When parsing inputrc files and variable binding commands, the parser
+    strips trailing whitespace from values assigned to boolean variables
+    before checking them.
+
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.1-beta1,
+and the previous version, bash-3.1-alpha1.
+
+1.  Changes to Bash
+
+a.  Added some system-specific signal names.
+
+b.  Fixed a typo in the ulimit builtin to make `x' the right option to
+    manipulate the limit on file locks.
+
+c.  Fixed a problem with using += to append to index 0 of an array variable
+    when not using subscript syntax.
+
+d.  A few changes to configure.in to remove calls to obsolete or outdated
+    macros.
+
+e.  Make sure changes to variables bash handles specially (e.g., LC_ALL) are
+    made when the variable is set in the temporary environment to a command.
+
+f.  Make sure changes to variables bash handles specially (e.g., LC_ALL) are
+    made when the variable is modified using `printf -v'.
+
+g.  The export environment is now remade on cygwin when HOME is changed, so
+    DLLs bash is linked against pick up the new value.  This fixes problems
+    with tilde expansion when linking against and already-installed readline.
+
+h.  Small fix to the logic for performing tilde expansion in posix mode, so
+    expansion on the right-hand side of an assignment statement takes place.
+
+i.  Fixed a bug that prevented redirections associated with a shell function
+    from being executed when in a subshell.
+
+j.  Fixed `source' and `.' builtins to not require an executable file when
+    searching $PATH for a file to source.
+
+k.  Fixed a bug that caused incorrect word splitting in a function when IFS
+    was declared local, then unset.
+
+l.  Fixed a problem with the `kill' builtin that prevented sending signals
+    to a process group under certain circumstances when providing a pid < 0.
+
+m.  When in POSIX mode, `pwd' now checks that the value it prints is the same
+    directory as `.', even when displaying $PWD.
+
+n.  Fixed a problem with the `read' builtin when reading a script from standard
+    input and reading data from the same file.
+
+o.  Fixed a problem with the `type' and `command' builtins that caused absolute
+    pathnames to be displayed incorrectly.
+
+p.  Some changes to the `bg' builtin for POSIX conformance.
+
+q.  The `fc' builtin now removes the `fc' command that caused it to invoke an
+    editor on specified history entries from the history entirely, rather than
+    simply ignoring it.
+
+r.  When in POSIX mode, the `v' command in vi editing mode simply invokes vi
+    on the current command, rather than checking $FCEDIT and $EDITOR.
+
+s.  Fixed a small memory leak in the pathname canonicalization code.
+
+t.  Fixed a bug that caused the expanded value of a $'...' string to be
+    incorrectly re-quoted if it occurred within a double-quoted ${...}
+    parameter expansion.
+
+u.  Restored default emacs-mode key binding of M-TAB to dynamic-complete-history.
+
+v.  Fixed a bug that caused core dumps when interrupting loops running builtins
+    on some systems.
+
+w.  Make sure that some of the functions bash provides replacements for are
+    not cpp defines.
+
+x.  The code that scans embedded commands for the parser (`...` and $(...)) is
+    now more aware of embedded comments and their effect on quoted strings.
+
+y.  Changed the `-n' option to the `history' builtin to not reset the number of
+    history lines read in the current session after reading the new lines from
+    the history file if the history is being appended when it is written to
+    the file, since the appending takes care of the problem that the adjustment
+    was intended to solve.
+
+z.  Improved the error message displayed when a shell script fails to execute
+    because the environment and size of command line arguments are too large.
+
+aa. A small fix to make sure that $HISTCMD is evaluated whenever the shell is
+    saving commands to the history list, not just when HISTSIZE is defined.
+
+2.  Changes to Readline
+
+a.  The `change-case' command now correctly changes the case of multibyte
+    characters.
+
+b.  Changes to the shared library construction scripts to deal with Windows
+    DLL naming conventions for Cygwin.
+
+c.  Fixed the redisplay code to avoid core dumps resulting from a poorly-timed
+    SIGWINCH.
+
+d.  Fixed the non-incremental search code in vi mode to dispose of any current
+    undo list when copying a line from the history into the current editing
+    buffer.
+
+e.  The variable assignment code now ignores whitespace at the end of lines
+    when assigning to boolean variables.
+
+f.  The `C-w' binding in incremental search now understands multibyte
+    characters.
+
+3.  New Features in Bash
+
+a.  A new configuration option, `--enable-strict-posix-default', which will
+    build bash to be POSIX conforming by default.
+
+4.  New Features in Readline
+
+a.  If the rl_completion_query_items is set to a value < 0, readline never
+    asks the user whether or not to view the possible completions.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.1-alpha1,
+and the previous version, bash-3.0-release.
+
+1.  Changes to Bash
+
+a.  Fixed a bug that caused bash to crash if referencing an unset local array.
+
+b.  Fixed a problem that caused tilde expansion to not be performed before
+    attempting globbing word completion.
+
+c.  Fixed an incompatibility so that a first argument to trap that's a valid
+    signal number will be trated as a signal rather than a command to execute.
+
+d.  Fixed ${#word} expansion to correctly compute the length of a string
+    containing multibyte characters.
+
+e.  Fixed a bug that caused bash to not pass the correct flags for signal
+    disposition to child processes.
+
+f.  Fixed a bug that caused `fc -l' to list one too many history entries.
+
+g.  Some fixes to `fc' for POSIX conformance.
+
+h.  Some fixes to job status display for POSIX conformance.
+
+i.  Fixed a bug that caused `command -v' to display output if a command was not
+    found -- it should be silent.
+
+j.  In POSIX mode, `type' and `command -[vV]' do not report non-executable
+    files, even if the shell will attempt to execute them.
+
+k.  Fixed a bug that caused the `==' operator to the [[ command to not attempt
+    extended pattern matching.
+
+l.  Fixed the brace expansion code to handle characters whose value exceeds 128.
+
+m.  Fixed `printf' to handle strings with a leading `\0' whose length is
+    non-zero.
+
+n.  Fixed a couple of problems with brace expansion where `${' was handled
+    incorrectly.
+
+o.  Fixed off-by-one error when calculating the upper bound of `offset' when
+    processing the ${array[@]:offset:length} expansion.
+
+p.  System-specific configuration changes for: FreeBSD 5.x, Interix, MacOS X
+    10.4, Linux 2.4+ kernels, Linux 3.x kernels, Dragonfly BSD, QNX 6.x,
+    Cygwin
+
+q.  Fixed a bug that caused the shell to ignore the status of the rightmost
+    command in a pipeline when the `pipefail' option was enabled.
+
+r.  Fixed a completion bug that caused core dumps when expanding a directory
+    name.
+
+s.  Fixed a bug that prevented `hash -d' from removing commands from the hash
+    table.
+
+t.  Fixed word splitting to avoid really bad quadratic performance when
+    expanding long lists.
+
+u.  Fixed a bug that caused negative offsets in substring expansion to use the
+    wrong values.
+
+v.  Fixed a bug in printf that caused it to not return failure on write errors.
+
+w.  Fixed a bug that caused commands in subshells to not be properly timed.
+
+x.  The shell parser no longer attempts to parse a compound assignment specially
+    unless in a position where an assignment statement is acceptable or parsing
+    arguments to a builtin that accepts assignment statements.
+
+y.  Fixed a problem that caused a `case' statement to be added to the history
+    incorrectly as a single command if the `case word' was on one line and the
+    `in' on another.
+
+z.  Fixed a problem that caused internal shell quoting characters to be
+    incorrectly quoted with backslashes under some circumstances.
+
+aa. The shell now performs correct word splitting when IFS contains multibyte
+    characters.
+
+bb. The mail checking code now resets the cached file information if the size
+    drops to 0, even if the times don't change.
+
+cc. A completed command name that is found in $PATH as well as the name of a
+    directory in the current directory no longer has a slash appended in certain
+    circumstances:  a single instance found in $PATH when `.' is not in $PATH,
+    and multiple instances found in $PATH, even when `.' is in $PATH.
+
+dd. Incorporated tilde expansion into the word expansion code rather than as a
+    separately-called function, fixing some cases where it was performed
+    inappropriately (e.g., after the second `=' in an assignment statement or
+    in a double-quoted parameter expansion).
+
+ee. Fixed several bugs encountered when parsing compound assignment statements,
+    so that compound assignments appearing as arguments to builtins are no
+    longer double-expanded.
+
+ff. Fixed a bug in the command execution code that caused asynchronous commands
+    containing command substitutions to not put the terminal in the wrong
+    process group.
+
+gg. Bash now handles the case where the WCONTINUED flag causes waitpid() to
+    return -1/EINVAL at runtime as well as configuration time.
+
+hh. Fixed parser to generate an error when the pipeline `argument' to `!' or
+    `time' is NULL.
+
+ii. The shell now takes a little more care when manipulating file descriptors
+    greater than 9 with the `exec' builtin.
+
+jj. Fixed a bug that caused variable assignments preceding the `command' builtin
+    preceding a special builtin to be preserved after the command completed in
+    POSIX mode.
+
+kk. Fixed a bug that allowed variables beginning with a digit to be created.
+
+ll. Fixed a bug that caused a \<newline> to be removed when parsing a $'...'
+    construct.
+
+mm. A shell whose name begins with `-' will now be a restricted shell if the
+    remainder of the name indicates it should be restricted.
+
+nn. Fixed a bug that could cause a core dump if FUNCNAME were changed or unset
+    during a function's execution.
+
+oo. Fixed a bug that caused executing a `return' in a function to not execute
+    a RETURN trap.  The RETURN trap is inherited by shell functions only if
+    function tracing is globally enabled or has been enabled for that function.
+
+pp. Fixed cases where var[@] was not handled exactly like var, when var is a
+    scalar variable.
+
+qq. Fixed a bug that caused the first character after a SIGINT to be discarded
+    under certain circumstances.
+
+rr. Fixed exit status code so that a suspended job returns 128+signal as its
+    exit status (preventing commands after it in `&&' lists from being
+    executed).
+
+ss. Fixed a bug that caused the shell parser state to be changed by executing
+    a shell function as a result of word completion.
+
+tt. Fixed a long-standing bug that caused '\177' characters in variable
+    values to be discarded when expanded in double-quoted strings.
+
+uu. Fixed a bug that caused $RANDOM to be re-seeded multiple times in a
+    subshell environment.
+
+vv. Extensive changes to the job management code to avoid the pid-reuse and
+    pid-aliasing problems caused by retaining the exit status of too many jobs,
+    but still retain as many background job statuses as POSIX requires.
+
+ww. Fixed a parser bug in processing \<newline> that caused things like
+
+		((echo 5) \
+		 (echo 6))
+
+    to not work correctly.
+
+xx. `pwd -P' now sets $PWD to a directory name containing no symbolic links
+    when in posix mode, as POSIX requires.
+
+yy. In posix mode, bash no longer sets $PWD to a name containing no symbolic
+    links if a directory is chosen from $CDPATH.
+
+zz. The word splitting code now treats an IFS character that is not space,
+    tab, or newline and any adjacent IFS white space as a single delimiter, as
+    SUSv3/XPG6 require.
+
+aaa. The `read' builtin now checks whether or not the number of fields read is
+     exactly the same as the number of variables instead of just assigning the
+     rest of the line (minus any trailing IFS white space) to the last
+     variable.  This is what POSIX/SUS/XPG all require.
+
+bbb. Fixed a bug that caused `read' to always check whether or not fd 0 was a
+     pipe, even when reading from another file descriptor.
+
+ccc. Fixed a bug that caused short-circuiting of execution even if the return
+     value was being inverted.
+
+ddd. Fixed a bug that caused a core dump while decoding \W escapes in PS1 if
+     PWD was unset.
+
+eee. Fixed a bug in `read' that counted internal quoting characters for the
+     purposes of `read -n'.
+
+fff. Fixed a bug so that a function definition in a pipeline causes a child
+     process to be forked at the right time.
+
+ggg. Bash will not attempt to link against a readline library that doesn't
+     have rl_gnu_readline_p == 1.
+
+hhh. Fixed a bug that caused `read' to consume one too many characters when
+     reading a fixed number of characters and the Nth character is a backslash.
+
+iii. Fixed a bug that caused `unset' on variables in the temporary environment
+     to leave them set when `unset' completed.
+
+jjj. Fixed a bug that caused bash to close fd 2 if an `exec' failed and the
+     shell didn't exit.
+
+kkk. The completion code is more careful to not turn `/' or `///' into `//',
+     for those systems on which `//' has special meaning.
+
+lll. Fixed a bug that caused command substitution in asynchronous commands to
+     close the wrong file descriptors.
+
+mmm. The shell no longer prints status messages about terminated background
+     processes unless job control is active.
+
+nnn. Fixed a bug that prevented multiple consecutive invocations of `history -s'
+     from adding all the commands to the history list.
+
+ooo. Added a couple of changes to make arithmetic expansion more consistent in
+     all its contexts (still not perfect).
+
+ppp. Fixed a bug that caused the parser to occasionally not find the right
+     terminating "`" in an old-style command substitution.
+
+qqq. Fixed a bug that caused core dumps when the shell was reading its non-
+     interactive input from fd 0 and fd 0 was duplicated and restored using a
+     combination of `exec' (to save) and redirection (to restore).
+
+rrr. Fixed a problem that caused loops in sourced scripts to not be cleaned
+     up properly when a `return' is executed.
+
+sss. Change internal command substitution completion function to append a slash
+     to directory names in the command.
+
+2.  Changes to Readline
+
+a.  Fixed a bug that caused multiliine prompts to be wrapped and displayed
+    incorrectly.
+
+b.  Fixed a bug that caused ^P/^N in emacs mode to fail to display the current
+    line correctly.
+
+c.  Fixed a problem in computing the number of invisible characters on the first
+    line of a prompt whose length exceeds the screen width.
+
+d.  Fixed vi-mode searching so that failure preserves the current line rather
+    than the last line in the history list.
+
+e.  Fixed the vi-mode `~' command (change-case) to have the correct behavior at
+    end-of-line when manipulating multibyte characters.
+
+f.  Fixed the vi-mode `r' command (change-char) to have the correct behavior at
+    end-of-line when manipulating multibyte characters.
+
+g.  Fixed multiple bugs in the redisplay of multibyte characters:  displaying
+    prompts longer than the screen width containing multibyte characters, 
+
+h.  Fix the calculation of the number of physical characters in the prompt
+    string when it contains multibyte characters.
+
+i.  A non-zero value for the `rl_complete_suppress_append' variable now causes
+    no `/' to be appended to a directory name.
+
+j.  Fixed forward-word and backward-word to work when words contained
+    multibyte characters.
+
+k.  Fixed a bug in finding the delimiter of a `?' substring when performing
+    history expansion in a locale that supports multibyte characters.
+
+l.  Fixed a memory leak caused by not freeing the timestamp in a history entry.
+
+m.  Fixed a bug that caused "\M-x" style key bindings to not obey the setting
+    of the `convert-meta' variable.
+
+n.  Fixed saving and restoring primary prompt when prompting for incremental
+    and non-incremental searches; search prompts now display multibyte
+    characters correctly.
+
+o.  Fixed a bug that caused keys originally bound to self-insert but shadowed
+    by a multi-character key sequence to not be inserted.
+
+p.  Fixed code so rl_prep_term_function and rl_deprep_term_function aren't
+    dereferenced if NULL (matching the documentation).
+
+q.  Extensive changes to readline to add enough state so that commands
+    requiring additional characters (searches, multi-key sequences, numeric
+    arguments, commands requiring an additional specifier character like
+    vi-mode change-char, etc.) work without synchronously waiting for
+    additional input.
+
+r.  Lots of changes so readline builds and runs on MinGW.
+
+s.  Readline no longer tries to modify the terminal settings when running in
+    callback mode.
+
+t.  The Readline display code no longer sets the location of the last invisible
+    character in the prompt if the \[\] sequence is empty.
+
+3.  New Features in Bash
+
+a.  Bash now understands LC_TIME as a special variable so that time display
+    tracks the current locale.
+
+b.  BASH_ARGC, BASH_ARGV, BASH_SOURCE, and BASH_LINENO are no longer created
+    as `invisible' variables and may not be unset.
+
+c.  In POSIX mode, if `xpg_echo' option is enabled, the `echo' builtin doesn't
+    try to interpret any options at all, as POSIX requires.
+
+d.  The `bg' builtin now accepts multiple arguments, as POSIX seems to specify.
+
+e.  Fixed vi-mode word completion and glob expansion to perform tilde
+    expansion.
+
+f.  The `**' mathematic exponentiation operator is now right-associative.
+
+g.  The `ulimit' builtin has new options: -i (max number of pending signals),
+    -q (max size of POSIX message queues), and -x (max number of file locks).
+
+h.  A bare `%' once again expands to the current job when used as a job
+    specifier.
+
+i.  The `+=' assignment operator (append to the value of a string or array) is
+    now supported for assignment statements and arguments to builtin commands
+    that accept assignment statements.
+
+j.  BASH_COMMAND now preserves its value when a DEBUG trap is executed.
+
+k.  The `gnu_errfmt' option is enabled automatically if the shell is running
+    in an emacs terminal window.
+
+l.  New configuration option:  --single-help-strings.  Causes long help text
+    to be written as a single string; intended to ease translation.
+
+m.  The COMP_WORDBREAKS variable now causes the list of word break characters
+    to be emptied when the variable is unset.
+
+n.  An unquoted expansion of $* when $IFS is empty now causes the positional
+    parameters to be concatenated if the expansion doesn't undergo word
+    splitting.
+
+o.  Bash now inherits $_ from the environment if it appears there at startup.
+
+p.  New shell option: nocasematch.  If non-zero, shell pattern matching ignores
+    case when used by `case' and `[[' commands.
+
+q.  The `printf' builtin takes a new option: -v var.  That causes the output
+    to be placed into var instead of on stdout.
+
+r.  By default, the shell no longer reports processes dying from SIGPIPE.
+
+s.  Bash now sets the extern variable `environ' to the export environment it
+    creates, so C library functions that call getenv() (and can't use the
+    shell-provided replacement) get current values of environment variables.
+
+4.  New Features in Readline
+
+a.  The key sequence sent by the keypad `delete' key is now automatically
+    bound to delete-char.
+
+b.  A negative argument to menu-complete now cycles backward through the
+    completion list.
+
+c.  A new bindable readline variable:  bind-tty-special-chars.  If non-zero,
+    readline will bind the terminal special characters to their readline
+    equivalents when it's called (on by default).
+
+d.  New bindable command: vi-rubout.  Saves deleted text for possible
+    reinsertion, as with any vi-mode `text modification' command; `X' is bound
+    to this in vi command mode.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.0-release,
+and the previous version, bash-3.0-rc1.
+
+1.  Changes to Bash
+
+a.  Fixed a boundary overrun that could cause segmentation faults when the
+    completion code hands an incomplete construct to the word expansion
+    functions.
+
+b.  Changed posix mode behavior so that an error in a variable assignment
+    preceding a special builtin causes a non-interactive shell to exit.
+
+c.  Change the directory expansion portion of the completion code to not
+    expand embedded command substitutions if the directory name appears in
+    the file system.
+
+d.  Fixed a problem that caused `bash -r' to turn on restrictions before
+    reading the startup files.
+
+e.  Fixed a problem with the default operation of the `umask' builtin.
+
+2.  Changes to Readline
+
+a.  Fixed a problem with readline saving the contents of the current line
+    before beginning a non-interactive search.
+
+b.  Fixed a problem with EOF detection when using rl_event_hook.
+
+c.  Fixed a problem with the vi mode `p' and `P' commands ignoring numeric
+    arguments.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.0-rc1,
+and the previous version, bash-3.0-beta1.
+
+1.  Changes to Bash
+
+a.  Fixed a bug that caused incorrect behavior when referecing element 0 of
+    an array using $array, element 0 was unset, and `set -u' was enabled.
+
+b.  System-specific changes for: SCO Unix 3.2, Tandem.
+
+c.  Fixed a bug that caused inappropriate word splitting when a variable was
+    expanded within a double-quoted string that also included $@.
+
+d.  Fixed a bug that caused `pwd' to not display anything in physical mode
+    when the file system had changed underneath the shell.
+
+e.  Fixed a bug in the pre- and post- increment and decrement parsing in the
+    expression evaluator that caused errors when the operands and corresponding
+    operators were separated by whitespace.
+
+f.  Fixed a bug that caused `history -p' to add an entry to the history list,
+    counter to the documentation.  (Keeps the history expansions invoked by
+    emacs-mode command line editing from doing that as well.)
+
+g.  Fixed a bug that could cause a core dump if `cd' is asked to print out a
+    pathname longer than PATH_MAX characters.
+
+h.  Fixed a bug that caused jobs to be put into the wrong process group under
+    some circumstances after enabling job control with `set -m'.
+
+i.  `unalias' now  returns failure if no alias name arguments are supplied.
+
+j.  Documented the characters not allowed to appear in an alias name.
+
+k.  $* is no longer expanded as if in double quotes when it appears in the
+    body of a here document, as the SUS seems to require.
+
+l.  The `bashbug' script now uses a directory in $TMPDIR for exclusive
+    access rather than trying to guess how the underlying OS provides for
+    secure temporary file creation.
+
+m.  Fixed a few problems with `cd' and `pwd' when asked to operate on pathnames
+    longer than PATH_MAX characters.
+
+n.  Fixed a memory leak caused when creating multiple local array variables
+    with identical names.
+
+o.  Fixed a problem with calls to getcwd() so that bash now operates better
+    when the full pathname to the current directory is longer than PATH_MAX
+    bytes.
+
+p.  The `trap' builtin now reports an error if a single non-signal argument
+    is specified.
+
+q.  Fixed a bug that caused `umask' to not work correctly when presented
+    with a mask of all 0s.
+
+r.  When `getopts' reaches the end of options, OPTARG is unset, as POSIX
+    appears to specify.
+
+s.  Interactive mode now depends on whether or not stdin and stderr are
+    connected to a tty; formerly it  was stdin and stdout.  POSIX requires
+    this.
+
+t.  Fixed vi-mode completion to work more as POSIX specifies (e.g., doing the
+    right kind of filename generation).
+
+2.  Changes to Readline
+
+a.  Fixed a problem that could cause readline to refer to freed memory when
+    moving between history lines while doing searches.
+
+b.  Improvements to the code that expands and displays prompt strings
+    containing multibyte characters.
+
+c.  Fixed a problem with vi-mode not correctly remembering the numeric argument
+    to the last `c'hange command for later use with `.'.
+
+d.  Fixed a bug in vi-mode that caused multi-digit count arguments to work
+    incorrectly.
+
+e.  Fixed a problem in vi-mode that caused the last text modification command
+    to not be remembered across different command lines.
+
+f.  Fixed problems with changing characters and changing case at the end of
+    the line.
+
+3.  New Features in Bash
+
+a.  The `jobs', `kill', and `wait' builtins now accept job control notation
+    even if job control is not enabled.
+
+b.  The historical behavior of `trap' that allows a missing `action' argument
+    to cause each specified signal's handling to be reset to its default is
+    now only supported when `trap' is given a single non-option argument.
+
+4.  New Features in Readline
+
+a.  When listing completions, directories have a `/' appended if the
+    `mark-directories' option has been enabled.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.0-beta1,
+and the previous version, bash-3.0-alpha.
+
+1.  Changes to Bash
+
+a.  Fixes to build correctly when arrays are not compiled into the shell.
+
+b.  Fixed command substitution to run any exit trap defined in the command
+    substitution before returning; the exit trap is not inherited from the
+    calling shell.
+
+c.  Fixes to process group synchronization code so that every child process
+    attempts to set the terminal's process group; fixes some synchronization
+    problems on Linux kernels that schedule the child to always run before
+    the parent.
+
+d.  Fixed processing of octal and hex constants in printf builtin for POSIX.2
+    compliance.
+
+e.  Fixed a couple of core dumps in the pattern removal code.
+
+f.  Fixes to the array subrange extraction code to deal better with sparse
+    arrays.
+
+g.  Parser errors and other errors that result in the shell exiting now cause
+    the exit trap to be run.
+
+h.  Change the command substitution completion functions to not append any
+    closing quote, because it would be inserted a closing "`" or ")".
+
+i.  Fix history initialization so assignments to $histchars made in startup
+    files are honored.
+
+j.  If an exit trap does not contain a call to `exit', the shell now uses
+    the exit status of the last command executed before the trap as the exit
+    status of the shell.
+
+k.  The parser now prompts with $PS2 if it reads a newline while parsing a
+    compound array assignment statement.
+
+l.  When performing a compound array assignment, the parser doesn't treat
+    words of the form [index]=value as assignments if they're the result of
+    expansions.
+
+m.  Fixed a bug that caused `return' executed in a trap command to make the
+    shell think it was still running the trap.
+
+n.  Fixed the value of errno set by the pathname canonicalization functions.
+
+o.  Changed the grammar so that `time' alone on a line times a null command
+    rather than being a syntax error.
+
+p.  The pattern substitution code no longer performs quote removal on the
+    pattern before trying to match it, as the pattern removal functions do.
+
+q.  Fixed a bug that could cause core dumps when checking whether a quoted
+    command name was being completed.
+
+r.  Fixes to the pattern removal and pattern replacement expansions to deal
+    with multibyte characters better (and faster).
+
+s.  Fix to the substring expansion (${param:off[:len]}) to deal with (possibly
+    multibyte) characters instead of raw bytes.
+
+t.  Fixed a bug that caused some key bindings set in an inputrc to be ignored
+    at shell startup.
+
+u.  Fixed a bug that caused unsetting a local variable within a function to
+    not work correctly.
+
+v.  Fixed a bug that caused invalid variables to be created when using
+    `read -a'.
+
+w.  Fixed a bug that caused "$@" to expand incorrectly when used as the right
+    hand side of a parameter expansion such as ${word:="$@"} if the first
+    character of $IFS was not a space.
+
+x.  Fixed a slight cosmetic problem when printing commands containing a
+    `>&word' redirection.
+
+y.  Fixed a problem that could cause here documents to not be created correctly
+    if the system temporary directory did not allow writing.
+
+2.  Changes to Readline
+
+a.  Change to history expansion functions to treat `^' as equivalent to word
+    one, as the documentation states.
+
+b.  Some changes to the display code to improve display and redisplay of
+    multibyte characters.
+
+c.  Changes to speed up the multibyte character redisplay code.
+
+d.  Fixed a bug in the vi-mode `E' command that caused it to skip over the
+    last character of a word if invoked while point was on the word's
+    next-to-last character.
+
+e.  Fixed a bug that could cause incorrect filename quoting when
+    case-insensitive completion was enabled and the word being completed
+    contained backslashes quoting word break characters.
+
+f.  Fixed a bug in redisplay triggered when the prompt string contains
+    invisible characters.
+
+g.  Fixed some display (and other) bugs encountered in multibyte locales
+    when a non-ascii character was the last character on a line.
+
+h.  Fixed some display bugs caused by multibyte characters in prompt strings.
+
+i.  Fixed a problem with history expansion caused by non-whitespace characters
+    used as history word delimiters.
+
+3.  New Features in Bash
+
+a.  printf builtin understands two new escape sequences:  \" and \?.
+
+b.  `echo -e' understands two new escape sequences:  \" and \?.
+
+c.  The GNU `gettext' package and libintl have been integrated; the shell's
+    messages can be translated into different languages.
+
+d.  The `\W' prompt expansion now abbreviates $HOME as `~', like `\w'.
+
+e.  The error message printed when bash cannot open a shell script supplied
+    as argument 1 now includes the name of the shell, to better identify
+    the error as coming from bash.
+
+4.  New Features in Readline
+
+a.  New application variable, rl_completion_quote_character, set to any
+    quote character readline finds before it calls the application completion
+    function.
+
+b.  New application variable, rl_completion_suppress_quote, settable by an
+    application completion function.  If set to non-zero, readline does not
+    attempt to append a closing quote to a completed word.
+
+c.  New application variable, rl_completion_found_quote, set to a non-zero
+    value if readline determines that the word to be completed is quoted.
+    Set before readline calls any application completion function.
+
+d.  New function hook, rl_completion_word_break_hook, called when readline
+    needs to break a line into words when completion is attempted.  Allows
+    the word break characters to vary based on position in the line.
+
+e.  New bindable command: unix-filename-rubout.  Does the same thing as
+    unix-word-rubout, but adds `/' to the set of word delimiters.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.0-alpha,
+and the previous version, bash-2.05b-release.
+
+1.  Changes to Bash
+
+a.  Fixes so that the shell will compile without some of the default options
+    defined.
+
+b.  Fixed an error message that did not pass enough arguments to printf.
+
+c.  Fixed a bug that caused input redirection to a builtin inside a script
+    being read from standard input to result in the rest of the already-
+    read and buffered script to be discarded.
+
+d.  Fixed a bug that caused subshell initialization to close the file
+    descriptor from which the shell was reading a script under certain
+    circumstances.
+
+e.  Fixed a bug that caused the shell to not advance a string pointer over
+    a null wide character when doing string operations.
+
+f.  Fixed the internal logout code so that shells that time out waiting for
+    input (using $TMOUT) run ~/.bash_logout.
+
+g.  Portability and configuration changes for: cygwin, HP/UX, GNU/FreeBSD.
+
+h.  The parser no longer adds implicit double quotes to ((...)) arithmetic
+    commands.
+
+i.  The ((...)) arithmetic command evaluation code was fixed to not dump core
+    when the expanded string is null.
+
+j.  The ((...)) arithmetic command evaluation code was fixed to not perform
+    variable assignments while expanding the expression.
+
+k.  Fixed a bug that caused word splitting to be performed incorrectly when
+    IFS is set, but null.
+
+l.  Fixed a bug in brace expansion that caused a quoted `$' preceding an
+    open brace to inhibit brace expansion.
+
+m.  Fixed a bug that caused a leading `-' in the shell's name to cause it to
+    not be recognized as a restricted shell.
+
+n.  Fixed a bug in the arithmetic evaluation code that could cause longjmps
+    to an invalid location and result in a core dump.
+
+o.  Fixed a bug in the calculation of how many history lines are new in a
+    single shell session when reading new history lines from a file with
+    `history -n'.
+
+p.  Fixed a bug in pathname canonicalization that caused the shell to dump
+    core when presented with a pathname longer than PATH_MAX.
+
+q.  Fixed the parser so that it doesn't try to compare a char variable to
+    EOF, which fails when chars are unsigned.
+
+r.  Fixed a bug in the simple command execution code that caused occasional
+    core dumps.
+
+s.  The shell does a better job of saving any partial parsing state during
+    operations which cause a command to be executed while a line is being
+    entered and parsed.
+
+t.  The completion code now splits words more like the expansion code when
+    $IFS is used to split.
+
+u.  The locale code does a better job of recomputing the various locale
+    variable values when LC_ALL is unset.
+
+v.  The programmable completion code does a better job of dequoting expanded
+    word lists before comparing them against the word to be matched.
+
+w.  The shell no longer seg faults if the expanded value of $PS4 is null
+    and `set -x' is enabled.
+
+x.  Fixed a bug that caused core dumps when a here string expanded to NULL.
+
+y.  The mail checking code now makes sure the mailbox is bigger before
+    reporting the existence of new mail.
+
+z.  The parser does not try to expand $'...' and $"..." when the appear
+    within double quotes unless the `extquote' option has been enabled with
+    `shopt'.  For backwards compatibility, it is enabled by default.
+
+aa. Fixed a bug that caused `for x; do ...' and `select x; do ... to use
+    $@ instead of "$@" for the implicit list of arguments.
+
+bb. Fixed a bug that caused a subshell of a restricted shell (e.g., one
+    spawned to execute a pipeline) to not exit immediately if attempting
+    to use a command containing a slash.
+
+cc. Fixed a problem with empty replacements for a pattern that doesn't match
+    when performing ${param/word/} expansion.
+
+dd. Word expansions performed while expanding redirections no longer search
+    a command's temporary environment to expand variable values.
+
+ee. Improvements to the alias expansion code when expanding subsequent words
+    because an aliase's value ends with a space.
+
+ff. `cd -' now prints the current working directory after a successful chdir
+    even when the shell is not interactive, as the standard requires.
+
+gg. The shell does a better job of ensuring a child process dies of SIGINT
+    before resending SIGINT to itself.
+
+hh. The arithmetic expansion variable assignment code now does the right
+    thing when assigning to `special' variables like OPTIND.
+
+ii. When history expansion verification is enabled, the bash readline helper
+    functions that do history expansion on the current line don't print
+    the results.
+
+jj. Fixed bugs with multiple consecutive alias expansion when one of the
+    expansions ends with a space.
+
+kk. Fixed a problem in the programmable completion code that could cause core
+    dumps when trying to initialize a set of possible completions from a
+    list of variables.
+
+ll. The \[ and \] escape characters are now ignored when decoding the prompt
+    string if the shell is started with editing disabled.
+
+mm. Fixed a bug that could leave extra characters in a string when doing
+    quoted null character removal.
+
+nn. Command substitution and other subshell operations no longer reset the
+    line number (aids the bash debugger).
+
+oo. Better line number management when executing simple commands, conditional
+    commands, for commands, and select commands.
+
+pp. The globbing code now uses malloc, with its better failure properties,
+    rather than alloca().
+
+qq. Fixed a bug that caused expansions like #{a[2]:=value} to create the
+    appropriate array element instead of a variable named `a[2]'.
+
+rr. Fixed a bug in the handling of a `?(...)' pattern immediately following
+    a `*' when extglob is enabled.
+
+ss. Fixed a bug that caused a `return' invoked in an exit trap when exit is
+    invoked in a function to misbehave.
+
+tt. Fixed a bug that caused CTLESC and CTLNUL characters to not be escaped
+    by the internal shell string quoting functions.
+
+uu. Fixed a bug that caused quoted null characters in an expanded word list
+    to be inappropriately assigned to an array variable when using `read -a'.
+
+vv. Fixed a bug that caused redirections accompanying a null command to persist
+    in the current shell.
+
+ww. Fixed a bug that caused the prompt to be printed when the shell was
+    expanding a multiline alias.
+
+xx. Fixed a bug that resulted in core dumps when the completion for a command
+    changed the compspec.
+
+yy. Fixed a bug that caused evaluation of programmable completions to print
+    notifications of completed jobs.
+
+zz. Bash now disables line editing when $EMACS == `t' and $TERM == `dumb'
+    (which is what emacs shell windows do).
+
+aaa. In posix mode, `kill -l' causes signal names to be displayed without
+     a leading `SIG'.
+
+bbb. Clear error flag on standard output so it doesn't persist across multiple
+     builtin commands.
+
+ccc. In posix mode, `alias' displays alias values without the leading `alias',
+     so the output cannot be used as subsequent input.
+
+ddd. In posix mode, the `trap' builtin doesn't check whether or not its
+     first argument is a signal specification and revert the signal handling
+     to its original disposition if it is.
+
+eee. Fixed several bugs in the handling of "$*" and "${array[*]}" by the
+     pattern substitution and removal expansions.
+
+fff. Fixed several problems with the handling of ${array[@]}, ${array[*]},
+     $@, and $* by the indirect variable expansion code.
+
+ggg. Fixed a bug that did not allow `time' to be aliased.
+
+hhh. Improved the mail checking code so it won't check (and possibly cause an
+     NFS file system mount) until MAILPATH or MAIL is given a value -- there
+     is no default if DEFAULT_MAIL_DIRECTORY is not defined at compile time.
+     (It is computed by configure, but can be #undef'd in config-bot.h.)
+
+iii. If the `chkwinsize' option is enabled, the shell checks for window size
+     changes if a child process exits due to a signal.
+
+jjj. Removed the attempts to avoid adding a slash at the end of a completed
+     executable name if there was a directory with the same name in the
+     current directory.
+
+kkk. Fixed PATH lookup code so it treats the permission bits separately for
+     owner, group, and other, rather than checking them all.
+
+lll. Fixed the locale code to reset the parser's idea of the character class
+     <blank>, which controls how it splits tokens, when the locale changes.
+
+mmm. The shell now binds its special readline functions and key bindings only
+     if the user's inputrc file has not already bound them.
+
+nnn. The shell now reports on processes that dump core due to signals when
+     invoked as `-c command'.
+
+2.  Changes to Readline
+
+a.  Fixes to avoid core dumps because of null pointer references in the
+    multibyte character code.
+
+b.  Fix to avoid infinite recursion caused by certain key combinations.
+
+c.  Fixed a bug that caused the vi-mode `last command' to be set incorrectly.
+
+d.  Readline no longer tries to read ahead more than one line of input, even
+    when more is available.
+
+e.  Fixed the code that adjusts the point to not mishandle null wide
+    characters.
+
+f.  Fixed a bug in the history expansion `g' modifier that caused it to skip
+    every other match.
+
+g.  Fixed a bug that caused the prompt to overwrite previous output when the
+    output doesn't contain a newline and the locale supports multibyte
+    characters.  This same change fixes the problem of readline redisplay
+    slowing down dramatically as the line gets longer in multibyte locales.
+
+h.  History traversal with arrow keys in vi insertion mode causes the cursor
+    to be placed at the end of the new line, like in emacs mode.
+
+i.  The locale initialization code does a better job of using the right
+    precedence and defaulting when checking the appropriate environment
+    variables.
+
+j.  Fixed the history word tokenizer to handle <( and >( better when used as
+    part of bash.
+
+k.  The overwrite mode code received several bug fixes to improve undo.
+
+l.  Many speedups to the multibyte character redisplay code.
+
+m.  The callback character reading interface should not hang waiting to read
+    keyboard input.
+
+n.  Fixed a bug with redoing vi-mode `s' command.
+
+o.  The code that initializes the terminal tracks changes made to the terminal
+    special characters with stty(1) (or equivalent), so that these changes
+    are reflected in the readline bindings.  New application-callable function
+    to make it work:  rl_tty_unset_default_bindings().
+
+p.  Fixed a bug that could cause garbage to be inserted in the buffer when
+    changing character case in vi mode when using a multibyte locale.
+
+q.  Fixed a bug in the redisplay code that caused problems on systems
+    supporting multibyte characters when moving between history lines when the
+    new line has more glyphs but fewer bytes.
+
+r.  Undo and redo now work better after exiting vi insertion mode.
+
+s.  Make sure system calls are restarted after a SIGWINCH is received using
+    SA_RESTART.
+
+t.  Improvements to the code that displays possible completions when using
+    multibyte characters.
+
+u.  Fixed a problem when parsing nested if statements in inputrc files.
+
+v.  The completer now takes multibyte characters into account when looking for
+    quoted substrings on which to perform completion.
+
+w.  The history search functions now perform better bounds checking on the
+    history list.
+
+3.  New Features in Bash
+
+a.  ANSI string expansion now implements the \x{hexdigits} escape.
+
+b.  There is a new loadable `strftime' builtin.
+
+c.  New variable, COMP_WORDBREAKS, which controls the readline completer's
+    idea of word break characters.
+
+d.  The `type' builtin no longer reports on aliases unless alias expansion
+    will actually be performed.    
+
+e.  HISTCONTROL is now a colon-separated list of values, which permits
+    more extensibility and backwards compatibility.
+
+f.  HISTCONTROL may now include the `erasedups' option, which causes all lines
+    matching a line being added to be removed from the history list.
+
+g.  `configure' has a new `--enable-multibyte' argument that permits multibyte
+    character support to be disabled even on systems that support it.
+
+h.  New variables to support the bash debugger:  BASH_ARGC, BASH_ARGV,
+    BASH_SOURCE, BASH_LINENO, BASH_SUBSHELL, BASH_EXECUTION_STRING,
+    BASH_COMMAND
+
+i.  FUNCNAME has been changed to support the debugger: it's now an array
+    variable.
+
+j.  for, case, select, arithmetic commands now keep line number information
+    for the debugger.
+
+k.  There is a new `RETURN' trap executed when a function or sourced script
+    returns (not inherited child processes; inherited by command substitution
+    if function tracing is enabled and the debugger is active).
+
+l.  New invocation option:  --debugger.  Enables debugging and turns on new
+    `extdebug' shell option.
+
+m.  New `functrace' and `errtrace' options to `set -o' cause DEBUG and ERR
+    traps, respectively, to be inherited by shell functions.  Equivalent to
+    `set -T' and `set -E' respectively.  The `functrace' option also controls
+    whether or not the DEBUG trap is inherited by sourced scripts.
+
+n.  The DEBUG trap is run before binding the variable and running the action
+    list in a `for' command, binding the selection variable and running the
+    query in a `select' command, and before attempting a match in a `case'
+    command.
+
+o.  New `--enable-debugger' option to `configure' to compile in the debugger
+    support code.
+
+p.  `declare -F' now prints out extra line number and source file information
+    if the `extdebug' option is set.
+
+q.  If `extdebug' is enabled, a non-zero return value from a DEBUG trap causes
+    the next command to be skipped, and a return value of 2 while in a
+    function or sourced script forces a `return'.
+
+r.  New `caller' builtin to provide a call stack for the bash debugger.
+
+s.  The DEBUG trap is run just before the first command in a function body is
+    executed, for the debugger.
+
+t.  `for', `select', and `case' command heads are printed when `set -x' is
+    enabled.
+
+u.  There is a new {x..y} brace expansion, which is shorthand for {x.x+1,
+    x+2,...,y}.  x and y can be integers or single characters; the sequence
+    may ascend or descend; the increment is always 1.
+
+v.  New ksh93-like ${!array[@]} expansion, expands to all the keys (indices)
+    of array.
+
+w.  New `force_fignore' shopt option; if enabled, suffixes specified by
+    FIGNORE cause words to be ignored when performing word completion even
+    if they're the only possibilities.
+
+x.  New `gnu_errfmt' shopt option; if enabled, error messages follow the `gnu
+    style' (filename:lineno:message) format.
+
+y.  New `-o bashdefault' option to complete and compgen; if set, causes the
+    whole set of bash completions to be performed if the compspec doesn't
+    result in a match.
+
+z.  New `-o plusdirs' option to complete and compgen; if set, causes directory
+    name completion to be performed and the results added to the rest of the
+    possible completions.
+
+aa. `kill' is available as a builtin even when the shell is built without
+    job control.
+
+bb. New HISTTIMEFORMAT variable; value is a format string to pass to
+    strftime(3).  If set and not null, the `history' builtin prints out
+    timestamp information according to the specified format when displaying
+    history entries.  If set, bash tells the history library to write out
+    timestamp information when the history file is written.
+
+cc. The [[ ... ]] command has a new binary `=~' operator that performs
+    extended regular expression (egrep-like) matching.
+
+dd. `configure' has a new `--enable-cond-regexp' option (enabled by default)
+    to enable the =~ operator and regexp matching in [[ ... ]].
+
+ee. Subexpressions matched by the =~ operator are placed in the new
+    BASH_REMATCH array variable.
+
+ff. New `failglob' option that causes an expansion error when pathname
+    expansion fails to produce a match.
+
+gg. New `set -o pipefail' option that causes a pipeline to return a failure
+    status if any of the processes in the pipeline fail, not just the last
+    one.
+
+4.  New Features in Readline
+
+a.  History expansion has a new `a' modifier equivalent to the `g' modifier
+    for compatibility with the BSD csh.
+
+b.  History expansion has a new `G' modifier equivalent to the BSD csh `g'
+    modifier, which performs a substitution once per word.
+
+c.  All non-incremental search operations may now undo the operation of
+    replacing the current line with the history line.
+
+d.  The text inserted by an `a' command in vi mode can be reinserted with
+    `.'.
+
+e.  New bindable variable, `show-all-if-unmodified'.  If set, the readline
+    completer will list possible completions immediately if there is more
+    than one completion and partial completion cannot be performed.
+
+f.  There is a new application-callable `free_history_entry()' function.
+
+g.  History list entries now contain timestamp information; the history file
+    functions know how to read and write timestamp information associated
+    with each entry.
+
+h.  Four new key binding functions have been added:
+
+	rl_bind_key_if_unbound()
+	rl_bind_key_if_unbound_in_map()
+	rl_bind_keyseq_if_unbound()
+	rl_bind_keyseq_if_unbound_in_map()
+

+
+1.  Changes to Bash
+
+a.  Fixed an off-by-one error in the function that translates job
+    specifications.
+
+b.  Note that we're running under Emacs and disable line editing if
+    $EMACS == `t'.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05b-beta2,
+and the previous version, bash-2.05b-beta1.
+
+1.  Changes to Bash
+
+a.  Fixed the /= and %= arithmetic operators to catch division by zero.
+
+b.  Added putenv, setenv, unsetenv to getenv replacement for completeness.
+
+c.  Fixed a bug that could cause the -O expand_aliases invocation option
+    to not take effect.
+
+d.  Fixed a problem with process substitution that resulted in incorrect
+    behavior when the number of process substitutions in an individual
+    command approached 64.
+
+2.  Changes to Readline
+
+a.  Fixed a problem with backward-char-search when on a system with support
+    for multibyte characters when running in a locale without any multibyte
+    characters.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05b-beta1,
+and the previous version, bash-2.05b-alpha1.
+
+1.  Changes to Bash
+
+a.  Fixed a problem when parsing a POSIX.2 character class name while
+    evaluating a bracket expression containing multibyte characters.
+
+b.  Changed the help text for `bind' to make it clear that any command
+    that may be placed in ~/.inputrc is a valid argument to `bind'.
+
+c.  Added `help' builtin entries for `((', `[[', and arithmetic for.
+
+d.  malloc updated again:
+	o slightly better overflow and underflow detection by putting the
+	  chunk size at the beginning and end of the chunk and making
+	  sure they match in free/realloc
+	o partial page allocated to make things page-aligned no longer
+	  completely wasted
+	o block coalescing now enabled by default
+	o splitting and coalescing enabled for 32-byte chunks, the most
+	  common size requested
+	o fixed a problem that resulted in spurious underflow messages and
+	  aborts
+	o bin sizes are precomputed and stored in an array rather than
+	  being computed at run time
+	o malloc will return memory blocks back to the system if the block
+	  being freed is at the top of the heap and of sufficient size to
+	  make it worthwhile
+	o malloc/free/realloc now inline memset instead of calling the
+	  libc function; uses Duff's device for good performance
+
+e.  Check for getservent(); make the service name completion code dependent
+    on its presence.
+
+f.  Changed the readline callback that executes a command bound to a key
+    sequence to not save the executed command on the history list and to
+    save and restore the parsing state.
+
+g.  Changes to lib/sh/snprintf.c:  fixed some bugs in the `g' and `G'
+    floating point format display; implemented the "'" flag character
+    that turns on thousands' grouping; fixed behavior on systems where
+    MB_CUR_MAX does not evaluate to a constant.
+
+h.  The `unset' builtin no longer returns a failure status when asked to
+    unset a previously-unset variable or function.
+
+i.  Changes to the build system to make it easier to cross-compile bash
+    for different systems.
+
+j.  Added `,' to  the characters that are backslash-escaped during filename
+    completion, to avoid problems with complete-into-braces and RCS filenames
+    containing commas.
+
+k.  Some changes to the multibyte character support code to avoid many calls
+    to strlen().
+
+l.  Bash now correctly honors setting LANG to some value when LC_ALL does not
+    already have a value.
+
+m.  Fixed a bug that could cause SIGSEGV when processing nested traps with
+    trap handlers.
+
+n.  The `source/.' builtin now restores the positional parameters when it
+    returns unless they were changed using the `set' builtin during the file's
+    execution.
+
+o.  Fixed a bug that caused a syntax error when a command was terminated by
+    EOF.
+
+2.  New Features in Bash
+
+a.  There is now support for placing the long help text into separate files
+    installed into ${datadir}/bash.  Not enabled by default; can be turned
+    on with `--enable-separate-helpfiles' option to configure.
+
+b.  All builtins that take operands accept a `--' pseudo-option, except
+    `echo'.
+
+c.  The `echo' builtin now accepts \0xxx (zero to three octal digits following
+    the `0') in addition to \xxx (one to three octal digits) for SUSv3/XPG6/
+    POSIX.1-2001 compliance.
+
+3.  Changes to Readline
+
+a.  Fixed a small problem in _rl_insert_char with multibyte characters.
+
+b.  Fixes from IBM for line wrapping problems when using multibyte characters.
+
+c.  Fixed a problem which caused the display to be messed up when the last
+    line of a multi-line prompt (possibly containing invisible characters)
+    was longer than the screen width.
+
+d.  Fixed a problem with the vi-mode `r' command that occurred on systems with
+    support for multibyte characters when running in a locale without any
+    multibyte characters.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05b-alpha1,
+and the previous version, bash-2.05a-release.
+
+1.  Changes to Bash
+
+a.  Some changes to work around inlining differences between compilers.
+
+b.  Added more prototypes for internal shell typedefs, to catch argument
+    passing errors when using pointers to functions.
+
+c.  The `cd' builtin now fails in posix mode when a valid directory cannot be
+    constructed from a relative pathname argument and the $PWD using pathname
+    canonicalization, and the -P option has not been supplied.  Previously,
+    the shell would attempt to use what the user typed, leading to weird
+    values for $PWD and discrepancies between the value of $PWD and the
+    actual working directory.
+
+d.  The `cd' builtin now resets $PWD when canonicalization fails but a chdir
+    to the pathname passed as an argument succeeds (when not in posix mode).
+
+e.  The `fc' builtin has been fixed, as POSIX requires, to use the closest
+    history position in range when given an out-of-range argument.
+
+f.  The history file loading code was changed to allow lines to be saved in
+    the history list from the shell startup files.
+
+g.  `history -s args' now works better in compound commands.
+
+h.  The tilde expansion code was fixed to better recognize when it's being
+    invoked in an assignment context, which enables expansion after `='
+    and `:'.
+
+i.  Fixed the command name completion code so a slash is no longer appended
+    to a single match if there happens to be a directory with that name in
+    $PWD.
+
+j.  Fixed compound array assignment to no longer perform alias expansion, to
+    allow reserved words as array members, and to not produce extra output
+    when the `-v' option had been enabled.
+
+k.  Fixed the programmable completion code to better handle newlines in lists
+    of possible completions (e.g., `complete -W').
+
+l.  Removed the reserved words from the `bash-builtins' manual page.
+
+m.  Parser error reporting now attempts to do a better job of identifying the
+    token in error rather than doing straight textual analysis.
+
+n.  Fixes for Inf/NaN, locales, wide/multibyte characters and zero-length
+    arguments in the library snprintf(3) replacement.
+
+o.  `read -e' no longer does command name completion on the first word on
+    the line being read.
+
+p.  `select' now returns failure if the read of the user's selection fails.
+
+q.  Fixed a bug that could cause a core dump when setting $PIPESTATUS.
+
+r.  Fixes to not allocate so many job slots when the shell is running a loop
+    with job control enabled in a subshell of an interactive shell.
+
+s.  Fixed a bug in the trap code that caused traps to be inherited by
+    command substitutions in some cases.
+
+t.  Fixed a bug that could cause alias expansion to inappropriately expand
+    the word following the alias.
+
+u.  Fixed a bug in the `kill' builtin that mishandled negative pid arguments.
+
+v.  The parser is less lenient when parsing assignment statements where the
+    characters before the `=' don't comprise a valid identifier.
+
+w.  The arithmetic expression evaluation code now honors the setting of the
+    `-u' option when expanding variable names.
+
+x.  Fixed the arithmetic evaluation code to allow array subscripts to be
+    assigned (`let b[7]=42') and auto-incremented and auto-decremented
+    (e.g., b[7]++).
+
+y.  Reimplemented the existing prompt string date and time expansions using
+    strftime(3), which changed the output of \@ in some locales.
+
+z.  Fixed a bug that could cause a core dump when a special shell variable
+    (like RANDOM) was converted to an array with a variable assignment.
+
+aa. Fixed a bug that would reset the handler for a signal the user had
+    trapped to a function that would exit the shell when setting the exit
+    trap in a non-interactive shell.
+
+bb. Changed the execve(2) wrapper code to check whether or not a failing
+    command is a directory before looking at whether a `#!' interpreter
+    failed for some reason.
+
+cc. Fixed a bug in the command printing code so it no longer inserts a `;'
+    after a newline, which produces a syntax error when reused as input.
+
+dd. The code that expands $PS4 no longer inherits the `-x' flag.
+
+ee. The bash-specific completion functions may now take advantage of the
+    double-TAB and M-?  features of the standard readline completion
+    functions.
+
+ff. The mail checking code no longer prints a message if the checked file's
+    size has not increased, even if the access time is less than the modification time.
+
+gg. Rewrote the variable symbol table code: there is now a stack of
+    contexts, each possibly including a separate symbol table; there can
+    be more than one temporary environment supplied to nested invocations
+    of `./source'; the temporary environments no longer require so much
+    special-case code; shell functions now handle the temporary environment
+    and local variables more consistently; function scope exit is faster now
+    that the entire symbol table does not have to be traversed to dispose of
+    local variables; it is now easier to push vars from the temporary
+    environment to the shell's variable table in posix mode; some duplicated
+    code has been removed.
+
+hh. Regularized the error message printing code; builtin_error is now called
+    more consistently, and common error message strings are handled by small
+    functions.  This should make eventual message translation easier.
+
+ii. Error messages now include the line number in a script when the shell
+    is not interactive.
+
+jj. Array subscript expansion now takes place even when the array variable is
+    unset, so side effects will take place.
+
+kk. Fixed a bug in the SICGHLD child-reaping code so that it won't find
+    jobs already marked as terminated if the OS reuses pids quickly enough.
+
+ll. Fixed a bug that could cause a signal to not interrupt the `wait'
+    builtin while it was waiting for a background process to terminate.
+
+mm. A couple of changes to make it easier for multiple shells to share history
+    files using `history -n', `history -r', and `history -w'.
+
+nn. The `getopts' builtin always increments OPTIND to point to the next
+    option to be handled when an option is returned, whether it's valid
+    or not, as POSIX 1003.x-2001 requires.
+
+oo. Changed some parts of the expansion code to avoid allocating and
+    immediately freeing memory without using the results for anything.
+
+pp. The shell now keeps track of $IFS internally, updating its internal map
+    each time the variable is assigned a new value (or at local scope exit).
+    This saves thousands of hash lookups for IFS, which, while individually
+    cheap, add up.
+
+qq. Rewrote the hash table code:  searching and insertion are much faster now,
+    and it uses a better string hashing function; augmented the function
+    interface to simplify other parts of the code and remove duplicated code
+
+rr. The shell now uses a simple, generic `object cache' for allocating and
+    caching words and word lists, which were the major users of
+    malloc/free.
+
+ss. Fixed the assignment statement parsing code to allow whitespace and
+    newlines in subscripts when performing array element assignment.
+
+tt. The shell now issues many fewer calls to sigprocmask and other signal
+    masking system calls.
+
+uu. Fixed the `test' and conditional command file comparison operators to
+    work right when one file has a non-positive timestamp and the other
+    does not exist.
+
+vv. Fixed some cases where the special characters '\001' and '\177' in the
+    values of variables or positional parameters caused incorrect expansion
+    results.
+
+2.  Changes to Readline
+
+a.  Fixed output of comment-begin character when listing variable values.
+
+b.  Added some default key bindings for common escape sequences produced by
+    HOME and END keys.
+
+c.  Fixed the mark handling code to be more emacs-compatible.
+
+d.  A bug was fixed in the code that prints possible completions to keep it
+    from printing empty strings in certain circumstances.
+
+e.  Change the key sequence printing code to print ESC as M\- if ESC is a
+    meta-prefix character -- it's easier for users to understand than \e.
+
+f.  Fixed unstifle_history() to return values that match the documentation.
+
+g.  Fixed the event loop (rl_event_hook) to handle the case where the input
+    file descriptor is invalidated.
+
+h.  Fixed the prompt display code to work better when the application has a
+    custom redisplay function.
+
+i.  Changes to make reading and writing the history file a little faster, and
+    to cope with huge history files without calling abort(3) from xmalloc.
+
+j.  The vi-mode `S' and `s' commands are now undone correctly.
+
+3.  New Features in Bash
+
+a.  If set, TMOUT is the default timeout for the `read' builtin.
+
+b.  `type' has two new options:  `-f' suppresses shell function lookup, and
+    `-P' forces a $PATH search.
+
+c.  New code to handle multibyte characters.
+
+d.  `select' was changed to be more ksh-compatible, in that the menu is
+    reprinted each time through the loop only if REPLY is set to NULL.
+    The previous behavior is available as a compile-time option.
+
+e.  `complete -d' and `complete -o dirnames' now force a slash to be
+    appended to names which are symlinks to directories.
+
+f.  There is now a bindable edit-and-execute-command readline command,
+    like the vi-mode `v' command, bound to C-xC-e in emacs mode.
+
+g.  Added support for ksh93-like [:word:] character class in pattern matching.
+
+h.  The  $'...' quoting construct now expands \cX to Control-X.
+
+i.  A new \D{...} prompt expansion; passes the `...' to strftime and inserts
+    the result into the expanded prompt.
+
+j.  The shell now performs arithmetic in the largest integer size the
+    machine supports (intmax_t), instead of long.
+
+k.  If a numeric argument is supplied to one of the bash globbing completion
+    functions, a `*' is appended to the word before expansion is attempted.
+
+l.  The bash globbing completion functions now allow completions to be listed
+    with double tabs or if `show-all-if-ambiguous' is set.
+
+m.  New `-o nospace' option for `complete' and `compgen' builtins; suppresses
+    readline's appending a space to the completed word.
+
+n.  New `here-string' redirection operator:  <<< word.
+
+o.  When displaying variables, function attributes and definitions are shown
+    separately, allowing them to be re-used as input (attempting to re-use
+    the old output would result in syntax errors).
+
+p.  There is a new configuration option `--enable-mem-scramble', controls
+    bash malloc behavior of writing garbage characters into memory at
+    allocation and free time.
+
+q.  The `complete' and `compgen' builtins now have a new `-s/-A service'
+    option to complete on names from /etc/services.
+
+r.  `read' has a new `-u fd' option to read from a specified file descriptor.
+
+s.  Fix the completion code so that expansion errors in a directory name
+    don't cause a longjmp back to the command loop.
+
+t.  Fixed word completion inside command substitution to work a little more
+    intuitively.
+
+u.  The `printf' %q format specifier now uses $'...' quoting to print the
+    argument if it contains non-printing characters.
+
+v.  The `declare' and `typeset' builtins have a new `-t' option.  When applied
+    to functions, it causes the DEBUG trap to be inherited by the named
+    function.  Currently has no effect on variables.
+
+w.  The DEBUG trap is now run *before* simple commands, ((...)) commands,
+    [[...]] conditional commands, and for ((...)) loops.
+
+x.  The expansion of $LINENO inside a shell function is only relative to the
+    function start if the shell is interactive -- if the shell is running a
+    script, $LINENO expands to the line number in the script.  This is as
+    POSIX-2001 requires.
+
+y.  The bash debugger in examples/bashdb has been modified to work with the
+    new DEBUG trap semantics, the command set has been made more gdb-like,
+    and the changes to $LINENO make debugging functions work better.  Code
+    from Gary Vaughan.
+
+z.  New [n]<&word- and [n]>&word- redirections from ksh93 -- move fds (dup
+    and close).
+
+aa. There is a new `-l' invocation option, equivalent to `--login'.
+
+bb. The `hash' builtin has a new `-l' option to list contents in a reusable
+    format, and a `-d' option to remove a name from the hash table.
+
+4.  New Features in Readline
+
+a.  Support for key `subsequences':  allows, e.g., ESC and ESC-a to both
+    be bound to readline functions.  Now the arrow keys may be used in vi
+    insert mode.
+
+b.  When listing completions, and the number of lines displayed is more than
+    the screen length, readline uses an internal pager to display the results.
+    This is controlled by the `page-completions' variable (default on).
+
+c.  New code to handle editing and displaying multibyte characters.
+
+d.  The behavior introduced in bash-2.05a of deciding whether or not to
+    append a slash to a completed name that is a symlink to a directory has
+    been made optional, controlled by the `mark-symlinked-directories'
+    variable (default is the 2.05a behavior).
+
+e.  The `insert-comment' command now acts as a toggle if given a numeric
+    argument:  if the first characters on the line don't specify a
+    comment, insert one; if they do, delete the comment text
+
+f.  New application-settable completion variable:
+    rl_completion_mark_symlink_dirs, allows an application's completion
+    function to temporarily override the user's preference for appending
+    slashes to names which are symlinks to directories.
+
+g.  New function available to application completion functions:
+    rl_completion_mode, to tell how the completion function was invoked
+    and decide which argument to supply to rl_complete_internal (to list
+    completions, etc.).
+
+h.  Readline now has an overwrite mode, toggled by the `overwrite-mode'
+    bindable command, which could be bound to `Insert'.
+
+i.  New application-settable completion variable:
+    rl_completion_suppress_append, inhibits appending of
+    rl_completion_append_character to completed words.
+
+j.  New key bindings when reading an incremental search string:  ^W yanks
+    the currently-matched word out of the current line into the search
+    string; ^Y yanks the rest of the current line into the search string,
+    DEL or ^H deletes characters from the search string.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05a-release,
+and the previous version, bash-2.05a-rc1.
+
+1.  Changes to Bash
+
+a.  Fixed the `printf' builtin so that the variable name supplied as an
+    argument to a %n conversion must be a valid shell identifier.
+
+b.  Improved the random number generator slightly.
+
+c.  Changes to configuration to not put -I/usr/include into $CFLAGS, since
+    it messes up some includes.
+
+d.  Corrected description of POSIXLY_CORRECT in man page and info manual.
+
+e.  Fixed a couple of cases of incorrect function prototypes that sneaked
+    through and caused compilation problems.
+
+f.  A few changes to avoid potential core dumps in the programmable completion
+    code.
+
+g.  Fixed a configure problem that could cause a non-existent file to show
+    up in LIBOBJS.
+
+h.  Fixed a configure problem that could cause siglist.o to not be built when
+    required.
+
+i.  Changes to the strtoimax and strtoumax replacement functions to work
+    around buggy compilers.
+
+j.  Fixed a problem with the snprintf replacement function that could
+    potentially cause a core dump.
+
+2.  Changes to Readline
+
+a.  Fixed a locale-specific problem in the vi-mode `goto mark' command.
+
+b.  Fixed Makefile to not put -I/usr/include into CFLAGS, since it can cause
+    include file problems.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05a-rc1,
+and the previous version, bash-2.05a-beta1.
+
+1.  Changes to Bash
+
+a.  Fixed the snprintf replacement to correctly implement the `alternate form'
+    of the %g and %G conversions.
+
+b.  Fixed snprintf to correctly handle the optional precision with the %g and
+    %G conversions.
+
+c.  Fixed the arithmetic evaluation code to correct the values of `@' and `_'
+    when translating base-64 constants (they were backwards).
+
+d.  New library functions for formatting long and long long ints.
+
+e.  Fixed a few places where negative array subscripts could have occurred,
+    mostly as the result of systems using signed characters.
+
+f.  Fixed a few places that assumed a pid_t was no wider than an int.
+
+g.  Fixed the `maildir' mail checking code to work on systems where a
+    `struct stat' doesn't include an `st_blocks' member.
+
+h.  Fixed snprintf to make `unsigned long long' conversion formats (%llu)
+    work better.
+
+i.  Fixed snprintf to not print a sign when asked to do an unsigned conversion.
+
+j.  Made configure changes to avoid compiling empty source files in lib/sh.
+
+k.  New replacement functions (if necessary) for strtoull, strtoll, strtoimax,
+    strtoumax.
+
+l.  The `printf' builtin now handles the `ll' and `j' length modifiers
+    directly, since they can affect the type and width of the argument
+    passed to printf(3).
+
+m.  Renamed a number of the bash-specific autoconf macros in aclocal.m4 to
+    have more systematic naming, with accompanying changes to configure.in.
+
+n.  Fixed snprintf to handle long doubles and the %a/%A conversions by
+    falling back to sprintf, as long as sprintf supports them.
+
+o.  Fixed return value from vsnprintf/snprintf to be the number of characters
+    that would have been printed, even if that number exceeds the buffer
+    size passed as an argument.
+
+p.  Bash no longer attempts to define its own versions of some ctype macros
+    if they are implemented as functions in libc but not as macros in
+    <ctype.h>.
+
+q.  Changed the variable printing code (used by `set', `export', etc.) to
+    not use the $'...' syntax when in posix mode, since that caused
+    interoperability problems with other shells (most notably with autoconf).
+    When not in posix mode, it uses $'...' if the string to be printed
+    contains non-printing characters and regular single quotes otherwise.
+
+r.  snprintf now recognizes the %F conversion.
+
+s.  Fixed a bug that could cause the wrong status to be returned by a shell
+    function when the shell is compiled without job control and a null
+    command containing a command substutition was executed in the function.
+
+t.  When in posix mode, the default value for MAILCHECK is 600.
+
+u.  Bash only initializes FUNCNAME, GROUPS, and DIRSTACK as special variables
+    if they're not in the initial environment.
+
+v.  If SECONDS appears in the initial environment with a valid integer value,
+    bash uses that as the starting value, as if an assignment had been
+    performed.
+
+w.  Bash no longer auto-exports HOME, PATH, SHELL, or TERM, even though it
+    gives them default values if they don't appear in the initial environment.
+
+x.  Bash no longer auto-exports HOSTNAME, HOSTTYPE, MACHTYPE, or OSTYPE,
+    even if it assigns them default values.
+
+y.  Bash no longer removes the export attribute from SSH_CLIENT or SSH2_CLIENT
+    if they appear in the initial environment.
+
+z.  Bash no longer attempts to discover if it's being run by sshd in order to
+    run the startup files.  If the SSH_SOURCE_BASHRC is uncommented in
+    config-top.h it will attempt to do so as previously, but that's commented
+    out in the distributed version.
+
+aa. Fixed a typo in the code that tests for LC_NUMERIC.
+
+bb. The POSIXLY_CORRECT shell variable and its effects are now documented.
+
+cc. Some changes to several of the support shell scripts included in the
+    definitions to try to avoid race conditions and attacks.
+
+dd. Several changes to avoid warnings from `gcc -Wall'.
+
+ee. Fixed a problem with the `unset' builtin that could cause incorrect
+    results if asked to unset a variable and an array subscript in the
+    same command.
+
+ff. A few changes to the shell's temporary file creation code to avoid
+    potential file descriptor leaks and to prefer the system's idea of
+    the temporary directory to use.
+
+gg. Fixes to build with the C alloca in lib/malloc/alloca.c if the system
+    requires it but the shell has been configured --without-bash-malloc.
+
+hh. Updated the documentation to note that only interactive shells resend
+    SIGHUP to all jobs before exiting.
+
+ii. Fixes to only pass unquoted tilde words to tilde_expand, rather than
+    rely on tilde_expand or getpwnam(3) to handle the quotes (MacOS 10.x
+    will remove backslashes in any login name passed to getpwnam(3)).
+
+jj. Small change from Paul Eggert to make LINENO right in commands run with
+    `bash -c'.
+
+2.  New Features in Bash
+
+a.  The `printf' builtin now handles the %a and %A conversions if they're
+    implemented by printf(3).
+
+b.  The `printf' builtin now handles the %F conversion (just about like %f).
+
+c.  The `printf' builtin now handles the %n conversion like printf(3).  The
+    corresponding argument is the name of a shell variable to which the
+    value is assigned.
+
+3.  Changes to Readline
+
+a.  Fixed a few places where negative array subscripts could have occurred.
+
+b.  Fixed the vi-mode code to use a better method to determine the bounds of
+    the array used to hold the marks.
+
+c.  Fixed the defines in chardefs.h to work better when chars are signed.
+
+d.  Fixed configure.in to use the new names for bash autoconf macros.
+
+e.  Readline no longer attempts to define its own versions of some ctype
+    macros if they are implemented as functions in libc but not as macros in
+    <ctype.h>.
+
+f.  Fixed a problem where rl_backward could possibly set point to before
+    the beginning of the line.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05a-beta1,
+and the previous version, bash-2.05a-alpha1.
+
+1.  Changes to Bash
+
+a.  Fixed a bug in the evaluation of arithmetic `for' statements when the
+    expanded expression is NULL.
+
+b.  Fixed an unassigned variable problem in the redirection printing code.
+
+c.  Added more prototypes to extern function declarations in the header
+    files and to static function declarations in C source files.
+
+d.  Make sure called functions have a prototype in scope, to get the arguments
+    and return values right instead of casting.  Removed extern function
+    declarations from C source files that were already included in header
+    files.
+
+e.  Changed some function arguments to use function typedefs in general.h so
+    the prototypes can be checked.  The only use of Function and VFunction
+    now is for unwind-protects.
+
+f.  More const changes to function arguments and appropriate variables.
+
+g.  Changed the mail checking support to handle `maildir'-style mail
+    directories.
+
+h.  Augmented the bash malloc to pass in the file and line number information
+    for each malloc, realloc, and free.  This should result in better error
+    messages.
+
+i.  The `old' gnu malloc is no longer a configuration option.
+
+j.  Augmented the bash malloc with optional tracing and registering allocated
+    and freed memory.
+
+k.  Prompt string decoding now saves and restores the value of $? when it
+    expands the prompt string, so command substitutions don't change $?.
+
+i.  Array indices are now `long', since shell arithmetic is performed as long,
+    and the internal arrayind_t type is used consistently.
+
+j.  Some more `unsigned char *' fixes from Paul Eggert.
+
+k.  Fixed a bad call to builtin_error that could cause core dumps when making
+    local variables.
+
+l.  `return' may no longer be used to terminate a `select' command, for
+    compatibility with ksh.
+
+m.  Changed code that reads octal numbers to do a better job of detecting
+    overflows.
+
+n.  The time formatting code no longer uses absolute indices into a buffer,
+    because the buffer size changes depending on the size of a `time_t'.
+
+o.  `umask' now prints four digits when printing in octal mode, for
+    compatibility with other shells.
+
+p.  Lots of changes to the `printf' builtin from Paul Eggert:  it handles `L'
+    formats and long doubles better, and internal functions have been
+    simplified where appropriate.
+
+q.  Some `time_t' fixes for machines were a time_t is bigger than a long.
+
+r.  Replaced some bash-specific autoconf macros with standard equivalents.
+
+s.  Improvmed the code that constructs temporary filenames to make the
+    generated names a bit more random.
+
+t.  Added code that checks for ascii before calling any of the is* ctype
+    functions.
+
+u.  Changed some places where a `char' was used as an array subscript to use
+    `unsigned char', since a `char' can be negative if it's signed by default.
+
+v.  Lots of changes to the `ulimit' builtin from Paul Eggert to add support
+    for the new POSIX-200x RLIM_SAVED_CUR and RLIM_SAVED_MAX values and
+    simplify the code.
+
+w.  `ulimit' now prints the description of a resource in any error message
+    relating to fetching or setting that resource's limits.
+
+x.  The `snprintf' replacement now computes maximum values at compile
+    time rather than using huge constants for things like long long.
+
+y.  Interactive shells now ignore `set -n'.
+
+z.  Changed the malloc bookkeeping information so that it's now 8 bytes
+    instead of 12 on most 32-bit machines (saving 4 bytes per allocation),
+    restoring 8-byte alignment.
+
+aa. The malloc error reporting code now attempts to print the file and line
+    number of the call that caused the error.
+
+bb. Changed the redirection error reporting code to catch EBADF errors and
+    report the file descriptor number rather than the file being redirected
+    to or from (e.g., things like `exec 4242<x' where 4242 is an out-of-range
+    file descriptor).
+
+cc. `printf', `echo -e', and the $'...' code now process only two hex digits
+    after a `\x' escape sequence for compatibility with other shells, and
+    the documentation was changed to note that the octal and hex escape
+    sequences result in an eight-bit value rather than strict ASCII.
+
+2.  Changes to Readline
+
+a.  The completion code now attempts to do a better job of preserving the
+    case of the word the user typed if ignoring case in completions.
+
+b.  Readline defaults to not echoing the input and lets the terminal
+    initialization code enable echoing if there is a controlling terminal.
+
+c.  The key binding code now processes only two hex digits after a `\x'
+    escape sequence, and the documentation was changed to note that the
+    octal and hex escape sequences result in an eight-bit value rather
+    than strict ASCII.
+
+3.  New Features in Bash
+
+a.  The builtin `ulimit' now takes two new non-numeric arguments:  `hard',
+    meaning the current hard limit, and `soft', meaning the current soft
+    limit, in addition to `unlimited'
+
+b.  `ulimit' now prints the option letter associated with a particular
+    resource when printing more than one limit.
+
+c.  `ulimit' prints `hard' or `soft' when a value is not `unlimited' but is
+    one of RLIM_SAVED_MAX or RLIM_SAVED_CUR, respectively.
+
+4.  New Features in Readline
+
+a.  New bindable variable `history-preserve-point'.  If set, the history
+    code attempts to place the user at the same location on each history
+    line retrieved with previous-history or next-history.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05a-alpha1,
+and the previous version, bash-2.05-release.
+
+1.  Changes to Bash
+
+a.  Better checks in the redirection code for write errors.
+
+b.  bashbug now uses $TMPDIR, defaulting to /tmp, and uses mktemp(1) more
+    portably.
+
+c.  System-specific configuration changes for:  Interix, OpenBSD, FreeBSD,
+    MacOS X.
+
+d.  Some more `const' cleanups through the code.
+
+e.  Fixed a typo in the /dev/fd redirection code, better checks for valid
+    numeric fds in /dev/fd.
+
+f.  Fixed many parts of the shell to handle integer overflow more gracefully
+    and to do more stringent checks for valid numbers.
+
+g.  Fixed mksignames to include config.h.
+
+h.  Fixed an uninitialized variable problem that could cause the shell to core
+    dump when replacing characters in a string.
+
+i.  New mechanism for updating the patch level when official patches are
+    released (patchlevel.h).
+
+j.  configure.in changed to no longer require external files _distribution and
+    _patchlevel.
+
+k.  Fixed non-interactive shell initialization problem when bash started as
+    `bash -i filename'.
+
+l.  Fixed printf builtin conversion error handling to be POSIX.2-conformant.
+
+m.  autoconf-2.52 is now used to build configure; autoconf-2.50 or newer is
+    required.  Some of the bash-specific macros were removed, since they are
+    now standard.
+
+n.  Startup files and files read with source or `.' are no longer required to
+    be regular files.
+
+o.  Fixed core dump in builtin printf when user-supplied precision or field
+    width is 0.
+
+p.  Fixed builtin printf to treat a negative field width as a positive field
+    width with left-justification.
+
+r.  New unwind-protect implementation from Paul Eggert.
+
+s.  Fixed an inadvertently-unclosed comment in the bash completion code that
+    caused programmable completions to not add trailing slashes or spaces to
+    completions.
+
+t.  Fixed the process substitution code to cope better when stdin is closed.
+
+v.  Fixes, mostly from Paul Eggert, for a few possible buffer overflows in
+    the shell.
+
+w.  Fixes from Paul Eggert to avoid most of the type casts in the shell code,
+    and use more appropriate types for a number of variables.
+
+x.  Command substitution no longer inherits the DEBUG trap.
+
+y.  Some fixes to the process substitution code on machines without /dev/fd so
+    that named pipes are not removed inappropriately.
+
+z.  The loadable `getconf' builtin is now much more complete, and will become
+    part of the shell in the future.
+
+aa. The select command no longer terminates on a `return', so it can be used
+    to return from an enclosing function (as ksh does it).
+
+bb. Fixed the extended pattern matching code to behave better when presented
+    with incorrectly-formed patterns.
+
+cc. Some changes were made with the intent of making cross-compilation easier.
+
+dd. The network code (/dev/tcp and /dev/udp redirections) uses getaddrinfo(3)
+    if it's available, which adds support for IPv6.
+
+ee. Subshells of login shells no longer source ~/.bash_logout when they exit.
+
+ff. Fixes so that subshells don't exit inappropriately if the -e option has
+    been set.
+
+gg. Restricted shells no longer allow functions to be exported.
+
+hh. Changes to the pattern matching code so extended pattern matching works
+    on systems with deficient shared library implementations, like MacOS X.
+
+ii. Better error messages when a script with a leading `#!interp' fails
+    to execute because of problems with `interp'.
+
+jj. Fixed `compgen' to handle the `-o default' option better.
+
+kk. Fixed the job control code to force an asynchronous process's standard
+    input to /dev/null only if job control is not active.
+
+ll. Fixed a possible infinite recursion problem when `fc ""=abc' (a null
+    pattern) is used to re-execute a previous command.
+
+mm. Fixed `declare [-a] var=value' to assign VALUE to element 0 if VAR is an
+    array variable.  Similarly for `declare [-a] var[N]=value'.  This is like
+    ksh93.
+
+nn. Fixed a bug that caused `read -a aname' to work even if ANAME had been
+    declared readonly.
+
+oo. Fixed a possible integer overflow problem when constructing names for
+    temporary files.
+
+2.  New Features in Bash
+
+a.  Added support for DESTDIR installation root prefix, so you can do a
+    `make install DESTDIR=bash-root' and do easier binary packaging.
+
+b.  Added support for builtin printf "'" flag character as per latest POSIX
+    drafts.
+
+c.  Support for POSIX.2 printf(1) length specifiers `j', `t', and `z' (from
+    ISO C99).
+
+d.  New autoconf macro, RL_LIB_READLINE_VERSION, for use by other applications
+    (bash doesn't use very much of what it returns).
+
+e.  `set [-+]o nolog' is recognized as required by the latest POSIX drafts,
+    but ignored.
+
+f.  New read-only `shopt' option:  login_shell.  Set to non-zero value if the
+    shell is a login shell.
+
+g.  New `\A' prompt string escape sequence; expands to time in 24 HH:MM format.
+
+h.  New `-A group/-g' option to complete and compgen; does group name
+    completion.
+
+i.  New `-t' option to `hash' to list hash values for each filename argument.
+
+j.  New [-+]O invocation option to set and unset `shopt' options at startup.
+
+k.  configure's `--with-installed-readline' option now takes an optional
+    `=PATH' suffix to set the root of the tree where readline is installed
+    to PATH.
+
+l.  The ksh-like `ERR' trap has been added.  The `ERR' trap will be run
+    whenever the shell would have exited if the -e option were enabled.
+    It is not inherited by shell functions.
+
+m.  `readonly', `export', and `declare' now print variables which have been
+    given attributes but not set by assigning a value as just a command and
+    a variable name (like `export foo') when listing, as the latest POSIX
+    drafts require.
+
+n.  `bashbug' now requires that the subject be changed from the default.
+
+o.  configure has a new `--enable-largefile' option, like other GNU utilities.
+
+p.  `for' loops now allow empty word lists after `in', like the latest POSIX
+    drafts require.
+
+3.  Changes to Readline
+
+a.  More `const' and type casting fixes.
+
+b.  Changed rl_message() to use vsnprintf(3) (if available) to fix buffer
+    overflow problems.
+
+c.  The completion code no longer appends a `/' or ` ' to a match when
+    completing a symbolic link that resolves to a directory name, unless
+    the match does not add anything to the word being completed.  This
+    means that a tab will complete the word up to the full name, but not
+    add anything, and a subsequent tab will add a slash.
+
+d.  Fixed a trivial typo that made the vi-mode `dT' command not work.
+
+e.  Fixed the tty code so that ^S and ^Q can be inserted with rl_quoted_insert.
+
+f.  Fixed the tty code so that ^V works more than once.
+
+g.  Changed the use of __P((...)) for function prototypes to PARAMS((...))
+    because the use of __P in typedefs conflicted g++ and glibc.
+
+4.  New Features in Readline
+
+a.  Added extern declaration for rl_get_termcap to readline.h, making it a
+    public function (it was always there, just not in readline.h).
+
+b.  New #defines in readline.h:  RL_READLINE_VERSION, currently 0x0402,
+    RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2.
+
+c.  New readline variable:  rl_readline_version, mirrors RL_READLINE_VERSION.
+
+d.  New bindable boolean readline variable:  match-hidden-files.  Controls
+    completion of files beginning with a `.' (on Unix).  Enabled by default.
+
+e.  The history expansion code now allows any character to terminate a
+    `:first-' modifier, like csh.
+
+f.  The incremental search code remembers the last search string and uses
+    it if ^R^R is typed without a search string.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05-release,
+and the previous version, bash-2.05-beta2.
+
+1.  Changes to Bash
+
+a.  Make sure we note that the first line of a multi-line command was not
+    saved in the history if the tests for HISTCONTROL succeed, but the
+    HISTIGNORE check fails.
+
+b.  Fixed a bug in the pattern matching code that caused `[' to be treated
+    as a special character inside a `[...]' bracket expression.
+
+c.  Fixed a bug in the pattern matching code that caused `]' to terminate
+    a bracket expression even if it was the first character after the `['
+    (or a leading `!' or `^').
+
+d.  Made a small change to report a more user-friendly error message if
+    execve(2) fails because of an error with the interpreter in a script
+    with a leading `#! interpreter'.
+
+e.  If the OS does not support an exec(2) magic number of `#!', make sure we
+    have a non-null interpreter name before attempting to execute it.
+
+f.  Fixed a bug that caused the shell process to end up in a different
+    process group than the controlling terminal if a job-control shell was
+    run with `exec' in the startup files.
+
+g.  When started in POSIX mode, either by `bash --posix', `bash -o posix', or
+    `sh', $SHELLOPTS includes `posix' and POSIXLY_CORRECT is set.
+
+h.  Fixed a problem that caused the `\W' prompt string escape sequence to
+    expand to nothing when $PWD was `//'.
+
+i.  The `bashbug' shell script no longer uses $(...) command substitution.
+
+j.  When `set' is invoked without options in POSIX mode, it no longer prints
+    the names and definitions of shell functions.
+
+2.  Changes to Readline
+
+a.  rl_set_paren_blink_timeout() is now documented.
+
+b.  Corrected history.3 man page: `$' is not in the default value of
+    history_word_delimiters.
+
+c.  If a hook function assigned to rl_event_hook sets rl_done to a non-zero
+    value, rl_read_key() now immediately returns '\n' (which is assumed to
+    be bound to accept-line).
+
+3.  New Features in Bash
+
+a.  The `>&word' redirection now works in POSIX mode as it does by default,
+    since POSIX.2 leaves it unspecified.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05-beta2,
+and the previous version, bash-2.05-beta1.
+
+1.  Changes to Bash
+
+a.  Fixed a bug in the arithmetic evaluation code so that a^=b is supported.
+
+b.  Fixed startup so posixly_correct is retained across subshells begun to
+    execute scripts without a leading `#!'.
+
+c.  Fixed a bug that caused $(< file) to not work in a (...) subshell.
+
+d.  Added config support for Linux running on the IBM S390.
+
+e.  Fixed a bug that caused bash to get its input pointer out of sync when
+    reading commands through a pipe and running a command with standard
+    input redirected from a file.
+
+f.  Made a change so that command completion now makes about half as many
+    stat(2) calls when searching the $PATH.
+
+g.  Fixed a bug that caused variable assignments preceding `return' to not
+    be propagated to the shell environment in POSIX mode.
+
+h.  Fixed a bug with ${parameter[:]?word} -- tilde expansion was not performed
+    on `word'.
+
+i.  In POSIX mode, `break' and `continue' do not complain and return success
+    if called when the shell is not executing a loop.
+
+j.  Fixed `bash -o posix' to work the same as `bash --posix'.
+
+k.  Fixed a bug where variable assignments preceding `eval' or `source/.'
+    would not show up in the environment exported to subshells run by the
+    commands.
+
+l.  In POSIX mode, shells started to execute command substitutions inherit
+    the value of the `-e' option from their parent shell.
+
+m.  In POSIX mode, aliases are expanded even in non-interactive shells.
+
+n.  Changed some of the job control messages to display the text required by
+    POSIX.2 when the shell is in POSIX mode.
+
+o.  Fixed a bug in `test' that caused it to occasionally return incorrect
+    results when non-numeric arguments were supplied to `-t'.
+
+2.  Changes to Readline
+
+a.  Some changes were made to avoid gcc warnings with -Wall.
+
+b.  rl_get_keymap_by_name now finds keymaps case-insensitively, so
+    `set keymap EMACS' works.
+
+c.  The history file writing and truncation functions now return a useful
+    status on error.
+
+d.  Fixed a bug that could cause applications to dereference a NULL pointer
+    if a NULL second argument was passed to history_expand().
+
+3.  New Features in Bash
+
+a.  doc/readline.3 has been moved to the readline distribution.
+
+4.  New Features in Readline
+
+a.  New function, rl_get_screen_size (int *rows, int *columns), returns
+    readline's idea of the screen dimensions.
+
+b.  The timeout in rl_gather_tyi (readline keyboard input polling function)
+    is now settable via a function (rl_set_keyboard_input_timeout()).
+
+c.  Renamed the max_input_history variable to history_max_entries; the old
+    variable is maintained for backwards compatibility.
+
+d.  The list of characters that separate words for the history tokenizer is
+    now settable with a variable:  history_word_delimiters.  The default
+    value is as before.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05-beta1,
+and the previous version, bash-2.05-alpha1.
+
+1.  Changes to Bash
+
+a.  Changes to allow shared library and object building on the GNU Hurd.
+
+b.  Fixes to the way exported functions are placed into the environment and
+    cached.
+
+c.  The globbing library once again respects locales when processing ranges
+    in bracket expressions while doing pattern matching.
+
+d.  System-specific configuration changes for:  Tru 64, Interix
+
+e.  Bashbug now uses /usr/bin/editor as one of the editing alternatives, and
+    will use mktemp(1) or tempfile(1), if present, for temporary file creation.
+
+f.  Bash no longer performs a binary file check on a script argument that's
+    really a tty (like /dev/fd/0 or /dev/stdin).
+
+g.  Fixed a bug in the execution of shell scripts that caused the effects of
+    $BASH_ENV to be undone in some cases.
+
+h.  Fixed several bugs that made `bash [-i] /dev/stdin' not work correctly.
+
+i.  Several changes to the job control code to avoid some signal state
+    manipulation.
+
+j.  The Bash malloc no longer blocks signals as often, which should make it
+    faster.
+
+k.  Fixed a parsing bug that did not allow backslash to escape a single quote
+    inside a $'...' construct.
+
+l.  Fixed a bug that caused things like ${var:=$'value'} to be parsed
+    incorrectly.  This showed up in newer versions of autoconf.
+
+m.  Fixed a bug in the bash-specific readline initialization that caused
+    key bindings to bash-specific function names appearing in .inputrc to
+    not be honored.
+
+n.  Bash now sets the file descriptor it uses to save the file descriptor
+    opened on a shell script to close on exec.
+
+o.  Fixed a bug in the prompt string decoding that caused it to misbehave
+    when presented an octal sequence of fewer than three characters.
+
+p.  Fixed the `test' builtin to return an error if `[' is supplied a single
+    argument that is not `]'.
+
+q.  Fixed a bug that caused subshells started to run executable shell scripts
+    without a leading `#!' to incorrectly inherit an argument list preceding
+    a shell builtin (like such a script called from a script sourced with `.',
+    where there were variable assignments preceding the `.' command)
+
+r.  Fixed a bug that caused changes to variables supplied in an assignment
+    statement preceding a shell builtin to not be honored (like a script
+    run with `.').
+
+s.  HOSTTYPE, OSTYPE, and MACHTYPE are set only if they do not have values
+    when the shell is started.
+
+t.  Fixed a bug that caused SIGINT to kill shell scripts after the script
+    called `wait'.
+
+u.  The `fc' builtin now tries to create its temporary files in the directory
+    named by $TMPDIR.
+
+v.  Bash no longer calls any Readline functions or uses any Readline variables
+    not declared in readline.h.
+
+w.  Fixed a bug that caused some substitutions involving $@ to not be split
+    correctly, especially expansions of the form ${paramterOPword}.
+
+x.  SSH2_CLIENT is now treated like SSH_CLIENT and not auto-exported if it
+    appears in the initial environment.
+
+y.  Fixed a couple of problems with shell scripts without a leading `#!'
+    being executed out of shell functions that could cause core dumps if
+    such a script attempted to execute `return'.
+
+z.  Fixed a problem with the `-nt' and `-ot' binary operators for the
+    `test/[' builtin and the `[[' conditional command that caused wrong
+    return values if one of the file arguments did not exist.
+
+aa. Fixed a bug that caused non-interactive shells which had previously
+    executed `shopt -s expand_aliases' to fail to expand aliases in a
+    command like `(command) &'.
+ 
+2.  Changes to Readline
+
+a.  Changes to make most (but not yet all -- there is still crlf()) of the
+    exported readline functions declared in readline.h have an rl_ prefix.
+
+b.  More `const' changes in function arguments, mostly for completion
+    functions.
+
+c.  Fixed a bug in rl_forward that could cause the point to be set to before
+    the beginning of the line in vi mode.
+
+d.  Fixed a bug in the callback read-char interface to make it work when a
+    readline function pushes some input onto the input stream with
+    rl_execute_next (like the incremental search functions).
+
+e.  Fixed a file descriptor leak in the history file manipulation code that
+    was tripped when attempting to truncate a non-regular file (like
+    /dev/null).
+
+f.  Some existing variables are now documented and part of the public
+    interface (declared in readline.h):  rl_explict_arg, rl_numeric_arg,
+    rl_editing_mode, rl_last_func.
+
+g.  Renamed rltty_set_default_bindings to rl_tty_set_default_bindings and
+    crlf to rl_crlf, so there are no public functions declared in readline.h
+    without an `rl_' prefix.  The old functions still exist for backwards
+    compatibility.
+
+3.  New Features in Bash
+
+a.  A new loadable builtin, realpath, which canonicalizes and expands symlinks
+    in pathname arguments.
+
+b.  When `set' is called without options, it prints function definitions in a
+    way that allows them to be reused as input.  This affects `declare' and
+    `declare -p' as well.
+
+4.  New Features in Readline
+
+a.  New application-callable function rl_set_prompt(const char *prompt):
+    expands its prompt string argument and sets rl_prompt to the result.
+
+b.  New application-callable function rl_set_screen_size(int rows, int cols):
+    public method for applications to set readline's idea of the screen
+    dimensions.
+
+c.  The history example program (examples/histexamp.c) is now built as one
+    of the examples.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05-alpha1,
+and the previous version, bash-2.04-release.
+
+1.  Changes to Bash
+
+a.  A fix was made to allow newlines in compond array assignments.
+
+b.  configure now checks for real-time signals with unusable values.
+
+c.  Interactive shells no longer exit if a substitution fails because of an
+    unset variable within a sourced file.
+
+d.  Fixed a problem with incorrect matching of extended glob patterns when
+    doing pattern substitution.
+
+e.  `{' is now quoted by the completion code when it appears in a filename.
+
+f.  Fixed an error in pattern matching that caused the matcher to not
+    correctly skip the rest of a bracket expression after a character
+    matched.
+
+g.  Fixed a bug in the IFS word splitting code to make a non-whitespace IFS
+    character preceded by IFS whitespace part of the current delimiter rather
+    than generating a separate field.
+
+h.  The {!prefix@} expansion now generates separate words, analogous to $@,
+    when double-quoted.
+
+i.  Command substitution now ignores NUL bytes in the command output, and the
+    parser ignores them on input.
+
+j.  A fix was made to the job control code to prevent hanging processes when
+    the shell thinks background processes are running but the kernel returns
+    -1/ECHILD from waitpid().
+
+k.  `pwd' now prints an error message if the write fails when displaying the
+    current directory.
+
+l.  When in POSIX mode, the shell prints trap dispostions without a leading
+    `SIG' in the signal specification.
+
+m.  Fixed a parser bug that caused the current command's line count to be
+    messed up by a compound array assignment.
+
+n.  Fixed a bug in the unwind-protect code that caused bad behavior on machines
+    where ints and pointers are not the same size.
+
+o.  System-specific configure changes for:  MacOS X.
+
+p.  Changes for Cygwin to translate \r\n and \r to \n and to set file
+    descriptors used for reading input to text mode in various places.
+
+q.  Fixed a bug that caused `!' to occasionally not be honored when in
+    a (...) subshell.
+
+r.  Bash no longer assumes that getcwd() will return any useful error message
+    in the buffer passed as an argument if the call fails.
+
+s.  The `source', `.', and `fc' builtins no longer check whether a file is
+    binary before reading commands from it.
+
+t.  Subshells no longer turn off job control when they exit, since that
+    sometimes resulted in the terminal being reset to the wrong process
+    group.
+
+u.  The history code no longer tries to save the second and subsequent lines
+    of a multi-line command if the first line was not saved.
+
+v.  The history saving code now does a better job of saving blank lines in a
+    multi-line command.
+
+w.  Removed a `feature' that made `ulimit' silently translate `unlimited' to
+    the current hard limit, which obscured some kernel error returns.
+
+x.  Fixed the grammar so that `}' is recognized as a reserved word after
+    another reserved word, rather than requiring a `;' or newline.  This
+    means that constructs like
+
+	{ { echo a b c ; } }
+
+    work as expected.
+
+y.  Conditional commands ([[...]]) now perform tilde expansion on their
+    arguments.
+
+z.  Noted in the documentation that `set -a' will cause functions to be
+    exported if they are defined after `set -a' is executed.
+
+aa. When an interactive login shell starts, if $PWD and $HOME refer to the
+    same directory but are not the same string, $PWD is set to $HOME.
+
+bb. Fixed `printf' to handle invalid floating point numbers better.
+
+cc. Temporary files are now created with random filenames, to improve security.
+
+dd. The readline initialization code now binds the custom bash functions and
+    key bindings after the readline defaults are set up.
+
+ee. Fixed the `source' builtin to no longer overwrite a shell function's
+    argument list, even if the sourced file changes the positional parameters.
+
+ff. A bug fix was made in the expansion of `$*' in contexts where it should
+    not be split, like assignment statements.
+
+gg. Fixed a bug in the parameter substring expansion to handle conditional
+    arithmetic expressions ( exp ? val1 : val2 ) without cutting the expression
+    off at the wrong `:'.
+
+hh. The `<>' redirection is no longer subject to the current setting of
+    `noclobber', as POSIX.2 specifies.
+
+ii. Fixed a bug in the conditional command parsing code that caused expressions
+    in parentheses to occasionally be parsed incorrectly.
+
+jj. Fixed a bug in the ((...)) arithmetic command to allow do...done or
+    {...} to follow the )) without an intervening list terminator.
+
+kk. `printf' now treats `\E' the same as `\e' when performing backslash escape
+    expansion for the `%b' format specifier.
+
+ll. When in POSIX mode, the shell no longer searches the current directory for
+    a file to be sourced with `.' or `source' if `.' is not in $PATH.
+
+mm. Interactive comments are no longer turned off when POSIX mode is disabled.
+
+nn. The UID, EUID, HOSTNAME variables are not set if they are in the shell's
+    environment when it starts up.
+
+oo. Fixed a bug in the `command' builtin so the effect of a command like
+    `command exec 4<file' is as if the `command' had been omitted.
+
+pp. ${foo[@]} and ${foo[*]} now work as in ksh93 if `foo' is not an array
+    variable.
+
+qq. ${#foo[X]}, where X is 0, @, or *, now work as in ksh93 if `foo' is not
+    an array variable.
+
+rr. The shell's idea of an absolute pathname now takes into account a
+    possible drive specification on Cygwin and other Windows systems.
+
+ss. Fixed a bug which caused incorrect parsing of some multi-character
+    constructs if they were split across input lines with backslash-newline
+    line continuation.
+
+tt. Fixed a bug that caused restricted shell mode to be set inappropriately
+    when trying to execute a shell script without a leading `#!'.
+
+uu. Shell function definitions no longer require that the body be a group
+    command ( {...} ), as POSIX.2 requires.
+
+vv. The `cd' and `pwd' builtins now process symlinks in pathnames internally
+    and should require many fewer calls to getcwd().
+
+ww. Fixed a bug that caused a pipeline's process group to be set incorrectly
+    if one of the pipeline elements contained a command substitution.
+
+xx. Fixed a bug that caused core dumps when expanding the value of HISTIGNORE.
+
+yy. The output of `set' is now quoted using $'...' so invisible characters are
+    displayed as escape sequences.
+
+zz. Fixed the help text for `unset', since PATH and IFS may both be unset.
+
+aaa. The shell no longer puts directory names into the command hash table.
+
+bbb. Fixed a bug in `read' that caused it to occasionally free memory twice if
+     it was interrupted after reading a large amount of data.
+
+ccc. Assignment statements that attempt to assign values to readonly variables
+     now cause the command to return an error status.
+
+ddd. Fixed a bug that could cause incorrect output if a $(<file) construct was
+     interrupted.
+
+eee. GROUPS and FUNCNAME now return an error status when assignment is
+     attempted, but may be unset (in which case they lose their special
+     properties).  In all respects except unsetting, they are readonly.
+
+fff. The string-to-integer conversion code now ignores trailing whitespace in
+     the string, even if strtol(3) does not.
+
+ggg. The tcsh magic-space function now does a better job of inserting the
+     space close to where the point was before the history expansion, rather
+     than just appending it.
+
+hhh. Fixed a bug which caused a file sourced from an interactive shell to
+     fill up the jobs table if it ran lots of jobs.
+
+iii. Fixed a bug in the parameter pattern substitution code to avoid infinite
+     recursion on zero-length matches.
+
+2.  Changes to Readline
+
+a.  When setting the terminal attributes on systems using `struct termio',
+    readline waits for output to drain before changing the attributes.
+
+b.  A fix was made to the history word tokenization code to avoid attempts to
+    dereference a null pointer.
+
+c.  Readline now defaults rl_terminal_name to $TERM if the calling application
+    has left it unset, and tries to initialize with the resultant value.
+
+d.  Instead of calling (*rl_getc_function)() directly to get input in certain
+    places, readline now calls rl_read_key() consistently.
+
+e.  Fixed a bug in the completion code that allowed a backslash to quote a
+    single quote inside a single-quoted string.
+
+f.  rl_prompt is no longer assigned directly from the argument to readline(),
+    but uses memory allocated by readline.  This allows constant strings to
+    be passed to readline without problems arising when the prompt processing
+    code wants to modify the string.
+
+g.  Fixed a bug that caused non-interactive history searches to return the
+    wrong line when performing multiple searches backward for the same string.
+
+h.  Many variables, function arguments, and function return values are now
+    declared `const' where appropriate, to improve behavior when linking with
+    C++ code.
+
+i.  The control character detection code now works better on systems where
+    `char' is unsigned by default.
+
+j.  The vi-mode numeric argument is now capped at 999999, just like emacs mode.
+
+k.  The Function, CPFunction, CPPFunction, and VFunction typedefs have been
+    replaced with a set of specific prototyped typedefs, though they are
+    still in the readline header files for backwards compatibility.
+
+m.  Nearly all of the (undocumented) internal global variables in the library
+    now have an _rl_ prefix -- there were a number that did not, like
+    screenheight, screenwidth, alphabetic, etc.
+
+n.  The ding() convenience function has been renamed to rl_ding(), though the
+    old function is still defined for backwards compatibility.
+
+o.  The completion convenience functions filename_completion_function,
+    username_completion_function, and completion_matches now have an rl_
+    prefix, though the old names are still defined for backwards compatibility.
+
+p.  The functions shared by readline and bash (linkage is satisfied from bash
+    when compiling with bash, and internally otherwise) now have an sh_ prefix.
+
+q.  Changed the shared library creation procedure on Linux and BSD/OS 4.x so
+    that the `soname' contains only the major version number rather than the
+    major and minor numbers.
+
+r.  Fixed a redisplay bug that occurred when the prompt spanned more than one
+    physical line and contained invisible characters.
+
+3.  New Features in Bash
+
+a.  Added a new `--init-file' invocation argument as a synonym for `--rcfile',
+    per the new GNU coding standards.
+
+b.  The /dev/tcp and /dev/udp redirections now accept service names as well as
+    port numbers.
+
+c.  `complete' and `compgen' now take a `-o value' option, which controls some
+    of the aspects of that compspec.  Valid values are:
+
+	default - perform bash default completion if programmable
+		  completion produces no matches
+	dirnames - perform directory name completion if programmable
+		   completion produces no matches
+	filenames - tell readline that the compspec produces filenames,
+		    so it can do things like append slashes to
+		    directory names and suppress trailing spaces
+
+4.  New Features in Readline
+
+a.  The blink timeout for paren matching is now settable by applications.
+
+b.  _rl_executing_macro has been renamed to rl_executing_macro, which means
+    it's now part of the public interface.
+
+c.  Readline has a new variable, rl_readline_state, which is a bitmap that
+    encapsulates the current state of the library; intended for use by
+    callbacks and hook functions.

+    matches are returned as the result.
+
+e.  Some fixes were made for systems which do not restart read(2) when a
+    signal caught by bash is received.
+
+f.  A bug was fixed which caused the umask to be set to 0 when an invalid
+    symbolic mode mask was parsed.
+
+g.  Fixed a bug that could cause a core dump if a SIGCHLD was received while

+    redirection operators.
+
+e.  A bug was fixed that, under obscure circumstances, could confuse the
+    parser when a shell function was run by the programmable completion code.
+
+f.  A bug was fixed in the ulimit builtin for systems not using getrlimit().
+
+g.  The execution code now propagates the correct exit status back to the rest

+    word have been added.
+
+h.  Negative exponents in the arithmetic evaluation of v**e now return an

+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.04-beta4,
+and the previous version, bash-2.04-beta3.
+
+1.  Changes to Bash
+
+a.  A couple of changes were made to the redirection to attempt to avoid
+    race conditions and malicious file replacement.
+
+2.  A change was made to the string evaluation code (used for command 
+    substitution, `eval', and the `.' builtin) to fix an obscure core
+    dump on alpha machines.
+
+3.  A bug that caused $LINENO to be wrong when executing arithmetic for
+    commands was fixed.
+
+4.  A couple of memory leaks in the programmable completion code were fixed.
+
+5.  A bug that could cause a core dump by freeing memory twice during a call
+    to `eval' if `set -u' had been enabled and an undefined variable was
+    referenced was fixed.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.04-beta3,

+    core dump.
+
+c.  Fixed a bug in parsing job specifications that occasionally caused
+    core dumps when an out-of-range job was referenced.
+
+d.  Fixed the `type' and `command' builtins to do better reporting of
+    commands that are not found in $PATH or the hash table.
+
+e.  Fixed a POSIX.2 compliance problem in the command builtin -- commands
+    are supposed to be reported as full pathnames.
+
+f.  The `echo' builtin now returns failure if a write error occurs.
+
+g.  Fixed a bug which caused the locale to not be reset correctly when
+    LC_ALL was unset.
+
+h.  Changed description of `getopts' in man page and reference manual to make
+    it clear that option characters may be characters other than letters.
+
+i.  If the shell exits while in a function, make sure that any trap on EXIT
+    doesn't think the function is still executing.
+
+j.  Bashbug now tries harder to find a usable editor if $EDITOR is not set,
+    rather than simply defaulting to `emacs'.
+
+k.  Changes to the scripts that guess and canonicalize the system type, from
+    the latest `automake' distribution via Debian.
+
+l.  When using named pipes for process substitution, make sure the file
+    descriptors opened for reading are set to non-blocking mode.
+
+m.  Fixed a bug that caused termination of pipelines that are killed by a

+
+n.  When not in literal-history mode, shell comment lines are not added to
+    the history list.
+
+o.  When running in POSIX.2 mode, bash no longer performs word splitting on
+    the expanded value of the word supplied as the filename argument to
+    redirection operators.
+
+p.  The prompt string decoding code now backslash-quotes only characters that
+    are special within double quotes when expanding the \w and \W escape
+    sequences.
+
+q.  Fixed a bug in the prompt decoding code that could cause a non-interactive
+    shell to seg fault if `\u' was used in PS4 and the shell was in xtrace
+    mode.
+
+r.  Fixed a bug that caused function definitions to be printed with any
+    redirections that should be attached to the entire function before the
+    closing brace.
+
+s.  Changed the tilde expansion code for Cygwin systems to avoid creating
+    pathnames beginning with `//' if $HOME == `/'.
+
+t.  Fixed a couple of autoconf tests to avoid creating files with fixed names
+    in /tmp.
+
+u.  The `trap' and `kill' builtins now know the names of the POSIX.1b real-
+    time signals on systems which support them.
+
+2.  Changes to Readline
+
+a.  Fixed a problem with the single-quote quoting function that could cause
+    buffer overflows.
+
+b.  Fixed a bug that caused incorrect `stat characters' to be printed if
+    the files being completed were in the root directory and visible-stats
+    was enabled.
+
+3.  New Features in Bash
+
+a.  There is a new `rbash.1' manual page, from the Debian release.
+
+b.  The `--enable-usg-echo-default' option to `configure' has been renamed to
+    `--enable-xpg-echo-default'.  The old option is still there for backwards
+    compatibility.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.04-beta2,
+and the previous version, bash-2.04-beta1.
+
+1.  Changes to Bash
+
+a.  Fixed a bug that could cause pipes to be closed inappropriately in

+c.  Some changes were made to reduce bash's memory usage.
+
+d.  Fixed a problem with programmable completion and filenames to be
+    completed containing quote characters.

+e.  Changed the code the removes named pipes created for the <(...) and >(...)
+    expansions to defer removal until after any current shell function has
+    finished executing.
+
+f.  Fixed a bug in `select' which caused it to not handle the `continue'
+    builtin correctly.
+
+g.  Autoconf tests added for cygwin32 and mingw32.
+
+2.  New Features in Bash
+
+a.  The `--with-bash-malloc' configure option replaces `--with-gnu-malloc'
+    (which is still there for backwards compatibility).
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.04-beta1,
+and the previous version, bash-2.04-alpha1.
+
+1.  Changes to Bash
+
+a.  Fixed a bug in the programmable completion code that occurred when
+    trying to complete command lines containing a `;' or `@'.
+
+b.  The file descriptor from which the shell is reading a script is now
+    moved to a file descriptor above the user-addressible range.
+
+c.  Changes to `printf' so that it can handle integers beginning with 0
+    or 0x as octal and hex, respectively.
+
+d.  Fixes to the programmable completion code so it handles nonsense like
+    `compgen -C xyz' gracefully.
+
+e.  The shell no longer modifies the signal handler for SIGPROF, allowing
+    profiling again on certain systems.
+
+f.  The shell checks for a new window size, if the user has requested it,
+    after a process exits due to a signal.
+
+g.  Fixed a bug with variables with null values in a program's temporary
+    environment and the bash getenv() replacement.
+
+h.  `declare' and the other builtins that take variable assignments as
+    arguments now honor `set -a' and mark modified variables for export.
+
+i.  Some changes were made for --dump-po-strings mode when writing strings
+    with embedded newlines.
+
+j.  The code that caches export strings from the initial environment now
+    duplicates the string rather than just pointing into the environment.
+
+k.  The filename completion quoting code now uses single quotes by default
+    if the filename being completed contains newlines, since \<newline>
+    has a special meaning to the parser.
+
+l.  Bash now uses typedefs bits32_t and u_bits32_t instead of int32_t and
+    u_int32_t, respectively to avoid conflicts on certain Unix versions.
+
+m.  Configuration changes were made for: Rhapsody, Mac OS, FreeBSD-3.x.
+
+n.  Fixed a problem with hostname-to-ip-address translation in the
+    /dev/(tcp|udp)/hostname/port redirection code.
+
+o.  The texinfo manual has been reorganized slightly.
+
+p.  Filename generation (globbing) range comparisons in bracket expressions
+    no longer use strcoll(3) even if it is available, since it has unwanted
+    effects in certain locales.
+
+q.  Fixed a cosmetic problem in the source that caused the shell to not
+    compile if DPAREN_ARITHMETIC was not defined but ARITH_FOR_COMMAND was.
+
+r.  Fixed a bug in the here-document code tripped when the file descriptor
+    opened to the file containing the text of the here document was the
+    same as a redirector specified by the user.
+
+s.  Fixed a bug where the INVERT_RETURN flag was not being set for `pipeline'
+    in `time ! pipeline'.
+
+t.  Fixed a bug with the `wait' builtin which manifested itself when an
+    interrupt was received while the shell was waiting for asynchronous
+    processes in a shell script.
+
+u.  Fixed the DEBUG trap code so that it has the correct value of $?.
+
+v.  Fixed a bug in the parameter pattern substitution code that could cause
+    the shell to attempt to free unallocated memory if the pattern started
+    with `/' and an expansion error occurs.
+
+w.  Fixed a bug in the positional parameter substring code that could
+    cause the shell to loop freeing freed memory.
+
+x.  Fixed a bug in the positional parameter pattern substitution code so
+    that it correctly handles null replacement strings with a pattern
+    string prefixed with `%' or `#'.
+
+y.  The shell no longer attempts to import functions from the environment if
+    started with `-n'.
+
+z.  Fixed a bug that caused `return' in a command substitution executed in
+    a shell function to return from the function in a subshell and continue
+    execution.
+
+aa. `hash -p /pathname/with/slashes name' is no longer allowed when the shell
+    is restricted.
+
+bb. The wait* job control functions now behave better if called when there
+    are no unwaited-for children.
+
+cc. Command substitution no longer unconditionally disables job control in
+    the subshell started to run the command.
+
+dd. A bug was fixed that occasionally caused traps to mess up the parser
+    state.
+
+ee. `bashbug' now honors user headers in the mail message it sends.
+
+ff. A bug was fixed that caused the `:p' history modifier to not print the
+    history expansion if the `histverify' option was set.
+
+2.  Changes to Readline
+
+a.  Fixed a bug in the redisplay code for lines with more than 256 line
+    breaks.
+
+b.  A bug was fixed which caused invisible character markers to not be
+    stripped from the prompt string if the terminal was in no-echo mode.
+
+c.  Readline no longer tries to get the variables it needs for redisplay
+    from the termcap entry if the calling application has specified its
+    own redisplay function.  Readline treats the terminal as `dumb' in
+    this case.
+
+d.  Fixes to the SIGWINCH code so that a multiple-line prompt with escape
+    sequences is redrawn correctly.
+
+3.  New Features in Bash
+
+a.  `bashbug' now accepts `--help' and `--version' options.
+
+b.  There is a new `xpg_echo' option to `shopt' that controls the behavior
+    of echo with respect to backslash-escaped characters at runtime.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.04-alpha1,
+and the previous version, bash-2.04-devel.

+
+a.  Fixed a bug that could cause core dumps when performing substring
+    expansion.
+
+b.  Shared object configuration changes for:  Solaris, OSF/1
+
+c.  The POSIX_GLOB_LIBRARY code that uses the POSIX.2 globbing facilities
+    for pathname expansion now understands GLOBIGNORE.
+
+d.  The code that implements `eval' was changed to save the value of the
+    current prompt, so an eval in a shell function called by the programmable
+    completion code will not change the prompt to $PS2.
+
+e.  Restored the undocumented NON_INTERACTIVE_LOGIN_SHELLS #define to
+    config-top.h.  If this is defined, all login shells will read the
+    startup files, not just interactive and non-interactive started with
+    the `--login' option.
+
+f.  Fixed a bug that caused the expansion code to occasionally dump core if
+    IFS contained characters > 128.
+
+g.  Fixed a problem with the grammar so that a newline is not required
+    after the `))' in the new-style arithmetic for statement; a semicolon
+    may be used as expected.
+
+h.  Variable indirection may now reference the shell's special variables.
+
+i.  The $'...' and $"..." constructs are now added to the history correctly
+    if they contain newlines and command-oriented history is enabled.

+    of a readonly shell variable (declared with the `local' builtin).
+
+2.  Changes to Readline
+
+a.  The history file code now uses O_BINARY mode when reading and writing
+    the history file on cygwin32.
+
+3.  New Features in Bash
+
+a.  A new programmable completion facility, with two new builtin commands:
+    complete and compgen.
+
+b.  configure has a new option, `--enable-progcomp', to compile in the
+    programmable completion features (enabled by default).
+
+c.  `shopt' has a new option, `progcomp', to enable and disable programmable
+    completion at runtime.
+
+d.  Unsetting HOSTFILE now clears the list of hostnames used for completion.
+
+4.  New Features in Readline
+
+a.  A new variable, rl_gnu_readline_p, always 1.  The intent is that an
+    application can verify whether or not it is linked with the `real'
+    readline library or some substitute.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.04-devel,

+    the file descriptor from which bash is reading input.
+
+j.  Some changes were made to the replacement termcap library for better

+
+k.  Some changes were made to the tilde expansion code to handle backslash
+    as a pathname separator on MS-DOS.
+
+l.  The source has been reorganized a little bit -- there is now an `include'
+    subdirectory, and lib/posixheaders has been removed.
+
+m.  Improvements were made to the `read' builtin so that it makes many
+    fewer read(2) system calls.
+
+n.  The expansion of $- will include `c' and `s' when those options are
+    supplied at shell invocation.
+
+o.  Several improvements were made to the completion code:  variable completion
+    now works better when there are unterminated expansions, command
+    completion understands quotes better, and completion now works in certain
+    unclosed $(... constructs.
+
+p.  The arithmetic expansion code was fixed to not need the value of a
+    variable being assigned a value (fixes the "ss=09; let ss=10" bug).
+

+
+r.  The html documentation will be installed into $(htmldir) if that variable
+    has a value when `make install' is run.

+    when bash is started by sshd.
+
+t.  The SSH_CLIENT environment variable is no longer auto-exported.
+
+u.  A bug that caused redirections with (...) subshells to be performed in
+    the wrong order was fixed.
+
+v.  A bug that occasionally caused inappropriate expansion of assignment
+    statements in compound array assignments was fixed.
+
+w.  The code that parses the words in a compound array assignment was
+    simplified considerably and should work better now.
+
+x.  Fixes to the non-job-control code in nojobs.c to make it POSIX.2-compliant
+    when a user attempts to retrieve the status of a terminated background
+    process.
+
+y.  Fixes to the `printf' builtin so that it doesn't try to expand all
+    backslash escape sequences in the format string before parsing it for
+    % format specifiers.
+
+2.  Changes to Readline
+
+a.  The history library tries to truncate the history file only if it is a
+    regular file.
+
+b.  A bug that caused _rl_dispatch to address negative array indices on
+    systems with signed chars was fixed.
+
+c.  rl-yank-nth-arg now leaves the history position the same as when it was
+    called.
+
+d.  Changes to the completion code to handle MS-DOS drive-letter:pathname

+
+l.  A bug was fixed in readline's signal handling that could cause infinite
+    recursion in signal handlers.
+
+m.  A bug was fixed that caused the point to be less than zero when rl_forward
+    was given a very large numeric argument.
+
+n.  The vi-mode code now gets characters via the application-settable value
+    of rl_getc_function rather than calling rl_getc directly.
+
+3.  New Features in Bash
+
+a.  The history builtin has a `-d offset' option to delete the history entry
+    at position `offset'.
+
+b.  The prompt expansion code has two new escape sequences: \j, the number of
+    active jobs; and \l, the basename of the shell's tty device name.
+
+c.  The `bind' builtin has a new `-x' option to bind key sequences to shell
+    commands.
+
+d.  There is a new shell option, no_empty_command_completion, which, when
+    enabled, disables command completion when TAB is typed on an empty line.
+
+e.  The `help' builtin has a `-s' option to just print a builtin's usage
+    synopsis.
+
+f.  There are several new arithmetic operators:  id++, id-- (variable

+h.  The `read' builtin has a number of new options:
+	-t timeout	only wait timeout seconds for input
+	-n nchars	only read nchars from input instead of a full line
+	-d delim	read until delim rather than newline
+	-s		don't echo input chars as they are read
+
+i.  The redirection code now handles several filenames specially:
+    /dev/fd/N, /dev/stdin, /dev/stdout, and /dev/stderr, whether or
+    not they are present in the file system.
+
+j.  The redirection code now recognizes pathnames of the form
+    /dev/tcp/host/port and /dev/udp/host/port, and tries to open a socket
+    of the appropriate type to the specified port on the specified host.
+
+k.  The ksh-93 ${!prefix*} expansion, which expands to the names of all
+    shell variables whose names start with prefix, has been implemented.
+
+l.  There is a new dynamic variable, FUNCNAME, which expands to the name of
+    a currently-executing function.  Assignments to FUNCNAME have no effect.
+
+m.  The GROUPS variable is no longer readonly; assignments to it are silently
+    discarded.  This means it can be unset.
+
+4.  New Features in Readline
+
+a.  Parentheses matching is now always compiled into readline, and enabled
+    or disabled when the value of the `blink-matching-paren' variable is
+    changed.
+
+b.  MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename.
+
+c.  MS-DOS systems now use ~/_history as the default history file.
+
+d.  history-search-{forward,backward} now leave the point at the end of the
+    line when the string to search for is empty, like
+    {reverse,forward}-search-history.
+
+e.  history-search-{forward,backward} now leave the last history line found
+    in the readline buffer if the second or subsequent search fails.
+
+f.  New function for use by applications:  rl_on_new_line_with_prompt, used
+    when an application displays the prompt itself before calling readline().
+
+g.  New variable for use by applications:  rl_already_prompted.  An application
+    that displays the prompt itself before calling readline() must set this to
+    a non-zero value.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.03-release,
+and the previous version, bash-2.03-beta2.
+
+1.  Changes to Bash
+
+a.  A file descriptor leak in the `fc' builtin was fixed.
+
+b.  A bug was fixed in the `read' builtin that caused occasional spurious
+    failures when using `read -e'.
+
+c.  The version code needed to use the value of the cpp variable
+    CONF_MACHTYPE rather than MACHTYPE.
+
+d.  A new test was added to exercise the command printing and copying code.
+
+e.  A bug was fixed that caused `time' to be recognized as a reserved word
+    if it was the first pattern in a `case' statement pattern list.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.03-beta2,
+and the previous version, bash-2.03-beta1.
+
+1.  Changes to Bash
+
+a.  Slight additions to support/shobj-conf, mostly for the benefit of AIX 4.2.
+
+b.  config.{guess,sub} support added for the NEC SX4.
+
+c.  Changed some of the cross-compiling sections of the configure macros in
+    aclocal.m4 so that configure won't abort.
+
+d.  Slight changes to how the HTML versions of the bash and readline manuals
+    are generated.
+
+e.  Fixed conditional command printing to avoid interpreting printf `%'-escapes
+    in arguments to [[.
+
+f.  Don't include the bash malloc on all variants of the alpha processor.
+
+g.  Changes to configure to make --enable-profiling work on Solaris 2.x.
+
+h.  Fixed a bug that manifested itself when shell functions were called
+    between calls to `getopts'.
+
+i.  Fixed pattern substitution so that a bare `#'as a pattern causes the
+    replacement string to be prefixed to the search string, and a bare
+    `%' causes the replacement string to be appended to the search string.
+
+j.  Fixed a bug in the command execution code that caused child processes
+    to occasionally have the wrong value for $!.
+
+2.  Changes to Readline
+
+a.  Added code to the history library to catch history substitutions using
+    `&' without a previous history substitution or search having been
+    performed.
+
+3.  New Features in Bash
+
+4.  New Features in Readline
+
+a.  New bindable variable: `isearch-terminators'.
+
+b.  New bindable function: `forward-backward-delete-char' (unbound by default).
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.03-beta1,
+and the previous version, bash-2.03-alpha.
+    
+1.  Changes to Bash
+
+a.  A change was made to the help text for `{...}' to make it clear that a
+    semicolon is required before the closing brace.
+
+b.  A fix was made to the `test' builtin so that syntax errors cause test
+    to return an exit status > 1.
+
+c.  Globbing is no longer performed on assignment statements that appear as
+    arguments to `assignment builtins' such as `export'.
+
+d.  System-specific configuration changes were made for:  Rhapsody,
+    AIX 4.2/gcc, BSD/OS 4.0.
+
+e.  New loadable builtins: ln, unlink.
+
+f.  Some fixes were made to the globbing code to handle extended glob patterns
+    which immediately follow a `*'.
+
+g.  A fix was made to the command printing code to ensure that redirections
+    following compound commands have a space separating them from the rest
+    of the command.
+
+h.  The pathname canonicalization code was changed to produce fewer leading
+    `//' sequences, since those are interpreted as network file system
+    pathnames on some systems.
+
+i.  A fix was made so that loops containing `eval' commands in commands passed
+    to `bash -c' would not exit prematurely.
+
+j.  Some changes were made to the job reaping code when the shell is not
+    interactive, so the shell will retain exit statuses longer for examination
+    by `wait'.
+
+k.  A fix was made so that `jobs | command' works again.
+
+l.  The erroneous compound array assignment var=((...)) is now a syntax error.
+
+m.  A change was made to the dynamic loading code in `enable' to support
+    Tenon's MachTen.
+
+n.  A fix was made to the globbing code so that extended globbing patterns
+    will correctly match `.' in a bracket expression.
+
+2.  Changes to Readline
+
+a.  A fix was made to the completion code in which a typo caused the wrong
+    value to be passed to the function that computed the longest common
+    prefix of the list of matches.
+
+b.  The completion code now checks the value of rl_filename_completion_desired,
+    which is set by application-supplied completion functions to indicate
+    that filename completion is being performed, to decide whether or not to
+    call an application-supplied `ignore completions' function.
+
+3.  New Features in Bash
+
+a.  A change was made to the startup file code so that any shell begun with
+    the `--login' option, even non-interactive shells, will source the login
+    shell startup files.
+
+4.  New Features in Readline
+
+a.  A new variable, rl_erase_empty_line, which, if set by an application using
+    readline, will cause readline to erase, prompt and all, lines on which the
+    only thing typed was a newline.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.03-alpha,
+and the previous version, bash-2.02.1-release.
+
+1.  Changes to Bash
+
+a.  System-specific configuration changes were made for: Irix 6.x, Unixware 7.
+
+b.  The texi2dvi and texi2html scripts were updated to the latest versions
+    from the net.
+
+c.  The configure tests that determine which native type is 32 bits were
+    changed to not require a compiled program.
+
+d.  Fixed a bug in shell_execve that could cause memory to be freed twice
+    after a failed exec.
+
+e.  The `printf' test uses `diff -a' if it's available to prevent confusion
+    due to the non-ascii output.
+
+f.  Shared object configuration is now performed by a shell script,
+    support/shobj-conf, which generates values to be substituted into
+    makefiles by configure.
+
+g.  Some changes were made to `ulimit' to avoid the use of RLIM_INVALID as a
+    return value.
+
+h.  Changes were made to `ulimit' to work around HPUX 9.x's peculiar
+    handling of RLIMIT_FILESIZE.
+
+i.  Some new loadable builtins were added: id, printenv, sync, whoami, push,
+    mkdir.  `pushd', `popd', and `dirs' can now be built as regular or
+    loadable builtins from the same source file.
+
+j.  Changes were made to `printf' to handle NUL bytes in the expanded format
+    string.
+
+k.  The various `make clean' Makefile targets now descend into lib/sh.
+
+l.  The `type' builtin was changed to use the internal `getopt' so that things
+    like `type -ap' work as expected.
+
+m.  There is a new configuration option, --with-installed-readline, to link
+    bash with a locally-installed version of readline.  Only readline version
+    4.0 and later releases can support this.  Shared and static libraries
+    are supported.  The installed include files are used.
+
+n.  There is a new autoconf macro used to find which basic type is 64 bits.
+
+o.  Dynamic linking and loadable builtins should now work on SCO 3.2v5*,
+    AIX 4.2 with gcc, Unixware 7, and many other systems using gcc, where
+    the `-shared' options works correctly.
+
+p.  A bug was fixed in the bash filename completion code that caused memory to
+    be freed twice if a directory name containing an unset variable was
+    completed and the -u option was set.
+
+q.  The prompt expansion code now quotes the `$' in the `\$' expansion so it
+    is not processed by subsequent parameter expansion.
+
+r.  Fixed a parsing bug that caused a single or double quote after a `$$' to
+    trigger ANSI C expansion or locale translation.
+
+s.  Fixed a bug in the globbing code that caused quoted filenames containing
+    no globbing characters to sometimes be incorrectly expanded.
+
+t.  Changes to the default prompt strings if prompt string decoding is not
+    compiled into the shell.
+
+u.  Added `do', `then', `else', `{', and `(' to the list of keywords that may
+    precede the `time' reserved word.
+
+v.  The shell may now be cross-built for BeOS as well as cygwin32.
+
+w.  The conditional command execution code now treats `=' the same as `=='
+    for deciding when to perform pattern matching.
+
+x.  The `-e' option no longer causes the shell to exit if a command exits
+    with a non-zero status while running the startup files.
+
+y.  The `printf' builtin no longer dumps core if a modifier is supplied in
+    the format string without a conversion character (e.g. `%h').
+
+z.  Array assignments of the form a=(...) no longer show up in the history
+    list.
+
+aa. The parser was fixed to obey the POSIX.2 rules for finding the closing
+    `}' in a ${...} expression.
+
+bb. The history file is now opened with mode 0600 rather than 0666, so bash
+    no longer relies on the user's umask being set appropriately.
+
+cc. Setting LANG no longer causes LC_ALL to be assigned a value; bash now
+    relies on proper behavior from the C library.
+
+dd. Minor changes were made to allow quoted variable expansions using
+    ${...} to be completed correctly if there is no closing `"'.
+
+ee. Changes were made to builtins/Makefile.in so that configuring the shell
+    with `--enable-profiling' works right and builtins/mkbuiltins is
+    generated.
+
+2.  Changes to Readline
+
+a.  The version number is now 4.0.
+
+b.  There is no longer any #ifdef SHELL code in the source files.
+
+c.  Some changes were made to the key binding code to fix memory leaks and
+    better support Win32 systems.
+
+d.  Fixed a silly typo in the paren matching code -- it's microseconds, not
+    milliseconds.
+
+e.  The readline library should be compilable by C++ compilers.
+
+f.  The readline.h public header file now includes function prototypes for
+    all readline functions, and some changes were made to fix errors in the
+    source files uncovered by the use of prototypes.
+
+g.  The maximum numeric argument is now clamped at 1000000.
+
+h.  Fixes to rl_yank_last_arg to make it behave better.
+
+i.  Fixed a bug in the display code that caused core dumps if the prompt
+    string length exceeded 1024 characters.
+
+j.  The menu completion code was fixed to properly insert a single completion
+    if there is only one match.
+
+k.  A bug was fixed that caused the display code to improperly display tabs
+    after newlines.
+
+3.  New Features in Bash
+
+a.  New `shopt' option, `restricted_shell', indicating whether or not the
+    shell was started in restricted mode, for use in startup files.
+
+b.  Filename generation is now performed on the words between ( and ) in
+    array assignments (which it probably should have done all along).
+
+c.  OLDPWD is now auto-exported, as POSIX.2 seems to require.
+
+d.  ENV and BASH_ENV are read-only variables in a restricted shell.
+
+4.  New Features in Readline
+
+a.  Many changes to the signal handling:
+	o Readline now catches SIGQUIT and cleans up the tty before returning;
+	o A new variable, rl_catch_signals, is available to application writers 
+	  to indicate to readline whether or not it should install its own
+	  signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP,
+	  SIGTTIN, and SIGTTOU;
+	o A new variable, rl_catch_sigwinch, is available to application
+	  writers to indicate to readline whether or not it should install its
+	  own signal handler for SIGWINCH, which will chain to the calling
+	  applications's SIGWINCH handler, if one is installed;
+	o There is a new function, rl_free_line_state, for application signal
+	  handlers to call to free up the state associated with the current
+	  line after receiving a signal;
+	o There is a new function, rl_cleanup_after_signal, to clean up the
+	  display and terminal state after receiving a signal;
+	o There is a new function, rl_reset_after_signal, to reinitialize the
+	  terminal and display state after an application signal handler
+	  returns and readline continues
+
+b.  There is a new function, rl_resize_terminal, to reset readline's idea of
+    the screen size after a SIGWINCH.
+
+c.  New public functions: rl_save_prompt and rl_restore_prompt.  These were
+    previously private functions with a `_' prefix.
+
+d.  New function hook: rl_pre_input_hook, called just before readline starts
+    reading input, after initialization.
+
+e.  New function hook: rl_display_matches_hook, called when readline would
+    display the list of completion matches.  The new function
+    rl_display_match_list is what readline uses internally, and is available
+    for use by application functions called via this hook.
+
+f.  New bindable function, delete-char-or-list, like tcsh.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.02.1-release,
+and the previous version, bash-2.02-release.
+
+1.  Changes to Bash
+
+a.  A bug that caused the bash readline support to not compile unless aliases
+    and csh-style history were configured into the shell was fixed.
+
+b.  Fixed a bug that could cause a core dump when here documents contained
+    more than 1000 characters.
+
+c.  Fixed a bug that caused a CDPATH entry of "" to not be treated the same
+    as the current directory when in POSIX mode.
+
+d.  Fixed an alignment problem with the memory returned by the bash malloc,
+    so returned memory is now 64-bit aligned.
+
+e.  Fixed a bug that caused command substitutions executed within pipelines
+    to put the terminal in the wrong process group.
+
+f.  Fixes to support/config.sub for: alphas, SCO Open Server and Open Desktop,
+    Unixware 2, and Unixware 7.
+
+g.  Fixes to the pattern matching code to make it work correctly for eight-bit
+    characters.
+
+h.  Fixed a problem that occasionally caused the shell to display the wrong
+    value for the new working directory when changing to a directory found
+    in $CDPATH when in physical mode.
+
+i.  Fixed a bug that caused core dumps when using conditional commands in
+    shell functions.
+
+j.  Fixed a bug that caused the printf builtin to loop forever if the format
+    string did not consume any of the arguments.
+
+k.  Fixed a bug in the parameter expansion code that caused "$@" to be
+    incorrectly split if $IFS did not contain a space character.
+
+l.  Fixed a bug that could cause a core dump when completing hostnames if
+    the number of matching hostnames was an exact multiple of 16.
+
+m.  Fixed a bug that caused the shell to fork too early when a command
+    such as `%2 &' was given.
+
+2.  Changes to Readline
+
+a.  Fixed a problem with redisplay that showed up when the prompt string was
+    longer than the screen width and the prompt contained invisible characters.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.02-release,
+and the previous version, bash-2.02-beta2.
+
+1.  Changes to Bash
+
+a.  A bug was fixed that caused the terminal process group to be set
+    incorrectly when performing command substitution of builtins in a
+    pipeline.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.02-beta2,

+
+1.  Changes to Bash
+
+a.  Attempting to `wait' for stopped jobs now generates a warning message.
+
+b.  Pipelines which exit due to SIGPIPE in non-interactive shells are now
+    not reported if the shell is compiled -DDONT_REPORT_SIGPIPE.
+
+c.  Some changes were made to builtins/psize.sh and support/bashbug.sh to
+    attempt to avoid some /tmp file races and surreptitious file
+    substitutions.
+
+d.  Fixed a bug that caused the shell not to compile if configured with
+    dparen arithmetic but without aliases.
+
+e.  Fixed a bug that caused the input stream to be switched when assigning
+    empty arrays with `bash -c'.
+
+f.  A bug was fixed in the readline expansion glue code that caused bash to
+    dump core when expanding lines with an unclosed single quote.
+
+g.  A fix was made to the `cd' builtin so that using a non-empty directory
+    from $CDPATH results in an absolute pathname of the new current working
+    directory to be displayed after the current directory is changed.
+
+h.  Fixed a bug in the variable assignment code that caused the shell to
+    dump core when referencing an unset variable with `set -u' enabled in
+    an assignment statement preceding a command.
+
+i.  Fixed a bug in the exit trap code that caused reserved words to not be
+    recognized under certain circumstances.

+    arguments.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.02-beta1,
+and the previous version, bash-2.02-alpha1.
+
+1.  Changes to Bash
+
+a.  A few compilation bugs were fixed in the new extended globbing code.
+
+b.  Executing arithmetic commands now sets the command name to `((' so
+    error messages look right.
+
+c.  Fixed some build problems with various configuration options.
+
+d.  The `printf' builtin now aborts immediately if an illegal format
+    character is encountered.
+
+e.  The code that creates here-documents now behaves better if the file it's
+    trying to create already exists for some reason.
+
+f.  Fixed a problem with the extended globbing code that made patterns like
+    `x+*' expand incorrectly.
+
+g.  The prompt string expansion code no longer quotes tildes with backslashes.
+
+h.  The bash getcwd() implementation in lib/sh/getcwd.c now behaves better in
+    the presence of lstat(2) failures.
+
+i.  Fixed a bug with strsub() that caused core dumps when executing `fc -s'.
+
+j.  The mail checking code now ensures that it has a valid default mailpath.
+
+k.  A bug was fixed that caused local variables to be unset inappropriately
+    when sourcing a script from within another sourced script.
+
+l.  A bug was fixed in the history saving code so that functions are saved
+    in the history list correctly if `cmdhist' is enabled, but `lithist'
+    is not.
+
+m.  A bug was fixed that caused printf overflows when displaying error
+    messages.
+
+n.  It should be easier to build the loadble builtins in examples/loadables,
+    though some manual editing of the generated Makefile is still required.
+
+o.  The user's primary group is now always ${GROUPS[0]}.
+
+p.  Some updates were made to support/config.guess from the GNU master copy.
+
+q.  Some changes were made to the autoconf support for Solaris 2.6 large
+    files.
+
+r.  The `command' builtins now does the right thing when confstr(3) cannot
+    find a value for _CS_PATH.
+
+s.  Extended globbing expressions like `*.!(c)' are not history expanded if
+    `extglob' is enabled.
+
+t.  Using the `-P' option to `cd' will force the value that is assigned to
+    PWD to not contain any symbolic links.
+
+2.  Changes to Readline
+
+a.  The code that prints completion listings now behaves better if one or
+    more of the filenames contains non-printable characters.
+
+b.  The time delay when showing matching parentheses is now 0.5 seconds.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.02-alpha1,
+and the previous version, bash-2.01.1-release.
+
+1.  Changes to Bash
+
+a.  OS-specific configuration changes for:  BSD/OS 3.x, Minix 2.x,
+    Solaris 2.6, SINIX SVR4.
+
+b.  Changes were made to the generated `info' files so that `install-info'
+    works correctly.
+
+c.  PWD is now auto-exported.
+
+d.  A fix was made to the pipeline code to make sure that the shell forks
+    to execute simple commands consisting solely of assignment statements.
+
+e.  Changes to the test suite for systems with 14-character filenames.
+
+f.  The default sizes of some internal hash tables have been made smaller
+    to reduce the shell's memory footprint.
+
+g.  The `((...))' arithmetic command is now executed directly instead of
+    being translated into `let "..."'.
+
+h.  Fixes were made to the expansion code so that "$*", "$@", "${array[@]}",
+    and "${array[@]}" expand correctly when IFS does not contain a space
+    character, is unset, or is set to NULL.
+
+i.  The indirect expansion code (${!var}) was changed so that the only
+    valid values of `var' are variable names, positional parameters, `#',
+    `@', and `*'.
+
+j.  An arithmetic expression error in a $((...)) expansion now causes a
+    non-interactive shell running in posix mode to exit.
+
+k.  Compound array assignment now splits the words within the parentheses
+    on shell metacharacters like the parser would before expansing them
+    and performing the assignment.  This is for compatibility with ksh-93.
+
+l.  The internal shell backslash-quoting code (used in the output of `set'
+    and completion) now quotes tildes if they appear at the start of the
+    string or after a `=' or `:'.
+
+m.  A couple of bugs with `shopt -o' were fixed.
+
+n.  `bash +o' now displays the same output as `set +o' before starting an
+    interactive shell.
+
+o.  A bug that caused command substitution and the `eval' builtin to
+    occasionally free memory twice when an error was encountered was fixed.
+
+p.  The filename globbing code no longer requires read permission for a
+    directory when the filename to be matched does not contain any globbing
+    characters, as POSIX.2 specifies.
+
+q.  A bug was fixed so that the job containing the last asynchronous
+    process is not removed from the job table until a `wait' is executed
+    for that process or another asynchronous process is started.  This
+    satisfies a POSIX.2 requirement.
+
+r.  A `select' bug was fixed so that a non-numeric user response is treated
+    the same as a numeric response that is out of range.
+
+s.  The shell no longer parses the value of SHELLOPTS from the environment
+    if it is restricted, running setuid, or running in `privileged mode'.
+
+t.  Fixes were made to enable large file support on systems such as
+    Solaris 2.6, where the size of a file may be larger than can be held
+    in an `int'.
+
+u.  The filename hashing code was fixed to not add `./' to the beginning of
+    filenames which already begin with `./'.
+
+v.  The configure script was changed so that the GNU termcap library is not
+    compiled in if `prefer-curses' has been specified.
+
+w.  HISTCONTROL and HISTIGNORE are no longer applied to the second and
+    subsequent lines of a multi-line command.
+
+x.  A fix was made to `disown' so that it does a better job of catching
+    out-of-range jobs.
+
+y.  Non-interactive shells no longer report the status of processes terminated
+    due to SIGINT, even if the standard output is a terminal.
+
+z.  A bug that caused the output of `jobs' to have extra carriage returns
+    was fixed.
+
+aa. A bug that caused PIPESTATUS to not be set when builtins or shell
+    functions were executed in the foreground was fixed.
+
+bb. Bash now attempts to detect when it is being run by sshd, and treats
+    that case identically to being run by rshd.
+
+cc. A bug that caused `set -a' to export SHELLOPTS when one of the shell
+    options was changed was fixed.
+
+dd. The `kill' builtin now disallows empty or missing process id arguments
+    instead of treating them as identical to `0', which means the current
+    process.
+
+ee. `var=value declare -x var' now behaves identically to
+    `var=value export var'.  Similarly for `var=value declare -r var' and
+    `var=value readonly var'.
+
+ff. A few memory leaks were fixed.
+
+gg. `alias' and `unalias' now print error messages when passed an argument
+    that is not an alias for printing or deletion, even when the shell is
+    not interactive, as POSIX.2 specifies.
+
+hh. `alias' and `alias -p' now return a status of 0 when no aliases are
+    defined, as POSIX.2 specifies.
+
+ii. `cd -' now prints the pathname of the new working directory if the shell
+    is interactive.
+
+jj. A fix was made so that the code that binds $PWD now copes with getcwd()
+    returning NULL.
+
+kk. `unset' now checks whether or not a function name it's trying to unset
+    is a valid shell identifier only when the shell is running in posix mode.
+
+ll. A change was made to the code that generates filenames for here documents
+    to make them less prone to name collisions.
+
+mm. The parser was changed so that `time' is recognized as a reserved word
+    only at the beginning of a pipeline.
+
+nn. The pathname canonicalization code was changed so that `//' is converted
+    into `/', but all other pathnames beginning with `//' are left alone, as
+    POSIX.2 specifies.
+
+oo. The `logout' builtin will no longer exit a non-interactive non-login
+    shell.
+
+2.  Changes to Readline
+
+a.  Fixed a problem in the readline test program rltest.c that caused a core
+    dump.
+
+b.  The code that handles parser directives in inputrc files now displays
+    more error messages.
+
+c.  The history expansion code was fixed so that the appearance of the
+    history comment character at the beginning of a word inhibits history
+    expansion for that word and the rest of the input line.
+
+3.  New Features in Bash
+
+a.  A new version of malloc, based on the older GNU malloc, that has many
+    changes, is more page-based, is more conservative with memory usage,
+    and does not `orphan' large blocks when they are freed.
+
+b.  A new version of gmalloc, based on the old GLIBC malloc, with many
+    changes and range checking included by default.
+
+c.  A new implementation of fnmatch(3) that includes full POSIX.2 Basic
+    Regular Expression matching, including character classes, collating
+    symbols, equivalence classes, and support for case-insensitive pattern
+    matching.
+
+d.  ksh-88 egrep-style extended pattern matching ([@+*?!](patlist)) has been
+    implemented, controlled by a new `shopt' option, `extglob'.
+
+e.  There is a new ksh-like `[[' compound command, which implements
+    extended `test' functionality.
+
+f.  There is a new `printf' builtin, implemented according to the POSIX.2
+    specification.
+
+g.  There is a new feature for command substitution: $(< filename) now expands
+    to the contents of `filename', with any trailing newlines removed
+    (equivalent to $(cat filename)).
+
+h.  There are new tilde prefixes which expand to directories from the
+    directory stack.
+
+i.  There is a new `**' arithmetic operator to do exponentiation.
+
+j.  There are new configuration options to control how bash is linked:
+    `--enable-profiling', to allow bash to be profiled with gprof, and
+    `--enable-static-link', to allow bash to be linked statically.
+
+k.  There is a new configuration option, `--enable-cond-command', which
+    controls whether or not the `[[' command is included.  It is on by
+    default.
+
+l.  There is a new configuration option, `--enable-extended-glob', which
+    controls whether or not the ksh extended globbing feature is included.
+    It is enabled by default.
+
+m.  There is a new configuration #define in config.h.top that, when enabled,
+    will cause all login shells to source /etc/profile and one of the user-
+    specific login shell startup files, whether or not the shell is
+    interactive.
+
+n.  There is a new invocation option, `--dump-po-strings', to dump
+    a shell script's translatable strings ($"...") in GNU `po' format.
+
+o.  There is a new `shopt' option, `nocaseglob', to enable case-insensitive
+    pattern matching when globbing filenames and using the `case' construct.
+
+p.  There is a new `shopt' option, `huponexit', which, when enabled, causes
+    the shell to send SIGHUP to all jobs when an interactive login shell
+    exits.
+
+q.  `bind' has a new `-u' option, which takes a readline function name as an
+    argument and unbinds all key sequences bound to that function in a
+    specified keymap.
+
+r.  `disown' now has `-a' and `-r' options, to limit operation to all jobs
+    and running jobs, respectively.
+
+s.  The `shopt' `-p' option now causes output to be displayed in a reusable
+    format.
+
+t.  `test' has a new `-N' option, which returns true if the filename argument
+    has been modified since it was last accessed.
+
+u.  `umask' now has a `-p' option to print output in a reusable format.
+
+v.  A new escape sequence, `\xNNN', has been added to the `echo -e' and $'...'
+    translation code.  It expands to the character whose ascii code is NNN
+    in hexadecimal.
+
+w.  The prompt string expansion code has a new `\r' escape sequence.
+
+x.  The shell may now be cross-compiled for the CYGWIN32 environment on
+    a Unix machine.
+
+4.  New Features in Readline
+
+a.  There is now an option for `iterative' yank-last-arg handline, so a user
+    can keep entering `M-.', yanking the last argument of successive history
+    lines.
+
+b.  New variable, `print-completions-horizontally', which causes completion
+    matches to be displayed across the screen (like `ls -x') rather than up
+    and down the screen (like `ls').
+
+c.  New variable, `completion-ignore-case', which causes filename completion
+    and matching to be performed case-insensitively.
+
+d.  There is a new bindable command, `magic-space', which causes history
+    expansion to be performed on the current readline buffer and a space to
+    be inserted into the result.
+
+e.  There is a new bindable command, `menu-complete', which enables tcsh-like
+    menu completion (successive executions of menu-complete insert a single
+    completion match, cycling through the list of possible completions).
+
+f.  There is a new bindable command, `paste-from-clipboard', for use on Win32
+    systems, to insert the text from the Win32 clipboard into the editing
+    buffer.
+
+g.  The key sequence translation code now understands printf-style backslash
+    escape sequences, including \NNN octal escapes.  These escape sequences
+    may be used in key sequence definitions or macro values.
+
+h.  An `$include' inputrc file parser directive has been added.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.01.1-release,
+and the previous version, bash-2.01-release.
+
+1.  Changes to Bash
+
+a.  The select command was fixed to check the validity of the user's
+    input more strenuously.
+
+b.  A bug was fixed that prevented `time' from timing commands correctly
+    when supplied as an argument to `bash -c'.
+
+c.  A fix was made to the mail checking code to keep from adding the same
+    mail file to the list of files to check multiple times when parsing
+    $MAILPATH.
+
+d.  Fixed an off-by-one error in the tilde expansion library.
+
+e.  When using the compound array assignment syntax, the old value of
+    the array is cleared before assigning the new value.
+
+f.  Fixed a bug that could cause a core dump when a trap handler was reset
+    to the default in the trap command associated with that signal.
+
+g.  Fixed a bug in the locale code that occurred when assigning a value
+    to LC_ALL.
+
+h.  A change was made to the parser so that words of the form xxx=(...)
+    are not considered compound assignment statements unless there are
+    characters before the `='.
+
+i.  A fix was made to the command tracing code to correctly quote each
+    word of output.
+
+j.  Some changes were made to the bash-specific autoconf tests to make them
+    more portable.
+
+k.  Completion of words with globbing characters now correctly quotes the
+    result.
+
+l.  The directory /var/spool/mail is now preferred to /usr/spool/mail when
+    configure is deciding on the default mail directory.
+
+m.  The brace completion code was fixed to not quote the `{' and `}'.
+
+n.  Some fixes were made to make $RANDOM more random in subshells.
+
+o.  System-specific changes were made to configure for: SVR4.2
+
+p.  Changes were made so that completion of words containing globbing chars
+    substitutes the result only if a single filename was matched.
+
+q.  The window size is now recomputed after a job is stopped with SIGTSTP if
+    the user has set `checkwinsize' with `shopt'.
+
+r.  When doing substring expansion, out-of-range substring specifiers now
+    cause nothing to be substituted rather than an expansion error.
+
+s.  A fix was made so that you can no longer trap `SIGEXIT' or `SIGDEBUG' --
+    only `EXIT' and `DEBUG' are accepted.
+
+t.  The display of trapped signals now uses the signal number if signals
+    for which bash does not know the name are trapped.
+
+u.  A fix was made so that `bash -r' does not turn on restricted mode until
+    after the startup files are executed.
+
+v.  A bug was fixed that occasionally caused a core dump when a variable
+    found in the temporary environment of export/declare/readonly had a
+    null value.
+
+w.  A bug that occasionally caused unallocated memory to be passed to free()
+    when doing arithmetic substitution was fixed.
+
+x.  A bug that caused a buffer overrun when expanding a prompt string
+    containing `\w' and ${#PWD} exceeded PATH_MAX was fixed.
+
+y.  A problem with the completion code that occasionally caused it to
+    refer to a character before the beginning of the readline line buffer
+    was fixed.
+
+z.  A bug was fixed so that the `read' builtin restarts reads when
+    interrupted by signals other than SIGINT.
+
+aa. Fixed a bug that caused a command to be freed twice when there was
+    an evaluation error in the `eval' command.
+
+2.  Changes to Readline
+
+a.  Added a missing `extern' to a declaration in readline.h that kept
+    readline from compiling cleanly on some systems.
+
+b.  The history file is now opened with mode 0600 when it is written for
+    better security.
+
+c.  Changes were made to the SIGWINCH handling code so that prompt redisplay
+    is done better.
+
+d.  ^G now interrupts incremental searches correctly.
+
+e.  A bug that caused a core dump when the set of characters to be quoted
+    when completing words was empty was fixed.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.01-release,
+and the previous version, bash-2.01-beta2.
+
+1.  Changes to Bash
+
+a.  The `distclean' target should remove the `printenv' executable if it
+    has been created.
+
+b.  The test suite was changed slightly to ensure that the error messages
+    are printed in English.
+
+c.  A bug that caused the shell to dump core when a filename containing a
+    `/' was passed to `hash' was fixed.
+
+d.  Pathname canonicalization now leaves a leading `//' intact, as POSIX.1
+    requires.
+
+e.  A memory leak when completing commands was fixed.
+
+f.  A memory leak that occurred when checking the hash table for commands
+    with relative paths was fixed.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.01-beta2,
+and the previous version, bash-2.01-beta1.
+
+1.  Changes to Bash
+
+a.  The `ulimit' builtin translates RLIM_INFINITY to the hard limit only if
+    the current (soft) limit is less than or equal to the hard limit.
+
+b.  Fixed a bug that caused the bash emulation of strcasecmp to produce
+    incorrect results.
+
+c.  A bug that caused memory to be freed twice when a trap handler resets
+    the trap more than once was fixed.
+
+d.  A bug that caused machines where sizeof (pointer) > sizeof (int) to
+    fail (and possibly dump core) when trying to unwind-protect a null
+    pointer was fixed.
+
+e.  The startup files should not be run with job control enabled.  This fix
+    allows SIGINT to once again interrupt startup file execution.
+
+f.  Bash should not change the SIGPROF handler if it is set to something
+    other than SIG_DFL.
+
+g.  The completion code that provides bash-specific completions for readline
+    now quotes characters that the readline code would treat as word break
+    characters if they appear in a file name.
+
+h.  The completion code now correctly quotes filenames containing a `!',
+    even if the user attempted to use double quotes when attempting
+    completion.
+
+i.  A bug that caused the shell to dump core when `disown' was called without
+    arguments and there was no current job was fixed.
+
+j.  A construct like $((foo);bar) is now processed as a command substitution
+    rather than as a bad arithmetic substitution.
+
+k.  A couple of bugs that caused `fc' to not obey the `cmdhist' and `lithist'
+    shell options when editing and re-executing a series of commands were
+    fixed.
+
+l.  A fix was made to the grammar -- the list of commands between `do' and
+    `done' in the body of a `for' command should be treated the same as a
+    while loop.
+
+2.  Changes to Readline
+
+a.  A couple of bugs that caused the history search functions to attempt to
+    free a NULL pointer were fixed.
+
+b.  If the C library provides setlocale(3), readline does not need to look
+    at various environment variables to decide whether or not to go into
+    eight-bit mode automatically -- just check whether the current locale
+    is not `C' or `POSIX'.
+
+c.  If the filename completion function finds that a directory was not closed
+    by a previous (interrupted) completion, it closes the directory with
+    closedir().
+
+3.  New Features in Bash
+
+a.  New bindable readline commands:  history-and-alias-expand-line and
+    alias-expand-line.  The code was always in there, there was just no
+    way to execute it.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.01-beta1,
+and the previous version, bash-2.01-alpha1.
+
+1.  Changes to Bash
+
+a.  Fixed a problem that could cause file descriptors used for process
+    substitution to conflict with those used explicitly in redirections.
+
+b.  Made it easier to regenerate configure if the user changes configure.in.
+
+c.  ${GROUPS[0]} should always be the primary group, even on systems without
+    multiple groups.
+
+d.  Spelling correction is no longer enabled by default.
+
+e.  Fixes to quoting problems in `bashbug'.
+
+f.  OS-specific configuration changes were made for: Irix 6.
+
+g.  OS-specific code changes were made for: QNX.
+
+h.  A more meaningful message is now printed when the file in /tmp for a
+    here document cannot be created.
+
+i.  Many changes to the shell's variable initialization code to speed
+    non-interactive startup.
+
+j.  Changes to the non-job-control code so that it does not try to open
+    /dev/tty.
+
+k.  The output of `set' and `export' is once again sorted, as POSIX wants.
+
+l.  Fixed a problem caused by a recursive call reparsing the value of
+    $SHELLOPTS.
+
+m.  The tilde code no longer calls getenv() when it's compiled as part of
+    the shell, which should eliminate problems on systems that cannot
+    redefine getenv(), like the NeXT OS.
+
+n.  Fixed a problem that caused `bash -o' or `bash +o' to not list all
+    the shell options.
+
+o.  Fixed `ulimit' to convert RLIM_INFINITY to the appropriate hard limit
+    only if the hard limit is greater than the current (soft) limit.
+
+p.  Fixed a problem that arose when building bash in a different directory
+    than the source and y.tab.[ch] were remade with something other than
+    bison.  This came up most often on NetBSD.
+
+q.  Fixed a problem with completion -- it thought that `pwd`/[TAB] indicated
+    an unfinished command completion (`/), which generated errors.
+
+r.  The bash special tilde expansions (~-, ~+) are now attempted before
+    calling the standard tilde expansion code, which should eliminate the
+    problems people have been seeing with this on Solaris 2.5.1.
+
+s.  Added support for <stdarg.h> to places where it was missing.
+
+t.  Changed the code that reads the output of a command substitution to not
+    go through stdio.  This reduces the memory requirements and is faster.
+
+u.  A number of changes to speed up export environment creation were made.
+
+v.  A number of memory leaks were fixed as the result of running the test
+    scripts through Purify.
+
+w.  Fixed a bug that caused subshells forked to interpret executable
+    scripts without a leading `#!' to not reinitialize the values of
+    the shell options.
+
+2.  Changes to Readline
+
+a.  History library has less `#ifdef SHELL' code -- abstracted stuff out
+    into application-specific function hooks.
+
+b.  Readline no longer calls getenv() if it's compiled as part of the shell,
+    which should eliminate problems on systems that cannot redefine getenv(),
+    like the NeXT OS.
+
+c.  Fixed translation of ESC when `untranslating' macro values.
+
+d.  The region kill operation now fixes the mark if it ends up beyond the
+    boundaries of the line after the region is deleted.
+
+3.  New Features in Bash
+
+a.  New argument for `configure':  `--with-curses'.  This can be used to
+    override the selection of the termcap library on systems where it is
+    deficient.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.01-alpha1,
+and the previous version, bash-2.0-release.
+
+1.  Changes to Bash
+
+a.  System-specific configuration changes for: FreeBSD, SunOS4, Irix,
+    MachTen, QNX 4.2, Harris Night Hawk, SunOS5.
+
+b.  System-specific code changes were made for: Linux, 4.4 BSD, QNX 4.2,
+    HP-UX, AIX 4.2.
+
+c.  A bug that caused the exec builtin to fail because the full pathname of
+    the command could not be found was fixed.
+
+d.  The code that performs output redirections is now more resistant to
+    race conditions and possible security exploits.
+
+e.  A bug that caused the shell to dump core when performing pattern
+    substitutions on variable values was fixed.
+
+f.  More hosts are now recognized by the auto-configuration mechanism
+    (OpenBSD, QNX, others).
+
+g.  Assignments to read-only variables that attempt to convert them to
+    arrays are now errors.
+
+h.  A bug that caused shell scripts using array assignments in POSIX mode
+    to exit after the assignment was performed was fixed.
+
+i.  The substring expansion code is now more careful about running off the
+    ends of the expanded variable value.
+
+j.  A bug that caused completion to fail if a backquoted command substitution
+    appeared anywhere on the line was fixed.
+
+k.  The `source' builtin no longer turns off history if it has been enabled
+    in a non-interactive shell.
+
+l.  A bug that caused the shell to crash when `disown' was given a pid
+    instead of a job number was fixed.
+
+m.  The `cd' spelling correction code will not try to change to `.' if no
+    directory entries match a single-character argument.
+
+n.  A bad variable name supplied to `declare', `export', or `readonly' no
+    longer causes a non-interactive shell in POSIX mode to exit.
+
+o.  Some fixes were made to the test suite to handle peculiarities of
+    various Unix versions.
+
+p.  The bash completion code now quotes characters that readline would
+    treat as word breaks for completion but are not shell metacharacters.
+
+q.  Bad options supplied at invocation now cause a usage message to be
+    displayed.
+
+r.  Fixes were made to the code that handles DEBUG traps so that the trap
+    string is not freed inappropriately.
+
+s.  Some changes were made to the bash debugger in examples/bashdb -- it
+    should be closer to working now.
+
+t.  A problem that caused the default filename used for mail checking to be
+    wrong was fixed.
+
+u.  A fix was made to the `echo' builtin so that NUL characters printed with
+    `echo -e' do not cause the output to be truncated.
+
+v.  A fix was made to the job control code so that the shell behaves better
+    when monitor mode is enabled in a non-interactive shell.
+
+w.  Bash no longer catches all of the terminating signals in a non-
+    interactive shell until a trap is set on EXIT, which should result in
+    quicker startup.
+
+x.  A fix was made to the command timing code so that `time' can be used in
+    a loop.
+
+y.  A fix was made to the parser so that `((cmd); cmd2)' is now parsed as
+    a nested subshell rather than strictly as an (erroneous) arithmetic
+    command.
+
+z.  A fix was made to the globbing code so that it correctly matches quoted
+    filenames beginning with a `.'.
+
+aa. A bug in `fc' that caused some multi-line commands to not be stored as
+    one command in the history when they were re-executed after editing
+    (with `fc -e') was fixed.
+
+bb. The `ulimit' builtin now attempts to catch some classes of integer
+    overflows.
+
+cc. The command-oriented-history code no longer attempts to add `;'
+    inappropriately when a newline appears while reading a $(...) command
+    substitution.
+
+dd. A bug that caused the shell to dump core when `help --' was executed
+    was fixed.
+
+ee. A bug that caused the shell to crash when an unset variable appeared
+    in the body of a here document after `set -u' had been executed was
+    fixed.
+
+ff. Implicit input redirections from /dev/null for asynchronous commands
+    are now handled better.
+
+gg. A bug that caused the shell to fail to compile when configured with
+    `--disable-readline' was fixed.
+
+hh. The globbing code should now be interruptible.
+
+ii. Bash now notices when the `kill' builtin is used to send SIGCONT to a
+    stopped job and adjusts the data structures accordingly, as if `bg' had
+    been executed instead.
+
+jj. A bug that caused the shell to crash when mixing calls to `getopts'
+    and `shift' on the same set of positional parameters was fixed.
+
+kk. The command printing code now preserves the `-p' flag to `time'.
+
+ll. The command printing code now handles here documents better when there
+    are other redirections associated with the command.
+
+mm. The special glibc environment variable (NNN_GNU_nonoption_argv_flags_)
+    is no longer placed into the environment of executed commands -- users
+    of glibc had too many problems with it.
+
+nn. Reorganized the code that generates signames.h.  The signal_names list
+    is now more complete but may be slightly different (SIGABRT is favored
+    over SIGIOT, for example).  The preferred signal names are those
+    listed in the POSIX.2 standard.
+
+oo. `bashbug' now uses a filename shorter than 14 characters for its
+    temporary file, and asks for confirmation before sending the bug
+    report.
+
+pp. A bug that caused TAB completion in vi editing mode to not be turned
+    off when `set -o posix' was executed or back on when `set +o posix'
+    was executed was fixed.
+
+qq. A bug in the brace expansion code that caused brace expansions appearing
+    in new-style $(...) command substitutions to be inappropriately expanded
+    was fixed.
+
+rr. A bug in the readline hook shell-expand-line that could cause memory to
+    be inappropriately freed was fixed.
+
+ss. A bug that caused some arithmetic expressions containing `&&' and `||'
+    to be parsed with the wrong precedence has been fixed.
+
+tt. References to unbound variables after `set -u' has been executed now
+    cause the shell to exit immediately, as they should.
+
+uu. A bug that caused the shell to exit inappropriately when `set -e' had
+    been executed and a command's return status was being inverted with the
+    `!' reserved word was fixed.
+
+vv. A bug that could occasionally cause the shell to crash with a
+    divide-by-zero error when timing a command was fixed.
+
+ww. A bug that caused parameter pattern substitution to leave stray
+    backslashes in the replacement string when the expression is in
+    double quotes was fixed.
+
+xx. The `break' and `continue' builtins now break out of all loops when an
+    invalid count argument is supplied.
+
+yy. Fixed a bug that caused PATH to be set to the empty string if
+    `command -p' is executed with PATH unset.
+
+zz. Fixed `kill -l signum' to print the signal name without the `SIG' prefix,
+    as POSIX specifies.
+
+aaa. Fixed a bug that caused the shell to crash while setting $SHELLOPTS
+     if there were no shell options set.
+
+bbb. Fixed `export -p' and `readonly -p' so that when the shell is in POSIX
+     mode, their output is as POSIX.2 specifies.
+
+ccc. Fixed a bug in `readonly' so that `readonly -a avar=(...)' actually
+     creates an array variable.
+
+ddd. Fixed a bug that prevented `time' from correctly timing background
+     pipelines.
+
+2.  Changes to Readline
+
+a.  A bug that caused an extra newline to be printed when the cursor was on
+    an otherwise empty line was fixed.
+
+b.  An instance of memory being used after it was freed was corrected.
+
+c.  The redisplay code now works when the prompt is longer than the screen
+    width.
+
+d.  `dump-macros' is now a bindable name, as it should have been all along.
+
+e.  Non-printable characters are now expanded when displaying macros and
+    their values.
+
+f.  The `dump-variables' and `dump-macros' commands now output a leading
+    newline if they're called as the result of a key sequence, rather
+    than directly by an application.
+
+3.  New Features in Bash
+
+a.  There is a new builtin array variable: GROUPS, the set of groups to which
+    the user belongs.  This is used by the test suite.
+
+4.  New Features in Readline
+
+a.  If a key sequence bound to `universal-argument' is read while reading a
+    numeric argument started with `universal-argument', it terminates the
+    argument but is otherwise ignored.  This provides a way to insert multiple
+    instances of a digit string, and is how GNU emacs does it.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.0-release,
+and the previous version, bash-2.0-beta3.
+
+1.  Changes to Bash
+
+a.  Fix to the `getopts' builtin so that it does the right thing when a
+    required option argument is not present.
+
+b.  The completion code now updates the common prefix of matched names
+    after FIGNORE processing is done, since any names that were removed
+    may have changed the common prefix.
+
+c.  Fixed a bug that made messages in MAILPATH entries not work correctly.
+
+d.  Fixed a serious documentation error in the description of the new
+    ${parameter:offset[:length]} expansion.
+
+e.  Fixes to make parameter substring expansion ({$param:offset[:length]})
+    work when within double quotes.
+
+f.  Fixes to make ^A (CTLESC) survive an unquoted expansion of positional
+    parameters.
+
+g.  Corrected a misspelling of `unlimited' in the output of `ulimit'.
+
+h.  Fixed a bug that caused executable scripts without a leading `#!' to
+    occasionally pick up the wrong set of positional parameters.
+
+i.  Linux systems now have a working `ulimit -v', using RLIMIT_AS.
+
+j.  Updated config.guess so that many more machine types are recognized.
+
+k.  Fixed a bug with backslash-quoted slashes in the ${param/pat[/sub]}
+    expansion.
+
+l.  If the shell is named `-su', and `-c command' is supplied, read and
+    execute the login shell startup files even though the shell is not
+    interactive.  This is to support the `-' option to `su'.
+
+m.  Fixed a bug that caused core dumps when the DEBUG trap was ignored
+    with `trap "" DEBUG' and a shell function was subsequently executed.
+
+n.  Fixed a bug that caused core dumps in the read builtin when IFS was
+    set to the null string and the input had leading whitespace.
+
+2.  Changes to Readline
+
+a.  Fixed a bug that caused a numeric argument of 1024 to be ignored when
+    inserting text.
+
+b.  Fixed the display code so that the numeric argument is displayed as it's
+    being entered.
+
+c.  Fixed the numeric argument reading code so that `M-- command' is
+    equivalent to `M--1 command', as the prompt implies.
+
+3.  New Features in Bash
+
+a.  `ulimit' now sets both hard and soft limits and reports the soft limit
+    by default (when neither -H nor -S is specified).  This is compatible
+    with versions of sh and ksh that implement `ulimit'.
+
+b.  Integer constants have been extended to base 64.
+
+4.  New Features in Readline
+
+a.  The `home' and `end' keys are now bound to beginning-of-line and
+    end-of-line, respectively, if the corresponding termcap capabilities
+    are present.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.0-beta3,
+and the previous version, bash-2.0-beta2.
+
+1.  Changes to Bash
+
+a.  System-specific changes for: AIX 4.2, SCO 3.2v[45], HP-UX.
+
+b.  When in POSIX mode, variable assignments preceding a special builtin
+    persist in the shell environment after the builtin completes.
+
+c.  Changed all calls to getwd() to getcwd().  Improved check for systems
+    where the libc getcwd() calls popen(), since that breaks on some
+    systems when job control is being used.
+
+d.  Fixed a bug that caused seg faults when executing scripts with the
+    execute bit set but without a leading `#!'.
+
+e.  The environment passed to executed commands is never sorted.
+
+f.  A bug was fixed in the code that expands ${name[@]} to the number of
+    elements in an array variable.
+
+g.  A bug was fixed in the array compound assignment code ( A=( ... ) ).
+
+h.  Window size changes now correctly propagate down to readline if
+    the shopt `checkwinsize' option is enabled.
+
+i.  A fix was made in the code that expands to the length of a variable
+    value (${#var}).
+
+j.  A fix was made to the command builtin so that it did not turn on the
+    `no fork' flag inappropriately.
+
+k.  A fix was made to make `set -n' work more reliably.
+
+l.  A fix was made to the job control initialization code so that the
+    terminal process group is set to the shell's process group if the
+    shell changes its own process group.
+
+2.  Changes to Readline
+
+a.  System-specific changes for: SCO 3.2v[45].
+
+b.  The behavior of the vi-mode `.' when redoing an `i' command was changed
+    to insert the text previously inserted by the `i' command rather than
+    simply entering insert mode.
+
+3.  New features in Bash
+
+a.  There is a new version of the autoload function package, in
+    examples/functions/autoload.v2, that uses arrays and provides more
+    functionality.
+
+b.  Support for LC_COLLATE and locale-specific sorting of the results of
+    pathname expansion if strcoll() is available.
+
+4.  New Features in Readline
+
+a.  Support for locale-specific sorting of completion possibilities if
+    strcoll() is available.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.0-beta2,
+and the previous version, bash-2.0-beta1.
+
+1.  Changes to Bash
+
+a.  `pushd -' is once again equivalent to `pushd $OLDPWD'.
+
+b.  OS-specific changes for: SCO 3.2v[45].
+
+c.  A change was made to the fix for the recently-reported security hole
+    when reading characters with octal value 255 to make it work better on
+    systems with restartable system calls when not using readline.
+
+d.  Some changes were made to the test suite so that it works if you
+    configure bash with --enable-usg-echo-default.
+
+e.  A fix was made to the parsing of conditional arithmetic expressions.
+
+f.  Illegal arithmetic bases now cause an arithmetic evaluation error rather
+    than being silently reset.
+
+g.  Multiple arithmetic bases now cause an arithmetic evaluation error
+    instead of being ignored.
+
+h.  A fix was made to the evaluation of ${param?word} to conform to POSIX.2.
+
+i.  A bug that sometimes caused array indices to be evaluated twice (which
+    would cause errors when they contained assignment statements) was fixed.
+
+j.  `ulimit' was rewritten to avoid problems with getrlimit(2) returning
+    unsigned values and to simplify the code.
+
+k.  A bug in the command-oriented-history code that caused it to sometimes
+    put semicolons after right parens inappropriately was fixed.
+
+l.  The values inserted into the prompt by the \w and \W escape sequences
+    are now quoted to prevent further expansion.
+
+m.  An interactive shell invoked as `sh' now reads and executes commands
+    from the file named by $ENV when it starts up.  If it's a login shell,
+    it does this after reading /etc/profile and ~/.profile.
+
+n.  The file named by $ENV is never read by non-interactive shells.
+
+2.  Changes to Readline
+
+a.  A few changes were made to hide some macros and functions that should not
+    be public.
+
+b.  An off-by-one error that caused seg faults in the history expansion code
+    was fixed.
+
+3.  New Features in Bash
+
+a.  The ksh-style ((...)) arithmetic command was implemented.  It is exactly
+    identical to let "...".  This is controlled by a new option to configure,
+    `--enable-dparen-arithmetic', which is on by default.
+
+b.  There is a new #define available in config.h.top: SYS_BASH_LOGOUT.  If
+    defined to a filename, bash reads and executes commands from that file
+    when a login shell exits.  It's commented out by default.
+
+c.  `ulimit' has a `-l' option that reports the maximum amount of data that
+    may be locked into memory on 4.4BSD-based systems.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.0-beta1,
+and the previous version, bash-2.0-alpha4.
+
+1.  Changes to Bash
+
+a.  A bug that sometimes caused traps to be ignored on signals the
+    shell treats specially was fixed.
+
+b.  The internationalization code was changed to track the values of
+    LC_* variables and call setlocale() as appropriate.  The TEXTDOMAIN
+    and TEXTDOMAINDIR variables are also tracked; changes cause calls
+    to textdomain() and bindtextdomain(), if available.
+
+c.  A bug was fixed that sometimes caused double-quoted strings to be
+    parsed incorrectly.
+
+d.  Changes were made so that the siglist code compiles correctly on
+    Solaris 2.5.
+
+e.  Added `:' to the set of characters that cause word breaks for the
+    completion code so that pathnames in assignments to $PATH can be
+    completed.
+
+f.  The `select' command was fixed to print $PS3 to stderr.
+
+g.  Fixed an error in the manual page section describing the effect that
+    setting and unsetting GLOBIGNORE has on the setting of the `dotglob'
+    option.
+
+h.  The time conversion code now uses CLK_TCK rather than CLOCKS_PER_SEC
+    on systems without gettimeofday() and resources.
+
+i.  The getopt static variables are now initialized each time a subshell
+    is started, so subshells using `getopts' work right.
+
+j.  A sign-extension bug that caused a possible security hole was fixed.
+
+k.  The parser now reads characters between backquotes within a double-
+    quoted string as a single word, so double quotes in the backquoted
+    string don't terminate the enclosing double-quoted string.
+
+l.  A bug that caused `^O' to work incorrectly when typed as the first
+    thing to an interactive shell was fixed.
+
+m.  A rarely-exercised off-by-one error in the code that quotes variable
+    values was fixed.
+
+n.  Some memory and file descriptor leaks encountered when running a
+    shell script that is executable but does not have a leading `#!'
+    were plugged.
+
+2.  Changes to Readline
+
+a.  A bug that sometimes caused incorrect results when trying to read
+    typeahead on systems without FIONREAD was fixed.
+
+3.  New Features in Bash
+
+a.  The command timing code now uses the value of the TIMEFORMAT variable
+    to format and display timing statistics.
+
+b.  The `time' reserved word now accepts a `-p' option to force the
+    POSIX.2 output format.
+
+c.  There are a couple of new and updated scripts to convert csh startup
+    files to bash format.
+
+d.  There is a new builtin array variable: BASH_VERSINFO.  The various
+    members hold the parts of the version information in BASH_VERSION,
+    plus the value of MACHTYPE.
+
+4.  New Features in Readline
+
+a.  Setting LANG to `en_US.ISO8859-1' now causes readline to enter
+    eight-bit mode.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.0-alpha4,
+and the previous version, bash-2.0-alpha3.
+
+1.  Changes to Bash
+
+a.  There is better detection of rsh connections on Solaris 2.
+
+b.  Assignments to read-only variables preceding a command name are now
+    variable assignment errors.  Variable assignment errors cause
+    non-interactive shells running in posix mode to exit.
+
+c.  The word tokenizer was rewritten to handle nested quotes and pairs
+    ('', "", ``, ${...}, $(...), $[...], $'...', $"...", <(...), >(...))
+    correctly.  Some of the parameter expansion code was updated as a
+    consequence.
+
+d.  A fix was made to `test' when given three arguments so that a binary
+    operator is checked for first, before checking that the first argument
+    is `!'.
+
+e.  2''>/dev/null is no longer equivalent to 2>/dev/null.
+
+f.  Parser error messages were regularized, and in most cases the name of
+    the shell script being read by a non-interactive shell is not printed
+    twice.
+
+g.  A fix was made to the completion code so that it no longer removes the
+    text the user typed in some cases.
+
+h.  The special glibc `getopt' environment variable is no longer put into
+    the environment on machines with small values of ARG_MAX.
+
+i.  The expansion of ${...} now follows the POSIX.2 rules for finding the
+    closing `}'.
+
+j.  The shell no longer displays spurious status messages for background
+    jobs in shell scripts that complete successfully when the script is
+    run from a terminal.
+
+k.  `shopt -o' now correctly updates $SHELLOPTS.
+
+l.  A bug that caused the $PATH searching code to return a non-executable
+    file even when an executable file with the same name appeared later in
+    $PATH was fixed.
+
+m.  The shell now does tilde expansions on unquoted `:~' in assignment
+    statements when not in posix mode.
+
+n.  Variable assignment errors when a command consists only of assignments
+    now cause non-interactive shells to exit when in posix mode.
+
+o.  If the variable in a `for' or `select' command is read-only, or not a
+    legal shell identifier, a variable assignment error occurs.
+
+p.  `test' now handles `-a' and `-o' as binary operators when three arguments
+    are supplied, and correctly parses `( word )' as equivalent to `word'.
+
+q.  `test' was fixed so that file names of the form /dev/fd/NN mean the same
+    thing on all systems, even Linux.
+
+r.  Fixed a bug in the globbing code that caused patterns with multiple
+    consecutive `*'s to not be matched correctly.
+
+s.  Fixed a bug that caused $PS2 to not be printed when an interactive shell
+    not using readline is reading a here document.
+
+t.  Fixed a bug that caused history expansion to be performed inappropriately
+    when a single-quoted string spanned more than one line.
+
+u.  `getopts' now checks that the variable name passed by the user as the
+    second argument is a legal shell identifier and that the variable is
+    not read-only.
+
+v.  Fixed `getopts' to obey POSIX.2 rules for setting $OPTIND when it
+    encounters an error.
+
+w.  Fixed `set' to display variable values in a form that can be re-read.
+
+x.  Fixed a bug in the code that keeps track of whether or not local variables
+    have been declared at the current level of function nesting.
+
+y.  Non-interactive shells in posix mode now exit if the name in a function
+    declaration is not a legal identifier.
+
+z.  The job control code now ignores stopped children when the shell is not
+    interactive.
+
+aa. The `cd' builtin no longer attempts spelling correction on the directory
+    name if the shell is not interactive, regardless of the setting of the
+    `cdspell' option.
+
+bb. Some OS-specific changes were made for SCO 3.2v[45] and AIX 4.2.
+
+cc. `time' now prints its output to stderr, as POSIX.2 specifies.
+
+2.  Fixes to Readline
+
+a.  After printing possible completions, all lines of a multi-line prompt
+    are redisplayed.
+
+b.  Some changes were made to the terminal handling code in rltty.c to
+    work around AIX 4.2 bugs.
+
+3.  New Features in Bash
+
+a.  There is a new loadable builtin: sprintf, with calling syntax
+		sprintf var format [args]
+    This provides an easy way to simulate ksh left- and right-justified
+    variable values.
+
+b.  The expansions of \h and \H in prompt strings were swapped.  \h now
+    expands to the hostname up to the first `.', as in bash-1.14.
+
+4.  New Features in Readline
+
+a.  The bash-1.14 behavior when ^M is typed while doing an incremental
+    search was restored.  ^J may now be used to terminate the search without
+    accepting the line.
+
+b.  There is a new bindable variable: disable-completion.  This inhibits
+    word completion and causes the completion character to be inserted as
+    if it had been bound to self-insert.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.0-alpha3,
+and the previous version, bash-2.0-alpha2.
+
+There is now a file `COMPAT' included in the distribution that lists the
+user-visible incompatibilities between 1.14 and 2.0.
+
+1. Changes to Bash
+
+a. Some work was done so that word splitting of the rhs of assignment
+   statements conforms more closely to historical practice.
+
+b. A couple of errant memory frees were fixed.
+
+c. A fix was made to the test builtin so it recognizes `<' and `>' as
+   binary operators.
+
+d. The GNU malloc in lib/malloc/malloc.c now scrambles memory as it's
+   allocated and freed.  This is to catch callers that refer to freed
+   memory or assume something about newly-allocated memory.
+
+e. Fixed a problem with conversion to 12-hour time in the prompt
+   expansion code.
+
+f. Fixed a problem with configure's argument parsing order.  Now you can
+   correctly turn on specific options after using --enable-minimal-config.
+
+g. The configure script now automatically disables the use of GNU malloc
+   on systems where it's appropriate (better than having people read the
+   NOTES file and do it manually).
+
+h. There are new prompt expansions (\v and \V) to insert version information
+   into the prompt strings.
+
+i. The default prompt string now includes the version number.
+
+j. Most of the builtins that take no options were changed to use the
+   internal getopt so they can produce proper error messages for -?
+   and incorrect options.
+
+k. Some system-specific changes were made for SVR4.2 and Solaris 2.5.
+
+l. Bash now uses PATH_MAX instead of MAXPATHLEN and NAME_MAX instead of
+   MAXNAMLEN.
+
+m. A couple of problems caused by uninitialized variables were fixed.
+
+n. There are a number of new loadable builtin examples: logname, basename,
+   dirname, tty, pathchk, tee, head, and rmdir.  All of these conform to
+   POSIX.2.
+
+o. Bash now notices changes in TZ and calls tzset() if present, so
+   changing TZ will alter the time printed by prompt expansions.
+
+p. The source was reorganized a bit so I don't have to wait so long for
+   some files to compile, and to facilitate the creation of a `shell
+   library' at some future point.
+
+q. Bash no longer turns off job control if called as `sh', since the
+   POSIX.2 spec includes job control as a standard feature.
+
+r. `bash -o posix' now works as intended.
+
+s. Fixed a problem with the completion code: when completing a filename
+   that contained globbing characters, if show-all-if-ambiguous was set,
+   the completion code would remove the user's text.
+
+t. Fixed ulimit so that (hopefully) the full range of limits is available
+   on HPUX systems.
+
+u. A new `shopt' option (`hostcomplete') enables and disables hostname
+   completion.
+
+v. The shell no longer attempts to save the history on an abort(),
+   which is usually called by programming_error().
+
+w. The `-s' option to `fc' was changed to echo the command to be executed
+   to stderr instead of stdout.
+
+x. If the editor invoked by `fc -e' exits with a non-zero status, no
+   commands are executed.
+
+y. Fixed a bug that made the shopt `histverify' option work incorrectly.
+
+z. There is a new variable `MACHTYPE' whose value is the GNU-style
+   `cpu-company-system' system description as set by configure.  (The
+   values of MACHTYPE and HOSTTYPE should really be swapped.)
+
+aa. The `ulimit' builtin now allows the maximum virtual memory size to be
+    set via setrlimit(2) if RLIMIT_VMEM is defined.
+
+bb. `bash -nc 'command'' no longer runs `command'.
+
+2. Changes to Readline
+
+a. Fixed a typo in the code that checked for FIONREAD in input.c.
+
+b. Fixed a bug in the code that outputs keybindings, so things like C-\
+   are quoted properly.
+
+c. Fixed a bug in the inputrc file parsing code to handle the problems
+   caused by inputrc files created from the output of `bind -p' in
+   previous versions of bash.  The problem was due to the bug fixed
+   in item b above.
+
+d. Readline no longer turns off the terminal's meta key, and turns it on
+   once the first time it's called.
+
+------------------------------------------------------------------------------
+This file documents the changes between this version, bash-2.0-alpha2,
+and the previous version, bash-2.0-alpha.
+
+1. Changes to Bash
+
+a. The shell no longer thinks directories are executable.
+
+b. `disown' has a new option, `h', which inhibits the resending of SIGHUP
+   but does not remove the job from the jobs table.
+
+c. The varargs functions in error.c now use ANSI-C `stdarg' if available.
+
+d. The build process now treats the `build version' in .build as local to
+   the build directory, so different versions built from the same source
+   tree have different `build versions'.
+
+e. Some problems with the grammar have been fixed. (It used `list' in a few
+   productions where `compound_list' was needed.  A `list' must be terminated
+   with a newline or semicolon; a `compound_list' need not be.)
+
+f. A fix was made to keep `wait' from hanging when waiting for all background
+   jobs.
+
+g. `bash --help' now writes its output to stdout, like the GNU Coding Standards
+   specify, and includes the machine type (the value of MACHTYPE).
+
+h. `bash --version' now prints more information and exits successfully, like
+   the GNU Coding Standards specify.
+
+i. The output of `time' and `times' now prints fractional seconds with three
+   places after the decimal point.
+
+j. A bug that caused process substitutions to screw up the pipeline printed
+   by `jobs' was fixed.
+
+k. Fixes were made to the code that implements $'...' and $"..." so they
+   work as documented.
+
+l. The process substitution code now opens named pipes for reading with
+   O_NONBLOCK to avoid hanging.
+
+m. Fixes were made to the trap code so the shell cleans up correctly if the
+   trap command contains a `return' and we're executing a function or
+   sourcing a script with `.'.
+
+n. Fixes to doc/Makefile.in so that it doesn't try to remake all of the
+   documentation (ps, dvi, etc.) on a `make install'.
+
+o. Fixed an auto-increment error that caused bash -c args to sometimes dump
+   core.
+
+p. Fixed a bug that caused $HISTIGNORE to fail when the history line
+   contained globbing characters.
+
+2. Changes to Readline
+
+a. There is a new string variable, rl_library_version, available for use by
+   applications.  The current value is "2.1".
+
+b. A bug encountered when expand-tilde was enabled and file completion was
+   attempted on a word beginning with `~/' was fixed.
+
+c. A slight change was made to the incremental search termination behavior.
+   ESC still terminates the search, but if input is pending or arrives
+   within 0.1 seconds (on systems with select(2)), it is used as a prefix
+   character.  This is intended to allow users to terminate searches with
+   the arrow keys and get the behavior they expect.

+Compatibility with previous versions
+====================================
+
+This document details the incompatibilities between this version of bash,
+bash-5.2, and the previous widely-available versions, bash-3.2 (which is
+still the `standard' version for Mac OS X), 4.2/4.3 (which are still
+standard on a few Linux distributions), and bash-4.4/bash-5.0/bash-5.1,
+the current widely-available versions.  These were discovered by users of
+bash-2.x through 5.x, so this list is not comprehensive.  Some of these
+incompatibilities occur between the current version and versions 2.0 and
+above. 
+
+1.  Bash uses a new quoting syntax, $"...", to do locale-specific
+    string translation.  Users who have relied on the (undocumented)
+    behavior of bash-1.14 will have to change their scripts.  For
+    instance, if you are doing something like this to get the value of
+    a variable whose name is the value of a second variable:
+
+	eval var2=$"$var1"
+
+    you will have to change to a different syntax.
+
+    This capability is directly supported by bash-2.0:
+
+	var2=${!var1}
+
+    This alternate syntax will work portably between bash-1.14 and bash-2.0:
+
+	eval var2=\$${var1}
+
+2.  One of the bugs fixed in the YACC grammar tightens up the rules
+    concerning group commands ( {...} ).  The `list' that composes the
+    body of the group command must be terminated by a newline or
+    semicolon.  That's because the braces are reserved words, and are
+    recognized as such only when a reserved word is legal.  This means
+    that while bash-1.14 accepted shell function definitions like this:
+
+	foo() { : }
+
+    bash-2.0 requires this:
+
+	foo() { :; }
+
+    This is also an issue for commands like this:
+
+	mkdir dir || { echo 'could not mkdir' ; exit 1; }
+
+    The syntax required by bash-2.0 is also accepted by bash-1.14.
+
+3.  The options to `bind' have changed to make them more consistent with
+    the rest of the bash builtins.  If you are using `bind -d' to list
+    the readline key bindings in a form that can be re-read, use `bind -p'
+    instead.  If you were using `bind -v' to list the key bindings, use
+    `bind -P' instead.
+
+4.  The `long' invocation options must now be prefixed by `--' instead
+    of `-'.  (The old form is still accepted, for the time being.)
+
+5.  There was a bug in the version of readline distributed with bash-1.14
+    that caused it to write badly-formatted key bindings when using 
+    `bind -d'.  The only key sequences that were affected are C-\ (which
+    should appear as \C-\\ in a key binding) and C-" (which should appear
+    as \C-\").  If these key sequences appear in your inputrc, as, for
+    example,
+
+	"\C-\": self-insert
+
+    they will need to be changed to something like the following:
+
+	"\C-\\": self-insert
+
+6.  A number of people complained about having to use ESC to terminate an
+    incremental search, and asked for an alternate mechanism.  Bash-2.03
+    uses the value of the settable readline variable `isearch-terminators'
+    to decide which characters should terminate an incremental search.  If
+    that variable has not been set, ESC and Control-J will terminate a
+    search.
+
+7.  Some variables have been removed:  MAIL_WARNING, notify, history_control,
+    command_oriented_history, glob_dot_filenames, allow_null_glob_expansion,
+    nolinks, hostname_completion_file, noclobber, no_exit_on_failed_exec, and
+    cdable_vars.  Most of them are now implemented with the new `shopt'
+    builtin; others were already implemented by `set'.  Here is a list of
+    correspondences:
+
+	MAIL_WARNING			shopt mailwarn
+	notify				set -o notify
+	history_control			HISTCONTROL
+	command_oriented_history	shopt cmdhist
+	glob_dot_filenames		shopt dotglob
+	allow_null_glob_expansion	shopt nullglob
+	nolinks				set -o physical
+	hostname_completion_file	HOSTFILE
+	noclobber			set -o noclobber
+	no_exit_on_failed_exec		shopt execfail
+	cdable_vars			shopt cdable_vars
+
+8. `ulimit' now sets both hard and soft limits and reports the soft limit
+    by default (when neither -H nor -S is specified).  This is compatible
+    with versions of sh and ksh that implement `ulimit'.  The bash-1.14
+    behavior of, for example,
+
+		ulimit -c 0
+
+    can be obtained with
+
+		ulimit -S -c 0
+
+    It may be useful to define an alias:
+
+		alias ulimit="ulimit -S"
+
+9.  Bash-2.01 uses a new quoting syntax, $'...' to do ANSI-C string
+    translation.  Backslash-escaped characters in ... are expanded and
+    replaced as specified by the ANSI C standard.
+
+10. The sourcing of startup files has changed somewhat.  This is explained
+    more completely in the INVOCATION section of the manual page.
+
+    A non-interactive shell not named `sh' and not in posix mode reads
+    and executes commands from the file named by $BASH_ENV.  A
+    non-interactive shell started by `su' and not in posix mode will read
+    startup files.  No other non-interactive shells read any startup files.
+
+    An interactive shell started in posix mode reads and executes commands
+    from the file named by $ENV.
+
+11. The <> redirection operator was changed to conform to the POSIX.2 spec.
+    In the absence of any file descriptor specification preceding the `<>',
+    file descriptor 0 is used.  In bash-1.14, this was the behavior only
+    when in POSIX mode.  The bash-1.14 behavior may be obtained with
+
+	<>filename 1>&0
+
+12. The `alias' builtin now checks for invalid options and takes a `-p'
+    option to display output in POSIX mode.  If you have old aliases beginning
+    with `-' or `+', you will have to add the `--' to the alias command
+    that declares them:
+
+	alias -x='chmod a-x' --> alias -- -x='chmod a-x'
+
+13. The behavior of range specificiers within bracket matching expressions
+    in the pattern matcher (e.g., [A-Z]) depends on the current locale,
+    specifically the value of the LC_COLLATE environment variable.  Setting
+    this variable to C or POSIX will result in the traditional ASCII behavior
+    for range comparisons.  If the locale is set to something else, e.g.,
+    en_US (specified by the LANG or LC_ALL variables), collation order is
+    locale-dependent.  For example, the en_US locale sorts the upper and
+    lower case letters like this:
+
+	AaBb...Zz
+
+    so a range specification like [A-Z] will match every letter except `z'.
+    Other locales collate like
+
+        aAbBcC...zZ
+
+    which means that [A-Z] matches every letter except `a'.
+
+    The portable way to specify upper case letters is [:upper:] instead of
+    A-Z; lower case may be specified as [:lower:] instead of a-z.
+
+    Look at the manual pages for setlocale(3), strcoll(3), and, if it is
+    present, locale(1).
+
+    You can find your current locale information by running locale(1):
+
+	caleb.ins.cwru.edu(2)$ locale
+	LANG=en_US
+	LC_CTYPE="en_US"
+	LC_NUMERIC="en_US"
+	LC_TIME="en_US"
+	LC_COLLATE="en_US"
+	LC_MONETARY="en_US"
+	LC_MESSAGES="en_US"
+	LC_ALL=en_US
+
+    My advice is to put
+
+	export LC_COLLATE=C
+
+    into /etc/profile and inspect any shell scripts run from cron for
+    constructs like [A-Z].  This will prevent things like
+
+	rm [A-Z]*
+
+    from removing every file in the current directory except those beginning
+    with `z' and still allow individual users to change the collation order.
+    Users may put the above command into their own profiles as well, of course.
+
+14. Bash versions up to 1.14.7 included an undocumented `-l' operator to
+    the `test/[' builtin.  It was a unary operator that expanded to the
+    length of its string argument.  This let you do things like
+
+	test -l $variable -lt 20
+
+    for example.
+
+    This was included for backwards compatibility with old versions of the
+    Bourne shell, which did not provide an easy way to obtain the length of
+    the value of a shell variable.
+
+    This operator is not part of the POSIX standard, because one can (and
+    should) use ${#variable} to get the length of a variable's value.
+    Bash-2.x does not support it.
+
+15. Bash no longer auto-exports the HOME, PATH, SHELL, TERM, HOSTNAME,
+    HOSTTYPE, MACHTYPE, or OSTYPE variables.  If they appear in the initial
+    environment, the export attribute will be set, but if bash provides a
+    default value, they will remain local to the current shell.
+
+16. Bash no longer initializes the FUNCNAME, GROUPS, or DIRSTACK variables
+    to have special behavior if they appear in the initial environment.
+
+17. Bash no longer removes the export attribute from the SSH_CLIENT or
+    SSH2_CLIENT variables, and no longer attempts to discover whether or
+    not it has been invoked by sshd in order to run the startup files.
+
+18. Bash no longer requires that the body of a function be a group command;
+    any compound command is accepted.
+
+19. As of bash-3.0, the pattern substitution operators no longer perform
+    quote removal on the pattern before attempting the match.  This is the
+    way the pattern removal functions behave, and is more consistent.
+
+20. After bash-3.0 was released, I reimplemented tilde expansion, incorporating
+    it into the mainline word expansion code.  This fixes the bug that caused
+    the results of tilde expansion to be re-expanded.  There is one
+    incompatibility:  a ${paramOPword} expansion within double quotes will not
+    perform tilde expansion on WORD.  This is consistent with the other
+    expansions, and what POSIX specifies.
+
+21. A number of variables have the integer attribute by default, so the +=
+    assignment operator returns expected results: RANDOM, LINENO, MAILCHECK,
+    HISTCMD, OPTIND.
+
+22. Bash-3.x is much stricter about $LINENO correctly reflecting the line
+    number in a script; assignments to LINENO have little effect.
+
+23. By default, readline binds the terminal special characters to their
+    readline equivalents.  As of bash-3.1/readline-5.1, this is optional and
+    controlled by the bind-tty-special-chars readline variable.
+
+24. The \W prompt string expansion abbreviates $HOME as `~'.  The previous
+    behavior is available with ${PWD##/*/}.
+
+25. The arithmetic exponentiation operator is right-associative as of bash-3.1.
+
+26. The rules concerning valid alias names are stricter, as per POSIX.2.
+
+27. The Readline key binding functions now obey the convert-meta setting active
+    when the binding takes place, as the dispatch code does when characters
+    are read and processed.
+
+28. The historical behavior of `trap' reverting signal disposition to the
+    original handling in the absence of a valid first argument is implemented
+    only if the first argument is a valid signal number.
+
+29. In versions of bash after 3.1, the ${parameter//pattern/replacement}
+    expansion does not interpret `%' or `#' specially.  Those anchors don't
+    have any real meaning when replacing every match.
+
+30. Beginning with bash-3.1, the combination of posix mode and enabling the
+    `xpg_echo' option causes echo to ignore all options, not looking for `-n'
+
+31. Beginning with bash-3.2, bash follows the Bourne-shell-style (and POSIX-
+    style) rules for parsing the contents of old-style backquoted command
+    substitutions.  Previous versions of bash attempted to recursively parse
+    embedded quoted strings and shell constructs; bash-3.2 uses strict POSIX
+    rules to find the closing backquote and simply passes the contents of the
+    command substitution to a subshell for parsing and execution.
+
+32. Beginning with bash-3.2, bash uses access(2) when executing primaries for
+    the test builtin and the [[ compound command, rather than looking at the
+    file permission bits obtained with stat(2).  This obeys restrictions of
+    the file system (e.g., read-only or noexec mounts) not available via stat.
+
+33. Bash-3.2 adopts the convention used by other string and pattern matching
+    operators for the `[[' compound command, and matches any quoted portion
+    of the right-hand-side argument to the =~ operator as a string rather
+    than a regular expression.
+
+34. Bash-4.0 allows the behavior in the previous item to be modified using
+    the notion of a shell `compatibility level'.  If the compat31 shopt
+    option is set, quoting the pattern has no special effect.
+
+35. Bash-3.2 (patched) and Bash-4.0 fix a bug that leaves the shell in an
+    inconsistent internal state following an assignment error.  One of the
+    changes means that compound commands or { ... } grouping commands are
+    aborted under some circumstances in which they previously were not.
+    This is what Posix specifies.
+
+36. Bash-4.0 now allows process substitution constructs to pass unchanged
+    through brace expansion, so any expansion of the contents will have to be
+    separately specified, and each process substitution will have to be
+    separately entered.
+
+37. Bash-4.0 now allows SIGCHLD to interrupt the wait builtin, as Posix
+    specifies, so the SIGCHLD trap is no longer always invoked once per
+    exiting child if you are using `wait' to wait for all children.  As
+    of bash-4.2, this is the status quo only when in posix mode.
+
+38. Since bash-4.0 now follows Posix rules for finding the closing delimiter
+    of a $() command substitution, it will not behave as previous versions
+    did, but will catch more syntax and parsing errors before spawning a
+    subshell to evaluate the command substitution.
+
+39. The programmable completion code uses the same set of delimiting characters
+    as readline when breaking the command line into words, rather than the
+    set of shell metacharacters, so programmable completion and readline
+    should be more consistent.
+
+40. When the read builtin times out, it attempts to assign any input read to
+    specified variables, which also causes variables to be set to the empty
+    string if there is not enough input.  Previous versions discarded the
+    characters read.
+
+41. Beginning with bash-4.0, when one of the commands in a pipeline is killed
+    by a SIGINT while executing a command list, the shell acts as if it
+    received the interrupt.  This can be disabled by setting the compat31 or
+    compat32 shell options.
+
+42. Bash-4.0 changes the handling of the set -e option so that the shell exits
+    if a pipeline fails (and not just if the last command in the failing
+    pipeline is a simple command).  This is not as Posix specifies.  There is
+    work underway to update this portion of the standard; the bash-4.0
+    behavior attempts to capture the consensus at the time of release.
+
+43. Bash-4.0 fixes a Posix mode bug that caused the . (source) builtin to
+    search the current directory for its filename argument, even if "." is
+    not in $PATH.  Posix says that the shell shouldn't look in $PWD in this
+    case.
+
+44. Bash-4.1 uses the current locale when comparing strings using the < and
+    > operators to the `[[' command.  This can be reverted to the previous
+    behavior (ASCII collating and strcmp(3)) by setting one of the
+    `compatNN' shopt options, where NN is less than 41.
+
+45. Bash-4.1 conforms to the current Posix specification for `set -u':
+    expansions of $@ and $* when there are no positional parameters do not
+    cause the shell to exit.
+
+46. Bash-4.1 implements the current Posix specification for `set -e' and
+    exits when any command fails, not just a simple command or pipeline.
+
+47. Command substitutions now remove the caller's trap strings when trap is
+    run to set a new trap in the subshell.  Previous to bash-4.2, the old
+    trap strings persisted even though the actual signal handlers were reset.
+
+48. When in Posix mode, a single quote is not treated specially in a
+    double-quoted ${...} expansion, unless the expansion operator is
+    # or % or the new `//', `^', or `,' expansions.  In particular, it
+    does not define a new quoting context.  This is from Posix interpretation
+    221.
+
+49. Posix mode shells no longer exit if a variable assignment error occurs
+    with an assignment preceding a command that is not a special builtin.
+
+50. Bash-4.2 attempts to preserve what the user typed when performing word
+    completion, instead of, for instance, expanding shell variable
+    references to their value.
+
+51. When in Posix mode, bash-4.2 exits if the filename supplied as an argument
+    to `.' is not found and the shell is not interactive.
+
+52. When compiled for strict Posix compatibility, bash-4.3 does not enable
+    history expansion by default in interactive shells, since it results in
+    a non-conforming environment.
+
+53. Bash-4.3 runs the replacement string in the pattern substitution word
+    expansion through quote removal.  The code already treats quote
+    characters in the replacement string as special; if it treats them as
+    special, then quote removal should remove them.
+
+54. Bash-4.4 no longer considers a reference to ${a[@]} or ${a[*]}, where `a'
+    is an array without any elements set, to be a reference to an unset
+    variable.  This means that such a reference will not cause the shell to
+    exit when the `-u' option is enabled.
+
+55. Bash-4.4 allows double quotes to quote the history expansion character (!)
+    when in Posix mode, since Posix specifies the effects of double quotes.
+
+56. Bash-4.4 does not inherit $PS4 from the environment if running as root.
+
+57. Bash-4.4 doesn't allow a `break' or `continue' in a function to affect
+    loop execution in the calling context.
+
+58. Bash-4.4 no longer expands tildes in $PATH elements when in Posix mode.
+
+59. Bash-4.4 does not attempt to perform a compound array assignment if an
+    argument to `declare' or a similar builtin expands to a word that looks
+    like a compound array assignment (e.g. declare w=$x where x='(foo)').
+
+60. Bash-5.0 only sets up BASH_ARGV and BASH_ARGC at startup if extended
+    debugging mode is active. The old behavior of unconditionally setting
+    BASH_ARGC and BASH_ARGV is available at compatibility levels less than
+    or equal to 44.
+
+61. Bash-5.0 doesn't allow a `break' or `continue' in a subshell to attempt
+    to break or continue loop execution inherited from the calling context.
+
+62. Bash-5.0 doesn't allow variable assignments preceding builtins like
+    export and readonly to modify variables with the same name in preceding
+    contexts (including the global context) unless the shell is in posix
+    mode, since export and readonly are special builtins.
+
+63. Bash-5.1 changes the way posix-mode shells handle assignment statements
+    preceding shell function calls. Previous versions of POSIX specified that
+    such assignments would persist after the function returned; subsequent
+    versions of the standard removed that requirement (interpretation #654).
+    Bash-5.1 posix mode assignment statements preceding shell function calls
+    do not persist after the function returns.
+
+64. Bash-5.1 reverts to the bash-4.4 treatment of pathname expansion of words
+    containing backslashes but no other special globbing characters. This comes
+    after a protracted discussion and a POSIX interpretation (#1234).
+
+65. In bash-5.1, disabling posix mode attempts to restore the state of several
+    options that posix mode modifies to the state they had before enabling
+    posix mode. Previous versions restored these options to default values.
+
+66. Bash-5.2 attempts to prevent double-expansion of array subscripts under
+    certain circumstances, especially arithmetic evaluation, by acting as if
+    the `assoc_expand_once' shell option were set.
+
+67. The `unset' builtin in bash-5.2 treats array subscripts `@' and `*'
+    differently than previous versions, and differently depending on whether
+    the array is indexed or associative.
+
+
+Shell Compatibility Level
+=========================
+
+Bash-4.0 introduced the concept of a `shell compatibility level', specified
+as a set of options to the shopt builtin (compat31, compat32, compat40,
+compat41, and so on).  There is only one current compatibility level --
+each option is mutually exclusive.  The compatibility level is intended to
+allow users to select behavior from previous versions that is incompatible
+with newer versions while they migrate scripts to use current features and
+behavior.  It's intended to be a temporary solution. 
+
+This section does not mention behavior that is standard for a particular
+version (e.g., setting compat32 means that quoting the rhs of the regexp
+matching operator quotes special regexp characters in the word, which is
+default behavior in bash-3.2 and above). 
+
+If a user enables, say, compat32, it may affect the behavior of other
+compatibility levels up to and including the current compatibility level. 
+The idea is that each compatibility level controls behavior that changed in
+that version of bash, but that behavior may have been present in earlier
+versions.  For instance, the change to use locale-based comparisons with
+the `[[' command came in bash-4.1, and earlier versions used ASCII-based
+comparisons, so enabling compat32 will enable ASCII-based comparisons as
+well.  That granularity may not be sufficient for all uses, and as a result
+users should employ compatibility levels carefully.  Read the documentation
+for a particular feature to find out the current behavior. 
+
+Bash-4.3 introduced a new shell variable: BASH_COMPAT. The value assigned
+to this variable (a decimal version number like 4.2, or an integer
+corresponding to the compatNN option, like 42) determines the compatibility
+level.
+
+Starting with bash-4.4, bash has begun deprecating older compatibility
+levels.  Eventually, the options will be removed in favor of the
+BASH_COMPAT variable. 
+
+Bash-5.0 is the final version for which there will be an individual shopt
+option for the previous version.  Users should use the BASH_COMPAT variable
+on bash-5.0 and later versions. 
+
+The following table describes the behavior changes controlled by each
+compatibility level setting.  The `compatNN' tag is used as shorthand for
+setting the compatibility level to NN using one of the following
+mechanisms.  For versions prior to bash-5.0, the compatibility level may be
+set using the corresponding compatNN shopt option.  For bash-4.3 and later
+versions, the BASH_COMPAT variable is preferred, and it is required for
+bash-5.1 and later versions. 
+
+compat31
+	- the < and > operators to the [[ command do not consider the current
+	  locale when comparing strings; they use ASCII ordering
+	- quoting the rhs of the [[ command's regexp matching operator (=~)
+	  has no special effect
+
+compat32
+	- the < and > operators to the [[ command do not consider the current
+	  locale when comparing strings; they use ASCII ordering
+	- interrupting a command list such as "a ; b ; c" causes the execution
+	  of the next command in the list (in bash-4.0 and later versions,
+	  the shell acts as if it received the interrupt, so interrupting
+	  one command in a list aborts the execution of the entire list)
+
+compat40
+	- the < and > operators to the [[ command do not consider the current
+	  locale when comparing strings; they use ASCII ordering.
+	  Bash versions prior to bash-4.1 use ASCII collation and strcmp(3);
+	  bash-4.1 and later use the current locale's collation sequence and
+	  strcoll(3).
+
+compat41
+	- in posix mode, `time' may be followed by options and still be
+	  recognized as a reserved word (this is POSIX interpretation 267)
+	- in posix mode, the parser requires that an even number of single
+	  quotes occur in the `word' portion of a double-quoted ${...}
+	  parameter expansion and treats them specially, so that characters
+	  within the single quotes are considered quoted (this is POSIX
+	  interpretation 221)
+
+compat42
+	- the replacement string in double-quoted pattern substitution is not
+	  run through quote removal, as it is in versions after bash-4.2
+	- in posix mode, single quotes are considered special when expanding
+	  the `word' portion of a double-quoted ${...} parameter expansion
+	  and can be used to quote a closing brace or other special character
+	  (this is part of POSIX interpretation 221); in later versions,
+	  single quotes are not special within double-quoted word expansions
+
+compat43
+	- the shell does not print a warning message if an attempt is made to
+	  use a quoted compound assignment as an argument to declare
+	  (declare -a foo='(1 2)'). Later versions warn that this usage is
+	  deprecated.
+	- word expansion errors are considered non-fatal errors that cause the
+	  current command to fail, even in posix mode (the default behavior is
+	  to make them fatal errors that cause the shell to exit)
+	- when executing a shell function, the loop state (while/until/etc.)
+	  is not reset, so `break' or `continue' in that function will break
+	  or continue loops in the calling context. Bash-4.4 and later reset
+	  the loop state to prevent this
+
+compat44
+	- the shell sets up the values used by BASH_ARGV and BASH_ARGC so
+	  they can expand to the shell's positional parameters even if extended
+	  debug mode is not enabled
+	- a subshell inherits loops from its parent context, so `break'
+	  or `continue' will cause the subshell to exit. Bash-5.0 and later
+	  reset the loop state to prevent the exit
+	- variable assignments preceding builtins like export and readonly
+	  that set attributes continue to affect variables with the same
+	  name in the calling environment even if the shell is not in posix
+	  mode
+
+compat50 (set using BASH_COMPAT)
+	- Bash-5.1 changed the way $RANDOM is generated to introduce slightly
+	  more randomness. If the shell compatibility level is set to 50 or
+	  lower, it reverts to the method from bash-5.0 and previous versions,
+	  so seeding the random number generator by assigning a value to
+	  RANDOM will produce the same sequence as in bash-5.0
+	- If the command hash table is empty, bash versions prior to bash-5.1
+	  printed an informational message to that effect even when writing
+	  output in a format that can be reused as input (-l). Bash-5.1
+	  suppresses that message if -l is supplied
+	- Bash-5.1 and later use pipes for here-documents and here-strings if
+	  they are smaller than the pipe capacity. If the shell compatibility
+	  level is set to 50 or lower, it reverts to using temporary files.
+
+compat51 (set using BASH_COMPAT)
+	- The `unset' builtin will unset the array a given an argument like
+	  `a[@]'. Bash-5.2 will unset an element with key `@' (associative
+	  arrays) or remove all the elements without unsetting the array
+	  (indexed arrays)
+	- arithmetic commands ( ((...)) ) and the expressions in an arithmetic
+	  for statement can be expanded more than once
+	- expressions used as arguments to arithmetic operators in the [[
+	  conditional command can be expanded more than once
+	- indexed and associative array subscripts used as arguments to the
+	  operators in the [[ conditional command (e.g., `[[ -v') can be
+	  expanded more than once. Bash-5.2 behaves as if the
+	  `assoc_expand_once' option were enabled.
+	- the expressions in substring parameter brace expansion can be
+	  expanded more than once
+	- the expressions in the $(( ... )) word expansion can be expanded
+	  more than once
+	- arithmetic expressions used as indexed array subscripts can be
+	  expanded more than once;
+	- `test -v', when given an argument of A[@], where A is an existing
+	  associative array, will return true if the array has any set
+	  elements. Bash-5.2 will look for a key named `@';
+	- the ${param[:]=value} word expansion will return VALUE, before any
+	  variable-specific transformations have been performed (e.g.,
+	  converting to lowercase). Bash-5.2 will return the final value
+	  assigned to the variable, as POSIX specifies;
+	- Parsing command substitutions will act as if extended glob is
+	  enabled, so that parsing a command substitution containing an extglob
+	  pattern (say, as part of a shell function) will not fail. This
+	  assumes the intent is to enable extglob before the command is
+	  executed and word expansions are performed. It will fail at word
+	  expansion time if extglob hasn't been enabled by the time the
+	  command is executed.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+

+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR

+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read

+				 ---------
+
+[bash-5.1 released]
+
+				   12/7
+				   ----
+Makefile.in
+	- bashline.o: add dependency on ${DEFDIR}/builtext.h. Report from
+	  Fazal Majid <fazal@majid.org>
+
+				   12/11
+				   -----
+builtins/wait.def
+	- wait_builtin: don't assign the variable given with -p if there are no
+	  jobs to wait for. Report and fix from OÄuz <oguzismailuysal@gmail.com>
+
+arrayfunc.c
+	- kvpair_assignment_p: return non-zero if argument L appears to be a
+	  key-value pair associative array compound assignment
+	- expand_and_quote_kvpair_word: run a single word in a key-value pair
+	  associative array compound assignment through the appropriate
+	  expansions and single-quote the result
+
+arrayfunc.h
+	- kvpair_assignment_p, expand_and_quote_kvpair_word: extern declarations
+
+subst.c
+	- expand_oneword: detect whether VALUE appears to be a key-value
+	  pair compound assignment and call the appropriate function to expand
+	  each word in the resulting list. Fixes inconsistency reported by
+	  oguzismailuysal@gmail.com
+
+				   12/12
+				   -----
+subst.c
+	- command_substitute: don't reset pipeline_pgrp to shell_pgrp if we
+	  are already forked to run a command (SUBSHELL_FORK). Fixes SIGINT
+	  in command substitution in here-document in forked child issue
+	  reported by oguzismailuysal@gmail.com
+
+				   12/18
+				   -----
+execute_cmd.c
+	- execute_pipeline: execute the lastpipe code even if prev == 0. It
+	  can only be 0 here if stdin was closed when this function was
+	  executed
+	- execute_pipeline: if prev == 0, set lstdin to a sentinel (-1) that
+	  means to close fd 0 after executing the command, and call close(prev)
+	  before restoring stdin. restore_stdin now understands -1, and closes
+	  fd 0. Fixes issue reported by Tomas Janousek <tomi@nomi.cz>
+
+				   12/21
+				   -----
+doc/bashref.texi
+	- PROMPT_COMMANDS: clean up a couple of remaining instances of this
+	  name. Report from Eli Schwartz <eschwartz@archlinux.org>
+
+				   12/26
+				   -----
+subst.c
+	- command_substitute: make sure that the child process always has
+	  pipeline_pgrp == shell_pgrp: if pipeline_pgrp is non-zero when we
+	  get to the child, meaning that we're part of an already-forked
+	  child that is, for instance, running redirections, we need to reset
+	  shell_pgrp to it to preserve the invariant. Fixes bug with terminal
+	  being set to the incorrect pgrp reported by oguzismailuysal@gmail.com
+
+				   12/29
+				   -----
+configure.ac,builtins/shobj-conf,m4/threadlib.m4
+	- midnightbsd: update auto-configuration to treat MidnightBSD like
+	  FreeBSD. From https://savannah.gnu.org/patch/?10006
+
+				   12/30
+				   -----
+examples/loadables/stat.c
+	- stattime: use strftime with a default format or the format supplied
+	  with the -F option to format the file time information
+	- stat_builtin: now takes a -F fmt option for a strftime format string;
+	  change to function calling sequences to pass the format down to
+	  stattime
+
+examples/loadables/Makefile.in
+	- stat: now built and installed by default
+
+				   12/31
+				   -----
+command.h
+	- SUBSHELL_IGNTRAP: new flag value
+
+jobs.c
+	- make_child: set SUBSHELL_IGNTRAP in subshell_environment in the
+	  child process, meaning that we should not execute trap handlers for
+	  trapped signals
+
+execute_cmd.c
+	- execute_in_subshell, execute_simple_command, execute_disk_command:
+	  make sure to unset SUBSHELL_IGNTRAP after a child process restores
+	  the original signal dispositions
+	- execute_simple_command: make sure to set SUBSHELL_IGNTRAP after
+	  make_child returns and we're setting subshell_environment directly
+
+subst.c
+	- command_substitute,process_substitute: unset SUBSHELL_IGNTRAP after
+	  the child process has reset the trapped signal dispositions
+
+trap.c
+	- trap_handler: if we get a signal for which we have set a trap, but
+	  SUBSHELL_IGNTRAP is set in subshell_environmnent, make sure we
+	  restore the original signal disposition and resend the signal to
+	  ourselves. Fixes issue reported by Nikolay Borisov <nborisov@suse.com>
+	  (or at least makes the race window much smaller)
+
+sig.c
+	- initialize_terminating_signal: set the original signal handler from
+	  the return value from sigaction; a minor optimization that saves a
+	  system call or two
+
+				 1/5/2021
+				 --------
+builtins/declare.def
+	- declare_internal: make some option combinations that don't make
+	  sense errors (e.g., -f and -a/-A/-i/-n)
+	- declare_internal: if we build a new variable name by expanding the
+	  value of a nameref variable, make sure to chop the `+' in a `+='
+	  off before going on
+
+				    1/7
+				    ---
+doc/{bash.1,bashref.texi}
+	- bind: add an example to the synopsis making it clear that you can
+	  use any readline command line as a non-option argument, as it says
+	  in the text. From a report from Dan Jacobson <jidanni@jidanni.org>
+
+				   1/12
+				   ----
+locale.c
+	- local_shiftstates -> locale_shiftsates in the non-multibyte code
+	  branch. Reported by Henry Bent <henry.r.bent@gmail.com>
+
+subst.c
+	- expand_compound_assignment_word: make sure to call dispose_words on
+	  the WORD_LIST * returned from expand_oneword after turning it back
+	  into a string. Fixes memory leak reported by Alexander Mescheryakov
+	  <alexander.s.m@gmail.com>
+
+				   1/13
+				   ----
+variables.c
+	- bind_variable_internal: when performing an assignment to a subscripted
+	  array variable that was the value of a nameref (used in the original
+	  assignment), don't call make_variable_value on the value, since that
+	  messes up +=. Just call assign_array_element and let that take care
+	  of calling make_variable_value appropriately. Fixes bug reported by
+	  Oguz <oguzismailuysal@gmail.com>
+
+				   1/14
+				   ----
+findcmd.c
+	- search_for_command: if `checkhash' is set, don't add non-executable
+	  files to the command hash table, since we will just remove them
+	  later
+
+lib/sh/winsize.c
+	- get_new_window_size: set *rp and *cp even if READLINE is not defined
+
+				   1/15
+				   ----
+lib/sh/winsize.c
+	- get_new_window_size: call rl_set_window_size only if we can determine
+	  we're using readline: an interactive shell without no-line-editing,
+	  or if we've already initialized readline, presumably in a non-
+	  interactive shell 
+
+support/Makefile.in
+	- man2html: add LDFLAGS_FOR_BUILD to the recipe. Report from
+	  Jeffrey Walton <noloader@gmail.com>
+
+				   1/17
+				   ----
+lib/readline/misc.c
+	- rl_operate_and_get_next: fix old K&R function declaration. Report
+	  from Tom Tromey <tom@tromey.com>
+
+lib/readline/readline.c
+	- _rl_internal_char_cleanup: move code that cleans up the active region
+	  and deactivates the mark inside this function so callback mode
+	  applications get the intended functionality. Report and fix from
+	  sparrowhawk996@gmail.com
+
+lib/readline/bind.c
+	- rl_parse_and_bind: when using the arithmetic comparison operators on
+	  the version, make sure to invert the tests so that we stop parsing
+	  if the test fails. Report and fix from Tom Tromey <tom@tromey.com>
+
+				   1/19
+				   ----
+Makefile.in
+	- pipesize.h: add dependency on ${BUILTINS_LIBRARY} to avoid parallel
+	  makes trying to create it twice. Report and fix from
+	  Richard Purdie <richard.purdie@linuxfoundation.org>
+
+				   1/21
+				   ----
+subst.c
+	- param_expand: if a nameref expands to array[@] or array[*], make sure
+	  to call chk_atstar so the right variables are set to split the
+	  result. Report from Oguz <oguzismailuysal@gmail.com>
+
+				   1/22
+				   ----
+builtins/declare.def
+	- Rewrote to reduce complexity. Still needs some work.
+
+lib/readline/*.h, lib/tilde/tilde.h
+	- PARAMS: remove, rely on compilers understanding function prototypes
+
+lib/readline/{undo.c,histlib.h}
+	 - _hs_replace_history_data: move extern declaration to histlib.h
+
+lib/readline/readline.c
+	- _rl_parse_colors: instead of an extern declaration for this, include
+	  "parse-colors.h" for it
+
+lib/readline/{histfile.c,histlib.h}
+	- _hs_append_history_line: move extern declaration to histlib.h
+
+lib/readline/history.h
+	- HS_HISTORY_VERSION: define to 0x0801 (current library version) if
+	  it's not already defined. We conditionally define it in case an
+	  application has (unwisely) chosen to use it, since the history
+	  library doesn't do anything with it yet
+
+lib/readine/{rlprivate.h,{search,misc,readline}.c}
+	- _rl_free_history_entry: add extern declaration to rlprivate.h, remove
+	  extern declaration from c source files. Use HS_HISTORY_VERSION as a
+	  sentinel that it's ok to use HIST_ENTRY in rlprivate.h
+
+lib/readline/{rlprivate.h,{isearch,search,undo}.c}
+	- _rl_saved_line_for_history: add extern declaration to rlprivate.h,
+	  remove extern declaration from c source files, using HS_HISTORY_VERSION
+	  in the same way
+
+				   1/24
+				   ----
+lib/readline/signals.c
+	- _rl_handle_signal: make sure that all sigprocmask calls are protected
+	  by HAVE_POSIX_SIGNALS. Report and fix from Tom Tromey <tom@tromey.com>
+
+				   1/26
+				   ----
+lib/readline/callback.c
+	- rl_callback_read_char: make sure rl_linefunc is non-NULL before
+	  calling through the pointer. The line function could have been
+	  removed by the application before readline processes any typeahead
+	  input. Bug reported by Matthias Klose <doko@debian.org>, pointer
+	  to root cause from Koichi Murase <myoga.murase@gmail.com>
+
+lib/glob/glob.c
+	- skipname,wskipname: put in some additional checks for `.' to ensure
+	  that we don't get false positives (or incomplete tests) that can 
+	  affect the results of extglob patterns. Reported by
+	  gregrwm <rhn-users@greatlakedata.com>
+
+				   1/27
+				   ----
+lib/glob/glob.c
+	- extglob_skipname,wextglob_skipname: fixed an off-by-one error (SE
+	  was being set to one character before the end of the pattern string,
+	  not the null character at the end of the pattern string like other
+	  callers of glob_patscan) that caused the last character of the last
+	  subpattern to be cut off when calling skipname
+	- extglob_skipname,wextglob_skipname: some cleanups so the code is
+	  closer to identical for the single-byte and wide character versions
+
+				    2/1
+				    ---
+execute_cmd.c
+	- execute_simple_command: in posix mode, if we have a variable
+	  assignment error while assigning into the temporary environment (e.g.,
+	  assigning to a readonly variable), a non-interactive shell running a
+	  special builtin exits; a non-interactive shell running anything else
+	  jumps back to the top level. A shell compiled with -DSTRICT_POSIX
+	  exits unconditionally.
+	- execute_simple_command: make sure posix mode sets $? to non-zero
+	  if a variable assignment error occurs preceding a non-special builtin
+
+subst.c
+	- do_assignment_statements: take the code from expand_word_list_internal
+	  that performs assignment statements, either standalone or preceding 
+	  simple command names, and factor it out into this function
+	- expand_word_list_internal: call do_assignment_statements where
+	  appropriate
+
+				    2/2
+				    ---
+lib/glob/glob.c
+	- dequote_pathname: fix function definition for non-multibyte systems.
+	  Report and fix from Marc Aurèle La France <tsi@tuyoix.net>
+
+Makefile.in,doc/Makefile.in
+	- for certain targets, remove files before creating them to deal with
+	  symlinked build trees.
+	  Report and fix from Marc Aurèle La France <tsi@tuyoix.net>
+
+examples/loadables/accept.c
+	- include limits.h before typemax.h
+	  Report and fix from Marc Aurèle La France <tsi@tuyoix.net>
+
+builtins/gen-helpfiles.c
+	- if USING_BASH_MALLOC is defined, make sure to undefine malloc as well
+	  as free. Fixes bug reported by George R Goffe <grgoffe@yahoo.com>
+
+builtins/Makefile.in
+	- install-help: now depends on $(HELPFILES_TARGET) so we make sure the
+	  separate helpfiles are created before we try to install them if we
+	  don't go through the `all' makefile target
+
+configure.ac
+	- HELPDIR: now ${datadir}/bash/helpfiles
+
+				    2/3
+				    ---
+parse.y
+	- parse_string_to_word_list: before expanding a compound assignment
+	  statement body, make sure to save any alias that's currently being
+	  expanded. Restore the alias after the compound assignment is parsed.
+	  Reported back in 11/2020 by Alex fxmbsw7 Ratchev <fxmbsw7@gmail.com>
+
+				    2/4
+				    ---
+lib/readline/histexpand.c
+	- history_expand_internal: when calling the history_inhibit_expansion
+	  function, make sure to call it using the string as we've expanded it
+	  to that point (RESULT), adding the expansion and next characters
+	  temporarily, since we make expansion decisions based on what we've
+	  accumulated, not what we started with. This makes things like
+	  echo abc!$!$ work, where before the second `!' inhibited expansion
+	  because bash_history_inhibit_expansion mistakenly took it as the
+	  second character in a `$!' word expansion. Fixes bug reported back
+	  in 10/2020 by Paul Fox <paul.d.fox@gmail.com>
+
+array.h
+	- array_pop: instead of calling array_dispose_element from this macro,
+	  just call array_shift with the AS_DISPOSE flag
+
+				    2/5
+				    ---
+bashhist.c
+	- shell_comment: move condition to return 0 if the delimiter stack is
+	  not empty or the shell is parsing a here document into the function
+	  itself, don't have the callers check so the check is in one place.
+	  Fixes bug reported by Oguz <oguzismailuysal@gmail.com>
+
+array.h,variables.c
+	- ARRAY_ELEMENT_REPLACE: convenience define for modifying an array
+	  element's value
+
+variables.c
+	- pop_args: a couple of code simplifications
+
+				    2/7
+				    ---
+lib/malloc/malloc.c
+	- pagesz: at least MALLOC_PAGESIZE_MIN (4096) bytes
+	- union mhead: now 16-byte aligned on all systems, 32-bit and 64-bit
+	  pointers
+	- binsizes: since the smallest allocation overhead is now 16 bytes,
+	  redo the buckets so binsizes[0] == 32; adjust the thresholds for
+	  split/coalesce/prepopulate/mmap (NBUCKETS = 28; STARTBUCK = 0).
+	  Sizes stay pretty much the same; indices change
+	- consistently use MALLOC_SIZE_T instead of long/unsigned int/int
+	- use MAGIC8_NUMBYTES as the length of the mh_magic8 buffer, in case
+	  it changes later for alignment
+	- internal_remap: new function, calls mremap to reallocate a chunk of
+	  memory allocated using mmap(); called from internal_realloc if the
+	  old size and new size are both bigger than the mmap threshold
+	- internal_realloc: call internal_remap if the old size and new size
+	  are both above the threshold where we use mmap for allocation
+
+				   2/10
+				   ----
+include/timer.h
+	- new file, declaration for a timer struct to be used by a set of
+	  functions to implement timers using SIGALRM or select/pselect
+
+lib/sh/timers.c
+	- new file, set of functions to manipulate timer objects and timeouts
+	  using SIGALRM or select/pselect. Inspired by a patch from
+	  Koichi Murase <myoga.murase@gmail.com>. Not used yet
+
+				   2/11
+				   ----
+builtins/read.def
+	- read_builtin: if there is a timeout set, block SIGCHLD around calls
+	  to zread and its siblings, or calls to readline for `read -e', so
+	  SIGCHLD (and the consequent waitpid) doesn't interrupt the read.
+	  Fixes bug reported by Koichi Murase <myoga.murase@gmail.com>, but
+	  there may be a different fix coming
+
+Makefile.in,builtins/Makefile.in
+	- fix up dependencies, especially on builtins.h and builtext.h
+
+
+				   2/12
+				   ----
+lib/readline/input.c
+	- rl_read_key: if we set rl_done == 1, set RL_STATE_DONE as well
+	  Reported by Koichi Murase <myoga.murase@gmail.com>
+
+lib/readline/isearch.c
+	- _rl_search_getchar: only call _rl_read_mbstring if rl_read_key returns
+	  >= 0, avoid some work
+
+lib/readline/vi_mode.c
+	- _rl_vi_callback_change_char,_rl_vi_change_char: don't overwrite the
+	  last replacement string if _rl_vi_callback_getchar returns -1.
+	  It will likely make no difference, since the next read will return
+	  an error or EOF, but being careful
+	- rl_vi_overstrike: if _rl_overwrite_char doesn't return 0, break out
+	  of the loop
+
+lib/readline/text.c
+	- _rl_overwrite_char: return 1 if _rl_read_mbstring returns < 0 so
+	  we don't try to insert garbage
+
+bashline.c
+	- posix_edit_macros: handle rl_read_key() returning <= 0
+
+				   2/15
+				   ----
+parse.y
+	- read_comsub: make sure to turn on the LEX_RESWDOK flag if we are in
+	  a case statement and read a `)', since we can get a valid `esac'.
+	  Fixes bug reported by Oguz <oguzismailuysal@gmail.com>
+	- read_comsub: if we're in a case statement, recognize `}' as a
+	  reserved word and set the LEX_RESWDOK flag for the next word, since
+	  we can get an esac (or another reserved word) after it
+
+				   2/16
+				   ----
+parse.y
+	- reserved_word_acceptable: add ARITH_CMD and COND_END to the list of
+	  tokens that can precede a reserved word, so you can use reserved
+	  words after ((...)) and [[...]].
+	  Reported by Koichi Murase <myoga.murase@gmail.com>

+	- array_variable_name: make sure we pass (FLAGS&1) to skipsubscript, so
+	  we don't inadvertently pass a value with bit 2 set, which would
+	  cause an off-by-one error in subscript parsing
+

+trap.c
+	- restore_traps: inverse of reset_signal_handlers. This understands
+	  how reset_signal_handlers changes the signal disposition while
+	  leaving the trap string in place, and knows how to restore flags
+	  and state based on that preserved trap string and whether or not
+	  the signal is "special" to the shell.
+
+builtins/exec.def
+	- exec_builtin: instead of using restore_original_signals to completely
+	  cancel the traps, call reset_signal_handlers so the trap strings are
+	  preserved. Then if the exec fails (and we're not exiting) we can
+	  look at the trap strings and see how to restore the trap state.
+	  This calls restore_traps after reinitializing the shell signal
+	  handlers, using the trap strings saved by reset_signal_handlers.
+	  Fixes issue with not exiting after a failed exec clearing the EXIT
+	  trap reported by Mark March <march@systempad.org>, using the
+	  approach suggested by Robert Elz <kre@munnari.OZ.AU>
+
+subst.c
+	- expand_declaration_argument: when parsing options that modify
+	  attributes that affect how the value is handled (i, c, u, etc.),
+	  make sure to create an option string and call make_internal_declare
+	  with options that start with a `+' so the attribute is off when
+	  the assignment is performed and changes how the value is expanded.

+lib/readline/complete.c
+	- rl_display_match_list: even if _rl_completion_prefix_display_length
+	  is set to a non-zero value, pass the common prefix length to
+	  fnprint if we've turned on colored completion prefixes; passes
+	  through to fnprint via print_filename
+	- fnprint: add the ellipsis if prefix_bytes exceeds the
+	  _rl_completion_prefix_display_length, add explicit check for
+	  prefix_bytes being longer since print_filename passes it through
+	  if colored-completion-prefix is set. This means that while
+	  completion-prefix-display-length still has precedence over
+	  colored-completion-prefix, it doesn't override it if both are set
+	  and the common prefix length is shorter than
+	  completion-prefix-display-length. From a report by

+arrayfunc.c

+	- unbind_array_element: assume the caller (unset_builtin) passes a

+	- reset_parser: set extended_glob from global_extglob if the parser
+	  state includes PST_CMDSUBST
+	- xparse_dolparen: set global_extglob but don't modify extended_glob,

+				 ---------
+
+[bash-5.1 released]
+
+				   12/7
+				   ----
+Makefile.in
+	- bashline.o: add dependency on ${DEFDIR}/builtext.h. Report from
+	  Fazal Majid <fazal@majid.org>
+
+				   12/11
+				   -----
+builtins/wait.def
+	- wait_builtin: don't assign the variable given with -p if there are no
+	  jobs to wait for. Report and fix from OÄuz <oguzismailuysal@gmail.com>
+
+arrayfunc.c
+	- kvpair_assignment_p: return non-zero if argument L appears to be a
+	  key-value pair associative array compound assignment
+	- expand_and_quote_kvpair_word: run a single word in a key-value pair
+	  associative array compound assignment through the appropriate
+	  expansions and single-quote the result
+
+arrayfunc.h
+	- kvpair_assignment_p, expand_and_quote_kvpair_word: extern declarations
+
+subst.c
+	- expand_oneword: detect whether VALUE appears to be a key-value
+	  pair compound assignment and call the appropriate function to expand
+	  each word in the resulting list. Fixes inconsistency reported by
+	  oguzismailuysal@gmail.com
+
+				   12/12
+				   -----
+subst.c
+	- command_substitute: don't reset pipeline_pgrp to shell_pgrp if we
+	  are already forked to run a command (SUBSHELL_FORK). Fixes SIGINT
+	  in command substitution in here-document in forked child issue
+	  reported by oguzismailuysal@gmail.com
+
+				   12/18
+				   -----
+execute_cmd.c
+	- execute_pipeline: execute the lastpipe code even if prev == 0. It
+	  can only be 0 here if stdin was closed when this function was
+	  executed
+	- execute_pipeline: if prev == 0, set lstdin to a sentinel (-1) that
+	  means to close fd 0 after executing the command, and call close(prev)
+	  before restoring stdin. restore_stdin now understands -1, and closes
+	  fd 0. Fixes issue reported by Tomas Janousek <tomi@nomi.cz>
+
+				   12/21
+				   -----
+doc/bashref.texi
+	- PROMPT_COMMANDS: clean up a couple of remaining instances of this
+	  name. Report from Eli Schwartz <eschwartz@archlinux.org>
+
+				   12/26
+				   -----
+subst.c
+	- command_substitute: make sure that the child process always has
+	  pipeline_pgrp == shell_pgrp: if pipeline_pgrp is non-zero when we
+	  get to the child, meaning that we're part of an already-forked
+	  child that is, for instance, running redirections, we need to reset
+	  shell_pgrp to it to preserve the invariant. Fixes bug with terminal
+	  being set to the incorrect pgrp reported by oguzismailuysal@gmail.com
+
+				   12/29
+				   -----
+configure.ac,builtins/shobj-conf,m4/threadlib.m4
+	- midnightbsd: update auto-configuration to treat MidnightBSD like
+	  FreeBSD. From https://savannah.gnu.org/patch/?10006
+
+				   12/30
+				   -----
+examples/loadables/stat.c
+	- stattime: use strftime with a default format or the format supplied
+	  with the -F option to format the file time information
+	- stat_builtin: now takes a -F fmt option for a strftime format string;
+	  change to function calling sequences to pass the format down to
+	  stattime
+
+examples/loadables/Makefile.in
+	- stat: now built and installed by default
+
+				   12/31
+				   -----
+command.h
+	- SUBSHELL_IGNTRAP: new flag value
+
+jobs.c
+	- make_child: set SUBSHELL_IGNTRAP in subshell_environment in the
+	  child process, meaning that we should not execute trap handlers for
+	  trapped signals
+
+execute_cmd.c
+	- execute_in_subshell, execute_simple_command, execute_disk_command:
+	  make sure to unset SUBSHELL_IGNTRAP after a child process restores
+	  the original signal dispositions
+	- execute_simple_command: make sure to set SUBSHELL_IGNTRAP after
+	  make_child returns and we're setting subshell_environment directly
+
+subst.c
+	- command_substitute,process_substitute: unset SUBSHELL_IGNTRAP after
+	  the child process has reset the trapped signal dispositions
+
+trap.c
+	- trap_handler: if we get a signal for which we have set a trap, but
+	  SUBSHELL_IGNTRAP is set in subshell_environmnent, make sure we
+	  restore the original signal disposition and resend the signal to
+	  ourselves. Fixes issue reported by Nikolay Borisov <nborisov@suse.com>
+	  (or at least makes the race window much smaller)
+
+sig.c
+	- initialize_terminating_signal: set the original signal handler from
+	  the return value from sigaction; a minor optimization that saves a
+	  system call or two
+
+				 1/5/2021
+				 --------
+builtins/declare.def
+	- declare_internal: make some option combinations that don't make
+	  sense errors (e.g., -f and -a/-A/-i/-n)
+	- declare_internal: if we build a new variable name by expanding the
+	  value of a nameref variable, make sure to chop the `+' in a `+='
+	  off before going on
+
+				    1/7
+				    ---
+doc/{bash.1,bashref.texi}
+	- bind: add an example to the synopsis making it clear that you can
+	  use any readline command line as a non-option argument, as it says
+	  in the text. From a report from Dan Jacobson <jidanni@jidanni.org>
+
+				   1/12
+				   ----
+locale.c
+	- local_shiftstates -> locale_shiftsates in the non-multibyte code
+	  branch. Reported by Henry Bent <henry.r.bent@gmail.com>
+
+subst.c
+	- expand_compound_assignment_word: make sure to call dispose_words on
+	  the WORD_LIST * returned from expand_oneword after turning it back
+	  into a string. Fixes memory leak reported by Alexander Mescheryakov
+	  <alexander.s.m@gmail.com>
+
+				   1/13
+				   ----
+variables.c
+	- bind_variable_internal: when performing an assignment to a subscripted
+	  array variable that was the value of a nameref (used in the original
+	  assignment), don't call make_variable_value on the value, since that
+	  messes up +=. Just call assign_array_element and let that take care
+	  of calling make_variable_value appropriately. Fixes bug reported by
+	  Oguz <oguzismailuysal@gmail.com>
+
+				   1/14
+				   ----
+findcmd.c
+	- search_for_command: if `checkhash' is set, don't add non-executable
+	  files to the command hash table, since we will just remove them
+	  later
+
+lib/sh/winsize.c
+	- get_new_window_size: set *rp and *cp even if READLINE is not defined
+
+				   1/15
+				   ----
+lib/sh/winsize.c
+	- get_new_window_size: call rl_set_window_size only if we can determine
+	  we're using readline: an interactive shell without no-line-editing,
+	  or if we've already initialized readline, presumably in a non-
+	  interactive shell 
+
+support/Makefile.in
+	- man2html: add LDFLAGS_FOR_BUILD to the recipe. Report from
+	  Jeffrey Walton <noloader@gmail.com>
+
+				   1/17
+				   ----
+lib/readline/misc.c
+	- rl_operate_and_get_next: fix old K&R function declaration. Report
+	  from Tom Tromey <tom@tromey.com>
+
+lib/readline/readline.c
+	- _rl_internal_char_cleanup: move code that cleans up the active region
+	  and deactivates the mark inside this function so callback mode
+	  applications get the intended functionality. Report and fix from
+	  sparrowhawk996@gmail.com
+
+lib/readline/bind.c
+	- rl_parse_and_bind: when using the arithmetic comparison operators on
+	  the version, make sure to invert the tests so that we stop parsing
+	  if the test fails. Report and fix from Tom Tromey <tom@tromey.com>
+
+				   1/19
+				   ----
+Makefile.in
+	- pipesize.h: add dependency on ${BUILTINS_LIBRARY} to avoid parallel
+	  makes trying to create it twice. Report and fix from
+	  Richard Purdie <richard.purdie@linuxfoundation.org>
+
+				   1/21

+
+builtins/exec.def
+	- exec_builtin: instead of using restore_original_signals to completely

+	  preserved. Then if the exec fails (and we're not exiting) we can
+	  look at the trap strings and see how to restore the trap state.
+	  This calls restore_traps after reinitializing the shell signal

+Basic Installation
+==================
+
+These are installation instructions for Bash.
+
+The simplest way to compile Bash is:
+
+  1. 'cd' to the directory containing the source code and type
+     './configure' to configure Bash for your system.  If you're using
+     'csh' on an old version of System V, you might need to type 'sh
+     ./configure' instead to prevent 'csh' from trying to execute
+     'configure' itself.
+
+     Running 'configure' takes some time.  While running, it prints
+     messages telling which features it is checking for.
+
+  2. Type 'make' to compile Bash and build the 'bashbug' bug reporting
+     script.
+
+  3. Optionally, type 'make tests' to run the Bash test suite.
+
+  4. Type 'make install' to install 'bash' and 'bashbug'.  This will
+     also install the manual pages and Info file, message translation
+     files, some supplemental documentation, a number of example
+     loadable builtin commands, and a set of header files for developing
+     loadable builtins.  You may need additional privileges to install
+     'bash' to your desired destination, so 'sudo make install' might be
+     required.  More information about controlling the locations where
+     'bash' and other files are installed is below (*note Installation
+     Names::).
+
+The 'configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a 'Makefile' in each directory of the package
+(the top directory, the 'builtins', 'doc', 'po', and 'support'
+directories, each directory under 'lib', and several others).  It also
+creates a 'config.h' file containing system-dependent definitions.
+Finally, it creates a shell script named 'config.status' that you can
+run in the future to recreate the current configuration, a file
+'config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file 'config.log' containing compiler output
+(useful mainly for debugging 'configure').  If at some point
+'config.cache' contains results you don't want to keep, you may remove
+or edit it.
+
+To find out more about the options and arguments that the 'configure'
+script understands, type
+
+     bash-4.2$ ./configure --help
+
+at the Bash prompt in your Bash source directory.
+
+If you want to build Bash in a directory separate from the source
+directory - to build for multiple architectures, for example - just use
+the full path to the configure script.  The following commands will
+build bash in a directory under '/usr/local/build' from the source code
+in '/usr/local/src/bash-4.4':
+
+     mkdir /usr/local/build/bash-4.4
+     cd /usr/local/build/bash-4.4
+     bash /usr/local/src/bash-4.4/configure
+     make
+
+See *note Compiling For Multiple Architectures:: for more information
+about building in a directory separate from the source.
+
+If you need to do unusual things to compile Bash, please try to figure
+out how 'configure' could check whether or not to do them, and mail
+diffs or instructions to <bash-maintainers@gnu.org> so they can be
+considered for the next release.
+
+The file 'configure.ac' is used to create 'configure' by a program
+called Autoconf.  You only need 'configure.ac' if you want to change it
+or regenerate 'configure' using a newer version of Autoconf.  If you do
+this, make sure you are using Autoconf version 2.69 or newer.
+
+You can remove the program binaries and object files from the source
+code directory by typing 'make clean'.  To also remove the files that
+'configure' created (so you can compile Bash for a different kind of
+computer), type 'make distclean'.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+'configure' script does not know about.  You can give 'configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+On systems that have the 'env' program, you can do it like this:
+
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+The configuration process uses GCC to build Bash if it is available.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile Bash for more than one kind of computer at the same
+time, by placing the object files for each architecture in their own
+directory.  To do this, you must use a version of 'make' that supports
+the 'VPATH' variable, such as GNU 'make'.  'cd' to the directory where
+you want the object files and executables to go and run the 'configure'
+script from the source directory (*note Basic Installation::).  You may
+need to supply the '--srcdir=PATH' argument to tell 'configure' where
+the source files are.  'configure' automatically checks for the source
+code in the directory that 'configure' is in and in '..'.
+
+If you have to use a 'make' that does not support the 'VPATH' variable,
+you can compile Bash for one architecture at a time in the source code
+directory.  After you have installed Bash for one architecture, use
+'make distclean' before reconfiguring for another architecture.
+
+Alternatively, if your system supports symbolic links, you can use the
+'support/mkclone' script to create a build tree which has symbolic links
+back to each file in the source directory.  Here's an example that
+creates a build directory in the current directory from a source
+directory '/usr/gnu/src/bash-2.0':
+
+     bash /usr/gnu/src/bash-2.0/support/mkclone -s /usr/gnu/src/bash-2.0 .
+
+The 'mkclone' script requires Bash, so you must have already built Bash
+for at least one architecture before you can create build directories
+for other architectures.
+
+Installation Names
+==================
+
+By default, 'make install' will install into '/usr/local/bin',
+'/usr/local/man', etc.; that is, the "installation prefix" defaults to
+'/usr/local'.  You can specify an installation prefix other than
+'/usr/local' by giving 'configure' the option '--prefix=PATH', or by
+specifying a value for the 'prefix' 'make' variable when running 'make
+install' (e.g., 'make install prefix=PATH').  The 'prefix' variable
+provides a default for 'exec_prefix' and other variables used when
+installing bash.
+
+You can specify separate installation prefixes for architecture-specific
+files and architecture-independent files.  If you give 'configure' the
+option '--exec-prefix=PATH', 'make install' will use PATH as the prefix
+for installing programs and libraries.  Documentation and other data
+files will still use the regular prefix.
+
+If you would like to change the installation locations for a single run,
+you can specify these variables as arguments to 'make': 'make install
+exec_prefix=/' will install 'bash' and 'bashbug' into '/bin' instead of
+the default '/usr/local/bin'.
+
+If you want to see the files bash will install and where it will install
+them without changing anything on your system, specify the variable
+'DESTDIR' as an argument to 'make'.  Its value should be the absolute
+directory path you'd like to use as the root of your sample installation
+tree.  For example,
+
+     mkdir /fs1/bash-install
+     make install DESTDIR=/fs1/bash-install
+
+will install 'bash' into '/fs1/bash-install/usr/local/bin/bash', the
+documentation into directories within
+'/fs1/bash-install/usr/local/share', the example loadable builtins into
+'/fs1/bash-install/usr/local/lib/bash', and so on.  You can use the
+usual 'exec_prefix' and 'prefix' variables to alter the directory paths
+beneath the value of 'DESTDIR'.
+
+The GNU Makefile standards provide a more complete description of these
+variables and their effects.
+
+Specifying the System Type
+==========================
+
+There may be some features 'configure' can not figure out automatically,
+but needs to determine by the type of host Bash will run on.  Usually
+'configure' can figure that out, but if it prints a message saying it
+can not guess the host type, give it the '--host=TYPE' option.  'TYPE'
+can either be a short name for the system type, such as 'sun4', or a
+canonical name with three fields: 'CPU-COMPANY-SYSTEM' (e.g.,
+'i386-unknown-freebsd4.2').
+
+See the file 'support/config.sub' for the possible values of each field.
+
+Sharing Defaults
+================
+
+If you want to set default values for 'configure' scripts to share, you
+can create a site shell script called 'config.site' that gives default
+values for variables like 'CC', 'cache_file', and 'prefix'.  'configure'
+looks for 'PREFIX/share/config.site' if it exists, then
+'PREFIX/etc/config.site' if it exists.  Or, you can set the
+'CONFIG_SITE' environment variable to the location of the site script.
+A warning: the Bash 'configure' looks for a site script, but not all
+'configure' scripts do.
+
+Operation Controls
+==================
+
+'configure' recognizes the following options to control how it operates.
+
+'--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     './config.cache'.  Set FILE to '/dev/null' to disable caching, for
+     debugging 'configure'.
+
+'--help'
+     Print a summary of the options to 'configure', and exit.
+
+'--quiet'
+'--silent'
+'-q'
+     Do not print messages saying which checks are being made.
+
+'--srcdir=DIR'
+     Look for the Bash source code in directory DIR.  Usually
+     'configure' can determine that directory automatically.
+
+'--version'
+     Print the version of Autoconf used to generate the 'configure'
+     script, and exit.
+
+'configure' also accepts some other, not widely used, boilerplate
+options.  'configure --help' prints the complete list.
+
+Optional Features
+=================
+
+The Bash 'configure' has a number of '--enable-FEATURE' options, where
+FEATURE indicates an optional part of Bash.  There are also several
+'--with-PACKAGE' options, where PACKAGE is something like 'bash-malloc'
+or 'purify'.  To turn off the default use of a package, use
+'--without-PACKAGE'.  To configure Bash without a feature that is
+enabled by default, use '--disable-FEATURE'.
+
+Here is a complete list of the '--enable-' and '--with-' options that
+the Bash 'configure' recognizes.
+
+'--with-afs'
+     Define if you are using the Andrew File System from Transarc.
+
+'--with-bash-malloc'
+     Use the Bash version of 'malloc' in the directory 'lib/malloc'.
+     This is not the same 'malloc' that appears in GNU libc, but an
+     older version originally derived from the 4.2 BSD 'malloc'.  This
+     'malloc' is very fast, but wastes some space on each allocation.
+     This option is enabled by default.  The 'NOTES' file contains a
+     list of systems for which this should be turned off, and
+     'configure' disables this option automatically for a number of
+     systems.
+
+'--with-curses'
+     Use the curses library instead of the termcap library.  This should
+     be supplied if your system has an inadequate or incomplete termcap
+     database.
+
+'--with-gnu-malloc'
+     A synonym for '--with-bash-malloc'.
+
+'--with-installed-readline[=PREFIX]'
+     Define this to make Bash link with a locally-installed version of
+     Readline rather than the version in 'lib/readline'.  This works
+     only with Readline 5.0 and later versions.  If PREFIX is 'yes' or
+     not supplied, 'configure' uses the values of the make variables
+     'includedir' and 'libdir', which are subdirectories of 'prefix' by
+     default, to find the installed version of Readline if it is not in
+     the standard system include and library directories.  If PREFIX is
+     'no', Bash links with the version in 'lib/readline'.  If PREFIX is
+     set to any other value, 'configure' treats it as a directory
+     pathname and looks for the installed version of Readline in
+     subdirectories of that directory (include files in PREFIX/'include'
+     and the library in PREFIX/'lib').
+
+'--with-libintl-prefix[=PREFIX]'
+     Define this to make Bash link with a locally-installed version of
+     the libintl library instead of the version in 'lib/intl'.
+
+'--with-libiconv-prefix[=PREFIX]'
+     Define this to make Bash look for libiconv in PREFIX instead of the
+     standard system locations.  There is no version included with Bash.
+
+'--enable-minimal-config'
+     This produces a shell with minimal features, close to the
+     historical Bourne shell.
+
+There are several '--enable-' options that alter how Bash is compiled,
+linked, and installed, rather than changing run-time features.
+
+'--enable-largefile'
+     Enable support for large files
+     (http://www.unix.org/version2/whatsnew/lfs20mar.html) if the
+     operating system requires special compiler options to build
+     programs which can access large files.  This is enabled by default,
+     if the operating system provides large file support.
+
+'--enable-profiling'
+     This builds a Bash binary that produces profiling information to be
+     processed by 'gprof' each time it is executed.
+
+'--enable-separate-helpfiles'
+     Use external files for the documentation displayed by the 'help'
+     builtin instead of storing the text internally.
+
+'--enable-static-link'
+     This causes Bash to be linked statically, if 'gcc' is being used.
+     This could be used to build a version to use as root's shell.
+
+The 'minimal-config' option can be used to disable all of the following
+options, but it is processed first, so individual options may be enabled
+using 'enable-FEATURE'.
+
+All of the following options except for 'alt-array-implementation',
+'disabled-builtins', 'direxpand-default', 'strict-posix-default', and
+'xpg-echo-default' are enabled by default, unless the operating system
+does not provide the necessary support.
+
+'--enable-alias'
+     Allow alias expansion and include the 'alias' and 'unalias'
+     builtins (*note Aliases::).
+
+'--enable-alt-array-implementation'
+     This builds bash using an alternate implementation of arrays (*note
+     Arrays::) that provides faster access at the expense of using more
+     memory (sometimes many times more, depending on how sparse an array
+     is).
+
+'--enable-arith-for-command'
+     Include support for the alternate form of the 'for' command that
+     behaves like the C language 'for' statement (*note Looping
+     Constructs::).
+
+'--enable-array-variables'
+     Include support for one-dimensional array shell variables (*note
+     Arrays::).
+
+'--enable-bang-history'
+     Include support for 'csh'-like history substitution (*note History
+     Interaction::).
+
+'--enable-brace-expansion'
+     Include 'csh'-like brace expansion ( 'b{a,b}c' ==> 'bac bbc' ).
+     See *note Brace Expansion::, for a complete description.
+
+'--enable-casemod-attributes'
+     Include support for case-modifying attributes in the 'declare'
+     builtin and assignment statements.  Variables with the 'uppercase'
+     attribute, for example, will have their values converted to
+     uppercase upon assignment.
+
+'--enable-casemod-expansion'
+     Include support for case-modifying word expansions.
+
+'--enable-command-timing'
+     Include support for recognizing 'time' as a reserved word and for
+     displaying timing statistics for the pipeline following 'time'
+     (*note Pipelines::).  This allows pipelines as well as shell
+     builtins and functions to be timed.
+
+'--enable-cond-command'
+     Include support for the '[[' conditional command.  (*note
+     Conditional Constructs::).
+
+'--enable-cond-regexp'
+     Include support for matching POSIX regular expressions using the
+     '=~' binary operator in the '[[' conditional command.  (*note
+     Conditional Constructs::).
+
+'--enable-coprocesses'
+     Include support for coprocesses and the 'coproc' reserved word
+     (*note Pipelines::).
+
+'--enable-debugger'
+     Include support for the bash debugger (distributed separately).
+
+'--enable-dev-fd-stat-broken'
+     If calling 'stat' on /dev/fd/N returns different results than
+     calling 'fstat' on file descriptor N, supply this option to enable
+     a workaround.  This has implications for conditional commands that
+     test file attributes.
+
+'--enable-direxpand-default'
+     Cause the 'direxpand' shell option (*note The Shopt Builtin::) to
+     be enabled by default when the shell starts.  It is normally
+     disabled by default.
+
+'--enable-directory-stack'
+     Include support for a 'csh'-like directory stack and the 'pushd',
+     'popd', and 'dirs' builtins (*note The Directory Stack::).
+
+'--enable-disabled-builtins'
+     Allow builtin commands to be invoked via 'builtin xxx' even after
+     'xxx' has been disabled using 'enable -n xxx'.  See *note Bash
+     Builtins::, for details of the 'builtin' and 'enable' builtin
+     commands.
+
+'--enable-dparen-arithmetic'
+     Include support for the '((...))' command (*note Conditional
+     Constructs::).
+
+'--enable-extended-glob'
+     Include support for the extended pattern matching features
+     described above under *note Pattern Matching::.
+
+'--enable-extended-glob-default'
+     Set the default value of the 'extglob' shell option described above
+     under *note The Shopt Builtin:: to be enabled.
+
+'--enable-function-import'
+     Include support for importing function definitions exported by
+     another instance of the shell from the environment.  This option is
+     enabled by default.
+
+'--enable-glob-asciirange-default'
+     Set the default value of the 'globasciiranges' shell option
+     described above under *note The Shopt Builtin:: to be enabled.
+     This controls the behavior of character ranges when used in pattern
+     matching bracket expressions.
+
+'--enable-help-builtin'
+     Include the 'help' builtin, which displays help on shell builtins
+     and variables (*note Bash Builtins::).
+
+'--enable-history'
+     Include command history and the 'fc' and 'history' builtin commands
+     (*note Bash History Facilities::).
+
+'--enable-job-control'
+     This enables the job control features (*note Job Control::), if the
+     operating system supports them.
+
+'--enable-multibyte'
+     This enables support for multibyte characters if the operating
+     system provides the necessary support.
+
+'--enable-net-redirections'
+     This enables the special handling of filenames of the form
+     '/dev/tcp/HOST/PORT' and '/dev/udp/HOST/PORT' when used in
+     redirections (*note Redirections::).
+
+'--enable-process-substitution'
+     This enables process substitution (*note Process Substitution::) if
+     the operating system provides the necessary support.
+
+'--enable-progcomp'
+     Enable the programmable completion facilities (*note Programmable
+     Completion::).  If Readline is not enabled, this option has no
+     effect.
+
+'--enable-prompt-string-decoding'
+     Turn on the interpretation of a number of backslash-escaped
+     characters in the '$PS0', '$PS1', '$PS2', and '$PS4' prompt
+     strings.  See *note Controlling the Prompt::, for a complete list
+     of prompt string escape sequences.
+
+'--enable-readline'
+     Include support for command-line editing and history with the Bash
+     version of the Readline library (*note Command Line Editing::).
+
+'--enable-restricted'
+     Include support for a "restricted shell".  If this is enabled,
+     Bash, when called as 'rbash', enters a restricted mode.  See *note
+     The Restricted Shell::, for a description of restricted mode.
+
+'--enable-select'
+     Include the 'select' compound command, which allows the generation
+     of simple menus (*note Conditional Constructs::).
+
+'--enable-single-help-strings'
+     Store the text displayed by the 'help' builtin as a single string
+     for each help topic.  This aids in translating the text to
+     different languages.  You may need to disable this if your compiler
+     cannot handle very long string literals.
+
+'--enable-strict-posix-default'
+     Make Bash POSIX-conformant by default (*note Bash POSIX Mode::).
+
+'--enable-translatable-strings'
+     Enable support for '$"STRING"' translatable strings (*note Locale
+     Translation::).
+
+'--enable-usg-echo-default'
+     A synonym for '--enable-xpg-echo-default'.
+
+'--enable-xpg-echo-default'
+     Make the 'echo' builtin expand backslash-escaped characters by
+     default, without requiring the '-e' option.  This sets the default
+     value of the 'xpg_echo' shell option to 'on', which makes the Bash
+     'echo' behave more like the version specified in the Single Unix
+     Specification, version 3.  *Note Bash Builtins::, for a description
+     of the escape sequences that 'echo' recognizes.
+
+The file 'config-top.h' contains C Preprocessor '#define' statements for
+options which are not settable from 'configure'.  Some of these are not
+meant to be changed; beware of the consequences if you do.  Read the
+comments associated with each definition for more information about its
+effect.

+This is a terse description of the new features added to bash-5.2 since
+the release of bash-5.1.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. The bash malloc returns memory that is aligned on 16-byte boundaries.
+
+b. There is a new internal timer framework used for read builtin timeouts.
+
+c. Rewrote the command substitution parsing code to call the parser recursively
+   and rebuild the command string from the parsed command. This allows better
+   syntax checking and catches errors much earlier. Along with this, if
+   command substitution parsing completes with here-documents remaining to be
+   read, the shell prints a warning message and reads the here-document bodies
+   from the current input stream.
+
+d. The `ulimit' builtin now treats an operand remaining after all of the options
+   and arguments are parsed as an argument to the last command specified by
+   an option. This is for POSIX compatibility.
+
+e. Here-document parsing now handles $'...' and $"..." quoting when reading the
+   here-document body.
+
+f. The `shell-expand-line' and `history-and-alias-expand-line' bindable readline
+   commands now understand $'...' and $"..." quoting.
+
+g. There is a new `spell-correct-word' bindable readline command to perform
+   spelling correction on the current word.
+
+h. The `unset' builtin now attempts to treat arguments as array subscripts
+   without parsing or expanding the subscript, even when `assoc_expand_once'
+   is not set.
+
+i. There is a default value for $BASH_LOADABLES_PATH in config-top.h.
+
+j. Associative array assignment and certain instances of referencing (e.g.,
+   `test -v' now allow `@' and `*' to be used as keys.
+
+k. Bash attempts to expand indexed array subscripts only once when executing
+   shell constructs and word expansions.
+
+l. The `unset' builtin allows a subscript of `@' or `*' to unset a key with
+   that value for associative arrays instead of unsetting the entire array
+   (which you can still do with `unset arrayname'). For indexed arrays, it
+   removes all elements of the array without unsetting it (like `A=()').
+
+m. Additional builtins (printf/test/read/wait) do a better job of not
+   parsing array subscripts if array_expand_once is set.
+
+n. New READLINE_ARGUMENT variable set to numeric argument for readline commands
+   defined using `bind -x'.
+
+o. The new `varredir_close' shell option causes bash to automatically close
+   file descriptors opened with {var}<fn and other styles of varassign
+   redirection unless they're arguments to the `exec' builtin.
+
+p. The `$0' special parameter is now set to the name of the script when running
+   any (non-interactive) startup files such as $BASH_ENV.
+
+q. The `enable' builtin tries to load a loadable builtin using the default
+   search path if `enable name' (without any options) attempts to enable a
+   non-existent builtin.
+
+r. The `printf' builtin has a new format specifier: %Q. This acts like %q but
+   applies any specified precision to the original unquoted argument, then
+   quotes and outputs the result.
+
+s. The new `noexpand_translations' option controls whether or not the translated
+   output of $"..." is single-quoted.
+
+t. There is a new parameter transformation operator: @k. This is like @K, but
+   expands the result to separate words after word splitting.
+
+u. There is an alternate array implementation, selectable at `configure' time,
+   that optimizes access speed over memory use (use the new configure
+    --enable-alt-array-implementation option).
+
+v. If an [N]<&WORD- or [N]>&WORD- redirection has WORD expand to the empty
+   string, treat the redirection as [N]<&- or [N]>&- and close file descriptor
+   N (default 0).
+
+w. Invalid parameter transformation operators are now invalid word expansions,
+   and so cause fatal errors in non-interactive shells.
+
+x. New shell option: patsub_replacement. When enabled, a `&' in the replacement
+   string of the pattern substitution expansion is replaced by the portion of
+   the string that matched the pattern. Backslash will escape the `&' and
+   insert a literal `&'.
+
+y. `command -p' no longer looks in the hash table for the specified command.
+
+z. The new `--enable-translatable-strings' option to `configure' allows $"..."
+   support to be compiled in or out.
+
+aa. The new `globskipdots' shell option forces pathname expansion never to
+    return `.' or `..' unless explicitly matched. It is enabled by default.
+
+bb. Array references using `@' and `*' that are the value of nameref variables
+    (declare -n ref='v[@]' ; echo $ref) no longer cause the shell to exit if
+    set -u is enabled and the array (v) is unset.
+
+cc. There is a new bindable readline command name:
+    `vi-edit-and-execute-command'.
+
+dd. In posix mode, the `printf' builtin checks for the `L' length modifier and
+    uses long double for floating point conversion specifiers if it's present,
+    double otherwise.
+
+ee. The `globbing' completion code now takes the `globstar' option into account.
+
+ff. `suspend -f' now forces the shell to suspend even if job control is not
+   currently enabled.
+
+gg. Since there is no `declare -' equivalent of `local -', make sure to use
+    `local -' in the output of `local -p'.
+
+2. New Features in Readline
+
+a. There is now an HS_HISTORY_VERSION containing the version number of the
+   history library for applications to use.
+
+b. History expansion better understands multiple history expansions that may
+   contain strings that would ordinarily inhibit history expansion (e.g.,
+   `abc!$!$').
+
+c. There is a new framework for readline timeouts, including new public
+   functions to set timeouts and query how much time is remaining before a
+   timeout hits, and a hook function that can trigger when readline times
+   out. There is a new state value to indicate a timeout.
+
+d. Automatically bind termcap key sequences for page-up and page-down to
+   history-search-backward and history-search-forward, respectively.
+
+e. There is a new `fetch-history' bindable command that retrieves the history
+   entry corresponding to its numeric argument. Negative arguments count back
+   from the end of the history.
+
+f. `vi-undo' is now a bindable command.
+
+g. There is a new option: `enable-active-region'. This separates control of
+   the active region and bracketed-paste. It has the same default value as
+   bracketed-paste, and enabling bracketed paste enables the active region.
+   Users can now turn off the active region while leaving bracketed paste
+   enabled.
+
+h. rl_completer_word_break_characters is now `const char *' like
+   rl_basic_word_break_characters.
+
+i. Readline looks in $LS_COLORS for a custom filename extension
+   (*.readline-colored-completion-prefix) and uses that as the default color
+   for the common prefix displayed when `colored-completion-prefix' is set.
+
+j. Two new bindable string variables: active-region-start-color and
+   active-region-end-color. The first sets the color used to display the
+   active region; the second turns it off. If set, these are used in place
+   of terminal standout mode.
+
+k. New readline state (RL_STATE_EOF) and application-visible variable
+   (rl_eof_found) to allow applications to detect when readline reads EOF
+   before calling the deprep-terminal hook.
+
+l. There is a new configuration option: --with-shared-termcap-library, which
+   forces linking the shared readline library with the shared termcap (or
+   curses/ncurses/termlib) library so applications don't have to do it.
+
+m. Readline now checks for changes to locale settings (LC_ALL/LC_CTYPE/LANG)
+   each time it is called, and modifies the appropriate locale-specific display
+   and key binding variables when the locale changes.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-5.1 since
+the release of bash-5.0.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. `bind -x' now supports different bindings for different editing modes and
+   keymaps.
+
+b. Bash attempts to optimize the number of times it forks when executing
+   commands in subshells and from `bash -c'.
+
+c. Here documents and here strings now use pipes for the expanded document if
+   it's smaller than the pipe buffer size, reverting to temporary files if it's
+   larger.
+
+d. There are new loadable builtins: mktemp, accept, mkfifo, csv, cut/lcut
+
+e. In posix mode, `trap -p' now displays signals whose disposition is SIG_DFL
+   and those that were SIG_IGN when the shell starts.
+
+f. The shell now expands the history number (e.g., in PS1) even if it is not
+   currently saving commands to the history list.
+
+g. `read -e' may now be used with arbitrary file descriptors (`read -u N').
+
+h. The `select' builtin now runs traps if its internal call to the read builtin
+   is interrupted by a signal.
+
+i. SRANDOM: a new variable that expands to a 32-bit random number that is not
+   produced by an LCRNG, and uses getrandom/getentropy, falling back to
+   /dev/urandom or arc4random if available. There is a fallback generator if
+   none of these are available.
+
+j. shell-transpose-words: a new bindable readline command that uses the same
+   definition of word as shell-forward-word, etc.
+
+k. The shell now adds default bindings for shell-forward-word,
+   shell-backward-word, shell-transpose-words, and shell-kill-word.
+
+l. Bash now allows ARGV0 appearing in the initial shell environment to set $0.
+
+m. If `unset' is executed without option arguments, bash tries to unset a shell
+   function if a name argument cannot be a shell variable name because it's not
+   an identifier.
+
+n. The `test -N' operator uses nanosecond timestamp granularity if it's
+   available.
+
+o. Bash posix mode now treats assignment statements preceding shell function
+   definitions the same as in its default mode, since POSIX has changed and
+   no longer requires those assignments to persist after the function returns
+   (POSIX interp 654).
+
+p. BASH_REMATCH is no longer readonly.
+
+q. wait: has a new -p VARNAME option, which stores the PID returned by `wait -n'
+   or `wait' without arguments.
+
+r. Sorting the results of pathname expansion now uses byte-by-byte comparisons
+   if two strings collate equally to impose a total order; the result of a
+   POSIX interpretation.
+
+s. Bash now allows SIGINT trap handlers to execute recursively.
+
+t. Bash now saves and restores state around setting and unsetting posix mode,
+   instead of having unsetting posix mode set a known state.
+
+u. Process substitution is now available in posix mode.
+
+v. READLINE_MARK: a new variable available while executing commands bound with
+   `bind -x', contains the value of the mark.
+
+w. Bash removes SIGCHLD from the set of blocked signals if it's blocked at shell
+   startup.
+
+x. `test -v N' can now test whether or not positional parameter N is set.
+
+y. `local' now honors the `-p' option to display all local variables at the
+    current context.
+
+z. The `@a' variable transformation now prints attributes for unset array
+   variables.
+
+aa. The `@A' variable transformation now prints a declare command that sets a
+    variable's attributes if the variable has attributes but is unset.
+
+bb. `declare' and `local' now have a -I option that inherits attributes and
+    value from a variable with the same name at a previous scope.
+
+cc. When run from a -c command, `jobs' now reports the status of completed jobs.
+
+dd. New `U', `u', and `L' parameter transformations to convert to uppercase,
+    convert first character to uppercase, and convert to lowercase,
+    respectively.
+
+ee. PROMPT_COMMAND: can now be an  array variable, each element of which can
+    contain a command to be executed like a string PROMPT_COMMAND variable.
+
+ff. `ulimit' has a -R option to report and set the RLIMIT_RTTIME resource.
+
+gg. Associative arrays may be assigned using a list of key-value pairs within
+    a compound assignment. Compound assignments where the words are not of
+    the form [key]=value are assumed to be key-value assignments. A missing or
+    empty key is an error; a missing value is treated as NULL. Assignments may
+    not mix the two forms.
+
+hh. New `K' parameter transformation to display associative arrays as key-
+    value pairs.
+
+ii. Writing history to syslog now handles messages longer than the syslog max
+    length by writing multiple messages with a sequence number.
+
+jj. SECONDS and RANDOM may now be assigned using arithmetic expressions, since
+    they are nominally integer variables. LINENO is not an integer variable.
+
+kk. Bash temporarily suppresses the verbose option when running the DEBUG trap
+    while running a command from the `fc' builtin.
+
+ll. `wait -n' now accepts a list of job specifications as arguments and will
+    wait for the first one in the list to change state.
+
+mm. The associative array implementation can now dynamically increase the
+    size of the hash table based on insertion patterns.
+
+nn. HISTFILE is now readonly in a restricted shell.
+
+oo. The bash malloc now returns memory that is 16-byte aligned on 64-bit
+    systems.
+
+pp. If the hash builtin is listing hashed filenames portably, don't print
+   anything if the table is empty.
+
+qq. GLOBIGNORE now ignores `.' and `..' as a terminal pathname component.
+
+rr. Bash attempts to optimize away forks in the last command in a function body
+    under appropriate circumstances.
+
+ss. The globbing code now uses fnmatch(3) to check collation elements (if
+    available) even in cases without multibyte characters.
+
+tt. The `fg' and `bg' builtins now return an error in a command substitution
+    when asked to restart a job inherited from the parent shell.
+
+uu. The shell now attempts to unlink all FIFOs on exit, whether a consuming
+    process has finished with them or not.
+
+vv. There is a new contributed loadable builtin: asort.
+
+2. New Features in Readline
+
+a. If a second consecutive completion attempt produces matches where the first
+   did not, treat it as a new completion attempt and insert a match as
+   appropriate.
+
+b. Bracketed paste mode works in more places: incremental search strings, vi
+   overstrike mode, character search, and reading numeric arguments.
+
+c. Readline automatically switches to horizontal scrolling if the terminal has
+   only one line.
+
+d. Unbinding all key sequences bound to a particular readline function now
+   descends into keymaps for multi-key sequences.
+
+e. rl-clear-display: new bindable command that clears the screen and, if
+   possible, the scrollback buffer (bound to emacs mode M-C-l by default).
+
+f. New active mark and face feature: when enabled, it will highlight the text
+   inserted by a bracketed paste (the `active region') and the text found by
+   incremental and non-incremental history searches. This is tied to bracketed
+   paste and can be disabled by turning off bracketed paste.
+
+g. Readline sets the mark in several additional commands.
+
+h. Bracketed paste mode is enabled by default.
+
+i. Readline tries to take advantage of the more regular structure of UTF-8
+   characters to identify the beginning and end of characters when moving
+   through the line buffer.
+
+j. The bindable operate-and-get-next command (and its default bindings) are
+   now part of readline instead of a bash-specific addition.
+
+k. The signal cleanup code now blocks SIGINT while processing after a SIGINT.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-5.0 since
+the release of bash-4.4.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1.  New Features in Bash
+
+a. The `wait' builtin can now wait for the last process substitution created.
+
+b. There is an EPOCHSECONDS variable, which expands to the time in seconds
+   since the Unix epoch.
+
+c. There is an EPOCHREALTIME variable, which expands to the time in seconds
+   since the Unix epoch with microsecond granularity.
+
+d. New loadable builtins: rm, stat, fdflags.
+
+e. BASH_ARGV0: a new variable that expands to $0 and sets $0 on assignment.
+
+f. When supplied a numeric argument, the shell-expand-line bindable readline
+   command does not perform quote removal and suppresses command and process
+   substitution.
+
+g. `history -d' understands negative arguments: negative arguments offset from
+   the end of the history list.
+
+h. The `name' argument to the `coproc' reserved word now undergoes word
+   expansion, so unique coprocs can be created in loops.
+
+i. A nameref name resolution loop in a function now resolves to a variable by
+   that name in the global scope.
+
+j. The `wait' builtin now has a `-f' option, which signifies to wait until the
+   specified job or process terminates, instead of waiting until it changes
+   state.
+
+k. There is a define in config-top.h that allows the shell to use a static
+   value for $PATH, overriding whatever is in the environment at startup, for
+   use by the restricted shell.
+
+l. Process substitution does not inherit the `v' option, like command
+   substitution.
+
+m. If a non-interactive shell with job control enabled detects that a foreground
+   job died due to SIGINT, it acts as if it received the SIGINT.
+
+n. The SIGCHLD trap is run once for each exiting child process even if job
+   control is not enabled when the shell is in Posix mode.
+
+o. A new shopt option: localvar_inherit; if set, a local variable inherits the
+   value of a variable with the same name at the nearest preceding scope.
+
+p. `bind -r' now checks whether a key sequence is bound before binding it to
+   NULL, to avoid creating keymaps for a multi-key sequence.
+
+q. A numeric argument to the line editing `operate-and-get-next' command
+   specifies which history entry to use.
+
+r. The positional parameters are now assigned before running the shell startup
+   files, so startup files can use $@.
+
+s. There is a compile-time option that forces the shell to disable the check
+   for an inherited OLDPWD being a directory.
+
+t. The `history' builtin can now delete ranges of history entries using
+   `-d start-end'.
+
+u. The `vi-edit-and-execute-command' bindable readline command now puts readline
+   back in vi insertion mode after executing commands from the edited file.
+
+v. The command completion code now matches aliases and shell function names
+   case-insensitively if the readline completion-ignore-case variable is set.
+
+w. There is a new `assoc_expand_once' shell option that attempts to expand
+   associative array subscripts only once.
+
+x. The shell only sets up BASH_ARGV and BASH_ARGC at startup if extended
+   debugging mode is active. The old behavior of unconditionally setting them
+   is available as part of the shell compatibility options.
+
+y. The `umask' builtin now allows modes and masks greater than octal 777.
+
+z. The `times' builtin now honors the current locale when printing a decimal
+   point.
+
+aa. There is a new (disabled by default, undocumented) shell option to enable
+    and disable sending history to syslog at runtime.
+
+bb. Bash no longer allows variable assignments preceding a special builtin that
+    changes variable attributes to propagate back to the calling environment
+    unless the compatibility level is 44 or lower.
+
+cc. You can set the default value for $HISTSIZE at build time in config-top.h.
+
+dd. The `complete' builtin now accepts a -I option that applies the completion
+    to the initial word on the line.
+
+ee.  The internal bash malloc now uses mmap (if available) to satisfy requests
+    greater than 128K bytes, so free can use mfree to return the pages to the
+    kernel.
+
+ff. The shell doesn't automatically set BASH_ARGC and BASH_ARGV at startup
+    unless it's in debugging mode, as the documentation has always said, but
+    will dynamically create them if a script references them at the top level
+    without having enabled debugging mode.
+
+gg. The localvar_inherit option will not attempt to inherit a value from a
+    variable of an incompatible type (indexed vs. associative arrays, for
+    example).
+
+hh. The `globasciiranges' option is now enabled by default; it can be set to
+    off by default at configuration time.
+
+ii. Associative and indexed arrays now allow subscripts consisting solely of
+    whitespace.
+
+jj. `checkwinsize' is now enabled by default.
+
+kk. The `localvar_unset' shopt option is now visible and documented.
+
+ll. The `progcomp_alias' shopt option is now visible and documented.
+
+mm. The signal name processing code now understands `SIGRTMIN+n' all the way
+    up to SIGRTMAX.
+
+nn. There is a new `seq' loadable builtin.
+
+oo. Trap execution now honors the (internal) max invocations of `eval', since
+    traps are supposed to be executed as if using `eval'.
+
+pp. The $_ variable doesn't change when the shell executes a command that forks.
+
+qq. The `kill' builtin now supports -sSIGNAME and -nSIGNUM, even though
+    conforming applications aren't supposed to use them.
+
+rr. POSIX mode now enables the `shift_verbose' option.
+
+2.  New Features in Readline
+
+a. Non-incremental vi-mode search (`N', `n') can search for a shell pattern, as
+   Posix specifies (uses fnmatch(3) if available).
+
+b. There are new `next-screen-line' and `previous-screen-line' bindable
+   commands, which move the cursor to the same column in the next, or previous,
+   physical line, respectively.
+
+c. There are default key bindings for control-arrow-key key combinations.
+
+d. A negative argument (-N) to `quoted-insert' means to insert the next N
+   characters using quoted-insert.
+
+e. New public function: rl_check_signals(), which allows applications to
+   respond to signals that readline catches while waiting for input using
+   a custom read function.
+
+f. There is new support for conditionally testing the readline version in an
+   inputrc file, with a full set of arithmetic comparison operators available.
+
+g. There is a simple variable comparison facility available for use within an
+   inputrc file. Allowable operators are equality and inequality; string
+   variables may be compared to a value; boolean variables must be compared to
+   either `on' or `off'; variable names are separated from the operator by
+   whitespace.
+
+h. The history expansion library now understands command and process
+   substitution and extended globbing and allows them to appear anywhere in a
+   word.
+
+i. The history library has a new variable that allows applications to set the
+   initial quoting state, so quoting state can be inherited from a previous
+   line.
+
+j. Readline now allows application-defined keymap names; there is a new public
+   function, rl_set_keymap_name(), to do that.
+
+k. The "Insert" keypad key, if available, now puts readline into overwrite
+   mode.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-4.4 since
+the release of bash-4.3.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1.  New Features in Bash
+
+a.  There is now a settable configuration #define that will cause the shell
+    to exit if the shell is running setuid without the -p option and setuid
+    to the real uid fails.
+
+b.  Command and process substitutions now turn off the `-v' option when
+    executing, as other shells seem to do.
+
+c.  The default value for the `checkhash' shell option may now be set at
+    compile time with a #define.
+
+d.  The `mapfile' builtin now has a -d option to use an arbitrary character
+    as the record delimiter, and a -t option  to strip the delimiter as
+    supplied with -d.
+
+e.  The maximum number of nested recursive calls to `eval' is now settable in
+    config-top.h; the default is no limit.
+
+f.  The `-p' option to declare and similar builtins will display attributes for
+    named variables even when those variables have not been assigned values
+    (which are technically unset).
+
+g.  The maximum number of nested recursive calls to `source' is now settable
+    in config-top.h; the default is no limit.
+
+h.  All builtin commands recognize the `--help' option and print a usage
+    summary.
+
+i.  Bash does not allow function names containing `/' and `=' to be exported.
+
+j.  The `ulimit' builtin has new -k (kqueues) and -P (pseudoterminals) options.
+
+k.  The shell now allows `time ; othercommand' to time null commands.
+
+l.  There is a new `--enable-function-import' configuration option to allow
+    importing shell functions from the environment; import is enabled by
+    default.
+
+m.  `printf -v var ""' will now set `var' to the empty string, as if `var=""'
+    had been executed.
+
+n.  GLOBIGNORE, the pattern substitution word expansion, and programmable
+    completion match filtering now honor the value of the `nocasematch' option.
+
+o.  There is a new ${parameter@spec} family of operators to transform the
+    value of `parameter'.
+
+p.  Bash no longer attempts to perform compound assignment if a variable on the
+    rhs of an assignment statement argument to `declare' has the form of a
+    compound assignment (e.g., w='(word)' ; declare foo=$w); compound
+    assignments are accepted if the variable was already declared as an array,
+    but with a warning.
+
+q.  The declare builtin no longer displays array variables using the compound
+    assignment syntax with quotes; that will generate warnings when re-used as
+    input, and isn't necessary.
+
+r.  Executing the rhs of && and || will no longer cause the shell to fork if
+    it's not necessary.
+
+s.  The `local' builtin takes a new argument: `-', which will cause it to save
+    and the single-letter shell options and restore their previous values at
+    function return.
+
+t.  `complete' and `compgen' have a new `-o nosort' option, which forces
+    readline to not sort the completion matches.
+
+u.  Bash now allows waiting for the most recent process substitution, since it
+    appears as $!.
+
+v.  The `unset' builtin now unsets a scalar variable if it is subscripted with
+    a `0', analogous to the ${var[0]} expansion.
+
+w.  `set -i' is no longer valid, as in other shells.
+
+x.  BASH_SUBSHELL is now updated for process substitution and group commands
+    in pipelines, and is available with the same value when running any exit
+    trap.
+
+y.  Bash now checks $INSIDE_EMACS as well as $EMACS when deciding whether or
+    not bash is being run in a GNU Emacs shell window.
+
+z.  Bash now treats SIGINT received when running a non-builtin command in a
+    loop the way it has traditionally treated running a builtin command:
+    running any trap handler and breaking out of the loop.
+
+aa. New variable: EXECIGNORE; a colon-separate list of patterns that will
+    cause matching filenames to be ignored when searching for commands.
+
+bb. Aliases whose value ends in a shell metacharacter now expand in a way to
+    allow them to be `pasted' to the next token, which can potentially change
+    the meaning of a command (e.g., turning `&' into `&&').
+
+cc. `make install' now installs the example loadable builtins and a set of
+    bash headers to use when developing new loadable builtins.
+
+dd. `enable -f' now attempts to call functions named BUILTIN_builtin_load when
+    loading BUILTIN, and BUILTIN_builtin_unload when deleting it.  This allows
+    loadable builtins to run initialization and cleanup code.
+
+ee. There is a new BASH_LOADABLES_PATH variable containing a list of directories
+    where the `enable -f' command looks for shared objects containing loadable
+    builtins.
+
+ff. The `complete_fullquote' option to `shopt' changes filename completion to
+    quote all shell metacharacters in filenames and directory names.
+
+gg. The `kill' builtin now has a `-L' option, equivalent to `-l', for
+    compatibility with Linux standalone versions of kill.
+
+hh. BASH_COMPAT and FUNCNEST can be inherited and set from the shell's initial
+    environment.
+
+ii. inherit_errexit: a new `shopt' option that, when set, causes command
+    substitutions to inherit the -e option.  By default, those subshells disable
+    -e.  It's enabled as part of turning on posix mode.
+
+jj. New prompt string: PS0.  Expanded and displayed by interactive shells after
+    reading a complete command but before executing it.
+
+kk. Interactive shells now behave as if SIGTSTP/SIGTTIN/SIGTTOU are set to
+    SIG_DFL when the shell is started, so they are set to SIG_DFL in child
+    processes.
+
+ll. Posix-mode shells now allow double quotes to quote the history expansion
+    character.
+
+mm. OLDPWD can be inherited from the environment if it names a directory.
+
+nn. Shells running as root no longer inherit PS4 from the environment, closing
+    a security hole involving PS4 expansion performing command substitution.
+
+oo. If executing an implicit `cd' when the `autocd' option is set, bash will
+    now invoke a function named `cd' if one exists before executing the `cd'
+    builtin.
+
+pp. Value conversions (arithmetic expansions, case modification, etc.) now
+    happen when assigning elements of an array using compound assignment.
+
+qq. There is a new option settable in config-top.h that makes multiple
+    directory arguments to `cd' a fatal error.
+
+rr. Bash now uses mktemp() when creating internal temporary files; it produces
+    a warning at build time on many Linux systems.
+
+2.  New Features in Readline
+
+a.  The history truncation code now uses the same error recovery mechanism as
+    the history writing code, and restores the old version of the history file
+    on error.  The error recovery mechanism handles symlinked history files.
+
+b.  There is a new bindable variable, `enable-bracketed-paste', which enables
+    support for a terminal's bracketed paste mode.
+
+c.  The editing mode indicators can now be strings and are user-settable
+    (new `emacs-mode-string', `vi-cmd-mode-string' and `vi-ins-mode-string'
+    variables).  Mode strings can contain invisible character sequences.
+    Setting mode strings to null strings restores the defaults.
+
+d.  Prompt expansion adds the mode string to the last line of a multi-line
+    prompt (one with embedded newlines).
+
+e.  There is a new bindable variable, `colored-completion-prefix', which, if
+    set, causes the common prefix of a set of possible completions to be
+    displayed in color.
+
+f.  There is a new bindable command `vi-yank-pop', a vi-mode version of emacs-
+    mode yank-pop.
+
+g.  The redisplay code underwent several efficiency improvements for multibyte
+    locales.
+
+h.  The insert-char function attempts to batch-insert all pending typeahead
+    that maps to self-insert, as long as it is coming from the terminal.
+
+i.  rl_callback_sigcleanup: a new application function that can clean up and
+    unset any state set by readline's callback mode.  Intended to be used
+    after a signal.
+
+j.  If an incremental search string has its last character removed with DEL, the
+    resulting empty search string no longer matches the previous line.
+
+k.  If readline reads a history file that begins with `#' (or the value of
+    the history comment character) and has enabled history timestamps, the
+    history entries are assumed to be delimited by timestamps.  This allows
+    multi-line history entries.
+
+l.  Readline now throws an error if it parses a key binding without a
+    terminating `:' or whitespace.
+
+m.  The default binding for ^W in vi mode now uses word boundaries specified
+    by Posix (vi-unix-word-rubout is bindable command name).
+
+n.  rl_clear_visible_line: new application-callable function; clears all
+    screen lines occupied by the current visible readline line.
+
+o.  rl_tty_set_echoing: application-callable function that controls whether
+    or not readline thinks it is echoing terminal output.
+
+p.  Handle >| and strings of digits preceding and following redirection
+    specifications as single tokens when tokenizing the line for history
+    expansion.
+
+q.  Fixed a bug with displaying completions when the prefix display length
+    is greater than the length of the completions to be displayed.
+
+r.  The :p history modifier now applies to the entire line, so any expansion
+    specifying :p causes the line to be printed instead of expanded.
+
+s.  New application-callable function: rl_pending_signal(): returns the signal
+    number of any signal readline has caught but not yet handled.
+
+t.  New application-settable variable: rl_persistent_signal_handlers: if set
+    to a non-zero value, readline will enable the readline-6.2 signal handler
+    behavior in callback mode: handlers are installed when
+    rl_callback_handler_install is called and removed removed when a complete
+    line has been read.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-4.3 since
+the release of bash-4.2.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1.  New Features in Bash
+
+a.  The `helptopic' completion action now maps to all the help topics, not just
+    the shell builtins.
+
+b.  The `help' builtin no longer does prefix substring matching first, so
+    `help read' does not match `readonly', but will do it if exact string
+    matching fails.
+
+c.  The shell can be compiled to not display a message about processes that
+    terminate due to SIGTERM.
+
+d.  Non-interactive shells now react to the setting of checkwinsize and set
+    LINES and COLUMNS after a foreground job exits.
+
+e.  There is a new shell option, `globasciiranges', which, when set to on,
+    forces globbing range comparisons to use character ordering as if they
+    were run in the C locale.
+
+f.  There is a new shell option, `direxpand', which makes filename completion
+    expand variables in directory names in the way bash-4.1 did.
+
+g.  In Posix mode, the `command' builtin does not change whether or not a
+    builtin it shadows is treated as an assignment builtin.
+
+h.  The `return' and `exit' builtins accept negative exit status arguments.
+
+i.  The word completion code checks whether or not a filename containing a
+    shell variable expands to a directory name and appends `/' to the word
+    as appropriate.  The same code expands shell variables in command names
+    when performing command completion.
+
+j.  In Posix mode, it is now an error to attempt to define a shell function
+    with the same name as a Posix special builtin.
+
+k.  When compiled for strict Posix conformance, history expansion is disabled
+    by default.
+
+l.  The history expansion character (!) does not cause history expansion when
+    followed by the closing quote in a double-quoted string.
+
+m.  `complete' and its siblings compgen/compopt now takes a new `-o noquote'
+    option to inhibit quoting of the completions.
+
+n.  Setting HISTSIZE to a value less than zero causes the history list to be
+    unlimited (setting it 0 zero disables the history list).
+
+o.  Setting HISTFILESIZE to a value less than zero causes the history file size
+    to be unlimited (setting it to 0 causes the history file to be truncated
+    to zero size).
+
+p.  The `read' builtin now skips NUL bytes in the input.
+
+q.  There is a new `bind -X' option to print all key sequences bound to Unix
+    commands.
+
+r.  When in Posix mode, `read' is interruptible by a trapped signal.  After
+    running the trap handler, read returns 128+signal and throws away any
+    partially-read input.
+
+s.  The command completion code skips whitespace and assignment statements
+    before looking for the command name word to be completed.
+
+t.  The build process has a new mechanism for constructing separate help files
+    that better reflects the current set of compilation options.
+
+u.  The -nt and -ot options to test now work with files with nanosecond
+    timestamp resolution.
+
+v.  The shell saves the command history in any shell for which history is
+    enabled and HISTFILE is set, not just interactive shells.
+
+w.  The shell has `nameref' variables and new -n(/+n) options to declare and
+    unset to use them, and a `test -R' option to test for them.
+
+x.  The shell now allows assigning, referencing, and unsetting elements of
+    indexed arrays using negative subscripts (a[-1]=2, echo ${a[-1]}) which
+    count back from the last element of the array.
+
+y.  The {x}<word redirection feature now allows words like {array[ind]} and
+    can use variables with special meanings to the shell (e.g., BASH_XTRACEFD).
+
+z.  There is a new CHILD_MAX special shell variable; its value controls the
+    number of exited child statues the shell remembers.
+
+aa. There is a new configuration option (--enable-direxpand-default) that
+    causes the `direxpand' shell option to be enabled by default.
+
+bb. Bash does not do anything special to ensure that the file descriptor
+    assigned to X in {x}<foo remains open after the block containing it
+    completes.
+
+cc. The `wait' builtin has a new `-n' option to wait for the next child to
+    change status.
+
+dd. The `printf' %(...)T format specifier now uses the current time if no
+    argument is supplied.
+
+ee. There is a new variable, BASH_COMPAT, that controls the current shell
+    compatibility level.
+
+ff. The `popd' builtin now treats additional arguments as errors.
+
+gg. The brace expansion code now treats a failed sequence expansion as a
+    simple string and will continue to expand brace terms in the remainder
+    of the word.
+
+hh. Shells started to run process substitutions now run any trap set on EXIT.
+
+ii. The fc builtin now interprets -0 as the current command line.
+
+jj. Completing directory names containing shell variables now adds a trailing
+    slash if the expanded result is a directory.
+
+kk. `cd' has a new `-@' option to browse a file's extended attributes on
+    systems that support O_XATTR.
+
+ll. The test/[/[[ `-v variable' binary operator now understands array
+    references.
+
+2.  New Features in Readline
+
+a.  Readline is now more responsive to SIGHUP and other fatal signals when
+    reading input from the terminal or performing word completion but no
+    longer attempts to run any not-allowable functions from a signal handler
+    context.
+
+b.  There are new bindable commands to search the history for the string of
+    characters between the beginning of the line and the point
+    (history-substring-search-forward, history-substring-search-backward)
+
+c.  Readline allows quoted strings as the values of variables when setting
+    them with `set'.  As a side effect, trailing spaces and tabs are ignored
+    when setting a string variable's value.
+
+d.  The history library creates a backup of the history file when writing it
+    and restores the backup on a write error.
+
+e.  New application-settable variable: rl_filename_stat_hook: a function called
+    with a filename before using it in a call to stat(2).  Bash uses it to
+    expand shell variables so things like $HOME/Downloads have a slash
+    appended.
+
+f.  New bindable function `print-last-kbd-macro', prints the most-recently-
+    defined keyboard macro in a reusable format.
+
+g.  New user-settable variable `colored-stats', enables use of colored text
+    to denote file types when displaying possible completions (colored analog
+    of visible-stats).
+
+h.  New user-settable variable `keyseq-timout', acts as an inter-character
+    timeout when reading input or incremental search strings.
+
+i.  New application-callable function: rl_clear_history. Clears the history list
+    and frees all readline-associated private data.
+
+j.  New user-settable variable, show-mode-in-prompt, adds a characters to the
+    beginning of the prompt indicating the current editing mode.
+
+k.  New application-settable variable: rl_input_available_hook; function to be
+    called when readline detects there is data available on its input file
+    descriptor.
+
+l.  Readline calls an application-set event hook (rl_event_hook) after it gets
+    a signal while reading input (read returns -1/EINTR but readline does not
+    handle the signal immediately) to allow the application to handle or
+    otherwise note it.
+
+m.  If the user-settable variable `history-size' is set to a value less than
+    0, the history list size is unlimited.
+
+n.  New application-settable variable: rl_signal_event_hook; function that is
+    called when readline is reading terminal input and read(2) is interrupted
+    by a signal.  Currently not called for SIGHUP or SIGTERM.
+
+o.  rl_change_environment: new application-settable variable that controls
+    whether or not Readline modifies the environment (currently readline
+    modifies only LINES and COLUMNS).
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-4.2 since
+the release of bash-4.1.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1.  New Features in Bash
+
+a.  `exec -a foo' now sets $0 to `foo' in an executable shell script without a
+    leading #!.
+
+b.  Subshells begun to execute command substitutions or run shell functions or
+    builtins in subshells do not reset trap strings until a new trap is
+    specified.  This allows $(trap) to display the caller's traps and the
+    trap strings to persist until a new trap is set.
+
+c.  `trap -p' will now show signals ignored at shell startup, though their
+    disposition still cannot be modified.
+
+d.  $'...', echo, and printf understand \uXXXX and \UXXXXXXXX escape sequences.
+
+e.  declare/typeset has a new `-g' option, which creates variables in the
+    global scope even when run in a shell function.
+
+f.  test/[/[[ have a new -v variable unary operator, which returns success if
+    `variable' has been set.
+
+g.  Posix parsing changes to allow `! time command' and multiple consecutive
+    instances of `!' (which toggle) and `time' (which have no cumulative
+    effect).
+
+h.  Posix change to allow `time' as a command by itself to print the elapsed
+    user, system, and real times for the shell and its children.
+
+j.  $((...)) is always parsed as an arithmetic expansion first, instead of as
+    a potential nested command substitution, as Posix requires.
+
+k.  A new FUNCNEST variable to allow the user to control the maximum shell
+    function nesting (recursive execution) level.
+
+l.  The mapfile builtin now supplies a third argument to the callback command:
+    the line about to be assigned to the supplied array index.
+
+m.  The printf builtin has a new %(fmt)T specifier, which allows time values
+    to use strftime-like formatting.
+
+n.  There is a new `compat41' shell option.
+
+o.  The cd builtin has a new Posix-mandated `-e' option.
+
+p.  Negative subscripts to indexed arrays, previously errors, now are treated
+    as offsets from the maximum assigned index + 1.
+
+q.  Negative length specifications in the ${var:offset:length} expansion,
+    previously errors, are now treated as offsets from the end of the variable.
+
+r.  Parsing change to allow `time -p --'.
+
+s.  Posix-mode parsing change to not recognize `time' as a keyword if the
+    following token begins with a `-'.  This means no more Posix-mode
+    `time -p'.  Posix interpretation 267.
+
+t.  There is a new `lastpipe' shell option that runs the last command of a
+    pipeline in the current shell context.  The lastpipe option has no
+    effect if job control is enabled.
+
+u.  History expansion no longer expands the `$!' variable expansion.
+
+v.  Posix mode shells no longer exit if a variable assignment error occurs
+    with an assignment preceding a command that is not a special builtin.
+
+w.  Non-interactive mode shells exit if -u is enabled and an attempt is made
+    to use an unset variable with the % or # expansions, the `//', `^', or
+    `,' expansions, or the parameter length expansion.
+
+x.  Posix-mode shells use the argument passed to `.' as-is if a $PATH search
+    fails, effectively searching the current directory.  Posix-2008 change.
+
+2.  New Features in Readline
+
+a.  The history library does not try to write the history filename in the
+    current directory if $HOME is unset.  This closes a potential security
+    problem if the application does not specify a history filename.
+
+b.  New bindable variable `completion-display-width' to set the number of
+    columns used when displaying completions.
+
+c.  New bindable variable `completion-case-map' to cause case-insensitive
+    completion to treat `-' and `_' as identical.
+
+d.  There are new bindable vi-mode command names to avoid readline's case-
+    insensitive matching not allowing them to be bound separately.
+
+e.  New bindable variable `menu-complete-display-prefix' causes the menu
+    completion code to display the common prefix of the possible completions
+    before cycling through the list, instead of after.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-4.1 since
+the release of bash-4.0.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1.  New Features in Bash
+
+a.  Here-documents within $(...) command substitutions may once more be
+    delimited by the closing right paren, instead of requiring a newline.
+
+b.  Bash's file status checks (executable, readable, etc.) now take file
+    system ACLs into account on file systems that support them.
+
+c.  Bash now passes environment variables with names that are not valid
+    shell variable names through into the environment passed to child
+    processes.
+
+d.  The `execute-unix-command' readline function now attempts to clear and
+    reuse the current line rather than move to a new one after the command
+    executes.
+
+e.  `printf -v' can now assign values to array indices.
+
+f.  New `complete -E' and `compopt -E' options that work on the "empty"
+    completion: completion attempted on an empty command line.
+
+g.  New complete/compgen/compopt -D option to define a `default' completion:
+    a completion to be invoked on command for which no completion has been
+    defined.  If this function returns 124, programmable completion is
+    attempted again, allowing a user to dynamically build a set of completions
+    as completion is attempted by having the default completion function
+    install individual completion functions each time it is invoked.
+
+h.  When displaying associative arrays, subscripts are now quoted.
+
+i.  Changes to dabbrev-expand to make it more `emacs-like': no space appended
+    after matches, completions are not sorted, and most recent history entries
+    are presented first.
+
+j.  The [[ and (( commands are now subject to the setting of `set -e' and the
+    ERR trap.
+
+k.  The source/. builtin now removes NUL bytes from the file before attempting
+    to parse commands.
+
+l.  There is a new configuration option (in config-top.h) that forces bash to
+    forward all history entries to syslog.
+
+m.  A new variable $BASHOPTS to export shell options settable using `shopt' to
+    child processes.
+
+n.  There is a new configure option that forces the extglob option to be
+    enabled by default.
+
+o.  New variable $BASH_XTRACEFD; when set to an integer bash will write xtrace
+    output to that file descriptor.
+
+p.  If the optional left-hand-side of a redirection is of the form {var}, the
+    shell assigns the file descriptor used to $var or uses $var as the file
+    descriptor to move or close, depending on the redirection operator.
+
+q.  The < and > operators to the [[ conditional command now do string
+    comparison according to the current locale if the compatibility level
+    is greater than 40.
+
+r.  Programmable completion now uses the completion for `b' instead of `a'
+    when completion is attempted on a line like: a $(b c.
+
+s.  Force extglob on temporarily when parsing the pattern argument to
+    the == and != operators to the [[ command, for compatibility.
+
+t.  Changed the behavior of interrupting the wait builtin when a SIGCHLD is
+    received and a trap on SIGCHLD is set to be Posix-mode only.
+
+u.  The read builtin has a new `-N nchars' option, which reads exactly NCHARS
+    characters, ignoring delimiters like newline.
+
+v.  The mapfile/readarray builtin no longer stores the commands it invokes via
+    callbacks in the history list.
+
+w.  There is a new `compat40' shopt option.
+
+2.  New Features in Readline
+
+a.  New bindable function: menu-complete-backward.
+
+b.  In the vi insertion keymap, C-n is now bound to menu-complete by default,
+    and C-p to menu-complete-backward.
+
+c.  When in vi command mode, repeatedly hitting ESC now does nothing, even
+    when ESC introduces a bound key sequence.  This is closer to how
+    historical vi behaves.
+
+d.  New bindable function: skip-csi-sequence.  Can be used as a default to
+    consume key sequences generated by keys like Home and End without having
+    to bind all keys.
+
+e.  New application-settable function: rl_filename_rewrite_hook.  Can be used
+    to rewrite or modify filenames read from the file system before they are
+    compared to the word to be completed.
+
+f.  New bindable variable: skip-completed-text, active when completing in the
+    middle of a word.  If enabled, it means that characters in the completion
+    that match characters in the remainder of the word are "skipped" rather
+    than inserted into the line.
+
+g.  The pre-readline-6.0 version of menu completion is available as
+    "old-menu-complete" for users who do not like the readline-6.0 version.
+
+h.  New bindable variable: echo-control-characters.  If enabled, and the
+    tty ECHOCTL bit is set, controls the echoing of characters corresponding
+    to keyboard-generated signals.
+
+i.  New bindable variable: enable-meta-key.  Controls whether or not readline
+    sends the smm/rmm sequences if the terminal indicates it has a meta key
+    that enables eight-bit characters.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-4.0 since
+the release of bash-3.2.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1.  New Features in Bash
+
+a.  When using substring expansion on the positional parameters, a starting
+    index of 0 now causes $0 to be prefixed to the list.
+
+b.  The `help' builtin now prints its columns with entries sorted vertically
+    rather than horizontally.
+
+c.  There is a new variable, $BASHPID, which always returns the process id of
+    the current shell.
+
+d.  There is a new `autocd' option that, when enabled, causes bash to attempt
+    to `cd' to a directory name that is supplied as the first word of a
+    simple command.
+
+e.  There is a new `checkjobs' option that causes the shell to check for and
+    report any running or stopped jobs at exit.
+
+f.  The programmable completion code exports a new COMP_TYPE variable, set to
+    a character describing the type of completion being attempted.
+
+g.  The programmable completion code exports a new COMP_KEY variable, set to
+    the character that caused the completion to be invoked (e.g., TAB).
+
+h.  If creation of a child process fails due to insufficient resources, bash
+    will try again several times before reporting failure.
+
+i.  The programmable completion code now uses the same set of characters as
+    readline when breaking the command line into a list of words.
+
+j.  The block multiplier for the ulimit -c and -f options is now 512 when in
+    Posix mode, as Posix specifies.
+
+k.  Changed the behavior of the read builtin to save any partial input received
+    in the specified variable when the read builtin times out.  This also
+    results in variables specified as arguments to read to be set to the empty
+    string when there is no input available.  When the read builtin times out,
+    it returns an exit status greater than 128.
+
+l.  The shell now has the notion of a `compatibility level', controlled by
+    new variables settable by `shopt'.  Setting this variable currently
+    restores the bash-3.1 behavior when processing quoted strings on the rhs
+    of the `=~' operator to the `[[' command.
+
+m.  The `ulimit' builtin now has new -b (socket buffer size) and -T (number
+    of threads) options.
+
+n.  The -p option to `declare' now displays all variable values and attributes
+    (or function values and attributes if used with -f).
+
+o.  There is a new `compopt' builtin that allows completion functions to modify
+    completion options for existing completions or the completion currently
+    being executed.
+
+p.  The `read' builtin has a new -i option which inserts text into the reply
+    buffer when using readline.
+
+q.  A new `-E' option to the complete builtin allows control of the default
+    behavior for completion on an empty line.
+
+r.  There is now limited support for completing command name words containing
+    globbing characters.
+
+s.  Changed format of internal help documentation for all builtins to roughly
+    follow man page format.
+
+t.  The `help' builtin now has a new -d option, to display a short description,
+    and a -m option, to print help information in a man page-like format.
+
+u.  There is a new `mapfile' builtin to populate an array with lines from a
+    given file.  The name `readarray' is a synonym.
+
+v.  If a command is not found, the shell attempts to execute a shell function
+    named `command_not_found_handle', supplying the command words as the
+    function arguments.
+
+w.  There is a new shell option: `globstar'.  When enabled, the globbing code
+    treats `**' specially -- it matches all directories (and files within
+    them, when appropriate) recursively.
+
+x.  There is a new shell option: `dirspell'.  When enabled, the filename
+    completion code performs spelling correction on directory names during
+    completion.
+
+y.  The `-t' option to the `read' builtin now supports fractional timeout
+    values.
+
+z.  Brace expansion now allows zero-padding of expanded numeric values and
+    will add the proper number of zeroes to make sure all values contain the
+    same number of digits.
+
+aa. There is a new bash-specific bindable readline function: `dabbrev-expand'.
+    It uses menu completion on a set of words taken from the history list.
+
+bb. The command assigned to a key sequence with `bind -x' now sets two new
+    variables in the environment of the executed command:  READLINE_LINE_BUFFER
+    and READLINE_POINT.  The command can change the current readline line
+    and cursor position by modifying READLINE_LINE_BUFFER and READLINE_POINT,
+    respectively.
+
+cc. There is a new &>> redirection operator, which appends the standard output
+    and standard error to the named file.
+
+dd. The parser now understands `|&' as a synonym for `2>&1 |', which redirects
+    the standard error for a command through a pipe.
+
+ee. The new `;&' case statement action list terminator causes execution to
+    continue with the action associated with the next pattern in the
+    statement rather than terminating the command.
+
+ff. The new `;;&' case statement action list terminator causes the shell to
+    test the next set of patterns after completing execution of the current
+    action, rather than terminating the command.
+
+gg. The shell understands a new variable: PROMPT_DIRTRIM.  When set to an
+    integer value greater than zero, prompt expansion of \w and \W  will
+    retain only that number of trailing pathname components and replace
+    the intervening characters with `...'.
+
+hh. There are new case-modifying word expansions: uppercase (^[^]) and
+    lowercase (,[,]).  They can work on either the first character or
+    array element, or globally.  They accept an optional shell pattern
+    that determines which characters to modify.  There is an optionally-
+    configured feature to include capitalization operators.
+
+ii. The shell provides associative array variables, with the appropriate
+    support to create, delete, assign values to, and expand them.
+
+jj. The `declare' builtin now has new -l (convert value to lowercase upon
+    assignment) and -u (convert value to uppercase upon assignment) options.
+    There is an optionally-configurable -c option to capitalize a value at
+    assignment.
+
+kk. There is a new `coproc' reserved word that specifies a coprocess: an
+    asynchronous command run with two pipes connected to the creating shell.
+    Coprocs can be named.  The input and output file descriptors and the
+    PID of the coprocess are available to the calling shell in variables
+    with coproc-specific names.
+
+ll. A value of 0 for the -t option to `read' now returns success if there is
+    input available to be read from the specified file descriptor.
+
+mm. CDPATH and GLOBIGNORE are ignored when the shell is running in privileged
+    mode.
+
+nn. New bindable readline functions shell-forward-word and shell-backward-word,
+    which move forward and backward words delimited by shell metacharacters
+    and honor shell quoting.
+
+oo.  New bindable readline functions shell-backward-kill-word and shell-kill-word
+    which kill words backward and forward, but use the same word boundaries
+    as shell-forward-word and shell-backward-word.
+
+2.  New Features in Readline
+
+a.  A new variable, rl_sort_completion_matches; allows applications to inhibit
+    match list sorting (but beware: some things don't work right if
+    applications do this).
+
+b.  A new variable, rl_completion_invoking_key; allows applications to discover
+    the key that invoked rl_complete or rl_menu_complete.
+
+c.  The functions rl_block_sigint and rl_release_sigint are now public and
+    available to calling applications who want to protect critical sections
+    (like redisplay).
+
+d.  The functions rl_save_state and rl_restore_state are now public and
+    available to calling applications; documented rest of readline's state
+    flag values.
+
+e.  A new user-settable variable, `history-size', allows setting the maximum
+    number of entries in the history list.
+
+f.  There is a new implementation of menu completion, with several improvements
+    over the old; the most notable improvement is a better `completions
+    browsing' mode.
+
+g.  The menu completion code now uses the rl_menu_completion_entry_function
+    variable, allowing applications to provide their own menu completion
+    generators.
+
+h.  There is support for replacing a prefix  of a pathname with a `...' when
+    displaying possible completions.  This is controllable by setting the
+    `completion-prefix-display-length' variable.  Matches with a common prefix
+    longer than this value have the common prefix replaced with `...'.
+
+i.  There is a new `revert-all-at-newline' variable.  If enabled, readline will
+    undo all outstanding changes to all history lines when `accept-line' is
+    executed.
+
+j.  If the kernel supports it, readline displays special characters
+    corresponding to a keyboard-generated signal when the signal is received.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-3.2 since
+the release of bash-3.1.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1.  New Features in Bash
+
+a.  Changed the parameter pattern replacement functions to not anchor the
+    pattern at the beginning of the string if doing global replacement - that
+    combination doesn't make any sense.
+
+b.  When running in `word expansion only' mode (--wordexp option), inhibit
+    process substitution.
+
+c.  Loadable builtins now work on MacOS X 10.[34].
+
+d.  Shells running in posix mode no longer set $HOME, as POSIX requires.
+
+e.  The code that checks for binary files being executed as shell scripts now
+    checks only for NUL rather than any non-printing character.
+
+f.  Quoting the string argument to the [[ command's  =~ operator now forces
+    string matching, as with the other pattern-matching operators.
+
+2.  New Features in Readline
+
+a.  Calling applications can now set the keyboard timeout to 0, allowing
+    poll-like behavior.
+
+b.  The value of SYS_INPUTRC (configurable at compilation time) is now used as
+    the default last-ditch startup file.
+
+c.  The history file reading functions now allow windows-like \r\n line
+    terminators.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-3.1 since
+the release of bash-3.0.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1.  New Features in Bash
+
+a.  Bash now understands LC_TIME as a special variable so that time display
+    tracks the current locale.
+
+b.  BASH_ARGC, BASH_ARGV, BASH_SOURCE, and BASH_LINENO are no longer created
+    as `invisible' variables and may not be unset.
+
+c.  In POSIX mode, if `xpg_echo' option is enabled, the `echo' builtin doesn't
+    try to interpret any options at all, as POSIX requires.
+
+d.  The `bg' builtin now accepts multiple arguments, as POSIX seems to specify.
+
+e.  Fixed vi-mode word completion and glob expansion to perform tilde
+    expansion.
+
+f.  The `**' mathematic exponentiation operator is now right-associative.
+
+g.  The `ulimit' builtin has new options: -i (max number of pending signals),
+    -q (max size of POSIX message queues), and -x (max number of file locks).
+
+h.  A bare `%' once again expands to the current job when used as a job
+    specifier.
+
+i.  The `+=' assignment operator (append to the value of a string or array) is
+    now supported for assignment statements and arguments to builtin commands
+    that accept assignment statements.
+
+j.  BASH_COMMAND now preserves its value when a DEBUG trap is executed.
+
+k.  The `gnu_errfmt' option is enabled automatically if the shell is running
+    in an emacs terminal window.
+
+l.  New configuration option:  --single-help-strings.  Causes long help text
+    to be written as a single string; intended to ease translation.
+
+m.  The COMP_WORDBREAKS variable now causes the list of word break characters
+    to be emptied when the variable is unset.
+
+n.  An unquoted expansion of $* when $IFS is empty now causes the positional
+    parameters to be concatenated if the expansion doesn't undergo word
+    splitting.
+
+o.  Bash now inherits $_ from the environment if it appears there at startup.
+
+p.  New shell option: nocasematch.  If non-zero, shell pattern matching ignores
+    case when used by `case' and `[[' commands.
+
+q.  The `printf' builtin takes a new option: -v var.  That causes the output
+    to be placed into var instead of on stdout.
+
+r.  By default, the shell no longer reports processes dying from SIGPIPE.
+
+s.  Bash now sets the extern variable `environ' to the export environment it
+    creates, so C library functions that call getenv() (and can't use the
+    shell-provided replacement) get current values of environment variables.
+
+t.  A new configuration option, `--enable-strict-posix-default', which will
+    build bash to be POSIX conforming by default.
+
+u.  If compiled for strict POSIX conformance, LINES and COLUMNS may now
+    override the true terminal size.
+
+2.  New Features in Readline
+
+a.  The key sequence sent by the keypad `delete' key is now automatically
+    bound to delete-char.
+
+b.  A negative argument to menu-complete now cycles backward through the
+    completion list.
+
+c.  A new bindable readline variable:  bind-tty-special-chars.  If non-zero,
+    readline will bind the terminal special characters to their readline
+    equivalents when it's called (on by default).
+
+d.  New bindable command: vi-rubout.  Saves deleted text for possible
+    reinsertion, as with any vi-mode `text modification' command; `X' is bound
+    to this in vi command mode.
+
+e.  A new external application-controllable variable that allows the LINES
+    and COLUMNS environment variables to set the window size regardless of
+    what the kernel returns: rl_prefer_env_winsize
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-3.0 since
+the release of bash-2.05b.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1.  New Features in Bash
+
+a.  ANSI string expansion now implements the \x{hexdigits} escape.
+
+b.  There is a new loadable `strftime' builtin.
+
+c.  New variable, COMP_WORDBREAKS, which controls the readline completer's
+    idea of word break characters.
+
+d.  The `type' builtin no longer reports on aliases unless alias expansion
+    will actually be performed.    
+
+e.  HISTCONTROL is now a colon-separated list of values, which permits
+    more extensibility and backwards compatibility.
+
+f.  HISTCONTROL may now include the `erasedups' option, which causes all lines
+    matching a line being added to be removed from the history list.
+
+g.  `configure' has a new `--enable-multibyte' argument that permits multibyte
+    character support to be disabled even on systems that support it.
+
+h.  New variables to support the bash debugger:  BASH_ARGC, BASH_ARGV,
+    BASH_SOURCE, BASH_LINENO, BASH_SUBSHELL, BASH_EXECUTION_STRING,
+    BASH_COMMAND
+
+i.  FUNCNAME has been changed to support the debugger: it's now an array
+    variable.
+
+j.  for, case, select, arithmetic commands now keep line number information
+    for the debugger.
+
+k.  There is a new `RETURN' trap executed when a function or sourced script
+    returns (not inherited child processes; inherited by command substitution
+    if function tracing is enabled and the debugger is active).
+
+l.  New invocation option:  --debugger.  Enables debugging and turns on new
+    `extdebug' shell option.
+
+m.  New `functrace' and `errtrace' options to `set -o' cause DEBUG and ERR
+    traps, respectively, to be inherited by shell functions.  Equivalent to
+    `set -T' and `set -E' respectively.  The `functrace' option also controls
+    whether or not the DEBUG trap is inherited by sourced scripts.
+
+n.  The DEBUG trap is run before binding the variable and running the action
+    list in a `for' command, binding the selection variable and running the
+    query in a `select' command, and before attempting a match in a `case'
+    command.
+
+o.  New `--enable-debugger' option to `configure' to compile in the debugger
+    support code.
+
+p.  `declare -F' now prints out extra line number and source file information
+    if the `extdebug' option is set.
+
+q.  If `extdebug' is enabled, a non-zero return value from a DEBUG trap causes
+    the next command to be skipped, and a return value of 2 while in a
+    function or sourced script forces a `return'.
+
+r.  New `caller' builtin to provide a call stack for the bash debugger.
+
+s.  The DEBUG trap is run just before the first command in a function body is
+    executed, for the debugger.
+
+t.  `for', `select', and `case' command heads are printed when `set -x' is
+    enabled.
+
+u.  There is a new {x..y} brace expansion, which is shorthand for {x.x+1,
+    x+2,...,y}.  x and y can be integers or single characters; the sequence
+    may ascend or descend; the increment is always 1.
+
+v.  New ksh93-like ${!array[@]} expansion, expands to all the keys (indices)
+    of array.
+
+w.  New `force_fignore' shopt option; if enabled, suffixes specified by
+    FIGNORE cause words to be ignored when performing word completion even
+    if they're the only possibilities.
+
+x.  New `gnu_errfmt' shopt option; if enabled, error messages follow the `gnu
+    style' (filename:lineno:message) format.
+
+y.  New `-o bashdefault' option to complete and compgen; if set, causes the
+    whole set of bash completions to be performed if the compspec doesn't
+    result in a match.
+
+z.  New `-o plusdirs' option to complete and compgen; if set, causes directory
+    name completion to be performed and the results added to the rest of the
+    possible completions.
+
+aa. `kill' is available as a builtin even when the shell is built without
+    job control.
+
+bb. New HISTTIMEFORMAT variable; value is a format string to pass to
+    strftime(3).  If set and not null, the `history' builtin prints out
+    timestamp information according to the specified format when displaying
+    history entries.  If set, bash tells the history library to write out
+    timestamp information when the history file is written.
+
+cc. The [[ ... ]] command has a new binary `=~' operator that performs
+    extended regular expression (egrep-like) matching.
+
+dd. `configure' has a new `--enable-cond-regexp' option (enabled by default)
+    to enable the =~ operator and regexp matching in [[ ... ]].
+
+ee. Subexpressions matched by the =~ operator are placed in the new
+    BASH_REMATCH array variable.
+
+ff. New `failglob' option that causes an expansion error when pathname
+    expansion fails to produce a match.
+
+gg. New `set -o pipefail' option that causes a pipeline to return a failure
+    status if any of the processes in the pipeline fail, not just the last
+    one.
+
+hh. printf builtin understands two new escape sequences:  \" and \?.
+
+ii. `echo -e' understands two new escape sequences:  \" and \?.
+
+jj. The GNU `gettext' package and libintl have been integrated; the shell's
+    messages can be translated into different languages.
+
+kk. The `\W' prompt expansion now abbreviates $HOME as `~', like `\w'.
+
+ll. The error message printed when bash cannot open a shell script supplied
+    as argument 1 now includes the name of the shell, to better identify
+    the error as coming from bash.
+
+mm. The parameter pattern removal and substitution expansions are now much
+    faster and more efficient when using multibyte characters.
+
+nn. The `jobs', `kill', and `wait' builtins now accept job control notation
+    even if job control is not enabled.
+
+oo. The historical behavior of `trap' that allows a missing `action' argument
+    to cause each specified signal's handling to be reset to its default is
+    now only supported when `trap' is given a single non-option argument.
+
+2.  New Features in Readline
+
+a.  History expansion has a new `a' modifier equivalent to the `g' modifier
+    for compatibility with the BSD csh.
+
+b.  History expansion has a new `G' modifier equivalent to the BSD csh `g'
+    modifier, which performs a substitution once per word.
+
+c.  All non-incremental search operations may now undo the operation of
+    replacing the current line with the history line.
+
+d.  The text inserted by an `a' command in vi mode can be reinserted with
+    `.'.
+
+e.  New bindable variable, `show-all-if-unmodified'.  If set, the readline
+    completer will list possible completions immediately if there is more
+    than one completion and partial completion cannot be performed.
+
+f.  There is a new application-callable `free_history_entry()' function.
+
+g.  History list entries now contain timestamp information; the history file
+    functions know how to read and write timestamp information associated
+    with each entry.
+
+h.  Four new key binding functions have been added:
+
+	rl_bind_key_if_unbound()
+	rl_bind_key_if_unbound_in_map()
+	rl_bind_keyseq_if_unbound()
+	rl_bind_keyseq_if_unbound_in_map()
+
+i.  New application variable, rl_completion_quote_character, set to any
+    quote character readline finds before it calls the application completion
+    function.
+
+j.  New application variable, rl_completion_suppress_quote, settable by an
+    application completion function.  If set to non-zero, readline does not
+    attempt to append a closing quote to a completed word.
+
+k.  New application variable, rl_completion_found_quote, set to a non-zero
+    value if readline determines that the word to be completed is quoted.
+    Set before readline calls any application completion function.
+
+l.  New function hook, rl_completion_word_break_hook, called when readline
+    needs to break a line into words when completion is attempted.  Allows
+    the word break characters to vary based on position in the line.
+
+m.  New bindable command: unix-filename-rubout.  Does the same thing as
+    unix-word-rubout, but adds `/' to the set of word delimiters.
+
+n.  When listing completions, directories have a `/' appended if the
+    `mark-directories' option has been enabled.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.05b since
+the release of bash-2.05a.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1.  New Features in Bash
+
+a.  If set, TMOUT is the default timeout for the `read' builtin.
+
+b.  `type' has two new options:  `-f' suppresses shell function lookup, and
+    `-P' forces a $PATH search.
+
+c.  New code to handle multibyte characters.
+
+d.  `select' was changed to be more ksh-compatible, in that the menu is
+    reprinted each time through the loop only if REPLY is set to NULL.
+    The previous behavior is available as a compile-time option.
+
+e.  `complete -d' and `complete -o dirnames' now force a slash to be
+    appended to names which are symlinks to directories.
+
+f.  There is now a bindable edit-and-execute-command readline command,
+    like the vi-mode `v' command, bound to C-xC-e in emacs mode.
+
+g.  Added support for ksh93-like [:word:] character class in pattern matching.
+
+h.  The  $'...' quoting construct now expands \cX to Control-X.
+
+i.  A new \D{...} prompt expansion; passes the `...' to strftime and inserts
+    the result into the expanded prompt.
+
+j.  The shell now performs arithmetic in the largest integer size the
+    machine supports (intmax_t), instead of long.
+
+k.  If a numeric argument is supplied to one of the bash globbing completion
+    functions, a `*' is appended to the word before expansion is attempted.
+
+l.  The bash globbing completion functions now allow completions to be listed
+    with double tabs or if `show-all-if-ambiguous' is set.
+
+m.  New `-o nospace' option for `complete' and `compgen' builtins; suppresses
+    readline's appending a space to the completed word.
+
+n.  New `here-string' redirection operator:  <<< word.
+
+o.  When displaying variables, function attributes and definitions are shown
+    separately, allowing them to be re-used as input (attempting to re-use
+    the old output would result in syntax errors).
+
+p.  There is a new configuration option `--enable-mem-scramble', controls
+    bash malloc behavior of writing garbage characters into memory at
+    allocation and free time.
+
+q.  The `complete' and `compgen' builtins now have a new `-s/-A service'
+    option to complete on names from /etc/services.
+
+r.  `read' has a new `-u fd' option to read from a specified file descriptor.
+
+s.  Fix the completion code so that expansion errors in a directory name
+    don't cause a longjmp back to the command loop.
+
+t.  Fixed word completion inside command substitution to work a little more
+    intuitively.
+
+u.  The `printf' %q format specifier now uses $'...' quoting to print the
+    argument if it contains non-printing characters.
+
+v.  The `declare' and `typeset' builtins have a new `-t' option.  When applied
+    to functions, it causes the DEBUG trap to be inherited by the named
+    function.  Currently has no effect on variables.
+
+w.  The DEBUG trap is now run *before* simple commands, ((...)) commands,
+    [[...]] conditional commands, and for ((...)) loops.
+
+x.  The expansion of $LINENO inside a shell function is only relative to the
+    function start if the shell is interactive -- if the shell is running a
+    script, $LINENO expands to the line number in the script.  This is as
+    POSIX-2001 requires.
+
+y.  The bash debugger in examples/bashdb has been modified to work with the
+    new DEBUG trap semantics, the command set has been made more gdb-like,
+    and the changes to $LINENO make debugging functions work better.  Code
+    from Gary Vaughan.
+
+z.  New [n]<&word- and [n]>&word- redirections from ksh93 -- move fds (dup
+    and close).
+
+aa. There is a new `-l' invocation option, equivalent to `--login'.
+
+bb. The `hash' builtin has a new `-l' option to list contents in a reusable
+    format, and a `-d' option to remove a name from the hash table.
+
+cc. There is now support for placing the long help text into separate files 
+    installed into ${datadir}/bash.  Not enabled by default; can be turned  
+    on with `--enable-separate-helpfiles' option to configure.
+    
+dd. All builtins that take operands accept a `--' pseudo-option, except
+    `echo'.
+
+ee. The `echo' builtin now accepts \0xxx (zero to three octal digits following
+    the `0') in addition to \xxx (one to three octal digits) for SUSv3/XPG6/
+    POSIX.1-2001 compliance.
+
+
+2.  New Features in Readline
+
+a.  Support for key `subsequences':  allows, e.g., ESC and ESC-a to both
+    be bound to readline functions.  Now the arrow keys may be used in vi
+    insert mode.
+
+b.  When listing completions, and the number of lines displayed is more than
+    the screen length, readline uses an internal pager to display the results.
+    This is controlled by the `page-completions' variable (default on).
+
+c.  New code to handle editing and displaying multibyte characters.
+
+d.  The behavior introduced in bash-2.05a of deciding whether or not to
+    append a slash to a completed name that is a symlink to a directory has
+    been made optional, controlled by the `mark-symlinked-directories'
+    variable (default is the 2.05a behavior).
+
+e.  The `insert-comment' command now acts as a toggle if given a numeric
+    argument:  if the first characters on the line don't specify a
+    comment, insert one; if they do, delete the comment text
+
+f.  New application-settable completion variable:
+    rl_completion_mark_symlink_dirs, allows an application's completion
+    function to temporarily override the user's preference for appending
+    slashes to names which are symlinks to directories.
+
+g.  New function available to application completion functions:
+    rl_completion_mode, to tell how the completion function was invoked
+    and decide which argument to supply to rl_complete_internal (to list
+    completions, etc.).
+
+h.  Readline now has an overwrite mode, toggled by the `overwrite-mode'
+    bindable command, which could be bound to `Insert'.
+
+i.  New application-settable completion variable:
+    rl_completion_suppress_append, inhibits appending of
+    rl_completion_append_character to completed words.
+
+j.  New key bindings when reading an incremental search string:  ^W yanks
+    the currently-matched word out of the current line into the search
+    string; ^Y yanks the rest of the current line into the search string,
+    DEL or ^H deletes characters from the search string.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.05a since
+the release of bash-2.05.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1.  New Features in Bash
+
+a.  Added support for DESTDIR installation root prefix, so you can do a
+    `make install DESTDIR=bash-root' and do easier binary packaging.
+
+b.  Added support for builtin printf "'" flag character as per latest POSIX
+    drafts.
+
+c.  Support for POSIX.2 printf(1) length specifiers `j', `t', and `z' (from
+    ISO C99).
+
+d.  New autoconf macro, RL_LIB_READLINE_VERSION, for use by other applications
+    (bash doesn't use very much of what it returns).
+
+e.  `set [-+]o nolog' is recognized as required by the latest POSIX drafts,
+    but ignored.
+
+f.  New read-only `shopt' option:  login_shell.  Set to non-zero value if the
+    shell is a login shell.
+
+g.  New `\A' prompt string escape sequence; expands to time in 24 HH:MM format.
+
+h.  New `-A group/-g' option to complete and compgen; does group name
+    completion.
+
+i.  New `-t' option to `hash' to list hash values for each filename argument.
+
+j.  New [-+]O invocation option to set and unset `shopt' options at startup.
+
+k.  configure's `--with-installed-readline' option now takes an optional
+    `=PATH' suffix to set the root of the tree where readline is installed
+    to PATH.
+
+l.  The ksh-like `ERR' trap has been added.  The `ERR' trap will be run
+    whenever the shell would have exited if the -e option were enabled.
+    It is not inherited by shell functions.
+
+m.  `readonly', `export', and `declare' now print variables which have been
+    given attributes but not set by assigning a value as just a command and
+    a variable name (like `export foo') when listing, as the latest POSIX
+    drafts require.
+
+n.  `bashbug' now requires that the subject be changed from the default.
+
+o.  configure has a new `--enable-largefile' option, like other GNU utilities.
+
+p.  `for' loops now allow empty word lists after `in', like the latest POSIX
+    drafts require.
+
+q.  The builtin `ulimit' now takes two new non-numeric arguments:  `hard',
+    meaning the current hard limit, and `soft', meaning the current soft  
+    limit, in addition to `unlimited'
+    
+r.  `ulimit' now prints the option letter associated with a particular
+    resource when printing more than one limit.
+
+s.  `ulimit' prints `hard' or `soft' when a value is not `unlimited' but is
+    one of RLIM_SAVED_MAX or RLIM_SAVED_CUR, respectively.
+
+t.  The `printf' builtin now handles the %a and %A conversions if they're
+    implemented by printf(3).
+
+u.  The `printf' builtin now handles the %F conversion (just about like %f).
+
+v.  The `printf' builtin now handles the %n conversion like printf(3).  The
+    corresponding argument is the name of a shell variable to which the
+    value is assigned.
+
+2.  New Features in Readline
+
+a.  Added extern declaration for rl_get_termcap to readline.h, making it a
+    public function (it was always there, just not in readline.h).
+
+b.  New #defines in readline.h:  RL_READLINE_VERSION, currently 0x0402,
+    RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2.
+
+c.  New readline variable:  rl_readline_version, mirrors RL_READLINE_VERSION.
+
+d.  New bindable boolean readline variable:  match-hidden-files.  Controls
+    completion of files beginning with a `.' (on Unix).  Enabled by default.
+
+e.  The history expansion code now allows any character to terminate a
+    `:first-' modifier, like csh.
+
+f.  New bindable variable `history-preserve-point'.  If set, the history
+    code attempts to place the user at the same location on each history
+    line retrieved with previous-history or next-history.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.05 since
+the release of bash-2.04.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1.  New Features in Bash
+
+a.  Added a new `--init-file' invocation argument as a synonym for `--rcfile',
+    per the new GNU coding standards.
+
+b.  The /dev/tcp and /dev/udp redirections now accept service names as well as
+    port numbers.
+
+c.  `complete' and `compgen' now take a `-o value' option, which controls some
+    of the aspects of that compspec.  Valid values are:
+
+        default - perform bash default completion if programmable
+                  completion produces no matches
+        dirnames - perform directory name completion if programmable
+                   completion produces no matches
+        filenames - tell readline that the compspec produces filenames,
+                    so it can do things like append slashes to
+                    directory names and suppress trailing spaces
+
+d.  A new loadable builtin, realpath, which canonicalizes and expands symlinks
+    in pathname arguments.
+    
+e.  When `set' is called without options, it prints function definitions in a
+    way that allows them to be reused as input.  This affects `declare' and 
+    `declare -p' as well.  This only happens when the shell is not in POSIX
+    mode, since POSIX.2 forbids this behavior.
+
+f.  Bash-2.05 once again honors the current locale setting when processing
+    ranges within pattern matching bracket expressions (e.g., [A-Z]).
+
+2.  New Features in Readline
+
+a.  The blink timeout for paren matching is now settable by applications,
+    via the rl_set_paren_blink_timeout() function.
+
+b.  _rl_executing_macro has been renamed to rl_executing_macro, which means
+    it's now part of the public interface.
+
+c.  Readline has a new variable, rl_readline_state, which is a bitmap that
+    encapsulates the current state of the library; intended for use by
+    callbacks and hook functions.
+
+d.  New application-callable function rl_set_prompt(const char *prompt):
+    expands its prompt string argument and sets rl_prompt to the result.
+
+e.  New application-callable function rl_set_screen_size(int rows, int cols):
+    public method for applications to set readline's idea of the screen
+    dimensions.
+
+f.  New function, rl_get_screen_size (int *rows, int *columns), returns
+    readline's idea of the screen dimensions.
+
+g.  The timeout in rl_gather_tyi (readline keyboard input polling function)
+    is now settable via a function (rl_set_keyboard_input_timeout()).
+
+h.  Renamed the max_input_history variable to history_max_entries; the old
+    variable is maintained for backwards compatibility.
+
+i.  The list of characters that separate words for the history tokenizer is
+    now settable with a variable:  history_word_delimiters.  The default
+    value is as before.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.04 since
+the release of bash-2.03.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1.  New Features in Bash
+
+a.  The history builtin has a `-d offset' option to delete the history entry
+    at position `offset'.
+
+b.  The prompt expansion code has two new escape sequences: \j, the number of
+    active jobs; and \l, the basename of the shell's tty device name.
+
+c.  The `bind' builtin has a new `-x' option to bind key sequences to shell   
+    commands.
+
+d.  There is a new shell option, no_empty_command_completion, which, when
+    enabled, disables command completion when TAB is typed on an empty line.
+
+e.  The `help' builtin has a `-s' option to just print a builtin's usage
+    synopsis.
+
+f.  There are several new arithmetic operators:  id++, id-- (variable
+    post-increment/decrement), ++id, --id (variable pre-increment/decrement),
+    expr1 , expr2 (comma operator).
+
+g.  There is a new ksh-93 style arithmetic for command:
+        for ((expr1 ; expr2; expr3 )); do list; done
+
+h.  The `read' builtin has a number of new options:
+        -t timeout      only wait timeout seconds for input
+        -n nchars       only read nchars from input instead of a full line
+        -d delim        read until delim rather than newline
+        -s              don't echo input chars as they are read
+
+i.  The redirection code now handles several filenames specially:
+    /dev/fd/N, /dev/stdin, /dev/stdout, and /dev/stderr, whether or
+    not they are present in the file system.
+
+j.  The redirection code now recognizes pathnames of the form
+    /dev/tcp/host/port and /dev/udp/host/port, and tries to open a socket
+    of the appropriate type to the specified port on the specified host.
+
+k.  The ksh-93 ${!prefix*} expansion, which expands to the names of all
+    shell variables with prefix PREFIX, has been implemented.
+
+l.  There is a new dynamic variable, FUNCNAME, which expands to the name of
+    a currently-executing function.  Assignments to FUNCNAME have no effect.
+
+m.  The GROUPS variable is no longer readonly; assignments to it are silently
+    discarded.  This means it can be unset.
+
+n.  A new programmable completion facility, with two new builtin commands:
+    complete and compgen.
+
+o.  configure has a new option, `--enable-progcomp', to compile in the
+    programmable completion features (enabled by default).
+
+p.  `shopt' has a new option, `progcomp', to enable and disable programmable
+    completion at runtime.
+
+q.  Unsetting HOSTFILE now clears the list of hostnames used for completion.
+
+r.  configure has a new option, `--enable-bash-malloc', replacing the old
+    `--with-gnu-malloc' (which is still present for backwards compatibility).
+
+s.  There is a new manual page describing rbash, the restricted shell.
+
+t.  `bashbug' has new `--help' and `--version' options.
+
+u.  `shopt' has a new `xpg_echo' option, which controls the behavior of
+    `echo' with respect to backslash-escaped characters at runtime.
+
+v.  If NON_INTERACTIVE_LOGIN_SHELLS is defined, all login shells read the
+    startup files, even if they are not interactive.
+
+w.  The LC_NUMERIC variable is now treated specially, and used to set the
+    LC_NUMERIC locale category for number formatting, e.g., when `printf'
+    displays floating-point numbers.
+
+2.  New features in Readline
+
+a.  Parentheses matching is now always compiled into readline, and enabled
+    or disabled when the value of the `blink-matching-paren' variable is
+    changed.
+
+b.  MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename.
+
+c.  MS-DOS systems now use ~/_history as the default history file.
+
+d.  history-search-{forward,backward} now leave the point at the end of the
+    line when the string to search for is empty, like
+    {reverse,forward}-search-history.
+
+e.  history-search-{forward,backward} now leave the last history line found
+    in the readline buffer if the second or subsequent search fails.
+
+f.  New function for use by applications:  rl_on_new_line_with_prompt, used
+    when an application displays the prompt itself before calling readline().
+
+g.  New variable for use by applications:  rl_already_prompted.  An application
+    that displays the prompt itself before calling readline() must set this to
+    a non-zero value.
+
+h.  A new variable, rl_gnu_readline_p, always 1.  The intent is that an
+    application can verify whether or not it is linked with the `real'
+    readline library or some substitute.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.03 since
+the release of bash-2.02.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1.  New Features in Bash
+
+a.  New `shopt' option, `restricted_shell', indicating whether or not the
+    shell was started in restricted mode, for use in startup files.
+
+b.  Filename generation is now performed on the words between ( and ) in
+    array assignments (which it probably should have done all along).
+
+c.  OLDPWD is now auto-exported, as POSIX.2 seems to require.
+
+d.  ENV and BASH_ENV are read-only variables in a restricted shell.
+
+e.  A change was made to the startup file code so that any shell begun with
+    the `--login' option, even non-interactive shells, will source the login
+    shell startup files.
+
+2.  New Features in Readline
+
+a.  Many changes to the signal handling:
+        o Readline now catches SIGQUIT and cleans up the tty before returning;
+        o A new variable, rl_catch_signals, is available to application writers 
+          to indicate to readline whether or not it should install its own
+          signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP,
+          SIGTTIN, and SIGTTOU;
+        o A new variable, rl_catch_sigwinch, is available to application
+          writers to indicate to readline whether or not it should install its
+          own signal handler for SIGWINCH, which will chain to the calling
+          applications's SIGWINCH handler, if one is installed;
+        o There is a new function, rl_free_line_state, for application signal
+          handlers to call to free up the state associated with the current
+          line after receiving a signal;
+        o There is a new function, rl_cleanup_after_signal, to clean up the
+          display and terminal state after receiving a signal;
+        o There is a new function, rl_reset_after_signal, to reinitialize the
+          terminal and display state after an application signal handler
+          returns and readline continues
+
+b.  There is a new function, rl_resize_terminal, to reset readline's idea of
+    the screen size after a SIGWINCH.
+
+c.  New public functions: rl_save_prompt and rl_restore_prompt.  These were
+    previously private functions with a `_' prefix.
+
+d.  New function hook: rl_pre_input_hook, called just before readline starts
+    reading input, after initialization.
+
+e.  New function hook: rl_display_matches_hook, called when readline would
+    display the list of completion matches.  The new function
+    rl_display_match_list is what readline uses internally, and is available
+    for use by application functions called via this hook.
+
+f.  New bindable function, delete-char-or-list, like tcsh.
+
+g.  A new variable, rl_erase_empty_line, which, if set by an application using
+    readline, will cause readline to erase, prompt and all, lines on which the
+    only thing typed was a newline.
+
+h.  New bindable variable: `isearch-terminators'.
+
+i.  New bindable function: `forward-backward-delete-char' (unbound by default).
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.02 since
+the release of bash-2.01.1.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a.  A new version of malloc, based on the older GNU malloc, that has many
+    changes, is more page-based, is more conservative with memory usage,
+    and does not `orphan' large blocks when they are freed.
+
+b.  A new version of gmalloc, based on the old GLIBC malloc, with many
+    changes and range checking included by default.
+
+c.  A new implementation of fnmatch(3) that includes full POSIX.2 Basic
+    Regular Expression matching, including character classes, collating
+    symbols, equivalence classes, and support for case-insensitive pattern
+    matching.
+
+d.  ksh-88 egrep-style extended pattern matching ([@+*?!](patlist)) has been
+    implemented, controlled by a new `shopt' option, `extglob'.  
+    
+e.  There is a new ksh-like `[[' compound command, which implements   
+    extended `test' functionality.
+    
+f.  There is a new `printf' builtin, implemented according to the POSIX.2
+    specification.
+    
+g.  There is a new feature for command substitution: $(< filename) now expands
+    to the contents of `filename', with any trailing newlines removed
+    (equivalent to $(cat filename)).
+
+h.  There are new tilde prefixes which expand to directories from the
+    directory stack.
+
+i.  There is a new `**' arithmetic operator to do exponentiation.
+
+j.  There are new configuration options to control how bash is linked:
+    `--enable-profiling', to allow bash to be profiled with gprof, and
+    `--enable-static-link', to allow bash to be linked statically.
+
+k.  There is a new configuration option, `--enable-cond-command', which
+    controls whether or not the `[[' command is included.  It is on by
+    default. 
+
+l.  There is a new configuration option, `--enable-extended-glob', which
+    controls whether or not the ksh extended globbing feature is included.
+    It is enabled by default.
+
+m.  There is a new configuration #define in config.h.top that, when enabled,
+    will cause all login shells to source /etc/profile and one of the user-
+    specific login shell startup files, whether or not the shell is
+    interactive.  
+    
+n.  There is a new invocation option, `--dump-po-strings', to dump
+    a shell script's translatable strings ($"...") in GNU `po' format. 
+    
+o.  There is a new `shopt' option, `nocaseglob', to enable case-insensitive
+    pattern matching when globbing filenames and using the `case' construct.
+
+p.  There is a new `shopt' option, `huponexit', which, when enabled, causes
+    the shell to send SIGHUP to all jobs when an interactive login shell
+    exits.
+
+q.  `bind' has a new `-u' option, which takes a readline function name as an
+    argument and unbinds all key sequences bound to that function in a
+    specified keymap.
+    
+r.  `disown' now has `-a' and `-r' options, to limit operation to all jobs
+    and running jobs, respectively.
+
+s.  The `shopt' `-p' option now causes output to be displayed in a reusable
+    format.
+    
+t.  `test' has a new `-N' option, which returns true if the filename argument
+    has been modified since it was last accessed.
+
+u.  `umask' now has a `-p' option to print output in a reusable format.
+    
+v.  A new escape sequence, `\xNNN', has been added to the `echo -e' and $'...'
+    translation code.  It expands to the character whose ascii code is NNN
+    in hexadecimal.
+    
+w.  The prompt string expansion code has a new `\r' escape sequence.
+
+x.  The shell may now be cross-compiled for the CYGWIN32 environment on
+    a Unix machine.
+
+2. New Features in Readline
+
+a.  There is now an option for `iterative' yank-last-arg handline, so a user
+    can keep entering `M-.', yanking the last argument of successive history
+    lines.
+
+b.  New variable, `print-completions-horizontally', which causes completion
+    matches to be displayed across the screen (like `ls -x') rather than up
+    and down the screen (like `ls').
+
+c.  New variable, `completion-ignore-case', which causes filename completion
+    and matching to be performed case-insensitively.
+
+d.  There is a new bindable command, `magic-space', which causes history
+    expansion to be performed on the current readline buffer and a space to
+    be inserted into the result.
+
+e.  There is a new bindable command, `menu-complete', which enables tcsh-like
+    menu completion (successive executions of menu-complete insert a single
+    completion match, cycling through the list of possible completions).
+
+f.  There is a new bindable command, `paste-from-clipboard', for use on Win32
+    systems, to insert the text from the Win32 clipboard into the editing
+    buffer.
+
+g.  The key sequence translation code now understands printf-style backslash
+    escape sequences, including \NNN octal escapes.  These escape sequences
+    may be used in key sequence definitions or macro values.
+
+h.  An `$include' inputrc file parser directive has been added.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.01 since
+the release of bash-2.0.  As always, the manual page (doc/bash.1) is the
+place to look for complete descriptions.
+
+1. New Features in Bash
+
+a.  There is a new builtin array variable: GROUPS, the set of groups to which
+    the user belongs.  This is used by the test suite.
+
+2.  New Features in Readline
+
+a.  If a key sequence bound to `universal-argument' is read while reading a
+    numeric argument started with `universal-argument', it terminates the
+    argument but is otherwise ignored.  This provides a way to insert multiple
+    instances of a digit string, and is how GNU emacs does it.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.0 since
+the release of bash-1.14.7.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1.  New Features in Bash
+
+a.  There is a new invocation option, -D, that dumps translatable strings
+    in a script.
+
+b.  The `long' invocation options must now be prefixed with `--'.
+
+c.  New long invocation options:  --dump-strings, --help, --verbose
+
+d.  The `nolineediting' invocation option was renamed to `noediting'.
+
+e.  The `nobraceexpansion' and `quiet' long invocation options were removed.
+
+f.  The `--help' and `--version' long options now work as the GNU coding
+    standards specify.
+
+g.  If invoked as `sh', bash now enters posix mode after reading the
+    startup files, and reads and executes commands from the file named
+    by $ENV if interactive (as POSIX.2 specifies).  A login shell invoked
+    as `sh' reads $ENV after /etc/profile and ~/.profile.
+
+h.  There is a new reserved word, `time', for timing pipelines, builtin
+    commands, and shell functions.  It uses the value of the TIMEFORMAT
+    variable as a format string describing how to print the timing
+    statistics.
+
+i.  The $'...' quoting syntax expands ANSI-C escapes in ... and leaves the
+    result single-quoted.
+
+j.  The $"..." quoting syntax performs locale-specific translation of ...
+    and leaves the result double-quoted.
+
+k.  LINENO now works correctly in functions.
+
+l.  New variables: DIRSTACK, PIPESTATUS, BASH_VERSINFO, HOSTNAME, SHELLOPTS,
+    MACHTYPE.  The first three are array variables.
+
+m.  The BASH_VERSION and BASH_VERSINFO variables now include the shell's
+    `release status' (alpha[N], beta[N], release).
+
+n.  Some variables have been removed:  MAIL_WARNING, notify, history_control,
+    command_oriented_history, glob_dot_filenames, allow_null_glob_expansion,
+    nolinks, hostname_completion_file, noclobber, no_exit_on_failed_exec, and
+    cdable_vars.  Most of them are now implemented with the new `shopt'
+    builtin; others were already implemented by `set'.
+
+o.  Bash now uses some new variables:  LC_ALL, LC_MESSAGES, LC_CTYPE,
+    LC_COLLATE, LANG, GLOBIGNORE, HISTIGNORE.
+
+p.  The shell now supports integer-indexed arrays of unlimited length,
+    with a new compound assignment syntax and changes to the appropriate
+    builtin commands (declare/typeset, read, readonly, etc.).  The array
+    index may be an arithmetic expression.
+
+q.  ${!var}: indirect variable expansion, equivalent to eval \${$var}.
+
+r.  ${parameter:offset[:length]}: variable substring extraction.
+
+s.  ${parameter/pattern[/[/]string]}: variable pattern substitution.
+
+t.  The $[...] arithmetic expansion syntax is no longer supported, in
+    favor of $((...)).
+
+u.  Aliases can now be expanded in shell scripts with a shell option
+    (shopt expand_aliases).
+
+v.  History and history expansion can now be used in scripts with
+    set -o history and set -H.
+
+w.  All builtins now return an exit status of 2 for incorrect usage.
+
+x.  Interactive shells resend SIGHUP to all running or stopped children
+    if (and only if) they exit due to a SIGHUP.
+
+y.  New prompting expansions: \a, \e, \H, \T, \@, \v, \V.
+
+z.  Variable expansion in prompt strings is now controllable via a shell
+    option (shopt promptvars).
+
+aa. Bash now defaults to using command-oriented history.
+
+bb. The history file ($HISTFILE) is now truncated to $HISTFILESIZE after
+    being written.
+
+cc. The POSIX.2 conditional arithmetic evaluation syntax (expr ? expr : expr)
+    has been implemented.
+
+dd. Each builtin now accepts `--' to signify the end of the options, except
+    as documented (echo, etc.).
+
+ee. All builtins use -p to display values in a re-readable format where
+    appropriate, except as documented (echo, type, etc.).
+
+ff. The `alias' builtin has a new -p option.
+
+gg. Changes to the `bind' builtin:
+	o has new options: -psPSVr.
+	o the `-d' option was renamed to `-p'
+	o the `-v' option now dumps variables; the old `-v' is now `-P'
+
+hh. The `bye' synonym for `exit' was removed.
+
+ii. The -L and -P options to `cd' and `pwd' have been documented.
+
+jj. The `cd' builtin now does spelling correction on the directory name
+    by default.  This is settable with a shell option (shopt cdspell).
+
+kk. The `declare' builtin has new options: -a, -F, -p.
+
+ll. The `dirs' builtin has new options: -c, -p, -v.
+
+mm. The new `disown' builtin removes jobs from the shell's jobs table
+    or inhibits the resending of SIGHUP when the shell receives a
+    SIGHUP.
+
+nn. The `echo' builtin has a new escape character: \e.
+
+oo. The `enable' builtin can now load new builtins dynamically from shared
+    objects on systems with the dlopen/dlsym interface.  There are a number
+    of examples in the examples/loadables directory.  There are also
+    new options: -d, -f, -s, -p.
+
+pp. The `-all' option to `enable' was removed in favor of `-a'.
+
+qq. The `exec' builtin has new options: -l, -c, -a.
+
+rr. The `hash' builtin has a new option: -p.
+
+ss. The `history' builtin has new options: -c, -p, -s.
+
+tt. The `jobs' builtin has new options: -r, -s.
+
+uu. The `kill' builtin has new options: -n signum, -l signame.
+
+vv. The `pushd' and `popd' builtins have a new option: -n.
+
+ww. The `read' builtin has new options: -p prompt, -e, -a.
+
+xx. The `readonly' builtin has a new -a option, and the -n option was removed.
+
+yy. Changes to the `set' builtin:
+	o new options: -B, -o keyword, -o onecmd, -o history
+	o options removed: -l, -d, -o nohash
+	o options changed: +o, -h, -o hashall
+	o now displays variables in a format that can be re-read as input
+
+zz. The new `shopt' builtin controls shell optional behavior previously
+    done by setting and unsetting certain shell variables.
+
+aaa. The `test' builtin has new operators: -o option, s1 == s2, s1 < s2,
+     and s1 > s2, where s1 and s2 are strings.
+
+bbb. There is a new trap, DEBUG, executed after every simple command.
+
+ccc. The `trap' builtin has a new -p option.
+
+ddd. The `ulimit' builtin has a new -l option on 4.4BSD-based systems.
+
+eee. The PS1, PS2, PATH, and IFS variables may now be unset.
+
+fff. The restricted shell mode has been expanded and is now documented.
+
+ggg. Security improvements:
+	o functions are not imported from the environment if running setuid
+	  or with -p
+	o no startup files are sourced if running setuid or with -p
+
+hhh. The documentation has been overhauled:  the texinfo manual was
+     expanded, and HTML versions of the man page and texinfo manual
+     are included.
+
+iii. Changes to Posix mode:
+	o Command lookup now finds special builtins before shell functions.
+	o Failure of a special builtin causes a non-interactive shell to
+	  exit.  Failures are defined in the POSIX.2 specification.
+	o If the `cd' builtin finds a directory to change to using $CDPATH,
+	  the value assigned to PWD when `cd' completes does not contain
+	  any symbolic links.
+	o A non-interactive shell exits if a variable assignment error
+	  occurs when no command name follows the assignment statements.
+	o A non-interactive shell exits if the iteration variable in a
+	  `for' statement or the selection variable in a `select' statement
+	  is read-only or another variable assignment error occurs.
+	o The `<>' redirection operator now opens a file for both stdin and
+	  stdout by default, not just when in posix mode.
+	o Assignment statements preceding special builtins now persist in
+	  the shell's environment when the builtin completes.
+
+     Posix mode is now completely POSIX.2-compliant (modulo bugs).  When
+     invoked as sh, bash should be completely POSIX.2-compliant.
+
+jjj. The default value of PS1 is now "\s-\v\$ ".
+
+kkk. The ksh-like ((...)) arithmetic command syntax has been implemented.
+     This is exactly equivalent to `let "..."'.
+
+lll. Integer constants have been extended to base 64.
+
+mmm. The `ulimit' builtin now sets both hard and soft limits and reports the
+     soft limit by default.
+
+2.  New Features in Readline
+
+a.  New variables:  enable-keypad, input-meta (new name for meta-flag),
+    mark-directories, visible-stats (now documented), disable-completion,
+    comment-begin.
+
+b.  New bindable commands:  kill-region, copy-region-as-kill,
+    copy-backward-word, copy-forward-word, set-mark, exchange-point-and-mark,
+    character-search, character-search-backward, insert-comment,
+    glob-expand-word, glob-list-expansions, dump-variables, dump-macros.
+
+c.  New emacs keybindings:  delete-horizontal-space (M-\),
+    insert-completions (M-*), possible-completions (M-=).
+
+d.  The history-search-backward and history-search-forward commands were
+    modified to be the same as previous-line and next-line if point is at
+    the start of the line.
+
+e.  More file types are available for the visible-stats mode.
+
+3.  Changes of interest in the Bash implementation
+
+a.  There is a new autoconf-based configuration mechanism.
+
+b.  More things have been moved from Posix mode to standard shell behavior.
+
+c.  The trace output (set -x) now inserts quotes where necessary so it can
+    be reused as input.
+
+d.  There is a compile-time option for a system-wide interactive shell
+    startup file (disabled by default).
+
+e.  The YACC grammar is smaller and tighter, and all 66 shift-reduce
+    conflicts are gone.  Several parsing bugs have been fixed.
+
+f.  Builtin option parsing has been regularized (using internal_getopt()),
+    with the exception of `echo', `type', and `set'.
+
+g.  Builtins now return standard usage messages constructed from the
+    `short doc' used by the help builtin.
+
+h.  Completion now quotes using backslashes by default, but honors
+    user-supplied quotes.
+
+i.  The GNU libc malloc is available as a configure-time option.
+
+j.  There are more internationalization features; bash uses gettext if
+    it is available.  The $"..." translation syntax uses the current
+    locale and gettext.
+
+k.  There is better reporting of job termination when the shell is not
+    interactive.
+
+l.  The shell is somewhat more efficient: it uses a little less memory and
+    makes fewer system calls.
+
+4.  Changes of interest in the Readline implementation
+
+a.  There is now support for readline `callback' functions.
+
+b.  There is now support for user-supplied input, redisplay, and terminal
+    preparation functions.
+
+c.  Most of the shell-specific code in readline has been generalized or
+    removed.
+
+d.  Most of the annoying redisplay bugs have been fixed, notably the problems
+    with incremental search and excessive redrawing when special characters
+    appear in the prompt string.
+
+e.  There are new library functions and variables available to application
+    writers, most having to do with completion and quoting.
+
+f.  The NEWLINE character (^J) is now treated as a search terminator by the
+    incremental search functions.

+Platform-Specific Configuration and Operation Notes [very dated]
+====================================================================
+
+1.  configure --without-gnu-malloc on:
+
+	alpha running OSF/1, Linux, or NetBSD (malloc needs 8-byte alignment;
+	bash malloc has 8-byte alignment now, but I have no alphas to test on)
+
+	next running NeXT/OS; machines running Openstep
+
+	all machines running SunOS YP code: SunOS4, SunOS5, HP/UX, if you
+	have problems with username completion or tilde expansion for
+	usernames found via YP/NIS
+
+	linux (optional, but don't do it if you're using Doug Lea's malloc)
+
+	QNX 4.2
+	other OSF/1 machines (KSR/1, HP, IBM AIX/ESA)
+	AIX
+	sparc SVR4, SVR4.2 (ICL reference port)
+	DG/UX
+	Cray
+	Haiku OS
+
+	NetBSD/sparc (malloc needs 8-byte alignment; bash malloc has 8-byte
+	alignment now, but I have no NetBSD machines to test on)
+
+	BSD/OS 2.1, 3.x if you want to use loadable builtins
+
+	Motorola m68k machines running System V.3.  There is a file descriptor
+	leak caused by using the bash malloc because closedir(3) needs to read
+	freed memory to find the file descriptor to close
+
+2.  Configure using shlicc2 on BSD/OS 2.1 and BSD/OS 3.x to use loadable
+    builtins
+
+3.  Bash cannot be built in a directory separate from the source directory
+    using configure --srcdir=... unless the version of `make' you're using
+    does $VPATH handling right.  The script support/mkclone can be used to
+    create a `build tree' using symlinks to get around this.
+
+4.  I've had reports that username completion (as well as tilde expansion
+    and \u prompt expansion) does not work on IRIX 5.3 when linking with
+    -lnsl.  This is only a problem when you're running NIS, since
+    apparently -lnsl supports only /etc/passwd and not the NIS functions
+    for retrieving usernames and passwords.  Editing the Makefile after
+    configure runs and removing the `-lnsl' from the assignment to `LIBS'
+    fixes the problem.
+
+5.  There is a problem with the `makewhatis' script in older (pre-7.0)
+    versions of Red Hat Linux.  Running `makewhatis' with bash-2.0 or
+    later versions results in error messages like this:
+
+    /usr/sbin/makewhatis: cd: manpath: No such file or directory
+    /usr/sbin/makewhatis: manpath/whatis: No such file or directory
+    chmod: manpath/whatis: No such file or directory
+    /usr/sbin/makewhatis: cd: catpath: No such file or directory
+    /usr/sbin/makewhatis: catpath/whatis: No such file or directory
+    chmod: catpath/whatis: No such file or directory
+
+    The problem is with `makewhatis'.  Red Hat (and possibly other
+    Linux distributors) uses a construct like this in the code:
+
+        eval path=$"$pages"path
+
+    to do indirect variable expansion.  This `happened to work' in
+    bash-1.14 and previous versions, but that was more an accident
+    of implementation than anything else -- it was never supported
+    and certainly is not portable.
+
+    Bash-2.0 has a new feature that gives a new meaning to $"...".
+    This is explained more completely in item 1 in the COMPAT file.
+
+    The three lines in the `makewhatis' script that need to be changed
+    look like this:
+
+             eval $topath=$"$topath":$name
+    [...]
+       eval path=$"$pages"path
+    [...]
+    eval path=$"$pages"path
+
+    The portable way to write this code is
+
+             eval $topath="\$$topath":$name
+       eval path="\$$pages"path
+    eval path="\$$pages"path
+
+    You could also experiment with another new bash feature: ${!var}.
+    This does indirect variable expansion, making the use of eval
+    unnecessary.
+
+6.  There is a problem with syslogd on many Linux distributions (Red Hat
+    and Slackware are two that I have received reports about).  syslogd
+    sends a SIGINT to its parent process, which is waiting for the daemon
+    to finish its initialization.  The parent process then dies due to
+    the SIGINT, and bash reports it, causing unexpected console output
+    while the system is booting that looks something like
+
+	starting daemons: syslogd/etc/rc.d/rc.M: line 29: 38 Interrupt ${NET}/syslogd
+
+    Bash-2.0 reports events such as processes dying in scripts due to
+    signals when the standard output is a tty.  Bash-1.14.x and previous
+    versions did not report such events.
+
+    This should probably be reported as a bug to whatever Linux distributor
+    people see the problem on.  In my opinion, syslogd should be changed to
+    use some other method of communication, or the wrapper function (which
+    appeared to be `daemon' when I looked at it some time ago) or script
+    (which appeared to be `syslog') should catch SIGINT, since it's an
+    expected event, and exit cleanly.
+
+7.  Several people have reported that `dip' (a program for SLIP/PPP
+    on Linux) does not work with bash-2.0 installed as /bin/sh.
+
+    I don't run any Linux boxes myself, and do not have the dip
+    code handy to look at, but the `problem' with bash-2.0, as
+    it has been related to me, is that bash requires the `-p'
+    option to be supplied at invocation if it is to run setuid
+    or setgid. 
+
+    This means, among other things, that setuid or setgid programs
+    which call system(3) (a horrendously bad practice in any case)
+    relinquish their setuid/setgid status in the child that's forked
+    to execute /bin/sh. 
+
+    The following is an *unofficial* patch to bash-2.0 that causes it
+    to not require `-p' to run setuid or setgid if invoked as `sh'.
+    It has been reported to work on Linux.  It will make your system
+    vulnerable to bogus system(3) calls in setuid executables.

+9.  Hints for building under Minix 2.0 (Contributed by Terry R. McConnell,
+    <tmc@barnyard.syr.edu>)
+
+   The version of /bin/sh distributed with Minix is not up to the job of
+   running the configure script. The easiest solution is to swap /bin/sh
+   with /usr/bin/ash. Then use chmem(1) to increase the memory allocated
+   to /bin/sh. The following settings are known to work:
+
+   text         data     bss   stack  memory
+   63552  9440          3304   65536  141832  /bin/sh
+
+   If you have problems with make or yacc it may be worthwhile first to
+   install the GNU versions of these utilities before attempting to build
+   bash. (As of this writing, all of these utilities are available for the
+   i386 as pre-built binaries via anonymous ftp at math.syr.edu in the
+   pub/mcconnell/minix directory. Note that the GNU version of yacc is called
+   bison.)
+
+   Unless you want to see lots of warnings about old-style declarations,
+   do LOCAL_CFLAGS=-wo; export LOCAL_CFLAGS before running configure.
+   (These warnings are harmless, but annoying.)
+
+   configure will insist that you supply a host type. For example, do
+   ./configure --host=i386-pc-minix.
+
+   Minix does not support the system calls required for a proper 
+   implementation of ulimit().  The `ulimit' builtin will not be available.
+
+   Configure will fail to notice that many things like uid_t are indeed
+   typedef'd in <sys/types.h>, because it uses egrep for this purpose
+   and minix has no egrep. You could try making a link /usr/bin/egrep -->
+   /usr/bin/grep. Better is to install the GNU version of grep in
+   /usr/local/bin and make the link /usr/local/bin/egrep -->/usr/local/bin/grep.
+   (These must be hard links, of course, since Minix does not support
+   symbolic links.)
+
+   You will see many warnings of the form:
+   warning: unknown s_type: 98
+   I have no idea what this means, but it doesn't seem to matter.
+
+10. If you do not have /usr/ccs/bin in your PATH when building on SunOS 5.x
+    (Solaris 2), the configure script will be unable to find `ar' and
+    `ranlib' (of course, ranlib is unnecessary).  Make sure your $PATH
+    includes /usr/ccs/bin on SunOS 5.x.  This generally manifests itself
+    with libraries not being built and make reporting errors like
+    `cr: not found' when library construction is attempted.
+
+11. Building a statically-linked bash on Solaris 2.5.x, 2.6, 7, or 8 is
+    complicated.
+
+    It's not possible to build a completely statically-linked binary, since
+    part of the C library depends on dynamic linking.  The following recipe
+    assumes that you're using gcc and the Solaris ld (/usr/ccs/bin/ld) on
+    Solaris 2.5.x or 2.6:
+
+	configure --enable-static-link
+	make STATIC_LD= LOCAL_LIBS='-Wl,-B,dynamic -ldl -Wl,-B,static'
+
+    This should result in a bash binary that depends only on libdl.so:
+
+	thor(2)$ ldd bash
+	        libdl.so.1 =>    /usr/lib/libdl.so.1
+
+    If you're using the Sun C Compiler (Sun WorkShop C Compiler version
+    4.2 was what I used), you should be able to get away with using
+
+	configure --enable-static-link
+	make STATIC_LD=  LOCAL_LIBS='-B dynamic -ldl -B static'
+
+    If you want to completely remove any dependence on /usr, perhaps
+    to put a copy of bash in /sbin and have it available when /usr is
+    not mounted, force the build process to use the shared dl.so library
+    in /etc/lib.
+
+    For gcc, this would be something like
+
+	configure --enable-static-link
+	make STATIC_LD= LOCAL_LIBS='-Wl,-B,dynamic -Wl,-R/etc/lib -ldl -Wl,-B,static'
+
+    For Sun's WS4.2 cc
+
+	configure --enable-static-link
+	make STATIC_LD=  LOCAL_LIBS='-B dynamic -R/etc/lib -ldl -B static'
+
+    seems to work, at least on Solaris 2.5.1:
+
+	thor(2)$ ldd bash
+	        libdl.so.1 =>    /etc/lib/libdl.so.1
+
+    On Solaris 7 (Solaris 8, using the version of gcc on the free software
+    CD-ROM), the following recipe appears to work for gcc:
+
+	configure --enable-static-link
+	make STATIC_LD='-Wl,-Bstatic' LOCAL_LIBS='-Wl,-Bdynamic -Wl,-R/etc/lib -ldl -Wl,-Bstatic'
+
+	thor.ins.cwru.edu(2)$ ldd bash
+	        libdl.so.1 =>    /etc/lib/libdl.so.1
+
+    Make the analogous changes if you are running Sun's C Compiler.
+
+    I have received word that adding -L/etc/lib (or the equivalent
+    -Wl,-L/etc/lib) might also be necessary, in addition to the -R/etc/lib.
+
+    On later versions of Solaris, it may be necessary to add -lnsl before
+    -ldl; statically-linked versions of bash using libnsl are not guaranteed
+    to work correctly on future versions of Solaris.
+
+12. Configuring bash to build it in a cross environment.  Currently only
+    two native versions can be compiled this way, cygwin32 and x86 BeOS.
+    For BeOS, you would configure it like this:
+
+	export RANLIB=i586-beos-ranlib
+	export AR=i586-beos-ar
+	export CC=i586-beos-gcc
+	configure i586-beos
+
+    Similarly for cygwin32.
+
+13. Bash-2.05 has reverted to the bash-2.03 behavior of honoring the current
+    locale setting when processing ranges within pattern matching bracket
+    expressions ([A-Z]).  This is what POSIX.2 and SUSv2 specify.
+
+    The behavior of the matcher in bash-2.05 depends on the current LC_COLLATE
+    setting.  Setting this variable to `C' or `POSIX' will result in the
+    traditional behavior ([A-Z] matches all uppercase ASCII characters).
+    Many other locales, including the en_US locale (the default on many US
+    versions of Linux) collate the upper and lower case letters like this:
+
+	AaBb...Zz
+
+    which means that [A-Z] matches every letter except `z'.
+
+    The portable way to specify upper case letters is [:upper:] instead of
+    A-Z; lower case may be specified as [:lower:] instead of a-z.
+
+    Look at the manual pages for setlocale(3), strcoll(3), and, if it is
+    present, locale(1).  If you have locale(1), you can use it to find
+    your current locale information even if you do not have any of the
+    LC_ variables set.
+
+    My advice is to put
+
+        export LC_COLLATE=C
+
+    into /etc/profile and inspect any shell scripts run from cron for
+    constructs like [A-Z].  This will prevent things like
+
+	rm [A-Z]*
+
+    from removing every file in the current directory except those beginning
+    with `z' and still allow individual users to change the collation order.
+    Users may put the above command into their own profiles as well, of course.
+
+14. Building on Interix (nee OpenNT), which Microsoft bought from Softway
+    Systems and has seemingly abandoned (thanks to Kevin Moore for this item).
+
+	1.  cp cross-build/opennt.cache config.cache
+
+	2.  If desired, edit pathnames.h to set the values of SYS_PROFILE and
+	    DEFAULT_HOSTS_FILE appropriately.
+
+	3.  export CONFIG_SHELL=$INTERIX_ROOT/bin/sh
+
+	4.  ./configure --prefix=$INTERIX_ROOT/usr/local (or wherever you
+	    want it).
+
+	5. make; make install; enjoy
+
+15.  Configure with `CC=xlc' if you don't have gcc on AIX 4.2 and later
+     versions.  `xlc' running in `cc' mode has trouble compiling error.c.
+
+16.  Configure --disable-multibyte on NetBSD versions (1.4 through at least
+     1.6.1) that include wctype.h but do not define wctype_t.
+
+17.  Do NOT use bison-1.75.  It builds a non-working parser.  The most
+     obvious effect is that constructs like "for i; do echo $i; done" don't
+     loop over the positional parameters.
+
+18.  I have received reports that using -O2 with the MIPSpro results in a
+     binary that fails in strange ways.  Using -O1 seems to work.
+
+19.  There is special handling to ensure the shell links against static
+     versions of the included readline and history libraries on Mac OS X;
+     Apple ships inadequate dynamic libreadline and libhistory "replacements"
+     as standard libraries.
+
+20.  If you're on a system like SGI Irix, and you get an error about not
+     being able to refer to a dynamic symbol
+     (ld: non-dynamic relocations refer to dynamic symbol PC), add
+     -DNEED_EXTERN_PC to the LOCAL_CFLAGS variable in lib/readline/Makefile.in
+     and rebuild.

+6.11 Bash POSIX Mode
+====================
+
+Starting Bash with the '--posix' command-line option or executing 'set
+-o posix' while Bash is running will cause Bash to conform more closely
+to the POSIX standard by changing the behavior to match that specified
+by POSIX in areas where the Bash default differs.
+
+When invoked as 'sh', Bash enters POSIX mode after reading the startup
+files.
+
+The following list is what's changed when 'POSIX mode' is in effect:
+
+  1. Bash ensures that the 'POSIXLY_CORRECT' variable is set.
+
+  2. When a command in the hash table no longer exists, Bash will
+     re-search '$PATH' to find the new location.  This is also available
+     with 'shopt -s checkhash'.
+
+  3. Bash will not insert a command without the execute bit set into the
+     command hash table, even if it returns it as a (last-ditch) result
+     from a '$PATH' search.
+
+  4. The message printed by the job control code and builtins when a job
+     exits with a non-zero status is 'Done(status)'.
+
+  5. The message printed by the job control code and builtins when a job
+     is stopped is 'Stopped(SIGNAME)', where SIGNAME is, for example,
+     'SIGTSTP'.
+
+  6. Alias expansion is always enabled, even in non-interactive shells.
+
+  7. Reserved words appearing in a context where reserved words are
+     recognized do not undergo alias expansion.
+
+  8. Alias expansion is performed when initially parsing a command
+     substitution.  The default mode generally defers it, when enabled,
+     until the command substitution is executed.  This means that
+     command substitution will not expand aliases that are defined after
+     the command substitution is initially parsed (e.g., as part of a
+     function definition).
+
+  9. The POSIX 'PS1' and 'PS2' expansions of '!' to the history number
+     and '!!' to '!' are enabled, and parameter expansion is performed
+     on the values of 'PS1' and 'PS2' regardless of the setting of the
+     'promptvars' option.
+
+  10. The POSIX startup files are executed ('$ENV') rather than the
+     normal Bash files.
+
+  11. Tilde expansion is only performed on assignments preceding a
+     command name, rather than on all assignment statements on the line.
+
+  12. The default history file is '~/.sh_history' (this is the default
+     value of '$HISTFILE').
+
+  13. Redirection operators do not perform filename expansion on the
+     word in the redirection unless the shell is interactive.
+
+  14. Redirection operators do not perform word splitting on the word in
+     the redirection.
+
+  15. Function names must be valid shell 'name's.  That is, they may not
+     contain characters other than letters, digits, and underscores, and
+     may not start with a digit.  Declaring a function with an invalid
+     name causes a fatal syntax error in non-interactive shells.
+
+  16. Function names may not be the same as one of the POSIX special
+     builtins.
+
+  17. POSIX special builtins are found before shell functions during
+     command lookup.
+
+  18. When printing shell function definitions (e.g., by 'type'), Bash
+     does not print the 'function' keyword.
+
+  19. Literal tildes that appear as the first character in elements of
+     the 'PATH' variable are not expanded as described above under *note
+     Tilde Expansion::.
+
+  20. The 'time' reserved word may be used by itself as a command.  When
+     used in this way, it displays timing statistics for the shell and
+     its completed children.  The 'TIMEFORMAT' variable controls the
+     format of the timing information.
+
+  21. When parsing and expanding a ${...} expansion that appears within
+     double quotes, single quotes are no longer special and cannot be
+     used to quote a closing brace or other special character, unless
+     the operator is one of those defined to perform pattern removal.
+     In this case, they do not have to appear as matched pairs.
+
+  22. The parser does not recognize 'time' as a reserved word if the
+     next token begins with a '-'.
+
+  23. The '!' character does not introduce history expansion within a
+     double-quoted string, even if the 'histexpand' option is enabled.
+
+  24. If a POSIX special builtin returns an error status, a
+     non-interactive shell exits.  The fatal errors are those listed in
+     the POSIX standard, and include things like passing incorrect
+     options, redirection errors, variable assignment errors for
+     assignments preceding the command name, and so on.
+
+  25. A non-interactive shell exits with an error status if a variable
+     assignment error occurs when no command name follows the assignment
+     statements.  A variable assignment error occurs, for example, when
+     trying to assign a value to a readonly variable.
+
+  26. A non-interactive shell exits with an error status if a variable
+     assignment error occurs in an assignment statement preceding a
+     special builtin, but not with any other simple command.  For any
+     other simple command, the shell aborts execution of that command,
+     and execution continues at the top level ("the shell shall not
+     perform any further processing of the command in which the error
+     occurred").
+
+  27. A non-interactive shell exits with an error status if the
+     iteration variable in a 'for' statement or the selection variable
+     in a 'select' statement is a readonly variable.
+
+  28. Non-interactive shells exit if FILENAME in '.'  FILENAME is not
+     found.
+
+  29. Non-interactive shells exit if a syntax error in an arithmetic
+     expansion results in an invalid expression.
+
+  30. Non-interactive shells exit if a parameter expansion error occurs.
+
+  31. Non-interactive shells exit if there is a syntax error in a script
+     read with the '.' or 'source' builtins, or in a string processed by
+     the 'eval' builtin.
+
+  32. While variable indirection is available, it may not be applied to
+     the '#' and '?' special parameters.
+
+  33. Expanding the '*' special parameter in a pattern context where the
+     expansion is double-quoted does not treat the '$*' as if it were
+     double-quoted.
+
+  34. Assignment statements preceding POSIX special builtins persist in
+     the shell environment after the builtin completes.
+
+  35. The 'command' builtin does not prevent builtins that take
+     assignment statements as arguments from expanding them as
+     assignment statements; when not in POSIX mode, assignment builtins
+     lose their assignment statement expansion properties when preceded
+     by 'command'.
+
+  36. The 'bg' builtin uses the required format to describe each job
+     placed in the background, which does not include an indication of
+     whether the job is the current or previous job.
+
+  37. The output of 'kill -l' prints all the signal names on a single
+     line, separated by spaces, without the 'SIG' prefix.
+
+  38. The 'kill' builtin does not accept signal names with a 'SIG'
+     prefix.
+
+  39. The 'export' and 'readonly' builtin commands display their output
+     in the format required by POSIX.
+
+  40. The 'trap' builtin displays signal names without the leading
+     'SIG'.
+
+  41. The 'trap' builtin doesn't check the first argument for a possible
+     signal specification and revert the signal handling to the original
+     disposition if it is, unless that argument consists solely of
+     digits and is a valid signal number.  If users want to reset the
+     handler for a given signal to the original disposition, they should
+     use '-' as the first argument.
+
+  42. 'trap -p' displays signals whose dispositions are set to SIG_DFL
+     and those that were ignored when the shell started.
+
+  43. The '.' and 'source' builtins do not search the current directory
+     for the filename argument if it is not found by searching 'PATH'.
+
+  44. Enabling POSIX mode has the effect of setting the
+     'inherit_errexit' option, so subshells spawned to execute command
+     substitutions inherit the value of the '-e' option from the parent
+     shell.  When the 'inherit_errexit' option is not enabled, Bash
+     clears the '-e' option in such subshells.
+
+  45. Enabling POSIX mode has the effect of setting the 'shift_verbose'
+     option, so numeric arguments to 'shift' that exceed the number of
+     positional parameters will result in an error message.
+
+  46. When the 'alias' builtin displays alias definitions, it does not
+     display them with a leading 'alias ' unless the '-p' option is
+     supplied.
+
+  47. When the 'set' builtin is invoked without options, it does not
+     display shell function names and definitions.
+
+  48. When the 'set' builtin is invoked without options, it displays
+     variable values without quotes, unless they contain shell
+     metacharacters, even if the result contains nonprinting characters.
+
+  49. When the 'cd' builtin is invoked in logical mode, and the pathname
+     constructed from '$PWD' and the directory name supplied as an
+     argument does not refer to an existing directory, 'cd' will fail
+     instead of falling back to physical mode.
+
+  50. When the 'cd' builtin cannot change a directory because the length
+     of the pathname constructed from '$PWD' and the directory name
+     supplied as an argument exceeds 'PATH_MAX' when all symbolic links
+     are expanded, 'cd' will fail instead of attempting to use only the
+     supplied directory name.
+
+  51. The 'pwd' builtin verifies that the value it prints is the same as
+     the current directory, even if it is not asked to check the file
+     system with the '-P' option.
+
+  52. When listing the history, the 'fc' builtin does not include an
+     indication of whether or not a history entry has been modified.
+
+  53. The default editor used by 'fc' is 'ed'.
+
+  54. The 'type' and 'command' builtins will not report a non-executable
+     file as having been found, though the shell will attempt to execute
+     such a file if it is the only so-named file found in '$PATH'.
+
+  55. The 'vi' editing mode will invoke the 'vi' editor directly when
+     the 'v' command is run, instead of checking '$VISUAL' and
+     '$EDITOR'.
+
+  56. When the 'xpg_echo' option is enabled, Bash does not attempt to
+     interpret any arguments to 'echo' as options.  Each argument is
+     displayed, after escape characters are converted.
+
+  57. The 'ulimit' builtin uses a block size of 512 bytes for the '-c'
+     and '-f' options.
+
+  58. The arrival of 'SIGCHLD' when a trap is set on 'SIGCHLD' does not
+     interrupt the 'wait' builtin and cause it to return immediately.
+     The trap command is run once for each child that exits.
+
+  59. The 'read' builtin may be interrupted by a signal for which a trap
+     has been set.  If Bash receives a trapped signal while executing
+     'read', the trap handler executes and 'read' returns an exit status
+     greater than 128.
+
+  60. The 'printf' builtin uses 'double' (via 'strtod') to convert
+     arguments corresponding to floating point conversion specifiers,
+     instead of 'long double' if it's available.  The 'L' length
+     modifier forces 'printf' to use 'long double' if it's available.
+
+  61. Bash removes an exited background process's status from the list
+     of such statuses after the 'wait' builtin is used to obtain it.
+
+There is other POSIX behavior that Bash does not implement by default
+even when in POSIX mode.  Specifically:
+
+  1. The 'fc' builtin checks '$EDITOR' as a program to edit history
+     entries if 'FCEDIT' is unset, rather than defaulting directly to
+     'ed'.  'fc' uses 'ed' if 'EDITOR' is unset.
+
+  2. As noted above, Bash requires the 'xpg_echo' option to be enabled
+     for the 'echo' builtin to be fully conformant.
+
+Bash can be configured to be POSIX-conformant by default, by specifying
+the '--enable-strict-posix-default' to 'configure' when building (*note
+Optional Features::).

+6.10 The Restricted Shell
+=========================
+
+If Bash is started with the name 'rbash', or the '--restricted' or '-r'
+option is supplied at invocation, the shell becomes restricted.  A
+restricted shell is used to set up an environment more controlled than
+the standard shell.  A restricted shell behaves identically to 'bash'
+with the exception that the following are disallowed or not performed:
+
+   * Changing directories with the 'cd' builtin.
+   * Setting or unsetting the values of the 'SHELL', 'PATH', 'HISTFILE',
+     'ENV', or 'BASH_ENV' variables.
+   * Specifying command names containing slashes.
+   * Specifying a filename containing a slash as an argument to the '.'
+     builtin command.
+   * Specifying a filename containing a slash as an argument to the
+     'history' builtin command.
+   * Specifying a filename containing a slash as an argument to the '-p'
+     option to the 'hash' builtin command.
+   * Importing function definitions from the shell environment at
+     startup.
+   * Parsing the value of 'SHELLOPTS' from the shell environment at
+     startup.
+   * Redirecting output using the '>', '>|', '<>', '>&', '&>', and '>>'
+     redirection operators.
+   * Using the 'exec' builtin to replace the shell with another command.
+   * Adding or deleting builtin commands with the '-f' and '-d' options
+     to the 'enable' builtin.
+   * Using the 'enable' builtin command to enable disabled shell
+     builtins.
+   * Specifying the '-p' option to the 'command' builtin.
+   * Turning off restricted mode with 'set +r' or 'shopt -u
+     restricted_shell'.
+
+These restrictions are enforced after any startup files are read.
+
+When a command that is found to be a shell script is executed (*note
+Shell Scripts::), 'rbash' turns off any restrictions in the shell
+spawned to execute the script.
+
+The restricted shell mode is only one component of a useful restricted
+environment.  It should be accompanied by setting 'PATH' to a value that
+allows execution of only a few verified commands (commands that allow
+shell escapes are particularly vulnerable), changing the current
+directory to a non-writable directory other than '$HOME' after login,
+not allowing the restricted shell to execute shell scripts, and cleaning
+the environment of variables that cause some commands to modify their
+behavior (e.g., 'VISUAL' or 'PAGER').
+
+Modern systems provide more secure ways to implement a restricted
+environment, such as 'jails', 'zones', or 'containers'.

+Introduction
+============
+
+This is GNU Bash, version 5.2. Bash is the GNU Project's Bourne
+Again SHell, a complete implementation of the POSIX shell spec,
+but also with interactive command line editing, job control on
+architectures that support it, csh-like features such as history
+substitution and brace expansion, and a slew of other features. 
+For more information on the features of Bash that are new to this
+type of shell, see the file `doc/bashref.texi'.  There is also a
+large Unix-style man page.  The man page is the definitive description
+of the shell's features. 
+
+See the file POSIX for a discussion of how the Bash defaults differ
+from the POSIX spec and a description of the Bash `posix mode'.
+
+There are some user-visible incompatibilities between this version
+of Bash and previous widely-distributed versions, bash-4.4, bash-5.0,
+and bash-5.1. For details, see the file COMPAT.  The NEWS file tersely
+lists features that are new in this release. 
+
+Bash is free software, distributed under the terms of the [GNU] General
+Public License as published by the Free Software Foundation,
+version 3 of the License (or any later version).  For more information,
+see the file COPYING. 
+
+A number of frequently-asked questions are answered in the file
+`doc/FAQ'. (That file is no longer updated.)
+
+To compile Bash, type `./configure', then `make'.  Bash auto-configures
+the build process, so no further intervention should be necessary.  Bash
+builds with `gcc' by default if it is available.  If you want to use `cc'
+instead, type
+
+	CC=cc ./configure
+
+if you are using a Bourne-style shell.  If you are not, the following
+may work:
+
+	env CC=cc ./configure
+
+Read the file INSTALL in this directory for more information about how
+to customize and control the build process.  The file NOTES contains
+platform-specific installation and configuration information.
+
+If you are a csh user and wish to convert your csh aliases to Bash
+aliases, you may wish to use the script `examples/misc/alias-conv.sh'
+as a starting point.  The script `examples/misc/cshtobash' is a
+more ambitious script that attempts to do a more complete job.
+
+Reporting Bugs
+==============
+
+Bug reports for bash should be sent to:
+
+	bug-bash@gnu.org
+
+using the `bashbug' program that is built and installed at the same
+time as bash.
+
+The discussion list `bug-bash@gnu.org' often contains information
+about new ports of Bash, or discussions of new features or behavior
+changes that people would like.  This mailing list is also available
+as a usenet newsgroup: gnu.bash.bug. 
+
+When you send a bug report, please use the `bashbug' program that is
+built at the same time as bash.  If bash fails to build, try building
+bashbug directly with `make bashbug'.  If you cannot build `bashbug',
+please send mail to bug-bash@gnu.org with the following information:
+
+	* the version number and release status of Bash (e.g., 2.05a-release)
+	* the machine and OS that it is running on (you may run
+	  `bashversion -l' from the bash build directory for this information)
+	* a list of the compilation flags or the contents of `config.h', if
+	  appropriate
+	* a description of the bug
+	* a recipe for recreating the bug reliably
+	* a fix for the bug if you have one!
+
+The `bashbug' program includes much of this automatically.
+
+Questions and requests for help with bash and bash programming may be
+sent to the help-bash@gnu.org mailing list.
+
+If you would like to contact the Bash maintainers directly, send mail
+to bash-maintainers@gnu.org.
+
+While the Bash maintainers do not promise to fix all bugs, we would
+like this shell to be the best that we can make it.
+
+Other Packages
+==============
+
+This distribution includes, in examples/bash-completion, a recent version
+of the `bash-completion' package, which provides programmable completions
+for a number of commands. It's available as a package in many distributions,
+and that is the first place from which to obtain it.
+
+The latest version of bash-completion is always available from
+https://github.com/scop/bash-completion.
+
+If it's not a package from your vendor, you may install the included version.
+
+Enjoy!

+$FUNCTION alias_builtin

+$SHORT_DOC alias [-p] [name[=value] ... ]
+Define or display aliases.
+
+Without arguments, `alias' prints the list of aliases in the reusable
+form `alias NAME=VALUE' on standard output.
+
+Otherwise, an alias is defined for each NAME whose VALUE is given.
+A trailing space in VALUE causes the next word to be checked for
+alias substitution when the alias is expanded.
+
+Options:
+  -p	print all defined aliases in a reusable format
+
+Exit Status:
+alias returns true unless a NAME is supplied for which no alias has been
+defined.

+$SHORT_DOC bind [-lpsvPSVX] [-m keymap] [-f filename] [-q name] [-u name] [-r keyseq] [-x keyseq:shell-command] [keyseq:readline-function or readline-command]
+Set Readline key bindings and variables.
+
+Bind a key sequence to a Readline function or a macro, or set a
+Readline variable.  The non-option argument syntax is equivalent to
+that found in ~/.inputrc, but must be passed as a single argument:
+e.g., bind '"\C-x\C-r": re-read-init-file'.
+
+Options:
+  -m  keymap         Use KEYMAP as the keymap for the duration of this
+                     command.  Acceptable keymap names are emacs,
+                     emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move,
+                     vi-command, and vi-insert.
+  -l                 List names of functions.
+  -P                 List function names and bindings.
+  -p                 List functions and bindings in a form that can be
+                     reused as input.
+  -S                 List key sequences that invoke macros and their values
+  -s                 List key sequences that invoke macros and their values
+                     in a form that can be reused as input.
+  -V                 List variable names and values
+  -v                 List variable names and values in a form that can
+                     be reused as input.
+  -q  function-name  Query about which keys invoke the named function.
+  -u  function-name  Unbind all keys which are bound to the named function.
+  -r  keyseq         Remove the binding for KEYSEQ.
+  -f  filename       Read key bindings from FILENAME.
+  -x  keyseq:shell-command	Cause SHELL-COMMAND to be executed when
+				KEYSEQ is entered.
+  -X                 List key sequences bound with -x and associated commands
+                     in a form that can be reused as input.
+
+Exit Status:
+bind returns 0 unless an unrecognized option is given or an error occurs.

+$BUILTIN cd
+$FUNCTION cd_builtin
+$SHORT_DOC cd [-L|[-P [-e]] [-@]] [dir]
+Change the shell working directory.
+
+Change the current directory to DIR.  The default DIR is the value of the
+HOME shell variable. If DIR is "-", it is converted to $OLDPWD.
+
+The variable CDPATH defines the search path for the directory containing
+DIR.  Alternative directory names in CDPATH are separated by a colon (:).
+A null directory name is the same as the current directory.  If DIR begins
+with a slash (/), then CDPATH is not used.
+
+If the directory is not found, and the shell option `cdable_vars' is set,
+the word is assumed to be  a variable name.  If that variable has a value,
+its value is used for DIR.
+
+Options:
+  -L	force symbolic links to be followed: resolve symbolic
+		links in DIR after processing instances of `..'
+  -P	use the physical directory structure without following
+		symbolic links: resolve symbolic links in DIR before
+		processing instances of `..'
+  -e	if the -P option is supplied, and the current working
+		directory cannot be determined successfully, exit with
+		a non-zero status
+#if defined (O_XATTR)
+  -@	on systems that support it, present a file with extended
+		attributes as a directory containing the file attributes
+#endif
+
+The default is to follow symbolic links, as if `-L' were specified.
+`..' is processed by removing the immediately previous pathname component
+back to a slash or the beginning of DIR.
+
+Exit Status:
+Returns 0 if the directory is changed, and if $PWD is set successfully when
+-P is used; non-zero otherwise.

+Specify how arguments are to be completed by Readline.
+
+For each NAME, specify how arguments are to be completed.  If no options
+are supplied, existing completion specifications are printed in a way that
+allows them to be reused as input.
+
+Options:
+  -p	print existing completion specifications in a reusable format
+  -r	remove a completion specification for each NAME, or, if no
+		NAMEs are supplied, all completion specifications
+  -D	apply the completions and actions as the default for commands
+		without any specific completion defined
+  -E	apply the completions and actions to "empty" commands --
+		completion attempted on a blank line
+  -I	apply the completions and actions to the initial (usually the
+		command) word
+
+When completion is attempted, the actions are applied in the order the
+uppercase-letter options are listed above. If multiple options are supplied,
+the -D option takes precedence over -E, and both take precedence over -I.
+
+Exit Status:
+Returns success unless an invalid option is supplied or an error occurs.

+Modify the completion options for each NAME, or, if no NAMEs are supplied,

+Options:

+Arguments:
+
+Each NAME refers to a command for which a completion specification must

+are supplied, compopt must be called by a function currently generating
+completions, and the options for that currently-executing completion

+Enables and disables builtin shell commands.  Disabling allows you to
+execute a disk command which has the same name as a shell builtin
+without using a full pathname.
+
+Options:
+  -a	print a list of builtins showing whether or not each is enabled
+  -n	disable each NAME or display a list of disabled builtins
+  -p	print the list of builtins in a reusable format
+  -s	print only the names of Posix `special' builtins
+
+Options controlling dynamic loading:
+  -f	Load builtin NAME from shared object FILENAME
+  -d	Remove a builtin loaded with -f
+
+Without options, each NAME is enabled.
+
+To use the `test' found in $PATH instead of the shell builtin
+version, type `enable -n test'.
+
+Exit Status:
+Returns success unless NAME is not a shell builtin or an error occurs.

+$FUNCTION exec_builtin
+$SHORT_DOC exec [-cl] [-a name] [command [argument ...]] [redirection ...]
+Replace the shell with the given command.
+
+Execute COMMAND, replacing this shell with the specified program.
+ARGUMENTS become the arguments to COMMAND.  If COMMAND is not specified,
+any redirections take effect in the current shell.
+
+Options:
+  -a name	pass NAME as the zeroth argument to COMMAND
+  -c	execute COMMAND with an empty environment
+  -l	place a dash in the zeroth argument to COMMAND
+
+If the command cannot be executed, a non-interactive shell exits, unless
+the shell option `execfail' is set.
+
+Exit Status:
+Returns success unless COMMAND is not found or a redirection error occurs.

+$DEPENDS_ON HISTORY
+$SHORT_DOC fc [-e ename] [-lnr] [first] [last] or fc -s [pat=rep] [command]
+Display or execute commands from the history list.
+
+fc is used to list or edit and re-execute commands from the history list.
+FIRST and LAST can be numbers specifying the range, or FIRST can be a
+string, which means the most recent command beginning with that
+string.
+
+Options:
+  -e ENAME	select which editor to use.  Default is FCEDIT, then EDITOR,
+		then vi
+  -l 	list lines instead of editing
+  -n	omit line numbers when listing
+  -r	reverse the order of the lines (newest listed first)
+
+With the `fc -s [pat=rep ...] [command]' format, COMMAND is
+re-executed after the substitution OLD=NEW is performed.
+
+A useful alias to use with this is r='fc -s', so that typing `r cc'
+runs the last command beginning with `cc' and typing `r' re-executes
+the last command.
+
+Exit Status:
+Returns success or status of executed command; non-zero if an error occurs.

+
+$BUILTIN getopts
+$FUNCTION getopts_builtin
+$SHORT_DOC getopts optstring name [arg ...]
+Parse option arguments.
+
+Getopts is used by shell procedures to parse positional parameters
+as options.
+
+OPTSTRING contains the option letters to be recognized; if a letter
+is followed by a colon, the option is expected to have an argument,
+which should be separated from it by white space.
+
+Each time it is invoked, getopts will place the next option in the
+shell variable $name, initializing name if it does not exist, and
+the index of the next argument to be processed into the shell
+variable OPTIND.  OPTIND is initialized to 1 each time the shell or
+a shell script is invoked.  When an option requires an argument,
+getopts places that argument into the shell variable OPTARG.
+
+getopts reports errors in one of two ways.  If the first character
+of OPTSTRING is a colon, getopts uses silent error reporting.  In
+this mode, no error messages are printed.  If an invalid option is
+seen, getopts places the option character found into OPTARG.  If a
+required argument is not found, getopts places a ':' into NAME and
+sets OPTARG to the option character found.  If getopts is not in
+silent mode, and an invalid option is seen, getopts places '?' into
+NAME and unsets OPTARG.  If a required argument is not found, a '?'
+is placed in NAME, OPTARG is unset, and a diagnostic message is
+printed.
+
+If the shell variable OPTERR has the value 0, getopts disables the
+printing of error messages, even if the first character of
+OPTSTRING is not a colon.  OPTERR has the value 1 by default.
+
+Getopts normally parses the positional parameters, but if arguments
+are supplied as ARG values, they are parsed instead.
+
+Exit Status:
+Returns success if an option is found; fails if the end of options is
+encountered or an error occurs.

+$BUILTIN history
+$FUNCTION history_builtin
+$DEPENDS_ON HISTORY
+$SHORT_DOC history [-c] [-d offset] [n] or history -anrw [filename] or history -ps arg [arg...]
+Display or manipulate the history list.
+
+Display the history list with line numbers, prefixing each modified
+entry with a `*'.  An argument of N lists only the last N entries.
+
+Options:
+  -c	clear the history list by deleting all of the entries
+  -d offset	delete the history entry at position OFFSET. Negative
+		offsets count back from the end of the history list
+
+  -a	append history lines from this session to the history file
+  -n	read all history lines not already read from the history file
+		and append them to the history list
+  -r	read the history file and append the contents to the history
+		list
+  -w	write the current history to the history file
+
+  -p	perform history expansion on each ARG and display the result
+		without storing it in the history list
+  -s	append the ARGs to the history list as a single entry
+
+If FILENAME is given, it is used as the history file.  Otherwise,
+if HISTFILE has a value, that is used, else ~/.bash_history.
+
+If the HISTTIMEFORMAT variable is set and not null, its value is used
+as a format string for strftime(3) to print the time stamp associated
+with each displayed history entry.  No time stamps are printed otherwise.
+
+Exit Status:
+Returns success unless an invalid option is given or an error occurs.

+Send a signal to a job.
+
+Send the processes identified by PID or JOBSPEC the signal named by
+SIGSPEC or SIGNUM.  If neither SIGSPEC nor SIGNUM is present, then
+SIGTERM is assumed.
+
+Options:
+  -s sig	SIG is a signal name

+Kill is a shell builtin for two reasons: it allows job IDs to be used
+instead of process IDs, and allows processes to be killed if the limit
+on processes that you can create is reached.

+Exit Status:
+Returns success unless an invalid option is given or an error occurs.

+
+$BUILTIN mapfile
+$FUNCTION mapfile_builtin
+$SHORT_DOC mapfile [-d delim] [-n count] [-O origin] [-s count] [-t] [-u fd] [-C callback] [-c quantum] [array]
+Read lines from the standard input into an indexed array variable.
+
+Read lines from the standard input into the indexed array variable ARRAY, or
+from file descriptor FD if the -u option is supplied.  The variable MAPFILE
+is the default ARRAY.
+
+Options:
+  -d delim	Use DELIM to terminate lines, instead of newline
+  -n count	Copy at most COUNT lines.  If COUNT is 0, all lines are copied
+  -O origin	Begin assigning to ARRAY at index ORIGIN.  The default index is 0
+  -s count	Discard the first COUNT lines read
+  -t	Remove a trailing DELIM from each line read (default newline)
+  -u fd	Read lines from file descriptor FD instead of the standard input
+  -C callback	Evaluate CALLBACK each time QUANTUM lines are read
+  -c quantum	Specify the number of lines read between each call to
+			CALLBACK
+
+Arguments:
+  ARRAY	Array variable name to use for file data
+
+If -C is supplied without -c, the default quantum is 5000.  When
+CALLBACK is evaluated, it is supplied the index of the next array
+element to be assigned and the line to be assigned to that element
+as additional arguments.
+
+If not supplied with an explicit origin, mapfile will clear ARRAY before
+assigning to it.
+
+Exit Status:
+Returns success unless an invalid option is given or ARRAY is readonly or
+not an indexed array.

+  %b	expand backslash escape sequences in the corresponding argument
+  %q	quote the argument in a way that can be reused as shell input
+  %Q	like %q, but apply any precision to the unquoted argument before
+		quoting
+  %(fmt)T	output the date-time string resulting from using FMT as a format
+	        string for strftime(3)
+
+The format is re-used as necessary to consume all of the arguments.  If
+there are fewer arguments than the format requires,  extra format
+specifications behave as if a zero value or null string, as appropriate,
+had been supplied.
+
+Exit Status:
+Returns success unless an invalid option is given or a write or assignment
+error occurs.

+
+$BUILTIN pushd
+$FUNCTION pushd_builtin
+$DEPENDS_ON PUSHD_AND_POPD
+$SHORT_DOC pushd [-n] [+N | -N | dir]
+Add directories to stack.
+
+Adds a directory to the top of the directory stack, or rotates
+the stack, making the new top of the stack the current working
+directory.  With no arguments, exchanges the top two directories.
+
+Options:
+  -n	Suppresses the normal change of directory when adding
+		directories to the stack, so only the stack is manipulated.
+
+Arguments:
+  +N	Rotates the stack so that the Nth directory (counting
+		from the left of the list shown by `dirs', starting with
+		zero) is at the top.
+
+  -N	Rotates the stack so that the Nth directory (counting
+		from the right of the list shown by `dirs', starting with
+		zero) is at the top.
+
+  dir	Adds DIR to the directory stack at the top, making it the
+		new current working directory.
+
+The `dirs' builtin displays the directory stack.
+
+Exit Status:
+Returns success unless an invalid argument is supplied or the directory
+change fails.
+$END
+
+$BUILTIN popd
+$FUNCTION popd_builtin
+$DEPENDS_ON PUSHD_AND_POPD
+$SHORT_DOC popd [-n] [+N | -N]
+Remove directories from stack.
+
+Removes entries from the directory stack.  With no arguments, removes
+the top directory from the stack, and changes to the new top directory.
+
+Options:
+  -n	Suppresses the normal change of directory when removing
+		directories from the stack, so only the stack is manipulated.
+
+Arguments:
+  +N	Removes the Nth entry counting from the left of the list
+		shown by `dirs', starting with zero.  For example: `popd +0'
+		removes the first directory, `popd +1' the second.
+
+  -N	Removes the Nth entry counting from the right of the list
+		shown by `dirs', starting with zero.  For example: `popd -0'
+		removes the last directory, `popd -1' the next to last.
+
+The `dirs' builtin displays the directory stack.
+
+Exit Status:
+Returns success unless an invalid argument is supplied or the directory
+change fails.
+$END
+
+$BUILTIN dirs
+$FUNCTION dirs_builtin
+$DEPENDS_ON PUSHD_AND_POPD
+$SHORT_DOC dirs [-clpv] [+N] [-N]
+Display directory stack.
+
+Display the list of currently remembered directories.  Directories
+find their way onto the list with the `pushd' command; you can get
+back up through the list with the `popd' command.
+
+Options:
+  -c	clear the directory stack by deleting all of the elements
+  -l	do not print tilde-prefixed versions of directories relative
+		to your home directory
+  -p	print the directory stack with one entry per line
+  -v	print the directory stack with one entry per line prefixed
+		with its position in the stack
+
+Arguments:
+  +N	Displays the Nth entry counting from the left of the list
+		shown by dirs when invoked without options, starting with
+		zero.
+
+  -N	Displays the Nth entry counting from the right of the list
+		shown by dirs when invoked without options, starting with
+		zero.
+
+Exit Status:
+Returns success unless an invalid option is supplied or an error occurs.

+$FUNCTION read_builtin
+$SHORT_DOC read [-ers] [-a array] [-d delim] [-i text] [-n nchars] [-N nchars] [-p prompt] [-t timeout] [-u fd] [name ...]
+Read a line from the standard input and split it into fields.
+
+Reads a single line from the standard input, or from file descriptor FD
+if the -u option is supplied.  The line is split into fields as with word
+splitting, and the first word is assigned to the first NAME, the second
+word to the second NAME, and so on, with any leftover words assigned to
+the last NAME.  Only the characters found in $IFS are recognized as word
+delimiters. By default, the backslash character escapes delimiter characters
+and newline.
+
+If no NAMEs are supplied, the line read is stored in the REPLY variable.
+
+Options:
+  -a array	assign the words read to sequential indices of the array
+		variable ARRAY, starting at zero
+  -d delim	continue until the first character of DELIM is read, rather
+		than newline
+  -e	use Readline to obtain the line
+  -i text	use TEXT as the initial text for Readline
+  -n nchars	return after reading NCHARS characters rather than waiting
+		for a newline, but honor a delimiter if fewer than
+		NCHARS characters are read before the delimiter
+  -N nchars	return only after reading exactly NCHARS characters, unless
+		EOF is encountered or read times out, ignoring any
+		delimiter
+  -p prompt	output the string PROMPT without a trailing newline before
+		attempting to read
+  -r	do not allow backslashes to escape any characters
+  -s	do not echo input coming from a terminal
+  -t timeout	time out and return failure if a complete line of
+		input is not read within TIMEOUT seconds.  The value of the
+		TMOUT variable is the default timeout.  TIMEOUT may be a
+		fractional number.  If TIMEOUT is 0, read returns
+		immediately, without trying to read any data, returning
+		success only if input is available on the specified
+		file descriptor.  The exit status is greater than 128
+		if the timeout is exceeded
+  -u fd	read from file descriptor FD instead of the standard input
+
+Exit Status:
+The return code is zero, unless end-of-file is encountered, read times out
+(in which case it's greater than 128), a variable assignment error occurs,
+or an invalid file descriptor is supplied as the argument to -u.

+$BUILTIN for
+$SHORT_DOC for NAME [in WORDS ... ] ; do COMMANDS; done
+Execute commands for each member in a list.
+
+The `for' loop executes a sequence of commands for each member in a
+list of items.  If `in WORDS ...;' is not present, then `in "$@"' is
+assumed.  For each element in WORDS, NAME is set to that element, and
+the COMMANDS are executed.
+
+Exit Status:
+Returns the status of the last command executed.
+$END
+
+$BUILTIN for ((
+$DOCNAME arith_for
+$SHORT_DOC for (( exp1; exp2; exp3 )); do COMMANDS; done
+Arithmetic for loop.
+
+Equivalent to
+	(( EXP1 ))
+	while (( EXP2 )); do
+		COMMANDS
+		(( EXP3 ))
+	done
+EXP1, EXP2, and EXP3 are arithmetic expressions.  If any expression is
+omitted, it behaves as if it evaluates to 1.
+
+Exit Status:
+Returns the status of the last command executed.
+$END
+
+$BUILTIN select
+$SHORT_DOC select NAME [in WORDS ... ;] do COMMANDS; done
+Select words from a list and execute commands.
+
+The WORDS are expanded, generating a list of words.  The
+set of expanded words is printed on the standard error, each
+preceded by a number.  If `in WORDS' is not present, `in "$@"'
+is assumed.  The PS3 prompt is then displayed and a line read
+from the standard input.  If the line consists of the number
+corresponding to one of the displayed words, then NAME is set
+to that word.  If the line is empty, WORDS and the prompt are
+redisplayed.  If EOF is read, the command completes.  Any other
+value read causes NAME to be set to null.  The line read is saved
+in the variable REPLY.  COMMANDS are executed after each selection
+until a break command is executed.
+
+Exit Status:
+Returns the status of the last command executed.
+$END
+
+$BUILTIN time
+$SHORT_DOC time [-p] pipeline
+Report time consumed by pipeline's execution.
+
+Execute PIPELINE and print a summary of the real time, user CPU time,
+and system CPU time spent executing PIPELINE when it terminates.
+
+Options:
+  -p	print the timing summary in the portable Posix format
+
+The value of the TIMEFORMAT variable is used as the output format.
+
+Exit Status:
+The return status is the return status of PIPELINE.
+$END
+
+$BUILTIN case
+$SHORT_DOC case WORD in [PATTERN [| PATTERN]...) COMMANDS ;;]... esac
+Execute commands based on pattern matching.
+
+Selectively execute COMMANDS based upon WORD matching PATTERN.  The
+`|' is used to separate multiple patterns.
+
+Exit Status:
+Returns the status of the last command executed.
+$END
+
+$BUILTIN if
+$SHORT_DOC if COMMANDS; then COMMANDS; [ elif COMMANDS; then COMMANDS; ]... [ else COMMANDS; ] fi
+Execute commands based on conditional.
+
+The `if COMMANDS' list is executed.  If its exit status is zero, then the
+`then COMMANDS' list is executed.  Otherwise, each `elif COMMANDS' list is
+executed in turn, and if its exit status is zero, the corresponding
+`then COMMANDS' list is executed and the if command completes.  Otherwise,
+the `else COMMANDS' list is executed, if present.  The exit status of the
+entire construct is the exit status of the last command executed, or zero
+if no condition tested true.
+
+Exit Status:
+Returns the status of the last command executed.
+$END
+
+$BUILTIN while
+$SHORT_DOC while COMMANDS; do COMMANDS-2; done
+Execute commands as long as a test succeeds.
+
+Expand and execute COMMANDS-2 as long as the final command in COMMANDS has
+an exit status of zero.
+
+Exit Status:
+Returns the status of the last command executed.
+$END
+
+$BUILTIN until
+$SHORT_DOC until COMMANDS; do COMMANDS-2; done
+Execute commands as long as a test does not succeed.
+
+Expand and execute COMMANDS-2 as long as the final command in COMMANDS has
+an exit status which is not zero.
+
+Exit Status:
+Returns the status of the last command executed.
+$END
+
+$BUILTIN coproc
+$SHORT_DOC coproc [NAME] command [redirections]
+Create a coprocess named NAME.
+
+Execute COMMAND asynchronously, with the standard output and standard
+input of the command connected via a pipe to file descriptors assigned
+to indices 0 and 1 of an array variable NAME in the executing shell.
+The default NAME is "COPROC".
+
+Exit Status:
+The coproc command returns an exit status of 0.
+$END
+
+$BUILTIN function
+$SHORT_DOC function name { COMMANDS ; } or name () { COMMANDS ; }
+Define shell function.
+
+Create a shell function named NAME.  When invoked as a simple command,
+NAME runs COMMANDs in the calling shell's context.  When NAME is invoked,
+the arguments are passed to the function as $1...$n, and the function's
+name is in $FUNCNAME.
+
+Exit Status:
+Returns success unless NAME is readonly.
+$END
+
+$BUILTIN { ... }
+$DOCNAME grouping_braces
+$SHORT_DOC { COMMANDS ; }
+Group commands as a unit.
+
+Run a set of commands in a group.  This is one way to redirect an
+entire set of commands.
+
+Exit Status:
+Returns the status of the last command executed.
+$END
+
+$BUILTIN %
+$DOCNAME fg_percent
+$SHORT_DOC job_spec [&]
+Resume job in foreground.
+
+Equivalent to the JOB_SPEC argument to the `fg' command.  Resume a
+stopped or background job.  JOB_SPEC can specify either a job name
+or a job number.  Following JOB_SPEC with a `&' places the job in
+the background, as if the job specification had been supplied as an
+argument to `bg'.
+
+Exit Status:
+Returns the status of the resumed job.
+$END
+
+$BUILTIN (( ... ))
+$DOCNAME arith
+$SHORT_DOC (( expression ))
+Evaluate arithmetic expression.
+
+The EXPRESSION is evaluated according to the rules for arithmetic
+evaluation.  Equivalent to `let "EXPRESSION"'.
+
+Exit Status:
+Returns 1 if EXPRESSION evaluates to 0; returns 0 otherwise.
+$END
+
+$BUILTIN [[ ... ]]
+$DOCNAME conditional
+$SHORT_DOC [[ expression ]]
+Execute conditional command.
+
+Returns a status of 0 or 1 depending on the evaluation of the conditional
+expression EXPRESSION.  Expressions are composed of the same primaries used
+by the `test' builtin, and may be combined using the following operators:
+
+  ( EXPRESSION )	Returns the value of EXPRESSION
+  ! EXPRESSION		True if EXPRESSION is false; else false
+  EXPR1 && EXPR2	True if both EXPR1 and EXPR2 are true; else false
+  EXPR1 || EXPR2	True if either EXPR1 or EXPR2 is true; else false
+
+When the `==' and `!=' operators are used, the string to the right of
+the operator is used as a pattern and pattern matching is performed.
+When the `=~' operator is used, the string to the right of the operator
+is matched as a regular expression.
+
+The && and || operators do not evaluate EXPR2 if EXPR1 is sufficient to
+determine the expression's value.
+
+Exit Status:
+0 or 1 depending on value of EXPRESSION.
+$END
+

+		stopped jobs.  If found there, that job is foregrounded.
+		A value of `exact' means that the command word must
+		exactly match a command in the list of stopped jobs.  A
+		value of `substring' means that the command word must
+		match a substring of the job.  Any other value means that
+		the command must be a prefix of a stopped job.
+#if defined (HISTORY)
+#  if defined (BANG_HISTORY)
+histchars	Characters controlling history expansion and quick
+		substitution.  The first character is the history
+		substitution character, usually `!'.  The second is
+		the `quick substitution' character, usually `^'.  The
+		third is the `history comment' character, usually `#'.
+#  endif /* BANG_HISTORY */

+Evaluate conditional expression.
+
+Exits with a status of 0 (true) or 1 (false) depending on
+the evaluation of EXPR.  Expressions may be unary or binary.  Unary
+expressions are often used to examine the status of a file.  There
+are string operators and numeric comparison operators as well.
+
+The behavior of test depends on the number of arguments.  Read the
+bash manual page for the complete specification.
+
+File operators:
+
+  -a FILE        True if file exists.
+  -b FILE        True if file is block special.
+  -c FILE        True if file is character special.
+  -d FILE        True if file is a directory.
+  -e FILE        True if file exists.
+  -f FILE        True if file exists and is a regular file.
+  -g FILE        True if file is set-group-id.
+  -h FILE        True if file is a symbolic link.
+  -L FILE        True if file is a symbolic link.
+  -k FILE        True if file has its `sticky' bit set.
+  -p FILE        True if file is a named pipe.
+  -r FILE        True if file is readable by you.
+  -s FILE        True if file exists and is not empty.
+  -S FILE        True if file is a socket.
+  -t FD          True if FD is opened on a terminal.
+  -u FILE        True if the file is set-user-id.
+  -w FILE        True if the file is writable by you.
+  -x FILE        True if the file is executable by you.
+  -O FILE        True if the file is effectively owned by you.
+  -G FILE        True if the file is effectively owned by your group.
+  -N FILE        True if the file has been modified since it was last read.
+
+  FILE1 -nt FILE2  True if file1 is newer than file2 (according to
+                   modification date).
+
+  FILE1 -ot FILE2  True if file1 is older than file2.
+
+  FILE1 -ef FILE2  True if file1 is a hard link to file2.
+
+String operators:
+
+  -z STRING      True if string is empty.
+
+  -n STRING
+     STRING      True if string is not empty.
+
+  STRING1 = STRING2
+                 True if the strings are equal.
+  STRING1 != STRING2
+                 True if the strings are not equal.
+  STRING1 < STRING2
+                 True if STRING1 sorts before STRING2 lexicographically.
+  STRING1 > STRING2
+                 True if STRING1 sorts after STRING2 lexicographically.
+
+Other operators:
+
+  -o OPTION      True if the shell option OPTION is enabled.
+  -v VAR         True if the shell variable VAR is set.
+  -R VAR         True if the shell variable VAR is set and is a name
+                 reference.
+  ! EXPR         True if expr is false.
+  EXPR1 -a EXPR2 True if both expr1 AND expr2 are true.
+  EXPR1 -o EXPR2 True if either expr1 OR expr2 is true.
+
+  arg1 OP arg2   Arithmetic tests.  OP is one of -eq, -ne,
+                 -lt, -le, -gt, or -ge.
+
+Arithmetic binary operators return true if ARG1 is equal, not-equal,
+less-than, less-than-or-equal, greater-than, or greater-than-or-equal
+than ARG2.

+$FUNCTION trap_builtin
+$SHORT_DOC trap [-lp] [[arg] signal_spec ...]
+Trap signals and other events.
+
+Defines and activates handlers to be run when the shell receives signals
+or other conditions.
+
+ARG is a command to be read and executed when the shell receives the
+signal(s) SIGNAL_SPEC.  If ARG is absent (and a single SIGNAL_SPEC
+is supplied) or `-', each specified signal is reset to its original
+value.  If ARG is the null string each SIGNAL_SPEC is ignored by the
+shell and by the commands it invokes.
+
+If a SIGNAL_SPEC is EXIT (0) ARG is executed on exit from the shell.  If
+a SIGNAL_SPEC is DEBUG, ARG is executed before every simple command.  If
+a SIGNAL_SPEC is RETURN, ARG is executed each time a shell function or a
+script run by the . or source builtins finishes executing.  A SIGNAL_SPEC
+of ERR means to execute ARG each time a command's failure would cause the
+shell to exit when the -e option is enabled.
+
+If no arguments are supplied, trap prints the list of commands associated
+with each signal.
+
+Options:
+  -l	print a list of signal names and their corresponding numbers
+  -p	display the trap commands associated with each SIGNAL_SPEC
+
+Each SIGNAL_SPEC is either a signal name in <signal.h> or a signal number.
+Signal names are case insensitive and the SIG prefix is optional.  A
+signal may be sent to the shell with "kill -signal $$".
+
+Exit Status:
+Returns success unless a SIGSPEC is invalid or an invalid option is given.

+$SHORT_DOC type [-afptP] name [name ...]
+Display information about command type.
+
+For each NAME, indicate how it would be interpreted if used as a
+command name.
+
+Options:
+  -a	display all locations containing an executable named NAME;
+		includes aliases, builtins, and functions, if and only if
+		the `-p' option is not also used
+  -f	suppress shell function lookup
+  -P	force a PATH search for each NAME, even if it is an alias,
+		builtin, or function, and returns the name of the disk file
+		that would be executed
+  -p	returns either the name of the disk file that would be executed,
+		or nothing if `type -t NAME' would not return `file'
+  -t	output a single word which is one of `alias', `keyword',
+		`function', `builtin', `file' or `', if NAME is an alias,
+		shell reserved word, shell function, shell builtin, disk file,
+		or not found, respectively
+
+Arguments:
+  NAME	Command name to be interpreted.
+
+Exit Status:
+Returns success if all of the NAMEs are found; fails if any are not found.

+Modify shell resource limits.
+
+Provides control over the resources available to the shell and processes
+it creates, on systems that allow such control.
+
+Options:
+  -S	use the `soft' resource limit
+  -H	use the `hard' resource limit
+  -a	all current limits are reported
+  -b	the socket buffer size
+  -c	the maximum size of core files created
+  -d	the maximum size of a process's data segment
+  -e	the maximum scheduling priority (`nice')
+  -f	the maximum size of files written by the shell and its children
+  -i	the maximum number of pending signals
+  -k	the maximum number of kqueues allocated for this process
+  -l	the maximum size a process may lock into memory
+  -m	the maximum resident set size
+  -n	the maximum number of open file descriptors
+  -p	the pipe buffer size
+  -q	the maximum number of bytes in POSIX message queues
+  -r	the maximum real-time scheduling priority
+  -s	the maximum stack size
+  -t	the maximum amount of cpu time in seconds
+  -u	the maximum number of user processes
+  -v	the size of virtual memory
+  -x	the maximum number of file locks
+  -P	the maximum number of pseudoterminals
+  -R	the maximum time a real-time process can run before blocking
+  -T	the maximum number of threads
+
+Not all options are available on all platforms.
+
+If LIMIT is given, it is the new value of the specified resource; the
+special LIMIT values `soft', `hard', and `unlimited' stand for the
+current soft limit, the current hard limit, and no limit, respectively.
+Otherwise, the current value of the specified resource is printed.  If
+no option is given, then -f is assumed.
+
+Values are in 1024-byte increments, except for -t, which is in seconds,
+-p, which is in increments of 512 bytes, and -u, which is an unscaled
+number of processes.
+
+Exit Status:
+Returns success unless an invalid option is supplied or an error occurs.

+$FUNCTION umask_builtin
+$SHORT_DOC umask [-p] [-S] [mode]
+Display or set file mode mask.
+
+Sets the user file-creation mask to MODE.  If MODE is omitted, prints
+the current value of the mask.
+
+If MODE begins with a digit, it is interpreted as an octal number;
+otherwise it is a symbolic mode string like that accepted by chmod(1).
+
+Options:
+  -p	if MODE is omitted, output in a form that may be reused as input
+  -S	makes the output symbolic; otherwise an octal number is output
+
+Exit Status:
+Returns success unless MODE is invalid or an invalid option is given.

+$BUILTIN wait
+$FUNCTION wait_builtin
+$DEPENDS_ON JOB_CONTROL
+$PRODUCES wait.c
+$SHORT_DOC wait [-fn] [-p var] [id ...]
+Wait for job completion and return exit status.
+
+Waits for each process identified by an ID, which may be a process ID or a
+job specification, and reports its termination status.  If ID is not
+given, waits for all currently active child processes, and the return
+status is zero.  If ID is a job specification, waits for all processes
+in that job's pipeline.
+
+If the -n option is supplied, waits for a single job from the list of IDs,
+or, if no IDs are supplied, for the next job to complete and returns its
+exit status.
+
+If the -p option is supplied, the process or job identifier of the job
+for which the exit status is returned is assigned to the variable VAR
+named by the option argument. The variable will be unset initially, before
+any assignment. This is useful only when the -n option is supplied.
+
+If the -f option is supplied, and job control is enabled, waits for the
+specified ID to terminate, instead of waiting for it to change status.
+
+Exit Status:
+Returns the status of the last ID; fails if ID is invalid or an invalid
+option is given, or if -n is supplied and the shell has no unwaited-for
+children.
+$END

+Wait for process completion and return exit status.

+Waits for each process specified by a PID and reports its termination status.
+If PID is not given, waits for all currently active child processes,
+and the return status is zero.  PID must be a process ID.
+
+Exit Status:
+Returns the status of the last PID; fails if PID is invalid or an invalid
+option is given.

+\`configure' configures bash 5.2-release to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+   Here is a matrix of mmap possibilities:
+	mmap private not fixed
+	mmap private fixed at somewhere currently unmapped
+	mmap private fixed at somewhere already mapped
+	mmap shared not fixed
+	mmap shared fixed at somewhere currently unmapped
+	mmap shared fixed at somewhere already mapped
+   For private mappings, we should verify that changes cannot be read()
+   back from the file, nor mmap's back from the file at a different
+   address.  (There have been systems where private was not correctly
+   implemented like the infamous i386 svr4.0, and systems where the
+   VM page cache was not coherent with the file system buffer cache
+   like early versions of FreeBSD and possibly contemporary NetBSD.)
+   For shared mappings, we should conversely verify that changes get
+   propagated back to all the places they're supposed to be.
+
+   Grep wants private fixed already mapped.
+   The main things grep needs to know about mmap are:
+   * does it exist and is it safe to write into the mmap'd area
+   * how to use it (BSD variants)  */

+	mmap private fixed at somewhere currently unmapped
+	mmap private fixed at somewhere already mapped
+	mmap shared not fixed
+	mmap shared fixed at somewhere currently unmapped
+	mmap shared fixed at somewhere already mapped
+   For private mappings, we should verify that changes cannot be read()
+   back from the file, nor mmap's back from the file at a different
+   address.  (There have been systems where private was not correctly
+   implemented like the infamous i386 svr4.0, and systems where the
+   VM page cache was not coherent with the file system buffer cache
+   like early versions of FreeBSD and possibly contemporary NetBSD.)
+   For shared mappings, we should conversely verify that changes get
+   propagated back to all the places they're supposed to be.
+
+   Grep wants private fixed already mapped.
+   The main things grep needs to know about mmap are:
+   * does it exist and is it safe to write into the mmap'd area
+   * how to use it (BSD variants)  */

+		       BASH - The Bourne-Again Shell
+
+Bash is the shell, or command language interpreter, that will appear
+in the GNU operating system.  Bash is an sh-compatible shell that
+incorporates useful features from the Korn shell (ksh) and C shell
+(csh).  It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2
+Shell and Tools standard.  It offers functional improvements over sh
+for both programming and interactive use.  In addition, most sh scripts
+can be run by Bash without modification. 
+
+Bash is quite portable.  It uses a configuration system that discovers
+characteristics of the compilation platform at build time, and may
+therefore be built on nearly every version of UNIX.  Ports to
+UNIX-like systems such as QNX and Minix and to non-UNIX systems such
+as OS/2, Windows 95, and Windows NT are available. 
+
+Bash includes the following features:
+
+Editing and Completion
+
+Bash offers a command-line editing facility which permits users to
+edit command lines using familiar emacs or vi-style editing commands.
+Editing allows corrections to be made without having to erase back
+to the point of error or start the command line anew.  The editing
+facilities include a feature that allows users to complete command and
+file names.
+
+The Bash line editing library is fully customizable.  Users may define
+their own key bindings -- the action taken when a key is pressed.  A
+number of variables to fine-tune editing behavior are also available.
+
+History and Command Re-entry
+
+The Bash history feature remembers commands entered to the shell and
+allows them to be recalled and re-executed.  The history list may be
+of unlimited size.  Bash allows users to search for previous commands
+and reuse portions of those commands when composing new ones.  The
+history list may be saved across shell sessions. 
+
+Bash allows users to control which commands are saved on the history
+list.
+
+Job Control
+
+On systems that support it, Bash provides an interface to the
+operating system's job control facilities, which allow processes
+to be suspended and restarted, and moved between the foreground
+and background.  Bash allows users to selectively `forget' about
+background jobs. 
+
+Shell Functions and Aliases
+
+These mechanisms are available to bind a user-selected identifier to a
+list of commands that will be executed when the identifier is used as
+a command name.  Functions allow local variables and recursion, and
+have access to the environment of the calling shell.  Aliases may be
+used to create a mnemonic for a command name, expand a single word to
+a complex command, or ensure that a command is called with a basic set
+of options. 
+
+Arrays
+
+Bash-2.0 supports indexed arrays of unlimited size.  The subscript for
+an array is an arithmetic expression.  Arrays may be assigned to with
+a new compound assignment syntax, and several builtins have options to
+operate on array variables.  Bash includes a number of built-in array
+variables.
+
+Arithmetic
+
+Bash allows users to perform integer arithmetic in any base from two
+to sixty-four.  Nearly all of the C language arithmetic operators are
+available with the same syntax and precedence as in C.  Arithmetic
+expansion allows an arithmetic expression to be evaluated and the
+result substituted into the command line.  Shell variables can be used
+as operands, and the value of an expression may be assigned to a
+variable. 
+
+An arithmetic expression may be used as a command; the exit status of
+the command is the value of the expression.
+
+ANSI-C Quoting
+
+There is a new quoting syntax that allows backslash-escaped characters
+in strings to be expanded according to the ANSI C standard.
+
+Tilde Expansion
+
+Users' home directories may be expanded using this feature.  Words
+beginning with a tilde may also be expanded to the current or previous
+working directory.
+
+Brace Expansion
+
+Brace expansion is a convenient way to generate a list of strings that
+share a common prefix or suffix.
+
+Substring Capabilities
+
+Bash allows new strings to be created by removing leading or trailing
+substrings from existing variable values, or by specifying a starting
+offset and length.  Portions of variable values may be matched against
+shell patterns and the matching portion removed or a new value
+substituted. 
+
+Indirect Variable Expansion
+
+Bash makes it easy to find the value of a shell variable whose name is
+the value of another variable.
+
+Expanded I/O Capabilities
+
+Bash provides several input and output features not available in sh,
+including the ability to:
+
+	o specify a file or file descriptor for both input and output
+	o read from or write to asynchronous processes using named pipes
+	o read lines ending in backslash
+	o display a prompt on the terminal before a read
+	o format menus and interpret responses to them
+	o echo lines exactly as input without escape processing
+
+Control of Builtin Commands
+
+Bash implements several builtin commands to give users more control
+over which commands are executed.  The enable builtin allows other
+builtin commands to be selectively enabled or disabled.  The command
+and builtin builtins change the order in which the shell searches for
+commands. 
+
+On systems that provide dynamic loading, new builtins may be loaded
+into a running shell from a shared object file.  These new builtins
+have access to all of the shell facilities.
+
+Help
+
+Bash includes a built-in help facility.
+
+Shell Optional Behavior
+
+There is a great deal of customizable shell behavior.  The shopt
+builtin command provides a unified interface that allows users to
+alter shell defaults. 
+
+Prompt Customization
+
+Bash allows the primary and secondary prompts to be customized by
+interpreting a number of backslash-escaped special characters. 
+Parameter and variable expansion is also performed on the values of
+the primary and secondary prompt strings before they are displayed. 
+
+Security
+
+Bash provides a restricted shell environment.  It is also possible to
+control the execution of setuid/setgid scripts. 
+
+Directory Stack
+
+Bash provides a `directory stack', to which directories may be added
+and removed.  The current directory may be changed to any directory in
+the stack.  It is easy to toggle between two directories in the stack. 
+The directory stack may be saved and restored across different shell
+invocations. 
+
+POSIX Mode
+
+Bash is nearly completely conformant to POSIX.2.  POSIX mode changes
+those few areas where the Bash default behavior differs from the
+standard to match the standard.  In POSIX mode, Bash is POSIX.2
+compliant. 
+
+Internationalization
+
+Bash provides a new quoting syntax that allows strings to be
+translated according to the current locale.  The locale in which the
+shell itself runs may also be changed, so that the shell messages
+themselves may be language-specific. 
+
+The command-line editing facilities allow the input of eight-bit
+characters, so most of the ISO-8859 family of character sets are
+supported. 
+
+Command Timing
+
+Bash allows external commands, shell builtin commands and shell functions
+to be timed.  The format used to display the timing information may be
+changed by the user.

+
+DDEESSCCRRIIPPTTIIOONN
+       BBaasshh  is  an  sshh-compatible  command language interpreter that executes
+       commands read from the standard input or from a file.  BBaasshh also incor-
+       porates useful features from the _K_o_r_n and _C shells (kksshh and ccsshh).
+
+       BBaasshh  is  intended  to  be a conformant implementation of the Shell and
+       Utilities portion  of  the  IEEE  POSIX  specification  (IEEE  Standard
+       1003.1).  BBaasshh can be configured to be POSIX-conformant by default.
+
+OOPPTTIIOONNSS
+       All of the single-character shell options documented in the description
+       of the sseett builtin command, including --oo, can be used as  options  when
+       the  shell  is invoked.  In addition, bbaasshh interprets the following op-
+       tions when it is invoked:
+
+       --cc        If the --cc option is present, then commands are read from  the
+                 first non-option argument _c_o_m_m_a_n_d___s_t_r_i_n_g.  If there are argu-
+                 ments after the _c_o_m_m_a_n_d___s_t_r_i_n_g, the  first  argument  is  as-
+                 signed  to $$00 and any remaining arguments are assigned to the
+                 positional parameters.  The assignment to $$00 sets the name of
+                 the shell, which is used in warning and error messages.
+       --ii        If the --ii option is present, the shell is _i_n_t_e_r_a_c_t_i_v_e.
+       --ll        Make bbaasshh act as if it had been invoked as a login shell (see
+                 IINNVVOOCCAATTIIOONN below).
+       --rr        If the --rr option is present,  the  shell  becomes  _r_e_s_t_r_i_c_t_e_d
+                 (see RREESSTTRRIICCTTEEDD SSHHEELLLL below).
+       --ss        If  the --ss option is present, or if no arguments remain after
+                 option processing, then commands are read from  the  standard
+                 input.   This  option  allows the positional parameters to be
+                 set when invoking an interactive shell or when reading  input
+                 through a pipe.
+       --DD        A  list of all double-quoted strings preceded by $$ is printed
+                 on the standard output.  These are the strings that are  sub-
+                 ject to language translation when the current locale is not CC
+                 or PPOOSSIIXX.  This implies the --nn option; no  commands  will  be
+                 executed.
+       [[--++]]OO [[_s_h_o_p_t___o_p_t_i_o_n]]
+                 _s_h_o_p_t___o_p_t_i_o_n  is  one  of  the  shell options accepted by the
+                 sshhoopptt  builtin  (see  SSHHEELLLL  BBUUIILLTTIINN  CCOOMMMMAANNDDSS  below).    If
+                 _s_h_o_p_t___o_p_t_i_o_n is present, --OO sets the value of that option; ++OO
+                 unsets it.  If _s_h_o_p_t___o_p_t_i_o_n is not supplied,  the  names  and
+                 values  of the shell options accepted by sshhoopptt are printed on
+                 the standard output.  If the invocation  option  is  ++OO,  the
+                 output is displayed in a format that may be reused as input.
+       ----        A  ----  signals the end of options and disables further option
+                 processing.  Any arguments after the ---- are treated as  file-
+                 names and arguments.  An argument of -- is equivalent to ----.
+
+       BBaasshh  also  interprets  a number of multi-character options.  These op-
+       tions must appear on the command line before the  single-character  op-
+       tions to be recognized.
+
+       ----ddeebbuuggggeerr
+              Arrange for the debugger profile to be executed before the shell
+              starts.  Turns on extended debugging mode (see  the  description
+              of the eexxttddeebbuugg option to the sshhoopptt builtin below).
+       ----dduummpp--ppoo--ssttrriinnggss
+              Equivalent  to --DD, but the output is in the GNU _g_e_t_t_e_x_t ppoo (por-
+              table object) file format.
+       ----dduummpp--ssttrriinnggss

+       ----rrccffiillee _f_i_l_e
+              Execute commands from _f_i_l_e instead of the standard personal ini-

+              VVOOCCAATTIIOONN below).
+
+       ----llooggiinn
+              Equivalent to --ll.
+
+       ----nnooeeddiittiinngg
+              Do  not  use the GNU rreeaaddlliinnee library to read command lines when
+              the shell is interactive.
+
+       ----nnoopprrooffiillee
+              Do not read either the system-wide startup file _/_e_t_c_/_p_r_o_f_i_l_e  or
+              any   of  the  personal  initialization  files  _~_/_._b_a_s_h___p_r_o_f_i_l_e,
+              _~_/_._b_a_s_h___l_o_g_i_n, or _~_/_._p_r_o_f_i_l_e.   By  default,  bbaasshh  reads  these
+              files  when  it  is invoked as a login shell (see IINNVVOOCCAATTIIOONN be-
+              low).
+
+       ----nnoorrcc Do  not  read  and  execute  the  personal  initialization  file
+              _~_/_._b_a_s_h_r_c if the shell is interactive.  This option is on by de-
+              fault if the shell is invoked as sshh.
+
+       ----ppoossiixx
+              Change the behavior of bbaasshh where the default operation  differs
+              from the POSIX standard to match the standard (_p_o_s_i_x _m_o_d_e).  See
+              SSEEEE AALLSSOO below for a reference to a document  that  details  how
+              posix mode affects bash's behavior.
+
+       ----rreessttrriicctteedd
+              The shell becomes restricted (see RREESSTTRRIICCTTEEDD SSHHEELLLL below).
+
+       ----vveerrbboossee
+              Equivalent to --vv.
+
+       ----vveerrssiioonn
+              Show  version information for this instance of bbaasshh on the stan-
+              dard output and exit successfully.
+
+AARRGGUUMMEENNTTSS
+       If arguments remain after option processing, and neither the --cc nor the
+       --ss  option  has  been supplied, the first argument is assumed to be the
+       name of a file containing shell commands.  If bbaasshh is invoked  in  this
+       fashion,  $$00 is set to the name of the file, and the positional parame-
+       ters are set to the remaining arguments.  BBaasshh reads and executes  com-
+       mands  from this file, then exits.  BBaasshh's exit status is the exit sta-
+       tus of the last command executed in the script.  If no commands are ex-
+       ecuted,  the  exit  status  is 0.  An attempt is first made to open the
+       file in the current directory, and, if no file is found, then the shell
+       searches the directories in PPAATTHH for the script.
+
+IINNVVOOCCAATTIIOONN
+       A  _l_o_g_i_n _s_h_e_l_l is one whose first character of argument zero is a --, or
+       one started with the ----llooggiinn option.
+
+       An _i_n_t_e_r_a_c_t_i_v_e shell is one started without non-option  arguments  (un-
+       less  --ss  is specified) and without the --cc option, whose standard input
+       and error are both connected to terminals (as determined by _i_s_a_t_t_y(3)),
+       or  one  started  with  the --ii option.  PPSS11 is set and $$-- includes ii if
+       bbaasshh is interactive, allowing a shell script or a startup file to  test
+       this state.
+
+       The  following paragraphs describe how bbaasshh executes its startup files.
+       If any of the files exist but cannot be read, bbaasshh  reports  an  error.
+       Tildes  are expanded in filenames as described below under TTiillddee EExxppaann--
+       ssiioonn in the EEXXPPAANNSSIIOONN section.
+
+       When bbaasshh is invoked as an interactive login shell, or as a  non-inter-
+       active  shell with the ----llooggiinn option, it first reads and executes com-
+       mands from the file _/_e_t_c_/_p_r_o_f_i_l_e, if that file exists.   After  reading
+       that file, it looks for _~_/_._b_a_s_h___p_r_o_f_i_l_e, _~_/_._b_a_s_h___l_o_g_i_n, and _~_/_._p_r_o_f_i_l_e,
+       in that order, and reads and executes commands from the first one  that
+       exists  and  is  readable.  The ----nnoopprrooffiillee option may be used when the
+       shell is started to inhibit this behavior.
+
+       When an interactive login shell exits, or a non-interactive login shell
+       executes  the  eexxiitt  builtin  command, bbaasshh reads and executes commands
+       from the file _~_/_._b_a_s_h___l_o_g_o_u_t, if it exists.
+
+       When an interactive shell that is not a login shell  is  started,  bbaasshh
+       reads  and executes commands from _~_/_._b_a_s_h_r_c, if that file exists.  This
+       may be inhibited by using the ----nnoorrcc option.  The ----rrccffiillee _f_i_l_e  option
+       will  force  bbaasshh  to  read  and  execute commands from _f_i_l_e instead of
+       _~_/_._b_a_s_h_r_c.
+
+       When bbaasshh is started non-interactively, to run a shell script, for  ex-
+       ample,  it  looks for the variable BBAASSHH__EENNVV in the environment, expands
+       its value if it appears there, and uses the expanded value as the  name
+       of  a  file to read and execute.  BBaasshh behaves as if the following com-
+       mand were executed:
+              if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi
+       but the value of the PPAATTHH variable is not used to search for the  file-
+       name.
+
+       If  bbaasshh is invoked with the name sshh, it tries to mimic the startup be-
+       havior of historical versions of sshh as closely as possible, while  con-
+       forming  to the POSIX standard as well.  When invoked as an interactive
+       login shell, or a non-interactive shell with  the  ----llooggiinn  option,  it
+       first  attempts  to  read  and  execute  commands from _/_e_t_c_/_p_r_o_f_i_l_e and
+       _~_/_._p_r_o_f_i_l_e, in that order.  The ----nnoopprrooffiillee option may be used  to  in-
+       hibit  this  behavior.   When  invoked as an interactive shell with the
+       name sshh, bbaasshh looks for the variable EENNVV, expands its value  if  it  is
+       defined,  and uses the expanded value as the name of a file to read and
+       execute.  Since a shell invoked as sshh does not attempt to read and exe-
+       cute  commands from any other startup files, the ----rrccffiillee option has no
+       effect.  A non-interactive shell invoked with the name sshh does not  at-
+       tempt to read any other startup files.  When invoked as sshh, bbaasshh enters
+       _p_o_s_i_x mode after the startup files are read.
+
+       When bbaasshh is started in _p_o_s_i_x mode, as with the  ----ppoossiixx  command  line
+       option, it follows the POSIX standard for startup files.  In this mode,
+       interactive shells expand the EENNVV variable and commands  are  read  and
+       executed  from  the  file  whose  name is the expanded value.  No other
+       startup files are read.
+
+       BBaasshh attempts to determine when it is being run with its standard input
+       connected  to  a network connection, as when executed by the historical
+       remote shell daemon, usually _r_s_h_d, or the secure shell daemon _s_s_h_d.  If
+       bbaasshh  determines  it is being run non-interactively in this fashion, it
+       reads and executes commands from _~_/_._b_a_s_h_r_c, if that file exists and  is
+       readable.  It will not do this if invoked as sshh.  The ----nnoorrcc option may
+       be used to inhibit this behavior, and the ----rrccffiillee option may  be  used
+       to  force  another file to be read, but neither _r_s_h_d nor _s_s_h_d generally
+       invoke the shell with those options or allow them to be specified.
+
+       If the shell is started with the effective user (group) id not equal to
+       the real user (group) id, and the --pp option is not supplied, no startup
+       files are read, shell functions are not inherited from the environment,
+       the  SSHHEELLLLOOPPTTSS, BBAASSHHOOPPTTSS, CCDDPPAATTHH, and GGLLOOBBIIGGNNOORREE variables, if they ap-
+       pear in the environment, are ignored, and the effective user id is  set
+       to  the  real user id.  If the --pp option is supplied at invocation, the
+       startup behavior is the same, but the effective user id is not reset.

+
+   SSiimmppllee CCoommmmaannddss
+       A _s_i_m_p_l_e _c_o_m_m_a_n_d is a sequence of optional  variable  assignments  fol-
+       lowed  by  bbllaannkk-separated  words and redirections, and terminated by a
+       _c_o_n_t_r_o_l _o_p_e_r_a_t_o_r.  The first word specifies the command to be executed,
+       and  is passed as argument zero.  The remaining words are passed as ar-
+       guments to the invoked command.
+
+       The return value of a _s_i_m_p_l_e _c_o_m_m_a_n_d is its exit status,  or  128+_n  if
+       the command is terminated by signal _n.
+
+   PPiippeelliinneess
+       A  _p_i_p_e_l_i_n_e  is  a sequence of one or more commands separated by one of

+
+              [ttiimmee [--pp]] [ ! ] _c_o_m_m_a_n_d_1 [ [|||||&&] _c_o_m_m_a_n_d_2 ... ]
+
+       The standard output of _c_o_m_m_a_n_d_1 is connected via a pipe to the standard
+       input  of  _c_o_m_m_a_n_d_2.   This connection is performed before any redirec-
+       tions specified by the _c_o_m_m_a_n_d_1(see RREEDDIIRREECCTTIIOONN below).  If ||&& is used,
+       _c_o_m_m_a_n_d_1's  standard error, in addition to its standard output, is con-
+       nected to _c_o_m_m_a_n_d_2's standard input through the pipe; it  is  shorthand
+       for  22>>&&11  ||.   This  implicit redirection of the standard error to the
+       standard output is performed after any redirections specified  by  _c_o_m_-
+       _m_a_n_d_1.
+
+       The return status of a pipeline is the exit status of the last command,
+       unless the ppiippeeffaaiill option is enabled.  If  ppiippeeffaaiill  is  enabled,  the
+       pipeline's  return  status is the value of the last (rightmost) command
+       to exit with a non-zero status, or zero if all commands  exit  success-
+       fully.  If the reserved word !!  precedes a pipeline, the exit status of
+       that pipeline is the logical negation of the exit status  as  described
+       above.   The  shell waits for all commands in the pipeline to terminate
+       before returning a value.
+
+       If the ttiimmee reserved word precedes a pipeline, the elapsed as  well  as
+       user  and  system  time consumed by its execution are reported when the
+       pipeline terminates.  The --pp option changes the output format  to  that
+       specified  by POSIX.  When the shell is in _p_o_s_i_x _m_o_d_e, it does not rec-
+       ognize ttiimmee as a reserved word if the next token  begins  with  a  `-'.
+       The  TTIIMMEEFFOORRMMAATT  variable  may be set to a format string that specifies
+       how the timing information should be displayed; see the description  of
+       TTIIMMEEFFOORRMMAATT under SShheellll VVaarriiaabblleess below.
+
+       When the shell is in _p_o_s_i_x _m_o_d_e, ttiimmee may be followed by a newline.  In
+       this case, the shell displays the total user and system  time  consumed
+       by  the shell and its children.  The TTIIMMEEFFOORRMMAATT variable may be used to
+       specify the format of the time information.
+
+       Each command in a multi-command pipeline, where pipes are  created,  is
+       executed  in a _s_u_b_s_h_e_l_l, which is a separate process.  See CCOOMMMMAANNDD EEXXEE--
+       CCUUTTIIOONN EENNVVIIRROONNMMEENNTT for a description of subshells and a subshell  envi-
+       ronment.   If  the  llaassttppiippee  option is enabled using the sshhoopptt builtin
+       (see the description of sshhoopptt below), the last element  of  a  pipeline
+       may be run by the shell process when job control is not active.
+
+   LLiissttss
+       A  _l_i_s_t  is a sequence of one or more pipelines separated by one of the
+       operators ;;, &&, &&&&, or ||||, and optionally terminated by one of ;;, &&, or
+       <<nneewwlliinnee>>.
+
+       Of these list operators, &&&& and |||| have equal precedence, followed by ;;
+       and &&, which have equal precedence.
+
+       A sequence of one or more newlines may appear in a _l_i_s_t  instead  of  a
+       semicolon to delimit commands.
+
+       If  a  command  is terminated by the control operator &&, the shell exe-
+       cutes the command in the _b_a_c_k_g_r_o_u_n_d in a subshell.  The shell does  not
+       wait  for the command to finish, and the return status is 0.  These are
+       referred to as _a_s_y_n_c_h_r_o_n_o_u_s commands.  Commands separated by  a  ;;  are
+       executed sequentially; the shell waits for each command to terminate in
+       turn.  The return status is the exit status of the  last  command  exe-
+       cuted.
+
+       AND  and  OR  lists are sequences of one or more pipelines separated by
+       the &&&& and |||| control operators, respectively.  AND and  OR  lists  are
+       executed with left associativity.  An AND list has the form
+
+              _c_o_m_m_a_n_d_1 &&&& _c_o_m_m_a_n_d_2
+
+       _c_o_m_m_a_n_d_2  is  executed if, and only if, _c_o_m_m_a_n_d_1 returns an exit status
+       of zero (success).
+
+       An OR list has the form
+
+              _c_o_m_m_a_n_d_1 |||| _c_o_m_m_a_n_d_2
+
+       _c_o_m_m_a_n_d_2 is executed if, and only if, _c_o_m_m_a_n_d_1 returns a non-zero  exit
+       status.   The  return  status of AND and OR lists is the exit status of
+       the last command executed in the list.
+
+   CCoommppoouunndd CCoommmmaannddss
+       A _c_o_m_p_o_u_n_d _c_o_m_m_a_n_d is one of the following.  In most cases a _l_i_s_t in  a
+       command's  description may be separated from the rest of the command by
+       one or more newlines, and may be followed by a newline in  place  of  a
+       semicolon.
+
+       (_l_i_s_t) _l_i_s_t  is  executed in a subshell (see CCOOMMMMAANNDD EEXXEECCUUTTIIOONN EENNVVIIRROONN--
+              MMEENNTT below for a description of a subshell environment).   Vari-
+              able  assignments  and  builtin commands that affect the shell's
+              environment do not remain in effect after the command completes.
+              The return status is the exit status of _l_i_s_t.
+
+       { _l_i_s_t; }
+              _l_i_s_t  is simply executed in the current shell environment.  _l_i_s_t
+              must be terminated with a newline or semicolon.  This  is  known
+              as  a  _g_r_o_u_p  _c_o_m_m_a_n_d.   The return status is the exit status of
+              _l_i_s_t.  Note that unlike the metacharacters (( and )), {{ and }}  are
+              _r_e_s_e_r_v_e_d _w_o_r_d_s and must occur where a reserved word is permitted
+              to be recognized.  Since they do not cause a  word  break,  they
+              must  be  separated  from  _l_i_s_t  by  whitespace or another shell
+              metacharacter.
+
+       ((_e_x_p_r_e_s_s_i_o_n))
+              The _e_x_p_r_e_s_s_i_o_n is evaluated according to the rules described be-
+              low under AARRIITTHHMMEETTIICC EEVVAALLUUAATTIIOONN.  If the value of the expression
+              is non-zero, the return status is 0; otherwise the return status
+              is  1.   The  _e_x_p_r_e_s_s_i_o_n  undergoes the same expansions as if it
+              were within double quotes, but double quote  characters  in  _e_x_-
+              _p_r_e_s_s_i_o_n are not treated specially and are removed.
+
+       [[[[ _e_x_p_r_e_s_s_i_o_n ]]]]
+              Return  a  status  of  0 or 1 depending on the evaluation of the
+              conditional expression _e_x_p_r_e_s_s_i_o_n.  Expressions are composed  of
+              the  primaries  described  below  under CCOONNDDIITTIIOONNAALL EEXXPPRREESSSSIIOONNSS.
+              The words between the [[[[ and ]]]] do not  undergo  word  splitting
+              and pathname expansion.  The shell performs tilde expansion, pa-
+              rameter and variable expansion,  arithmetic  expansion,  command
+              substitution,  process  substitution, and quote removal on those
+              words (the expansions that would occur if  the  words  were  en-
+              closed in double quotes).  Conditional operators such as --ff must
+              be unquoted to be recognized as primaries.
+
+              When used with [[[[, the << and >> operators sort  lexicographically
+              using the current locale.
+
+              When  the  ==== and !!== operators are used, the string to the right
+              of the operator is considered a pattern and matched according to
+              the rules described below under PPaatttteerrnn MMaattcchhiinngg, as if the eexxtt--
+              gglloobb shell option were enabled.  The == operator is equivalent to
+              ====.   If  the  nnooccaasseemmaattcchh shell option is enabled, the match is
+              performed without regard to the case of  alphabetic  characters.
+              The  return  value  is  0 if the string matches (====) or does not
+              match (!!==) the pattern, and 1 otherwise.  Any part of  the  pat-
+              tern  may be quoted to force the quoted portion to be matched as
+              a string.
+
+              An additional binary operator, ==~~, is available, with  the  same
+              precedence  as  ====  and  !!==.  When it is used, the string to the
+              right of the operator is considered a POSIX extended regular ex-
+              pression  and  matched  accordingly (using the POSIX _r_e_g_c_o_m_p and
+              _r_e_g_e_x_e_c interfaces usually described in _r_e_g_e_x(3)).   The  return
+              value  is  0 if the string matches the pattern, and 1 otherwise.
+              If the regular expression is syntactically incorrect, the condi-
+              tional expression's return value is 2.  If the nnooccaasseemmaattcchh shell
+              option is enabled, the match is performed without regard to  the
+              case  of  alphabetic  characters.  If any part of the pattern is
+              quoted, the quoted portion is matched literally.  This means ev-
+              ery  character  in the quoted portion matches itself, instead of
+              having any special pattern matching meaning.  If the pattern  is
+              stored  in  a  shell  variable,  quoting  the variable expansion
+              forces the  entire  pattern  to  be  matched  literally.   Treat
+              bracket expressions in regular expressions carefully, since nor-
+              mal quoting and pattern characters lose their  meanings  between
+              brackets.
+
+              The  pattern  will  match  if it matches any part of the string.
+              Anchor the pattern using the ^^ and $$ regular  expression  opera-
+              tors to force it to match the entire string.  The array variable
+              BBAASSHH__RREEMMAATTCCHH records which parts of the string matched the  pat-
+              tern.   The  element  of  BBAASSHH__RREEMMAATTCCHH with index 0 contains the
+              portion of the string matching the  entire  regular  expression.
+              Substrings  matched  by  parenthesized subexpressions within the
+              regular expression are saved in the remaining  BBAASSHH__RREEMMAATTCCHH  in-
+              dices.  The  element of BBAASSHH__RREEMMAATTCCHH with index _n is the portion
+              of the string  matching  the  _nth  parenthesized  subexpression.
+              Bash  sets  BBAASSHH__RREEMMAATTCCHH  in the global scope; declaring it as a
+              local variable will lead to unexpected results.
+
+              Expressions may  be  combined  using  the  following  operators,
+              listed in decreasing order of precedence:
+
+              (( _e_x_p_r_e_s_s_i_o_n ))
+                     Returns  the  value  of  _e_x_p_r_e_s_s_i_o_n.  This may be used to
+                     override the normal precedence of operators.
+              !! _e_x_p_r_e_s_s_i_o_n
+                     True if _e_x_p_r_e_s_s_i_o_n is false.
+              _e_x_p_r_e_s_s_i_o_n_1 &&&& _e_x_p_r_e_s_s_i_o_n_2
+                     True if both _e_x_p_r_e_s_s_i_o_n_1 and _e_x_p_r_e_s_s_i_o_n_2 are true.
+              _e_x_p_r_e_s_s_i_o_n_1 |||| _e_x_p_r_e_s_s_i_o_n_2
+                     True if either _e_x_p_r_e_s_s_i_o_n_1 or _e_x_p_r_e_s_s_i_o_n_2 is true.
+
+              The &&&& and |||| operators do not evaluate _e_x_p_r_e_s_s_i_o_n_2 if the value
+              of  _e_x_p_r_e_s_s_i_o_n_1  is  sufficient to determine the return value of
+              the entire conditional expression.
+
+       ffoorr _n_a_m_e [ [ iinn [ _w_o_r_d _._._. ] ] ; ] ddoo _l_i_s_t ; ddoonnee
+              The list of words following iinn is expanded, generating a list of
+              items.  The variable _n_a_m_e is set to each element of this list in
+              turn, and _l_i_s_t is executed each time.  If the iinn _w_o_r_d  is  omit-
+              ted,  the ffoorr command executes _l_i_s_t once for each positional pa-
+              rameter that is set (see PPAARRAAMMEETTEERRSS below).  The  return  status
+              is  the  exit  status of the last command that executes.  If the
+              expansion of the items following iinn results in an empty list, no
+              commands are executed, and the return status is 0.
+
+       ffoorr (( _e_x_p_r_1 ; _e_x_p_r_2 ; _e_x_p_r_3 )) ; ddoo _l_i_s_t ; ddoonnee
+              First, the arithmetic expression _e_x_p_r_1 is evaluated according to
+              the rules described  below  under  AARRIITTHHMMEETTIICC  EEVVAALLUUAATTIIOONN.   The
+              arithmetic  expression  _e_x_p_r_2 is then evaluated repeatedly until
+              it evaluates to zero.  Each time _e_x_p_r_2 evaluates to  a  non-zero
+              value,  _l_i_s_t  is executed and the arithmetic expression _e_x_p_r_3 is
+              evaluated.  If any expression is omitted, it behaves  as  if  it
+              evaluates to 1.  The return value is the exit status of the last
+              command in _l_i_s_t that is executed, or false if any of the expres-
+              sions is invalid.
+
+       sseelleecctt _n_a_m_e [ iinn _w_o_r_d ] ; ddoo _l_i_s_t ; ddoonnee
+              The list of words following iinn is expanded, generating a list of
+              items, and the set of expanded words is printed on the  standard
+              error,  each  preceded  by a number.  If the iinn _w_o_r_d is omitted,
+              the positional parameters are printed  (see  PPAARRAAMMEETTEERRSS  below).
+              sseelleecctt  then  displays  the PPSS33 prompt and reads a line from the
+              standard input.  If the line consists of a number  corresponding
+              to  one of the displayed words, then the value of _n_a_m_e is set to
+              that word.  If the line is empty, the words and prompt are  dis-
+              played  again.  If EOF is read, the sseelleecctt command completes and
+              returns 1.  Any other value read causes _n_a_m_e to be set to  null.
+              The  line read is saved in the variable RREEPPLLYY.  The _l_i_s_t is exe-
+              cuted after each selection until a bbrreeaakk  command  is  executed.
+              The exit status of sseelleecctt is the exit status of the last command
+              executed in _l_i_s_t, or zero if no commands were executed.
+
+       ccaassee _w_o_r_d iinn [ [(] _p_a_t_t_e_r_n [ || _p_a_t_t_e_r_n ] ... ) _l_i_s_t ;; ] ... eessaacc
+              A ccaassee command first expands _w_o_r_d, and tries to match it against
+              each  _p_a_t_t_e_r_n  in turn, using the matching rules described under
+              PPaatttteerrnn MMaattcchhiinngg below.  The _w_o_r_d is expanded using tilde expan-
+              sion,  parameter  and  variable expansion, arithmetic expansion,
+              command substitution, process substitution  and  quote  removal.
+              Each _p_a_t_t_e_r_n examined is expanded using tilde expansion, parame-
+              ter and variable expansion, arithmetic expansion,  command  sub-
+              stitution,  process substitution, and quote removal.  If the nnoo--
+              ccaasseemmaattcchh shell option is enabled, the match is performed  with-
+              out  regard  to the case of alphabetic characters.  When a match
+              is found, the corresponding _l_i_s_t is executed.  If the ;;;;  opera-
+              tor is used, no subsequent matches are attempted after the first
+              pattern match.  Using ;;&& in place of ;;;; causes execution to con-
+              tinue  with  the  _l_i_s_t associated with the next set of patterns.
+              Using ;;;;&& in place of ;;;; causes the shell to test the next  pat-
+              tern  list  in the statement, if any, and execute any associated
+              _l_i_s_t on a successful match, continuing the case statement execu-
+              tion as if the pattern list had not matched.  The exit status is
+              zero if no pattern matches.  Otherwise, it is the exit status of
+              the last command executed in _l_i_s_t.

+              The  iiff  _l_i_s_t is executed.  If its exit status is zero, the tthheenn
+              _l_i_s_t is executed.  Otherwise, each  eelliiff  _l_i_s_t  is  executed  in
+              turn,  and  if  its  exit status is zero, the corresponding tthheenn
+              _l_i_s_t is executed and the command completes.  Otherwise, the eellssee
+              _l_i_s_t  is executed, if present.  The exit status is the exit sta-
+              tus of the last command executed, or zero if no condition tested
+              true.

+       uunnttiill _l_i_s_t_-_1; ddoo _l_i_s_t_-_2; ddoonnee
+              The  wwhhiillee command continuously executes the list _l_i_s_t_-_2 as long
+              as the last command in the list _l_i_s_t_-_1 returns an exit status of
+              zero.   The uunnttiill command is identical to the wwhhiillee command, ex-
+              cept that the test is negated: _l_i_s_t_-_2 is executed as long as the
+              last command in _l_i_s_t_-_1 returns a non-zero exit status.  The exit
+              status of the wwhhiillee and uunnttiill commands is the exit status of the
+              last command executed in _l_i_s_t_-_2, or zero if none was executed.

+              ccoopprroocc [_N_A_M_E] _c_o_m_m_a_n_d [_r_e_d_i_r_e_c_t_i_o_n_s]
+
+       This creates a coprocess named _N_A_M_E.  _c_o_m_m_a_n_d may be  either  a  simple
+       command  or  a  compound command (see above).  _N_A_M_E is a shell variable
+       name.  If _N_A_M_E is not supplied, the default name is CCOOPPRROOCC.
+
+       The recommended form to use for a coprocess is
+
+              ccoopprroocc _N_A_M_E { _c_o_m_m_a_n_d [_r_e_d_i_r_e_c_t_i_o_n_s]; }
+
+       This form is recommended because simple commands result in  the  copro-
+       cess  always being named CCOOPPRROOCC, and it is simpler to use and more com-
+       plete than the other compound commands.
+
+       If _c_o_m_m_a_n_d is a compound command, _N_A_M_E is optional. The word  following
+       ccoopprroocc  determines whether that word is interpreted as a variable name:
+       it is interpreted as _N_A_M_E if it is not a reserved word that  introduces
+       a  compound  command.   If _c_o_m_m_a_n_d is a simple command, _N_A_M_E is not al-
+       lowed; this is to avoid confusion between _N_A_M_E and the  first  word  of
+       the simple command.
+
+       When  the  coprocess  is  executed, the shell creates an array variable
+       (see AArrrraayyss below) named _N_A_M_E in the context of  the  executing  shell.
+       The  standard  output  of _c_o_m_m_a_n_d is connected via a pipe to a file de-
+       scriptor in the executing shell, and that file descriptor  is  assigned
+       to _N_A_M_E[0].  The standard input of _c_o_m_m_a_n_d is connected via a pipe to a
+       file descriptor in the executing shell, and that file descriptor is as-
+       signed  to  _N_A_M_E[1].   This pipe is established before any redirections
+       specified by the command (see RREEDDIIRREECCTTIIOONN below).  The file descriptors
+       can  be  utilized as arguments to shell commands and redirections using
+       standard word expansions.  Other than those created to execute  command
+       and  process  substitutions,  the file descriptors are not available in
+       subshells.
+
+       The process ID of the shell spawned to execute the coprocess is  avail-
+       able  as  the value of the variable _N_A_M_E_PID.  The wwaaiitt builtin command
+       may be used to wait for the coprocess to terminate.
+
+       Since the coprocess is created as an asynchronous command,  the  ccoopprroocc
+       command  always  returns  success.  The return status of a coprocess is
+       the exit status of _c_o_m_m_a_n_d.
+
+   SShheellll FFuunnccttiioonn DDeeffiinniittiioonnss
+       A shell function is an object that is called like a simple command  and
+       executes  a  compound  command with a new set of positional parameters.
+       Shell functions are declared as follows:
+
+       _f_n_a_m_e () _c_o_m_p_o_u_n_d_-_c_o_m_m_a_n_d [_r_e_d_i_r_e_c_t_i_o_n]
+       ffuunnccttiioonn _f_n_a_m_e [()] _c_o_m_p_o_u_n_d_-_c_o_m_m_a_n_d [_r_e_d_i_r_e_c_t_i_o_n]
+              This defines a function named _f_n_a_m_e.  The reserved word ffuunnccttiioonn
+              is  optional.   If  the  ffuunnccttiioonn reserved word is supplied, the
+              parentheses are optional.  The _b_o_d_y of the function is the  com-
+              pound  command  _c_o_m_p_o_u_n_d_-_c_o_m_m_a_n_d  (see CCoommppoouunndd CCoommmmaannddss above).
+              That command is usually a _l_i_s_t of commands between { and },  but
+              may be any command listed under CCoommppoouunndd CCoommmmaannddss above.  If the
+              ffuunnccttiioonn reserved word is used, but the parentheses are not sup-
+              plied, the braces are recommended.  _c_o_m_p_o_u_n_d_-_c_o_m_m_a_n_d is executed
+              whenever _f_n_a_m_e is specified as the name  of  a  simple  command.
+              When in _p_o_s_i_x _m_o_d_e, _f_n_a_m_e must be a valid shell _n_a_m_e and may not
+              be the name of one of the POSIX _s_p_e_c_i_a_l  _b_u_i_l_t_i_n_s.   In  default
+              mode,  a  function name can be any unquoted shell word that does
+              not contain $$.  Any redirections (see RREEDDIIRREECCTTIIOONN below)  speci-
+              fied  when a function is defined are performed when the function
+              is executed.  The exit status of a function definition  is  zero
+              unless  a  syntax  error  occurs or a readonly function with the
+              same name already exists.  When executed, the exit status  of  a
+              function  is the exit status of the last command executed in the
+              body.  (See FFUUNNCCTTIIOONNSS below.)
+
+CCOOMMMMEENNTTSS
+       In a non-interactive shell, or an interactive shell in which the iinntteerr--
+       aaccttiivvee__ccoommmmeennttss  option  to  the  sshhoopptt  builtin  is enabled (see SSHHEELLLL
+       BBUUIILLTTIINN CCOOMMMMAANNDDSS below), a word beginning with ## causes that  word  and
+       all  remaining  characters  on that line to be ignored.  An interactive
+       shell without the iinntteerraaccttiivvee__ccoommmmeennttss option enabled  does  not  allow
+       comments.  The iinntteerraaccttiivvee__ccoommmmeennttss option is on by default in interac-
+       tive shells.
+
+QQUUOOTTIINNGG
+       _Q_u_o_t_i_n_g is used to remove the special meaning of certain characters  or
+       words  to  the shell.  Quoting can be used to disable special treatment
+       for special characters, to prevent reserved words from being recognized
+       as such, and to prevent parameter expansion.
+
+       Each  of  the _m_e_t_a_c_h_a_r_a_c_t_e_r_s listed above under DDEEFFIINNIITTIIOONNSS has special
+       meaning to the shell and must be quoted if it is to represent itself.
+
+       When the command history expansion facilities are being used (see  HHIISS--
+       TTOORRYY EEXXPPAANNSSIIOONN below), the _h_i_s_t_o_r_y _e_x_p_a_n_s_i_o_n character, usually !!, must
+       be quoted to prevent history expansion.
+
+       There are  three  quoting  mechanisms:  the  _e_s_c_a_p_e  _c_h_a_r_a_c_t_e_r,  single
+       quotes, and double quotes.
+
+       A  non-quoted  backslash (\\) is the _e_s_c_a_p_e _c_h_a_r_a_c_t_e_r.  It preserves the
+       literal value of the next character that follows, with the exception of
+       <newline>.   If a \\<newline> pair appears, and the backslash is not it-
+       self quoted, the \\<newline> is treated as a line continuation (that is,
+       it is removed from the input stream and effectively ignored).
+
+       Enclosing  characters  in  single quotes preserves the literal value of
+       each character within the quotes.  A single quote may not occur between
+       single quotes, even when preceded by a backslash.
+
+       Enclosing  characters  in  double quotes preserves the literal value of
+       all characters within the quotes, with the exception of $$, ``,  \\,  and,
+       when history expansion is enabled, !!.  When the shell is in _p_o_s_i_x _m_o_d_e,
+       the !! has no special meaning within double quotes,  even  when  history
+       expansion  is  enabled.   The  characters  $$ and `` retain their special
+       meaning within double quotes.  The backslash retains its special  mean-
+       ing  only when followed by one of the following characters: $$, ``, "", \\,
+       or <<nneewwlliinnee>>.  A double quote may be quoted  within  double  quotes  by
+       preceding  it  with a backslash.  If enabled, history expansion will be
+       performed unless an !!  appearing in double quotes is  escaped  using  a
+       backslash.  The backslash preceding the !!  is not removed.
+
+       The  special  parameters  **  and  @@ have special meaning when in double
+       quotes (see PPAARRAAMMEETTEERRSS below).
+
+       Character sequences of the form $$'_s_t_r_i_n_g'  are  treated  as  a  special
+       variant  of  single quotes.  The sequence expands to _s_t_r_i_n_g, with back-
+       slash-escaped characters in _s_t_r_i_n_g replaced as specified by the ANSI  C
+       standard.   Backslash escape sequences, if present, are decoded as fol-
+       lows:
+              \\aa     alert (bell)
+              \\bb     backspace
+              \\ee
+              \\EE     an escape character
+              \\ff     form feed
+              \\nn     new line
+              \\rr     carriage return
+              \\tt     horizontal tab
+              \\vv     vertical tab
+              \\\\     backslash
+              \\''     single quote
+              \\""     double quote
+              \\??     question mark
+              \\_n_n_n   the eight-bit character whose value is  the  octal  value
+                     _n_n_n (one to three octal digits)
+              \\xx_H_H   the  eight-bit  character  whose value is the hexadecimal
+                     value _H_H (one or two hex digits)
+              \\uu_H_H_H_H the Unicode (ISO/IEC 10646) character whose value is  the
+                     hexadecimal value _H_H_H_H (one to four hex digits)
+              \\UU_H_H_H_H_H_H_H_H
+                     the  Unicode (ISO/IEC 10646) character whose value is the
+                     hexadecimal value _H_H_H_H_H_H_H_H (one to eight hex digits)
+              \\cc_x    a control-_x character
+
+       The expanded result is single-quoted, as if the  dollar  sign  had  not
+       been present.
+
+       A double-quoted string preceded by a dollar sign ($$"_s_t_r_i_n_g") will cause
+       the string to be translated according to the current locale.  The  _g_e_t_-
+       _t_e_x_t  infrastructure  performs  the  lookup  and translation, using the
+       LLCC__MMEESSSSAAGGEESS, TTEEXXTTDDOOMMAAIINNDDIIRR, and TTEEXXTTDDOOMMAAIINN  shell  variables.   If  the
+       current  locale  is CC or PPOOSSIIXX, if there are no translations available,
+       or if the string is not translated, the dollar sign is  ignored.   This
+       is a form of double quoting, so the string remains double-quoted by de-
+       fault, whether or not it is translated  and  replaced.   If  the  nnooeexx--
+       ppaanndd__ttrraannssllaattiioonn  option is enabled using the sshhoopptt builtin, translated
+       strings are single-quoted instead of double-quoted.  See  the  descrip-
+       tion of sshhoopptt below under SSHHEELLLLBUILTINCCOOMMMMAANNDDSS.
+
+PPAARRAAMMEETTEERRSS
+       A  _p_a_r_a_m_e_t_e_r is an entity that stores values.  It can be a _n_a_m_e, a num-
+       ber, or one of the special characters listed below under SSppeecciiaall PPaarraamm--
+       eetteerrss.   A _v_a_r_i_a_b_l_e is a parameter denoted by a _n_a_m_e.  A variable has a
+       _v_a_l_u_e and zero or more _a_t_t_r_i_b_u_t_e_s.  Attributes are assigned  using  the
+       ddeeccllaarree builtin command (see ddeeccllaarree below in SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS).
+
+       A parameter is set if it has been assigned a value.  The null string is
+       a valid value.  Once a variable is set, it may be unset only  by  using
+       the uunnsseett builtin command (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below).
+
+       A _v_a_r_i_a_b_l_e may be assigned to by a statement of the form
+
+              _n_a_m_e=[_v_a_l_u_e]
+
+       If  _v_a_l_u_e  is not given, the variable is assigned the null string.  All
+       _v_a_l_u_e_s undergo tilde expansion, parameter and variable expansion,  com-
+       mand  substitution, arithmetic expansion, and quote removal (see EEXXPPAANN--
+       SSIIOONN below).  If the variable has its iinntteeggeerr attribute set, then _v_a_l_u_e
+       is evaluated as an arithmetic expression even if the $((...)) expansion
+       is not used (see AArriitthhmmeettiicc EExxppaannssiioonn below).  Word splitting and path-
+       name  expansion  are not performed.  Assignment statements may also ap-
+       pear as arguments to the aalliiaass, ddeeccllaarree, ttyyppeesseett, eexxppoorrtt, rreeaaddoonnllyy, and
+       llooccaall  builtin  commands  (_d_e_c_l_a_r_a_t_i_o_n  commands).  When in _p_o_s_i_x _m_o_d_e,
+       these builtins may appear in a command after one or more  instances  of
+       the ccoommmmaanndd builtin and retain these assignment statement properties.
+
+       In  the context where an assignment statement is assigning a value to a
+       shell variable or array index, the += operator can be used to append to
+       or  add  to  the variable's previous value.  This includes arguments to
+       builtin commands such as  ddeeccllaarree  that  accept  assignment  statements
+       (_d_e_c_l_a_r_a_t_i_o_n commands).  When += is applied to a variable for which the
+       iinntteeggeerr attribute has been set, _v_a_l_u_e is evaluated as an arithmetic ex-
+       pression and added to the variable's current value, which is also eval-
+       uated.  When += is applied to an array variable using compound  assign-
+       ment  (see  AArrrraayyss  below), the variable's value is not unset (as it is
+       when using =), and new values are appended to the  array  beginning  at
+       one  greater  than  the  array's  maximum index (for indexed arrays) or
+       added as additional key-value pairs in an associative array.  When  ap-
+       plied  to  a  string-valued variable, _v_a_l_u_e is expanded and appended to
+       the variable's value.
+
+       A variable can be assigned the _n_a_m_e_r_e_f attribute using the --nn option to
+       the  ddeeccllaarree or llooccaall builtin commands (see the descriptions of ddeeccllaarree
+       and llooccaall below) to create a _n_a_m_e_r_e_f, or a reference to  another  vari-
+       able.   This  allows  variables to be manipulated indirectly.  Whenever
+       the nameref variable is referenced, assigned to, unset, or has its  at-
+       tributes  modified  (other than using or changing the _n_a_m_e_r_e_f attribute
+       itself), the operation is actually performed on the variable  specified
+       by  the  nameref  variable's  value.  A nameref is commonly used within
+       shell functions to refer to a variable whose name is passed as an argu-
+       ment  to the function.  For instance, if a variable name is passed to a
+       shell function as its first argument, running
+              declare -n ref=$1
+       inside the function creates a nameref variable rreeff whose value  is  the
+       variable name passed as the first argument.  References and assignments
+       to rreeff, and changes to its attributes, are treated as  references,  as-
+       signments,  and  attribute modifications to the variable whose name was
+       passed as $$11.  If the control variable in a ffoorr loop  has  the  nameref
+       attribute,  the  list  of words can be a list of shell variables, and a
+       name reference will be established for each word in the list, in  turn,
+       when the loop is executed.  Array variables cannot be given the nnaammeerreeff
+       attribute.  However, nameref variables can  reference  array  variables
+       and  subscripted  array  variables.  Namerefs can be unset using the --nn
+       option to the uunnsseett builtin.  Otherwise, if uunnsseett is executed with  the
+       name  of  a nameref variable as an argument, the variable referenced by
+       the nameref variable will be unset.
+
+   PPoossiittiioonnaall PPaarraammeetteerrss
+       A _p_o_s_i_t_i_o_n_a_l _p_a_r_a_m_e_t_e_r is a parameter denoted by one  or  more  digits,
+       other than the single digit 0.  Positional parameters are assigned from
+       the shell's arguments when it is invoked, and may be  reassigned  using
+       the  sseett builtin command.  Positional parameters may not be assigned to
+       with assignment statements.  The positional parameters are  temporarily
+       replaced when a shell function is executed (see FFUUNNCCTTIIOONNSS below).
+
+       When  a  positional parameter consisting of more than a single digit is
+       expanded, it must be enclosed in braces (see EEXXPPAANNSSIIOONN below).
+
+   SSppeecciiaall PPaarraammeetteerrss
+       The shell treats several parameters specially.   These  parameters  may
+       only be referenced; assignment to them is not allowed.
+       **      Expands  to  the positional parameters, starting from one.  When
+              the expansion is not within double quotes, each  positional  pa-
+              rameter  expands  to  a  separate word.  In contexts where it is
+              performed, those words are subject to further word splitting and
+              pathname  expansion.   When  the  expansion occurs within double
+              quotes, it expands to a single word with the value of  each  pa-
+              rameter  separated  by  the  first  character of the IIFFSS special
+              variable.  That is, "$$**" is equivalent to "$$11_c$$22_c......",  where  _c
+              is the first character of the value of the IIFFSS variable.  If IIFFSS
+              is unset, the parameters are separated by  spaces.   If  IIFFSS  is
+              null, the parameters are joined without intervening separators.
+       @@      Expands  to  the  positional  parameters, starting from one.  In
+              contexts where word splitting is performed,  this  expands  each
+              positional  parameter  to  a separate word; if not within double
+              quotes, these words are subject to word splitting.  In  contexts
+              where  word splitting is not performed, this expands to a single
+              word with each positional parameter separated by a space.   When
+              the  expansion  occurs  within double quotes, each parameter ex-
+              pands to a separate word.  That is, "$$@@" is equivalent  to  "$$11"
+              "$$22"  ...   If the double-quoted expansion occurs within a word,
+              the expansion of the first parameter is joined with  the  begin-
+              ning  part  of  the original word, and the expansion of the last
+              parameter is joined with the last part  of  the  original  word.
+              When  there  are no positional parameters, "$$@@" and $$@@ expand to
+              nothing (i.e., they are removed).
+       ##      Expands to the number of positional parameters in decimal.
+       ??      Expands to the exit status of the most recently  executed  fore-
+              ground pipeline.
+       --      Expands  to  the  current option flags as specified upon invoca-
+              tion, by the sseett builtin command, or those set by the shell  it-
+              self (such as the --ii option).
+       $$      Expands  to  the  process ID of the shell. In a subshell, it ex-
+              pands to the process ID of the current shell, not the subshell.
+       !!      Expands to the process ID of the job most recently  placed  into
+              the  background,  whether executed as an asynchronous command or
+              using the bbgg builtin (see JJOOBB CCOONNTTRROOLL below).
+       00      Expands to the name of the shell or shell script.  This  is  set
+              at shell initialization.  If bbaasshh is invoked with a file of com-
+              mands, $$00 is set to the name of that file.  If bbaasshh  is  started
+              with  the  --cc option, then $$00 is set to the first argument after
+              the string to be executed, if one is present.  Otherwise, it  is
+              set  to  the  filename used to invoke bbaasshh, as given by argument
+              zero.
+
+   SShheellll VVaarriiaabblleess
+       The following variables are set by the shell:
+
+       __      At shell startup, set to the pathname used to invoke  the  shell
+              or  shell  script being executed as passed in the environment or
+              argument list.  Subsequently, expands to the  last  argument  to
+              the  previous  simple  command executed in the foreground, after
+              expansion.  Also set to the full pathname used  to  invoke  each
+              command  executed and placed in the environment exported to that
+              command.  When checking mail, this parameter holds the  name  of
+              the mail file currently being checked.
+       BBAASSHH   Expands  to  the  full  filename used to invoke this instance of
+              bbaasshh.
+       BBAASSHHOOPPTTSS
+              A colon-separated list of enabled shell options.  Each  word  in
+              the  list  is  a  valid  argument for the --ss option to the sshhoopptt
+              builtin command (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below).  The options
+              appearing  in  BBAASSHHOOPPTTSS  are  those reported as _o_n by sshhoopptt.  If
+              this variable is in the environment when bbaasshh  starts  up,  each
+              shell  option  in  the  list  will be enabled before reading any
+              startup files.  This variable is read-only.
+       BBAASSHHPPIIDD
+              Expands to the process ID of the  current  bbaasshh  process.   This
+              differs  from  $$$$ under certain circumstances, such as subshells
+              that do not require bbaasshh to be re-initialized.   Assignments  to
+              BBAASSHHPPIIDD  have no effect.  If BBAASSHHPPIIDD is unset, it loses its spe-
+              cial properties, even if it is subsequently reset.
+       BBAASSHH__AALLIIAASSEESS
+              An associative array variable whose members  correspond  to  the
+              internal  list  of  aliases  as maintained by the aalliiaass builtin.
+              Elements added to this array appear in the alias list;  however,
+              unsetting  array elements currently does not cause aliases to be
+              removed from the alias list.  If BBAASSHH__AALLIIAASSEESS is unset, it loses
+              its special properties, even if it is subsequently reset.
+       BBAASSHH__AARRGGCC
+              An  array  variable whose values are the number of parameters in
+              each frame of the current bbaasshh execution call stack.  The number
+              of  parameters  to  the  current  subroutine  (shell function or
+              script executed with .. or ssoouurrccee) is at the top  of  the  stack.
+              When  a  subroutine is executed, the number of parameters passed
+              is pushed onto BBAASSHH__AARRGGCC.  The shell sets BBAASSHH__AARRGGCC only when in
+              extended debugging mode (see the description of the eexxttddeebbuugg op-
+              tion to the sshhoopptt builtin below).  Setting  eexxttddeebbuugg  after  the
+              shell has started to execute a script, or referencing this vari-
+              able when eexxttddeebbuugg is not set, may result in  inconsistent  val-
+              ues.
+       BBAASSHH__AARRGGVV
+              An  array  variable containing all of the parameters in the cur-
+              rent bbaasshh execution call stack.  The final parameter of the last
+              subroutine  call is at the top of the stack; the first parameter
+              of the initial call is at the bottom.  When a subroutine is exe-
+              cuted,  the  parameters supplied are pushed onto BBAASSHH__AARRGGVV.  The
+              shell sets BBAASSHH__AARRGGVV only when in extended debugging  mode  (see
+              the  description of the eexxttddeebbuugg option to the sshhoopptt builtin be-
+              low).  Setting eexxttddeebbuugg after the shell has started to execute a
+              script,  or  referencing this variable when eexxttddeebbuugg is not set,
+              may result in inconsistent values.
+       BBAASSHH__AARRGGVV00
+              When referenced, this variable expands to the name of the  shell
+              or shell script (identical to $$00; see the description of special
+              parameter 0 above).  Assignment to BBAASSHH__AARRGGVV00 causes  the  value
+              assigned  to also be assigned to $$00.  If BBAASSHH__AARRGGVV00 is unset, it
+              loses its special properties, even if it is subsequently reset.
+       BBAASSHH__CCMMDDSS
+              An associative array variable whose members  correspond  to  the
+              internal  hash  table  of  commands  as  maintained  by the hhaasshh
+              builtin.  Elements added to this array appear in the hash table;
+              however,  unsetting array elements currently does not cause com-
+              mand names to be removed from the hash table.  If  BBAASSHH__CCMMDDSS  is
+              unset,  it  loses  its  special properties, even if it is subse-
+              quently reset.
+       BBAASSHH__CCOOMMMMAANNDD
+              The command currently being executed or about  to  be  executed,
+              unless the shell is executing a command as the result of a trap,
+              in which case it is the command executing at  the  time  of  the
+              trap.   If  BBAASSHH__CCOOMMMMAANNDD  is unset, it loses its special proper-
+              ties, even if it is subsequently reset.
+       BBAASSHH__EEXXEECCUUTTIIOONN__SSTTRRIINNGG
+              The command argument to the --cc invocation option.
+       BBAASSHH__LLIINNEENNOO
+              An array variable whose members are the line numbers  in  source
+              files  where  each corresponding member of FFUUNNCCNNAAMMEE was invoked.
+              $${{BBAASSHH__LLIINNEENNOO[[_$_i]]}}  is  the  line  number  in  the  source  file
+              ($${{BBAASSHH__SSOOUURRCCEE[[_$_i_+_1]]}})  where  $${{FFUUNNCCNNAAMMEE[[_$_i]]}}  was  called  (or
+              $${{BBAASSHH__LLIINNEENNOO[[_$_i_-_1]]}} if referenced within  another  shell  func-
+              tion).  Use LLIINNEENNOO to obtain the current line number.
+       BBAASSHH__LLOOAADDAABBLLEESS__PPAATTHH
+              A  colon-separated  list of directories in which the shell looks
+              for dynamically loadable builtins specified by the  eennaabbllee  com-
+              mand.
+       BBAASSHH__RREEMMAATTCCHH
+              An  array  variable  whose members are assigned by the ==~~ binary
+              operator to the [[[[ conditional command.  The element with  index
+              0  is  the portion of the string matching the entire regular ex-
+              pression.  The element with index _n is the portion of the string
+              matching the _nth parenthesized subexpression.
+       BBAASSHH__SSOOUURRCCEE
+              An  array  variable whose members are the source filenames where
+              the corresponding shell function names  in  the  FFUUNNCCNNAAMMEE  array
+              variable are defined.  The shell function $${{FFUUNNCCNNAAMMEE[[_$_i]]}} is de-
+              fined  in  the   file   $${{BBAASSHH__SSOOUURRCCEE[[_$_i]]}}   and   called   from
+              $${{BBAASSHH__SSOOUURRCCEE[[_$_i_+_1]]}}.
+       BBAASSHH__SSUUBBSSHHEELLLL
+              Incremented  by one within each subshell or subshell environment
+              when the shell begins executing in that environment.   The  ini-
+              tial  value  is 0.  If BBAASSHH__SSUUBBSSHHEELLLL is unset, it loses its spe-
+              cial properties, even if it is subsequently reset.
+       BBAASSHH__VVEERRSSIINNFFOO
+              A readonly array variable whose members hold version information
+              for  this  instance  of  bbaasshh.  The values assigned to the array
+              members are as follows:
+              BBAASSHH__VVEERRSSIINNFFOO[[0]]        The major version number (the _r_e_l_e_a_s_e).
+              BBAASSHH__VVEERRSSIINNFFOO[[1]]        The minor version number (the _v_e_r_s_i_o_n).
+              BBAASSHH__VVEERRSSIINNFFOO[[2]]        The patch level.
+              BBAASSHH__VVEERRSSIINNFFOO[[3]]        The build version.
+              BBAASSHH__VVEERRSSIINNFFOO[[4]]        The release status (e.g., _b_e_t_a_1).
+              BBAASSHH__VVEERRSSIINNFFOO[[5]]        The value of MMAACCHHTTYYPPEE.
+       BBAASSHH__VVEERRSSIIOONN
+              Expands to a string describing the version of this  instance  of
+              bbaasshh.
+       CCOOMMPP__CCWWOORRDD
+              An  index  into $${{CCOOMMPP__WWOORRDDSS}} of the word containing the current
+              cursor position.  This variable is available only in shell func-
+              tions  invoked  by  the  programmable completion facilities (see
+              PPrrooggrraammmmaabbllee CCoommpplleettiioonn below).
+       CCOOMMPP__KKEEYY
+              The key (or final key of a key sequence) used to invoke the cur-
+              rent completion function.
+       CCOOMMPP__LLIINNEE
+              The  current  command  line.  This variable is available only in
+              shell functions and external commands invoked  by  the  program-
+              mable completion facilities (see PPrrooggrraammmmaabbllee CCoommpplleettiioonn below).
+       CCOOMMPP__PPOOIINNTT
+              The  index of the current cursor position relative to the begin-
+              ning of the current command.  If the current cursor position  is
+              at the end of the current command, the value of this variable is
+              equal to $${{##CCOOMMPP__LLIINNEE}}.  This  variable  is  available  only  in
+              shell  functions  and  external commands invoked by the program-
+              mable completion facilities (see PPrrooggrraammmmaabbllee CCoommpplleettiioonn below).
+       CCOOMMPP__TTYYPPEE
+              Set to an integer value corresponding to the type of  completion
+              attempted  that  caused a completion function to be called: _T_A_B,
+              for normal completion, _?, for listing completions after  succes-
+              sive  tabs,  _!, for listing alternatives on partial word comple-
+              tion, _@, to list completions if the word is not  unmodified,  or
+              _%,  for  menu  completion.   This  variable is available only in
+              shell functions and external commands invoked  by  the  program-
+              mable completion facilities (see PPrrooggrraammmmaabbllee CCoommpplleettiioonn below).
+       CCOOMMPP__WWOORRDDBBRREEAAKKSS
+              The  set  of characters that the rreeaaddlliinnee library treats as word
+              separators when performing word completion.  If  CCOOMMPP__WWOORRDDBBRREEAAKKSS
+              is  unset, it loses its special properties, even if it is subse-
+              quently reset.
+       CCOOMMPP__WWOORRDDSS
+              An array variable (see AArrrraayyss below) consisting of the  individ-
+              ual  words  in the current command line.  The line is split into
+              words as rreeaaddlliinnee would split it, using CCOOMMPP__WWOORRDDBBRREEAAKKSS  as  de-
+              scribed  above.   This variable is available only in shell func-
+              tions invoked by the  programmable  completion  facilities  (see
+              PPrrooggrraammmmaabbllee CCoommpplleettiioonn below).
+       CCOOPPRROOCC An  array  variable  (see AArrrraayyss below) created to hold the file
+              descriptors for output from and input to  an  unnamed  coprocess
+              (see CCoopprroocceesssseess above).
+       DDIIRRSSTTAACCKK
+              An array variable (see AArrrraayyss below) containing the current con-
+              tents of the directory stack.  Directories appear in  the  stack
+              in  the order they are displayed by the ddiirrss builtin.  Assigning
+              to members of this array variable may be used to modify directo-
+              ries  already in the stack, but the ppuusshhdd and ppooppdd builtins must
+              be used to add and remove directories.  Assignment to this vari-
+              able  will not change the current directory.  If DDIIRRSSTTAACCKK is un-
+              set, it loses its special properties, even if it is subsequently
+              reset.
+       EEPPOOCCHHRREEAALLTTIIMMEE
+              Each time this parameter is referenced, it expands to the number
+              of seconds since the Unix Epoch  (see  _t_i_m_e(3))  as  a  floating
+              point  value  with  micro-second  granularity.   Assignments  to
+              EEPPOOCCHHRREEAALLTTIIMMEE are ignored.  If EEPPOOCCHHRREEAALLTTIIMMEE is unset, it  loses
+              its special properties, even if it is subsequently reset.
+       EEPPOOCCHHSSEECCOONNDDSS
+              Each time this parameter is referenced, it expands to the number
+              of seconds since the Unix Epoch (see _t_i_m_e(3)).   Assignments  to
+              EEPPOOCCHHSSEECCOONNDDSS  are  ignored.   If EEPPOOCCHHSSEECCOONNDDSS is unset, it loses
+              its special properties, even if it is subsequently reset.
+       EEUUIIDD   Expands to the effective user ID of the current  user,  initial-
+              ized at shell startup.  This variable is readonly.
+       FFUUNNCCNNAAMMEE
+              An  array  variable  containing the names of all shell functions
+              currently in the execution call stack.  The element with index 0
+              is the name of any currently-executing shell function.  The bot-
+              tom-most element (the one with the  highest  index)  is  "main".
+              This  variable  exists  only when a shell function is executing.
+              Assignments to FFUUNNCCNNAAMMEE have no effect.  If FFUUNNCCNNAAMMEE  is  unset,
+              it  loses its special properties, even if it is subsequently re-
+              set.
+
+              This variable can be  used  with  BBAASSHH__LLIINNEENNOO  and  BBAASSHH__SSOOUURRCCEE.
+              Each   element   of   FFUUNNCCNNAAMMEE  has  corresponding  elements  in
+              BBAASSHH__LLIINNEENNOO and BBAASSHH__SSOOUURRCCEE to describe the call stack.  For in-
+              stance,    $${{FFUUNNCCNNAAMMEE[[_$_i]]}}    was    called    from   the   file
+              $${{BBAASSHH__SSOOUURRCCEE[[_$_i_+_1]]}} at  line  number  $${{BBAASSHH__LLIINNEENNOO[[_$_i]]}}.   The
+              ccaalllleerr builtin displays the current call stack using this infor-
+              mation.
+       GGRROOUUPPSS An array variable containing the list of  groups  of  which  the
+              current user is a member.  Assignments to GGRROOUUPPSS have no effect.
+              If GGRROOUUPPSS is unset, it loses its special properties, even if  it
+              is subsequently reset.
+       HHIISSTTCCMMDD
+              The history number, or index in the history list, of the current
+              command.  Assignments to HHIISSTTCCMMDD are ignored.  If HHIISSTTCCMMDD is un-
+              set, it loses its special properties, even if it is subsequently
+              reset.
+       HHOOSSTTNNAAMMEE
+              Automatically set to the name of the current host.
+       HHOOSSTTTTYYPPEE
+              Automatically set to a string that uniquely describes  the  type
+              of  machine  on which bbaasshh is executing.  The default is system-
+              dependent.
+       LLIINNEENNOO Each time this parameter is referenced, the shell substitutes  a
+              decimal  number  representing the current sequential line number
+              (starting with 1) within a script or function.  When  not  in  a
+              script  or  function, the value substituted is not guaranteed to
+              be meaningful.  If LLIINNEENNOO is unset, it loses its special proper-
+              ties, even if it is subsequently reset.
+       MMAACCHHTTYYPPEE
+              Automatically  set  to  a string that fully describes the system
+              type on which bbaasshh is executing, in the  standard  GNU  _c_p_u_-_c_o_m_-
+              _p_a_n_y_-_s_y_s_t_e_m format.  The default is system-dependent.
+       MMAAPPFFIILLEE
+              An  array  variable  (see AArrrraayyss below) created to hold the text
+              read by the mmaappffiillee builtin when no variable name is supplied.
+       OOLLDDPPWWDD The previous working directory as set by the ccdd command.
+       OOPPTTAARRGG The value of the last option argument processed by  the  ggeettooppttss
+              builtin command (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below).
+       OOPPTTIINNDD The  index  of  the next argument to be processed by the ggeettooppttss
+              builtin command (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below).
+       OOSSTTYYPPEE Automatically set to a string that describes the operating  sys-
+              tem  on  which  bbaasshh is executing.  The default is system-depen-
+              dent.
+       PPIIPPEESSTTAATTUUSS
+              An array variable (see AArrrraayyss below) containing a list  of  exit
+              status  values  from the processes in the most-recently-executed
+              foreground pipeline (which may contain only a single command).
+       PPPPIIDD   The process ID of the shell's parent.  This  variable  is  read-
+              only.
+       PPWWDD    The current working directory as set by the ccdd command.
+       RRAANNDDOOMM Each  time  this parameter is referenced, it expands to a random
+              integer between 0 and 32767.  Assigning a value to  RRAANNDDOOMM  ini-
+              tializes  (seeds)  the sequence of random numbers.  If RRAANNDDOOMM is
+              unset, it loses its special properties, even  if  it  is  subse-
+              quently reset.
+       RREEAADDLLIINNEE__AARRGGUUMMEENNTT
+              Any  numeric  argument  given to a readline command that was de-
+              fined using "bind -x" (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below) when it
+              was invoked.
+       RREEAADDLLIINNEE__LLIINNEE
+              The contents of the rreeaaddlliinnee line buffer, for use with "bind -x"
+              (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below).
+       RREEAADDLLIINNEE__MMAARRKK
+              The position of the mark (saved insertion point) in the rreeaaddlliinnee
+              line  buffer, for use with "bind -x" (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS
+              below).  The characters between the insertion point and the mark
+              are often called the _r_e_g_i_o_n.
+       RREEAADDLLIINNEE__PPOOIINNTT
+              The position of the insertion point in the rreeaaddlliinnee line buffer,
+              for use with "bind -x" (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below).
+       RREEPPLLYY  Set to the line of input read by the rreeaadd builtin  command  when
+              no arguments are supplied.
+       SSEECCOONNDDSS
+              Each time this parameter is referenced, it expands to the number
+              of seconds since shell invocation.  If a value  is  assigned  to
+              SSEECCOONNDDSS,  the  value  returned upon subsequent references is the
+              number of seconds since the assignment plus the value  assigned.
+              The  number  of seconds at shell invocation and the current time
+              are always determined by querying the system clock.  If  SSEECCOONNDDSS
+              is  unset, it loses its special properties, even if it is subse-
+              quently reset.
+       SSHHEELLLLOOPPTTSS
+              A colon-separated list of enabled shell options.  Each  word  in
+              the  list  is  a  valid  argument  for  the --oo option to the sseett
+              builtin command (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below).  The options
+              appearing  in  SSHHEELLLLOOPPTTSS are those reported as _o_n by sseett --oo.  If
+              this variable is in the environment when bbaasshh  starts  up,  each
+              shell  option  in  the  list  will be enabled before reading any
+              startup files.  This variable is read-only.
+       SSHHLLVVLL  Incremented by one each time an instance of bbaasshh is started.
+       SSRRAANNDDOOMM
+              This variable expands to a 32-bit pseudo-random number each time
+              it  is  referenced. The random number generator is not linear on
+              systems that support /dev/urandom or  _a_r_c_4_r_a_n_d_o_m,  so  each  re-
+              turned  number  has no relationship to the numbers preceding it.
+              The random number generator cannot be seeded, so assignments  to
+              this variable have no effect.  If SSRRAANNDDOOMM is unset, it loses its
+              special properties, even if it is subsequently reset.
+       UUIIDD    Expands to the user ID of the current user, initialized at shell
+              startup.  This variable is readonly.
+
+       The following variables are used by the shell.  In some cases, bbaasshh as-
+       signs a default value to a variable; these cases are noted below.
+
+       BBAASSHH__CCOOMMPPAATT
+              The value is used to set the shell's compatibility  level.   See
+              SSHHEELLLL  CCOOMMPPAATTIIBBIILLIITTYY MMOODDEE below for a description of the various
+              compatibility levels and their effects.  The value may be a dec-
+              imal  number  (e.g., 4.2) or an integer (e.g., 42) corresponding
+              to the desired compatibility level.  If BBAASSHH__CCOOMMPPAATT is unset  or
+              set  to  the empty string, the compatibility level is set to the
+              default for the current version.  If BBAASSHH__CCOOMMPPAATT  is  set  to  a
+              value  that  is  not  one of the valid compatibility levels, the
+              shell prints an error message and sets the  compatibility  level
+              to the default for the current version.  The valid values corre-
+              spond to the compatibility levels described  below  under  SSHHEELLLL
+              CCOOMMPPAATTIIBBIILLIITTYY  MMOODDEE.   For  example, 4.2 and 42 are valid values
+              that correspond to the ccoommppaatt4422 sshhoopptt option and set the compat-
+              ibility level to 42.  The current version is also a valid value.
+       BBAASSHH__EENNVV
+              If  this parameter is set when bbaasshh is executing a shell script,
+              its value is interpreted as a filename  containing  commands  to
+              initialize the shell, as in _~_/_._b_a_s_h_r_c.  The value of BBAASSHH__EENNVV is
+              subjected to  parameter  expansion,  command  substitution,  and
+              arithmetic  expansion  before  being  interpreted as a filename.
+              PPAATTHH is not used to search for the resultant filename.
+       BBAASSHH__XXTTRRAACCEEFFDD
+              If set to an integer corresponding to a valid  file  descriptor,
+              bbaasshh  will  write  the trace output generated when _s_e_t _-_x is en-
+              abled to that file descriptor.  The file  descriptor  is  closed
+              when  BBAASSHH__XXTTRRAACCEEFFDD is unset or assigned a new value.  Unsetting
+              BBAASSHH__XXTTRRAACCEEFFDD or assigning it the empty string causes the  trace
+              output  to  be  sent  to  the standard error.  Note that setting
+              BBAASSHH__XXTTRRAACCEEFFDD to 2 (the standard error file descriptor) and then
+              unsetting it will result in the standard error being closed.
+       CCDDPPAATTHH The  search  path for the ccdd command.  This is a colon-separated
+              list of directories in which the shell looks for destination di-
+              rectories  specified  by  the  ccdd  command.   A  sample value is
+              ".:~:/usr".
+       CCHHIILLDD__MMAAXX
+              Set the number of exited child status values for  the  shell  to
+              remember.   Bash will not allow this value to be decreased below
+              a POSIX-mandated minimum, and there is  a  maximum  value  (cur-
+              rently  8192)  that  this  may not exceed.  The minimum value is
+              system-dependent.
+       CCOOLLUUMMNNSS
+              Used by the sseelleecctt compound command to  determine  the  terminal
+              width  when  printing selection lists.  Automatically set if the
+              cchheecckkwwiinnssiizzee option is enabled or in an interactive  shell  upon
+              receipt of a SSIIGGWWIINNCCHH.
+       CCOOMMPPRREEPPLLYY
+              An array variable from which bbaasshh reads the possible completions
+              generated by a shell function invoked by the  programmable  com-
+              pletion  facility (see PPrrooggrraammmmaabbllee CCoommpplleettiioonn below).  Each ar-
+              ray element contains one possible completion.
+       EEMMAACCSS  If bbaasshh finds this variable in the environment  when  the  shell
+              starts  with  value "t", it assumes that the shell is running in
+              an Emacs shell buffer and disables line editing.
+       EENNVV    Expanded and executed  similarly  to  BBAASSHH__EENNVV  (see  IINNVVOOCCAATTIIOONN
+              above) when an interactive shell is invoked in _p_o_s_i_x _m_o_d_e.
+       EEXXEECCIIGGNNOORREE
+              A  colon-separated list of shell patterns (see PPaatttteerrnn MMaattcchhiinngg)
+              defining the list of filenames to be ignored by  command  search
+              using  PPAATTHH.  Files whose full pathnames match one of these pat-
+              terns are not considered executable files for  the  purposes  of
+              completion and command execution via PPAATTHH lookup.  This does not
+              affect the behavior of the [[, tteesstt, and [[[[ commands.  Full path-
+              names  in  the command hash table are not subject to EEXXEECCIIGGNNOORREE.
+              Use this variable to ignore shared library files that  have  the
+              executable  bit  set, but are not executable files.  The pattern
+              matching honors the setting of the eexxttgglloobb shell option.
+       FFCCEEDDIITT The default editor for the ffcc builtin command.
+       FFIIGGNNOORREE
+              A colon-separated list of suffixes  to  ignore  when  performing
+              filename completion (see RREEAADDLLIINNEE below).  A filename whose suf-
+              fix matches one of the entries in FFIIGGNNOORREE is excluded  from  the
+              list of matched filenames.  A sample value is ".o:~".
+       FFUUNNCCNNEESSTT
+              If  set  to  a  numeric  value greater than 0, defines a maximum
+              function nesting level.  Function invocations that  exceed  this
+              nesting level will cause the current command to abort.
+       GGLLOOBBIIGGNNOORREE
+              A  colon-separated  list  of  patterns  defining the set of file
+              names to be ignored by  pathname  expansion.   If  a  file  name
+              matched  by a pathname expansion pattern also matches one of the
+              patterns in GGLLOOBBIIGGNNOORREE, it is removed from the list of matches.
+       HHIISSTTCCOONNTTRROOLL
+              A colon-separated list of values controlling  how  commands  are
+              saved  on  the history list.  If the list of values includes _i_g_-
+              _n_o_r_e_s_p_a_c_e, lines which begin with  a  ssppaaccee  character  are  not
+              saved  in  the history list.  A value of _i_g_n_o_r_e_d_u_p_s causes lines
+              matching the previous history entry to not be saved.  A value of
+              _i_g_n_o_r_e_b_o_t_h is shorthand for _i_g_n_o_r_e_s_p_a_c_e and _i_g_n_o_r_e_d_u_p_s.  A value
+              of _e_r_a_s_e_d_u_p_s causes all previous lines matching the current line
+              to  be  removed from the history list before that line is saved.
+              Any value not in the above list is ignored.  If  HHIISSTTCCOONNTTRROOLL  is
+              unset,  or does not include a valid value, all lines read by the
+              shell parser are saved on the history list, subject to the value
+              of  HHIISSTTIIGGNNOORREE.  The second and subsequent lines of a multi-line
+              compound command are not tested, and are added  to  the  history
+              regardless of the value of HHIISSTTCCOONNTTRROOLL.
+       HHIISSTTFFIILLEE
+              The name of the file in which command history is saved (see HHIISS--
+              TTOORRYY below).  The default value is _~_/_._b_a_s_h___h_i_s_t_o_r_y.   If  unset,
+              the command history is not saved when a shell exits.
+       HHIISSTTFFIILLEESSIIZZEE
+              The maximum number of lines contained in the history file.  When
+              this variable is assigned a value, the  history  file  is  trun-
+              cated,  if  necessary,  to  contain  no more than that number of
+              lines by removing the oldest entries.  The history file is  also
+              truncated  to this size after writing it when a shell exits.  If
+              the value is 0, the history file  is  truncated  to  zero  size.
+              Non-numeric  values  and  numeric  values less than zero inhibit
+              truncation.  The shell sets the default value to  the  value  of
+              HHIISSTTSSIIZZEE after reading any startup files.
+       HHIISSTTIIGGNNOORREE
+              A  colon-separated list of patterns used to decide which command
+              lines should be saved on the history list.  Each pattern is  an-
+              chored  at the beginning of the line and must match the complete
+              line (no implicit `**' is  appended).   Each  pattern  is  tested
+              against  the  line after the checks specified by HHIISSTTCCOONNTTRROOLL are
+              applied.  In addition to the normal shell pattern matching char-
+              acters,  `&&'  matches the previous history line.  `&&' may be es-
+              caped using a backslash; the backslash  is  removed  before  at-
+              tempting  a  match.  The second and subsequent lines of a multi-
+              line compound command are not tested, and are added to the  his-
+              tory  regardless of the value of HHIISSTTIIGGNNOORREE.  The pattern match-
+              ing honors the setting of the eexxttgglloobb shell option.
+       HHIISSTTSSIIZZEE
+              The number of commands to remember in the command  history  (see
+              HHIISSTTOORRYY  below).   If  the value is 0, commands are not saved in
+              the history list.  Numeric values less than zero result in every
+              command  being  saved  on  the history list (there is no limit).
+              The shell sets the  default  value  to  500  after  reading  any
+              startup files.
+       HHIISSTTTTIIMMEEFFOORRMMAATT
+              If  this  variable  is  set and not null, its value is used as a
+              format string for _s_t_r_f_t_i_m_e(3) to print the time stamp associated
+              with  each  history  entry displayed by the hhiissttoorryy builtin.  If
+              this variable is set, time stamps are  written  to  the  history
+              file  so they may be preserved across shell sessions.  This uses
+              the history comment character  to  distinguish  timestamps  from
+              other history lines.
+       HHOOMMEE   The home directory of the current user; the default argument for
+              the ccdd builtin command.  The value of this variable is also used
+              when performing tilde expansion.
+       HHOOSSTTFFIILLEE
+              Contains  the  name  of  a file in the same format as _/_e_t_c_/_h_o_s_t_s
+              that should be read when the shell needs to complete a hostname.
+              The  list  of possible hostname completions may be changed while
+              the shell is running; the next time hostname completion  is  at-
+              tempted  after  the  value is changed, bbaasshh adds the contents of
+              the new file to the existing list.  If HHOOSSTTFFIILLEE is set, but  has
+              no  value,  or  does  not name a readable file, bbaasshh attempts to
+              read _/_e_t_c_/_h_o_s_t_s to obtain the list of possible hostname  comple-
+              tions.  When HHOOSSTTFFIILLEE is unset, the hostname list is cleared.
+       IIFFSS    The _I_n_t_e_r_n_a_l _F_i_e_l_d _S_e_p_a_r_a_t_o_r that is used for word splitting af-
+              ter expansion and to  split  lines  into  words  with  the  rreeaadd
+              builtin  command.   The  default  value  is  ``<space><tab><new-
+              line>''.
+       IIGGNNOORREEEEOOFF
+              Controls the action of an interactive shell on receipt of an EEOOFF
+              character as the sole input.  If set, the value is the number of
+              consecutive EEOOFF characters which must  be  typed  as  the  first
+              characters  on an input line before bbaasshh exits.  If the variable
+              exists but does not have a numeric value, or has no  value,  the
+              default  value  is  10.  If it does not exist, EEOOFF signifies the
+              end of input to the shell.
+       IINNPPUUTTRRCC
+              The filename for the rreeaaddlliinnee startup file, overriding  the  de-
+              fault of _~_/_._i_n_p_u_t_r_c (see RREEAADDLLIINNEE below).
+       IINNSSIIDDEE__EEMMAACCSS
+              If  this  variable  appears  in  the  environment when the shell
+              starts, bbaasshh assumes that it is running inside  an  Emacs  shell
+              buffer  and  may disable line editing, depending on the value of
+              TTEERRMM.
+       LLAANNGG   Used to determine the  locale  category  for  any  category  not
+              specifically selected with a variable starting with LLCC__.
+       LLCC__AALLLL This  variable  overrides  the  value  of LLAANNGG and any other LLCC__
+              variable specifying a locale category.
+       LLCC__CCOOLLLLAATTEE
+              This variable determines the collation order used  when  sorting
+              the  results  of pathname expansion, and determines the behavior
+              of range expressions, equivalence  classes,  and  collating  se-
+              quences within pathname expansion and pattern matching.
+       LLCC__CCTTYYPPEE
+              This  variable  determines  the interpretation of characters and
+              the behavior of character classes within pathname expansion  and
+              pattern matching.
+       LLCC__MMEESSSSAAGGEESS
+              This  variable  determines  the locale used to translate double-
+              quoted strings preceded by a $$.
+       LLCC__NNUUMMEERRIICC
+              This variable determines the locale  category  used  for  number
+              formatting.
+       LLCC__TTIIMMEE
+              This  variable  determines the locale category used for data and
+              time formatting.
+       LLIINNEESS  Used by the sseelleecctt compound  command  to  determine  the  column
+              length  for  printing selection lists.  Automatically set if the
+              cchheecckkwwiinnssiizzee option is enabled or in an interactive  shell  upon
+              receipt of a SSIIGGWWIINNCCHH.
+       MMAAIILL   If  this  parameter  is  set to a file or directory name and the
+              MMAAIILLPPAATTHH variable is not set, bbaasshh informs the user of  the  ar-
+              rival of mail in the specified file or Maildir-format directory.
+       MMAAIILLCCHHEECCKK
+              Specifies  how often (in seconds) bbaasshh checks for mail.  The de-
+              fault is 60 seconds.  When it is time to  check  for  mail,  the
+              shell  does  so  before  displaying the primary prompt.  If this
+              variable is unset, or set to  a  value  that  is  not  a  number
+              greater than or equal to zero, the shell disables mail checking.
+       MMAAIILLPPAATTHH
+              A colon-separated list of filenames to be checked for mail.  The
+              message to be printed when mail arrives in a particular file may
+              be  specified by separating the filename from the message with a
+              `?'.  When used in the text of the message, $$__  expands  to  the
+              name of the current mailfile.  Example:
+              MMAAIILLPPAATTHH='/var/mail/bfox?"You  have  mail":~/shell-mail?"$_  has
+              mail!"'
+              BBaasshh can be configured to supply a default value for this  vari-
+              able  (there  is  no  value by default), but the location of the
+              user  mail  files  that  it  uses  is  system  dependent  (e.g.,
+              /var/mail/$$UUSSEERR).
+       OOPPTTEERRRR If set to the value 1, bbaasshh displays error messages generated by
+              the ggeettooppttss builtin command (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS  below).
+              OOPPTTEERRRR  is  initialized to 1 each time the shell is invoked or a
+              shell script is executed.
+       PPAATTHH   The search path for commands.  It is a colon-separated  list  of
+              directories  in  which the shell looks for commands (see CCOOMMMMAANNDD
+              EEXXEECCUUTTIIOONN below).  A zero-length (null) directory  name  in  the
+              value of PPAATTHH indicates the current directory.  A null directory
+              name may appear as two adjacent colons,  or  as  an  initial  or
+              trailing  colon.   The  default path is system-dependent, and is
+              set by the administrator who installs bbaasshh.  A common value is
+              ``/usr/local/bin:/usr/lo-
+              cal/sbin:/usr/bin:/usr/sbin:/bin:/sbin''.
+       PPOOSSIIXXLLYY__CCOORRRREECCTT
+              If this variable is in the environment  when  bbaasshh  starts,  the

+              the ----ppoossiixx invocation option had been supplied.  If it  is  set
+              while  the  shell is running, bbaasshh enables _p_o_s_i_x _m_o_d_e, as if the
+              command _s_e_t _-_o _p_o_s_i_x had been executed.  When the  shell  enters
+              _p_o_s_i_x _m_o_d_e, it sets this variable if it was not already set.
+       PPRROOMMPPTT__CCOOMMMMAANNDD
+              If  this variable is set, and is an array, the value of each set
+              element is executed as a command prior to issuing  each  primary
+              prompt.   If this is set but not an array variable, its value is
+              used as a command to execute instead.
+       PPRROOMMPPTT__DDIIRRTTRRIIMM
+              If set to a number greater than zero, the value is used  as  the
+              number of trailing directory components to retain when expanding
+              the \\ww and \\WW  prompt  string  escapes  (see  PPRROOMMPPTTIINNGG  below).
+              Characters removed are replaced with an ellipsis.
+       PPSS00    The  value  of  this parameter is expanded (see PPRROOMMPPTTIINNGG below)
+              and displayed by interactive shells after reading a command  and
+              before the command is executed.
+       PPSS11    The  value  of  this parameter is expanded (see PPRROOMMPPTTIINNGG below)
+              and used as the primary prompt string.   The  default  value  is
+              ``\\ss--\\vv\\$$ ''.
+       PPSS22    The  value of this parameter is expanded as with PPSS11 and used as
+              the secondary prompt string.  The default is ``>> ''.
+       PPSS33    The value of this parameter is used as the prompt for the sseelleecctt
+              command (see SSHHEELLLL GGRRAAMMMMAARR above).
+       PPSS44    The  value  of  this  parameter  is expanded as with PPSS11 and the
+              value is printed before each command bbaasshh displays during an ex-
+              ecution trace.  The first character of the expanded value of PPSS44
+              is replicated multiple times, as necessary, to indicate multiple
+              levels of indirection.  The default is ``++ ''.
+       SSHHEELLLL  This  variable expands to the full pathname to the shell.  If it
+              is not set when the shell starts, bbaasshh assigns to  it  the  full
+              pathname of the current user's login shell.
+       TTIIMMEEFFOORRMMAATT
+              The  value of this parameter is used as a format string specify-
+              ing how the timing information for pipelines prefixed  with  the
+              ttiimmee  reserved word should be displayed.  The %% character intro-
+              duces an escape sequence that is expanded to  a  time  value  or
+              other  information.  The escape sequences and their meanings are
+              as follows; the braces denote optional portions.
+              %%%%        A literal %%.
+              %%[[_p]][[ll]]RR  The elapsed time in seconds.
+              %%[[_p]][[ll]]UU  The number of CPU seconds spent in user mode.
+              %%[[_p]][[ll]]SS  The number of CPU seconds spent in system mode.
+              %%PP        The CPU percentage, computed as (%U + %S) / %R.
+
+              The optional _p is a digit specifying the _p_r_e_c_i_s_i_o_n,  the  number
+              of fractional digits after a decimal point.  A value of 0 causes
+              no decimal point or fraction to be output.  At most three places
+              after  the  decimal  point may be specified; values of _p greater
+              than 3 are changed to 3.  If _p is not specified, the value 3  is
+              used.
+
+              The  optional ll specifies a longer format, including minutes, of
+              the form _M_Mm_S_S._F_Fs.  The value of _p determines  whether  or  not
+              the fraction is included.
+
+              If  this  variable  is not set, bbaasshh acts as if it had the value
+              $$''\\nnrreeaall\\tt%%33llRR\\nnuusseerr\\tt%%33llUU\\nnssyyss\\tt%%33llSS''.  If the value  is  null,
+              no timing information is displayed.  A trailing newline is added
+              when the format string is displayed.
+       TTMMOOUUTT  If set to a value greater than zero, TTMMOOUUTT is treated as the de-
+              fault  timeout  for the rreeaadd builtin.  The sseelleecctt command termi-
+              nates if input does not arrive after TTMMOOUUTT seconds when input is
+              coming  from  a terminal.  In an interactive shell, the value is
+              interpreted as the number of seconds to wait for a line of input
+              after issuing the primary prompt.  BBaasshh terminates after waiting
+              for that number of seconds if a complete line of input does  not
+              arrive.
+       TTMMPPDDIIRR If  set, bbaasshh uses its value as the name of a directory in which
+              bbaasshh creates temporary files for the shell's use.
+       aauuttoo__rreessuummee
+              This variable controls how the shell interacts with the user and
+              job  control.   If this variable is set, single word simple com-
+              mands without redirections are treated as candidates for resump-
+              tion of an existing stopped job.  There is no ambiguity allowed;
+              if there is more than one job beginning with the  string  typed,
+              the  job  most  recently  accessed  is  selected.  The _n_a_m_e of a
+              stopped job, in this context, is the command line used to  start
+              it.   If  set to the value _e_x_a_c_t, the string supplied must match
+              the name of a stopped job exactly;  if  set  to  _s_u_b_s_t_r_i_n_g,  the
+              string  supplied  needs  to  match  a substring of the name of a
+              stopped job.  The _s_u_b_s_t_r_i_n_g value provides functionality  analo-
+              gous  to the %%??  job identifier (see JJOOBB CCOONNTTRROOLL below).  If set
+              to any other value, the supplied string must be a  prefix  of  a
+              stopped job's name; this provides functionality analogous to the
+              %%_s_t_r_i_n_g job identifier.
+       hhiissttcchhaarrss
+              The two or three characters which control history expansion  and
+              tokenization (see HHIISSTTOORRYY EEXXPPAANNSSIIOONN below).  The first character
+              is the _h_i_s_t_o_r_y _e_x_p_a_n_s_i_o_n character, the character which  signals
+              the  start  of  a  history  expansion, normally `!!'.  The second
+              character is the _q_u_i_c_k _s_u_b_s_t_i_t_u_t_i_o_n character, which is used  as
+              shorthand  for  re-running the previous command entered, substi-
+              tuting one string for another in the command.   The  default  is
+              `^^'.   The optional third character is the character which indi-
+              cates that the remainder of the line is a comment when found  as
+              the  first  character of a word, normally `##'.  The history com-
+              ment character causes history substitution to be skipped for the
+              remaining  words on the line.  It does not necessarily cause the
+              shell parser to treat the rest of the line as a comment.
+
+   AArrrraayyss
+       BBaasshh provides one-dimensional indexed and associative array  variables.
+       Any  variable may be used as an indexed array; the ddeeccllaarree builtin will
+       explicitly declare an array.  There is no maximum limit on the size  of
+       an  array, nor any requirement that members be indexed or assigned con-
+       tiguously.  Indexed arrays are  referenced  using  integers  (including
+       arithmetic expressions) and are zero-based; associative arrays are ref-
+       erenced using arbitrary strings.  Unless otherwise noted, indexed array
+       indices must be non-negative integers.
+
+       An  indexed  array is created automatically if any variable is assigned
+       to using the syntax _n_a_m_e[_s_u_b_s_c_r_i_p_t]=_v_a_l_u_e.  The _s_u_b_s_c_r_i_p_t is treated as
+       an arithmetic expression that must evaluate to a number.  To explicitly
+       declare an indexed array, use ddeeccllaarree --aa _n_a_m_e (see SSHHEELLLL  BBUUIILLTTIINN  CCOOMM--
+       MMAANNDDSS  below).   ddeeccllaarree  --aa _n_a_m_e[[_s_u_b_s_c_r_i_p_t]] is also accepted; the _s_u_b_-
+       _s_c_r_i_p_t is ignored.
+
+       Associative arrays are created using ddeeccllaarree --AA _n_a_m_e.
+
+       Attributes may be specified for an array variable using the ddeeccllaarree and
+       rreeaaddoonnllyy builtins.  Each attribute applies to all members of an array.
+
+       Arrays   are  assigned  to  using  compound  assignments  of  the  form
+       _n_a_m_e=((value_1 ... value_n)), where each _v_a_l_u_e may be  of  the  form  [_s_u_b_-
+       _s_c_r_i_p_t]=_s_t_r_i_n_g.   Indexed array assignments do not require anything but
+       _s_t_r_i_n_g.  Each _v_a_l_u_e in the list is expanded using all the shell  expan-
+       sions  described  below under EEXXPPAANNSSIIOONN.  When assigning to indexed ar-
+       rays, if the optional brackets and subscript are supplied,  that  index
+       is assigned to; otherwise the index of the element assigned is the last
+       index assigned to by the statement plus one.  Indexing starts at zero.
+
+       When assigning to an associative array, the words in a compound assign-
+       ment  may  be  either assignment statements, for which the subscript is
+       required, or a list of words that is interpreted as a sequence  of  al-
+       ternating  keys and values: _n_a_m_e=(( _k_e_y_1 _v_a_l_u_e_1 _k_e_y_2 _v_a_l_u_e_2 ...)).  These
+       are treated identically to  _n_a_m_e=((  [_k_e_y_1]=_v_a_l_u_e_1  [_k_e_y_2]=_v_a_l_u_e_2  ...)).
+       The  first  word in the list determines how the remaining words are in-
+       terpreted; all assignments in a list must be of the  same  type.   When
+       using  key/value  pairs,  the keys may not be missing or empty; a final
+       missing value is treated like the empty string.
+
+       This syntax is also accepted by the ddeeccllaarree builtin.  Individual  array
+       elements  may be assigned to using the _n_a_m_e[_s_u_b_s_c_r_i_p_t]=_v_a_l_u_e syntax in-
+       troduced above.  When assigning to an indexed array, if  _n_a_m_e  is  sub-
+       scripted  by  a negative number, that number is interpreted as relative
+       to one greater than the maximum index  of  _n_a_m_e,  so  negative  indices
+       count back from the end of the array, and an index of -1 references the
+       last element.
+
+       The += operator will append to an array variable when  assigning  using
+       the compound assignment syntax; see PPAARRAAMMEETTEERRSS above.
+
+       Any  element  of  an  array may be referenced using ${_n_a_m_e[_s_u_b_s_c_r_i_p_t]}.
+       The braces are required to avoid conflicts with pathname expansion.  If
+       _s_u_b_s_c_r_i_p_t  is  @@  or **, the word expands to all members of _n_a_m_e.  These
+       subscripts differ only when the word appears within double quotes.   If
+       the word is double-quoted, ${_n_a_m_e[*]} expands to a single word with the
+       value of each array member separated by the first character of the  IIFFSS
+       special variable, and ${_n_a_m_e[@]} expands each element of _n_a_m_e to a sep-
+       arate word.  When there are no array  members,  ${_n_a_m_e[@]}  expands  to
+       nothing.   If the double-quoted expansion occurs within a word, the ex-
+       pansion of the first parameter is joined with the beginning part of the
+       original  word,  and the expansion of the last parameter is joined with
+       the last part of the original word.  This is analogous to the expansion
+       of  the  special  parameters  **  and  @@ (see SSppeecciiaall PPaarraammeetteerrss above).
+       ${#_n_a_m_e[_s_u_b_s_c_r_i_p_t]} expands to the length  of  ${_n_a_m_e[_s_u_b_s_c_r_i_p_t]}.   If
+       _s_u_b_s_c_r_i_p_t is ** or @@, the expansion is the number of elements in the ar-
+       ray.  If the _s_u_b_s_c_r_i_p_t used to reference an element of an indexed array
+       evaluates  to a number less than zero, it is interpreted as relative to
+       one greater than the maximum index of the array,  so  negative  indices
+       count back from the end of the array, and an index of -1 references the
+       last element.
+
+       Referencing an array variable without a subscript is equivalent to ref-
+       erencing  the array with a subscript of 0.  Any reference to a variable
+       using a valid subscript is legal, and bbaasshh will create an array if nec-
+       essary.
+
+       An  array variable is considered set if a subscript has been assigned a
+       value.  The null string is a valid value.
+
+       It is possible to obtain the keys (indices) of an array as well as  the
+       values.   ${!!_n_a_m_e[_@]} and ${!!_n_a_m_e[_*]} expand to the indices assigned in
+       array variable _n_a_m_e.  The treatment when in double quotes is similar to
+       the expansion of the special parameters _@ and _* within double quotes.
+
+       The uunnsseett builtin is used to destroy arrays.  uunnsseett _n_a_m_e[_s_u_b_s_c_r_i_p_t] de-
+       stroys the array element at index _s_u_b_s_c_r_i_p_t, for both indexed and asso-
+       ciative  arrays.  Negative subscripts to indexed arrays are interpreted
+       as described above.  Unsetting the last element of  an  array  variable
+       does  not  unset the variable.  uunnsseett _n_a_m_e, where _n_a_m_e is an array, re-
+       moves the entire array.  uunnsseett _n_a_m_e[_s_u_b_s_c_r_i_p_t], where _s_u_b_s_c_r_i_p_t is ** or
+       @@, behaves differently depending on whether _n_a_m_e is an indexed or asso-
+       ciative array.  If _n_a_m_e is an associative array, this unsets  the  ele-
+       ment with subscript ** or @@.  If _n_a_m_e is an indexed array, unset removes
+       all of the elements but does not remove the array itself.
+
+       When using a variable name with a subscript as an argument  to  a  com-
+       mand,  such  as with uunnsseett, without using the word expansion syntax de-
+       scribed above, the argument is subject to pathname expansion.  If path-
+       name expansion is not desired, the argument should be quoted.
+
+       The  ddeeccllaarree,  llooccaall,  and rreeaaddoonnllyy builtins each accept a --aa option to
+       specify an indexed array and a --AA option to specify an associative  ar-
+       ray.   If  both  options  are  supplied, --AA takes precedence.  The rreeaadd
+       builtin accepts a --aa option to assign a list of  words  read  from  the
+       standard input to an array.  The sseett and ddeeccllaarree builtins display array
+       values in a way that allows them to be reused as assignments.
+
+EEXXPPAANNSSIIOONN
+       Expansion is performed on the command line after it has been split into
+       words.   There are seven kinds of expansion performed: _b_r_a_c_e _e_x_p_a_n_s_i_o_n,
+       _t_i_l_d_e _e_x_p_a_n_s_i_o_n, _p_a_r_a_m_e_t_e_r _a_n_d _v_a_r_i_a_b_l_e  _e_x_p_a_n_s_i_o_n,  _c_o_m_m_a_n_d  _s_u_b_s_t_i_t_u_-
+       _t_i_o_n, _a_r_i_t_h_m_e_t_i_c _e_x_p_a_n_s_i_o_n, _w_o_r_d _s_p_l_i_t_t_i_n_g, and _p_a_t_h_n_a_m_e _e_x_p_a_n_s_i_o_n.
+
+       The order of expansions is: brace expansion; tilde expansion, parameter
+       and variable expansion, arithmetic expansion, and command  substitution
+       (done  in a left-to-right fashion); word splitting; and pathname expan-
+       sion.
+
+       On systems that can support it, there is an additional expansion avail-
+       able:  _p_r_o_c_e_s_s  _s_u_b_s_t_i_t_u_t_i_o_n.   This  is  performed at the same time as
+       tilde, parameter, variable, and arithmetic expansion and  command  sub-
+       stitution.
+
+       After  these  expansions are performed, quote characters present in the
+       original word are removed  unless  they  have  been  quoted  themselves
+       (_q_u_o_t_e _r_e_m_o_v_a_l).
+
+       Only  brace  expansion,  word splitting, and pathname expansion can in-
+       crease the number of words of the expansion; other expansions expand  a
+       single  word to a single word.  The only exceptions to this are the ex-
+       pansions  of  "$$@@"  and  "$${{_n_a_m_e[[@@]]}}",  and,  in  most  cases,  $$**  and
+       $${{_n_a_m_e[[**]]}} as explained above (see PPAARRAAMMEETTEERRSS).
+
+   BBrraaccee EExxppaannssiioonn
+       _B_r_a_c_e _e_x_p_a_n_s_i_o_n is a mechanism by which arbitrary strings may be gener-
+       ated.  This mechanism is similar to _p_a_t_h_n_a_m_e _e_x_p_a_n_s_i_o_n, but  the  file-
+       names generated need not exist.  Patterns to be brace expanded take the
+       form of an optional _p_r_e_a_m_b_l_e, followed by either a series of comma-sep-
+       arated  strings or a sequence expression between a pair of braces, fol-
+       lowed by an optional _p_o_s_t_s_c_r_i_p_t.  The  preamble  is  prefixed  to  each
+       string contained within the braces, and the postscript is then appended
+       to each resulting string, expanding left to right.
+
+       Brace expansions may be nested.  The results of  each  expanded  string
+       are  not  sorted;  left  to  right  order  is  preserved.  For example,
+       a{{d,c,b}}e expands into `ade ace abe'.
+
+       A sequence expression takes the form {{_x...._y[[...._i_n_c_r]]}}, where _x and _y  are
+       either  integers or single letters, and _i_n_c_r, an optional increment, is
+       an integer.  When integers are supplied, the expression expands to each
+       number  between  _x and _y, inclusive.  Supplied integers may be prefixed
+       with _0 to force each term to have the same width.  When either _x  or  _y
+       begins  with a zero, the shell attempts to force all generated terms to
+       contain the same number of digits, zero-padding where necessary.   When
+       letters  are supplied, the expression expands to each character lexico-
+       graphically between _x and _y, inclusive, using  the  default  C  locale.
+       Note  that  both  _x and _y must be of the same type (integer or letter).
+       When the increment is supplied, it is used as  the  difference  between
+       each term.  The default increment is 1 or -1 as appropriate.
+
+       Brace expansion is performed before any other expansions, and any char-
+       acters special to other expansions are preserved in the result.  It  is
+       strictly  textual.  BBaasshh does not apply any syntactic interpretation to
+       the context of the expansion or the text between the braces.
+
+       A correctly-formed brace expansion must contain  unquoted  opening  and
+       closing braces, and at least one unquoted comma or a valid sequence ex-
+       pression.  Any incorrectly formed brace expansion is left unchanged.  A
+       {{  or  ,, may be quoted with a backslash to prevent its being considered
+       part of a brace expression.  To avoid conflicts with  parameter  expan-
+       sion, the string $${{ is not considered eligible for brace expansion, and
+       inhibits brace expansion until the closing }}.
+
+       This construct is typically used as shorthand when the common prefix of
+       the strings to be generated is longer than in the above example:
+
+              mkdir /usr/local/src/bash/{old,new,dist,bugs}
+       or
+              chown root /usr/{ucb/{ex,edit},lib/{ex?.?*,how_ex}}
+
+       Brace  expansion  introduces  a  slight incompatibility with historical
+       versions of sshh.  sshh does not treat opening or closing braces  specially
+       when  they  appear as part of a word, and preserves them in the output.
+       BBaasshh removes braces from words as a  consequence  of  brace  expansion.
+       For  example,  a word entered to sshh as _f_i_l_e_{_1_,_2_} appears identically in
+       the output.  The same word is output as _f_i_l_e_1 _f_i_l_e_2 after expansion  by
+       bbaasshh.   If strict compatibility with sshh is desired, start bbaasshh with the
+       ++BB option or disable brace expansion with the ++BB option to the sseett com-
+       mand (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below).

+       If  a  word  begins  with an unquoted tilde character (`~~'), all of the
+       characters preceding the first unquoted slash (or  all  characters,  if
+       there  is no unquoted slash) are considered a _t_i_l_d_e_-_p_r_e_f_i_x.  If none of
+       the characters in the tilde-prefix are quoted, the  characters  in  the
+       tilde-prefix  following the tilde are treated as a possible _l_o_g_i_n _n_a_m_e.
+       If this login name is the null string, the tilde is replaced  with  the
+       value  of  the shell parameter HHOOMMEE.  If HHOOMMEE is unset, the home direc-
+       tory of the user executing the shell is  substituted  instead.   Other-
+       wise,  the  tilde-prefix is replaced with the home directory associated
+       with the specified login name.
+
+       If the tilde-prefix is a `~+', the value of the shell variable PPWWDD  re-
+       places  the  tilde-prefix.  If the tilde-prefix is a `~-', the value of
+       the shell variable OOLLDDPPWWDD, if it is set, is substituted.  If the  char-
+       acters  following  the tilde in the tilde-prefix consist of a number _N,
+       optionally prefixed by a `+' or a `-',  the  tilde-prefix  is  replaced
+       with the corresponding element from the directory stack, as it would be
+       displayed by the ddiirrss builtin invoked with the tilde-prefix as an argu-
+       ment.   If  the characters following the tilde in the tilde-prefix con-
+       sist of a number without a leading `+' or `-', `+' is assumed.
+
+       If the login name is invalid, or the tilde expansion fails, the word is
+       unchanged.
+
+       Each variable assignment is checked for unquoted tilde-prefixes immedi-
+       ately following a :: or the first ==.  In these cases, tilde expansion is
+       also performed.  Consequently, one may use filenames with tildes in as-
+       signments to PPAATTHH, MMAAIILLPPAATTHH, and CCDDPPAATTHH, and the shell assigns the  ex-
+       panded value.
+
+       Bash  also  performs tilde expansion on words satisfying the conditions
+       of variable assignments (as described above under PPAARRAAMMEETTEERRSS) when they
+       appear  as arguments to simple commands.  Bash does not do this, except
+       for the _d_e_c_l_a_r_a_t_i_o_n commands listed above, when in _p_o_s_i_x _m_o_d_e.

+       The `$$' character introduces parameter expansion, command substitution,
+       or  arithmetic  expansion.  The parameter name or symbol to be expanded
+       may be enclosed in braces, which are optional but serve to protect  the
+       variable  to be expanded from characters immediately following it which
+       could be interpreted as part of the name.
+
+       When braces are used, the matching ending brace is the  first  `}}'  not
+       escaped by a backslash or within a quoted string, and not within an em-
+       bedded arithmetic expansion, command substitution, or parameter  expan-
+       sion.

+              digit, or when _p_a_r_a_m_e_t_e_r is followed by a character which is not
+              to be interpreted as part of its name.  The _p_a_r_a_m_e_t_e_r is a shell
+              parameter  as  described above PPAARRAAMMEETTEERRSS) or an array reference
+              (AArrrraayyss).
+
+       If the first character of _p_a_r_a_m_e_t_e_r is an exclamation  point  (!!),  and
+       _p_a_r_a_m_e_t_e_r is not a _n_a_m_e_r_e_f, it introduces a level of indirection.  BBaasshh
+       uses the value formed by expanding the rest of _p_a_r_a_m_e_t_e_r as the new _p_a_-
+       _r_a_m_e_t_e_r;  this  is  then expanded and that value is used in the rest of
+       the expansion, rather than the expansion  of  the  original  _p_a_r_a_m_e_t_e_r.
+       This is known as _i_n_d_i_r_e_c_t _e_x_p_a_n_s_i_o_n.  The value is subject to tilde ex-
+       pansion, parameter expansion, command substitution, and arithmetic  ex-
+       pansion.   If  _p_a_r_a_m_e_t_e_r  is a nameref, this expands to the name of the
+       parameter referenced by _p_a_r_a_m_e_t_e_r instead of  performing  the  complete
+       indirect  expansion.   The  exceptions  to  this  are the expansions of
+       ${!!_p_r_e_f_i_x**} and ${!!_n_a_m_e[_@]} described  below.   The  exclamation  point
+       must  immediately  follow the left brace in order to introduce indirec-

+
+       When not performing substring expansion, using the forms documented be-

+              end of the expanded value of _p_a_r_a_m_e_t_e_r.   If  the  expansion  of
+              _s_t_r_i_n_g  is  null,  matches of _p_a_t_t_e_r_n are deleted.  If _s_t_r_i_n_g is

+              Quoting any part of _s_t_r_i_n_g inhibits replacement in the expansion
+              of the quoted portion, including replacement strings  stored  in
+              shell  variables.   Backslash will escape && in _s_t_r_i_n_g; the back-
+              slash is removed in order to permit a literal && in the  replace-
+              ment  string.  Backslash can also be used to escape a backslash;
+              \\\\ results in a literal backslash  in  the  replacement.   Users
+              should  take  care  if _s_t_r_i_n_g is double-quoted to avoid unwanted
+              interactions between the  backslash  and  double-quoting,  since
+              backslash  has  special  meaning  within double quotes.  Pattern
+              substitution performs the check for unquoted &&  after  expanding
+              _s_t_r_i_n_g; shell programmers should quote any occurrences of && they
+              want to be taken literally in the replacement and ensure any in-
+              stances of && they want to be replaced are unquoted.

+       _C_o_m_m_a_n_d _s_u_b_s_t_i_t_u_t_i_o_n allows the output of a command to replace the com-
+       mand name.  There are two forms:
+
+              $$((_c_o_m_m_a_n_d))
+       or
+              ``_c_o_m_m_a_n_d``
+
+       BBaasshh performs the expansion by executing _c_o_m_m_a_n_d in a subshell environ-
+       ment and replacing the command substitution with the standard output of
+       the command, with any trailing newlines deleted.  Embedded newlines are
+       not deleted, but they may be removed during word splitting.   The  com-
+       mand  substitution  $$((ccaatt  _f_i_l_e))  can be replaced by the equivalent but
+       faster $$((<< _f_i_l_e)).
+
+       When the old-style backquote form of substitution  is  used,  backslash
+       retains  its  literal  meaning except when followed by $$, ``, or \\.  The
+       first backquote not preceded by a backslash terminates the command sub-
+       stitution.   When using the $(_c_o_m_m_a_n_d) form, all characters between the
+       parentheses make up the command; none are treated specially.
+
+       Command substitutions may be nested.  To nest when using the backquoted
+       form, escape the inner backquotes with backslashes.
+
+       If  the  substitution  appears within double quotes, word splitting and

+
+       The _e_x_p_r_e_s_s_i_o_n undergoes the same expansions as if it were within  dou-
+       ble  quotes,  but double quote characters in _e_x_p_r_e_s_s_i_o_n are not treated
+       specially and are removed.  All tokens in the expression undergo param-
+       eter  and  variable expansion, command substitution, and quote removal.
+       The result is treated as the arithmetic  expression  to  be  evaluated.
+       Arithmetic expansions may be nested.

+       to using a filename.  It takes the form of  <<((_l_i_s_t))  or  >>((_l_i_s_t)).   The
+       process  _l_i_s_t is run asynchronously, and its input or output appears as
+       a filename.  This filename is passed as an argument to the current com-
+       mand  as  the  result  of  the expansion.  If the >>((_l_i_s_t)) form is used,
+       writing to the file will provide input for _l_i_s_t.  If the  <<((_l_i_s_t))  form
+       is  used,  the  file passed as an argument should be read to obtain the
+       output of _l_i_s_t.  Process substitution is supported on systems that sup-
+       port named pipes (_F_I_F_O_s) or the //ddeevv//ffdd method of naming open files.
+
+       When  available,  process substitution is performed simultaneously with

+       The  shell  treats each character of IIFFSS as a delimiter, and splits the

+       field   terminators.   If  IIFFSS  is  unset,  or  its  value  is  exactly
+       <<ssppaaccee>><<ttaabb>><<nneewwlliinnee>>, the default, then sequences of  <<ssppaaccee>>,  <<ttaabb>>,
+       and  <<nneewwlliinnee>>  at the beginning and end of the results of the previous
+       expansions are ignored, and any sequence of IIFFSS characters not  at  the
+       beginning  or  end  serves  to delimit words.  If IIFFSS has a value other
+       than the default, then sequences of the  whitespace  characters  ssppaaccee,
+       ttaabb,  and  nneewwlliinnee are ignored at the beginning and end of the word, as
+       long as the whitespace character is in the value of IIFFSS (an IIFFSS  white-
+       space  character).   Any  character  in IIFFSS that is not IIFFSS whitespace,
+       along with any adjacent IIFFSS whitespace characters, delimits a field.  A
+       sequence  of  IIFFSS whitespace characters is also treated as a delimiter.
+       If the value of IIFFSS is null, no word splitting occurs.
+
+       Explicit null arguments ("""" or '''') are retained and passed to  commands
+       as empty strings.  Unquoted implicit null arguments, resulting from the
+       expansion of parameters that have no values, are removed.  If a parame-
+       ter with no value is expanded within double quotes, a null argument re-
+       sults and is retained and passed to a command as an empty string.  When
+       a  quoted  null  argument  appears as part of a word whose expansion is
+       non-null, the null argument is removed.  That is, the word -d'' becomes
+       -d after word splitting and null argument removal.
+
+       Note that if no expansion occurs, no splitting is performed.

+       After  word  splitting,  unless  the --ff option has been set, bbaasshh scans
+       each word for the characters **, ??, and [[.  If one of  these  characters
+       appears, and is not quoted, then the word is regarded as a _p_a_t_t_e_r_n, and
+       replaced with an alphabetically sorted list of filenames  matching  the
+       pattern  (see  PPaatttteerrnn  MMaattcchhiinngg  below).  If no matching filenames are
+       found, and the shell option nnuullllgglloobb is not enabled, the word  is  left
+       unchanged.   If  the  nnuullllgglloobb option is set, and no matches are found,
+       the word is removed.  If the ffaaiillgglloobb  shell  option  is  set,  and  no
+       matches  are  found, an error message is printed and the command is not
+       executed.  If the shell option nnooccaasseegglloobb is enabled, the match is per-

+       pattern is used for pathname expansion, the  character  ````..''''   at  the
+       start  of  a  name or immediately following a slash must be matched ex-
+       plicitly, unless the shell option ddoottgglloobb is set.  In  order  to  match
+       the filenames ````..''''  and ````....'''', the pattern must begin with ``.'' (for
+       example, ``.?''), even if ddoottgglloobb is set.  If  the  gglloobbsskkiippddoottss  shell
+       option  is enabled, the filenames ````..''''  and ````....''''  are never matched,
+       even if the pattern begins with a ````..''''.  When not matching  pathnames,
+       the  ````..''''   character is not treated specially.  When matching a path-
+       name, the slash character must always be matched explicitly by a  slash
+       in  the  pattern, but in other matching contexts it can be matched by a
+       special pattern character as described below  under  PPaatttteerrnn  MMaattcchhiinngg.

+       name  that  also  matches  one of the patterns in GGLLOOBBIIGGNNOORREE is removed

+       ing  against  the patterns in GGLLOOBBIIGGNNOORREE is performed without regard to
+       case.  The filenames ````..''''  and ````....''''  are always ignored when GGLLOOBBIIGG--
+       NNOORREE  is  set  and not null.  However, setting GGLLOOBBIIGGNNOORREE to a non-null
+       value has the effect of enabling the ddoottgglloobb shell option, so all other
+       filenames  beginning with a ````..''''  will match.  To get the old behavior
+       of ignoring filenames beginning with a ````..'''', make ````..**''''  one  of  the
+       patterns in GGLLOOBBIIGGNNOORREE.  The ddoottgglloobb option is disabled when GGLLOOBBIIGGNNOORREE

+       Any character that appears in a pattern, other than the special pattern

+
+       If the eexxttgglloobb shell option is enabled using  the  sshhoopptt  builtin,  the
+       shell  recognizes  several extended pattern matching operators.  In the
+       following description, a _p_a_t_t_e_r_n_-_l_i_s_t is a list of one or more patterns
+       separated  by  a ||.  Composite patterns may be formed using one or more
+       of the following sub-patterns:
+
+              ??((_p_a_t_t_e_r_n_-_l_i_s_t))
+                     Matches zero or one occurrence of the given patterns
+              **((_p_a_t_t_e_r_n_-_l_i_s_t))
+                     Matches zero or more occurrences of the given patterns
+              ++((_p_a_t_t_e_r_n_-_l_i_s_t))
+                     Matches one or more occurrences of the given patterns
+              @@((_p_a_t_t_e_r_n_-_l_i_s_t))
+                     Matches one of the given patterns
+              !!((_p_a_t_t_e_r_n_-_l_i_s_t))
+                     Matches anything except one of the given patterns
+
+       Theeexxttgglloobb option changes the behavior of the parser, since the  paren-
+       theses  are  normally  treated as operators with syntactic meaning.  To
+       ensure that extended matching patterns are parsed correctly, make  sure
+       that  eexxttgglloobb  is enabled before parsing constructs containing the pat-
+       terns, including shell functions and command substitutions.
+
+       When matching filenames, the ddoottgglloobb shell option determines the set of
+       filenames  that  are  tested: when ddoottgglloobb is enabled, the set of file-
+       names includes all files beginning with ``.'',  but  ``.''  and  ``..''
+       must  be  matched  by  a pattern or sub-pattern that begins with a dot;
+       when it is disabled, the set does not include any  filenames  beginning
+       with  ``.''  unless the pattern or sub-pattern begins with a ``.''.  As
+       above, ``.'' only has a special meaning when matching filenames.
+
+       Complicated extended pattern matching against long strings is slow, es-
+       pecially when the patterns contain alternations and the strings contain
+       multiple matches.  Using separate matches against shorter  strings,  or
+       using arrays of strings instead of a single long string, may be faster.
+
+   QQuuoottee RReemmoovvaall
+       After the preceding expansions, all unquoted occurrences of the charac-

+       are removed.

+RREEDDIIRREECCTTIIOONN
+       Before  a  command  is executed, its input and output may be _r_e_d_i_r_e_c_t_e_d
+       using a special notation interpreted by the shell.  _R_e_d_i_r_e_c_t_i_o_n  allows
+       commands'  file handles to be duplicated, opened, closed, made to refer
+       to different files, and can change the files the command reads from and
+       writes  to.  Redirection may also be used to modify file handles in the
+       current shell execution environment.  The following redirection  opera-
+       tors may precede or appear anywhere within a _s_i_m_p_l_e _c_o_m_m_a_n_d or may fol-
+       low a _c_o_m_m_a_n_d.  Redirections are processed in the  order  they  appear,
+       from left to right.
+
+       Each  redirection  that may be preceded by a file descriptor number may
+       instead be preceded by a word of the form {_v_a_r_n_a_m_e}.  In this case, for
+       each redirection operator except >&- and <&-, the shell will allocate a
+       file descriptor greater than or equal to 10 and assign it  to  _v_a_r_n_a_m_e.
+       If  >&-  or  <&- is preceded by {_v_a_r_n_a_m_e}, the value of _v_a_r_n_a_m_e defines
+       the file descriptor to close.  If {_v_a_r_n_a_m_e} is supplied, the  redirect-
+       ion  persists  beyond the scope of the command, allowing the shell pro-
+       grammer  to  manage  the  file  descriptor's  lifetime  manually.   The
+       vvaarrrreeddiirr__cclloossee shell option manages this behavior.
+
+       In  the  following descriptions, if the file descriptor number is omit-
+       ted, and the first character of the redirection operator is <<, the  re-
+       direction  refers  to  the  standard input (file descriptor 0).  If the
+       first character of the  redirection  operator  is  >>,  the  redirection
+       refers to the standard output (file descriptor 1).
+
+       The  word  following the redirection operator in the following descrip-
+       tions, unless otherwise noted, is subjected to brace  expansion,  tilde
+       expansion,  parameter  and  variable  expansion,  command substitution,
+       arithmetic expansion,  quote  removal,  pathname  expansion,  and  word
+       splitting.  If it expands to more than one word, bbaasshh reports an error.
+
+       Note  that  the order of redirections is significant.  For example, the
+       command
+
+              ls >> dirlist 2>>&&1
+
+       directs both standard output and standard error to  the  file  _d_i_r_l_i_s_t,
+       while the command
+
+              ls 2>>&&1 >> dirlist
+
+       directs  only the standard output to file _d_i_r_l_i_s_t, because the standard
+       error was duplicated from the standard output before the standard  out-
+       put was redirected to _d_i_r_l_i_s_t.
+
+       BBaasshh handles several filenames specially when they are used in redirec-
+       tions, as described in the following table.  If the operating system on
+       which bbaasshh is running provides these special files, bash will use them;
+       otherwise it will emulate them internally with the  behavior  described
+       below.
+
+              //ddeevv//ffdd//_f_d
+                     If  _f_d  is  a valid integer, file descriptor _f_d is dupli-
+                     cated.
+              //ddeevv//ssttddiinn
+                     File descriptor 0 is duplicated.
+              //ddeevv//ssttddoouutt
+                     File descriptor 1 is duplicated.
+              //ddeevv//ssttddeerrrr
+                     File descriptor 2 is duplicated.
+              //ddeevv//ttccpp//_h_o_s_t//_p_o_r_t
+                     If _h_o_s_t is a valid hostname or Internet address, and _p_o_r_t
+                     is  an integer port number or service name, bbaasshh attempts
+                     to open the corresponding TCP socket.
+              //ddeevv//uuddpp//_h_o_s_t//_p_o_r_t
+                     If _h_o_s_t is a valid hostname or Internet address, and _p_o_r_t
+                     is  an integer port number or service name, bbaasshh attempts
+                     to open the corresponding UDP socket.
+
+       A failure to open or create a file causes the redirection to fail.
+
+       Redirections using file descriptors greater than 9 should be used  with
+       care,  as they may conflict with file descriptors the shell uses inter-
+       nally.

+       current source until a line containing only _d_e_l_i_m_i_t_e_r (with no trailing
+       blanks) is seen.  All of the lines read up to that point are then  used

+
+       No parameter and variable expansion, command  substitution,  arithmetic
+       expansion,  or pathname expansion is performed on _w_o_r_d.  If any part of
+       _w_o_r_d is quoted, the _d_e_l_i_m_i_t_e_r is the result of quote removal  on  _w_o_r_d,
+       and  the  lines  in the here-document are not expanded.  If _w_o_r_d is un-

+
+       If the redirection operator is <<<<--, then all leading tab characters are

+       The redirection operator
+
+              [_n]<<&&_w_o_r_d
+
+       is used to duplicate input file descriptors.  If _w_o_r_d expands to one or
+       more  digits,  the file descriptor denoted by _n is made to be a copy of
+       that file descriptor.  If the digits in _w_o_r_d do not specify a file  de-

+AALLIIAASSEESS
+       _A_l_i_a_s_e_s allow a string to be substituted for a word when it is used  as
+       the  first  word  of  a  simple command.  The shell maintains a list of
+       aliases that may be set and unset with the aalliiaass  and  uunnaalliiaass  builtin
+       commands  (see  SSHHEELLLL  BBUUIILLTTIINN CCOOMMMMAANNDDSS below).  The first word of each
+       simple command, if unquoted, is checked to see if it has an alias.   If
+       so,  that word is replaced by the text of the alias.  The characters //,
+       $$, ``, and == and any of the shell _m_e_t_a_c_h_a_r_a_c_t_e_r_s or  quoting  characters
+       listed above may not appear in an alias name.  The replacement text may
+       contain any valid shell input,  including  shell  metacharacters.   The
+       first  word  of  the replacement text is tested for aliases, but a word
+       that is identical to an alias being expanded is not expanded  a  second
+       time.   This  means  that  one may alias llss to llss --FF, for instance, and
+       bbaasshh does not try to recursively expand the replacement text.   If  the
+       last  character  of  the  alias value is a _b_l_a_n_k, then the next command
+       word following the alias is also checked for alias expansion.
+
+       Aliases are created and listed with the aalliiaass command, and removed with
+       the uunnaalliiaass command.
+
+       There  is no mechanism for using arguments in the replacement text.  If
+       arguments are needed, use a shell function (see FFUUNNCCTTIIOONNSS below).
+
+       Aliases are not expanded when the shell is not interactive, unless  the
+       eexxppaanndd__aalliiaasseess  shell option is set using sshhoopptt (see the description of
+       sshhoopptt under SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below).
+
+       The rules concerning the definition and use  of  aliases  are  somewhat
+       confusing.   BBaasshh always reads at least one complete line of input, and
+       all lines that make up a compound command, before executing any of  the
+       commands  on  that  line or the compound command.  Aliases are expanded
+       when a command is read, not when it is executed.  Therefore,  an  alias
+       definition  appearing on the same line as another command does not take
+       effect until the next line of input is read.   The  commands  following
+       the  alias  definition  on that line are not affected by the new alias.
+       This behavior is also an issue when functions  are  executed.   Aliases
+       are  expanded when a function definition is read, not when the function
+       is executed, because a function definition is itself a command.   As  a
+       consequence,  aliases defined in a function are not available until af-
+       ter that function is executed.  To be safe, always  put  alias  defini-
+       tions on a separate line, and do not use aalliiaass in compound commands.
+
+       For almost every purpose, aliases are superseded by shell functions.
+
+FFUUNNCCTTIIOONNSS
+       A  shell  function,  defined  as  described  above under SSHHEELLLL GGRRAAMMMMAARR,
+       stores a series of commands for later execution.  When the  name  of  a
+       shell  function  is used as a simple command name, the list of commands
+       associated with that function name is executed.  Functions are executed
+       in  the  context of the current shell; no new process is created to in-
+       terpret them (contrast this with the  execution  of  a  shell  script).
+       When  a  function is executed, the arguments to the function become the

+       BBUUIILLTTIINN CCOOMMMMAANNDDSS below) are not inherited unless the function has  been
+       given  the  ttrraaccee attribute (see the description of the ddeeccllaarree builtin
+       below) or the --oo ffuunnccttrraaccee shell option has been enabled with  the  sseett
+       builtin  (in  which  case  all  functions  inherit the DDEEBBUUGG and RREETTUURRNN
+       traps), and the EERRRR trap is not inherited unless the --oo eerrrrttrraaccee  shell
+       option has been enabled.
+
+       Variables  local to the function may be declared with the llooccaall builtin
+       command (_l_o_c_a_l _v_a_r_i_a_b_l_e_s).  Ordinarily, variables and their values  are
+       shared  between the function and its caller.  If a variable is declared
+       llooccaall, the variable's visible scope is restricted to that function  and
+       its children (including the functions it calls).
+
+       In the following description, the _c_u_r_r_e_n_t _s_c_o_p_e is a currently- execut-
+       ing function.  Previous scopes consist of that function's caller and so
+       on,  back  to  the "global" scope, where the shell is not executing any
+       shell function.  Consequently, a local variable at the current scope is
+       a variable declared using the llooccaall or ddeeccllaarree builtins in the function
+       that is currently executing.
+
+       Local variables "shadow" variables with the same name declared at  pre-
+       vious  scopes.   For  instance, a local variable declared in a function
+       hides a global variable of the same name:  references  and  assignments
+       refer  to  the  local variable, leaving the global variable unmodified.
+       When the function returns, the global variable is once again visible.
+
+       The shell uses _d_y_n_a_m_i_c  _s_c_o_p_i_n_g  to  control  a  variable's  visibility
+       within  functions.   With  dynamic scoping, visible variables and their
+       values are a result of the sequence of function calls that caused  exe-
+       cution  to  reach the current function.  The value of a variable that a
+       function sees depends on its value within its caller, if  any,  whether
+       that  caller  is the "global" scope or another shell function.  This is
+       also the value that a local variable  declaration  "shadows",  and  the
+       value that is restored when the function returns.
+
+       For  example, if a variable _v_a_r is declared as local in function _f_u_n_c_1,
+       and _f_u_n_c_1 calls another function _f_u_n_c_2, references  to  _v_a_r  made  from
+       within _f_u_n_c_2 will resolve to the local variable _v_a_r from _f_u_n_c_1, shadow-
+       ing any global variable named _v_a_r.
+
+       The uunnsseett builtin also acts using the same dynamic scope: if a variable
+       is local to the current scope, uunnsseett will unset it; otherwise the unset
+       will refer to the variable found in  any  calling  scope  as  described
+       above.   If a variable at the current local scope is unset, it will re-
+       main so (appearing as unset) until it is reset in that scope  or  until
+       the  function  returns.  Once the function returns, any instance of the
+       variable at a previous scope will become visible.  If the unset acts on
+       a  variable  at  a previous scope, any instance of a variable with that
+       name that had been shadowed will become visible (see below how the  lloo--
+       ccaallvvaarr__uunnsseett shell option changes this behavior).
+
+       The  FFUUNNCCNNEESSTT  variable,  if set to a numeric value greater than 0, de-
+       fines a maximum function nesting level.  Function invocations that  ex-
+       ceed the limit cause the entire command to abort.
+
+       If  the  builtin command rreettuurrnn is executed in a function, the function
+       completes and execution resumes with the next command after  the  func-
+       tion call.  Any command associated with the RREETTUURRNN trap is executed be-
+       fore execution resumes.  When a function completes, the values  of  the
+       positional  parameters  and the special parameter ## are restored to the
+       values they had prior to the function's execution.
+
+       Function names and definitions may be listed with the --ff option to  the
+       ddeeccllaarree or ttyyppeesseett builtin commands.  The --FF option to ddeeccllaarree or ttyyppee--
+       sseett will list the function names only (and optionally the  source  file
+       and  line  number, if the eexxttddeebbuugg shell option is enabled).  Functions
+       may be exported so that child shell processes (those created when  exe-
+       cuting  a  separate  shell  invocation) automatically have them defined
+       with the --ff option to the eexxppoorrtt builtin.  A function definition may be
+       deleted using the --ff option to the uunnsseett builtin.
+
+       Functions may be recursive.  The FFUUNNCCNNEESSTT variable may be used to limit
+       the depth of the function call stack and restrict the number  of  func-
+       tion invocations.  By default, no limit is imposed on the number of re-
+       cursive calls.

+       The shell allows arithmetic expressions to be evaluated, under  certain
+       circumstances  (see  the  lleett and ddeeccllaarree builtin commands, the (((( com-
+       pound command, and AArriitthhmmeettiicc EExxppaannssiioonn).  Evaluation is done in fixed-
+       width  integers  with  no  check  for overflow, though division by 0 is
+       trapped and flagged as an error.  The operators and  their  precedence,
+       associativity,  and values are the same as in the C language.  The fol-
+       lowing list of operators is grouped into levels of equal-precedence op-
+       erators.  The levels are listed in order of decreasing precedence.

+       Shell  variables  are  allowed as operands; parameter expansion is per-
+       formed before the expression is evaluated.  Within an expression, shell
+       variables  may  also  be referenced by name without using the parameter
+       expansion syntax.  A shell variable that is null or unset evaluates  to
+       0 when referenced by name without using the parameter expansion syntax.
+       The value of a variable is evaluated as an arithmetic  expression  when
+       it  is  referenced, or when a variable which has been given the _i_n_t_e_g_e_r
+       attribute using ddeeccllaarree --ii is assigned a value.  A null value evaluates
+       to  0.   A shell variable need not have its _i_n_t_e_g_e_r attribute turned on
+       to be used in an expression.
+
+       Integer constants follow the C language definition, without suffixes or
+       character constants.  Constants with a leading 0 are interpreted as oc-
+       tal numbers.  A leading 0x or 0X denotes hexadecimal.  Otherwise,  num-
+       bers  take the form [_b_a_s_e_#]n, where the optional _b_a_s_e is a decimal num-
+       ber between 2 and 64 representing the arithmetic base, and _n is a  num-
+       ber  in  that  base.   If _b_a_s_e_# is omitted, then base 10 is used.  When
+       specifying _n, if a non-digit is required, the digits greater than 9 are
+       represented  by the lowercase letters, the uppercase letters, @, and _,
+       in that order.  If _b_a_s_e is less than or equal to 36, lowercase and  up-
+       percase  letters  may  be used interchangeably to represent numbers be-
+       tween 10 and 35.
+
+       Operators are evaluated in order  of  precedence.   Sub-expressions  in
+       parentheses  are  evaluated first and may override the precedence rules
+       above.

+       Conditional expressions are used by the [[[[  compound  command  and  the
+       tteesstt  and [[ builtin commands to test file attributes and perform string
+       and arithmetic comparisons.  The tteesstt and [[  commands  determine  their
+       behavior  based  on  the  number  of arguments; see the descriptions of
+       those commands for any other command-specific actions.
+
+       Expressions are formed from the following unary  or  binary  primaries.
+       BBaasshh  handles several filenames specially when they are used in expres-
+       sions.  If the operating system on which bbaasshh is running provides these
+       special  files,  bash will use them; otherwise it will emulate them in-
+       ternally with this behavior: If any _f_i_l_e argument to one  of  the  pri-
+       maries is of the form _/_d_e_v_/_f_d_/_n, then file descriptor _n is checked.  If
+       the _f_i_l_e argument to  one  of  the  primaries  is  one  of  _/_d_e_v_/_s_t_d_i_n,
+       _/_d_e_v_/_s_t_d_o_u_t,  or _/_d_e_v_/_s_t_d_e_r_r, file descriptor 0, 1, or 2, respectively,
+       is checked.
+
+       Unless otherwise specified, primaries that operate on files follow sym-
+       bolic links and operate on the target of the link, rather than the link
+       itself.
+
+       When used with [[[[, the << and >> operators sort  lexicographically  using
+       the current locale.  The tteesstt command sorts using ASCII ordering.

+
+SSIIMMPPLLEE CCOOMMMMAANNDD EEXXPPAANNSSIIOONN
+       When a simple command is executed, the shell performs the following ex-
+       pansions,  assignments,  and  redirections,  from left to right, in the
+       following order.
+
+       1.     The words that the parser has  marked  as  variable  assignments
+              (those  preceding  the  command name) and redirections are saved
+              for later processing.
+
+       2.     The words that are not variable assignments or redirections  are
+              expanded.   If  any words remain after expansion, the first word
+              is taken to be the name of the command and the  remaining  words
+              are the arguments.
+
+       3.     Redirections are performed as described above under RREEDDIIRREECCTTIIOONN.
+
+       4.     The text after the == in each variable assignment undergoes tilde
+              expansion, parameter expansion, command substitution, arithmetic
+              expansion,  and quote removal before being assigned to the vari-
+              able.
+
+       If no command name results, the variable assignments affect the current
+       shell  environment.   In  the case of such a command (one that consists
+       only of assignment statements and redirections), assignment  statements
+       are  performed before redirections.  Otherwise, the variables are added
+       to the environment of the executed command and do not affect  the  cur-
+       rent shell environment.  If any of the assignments attempts to assign a
+       value to a readonly variable, an error occurs, and  the  command  exits
+       with a non-zero status.
+
+       If  no command name results, redirections are performed, but do not af-
+       fect the current shell environment.  A  redirection  error  causes  the
+       command to exit with a non-zero status.
+
+       If  there is a command name left after expansion, execution proceeds as
+       described below.  Otherwise, the command exits.  If one of  the  expan-
+       sions  contained a command substitution, the exit status of the command
+       is the exit status of the  last  command  substitution  performed.   If
+       there were no command substitutions, the command exits with a status of
+       zero.
+
+CCOOMMMMAANNDD EEXXEECCUUTTIIOONN
+       After a command has been split into words, if it results  in  a  simple
+       command  and  an  optional list of arguments, the following actions are
+       taken.
+
+       If the command name contains no slashes, the shell attempts  to  locate
+       it.   If  there  exists a shell function by that name, that function is
+       invoked as described above in FFUUNNCCTTIIOONNSS.  If the name does not match  a
+       function,  the shell searches for it in the list of shell builtins.  If
+       a match is found, that builtin is invoked.
+
+       If the name is neither a shell function nor a builtin, and contains  no
+       slashes,  bbaasshh  searches  each element of the PPAATTHH for a directory con-
+       taining an executable file by that name.  BBaasshh uses a hash table to re-
+       member  the  full  pathnames  of executable files (see hhaasshh under SSHHEELLLL
+       BBUUIILLTTIINN CCOOMMMMAANNDDSS below).  A full search of the directories in  PPAATTHH  is
+       performed  only  if the command is not found in the hash table.  If the
+       search is unsuccessful, the shell searches for a defined shell function
+       named ccoommmmaanndd__nnoott__ffoouunndd__hhaannddllee.  If that function exists, it is invoked
+       in a separate execution environment with the original command  and  the
+       original  command's arguments as its arguments, and the function's exit
+       status becomes the exit status of that subshell.  If that  function  is
+       not defined, the shell prints an error message and returns an exit sta-
+       tus of 127.
+
+       If the search is successful, or if the command  name  contains  one  or
+       more slashes, the shell executes the named program in a separate execu-
+       tion environment.  Argument 0 is set to the name given, and the remain-
+       ing arguments to the command are set to the arguments given, if any.
+
+       If  this  execution fails because the file is not in executable format,
+       and the file is not a directory, it is assumed to be a _s_h_e_l_l _s_c_r_i_p_t,  a
+       file containing shell commands, and the shell creates a new instance of
+       itself to execute it.  This subshell reinitializes itself, so that  the
+       effect is as if a new shell had been invoked to handle the script, with
+       the exception that the locations of commands remembered by  the  parent
+       (see  hhaasshh  below  under  SSHHEELLLL  BBUUIILLTTIINN  CCOOMMMMAANNDDSS) are retained by the
+       child.
+
+       If the program is a file beginning with ##!!, the remainder of the  first
+       line  specifies an interpreter for the program.  The shell executes the
+       specified interpreter on operating systems that do not handle this exe-
+       cutable format themselves.  The arguments to the interpreter consist of
+       a single optional argument following the interpreter name on the  first
+       line  of  the program, followed by the name of the program, followed by
+       the command arguments, if any.

+       The shell has an _e_x_e_c_u_t_i_o_n _e_n_v_i_r_o_n_m_e_n_t, which consists of  the  follow-
+       ing:
+
+       +o      open  files inherited by the shell at invocation, as modified by
+              redirections supplied to the eexxeecc builtin
+
+       +o      the current working directory as set by ccdd, ppuusshhdd, or  ppooppdd,  or
+              inherited by the shell at invocation
+
+       +o      the  file  creation  mode mask as set by uummaasskk or inherited from
+              the shell's parent
+
+       +o      current traps set by ttrraapp
+
+       +o      shell parameters that are set by variable assignment or with sseett

+
+       +o      shell  functions  defined during execution or inherited from the

+
+       +o      shell aliases defined with aalliiaass
+
+       +o      various  process  IDs,  including  those of background jobs, the
+              value of $$$$, and the value of PPPPIIDD
+
+       When a simple command other than a builtin or shell function is  to  be
+       executed,  it  is invoked in a separate execution environment that con-
+       sists of the following.  Unless otherwise noted, the values are  inher-
+       ited from the shell.
+
+
+       +o      the  shell's  open  files,  plus any modifications and additions
+              specified by redirections to the command
+
+       +o      the current working directory
+
+       +o      the file creation mode mask
+
+       +o      shell variables and functions  marked  for  export,  along  with
+              variables exported for the command, passed in the environment
+
+       +o      traps caught by the shell are reset to the values inherited from
+              the shell's parent, and traps ignored by the shell are ignored
+
+       A command invoked  in  this  separate  environment  cannot  affect  the
+       shell's execution environment.
+
+       A _s_u_b_s_h_e_l_l is a copy of the shell process.
+
+       Command  substitution, commands grouped with parentheses, and asynchro-
+       nous commands are invoked in a subshell environment that is a duplicate
+       of the shell environment, except that traps caught by the shell are re-
+       set to the values that the shell inherited from its parent  at  invoca-
+       tion.  Builtin commands that are invoked as part of a pipeline are also
+       executed in a subshell environment.  Changes made to the subshell envi-
+       ronment cannot affect the shell's execution environment.
+
+       Subshells spawned to execute command substitutions inherit the value of
+       the --ee option from the parent shell.  When  not  in  _p_o_s_i_x  _m_o_d_e,  bbaasshh
+       clears the --ee option in such subshells.
+
+       If  a command is followed by a && and job control is not active, the de-
+       fault standard input for the command is the empty file _/_d_e_v_/_n_u_l_l.  Oth-
+       erwise,  the invoked command inherits the file descriptors of the call-
+       ing shell as modified by redirections.
+
+EENNVVIIRROONNMMEENNTT
+       When a program is invoked it is given an array of  strings  called  the
+       _e_n_v_i_r_o_n_m_e_n_t.   This  is  a  list  of  _n_a_m_e-_v_a_l_u_e  pairs,  of  the  form
+       _n_a_m_e=_v_a_l_u_e.
+
+       The shell provides several ways to manipulate the environment.  On  in-
+       vocation,  the  shell scans its own environment and creates a parameter
+       for each name found, automatically marking it for _e_x_p_o_r_t to child  pro-
+       cesses.  Executed commands inherit the environment.  The eexxppoorrtt and ddee--
+       ccllaarree --xx commands allow parameters and functions to  be  added  to  and
+       deleted from the environment.  If the value of a parameter in the envi-
+       ronment is modified, the new value becomes part of the environment, re-
+       placing  the  old.   The  environment inherited by any executed command
+       consists of the shell's initial environment, whose values may be  modi-
+       fied  in  the  shell, less any pairs removed by the uunnsseett command, plus
+       any additions via the eexxppoorrtt and ddeeccllaarree --xx commands.
+
+       The environment for any _s_i_m_p_l_e _c_o_m_m_a_n_d or  function  may  be  augmented
+       temporarily  by  prefixing  it with parameter assignments, as described
+       above in PPAARRAAMMEETTEERRSS.  These assignment statements affect only the envi-
+       ronment seen by that command.
+
+       If  the  --kk option is set (see the sseett builtin command below), then _a_l_l
+       parameter assignments are placed in the environment for a command,  not
+       just those that precede the command name.
+
+       When  bbaasshh  invokes  an  external command, the variable __ is set to the
+       full filename of the command and passed to that command in its environ-
+       ment.
+
+EEXXIITT SSTTAATTUUSS
+       The  exit  status  of  an executed command is the value returned by the
+       _w_a_i_t_p_i_d system call or equivalent function.  Exit statuses fall between
+       0  and  255, though, as explained below, the shell may use values above
+       125 specially.  Exit statuses from shell builtins and compound commands
+       are also limited to this range.  Under certain circumstances, the shell
+       will use special values to indicate specific failure modes.
+
+       For the shell's purposes, a command which exits with a zero exit status
+       has  succeeded.   An exit status of zero indicates success.  A non-zero
+       exit status indicates failure.  When a command terminates  on  a  fatal
+       signal _N, bbaasshh uses the value of 128+_N as the exit status.
+
+       If  a command is not found, the child process created to execute it re-
+       turns a status of 127.  If a command is found but  is  not  executable,
+       the return status is 126.
+
+       If a command fails because of an error during expansion or redirection,
+       the exit status is greater than zero.
+
+       Shell builtin commands return a status of 0 (_t_r_u_e) if  successful,  and
+       non-zero  (_f_a_l_s_e)  if an error occurs while they execute.  All builtins
+       return an exit status of 2 to indicate incorrect usage,  generally  in-
+       valid options or missing arguments.
+
+       The exit status of the last command is available in the special parame-
+       ter $?.
+
+       BBaasshh itself returns the exit status of the last command  executed,  un-
+       less  a  syntax  error  occurs,  in which case it exits with a non-zero
+       value.  See also the eexxiitt builtin command below.
+
+SSIIGGNNAALLSS
+       When bbaasshh is interactive, in the  absence  of  any  traps,  it  ignores
+       SSIIGGTTEERRMM (so that kkiillll 00 does not kill an interactive shell), and SSIIGGIINNTT
+       is caught and handled (so that the wwaaiitt builtin is interruptible).   In
+       all cases, bbaasshh ignores SSIIGGQQUUIITT.  If job control is in effect, bbaasshh ig-
+       nores SSIIGGTTTTIINN, SSIIGGTTTTOOUU, and SSIIGGTTSSTTPP.
+
+       Non-builtin commands run by bbaasshh have signal handlers set to the values
+       inherited by the shell from its parent.  When job control is not in ef-
+       fect, asynchronous commands ignore SSIIGGIINNTT and SSIIGGQQUUIITT  in  addition  to
+       these  inherited handlers.  Commands run as a result of command substi-
+       tution ignore the keyboard-generated job control signals SSIIGGTTTTIINN, SSIIGGTT--
+       TTOOUU, and SSIIGGTTSSTTPP.
+
+       The  shell  exits by default upon receipt of a SSIIGGHHUUPP.  Before exiting,
+       an interactive shell  resends  the  SSIIGGHHUUPP  to  all  jobs,  running  or
+       stopped.  Stopped jobs are sent SSIIGGCCOONNTT to ensure that they receive the
+       SSIIGGHHUUPP.  To prevent the shell from sending the signal to  a  particular
+       job,  it  should be removed from the jobs table with the ddiissoowwnn builtin
+       (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below) or marked to not receive SSIIGGHHUUPP  us-
+       ing ddiissoowwnn --hh.
+
+       If  the  hhuuppoonneexxiitt  shell  option has been set with sshhoopptt, bbaasshh sends a
+       SSIIGGHHUUPP to all jobs when an interactive login shell exits.
+
+       If bbaasshh is waiting for a command to complete and receives a signal  for
+       which a trap has been set, the trap will not be executed until the com-
+       mand completes.  When bbaasshh is waiting for an asynchronous  command  via
+       the  wwaaiitt  builtin, the reception of a signal for which a trap has been
+       set will cause the wwaaiitt builtin to return immediately with an exit sta-
+       tus greater than 128, immediately after which the trap is executed.
+
+       When  job  control is not enabled, and bbaasshh is waiting for a foreground
+       command to complete, the shell receives keyboard-generated signals such
+       as  SSIIGGIINNTT (usually generated by ^^CC) that users commonly intend to send
+       to that command.  This happens because the shell and the command are in
+       the same process group as the terminal, and ^^CC sends SSIIGGIINNTT to all pro-
+       cesses in that process group.
+
+       When bbaasshh is running without job control enabled  and  receives  SSIIGGIINNTT
+       while  waiting for a foreground command, it waits until that foreground
+       command terminates and then decides what to do about the SSIIGGIINNTT:
+
+       1.     If the command terminates due to the SSIIGGIINNTT, bbaasshh concludes that
+              the  user meant to end the entire script, and acts on the SSIIGGIINNTT
+              (e.g., by running a SSIIGGIINNTT trap or exiting itself);
+
+       2.     If the command does not terminate due  to  SSIIGGIINNTT,  the  program
+              handled  the  SSIIGGIINNTT itself and did not treat it as a fatal sig-
+              nal.  In that case, bbaasshh does not treat SSIIGGIINNTT as a  fatal  sig-
+              nal,  either,  instead assuming that the SSIIGGIINNTT was used as part
+              of the program's normal operation (e.g., emacs uses it to  abort
+              editing commands) or deliberately discarded.  However, bbaasshh will
+              run any trap set on SSIIGGIINNTT, as it does with  any  other  trapped
+              signal  it  receives while it is waiting for the foreground com-
+              mand to complete, for compatibility.
+
+JJOOBB CCOONNTTRROOLL
+       _J_o_b _c_o_n_t_r_o_l refers to the ability to selectively stop (_s_u_s_p_e_n_d) the ex-
+       ecution  of  processes and continue (_r_e_s_u_m_e) their execution at a later
+       point.  A user typically employs this facility via an  interactive  in-
+       terface  supplied  jointly  by  the  operating system kernel's terminal
+       driver and bbaasshh.
+
+       The shell associates a _j_o_b with each pipeline.  It  keeps  a  table  of
+       currently  executing  jobs,  which may be listed with the jjoobbss command.
+       When bbaasshh starts a job asynchronously (in the _b_a_c_k_g_r_o_u_n_d), it prints  a
+       line that looks like:
+
+              [1] 25647
+
+       indicating that this job is job number 1 and that the process ID of the
+       last process in the pipeline associated with this job is 25647.  All of
+       the  processes  in a single pipeline are members of the same job.  BBaasshh
+       uses the _j_o_b abstraction as the basis for job control.
+
+       To facilitate the implementation of the user interface to job  control,
+       the operating system maintains the notion of a _c_u_r_r_e_n_t _t_e_r_m_i_n_a_l _p_r_o_c_e_s_s
+       _g_r_o_u_p _I_D.  Members of this process group (processes whose process group
+       ID is equal to the current terminal process group ID) receive keyboard-
+       generated signals such as SSIIGGIINNTT.  These processes are said  to  be  in
+       the  _f_o_r_e_g_r_o_u_n_d.  _B_a_c_k_g_r_o_u_n_d processes are those whose process group ID
+       differs from the terminal's; such processes are immune to keyboard-gen-
+       erated signals.  Only foreground processes are allowed to read from or,
+       if the user so specifies with  stty  tostop,  write  to  the  terminal.
+       Background  processes  which  attempt  to read from (write to when stty
+       tostop is in effect) the terminal are sent a SSIIGGTTTTIINN  ((SSIIGGTTTTOOUU))  signal
+       by  the  kernel's  terminal  driver, which, unless caught, suspends the
+       process.
+
+       If the operating system on which bbaasshh is running supports job  control,
+       bbaasshh contains facilities to use it.  Typing the _s_u_s_p_e_n_d character (typ-
+       ically ^^ZZ, Control-Z) while a process is running causes that process to
+       be  stopped  and  returns  control to bbaasshh.  Typing the _d_e_l_a_y_e_d _s_u_s_p_e_n_d
+       character (typically ^^YY, Control-Y) causes the process  to  be  stopped
+       when it attempts to read input from the terminal, and control to be re-
+       turned to bbaasshh.  The user may then manipulate the state  of  this  job,
+       using  the  bbgg command to continue it in the background, the ffgg command
+       to continue it in the foreground, or the kkiillll command to kill it.  A ^^ZZ
+       takes effect immediately, and has the additional side effect of causing
+       pending output and typeahead to be discarded.
+
+       There are a number of ways to refer to a job in the shell.  The charac-
+       ter  %%  introduces  a job specification (_j_o_b_s_p_e_c).  Job number _n may be
+       referred to as %%nn.  A job may also be referred to using a prefix of the
+       name used to start it, or using a substring that appears in its command
+       line.  For example, %%ccee refers to a stopped job whose command name  be-
+       gins  with  ccee.  If a prefix matches more than one job, bbaasshh reports an
+       error.  Using %%??ccee, on the other hand, refers to any job containing the
+       string  ccee in its command line.  If the substring matches more than one
+       job, bbaasshh reports an error.  The symbols %%%% and %%++ refer to the shell's
+       notion  of  the _c_u_r_r_e_n_t _j_o_b, which is the last job stopped while it was
+       in the foreground or started in the background.  The _p_r_e_v_i_o_u_s  _j_o_b  may
+       be  referenced  using %%--.  If there is only a single job, %%++ and %%-- can
+       both be used to refer to that job.  In output pertaining to jobs (e.g.,
+       the output of the jjoobbss command), the current job is always flagged with
+       a ++, and the previous job with a --.  A single % (with  no  accompanying
+       job specification) also refers to the current job.
+
+       Simply  naming a job can be used to bring it into the foreground: %%11 is
+       a synonym for ````ffgg %%11'''', bringing job 1 from the  background  into  the
+       foreground.   Similarly,  ````%%11  &&''''  resumes  job  1 in the background,
+       equivalent to ````bbgg %%11''''.
+
+       The shell learns immediately whenever a job changes  state.   Normally,
+       bbaasshh waits until it is about to print a prompt before reporting changes
+       in a job's status so as to not interrupt any other output.  If  the  --bb
+       option to the sseett builtin command is enabled, bbaasshh reports such changes
+       immediately.  Any trap on SSIIGGCCHHLLDD is executed for each child  that  ex-
+       its.
+
+       If  an  attempt to exit bbaasshh is made while jobs are stopped (or, if the
+       cchheecckkjjoobbss shell option has been enabled using the sshhoopptt  builtin,  run-
+       ning), the shell prints a warning message, and, if the cchheecckkjjoobbss option
+       is enabled, lists the jobs and their statuses.  The  jjoobbss  command  may
+       then  be  used to inspect their status.  If a second attempt to exit is
+       made without an intervening command, the shell does not  print  another
+       warning, and any stopped jobs are terminated.
+
+       When  the shell is waiting for a job or process using the wwaaiitt builtin,
+       and job control is enabled, wwaaiitt  will  return  when  the  job  changes
+       state.  The --ff option causes wwaaiitt to wait until the job or process ter-
+       minates before returning.
+
+PPRROOMMPPTTIINNGG
+       When executing interactively, bbaasshh displays the primary prompt PPSS11 when
+       it  is  ready  to  read a command, and the secondary prompt PPSS22 when it
+       needs more input to complete a command.  BBaasshh  displays  PPSS00  after  it
+       reads  a  command  but  before  executing it.  BBaasshh displays PPSS44 as de-
+       scribed above before tracing each command when the  --xx  option  is  en-
+       abled.   BBaasshh allows these prompt strings to be customized by inserting
+       a number of backslash-escaped special characters that  are  decoded  as
+       follows:
+              \\aa     an ASCII bell character (07)
+              \\dd     the  date  in "Weekday Month Date" format (e.g., "Tue May
+                     26")
+              \\DD{{_f_o_r_m_a_t}}
+                     the _f_o_r_m_a_t is passed to _s_t_r_f_t_i_m_e(3) and the result is in-
+                     serted into the prompt string; an empty _f_o_r_m_a_t results in
+                     a locale-specific time representation.   The  braces  are
+                     required
+              \\ee     an ASCII escape character (033)

+       The command number and the history number are  usually  different:  the
+       history  number of a command is its position in the history list, which
+       may include commands restored from the history file  (see  HHIISSTTOORRYY  be-
+       low),  while the command number is the position in the sequence of com-
+       mands executed during the current shell session.  After the  string  is
+       decoded,  it is expanded via parameter expansion, command substitution,
+       arithmetic expansion, and quote removal, subject to the  value  of  the
+       pprroommppttvvaarrss shell option (see the description of the sshhoopptt command under
+       SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below).  This can have unwanted side effects  if
+       escaped  portions  of  the string appear within command substitution or
+       contain characters special to word expansion.

+       This is the library that handles reading input when using  an  interac-
+       tive shell, unless the ----nnooeeddiittiinngg option is given at shell invocation.
+       Line editing is also used when using the --ee option to the rreeaadd builtin.
+       By default, the line editing commands are similar to those of Emacs.  A
+       vi-style line editing interface is also available.  Line editing can be
+       enabled  at  any  time  using  the --oo eemmaaccss or --oo vvii options to the sseett
+       builtin (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below).  To turn off  line  editing
+       after  the  shell  is running, use the ++oo eemmaaccss or ++oo vvii options to the
+       sseett builtin.
+
+   RReeaaddlliinnee NNoottaattiioonn
+       In this section, the Emacs-style notation is used to denote keystrokes.
+       Control  keys  are  denoted by C-_k_e_y, e.g., C-n means Control-N.  Simi-
+       larly, _m_e_t_a keys are denoted by M-_k_e_y, so M-x means Meta-X.   (On  key-
+       boards  without a _m_e_t_a key, M-_x means ESC _x, i.e., press the Escape key
+       then the _x key.  This makes ESC the _m_e_t_a _p_r_e_f_i_x.  The combination M-C-_x
+       means  ESC-Control-_x, or press the Escape key then hold the Control key
+       while pressing the _x key.)
+
+       Readline commands may be given numeric _a_r_g_u_m_e_n_t_s, which normally act as
+       a  repeat  count.   Sometimes,  however, it is the sign of the argument
+       that is significant.  Passing a negative argument  to  a  command  that
+       acts  in the forward direction (e.g., kkiillll--lliinnee) causes that command to
+       act in a backward direction.  Commands whose  behavior  with  arguments
+       deviates from this are noted below.
+
+       When  a command is described as _k_i_l_l_i_n_g text, the text deleted is saved
+       for possible future retrieval (_y_a_n_k_i_n_g).  The killed text is saved in a
+       _k_i_l_l _r_i_n_g.  Consecutive kills cause the text to be accumulated into one
+       unit, which can be yanked all at once.  Commands which do not kill text
+       separate the chunks of text on the kill ring.
+
+   RReeaaddlliinnee IInniittiiaalliizzaattiioonn
+       Readline  is  customized  by putting commands in an initialization file
+       (the _i_n_p_u_t_r_c file).  The name of this file is taken from the  value  of
+       the IINNPPUUTTRRCC variable.  If that variable is unset, the default is _~_/_._i_n_-
+       _p_u_t_r_c.  If that file  does not exist or cannot be  read,  the  ultimate
+       default  is  _/_e_t_c_/_i_n_p_u_t_r_c.   When a program which uses the readline li-
+       brary starts up, the initialization file is read, and the key  bindings
+       and  variables  are set.  There are only a few basic constructs allowed
+       in the readline initialization file.  Blank lines are  ignored.   Lines
+       beginning  with  a  ##  are comments.  Lines beginning with a $$ indicate
+       conditional constructs.  Other lines denote key bindings  and  variable
+       settings.
+
+       The  default  key-bindings  may be changed with an _i_n_p_u_t_r_c file.  Other
+       programs that use this library may add their own commands and bindings.
+
+       For example, placing
+
+              M-Control-u: universal-argument
+       or
+              C-Meta-u: universal-argument
+       into the _i_n_p_u_t_r_c would make M-C-u execute the readline command  _u_n_i_v_e_r_-
+       _s_a_l_-_a_r_g_u_m_e_n_t.
+
+       The  following  symbolic  character  names are recognized: _R_U_B_O_U_T, _D_E_L,
+       _E_S_C, _L_F_D, _N_E_W_L_I_N_E, _R_E_T, _R_E_T_U_R_N, _S_P_C, _S_P_A_C_E, and _T_A_B.
+
+       In addition to command names, readline allows keys to  be  bound  to  a
+       string that is inserted when the key is pressed (a _m_a_c_r_o).
+
+   RReeaaddlliinnee KKeeyy BBiinnddiinnggss
+       The  syntax for controlling key bindings in the _i_n_p_u_t_r_c file is simple.
+       All that is required is the name of the command or the text of a  macro
+       and a key sequence to which it should be bound.  The name may be speci-
+       fied in one of two ways: as a symbolic key name, possibly with _M_e_t_a_- or
+       _C_o_n_t_r_o_l_- prefixes, or as a key sequence.
+
+       When using the form kkeeyynnaammee:_f_u_n_c_t_i_o_n_-_n_a_m_e or _m_a_c_r_o, _k_e_y_n_a_m_e is the name
+       of a key spelled out in English.  For example:
+
+              Control-u: universal-argument
+              Meta-Rubout: backward-kill-word
+              Control-o: "> output"
+
+       In the above example, _C_-_u is bound to the function  uunniivveerrssaall--aarrgguummeenntt,
+       _M_-_D_E_L  is bound to the function bbaacckkwwaarrdd--kkiillll--wwoorrdd, and _C_-_o is bound to
+       run the macro expressed on the right hand side (that is, to insert  the
+       text ``> output'' into the line).
+
+       In  the  second  form,  ""kkeeyysseeqq"":_f_u_n_c_t_i_o_n_-_n_a_m_e or _m_a_c_r_o, kkeeyysseeqq differs
+       from kkeeyynnaammee above in that strings denoting an entire key sequence  may
+       be  specified  by  placing the sequence within double quotes.  Some GNU
+       Emacs style key escapes can be used, as in the following  example,  but
+       the symbolic character names are not recognized.
+
+              "\C-u": universal-argument
+              "\C-x\C-r": re-read-init-file
+              "\e[11~": "Function Key 1"
+
+       In this example, _C_-_u is again bound to the function uunniivveerrssaall--aarrgguummeenntt.
+       _C_-_x _C_-_r is bound to the function rree--rreeaadd--iinniitt--ffiillee, and _E_S_C _[ _1 _1 _~  is
+       bound to insert the text ``Function Key 1''.
+
+       The full set of GNU Emacs style escape sequences is
+              \\CC--    control prefix
+              \\MM--    meta prefix
+              \\ee     an escape character
+              \\\\     backslash
+              \\""     literal "
+              \\''     literal '
+
+       In  addition  to  the GNU Emacs style escape sequences, a second set of
+       backslash escapes is available:
+              \\aa     alert (bell)
+              \\bb     backspace
+              \\dd     delete
+              \\ff     form feed
+              \\nn     newline
+              \\rr     carriage return
+              \\tt     horizontal tab
+              \\vv     vertical tab
+              \\_n_n_n   the eight-bit character whose value is  the  octal  value
+                     _n_n_n (one to three digits)
+              \\xx_H_H   the  eight-bit  character  whose value is the hexadecimal
+                     value _H_H (one or two hex digits)
+
+       When entering the text of a macro, single or double quotes must be used
+       to indicate a macro definition.  Unquoted text is assumed to be a func-
+       tion name.  In the macro body, the backslash  escapes  described  above
+       are  expanded.   Backslash  will quote any other character in the macro
+       text, including " and '.
+
+       BBaasshh allows the current readline key bindings to be displayed or  modi-
+       fied  with  the bbiinndd builtin command.  The editing mode may be switched
+       during interactive use by using the --oo option to the sseett  builtin  com-
+       mand (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below).
+
+   RReeaaddlliinnee VVaarriiaabblleess
+       Readline has variables that can be used to further customize its behav-
+       ior.  A variable may be set in the _i_n_p_u_t_r_c file with a statement of the
+       form
+
+              sseett _v_a_r_i_a_b_l_e_-_n_a_m_e _v_a_l_u_e
+       or using the bbiinndd builtin command (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below).
+
+       Except  where  noted,  readline variables can take the values OOnn or OOffff
+       (without regard to case).  Unrecognized  variable  names  are  ignored.
+       When  a variable value is read, empty or null values, "on" (case-insen-
+       sitive), and "1" are equivalent to OOnn.  All other values are equivalent
+       to OOffff.  The variables and their default values are:
+
+       aaccttiivvee--rreeggiioonn--ssttaarrtt--ccoolloorr
+              A  string  variable  that controls the text color and background
+              when displaying the text in the active region (see the  descrip-
+              tion  of eennaabbllee--aaccttiivvee--rreeggiioonn below).  This string must not take
+              up any physical character positions on the display, so it should
+              consist  only of terminal escape sequences.  It is output to the
+              terminal before displaying the text in the active region.   This
+              variable  is  reset  to  the default value whenever the terminal
+              type changes.  The default value is the  string  that  puts  the
+              terminal  in standout mode, as obtained from the terminal's ter-
+              minfo description.  A sample value might be "\e[01;33m".
+       aaccttiivvee--rreeggiioonn--eenndd--ccoolloorr
+              A string  variable  that  "undoes"  the  effects  of  aaccttiivvee--rree--
+              ggiioonn--ssttaarrtt--ccoolloorr  and restores "normal" terminal display appear-
+              ance after displaying text in the active  region.   This  string
+              must  not  take  up any physical character positions on the dis-
+              play, so it should consist only of  terminal  escape  sequences.
+              It  is  output  to the terminal after displaying the text in the
+              active region.  This variable is  reset  to  the  default  value
+              whenever  the  terminal  type changes.  The default value is the
+              string that restores the terminal from  standout  mode,  as  ob-
+              tained from the terminal's terminfo description.  A sample value
+              might be "\e[0m".
+       bbeellll--ssttyyllee ((aauuddiibbllee))
+              Controls what happens when readline wants to ring  the  terminal
+              bell.  If set to nnoonnee, readline never rings the bell.  If set to
+              vviissiibbllee, readline uses a visible bell if one is  available.   If
+              set to aauuddiibbllee, readline attempts to ring the terminal's bell.
+       bbiinndd--ttttyy--ssppeecciiaall--cchhaarrss ((OOnn))
+              If  set  to OOnn, readline attempts to bind the control characters
+              treated specially by the kernel's terminal driver to their read-
+              line equivalents.
+       bblliinnkk--mmaattcchhiinngg--ppaarreenn ((OOffff))
+              If set to OOnn, readline attempts to briefly move the cursor to an
+              opening parenthesis when a closing parenthesis is inserted.
+       ccoolloorreedd--ccoommpplleettiioonn--pprreeffiixx ((OOffff))
+              If set to OOnn, when listing completions,  readline  displays  the
+              common prefix of the set of possible completions using a differ-
+              ent color.  The color definitions are taken from  the  value  of
+              the LLSS__CCOOLLOORRSS environment variable.  If there is a color defini-
+              tion in $$LLSS__CCOOLLOORRSS for the custom suffix  "readline-colored-com-
+              pletion-prefix",  readline uses this color for the common prefix
+              instead of its default.
+       ccoolloorreedd--ssttaattss ((OOffff))
+              If set to OOnn, readline displays possible completions using  dif-
+              ferent  colors  to  indicate their file type.  The color defini-
+              tions are taken from the  value  of  the  LLSS__CCOOLLOORRSS  environment
+              variable.
+       ccoommmmeenntt--bbeeggiinn ((````##''''))
+              The  string  that  is  inserted when the readline iinnsseerrtt--ccoommmmeenntt
+              command is executed.  This command is bound to MM--## in emacs mode
+              and to ## in vi command mode.
+       ccoommpplleettiioonn--ddiissppllaayy--wwiiddtthh ((--11))
+              The  number  of  screen columns used to display possible matches
+              when performing completion.  The value is ignored if it is  less
+              than  0 or greater than the terminal screen width.  A value of 0
+              will cause matches to be displayed one per  line.   The  default
+              value is -1.
+       ccoommpplleettiioonn--iiggnnoorree--ccaassee ((OOffff))
+              If set to OOnn, readline performs filename matching and completion
+              in a case-insensitive fashion.
+       ccoommpplleettiioonn--mmaapp--ccaassee ((OOffff))
+              If set to OOnn, and ccoommpplleettiioonn--iiggnnoorree--ccaassee  is  enabled,  readline
+              treats  hyphens  (_-) and underscores (__) as equivalent when per-
+              forming case-insensitive filename matching and completion.
+       ccoommpplleettiioonn--pprreeffiixx--ddiissppllaayy--lleennggtthh ((00))
+              The length in characters of the common prefix of a list of  pos-
+              sible  completions that is displayed without modification.  When
+              set to a value greater than zero, common  prefixes  longer  than
+              this  value are replaced with an ellipsis when displaying possi-
+              ble completions.
+       ccoommpplleettiioonn--qquueerryy--iitteemmss ((110000))
+              This determines when the user is queried about viewing the  num-
+              ber  of  possible  completions generated by the ppoossssiibbllee--ccoommppllee--
+              ttiioonnss command.  It may be set to any integer value greater  than
+              or  equal  to  zero.   If  the number of possible completions is
+              greater than or equal to the value of  this  variable,  readline
+              will  ask whether or not the user wishes to view them; otherwise
+              they are simply listed on the  terminal.   A  zero  value  means
+              readline should never ask; negative values are treated as zero.
+       ccoonnvveerrtt--mmeettaa ((OOnn))
+              If  set  to OOnn, readline will convert characters with the eighth
+              bit set to an ASCII key sequence by stripping the eighth bit and
+              prefixing  an  escape  character (in effect, using escape as the
+              _m_e_t_a _p_r_e_f_i_x).  The default is _O_n, but readline will  set  it  to
+              _O_f_f  if the locale contains eight-bit characters.  This variable
+              is dependent on the LLCC__CCTTYYPPEE locale category, and may change  if
+              the locale is changed.
+       ddiissaabbllee--ccoommpplleettiioonn ((OOffff))
+              If set to OOnn, readline will inhibit word completion.  Completion
+              characters will be inserted into the line as if  they  had  been
+              mapped to sseellff--iinnsseerrtt.
+       eecchhoo--ccoonnttrrooll--cchhaarraacctteerrss ((OOnn))
+              When  set to OOnn, on operating systems that indicate they support
+              it, readline echoes a character corresponding to a signal gener-
+              ated from the keyboard.
+       eeddiittiinngg--mmooddee ((eemmaaccss))
+              Controls whether readline begins with a set of key bindings sim-
+              ilar to _E_m_a_c_s or _v_i.  eeddiittiinngg--mmooddee can be set to either eemmaaccss or
+              vvii.
+       eemmaaccss--mmooddee--ssttrriinngg ((@@))
+              If  the  _s_h_o_w_-_m_o_d_e_-_i_n_-_p_r_o_m_p_t variable is enabled, this string is
+              displayed immediately before the last line of the primary prompt
+              when emacs editing mode is active.  The value is expanded like a
+              key binding, so the standard set of meta- and  control  prefixes
+              and  backslash escape sequences is available.  Use the \1 and \2
+              escapes to begin and end sequences of  non-printing  characters,
+              which  can be used to embed a terminal control sequence into the
+              mode string.
+       eennaabbllee--aaccttiivvee--rreeggiioonn ((OOnn))
+              The _p_o_i_n_t is the current cursor position, and _m_a_r_k refers  to  a
+              saved  cursor  position.  The text between the point and mark is
+              referred to as the _r_e_g_i_o_n.  When this variable  is  set  to  _O_n,
+              readline  allows certain commands to designate the region as _a_c_-
+              _t_i_v_e.  When the region is active, readline highlights  the  text
+              in  the region using the value of the aaccttiivvee--rreeggiioonn--ssttaarrtt--ccoolloorr,
+              which defaults to the string that enables the terminal's  stand-
+              out  mode.   The active region shows the text inserted by brack-
+              eted-paste and any matching text found by incremental  and  non-
+              incremental history searches.
+       eennaabbllee--bbrraacckkeetteedd--ppaassttee ((OOnn))
+              When  set to OOnn, readline configures the terminal to insert each
+              paste into the editing buffer as a single string of  characters,
+              instead  of  treating each character as if it had been read from
+              the keyboard.  This prevents readline from executing any editing
+              commands bound to key sequences appearing in the pasted text.
+       eennaabbllee--kkeeyyppaadd ((OOffff))
+              When set to OOnn, readline will try to enable the application key-
+              pad when it is called.  Some systems need this to enable the ar-

+       Readline implements a facility similar in  spirit  to  the  conditional
+       compilation  features  of  the C preprocessor which allows key bindings
+       and variable settings to be performed as the result  of  tests.   There
+       are four parser directives used.
+
+       $$iiff    The  $$iiff construct allows bindings to be made based on the edit-
+              ing mode, the terminal being  used,  or  the  application  using
+              readline.  The text of the test, after any comparison operator,
+               extends  to  the  end  of  the line; unless otherwise noted, no
+              characters are required to isolate it.
+
+              mmooddee   The mmooddee== form of the  $$iiff  directive  is  used  to  test
+                     whether  readline  is  in  emacs or vi mode.  This may be
+                     used in conjunction with the sseett kkeeyymmaapp command, for  in-
+                     stance,   to  set  bindings  in  the  _e_m_a_c_s_-_s_t_a_n_d_a_r_d  and
+                     _e_m_a_c_s_-_c_t_l_x keymaps only if readline is  starting  out  in
+                     emacs mode.
+
+              tteerrmm   The  tteerrmm==  form may be used to include terminal-specific
+                     key bindings, perhaps to bind the key sequences output by
+                     the terminal's function keys.  The word on the right side
+                     of the == is tested against both the full name of the ter-
+                     minal  and  the  portion  of the terminal name before the
+                     first --.  This allows _s_u_n to match both _s_u_n and  _s_u_n_-_c_m_d,
+                     for instance.
+
+              vveerrssiioonn
+                     The  vveerrssiioonn  test  may  be  used  to perform comparisons
+                     against specific readline versions.  The vveerrssiioonn  expands
+                     to  the  current readline version.  The set of comparison
+                     operators includes ==, (and ====), !!==, <<==,  >>==,  <<,  and  >>.
+                     The  version number supplied on the right side of the op-
+                     erator consists of a major version  number,  an  optional
+                     decimal point, and an optional minor version (e.g., 77..11).
+                     If the minor version is omitted, it is assumed to  be  00.
+                     The operator may be separated from the string vveerrssiioonn and
+                     from the version number argument by whitespace.
+
+              aapppplliiccaattiioonn
+                     The aapppplliiccaattiioonn construct is used to include application-
+                     specific  settings.   Each program using the readline li-
+                     brary sets the _a_p_p_l_i_c_a_t_i_o_n _n_a_m_e,  and  an  initialization
+                     file can test for a particular value.  This could be used
+                     to bind key sequences to functions useful for a  specific
+                     program.   For instance, the following command adds a key
+                     sequence that quotes the  current  or  previous  word  in
+                     bbaasshh:
+
+                     $$iiff Bash
+                     # Quote the current or previous word
+                     "\C-xq": "\eb\"\ef\""
+                     $$eennddiiff
+
+              _v_a_r_i_a_b_l_e
+                     The _v_a_r_i_a_b_l_e construct provides simple equality tests for
+                     readline variables and values.  The permitted  comparison
+                     operators  are  _=, _=_=, and _!_=.  The variable name must be
+                     separated from the comparison operator by whitespace; the
+                     operator  may  be  separated  from the value on the right
+                     hand side by whitespace.  Both string and  boolean  vari-
+                     ables  may  be  tested.  Boolean variables must be tested
+                     against the values _o_n and _o_f_f.
+
+       $$eennddiiff This command, as seen in the previous example, terminates an $$iiff
+              command.
+
+       $$eellssee  Commands in this branch of the $$iiff directive are executed if the
+              test fails.
+
+       $$iinncclluuddee
+              This directive takes a single filename as an argument and  reads
+              commands  and bindings from that file.  For example, the follow-
+              ing directive would read _/_e_t_c_/_i_n_p_u_t_r_c:
+
+              $$iinncclluuddee  _/_e_t_c_/_i_n_p_u_t_r_c
+
+   SSeeaarrcchhiinngg
+       Readline provides commands for searching through  the  command  history
+       (see HHIISSTTOORRYY below) for lines containing a specified string.  There are
+       two search modes: _i_n_c_r_e_m_e_n_t_a_l and _n_o_n_-_i_n_c_r_e_m_e_n_t_a_l.
+
+       Incremental searches begin before the  user  has  finished  typing  the
+       search  string.  As each character of the search string is typed, read-
+       line displays the next entry from the history matching the string typed
+       so  far.   An  incremental  search  requires only as many characters as
+       needed to find the desired history entry.  The  characters  present  in
+       the  value of the iisseeaarrcchh--tteerrmmiinnaattoorrss variable are used to terminate an
+       incremental search.  If that variable has not been assigned a value the
+       Escape  and  Control-J characters will terminate an incremental search.
+       Control-G will abort an incremental search  and  restore  the  original
+       line.   When the search is terminated, the history entry containing the
+       search string becomes the current line.
+
+       To find other matching entries in the history list, type  Control-S  or
+       Control-R  as appropriate.  This will search backward or forward in the
+       history for the next entry matching the search  string  typed  so  far.
+       Any  other  key sequence bound to a readline command will terminate the
+       search and execute that command.  For instance, a _n_e_w_l_i_n_e  will  termi-
+       nate the search and accept the line, thereby executing the command from
+       the history list.
+
+       Readline remembers the last incremental search string.  If two Control-
+       Rs  are  typed without any intervening characters defining a new search
+       string, any remembered search string is used.
+
+       Non-incremental searches read the entire search string before  starting
+       to  search  for matching history lines.  The search string may be typed
+       by the user or be part of the contents of the current line.

+
+   PPrrooggrraammmmaabbllee CCoommpplleettiioonn
+       When  word  completion  is  attempted  for an argument to a command for
+       which a completion specification (a _c_o_m_p_s_p_e_c) has  been  defined  using
+       the  ccoommpplleettee  builtin (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below), the program-
+       mable completion facilities are invoked.
+
+       First, the command name is identified.  If  the  command  word  is  the
+       empty  string (completion attempted at the beginning of an empty line),
+       any compspec defined with the --EE option to  ccoommpplleettee  is  used.   If  a
+       compspec  has  been  defined  for that command, the compspec is used to
+       generate the list of possible completions for the word.  If the command
+       word  is  a full pathname, a compspec for the full pathname is searched
+       for first.  If no compspec is found for the full pathname,  an  attempt
+       is  made  to find a compspec for the portion following the final slash.
+       If those searches do not result in a  compspec,  any  compspec  defined
+       with  the --DD option to ccoommpplleettee is used as the default.  If there is no
+       default compspec, bbaasshh attempts alias expansion on the command word  as
+       a  final  resort,  and attempts to find a compspec for the command word
+       from any successful expansion.
+
+       Once a compspec has been found, it is used  to  generate  the  list  of
+       matching  words.   If a compspec is not found, the default bbaasshh comple-
+       tion as described above under CCoommpplleettiinngg is performed.
+
+       First, the actions specified by the compspec are  used.   Only  matches
+       which  are prefixed by the word being completed are returned.  When the
+       --ff or --dd option is used for filename or directory name completion,  the
+       shell variable FFIIGGNNOORREE is used to filter the matches.
+
+       Any completions specified by a pathname expansion pattern to the --GG op-
+       tion are generated next.  The words generated by the pattern  need  not
+       match  the  word being completed.  The GGLLOOBBIIGGNNOORREE shell variable is not
+       used to filter the matches, but the FFIIGGNNOORREE variable is used.
+
+       Next, the string specified as the argument to the --WW option is  consid-
+       ered.   The  string is first split using the characters in the IIFFSS spe-
+       cial variable as delimiters.  Shell quoting is honored.  Each  word  is
+       then  expanded  using  brace  expansion, tilde expansion, parameter and
+       variable expansion, command substitution, and arithmetic expansion,  as
+       described above under EEXXPPAANNSSIIOONN.  The results are split using the rules
+       described above under WWoorrdd SSpplliittttiinngg.  The results of the expansion are
+       prefix-matched against the word being completed, and the matching words
+       become the possible completions.
+
+       After these matches have been generated, any shell function or  command
+       specified  with  the --FF and --CC options is invoked.  When the command or
+       function is invoked, the CCOOMMPP__LLIINNEE, CCOOMMPP__PPOOIINNTT, CCOOMMPP__KKEEYY, and CCOOMMPP__TTYYPPEE
+       variables are assigned values as described above under SShheellll VVaarriiaabblleess.
+       If a shell function is being invoked,  the  CCOOMMPP__WWOORRDDSS  and  CCOOMMPP__CCWWOORRDD
+       variables  are  also set.  When the function or command is invoked, the
+       first argument ($$11) is the name of the command whose arguments are  be-
+       ing  completed,  the  second argument ($$22) is the word being completed,
+       and the third argument ($$33) is the word preceding the word  being  com-
+       pleted on the current command line.  No filtering of the generated com-
+       pletions against the word being completed is performed; the function or
+       command has complete freedom in generating the matches.
+
+       Any  function specified with --FF is invoked first.  The function may use
+       any of the shell facilities, including the  ccoommppggeenn  builtin  described
+       below,  to  generate the matches.  It must put the possible completions
+       in the CCOOMMPPRREEPPLLYY array variable, one per array element.
+
+       Next, any command specified with the --CC option is invoked in  an  envi-
+       ronment  equivalent to command substitution.  It should print a list of
+       completions, one per line, to the standard output.   Backslash  may  be
+       used to escape a newline, if necessary.
+
+       After  all of the possible completions are generated, any filter speci-
+       fied with the --XX option is applied to the list.  The filter is  a  pat-
+       tern  as  used  for  pathname expansion; a && in the pattern is replaced
+       with the text of the word being completed.  A literal && may be  escaped
+       with  a  backslash; the backslash is removed before attempting a match.
+       Any completion that matches the pattern will be removed from the  list.
+       A leading !! negates the pattern; in this case any completion not match-
+       ing the pattern will be removed.  If the nnooccaasseemmaattcchh  shell  option  is
+       enabled,  the  match  is performed without regard to the case of alpha-
+       betic characters.
+
+       Finally, any prefix and suffix specified with the --PP and --SS options are
+       added to each member of the completion list, and the result is returned
+       to the readline completion code as the list of possible completions.
+
+       If the previously-applied actions do not generate any matches, and  the
+       --oo  ddiirrnnaammeess  option was supplied to ccoommpplleettee when the compspec was de-
+       fined, directory name completion is attempted.
+
+       If the --oo pplluussddiirrss option was supplied to ccoommpplleettee  when  the  compspec
+       was defined, directory name completion is attempted and any matches are
+       added to the results of the other actions.
+
+       By default, if a compspec is found, whatever it generates  is  returned
+       to  the  completion  code as the full set of possible completions.  The
+       default bbaasshh completions are not attempted, and the readline default of
+       filename completion is disabled.  If the --oo bbaasshhddeeffaauulltt option was sup-
+       plied to ccoommpplleettee when the compspec was defined, the bbaasshh default  com-
+       pletions are attempted if the compspec generates no matches.  If the --oo
+       ddeeffaauulltt option was supplied to ccoommpplleettee when the compspec was  defined,
+       readline's  default  completion will be performed if the compspec (and,
+       if attempted, the default bbaasshh completions) generate no matches.
+
+       When a compspec indicates that directory name  completion  is  desired,
+       the  programmable completion functions force readline to append a slash
+       to completed names which are symbolic links to directories, subject  to
+       the  value of the mmaarrkk--ddiirreeccttoorriieess readline variable, regardless of the
+       setting of the mmaarrkk--ssyymmlliinnkkeedd--ddiirreeccttoorriieess readline variable.
+
+       There is some support for dynamically modifying completions.   This  is
+       most  useful  when used in combination with a default completion speci-
+       fied with ccoommpplleettee --DD.  It's possible for shell functions  executed  as
+       completion  handlers  to  indicate that completion should be retried by
+       returning an exit status of 124.  If a shell function returns 124,  and
+       changes the compspec associated with the command on which completion is
+       being attempted (supplied as the first argument when  the  function  is
+       executed), programmable completion restarts from the beginning, with an
+       attempt to find a new compspec for that command.  This allows a set  of
+       completions  to be built dynamically as completion is attempted, rather
+       than being loaded all at once.
+
+       For instance, assuming that there is a library of compspecs, each  kept
+       in  a  file corresponding to the name of the command, the following de-
+       fault completion function would load completions dynamically:
+
+       _completion_loader()
+       {
+            . "/etc/bash_completion.d/$1.sh" >/dev/null 2>&1 && return 124
+       }
+       complete -D -F _completion_loader -o bashdefault -o default
+
+
+HHIISSTTOORRYY
+       When the --oo hhiissttoorryy option to the sseett builtin  is  enabled,  the  shell
+       provides access to the _c_o_m_m_a_n_d _h_i_s_t_o_r_y, the list of commands previously
+       typed.  The value of the HHIISSTTSSIIZZEE variable is used  as  the  number  of
+       commands to save in a history list.  The text of the last HHIISSTTSSIIZZEE com-
+       mands (default 500) is saved.  The shell stores  each  command  in  the
+       history  list  prior to parameter and variable expansion (see EEXXPPAANNSSIIOONN
+       above) but after history expansion is performed, subject to the  values
+       of the shell variables HHIISSTTIIGGNNOORREE and HHIISSTTCCOONNTTRROOLL.
+
+       On startup, the history is initialized from the file named by the vari-
+       able HHIISSTTFFIILLEE (default _~_/_._b_a_s_h___h_i_s_t_o_r_y).  The file named by  the  value
+       of  HHIISSTTFFIILLEE  is  truncated,  if necessary, to contain no more than the
+       number of lines specified by the value of HHIISSTTFFIILLEESSIIZZEE.   If  HHIISSTTFFIILLEE--
+       SSIIZZEE  is unset, or set to null, a non-numeric value, or a numeric value
+       less than zero, the history file is not truncated.   When  the  history
+       file  is  read, lines beginning with the history comment character fol-
+       lowed immediately by a digit are interpreted as timestamps for the fol-
+       lowing history line.  These timestamps are optionally displayed depend-
+       ing on the value of the HHIISSTTTTIIMMEEFFOORRMMAATT variable.   When  a  shell  with
+       history  enabled  exits,  the  last $$HHIISSTTSSIIZZEE lines are copied from the
+       history list to $$HHIISSTTFFIILLEE.  If the hhiissttaappppeenndd shell option  is  enabled
+       (see  the description of sshhoopptt under SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below), the
+       lines are appended to the history file, otherwise the history  file  is
+       overwritten.   If  HHIISSTTFFIILLEE  is  unset,  or  if the history file is un-
+       writable, the history is not saved.  If the HHIISSTTTTIIMMEEFFOORRMMAATT variable  is
+       set,  time stamps are written to the history file, marked with the his-
+       tory comment character, so they may be preserved across shell sessions.
+       This  uses the history comment character to distinguish timestamps from
+       other history lines.  After saving the history,  the  history  file  is
+       truncated  to contain no more than HHIISSTTFFIILLEESSIIZZEE lines.  If HHIISSTTFFIILLEESSIIZZEE
+       is unset, or set to null, a non-numeric value, or a numeric value  less
+       than zero, the history file is not truncated.
+
+       The  builtin  command ffcc (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below) may be used
+       to list or edit and re-execute a portion of the history list.  The hhiiss--
+       ttoorryy  builtin may be used to display or modify the history list and ma-
+       nipulate the history file.  When  using  command-line  editing,  search
+       commands  are available in each editing mode that provide access to the
+       history list.
+
+       The shell allows control over which commands are saved on  the  history
+       list.  The HHIISSTTCCOONNTTRROOLL and HHIISSTTIIGGNNOORREE variables may be set to cause the
+       shell to save only a subset of the commands entered.  The ccmmddhhiisstt shell
+       option,  if enabled, causes the shell to attempt to save each line of a
+       multi-line command in the same history entry, adding  semicolons  where
+       necessary  to preserve syntactic correctness.  The lliitthhiisstt shell option
+       causes the shell to save the command with embedded newlines instead  of
+       semicolons.  See the description of the sshhoopptt builtin below under SSHHEELLLL
+       BBUUIILLTTIINN CCOOMMMMAANNDDSS for information on setting  and  unsetting  shell  op-
+       tions.
+
+HHIISSTTOORRYY EEXXPPAANNSSIIOONN
+       The  shell  supports a history expansion feature that is similar to the
+       history expansion in ccsshh.  This section describes what syntax  features
+       are  available.   This  feature  is  enabled by default for interactive
+       shells, and can be disabled using the ++HH option to the sseett builtin com-
+       mand (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below).  Non-interactive shells do not
+       perform history expansion by default.
+
+       History expansions introduce words from the history list into the input
+       stream,  making  it  easy to repeat commands, insert the arguments to a
+       previous command into the current input line, or fix errors in previous
+       commands quickly.
+
+       History  expansion  is  performed  immediately after a complete line is
+       read, before the shell breaks it into words, and is performed  on  each
+       line  individually  without  taking  quoting on previous lines into ac-
+       count.  It takes place in two parts.  The first is to  determine  which
+       line  from  the history list to use during substitution.  The second is
+       to select portions of that line for inclusion  into  the  current  one.
+       The  line  selected  from the history is the _e_v_e_n_t, and the portions of
+       that line that are acted upon are _w_o_r_d_s.  Various _m_o_d_i_f_i_e_r_s are  avail-
+       able  to  manipulate the selected words.  The line is broken into words
+       in the same fashion as when reading input, so that several  _m_e_t_a_c_h_a_r_a_c_-
+       _t_e_r-separated words surrounded by quotes are considered one word.  His-
+       tory expansions are introduced by the appearance of the history  expan-
+       sion  character,  which is !! by default.  Only backslash (\\) and single
+       quotes can quote the history expansion character, but the  history  ex-
+       pansion  character is also treated as quoted if it immediately precedes
+       the closing double quote in a double-quoted string.
+
+       Several characters inhibit history expansion if found immediately  fol-
+       lowing  the history expansion character, even if it is unquoted: space,
+       tab, newline, carriage return, and ==.  If the eexxttgglloobb shell  option  is
+       enabled, (( will also inhibit expansion.
+
+       Several  shell  options  settable with the sshhoopptt builtin may be used to
+       tailor the behavior of history expansion.  If the hhiissttvveerriiffyy shell  op-
+       tion  is  enabled (see the description of the sshhoopptt builtin below), and
+       rreeaaddlliinnee is being  used,  history  substitutions  are  not  immediately
+       passed  to  the  shell  parser.  Instead, the expanded line is reloaded
+       into the rreeaaddlliinnee editing buffer for further modification.  If rreeaaddlliinnee
+       is  being  used,  and  the hhiissttrreeeeddiitt shell option is enabled, a failed
+       history substitution will be reloaded into the rreeaaddlliinnee editing  buffer
+       for  correction.   The  --pp option to the hhiissttoorryy builtin command may be
+       used to see what a history expansion will do before using it.   The  --ss
+       option to the hhiissttoorryy builtin may be used to add commands to the end of
+       the history list without actually executing  them,  so  that  they  are
+       available for subsequent recall.
+
+       The  shell allows control of the various characters used by the history
+       expansion mechanism (see the description of hhiissttcchhaarrss above under SShheellll
+       VVaarriiaabblleess).   The shell uses the history comment character to mark his-
+       tory timestamps when writing the history file.

+       An event designator is a reference to a command line entry in the  his-

+       are numbered from the beginning of the line, with the first word  being

+              the search string begins with a character  that  is  part  of  a
+              word.
+       _x--_y    A range of words; `-_y' abbreviates `0-_y'.
+       **      All  of  the words but the zeroth.  This is a synonym for `_1_-_$'.
+              It is not an error to use ** if there is just  one  word  in  the
+              event; the empty string is returned in that case.
+       xx**     Abbreviates _x_-_$.
+       xx--     Abbreviates _x_-_$ like xx**, but omits the last word.  If xx is miss-
+              ing, it defaults to 0.

+              Substitute  _n_e_w  for  the  first  occurrence of _o_l_d in the event
+              line.  Any character may be used as the delimiter in place of /.
+              The  final  delimiter is optional if it is the last character of
+              the event line.  The delimiter may be quoted in _o_l_d and _n_e_w with
+              a single backslash.  If & appears in _n_e_w, it is replaced by _o_l_d.
+              A single backslash will quote the &.  If _o_l_d is null, it is  set
+              to  the last _o_l_d substituted, or, if no previous history substi-
+              tutions took place, the last _s_t_r_i_n_g in  a  !!??_s_t_r_i_n_g[[??]]   search.

+       &&      Repeat the previous substitution.
+       gg      Cause changes to be applied over the entire event line.  This is
+              used in conjunction with `::ss' (e.g.,  `::ggss//_o_l_d//_n_e_w//')  or  `::&&'.
+              If  used with `::ss', any delimiter can be used in place of /, and
+              the final delimiter is optional if it is the last  character  of
+              the event line.  An aa may be used as a synonym for gg.

+              specified, break _n levels.  _n must be >= 1.   If  _n  is  greater
+              than  the number of enclosing loops, all enclosing loops are ex-
+              ited.  The return value is 0 unless _n is  not  greater  than  or

+

+              return its exit status.  This is useful when defining a function
+              whose  name  is the same as a shell builtin, retaining the func-
+              tionality of the builtin within the function.  The ccdd builtin is
+              commonly  redefined  this  way.   The  return status is false if
+              _s_h_e_l_l_-_b_u_i_l_t_i_n is not a shell builtin command.
+
+       ccaalllleerr [_e_x_p_r]
+              Returns the context of any active subroutine call (a shell func-
+              tion or a script executed with the .. or ssoouurrccee builtins).  With-
+              out _e_x_p_r, ccaalllleerr displays the line number and source filename of
+              the  current subroutine call.  If a non-negative integer is sup-
+              plied as _e_x_p_r, ccaalllleerr displays the line number, subroutine name,
+              and  source  file  corresponding to that position in the current
+              execution call stack.  This extra information may be  used,  for
+              example,  to print a stack trace.  The current frame is frame 0.
+              The return value is 0 unless the shell is not executing  a  sub-
+              routine  call or _e_x_p_r does not correspond to a valid position in
+              the call stack.
+
+       ccdd [--LL|[--PP [--ee]] [-@]] [_d_i_r]
+              Change the current directory to _d_i_r.  if _d_i_r  is  not  supplied,
+              the  value of the HHOOMMEE shell variable is the default.  The vari-
+              able CCDDPPAATTHH defines the search path for the directory containing
+              _d_i_r:  each directory name in CCDDPPAATTHH is searched for _d_i_r.  Alter-
+              native directory names in CCDDPPAATTHH are separated by a  colon  (:).
+              A  null  directory name in CCDDPPAATTHH is the same as the current di-
+              rectory, i.e., ``..''.  If _d_i_r begins with a slash (/), then  CCDD--
+              PPAATTHH  is  not used.  The --PP option causes ccdd to use the physical
+              directory structure by resolving symbolic links while traversing
+              _d_i_r  and  before processing instances of _._. in _d_i_r (see also the
+              --PP option to the sseett builtin command); the --LL option forces sym-
+              bolic  links to be followed by resolving the link after process-
+              ing instances of _._. in _d_i_r.  If _._. appears in _d_i_r,  it  is  pro-
+              cessed  by  removing the immediately previous pathname component
+              from _d_i_r, back to a slash or the beginning of _d_i_r.   If  the  --ee
+              option  is  supplied  with --PP, and the current working directory
+              cannot be successfully determined after a  successful  directory
+              change,  ccdd will return an unsuccessful status.  On systems that
+              support it, the --@@ option presents the extended attributes asso-
+              ciated  with  a  file  as a directory.  An argument of -- is con-
+              verted to $$OOLLDDPPWWDD before the directory change is attempted.   If
+              a  non-empty  directory name from CCDDPPAATTHH is used, or if -- is the
+              first argument, and the directory change is successful, the  ab-
+              solute  pathname  of the new working directory is written to the
+              standard output.  If the directory change is successful, ccdd sets
+              the  value  of the PPWWDD environment variable to the new directory
+              name, and sets the OOLLDDPPWWDD environment variable to the  value  of
+              the  current  working  directory  before the change.  The return
+              value is true if the directory was successfully  changed;  false
+              otherwise.
+
+       ccoommmmaanndd [--ppVVvv] _c_o_m_m_a_n_d [_a_r_g ...]
+              Run  _c_o_m_m_a_n_d  with  _a_r_g_s  suppressing  the normal shell function
+              lookup.  Only builtin commands or commands found in the PPAATTHH are
+              executed.   If the --pp option is given, the search for _c_o_m_m_a_n_d is
+              performed using a default value for PPAATTHH that is  guaranteed  to
+              find  all of the standard utilities.  If either the --VV or --vv op-
+              tion is supplied, a description of _c_o_m_m_a_n_d is printed.   The  --vv
+              option  causes  a single word indicating the command or filename
+              used to invoke _c_o_m_m_a_n_d to be displayed; the --VV option produces a
+              more  verbose  description.  If the --VV or --vv option is supplied,
+              the exit status is 0 if _c_o_m_m_a_n_d was found, and  1  if  not.   If
+              neither option is supplied and an error occurred or _c_o_m_m_a_n_d can-
+              not be found, the exit status is 127.  Otherwise, the exit  sta-
+              tus of the ccoommmmaanndd builtin is the exit status of _c_o_m_m_a_n_d.
+
+       ccoommppggeenn [_o_p_t_i_o_n] [_w_o_r_d]
+              Generate  possible  completion matches for _w_o_r_d according to the
+              _o_p_t_i_o_ns, which may  be  any  option  accepted  by  the  ccoommpplleettee
+              builtin  with  the exception of --pp and --rr, and write the matches
+              to the standard output.  When using the --FF or  --CC  options,  the
+              various  shell  variables set by the programmable completion fa-
+              cilities, while available, will not have useful values.
+
+              The matches will be generated in the same way as if the program-
+              mable completion code had generated them directly from a comple-
+              tion specification with the same flags.  If _w_o_r_d  is  specified,
+              only those completions matching _w_o_r_d will be displayed.
+
+              The  return  value is true unless an invalid option is supplied,
+              or no matches were generated.

+              --pp  option  is supplied, or if no options are supplied, existing
+              completion specifications are printed in a way that allows  them
+              to be reused as input.  The --rr option removes a completion spec-
+              ification for each _n_a_m_e, or, if no _n_a_m_es are supplied, all  com-
+              pletion specifications.  The --DD option indicates that other sup-
+              plied options and actions should apply to the  ``default''  com-
+              mand  completion; that is, completion attempted on a command for
+              which no completion has previously been defined.  The --EE  option
+              indicates  that  other supplied options and actions should apply
+              to ``empty'' command completion; that is,  completion  attempted
+              on  a  blank  line.  The --II option indicates that other supplied
+              options and actions should apply to completion  on  the  initial
+              non-assignment  word  on  the line, or after a command delimiter
+              such as ;; or ||, which is usually command  name  completion.   If
+              multiple  options  are  supplied, the --DD option takes precedence
+              over --EE, and both take precedence over --II.  If any of --DD, --EE, or
+              --II  are  supplied,  any  other _n_a_m_e arguments are ignored; these
+              completions only apply to the case specified by the option.

+                      _c_o_m_m_a_n_d is executed in a subshell environment,  and  its
+                      output  is  used as the possible completions.  Arguments
+                      are passed as with the --FF option.
+              --FF _f_u_n_c_t_i_o_n
+                      The shell function _f_u_n_c_t_i_o_n is executed in  the  current
+                      shell  environment.   When the function is executed, the
+                      first argument ($$11) is the name of the command whose ar-
+                      guments are being completed, the second argument ($$22) is
+                      the word being completed, and the third argument ($$33) is
+                      the  word preceding the word being completed on the cur-
+                      rent command line.  When it finishes, the possible  com-
+                      pletions  are  retrieved from the value of the CCOOMMPPRREEPPLLYY
+                      array variable.

+                      _p_r_e_f_i_x  is  added at the beginning of each possible com-

+                      _s_u_f_f_i_x is appended to each possible completion after all
+                      other options have been applied.
+              --WW _w_o_r_d_l_i_s_t
+                      The  _w_o_r_d_l_i_s_t  is  split using the characters in the IIFFSS
+                      special variable as delimiters, and each resultant  word
+                      is  expanded.  Shell quoting is honored within _w_o_r_d_l_i_s_t,
+                      in order to provide a mechanism for the words to contain
+                      shell  metacharacters or characters in the value of IIFFSS.
+                      The possible completions are the members of  the  resul-
+                      tant list which match the word being completed.
+              --XX _f_i_l_t_e_r_p_a_t
+                      _f_i_l_t_e_r_p_a_t  is  a pattern as used for pathname expansion.
+                      It is applied to the list of possible completions gener-
+                      ated  by  the  preceding options and arguments, and each
+                      completion matching _f_i_l_t_e_r_p_a_t is removed from the  list.
+                      A  leading  !!  in _f_i_l_t_e_r_p_a_t negates the pattern; in this
+                      case, any completion not matching _f_i_l_t_e_r_p_a_t is removed.
+
+              The return value is true unless an invalid option  is  supplied,
+              an  option  other than --pp or --rr is supplied without a _n_a_m_e argu-

+              scribed  above.  The --DD option indicates that other supplied op-

+              is,  completion  attempted  on a command for which no completion
+              has previously been defined.  The --EE option indicates that other
+              supplied  options  should apply to ``empty'' command completion;
+              that is, completion attempted on a blank line.   The  --II  option
+              indicates that other supplied options should apply to completion
+              on the initial non-assignment word on the line, or after a  com-

+              Declare  variables and/or give them attributes.  If no _n_a_m_es are
+              given then display the values of variables.  The --pp option  will
+              display the attributes and values of each _n_a_m_e.  When --pp is used
+              with _n_a_m_e arguments, additional options, other than --ff  and  --FF,
+              are  ignored.   When  --pp  is supplied without _n_a_m_e arguments, it
+              will display the attributes and values of all  variables  having
+              the attributes specified by the additional options.  If no other
+              options are supplied with  --pp,  ddeeccllaarree  will  display  the  at-
+              tributes  and values of all shell variables.  The --ff option will
+              restrict the display to shell functions.  The --FF option inhibits
+              the  display of function definitions; only the function name and
+              attributes are printed.  If the eexxttddeebbuugg shell option is enabled
+              using  sshhoopptt,  the  source  file name and line number where each
+              _n_a_m_e is defined are displayed as well.  The  --FF  option  implies
+              --ff.  The --gg option forces variables to be created or modified at
+              the global scope, even when ddeeccllaarree is executed in a shell func-
+              tion.   It  is ignored in all other cases.  The --II option causes
+              local variables to inherit the attributes  (except  the  _n_a_m_e_r_e_f
+              attribute) and value of any existing variable with the same _n_a_m_e
+              at a surrounding scope.  If there is no existing  variable,  the
+              local variable is initially unset.  The following options can be
+              used to restrict output to variables with the  specified  attri-
+              bute or to give variables attributes:
+              --aa     Each  _n_a_m_e  is  an  indexed  array  variable  (see AArrrraayyss
+                     above).
+              --AA     Each _n_a_m_e is an associative array  variable  (see  AArrrraayyss
+                     above).
+              --ff     Use function names only.
+              --ii     The variable is treated as an integer; arithmetic evalua-
+                     tion (see AARRIITTHHMMEETTIICC EEVVAALLUUAATTIIOONN above) is performed  when
+                     the variable is assigned a value.
+              --ll     When  the  variable  is  assigned a value, all upper-case
+                     characters are converted to lower-case.   The  upper-case
+                     attribute is disabled.
+              --nn     Give  each  _n_a_m_e  the _n_a_m_e_r_e_f attribute, making it a name
+                     reference to another variable.  That  other  variable  is
+                     defined  by  the  value of _n_a_m_e.  All references, assign-
+                     ments, and attribute modifications to _n_a_m_e, except  those
+                     using  or changing the --nn attribute itself, are performed
+                     on the variable referenced by _n_a_m_e's value.  The  nameref
+                     attribute cannot be applied to array variables.
+              --rr     Make _n_a_m_es readonly.  These names cannot then be assigned
+                     values by subsequent assignment statements or unset.
+              --tt     Give each _n_a_m_e the _t_r_a_c_e attribute.  Traced functions in-
+                     herit  the DDEEBBUUGG and RREETTUURRNN traps from the calling shell.
+                     The trace attribute has no special meaning for variables.
+              --uu     When the variable is assigned  a  value,  all  lower-case
+                     characters  are  converted to upper-case.  The lower-case
+                     attribute is disabled.
+              --xx     Mark _n_a_m_es for export to subsequent commands via the  en-
+                     vironment.
+
+              Using  `+'  instead of `-' turns off the attribute instead, with
+              the exceptions that ++aa and ++AA may not be used to  destroy  array
+              variables  and  ++rr will not remove the readonly attribute.  When
+              used in a function, ddeeccllaarree and ttyyppeesseett make each _n_a_m_e local, as
+              with  the llooccaall command, unless the --gg option is supplied.  If a
+              variable name is followed by =_v_a_l_u_e, the value of  the  variable
+              is  set  to _v_a_l_u_e.  When using --aa or --AA and the compound assign-
+              ment syntax to create array variables, additional attributes  do
+              not  take effect until subsequent assignments.  The return value
+              is 0 unless an invalid option is encountered, an attempt is made
+              to define a function using ``-f foo=bar'', an attempt is made to

+              marked  so  that  SSIIGGHHUUPP is not sent to the job if the shell re-
+              ceives a SSIIGGHHUUPP.  If no _j_o_b_s_p_e_c is supplied, the --aa option means
+              to  remove or mark all jobs; the --rr option without a _j_o_b_s_p_e_c ar-
+              gument restricts operation to running jobs.  The return value is

+              the shell normally searches for builtins before  disk  commands.

+              were  ``enable  -f  _n_a_m_e  _n_a_m_e .  The return value is 0 unless a

+       eevvaall [_a_r_g ...]
+              The  _a_r_gs  are read and concatenated together into a single com-
+              mand.  This command is then read and executed by the shell,  and
+              its  exit status is returned as the value of eevvaall.  If there are
+              no _a_r_g_s, or only null arguments, eevvaall returns 0.
+
+       eexxeecc [--ccll] [--aa _n_a_m_e] [_c_o_m_m_a_n_d [_a_r_g_u_m_e_n_t_s]]
+              If _c_o_m_m_a_n_d is specified, it replaces the shell.  No new  process
+              is  created.  The _a_r_g_u_m_e_n_t_s become the arguments to _c_o_m_m_a_n_d.  If
+              the --ll option is supplied, the shell places a dash at the begin-
+              ning of the zeroth argument passed to _c_o_m_m_a_n_d.  This is what _l_o_-
+              _g_i_n(1) does.  The --cc option causes _c_o_m_m_a_n_d to be  executed  with
+              an  empty environment.  If --aa is supplied, the shell passes _n_a_m_e
+              as the zeroth argument to the executed command.  If _c_o_m_m_a_n_d can-
+              not  be executed for some reason, a non-interactive shell exits,
+              unless the eexxeeccffaaiill shell option is enabled.  In that  case,  it
+              returns  failure.   An  interactive shell returns failure if the
+              file cannot be executed.  A subshell  exits  unconditionally  if
+              eexxeecc  fails.  If _c_o_m_m_a_n_d is not specified, any redirections take
+              effect in the current shell, and the return  status  is  0.   If
+              there is a redirection error, the return status is 1.
+
+       eexxiitt [_n]
+              Cause  the  shell  to exit with a status of _n.  If _n is omitted,
+              the exit status is that of the last command executed.  A trap on
+              EEXXIITT is executed before the shell terminates.
+
+       eexxppoorrtt [--ffnn] [_n_a_m_e[=_w_o_r_d]] ...
+       eexxppoorrtt --pp
+              The  supplied _n_a_m_e_s are marked for automatic export to the envi-
+              ronment of subsequently executed commands.  If the --ff option  is
+              given,  the _n_a_m_e_s refer to functions.  If no _n_a_m_e_s are given, or
+              if the --pp option is supplied, a list of names  of  all  exported
+              variables  is printed.  The --nn option causes the export property
+              to be removed from each _n_a_m_e.  If a variable name is followed by
+              =_w_o_r_d, the value of the variable is set to _w_o_r_d.  eexxppoorrtt returns
+              an exit status of 0 unless an invalid option is encountered, one
+              of  the  _n_a_m_e_s is not a valid shell variable name, or --ff is sup-
+              plied with a _n_a_m_e that is not a function.
+
+       ffcc [--ee _e_n_a_m_e] [--llnnrr] [_f_i_r_s_t] [_l_a_s_t]
+       ffcc --ss [_p_a_t=_r_e_p] [_c_m_d]
+              The first form selects a range of commands from  _f_i_r_s_t  to  _l_a_s_t
+              from  the  history  list  and  displays or edits and re-executes
+              them.  _F_i_r_s_t and _l_a_s_t may be specified as a  string  (to  locate
+              the  last command beginning with that string) or as a number (an
+              index into the history list, where a negative number is used  as
+              an  offset  from  the  current command number).  When listing, a
+              _f_i_r_s_t or _l_a_s_t of 0 is equivalent to -1 and -0 is  equivalent  to
+              the  current  command  (usually  the ffcc command); otherwise 0 is
+              equivalent to -1 and -0 is invalid.  If _l_a_s_t is  not  specified,
+              it  is  set  to the current command for listing (so that ``fc -l
+              -10'' prints the last 10 commands) and to _f_i_r_s_t  otherwise.   If
+              _f_i_r_s_t  is  not  specified, it is set to the previous command for
+              editing and -16 for listing.
+
+              The --nn option suppresses the command numbers when listing.   The
+              --rr  option reverses the order of the commands.  If the --ll option
+              is given, the commands are listed on  standard  output.   Other-
+              wise,  the editor given by _e_n_a_m_e is invoked on a file containing
+              those commands.  If _e_n_a_m_e is not given, the value of the  FFCCEEDDIITT
+              variable  is used, and the value of EEDDIITTOORR if FFCCEEDDIITT is not set.
+              If neither variable is set, _v_i is used.  When  editing  is  com-
+              plete, the edited commands are echoed and executed.
+
+              In  the  second form, _c_o_m_m_a_n_d is re-executed after each instance
+              of _p_a_t is replaced by _r_e_p.  _C_o_m_m_a_n_d is interpreted the  same  as
+              _f_i_r_s_t  above.  A useful alias to use with this is ``r="fc -s"'',
+              so that typing ``r cc'' runs the  last  command  beginning  with
+              ``cc'' and typing ``r'' re-executes the last command.
+
+              If  the  first form is used, the return value is 0 unless an in-
+              valid option is encountered or _f_i_r_s_t  or  _l_a_s_t  specify  history
+              lines  out  of  range.  If the --ee option is supplied, the return
+              value is the value of the last command executed or failure if an
+              error occurs with the temporary file of commands.  If the second
+              form is used, the return status is that of the  command  re-exe-
+              cuted,  unless  _c_m_d  does  not  specify a valid history line, in
+              which case ffcc returns failure.
+
+       ffgg [_j_o_b_s_p_e_c]
+              Resume _j_o_b_s_p_e_c in the foreground, and make it the  current  job.
+              If _j_o_b_s_p_e_c is not present, the shell's notion of the _c_u_r_r_e_n_t _j_o_b
+              is used.  The return value is that of the  command  placed  into
+              the  foreground,  or failure if run when job control is disabled
+              or, when run with job control enabled, if _j_o_b_s_p_e_c does not spec-
+              ify  a  valid  job  or  _j_o_b_s_p_e_c specifies a job that was started
+              without job control.
+
+       ggeettooppttss _o_p_t_s_t_r_i_n_g _n_a_m_e [_a_r_g _._._.]
+              ggeettooppttss is used by shell procedures to parse positional  parame-
+              ters.   _o_p_t_s_t_r_i_n_g  contains  the  option characters to be recog-
+              nized; if a character is followed by a colon, the option is  ex-
+              pected to have an argument, which should be separated from it by
+              white space.  The colon and question mark characters may not  be
+              used  as  option  characters.   Each time it is invoked, ggeettooppttss
+              places the next option in the shell variable _n_a_m_e,  initializing
+              _n_a_m_e if it does not exist, and the index of the next argument to
+              be processed into the variable OOPPTTIINNDD.  OOPPTTIINNDD is initialized to
+              1 each time the shell or a shell script is invoked.  When an op-
+              tion requires an argument, ggeettooppttss places that argument into the
+              variable OOPPTTAARRGG.  The shell does not reset OOPPTTIINNDD automatically;
+              it must be manually reset  between  multiple  calls  to  ggeettooppttss
+              within  the  same shell invocation if a new set of parameters is
+              to be used.
+
+              When the end of options is encountered, ggeettooppttss exits with a re-
+              turn value greater than zero.  OOPPTTIINNDD is set to the index of the
+              first non-option argument, and _n_a_m_e is set to ?.
+
+              ggeettooppttss normally parses the positional parameters, but  if  more
+              arguments  are  supplied as _a_r_g values, ggeettooppttss parses those in-
+              stead.
+
+              ggeettooppttss can report errors in two ways.  If the  first  character
+              of  _o_p_t_s_t_r_i_n_g  is  a  colon, _s_i_l_e_n_t error reporting is used.  In
+              normal operation, diagnostic messages are printed  when  invalid
+              options  or  missing  option  arguments are encountered.  If the
+              variable OOPPTTEERRRR is set to 0, no  error  messages  will  be  dis-
+              played, even if the first character of _o_p_t_s_t_r_i_n_g is not a colon.
+
+              If an invalid option is seen, ggeettooppttss places ? into _n_a_m_e and, if
+              not silent, prints an  error  message  and  unsets  OOPPTTAARRGG.   If
+              ggeettooppttss  is  silent, the option character found is placed in OOPP--
+              TTAARRGG and no diagnostic message is printed.
+
+              If a required argument is not found, and ggeettooppttss is not  silent,
+              a  question  mark  (??) is placed in _n_a_m_e, OOPPTTAARRGG is unset, and a
+              diagnostic message is printed.  If ggeettooppttss  is  silent,  then  a
+              colon  (::)  is  placed  in  _n_a_m_e and OOPPTTAARRGG is set to the option
+              character found.
+
+              ggeettooppttss returns true if an option, specified or unspecified,  is
+              found.  It returns false if the end of options is encountered or
+              an error occurs.
+
+       hhaasshh [--llrr] [--pp _f_i_l_e_n_a_m_e] [--ddtt] [_n_a_m_e]
+              Each time hhaasshh is invoked, the full pathname of the command _n_a_m_e
+              is  determined  by searching the directories in $$PPAATTHH and remem-
+              bered.  Any previously-remembered pathname is discarded.  If the
+              --pp option is supplied, no path search is performed, and _f_i_l_e_n_a_m_e
+              is used as the full filename of  the  command.   The  --rr  option
+              causes the shell to forget all remembered locations.  The --dd op-
+              tion causes the shell to forget the remembered location of  each
+              _n_a_m_e.   If the --tt option is supplied, the full pathname to which
+              each _n_a_m_e corresponds is printed.  If  multiple  _n_a_m_e  arguments
+              are supplied with --tt, the _n_a_m_e is printed before the hashed full
+              pathname.  The --ll option causes output to be displayed in a for-
+              mat  that may be reused as input.  If no arguments are given, or
+              if only --ll is supplied, information about remembered commands is
+              printed.   The  return status is true unless a _n_a_m_e is not found
+              or an invalid option is supplied.
+

+              Display helpful information about builtin commands.  If  _p_a_t_t_e_r_n
+              is  specified, hheellpp gives detailed help on all commands matching
+              _p_a_t_t_e_r_n; otherwise help for all the builtins and  shell  control
+              structures is printed.

+              With no options, display the command history list with line num-
+              bers.  Lines listed with a ** have been modified.  An argument of
+              _n lists only the last _n lines.  If the shell variable  HHIISSTTTTIIMMEE--
+              FFOORRMMAATT  is  set  and not null, it is used as a format string for
+              _s_t_r_f_t_i_m_e(3) to display the time stamp associated with each  dis-
+              played  history  entry.  No intervening blank is printed between
+              the formatted time stamp and the history line.  If  _f_i_l_e_n_a_m_e  is
+              supplied,  it  is  used as the name of the history file; if not,
+              the value of HHIISSTTFFIILLEE is used.  Options, if supplied,  have  the
+              following meanings:
+              --cc     Clear the history list by deleting all the entries.
+              --dd _o_f_f_s_e_t
+                     Delete  the  history entry at position _o_f_f_s_e_t.  If _o_f_f_s_e_t
+                     is negative, it is interpreted as relative to one greater
+                     than the last history position, so negative indices count
+                     back from the end of the history,  and  an  index  of  -1
+                     refers to the current hhiissttoorryy --dd command.
+              --dd _s_t_a_r_t-_e_n_d
+                     Delete  the  range  of  history entries between positions
+                     _s_t_a_r_t and _e_n_d, inclusive.  Positive and  negative  values
+                     for _s_t_a_r_t and _e_n_d are interpreted as described above.
+              --aa     Append  the  ``new''  history  lines to the history file.
+                     These are history lines entered since  the  beginning  of
+                     the current bbaasshh session, but not already appended to the
+                     history file.
+              --nn     Read the history lines not already read from the  history
+                     file  into the current history list.  These are lines ap-
+                     pended to the history file since  the  beginning  of  the
+                     current bbaasshh session.
+              --rr     Read  the contents of the history file and append them to
+                     the current history list.
+              --ww     Write the current history list to the history file, over-
+                     writing the history file's contents.
+              --pp     Perform  history  substitution  on the following _a_r_g_s and
+                     display the result on  the  standard  output.   Does  not
+                     store  the results in the history list.  Each _a_r_g must be
+                     quoted to disable normal history expansion.
+              --ss     Store the _a_r_g_s in the history list  as  a  single  entry.
+                     The  last  command  in the history list is removed before
+                     the _a_r_g_s are added.
+
+              If the HHIISSTTTTIIMMEEFFOORRMMAATT variable is set, the time  stamp  informa-
+              tion  associated  with each history entry is written to the his-
+              tory file, marked with the history comment character.  When  the
+              history  file  is read, lines beginning with the history comment
+              character followed immediately by a  digit  are  interpreted  as
+              timestamps for the following history entry.  The return value is
+              0 unless an invalid option is encountered, an error occurs while
+              reading  or writing the history file, an invalid _o_f_f_s_e_t or range
+              is supplied as an argument to --dd, or the history expansion  sup-
+              plied as an argument to --pp fails.

+              named  by  _p_i_d or _j_o_b_s_p_e_c.  _s_i_g_s_p_e_c is either a case-insensitive

+              a  signal  number; _s_i_g_n_u_m is a signal number.  If _s_i_g_s_p_e_c is not
+              present, then SSIIGGTTEERRMM is assumed.  An argument of --ll  lists  the
+              signal  names.   If any arguments are supplied when --ll is given,
+              the names of the signals  corresponding  to  the  arguments  are

+              --ll is a number specifying either a signal  number  or  the  exit
+              status  of  a  process terminated by a signal.  The --LL option is
+              equivalent to --ll.  kkiillll returns true if at least one signal  was

+       llooccaall [_o_p_t_i_o_n] [_n_a_m_e[=_v_a_l_u_e] ... | - ]
+              For each argument, a local variable named _n_a_m_e is  created,  and
+              assigned  _v_a_l_u_e.   The _o_p_t_i_o_n can be any of the options accepted
+              by ddeeccllaarree.  When llooccaall is used within a function, it causes the
+              variable  _n_a_m_e  to have a visible scope restricted to that func-
+              tion and its children.  If _n_a_m_e is -, the set of  shell  options
+              is  made  local to the function in which llooccaall is invoked: shell
+              options changed using the sseett builtin inside  the  function  are
+              restored  to  their  original  values when the function returns.
+              The restore is effected as if a series of sseett commands were exe-
+              cuted  to restore the values that were in place before the func-
+              tion.  With no operands, llooccaall writes a list of local  variables
+              to  the  standard  output.  It is an error to use llooccaall when not

+              supplied, have the following meanings:
+              --dd     The  first  character  of _d_e_l_i_m is used to terminate each
+                     input line, rather than newline.  If _d_e_l_i_m is  the  empty

+                     --cc option specifies _q_u_a_n_t_u_m.
+              --cc     Specify  the  number  of  lines read between each call to
+                     _c_a_l_l_b_a_c_k.
+
+              If --CC is specified without --cc,  the  default  quantum  is  5000.
+              When _c_a_l_l_b_a_c_k is evaluated, it is supplied the index of the next

+
+              If not supplied with an explicit origin, mmaappffiillee will clear  _a_r_-

+       ppooppdd [-nn] [+_n] [-_n]
+              Removes entries from the directory stack.  The elements are num-
+              bered from 0 starting at the first  directory  listed  by  ddiirrss.
+              With  no  arguments,  ppooppdd  removes  the  top directory from the
+              stack, and changes to the new top directory.  Arguments, if sup-
+              plied, have the following meanings:
+              --nn     Suppresses  the  normal change of directory when removing
+                     directories from the stack, so that only the stack is ma-
+                     nipulated.
+              ++_n     Removes  the _nth entry counting from the left of the list
+                     shown by ddiirrss, starting with zero, from the  stack.   For
+                     example:  ``popd +0'' removes the first directory, ``popd
+                     +1'' the second.
+              --_n     Removes the _nth entry counting from the right of the list
+                     shown  by  ddiirrss, starting with zero.  For example: ``popd
+                     -0'' removes the last directory, ``popd -1'' the next  to
+                     last.
+
+              If  the  top element of the directory stack is modified, and the
+              _-_n option was not supplied, ppooppdd uses the ccdd builtin  to  change
+              to the directory at the top of the stack.  If the ccdd fails, ppooppdd
+              returns a non-zero value.
+
+              Otherwise, ppooppdd returns false if an invalid  option  is  encoun-
+              tered, the directory stack is empty, or a non-existent directory
+              stack entry is specified.
+
+              If the ppooppdd command is successful, bash runs ddiirrss  to  show  the
+              final  contents of the directory stack, and the return status is
+              0.
+
+       pprriinnttff [--vv _v_a_r] _f_o_r_m_a_t [_a_r_g_u_m_e_n_t_s]
+              Write the formatted _a_r_g_u_m_e_n_t_s to the standard output  under  the
+              control  of  the  _f_o_r_m_a_t.  The --vv option causes the output to be
+              assigned to the variable _v_a_r rather than being  printed  to  the
+              standard output.
+
+              The  _f_o_r_m_a_t  is a character string which contains three types of
+              objects: plain characters, which are simply copied  to  standard
+              output,  character  escape  sequences,  which  are converted and
+              copied to the standard output, and format  specifications,  each
+              of  which  causes  printing of the next successive _a_r_g_u_m_e_n_t.  In
+              addition to the standard _p_r_i_n_t_f(1) format specifications, pprriinnttff
+              interprets the following extensions:
+              %%bb     causes pprriinnttff to expand backslash escape sequences in the
+                     corresponding _a_r_g_u_m_e_n_t in the same way as eecchhoo --ee.
+              %%qq     causes pprriinnttff to output the corresponding _a_r_g_u_m_e_n_t  in  a
+                     format that can be reused as shell input.
+              %%QQ     like  %%qq, but applies any supplied precision to the _a_r_g_u_-
+                     _m_e_n_t before quoting it.
+              %%((_d_a_t_e_f_m_t))TT
+                     causes pprriinnttff to output the  date-time  string  resulting
+                     from  using  _d_a_t_e_f_m_t  as a format string for _s_t_r_f_t_i_m_e(3).
+                     The corresponding _a_r_g_u_m_e_n_t is an integer representing the
+                     number  of seconds since the epoch.  Two special argument
+                     values may be used: -1 represents the current  time,  and
+                     -2  represents the time the shell was invoked.  If no ar-
+                     gument is specified, conversion behaves as if -1 had been
+                     given.   This  is an exception to the usual pprriinnttff behav-
+                     ior.
+
+              The %b, %q, and %T directives all use the field width and preci-
+              sion arguments from the format specification and write that many
+              bytes from (or use that wide a field for) the expanded argument,
+              which usually contains more characters than the original.
+
+              Arguments  to non-string format specifiers are treated as C con-
+              stants, except that a leading plus or minus sign is allowed, and
+              if  the leading character is a single or double quote, the value
+              is the ASCII value of the following character.
+
+              The _f_o_r_m_a_t is reused as necessary to consume all  of  the  _a_r_g_u_-
+              _m_e_n_t_s.  If the _f_o_r_m_a_t requires more _a_r_g_u_m_e_n_t_s than are supplied,
+              the extra format specifications behave as if  a  zero  value  or
+              null  string,  as  appropriate,  had  been supplied.  The return
+              value is zero on success, non-zero on failure.
+
+       ppuusshhdd [--nn] [+_n] [-_n]
+       ppuusshhdd [--nn] [_d_i_r]
+              Adds a directory to the top of the directory stack,  or  rotates
+              the  stack,  making the new top of the stack the current working
+              directory.  With no arguments, ppuusshhdd exchanges the top two  ele-
+              ments  of the directory stack.  Arguments, if supplied, have the
+              following meanings:
+              --nn     Suppresses the normal change of directory  when  rotating
+                     or  adding  directories  to  the  stack, so that only the
+                     stack is manipulated.
+              ++_n     Rotates the stack so that  the  _nth  directory  (counting
+                     from  the  left  of the list shown by ddiirrss, starting with
+                     zero) is at the top.
+              --_n     Rotates the stack so that  the  _nth  directory  (counting
+                     from  the  right of the list shown by ddiirrss, starting with
+                     zero) is at the top.
+              _d_i_r    Adds _d_i_r to the directory stack at the top
+
+              After the stack has been modified, if the --nn option was not sup-
+              plied,  ppuusshhdd  uses the ccdd builtin to change to the directory at
+              the top of the stack.  If the ccdd fails, ppuusshhdd returns a non-zero
+              value.
+
+              Otherwise,  if no arguments are supplied, ppuusshhdd returns 0 unless
+              the directory stack  is  empty.   When  rotating  the  directory
+              stack,  ppuusshhdd returns 0 unless the directory stack is empty or a
+              non-existent directory stack element is specified.
+
+              If the ppuusshhdd command is successful, bash runs ddiirrss to  show  the
+              final contents of the directory stack.

+              is supplied or the --oo pphhyyssiiccaall option to the sseett builtin command
+              is enabled.  If the --LL option is used, the pathname printed  may

+              ond _n_a_m_e, and so on.  If there are more words  than  names,  the
+              remaining words and their intervening delimiters are assigned to
+              the last _n_a_m_e.  If there are fewer words  read  from  the  input
+              stream  than  names, the remaining names are assigned empty val-
+              ues.  The characters in IIFFSS are used  to  split  the  line  into
+              words  using  the  same  rules the shell uses for expansion (de-
+              scribed above under WWoorrdd SSpplliittttiinngg).   The  backslash  character
+              (\\) may be used to remove any special meaning for the next char-
+              acter read and for line  continuation.   Options,  if  supplied,
+              have the following meanings:
+              --aa _a_n_a_m_e
+                     The words are assigned to sequential indices of the array
+                     variable _a_n_a_m_e, starting at 0.  _a_n_a_m_e is unset before any
+                     new  values  are  assigned.  Other _n_a_m_e arguments are ig-
+                     nored.
+              --dd _d_e_l_i_m
+                     The first character of _d_e_l_i_m is used to terminate the in-
+                     put  line,  rather  than  newline.  If _d_e_l_i_m is the empty
+                     string, rreeaadd will terminate a line when it  reads  a  NUL
+                     character.

+                     EOF  is encountered or rreeaadd times out.  Delimiter charac-
+                     ters encountered in the input are not  treated  specially
+                     and  do  not cause rreeaadd to return until _n_c_h_a_r_s characters
+                     are read.  The result is not split on the  characters  in
+                     IIFFSS;  the intent is that the variable is assigned exactly
+                     the characters read (with the exception of backslash; see
+                     the --rr option below).
+              --pp _p_r_o_m_p_t
+                     Display _p_r_o_m_p_t on standard error, without a trailing new-
+                     line, before attempting to read any input.  The prompt is
+                     displayed only if input is coming from a terminal.
+              --rr     Backslash does not act as an escape character.  The back-
+                     slash is considered to be part of the line.  In  particu-
+                     lar,  a  backslash-newline pair may not then be used as a
+                     line continuation.
+              --ss     Silent mode.  If input is coming from a terminal, charac-
+                     ters are not echoed.
+              --tt _t_i_m_e_o_u_t
+                     Cause  rreeaadd  to time out and return failure if a complete
+                     line of input (or a specified number  of  characters)  is
+                     not  read within _t_i_m_e_o_u_t seconds.  _t_i_m_e_o_u_t may be a deci-
+                     mal number with a fractional portion following the  deci-
+                     mal  point.   This  option  is  only effective if rreeaadd is
+                     reading input from a terminal,  pipe,  or  other  special
+                     file;  it  has no effect when reading from regular files.
+                     If rreeaadd times out, rreeaadd saves any partial input read into
+                     the  specified  variable _n_a_m_e.  If _t_i_m_e_o_u_t is 0, rreeaadd re-
+                     turns immediately, without trying to read any data.   The
+                     exit  status  is 0 if input is available on the specified
+                     file descriptor, or the read will  return  EOF,  non-zero
+                     otherwise.   The  exit  status is greater than 128 if the
+                     timeout is exceeded.
+              --uu _f_d  Read input from file descriptor _f_d.
+
+              If no _n_a_m_e_s are supplied, the line read, without the ending  de-
+              limiter  but  otherwise  unmodified, is assigned to the variable
+              RREEPPLLYY.  The exit status is zero, unless end-of-file  is  encoun-
+              tered,  rreeaadd times out (in which case the status is greater than
+              128), a variable assignment error (such as assigning to a  read-
+              only variable) occurs, or an invalid file descriptor is supplied
+              as the argument to --uu.
+
+       rreeaaddoonnllyy [--aaAAff] [--pp] [_n_a_m_e[=_w_o_r_d] ...]
+              The given _n_a_m_e_s are marked readonly; the values of  these  _n_a_m_e_s
+              may  not  be changed by subsequent assignment.  If the --ff option
+              is supplied, the functions corresponding to  the  _n_a_m_e_s  are  so
+              marked.   The  --aa  option restricts the variables to indexed ar-
+              rays; the --AA option restricts the variables to  associative  ar-
+              rays.  If both options are supplied, --AA takes precedence.  If no
+              _n_a_m_e arguments are given, or if the --pp  option  is  supplied,  a
+              list of all readonly names is printed.  The other options may be
+              used to restrict the output to a subset of the set  of  readonly
+              names.   The --pp option causes output to be displayed in a format
+              that may be reused as input.  If a variable name is followed  by
+              =_w_o_r_d,  the  value  of  the variable is set to _w_o_r_d.  The return
+              status is 0 unless an invalid option is encountered, one of  the
+              _n_a_m_e_s is not a valid shell variable name, or --ff is supplied with
+              a _n_a_m_e that is not a function.
+
+       rreettuurrnn [_n]
+              Causes a function to stop executing and return the value  speci-
+              fied  by _n to its caller.  If _n is omitted, the return status is
+              that of the last command executed in the function body.  If  rree--
+              ttuurrnn is executed by a trap handler, the last command used to de-
+              termine the status is the last command executed before the  trap
+              handler.   If  rreettuurrnn  is executed during a DDEEBBUUGG trap, the last
+              command used to determine the status is the  last  command  exe-
+              cuted  by the trap handler before rreettuurrnn was invoked.  If rreettuurrnn
+              is used outside a function, but during execution of a script  by
+              the  ..   (ssoouurrccee) command, it causes the shell to stop executing
+              that script and return either _n or the exit status of  the  last
+              command  executed  within  the  script as the exit status of the
+              script.  If _n is supplied, the return value is its least signif-
+              icant  8  bits.  The return status is non-zero if rreettuurrnn is sup-
+              plied a non-numeric argument, or is used outside a function  and
+              not  during  execution  of a script by .. or ssoouurrccee.  Any command
+              associated with the RREETTUURRNN trap is executed before execution re-
+              sumes after the function or script.

+                      compound command other than a subshell  returns  a  non-
+                      zero  status because a command failed while --ee was being
+                      ignored, the shell does not exit.  A  trap  on  EERRRR,  if
+                      set,  is  executed  before the shell exits.  This option
+                      applies to the shell environment and each subshell envi-
+                      ronment  separately  (see  CCOOMMMMAANNDD EEXXEECCUUTTIIOONN EENNVVIIRROONNMMEENNTT

+
+                      If  a  compound  command or shell function executes in a

+                      scripted  with  "@"  or "*", as an error when performing
+                      parameter expansion.  If expansion is  attempted  on  an
+                      unset  variable  or parameter, the shell prints an error
+                      message, and, if not interactive, exits with a  non-zero
+                      status.

+                      and its expanded arguments or associated word list.
+              --BB      The shell performs brace expansion (see BBrraaccee  EExxppaannssiioonn
+                      above).  This is on by default.
+              --CC      If  set,  bbaasshh  does not overwrite an existing file with
+                      the >>, >>&&, and <<>> redirection operators.   This  may  be
+                      overridden when creating output files by using the redi-
+                      rection operator >>|| instead of >>.
+              --EE      If set, any trap on EERRRR is inherited by shell functions,
+                      command  substitutions,  and commands executed in a sub-
+                      shell environment.  The EERRRR trap is normally not  inher-
+                      ited in such cases.
+              --HH      Enable !!  style history substitution.  This option is on
+                      by default when the shell is interactive.
+              --PP      If set, the shell does not resolve symbolic  links  when
+                      executing  commands  such  as ccdd that change the current
+                      working  directory.   It  uses  the  physical  directory
+                      structure instead.  By default, bbaasshh follows the logical
+                      chain of  directories  when  performing  commands  which
+                      change the current directory.
+              --TT      If  set,  any traps on DDEEBBUUGG and RREETTUURRNN are inherited by
+                      shell functions, command substitutions, and commands ex-
+                      ecuted  in a subshell environment.  The DDEEBBUUGG and RREETTUURRNN
+                      traps are normally not inherited in such cases.
+              ----      If no arguments follow this option, then the  positional
+                      parameters are unset.  Otherwise, the positional parame-
+                      ters are set to the _a_r_gs, even if  some  of  them  begin
+                      with a --.
+              --       Signal  the  end of options, cause all remaining _a_r_gs to
+                      be assigned to the positional parameters.  The --xx and --vv
+                      options are turned off.  If there are no _a_r_gs, the posi-
+                      tional parameters remain unchanged.
+
+              The options are off by default unless otherwise noted.  Using  +
+              rather  than  -  causes these options to be turned off.  The op-
+              tions can also be specified as arguments to an invocation of the
+              shell.   The current set of options may be found in $$--.  The re-
+              turn status is always true unless an invalid option  is  encoun-
+              tered.

+              Parameters represented by the numbers $$## down to $$##-_n+1 are  un-
+              set.   _n must be a non-negative number less than or equal to $$##.
+              If _n is 0, no parameters are changed.  If _n is not given, it  is
+              assumed to be 1.  If _n is greater than $$##, the positional param-
+              eters are not changed.  The return status is greater  than  zero
+              if _n is greater than $$## or less than zero; otherwise 0.
+
+       sshhoopptt [--ppqqssuu] [--oo] [_o_p_t_n_a_m_e ...]
+              Toggle  the values of settings controlling optional shell behav-
+              ior.  The settings can be either those listed below, or, if  the
+              --oo option is used, those available with the --oo option to the sseett
+              builtin command.  With no options, or with the --pp option, a list
+              of  all  settable  options  is  displayed, with an indication of
+              whether or not each is set; if _o_p_t_n_a_m_e_s are supplied, the output
+              is  restricted to those options.  The --pp option causes output to
+              be displayed in a form that may be reused as input.   Other  op-
+              tions have the following meanings:
+              --ss     Enable (set) each _o_p_t_n_a_m_e.
+              --uu     Disable (unset) each _o_p_t_n_a_m_e.
+              --qq     Suppresses  normal output (quiet mode); the return status
+                     indicates whether the _o_p_t_n_a_m_e is set or unset.  If multi-
+                     ple  _o_p_t_n_a_m_e arguments are given with --qq, the return sta-
+                     tus is zero if all _o_p_t_n_a_m_e_s are enabled; non-zero  other-
+                     wise.
+              --oo     Restricts  the  values of _o_p_t_n_a_m_e to be those defined for
+                     the --oo option to the sseett builtin.
+
+              If either --ss or --uu is used  with  no  _o_p_t_n_a_m_e  arguments,  sshhoopptt
+              shows  only  those options which are set or unset, respectively.
+              Unless otherwise noted, the sshhoopptt options are  disabled  (unset)
+              by default.
+
+              The  return  status when listing options is zero if all _o_p_t_n_a_m_e_s
+              are enabled, non-zero otherwise.  When setting or unsetting  op-
+              tions,  the  return  status  is  zero unless an _o_p_t_n_a_m_e is not a
+              valid shell option.
+
+              The list of sshhoopptt options is:
+
+              aassssoocc__eexxppaanndd__oonnccee
+                      If set, the shell suppresses multiple evaluation of  as-
+                      sociative  array subscripts during arithmetic expression
+                      evaluation, while executing builtins  that  can  perform
+                      variable  assignments, and while executing builtins that
+                      perform array dereferencing.
+              aauuttooccdd  If set, a command name that is the name of  a  directory
+                      is  executed  as  if it were the argument to the ccdd com-
+                      mand.  This option is only used by interactive shells.
+              ccddaabbllee__vvaarrss
+                      If set, an argument to the ccdd builtin  command  that  is
+                      not  a directory is assumed to be the name of a variable
+                      whose value is the directory to change to.
+              ccddssppeellll If set, minor errors in the spelling of a directory com-
+                      ponent  in  a  ccdd command will be corrected.  The errors
+                      checked for are transposed characters, a missing charac-
+                      ter,  and  one  character  too many.  If a correction is
+                      found, the corrected filename is printed, and  the  com-
+                      mand  proceeds.  This option is only used by interactive
+                      shells.
+              cchheecckkhhaasshh
+                      If set, bbaasshh checks that a command found in the hash ta-
+                      ble  exists  before  trying  to execute it.  If a hashed
+                      command no longer exists, a normal path search  is  per-
+                      formed.
+              cchheecckkjjoobbss
+                      If set, bbaasshh lists the status of any stopped and running
+                      jobs before exiting an interactive shell.  If  any  jobs
+                      are running, this causes the exit to be deferred until a
+                      second exit is attempted without an intervening  command
+                      (see JJOOBB CCOONNTTRROOLL above).  The shell always postpones ex-
+                      iting if any jobs are stopped.
+              cchheecckkwwiinnssiizzee
+                      If set, bbaasshh checks the window size after each  external
+                      (non-builtin)  command  and,  if  necessary, updates the
+                      values of LLIINNEESS and CCOOLLUUMMNNSS.  This option is enabled  by
+                      default.
+              ccmmddhhiisstt If  set,  bbaasshh attempts to save all lines of a multiple-
+                      line command in the same  history  entry.   This  allows
+                      easy  re-editing of multi-line commands.  This option is
+                      enabled by default, but only has an  effect  if  command
+                      history is enabled, as described above under HHIISSTTOORRYY.

+
+              ccoommpplleettee__ffuullllqquuoottee
+                      If set, bbaasshh quotes all shell  metacharacters  in  file-
+                      names  and  directory  names when performing completion.
+                      If not set, bbaasshh removes metacharacters such as the dol-
+                      lar  sign from the set of characters that will be quoted
+                      in completed filenames when these metacharacters  appear
+                      in  shell  variable references in words to be completed.
+                      This means that dollar signs in variable names that  ex-
+                      pand  to  directories  will  not be quoted; however, any
+                      dollar signs appearing in filenames will not be  quoted,
+                      either.   This  is  active only when bash is using back-
+                      slashes to quote completed filenames.  This variable  is
+                      set  by  default,  which is the default bash behavior in
+                      versions through 4.2.
+
+              ddiirreexxppaanndd
+                      If set, bbaasshh replaces directory names with  the  results
+                      of  word  expansion when performing filename completion.
+                      This changes the contents of the readline  editing  buf-
+                      fer.   If  not  set,  bbaasshh attempts to preserve what the
+                      user typed.
+
+              ddiirrssppeellll
+                      If set, bbaasshh attempts spelling correction  on  directory
+                      names  during word completion if the directory name ini-
+                      tially supplied does not exist.
+
+              ddoottgglloobb If set, bbaasshh includes filenames beginning with a `.'  in
+                      the  results of pathname expansion.  The filenames ````..''''
+                      and ````....''''  must always be matched explicitly,  even  if
+                      ddoottgglloobb is set.
+
+              eexxeeccffaaiill
+                      If set, a non-interactive shell will not exit if it can-
+                      not execute the file specified as  an  argument  to  the
+                      eexxeecc  builtin  command.   An  interactive shell does not
+                      exit if eexxeecc fails.
+
+              eexxppaanndd__aalliiaasseess
+                      If set, aliases are expanded as  described  above  under
+                      AALLIIAASSEESS.  This option is enabled by default for interac-
+                      tive shells.
+
+              eexxttddeebbuugg
+                      If set at shell invocation, or in a shell startup  file,
+                      arrange to execute the debugger profile before the shell
+                      starts, identical to the ----ddeebbuuggggeerr option.  If set  af-
+                      ter  invocation,  behavior intended for use by debuggers
+                      is enabled:
+
+                      11..     The --FF option to the ddeeccllaarree builtin displays the
+                             source file name and line number corresponding to
+                             each function name supplied as an argument.
+
+                      22..     If the command run by the DDEEBBUUGG  trap  returns  a
+                             non-zero  value,  the next command is skipped and
+                             not executed.
+
+                      33..     If the command run by the DDEEBBUUGG  trap  returns  a
+                             value  of 2, and the shell is executing in a sub-
+                             routine (a shell function or a shell script  exe-
+                             cuted  by  the  ..  or ssoouurrccee builtins), the shell
+                             simulates a call to rreettuurrnn.

+
+              eexxttqquuoottee
+                      If set, $$'_s_t_r_i_n_g' and  $$"_s_t_r_i_n_g"  quoting  is  performed

+
+              ffaaiillgglloobb
+                      If set, patterns which fail to  match  filenames  during

+                      variable cause words to be ignored when performing  word
+                      completion even if the ignored words are the only possi-

+              Return a status of 0 (true) or 1 (false) depending on the evalu-
+              ation of the conditional expression _e_x_p_r.  Each operator and op-
+              erand must be a separate argument.  Expressions are composed  of
+              the  primaries  described  above  under CCOONNDDIITTIIOONNAALL EEXXPPRREESSSSIIOONNSS.

+
+              0 arguments
+                     The expression is false.
+              1 argument
+                     The expression is true if and only if the argument is not

+              2 arguments
+                     If the first argument is !!, the expression is true if and
+                     only if the second argument is null.  If the first  argu-
+                     ment  is  one  of  the unary conditional operators listed
+                     above under CCOONNDDIITTIIOONNAALL EEXXPPRREESSSSIIOONNSS,  the  expression  is
+                     true if the unary test is true.  If the first argument is
+                     not a valid unary conditional operator, the expression is
+                     false.
+              3 arguments
+                     The following conditions are applied in the order listed.
+                     If the second argument is one of the  binary  conditional
+                     operators listed above under CCOONNDDIITTIIOONNAALL EEXXPPRREESSSSIIOONNSS, the
+                     result of the expression is the result of the binary test
+                     using  the first and third arguments as operands.  The --aa
+                     and --oo operators are  considered  binary  operators  when
+                     there  are  three arguments.  If the first argument is !!,
+                     the value is the negation of the two-argument test  using
+                     the second and third arguments.  If the first argument is
+                     exactly (( and the third argument is exactly )), the result
+                     is  the one-argument test of the second argument.  Other-
+                     wise, the expression is false.
+              4 arguments
+                     The following conditions are applied in the order listed.
+                     If the first argument is !!, the result is the negation of
+                     the three-argument expression composed of  the  remaining
+                     arguments.   the  two-argument  test using the second and

+                     the  fourth argument is exactly )), the result is the two-
+                     argument test of the second and third arguments.   Other-
+                     wise, the expression is parsed and evaluated according to

+       ttrraapp [--llpp] [[_a_r_g] _s_i_g_s_p_e_c ...]
+              The  command  _a_r_g  is to be read and executed when the shell re-
+              ceives signal(s) _s_i_g_s_p_e_c.  If _a_r_g is absent (and there is a sin-
+              gle  _s_i_g_s_p_e_c) or --, each specified signal is reset to its origi-
+              nal disposition (the value it had upon entrance to  the  shell).
+              If  _a_r_g  is the null string the signal specified by each _s_i_g_s_p_e_c
+              is ignored by the shell and by the commands it invokes.  If  _a_r_g
+              is  not present and --pp has been supplied, then the trap commands
+              associated with each _s_i_g_s_p_e_c are displayed.  If no arguments are
+              supplied  or  if  only --pp is given, ttrraapp prints the list of com-
+              mands associated with each signal.  The  --ll  option  causes  the
+              shell  to  print  a list of signal names and their corresponding
+              numbers.  Each _s_i_g_s_p_e_c is either a signal name defined in  <_s_i_g_-
+              _n_a_l_._h>,  or  a signal number.  Signal names are case insensitive
+              and the SSIIGG prefix is optional.
+
+              If a _s_i_g_s_p_e_c is EEXXIITT (0) the command _a_r_g  is  executed  on  exit
+              from  the shell.  If a _s_i_g_s_p_e_c is DDEEBBUUGG, the command _a_r_g is exe-
+              cuted before every _s_i_m_p_l_e _c_o_m_m_a_n_d, _f_o_r  command,  _c_a_s_e  command,
+              _s_e_l_e_c_t  command,  every  arithmetic  _f_o_r command, and before the
+              first command executes in a shell function  (see  SSHHEELLLL  GGRRAAMMMMAARR
+              above).   Refer to the description of the eexxttddeebbuugg option to the
+              sshhoopptt builtin for details of its effect on the DDEEBBUUGG trap.  If a
+              _s_i_g_s_p_e_c is RREETTUURRNN, the command _a_r_g is executed each time a shell
+              function or a script executed with the .. or ssoouurrccee builtins fin-
+              ishes executing.
+
+              If  a  _s_i_g_s_p_e_c  is  EERRRR,  the command _a_r_g is executed whenever a
+              pipeline (which may consist of a single simple command), a list,
+              or a compound command returns a non-zero exit status, subject to
+              the following conditions.  The EERRRR trap is not executed  if  the
+              failed command is part of the command list immediately following
+              a wwhhiillee or uunnttiill keyword, part of the test in an  _i_f  statement,
+              part of a command executed in a &&&& or |||| list except the command
+              following the final &&&& or ||||, any command in a pipeline but  the
+              last,  or  if the command's return value is being inverted using
+              !!.  These are the same conditions obeyed by the eerrrreexxiitt (--ee) op-
+              tion.
+
+              Signals ignored upon entry to the shell cannot be trapped or re-
+              set.  Trapped signals that are not being ignored  are  reset  to
+              their original values in a subshell or subshell environment when
+              one is created.  The return status is false if  any  _s_i_g_s_p_e_c  is
+              invalid; otherwise ttrraapp returns true.
+
+       ttyyppee [--aaffttppPP] _n_a_m_e [_n_a_m_e ...]
+              With  no options, indicate how each _n_a_m_e would be interpreted if
+              used as a command name.  If the --tt option is used, ttyyppee prints a
+              string  which  is  one  of _a_l_i_a_s, _k_e_y_w_o_r_d, _f_u_n_c_t_i_o_n, _b_u_i_l_t_i_n, or
+              _f_i_l_e if  _n_a_m_e  is  an  alias,  shell  reserved  word,  function,
+              builtin,  or disk file, respectively.  If the _n_a_m_e is not found,
+              then nothing is printed, and an exit  status  of  false  is  re-
+              turned.   If the --pp option is used, ttyyppee either returns the name
+              of the disk file that would be executed if _n_a_m_e  were  specified
+              as  a command name, or nothing if ``type -t name'' would not re-
+              turn _f_i_l_e.  The --PP option forces a PPAATTHH search  for  each  _n_a_m_e,
+              even if ``type -t name'' would not return _f_i_l_e.  If a command is
+              hashed, --pp and --PP print the hashed value, which is not necessar-
+              ily  the  file  that appears first in PPAATTHH.  If the --aa option is
+              used, ttyyppee prints all of the places that contain  an  executable
+              named _n_a_m_e.  This includes aliases and functions, if and only if
+              the --pp option is not also used.  The table of hashed commands is
+              not  consulted  when  using  --aa.  The --ff option suppresses shell
+              function lookup, as with the ccoommmmaanndd builtin.  ttyyppee returns true
+              if all of the arguments are found, false if any are not found.

+              Provides  control  over the resources available to the shell and
+              to processes started by it, on systems that allow such  control.
+              The --HH and --SS options specify that the hard or soft limit is set
+              for the given resource.  A hard limit cannot be increased  by  a
+              non-root  user  once it is set; a soft limit may be increased up
+              to the value of the hard limit.  If neither --HH nor --SS is  speci-
+              fied, both the soft and hard limits are set.  The value of _l_i_m_i_t
+              can be a number in the unit specified for the resource or one of
+              the special values hhaarrdd, ssoofftt, or uunnlliimmiitteedd, which stand for the
+              current hard limit, the current soft limit, and  no  limit,  re-
+              spectively.   If _l_i_m_i_t is omitted, the current value of the soft
+              limit of the resource is printed, unless the --HH option is given.
+              When  more  than  one  resource is specified, the limit name and
+              unit, if appropriate, are printed before the value.   Other  op-
+              tions are interpreted as follows:

+
+              If  _l_i_m_i_t  is given, and the --aa option is not used, _l_i_m_i_t is the
+              new value of the specified resource.  If  no  option  is  given,
+              then  --ff is assumed.  Values are in 1024-byte increments, except

+              --ff,  which  are  in 512-byte increments.  The return status is 0
+              unless an invalid option or argument is supplied,  or  an  error

+
+       uummaasskk [--pp] [--SS] [_m_o_d_e]
+              The user file-creation mask is set to _m_o_d_e.  If _m_o_d_e begins with
+              a digit, it is interpreted as an octal number; otherwise  it  is
+              interpreted  as a symbolic mode mask similar to that accepted by
+              _c_h_m_o_d(1).  If _m_o_d_e is omitted, the current value of the mask  is
+              printed.   The  --SS  option causes the mask to be printed in sym-
+              bolic form; the default output is an octal number.   If  the  --pp
+              option is supplied, and _m_o_d_e is omitted, the output is in a form
+              that may be reused as input.  The return status is 0 if the mode
+              was  successfully  changed  or if no _m_o_d_e argument was supplied,

+

+              For each _n_a_m_e, remove the corresponding  variable  or  function.
+              If the --vv option is given, each _n_a_m_e refers to a shell variable,
+              and that variable is removed.  Read-only variables  may  not  be
+              unset.   If  --ff  is specified, each _n_a_m_e refers to a shell func-
+              tion, and the function definition is removed.  If the --nn  option
+              is  supplied, and _n_a_m_e is a variable with the _n_a_m_e_r_e_f attribute,
+              _n_a_m_e will be unset rather than the variable it  references.   --nn
+              has  no  effect if the --ff option is supplied.  If no options are
+              supplied, each _n_a_m_e refers to a variable; if there is  no  vari-
+              able  by that name, a function with that name, if any, is unset.

+
+       wwaaiitt [--ffnn] [--pp _v_a_r_n_a_m_e] [_i_d _._._.]
+              Wait for each specified child process and return its termination
+              status.  Each _i_d may be a process ID or a job specification;  if
+              a  job  spec  is given, all processes in that job's pipeline are
+              waited for.  If _i_d is not given,  wwaaiitt  waits  for  all  running
+              background  jobs  and the last-executed process substitution, if
+              its process id is the same as $$!!, and the return status is zero.
+              If  the  --nn option is supplied, wwaaiitt waits for a single job from
+              the list of _i_ds or, if no _i_ds are supplied, any job, to complete
+              and  returns its exit status.  If none of the supplied arguments
+              is a child of the shell, or if no arguments are supplied and the
+              shell  has no unwaited-for children, the exit status is 127.  If
+              the --pp option is supplied, the process or job identifier of  the
+              job  for  which  the  exit status is returned is assigned to the
+              variable _v_a_r_n_a_m_e named by the  option  argument.   The  variable
+              will  be unset initially, before any assignment.  This is useful
+              only when the --nn option is supplied.  Supplying the  --ff  option,
+              when  job control is enabled, forces wwaaiitt to wait for _i_d to ter-
+              minate before returning its status, instead of returning when it
+              changes  status.  If _i_d specifies a non-existent process or job,
+              the return status is 127.  If wwaaiitt is interrupted by  a  signal,
+              the  return  status will be greater than 128, as described under
+              SSIIGGNNAALLSS above.  Otherwise, the return status is the exit  status
+              of the last process or job waited for.

+SSHHEELLLL CCOOMMPPAATTIIBBIILLIITTYY MMOODDEE
+       Bash-4.0  introduced the concept of a _s_h_e_l_l _c_o_m_p_a_t_i_b_i_l_i_t_y _l_e_v_e_l, speci-
+       fied as a set of options to the shopt  builtin  (  ccoommppaatt3311,  ccoommppaatt3322,
+       ccoommppaatt4400,  ccoommppaatt4411, and so on).  There is only one current compatibil-
+       ity level -- each option  is  mutually  exclusive.   The  compatibility
+       level  is intended to allow users to select behavior from previous ver-
+       sions that is incompatible  with  newer  versions  while  they  migrate
+       scripts  to  use  current  features and behavior. It's intended to be a
+       temporary solution.
+
+       This section does not mention behavior that is standard for a  particu-
+       lar  version  (e.g., setting ccoommppaatt3322 means that quoting the rhs of the
+       regexp matching operator quotes special regexp characters in the  word,
+       which is default behavior in bash-3.2 and subsequent versions).
+
+       If  a  user enables, say, ccoommppaatt3322, it may affect the behavior of other
+       compatibility levels up to  and  including  the  current  compatibility
+       level.   The  idea  is  that each compatibility level controls behavior
+       that changed in that version of bbaasshh, but that behavior may  have  been
+       present  in  earlier versions.  For instance, the change to use locale-
+       based comparisons with the [[[[ command came  in  bash-4.1,  and  earlier
+       versions used ASCII-based comparisons, so enabling ccoommppaatt3322 will enable
+       ASCII-based comparisons as well.  That granularity may  not  be  suffi-
+       cient  for  all uses, and as a result users should employ compatibility
+       levels carefully.  Read the documentation for a particular  feature  to
+       find out the current behavior.
+
+       Bash-4.3  introduced  a new shell variable: BBAASSHH__CCOOMMPPAATT.  The value as-
+       signed to this variable (a decimal version number like 4.2, or an inte-
+       ger  corresponding to the ccoommppaatt_N_N option, like 42) determines the com-
+       patibility level.
+
+       Starting with bash-4.4, Bash has begun deprecating older  compatibility
+       levels.   Eventually, the options will be removed in favor of BBAASSHH__CCOOMM--
+       PPAATT.
+
+       Bash-5.0 is the final version for which there  will  be  an  individual
+       shopt  option for the previous version. Users should use BBAASSHH__CCOOMMPPAATT on
+       bash-5.0 and later versions.
+
+       The following table describes the behavior changes controlled  by  each
+       compatibility level setting.  The ccoommppaatt_N_N tag is used as shorthand for
+       setting the compatibility level to _N_N using one of the following mecha-
+       nisms.   For versions prior to bash-5.0, the compatibility level may be
+       set using the corresponding ccoommppaatt_N_N shopt option.   For  bash-4.3  and
+       later  versions,  the  BBAASSHH__CCOOMMPPAATT variable is preferred, and it is re-
+       quired for bash-5.1 and later versions.

+                     ceived the interrupt, so interrupting one  command  in  a

+                     lation and _s_t_r_c_m_p(3); bash-4.1 and later use the  current
+                     locale's collation sequence and _s_t_r_c_o_l_l(3).

+                     (while/until/etc.)  is not reset, so bbrreeaakk or ccoonnttiinnuuee in
+                     that function will break or continue loops in the calling
+                     context.  Bash-4.4 and later reset the loop state to pre-

+
+       ccoommppaatt4444
+              +o      the shell sets  up  the  values  used  by  BBAASSHH__AARRGGVV  and
+                     BBAASSHH__AARRGGCC  so  they  can expand to the shell's positional
+                     parameters even if extended debugging mode is not enabled
+              +o      a subshell inherits loops from  its  parent  context,  so
+                     bbrreeaakk  or  ccoonnttiinnuuee  will  cause  the  subshell  to exit.
+                     Bash-5.0 and later reset the loop state  to  prevent  the
+                     exit
+              +o      variable  assignments  preceding builtins like eexxppoorrtt and
+                     rreeaaddoonnllyy that set attributes continue to affect variables
+                     with the same name in the calling environment even if the
+                     shell is not in posix mode
+
+       ccoommppaatt5500
+              +o      Bash-5.1 changed the way $$RRAANNDDOOMM is generated  to  intro-
+                     duce slightly more randomness. If the shell compatibility
+                     level is set to 50 or lower, it  reverts  to  the  method
+                     from  bash-5.0 and previous versions, so seeding the ran-
+                     dom number generator by assigning a value to RRAANNDDOOMM  will
+                     produce the same sequence as in bash-5.0
+              +o      If  the  command hash table is empty, bash versions prior
+                     to bash-5.1 printed an informational message to that  ef-
+                     fect,  even  when  producing output that can be reused as
+                     input. Bash-5.1 suppresses that message when the  --ll  op-
+                     tion is supplied.
+
+       ccoommppaatt5511
+              +o      The  uunnsseett  builtin  treats  attempts to unset array sub-
+                     scripts @@ and ** differently depending on whether the  ar-
+                     ray  is  indexed  or associative, and differently than in
+                     previous versions.
+
+RREESSTTRRIICCTTEEDD SSHHEELLLL
+       If bbaasshh is started with the name rrbbaasshh, or the --rr option is supplied at
+       invocation,  the  shell becomes restricted.  A restricted shell is used
+       to set up an environment more controlled than the standard  shell.   It
+       behaves  identically  to bbaasshh with the exception that the following are
+       disallowed or not performed:
+
+       +o      changing directories with ccdd
+
+       +o      setting or unsetting the values of SSHHEELLLL, PPAATTHH,  HHIISSTTFFIILLEE,  EENNVV,
+              or BBAASSHH__EENNVV
+
+       +o      specifying command names containing //
+
+       +o      specifying  a  filename  containing  a // as an argument to the ..
+              builtin command
+
+       +o      specifying a filename containing a slash as an argument  to  the
+              hhiissttoorryy builtin command
+
+       +o      specifying  a  filename containing a slash as an argument to the
+              --pp option to the hhaasshh builtin command
+
+       +o      importing function definitions from  the  shell  environment  at
+              startup
+
+       +o      parsing  the  value  of  SSHHEELLLLOOPPTTSS from the shell environment at
+              startup
+
+       +o      redirecting output using the >, >|, <>, >&, &>, and >> redirect-
+              ion operators
+
+       +o      using the eexxeecc builtin command to replace the shell with another
+              command
+
+       +o      adding or deleting builtin commands with the --ff and  --dd  options
+              to the eennaabbllee builtin command
+
+       +o      using  the  eennaabbllee  builtin  command  to  enable  disabled shell
+              builtins
+
+       +o      specifying the --pp option to the ccoommmmaanndd builtin command
+
+       +o      turning off  restricted  mode  with  sseett  ++rr  or  sshhoopptt  --uu  rree--
+              ssttrriicctteedd__sshheellll.
+
+       These restrictions are enforced after any startup files are read.
+
+       When a command that is found to be a shell script is executed (see CCOOMM--
+       MMAANNDD EEXXEECCUUTTIIOONN above), rrbbaasshh turns off any restrictions  in  the  shell
+       spawned to execute the script.

+BBUUGG RREEPPOORRTTSS
+       If you find a bug in bbaasshh,, you should report it.  But first, you should
+       make  sure  that  it really is a bug, and that it appears in the latest
+       version  of  bbaasshh.   The  latest  version  is  always  available   from
+       _f_t_p_:_/_/_f_t_p_._g_n_u_._o_r_g_/_p_u_b_/_g_n_u_/_b_a_s_h_/          and          _h_t_t_p_:_/_/_g_i_t_._s_a_v_a_n_-
+       _n_a_h_._g_n_u_._o_r_g_/_c_g_i_t_/_b_a_s_h_._g_i_t_/_s_n_a_p_s_h_o_t_/_b_a_s_h_-_m_a_s_t_e_r_._t_a_r_._g_z.
+
+       Once you have determined that a bug actually exists,  use  the  _b_a_s_h_b_u_g
+       command  to submit a bug report.  If you have a fix, you are encouraged
+       to mail that as well!  Suggestions and `philosophical' bug reports  may
+       be  mailed  to  _b_u_g_-_b_a_s_h_@_g_n_u_._o_r_g  or  posted  to  the  Usenet newsgroup
+       ggnnuu..bbaasshh..bbuugg.
+
+       ALL bug reports should include:
+
+       The version number of bbaasshh
+       The hardware and operating system
+       The compiler used to compile
+       A description of the bug behaviour
+       A short script or `recipe' which exercises the bug
+
+       _b_a_s_h_b_u_g inserts the first three items automatically into  the  template
+       it provides for filing a bug report.
+
+       Comments and bug reports concerning this manual page should be directed
+       to _c_h_e_t_._r_a_m_e_y_@_c_a_s_e_._e_d_u.
+
+BBUUGGSS
+       It's too big and too slow.
+
+       There are some subtle differences between bbaasshh and traditional versions
+       of sshh, mostly because of the PPOOSSIIXX specification.
+
+       Aliases are confusing in some uses.
+
+       Shell builtin commands and functions are not stoppable/restartable.
+
+       Compound commands and command sequences of the form `a ; b ; c' are not
+       handled gracefully  when  process  suspension  is  attempted.   When  a
+       process  is stopped, the shell immediately executes the next command in
+       the sequence.  It suffices to place the sequence  of  commands  between
+       parentheses  to  force  it  into  a subshell, which may be stopped as a
+       unit.
+
+       Array variables may not (yet) be exported.
+
+       There may be only one active coprocess at a time.

+.SH NAME
+bash \- GNU Bourne-Again SHell
+.SH SYNOPSIS
+.B bash
+[options]
+[command_string | file]
+.SH COPYRIGHT
+.if n Bash is Copyright (C) 1989-2022 by the Free Software Foundation, Inc.
+.if t Bash is Copyright \(co 1989-2022 by the Free Software Foundation, Inc.
+.SH DESCRIPTION
+.B Bash
+is an \fBsh\fR-compatible command language interpreter that
+executes commands read from the standard input or from a file.
+.B Bash
+also incorporates useful features from the \fIKorn\fP and \fIC\fP
+shells (\fBksh\fP and \fBcsh\fP).
+.PP
+.B Bash
+is intended to be a conformant implementation of the
+Shell and Utilities portion of the IEEE POSIX specification
+(IEEE Standard 1003.1).
+.B Bash
+can be configured to be POSIX-conformant by default.
+.SH OPTIONS
+All of the single-character shell options documented in the
+description of the \fBset\fR builtin command, including \fB\-o\fP,
+can be used as options when the shell is invoked.
+In addition, \fBbash\fR
+interprets the following options when it is invoked:
+.PP
+.PD 0
+.TP 10
+.B \-c
+If the
+.B \-c
+option is present, then commands are read from the first non-option argument
+.IR command_string .
+If there are arguments after the
+.IR command_string ,
+the first argument is assigned to
+.B $0
+and any remaining arguments are assigned to the positional parameters.
+The assignment to
+.B $0
+sets the name of the shell, which is used in warning and error messages.
+.TP
+.B \-i
+If the
+.B \-i
+option is present, the shell is
+.IR interactive .
+.TP
+.B \-l
+Make
+.B bash
+act as if it had been invoked as a login shell (see
+.SM
+.B INVOCATION
+below).
+.TP
+.B \-r
+If the
+.B \-r
+option is present, the shell becomes
+.I restricted
+(see
+.SM
+.B "RESTRICTED SHELL"
+below).
+.TP
+.B \-s
+If the
+.B \-s
+option is present, or if no arguments remain after option
+processing, then commands are read from the standard input.
+This option allows the positional parameters to be set
+when invoking an interactive shell or when reading input
+through a pipe.
+.TP
+.B \-D
+A list of all double-quoted strings preceded by \fB$\fP
+is printed on the standard output.
+These are the strings that
+are subject to language translation when the current locale
+is not \fBC\fP or \fBPOSIX\fP.
+This implies the \fB\-n\fP option; no commands will be executed.
+.TP
+.B [\-+]O [\fIshopt_option\fP]
+\fIshopt_option\fP is one of the shell options accepted by the
+\fBshopt\fP builtin (see
+.SM
+.B SHELL BUILTIN COMMANDS
+below).
+If \fIshopt_option\fP is present, \fB\-O\fP sets the value of that option;
+\fB+O\fP unsets it.
+If \fIshopt_option\fP is not supplied, the names and values of the shell
+options accepted by \fBshopt\fP are printed on the standard output.
+If the invocation option is \fB+O\fP, the output is displayed in a format
+that may be reused as input.
+.TP
+.B \-\-
+A
+.B \-\-
+signals the end of options and disables further option processing.
+Any arguments after the
+.B \-\-
+are treated as filenames and arguments.  An argument of
+.B \-
+is equivalent to \fB\-\-\fP.
+.PD
+.PP
+.B Bash
+also interprets a number of multi-character options.
+These options must appear on the command line before the
+single-character options to be recognized.
+.PP
+.PD 0
+.TP
+.B \-\-debugger
+Arrange for the debugger profile to be executed before the shell
+starts.
+Turns on extended debugging mode (see the description of the
+.B extdebug
+option to the
+.B shopt
+builtin below).
+.TP
+.B \-\-dump\-po\-strings
+Equivalent to \fB\-D\fP, but the output is in the GNU \fIgettext\fP
+\fBpo\fP (portable object) file format.
+.TP
+.B \-\-dump\-strings
+Equivalent to \fB\-D\fP.
+.TP
+.B \-\-help
+Display a usage message on standard output and exit successfully.
+.TP
+\fB\-\-init\-file\fP \fIfile\fP
+.PD 0
+.TP
+\fB\-\-rcfile\fP \fIfile\fP
+.PD
+Execute commands from
+.I file
+instead of the standard personal initialization file
+.I ~/.bashrc
+if the shell is interactive (see
+.SM
+.B INVOCATION
+below).
+.TP
+.B \-\-login
+Equivalent to \fB\-l\fP.
+.TP
+.B \-\-noediting
+Do not use the GNU
+.B readline
+library to read command lines when the shell is interactive.
+.TP
+.B \-\-noprofile
+Do not read either the system-wide startup file
+.FN /etc/profile
+or any of the personal initialization files
+.IR ~/.bash_profile ,
+.IR ~/.bash_login ,
+or
+.IR ~/.profile .
+By default,
+.B bash
+reads these files when it is invoked as a login shell (see
+.SM
+.B INVOCATION
+below).
+.TP
+.B \-\-norc
+Do not read and execute the personal initialization file
+.I ~/.bashrc
+if the shell is interactive.
+This option is on by default if the shell is invoked as
+.BR sh .
+.TP
+.B \-\-posix
+Change the behavior of \fBbash\fP where the default operation differs
+from the POSIX standard to match the standard (\fIposix mode\fP).
+See
+.SM
+.B "SEE ALSO"
+below for a reference to a document that details how posix mode affects
+bash's behavior.
+.TP
+.B \-\-restricted
+The shell becomes restricted (see
+.SM
+.B "RESTRICTED SHELL"
+below).
+.TP
+.B \-\-verbose
+Equivalent to \fB\-v\fP.
+.TP
+.B \-\-version
+Show version information for this instance of
+.B bash
+on the standard output and exit successfully.
+.PD
+.SH ARGUMENTS
+If arguments remain after option processing, and neither the
+.B \-c
+nor the
+.B \-s
+option has been supplied, the first argument is assumed to
+be the name of a file containing shell commands.
+If
+.B bash
+is invoked in this fashion,
+.B $0
+is set to the name of the file, and the positional parameters
+are set to the remaining arguments.
+.B Bash
+reads and executes commands from this file, then exits.
+\fBBash\fP's exit status is the exit status of the last command
+executed in the script.
+If no commands are executed, the exit status is 0.
+An attempt is first made to open the file in the current directory, and,
+if no file is found, then the shell searches the directories in
+.SM
+.B PATH
+for the script.
+.SH INVOCATION
+A \fIlogin shell\fP is one whose first character of argument zero is a
+.BR \- ,
+or one started with the
+.B \-\-login
+option.
+.PP
+An \fIinteractive\fP shell is one started without non-option arguments
+(unless \fB\-s\fP is specified)
+and without the
+.B \-c
+option,
+whose standard input and error are
+both connected to terminals (as determined by
+.IR isatty (3)),
+or one started with the
+.B \-i
+option.
+.SM
+.B PS1
+is set and
+.B $\-
+includes
+.B i
+if
+.B bash
+is interactive,
+allowing a shell script or a startup file to test this state.
+.PP
+The following paragraphs describe how
+.B bash
+executes its startup files.
+If any of the files exist but cannot be read,
+.B bash
+reports an error.
+Tildes are expanded in filenames as described below under
+.B "Tilde Expansion"
+in the
+.SM
+.B EXPANSION
+section.
+.PP
+When
+.B bash
+is invoked as an interactive login shell, or as a non-interactive shell
+with the \fB\-\-login\fP option, it first reads and
+executes commands from the file \fI/etc/profile\fP, if that
+file exists.
+After reading that file, it looks for \fI~/.bash_profile\fP,
+\fI~/.bash_login\fP, and \fI~/.profile\fP, in that order, and reads
+and executes commands from the first one that exists and is readable.
+The
+.B \-\-noprofile
+option may be used when the shell is started to inhibit this behavior.
+.PP
+When an interactive login shell exits,
+or a non-interactive login shell executes the \fBexit\fP builtin command,
+.B bash
+reads and executes commands from the file \fI~/.bash_logout\fP, if it
+exists.
+.PP
+When an interactive shell that is not a login shell is started,
+.B bash
+reads and executes commands from \fI~/.bashrc\fP, if that file exists.
+This may be inhibited by using the
+.B \-\-norc
+option.
+The \fB\-\-rcfile\fP \fIfile\fP option will force
+.B bash
+to read and execute commands from \fIfile\fP instead of \fI~/.bashrc\fP.
+.PP
+When
+.B bash
+is started non-interactively, to run a shell script, for example, it
+looks for the variable
+.SM
+.B BASH_ENV
+in the environment, expands its value if it appears there, and uses the
+expanded value as the name of a file to read and execute.
+.B Bash
+behaves as if the following command were executed:
+.sp .5
+.RS
+.if t \f(CWif [ \-n "$BASH_ENV" ]; then . "$BASH_ENV"; fi\fP
+.if n if [ \-n "$BASH_ENV" ]; then . "$BASH_ENV"; fi
+.RE
+.sp .5
+but the value of the
+.SM
+.B PATH
+variable is not used to search for the filename.
+.PP
+If
+.B bash
+is invoked with the name
+.BR sh ,
+it tries to mimic the startup behavior of historical versions of
+.B sh
+as closely as possible,
+while conforming to the POSIX standard as well.
+When invoked as an interactive login shell, or a non-interactive
+shell with the \fB\-\-login\fP option, it first attempts to
+read and execute commands from
+.I /etc/profile
+and
+.IR ~/.profile ,
+in that order.
+The
+.B \-\-noprofile
+option may be used to inhibit this behavior.
+When invoked as an interactive shell with the name
+.BR sh ,
+.B bash
+looks for the variable
+.SM

+.SH "SHELL GRAMMAR"
+This section describes the syntax of the various forms of shell commands.
+.SS Simple Commands
+A \fIsimple command\fP is a sequence of optional variable assignments
+followed by \fBblank\fP-separated words and redirections, and
+terminated by a \fIcontrol operator\fP.  The first word
+specifies the command to be executed, and is passed as argument zero.
+The remaining words are passed as arguments to the invoked command.
+.PP
+The return value of a \fIsimple command\fP is its exit status, or
+128+\fIn\^\fP if the command is terminated by signal
+.IR n .
+.SS Pipelines
+A \fIpipeline\fP is a sequence of one or more commands separated by
+one of the control operators
+.B |
+or \fB|&\fP.
+The format for a pipeline is:
+.RS
+.PP
+[\fBtime\fP [\fB\-p\fP]] [ ! ] \fIcommand1\fP [ [\fB|\fP\(bv\fB|&\fP] \fIcommand2\fP ... ]
+.RE
+.PP
+The standard output of
+.I command1
+is connected via a pipe to the standard input of
+.IR command2 .
+This connection is performed before any redirections specified by the
+.IR command1 (see
+.SM
+.B REDIRECTION
+below).
+If \fB|&\fP is used, \fIcommand1\fP's standard error, in addition to its
+standard output, is connected to
+\fIcommand2\fP's standard input through the pipe;
+it is shorthand for \fB2>&1 |\fP.
+This implicit redirection of the standard error to the standard output is
+performed after any redirections specified by \fIcommand1\fP.
+.PP
+The return status of a pipeline is the exit status of the last
+command, unless the \fBpipefail\fP option is enabled.
+If \fBpipefail\fP is enabled, the pipeline's return status is the
+value of the last (rightmost) command to exit with a non-zero status,
+or zero if all commands exit successfully.
+If the reserved word
+.B !
+precedes a pipeline, the exit status of that pipeline is the logical
+negation of the exit status as described above.
+The shell waits for all commands in the pipeline to
+terminate before returning a value.
+.PP
+If the
+.B time
+reserved word precedes a pipeline, the elapsed as well as user and
+system time consumed by its execution are reported when the pipeline
+terminates.
+The \fB\-p\fP option changes the output format to that specified by POSIX.
+When the shell is in \fIposix mode\fP, it does not recognize
+\fBtime\fP as a reserved word if the next token begins with a `-'.
+The
+.SM
+.B TIMEFORMAT
+variable may be set to a format string that specifies how the timing
+information should be displayed; see the description of
+.SM
+.B TIMEFORMAT
+under
+.B "Shell Variables"
+below.
+.PP
+When the shell is in \fIposix mode\fP, \fBtime\fP
+may be followed by a newline.  In this case, the shell displays the
+total user and system time consumed by the shell and its children.
+The
+.SM
+.B TIMEFORMAT
+variable may be used to specify the format of
+the time information.
+.PP
+Each command in a multi-command pipeline,
+where pipes are created,
+is executed in a \fIsubshell\fP, which is a
+separate process.
+See
+.SM
+\fBCOMMAND EXECUTION ENVIRONMENT\fP
+for a description of subshells and a subshell environment.
+If the \fBlastpipe\fP option is enabled using the \fBshopt\fP builtin
+(see the description of \fBshopt\fP below),
+the last element of a pipeline may be run by the shell process
+when job control is not active.
+.SS Lists
+A \fIlist\fP is a sequence of one or more pipelines separated by one
+of the operators
+.BR ; ,
+.BR & ,
+.BR && ,
+or
+.BR || ,
+and optionally terminated by one of
+.BR ; ,
+.BR & ,
+or
+.BR <newline> .
+.PP
+Of these list operators,
+.B &&
+and
+.B ||
+have equal precedence, followed by
+.B ;
+and
+.BR & ,
+which have equal precedence.
+.PP
+A sequence of one or more newlines may appear in a \fIlist\fP instead
+of a semicolon to delimit commands.
+.PP
+If a command is terminated by the control operator
+.BR & ,
+the shell executes the command in the \fIbackground\fP
+in a subshell.
+The shell does not wait for the command to
+finish, and the return status is 0.
+These are referred to as \fIasynchronous\fP commands.
+Commands separated by a
+.B ;
+are executed sequentially; the shell waits for each
+command to terminate in turn.  The return status is the
+exit status of the last command executed.
+.PP
+AND and OR lists are sequences of one or more pipelines separated by the
+\fB&&\fP and \fB||\fP control operators, respectively.
+AND and OR lists are executed with left associativity.
+An AND list has the form
+.RS
+.PP
+\fIcommand1\fP \fB&&\fP \fIcommand2\fP
+.RE
+.PP
+.I command2
+is executed if, and only if,
+.I command1
+returns an exit status of zero (success).
+.PP
+An OR list has the form
+.RS
+.PP
+\fIcommand1\fP \fB||\fP \fIcommand2\fP
+.RE
+.PP
+.I command2
+is executed if, and only if,
+.I command1
+returns a non-zero exit status.
+The return status of
+AND and OR lists is the exit status of the last command
+executed in the list.
+.SS Compound Commands
+A \fIcompound command\fP is one of the following.
+In most cases a \fIlist\fP in a command's description may be separated from
+the rest of the command by one or more newlines, and may be followed by a
+newline in place of a semicolon.
+.TP
+(\fIlist\fP)
+\fIlist\fP is executed in a subshell (see
+.SM
+\fBCOMMAND EXECUTION ENVIRONMENT\fP
+below for a description of a subshell environment).
+Variable assignments and builtin
+commands that affect the shell's environment do not remain in effect
+after the command completes.  The return status is the exit status of
+\fIlist\fP.
+.TP
+{ \fIlist\fP; }
+\fIlist\fP is simply executed in the current shell environment.
+\fIlist\fP must be terminated with a newline or semicolon.
+This is known as a \fIgroup command\fP.
+The return status is the exit status of
+\fIlist\fP.
+Note that unlike the metacharacters \fB(\fP and \fB)\fP, \fB{\fP and
+\fB}\fP are \fIreserved words\fP and must occur where a reserved
+word is permitted to be recognized.  Since they do not cause a word
+break, they must be separated from \fIlist\fP by whitespace or another
+shell metacharacter.
+.TP
+((\fIexpression\fP))
+The \fIexpression\fP is evaluated according to the rules described
+below under
+.SM
+.BR "ARITHMETIC EVALUATION" .
+If the value of the expression is non-zero, the return status is 0;
+otherwise the return status is 1.
+The \fIexpression\fP
+undergoes the same expansions
+as if it were within double quotes,
+but double quote characters in \fIexpression\fP are not treated specially
+and are removed.
+.TP
+\fB[[\fP \fIexpression\fP \fB]]\fP
+Return a status of 0 or 1 depending on the evaluation of
+the conditional expression \fIexpression\fP.
+Expressions are composed of the primaries described below under
+.SM
+.BR "CONDITIONAL EXPRESSIONS" .
+The words between the \fB[[\fP and \fB]]\fP do not undergo word splitting
+and pathname expansion.
+The shell performs tilde expansion, parameter and
+variable expansion, arithmetic expansion, command substitution, process
+substitution, and quote removal on those words
+(the expansions that would occur if the words were enclosed in double quotes).
+Conditional operators such as \fB\-f\fP must be unquoted to be recognized
+as primaries.
+.if t .sp 0.5
+.if n .sp 1
+When used with \fB[[\fP, the \fB<\fP and \fB>\fP operators sort
+lexicographically using the current locale.
+.if t .sp 0.5
+.if n .sp 1
+When the \fB==\fP and \fB!=\fP operators are used, the string to the
+right of the operator is considered a pattern and matched according
+to the rules described below under \fBPattern Matching\fP,
+as if the \fBextglob\fP shell option were enabled.
+The \fB=\fP operator is equivalent to \fB==\fP.
+If the
+.B nocasematch
+shell option is enabled, the match is performed without regard to the case
+of alphabetic characters.
+The return value is 0 if the string matches (\fB==\fP) or does not match
+(\fB!=\fP) the pattern, and 1 otherwise.
+Any part of the pattern may be quoted to force the quoted portion
+to be matched as a string.
+.if t .sp 0.5
+.if n .sp 1
+An additional binary operator, \fB=~\fP, is available, with the same
+precedence as \fB==\fP and \fB!=\fP.
+When it is used, the string to the right of the operator is considered
+a POSIX extended regular expression and matched accordingly
+(using the POSIX \fIregcomp\fP and \fIregexec\fP interfaces
+usually described in \fIregex\fP(3)).
+The return value is 0 if the string matches
+the pattern, and 1 otherwise.
+If the regular expression is syntactically incorrect, the conditional
+expression's return value is 2.
+If the
+.B nocasematch
+shell option is enabled, the match is performed without regard to the case
+of alphabetic characters.
+If any part of the pattern is quoted, the quoted portion is matched literally.
+This means every character in the quoted portion matches itself,
+instead of having any special pattern matching meaning.
+If the pattern is stored in a shell variable, quoting the variable
+expansion forces the entire pattern to be matched literally.
+Treat bracket expressions in regular expressions carefully,
+since normal quoting and pattern characters lose their meanings
+between brackets.
+.if t .sp 0.5
+.if n .sp 1
+The pattern will match if it matches any part of the string.
+Anchor the pattern using the \fB^\fP and \fB$\fP regular expression
+operators to force it to match the entire string.
+The array variable
+.SM
+.B BASH_REMATCH
+records which parts of the string matched the pattern.
+The element of
+.SM
+.B BASH_REMATCH
+with index 0 contains the portion of
+the string matching the entire regular expression.
+Substrings matched by parenthesized subexpressions within the regular
+expression are saved in the remaining
+.SM
+.B BASH_REMATCH
+indices. The element of
+.SM
+.B BASH_REMATCH
+with index \fIn\fP is the portion of the
+string matching the \fIn\fPth parenthesized subexpression.
+Bash sets
+.SM
+.B BASH_REMATCH
+in the global scope; declaring it as a local variable will lead to
+unexpected results.
+.if t .sp 0.5
+.if n .sp 1
+Expressions may be combined using the following operators, listed
+in decreasing order of precedence:
+.if t .sp 0.5
+.if n .sp 1
+.RS
+.PD 0
+.TP
+.B ( \fIexpression\fP )
+Returns the value of \fIexpression\fP.

+True if either
+.I expression1
+or
+.I expression2
+is true.
+.PD
+.LP
+The \fB&&\fP and \fB||\fP

+\fIexpression1\fP is sufficient to determine the return value of
+the entire conditional expression.
+.RE
+.TP
+\fBfor\fP \fIname\fP [ [ \fBin\fP [ \fIword ...\fP ] ] ; ] \fBdo\fP \fIlist\fP ; \fBdone\fP
+The list of words following \fBin\fP is expanded, generating a list
+of items.
+The variable \fIname\fP is set to each element of this list
+in turn, and \fIlist\fP is executed each time.
+If the \fBin\fP \fIword\fP is omitted, the \fBfor\fP command executes
+\fIlist\fP once for each positional parameter that is set (see
+.SM
+.B PARAMETERS
+below).
+The return status is the exit status of the last command that executes.
+If the expansion of the items following \fBin\fP results in an empty
+list, no commands are executed, and the return status is 0.
+.TP
+\fBfor\fP (( \fIexpr1\fP ; \fIexpr2\fP ; \fIexpr3\fP )) ; \fBdo\fP \fIlist\fP ; \fBdone\fP
+First, the arithmetic expression \fIexpr1\fP is evaluated according
+to the rules described below under
+.SM
+.BR "ARITHMETIC EVALUATION" .
+The arithmetic expression \fIexpr2\fP is then evaluated repeatedly
+until it evaluates to zero.
+Each time \fIexpr2\fP evaluates to a non-zero value, \fIlist\fP is
+executed and the arithmetic expression \fIexpr3\fP is evaluated.
+If any expression is omitted, it behaves as if it evaluates to 1.
+The return value is the exit status of the last command in \fIlist\fP
+that is executed, or false if any of the expressions is invalid.
+.TP
+\fBselect\fP \fIname\fP [ \fBin\fP \fIword\fP ] ; \fBdo\fP \fIlist\fP ; \fBdone\fP
+The list of words following \fBin\fP is expanded, generating a list
+of items, and the set of expanded words is printed on the standard
+error, each preceded by a number.  If the \fBin\fP
+\fIword\fP is omitted, the positional parameters are printed (see
+.SM
+.B PARAMETERS
+below).
+.B select
+then displays the
+.SM
+.B PS3
+prompt and reads a line from the standard input.
+If the line consists of a number corresponding to one of
+the displayed words, then the value of
+.I name
+is set to that word.
+If the line is empty, the words and prompt are displayed again.
+If EOF is read, the \fBselect\fP command completes and returns 1.
+Any other value read causes
+.I name
+to be set to null.  The line read is saved in the variable
+.SM
+.BR REPLY .
+The
+.I list
+is executed after each selection until a
+.B break
+command is executed.
+The exit status of
+.B select
+is the exit status of the last command executed in
+.IR list ,
+or zero if no commands were executed.
+.TP
+\fBcase\fP \fIword\fP \fBin\fP [ [(] \fIpattern\fP [ \fB|\fP \fIpattern\fP ] \

+A \fBcase\fP command first expands \fIword\fP, and tries to match
+it against each \fIpattern\fP in turn, using the matching rules
+described under
+.B Pattern Matching
+below.
+The \fIword\fP is expanded using tilde
+expansion, parameter and variable expansion, arithmetic expansion,
+command substitution, process substitution and quote removal.
+Each \fIpattern\fP examined is expanded using tilde
+expansion, parameter and variable expansion, arithmetic expansion,
+command substitution, process substitution, and quote removal.
+If the

+shell option is enabled, the match is performed without regard to the case
+of alphabetic characters.
+When a match is found, the corresponding \fIlist\fP is executed.
+If the \fB;;\fP operator is used, no subsequent matches are attempted after
+the first pattern match.
+Using \fB;&\fP in place of \fB;;\fP causes execution to continue with
+the \fIlist\fP associated with the next set of patterns.
+Using \fB;;&\fP in place of \fB;;\fP causes the shell to test the next
+pattern list in the statement, if any, and execute any associated \fIlist\fP

+.SS Coprocesses
+A \fIcoprocess\fP is a shell command preceded by the \fBcoproc\fP reserved
+word.
+A coprocess is executed asynchronously in a subshell, as if the command
+had been terminated with the \fB&\fP control operator, with a two-way pipe
+established between the executing shell and the coprocess.
+.PP
+The syntax for a coprocess is:
+.RS
+.PP
+\fBcoproc\fP [\fINAME\fP] \fIcommand\fP [\fIredirections\fP]
+.RE
+.PP
+This creates a coprocess named \fINAME\fP.
+\fIcommand\fP may be either a simple command or a compound
+command (see above).
+\fINAME\fP is a shell variable name.
+If \fINAME\fP is not supplied, the default name is \fBCOPROC\fP.
+.PP
+The recommended form to use for a coprocess is
+.RS
+.PP
+\fBcoproc\fP \fINAME\fP { \fIcommand\fP [\fIredirections\fP]; }
+.RE
+.PP
+This form is recommended because simple commands result in the coprocess
+always being named \fBCOPROC\fP, and it is simpler to use and more complete
+than the other compound commands.
+.PP
+If \fIcommand\fP is a compound command, \fINAME\fP is optional. The
+word following \fBcoproc\fP determines whether that word is interpreted
+as a variable name: it is interpreted as \fINAME\fP if it is not a
+reserved word that introduces a compound command.
+If \fIcommand\fP is a simple command, \fINAME\fP is not allowed; this
+is to avoid confusion between \fINAME\fP and the first word of the simple
+command.
+.PP
+When the coprocess is executed, the shell creates an array variable (see
+.B Arrays
+below) named \fINAME\fP in the context of the executing shell.
+The standard output of
+.I command
+is connected via a pipe to a file descriptor in the executing shell,
+and that file descriptor is assigned to \fINAME\fP[0].
+The standard input of
+.I command
+is connected via a pipe to a file descriptor in the executing shell,
+and that file descriptor is assigned to \fINAME\fP[1].
+This pipe is established before any redirections specified by the
+command (see
+.SM
+.B REDIRECTION
+below).
+The file descriptors can be utilized as arguments to shell commands
+and redirections using standard word expansions.
+Other than those created to execute command and process substitutions,
+the file descriptors are not available in subshells.
+.PP
+The process ID of the shell spawned to execute the coprocess is
+available as the value of the variable \fINAME\fP_PID.
+The \fBwait\fP
+builtin command may be used to wait for the coprocess to terminate.
+.PP
+Since the coprocess is created as an asynchronous command,
+the \fBcoproc\fP command always returns success.
+The return status of a coprocess is the exit status of \fIcommand\fP.
+.SS Shell Function Definitions
+A shell function is an object that is called like a simple command and
+executes a compound command with a new set of positional parameters.
+Shell functions are declared as follows:
+.TP
+\fIfname\fP () \fIcompound\-command\fP [\fIredirection\fP]
+.PD 0
+.TP
+\fBfunction\fP \fIfname\fP [()] \fIcompound\-command\fP [\fIredirection\fP]
+.PD
+This defines a function named \fIfname\fP.
+The reserved word \fBfunction\fP is optional.
+If the \fBfunction\fP reserved word is supplied, the parentheses are optional.
+The \fIbody\fP of the function is the compound command
+.I compound\-command
+(see \fBCompound Commands\fP above).
+That command is usually a \fIlist\fP of commands between { and }, but
+may be any command listed under \fBCompound Commands\fP above.
+If the \fBfunction\fP reserved word is used, but the
+parentheses are not supplied, the braces are recommended.
+\fIcompound\-command\fP is executed whenever \fIfname\fP is specified as the
+name of a simple command.
+When in \fIposix mode\fP, \fIfname\fP must be a valid shell \fIname\fP
+and may not be the name of one of the
+POSIX \fIspecial builtins\fP.
+In default mode, a function name can be any unquoted shell word that does
+not contain \fB$\fP.
+Any redirections (see
+.SM
+.B REDIRECTION
+below) specified when a function is defined are performed
+when the function is executed.
+The exit status of a function definition is zero unless a syntax error
+occurs or a readonly function with the same name already exists.
+When executed, the exit status of a function is the exit status of the
+last command executed in the body.  (See
+.SM
+.B FUNCTIONS
+below.)
+.SH COMMENTS
+In a non-interactive shell, or an interactive shell in which the
+.B interactive_comments
+option to the
+.B shopt
+builtin is enabled (see
+.SM
+.B "SHELL BUILTIN COMMANDS"
+below), a word beginning with
+.B #
+causes that word and all remaining characters on that line to
+be ignored.  An interactive shell without the
+.B interactive_comments
+option enabled does not allow comments.  The
+.B interactive_comments
+option is on by default in interactive shells.
+.SH QUOTING
+\fIQuoting\fP is used to remove the special meaning of certain
+characters or words to the shell.  Quoting can be used to
+disable special treatment for special characters, to prevent
+reserved words from being recognized as such, and to prevent
+parameter expansion.
+.PP
+Each of the \fImetacharacters\fP listed above under
+.SM
+.B DEFINITIONS
+has special meaning to the shell and must be quoted if it is to
+represent itself.
+.PP
+When the command history expansion facilities are being used
+(see
+.SM
+.B HISTORY EXPANSION
+below), the
+\fIhistory expansion\fP character, usually \fB!\fP, must be quoted
+to prevent history expansion.
+.PP
+There are three quoting mechanisms: the
+.IR "escape character" ,
+single quotes, and double quotes.
+.PP
+A non-quoted backslash (\fB\e\fP) is the
+.IR "escape character" .
+It preserves the literal value of the next character that follows,
+with the exception of <newline>.  If a \fB\e\fP<newline> pair
+appears, and the backslash is not itself quoted, the \fB\e\fP<newline>
+is treated as a line continuation (that is, it is removed from the
+input stream and effectively ignored).
+.PP
+Enclosing characters in single quotes preserves the literal value
+of each character within the quotes.  A single quote may not occur
+between single quotes, even when preceded by a backslash.
+.PP
+Enclosing characters in double quotes preserves the literal value
+of all characters within the quotes, with the exception of
+.BR $ ,
+.BR \` ,
+.BR \e ,
+and, when history expansion is enabled,
+.BR ! .
+When the shell is in \fIposix mode\fP, the \fB!\fP has no special meaning
+within double quotes, even when history expansion is enabled.
+The characters
+.B $
+and
+.B \`
+retain their special meaning within double quotes.  The backslash
+retains its special meaning only when followed by one of the following
+characters:
+.BR $ ,
+.BR \` ,
+\^\fB"\fP\^,
+.BR \e ,
+or
+.BR <newline> .
+A double quote may be quoted within double quotes by preceding it with
+a backslash.
+If enabled, history expansion will be performed unless an
+.B !
+appearing in double quotes is escaped using a backslash.
+The backslash preceding the
+.B !
+is not removed.
+.PP
+The special parameters
+.B *
+and
+.B @
+have special meaning when in double
+quotes (see
+.SM
+.B PARAMETERS
+below).
+.PP
+Character sequences of the form \fB$\fP\(aq\fIstring\fP\(aq are treated
+as a special variant of single quotes.
+The sequence expands to \fIstring\fP, with backslash-escaped characters
+in \fIstring\fP replaced as specified by the ANSI C standard.

+The expanded result is single-quoted, as if the dollar sign had

+.PP
+A double-quoted string preceded by a dollar sign (\fB$\fP\(dq\fIstring\fP\(dq)
+will cause the string to be translated according to the current locale.
+The \fIgettext\fP infrastructure performs the lookup and
+translation, using the \fBLC_MESSAGES\fP, \fBTEXTDOMAINDIR\fP,
+and \fBTEXTDOMAIN\fP shell variables.
+If the current locale is \fBC\fP or \fBPOSIX\fP,
+if there are no translations available,
+or if the string is not translated,
+the dollar sign is ignored.
+This is a form of double quoting, so the string remains double-quoted
+by default, whether or not it is translated and replaced.
+If the \fBnoexpand_translation\fP option is enabled
+using the \fBshopt\fP builtin,
+translated strings are single-quoted instead of double-quoted.
+See the description of
+.B shopt
+below under
+.SM
+.BR SHELL BUILTIN COMMANDS .
+.SH PARAMETERS
+A
+.I parameter
+is an entity that stores values.
+It can be a
+.IR name ,
+a number, or one of the special characters listed below under
+.BR "Special Parameters" .
+A
+.I variable
+is a parameter denoted by a
+.IR name .
+A variable has a \fIvalue\fP and zero or more \fIattributes\fP.
+Attributes are assigned using the
+.B declare
+builtin command (see
+.B declare
+below in
+.SM
+.BR "SHELL BUILTIN COMMANDS" ).
+.PP
+A parameter is set if it has been assigned a value.  The null string is
+a valid value.  Once a variable is set, it may be unset only by using
+the
+.B unset
+builtin command (see
+.SM
+.B SHELL BUILTIN COMMANDS
+below).
+.PP
+A
+.I variable
+may be assigned to by a statement of the form
+.RS
+.PP
+\fIname\fP=[\fIvalue\fP]
+.RE
+.PP
+If
+.I value
+is not given, the variable is assigned the null string.  All
+.I values
+undergo tilde expansion, parameter and variable expansion,
+command substitution, arithmetic expansion, and quote
+removal (see
+.SM
+.B EXPANSION
+below).  If the variable has its
+.B integer
+attribute set, then
+.I value
+is evaluated as an arithmetic expression even if the $((...)) expansion is
+not used (see
+.B "Arithmetic Expansion"
+below).
+Word splitting and pathname expansion are not performed.
+Assignment statements may also appear as arguments to the
+.BR alias ,
+.BR declare ,
+.BR typeset ,
+.BR export ,
+.BR readonly ,
+and
+.B local
+builtin commands (\fIdeclaration\fP commands).
+When in \fIposix mode\fP, these builtins may appear in a command after
+one or more instances of the \fBcommand\fP builtin and retain these
+assignment statement properties.
+.PP
+In the context where an assignment statement is assigning a value
+to a shell variable or array index, the += operator can be used to
+append to or add to the variable's previous value.
+This includes arguments to builtin commands such as \fBdeclare\fP that
+accept assignment statements (\fIdeclaration\fP commands).
+When += is applied to a variable for which the \fBinteger\fP attribute has been
+set, \fIvalue\fP is evaluated as an arithmetic expression and added to the
+variable's current value, which is also evaluated.
+When += is applied to an array variable using compound assignment (see
+.B Arrays
+below), the
+variable's value is not unset (as it is when using =), and new values are
+appended to the array beginning at one greater than the array's maximum index
+(for indexed arrays) or added as additional key\-value pairs in an
+associative array.
+When applied to a string-valued variable, \fIvalue\fP is expanded and
+appended to the variable's value.
+.PP
+A variable can be assigned the \fInameref\fP attribute using the
+\fB\-n\fP option to the \fBdeclare\fP or \fBlocal\fP builtin commands
+(see the descriptions of \fBdeclare\fP and \fBlocal\fP below)
+to create a \fInameref\fP, or a reference to another variable.
+This allows variables to be manipulated indirectly.
+Whenever the nameref variable is referenced, assigned to, unset, or has
+its attributes modified (other than using or changing the \fInameref\fP
+attribute itself), the
+operation is actually performed on the variable specified by the nameref
+variable's value.
+A nameref is commonly used within shell functions to refer to a variable
+whose name is passed as an argument to the function.
+For instance, if a variable name is passed to a shell function as its first
+argument, running
+.sp .5
+.RS
+.if t \f(CWdeclare -n ref=$1\fP
+.if n declare -n ref=$1
+.RE
+.sp .5
+inside the function creates a nameref variable \fBref\fP whose value is
+the variable name passed as the first argument.
+References and assignments to \fBref\fP, and changes to its attributes,
+are treated as references, assignments, and attribute modifications
+to the variable whose name was passed as \fB$1\fP.
+If the control variable in a \fBfor\fP loop has the nameref attribute,
+the list of words can be a list of shell variables, and a name reference
+will be established for each word in the list, in turn, when the loop is
+executed.
+Array variables cannot be given the \fBnameref\fP attribute.
+However, nameref variables can reference array variables and subscripted
+array variables.
+Namerefs can be unset using the \fB\-n\fP option to the \fBunset\fP builtin.
+Otherwise, if \fBunset\fP is executed with the name of a nameref variable
+as an argument, the variable referenced by the nameref variable will be unset.
+.SS Positional Parameters
+A
+.I positional parameter
+is a parameter denoted by one or more
+digits, other than the single digit 0.  Positional parameters are
+assigned from the shell's arguments when it is invoked,
+and may be reassigned using the
+.B set
+builtin command.  Positional parameters may not be assigned to
+with assignment statements.  The positional parameters are
+temporarily replaced when a shell function is executed (see
+.SM
+.B FUNCTIONS
+below).
+.PP
+When a positional parameter consisting of more than a single
+digit is expanded, it must be enclosed in braces (see
+.SM
+.B EXPANSION
+below).
+.SS Special Parameters
+The shell treats several parameters specially.  These parameters may
+only be referenced; assignment to them is not allowed.
+.PD 0
+.TP
+.B *
+Expands to the positional parameters, starting from one.
+When the expansion is not within double quotes, each positional parameter
+expands to a separate word.
+In contexts where it is performed, those words
+are subject to further word splitting and pathname expansion.
+When the expansion occurs within double quotes, it expands to a single word
+with the value of each parameter separated by the first character of the
+.SM
+.B IFS
+special variable.  That is, "\fB$*\fP" is equivalent
+to "\fB$1\fP\fIc\fP\fB$2\fP\fIc\fP\fB...\fP", where
+.I c
+is the first character of the value of the
+.SM
+.B IFS
+variable.  If
+.SM
+.B IFS
+is unset, the parameters are separated by spaces.
+If
+.SM
+.B IFS
+is null, the parameters are joined without intervening separators.
+.TP
+.B @
+Expands to the positional parameters, starting from one.
+In contexts where word splitting is performed, this expands each
+positional parameter to a separate word; if not within double
+quotes, these words are subject to word splitting.
+In contexts where word splitting is not performed,
+this expands to a single word
+with each positional parameter separated by a space.
+When the
+expansion occurs within double quotes, each parameter expands to a
+separate word.  That is, "\fB$@\fP" is equivalent to
+"\fB$1\fP" "\fB$2\fP" ...
+If the double-quoted expansion occurs within a word, the expansion of
+the first parameter is joined with the beginning part of the original
+word, and the expansion of the last parameter is joined with the last
+part of the original word.
+When there are no positional parameters, "\fB$@\fP" and
+.B $@
+expand to nothing (i.e., they are removed).
+.TP
+.B #
+Expands to the number of positional parameters in decimal.
+.TP
+.B ?
+Expands to the exit status of the most recently executed foreground
+pipeline.
+.TP
+.B \-
+Expands to the current option flags as specified upon invocation,
+by the
+.B set
+builtin command, or those set by the shell itself
+(such as the
+.B \-i
+option).
+.TP
+.B $
+Expands to the process ID of the shell. In a subshell, it
+expands to the process ID of the current shell, not the
+subshell.
+.TP
+.B !
+Expands to the process ID of the job most recently placed into the
+background, whether executed as an asynchronous command or using
+the \fBbg\fP builtin (see
+.SM
+.B "JOB CONTROL"
+below).
+.TP
+.B 0
+Expands to the name of the shell or shell script.  This is set at
+shell initialization.  If
+.B bash
+is invoked with a file of commands,
+.B $0
+is set to the name of that file.  If
+.B bash
+is started with the
+.B \-c
+option, then
+.B $0
+is set to the first argument after the string to be
+executed, if one is present.  Otherwise, it is set
+to the filename used to invoke
+.BR bash ,
+as given by argument zero.
+.PD
+.SS Shell Variables
+The following variables are set by the shell:
+.PP
+.PD 0
+.TP
+.B _
+At shell startup, set to the pathname used to invoke the
+shell or shell script being executed as passed in the environment
+or argument list.
+Subsequently, expands to the last argument to the previous simple
+command executed in the foreground, after expansion.
+Also set to the full pathname used to invoke each command executed
+and placed in the environment exported to that command.
+When checking mail, this parameter holds the name of the mail file
+currently being checked.
+.TP
+.B BASH
+Expands to the full filename used to invoke this instance of
+.BR bash .
+.TP
+.B BASHOPTS
+A colon-separated list of enabled shell options.  Each word in
+the list is a valid argument for the
+.B \-s
+option to the
+.B shopt
+builtin command (see
+.SM
+.B "SHELL BUILTIN COMMANDS"
+below).  The options appearing in
+.SM
+.B BASHOPTS
+are those reported as
+.I on
+by \fBshopt\fP.
+If this variable is in the environment when
+.B bash
+starts up, each shell option in the list will be enabled before
+reading any startup files.
+This variable is read-only.
+.TP
+.B BASHPID
+Expands to the process ID of the current \fBbash\fP process.
+This differs from \fB$$\fP under certain circumstances, such as subshells
+that do not require \fBbash\fP to be re-initialized.
+Assignments to
+.SM
+.B BASHPID
+have no effect.
+If
+.B BASHPID
+is unset, it loses its special properties, even if it is
+subsequently reset.
+.TP
+.B BASH_ALIASES
+An associative array variable whose members correspond to the internal
+list of aliases as maintained by the \fBalias\fP builtin.
+Elements added to this array appear in the alias list; however,
+unsetting array elements currently does not cause aliases to be removed
+from the alias list.
+If
+.B BASH_ALIASES
+is unset, it loses its special properties, even if it is
+subsequently reset.
+.TP
+.B BASH_ARGC
+An array variable whose values are the number of parameters in each
+frame of the current \fBbash\fP execution call stack.
+The number of
+parameters to the current subroutine (shell function or script executed
+with \fB.\fP or \fBsource\fP) is at the top of the stack.
+When a subroutine is executed, the number of parameters passed is pushed onto
+.SM
+.BR BASH_ARGC .
+The shell sets
+.SM
+.B BASH_ARGC
+only when in extended debugging mode (see the description of the
+.B extdebug
+option to the
+.B shopt
+builtin below).
+Setting \fBextdebug\fP after the shell has started to execute a script,
+or referencing this variable when \fBextdebug\fP is not set,
+may result in inconsistent values.
+.TP
+.B BASH_ARGV
+An array variable containing all of the parameters in the current \fBbash\fP
+execution call stack.  The final parameter of the last subroutine call
+is at the top of the stack; the first parameter of the initial call is
+at the bottom.  When a subroutine is executed, the parameters supplied
+are pushed onto
+.SM
+.BR BASH_ARGV .
+The shell sets
+.SM
+.B BASH_ARGV
+only when in extended debugging mode
+(see the description of the
+.B extdebug
+option to the
+.B shopt
+builtin below).
+Setting \fBextdebug\fP after the shell has started to execute a script,
+or referencing this variable when \fBextdebug\fP is not set,
+may result in inconsistent values.
+.TP
+.B BASH_ARGV0
+When referenced, this variable expands to the name of the shell or shell
+script (identical to
+.BR $0 ;
+see the description of special parameter 0 above).
+Assignment to
+.B BASH_ARGV0
+causes the value assigned to also be assigned to \fB$0\fP.
+If
+.B BASH_ARGV0
+is unset, it loses its special properties, even if it is
+subsequently reset.
+.TP
+.B BASH_CMDS
+An associative array variable whose members correspond to the internal
+hash table of commands as maintained by the \fBhash\fP builtin.
+Elements added to this array appear in the hash table; however,
+unsetting array elements currently does not cause command names to be removed
+from the hash table.
+If
+.B BASH_CMDS
+is unset, it loses its special properties, even if it is
+subsequently reset.
+.TP
+.B BASH_COMMAND
+The command currently being executed or about to be executed, unless the
+shell is executing a command as the result of a trap,
+in which case it is the command executing at the time of the trap.
+If
+.B BASH_COMMAND
+is unset, it loses its special properties, even if it is
+subsequently reset.
+.TP
+.B BASH_EXECUTION_STRING
+The command argument to the \fB\-c\fP invocation option.
+.TP
+.B BASH_LINENO
+An array variable whose members are the line numbers in source files
+where each corresponding member of
+.SM
+.B FUNCNAME
+was invoked.
+\fB${BASH_LINENO[\fP\fI$i\fP\fB]}\fP is the line number in the source
+file (\fB${BASH_SOURCE[\fP\fI$i+1\fP\fB]}\fP) where
+\fB${FUNCNAME[\fP\fI$i\fP\fB]}\fP was called
+(or \fB${BASH_LINENO[\fP\fI$i-1\fP\fB]}\fP if referenced within another
+shell function).
+Use
+.SM
+.B LINENO
+to obtain the current line number.
+.TP
+.B BASH_LOADABLES_PATH
+A colon-separated list of directories in which the shell looks for
+dynamically loadable builtins specified by the
+.B enable
+command.
+.TP
+.B BASH_REMATCH
+An array variable whose members are assigned by the \fB=~\fP binary
+operator to the \fB[[\fP conditional command.
+The element with index 0 is the portion of the string
+matching the entire regular expression.
+The element with index \fIn\fP is the portion of the
+string matching the \fIn\fPth parenthesized subexpression.
+.TP
+.B BASH_SOURCE
+An array variable whose members are the source filenames
+where the corresponding shell function names in the
+.SM
+.B FUNCNAME
+array variable are defined.
+The shell function
+\fB${FUNCNAME[\fP\fI$i\fP\fB]}\fP is defined in the file
+\fB${BASH_SOURCE[\fP\fI$i\fP\fB]}\fP and called from
+\fB${BASH_SOURCE[\fP\fI$i+1\fP\fB]}\fP.
+.TP
+.B BASH_SUBSHELL
+Incremented by one within each subshell or subshell environment when
+the shell begins executing in that environment.
+The initial value is 0.
+If
+.B BASH_SUBSHELL
+is unset, it loses its special properties, even if it is
+subsequently reset.
+.TP
+.B BASH_VERSINFO
+A readonly array variable whose members hold version information for
+this instance of
+.BR bash .
+The values assigned to the array members are as follows:
+.sp .5
+.RS
+.TP 24
+.B BASH_VERSINFO[\fR0\fP]
+The major version number (the \fIrelease\fP).
+.TP
+.B BASH_VERSINFO[\fR1\fP]

+below).
+.TP
+.B COMP_POINT
+The index of the current cursor position relative to the beginning of
+the current command.
+If the current cursor position is at the end of the current command,
+the value of this variable is equal to \fB${#COMP_LINE}\fP.
+This variable is available only in shell functions and external
+commands invoked by the
+programmable completion facilities (see \fBProgrammable Completion\fP
+below).
+.TP
+.B COMP_TYPE
+Set to an integer value corresponding to the type of completion attempted
+that caused a completion function to be called:
+\fITAB\fP, for normal completion,
+\fI?\fP, for listing completions after successive tabs,
+\fI!\fP, for listing alternatives on partial word completion,
+\fI@\fP, to list completions if the word is not unmodified,
+or
+\fI%\fP, for menu completion.
+This variable is available only in shell functions and external
+commands invoked by the
+programmable completion facilities (see \fBProgrammable Completion\fP
+below).
+.TP
+.B COMP_WORDBREAKS
+The set of characters that the \fBreadline\fP library treats as word
+separators when performing word completion.
+If
+.SM
+.B COMP_WORDBREAKS
+is unset, it loses its special properties, even if it is
+subsequently reset.
+.TP
+.B COMP_WORDS
+An array variable (see \fBArrays\fP below) consisting of the individual
+words in the current command line.
+The line is split into words as \fBreadline\fP would split it, using
+.SM
+.B COMP_WORDBREAKS
+as described above.
+This variable is available only in shell functions invoked by the
+programmable completion facilities (see \fBProgrammable Completion\fP

+.TP
+.B COPROC
+An array variable (see \fBArrays\fP below) created to hold the file descriptors
+for output from and input to an unnamed coprocess (see \fBCoprocesses\fP
+above).
+.TP
+.B DIRSTACK
+An array variable (see
+.B Arrays
+below) containing the current contents of the directory stack.
+Directories appear in the stack in the order they are displayed by the
+.B dirs
+builtin.
+Assigning to members of this array variable may be used to modify
+directories already in the stack, but the
+.B pushd
+and
+.B popd
+builtins must be used to add and remove directories.
+Assignment to this variable will not change the current directory.
+If
+.SM
+.B DIRSTACK
+is unset, it loses its special properties, even if it is
+subsequently reset.
+.TP
+.B EPOCHREALTIME
+Each time this parameter is referenced, it expands to the number of seconds
+since the Unix Epoch (see \fItime\fP\fR(3)\fP) as a floating point value
+with micro-second granularity.
+Assignments to
+.SM
+.B EPOCHREALTIME
+are ignored.
+If

+.B EPOCHSECONDS
+is unset, it loses its special properties, even if it is
+subsequently reset.
+.TP
+.B EUID
+Expands to the effective user ID of the current user, initialized at
+shell startup.  This variable is readonly.
+.TP
+.B FUNCNAME
+An array variable containing the names of all shell functions
+currently in the execution call stack.
+The element with index 0 is the name of any currently-executing
+shell function.
+The bottom-most element (the one with the highest index) is
+.if t \f(CW"main"\fP.

+have no effect.
+If
+.SM
+.B FUNCNAME
+is unset, it loses its special properties, even if it is
+subsequently reset.
+.if t .sp 0.5
+.if n .sp 1
+This variable can be used with \fBBASH_LINENO\fP and \fBBASH_SOURCE\fP.
+Each element of \fBFUNCNAME\fP has corresponding elements in
+\fBBASH_LINENO\fP and \fBBASH_SOURCE\fP to describe the call stack.
+For instance, \fB${FUNCNAME[\fP\fI$i\fP\fB]}\fP was called from the file
+\fB${BASH_SOURCE[\fP\fI$i+1\fP\fB]}\fP at line number
+\fB${BASH_LINENO[\fP\fI$i\fP\fB]}\fP.
+The \fBcaller\fP builtin displays the current call stack using this
+information.
+.TP
+.B GROUPS
+An array variable containing the list of groups of which the current

+.TP
+.B HOSTNAME
+Automatically set to the name of the current host.
+.TP
+.B HOSTTYPE
+Automatically set to a string that uniquely
+describes the type of machine on which
+.B bash
+is executing.
+The default is system-dependent.
+.TP
+.B LINENO
+Each time this parameter is referenced, the shell substitutes
+a decimal number representing the current sequential line number
+(starting with 1) within a script or function.  When not in a
+script or function, the value substituted is not guaranteed to
+be meaningful.
+If
+.SM
+.B LINENO
+is unset, it loses its special properties, even if it is
+subsequently reset.
+.TP
+.B MACHTYPE
+Automatically set to a string that fully describes the system

+.SM
+.B SHELL BUILTIN COMMANDS
+below).
+.TP
+.B OPTIND
+The index of the next argument to be processed by the
+.B getopts
+builtin command (see
+.SM
+.B SHELL BUILTIN COMMANDS
+below).
+.TP
+.B OSTYPE
+Automatically set to a string that
+describes the operating system on which
+.B bash
+is executing.
+The default is system-dependent.
+.TP
+.B PIPESTATUS
+An array variable (see
+.B Arrays
+below) containing a list of exit status values from the processes
+in the most-recently-executed foreground pipeline (which may
+contain only a single command).
+.TP
+.B PPID
+The process ID of the shell's parent.  This variable is readonly.
+.TP
+.B PWD
+The current working directory as set by the
+.B cd
+command.
+.TP
+.B RANDOM
+Each time this parameter is referenced, it expands to a random integer
+between 0 and 32767.
+Assigning
+a value to
+.SM
+.BR RANDOM
+initializes (seeds) the sequence of random numbers.
+If
+.SM
+.B RANDOM
+is unset, it loses its special properties, even if it is
+subsequently reset.
+.TP
+.B READLINE_ARGUMENT
+Any numeric argument given to a readline command that was defined using
+.if t \f(CWbind -x\fP
+.if n "bind -x"
+(see
+.SM
+.B "SHELL BUILTIN COMMANDS"
+below)
+when it was invoked.
+.TP
+.B READLINE_LINE
+The contents of the
+.B readline
+line buffer, for use with
+.if t \f(CWbind -x\fP
+.if n "bind -x"
+(see
+.SM
+.B "SHELL BUILTIN COMMANDS"
+below).
+.TP
+.B READLINE_MARK
+The position of the mark (saved insertion point) in the
+.B readline
+line buffer, for use with
+.if t \f(CWbind -x\fP
+.if n "bind -x"
+(see
+.SM
+.B "SHELL BUILTIN COMMANDS"
+below).
+The characters between the insertion point and the mark are often
+called the \fIregion\fP.
+.TP
+.B READLINE_POINT
+The position of the insertion point in the
+.B readline
+line buffer, for use with
+.if t \f(CWbind -x\fP
+.if n "bind -x"
+(see
+.SM
+.B "SHELL BUILTIN COMMANDS"
+below).
+.TP
+.B REPLY
+Set to the line of input read by the
+.B read
+builtin command when no arguments are supplied.
+.TP
+.B SECONDS
+Each time this parameter is
+referenced, it expands to the number of seconds since shell invocation.
+If a value is assigned to
+.SM
+.BR SECONDS ,
+the value returned upon subsequent
+references is
+the number of seconds since the assignment plus the value assigned.
+The number of seconds at shell invocation and the current time are always
+determined by querying the system clock.
+If
+.SM
+.B SECONDS
+is unset, it loses its special properties, even if it is
+subsequently reset.
+.TP
+.B SHELLOPTS
+A colon-separated list of enabled shell options.  Each word in
+the list is a valid argument for the
+.B \-o
+option to the
+.B set
+builtin command (see
+.SM
+.B "SHELL BUILTIN COMMANDS"
+below).  The options appearing in
+.SM
+.B SHELLOPTS
+are those reported as
+.I on
+by \fBset \-o\fP.
+If this variable is in the environment when
+.B bash
+starts up, each shell option in the list will be enabled before
+reading any startup files.
+This variable is read-only.
+.TP
+.B SHLVL
+Incremented by one each time an instance of
+.B bash
+is started.
+.TP
+.B SRANDOM
+This variable expands to a 32-bit pseudo-random number each time it is
+referenced. The random number generator is not linear on systems that
+support \f(CW/dev/urandom\fP or \fIarc4random\fP, so each returned number
+has no relationship to the numbers preceding it.
+The random number generator cannot be seeded, so assignments to this
+variable have no effect.
+If
+.SM
+.B SRANDOM
+is unset, it loses its special properties,
+even if it is subsequently reset.
+.TP
+.B UID
+Expands to the user ID of the current user, initialized at shell startup.
+This variable is readonly.
+.PD
+.PP
+The following variables are used by the shell.  In some cases,
+.B bash
+assigns a default value to a variable; these cases are noted
+below.
+.PP
+.PD 0
+.TP
+.B BASH_COMPAT
+The value is used to set the shell's compatibility level.
+See
+.SM
+.B "SHELL COMPATIBILITY MODE"
+below for a description of the various compatibility
+levels and their effects.
+The value may be a decimal number (e.g., 4.2) or an integer (e.g., 42)
+corresponding to the desired compatibility level.
+If \fBBASH_COMPAT\fP is unset or set to the empty string, the compatibility
+level is set to the default for the current version.
+If \fBBASH_COMPAT\fP is set to a value that is not one of the valid
+compatibility levels, the shell prints an error message and sets the
+compatibility level to the default for the current version.
+The valid values correspond to the compatibility levels
+described below under
+.SM
+.BR "SHELL COMPATIBILITY MODE" .
+For example, 4.2 and 42 are valid values that correspond
+to the \fBcompat42\fP \fBshopt\fP option
+and set the compatibility level to 42.
+The current version is also a valid value.
+.TP
+.B BASH_ENV
+If this parameter is set when \fBbash\fP is executing a shell script,
+its value is interpreted as a filename containing commands to
+initialize the shell, as in
+.IR ~/.bashrc .
+The value of
+.SM
+.B BASH_ENV
+is subjected to parameter expansion, command substitution, and arithmetic
+expansion before being interpreted as a filename.
+.SM
+.B PATH
+is not used to search for the resultant filename.
+.TP
+.B BASH_XTRACEFD
+If set to an integer corresponding to a valid file descriptor, \fBbash\fP
+will write the trace output generated when
+.if t \f(CWset -x\fP
+.if n \fIset -x\fP
+is enabled to that file descriptor.
+The file descriptor is closed when
+.SM
+.B BASH_XTRACEFD
+is unset or assigned a new value.
+Unsetting
+.SM
+.B BASH_XTRACEFD
+or assigning it the empty string causes the
+trace output to be sent to the standard error.
+Note that setting
+.SM
+.B BASH_XTRACEFD
+to 2 (the standard error file
+descriptor) and then unsetting it will result in the standard error
+being closed.
+.TP
+.B CDPATH
+The search path for the
+.B cd
+command.
+This is a colon-separated list of directories in which the shell looks
+for destination directories specified by the
+.B cd
+command.
+A sample value is
+.if t \f(CW".:~:/usr"\fP.
+.if n ".:~:/usr".
+.TP
+.B CHILD_MAX
+Set the number of exited child status values for the shell to remember.
+Bash will not allow this value to be decreased below a POSIX-mandated
+minimum, and there is a maximum value (currently 8192) that this may
+not exceed.
+The minimum value is system-dependent.
+.TP
+.B COLUMNS
+Used by the \fBselect\fP compound command to determine the terminal width
+when printing selection lists.
+Automatically set if the
+.B checkwinsize
+option is enabled or in an interactive shell upon receipt of a
+.SM
+.BR SIGWINCH .
+.TP
+.B COMPREPLY
+An array variable from which \fBbash\fP reads the possible completions
+generated by a shell function invoked by the programmable completion
+facility (see \fBProgrammable Completion\fP below).
+Each array element contains one possible completion.
+.TP
+.B EMACS
+If \fBbash\fP finds this variable in the environment when the shell starts
+with value
+.if t \f(CWt\fP,
+.if n "t",
+it assumes that the shell is running in an Emacs shell buffer and disables
+line editing.
+.TP
+.B ENV
+Expanded and executed similarly to
+.SM
+.B BASH_ENV
+(see \fBINVOCATION\fP above)
+when an interactive shell is invoked in \fIposix mode\fP.
+.TP
+.B EXECIGNORE
+A colon-separated list of shell patterns (see \fBPattern Matching\fP)
+defining the list of filenames to be ignored by command search using
+\fBPATH\fP.
+Files whose full pathnames match one of these patterns are not considered
+executable files for the purposes of completion and command execution
+via \fBPATH\fP lookup.
+This does not affect the behavior of the \fB[\fP, \fBtest\fP, and \fB[[\fP
+commands.
+Full pathnames in the command hash table are not subject to \fBEXECIGNORE\fP.
+Use this variable to ignore shared library files that have the executable
+bit set, but are not executable files.
+The pattern matching honors the setting of the \fBextglob\fP shell
+option.
+.TP
+.B FCEDIT
+The default editor for the
+.B fc
+builtin command.
+.TP
+.B FIGNORE
+A colon-separated list of suffixes to ignore when performing
+filename completion (see
+.SM
+.B READLINE
+below).
+A filename whose suffix matches one of the entries in
+.SM
+.B FIGNORE
+is excluded from the list of matched filenames.
+A sample value is
+.if t \f(CW".o:~"\fP.
+.if n ".o:~".
+.TP
+.B FUNCNEST
+If set to a numeric value greater than 0, defines a maximum function
+nesting level.  Function invocations that exceed this nesting level
+will cause the current command to abort.
+.TP
+.B GLOBIGNORE
+A colon-separated list of patterns defining the set of file names to
+be ignored by pathname expansion.
+If a file name matched by a pathname expansion pattern also matches one
+of the patterns in
+.SM
+.BR GLOBIGNORE ,
+it is removed from the list of matches.
+.TP
+.B HISTCONTROL
+A colon-separated list of values controlling how commands are saved on
+the history list.
+If the list of values includes
+.IR ignorespace ,
+lines which begin with a
+.B space
+character are not saved in the history list.
+A value of
+.I ignoredups
+causes lines matching the previous history entry to not be saved.
+A value of
+.I ignoreboth
+is shorthand for \fIignorespace\fP and \fIignoredups\fP.
+A value of
+.I erasedups
+causes all previous lines matching the current line to be removed from
+the history list before that line is saved.
+Any value not in the above list is ignored.
+If
+.SM
+.B HISTCONTROL
+is unset, or does not include a valid value,
+all lines read by the shell parser are saved on the history list,
+subject to the value of
+.SM
+.BR HISTIGNORE .
+The second and subsequent lines of a multi-line compound command are
+not tested, and are added to the history regardless of the value of
+.SM
+.BR HISTCONTROL .
+.TP
+.B HISTFILE
+The name of the file in which command history is saved (see
+.SM
+.B HISTORY
+below).  The default value is \fI~/.bash_history\fP.  If unset, the
+command history is not saved when a shell exits.
+.TP
+.B HISTFILESIZE
+The maximum number of lines contained in the history file.  When this
+variable is assigned a value, the history file is truncated, if
+necessary,
+to contain no more than that number of lines by removing the oldest entries.
+The history file is also truncated to this size after
+writing it when a shell exits.
+If the value is 0, the history file is truncated to zero size.
+Non-numeric values and numeric values less than zero inhibit truncation.
+The shell sets the default value to the value of \fBHISTSIZE\fP
+after reading any startup files.
+.TP
+.B HISTIGNORE
+A colon-separated list of patterns used to decide which command lines
+should be saved on the history list.  Each pattern is anchored at the
+beginning of the line and must match the complete line (no implicit
+`\fB*\fP' is appended).  Each pattern is tested against the line
+after the checks specified by
+.SM
+.B HISTCONTROL
+are applied.
+In addition to the normal shell pattern matching characters, `\fB&\fP'
+matches the previous history line.  `\fB&\fP' may be escaped using a
+backslash; the backslash is removed before attempting a match.
+The second and subsequent lines of a multi-line compound command are
+not tested, and are added to the history regardless of the value of
+.SM
+.BR HISTIGNORE .
+The pattern matching honors the setting of the \fBextglob\fP shell
+option.
+.TP
+.B HISTSIZE
+The number of commands to remember in the command history (see
+.SM
+.B HISTORY
+below).
+If the value is 0, commands are not saved in the history list.
+Numeric values less than zero result in every command being saved
+on the history list (there is no limit).
+The shell sets the default value to 500 after reading any startup files.
+.TP
+.B HISTTIMEFORMAT
+If this variable is set and not null, its value is used as a format string
+for \fIstrftime\fP(3) to print the time stamp associated with each history
+entry displayed by the \fBhistory\fP builtin.
+If this variable is set, time stamps are written to the history file so
+they may be preserved across shell sessions.
+This uses the history comment character to distinguish timestamps from
+other history lines.
+.TP
+.B HOME
+The home directory of the current user; the default argument for the
+\fBcd\fP builtin command.
+The value of this variable is also used when performing tilde expansion.
+.TP
+.B HOSTFILE
+Contains the name of a file in the same format as
+.FN /etc/hosts
+that should be read when the shell needs to complete a
+hostname.
+The list of possible hostname completions may be changed while the
+shell is running;
+the next time hostname completion is attempted after the
+value is changed,
+.B bash
+adds the contents of the new file to the existing list.
+If
+.SM
+.B HOSTFILE
+is set, but has no value, or does not name a readable file,
+\fBbash\fP attempts to read
+.FN /etc/hosts
+to obtain the list of possible hostname completions.
+When
+.SM
+.B HOSTFILE
+is unset, the hostname list is cleared.
+.TP
+.B IFS
+The
+.I Internal Field Separator
+that is used
+for word splitting after expansion and to
+split lines into words with the
+.B read
+builtin command.  The default value is
+``<space><tab><newline>''.
+.TP
+.B IGNOREEOF
+Controls the
+action of an interactive shell on receipt of an
+.SM
+.B EOF
+character as the sole input.  If set, the value is the number of
+consecutive
+.SM
+.B EOF
+characters which must be
+typed as the first characters on an input line before
+.B bash
+exits.  If the variable exists but does not have a numeric value, or
+has no value, the default value is 10.  If it does not exist,
+.SM
+.B EOF
+signifies the end of input to the shell.
+.TP
+.B INPUTRC
+The filename for the
+.B readline
+startup file, overriding the default of
+.FN ~/.inputrc
+(see
+.SM
+.B READLINE
+below).
+.TP
+.B INSIDE_EMACS
+If this variable appears in the environment when the shell starts,
+\fBbash\fP assumes that it is running inside an Emacs shell buffer
+and may disable line editing, depending on the value of \fBTERM\fP.
+.TP
+.B LANG
+Used to determine the locale category for any category not specifically
+selected with a variable starting with \fBLC_\fP.
+.TP
+.B LC_ALL
+This variable overrides the value of
+.SM
+.B LANG
+and any other
+\fBLC_\fP variable specifying a locale category.
+.TP
+.B LC_COLLATE
+This variable determines the collation order used when sorting the
+results of pathname expansion, and determines the behavior of range
+expressions, equivalence classes, and collating sequences within
+pathname expansion and pattern matching.
+.TP
+.B LC_CTYPE
+This variable determines the interpretation of characters and the
+behavior of character classes within pathname expansion and pattern
+matching.
+.TP
+.B LC_MESSAGES
+This variable determines the locale used to translate double-quoted
+strings preceded by a \fB$\fP.
+.TP
+.B LC_NUMERIC
+This variable determines the locale category used for number formatting.
+.TP
+.B LC_TIME
+This variable determines the locale category used for data and time
+formatting.
+.TP
+.B LINES
+Used by the \fBselect\fP compound command to determine the column length
+for printing selection lists.
+Automatically set if the
+.B checkwinsize
+option is enabled or in an interactive shell upon receipt of a
+.SM
+.BR SIGWINCH .
+.TP
+.B MAIL
+If this parameter is set to a file or directory name and the
+.SM
+.B MAILPATH
+variable is not set,
+.B bash
+informs the user of the arrival of mail in the specified file or
+Maildir-format directory.
+.TP
+.B MAILCHECK
+Specifies how
+often (in seconds)
+.B bash
+checks for mail.  The default is 60 seconds.  When it is time to check
+for mail, the shell does so before displaying the primary prompt.
+If this variable is unset, or set to a value that is not a number
+greater than or equal to zero, the shell disables mail checking.
+.TP
+.B MAILPATH
+A colon-separated list of filenames to be checked for mail.
+The message to be printed when mail arrives in a particular file
+may be specified by separating the filename from the message with a `?'.
+When used in the text of the message, \fB$_\fP expands to the name of
+the current mailfile.
+Example:
+.RS
+.PP
+\fBMAILPATH\fP=\(aq/var/mail/bfox?"You have mail":~/shell\-mail?"$_ has mail!"\(aq
+.PP
+.B Bash
+can be configured to supply
+a default value for this variable (there is no value by default),
+but the location of the user
+mail files that it uses is system dependent (e.g., /var/mail/\fB$USER\fP).
+.RE
+.TP
+.B OPTERR
+If set to the value 1,
+.B bash
+displays error messages generated by the
+.B getopts
+builtin command (see
+.SM
+.B SHELL BUILTIN COMMANDS
+below).
+.SM
+.B OPTERR
+is initialized to 1 each time the shell is invoked or a shell
+script is executed.
+.TP
+.B PATH
+The search path for commands.  It
+is a colon-separated list of directories in which
+the shell looks for commands (see
+.SM
+.B COMMAND EXECUTION
+below).
+A zero-length (null) directory name in the value of
+.SM
+.B PATH
+indicates the current directory.
+A null directory name may appear as two adjacent colons, or as an initial
+or trailing colon.
+The default path is system-dependent,
+and is set by the administrator who installs
+.BR bash .
+A common value is
+.na
+.if t \f(CW/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin\fP.
+.if n ``/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin''.
+.ad
+.TP
+.B POSIXLY_CORRECT
+If this variable is in the environment when \fBbash\fP starts, the shell
+enters \fIposix mode\fP before reading the startup files, as if the
+.B \-\-posix
+invocation option had been supplied.  If it is set while the shell is
+running, \fBbash\fP enables \fIposix mode\fP, as if the command
+.if t \f(CWset -o posix\fP
+.if n \fIset -o posix\fP
+had been executed.
+When the shell enters \fIposix mode\fP, it sets this variable if it was
+not already set.
+.TP
+.B PROMPT_COMMAND
+If this variable is set, and is an array,
+the value of each set element is executed as a command
+prior to issuing each primary prompt.
+If this is set but not an array variable, 
+its value is used as a command to execute instead.
+.TP
+.B PROMPT_DIRTRIM
+If set to a number greater than zero, the value is used as the number of
+trailing directory components to retain when expanding the \fB\ew\fP and
+\fB\eW\fP prompt string escapes (see
+.SM
+.B PROMPTING
+below).  Characters removed are replaced with an ellipsis.
+.TP
+.B PS0
+The value of this parameter is expanded (see
+.SM
+.B PROMPTING
+below) and displayed by interactive shells after reading a command
+and before the command is executed.
+.TP
+.B PS1
+The value of this parameter is expanded (see
+.SM
+.B PROMPTING
+below) and used as the primary prompt string.  The default value is
+``\fB\es\-\ev\e$ \fP''.
+.TP
+.B PS2
+The value of this parameter is expanded as with
+.SM
+.B PS1
+and used as the secondary prompt string.  The default is
+``\fB> \fP''.
+.TP
+.B PS3
+The value of this parameter is used as the prompt for the
+.B select
+command (see
+.SM
+.B SHELL GRAMMAR
+above).
+.TP
+.B PS4
+The value of this parameter is expanded as with
+.SM
+.B PS1
+and the value is printed before each command
+.B bash
+displays during an execution trace.  The first character of
+the expanded value of
+.SM
+.B PS4
+is replicated multiple times, as necessary, to indicate multiple
+levels of indirection.  The default is ``\fB+ \fP''.
+.TP
+.B SHELL
+This variable expands to the full pathname to the shell.
+If it is not set when the shell starts,
+.B bash
+assigns to it the full pathname of the current user's login shell.
+.TP
+.B TIMEFORMAT
+The value of this parameter is used as a format string specifying
+how the timing information for pipelines prefixed with the
+.B time
+reserved word should be displayed.
+The \fB%\fP character introduces an escape sequence that is
+expanded to a time value or other information.
+The escape sequences and their meanings are as follows; the
+braces denote optional portions.
+.sp .5
+.RS
+.PD 0
+.TP 10
+.B %%
+A literal \fB%\fP.
+.TP
+.B %[\fIp\fP][l]R
+The elapsed time in seconds.
+.TP
+.B %[\fIp\fP][l]U
+The number of CPU seconds spent in user mode.
+.TP
+.B %[\fIp\fP][l]S
+The number of CPU seconds spent in system mode.
+.TP
+.B %P
+The CPU percentage, computed as (%U + %S) / %R.
+.PD
+.RE
+.IP
+The optional \fIp\fP is a digit specifying the \fIprecision\fP,
+the number of fractional digits after a decimal point.
+A value of 0 causes no decimal point or fraction to be output.
+At most three places after the decimal point may be specified;
+values of \fIp\fP greater than 3 are changed to 3.
+If \fIp\fP is not specified, the value 3 is used.
+.IP
+The optional \fBl\fP specifies a longer format, including
+minutes, of the form \fIMM\fPm\fISS\fP.\fIFF\fPs.
+The value of \fIp\fP determines whether or not the fraction is
+included.
+.IP
+If this variable is not set, \fBbash\fP acts as if it had the
+value \fB$\(aq\enreal\et%3lR\enuser\et%3lU\ensys\et%3lS\(aq\fP.
+If the value is null, no timing information is displayed.
+A trailing newline is added when the format string is displayed.
+.PD 0
+.TP
+.B TMOUT
+If set to a value greater than zero,
+.SM
+.B TMOUT
+is treated as the
+default timeout for the \fBread\fP builtin.
+The \fBselect\fP command terminates if input does not arrive
+after
+.SM
+.B TMOUT
+seconds when input is coming from a terminal.
+In an interactive shell, the value is interpreted as the
+number of seconds to wait for a line of input after issuing the
+primary prompt.
+.B Bash
+terminates after waiting for that number of seconds if a complete
+line of input does not arrive.
+.TP
+.B TMPDIR
+If set, \fBbash\fP uses its value as the name of a directory in which
+\fBbash\fP creates temporary files for the shell's use.
+.TP
+.B auto_resume
+This variable controls how the shell interacts with the user and
+job control.  If this variable is set, single word simple
+commands without redirections are treated as candidates for resumption
+of an existing stopped job.  There is no ambiguity allowed; if there is
+more than one job beginning with the string typed, the job most recently
+accessed is selected.  The
+.I name
+of a stopped job, in this context, is the command line used to
+start it.
+If set to the value
+.IR exact ,
+the string supplied must match the name of a stopped job exactly;
+if set to
+.IR substring ,
+the string supplied needs to match a substring of the name of a
+stopped job.  The
+.I substring
+value provides functionality analogous to the
+.B %?
+job identifier (see
+.SM
+.B JOB CONTROL
+below).  If set to any other value, the supplied string must
+be a prefix of a stopped job's name; this provides functionality
+analogous to the \fB%\fP\fIstring\fP job identifier.
+.TP
+.B histchars
+The two or three characters which control history expansion
+and tokenization (see
+.SM
+.B HISTORY EXPANSION
+below).  The first character is the \fIhistory expansion\fP character,
+the character which signals the start of a history
+expansion, normally `\fB!\fP'.
+The second character is the \fIquick substitution\fP
+character, which is used as shorthand for re-running the previous
+command entered, substituting one string for another in the command.
+The default is `\fB^\fP'.
+The optional third character is the character
+which indicates that the remainder of the line is a comment when found
+as the first character of a word, normally `\fB#\fP'.  The history
+comment character causes history substitution to be skipped for the
+remaining words on the line.  It does not necessarily cause the shell
+parser to treat the rest of the line as a comment.
+.PD
+.SS Arrays
+.B Bash
+provides one-dimensional indexed and associative array variables.
+Any variable may be used as an indexed array; the
+.B declare
+builtin will explicitly declare an array.
+There is no maximum
+limit on the size of an array, nor any requirement that members
+be indexed or assigned contiguously.
+Indexed arrays are referenced using integers (including arithmetic
+expressions) and are zero-based; associative arrays are referenced
+using arbitrary strings.
+Unless otherwise noted, indexed array indices must be non-negative integers.
+.PP
+An indexed array is created automatically if any variable is assigned to
+using the syntax \fIname\fP[\fIsubscript\fP]=\fIvalue\fP.  The
+.I subscript
+is treated as an arithmetic expression that must evaluate to a number.
+To explicitly declare an indexed array, use
+.B declare \-a \fIname\fP
+(see
+.SM
+.B SHELL BUILTIN COMMANDS
+below).
+.B declare \-a \fIname\fP[\fIsubscript\fP]
+is also accepted; the \fIsubscript\fP is ignored.
+.PP
+Associative arrays are created using
+.BR "declare \-A \fIname\fP" .
+.PP
+Attributes may be
+specified for an array variable using the
+.B declare
+and
+.B readonly
+builtins.  Each attribute applies to all members of an array.
+.PP
+Arrays are assigned to using compound assignments of the form
+\fIname\fP=\fB(\fPvalue\fI1\fP ... value\fIn\fP\fB)\fP, where each
+\fIvalue\fP may be of the form [\fIsubscript\fP]=\fIstring\fP.
+Indexed array assignments do not require anything but \fIstring\fP.
+Each \fIvalue\fP in the list is expanded using all the shell expansions
+described below under
+.SM
+.BR EXPANSION .
+When assigning to indexed arrays, if the optional brackets and subscript
+are supplied, that index is assigned to;
+otherwise the index of the element assigned is the last index assigned
+to by the statement plus one.  Indexing starts at zero.
+.PP
+When assigning to an associative array, the words in a compound assignment
+may be either assignment statements, for which the subscript is required,
+or a list of words that is interpreted as a sequence of alternating keys
+and values:
+\fIname\fP=\fB( \fP\fIkey1 value1 key2 value2\fP ...\fB)\fP.
+These are treated identically to
+\fIname\fP=\fB(\fP [\fIkey1\fP]=\fIvalue1\fP [\fIkey2\fP]=\fIvalue2\fP ...\fB)\fP.
+The first word in the list determines how the remaining words
+are interpreted; all assignments in a list must be of the same type.
+When using key/value pairs, the keys may not be missing or empty;
+a final missing value is treated like the empty string.
+.PP
+This syntax is also accepted by the
+.B declare
+builtin.  Individual array elements may be assigned to using the
+\fIname\fP[\fIsubscript\fP]=\fIvalue\fP syntax introduced above.
+When assigning to an indexed array, if
+.I name
+is subscripted by a negative number, that number is
+interpreted as relative to one greater than the maximum index of
+\fIname\fP, so negative indices count back from the end of the
+array, and an index of \-1 references the last element.
+.PP
+The += operator will append to an array variable when assigning
+using the compound assignment syntax; see
+.SM
+.B PARAMETERS
+above.
+.PP
+Any element of an array may be referenced using
+${\fIname\fP[\fIsubscript\fP]}.  The braces are required to avoid
+conflicts with pathname expansion.  If
+\fIsubscript\fP is \fB@\fP or \fB*\fP, the word expands to
+all members of \fIname\fP.  These subscripts differ only when the
+word appears within double quotes.  If the word is double-quoted,
+${\fIname\fP[*]} expands to a single
+word with the value of each array member separated by the first
+character of the
+.SM
+.B IFS
+special variable, and ${\fIname\fP[@]} expands each element of
+\fIname\fP to a separate word.  When there are no array members,
+${\fIname\fP[@]} expands to nothing.
+If the double-quoted expansion occurs within a word, the expansion of
+the first parameter is joined with the beginning part of the original
+word, and the expansion of the last parameter is joined with the last
+part of the original word.
+This is analogous to the expansion
+of the special parameters \fB*\fP and \fB@\fP (see
+.B Special Parameters
+above).  ${#\fIname\fP[\fIsubscript\fP]} expands to the length of
+${\fIname\fP[\fIsubscript\fP]}.  If \fIsubscript\fP is \fB*\fP or
+\fB@\fP, the expansion is the number of elements in the array.
+If the
+.I subscript
+used to reference an element of an indexed array
+evaluates to a number less than zero, it is
+interpreted as relative to one greater than the maximum index of the array,
+so negative indices count back from the end of the
+array, and an index of \-1 references the last element.
+.PP
+Referencing an array variable without a subscript is equivalent to
+referencing the array with a subscript of 0.
+Any reference to a variable using a valid subscript is legal, and
+.B bash
+will create an array if necessary.
+.PP
+An array variable is considered set if a subscript has been assigned a
+value.  The null string is a valid value.
+.PP
+It is possible to obtain the keys (indices) of an array as well as the values.
+${\fB!\fP\fIname\fP[\fI@\fP]} and ${\fB!\fP\fIname\fP[\fI*\fP]}
+expand to the indices assigned in array variable \fIname\fP.
+The treatment when in double quotes is similar to the expansion of the
+special parameters \fI@\fP and \fI*\fP within double quotes.
+.PP
+The
+.B unset
+builtin is used to destroy arrays.  \fBunset\fP \fIname\fP[\fIsubscript\fP]
+destroys the array element at index \fIsubscript\fP,
+for both indexed and associative arrays.
+Negative subscripts to indexed arrays are interpreted as described above.
+Unsetting the last element of an array variable does not unset the variable.
+\fBunset\fP \fIname\fP, where \fIname\fP is an array,
+removes the entire array.
+\fBunset\fP \fIname\fP[\fIsubscript\fP], where
+\fIsubscript\fP is \fB*\fP or \fB@\fP, behaves differently depending on
+whether \fIname\fP is an indexed or associative array.
+If \fIname\fP is an associative array, this unsets the element with
+subscript \fB*\fP or \fB@\fP.
+If \fIname\fP is an indexed array, unset removes all of the elements but
+does not remove the array itself.
+.PP
+When using a variable name with a subscript as an argument to a command,
+such as with \fBunset\fP, without using the word expansion syntax
+described above, the argument is subject to pathname expansion.
+If pathname expansion is not desired, the argument should be quoted.
+.PP
+The
+.BR declare ,
+.BR local ,
+and
+.B readonly
+builtins each accept a
+.B \-a
+option to specify an indexed array and a
+.B \-A
+option to specify an associative array.
+If both options are supplied,
+.B \-A
+takes precedence.
+The
+.B read
+builtin accepts a

+to an array.  The
+.B set

+.B declare
+builtins display array values in a way that allows them to be
+reused as assignments.
+.SH EXPANSION
+Expansion is performed on the command line after it has been split into
+words.  There are seven kinds of expansion performed:
+.IR "brace expansion" ,
+.IR "tilde expansion" ,
+.IR "parameter and variable expansion" ,
+.IR "command substitution" ,
+.IR "arithmetic expansion" ,
+.IR "word splitting" ,
+and
+.IR "pathname expansion" .
+.PP
+The order of expansions is:
+brace expansion;
+tilde expansion, parameter and variable expansion, arithmetic expansion,
+and command substitution (done in a left-to-right fashion);
+word splitting;
+and pathname expansion.
+.PP
+On systems that can support it, there is an additional expansion
+available: \fIprocess substitution\fP.
+This is performed at the
+same time as tilde, parameter, variable, and arithmetic expansion and
+command substitution.
+.PP
+After these expansions are performed, quote characters present in the
+original word are removed unless they have been quoted themselves
+(\fIquote removal\fP).
+.PP
+Only brace expansion, word splitting, and pathname expansion
+can increase the number of words of the expansion; other expansions
+expand a single word to a single word.
+The only exceptions to this are the expansions of
+"\fB$@\fP" and "\fB${\fP\fIname\fP\fB[@]}\fP",
+and, in most cases, \fB$*\fP and \fB${\fP\fIname\fP\fB[*]}\fP
+as explained above (see
+.SM
+.BR PARAMETERS ).
+.SS Brace Expansion
+.I "Brace expansion"
+is a mechanism by which arbitrary strings
+may be generated.  This mechanism is similar to
+\fIpathname expansion\fP, but the filenames generated
+need not exist.  Patterns to be brace expanded take
+the form of an optional
+.IR preamble ,
+followed by either a series of comma-separated strings or
+a sequence expression between a pair of braces, followed by
+an optional
+.IR postscript .
+The preamble is prefixed to each string contained
+within the braces, and the postscript is then appended
+to each resulting string, expanding left to right.
+.PP
+Brace expansions may be nested.  The results of each expanded
+string are not sorted; left to right order is preserved.
+For example, a\fB{\fPd,c,b\fB}\fPe expands into `ade ace abe'.
+.PP
+A sequence expression takes the form
+\fB{\fP\fIx\fP\fB..\fP\fIy\fP\fB[..\fP\fIincr\fP\fB]}\fP,
+where \fIx\fP and \fIy\fP are either integers or single letters,
+and \fIincr\fP, an optional increment, is an integer.
+When integers are supplied, the expression expands to each number between
+\fIx\fP and \fIy\fP, inclusive.
+Supplied integers may be prefixed with \fI0\fP to force each term to have the
+same width.
+When either \fIx\fP or \fPy\fP begins with a zero, the shell
+attempts to force all generated terms to contain the same number of digits,
+zero-padding where necessary.
+When letters are supplied, the expression expands to each character
+lexicographically between \fIx\fP and \fIy\fP, inclusive,
+using the default C locale.
+Note that both \fIx\fP and \fIy\fP must be of the same type
+(integer or letter).
+When the increment is supplied, it is used as the difference between
+each term.  The default increment is 1 or \-1 as appropriate.
+.PP
+Brace expansion is performed before any other expansions,
+and any characters special to other expansions are preserved
+in the result.  It is strictly textual.
+.B Bash
+does not apply any syntactic interpretation to the context of the
+expansion or the text between the braces.
+.PP
+A correctly-formed brace expansion must contain unquoted opening
+and closing braces, and at least one unquoted comma or a valid
+sequence expression.
+Any incorrectly formed brace expansion is left unchanged.
+A \fB{\fP or \fB,\fP may be quoted with a backslash to prevent its
+being considered part of a brace expression.
+To avoid conflicts with parameter expansion, the string \fB${\fP
+is not considered eligible for brace expansion, and inhibits brace
+expansion until the closing \fB}\fP.
+.PP
+This construct is typically used as shorthand when the common
+prefix of the strings to be generated is longer than in the
+above example:
+.RS
+.PP
+mkdir /usr/local/src/bash/{old,new,dist,bugs}
+.RE
+or
+.RS
+chown root /usr/{ucb/{ex,edit},lib/{ex?.?*,how_ex}}
+.RE
+.PP
+Brace expansion introduces a slight incompatibility with
+historical versions of
+.BR sh .
+.B sh
+does not treat opening or closing braces specially when they
+appear as part of a word, and preserves them in the output.
+.B Bash
+removes braces from words as a consequence of brace
+expansion.  For example, a word entered to
+.B sh
+as \fIfile{1,2}\fP
+appears identically in the output.  The same word is
+output as
+.I file1 file2
+after expansion by
+.BR bash .
+If strict compatibility with
+.B sh
+is desired, start
+.B bash
+with the
+.B +B
+option or disable brace expansion with the
+.B +B
+option to the
+.B set
+command (see
+.SM
+.B SHELL BUILTIN COMMANDS
+below).
+.SS Tilde Expansion
+If a word begins with an unquoted tilde character (`\fB~\fP'), all of
+the characters preceding the first unquoted slash (or all characters,
+if there is no unquoted slash) are considered a \fItilde-prefix\fP.
+If none of the characters in the tilde-prefix are quoted, the
+characters in the tilde-prefix following the tilde are treated as a
+possible \fIlogin name\fP.
+If this login name is the null string, the tilde is replaced with the
+value of the shell parameter
+.SM
+.BR HOME .
+If
+.SM
+.B HOME
+is unset, the home directory of the user executing the shell is
+substituted instead.
+Otherwise, the tilde-prefix is replaced with the home directory
+associated with the specified login name.
+.PP
+If the tilde-prefix is a `~+', the value of the shell variable
+.SM
+.B PWD
+replaces the tilde-prefix.
+If the tilde-prefix is a `~\-', the value of the shell variable
+.SM
+.BR OLDPWD ,
+if it is set, is substituted.
+If the characters following the tilde in the tilde-prefix consist
+of a number \fIN\fP, optionally prefixed
+by a `+' or a `\-', the tilde-prefix is replaced with the corresponding
+element from the directory stack, as it would be displayed by the
+.B dirs
+builtin invoked with the tilde-prefix as an argument.
+If the characters following the tilde in the tilde-prefix consist of a
+number without a leading `+' or `\-', `+' is assumed.
+.PP
+If the login name is invalid, or the tilde expansion fails, the word
+is unchanged.
+.PP
+Each variable assignment is checked for unquoted tilde-prefixes immediately
+following a
+.B :
+or the first
+.BR = .
+In these cases, tilde expansion is also performed.
+Consequently, one may use filenames with tildes in assignments to
+.SM
+.BR PATH ,
+.SM
+.BR MAILPATH ,
+and
+.SM
+.BR CDPATH ,
+and the shell assigns the expanded value.
+.PP
+Bash also performs tilde expansion on words satisfying the conditions of
+variable assignments (as described above under
+.SM
+.BR PARAMETERS )
+when they appear as arguments to simple commands.
+Bash does not do this, except for the \fIdeclaration\fP commands listed
+above, when in \fIposix mode\fP.
+.SS Parameter Expansion
+The `\fB$\fP' character introduces parameter expansion,
+command substitution, or arithmetic expansion.  The parameter name
+or symbol to be expanded may be enclosed in braces, which
+are optional but serve to protect the variable to be expanded from
+characters immediately following it which could be
+interpreted as part of the name.
+.PP
+When braces are used, the matching ending brace is the first `\fB}\fP'
+not escaped by a backslash or within a quoted string, and not within an
+embedded arithmetic expansion, command substitution, or parameter
+expansion.
+.PP
+.PD 0
+.TP
+${\fIparameter\fP}
+The value of \fIparameter\fP is substituted.  The braces are required
+when
+.I parameter
+is a positional parameter with more than one digit,
+or when
+.I parameter
+is followed by a character which is not to be
+interpreted as part of its name.
+The \fIparameter\fP is a shell parameter as described above
+\fBPARAMETERS\fP) or an array reference (\fBArrays\fP).
+.PD
+.PP
+If the first character of \fIparameter\fP is an exclamation point (\fB!\fP),
+and \fIparameter\fP is not a \fInameref\fP,
+it introduces a level of indirection.
+\fBBash\fP uses the value formed by expanding the rest of
+\fIparameter\fP as the new \fIparameter\fP; this is then
+expanded and that value is used in the rest of the expansion, rather
+than the expansion of the original \fIparameter\fP.
+This is known as \fIindirect expansion\fP.
+The value is subject to tilde expansion,
+parameter expansion, command substitution, and arithmetic expansion.
+If \fIparameter\fP is a nameref, this expands to the name of the
+parameter referenced by \fIparameter\fP instead of performing the
+complete indirect expansion.
+The exceptions to this are the expansions of ${\fB!\fP\fIprefix\fP\fB*\fP} and
+${\fB!\fP\fIname\fP[\fI@\fP]} described below.
+The exclamation point must immediately follow the left brace in order to
+introduce indirection.

+In each of the cases below, \fIword\fP is subject to tilde expansion,
+parameter expansion, command substitution, and arithmetic expansion.
+.PP
+When not performing substring expansion, using the forms documented below

+\fB$(\fP\fIcommand\fP\|\fB)\fP
+.RE
+or
+.RS
+\fB\`\fP\fIcommand\fP\fB\`\fP

+.PP
+When the old-style backquote form of substitution is used,
+backslash retains its literal meaning except when followed by
+.BR $ ,
+.BR \` ,

+.BR \e .
+The first backquote not preceded by a backslash terminates the
+command substitution.

+\fIProcess substitution\fP allows a process's input or output to be
+referred to using a filename.
+It takes the form of
+\fB<(\fP\fIlist\^\fP\fB)\fP
+or
+\fB>(\fP\fIlist\^\fP\fB)\fP.
+The process \fIlist\fP is run asynchronously, and its input or output
+appears as a filename.

+the file will provide input for \fIlist\fP.  If the
+\fB<(\fP\fIlist\^\fP\fB)\fP form is used, the file passed as an
+argument should be read to obtain the output of \fIlist\fP.
+Process substitution is supported on systems that support named
+pipes (\fIFIFOs\fP) or the \fB/dev/fd\fP method of naming open files.

+and passed to commands as empty strings.
+Unquoted implicit null arguments, resulting from the expansion of

+If a parameter with no value is expanded within double quotes, a
+null argument results and is retained
+and passed to a command as an empty string.
+When a quoted null argument appears as part of a word whose expansion is
+non-null, the null argument is removed.
+That is, the word
+\f(CW\-d\(aq\^\(aq\fP becomes \f(CW\-d\fP after word splitting and
+null argument removal.
+.PP
+Note that if no expansion occurs, no splitting
+is performed.

+filenames matching the pattern
+(see
+.SM
+.B "Pattern Matching"
+below).
+If no matching filenames are found,

+.B nullglob
+is not enabled, the word is left unchanged.
+If the

+If the
+.B failglob
+shell option is set, and no matches are found, an error message
+is printed and the command is not executed.
+If the shell option
+.B nocaseglob
+is enabled, the match is performed without regard to the case
+of alphabetic characters.
+When a pattern is used for pathname expansion,
+the character
+.B ``.''
+at the start of a name or immediately following a slash
+must be matched explicitly, unless the shell option
+.B dotglob
+is set.
+In order to match the filenames
+.B ``.''

+When not matching pathnames, the

+character is not treated specially.
+When matching a pathname, the slash character must always be
+matched explicitly by a slash in the pattern, but in other matching
+contexts it can be matched by a special pattern character as described

+As above, ``.'' only has a special meaning when matching filenames.
+.PP
+Complicated extended pattern matching against long strings is slow,

+.SH REDIRECTION
+Before a command is executed, its input and output
+may be
+.I redirected
+using a special notation interpreted by the shell.
+\fIRedirection\fP allows commands' file handles to be
+duplicated, opened, closed,
+made to refer to different files,
+and can change the files the command reads from and writes to.
+Redirection may also be used to modify file handles in the
+current shell execution environment.
+The following redirection
+operators may precede or appear anywhere within a
+.I simple command
+or may follow a
+.IR command .
+Redirections are processed in the order they appear, from
+left to right.
+.PP
+Each redirection that may be preceded by a file descriptor number
+may instead be preceded by a word of the form {\fIvarname\fP}.
+In this case, for each redirection operator except
+>&- and <&-, the shell will allocate a file descriptor greater
+than or equal to 10 and assign it to \fIvarname\fP.
+If >&- or <&- is preceded
+by {\fIvarname\fP}, the value of \fIvarname\fP defines the file
+descriptor to close.
+If {\fIvarname\fP} is supplied, the redirection persists beyond
+the scope of the command, allowing the shell programmer to manage
+the file descriptor's lifetime manually.
+The \fBvarredir_close\fP shell option manages this behavior.
+.PP
+In the following descriptions, if the file descriptor number is
+omitted, and the first character of the redirection operator is
+.BR < ,
+the redirection refers to the standard input (file descriptor
+0).  If the first character of the redirection operator is
+.BR > ,
+the redirection refers to the standard output (file descriptor
+1).
+.PP
+The word following the redirection operator in the following
+descriptions, unless otherwise noted, is subjected to
+brace expansion, tilde expansion, parameter and variable expansion,
+command substitution, arithmetic expansion, quote removal,
+pathname expansion, and word splitting.
+If it expands to more than one word,
+.B bash
+reports an error.
+.PP
+Note that the order of redirections is significant.  For example,
+the command
+.RS
+.PP
+ls \fB>\fP dirlist 2\fB>&\fP1
+.RE
+.PP
+directs both standard output and standard error to the file
+.IR dirlist ,
+while the command

+ls 2\fB>&\fP1 \fB>\fP dirlist
+.RE
+.PP
+directs only the standard output to file
+.IR dirlist ,
+because the standard error was duplicated from the standard output
+before the standard output was redirected to
+.IR dirlist .
+.PP
+\fBBash\fP handles several filenames specially when they are used in
+redirections, as described in the following table.

+.SH ALIASES
+\fIAliases\fP allow a string to be substituted for a word when it is used
+as the first word of a simple command.
+The shell maintains a list of aliases that may be set and unset with the
+.B alias
+and
+.B unalias
+builtin commands (see
+.SM
+.B SHELL BUILTIN COMMANDS
+below).
+The first word of each simple command, if unquoted,
+is checked to see if it has an
+alias.  If so, that word is replaced by the text of the alias.
+The characters \fB/\fP, \fB$\fP, \fB\`\fP, and \fB=\fP and
+any of the shell \fImetacharacters\fP or quoting characters
+listed above may not appear in an alias name.
+The replacement text may contain any valid shell input,
+including shell metacharacters.
+The first word of the replacement text is tested
+for aliases, but a word that is identical to an alias being expanded
+is not expanded a second time.
+This means that one may alias
+.B ls
+to
+.BR "ls \-F" ,
+for instance, and
+.B bash
+does not try to recursively expand the replacement text.
+If the last character of the alias value is a
+.IR blank ,
+then the next command
+word following the alias is also checked for alias expansion.
+.PP
+Aliases are created and listed with the
+.B alias
+command, and removed with the
+.B unalias
+command.
+.PP
+There is no mechanism for using arguments in the replacement text.
+If arguments are needed, use a shell function (see
+.SM
+.B FUNCTIONS
+below).
+.PP
+Aliases are not expanded when the shell is not interactive, unless
+the
+.B expand_aliases
+shell option is set using
+.B shopt
+(see the description of
+.B shopt
+under
+.SM
+\fBSHELL BUILTIN COMMANDS\fP
+below).
+.PP
+The rules concerning the definition and use of aliases are
+somewhat confusing.
+.B Bash
+always reads at least one complete line of input,
+and all lines that make up a compound command,
+before executing any of the commands on that line or the compound command.
+Aliases are expanded when a
+command is read, not when it is executed.  Therefore, an
+alias definition appearing on the same line as another
+command does not take effect until the next line of input is read.
+The commands following the alias definition
+on that line are not affected by the new alias.
+This behavior is also an issue when functions are executed.
+Aliases are expanded when a function definition is read,
+not when the function is executed, because a function definition
+is itself a command.  As a consequence, aliases
+defined in a function are not available until after that
+function is executed.  To be safe, always put
+alias definitions on a separate line, and do not use
+.B alias
+in compound commands.
+.PP
+For almost every purpose, aliases are superseded by
+shell functions.
+.SH FUNCTIONS
+A shell function, defined as described above under
+.SM
+.BR "SHELL GRAMMAR" ,
+stores a series of commands for later execution.
+When the name of a shell function is used as a simple command name,
+the list of commands associated with that function name is executed.
+Functions are executed in the context of the
+current shell; no new process is created to interpret
+them (contrast this with the execution of a shell script).
+When a function is executed, the arguments to the
+function become the positional parameters
+during its execution.
+The special parameter
+.B #
+is updated to reflect the change.  Special parameter \fB0\fP
+is unchanged.
+The first element of the
+.SM
+.B FUNCNAME
+variable is set to the name of the function while the function
+is executing.
+.PP
+All other aspects of the shell execution
+environment are identical between a function and its caller
+with these exceptions: the
+.SM
+.B DEBUG
+and
+.B RETURN
+traps (see the description of the
+.B trap
+builtin under
+.SM
+.B SHELL BUILTIN COMMANDS
+below) are not inherited unless the function has been given the
+\fBtrace\fP attribute (see the description of the
+.SM
+.B declare
+builtin below) or the
+\fB\-o functrace\fP shell option has been enabled with
+the \fBset\fP builtin
+(in which case all functions inherit the \fBDEBUG\fP and \fBRETURN\fP traps),
+and the
+.SM
+.B ERR
+trap is not inherited unless the \fB\-o errtrace\fP shell option has
+been enabled.
+.PP
+Variables local to the function may be declared with the
+.B local
+builtin command (\fIlocal variables\fP).
+Ordinarily, variables and their values
+are shared between the function and its caller.
+If a variable is declared \fBlocal\fP, the variable's visible scope
+is restricted to that function and its children (including the functions
+it calls).
+.PP
+In the following description, the \fIcurrent scope\fP is a currently-
+executing function.
+Previous scopes consist of that function's caller and so on,
+back to the "global" scope, where the shell is not executing
+any shell function.
+Consequently, a local variable at the current scope is a variable
+declared using the \fBlocal\fP or \fBdeclare\fP builtins in the
+function that is currently executing.
+.PP
+Local variables "shadow" variables with the same name declared at
+previous scopes.
+For instance, a local variable declared in a function
+hides a global variable of the same name: references and assignments
+refer to the local variable, leaving the global variable unmodified.
+When the function returns, the global variable is once again visible.
+.PP
+The shell uses \fIdynamic scoping\fP to control a variable's visibility
+within functions.
+With dynamic scoping, visible variables and their values
+are a result of the sequence of function calls that caused execution
+to reach the current function.
+The value of a variable that a function sees depends
+on its value within its caller, if any, whether that caller is
+the "global" scope or another shell function.
+This is also the value that a local variable
+declaration "shadows", and the value that is restored when the function
+returns.
+.PP
+For example, if a variable \fIvar\fP is declared as local in function
+\fIfunc1\fP, and \fIfunc1\fP calls another function \fIfunc2\fP,
+references to \fIvar\fP made from within \fIfunc2\fP will resolve to the
+local variable \fIvar\fP from \fIfunc1\fP, shadowing any global variable
+named \fIvar\fP.
+.PP
+The \fBunset\fP builtin also acts using the same dynamic scope: if a
+variable is local to the current scope, \fBunset\fP will unset it;
+otherwise the unset will refer to the variable found in any calling scope
+as described above.
+If a variable at the current local scope is unset, it will remain so
+(appearing as unset)
+until it is reset in that scope or until the function returns.
+Once the function returns, any instance of the variable at a previous
+scope will become visible.
+If the unset acts on a variable at a previous scope, any instance of a
+variable with that name that had been shadowed will become visible
+(see below how the \fBlocalvar_unset\fP shell option changes this behavior).
+.PP
+The \fBFUNCNEST\fP variable, if set to a numeric value greater
+than 0, defines a maximum function nesting level.  Function
+invocations that exceed the limit cause the entire command to
+abort.
+.PP
+If the builtin command
+.B return
+is executed in a function, the function completes and
+execution resumes with the next command after the function
+call.
+Any command associated with the \fBRETURN\fP trap is executed
+before execution resumes.
+When a function completes, the values of the
+positional parameters and the special parameter
+.B #
+are restored to the values they had prior to the function's
+execution.
+.PP
+Function names and definitions may be listed with the
+.B \-f
+option to the
+.B declare
+or
+.B typeset
+builtin commands.  The
+.B \-F
+option to
+.B declare
+or
+.B typeset
+will list the function names only
+(and optionally the source file and line number, if the \fBextdebug\fP
+shell option is enabled).
+Functions may be exported so that child shell processes
+(those created when executing a separate shell invocation)
+automatically have them defined with the
+.B \-f
+option to the
+.B export
+builtin.
+A function definition may be deleted using the \fB\-f\fP option to
+the
+.B unset
+builtin.
+.PP
+Functions may be recursive.
+The \fBFUNCNEST\fP variable may be used to limit the depth of the
+function call stack and restrict the number of function invocations.
+By default, no limit is imposed on the number of recursive calls.
+.SH "ARITHMETIC EVALUATION"
+The shell allows arithmetic expressions to be evaluated, under
+certain circumstances (see the \fBlet\fP and \fBdeclare\fP builtin
+commands, the \fB((\fP compound command, and \fBArithmetic Expansion\fP).
+Evaluation is done in fixed-width integers with no check for overflow,
+though division by 0 is trapped and flagged as an error.
+The operators and their precedence, associativity, and values
+are the same as in the C language.
+The following list of operators is grouped into levels of

+Shell variables are allowed as operands; parameter expansion is
+performed before the expression is evaluated.
+Within an expression, shell variables may also be referenced by name
+without using the parameter expansion syntax.
+A shell variable that is null or unset evaluates to 0 when referenced
+by name without using the parameter expansion syntax.
+The value of a variable is evaluated as an arithmetic expression
+when it is referenced, or when a variable which has been given the
+\fIinteger\fP attribute using \fBdeclare \-i\fP is assigned a value.
+A null value evaluates to 0.
+A shell variable need not have its \fIinteger\fP attribute
+turned on to be used in an expression.
+.PP
+Integer constants follow the C language definition, without suffixes or
+character constants.
+Constants with a leading 0 are interpreted as octal numbers.
+A leading 0x or 0X denotes hexadecimal.
+Otherwise, numbers take the form [\fIbase#\fP]n, where the optional \fIbase\fP
+is a decimal number between 2 and 64 representing the arithmetic
+base, and \fIn\fP is a number in that base.
+If \fIbase#\fP is omitted, then base 10 is used.
+When specifying \fIn\fP,
+if a non-digit is required,
+the digits greater than 9 are represented by the lowercase letters,
+the uppercase letters, @, and _, in that order.
+If \fIbase\fP is less than or equal to 36, lowercase and uppercase
+letters may be used interchangeably to represent numbers between 10
+and 35.

+rules above.
+.SH "CONDITIONAL EXPRESSIONS"
+Conditional expressions are used by the \fB[[\fP compound command and
+the \fBtest\fP and \fB[\fP builtin commands to test file attributes
+and perform string and arithmetic comparisons.
+The \fBtest\fP and \fB[\fP commands determine their behavior based on
+the number of arguments; see the descriptions of those commands for any
+other command-specific actions.
+.PP
+Expressions are formed from the following unary or binary primaries.
+\fBBash\fP handles several filenames specially when they are used in
+expressions.
+If the operating system on which \fBbash\fP is running provides these
+special files, bash will use them; otherwise it will emulate them
+internally with this behavior:
+If any \fIfile\fP argument to one of the primaries is of the form
+\fI/dev/fd/n\fP, then file descriptor \fIn\fP is checked.
+If the \fIfile\fP argument to one of the primaries is one of
+\fI/dev/stdin\fP, \fI/dev/stdout\fP, or \fI/dev/stderr\fP, file
+descriptor 0, 1, or 2, respectively, is checked.

+When a simple command is executed, the shell performs the following

+.IP 1.
+The words that the parser has marked as variable assignments (those
+preceding the command name) and redirections are saved for later
+processing.
+.IP 2.
+The words that are not variable assignments or redirections are
+expanded.  If any words remain after expansion, the first word
+is taken to be the name of the command and the remaining words are
+the arguments.
+.IP 3.
+Redirections are performed as described above under
+.SM
+.BR REDIRECTION .
+.IP 4.
+The text after the \fB=\fP in each variable assignment undergoes tilde
+expansion, parameter expansion, command substitution, arithmetic expansion,
+and quote removal before being assigned to the variable.
+.PP
+If no command name results, the variable assignments affect the current
+shell environment.
+In the case of such a command (one that consists only of assignment
+statements and redirections), assignment statements are performed before
+redirections.
+Otherwise, the variables are added to the environment
+of the executed command and do not affect the current shell environment.
+If any of the assignments attempts to assign a value to a readonly variable,
+an error occurs, and the command exits with a non-zero status.
+.PP
+If no command name results, redirections are performed, but do not
+affect the current shell environment.  A redirection error causes the
+command to exit with a non-zero status.
+.PP
+If there is a command name left after expansion, execution proceeds as
+described below.  Otherwise, the command exits.  If one of the expansions
+contained a command substitution, the exit status of the command is
+the exit status of the last command substitution performed.  If there
+were no command substitutions, the command exits with a status of zero.
+.SH "COMMAND EXECUTION"
+After a command has been split into words, if it results in a
+simple command and an optional list of arguments, the following
+actions are taken.
+.PP
+If the command name contains no slashes, the shell attempts to
+locate it.  If there exists a shell function by that name, that
+function is invoked as described above in
+.SM
+.BR FUNCTIONS .
+If the name does not match a function, the shell searches for
+it in the list of shell builtins.  If a match is found, that
+builtin is invoked.
+.PP
+If the name is neither a shell function nor a builtin,
+and contains no slashes,
+.B bash
+searches each element of the
+.SM
+.B PATH
+for a directory containing an executable file by that name.
+.B Bash
+uses a hash table to remember the full pathnames of executable
+files (see
+.B hash
+under
+.SM
+.B "SHELL BUILTIN COMMANDS"
+below).
+A full search of the directories in
+.SM
+.B PATH
+is performed only if the command is not found in the hash table.
+If the search is unsuccessful, the shell searches for a defined shell
+function named \fBcommand_not_found_handle\fP.
+If that function exists, it is invoked in a separate execution environment
+with the original command and
+the original command's arguments as its arguments, and the function's
+exit status becomes the exit status of that subshell.
+If that function is not defined, the shell prints an error
+message and returns an exit status of 127.
+.PP
+If the search is successful, or if the command name contains
+one or more slashes, the shell executes the named program in a
+separate execution environment.
+Argument 0 is set to the name given, and the remaining arguments
+to the command are set to the arguments given, if any.
+.PP
+If this execution fails because the file is not in executable
+format, and the file is not a directory, it is assumed to be
+a \fIshell script\fP, a file
+containing shell commands, and the shell creates a
+new instance of itself
+to execute it.
+This subshell reinitializes itself, so
+that the effect is as if a new shell had been invoked
+to handle the script, with the exception that the locations of
+commands remembered by the parent (see
+.B hash
+below under
+.SM
+\fBSHELL BUILTIN COMMANDS\fP)
+are retained by the child.
+.PP
+If the program is a file beginning with
+.BR #! ,
+the remainder of the first line specifies an interpreter
+for the program.  The shell executes the
+specified interpreter on operating systems that do not
+handle this executable format themselves.  The arguments to the
+interpreter consist of a single optional argument following the
+interpreter name on the first line of the program, followed
+by the name of the program, followed by the command
+arguments, if any.

+creates a parameter for each name found, automatically marking
+it for
+.I export
+to child processes.  Executed commands inherit the environment.
+The
+.B export
+and
+.B declare \-x
+commands allow parameters and functions to be added to and
+deleted from the environment.  If the value of a parameter
+in the environment is modified, the new value becomes part
+of the environment, replacing the old.  The environment
+inherited by any executed command consists of the shell's
+initial environment, whose values may be modified in the shell,
+less any pairs removed by the
+.B unset
+command, plus any additions via the
+.B export
+and
+.B declare \-x
+commands.
+.PP
+The environment for any
+.I simple command
+or function may be augmented temporarily by prefixing it with
+parameter assignments, as described above in
+.SM
+.BR PARAMETERS .
+These assignment statements affect only the environment seen
+by that command.
+.PP
+If the
+.B \-k
+option is set (see the
+.B set
+builtin command below), then
+.I all
+parameter assignments are placed in the environment for a command,
+not just those that precede the command name.
+.PP
+When
+.B bash
+invokes an external command, the variable
+.B _
+is set to the full filename of the command and passed to that
+command in its environment.
+.SH "EXIT STATUS"
+The exit status of an executed command is the value returned by the
+\fIwaitpid\fP system call or equivalent function.  Exit statuses
+fall between 0 and 255, though, as explained below, the shell may
+use values above 125 specially.  Exit statuses from shell builtins and
+compound commands are also limited to this range.  Under certain
+circumstances, the shell will use special values to indicate specific
+failure modes.
+.PP
+For the shell's purposes, a command which exits with a
+zero exit status has succeeded.  An exit status of zero
+indicates success.  A non-zero exit status indicates failure.
+When a command terminates on a fatal signal \fIN\fP, \fBbash\fP uses
+the value of 128+\fIN\fP as the exit status.
+.PP
+If a command is not found, the child process created to
+execute it returns a status of 127.  If a command is found
+but is not executable, the return status is 126.
+.PP
+If a command fails because of an error during expansion or redirection,
+the exit status is greater than zero.
+.PP
+Shell builtin commands return a status of 0 (\fItrue\fP) if
+successful, and non-zero (\fIfalse\fP) if an error occurs
+while they execute.
+All builtins return an exit status of 2 to indicate incorrect usage,
+generally invalid options or missing arguments.
+.PP
+The exit status of the last command is available in the special
+parameter $?.
+.PP
+\fBBash\fP itself returns the exit status of the last command
+executed, unless a syntax error occurs, in which case it exits
+with a non-zero value.  See also the \fBexit\fP builtin
+command below.
+.SH SIGNALS
+When \fBbash\fP is interactive, in the absence of any traps, it ignores
+.SM
+.B SIGTERM
+(so that \fBkill 0\fP does not kill an interactive shell),
+and
+.SM
+.B SIGINT
+is caught and handled (so that the \fBwait\fP builtin is interruptible).
+In all cases, \fBbash\fP ignores
+.SM
+.BR SIGQUIT .
+If job control is in effect,
+.B bash
+ignores
+.SM
+.BR SIGTTIN ,
+.SM
+.BR SIGTTOU ,
+and
+.SM
+.BR SIGTSTP .
+.PP
+Non-builtin commands run by \fBbash\fP have signal handlers
+set to the values inherited by the shell from its parent.
+When job control is not in effect, asynchronous commands
+ignore
+.SM
+.B SIGINT
+and
+.SM
+.B SIGQUIT
+in addition to these inherited handlers.
+Commands run as a result of command substitution ignore the
+keyboard-generated job control signals
+.SM
+.BR SIGTTIN ,
+.SM
+.BR SIGTTOU ,
+and
+.SM
+.BR SIGTSTP .
+.PP
+The shell exits by default upon receipt of a
+.SM
+.BR SIGHUP .
+Before exiting, an interactive shell resends the
+.SM
+.B SIGHUP
+to all jobs, running or stopped.
+Stopped jobs are sent
+.SM
+.B SIGCONT
+to ensure that they receive the
+.SM
+.BR SIGHUP .
+To prevent the shell from
+sending the signal to a particular job, it should be removed from the
+jobs table with the
+.B disown
+builtin (see
+.SM
+.B "SHELL BUILTIN COMMANDS"
+below) or marked
+to not receive
+.SM
+.B SIGHUP
+using
+.BR "disown \-h" .
+.PP
+If the
+.B huponexit
+shell option has been set with
+.BR shopt ,
+.B bash
+sends a
+.SM
+.B SIGHUP
+to all jobs when an interactive login shell exits.
+.PP
+If \fBbash\fP is waiting for a command to complete and receives a signal
+for which a trap has been set, the trap will not be executed until
+the command completes.
+When \fBbash\fP is waiting for an asynchronous command via the \fBwait\fP
+builtin, the reception of a signal for which a trap has been set will
+cause the \fBwait\fP builtin to return immediately with an exit status
+greater than 128, immediately after which the trap is executed.
+.PP
+When job control is not enabled, and \fBbash\fP is waiting for a foreground
+command to complete, the shell receives keyboard-generated signals
+such as
+.SM
+.B SIGINT
+(usually generated by \fB^C\fP) that users commonly intend to send
+to that command.
+This happens because the shell and the command are in the
+same process group as the terminal, and \fB^C\fP sends
+.SM
+.B SIGINT
+to all processes in that process group.
+.PP
+When \fBbash\fP is running without job control enabled and receives 
+.SM
+.B SIGINT
+while waiting for a foreground command, it waits until that foreground
+command terminates and then decides what to do about the
+.SM
+.BR SIGINT :
+.IP 1.
+If the command terminates due to the
+.SM
+.BR SIGINT ,
+\fBbash\fP concludes
+that the user meant to end the entire script, and acts on the
+.SM
+.B SIGINT
+(e.g., by running a
+.SM
+.B SIGINT
+trap or exiting itself);
+.IP 2.
+If the command does not terminate due to
+.SM
+.BR SIGINT ,
+the program handled the
+.SM
+.B SIGINT
+itself and did not treat it as a fatal signal.
+In that case, \fBbash\fP does not treat
+.SM
+.B SIGINT
+as a fatal signal, either, instead assuming that the
+.SM
+.B SIGINT
+was used as part of the program's normal operation
+(e.g., emacs uses it to abort editing
+commands) or deliberately discarded.
+However, \fBbash\fP will run any
+trap set on
+.SM
+.BR SIGINT ,
+as it does with any other trapped signal it
+receives while it is waiting for the foreground command to
+complete, for compatibility.
+.SH "JOB CONTROL"
+.I Job control
+refers to the ability to selectively stop (\fIsuspend\fP)
+the execution of processes and continue (\fIresume\fP)
+their execution at a later point.  A user typically employs
+this facility via an interactive interface supplied jointly
+by the operating system kernel's terminal driver and
+.BR bash .
+.PP
+The shell associates a
+.I job
+with each pipeline.  It keeps a table of currently executing
+jobs, which may be listed with the
+.B jobs
+command.  When
+.B bash
+starts a job asynchronously (in the
+.IR background ),
+it prints a line that looks like:
+.RS
+.PP
+[1] 25647
+.RE
+.PP
+indicating that this job is job number 1 and that the process ID
+of the last process in the pipeline associated with this job is 25647.
+All of the processes in a single pipeline are members of the same job.
+.B Bash
+uses the
+.I job
+abstraction as the basis for job control.
+.PP
+To facilitate the implementation of the user interface to job
+control, the operating system maintains the notion of a \fIcurrent terminal
+process group ID\fP.  Members of this process group (processes whose
+process group ID is equal to the current terminal process group ID)
+receive keyboard-generated signals such as
+.SM
+.BR SIGINT .
+These processes are said to be in the
+.IR foreground .
+.I Background
+processes are those whose process group ID differs from the terminal's;
+such processes are immune to keyboard-generated signals.
+Only foreground processes are allowed to read from or, if the
+user so specifies with \f(CWstty tostop\fP, write to the
+terminal.
+Background processes which attempt to read from (write to when
+\f(CWstty tostop\fP is in effect) the
+terminal are sent a
+.SM
+.B SIGTTIN (SIGTTOU)
+signal by the kernel's terminal driver,
+which, unless caught, suspends the process.
+.PP
+If the operating system on which
+.B bash
+is running supports
+job control,
+.B bash
+contains facilities to use it.
+Typing the
+.I suspend
+character (typically
+.BR ^Z ,
+Control-Z) while a process is running
+causes that process to be stopped and returns control to
+.BR bash .
+Typing the
+.I "delayed suspend"
+character (typically
+.BR ^Y ,
+Control-Y) causes the process to be stopped when it
+attempts to read input from the terminal, and control to
+be returned to
+.BR bash .
+The user may then manipulate the state of this job, using the
+.B bg
+command to continue it in the background, the
+.B fg
+command to continue it in the foreground, or
+the
+.B kill
+command to kill it.  A \fB^Z\fP takes effect immediately,
+and has the additional side effect of causing pending output
+and typeahead to be discarded.
+.PP
+There are a number of ways to refer to a job in the shell.
+The character
+.B %
+introduces a job specification (\fIjobspec\fP).  Job number
+.I n
+may be referred to as
+.BR %n .
+A job may also be referred to using a prefix of the name used to
+start it, or using a substring that appears in its command line.
+For example,
+.B %ce
+refers to a stopped
+job whose command name begins with
+.BR ce .
+If a prefix matches more than one job,
+.B bash
+reports an error.  Using
+.BR %?ce ,
+on the other hand, refers to any job containing the string
+.B ce
+in its command line.  If the substring matches more than one job,
+.B bash
+reports an error.  The symbols
+.B %%
+and
+.B %+
+refer to the shell's notion of the
+.IR "current job" ,
+which is the last job stopped while it was in
+the foreground or started in the background.
+The
+.I "previous job"
+may be referenced using
+.BR %\- .
+If there is only a single job, \fB%+\fP and \fB%\-\fP can both be used
+to refer to that job.
+In output pertaining to jobs (e.g., the output of the
+.B jobs
+command), the current job is always flagged with a
+.BR + ,
+and the previous job with a
+.BR \- .
+A single % (with no accompanying job specification) also refers to the
+current job.
+.PP
+Simply naming a job can be used to bring it into the
+foreground:
+.B %1
+is a synonym for
+\fB``fg %1''\fP,
+bringing job 1 from the background into the foreground.
+Similarly,
+.B ``%1 &''
+resumes job 1 in the background, equivalent to
+\fB``bg %1''\fP.
+.PP
+The shell learns immediately whenever a job changes state.
+Normally,
+.B bash
+waits until it is about to print a prompt before reporting
+changes in a job's status so as to not interrupt
+any other output.  If the
+.B \-b
+option to the
+.B set
+builtin command
+is enabled,
+.B bash
+reports such changes immediately.
+Any trap on
+.SM
+.B SIGCHLD
+is executed for each child that exits.
+.PP
+If an attempt to exit
+.B bash
+is made while jobs are stopped (or, if the \fBcheckjobs\fP shell option has
+been enabled using the \fBshopt\fP builtin, running), the shell prints a
+warning message, and, if the \fBcheckjobs\fP option is enabled, lists the
+jobs and their statuses.
+The
+.B jobs
+command may then be used to inspect their status.
+If a second attempt to exit is made without an intervening command,
+the shell does not print another warning, and any stopped
+jobs are terminated.
+.PP
+When the shell is waiting for a job or process using the \fBwait\fP
+builtin, and job control is enabled, \fBwait\fP will return when the
+job changes state. The \fB\-f\fP option causes \fBwait\fP to wait
+until the job or process terminates before returning.
+.SH PROMPTING
+When executing interactively,
+.B bash
+displays the primary prompt
+.SM
+.B PS1
+when it is ready to read a command, and the secondary prompt
+.SM
+.B PS2
+when it needs more input to complete a command.
+.B Bash
+displays
+.SM
+.B PS0
+after it reads a command but before executing it.
+.B Bash
+displays
+.SM
+.B PS4
+as described above
+before tracing each command when the \fB\-x\fP option is enabled.
+.B Bash
+allows these prompt strings to be customized by inserting a number of
+backslash-escaped special characters that are decoded as follows:
+.RS
+.PD 0
+.TP
+.B \ea
+an ASCII bell character (07)
+.TP
+.B \ed
+the date in "Weekday Month Date" format (e.g., "Tue May 26")
+.TP
+.B \eD{\fIformat\fP}
+the \fIformat\fP is passed to \fIstrftime\fP(3) and the result is inserted
+into the prompt string; an empty \fIformat\fP results in a locale-specific
+time representation.  The braces are required
+.TP
+.B \ee
+an ASCII escape character (033)
+.TP
+.B \eh
+the hostname up to the first `.'
+.TP
+.B \eH
+the hostname
+.TP
+.B \ej
+the number of jobs currently managed by the shell
+.TP

+the basename of the shell's terminal device name
+.TP
+.B \en
+newline
+.TP

+carriage return
+.TP
+.B \es

+embed a terminal control sequence into the prompt
+.TP

+end a sequence of non-printing characters
+.PD
+.RE
+.PP
+The command number and the history number are usually different:
+the history number of a command is its position in the history
+list, which may include commands restored from the history file
+(see
+.SM
+.B HISTORY
+below), while the command number is the position in the sequence
+of commands executed during the current shell session.
+After the string is decoded, it is expanded via
+parameter expansion, command substitution, arithmetic
+expansion, and quote removal, subject to the value of the
+.B promptvars
+shell option (see the description of the
+.B shopt
+command under
+.SM
+.B "SHELL BUILTIN COMMANDS"
+below).
+This can have unwanted side effects if escaped portions of the string
+appear within command substitution or contain characters special to
+word expansion.
+.SH READLINE
+This is the library that handles reading input when using an interactive
+shell, unless the
+.B \-\-noediting
+option is given at shell invocation.
+Line editing is also used when using the \fB\-e\fP option to the
+\fBread\fP builtin.
+By default, the line editing commands are similar to those of Emacs.
+A vi-style line editing interface is also available.
+Line editing can be enabled at any time using the
+.B \-o emacs
+or
+.B \-o vi
+options to the
+.B set
+builtin (see
+.SM
+.B SHELL BUILTIN COMMANDS
+below).
+To turn off line editing after the shell is running, use the
+.B +o emacs
+or
+.B +o vi
+options to the
+.B set
+builtin.
+.SS "Readline Notation"
+In this section, the Emacs-style notation is used to denote
+keystrokes.  Control keys are denoted by C\-\fIkey\fR, e.g., C\-n
+means Control\-N.  Similarly,
+.I meta
+keys are denoted by M\-\fIkey\fR, so M\-x means Meta\-X.  (On keyboards
+without a
+.I meta
+key, M\-\fIx\fP means ESC \fIx\fP, i.e., press the Escape key
+then the
+.I x
+key.  This makes ESC the \fImeta prefix\fP.
+The combination M\-C\-\fIx\fP means ESC\-Control\-\fIx\fP,
+or press the Escape key
+then hold the Control key while pressing the
+.I x
+key.)
+.PP
+Readline commands may be given numeric
+.IR arguments ,
+which normally act as a repeat count.
+Sometimes, however, it is the sign of the argument that is significant.
+Passing a negative argument to a command that acts in the forward
+direction (e.g., \fBkill\-line\fP) causes that command to act in a
+backward direction.
+Commands whose behavior with arguments deviates from this are noted
+below.
+.PP
+When a command is described as \fIkilling\fP text, the text
+deleted is saved for possible future retrieval
+(\fIyanking\fP).  The killed text is saved in a
+\fIkill ring\fP.  Consecutive kills cause the text to be
+accumulated into one unit, which can be yanked all at once.
+Commands which do not kill text separate the chunks of text
+on the kill ring.
+.SS "Readline Initialization"
+Readline is customized by putting commands in an initialization
+file (the \fIinputrc\fP file).
+The name of this file is taken from the value of the
+.SM
+.B INPUTRC
+variable.  If that variable is unset, the default is
+.IR ~/.inputrc .
+If that file  does not exist or cannot be read, the ultimate default is
+.IR /etc/inputrc .
+When a program which uses the readline library starts up, the
+initialization file is read, and the key bindings and variables
+are set.
+There are only a few basic constructs allowed in the
+readline initialization file.
+Blank lines are ignored.
+Lines beginning with a \fB#\fP are comments.
+Lines beginning with a \fB$\fP indicate conditional constructs.
+Other lines denote key bindings and variable settings.
+.PP
+The default key-bindings may be changed with an
+.I inputrc
+file.
+Other programs that use this library may add their own commands
+and bindings.
+.PP
+For example, placing
+.RS
+.PP
+M\-Control\-u: universal\-argument
+.RE
+or
+.RS
+C\-Meta\-u: universal\-argument
+.RE
+into the
+.I inputrc
+would make M\-C\-u execute the readline command
+.IR universal\-argument .
+.PP
+The following symbolic character names are recognized:
+.IR RUBOUT ,
+.IR DEL ,
+.IR ESC ,
+.IR LFD ,
+.IR NEWLINE ,
+.IR RET ,
+.IR RETURN ,
+.IR SPC ,
+.IR SPACE ,
+and
+.IR TAB .
+.PP
+In addition to command names, readline allows keys to be bound
+to a string that is inserted when the key is pressed (a \fImacro\fP).
+.SS "Readline Key Bindings"
+The syntax for controlling key bindings in the
+.I inputrc
+file is simple.  All that is required is the name of the
+command or the text of a macro and a key sequence to which
+it should be bound.  The name may be specified in one of two ways:
+as a symbolic key name, possibly with \fIMeta\-\fP or \fIControl\-\fP
+prefixes, or as a key sequence.
+.PP
+When using the form \fBkeyname\fP:\^\fIfunction\-name\fP or \fImacro\fP,
+.I keyname
+is the name of a key spelled out in English.  For example:
+.sp
+.RS
+Control-u: universal\-argument
+.br
+Meta-Rubout: backward-kill-word
+.br
+Control-o: "> output"
+.RE
+.LP
+In the above example,
+.I C\-u
+is bound to the function
+.BR universal\-argument ,
+.I M\-DEL
+is bound to the function
+.BR backward\-kill\-word ,
+and
+.I C\-o
+is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+.if t \f(CW> output\fP
+.if n ``> output''
+into the line).
+.PP
+In the second form, \fB"keyseq"\fP:\^\fIfunction\-name\fP or \fImacro\fP,
+.B keyseq
+differs from
+.B keyname
+above in that strings denoting
+an entire key sequence may be specified by placing the sequence
+within double quotes.  Some GNU Emacs style key escapes can be
+used, as in the following example, but the symbolic character names
+are not recognized.
+.sp
+.RS
+"\eC\-u": universal\-argument
+.br
+"\eC\-x\eC\-r": re\-read\-init\-file
+.br
+"\ee[11~": "Function Key 1"
+.RE
+.PP
+In this example,
+.I C\-u
+is again bound to the function
+.BR universal\-argument .
+.I "C\-x C\-r"
+is bound to the function
+.BR re\-read\-init\-file ,
+and
+.I "ESC [ 1 1 ~"
+is bound to insert the text
+.if t \f(CWFunction Key 1\fP.
+.if n ``Function Key 1''.

+.PP
+.B Bash
+allows the current readline key bindings to be displayed or modified

+builtin command.  The editing mode may be switched during interactive
+use by using the
+.B \-o
+option to the
+.B set
+builtin command (see
+.SM
+.B SHELL BUILTIN COMMANDS
+below).
+.SS "Readline Variables"
+Readline has variables that can be used to further customize its
+behavior.  A variable may be set in the
+.I inputrc
+file with a statement of the form
+.RS
+.PP
+\fBset\fP \fIvariable\-name\fP \fIvalue\fP
+.RE
+or using the \fBbind\fP builtin command (see
+.SM
+.B SHELL BUILTIN COMMANDS
+below).
+.PP
+Except where noted, readline variables can take the values
+.B On
+or
+.B Off
+(without regard to case).
+Unrecognized variable names are ignored.
+When a variable value is read, empty or null values, "on" (case-insensitive),
+and "1" are equivalent to \fBOn\fP.  All other values are equivalent to
+\fBOff\fP.
+The variables and their default values are:
+.PP
+.PD 0
+.TP
+.B active\-region\-start\-color   
+A string variable that controls the text color and background when displaying
+the text in the active region (see the description of
+\fBenable\-active\-region\fP below).
+This string must not take up any physical character positions on the display,
+so it should consist only of terminal escape sequences.
+It is output to the terminal before displaying the text in the active region.
+This variable is reset to the default value whenever the terminal type changes.
+The default value is the string that puts the terminal in standout mode,
+as obtained from the terminal's terminfo description.
+A sample value might be \f(CW"\ee[01;33m"\fP.
+.TP
+.B active\-region\-end\-color     
+A string variable that "undoes" the effects of \fBactive\-region\-start\-color\fP 
+and restores "normal" terminal display appearance after displaying text
+in the active region.
+This string must not take up any physical character positions on the display,
+so it should consist only of terminal escape sequences.
+It is output to the terminal after displaying the text in the active region.
+This variable is reset to the default value whenever the terminal type changes.
+The default value is the string that restores the terminal from standout mode,
+as obtained from the terminal's terminfo description.
+A sample value might be \f(CW"\ee[0m"\fP.
+.TP
+.B bell\-style (audible)
+Controls what happens when readline wants to ring the terminal bell.
+If set to \fBnone\fP, readline never rings the bell.  If set to
+\fBvisible\fP, readline uses a visible bell if one is available.
+If set to \fBaudible\fP, readline attempts to ring the terminal's bell.
+.TP
+.B bind\-tty\-special\-chars (On)
+If set to \fBOn\fP, readline attempts to bind the control characters
+treated specially by the kernel's terminal driver to their readline
+equivalents.
+.TP
+.B blink\-matching\-paren (Off)
+If set to \fBOn\fP, readline attempts to briefly move the cursor to an
+opening parenthesis when a closing parenthesis is inserted.
+.TP
+.B colored\-completion\-prefix (Off)
+If set to \fBOn\fP, when listing completions, readline displays the
+common prefix of the set of possible completions using a different color.
+The color definitions are taken from the value of the \fBLS_COLORS\fP
+environment variable.
+If there is a color definition in \fB$LS_COLORS\fP for the custom suffix
+"readline-colored-completion-prefix", readline uses this color for
+the common prefix instead of its default.
+.TP
+.B colored\-stats (Off)
+If set to \fBOn\fP, readline displays possible completions using different
+colors to indicate their file type.
+The color definitions are taken from the value of the \fBLS_COLORS\fP
+environment variable.
+.TP
+.B comment\-begin (``#'')
+The string that is inserted when the readline
+.B insert\-comment
+command is executed.
+This command is bound to
+.B M\-#
+in emacs mode and to
+.B #
+in vi command mode.
+.TP
+.B completion\-display\-width (\-1)
+The number of screen columns used to display possible matches
+when performing completion.
+The value is ignored if it is less than 0 or greater than the terminal
+screen width.
+A value of 0 will cause matches to be displayed one per line.
+The default value is \-1.
+.TP
+.B completion\-ignore\-case (Off)
+If set to \fBOn\fP, readline performs filename matching and completion
+in a case\-insensitive fashion.
+.TP
+.B completion\-map\-case (Off)
+If set to \fBOn\fP, and \fBcompletion\-ignore\-case\fP is enabled, readline
+treats hyphens (\fI\-\fP) and underscores (\fI_\fP) as equivalent when
+performing case\-insensitive filename matching and completion.
+.TP
+.B completion\-prefix\-display\-length (0)
+The length in characters of the common prefix of a list of possible
+completions that is displayed without modification.  When set to a
+value greater than zero, common prefixes longer than this value are
+replaced with an ellipsis when displaying possible completions.
+.TP
+.B completion\-query\-items (100)
+This determines when the user is queried about viewing
+the number of possible completions
+generated by the \fBpossible\-completions\fP command.
+It may be set to any integer value greater than or equal to zero.
+If the number of possible completions is greater than
+or equal to the value of this variable,
+readline will ask whether or not the user wishes to view them;
+otherwise they are simply listed on the terminal.
+A zero value means readline should never ask; negative values are
+treated as zero.
+.TP
+.B convert\-meta (On)
+If set to \fBOn\fP, readline will convert characters with the
+eighth bit set to an ASCII key sequence
+by stripping the eighth bit and prefixing an
+escape character (in effect, using escape as the \fImeta prefix\fP).
+The default is \fIOn\fP, but readline will set it to \fIOff\fP if the
+locale contains eight-bit characters.
+This variable is dependent on the \fBLC_CTYPE\fP locale category, and 
+may change if the locale is changed.
+.TP
+.B disable\-completion (Off)
+If set to \fBOn\fP, readline will inhibit word completion.  Completion
+characters will be inserted into the line as if they had been
+mapped to \fBself-insert\fP.
+.TP
+.B echo\-control\-characters (On)
+When set to \fBOn\fP, on operating systems that indicate they support it,
+readline echoes a character corresponding to a signal generated from the
+keyboard.
+.TP
+.B editing\-mode (emacs)
+Controls whether readline begins with a set of key bindings similar
+to \fIEmacs\fP or \fIvi\fP.
+.B editing\-mode
+can be set to either
+.B emacs
+or
+.BR vi .
+.TP
+.B emacs\-mode\-string (@)
+If the \fIshow\-mode\-in\-prompt\fP variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when emacs editing mode is active.  The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the \e1 and \e2 escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+.TP
+.B enable\-active\-region (On)
+The \fIpoint\fP is the current cursor position, and \fImark\fP refers  
+to a saved cursor position.   
+The text between the point and mark is referred to as the \fIregion\fP.  
+When this variable is set to \fIOn\fP, readline allows certain commands
+to designate the region as \fIactive\fP.  
+When the region is active, readline highlights the text in the region using
+the value of the \fBactive\-region\-start\-color\fP, which defaults to the
+string that enables
+the terminal's standout mode.
+The active region shows the text inserted by bracketed-paste and any
+matching text found by incremental and non-incremental history searches.
+.TP
+.B enable\-bracketed\-paste (On)
+When set to \fBOn\fP, readline configures the terminal to insert each
+paste into the editing buffer as a single string of characters, instead
+of treating each character as if it had been read from the keyboard.
+This prevents readline from executing any editing commands bound to key
+sequences appearing in the pasted text.
+.TP
+.B enable\-keypad (Off)
+When set to \fBOn\fP, readline will try to enable the application
+keypad when it is called.  Some systems need this to enable the
+arrow keys.
+.TP
+.B enable\-meta\-key (On)
+When set to \fBOn\fP, readline will try to enable any meta modifier
+key the terminal claims to support when it is called.  On many terminals,
+the meta key is used to send eight-bit characters.
+.TP
+.B expand\-tilde (Off)
+If set to \fBOn\fP, tilde expansion is performed when readline
+attempts word completion.
+.TP
+.B history\-preserve\-point (Off)
+If set to \fBOn\fP, the history code attempts to place point at the
+same location on each history line retrieved with \fBprevious-history\fP
+or \fBnext-history\fP.
+.TP
+.B history\-size (unset)
+Set the maximum number of history entries saved in the history list.
+If set to zero, any existing history entries are deleted and no new entries
+are saved.
+If set to a value less than zero, the number of history entries is not
+limited.
+By default, the number of history entries is set to the value of the
+\fBHISTSIZE\fP shell variable.
+If an attempt is made to set \fIhistory\-size\fP to a non-numeric value,
+the maximum number of history entries will be set to 500.
+.TP
+.B horizontal\-scroll\-mode (Off)
+When set to \fBOn\fP, makes readline use a single line for display,
+scrolling the input horizontally on a single screen line when it
+becomes longer than the screen width rather than wrapping to a new line.
+This setting is automatically enabled for terminals of height 1.
+.TP
+.B input\-meta (Off)
+If set to \fBOn\fP, readline will enable eight-bit input (that is,
+it will not strip the eighth bit from the characters it reads),
+regardless of what the terminal claims it can support.  The name
+.B meta\-flag
+is a synonym for this variable.
+The default is \fIOff\fP, but readline will set it to \fIOn\fP if the
+locale contains eight-bit characters.
+This variable is dependent on the \fBLC_CTYPE\fP locale category, and 
+may change if the locale is changed.
+.TP
+.B isearch\-terminators (``C\-[C\-J'')
+The string of characters that should terminate an incremental
+search without subsequently executing the character as a command.
+If this variable has not been given a value, the characters
+\fIESC\fP and \fIC\-J\fP will terminate an incremental search.
+.TP
+.B keymap (emacs)
+Set the current readline keymap.  The set of valid keymap names is
+\fIemacs, emacs\-standard, emacs\-meta, emacs\-ctlx, vi,
+vi\-command\fP, and
+.IR vi\-insert .
+\fIvi\fP is equivalent to \fIvi\-command\fP; \fIemacs\fP is
+equivalent to \fIemacs\-standard\fP.  The default value is
+.IR emacs ;
+the value of
+.B editing\-mode
+also affects the default keymap.
+.TP
+.B keyseq\-timeout (500)
+Specifies the duration \fIreadline\fP will wait for a character when reading an
+ambiguous key sequence (one that can form a complete key sequence using
+the input read so far, or can take additional input to complete a longer
+key sequence).
+If no input is received within the timeout, \fIreadline\fP will use the shorter
+but complete key sequence.
+The value is specified in milliseconds, so a value of 1000 means that
+\fIreadline\fP will wait one second for additional input.
+If this variable is set to a value less than or equal to zero, or to a
+non-numeric value, \fIreadline\fP will wait until another key is pressed to
+decide which key sequence to complete.
+.TP
+.B mark\-directories (On)
+If set to \fBOn\fP, completed directory names have a slash
+appended.
+.TP
+.B mark\-modified\-lines (Off)
+If set to \fBOn\fP, history lines that have been modified are displayed
+with a preceding asterisk (\fB*\fP).
+.TP
+.B mark\-symlinked\-directories (Off)
+If set to \fBOn\fP, completed names which are symbolic links to directories
+have a slash appended (subject to the value of
+\fBmark\-directories\fP).
+.TP
+.B match\-hidden\-files (On)
+This variable, when set to \fBOn\fP, causes readline to match files whose
+names begin with a `.' (hidden files) when performing filename
+completion.
+If set to \fBOff\fP, the leading `.' must be
+supplied by the user in the filename to be completed.
+.TP
+.B menu\-complete\-display\-prefix (Off)
+If set to \fBOn\fP, menu completion displays the common prefix of the
+list of possible completions (which may be empty) before cycling through
+the list.
+.TP
+.B output\-meta (Off)
+If set to \fBOn\fP, readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence.
+The default is \fIOff\fP, but readline will set it to \fIOn\fP if the
+locale contains eight-bit characters.
+This variable is dependent on the \fBLC_CTYPE\fP locale category, and 
+may change if the locale is changed.
+.TP
+.B page\-completions (On)
+If set to \fBOn\fP, readline uses an internal \fImore\fP-like pager
+to display a screenful of possible completions at a time.
+.TP
+.B print\-completions\-horizontally (Off)
+If set to \fBOn\fP, readline will display completions with matches
+sorted horizontally in alphabetical order, rather than down the screen.
+.TP
+.B revert\-all\-at\-newline (Off)
+If set to \fBOn\fP, readline will undo all changes to history lines
+before returning when \fBaccept\-line\fP is executed.  By default,
+history lines may be modified and retain individual undo lists across
+calls to \fBreadline\fP.
+.TP
+.B show\-all\-if\-ambiguous (Off)
+This alters the default behavior of the completion functions.  If
+set to
+.BR On ,
+words which have more than one possible completion cause the
+matches to be listed immediately instead of ringing the bell.
+.TP
+.B show\-all\-if\-unmodified (Off)
+This alters the default behavior of the completion functions in
+a fashion similar to \fBshow\-all\-if\-ambiguous\fP.
+If set to
+.BR On ,
+words which have more than one possible completion without any
+possible partial completion (the possible completions don't share
+a common prefix) cause the matches to be listed immediately instead
+of ringing the bell.
+.TP
+.B show\-mode\-in\-prompt (Off)
+If set to \fBOn\fP, add a string to the beginning of the prompt
+indicating the editing mode: emacs, vi command, or vi insertion.
+The mode strings are user-settable (e.g., \fIemacs\-mode\-string\fP).
+.TP
+.B skip\-completed\-text (Off)
+If set to \fBOn\fP, this alters the default completion behavior when
+inserting a single match into the line.  It's only active when
+performing completion in the middle of a word.  If enabled, readline
+does not insert characters from the completion that match characters
+after point in the word being completed, so portions of the word
+following the cursor are not duplicated.
+.TP
+.B vi\-cmd\-mode\-string ((cmd))
+If the \fIshow\-mode\-in\-prompt\fP variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when vi editing mode is active and in command mode.
+The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the \e1 and \e2 escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+.TP
+.B vi\-ins\-mode\-string ((ins))
+If the \fIshow\-mode\-in\-prompt\fP variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when vi editing mode is active and in insertion mode.
+The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the \e1 and \e2 escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+.TP
+.B visible\-stats (Off)
+If set to \fBOn\fP, a character denoting a file's type as reported
+by \fIstat\fP(2) is appended to the filename when listing possible
+completions.
+.PD
+.SS "Readline Conditional Constructs"
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests.  There are four parser directives used.
+.IP \fB$if\fP
+The
+.B $if
+construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+readline.  The text of the test, after any comparison operator,
+ extends to the end of the line;
+unless otherwise noted, no characters are required to isolate it.
+.RS
+.IP \fBmode\fP
+The \fBmode=\fP form of the \fB$if\fP directive is used to test
+whether readline is in emacs or vi mode.
+This may be used in conjunction
+with the \fBset keymap\fP command, for instance, to set bindings in
+the \fIemacs\-standard\fP and \fIemacs\-ctlx\fP keymaps only if
+readline is starting out in emacs mode.
+.IP \fBterm\fP
+The \fBterm=\fP form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys.  The word on the right side of the
+.B =
+is tested against both the full name of the terminal and the portion
+of the terminal name before the first \fB\-\fP.  This allows
+.I sun
+to match both
+.I sun
+and
+.IR sun\-cmd ,
+for instance.
+.IP \fBversion\fP
+The \fBversion\fP test may be used to perform comparisons against
+specific readline versions.
+The \fBversion\fP expands to the current readline version.
+The set of comparison operators includes
+.BR = ,
+(and
+.BR == ),
+.BR != ,
+.BR <= ,
+.BR >= ,
+.BR < ,
+and
+.BR > .
+The version number supplied on the right side of the operator consists
+of a major version number, an optional decimal point, and an optional
+minor version (e.g., \fB7.1\fP). If the minor version is omitted, it
+is assumed to be \fB0\fP.
+The operator may be separated from the string \fBversion\fP
+and from the version number argument by whitespace.
+.IP \fBapplication\fP
+The \fBapplication\fP construct is used to include
+application-specific settings.  Each program using the readline
+library sets the \fIapplication name\fP, and an initialization
+file can test for a particular value.
+This could be used to bind key sequences to functions useful for
+a specific program.  For instance, the following command adds a
+key sequence that quotes the current or previous word in \fBbash\fP:
+.sp 1
+.RS
+.nf
+\fB$if\fP Bash
+# Quote the current or previous word
+"\eC\-xq": "\eeb\e"\eef\e""
+\fB$endif\fP
+.fi
+.RE
+.IP \fIvariable\fP
+The \fIvariable\fP construct provides simple equality tests for readline
+variables and values.
+The permitted comparison operators are \fI=\fP, \fI==\fP, and \fI!=\fP.
+The variable name must be separated from the comparison operator by
+whitespace; the operator may be separated from the value on the right hand
+side by whitespace.
+Both string and boolean variables may be tested. Boolean variables must be
+tested against the values \fIon\fP and \fIoff\fP.
+.RE
+.IP \fB$endif\fP
+This command, as seen in the previous example, terminates an
+\fB$if\fP command.
+.IP \fB$else\fP
+Commands in this branch of the \fB$if\fP directive are executed if
+the test fails.
+.IP \fB$include\fP
+This directive takes a single filename as an argument and reads commands
+and bindings from that file.  For example, the following directive
+would read \fI/etc/inputrc\fP:
+.sp 1
+.RS
+.nf
+\fB$include\fP \^ \fI/etc/inputrc\fP
+.fi
+.RE
+.SS Searching
+Readline provides commands for searching through the command history
+(see
+.SM
+.B HISTORY
+below) for lines containing a specified string.
+There are two search modes:
+.I incremental
+and
+.IR non-incremental .
+.PP
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+The characters present in the value of the \fBisearch-terminators\fP
+variable are used to terminate an incremental search.
+If that variable has not been assigned a value the Escape and
+Control-J characters will terminate an incremental search.
+Control-G will abort an incremental search and restore the original
+line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+.PP
+To find other matching entries in the history list, type Control-S or
+Control-R as appropriate.
+This will search backward or forward in the history for the next
+entry matching the search string typed so far.
+Any other key sequence bound to a readline command will terminate
+the search and execute that command.
+For instance, a \fInewline\fP will terminate the search and accept
+the line, thereby executing the command from the history list.
+.PP
+Readline remembers the last incremental search string.  If two
+Control-Rs are typed without any intervening characters defining a
+new search string, any remembered search string is used.
+.PP
+Non-incremental searches read the entire search string before starting
+to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.
+.SS "Readline Command Names"
+The following is a list of the names of the commands and the default
+key sequences to which they are bound.
+Command names without an accompanying key sequence are unbound by default.
+In the following descriptions, \fIpoint\fP refers to the current cursor
+position, and \fImark\fP refers to a cursor position saved by the
+\fBset\-mark\fP command.
+The text between the point and mark is referred to as the \fIregion\fP.

+.B yank\-nth\-arg (M\-C\-y)
+Insert the first argument to the previous command (usually
+the second word on the previous line) at point.
+With an argument
+.IR n ,
+insert the \fIn\fPth word from the previous command (the words
+in the previous command begin with word 0).  A negative argument
+inserts the \fIn\fPth word from the end of the previous command.
+Once the argument \fIn\fP is computed, the argument is extracted

+.TP
+.B
+yank\-last\-arg (M\-.\^, M\-_\^)
+Insert the last argument to the previous command (the last word of
+the previous history entry).
+With a numeric argument, behave exactly like \fByank\-nth\-arg\fP.
+Successive calls to \fByank\-last\-arg\fP move back through the history
+list, inserting the last word (or the word specified by the argument to
+the first call) of each line in turn.
+Any numeric argument supplied to these successive calls determines
+the direction to move through the history.  A negative argument switches
+the direction through the history (back or forward).
+The history expansion facilities are used to extract the last word,
+as if the "!$" history expansion had been specified.

+.SS Programmable Completion
+When word completion is attempted for an argument to a command for
+which a completion specification (a \fIcompspec\fP) has been defined
+using the \fBcomplete\fP builtin (see
+.SM
+.B "SHELL BUILTIN COMMANDS"
+below), the programmable completion facilities are invoked.
+.PP
+First, the command name is identified.
+If the command word is the empty string (completion attempted at the
+beginning of an empty line), any compspec defined with
+the \fB\-E\fP option to \fBcomplete\fP is used.
+If a compspec has been defined for that command, the
+compspec is used to generate the list of possible completions for the word.
+If the command word is a full pathname, a compspec for the full
+pathname is searched for first.
+If no compspec is found for the full pathname, an attempt is made to
+find a compspec for the portion following the final slash.
+If those searches do not result in a compspec, any compspec defined with
+the \fB\-D\fP option to \fBcomplete\fP is used as the default.
+If there is no default compspec, \fBbash\fP attempts alias expansion
+on the command word as a final resort, and attempts to find a compspec
+for the command word from any successful expansion.
+.PP
+Once a compspec has been found, it is used to generate the list of
+matching words.
+If a compspec is not found, the default \fBbash\fP completion as
+described above under \fBCompleting\fP is performed.
+.PP
+First, the actions specified by the compspec are used.
+Only matches which are prefixed by the word being completed are
+returned.
+When the
+.B \-f
+or
+.B \-d
+option is used for filename or directory name completion, the shell
+variable
+.SM
+.B FIGNORE
+is used to filter the matches.
+.PP
+Any completions specified by a pathname expansion pattern to the
+\fB\-G\fP option are generated next.
+The words generated by the pattern need not match the word
+being completed.
+The
+.SM
+.B GLOBIGNORE
+shell variable is not used to filter the matches, but the
+.SM
+.B FIGNORE
+variable is used.
+.PP
+Next, the string specified as the argument to the \fB\-W\fP option
+is considered.
+The string is first split using the characters in the
+.SM
+.B IFS
+special variable as delimiters.
+Shell quoting is honored.
+Each word is then expanded using
+brace expansion, tilde expansion, parameter and variable expansion,
+command substitution, and arithmetic expansion,
+as described above under
+.SM
+.BR EXPANSION .
+The results are split using the rules described above under
+\fBWord Splitting\fP.
+The results of the expansion are prefix-matched against the word being
+completed, and the matching words become the possible completions.
+.PP
+After these matches have been generated, any shell function or command
+specified with the \fB\-F\fP and \fB\-C\fP options is invoked.
+When the command or function is invoked, the
+.SM
+.BR COMP_LINE ,
+.SM
+.BR COMP_POINT ,
+.SM
+.BR COMP_KEY ,
+and
+.SM
+.B COMP_TYPE
+variables are assigned values as described above under
+\fBShell Variables\fP.
+If a shell function is being invoked, the
+.SM
+.B COMP_WORDS
+and
+.SM
+.B COMP_CWORD
+variables are also set.
+When the function or command is invoked,
+the first argument (\fB$1\fP) is the name of the command whose arguments are
+being completed,
+the second argument (\fB$2\fP) is the word being completed,
+and the third argument (\fB$3\fP) is the word preceding the word being
+completed on the current command line.
+No filtering of the generated completions against the word being completed
+is performed; the function or command has complete freedom in generating
+the matches.
+.PP
+Any function specified with \fB\-F\fP is invoked first.
+The function may use any of the shell facilities, including the
+\fBcompgen\fP builtin described below, to generate the matches.
+It must put the possible completions in the
+.SM
+.B COMPREPLY
+array variable, one per array element.
+.PP
+Next, any command specified with the \fB\-C\fP option is invoked
+in an environment equivalent to command substitution.
+It should print a list of completions, one per line, to the
+standard output.
+Backslash may be used to escape a newline, if necessary.
+.PP
+After all of the possible completions are generated, any filter
+specified with the \fB\-X\fP option is applied to the list.
+The filter is a pattern as used for pathname expansion; a \fB&\fP
+in the pattern is replaced with the text of the word being completed.
+A literal \fB&\fP may be escaped with a backslash; the backslash
+is removed before attempting a match.
+Any completion that matches the pattern will be removed from the list.
+A leading \fB!\fP negates the pattern; in this case any completion
+not matching the pattern will be removed.
+If the
+.B nocasematch
+shell option is enabled, the match is performed without regard to the case
+of alphabetic characters.
+.PP
+Finally, any prefix and suffix specified with the \fB\-P\fP and \fB\-S\fP
+options are added to each member of the completion list, and the result is
+returned to the readline completion code as the list of possible
+completions.
+.PP
+If the previously-applied actions do not generate any matches, and the
+\fB\-o dirnames\fP option was supplied to \fBcomplete\fP when the
+compspec was defined, directory name completion is attempted.
+.PP
+If the \fB\-o plusdirs\fP option was supplied to \fBcomplete\fP when the
+compspec was defined, directory name completion is attempted and any
+matches are added to the results of the other actions.
+.PP
+By default, if a compspec is found, whatever it generates is returned
+to the completion code as the full set of possible completions.
+The default \fBbash\fP completions are not attempted, and the readline
+default of filename completion is disabled.
+If the \fB\-o bashdefault\fP option was supplied to \fBcomplete\fP when
+the compspec was defined, the \fBbash\fP default completions are attempted
+if the compspec generates no matches.
+If the \fB\-o default\fP option was supplied to \fBcomplete\fP when the
+compspec was defined, readline's default completion will be performed
+if the compspec (and, if attempted, the default \fBbash\fP completions)
+generate no matches.
+.PP
+When a compspec indicates that directory name completion is desired,
+the programmable completion functions force readline to append a slash
+to completed names which are symbolic links to directories, subject to
+the value of the \fBmark\-directories\fP readline variable, regardless
+of the setting of the \fBmark-symlinked\-directories\fP readline variable.
+.PP
+There is some support for dynamically modifying completions.  This is
+most useful when used in combination with a default completion specified
+with \fBcomplete \-D\fP.
+It's possible for shell functions executed as completion
+handlers to indicate that completion should be retried by returning an
+exit status of 124.  If a shell function returns 124, and changes
+the compspec associated with the command on which completion is being
+attempted (supplied as the first argument when the function is executed),
+programmable completion restarts from the beginning, with an
+attempt to find a new compspec for that command.  This allows a set of
+completions to be built dynamically as completion is attempted, rather than
+being loaded all at once.
+.PP
+For instance, assuming that there is a library of compspecs, each kept in a
+file corresponding to the name of the command, the following default
+completion function would load completions dynamically:
+.PP
+\f(CW_completion_loader()
+.br
+{
+.br
+	. "/etc/bash_completion.d/$1.sh" >/dev/null 2>&1 && return 124
+.br
+}
+.br
+complete -D -F _completion_loader -o bashdefault -o default
+.br
+\fP
+.SH HISTORY
+When the
+.B \-o history
+option to the
+.B set
+builtin is enabled, the shell provides access to the
+\fIcommand history\fP,
+the list of commands previously typed.
+The value of the
+.SM
+.B HISTSIZE
+variable is used as the
+number of commands to save in a history list.
+The text of the last
+.SM
+.B HISTSIZE
+commands (default 500) is saved.  The shell
+stores each command in the history list prior to parameter and
+variable expansion (see
+.SM
+.B EXPANSION
+above) but after history expansion is performed, subject to the
+values of the shell variables
+.SM
+.B HISTIGNORE
+and
+.SM
+.BR HISTCONTROL .
+.PP
+On startup, the history is initialized from the file named by
+the variable
+.SM
+.B HISTFILE
+(default \fI~/.bash_history\fP).
+The file named by the value of
+.SM
+.B HISTFILE
+is truncated, if necessary, to contain no more than
+the number of lines specified by the value of
+.SM
+.BR HISTFILESIZE .
+If \fBHISTFILESIZE\fP is unset, or set to null, a non-numeric value,
+or a numeric value less than zero, the history file is not truncated.
+When the history file is read,
+lines beginning with the history comment character followed immediately
+by a digit are interpreted as timestamps for the following history line.
+These timestamps are optionally displayed depending on the value of the
+.SM
+.B HISTTIMEFORMAT
+variable.
+When a shell with history enabled exits, the last
+.SM
+.B $HISTSIZE
+lines are copied from the history list to
+.SM
+.BR $HISTFILE .
+If the
+.B histappend
+shell option is enabled
+(see the description of
+.B shopt
+under
+.SM
+.B "SHELL BUILTIN COMMANDS"
+below), the lines are appended to the history file,
+otherwise the history file is overwritten.
+If
+.SM
+.B HISTFILE
+is unset, or if the history file is unwritable, the history is
+not saved.
+If the
+.SM
+.B HISTTIMEFORMAT
+variable is set, time stamps are written to the history file, marked
+with the history comment character, so
+they may be preserved across shell sessions.
+This uses the history comment character to distinguish timestamps from
+other history lines.
+After saving the history, the history file is truncated
+to contain no more than
+.SM
+.B HISTFILESIZE
+lines.  If
+.SM
+.B HISTFILESIZE
+is unset, or set to null, a non-numeric value,
+or a numeric value less than zero, the history file is not truncated.
+.PP
+The builtin command
+.B fc
+(see
+.SM
+.B SHELL BUILTIN COMMANDS
+below) may be used to list or edit and re-execute a portion of
+the history list.
+The
+.B history
+builtin may be used to display or modify the history list and
+manipulate the history file.
+When using command-line editing, search commands
+are available in each editing mode that provide access to the
+history list.
+.PP
+The shell allows control over which commands are saved on the history
+list.  The
+.SM
+.B HISTCONTROL
+and
+.SM
+.B HISTIGNORE
+variables may be set to cause the shell to save only a subset of the
+commands entered.
+The
+.B cmdhist
+shell option, if enabled, causes the shell to attempt to save each
+line of a multi-line command in the same history entry, adding
+semicolons where necessary to preserve syntactic correctness.
+The
+.B lithist
+shell option causes the shell to save the command with embedded newlines
+instead of semicolons.  See the description of the
+.B shopt
+builtin below under
+.SM
+.B "SHELL BUILTIN COMMANDS"
+for information on setting and unsetting shell options.
+.SH "HISTORY EXPANSION"
+The shell supports a history expansion feature that
+is similar to the history expansion in
+.BR csh .
+This section describes what syntax features are available.  This
+feature is enabled by default for interactive shells, and can be
+disabled using the
+.B +H
+option to the
+.B set
+builtin command (see
+.SM
+.B SHELL BUILTIN COMMANDS
+below).  Non-interactive shells do not perform history expansion
+by default.
+.PP
+History expansions introduce words from the history list into
+the input stream, making it easy to repeat commands, insert the
+arguments to a previous command into the current input line, or
+fix errors in previous commands quickly.
+.PP
+History expansion is performed immediately after a complete line
+is read, before the shell breaks it into words, and is performed
+on each line individually without taking quoting on previous lines into
+account.
+It takes place in two parts.
+The first is to determine which line from the history list
+to use during substitution.
+The second is to select portions of that line for inclusion into
+the current one.
+The line selected from the history is the \fIevent\fP,
+and the portions of that line that are acted upon are \fIwords\fP.
+Various \fImodifiers\fP are available to manipulate the selected words.
+The line is broken into words in the same fashion as when reading input,
+so that several \fImetacharacter\fP-separated words surrounded by
+quotes are considered one word.
+History expansions are introduced by the appearance of the
+history expansion character, which is \^\fB!\fP\^ by default.
+Only backslash (\^\fB\e\fP\^) and single quotes can quote
+the history expansion character, but the history expansion character is
+also treated as quoted if it immediately precedes the closing double quote
+in a double-quoted string.

+.SH "SHELL COMPATIBILITY MODE"
+Bash-4.0 introduced the concept of a \fIshell compatibility level\fP,
+specified as a set of options to the shopt builtin (
+.BR compat31 ,
+.BR compat32 ,
+.BR compat40 ,
+.BR compat41 ,
+and so on).
+There is only one current
+compatibility level -- each option is mutually exclusive.
+The compatibility level is intended to allow users to select behavior
+from previous versions that is incompatible with newer versions
+while they migrate scripts to use current features and
+behavior. It's intended to be a temporary solution.
+.PP
+This section does not mention behavior that is standard for a particular
+version (e.g., setting \fBcompat32\fP means that quoting the rhs of the regexp
+matching operator quotes special regexp characters in the word, which is
+default behavior in bash-3.2 and subsequent versions). 
+.PP
+If a user enables, say, \fBcompat32\fP, it may affect the behavior of other
+compatibility levels up to and including the current compatibility level.
+The idea is that each compatibility level controls behavior that changed
+in that version of \fBbash\fP,
+but that behavior may have been present in earlier versions.
+For instance, the change to use locale-based comparisons with the \fB[[\fP
+command came in bash-4.1, and earlier versions used ASCII-based comparisons,
+so enabling \fBcompat32\fP will enable ASCII-based comparisons as well.
+That granularity may not be sufficient for
+all uses, and as a result users should employ compatibility levels carefully.
+Read the documentation for a particular feature to find out the
+current behavior.
+.PP
+Bash-4.3 introduced a new shell variable:
+.SM
+.BR BASH_COMPAT .
+The value assigned
+to this variable (a decimal version number like 4.2, or an integer
+corresponding to the \fBcompat\fP\fINN\fP option, like 42) determines the
+compatibility level.
+.PP
+Starting with bash-4.4, Bash has begun deprecating older compatibility
+levels.
+Eventually, the options will be removed in favor of
+.SM
+.BR BASH_COMPAT .
+.PP
+Bash-5.0 is the final version for which there will be an individual shopt
+option for the previous version. Users should use
+.SM
+.B BASH_COMPAT
+on bash-5.0 and later versions.
+.PP
+The following table describes the behavior changes controlled by each
+compatibility level setting.
+The \fBcompat\fP\fINN\fP tag is used as shorthand for setting the
+compatibility level
+to \fINN\fP using one of the following mechanisms.
+For versions prior to bash-5.0, the compatibility level may be set using
+the corresponding \fBcompat\fP\fINN\fP shopt option.
+For bash-4.3 and later versions, the
+.SM
+.B BASH_COMPAT

+<A NAME="lbAE">&nbsp;</A>
+<H3>DESCRIPTION</H3>
+
+<B>Bash</B>
+
+is an <B>sh</B>-compatible command language interpreter that
+executes commands read from the standard input or from a file.
+<B>Bash</B>
+
+also incorporates useful features from the <I>Korn</I> and <I>C</I>
+shells (<B>ksh</B> and <B>csh</B>).
+<P>
+
+<B>Bash</B>
+
+is intended to be a conformant implementation of the
+Shell and Utilities portion of the IEEE POSIX specification
+(IEEE Standard 1003.1).
+<B>Bash</B>
+
+can be configured to be POSIX-conformant by default.
+<A NAME="lbAF">&nbsp;</A>
+<H3>OPTIONS</H3>
+
+All of the single-character shell options documented in the
+description of the <B>set</B> builtin command, including <B>-o</B>,
+can be used as options when the shell is invoked.
+In addition, <B>bash</B>
+interprets the following options when it is invoked:
+<P>
+
+
+<DL COMPACT>
+<DT><B>-c</B>
+
+<DD>
+If the
+<B>-c</B>
+
+option is present, then commands are read from the first non-option argument
+<I>command_string</I>.
+
+If there are arguments after the
+<I>command_string</I>,
+
+the first argument is assigned to
+<B>$0</B>
+
+and any remaining arguments are assigned to the positional parameters.
+The assignment to
+<B>$0</B>
+
+sets the name of the shell, which is used in warning and error messages.
+<DT><B>-i</B>
+
+<DD>
+If the
+<B>-i</B>
+
+option is present, the shell is
+<I>interactive</I>.
+
+<DT><B>-l</B>
+
+<DD>
+Make
+<B>bash</B>
+
+act as if it had been invoked as a login shell (see
+<FONT SIZE=-1><B>INVOCATION</B>
+
+</FONT>
+below).
+<DT><B>-r</B>
+
+<DD>
+If the
+<B>-r</B>
+
+option is present, the shell becomes
+<I>restricted</I>
+
+(see
+<FONT SIZE=-1><B>RESTRICTED SHELL</B>
+
+</FONT>
+below).
+<DT><B>-s</B>
+
+<DD>
+If the
+<B>-s</B>
+
+option is present, or if no arguments remain after option
+processing, then commands are read from the standard input.
+This option allows the positional parameters to be set
+when invoking an interactive shell or when reading input
+through a pipe.
+<DT><B>-D</B>
+
+<DD>
+A list of all double-quoted strings preceded by <B>$</B>
+is printed on the standard output.
+These are the strings that
+are subject to language translation when the current locale
+is not <B>C</B> or <B>POSIX</B>.
+This implies the <B>-n</B> option; no commands will be executed.
+<DT><B>[-+]O [</B><I>shopt_option</I>]
+
+<DD>
+<I>shopt_option</I> is one of the shell options accepted by the
+<B>shopt</B> builtin (see
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below).
+If <I>shopt_option</I> is present, <B>-O</B> sets the value of that option;
+<B>+O</B> unsets it.
+If <I>shopt_option</I> is not supplied, the names and values of the shell
+options accepted by <B>shopt</B> are printed on the standard output.
+If the invocation option is <B>+O</B>, the output is displayed in a format
+that may be reused as input.
+<DT><B>--</B>
+
+<DD>
+A
+<B>--</B>
+
+signals the end of options and disables further option processing.
+Any arguments after the
+<B>--</B>
+
+are treated as filenames and arguments.  An argument of
+<B>-</B>
+
+is equivalent to <B>--</B>.
+
+</DL>
+<P>
+
+<B>Bash</B>
+
+also interprets a number of multi-character options.
+These options must appear on the command line before the
+single-character options to be recognized.
+<P>
+
+
+<DL COMPACT>

+
+<DD>
+Arrange for the debugger profile to be executed before the shell

+<H3>ARGUMENTS</H3>
+
+If arguments remain after option processing, and neither the
+<B>-c</B>
+
+nor the
+<B>-s</B>
+
+option has been supplied, the first argument is assumed to
+be the name of a file containing shell commands.
+If
+<B>bash</B>
+
+is invoked in this fashion,
+<B>$0</B>
+
+is set to the name of the file, and the positional parameters
+are set to the remaining arguments.
+<B>Bash</B>
+
+reads and executes commands from this file, then exits.
+<B>Bash</B>'s exit status is the exit status of the last command
+executed in the script.
+If no commands are executed, the exit status is 0.
+An attempt is first made to open the file in the current directory, and,
+if no file is found, then the shell searches the directories in
+<FONT SIZE=-1><B>PATH</B>
+
+</FONT>
+for the script.

+
+A <I>login shell</I> is one whose first character of argument zero is a

+
+An <I>interactive</I> shell is one started without non-option arguments
+(unless <B>-s</B> is specified)
+and without the
+<B>-c</B>
+
+option,
+whose standard input and error are
+both connected to terminals (as determined by
+<I>isatty</I>(3)),
+
+or one started with the

+<B>$-</B>
+
+includes
+<B>i</B>
+
+if
+<B>bash</B>
+
+is interactive,
+allowing a shell script or a startup file to test this state.
+<P>
+
+The following paragraphs describe how
+<B>bash</B>
+
+executes its startup files.
+If any of the files exist but cannot be read,
+<B>bash</B>
+
+reports an error.
+Tildes are expanded in filenames as described below under
+<B>Tilde Expansion</B>
+
+in the
+<FONT SIZE=-1><B>EXPANSION</B>
+
+</FONT>
+section.
+<P>
+
+When
+<B>bash</B>
+
+is invoked as an interactive login shell, or as a non-interactive shell
+with the <B>--login</B> option, it first reads and
+executes commands from the file <A HREF="file:/etc/profile"><I>/etc/profile</I></A>, if that
+file exists.
+After reading that file, it looks for <A HREF="file:~/.bash_profile"><I>~/.bash_profile</I></A>,
+<A HREF="file:~/.bash_login"><I>~/.bash_login</I></A>, and <A HREF="file:~/.profile"><I>~/.profile</I></A>, in that order, and reads
+and executes commands from the first one that exists and is readable.
+The
+<B>--noprofile</B>
+
+option may be used when the shell is started to inhibit this behavior.
+<P>
+
+When an interactive login shell exits,
+or a non-interactive login shell executes the <B>exit</B> builtin command,
+<B>bash</B>
+
+reads and executes commands from the file <A HREF="file:~/.bash_logout"><I>~/.bash_logout</I></A>, if it
+exists.
+<P>
+
+When an interactive shell that is not a login shell is started,
+<B>bash</B>
+
+reads and executes commands from <A HREF="file:~/.bashrc"><I>~/.bashrc</I></A>, if that file exists.
+This may be inhibited by using the
+<B>--norc</B>
+
+option.
+The <B>--rcfile</B> <I>file</I> option will force
+<B>bash</B>
+
+to read and execute commands from <I>file</I> instead of <A HREF="file:~/.bashrc"><I>~/.bashrc</I></A>.
+<P>
+
+When
+<B>bash</B>
+
+is started non-interactively, to run a shell script, for example, it
+looks for the variable
+<FONT SIZE=-1><B>BASH_ENV</B>
+
+</FONT>
+in the environment, expands its value if it appears there, and uses the
+expanded value as the name of a file to read and execute.
+<B>Bash</B>
+
+behaves as if the following command were executed:
+<P>
+<DL COMPACT><DT><DD>
+<TT>if [ -n &quot;$BASH_ENV&quot; ]; then . &quot;$BASH_ENV&quot;; fi</TT>
+
+</DL>
+
+<P>
+but the value of the
+<FONT SIZE=-1><B>PATH</B>
+
+</FONT>
+variable is not used to search for the filename.
+<P>
+
+If
+<B>bash</B>
+
+is invoked with the name
+<B>sh</B>,
+
+it tries to mimic the startup behavior of historical versions of
+<B>sh</B>
+
+as closely as possible,
+while conforming to the POSIX standard as well.
+When invoked as an interactive login shell, or a non-interactive
+shell with the <B>--login</B> option, it first attempts to
+read and execute commands from
+<A HREF="file:/etc/profile"><I>/etc/profile</I></A>
+
+and
+<A HREF="file:~/.profile"><I>~/.profile</I></A>,
+
+in that order.
+The
+<B>--noprofile</B>
+
+option may be used to inhibit this behavior.
+When invoked as an interactive shell with the name
+<B>sh</B>,
+
+<B>bash</B>
+
+looks for the variable
+<FONT SIZE=-1><B>ENV</B>,
+
+</FONT>
+expands its value if it is defined, and uses the
+expanded value as the name of a file to read and execute.
+Since a shell invoked as
+<B>sh</B>
+
+does not attempt to read and execute commands from any other startup
+files, the
+<B>--rcfile</B>
+
+option has no effect.
+A non-interactive shell invoked with the name
+<B>sh</B>
+
+does not attempt to read any other startup files.
+When invoked as
+<B>sh</B>,
+
+<B>bash</B>
+
+enters
+<I>posix</I>
+
+mode after the startup files are read.
+<P>
+
+When
+<B>bash</B>
+
+is started in
+<I>posix</I>
+
+mode, as with the
+<B>--posix</B>
+
+command line option, it follows the POSIX standard for startup files.
+In this mode, interactive shells expand the
+<FONT SIZE=-1><B>ENV</B>
+
+</FONT>
+variable and commands are read and executed from the file
+whose name is the expanded value.
+No other startup files are read.
+<P>
+
+<B>Bash</B>
+
+attempts to determine when it is being run with its standard input
+connected to a network connection, as when executed by
+the historical remote shell daemon, usually <I>rshd</I>,
+or the secure shell daemon <I>sshd</I>.
+If
+<B>bash</B>
+
+determines it is being run non-interactively in this fashion,
+it reads and executes commands from <A HREF="file:~/.bashrc"><I>~/.bashrc</I></A>,
+if that file exists and is readable.
+It will not do this if invoked as <B>sh</B>.
+The
+<B>--norc</B>
+
+option may be used to inhibit this behavior, and the
+<B>--rcfile</B>
+
+option may be used to force another file to be read, but neither
+<I>rshd</I> nor <I>sshd</I> generally invoke the shell with those options
+or allow them to be specified.
+<P>
+
+If the shell is started with the effective user (group) id not equal to the
+real user (group) id, and the <B>-p</B> option is not supplied, no startup
+files are read, shell functions are not inherited from the environment, the

+<H3>SHELL GRAMMAR</H3>
+
+This section describes the syntax of the various forms of shell commands.
+<A NAME="lbAL">&nbsp;</A>
+<H4>Simple Commands</H4>
+
+A <I>simple command</I> is a sequence of optional variable assignments
+followed by <B>blank</B>-separated words and redirections, and
+terminated by a <I>control operator</I>.  The first word
+specifies the command to be executed, and is passed as argument zero.
+The remaining words are passed as arguments to the invoked command.
+<P>
+
+The return value of a <I>simple command</I> is its exit status, or
+128+<I>n</I> if the command is terminated by signal
+<I>n</I>.
+
+<A NAME="lbAM">&nbsp;</A>
+<H4>Pipelines</H4>
+
+A <I>pipeline</I> is a sequence of one or more commands separated by
+one of the control operators
+<B>|</B>
+
+or <B>|&amp;</B>.
+The format for a pipeline is:
+<DL COMPACT><DT><DD>
+<P>
+
+[<B>time</B> [<B>-p</B>]] [ ! ] <I>command1</I> [ [<B>|</B>|<B>|&amp;</B>] <I>command2</I> ... ]
+</DL>
+
+<P>
+
+The standard output of
+<I>command1</I>
+
+is connected via a pipe to the standard input of
+<I>command2</I>.
+
+This connection is performed before any redirections specified by the
+<I>command1</I>(see
+
+<FONT SIZE=-1><B>REDIRECTION</B>
+
+</FONT>
+below).
+If <B>|&amp;</B> is used, <I>command1</I>'s standard error, in addition to its
+standard output, is connected to
+<I>command2</I>'s standard input through the pipe;
+it is shorthand for <B>2&gt;&amp;1 |</B>.
+This implicit redirection of the standard error to the standard output is
+performed after any redirections specified by <I>command1</I>.
+<P>
+
+The return status of a pipeline is the exit status of the last
+command, unless the <B>pipefail</B> option is enabled.
+If <B>pipefail</B> is enabled, the pipeline's return status is the
+value of the last (rightmost) command to exit with a non-zero status,
+or zero if all commands exit successfully.
+If the reserved word
+<B>!</B>
+
+precedes a pipeline, the exit status of that pipeline is the logical
+negation of the exit status as described above.
+The shell waits for all commands in the pipeline to
+terminate before returning a value.
+<P>
+
+If the
+<B>time</B>
+
+reserved word precedes a pipeline, the elapsed as well as user and
+system time consumed by its execution are reported when the pipeline
+terminates.
+The <B>-p</B> option changes the output format to that specified by POSIX.
+When the shell is in <I>posix mode</I>, it does not recognize
+<B>time</B> as a reserved word if the next token begins with a `-'.
+The
+<FONT SIZE=-1><B>TIMEFORMAT</B>
+
+</FONT>
+variable may be set to a format string that specifies how the timing
+information should be displayed; see the description of
+<FONT SIZE=-1><B>TIMEFORMAT</B>
+
+</FONT>
+under
+<B>Shell Variables</B>
+
+below.
+<P>
+
+When the shell is in <I>posix mode</I>, <B>time</B>
+may be followed by a newline.  In this case, the shell displays the
+total user and system time consumed by the shell and its children.
+The
+<FONT SIZE=-1><B>TIMEFORMAT</B>
+
+</FONT>
+variable may be used to specify the format of
+the time information.
+<P>
+
+Each command in a multi-command pipeline,
+where pipes are created,
+is executed in a <I>subshell</I>, which is a
+separate process.
+See
+<FONT SIZE=-1><B>COMMAND EXECUTION ENVIRONMENT</B></FONT>
+for a description of subshells and a subshell environment.
+If the <B>lastpipe</B> option is enabled using the <B>shopt</B> builtin
+(see the description of <B>shopt</B> below),
+the last element of a pipeline may be run by the shell process
+when job control is not active.
+<A NAME="lbAN">&nbsp;</A>
+<H4>Lists</H4>
+
+A <I>list</I> is a sequence of one or more pipelines separated by one
+of the operators
+<B>;</B>,
+
+<B>&amp;</B>,
+
+<B>&amp;&amp;</B>,
+
+or
+<B>||</B>,
+
+and optionally terminated by one of
+<B>;</B>,
+
+<B>&amp;</B>,
+
+or
+<B>&lt;newline&gt;</B>.
+
+<P>
+
+Of these list operators,
+<B>&amp;&amp;</B>
+
+and
+<B>||</B>
+
+have equal precedence, followed by
+<B>;</B>
+
+and
+<B>&amp;</B>,
+
+which have equal precedence.
+<P>
+
+A sequence of one or more newlines may appear in a <I>list</I> instead
+of a semicolon to delimit commands.
+<P>
+
+If a command is terminated by the control operator
+<B>&amp;</B>,
+
+the shell executes the command in the <I>background</I>
+in a subshell.
+The shell does not wait for the command to
+finish, and the return status is 0.
+These are referred to as <I>asynchronous</I> commands.
+Commands separated by a
+<B>;</B>
+
+are executed sequentially; the shell waits for each
+command to terminate in turn.  The return status is the
+exit status of the last command executed.
+<P>
+
+AND and OR lists are sequences of one or more pipelines separated by the
+<B>&amp;&amp;</B> and <B>||</B> control operators, respectively.
+AND and OR lists are executed with left associativity.
+An AND list has the form
+<DL COMPACT><DT><DD>
+<P>
+
+<I>command1</I> <B>&amp;&amp;</B> <I>command2</I>
+</DL>
+
+<P>
+
+<I>command2</I>
+
+is executed if, and only if,
+<I>command1</I>
+
+returns an exit status of zero (success).
+<P>
+
+An OR list has the form
+<DL COMPACT><DT><DD>
+<P>
+
+<I>command1</I> <B>||</B> <I>command2</I>
+</DL>
+
+<P>
+
+<I>command2</I>
+
+is executed if, and only if,
+<I>command1</I>
+
+returns a non-zero exit status.
+The return status of
+AND and OR lists is the exit status of the last command
+executed in the list.
+<A NAME="lbAO">&nbsp;</A>
+<H4>Compound Commands</H4>
+
+A <I>compound command</I> is one of the following.
+In most cases a <I>list</I> in a command's description may be separated from
+the rest of the command by one or more newlines, and may be followed by a
+newline in place of a semicolon.
+<DL COMPACT>
+<DT>(<I>list</I>)<DD>
+<I>list</I> is executed in a subshell (see
+<FONT SIZE=-1><B>COMMAND EXECUTION ENVIRONMENT</B></FONT>
+below for a description of a subshell environment).
+Variable assignments and builtin
+commands that affect the shell's environment do not remain in effect
+after the command completes.  The return status is the exit status of
+<I>list</I>.
+<DT>{ <I>list</I>; }<DD>
+<I>list</I> is simply executed in the current shell environment.
+<I>list</I> must be terminated with a newline or semicolon.
+This is known as a <I>group command</I>.
+The return status is the exit status of
+<I>list</I>.
+Note that unlike the metacharacters <B>(</B> and <B>)</B>, <B>{</B> and
+<B>}</B> are <I>reserved words</I> and must occur where a reserved
+word is permitted to be recognized.  Since they do not cause a word
+break, they must be separated from <I>list</I> by whitespace or another
+shell metacharacter.
+<DT>((<I>expression</I>))<DD>
+The <I>expression</I> is evaluated according to the rules described
+below under
+<FONT SIZE=-1><B>ARITHMETIC EVALUATION</B>.
+
+</FONT>
+If the value of the expression is non-zero, the return status is 0;
+otherwise the return status is 1.
+The <I>expression</I>
+undergoes the same expansions
+as if it were within double quotes,
+but double quote characters in <I>expression</I> are not treated specially
+and are removed.
+<DT><B>[[</B> <I>expression</I> <B>]]</B><DD>
+Return a status of 0 or 1 depending on the evaluation of
+the conditional expression <I>expression</I>.
+Expressions are composed of the primaries described below under
+<FONT SIZE=-1><B>CONDITIONAL EXPRESSIONS</B>.
+
+</FONT>
+The words between the <B>[[</B> and <B>]]</B> do not undergo word splitting
+and pathname expansion.
+The shell performs tilde expansion, parameter and
+variable expansion, arithmetic expansion, command substitution, process
+substitution, and quote removal on those words
+(the expansions that would occur if the words were enclosed in double quotes).
+Conditional operators such as <B>-f</B> must be unquoted to be recognized
+as primaries.
+<P>
+
+
+When used with <B>[[</B>, the <B>&lt;</B> and <B>&gt;</B> operators sort
+lexicographically using the current locale.
+<P>
+
+
+When the <B>==</B> and <B>!=</B> operators are used, the string to the
+right of the operator is considered a pattern and matched according
+to the rules described below under <B>Pattern Matching</B>,
+as if the <B>extglob</B> shell option were enabled.
+The <B>=</B> operator is equivalent to <B>==</B>.
+If the
+<B>nocasematch</B>
+
+shell option is enabled, the match is performed without regard to the case
+of alphabetic characters.
+The return value is 0 if the string matches (<B>==</B>) or does not match
+(<B>!=</B>) the pattern, and 1 otherwise.
+Any part of the pattern may be quoted to force the quoted portion
+to be matched as a string.
+<P>
+
+
+An additional binary operator, <B>=~</B>, is available, with the same
+precedence as <B>==</B> and <B>!=</B>.
+When it is used, the string to the right of the operator is considered
+a POSIX extended regular expression and matched accordingly
+(using the POSIX <I>regcomp</I> and <I>regexec</I> interfaces
+usually described in <I>regex</I>(3)).
+The return value is 0 if the string matches
+the pattern, and 1 otherwise.
+If the regular expression is syntactically incorrect, the conditional
+expression's return value is 2.
+If the
+<B>nocasematch</B>
+
+shell option is enabled, the match is performed without regard to the case
+of alphabetic characters.
+If any part of the pattern is quoted, the quoted portion is matched literally.
+This means every character in the quoted portion matches itself,
+instead of having any special pattern matching meaning.
+If the pattern is stored in a shell variable, quoting the variable
+expansion forces the entire pattern to be matched literally.
+Treat bracket expressions in regular expressions carefully,
+since normal quoting and pattern characters lose their meanings
+between brackets.
+<P>
+
+
+The pattern will match if it matches any part of the string.
+Anchor the pattern using the <B>^</B> and <B>$</B> regular expression
+operators to force it to match the entire string.
+The array variable
+<FONT SIZE=-1><B>BASH_REMATCH</B>
+
+</FONT>
+records which parts of the string matched the pattern.
+The element of
+<FONT SIZE=-1><B>BASH_REMATCH</B>
+
+</FONT>
+with index 0 contains the portion of
+the string matching the entire regular expression.
+Substrings matched by parenthesized subexpressions within the regular
+expression are saved in the remaining
+<FONT SIZE=-1><B>BASH_REMATCH</B>
+
+</FONT>
+indices. The element of
+<FONT SIZE=-1><B>BASH_REMATCH</B>
+
+</FONT>
+with index <I>n</I> is the portion of the
+string matching the <I>n</I>th parenthesized subexpression.
+Bash sets
+<FONT SIZE=-1><B>BASH_REMATCH</B>
+
+</FONT>
+in the global scope; declaring it as a local variable will lead to
+unexpected results.
+<P>
+
+
+Expressions may be combined using the following operators, listed
+in decreasing order of precedence:
+<P>
+
+
+<DL COMPACT><DT><DD>
+
+<DL COMPACT>
+<DT><B>( </B><I>expression</I> )
+
+<DD>
+Returns the value of <I>expression</I>.
+This may be used to override the normal precedence of operators.
+<DT><B>! </B><I>expression</I>
+
+<DD>
+True if
+<I>expression</I>
+
+is false.
+<DT><I>expression1</I> <B>&amp;&amp;</B> <I>expression2</I><DD>
+True if both
+<I>expression1</I>
+
+and
+<I>expression2</I>
+
+are true.
+<DT><I>expression1</I> <B>||</B> <I>expression2</I><DD>
+True if either
+<I>expression1</I>
+
+or
+<I>expression2</I>
+
+is true.
+
+</DL>
+<P>
+
+The <B>&amp;&amp;</B> and <B>||</B>
+operators do not evaluate <I>expression2</I> if the value of
+<I>expression1</I> is sufficient to determine the return value of
+the entire conditional expression.
+</DL>
+
+<DT><B>for</B> <I>name</I> [ [ <B>in</B> [ <I>word ...</I> ] ] ; ] <B>do</B> <I>list</I> ; <B>done</B><DD>
+The list of words following <B>in</B> is expanded, generating a list
+of items.
+The variable <I>name</I> is set to each element of this list
+in turn, and <I>list</I> is executed each time.
+If the <B>in</B> <I>word</I> is omitted, the <B>for</B> command executes
+<I>list</I> once for each positional parameter that is set (see
+<FONT SIZE=-1><B>PARAMETERS</B>
+
+</FONT>
+below).
+The return status is the exit status of the last command that executes.
+If the expansion of the items following <B>in</B> results in an empty
+list, no commands are executed, and the return status is 0.
+<DT><B>for</B> (( <I>expr1</I> ; <I>expr2</I> ; <I>expr3</I> )) ; <B>do</B> <I>list</I> ; <B>done</B><DD>
+First, the arithmetic expression <I>expr1</I> is evaluated according
+to the rules described below under
+<FONT SIZE=-1><B>ARITHMETIC EVALUATION</B>.
+
+</FONT>
+The arithmetic expression <I>expr2</I> is then evaluated repeatedly
+until it evaluates to zero.
+Each time <I>expr2</I> evaluates to a non-zero value, <I>list</I> is
+executed and the arithmetic expression <I>expr3</I> is evaluated.
+If any expression is omitted, it behaves as if it evaluates to 1.
+The return value is the exit status of the last command in <I>list</I>
+that is executed, or false if any of the expressions is invalid.
+<DT><B>select</B> <I>name</I> [ <B>in</B> <I>word</I> ] ; <B>do</B> <I>list</I> ; <B>done</B><DD>
+The list of words following <B>in</B> is expanded, generating a list
+of items, and the set of expanded words is printed on the standard
+error, each preceded by a number.  If the <B>in</B>
+<I>word</I> is omitted, the positional parameters are printed (see
+<FONT SIZE=-1><B>PARAMETERS</B>
+
+</FONT>
+below).
+<B>select</B>
+
+then displays the
+<FONT SIZE=-1><B>PS3</B>
+
+</FONT>
+prompt and reads a line from the standard input.
+If the line consists of a number corresponding to one of
+the displayed words, then the value of
+<I>name</I>
+
+is set to that word.
+If the line is empty, the words and prompt are displayed again.
+If EOF is read, the <B>select</B> command completes and returns 1.
+Any other value read causes
+<I>name</I>
+
+to be set to null.  The line read is saved in the variable
+<FONT SIZE=-1><B>REPLY</B>.
+
+</FONT>
+The
+<I>list</I>
+
+is executed after each selection until a
+<B>break</B>
+
+command is executed.
+The exit status of
+<B>select</B>
+
+is the exit status of the last command executed in
+<I>list</I>,
+
+or zero if no commands were executed.
+<DT><B>case</B> <I>word</I> <B>in</B> [ [(] <I>pattern</I> [ <B>|</B> <I>pattern</I> ] 
+<DD>
+A <B>case</B> command first expands <I>word</I>, and tries to match
+it against each <I>pattern</I> in turn, using the matching rules
+described under
+<B>Pattern Matching</B>
+
+below.
+The <I>word</I> is expanded using tilde
+expansion, parameter and variable expansion, arithmetic expansion,
+command substitution, process substitution and quote removal.
+Each <I>pattern</I> examined is expanded using tilde
+expansion, parameter and variable expansion, arithmetic expansion,
+command substitution, process substitution, and quote removal.
+If the
+<B>nocasematch</B>
+
+shell option is enabled, the match is performed without regard to the case
+of alphabetic characters.
+When a match is found, the corresponding <I>list</I> is executed.
+If the <B>;;</B> operator is used, no subsequent matches are attempted after
+the first pattern match.
+Using <B>;&amp;</B> in place of <B>;;</B> causes execution to continue with
+the <I>list</I> associated with the next set of patterns.
+Using <B>;;&amp;</B> in place of <B>;;</B> causes the shell to test the next
+pattern list in the statement, if any, and execute any associated <I>list</I>
+on a successful match,
+continuing the case statement execution as if the pattern list had not matched.
+The exit status is zero if no
+pattern matches.  Otherwise, it is the exit status of the
+last command executed in <I>list</I>.
+<DT><B>if</B> <I>list</I>; <B>then</B> <I>list</I>; [ <B>elif</B> <I>list</I>; <B>then</B> <I>list</I>; ] ... [ <B>else</B> <I>list</I>; ] <B>fi</B><DD>
+The
+<B>if</B>
+
+<I>list</I>
+
+is executed.  If its exit status is zero, the
+<B>then</B> <I>list</I> is executed.  Otherwise, each <B>elif</B>
+<I>list</I> is executed in turn, and if its exit status is zero,
+the corresponding <B>then</B> <I>list</I> is executed and the
+command completes.  Otherwise, the <B>else</B> <I>list</I> is
+executed, if present.  The exit status is the exit status of the
+last command executed, or zero if no condition tested true.
+<DT><B>while</B> <I>list-1</I>; <B>do</B> <I>list-2</I>; <B>done</B><DD>
+
+<DT><B>until</B> <I>list-1</I>; <B>do</B> <I>list-2</I>; <B>done</B><DD>
+
+The <B>while</B> command continuously executes the list
+<I>list-2</I> as long as the last command in the list <I>list-1</I> returns
+an exit status of zero.  The <B>until</B> command is identical
+to the <B>while</B> command, except that the test is negated:
+<I>list-2</I>
+
+is executed as long as the last command in
+<I>list-1</I>
+
+returns a non-zero exit status.
+The exit status of the <B>while</B> and <B>until</B> commands
+is the exit status
+of the last command executed in <I>list-2</I>, or zero if
+none was executed.
+</DL>
+<A NAME="lbAP">&nbsp;</A>
+<H4>Coprocesses</H4>
+
+A <I>coprocess</I> is a shell command preceded by the <B>coproc</B> reserved
+word.
+A coprocess is executed asynchronously in a subshell, as if the command
+had been terminated with the <B>&amp;</B> control operator, with a two-way pipe
+established between the executing shell and the coprocess.
+<P>
+
+The syntax for a coprocess is:
+<DL COMPACT><DT><DD>
+<P>
+
+<B>coproc</B> [<I>NAME</I>] <I>command</I> [<I>redirections</I>]
+</DL>
+
+<P>
+
+This creates a coprocess named <I>NAME</I>.
+<I>command</I> may be either a simple command or a compound
+command (see above).
+<I>NAME</I> is a shell variable name.
+If <I>NAME</I> is not supplied, the default name is <B>COPROC</B>.
+<P>
+
+The recommended form to use for a coprocess is
+<DL COMPACT><DT><DD>
+<P>
+
+<B>coproc</B> <I>NAME</I> { <I>command</I> [<I>redirections</I>]; }
+</DL>
+
+<P>
+
+This form is recommended because simple commands result in the coprocess
+always being named <B>COPROC</B>, and it is simpler to use and more complete
+than the other compound commands.
+<P>
+
+If <I>command</I> is a compound command, <I>NAME</I> is optional. The
+word following <B>coproc</B> determines whether that word is interpreted
+as a variable name: it is interpreted as <I>NAME</I> if it is not a
+reserved word that introduces a compound command.
+If <I>command</I> is a simple command, <I>NAME</I> is not allowed; this
+is to avoid confusion between <I>NAME</I> and the first word of the simple
+command.
+<P>
+
+When the coprocess is executed, the shell creates an array variable (see
+<B>Arrays</B>
+
+below) named <I>NAME</I> in the context of the executing shell.
+The standard output of
+<I>command</I>
+
+is connected via a pipe to a file descriptor in the executing shell,
+and that file descriptor is assigned to <I>NAME</I>[0].
+The standard input of
+<I>command</I>
+
+is connected via a pipe to a file descriptor in the executing shell,
+and that file descriptor is assigned to <I>NAME</I>[1].
+This pipe is established before any redirections specified by the
+command (see
+<FONT SIZE=-1><B>REDIRECTION</B>
+
+</FONT>
+below).
+The file descriptors can be utilized as arguments to shell commands

+<H4>Shell Function Definitions</H4>
+
+A shell function is an object that is called like a simple command and
+executes a compound command with a new set of positional parameters.
+Shell functions are declared as follows:
+<DL COMPACT>
+<DT><I>fname</I> () <I>compound-command</I> [<I>redirection</I>]<DD>
+
+<DT><B>function</B> <I>fname</I> [()] <I>compound-command</I> [<I>redirection</I>]<DD>
+
+This defines a function named <I>fname</I>.
+The reserved word <B>function</B> is optional.
+If the <B>function</B> reserved word is supplied, the parentheses are optional.
+The <I>body</I> of the function is the compound command
+<I>compound-command</I>
+
+(see <B>Compound Commands</B> above).
+That command is usually a <I>list</I> of commands between { and }, but
+may be any command listed under <B>Compound Commands</B> above.
+If the <B>function</B> reserved word is used, but the
+parentheses are not supplied, the braces are recommended.
+<I>compound-command</I> is executed whenever <I>fname</I> is specified as the
+name of a simple command.
+When in <I>posix mode</I>, <I>fname</I> must be a valid shell <I>name</I>
+and may not be the name of one of the
+POSIX <I>special builtins</I>.
+In default mode, a function name can be any unquoted shell word that does
+not contain <B>$</B>.
+Any redirections (see
+<FONT SIZE=-1><B>REDIRECTION</B>
+
+</FONT>
+below) specified when a function is defined are performed
+when the function is executed.
+The exit status of a function definition is zero unless a syntax error
+occurs or a readonly function with the same name already exists.
+When executed, the exit status of a function is the exit status of the
+last command executed in the body.  (See
+<FONT SIZE=-1><B>FUNCTIONS</B>
+
+</FONT>
+below.)
+</DL>
+<A NAME="lbAR">&nbsp;</A>
+<H3>COMMENTS</H3>
+
+In a non-interactive shell, or an interactive shell in which the
+<B>interactive_comments</B>
+
+option to the
+<B>shopt</B>
+
+builtin is enabled (see
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below), a word beginning with
+<B>#</B>
+
+causes that word and all remaining characters on that line to
+be ignored.  An interactive shell without the
+<B>interactive_comments</B>
+
+option enabled does not allow comments.  The
+<B>interactive_comments</B>
+
+option is on by default in interactive shells.
+<A NAME="lbAS">&nbsp;</A>
+<H3>QUOTING</H3>
+
+<I>Quoting</I> is used to remove the special meaning of certain
+characters or words to the shell.  Quoting can be used to
+disable special treatment for special characters, to prevent
+reserved words from being recognized as such, and to prevent
+parameter expansion.
+<P>
+
+Each of the <I>metacharacters</I> listed above under
+<FONT SIZE=-1><B>DEFINITIONS</B>
+
+</FONT>
+has special meaning to the shell and must be quoted if it is to
+represent itself.
+<P>
+
+When the command history expansion facilities are being used
+(see
+<FONT SIZE=-1><B>HISTORY EXPANSION</B>
+
+</FONT>
+below), the
+<I>history expansion</I> character, usually <B>!</B>, must be quoted
+to prevent history expansion.
+<P>
+
+There are three quoting mechanisms: the
+<I>escape character</I>,
+
+single quotes, and double quotes.
+<P>
+
+A non-quoted backslash (<B>\</B>) is the
+<I>escape character</I>.
+
+It preserves the literal value of the next character that follows,
+with the exception of &lt;newline&gt;.  If a <B>\</B>&lt;newline&gt; pair
+appears, and the backslash is not itself quoted, the <B>\</B>&lt;newline&gt;
+is treated as a line continuation (that is, it is removed from the
+input stream and effectively ignored).
+<P>
+
+Enclosing characters in single quotes preserves the literal value
+of each character within the quotes.  A single quote may not occur
+between single quotes, even when preceded by a backslash.
+<P>
+
+Enclosing characters in double quotes preserves the literal value
+of all characters within the quotes, with the exception of
+<B>$</B>,
+
+<B>`</B>,
+
+<B>\</B>,
+
+and, when history expansion is enabled,
+<B>!</B>.
+
+When the shell is in <I>posix mode</I>, the <B>!</B> has no special meaning
+within double quotes, even when history expansion is enabled.
+The characters
+<B>$</B>
+
+and
+<B>`</B>
+
+retain their special meaning within double quotes.  The backslash
+retains its special meaning only when followed by one of the following
+characters:
+<B>$</B>,
+
+<B>`</B>,
+
+<B>&quot;</B>,
+<B>\</B>,
+
+or
+<B>&lt;newline&gt;</B>.
+
+A double quote may be quoted within double quotes by preceding it with
+a backslash.
+If enabled, history expansion will be performed unless an
+<B>!</B>
+
+appearing in double quotes is escaped using a backslash.
+The backslash preceding the
+<B>!</B>
+
+is not removed.
+<P>
+
+The special parameters
+<B>*</B>
+
+and
+<B>@</B>
+
+have special meaning when in double
+quotes (see
+<FONT SIZE=-1><B>PARAMETERS</B>
+
+</FONT>
+below).
+<P>
+
+Character sequences of the form <B>$</B>aq<I>string</I>aq are treated
+as a special variant of single quotes.
+The sequence expands to <I>string</I>, with backslash-escaped characters
+in <I>string</I> replaced as specified by the ANSI C standard.
+Backslash escape sequences, if present, are decoded as follows:
+<DL COMPACT><DT><DD>
+

+alert (bell)

+<P>
+
+The expanded result is single-quoted, as if the dollar sign had
+not been present.
+<P>
+
+A double-quoted string preceded by a dollar sign (<B>$</B>dq<I>string</I>dq)
+will cause the string to be translated according to the current locale.
+The <I>gettext</I> infrastructure performs the lookup and
+translation, using the <B>LC_MESSAGES</B>, <B>TEXTDOMAINDIR</B>,
+and <B>TEXTDOMAIN</B> shell variables.
+If the current locale is <B>C</B> or <B>POSIX</B>,
+if there are no translations available,
+or if the string is not translated,
+the dollar sign is ignored.
+This is a form of double quoting, so the string remains double-quoted
+by default, whether or not it is translated and replaced.
+If the <B>noexpand_translation</B> option is enabled
+using the <B>shopt</B> builtin,
+translated strings are single-quoted instead of double-quoted.

+<H3>PARAMETERS</H3>
+
+A
+<I>parameter</I>
+
+is an entity that stores values.
+It can be a
+<I>name</I>,
+
+a number, or one of the special characters listed below under
+<B>Special Parameters</B>.
+
+A
+<I>variable</I>
+
+is a parameter denoted by a
+<I>name</I>.
+
+A variable has a <I>value</I> and zero or more <I>attributes</I>.
+Attributes are assigned using the
+<B>declare</B>
+
+builtin command (see
+<B>declare</B>
+
+below in
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>).
+
+</FONT>
+<P>
+
+A parameter is set if it has been assigned a value.  The null string is
+a valid value.  Once a variable is set, it may be unset only by using
+the
+<B>unset</B>
+
+builtin command (see
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below).
+<P>
+
+A
+<I>variable</I>
+
+may be assigned to by a statement of the form
+<DL COMPACT><DT><DD>
+<P>
+
+<I>name</I>=[<I>value</I>]
+</DL>
+
+<P>
+
+If
+<I>value</I>
+
+is not given, the variable is assigned the null string.  All
+<I>values</I>
+
+undergo tilde expansion, parameter and variable expansion,
+command substitution, arithmetic expansion, and quote
+removal (see
+<FONT SIZE=-1><B>EXPANSION</B>
+
+</FONT>
+below).  If the variable has its
+<B>integer</B>
+
+attribute set, then
+<I>value</I>
+
+is evaluated as an arithmetic expression even if the $((...)) expansion is
+not used (see
+<B>Arithmetic Expansion</B>
+
+below).
+Word splitting and pathname expansion are not performed.
+Assignment statements may also appear as arguments to the
+<B>alias</B>,
+
+<B>declare</B>,
+
+<B>typeset</B>,
+
+<B>export</B>,
+
+<B>readonly</B>,
+
+and
+<B>local</B>
+
+builtin commands (<I>declaration</I> commands).
+When in <I>posix mode</I>, these builtins may appear in a command after
+one or more instances of the <B>command</B> builtin and retain these
+assignment statement properties.
+<P>
+
+In the context where an assignment statement is assigning a value
+to a shell variable or array index, the += operator can be used to
+append to or add to the variable's previous value.
+This includes arguments to builtin commands such as <B>declare</B> that
+accept assignment statements (<I>declaration</I> commands).
+When += is applied to a variable for which the <B>integer</B> attribute has been
+set, <I>value</I> is evaluated as an arithmetic expression and added to the
+variable's current value, which is also evaluated.
+When += is applied to an array variable using compound assignment (see
+<B>Arrays</B>
+
+below), the
+variable's value is not unset (as it is when using =), and new values are
+appended to the array beginning at one greater than the array's maximum index
+(for indexed arrays) or added as additional key-value pairs in an
+associative array.
+When applied to a string-valued variable, <I>value</I> is expanded and
+appended to the variable's value.
+<P>
+
+A variable can be assigned the <I>nameref</I> attribute using the
+<B>-n</B> option to the <B>declare</B> or <B>local</B> builtin commands
+(see the descriptions of <B>declare</B> and <B>local</B> below)
+to create a <I>nameref</I>, or a reference to another variable.
+This allows variables to be manipulated indirectly.
+Whenever the nameref variable is referenced, assigned to, unset, or has
+its attributes modified (other than using or changing the <I>nameref</I>
+attribute itself), the
+operation is actually performed on the variable specified by the nameref
+variable's value.
+A nameref is commonly used within shell functions to refer to a variable
+whose name is passed as an argument to the function.
+For instance, if a variable name is passed to a shell function as its first
+argument, running
+<P>
+<DL COMPACT><DT><DD>
+<TT>declare -n ref=$1</TT>
+
+</DL>
+
+<P>
+inside the function creates a nameref variable <B>ref</B> whose value is
+the variable name passed as the first argument.
+References and assignments to <B>ref</B>, and changes to its attributes,
+are treated as references, assignments, and attribute modifications
+to the variable whose name was passed as <B>$1</B>.
+If the control variable in a <B>for</B> loop has the nameref attribute,
+the list of words can be a list of shell variables, and a name reference
+will be established for each word in the list, in turn, when the loop is
+executed.
+Array variables cannot be given the <B>nameref</B> attribute.
+However, nameref variables can reference array variables and subscripted
+array variables.
+Namerefs can be unset using the <B>-n</B> option to the <B>unset</B> builtin.
+Otherwise, if <B>unset</B> is executed with the name of a nameref variable
+as an argument, the variable referenced by the nameref variable will be unset.
+<A NAME="lbAU">&nbsp;</A>
+<H4>Positional Parameters</H4>
+
+A
+<I>positional parameter</I>
+
+is a parameter denoted by one or more
+digits, other than the single digit 0.  Positional parameters are
+assigned from the shell's arguments when it is invoked,
+and may be reassigned using the
+<B>set</B>
+
+builtin command.  Positional parameters may not be assigned to
+with assignment statements.  The positional parameters are
+temporarily replaced when a shell function is executed (see
+<FONT SIZE=-1><B>FUNCTIONS</B>
+
+</FONT>
+below).
+<P>
+
+When a positional parameter consisting of more than a single
+digit is expanded, it must be enclosed in braces (see
+<FONT SIZE=-1><B>EXPANSION</B>
+
+</FONT>
+below).
+<A NAME="lbAV">&nbsp;</A>
+<H4>Special Parameters</H4>
+
+The shell treats several parameters specially.  These parameters may
+only be referenced; assignment to them is not allowed.
+
+<DL COMPACT>
+<DT><B>*</B>
+
+<DD>
+Expands to the positional parameters, starting from one.
+When the expansion is not within double quotes, each positional parameter
+expands to a separate word.
+In contexts where it is performed, those words
+are subject to further word splitting and pathname expansion.
+When the expansion occurs within double quotes, it expands to a single word
+with the value of each parameter separated by the first character of the
+<FONT SIZE=-1><B>IFS</B>
+
+</FONT>
+special variable.  That is, &quot;<B>$*</B>&quot; is equivalent
+to &quot;<B>$1</B><I>c</I><B>$2</B><I>c</I><B>...</B>&quot;, where
+<I>c</I>
+
+is the first character of the value of the
+<FONT SIZE=-1><B>IFS</B>
+
+</FONT>
+variable.  If
+<FONT SIZE=-1><B>IFS</B>
+
+</FONT>
+is unset, the parameters are separated by spaces.
+If
+<FONT SIZE=-1><B>IFS</B>
+
+</FONT>
+is null, the parameters are joined without intervening separators.
+<DT><B>@</B>
+
+<DD>
+Expands to the positional parameters, starting from one.
+In contexts where word splitting is performed, this expands each
+positional parameter to a separate word; if not within double
+quotes, these words are subject to word splitting.
+In contexts where word splitting is not performed,
+this expands to a single word
+with each positional parameter separated by a space.
+When the
+expansion occurs within double quotes, each parameter expands to a
+separate word.  That is, &quot;<B>$@</B>&quot; is equivalent to
+&quot;<B>$1</B>&quot; &quot;<B>$2</B>&quot; ...
+If the double-quoted expansion occurs within a word, the expansion of
+the first parameter is joined with the beginning part of the original
+word, and the expansion of the last parameter is joined with the last
+part of the original word.
+When there are no positional parameters, &quot;<B>$@</B>&quot; and
+<B>$@</B>
+
+expand to nothing (i.e., they are removed).
+<DT><B>#</B>
+

+(such as the
+<B>-i</B>
+
+option).
+<DT><B>$</B>
+

+Expands to the process ID of the shell. In a subshell, it

+Expands to the process ID of the job most recently placed into the

+<B>$0</B>
+
+is set to the name of that file.  If

+
+<DD>
+An array variable (see <B>Arrays</B> below) created to hold the file descriptors
+for output from and input to an unnamed coprocess (see <B>Coprocesses</B>
+above).
+<DT><B>DIRSTACK</B>
+
+<DD>
+An array variable (see
+<B>Arrays</B>
+
+below) containing the current contents of the directory stack.
+Directories appear in the stack in the order they are displayed by the
+<B>dirs</B>
+

+<B>popd</B>
+
+builtins must be used to add and remove directories.
+Assignment to this variable will not change the current directory.
+If
+<FONT SIZE=-1><B>DIRSTACK</B>
+
+</FONT>
+is unset, it loses its special properties, even if it is
+subsequently reset.
+<DT><B>EPOCHREALTIME</B>
+
+<DD>
+Each time this parameter is referenced, it expands to the number of seconds
+since the Unix Epoch (see <I>time</I>(3)) as a floating point value
+with micro-second granularity.
+Assignments to
+<FONT SIZE=-1><B>EPOCHREALTIME</B>
+

+
+This variable exists only when a shell function is executing.
+Assignments to
+<FONT SIZE=-1><B>FUNCNAME</B>
+
+</FONT>
+have no effect.
+If
+<FONT SIZE=-1><B>FUNCNAME</B>
+
+</FONT>
+is unset, it loses its special properties, even if it is
+subsequently reset.
+<P>
+
+
+This variable can be used with <B>BASH_LINENO</B> and <B>BASH_SOURCE</B>.
+Each element of <B>FUNCNAME</B> has corresponding elements in
+<B>BASH_LINENO</B> and <B>BASH_SOURCE</B> to describe the call stack.
+For instance, <B>${FUNCNAME[</B><I>$i</I><B>]}</B> was called from the file
+<B>${BASH_SOURCE[</B><I>$i+1</I><B>]}</B> at line number
+<B>${BASH_LINENO[</B><I>$i</I><B>]}</B>.

+subsequently reset.
+<DT><B>HISTCMD</B>
+
+<DD>
+The history number, or index in the history list, of the current
+command.
+Assignments to
+<FONT SIZE=-1><B>HISTCMD</B>
+
+</FONT>

+describes the type of machine on which
+<B>bash</B>
+
+is executing.
+The default is system-dependent.
+<DT><B>LINENO</B>
+
+<DD>
+Each time this parameter is referenced, the shell substitutes
+a decimal number representing the current sequential line number
+(starting with 1) within a script or function.  When not in a
+script or function, the value substituted is not guaranteed to
+be meaningful.
+If
+<FONT SIZE=-1><B>LINENO</B>
+
+</FONT>
+is unset, it loses its special properties, even if it is
+subsequently reset.
+<DT><B>MACHTYPE</B>

+Automatically set to a string that
+describes the operating system on which
+<B>bash</B>
+
+is executing.
+The default is system-dependent.
+<DT><B>PIPESTATUS</B>
+
+<DD>
+An array variable (see
+<B>Arrays</B>
+

+<DT><B>RANDOM</B>
+
+<DD>
+Each time this parameter is referenced, it expands to a random integer
+between 0 and 32767.
+Assigning
+a value to
+<FONT SIZE=-1><B>RANDOM</B>
+
+</FONT>
+initializes (seeds) the sequence of random numbers.
+If
+<FONT SIZE=-1><B>RANDOM</B>
+
+</FONT>
+is unset, it loses its special properties, even if it is
+subsequently reset.
+<DT><B>READLINE_ARGUMENT</B>
+
+<DD>
+Any numeric argument given to a readline command that was defined using
+<TT>bind -x</TT>
+
+(see
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below)
+when it was invoked.

+
+line buffer, for use with
+<TT>bind -x</TT>
+
+(see
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+

+below).
+<DT><B>REPLY</B>
+
+<DD>
+Set to the line of input read by the
+<B>read</B>
+
+builtin command when no arguments are supplied.
+<DT><B>SECONDS</B>
+
+<DD>
+Each time this parameter is
+referenced, it expands to the number of seconds since shell invocation.
+If a value is assigned to
+<FONT SIZE=-1><B>SECONDS</B>,
+
+</FONT>
+the value returned upon subsequent
+references is
+the number of seconds since the assignment plus the value assigned.
+The number of seconds at shell invocation and the current time are always
+determined by querying the system clock.
+If
+<FONT SIZE=-1><B>SECONDS</B>
+
+</FONT>
+is unset, it loses its special properties, even if it is
+subsequently reset.
+<DT><B>SHELLOPTS</B>
+
+<DD>
+A colon-separated list of enabled shell options.  Each word in
+the list is a valid argument for the
+<B>-o</B>
+
+option to the
+<B>set</B>
+
+builtin command (see
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below).  The options appearing in
+<FONT SIZE=-1><B>SHELLOPTS</B>
+
+</FONT>
+are those reported as
+<I>on</I>
+
+by <B>set -o</B>.
+If this variable is in the environment when
+<B>bash</B>
+
+starts up, each shell option in the list will be enabled before
+reading any startup files.
+This variable is read-only.
+<DT><B>SHLVL</B>
+
+<DD>
+Incremented by one each time an instance of
+<B>bash</B>
+
+is started.
+<DT><B>SRANDOM</B>
+
+<DD>
+This variable expands to a 32-bit pseudo-random number each time it is
+referenced. The random number generator is not linear on systems that
+support <TT>/dev/urandom</TT> or <I>arc4random</I>, so each returned number
+has no relationship to the numbers preceding it.
+The random number generator cannot be seeded, so assignments to this
+variable have no effect.
+If
+<FONT SIZE=-1><B>SRANDOM</B>
+
+</FONT>
+is unset, it loses its special properties,
+even if it is subsequently reset.
+<DT><B>UID</B>
+
+<DD>
+Expands to the user ID of the current user, initialized at shell startup.
+This variable is readonly.
+
+</DL>
+<P>
+
+The following variables are used by the shell.  In some cases,
+<B>bash</B>
+
+assigns a default value to a variable; these cases are noted
+below.
+<P>
+
+
+<DL COMPACT>
+<DT><B>BASH_COMPAT</B>
+
+<DD>
+The value is used to set the shell's compatibility level.
+See
+<FONT SIZE=-1><B>SHELL COMPATIBILITY MODE</B>
+
+</FONT>
+below for a description of the various compatibility
+levels and their effects.
+The value may be a decimal number (e.g., 4.2) or an integer (e.g., 42)
+corresponding to the desired compatibility level.
+If <B>BASH_COMPAT</B> is unset or set to the empty string, the compatibility
+level is set to the default for the current version.
+If <B>BASH_COMPAT</B> is set to a value that is not one of the valid
+compatibility levels, the shell prints an error message and sets the
+compatibility level to the default for the current version.
+The valid values correspond to the compatibility levels
+described below under
+<FONT SIZE=-1><B>SHELL COMPATIBILITY MODE</B>.
+
+</FONT>
+For example, 4.2 and 42 are valid values that correspond
+to the <B>compat42</B> <B>shopt</B> option
+and set the compatibility level to 42.
+The current version is also a valid value.
+<DT><B>BASH_ENV</B>
+
+<DD>
+If this parameter is set when <B>bash</B> is executing a shell script,
+its value is interpreted as a filename containing commands to
+initialize the shell, as in
+<A HREF="file:~/.bashrc"><I>~/.bashrc</I></A>.
+
+The value of
+<FONT SIZE=-1><B>BASH_ENV</B>
+
+</FONT>
+is subjected to parameter expansion, command substitution, and arithmetic
+expansion before being interpreted as a filename.
+<FONT SIZE=-1><B>PATH</B>
+
+</FONT>
+is not used to search for the resultant filename.
+<DT><B>BASH_XTRACEFD</B>
+
+<DD>
+If set to an integer corresponding to a valid file descriptor, <B>bash</B>
+will write the trace output generated when
+<TT>set -x</TT>
+
+is enabled to that file descriptor.
+The file descriptor is closed when
+<FONT SIZE=-1><B>BASH_XTRACEFD</B>
+
+</FONT>
+is unset or assigned a new value.
+Unsetting
+<FONT SIZE=-1><B>BASH_XTRACEFD</B>
+
+</FONT>
+or assigning it the empty string causes the
+trace output to be sent to the standard error.
+Note that setting
+<FONT SIZE=-1><B>BASH_XTRACEFD</B>
+
+</FONT>
+to 2 (the standard error file
+descriptor) and then unsetting it will result in the standard error
+being closed.
+<DT><B>CDPATH</B>
+
+<DD>
+The search path for the
+<B>cd</B>
+
+command.
+This is a colon-separated list of directories in which the shell looks
+for destination directories specified by the
+<B>cd</B>
+
+command.
+A sample value is
+<TT>&quot;.:~:/usr&quot;</TT>.
+
+<DT><B>CHILD_MAX</B>
+
+<DD>
+Set the number of exited child status values for the shell to remember.
+Bash will not allow this value to be decreased below a POSIX-mandated
+minimum, and there is a maximum value (currently 8192) that this may
+not exceed.
+The minimum value is system-dependent.
+<DT><B>COLUMNS</B>
+
+<DD>
+Used by the <B>select</B> compound command to determine the terminal width
+when printing selection lists.
+Automatically set if the
+<B>checkwinsize</B>
+
+option is enabled or in an interactive shell upon receipt of a
+<FONT SIZE=-1><B>SIGWINCH</B>.
+
+</FONT>
+<DT><B>COMPREPLY</B>
+
+<DD>
+An array variable from which <B>bash</B> reads the possible completions
+generated by a shell function invoked by the programmable completion
+facility (see <B>Programmable Completion</B> below).
+Each array element contains one possible completion.
+<DT><B>EMACS</B>
+
+<DD>
+If <B>bash</B> finds this variable in the environment when the shell starts
+with value
+<TT>t</TT>,
+
+it assumes that the shell is running in an Emacs shell buffer and disables
+line editing.
+<DT><B>ENV</B>
+
+<DD>
+Expanded and executed similarly to
+<FONT SIZE=-1><B>BASH_ENV</B>
+
+</FONT>
+(see <B>INVOCATION</B> above)
+when an interactive shell is invoked in <I>posix mode</I>.
+<DT><B>EXECIGNORE</B>
+
+<DD>
+A colon-separated list of shell patterns (see <B>Pattern Matching</B>)
+defining the list of filenames to be ignored by command search using
+<B>PATH</B>.
+Files whose full pathnames match one of these patterns are not considered
+executable files for the purposes of completion and command execution
+via <B>PATH</B> lookup.
+This does not affect the behavior of the <B>[</B>, <B>test</B>, and <B>[[</B>
+commands.
+Full pathnames in the command hash table are not subject to <B>EXECIGNORE</B>.
+Use this variable to ignore shared library files that have the executable
+bit set, but are not executable files.
+The pattern matching honors the setting of the <B>extglob</B> shell
+option.
+<DT><B>FCEDIT</B>
+
+<DD>
+The default editor for the
+<B>fc</B>
+
+builtin command.
+<DT><B>FIGNORE</B>
+
+<DD>
+A colon-separated list of suffixes to ignore when performing
+filename completion (see
+<FONT SIZE=-1><B>READLINE</B>
+
+</FONT>
+below).
+A filename whose suffix matches one of the entries in
+<FONT SIZE=-1><B>FIGNORE</B>
+
+</FONT>
+is excluded from the list of matched filenames.
+A sample value is
+<TT>&quot;.o:~&quot;</TT>.
+
+<DT><B>FUNCNEST</B>
+
+<DD>
+If set to a numeric value greater than 0, defines a maximum function
+nesting level.  Function invocations that exceed this nesting level
+will cause the current command to abort.
+<DT><B>GLOBIGNORE</B>
+
+<DD>
+A colon-separated list of patterns defining the set of file names to
+be ignored by pathname expansion.
+If a file name matched by a pathname expansion pattern also matches one
+of the patterns in
+<FONT SIZE=-1><B>GLOBIGNORE</B>,
+
+</FONT>
+it is removed from the list of matches.
+<DT><B>HISTCONTROL</B>
+
+<DD>
+A colon-separated list of values controlling how commands are saved on
+the history list.
+If the list of values includes
+<I>ignorespace</I>,
+
+lines which begin with a
+<B>space</B>
+
+character are not saved in the history list.
+A value of
+<I>ignoredups</I>
+
+causes lines matching the previous history entry to not be saved.
+A value of
+<I>ignoreboth</I>
+
+is shorthand for <I>ignorespace</I> and <I>ignoredups</I>.
+A value of
+<I>erasedups</I>
+
+causes all previous lines matching the current line to be removed from
+the history list before that line is saved.
+Any value not in the above list is ignored.
+If
+<FONT SIZE=-1><B>HISTCONTROL</B>
+
+</FONT>
+is unset, or does not include a valid value,
+all lines read by the shell parser are saved on the history list,
+subject to the value of
+<FONT SIZE=-1><B>HISTIGNORE</B>.
+
+</FONT>
+The second and subsequent lines of a multi-line compound command are
+not tested, and are added to the history regardless of the value of
+<FONT SIZE=-1><B>HISTCONTROL</B>.
+
+</FONT>
+<DT><B>HISTFILE</B>
+
+<DD>
+The name of the file in which command history is saved (see
+<FONT SIZE=-1><B>HISTORY</B>
+
+</FONT>
+below).  The default value is <A HREF="file:~/.bash_history"><I>~/.bash_history</I></A>.  If unset, the
+command history is not saved when a shell exits.
+<DT><B>HISTFILESIZE</B>
+
+<DD>
+The maximum number of lines contained in the history file.  When this
+variable is assigned a value, the history file is truncated, if
+necessary,
+to contain no more than that number of lines by removing the oldest entries.
+The history file is also truncated to this size after
+writing it when a shell exits.
+If the value is 0, the history file is truncated to zero size.
+Non-numeric values and numeric values less than zero inhibit truncation.
+The shell sets the default value to the value of <B>HISTSIZE</B>
+after reading any startup files.
+<DT><B>HISTIGNORE</B>
+
+<DD>
+A colon-separated list of patterns used to decide which command lines
+should be saved on the history list.  Each pattern is anchored at the
+beginning of the line and must match the complete line (no implicit
+`<B>*</B>' is appended).  Each pattern is tested against the line
+after the checks specified by
+<FONT SIZE=-1><B>HISTCONTROL</B>
+
+</FONT>
+are applied.
+In addition to the normal shell pattern matching characters, `<B>&amp;</B>'
+matches the previous history line.  `<B>&amp;</B>' may be escaped using a
+backslash; the backslash is removed before attempting a match.
+The second and subsequent lines of a multi-line compound command are
+not tested, and are added to the history regardless of the value of
+<FONT SIZE=-1><B>HISTIGNORE</B>.
+
+</FONT>
+The pattern matching honors the setting of the <B>extglob</B> shell
+option.
+<DT><B>HISTSIZE</B>
+
+<DD>
+The number of commands to remember in the command history (see
+<FONT SIZE=-1><B>HISTORY</B>
+
+</FONT>
+below).
+If the value is 0, commands are not saved in the history list.
+Numeric values less than zero result in every command being saved
+on the history list (there is no limit).
+The shell sets the default value to 500 after reading any startup files.
+<DT><B>HISTTIMEFORMAT</B>
+
+<DD>
+If this variable is set and not null, its value is used as a format string
+for <I>strftime</I>(3) to print the time stamp associated with each history
+entry displayed by the <B>history</B> builtin.
+If this variable is set, time stamps are written to the history file so
+they may be preserved across shell sessions.
+This uses the history comment character to distinguish timestamps from
+other history lines.
+<DT><B>HOME</B>
+
+<DD>
+The home directory of the current user; the default argument for the
+<B>cd</B> builtin command.
+The value of this variable is also used when performing tilde expansion.
+<DT><B>HOSTFILE</B>
+
+<DD>
+Contains the name of a file in the same format as
+
+<I>/etc/hosts</I>
+
+that should be read when the shell needs to complete a
+hostname.
+The list of possible hostname completions may be changed while the
+shell is running;
+the next time hostname completion is attempted after the
+value is changed,
+<B>bash</B>
+
+adds the contents of the new file to the existing list.
+If
+<FONT SIZE=-1><B>HOSTFILE</B>
+
+</FONT>
+is set, but has no value, or does not name a readable file,
+<B>bash</B> attempts to read
+
+<I>/etc/hosts</I>
+
+to obtain the list of possible hostname completions.
+When
+<FONT SIZE=-1><B>HOSTFILE</B>
+
+</FONT>
+is unset, the hostname list is cleared.
+<DT><B>IFS</B>
+
+<DD>
+The
+<I>Internal Field Separator</I>
+
+that is used
+for word splitting after expansion and to
+split lines into words with the
+<B>read</B>
+
+builtin command.  The default value is
+``&lt;space&gt;&lt;tab&gt;&lt;newline&gt;''.
+<DT><B>IGNOREEOF</B>
+
+<DD>
+Controls the
+action of an interactive shell on receipt of an
+<FONT SIZE=-1><B>EOF</B>
+
+</FONT>
+character as the sole input.  If set, the value is the number of
+consecutive
+<FONT SIZE=-1><B>EOF</B>
+
+</FONT>
+characters which must be
+typed as the first characters on an input line before
+<B>bash</B>
+
+exits.  If the variable exists but does not have a numeric value, or
+has no value, the default value is 10.  If it does not exist,
+<FONT SIZE=-1><B>EOF</B>
+
+</FONT>
+signifies the end of input to the shell.
+<DT><B>INPUTRC</B>
+
+<DD>
+The filename for the
+<B>readline</B>
+
+startup file, overriding the default of
+
+<A HREF="file:~/.inputrc"><I>~/.inputrc</I></A>
+
+(see
+<FONT SIZE=-1><B>READLINE</B>
+
+</FONT>
+below).
+<DT><B>INSIDE_EMACS</B>
+
+<DD>
+If this variable appears in the environment when the shell starts,
+<B>bash</B> assumes that it is running inside an Emacs shell buffer
+and may disable line editing, depending on the value of <B>TERM</B>.
+<DT><B>LANG</B>
+
+<DD>
+Used to determine the locale category for any category not specifically
+selected with a variable starting with <B>LC_</B>.
+<DT><B>LC_ALL</B>
+
+<DD>
+This variable overrides the value of
+<FONT SIZE=-1><B>LANG</B>
+
+</FONT>
+and any other
+<B>LC_</B> variable specifying a locale category.
+<DT><B>LC_COLLATE</B>
+
+<DD>
+This variable determines the collation order used when sorting the
+results of pathname expansion, and determines the behavior of range
+expressions, equivalence classes, and collating sequences within
+pathname expansion and pattern matching.
+<DT><B>LC_CTYPE</B>
+
+<DD>
+This variable determines the interpretation of characters and the
+behavior of character classes within pathname expansion and pattern
+matching.
+<DT><B>LC_MESSAGES</B>
+
+<DD>
+This variable determines the locale used to translate double-quoted
+strings preceded by a <B>$</B>.
+<DT><B>LC_NUMERIC</B>
+
+<DD>
+This variable determines the locale category used for number formatting.
+<DT><B>LC_TIME</B>
+
+<DD>
+This variable determines the locale category used for data and time
+formatting.
+<DT><B>LINES</B>
+
+<DD>
+Used by the <B>select</B> compound command to determine the column length
+for printing selection lists.
+Automatically set if the
+<B>checkwinsize</B>
+
+option is enabled or in an interactive shell upon receipt of a
+<FONT SIZE=-1><B>SIGWINCH</B>.
+
+</FONT>
+<DT><B>MAIL</B>
+
+<DD>
+If this parameter is set to a file or directory name and the
+<FONT SIZE=-1><B>MAILPATH</B>
+
+</FONT>
+variable is not set,
+<B>bash</B>
+
+informs the user of the arrival of mail in the specified file or
+Maildir-format directory.
+<DT><B>MAILCHECK</B>
+
+<DD>
+Specifies how
+often (in seconds)
+<B>bash</B>
+
+checks for mail.  The default is 60 seconds.  When it is time to check
+for mail, the shell does so before displaying the primary prompt.
+If this variable is unset, or set to a value that is not a number
+greater than or equal to zero, the shell disables mail checking.
+<DT><B>MAILPATH</B>
+
+<DD>
+A colon-separated list of filenames to be checked for mail.
+The message to be printed when mail arrives in a particular file
+may be specified by separating the filename from the message with a `?'.
+When used in the text of the message, <B>$_</B> expands to the name of
+the current mailfile.
+Example:
+<DL COMPACT><DT><DD>
+<P>
+
+<B>MAILPATH</B>=aq/var/mail/bfox?&quot;You have mail&quot;:~/shell-mail?&quot;$_ has mail!&quot;aq
+<P>
+
+<B>Bash</B>
+
+can be configured to supply
+a default value for this variable (there is no value by default),
+but the location of the user
+mail files that it uses is system dependent (e.g., /var/mail/<B>$USER</B>).
+</DL>
+
+<DT><B>OPTERR</B>
+
+<DD>
+If set to the value 1,
+<B>bash</B>
+
+displays error messages generated by the
+<B>getopts</B>
+
+builtin command (see
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below).
+<FONT SIZE=-1><B>OPTERR</B>
+
+</FONT>
+is initialized to 1 each time the shell is invoked or a shell
+script is executed.
+<DT><B>PATH</B>
+
+<DD>
+The search path for commands.  It
+is a colon-separated list of directories in which
+the shell looks for commands (see
+<FONT SIZE=-1><B>COMMAND EXECUTION</B>
+
+</FONT>
+below).
+A zero-length (null) directory name in the value of
+<FONT SIZE=-1><B>PATH</B>
+
+</FONT>
+indicates the current directory.
+A null directory name may appear as two adjacent colons, or as an initial
+or trailing colon.
+The default path is system-dependent,
+and is set by the administrator who installs
+<B>bash</B>.
+
+A common value is
+
+<TT>/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin</TT>.
+
+
+<DT><B>POSIXLY_CORRECT</B>
+
+<DD>
+If this variable is in the environment when <B>bash</B> starts, the shell
+enters <I>posix mode</I> before reading the startup files, as if the
+<B>--posix</B>
+
+invocation option had been supplied.  If it is set while the shell is
+running, <B>bash</B> enables <I>posix mode</I>, as if the command
+<TT>set -o posix</TT>
+
+had been executed.
+When the shell enters <I>posix mode</I>, it sets this variable if it was
+not already set.
+<DT><B>PROMPT_COMMAND</B>
+
+<DD>
+If this variable is set, and is an array,
+the value of each set element is executed as a command
+prior to issuing each primary prompt.
+If this is set but not an array variable, 
+its value is used as a command to execute instead.
+<DT><B>PROMPT_DIRTRIM</B>
+
+<DD>
+If set to a number greater than zero, the value is used as the number of
+trailing directory components to retain when expanding the <B>\w</B> and
+<B>\W</B> prompt string escapes (see
+<FONT SIZE=-1><B>PROMPTING</B>
+
+</FONT>
+below).  Characters removed are replaced with an ellipsis.
+<DT><B>PS0</B>
+
+<DD>
+The value of this parameter is expanded (see
+<FONT SIZE=-1><B>PROMPTING</B>
+
+</FONT>
+below) and displayed by interactive shells after reading a command
+and before the command is executed.
+<DT><B>PS1</B>
+
+<DD>
+The value of this parameter is expanded (see
+<FONT SIZE=-1><B>PROMPTING</B>
+
+</FONT>
+below) and used as the primary prompt string.  The default value is
+``<B>\s-\v\$ </B>''.
+<DT><B>PS2</B>
+
+<DD>
+The value of this parameter is expanded as with
+<FONT SIZE=-1><B>PS1</B>
+
+</FONT>
+and used as the secondary prompt string.  The default is
+``<B>&gt; </B>''.
+<DT><B>PS3</B>
+
+<DD>
+The value of this parameter is used as the prompt for the
+<B>select</B>
+
+command (see
+<FONT SIZE=-1><B>SHELL GRAMMAR</B>
+
+</FONT>
+above).
+<DT><B>PS4</B>
+
+<DD>
+The value of this parameter is expanded as with
+<FONT SIZE=-1><B>PS1</B>
+
+</FONT>
+and the value is printed before each command
+<B>bash</B>
+
+displays during an execution trace.  The first character of
+the expanded value of
+<FONT SIZE=-1><B>PS4</B>
+
+</FONT>
+is replicated multiple times, as necessary, to indicate multiple
+levels of indirection.  The default is ``<B>+ </B>''.
+<DT><B>SHELL</B>
+
+<DD>
+This variable expands to the full pathname to the shell.
+If it is not set when the shell starts,
+<B>bash</B>
+
+assigns to it the full pathname of the current user's login shell.
+<DT><B>TIMEFORMAT</B>
+
+<DD>
+The value of this parameter is used as a format string specifying
+how the timing information for pipelines prefixed with the
+<B>time</B>
+
+reserved word should be displayed.
+The <B>%</B> character introduces an escape sequence that is
+expanded to a time value or other information.
+The escape sequences and their meanings are as follows; the
+braces denote optional portions.
+<P>
+<DL COMPACT><DT><DD>
+
+<DL COMPACT>
+<DT><B>%%</B>
+
+<DD>
+A literal <B>%</B>.
+<DT><B>%[</B><I>p</I>][l]R
+
+<DD>
+The elapsed time in seconds.
+<DT><B>%[</B><I>p</I>][l]U
+
+<DD>
+The number of CPU seconds spent in user mode.
+<DT><B>%[</B><I>p</I>][l]S
+
+<DD>
+The number of CPU seconds spent in system mode.
+<DT><B>%P</B>
+
+<DD>
+The CPU percentage, computed as (%U + %S) / %R.
+
+</DL></DL>
+
+<DT><DD>
+The optional <I>p</I> is a digit specifying the <I>precision</I>,
+the number of fractional digits after a decimal point.
+A value of 0 causes no decimal point or fraction to be output.
+At most three places after the decimal point may be specified;
+values of <I>p</I> greater than 3 are changed to 3.
+If <I>p</I> is not specified, the value 3 is used.
+<DT><DD>
+The optional <B>l</B> specifies a longer format, including
+minutes, of the form <I>MM</I>m<I>SS</I>.<I>FF</I>s.
+The value of <I>p</I> determines whether or not the fraction is
+included.
+<DT><DD>
+If this variable is not set, <B>bash</B> acts as if it had the
+value <B>$aq\nreal\t%3lR\nuser\t%3lU\nsys\t%3lSaq</B>.
+If the value is null, no timing information is displayed.
+A trailing newline is added when the format string is displayed.
+
+<DT><B>TMOUT</B>
+
+<DD>
+If set to a value greater than zero,
+<FONT SIZE=-1><B>TMOUT</B>
+
+</FONT>
+is treated as the
+default timeout for the <B>read</B> builtin.
+The <B>select</B> command terminates if input does not arrive
+after
+<FONT SIZE=-1><B>TMOUT</B>
+
+</FONT>
+seconds when input is coming from a terminal.
+In an interactive shell, the value is interpreted as the
+number of seconds to wait for a line of input after issuing the
+primary prompt.
+<B>Bash</B>
+
+terminates after waiting for that number of seconds if a complete
+line of input does not arrive.
+<DT><B>TMPDIR</B>
+
+<DD>
+If set, <B>bash</B> uses its value as the name of a directory in which
+<B>bash</B> creates temporary files for the shell's use.
+<DT><B>auto_resume</B>
+
+<DD>
+This variable controls how the shell interacts with the user and
+job control.  If this variable is set, single word simple
+commands without redirections are treated as candidates for resumption
+of an existing stopped job.  There is no ambiguity allowed; if there is
+more than one job beginning with the string typed, the job most recently
+accessed is selected.  The
+<I>name</I>
+
+of a stopped job, in this context, is the command line used to
+start it.
+If set to the value
+<I>exact</I>,
+
+the string supplied must match the name of a stopped job exactly;
+if set to
+<I>substring</I>,
+
+the string supplied needs to match a substring of the name of a
+stopped job.  The
+<I>substring</I>
+
+value provides functionality analogous to the
+<B>%?</B>
+
+job identifier (see
+<FONT SIZE=-1><B>JOB CONTROL</B>
+
+</FONT>
+below).  If set to any other value, the supplied string must
+be a prefix of a stopped job's name; this provides functionality
+analogous to the <B>%</B><I>string</I> job identifier.
+<DT><B>histchars</B>
+
+<DD>
+The two or three characters which control history expansion
+and tokenization (see
+<FONT SIZE=-1><B>HISTORY EXPANSION</B>
+
+</FONT>
+below).  The first character is the <I>history expansion</I> character,
+the character which signals the start of a history
+expansion, normally `<B>!</B>'.
+The second character is the <I>quick substitution</I>
+character, which is used as shorthand for re-running the previous
+command entered, substituting one string for another in the command.
+The default is `<B>^</B>'.
+The optional third character is the character
+which indicates that the remainder of the line is a comment when found
+as the first character of a word, normally `<B>#</B>'.  The history
+comment character causes history substitution to be skipped for the
+remaining words on the line.  It does not necessarily cause the shell
+parser to treat the rest of the line as a comment.
+
+</DL>
+<A NAME="lbAX">&nbsp;</A>
+<H4>Arrays</H4>
+
+<B>Bash</B>
+
+provides one-dimensional indexed and associative array variables.
+Any variable may be used as an indexed array; the
+<B>declare</B>
+
+builtin will explicitly declare an array.
+There is no maximum
+limit on the size of an array, nor any requirement that members
+be indexed or assigned contiguously.
+Indexed arrays are referenced using integers (including arithmetic
+expressions) and are zero-based; associative arrays are referenced
+using arbitrary strings.
+Unless otherwise noted, indexed array indices must be non-negative integers.
+<P>
+
+An indexed array is created automatically if any variable is assigned to
+using the syntax <I>name</I>[<I>subscript</I>]=<I>value</I>.  The
+<I>subscript</I>
+
+is treated as an arithmetic expression that must evaluate to a number.
+To explicitly declare an indexed array, use
+<B>declare -a </B><I>name</I>
+
+(see
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below).
+<B>declare -a </B><I>name</I>[<I>subscript</I>]
+
+is also accepted; the <I>subscript</I> is ignored.
+<P>
+
+Associative arrays are created using
+<B>declare -A </B><I>name</I>.
+
+<P>
+
+Attributes may be
+specified for an array variable using the
+<B>declare</B>
+
+and
+<B>readonly</B>
+
+builtins.  Each attribute applies to all members of an array.
+<P>
+
+Arrays are assigned to using compound assignments of the form
+<I>name</I>=<B>(</B>value<I>1</I> ... value<I>n</I><B>)</B>, where each
+<I>value</I> may be of the form [<I>subscript</I>]=<I>string</I>.
+Indexed array assignments do not require anything but <I>string</I>.
+Each <I>value</I> in the list is expanded using all the shell expansions
+described below under
+<FONT SIZE=-1><B>EXPANSION</B>.
+
+</FONT>
+When assigning to indexed arrays, if the optional brackets and subscript
+are supplied, that index is assigned to;
+otherwise the index of the element assigned is the last index assigned
+to by the statement plus one.  Indexing starts at zero.
+<P>
+
+When assigning to an associative array, the words in a compound assignment
+may be either assignment statements, for which the subscript is required,
+or a list of words that is interpreted as a sequence of alternating keys
+and values:
+<I>name</I>=<B>( </B><I>key1 value1 key2 value2</I> ...<B>)</B>.
+These are treated identically to
+<I>name</I>=<B>(</B> [<I>key1</I>]=<I>value1</I> [<I>key2</I>]=<I>value2</I> ...<B>)</B>.
+The first word in the list determines how the remaining words
+are interpreted; all assignments in a list must be of the same type.
+When using key/value pairs, the keys may not be missing or empty;
+a final missing value is treated like the empty string.
+<P>
+
+This syntax is also accepted by the
+<B>declare</B>
+
+builtin.  Individual array elements may be assigned to using the
+<I>name</I>[<I>subscript</I>]=<I>value</I> syntax introduced above.
+When assigning to an indexed array, if
+<I>name</I>
+
+is subscripted by a negative number, that number is
+interpreted as relative to one greater than the maximum index of
+<I>name</I>, so negative indices count back from the end of the
+array, and an index of -1 references the last element.
+<P>
+
+The += operator will append to an array variable when assigning
+using the compound assignment syntax; see
+<FONT SIZE=-1><B>PARAMETERS</B>
+
+</FONT>
+above.
+<P>
+
+Any element of an array may be referenced using
+${<I>name</I>[<I>subscript</I>]}.  The braces are required to avoid
+conflicts with pathname expansion.  If
+<I>subscript</I> is <B>@</B> or <B>*</B>, the word expands to
+all members of <I>name</I>.  These subscripts differ only when the
+word appears within double quotes.  If the word is double-quoted,
+${<I>name</I>[*]} expands to a single
+word with the value of each array member separated by the first
+character of the
+<FONT SIZE=-1><B>IFS</B>
+
+</FONT>
+special variable, and ${<I>name</I>[@]} expands each element of
+<I>name</I> to a separate word.  When there are no array members,
+${<I>name</I>[@]} expands to nothing.
+If the double-quoted expansion occurs within a word, the expansion of
+the first parameter is joined with the beginning part of the original
+word, and the expansion of the last parameter is joined with the last
+part of the original word.
+This is analogous to the expansion
+of the special parameters <B>*</B> and <B>@</B> (see
+<B>Special Parameters</B>
+
+above).  ${#<I>name</I>[<I>subscript</I>]} expands to the length of
+${<I>name</I>[<I>subscript</I>]}.  If <I>subscript</I> is <B>*</B> or
+<B>@</B>, the expansion is the number of elements in the array.
+If the
+<I>subscript</I>
+
+used to reference an element of an indexed array
+evaluates to a number less than zero, it is
+interpreted as relative to one greater than the maximum index of the array,
+so negative indices count back from the end of the
+array, and an index of -1 references the last element.
+<P>
+
+Referencing an array variable without a subscript is equivalent to
+referencing the array with a subscript of 0.
+Any reference to a variable using a valid subscript is legal, and
+<B>bash</B>
+
+will create an array if necessary.
+<P>
+
+An array variable is considered set if a subscript has been assigned a
+value.  The null string is a valid value.
+<P>
+
+It is possible to obtain the keys (indices) of an array as well as the values.
+${<B>!</B><I>name</I>[<I>@</I>]} and ${<B>!</B><I>name</I>[<I>*</I>]}
+expand to the indices assigned in array variable <I>name</I>.
+The treatment when in double quotes is similar to the expansion of the
+special parameters <I>@</I> and <I>*</I> within double quotes.
+<P>
+
+The
+<B>unset</B>
+
+builtin is used to destroy arrays.  <B>unset</B> <I>name</I>[<I>subscript</I>]
+destroys the array element at index <I>subscript</I>,
+for both indexed and associative arrays.
+Negative subscripts to indexed arrays are interpreted as described above.
+Unsetting the last element of an array variable does not unset the variable.
+<B>unset</B> <I>name</I>, where <I>name</I> is an array,
+removes the entire array.
+<B>unset</B> <I>name</I>[<I>subscript</I>], where
+<I>subscript</I> is <B>*</B> or <B>@</B>, behaves differently depending on
+whether <I>name</I> is an indexed or associative array.
+If <I>name</I> is an associative array, this unsets the element with
+subscript <B>*</B> or <B>@</B>.
+If <I>name</I> is an indexed array, unset removes all of the elements but
+does not remove the array itself.
+<P>
+
+When using a variable name with a subscript as an argument to a command,
+such as with <B>unset</B>, without using the word expansion syntax
+described above, the argument is subject to pathname expansion.
+If pathname expansion is not desired, the argument should be quoted.
+<P>
+
+The
+<B>declare</B>,
+
+<B>local</B>,
+
+and
+<B>readonly</B>
+
+builtins each accept a
+<B>-a</B>
+
+option to specify an indexed array and a
+<B>-A</B>
+
+option to specify an associative array.
+If both options are supplied,
+<B>-A</B>
+
+takes precedence.
+The

+
+option to assign a list of words read from the standard input
+to an array.  The

+<H3>EXPANSION</H3>
+
+Expansion is performed on the command line after it has been split into
+words.  There are seven kinds of expansion performed:
+<I>brace expansion</I>,
+
+<I>tilde expansion</I>,
+
+<I>parameter and variable expansion</I>,
+
+<I>command substitution</I>,
+
+<I>arithmetic expansion</I>,

+
+<P>
+
+The order of expansions is:
+brace expansion;
+tilde expansion, parameter and variable expansion, arithmetic expansion,
+and command substitution (done in a left-to-right fashion);
+word splitting;
+and pathname expansion.
+<P>
+
+On systems that can support it, there is an additional expansion

+<H4>Brace Expansion</H4>
+
+<I>Brace expansion</I>
+
+is a mechanism by which arbitrary strings
+may be generated.  This mechanism is similar to
+<I>pathname expansion</I>, but the filenames generated
+need not exist.  Patterns to be brace expanded take
+the form of an optional
+<I>preamble</I>,
+
+followed by either a series of comma-separated strings or
+a sequence expression between a pair of braces, followed by
+an optional
+<I>postscript</I>.
+
+The preamble is prefixed to each string contained
+within the braces, and the postscript is then appended
+to each resulting string, expanding left to right.
+<P>
+
+Brace expansions may be nested.  The results of each expanded
+string are not sorted; left to right order is preserved.
+For example, a<B>{</B>d,c,b<B>}</B>e expands into `ade ace abe'.
+<P>
+
+A sequence expression takes the form
+<B>{</B><I>x</I><B>..</B><I>y</I><B>[..</B><I>incr</I><B>]}</B>,
+where <I>x</I> and <I>y</I> are either integers or single letters,
+and <I>incr</I>, an optional increment, is an integer.
+When integers are supplied, the expression expands to each number between
+<I>x</I> and <I>y</I>, inclusive.
+Supplied integers may be prefixed with <I>0</I> to force each term to have the
+same width.
+When either <I>x</I> or y begins with a zero, the shell
+attempts to force all generated terms to contain the same number of digits,
+zero-padding where necessary.
+When letters are supplied, the expression expands to each character
+lexicographically between <I>x</I> and <I>y</I>, inclusive,
+using the default C locale.
+Note that both <I>x</I> and <I>y</I> must be of the same type
+(integer or letter).
+When the increment is supplied, it is used as the difference between
+each term.  The default increment is 1 or -1 as appropriate.
+<P>
+
+Brace expansion is performed before any other expansions,
+and any characters special to other expansions are preserved
+in the result.  It is strictly textual.
+<B>Bash</B>
+
+does not apply any syntactic interpretation to the context of the
+expansion or the text between the braces.
+<P>
+
+A correctly-formed brace expansion must contain unquoted opening
+and closing braces, and at least one unquoted comma or a valid
+sequence expression.
+Any incorrectly formed brace expansion is left unchanged.
+A <B>{</B> or <B>,</B> may be quoted with a backslash to prevent its
+being considered part of a brace expression.
+To avoid conflicts with parameter expansion, the string <B>${</B>
+is not considered eligible for brace expansion, and inhibits brace
+expansion until the closing <B>}</B>.
+<P>
+
+This construct is typically used as shorthand when the common
+prefix of the strings to be generated is longer than in the
+above example:
+<DL COMPACT><DT><DD>
+<P>
+
+mkdir /usr/local/src/bash/{old,new,dist,bugs}
+</DL>
+
+or
+<DL COMPACT><DT><DD>
+chown root /usr/{ucb/{ex,edit},lib/{ex?.?*,how_ex}}
+</DL>
+
+<P>
+
+Brace expansion introduces a slight incompatibility with
+historical versions of
+<B>sh</B>.
+
+<B>sh</B>
+
+does not treat opening or closing braces specially when they
+appear as part of a word, and preserves them in the output.
+<B>Bash</B>
+
+removes braces from words as a consequence of brace
+expansion.  For example, a word entered to
+<B>sh</B>
+
+as <I>file{1,2}</I>
+appears identically in the output.  The same word is
+output as
+<I>file1 file2</I>
+
+after expansion by
+<B>bash</B>.
+
+If strict compatibility with
+<B>sh</B>
+
+is desired, start
+<B>bash</B>
+
+with the
+<B>+B</B>
+
+option or disable brace expansion with the
+<B>+B</B>
+
+option to the
+<B>set</B>
+
+command (see
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below).
+<A NAME="lbBA">&nbsp;</A>
+<H4>Tilde Expansion</H4>
+
+If a word begins with an unquoted tilde character (`<B>~</B>'), all of
+the characters preceding the first unquoted slash (or all characters,
+if there is no unquoted slash) are considered a <I>tilde-prefix</I>.
+If none of the characters in the tilde-prefix are quoted, the
+characters in the tilde-prefix following the tilde are treated as a
+possible <I>login name</I>.
+If this login name is the null string, the tilde is replaced with the
+value of the shell parameter
+<FONT SIZE=-1><B>HOME</B>.
+
+</FONT>
+If
+<FONT SIZE=-1><B>HOME</B>
+
+</FONT>
+is unset, the home directory of the user executing the shell is
+substituted instead.
+Otherwise, the tilde-prefix is replaced with the home directory
+associated with the specified login name.
+<P>
+
+If the tilde-prefix is a `~+', the value of the shell variable
+<FONT SIZE=-1><B>PWD</B>
+
+</FONT>
+replaces the tilde-prefix.
+If the tilde-prefix is a `~-', the value of the shell variable
+<FONT SIZE=-1><B>OLDPWD</B>,
+
+</FONT>
+if it is set, is substituted.
+If the characters following the tilde in the tilde-prefix consist
+of a number <I>N</I>, optionally prefixed
+by a `+' or a `-', the tilde-prefix is replaced with the corresponding
+element from the directory stack, as it would be displayed by the
+<B>dirs</B>
+
+builtin invoked with the tilde-prefix as an argument.
+If the characters following the tilde in the tilde-prefix consist of a
+number without a leading `+' or `-', `+' is assumed.
+<P>
+
+If the login name is invalid, or the tilde expansion fails, the word
+is unchanged.
+<P>
+
+Each variable assignment is checked for unquoted tilde-prefixes immediately
+following a
+<B>:</B>
+
+or the first
+<B>=</B>.
+
+In these cases, tilde expansion is also performed.
+Consequently, one may use filenames with tildes in assignments to
+<FONT SIZE=-1><B>PATH</B>,
+
+</FONT>
+<FONT SIZE=-1><B>MAILPATH</B>,
+
+</FONT>
+and
+<FONT SIZE=-1><B>CDPATH</B>,
+
+</FONT>
+and the shell assigns the expanded value.
+<P>
+
+Bash also performs tilde expansion on words satisfying the conditions of
+variable assignments (as described above under
+<FONT SIZE=-1><B>PARAMETERS</B>)
+
+</FONT>
+when they appear as arguments to simple commands.
+Bash does not do this, except for the <I>declaration</I> commands listed

+<H4>Parameter Expansion</H4>
+
+The `<B>$</B>' character introduces parameter expansion,
+command substitution, or arithmetic expansion.  The parameter name
+or symbol to be expanded may be enclosed in braces, which
+are optional but serve to protect the variable to be expanded from
+characters immediately following it which could be
+interpreted as part of the name.
+<P>
+
+When braces are used, the matching ending brace is the first `<B>}</B>'
+not escaped by a backslash or within a quoted string, and not within an
+embedded arithmetic expansion, command substitution, or parameter
+expansion.
+<P>
+
+
+<DL COMPACT>
+<DT>${<I>parameter</I>}<DD>
+The value of <I>parameter</I> is substituted.  The braces are required
+when
+<I>parameter</I>
+
+is a positional parameter with more than one digit,
+or when
+<I>parameter</I>
+
+is followed by a character which is not to be
+interpreted as part of its name.
+The <I>parameter</I> is a shell parameter as described above
+<B>PARAMETERS</B>) or an array reference (<B>Arrays</B>).
+
+</DL>
+<P>
+
+If the first character of <I>parameter</I> is an exclamation point (<B>!</B>),
+and <I>parameter</I> is not a <I>nameref</I>,
+it introduces a level of indirection.
+<B>Bash</B> uses the value formed by expanding the rest of
+<I>parameter</I> as the new <I>parameter</I>; this is then
+expanded and that value is used in the rest of the expansion, rather
+than the expansion of the original <I>parameter</I>.
+This is known as <I>indirect expansion</I>.
+The value is subject to tilde expansion,
+parameter expansion, command substitution, and arithmetic expansion.
+If <I>parameter</I> is a nameref, this expands to the name of the
+parameter referenced by <I>parameter</I> instead of performing the
+complete indirect expansion.
+The exceptions to this are the expansions of ${<B>!</B><I>prefix</I><B>*</B>} and
+${<B>!</B><I>name</I>[<I>@</I>]} described below.
+The exclamation point must immediately follow the left brace in order to
+introduce indirection.
+<P>
+
+In each of the cases below, <I>word</I> is subject to tilde expansion,
+parameter expansion, command substitution, and arithmetic expansion.
+<P>
+
+When not performing substring expansion, using the forms documented below
+(e.g., <B>:-</B>),

+and extending to the end of the value.
+<I>length</I> and <I>offset</I> are arithmetic expressions (see

+If <I>length</I> evaluates to a number less than zero,
+it is interpreted as an offset in characters
+from the end of the value of <I>parameter</I> rather than
+a number of characters, and the expansion is the characters between
+<I>offset</I> and that result.
+Note that a negative offset must be separated from the colon by at least
+one space to avoid being confused with the <B>:-</B> expansion.
+<P>
+If <I>parameter</I> is <B>@</B> or <B>*</B>, the result is <I>length</I>
+positional parameters beginning at <I>offset</I>.
+A negative <I>offset</I> is taken relative to one greater than the greatest
+positional parameter, so an offset of -1 evaluates to the last positional
+parameter.
+It is an expansion error if <I>length</I> evaluates to a number less than
+zero.

+If <I>parameter</I> is an indexed array name subscripted by @ or *,

+Substring expansion applied to an associative array produces undefined

+Users should take care if <I>string</I> is double-quoted to avoid

+Pattern substitution performs the check for unquoted <B>&amp;</B> after

+<H4>Command Substitution</H4>
+
+<I>Command substitution</I> allows the output of a command to replace
+the command name.  There are two forms:
+<DL COMPACT><DT><DD>
+<P>
+
+<B>$(</B><I>command</I><B>)</B>
+</DL>
+
+or
+<DL COMPACT><DT><DD>
+<B>`</B><I>command</I><B>`</B>
+</DL>
+
+<P>
+
+<B>Bash</B>
+
+performs the expansion by executing <I>command</I> in a subshell environment
+and replacing the command substitution with the standard output of the
+command, with any trailing newlines deleted.
+Embedded newlines are not deleted, but they may be removed during
+word splitting.
+The command substitution <B>$(cat </B><I>file</I>) can be replaced by
+the equivalent but faster <B>$(&lt; </B><I>file</I>).
+<P>
+
+When the old-style backquote form of substitution is used,
+backslash retains its literal meaning except when followed by
+<B>$</B>,
+
+<B>`</B>,
+
+or
+<B>\</B>.
+
+The first backquote not preceded by a backslash terminates the
+command substitution.
+When using the $(<I>command</I>) form, all characters between the
+parentheses make up the command; none are treated specially.
+<P>
+
+Command substitutions may be nested.  To nest when using the backquoted form,
+escape the inner backquotes with backslashes.
+<P>
+
+If the substitution appears within double quotes, word splitting and
+pathname expansion are not performed on the results.
+<A NAME="lbBD">&nbsp;</A>
+<H4>Arithmetic Expansion</H4>
+
+Arithmetic expansion allows the evaluation of an arithmetic expression
+and the substitution of the result.  The format for arithmetic expansion is:
+<DL COMPACT><DT><DD>
+<P>
+
+<B>$((</B><I>expression</I><B>))</B>
+</DL>
+
+<P>
+
+The
+<I>expression</I>
+
+undergoes the same expansions
+as if it were within double quotes,
+but double quote characters in <I>expression</I> are not treated specially
+and are removed.
+All tokens in the expression undergo parameter and variable expansion,
+command substitution, and quote removal.
+The result is treated as the arithmetic expression to be evaluated.
+Arithmetic expansions may be nested.
+<P>
+
+The evaluation is performed according to the rules listed below under
+<FONT SIZE=-1><B>ARITHMETIC EVALUATION</B>.
+
+</FONT>
+If
+<I>expression</I>
+
+is invalid,
+<B>bash</B>
+
+prints a message indicating failure and no substitution occurs.
+<A NAME="lbBE">&nbsp;</A>
+<H4>Process Substitution</H4>
+
+<I>Process substitution</I> allows a process's input or output to be
+referred to using a filename.
+It takes the form of
+<B>&lt;(</B><I>list</I><B>)</B>
+or
+<B>&gt;(</B><I>list</I><B>)</B>.
+The process <I>list</I> is run asynchronously, and its input or output
+appears as a filename.
+This filename is
+passed as an argument to the current command as the result of the
+expansion.
+If the <B>&gt;(</B><I>list</I><B>)</B> form is used, writing to
+the file will provide input for <I>list</I>.  If the
+<B>&lt;(</B><I>list</I><B>)</B> form is used, the file passed as an
+argument should be read to obtain the output of <I>list</I>.
+Process substitution is supported on systems that support named
+pipes (<I>FIFOs</I>) or the <B>/dev/fd</B> method of naming open files.
+<P>
+
+When available, process substitution is performed
+simultaneously with parameter and variable expansion,
+command substitution,
+and arithmetic expansion.

+<H4>Word Splitting</H4>
+
+The shell scans the results of
+parameter expansion,
+command substitution,
+and
+arithmetic expansion
+that did not occur within double quotes for
+<I>word splitting</I>.
+
+<P>
+
+The shell treats each character of
+<FONT SIZE=-1><B>IFS</B>

+as a delimiter, and splits the results of the other
+expansions into words using these characters as field terminators.
+If
+<FONT SIZE=-1><B>IFS</B>
+
+</FONT>
+is unset, or its
+value is exactly
+<B>&lt;space&gt;&lt;tab&gt;&lt;newline&gt;</B>,

+sequences of
+<B>&lt;space&gt;</B>,
+
+<B>&lt;tab&gt;</B>,

+<B>&lt;newline&gt;</B>
+
+at the beginning and end of the results of the previous
+expansions are ignored, and
+any sequence of
+<FONT SIZE=-1><B>IFS</B>
+

+characters not at the beginning or end serves to delimit words.
+If
+<FONT SIZE=-1><B>IFS</B>

+<B>space</B>,
+

+whitespace characters, delimits a field.
+A sequence of

+whitespace characters is also treated as a delimiter.
+If the value of
+<FONT SIZE=-1><B>IFS</B>
+
+</FONT>
+is null, no word splitting occurs.
+<P>
+
+Explicit null arguments (<B>&quot;&quot;</B> or <B>aqaq</B>) are retained
+and passed to commands as empty strings.
+Unquoted implicit null arguments, resulting from the expansion of
+parameters that have no values, are removed.
+If a parameter with no value is expanded within double quotes, a
+null argument results and is retained
+and passed to a command as an empty string.
+When a quoted null argument appears as part of a word whose expansion is
+non-null, the null argument is removed.
+That is, the word
+<TT>-daqaq</TT> becomes <TT>-d</TT> after word splitting and
+null argument removal.
+<P>
+
+Note that if no expansion occurs, no splitting
+is performed.

+<H4>Pathname Expansion</H4>
+
+After word splitting,

+<B>bash</B>
+
+scans each word for the characters
+<B>*</B>,
+

+<B>[</B>.
+
+If one of these characters appears, and is not quoted, then the word is
+regarded as a

+
+and replaced with an alphabetically sorted list of
+filenames matching the pattern
+(see

+below).
+If no matching filenames are found,
+and the shell option

+
+shell option is set, and no matches are found, an error message
+is printed and the command is not executed.
+If the shell option
+<B>nocaseglob</B>

+of alphabetic characters.
+When a pattern is used for pathname expansion,

+
+at the start of a name or immediately following a slash
+must be matched explicitly, unless the shell option

+
+When not matching pathnames, the

+When matching a pathname, the slash character must always be

+Matches any single character.
+<DT><B>[...]</B>

+any character that falls between those two characters, inclusive,
+using the current locale's collating sequence and character set,
+is matched.  If the first character following the
+<B>[</B>
+
+is a
+<B>!</B>
+
+or a
+<B>^</B>
+
+then any character not enclosed is matched.

+
+If the <B>extglob</B> shell option is enabled using the <B>shopt</B>
+builtin, the shell recognizes several extended pattern matching operators.
+In the following description, a <I>pattern-list</I> is a list of one
+or more patterns separated by a <B>|</B>.
+Composite patterns may be formed using one or more of the following
+sub-patterns:
+<P>
+
+<DL COMPACT><DT><DD>
+<DL COMPACT>
+<DT><B>?(</B><I>pattern-list</I><B>)</B><DD>

+<DT><B>@(</B><I>pattern-list</I><B>)</B><DD>
+Matches one of the given patterns
+<DT><B>!(</B><I>pattern-list</I><B>)</B><DD>
+Matches anything except one of the given patterns
+</DL></DL>
+
+
+<P>
+
+The<B>extglob</B> option changes the behavior of the parser, since the
+parentheses are normally treated as operators with syntactic meaning.
+To ensure that extended matching patterns are parsed correctly, make sure
+that <B>extglob</B> is enabled before parsing constructs containing the
+patterns, including shell functions and command substitutions.
+<P>
+
+When matching filenames, the <B>dotglob</B> shell option determines
+the set of filenames that are tested:
+when <B>dotglob</B> is enabled, the set of filenames includes all files
+beginning with ``.'', but ``.'' and ``..'' must be matched by a
+pattern or sub-pattern that begins with a dot;
+when it is disabled, the set does not
+include any filenames beginning with ``.'' unless the pattern
+or sub-pattern begins with a ``.''.
+As above, ``.'' only has a special meaning when matching filenames.
+<P>
+
+Complicated extended pattern matching against long strings is slow,
+especially when the patterns contain alternations and the strings
+contain multiple matches.
+Using separate matches against shorter strings, or using arrays of
+strings instead of a single long string, may be faster.

+<H4>Quote Removal</H4>
+
+After the preceding expansions, all unquoted occurrences of the
+characters
+<B>\</B>,

+expansions are removed.
+<A NAME="lbBI">&nbsp;</A>
+<H3>REDIRECTION</H3>
+
+Before a command is executed, its input and output
+may be
+<I>redirected</I>
+
+using a special notation interpreted by the shell.
+<I>Redirection</I> allows commands' file handles to be
+duplicated, opened, closed,
+made to refer to different files,
+and can change the files the command reads from and writes to.
+Redirection may also be used to modify file handles in the
+current shell execution environment.
+The following redirection
+operators may precede or appear anywhere within a
+<I>simple command</I>
+
+or may follow a
+<I>command</I>.
+
+Redirections are processed in the order they appear, from
+left to right.
+<P>
+
+Each redirection that may be preceded by a file descriptor number
+may instead be preceded by a word of the form {<I>varname</I>}.
+In this case, for each redirection operator except
+&gt;&amp;- and &lt;&amp;-, the shell will allocate a file descriptor greater
+than or equal to 10 and assign it to <I>varname</I>.
+If &gt;&amp;- or &lt;&amp;- is preceded
+by {<I>varname</I>}, the value of <I>varname</I> defines the file
+descriptor to close.
+If {<I>varname</I>} is supplied, the redirection persists beyond
+the scope of the command, allowing the shell programmer to manage
+the file descriptor's lifetime manually.
+The <B>varredir_close</B> shell option manages this behavior.
+<P>
+
+In the following descriptions, if the file descriptor number is
+omitted, and the first character of the redirection operator is
+<B>&lt;</B>,
+
+the redirection refers to the standard input (file descriptor
+0).  If the first character of the redirection operator is
+<B>&gt;</B>,
+
+the redirection refers to the standard output (file descriptor
+1).
+<P>
+
+The word following the redirection operator in the following
+descriptions, unless otherwise noted, is subjected to
+brace expansion, tilde expansion, parameter and variable expansion,
+command substitution, arithmetic expansion, quote removal,
+pathname expansion, and word splitting.
+If it expands to more than one word,
+<B>bash</B>
+
+reports an error.
+<P>
+
+Note that the order of redirections is significant.  For example,
+the command
+<DL COMPACT><DT><DD>
+<P>
+
+ls <B>&gt;</B> dirlist 2<B>&gt;&amp;</B>1
+</DL>
+
+<P>
+
+directs both standard output and standard error to the file
+<I>dirlist</I>,
+
+while the command
+<DL COMPACT><DT><DD>
+<P>
+
+ls 2<B>&gt;&amp;</B>1 <B>&gt;</B> dirlist
+</DL>
+
+<P>
+
+directs only the standard output to file
+<I>dirlist</I>,
+
+because the standard error was duplicated from the standard output
+before the standard output was redirected to
+<I>dirlist</I>.
+
+<P>
+
+<B>Bash</B> handles several filenames specially when they are used in
+redirections, as described in the following table.
+If the operating system on which <B>bash</B> is running provides these
+special files, bash will use them; otherwise it will emulate them
+internally with the behavior described below.

+<H4>Here Documents</H4>
+
+This type of redirection instructs the shell to read input from the

+<A NAME="lbBT">&nbsp;</A>
+<H3>ALIASES</H3>
+
+<I>Aliases</I> allow a string to be substituted for a word when it is used
+as the first word of a simple command.
+The shell maintains a list of aliases that may be set and unset with the
+<B>alias</B>
+
+and
+<B>unalias</B>
+
+builtin commands (see
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below).
+The first word of each simple command, if unquoted,
+is checked to see if it has an
+alias.  If so, that word is replaced by the text of the alias.
+The characters <B>/</B>, <B>$</B>, <B>`</B>, and <B>=</B> and
+any of the shell <I>metacharacters</I> or quoting characters
+listed above may not appear in an alias name.
+The replacement text may contain any valid shell input,
+including shell metacharacters.
+The first word of the replacement text is tested
+for aliases, but a word that is identical to an alias being expanded
+is not expanded a second time.
+This means that one may alias
+<B>ls</B>
+
+to
+<B>ls -F</B>,
+
+for instance, and
+<B>bash</B>
+
+does not try to recursively expand the replacement text.
+If the last character of the alias value is a
+<I>blank</I>,
+
+then the next command
+word following the alias is also checked for alias expansion.
+<P>
+
+Aliases are created and listed with the
+<B>alias</B>
+
+command, and removed with the
+<B>unalias</B>
+
+command.
+<P>
+
+There is no mechanism for using arguments in the replacement text.
+If arguments are needed, use a shell function (see
+<FONT SIZE=-1><B>FUNCTIONS</B>
+
+</FONT>
+below).
+<P>
+
+Aliases are not expanded when the shell is not interactive, unless
+the
+<B>expand_aliases</B>
+
+shell option is set using
+<B>shopt</B>
+
+(see the description of
+<B>shopt</B>
+
+under
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B></FONT>
+below).
+<P>
+
+The rules concerning the definition and use of aliases are
+somewhat confusing.
+<B>Bash</B>
+
+always reads at least one complete line of input,
+and all lines that make up a compound command,
+before executing any of the commands on that line or the compound command.
+Aliases are expanded when a
+command is read, not when it is executed.  Therefore, an
+alias definition appearing on the same line as another
+command does not take effect until the next line of input is read.
+The commands following the alias definition
+on that line are not affected by the new alias.
+This behavior is also an issue when functions are executed.
+Aliases are expanded when a function definition is read,
+not when the function is executed, because a function definition
+is itself a command.  As a consequence, aliases
+defined in a function are not available until after that
+function is executed.  To be safe, always put
+alias definitions on a separate line, and do not use
+<B>alias</B>
+
+in compound commands.
+<P>
+
+For almost every purpose, aliases are superseded by
+shell functions.
+<A NAME="lbBU">&nbsp;</A>
+<H3>FUNCTIONS</H3>
+
+A shell function, defined as described above under
+<FONT SIZE=-1><B>SHELL GRAMMAR</B>,
+
+</FONT>
+stores a series of commands for later execution.
+When the name of a shell function is used as a simple command name,
+the list of commands associated with that function name is executed.
+Functions are executed in the context of the
+current shell; no new process is created to interpret
+them (contrast this with the execution of a shell script).
+When a function is executed, the arguments to the
+function become the positional parameters
+during its execution.
+The special parameter
+<B>#</B>
+
+is updated to reflect the change.  Special parameter <B>0</B>
+is unchanged.
+The first element of the
+<FONT SIZE=-1><B>FUNCNAME</B>
+
+</FONT>
+variable is set to the name of the function while the function
+is executing.
+<P>
+
+All other aspects of the shell execution
+environment are identical between a function and its caller
+with these exceptions: the
+<FONT SIZE=-1><B>DEBUG</B>
+
+</FONT>
+and
+<B>RETURN</B>
+
+traps (see the description of the
+<B>trap</B>
+
+builtin under
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below) are not inherited unless the function has been given the
+<B>trace</B> attribute (see the description of the
+<FONT SIZE=-1><B>declare</B>
+
+</FONT>
+builtin below) or the
+<B>-o functrace</B> shell option has been enabled with
+the <B>set</B> builtin
+(in which case all functions inherit the <B>DEBUG</B> and <B>RETURN</B> traps),
+and the
+<FONT SIZE=-1><B>ERR</B>
+
+</FONT>
+trap is not inherited unless the <B>-o errtrace</B> shell option has
+been enabled.
+<P>
+
+Variables local to the function may be declared with the
+<B>local</B>
+
+builtin command (<I>local variables</I>).
+Ordinarily, variables and their values
+are shared between the function and its caller.
+If a variable is declared <B>local</B>, the variable's visible scope
+is restricted to that function and its children (including the functions
+it calls).
+<P>
+
+In the following description, the <I>current scope</I> is a currently-
+executing function.
+Previous scopes consist of that function's caller and so on,
+back to the &quot;global&quot; scope, where the shell is not executing
+any shell function.
+Consequently, a local variable at the current scope is a variable
+declared using the <B>local</B> or <B>declare</B> builtins in the
+function that is currently executing.
+<P>
+
+Local variables &quot;shadow&quot; variables with the same name declared at
+previous scopes.
+For instance, a local variable declared in a function
+hides a global variable of the same name: references and assignments
+refer to the local variable, leaving the global variable unmodified.
+When the function returns, the global variable is once again visible.
+<P>
+
+The shell uses <I>dynamic scoping</I> to control a variable's visibility
+within functions.
+With dynamic scoping, visible variables and their values
+are a result of the sequence of function calls that caused execution
+to reach the current function.
+The value of a variable that a function sees depends
+on its value within its caller, if any, whether that caller is
+the &quot;global&quot; scope or another shell function.
+This is also the value that a local variable
+declaration &quot;shadows&quot;, and the value that is restored when the function
+returns.
+<P>
+
+For example, if a variable <I>var</I> is declared as local in function
+<I>func1</I>, and <I>func1</I> calls another function <I>func2</I>,
+references to <I>var</I> made from within <I>func2</I> will resolve to the
+local variable <I>var</I> from <I>func1</I>, shadowing any global variable
+named <I>var</I>.
+<P>
+
+The <B>unset</B> builtin also acts using the same dynamic scope: if a
+variable is local to the current scope, <B>unset</B> will unset it;
+otherwise the unset will refer to the variable found in any calling scope
+as described above.
+If a variable at the current local scope is unset, it will remain so
+(appearing as unset)
+until it is reset in that scope or until the function returns.
+Once the function returns, any instance of the variable at a previous
+scope will become visible.
+If the unset acts on a variable at a previous scope, any instance of a
+variable with that name that had been shadowed will become visible
+(see below how the <B>localvar_unset</B> shell option changes this behavior).
+<P>
+
+The <B>FUNCNEST</B> variable, if set to a numeric value greater
+than 0, defines a maximum function nesting level.  Function
+invocations that exceed the limit cause the entire command to
+abort.
+<P>
+
+If the builtin command
+<B>return</B>
+
+is executed in a function, the function completes and
+execution resumes with the next command after the function
+call.
+Any command associated with the <B>RETURN</B> trap is executed
+before execution resumes.
+When a function completes, the values of the
+positional parameters and the special parameter
+<B>#</B>
+
+are restored to the values they had prior to the function's
+execution.
+<P>
+
+Function names and definitions may be listed with the
+<B>-f</B>
+
+option to the
+<B>declare</B>
+
+or
+<B>typeset</B>
+
+builtin commands.  The
+<B>-F</B>
+
+option to
+<B>declare</B>
+
+or
+<B>typeset</B>
+
+will list the function names only
+(and optionally the source file and line number, if the <B>extdebug</B>
+shell option is enabled).
+Functions may be exported so that child shell processes
+(those created when executing a separate shell invocation)
+automatically have them defined with the
+<B>-f</B>
+
+option to the
+<B>export</B>
+
+builtin.
+A function definition may be deleted using the <B>-f</B> option to
+the
+<B>unset</B>
+
+builtin.
+<P>
+
+Functions may be recursive.
+The <B>FUNCNEST</B> variable may be used to limit the depth of the
+function call stack and restrict the number of function invocations.
+By default, no limit is imposed on the number of recursive calls.
+<A NAME="lbBV">&nbsp;</A>
+<H3>ARITHMETIC EVALUATION</H3>
+
+The shell allows arithmetic expressions to be evaluated, under
+certain circumstances (see the <B>let</B> and <B>declare</B> builtin
+commands, the <B>((</B> compound command, and <B>Arithmetic Expansion</B>).
+Evaluation is done in fixed-width integers with no check for overflow,
+though division by 0 is trapped and flagged as an error.
+The operators and their precedence, associativity, and values
+are the same as in the C language.
+The following list of operators is grouped into levels of
+equal-precedence operators.

+Shell variables are allowed as operands; parameter expansion is
+performed before the expression is evaluated.
+Within an expression, shell variables may also be referenced by name
+without using the parameter expansion syntax.
+A shell variable that is null or unset evaluates to 0 when referenced
+by name without using the parameter expansion syntax.
+The value of a variable is evaluated as an arithmetic expression
+when it is referenced, or when a variable which has been given the
+<I>integer</I> attribute using <B>declare -i</B> is assigned a value.
+A null value evaluates to 0.
+A shell variable need not have its <I>integer</I> attribute
+turned on to be used in an expression.
+<P>
+
+Integer constants follow the C language definition, without suffixes or
+character constants.
+Constants with a leading 0 are interpreted as octal numbers.
+A leading 0x or 0X denotes hexadecimal.
+Otherwise, numbers take the form [<I>base#</I>]n, where the optional <I>base</I>
+is a decimal number between 2 and 64 representing the arithmetic
+base, and <I>n</I> is a number in that base.
+If <I>base#</I> is omitted, then base 10 is used.
+When specifying <I>n</I>,
+if a non-digit is required,

+
+Conditional expressions are used by the <B>[[</B> compound command and

+The <B>test</B> and <B>[</B> commands determine their behavior based on

+
+Expressions are formed from the following unary or binary primaries.
+<B>Bash</B> handles several filenames specially when they are used in

+If the operating system on which <B>bash</B> is running provides these

+If any <I>file</I> argument to one of the primaries is of the form

+<H3>SIMPLE COMMAND EXPANSION</H3>
+
+When a simple command is executed, the shell performs the following
+expansions, assignments, and redirections, from left to right, in
+the following order.
+<DL COMPACT>
+<DT>1.<DD>
+The words that the parser has marked as variable assignments (those
+preceding the command name) and redirections are saved for later
+processing.
+<DT>2.<DD>
+The words that are not variable assignments or redirections are
+expanded.  If any words remain after expansion, the first word
+is taken to be the name of the command and the remaining words are
+the arguments.
+<DT>3.<DD>
+Redirections are performed as described above under
+<FONT SIZE=-1><B>REDIRECTION</B>.
+
+</FONT>
+<DT>4.<DD>
+The text after the <B>=</B> in each variable assignment undergoes tilde
+expansion, parameter expansion, command substitution, arithmetic expansion,
+and quote removal before being assigned to the variable.
+</DL>
+<P>
+
+If no command name results, the variable assignments affect the current
+shell environment.
+In the case of such a command (one that consists only of assignment
+statements and redirections), assignment statements are performed before
+redirections.
+Otherwise, the variables are added to the environment
+of the executed command and do not affect the current shell environment.
+If any of the assignments attempts to assign a value to a readonly variable,
+an error occurs, and the command exits with a non-zero status.
+<P>
+
+If no command name results, redirections are performed, but do not
+affect the current shell environment.  A redirection error causes the
+command to exit with a non-zero status.
+<P>
+
+If there is a command name left after expansion, execution proceeds as
+described below.  Otherwise, the command exits.  If one of the expansions
+contained a command substitution, the exit status of the command is
+the exit status of the last command substitution performed.  If there
+were no command substitutions, the command exits with a status of zero.
+<A NAME="lbBY">&nbsp;</A>
+<H3>COMMAND EXECUTION</H3>
+
+After a command has been split into words, if it results in a
+simple command and an optional list of arguments, the following
+actions are taken.
+<P>
+
+If the command name contains no slashes, the shell attempts to
+locate it.  If there exists a shell function by that name, that
+function is invoked as described above in
+<FONT SIZE=-1><B>FUNCTIONS</B>.
+
+</FONT>
+If the name does not match a function, the shell searches for
+it in the list of shell builtins.  If a match is found, that
+builtin is invoked.
+<P>
+
+If the name is neither a shell function nor a builtin,
+and contains no slashes,
+<B>bash</B>
+
+searches each element of the
+<FONT SIZE=-1><B>PATH</B>
+
+</FONT>
+for a directory containing an executable file by that name.
+<B>Bash</B>
+
+uses a hash table to remember the full pathnames of executable
+files (see
+<B>hash</B>
+
+under
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below).
+A full search of the directories in
+<FONT SIZE=-1><B>PATH</B>
+
+</FONT>
+is performed only if the command is not found in the hash table.
+If the search is unsuccessful, the shell searches for a defined shell
+function named <B>command_not_found_handle</B>.
+If that function exists, it is invoked in a separate execution environment
+with the original command and
+the original command's arguments as its arguments, and the function's
+exit status becomes the exit status of that subshell.
+If that function is not defined, the shell prints an error
+message and returns an exit status of 127.
+<P>
+
+If the search is successful, or if the command name contains
+one or more slashes, the shell executes the named program in a
+separate execution environment.
+Argument 0 is set to the name given, and the remaining arguments
+to the command are set to the arguments given, if any.
+<P>
+
+If this execution fails because the file is not in executable
+format, and the file is not a directory, it is assumed to be
+a <I>shell script</I>, a file
+containing shell commands, and the shell creates a
+new instance of itself
+to execute it.
+This subshell reinitializes itself, so
+that the effect is as if a new shell had been invoked
+to handle the script, with the exception that the locations of
+commands remembered by the parent (see
+<B>hash</B>
+
+below under
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>)</FONT>
+are retained by the child.
+<P>
+
+If the program is a file beginning with
+<B>#!</B>,
+
+the remainder of the first line specifies an interpreter
+for the program.  The shell executes the
+specified interpreter on operating systems that do not
+handle this executable format themselves.  The arguments to the
+interpreter consist of a single optional argument following the
+interpreter name on the first line of the program, followed
+by the name of the program, followed by the command
+arguments, if any.
+<A NAME="lbBZ">&nbsp;</A>
+<H3>COMMAND EXECUTION ENVIRONMENT</H3>
+
+The shell has an <I>execution environment</I>, which consists of the
+following:
+<DL COMPACT>
+<DT>*<DD>
+open files inherited by the shell at invocation, as modified by
+redirections supplied to the <B>exec</B> builtin
+<DT>*<DD>
+the current working directory as set by <B>cd</B>, <B>pushd</B>, or
+<B>popd</B>, or inherited by the shell at invocation
+<DT>*<DD>
+the file creation mode mask as set by <B>umask</B> or inherited from
+the shell's parent
+<DT>*<DD>
+current traps set by <B>trap</B>
+<DT>*<DD>
+shell parameters that are set by variable assignment or with <B>set</B>
+or inherited from the shell's parent in the environment
+<DT>*<DD>
+shell functions defined during execution or inherited from the shell's
+parent in the environment
+<DT>*<DD>
+options enabled at invocation (either by default or with command-line
+arguments) or by <B>set</B>
+<DT>*<DD>
+options enabled by <B>shopt</B>
+<DT>*<DD>
+shell aliases defined with <B>alias</B>
+<DT>*<DD>
+various process IDs, including those of background jobs, the value
+of <B>$$</B>, and the value of
+<FONT SIZE=-1><B>PPID</B>
+
+</FONT>
+</DL>
+<P>
+
+When a simple command other than a builtin or shell function
+is to be executed, it
+is invoked in a separate execution environment that consists of
+the following.
+Unless otherwise noted, the values are inherited from the shell.
+
+<DL COMPACT>
+<DT>*<DD>
+the shell's open files, plus any modifications and additions specified
+by redirections to the command
+<DT>*<DD>
+the current working directory
+<DT>*<DD>
+the file creation mode mask
+<DT>*<DD>
+shell variables and functions marked for export, along with variables
+exported for the command, passed in the environment
+<DT>*<DD>
+traps caught by the shell are reset to the values inherited from the
+shell's parent, and traps ignored by the shell are ignored
+</DL>
+<P>
+
+A command invoked in this separate environment cannot affect the
+shell's execution environment.
+<P>
+
+A <I>subshell</I> is a copy of the shell process.
+<P>
+
+Command substitution, commands grouped with parentheses,
+and asynchronous commands are invoked in a
+subshell environment that is a duplicate of the shell environment,
+except that traps caught by the shell are reset to the values
+that the shell inherited from its parent at invocation.  Builtin
+commands that are invoked as part of a pipeline are also executed in a
+subshell environment.  Changes made to the subshell environment
+cannot affect the shell's execution environment.
+<P>
+
+Subshells spawned to execute command substitutions inherit the value of
+the <B>-e</B> option from the parent shell.  When not in <I>posix mode</I>,
+<B>bash</B> clears the <B>-e</B> option in such subshells.
+<P>
+
+If a command is followed by a <B>&amp;</B> and job control is not active, the
+default standard input for the command is the empty file <I>/dev/null</I>.
+Otherwise, the invoked command inherits the file descriptors of the calling
+shell as modified by redirections.
+<A NAME="lbCA">&nbsp;</A>
+<H3>ENVIRONMENT</H3>
+
+When a program is invoked it is given an array of strings
+called the
+<I>environment</I>.
+
+This is a list of
+<I>name</I>-<I>value</I> pairs, of the form
+<I>name</I>=value.
+
+<P>
+
+The shell provides several ways to manipulate the environment.
+On invocation, the shell scans its own environment and
+creates a parameter for each name found, automatically marking
+it for
+<I>export</I>
+
+to child processes.  Executed commands inherit the environment.
+The
+<B>export</B>
+
+and
+<B>declare -x</B>
+
+commands allow parameters and functions to be added to and
+deleted from the environment.  If the value of a parameter
+in the environment is modified, the new value becomes part
+of the environment, replacing the old.  The environment
+inherited by any executed command consists of the shell's
+initial environment, whose values may be modified in the shell,
+less any pairs removed by the
+<B>unset</B>
+
+command, plus any additions via the
+<B>export</B>
+
+and
+<B>declare -x</B>
+
+commands.
+<P>
+
+The environment for any
+<I>simple command</I>
+
+or function may be augmented temporarily by prefixing it with
+parameter assignments, as described above in
+<FONT SIZE=-1><B>PARAMETERS</B>.
+
+</FONT>
+These assignment statements affect only the environment seen
+by that command.
+<P>
+
+If the
+<B>-k</B>
+
+option is set (see the
+<B>set</B>
+
+builtin command below), then
+<I>all</I>
+
+parameter assignments are placed in the environment for a command,
+not just those that precede the command name.
+<P>
+
+When
+<B>bash</B>
+
+invokes an external command, the variable
+<B>_</B>
+
+is set to the full filename of the command and passed to that
+command in its environment.
+<A NAME="lbCB">&nbsp;</A>
+<H3>EXIT STATUS</H3>
+
+The exit status of an executed command is the value returned by the
+<I>waitpid</I> system call or equivalent function.  Exit statuses
+fall between 0 and 255, though, as explained below, the shell may
+use values above 125 specially.  Exit statuses from shell builtins and
+compound commands are also limited to this range.  Under certain
+circumstances, the shell will use special values to indicate specific
+failure modes.
+<P>
+
+For the shell's purposes, a command which exits with a
+zero exit status has succeeded.  An exit status of zero
+indicates success.  A non-zero exit status indicates failure.
+When a command terminates on a fatal signal <I>N</I>, <B>bash</B> uses
+the value of 128+<I>N</I> as the exit status.
+<P>
+
+If a command is not found, the child process created to
+execute it returns a status of 127.  If a command is found
+but is not executable, the return status is 126.
+<P>
+
+If a command fails because of an error during expansion or redirection,
+the exit status is greater than zero.
+<P>
+
+Shell builtin commands return a status of 0 (<I>true</I>) if
+successful, and non-zero (<I>false</I>) if an error occurs
+while they execute.
+All builtins return an exit status of 2 to indicate incorrect usage,
+generally invalid options or missing arguments.
+<P>
+
+The exit status of the last command is available in the special
+parameter $?.
+<P>
+
+<B>Bash</B> itself returns the exit status of the last command
+executed, unless a syntax error occurs, in which case it exits
+with a non-zero value.  See also the <B>exit</B> builtin
+command below.
+<A NAME="lbCC">&nbsp;</A>
+<H3>SIGNALS</H3>
+
+When <B>bash</B> is interactive, in the absence of any traps, it ignores
+<FONT SIZE=-1><B>SIGTERM</B>
+
+</FONT>
+(so that <B>kill 0</B> does not kill an interactive shell),
+and
+<FONT SIZE=-1><B>SIGINT</B>
+
+</FONT>
+is caught and handled (so that the <B>wait</B> builtin is interruptible).
+In all cases, <B>bash</B> ignores
+<FONT SIZE=-1><B>SIGQUIT</B>.
+
+</FONT>
+If job control is in effect,
+<B>bash</B>
+
+ignores
+<FONT SIZE=-1><B>SIGTTIN</B>,

+<FONT SIZE=-1><B>SIGTSTP</B>.
+
+</FONT>
+<P>
+
+Non-builtin commands run by <B>bash</B> have signal handlers
+set to the values inherited by the shell from its parent.
+When job control is not in effect, asynchronous commands
+ignore
+<FONT SIZE=-1><B>SIGINT</B>
+
+</FONT>
+and
+<FONT SIZE=-1><B>SIGQUIT</B>
+
+</FONT>
+in addition to these inherited handlers.
+Commands run as a result of command substitution ignore the
+keyboard-generated job control signals
+<FONT SIZE=-1><B>SIGTTIN</B>,
+
+</FONT>
+<FONT SIZE=-1><B>SIGTTOU</B>,
+
+</FONT>
+and
+<FONT SIZE=-1><B>SIGTSTP</B>.
+
+</FONT>
+<P>
+
+The shell exits by default upon receipt of a
+<FONT SIZE=-1><B>SIGHUP</B>.
+
+</FONT>
+Before exiting, an interactive shell resends the
+<FONT SIZE=-1><B>SIGHUP</B>
+
+</FONT>
+to all jobs, running or stopped.
+Stopped jobs are sent
+<FONT SIZE=-1><B>SIGCONT</B>
+
+</FONT>
+to ensure that they receive the
+<FONT SIZE=-1><B>SIGHUP</B>.
+
+</FONT>
+To prevent the shell from
+sending the signal to a particular job, it should be removed from the
+jobs table with the
+<B>disown</B>
+
+builtin (see
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below) or marked
+to not receive
+<FONT SIZE=-1><B>SIGHUP</B>
+
+</FONT>
+using
+<B>disown -h</B>.
+
+<P>
+
+If the
+<B>huponexit</B>
+
+shell option has been set with
+<B>shopt</B>,
+
+<B>bash</B>
+
+sends a
+<FONT SIZE=-1><B>SIGHUP</B>
+
+</FONT>
+to all jobs when an interactive login shell exits.
+<P>
+
+If <B>bash</B> is waiting for a command to complete and receives a signal
+for which a trap has been set, the trap will not be executed until
+the command completes.
+When <B>bash</B> is waiting for an asynchronous command via the <B>wait</B>
+builtin, the reception of a signal for which a trap has been set will
+cause the <B>wait</B> builtin to return immediately with an exit status
+greater than 128, immediately after which the trap is executed.
+<P>
+
+When job control is not enabled, and <B>bash</B> is waiting for a foreground
+command to complete, the shell receives keyboard-generated signals
+such as
+<FONT SIZE=-1><B>SIGINT</B>
+
+</FONT>
+(usually generated by <B>^C</B>) that users commonly intend to send
+to that command.
+This happens because the shell and the command are in the
+same process group as the terminal, and <B>^C</B> sends
+<FONT SIZE=-1><B>SIGINT</B>
+
+</FONT>
+to all processes in that process group.
+<P>
+
+When <B>bash</B> is running without job control enabled and receives 
+<FONT SIZE=-1><B>SIGINT</B>
+
+</FONT>
+while waiting for a foreground command, it waits until that foreground
+command terminates and then decides what to do about the
+<FONT SIZE=-1><B>SIGINT</B>:
+
+</FONT>
+<DL COMPACT>
+<DT>1.<DD>
+If the command terminates due to the
+<FONT SIZE=-1><B>SIGINT</B>,
+
+</FONT>
+<B>bash</B> concludes
+that the user meant to end the entire script, and acts on the
+<FONT SIZE=-1><B>SIGINT</B>
+
+</FONT>
+(e.g., by running a

+
+</FONT>
+trap or exiting itself);
+<DT>2.<DD>
+If the command does not terminate due to
+<FONT SIZE=-1><B>SIGINT</B>,
+
+</FONT>
+the program handled the
+<FONT SIZE=-1><B>SIGINT</B>
+
+</FONT>
+itself and did not treat it as a fatal signal.
+In that case, <B>bash</B> does not treat
+<FONT SIZE=-1><B>SIGINT</B>
+
+</FONT>
+as a fatal signal, either, instead assuming that the
+<FONT SIZE=-1><B>SIGINT</B>
+
+</FONT>
+was used as part of the program's normal operation
+(e.g., emacs uses it to abort editing
+commands) or deliberately discarded.
+However, <B>bash</B> will run any

+<A NAME="lbCD">&nbsp;</A>
+<H3>JOB CONTROL</H3>
+
+<I>Job control</I>
+
+refers to the ability to selectively stop (<I>suspend</I>)
+the execution of processes and continue (<I>resume</I>)
+their execution at a later point.  A user typically employs
+this facility via an interactive interface supplied jointly
+by the operating system kernel's terminal driver and
+<B>bash</B>.
+
+<P>
+
+The shell associates a
+<I>job</I>
+
+with each pipeline.  It keeps a table of currently executing
+jobs, which may be listed with the
+<B>jobs</B>
+
+command.  When
+<B>bash</B>
+
+starts a job asynchronously (in the
+<I>background</I>),
+
+it prints a line that looks like:
+<DL COMPACT><DT><DD>
+<P>
+
+[1] 25647
+</DL>
+
+<P>
+
+indicating that this job is job number 1 and that the process ID
+of the last process in the pipeline associated with this job is 25647.
+All of the processes in a single pipeline are members of the same job.
+<B>Bash</B>
+
+uses the
+<I>job</I>
+
+abstraction as the basis for job control.
+<P>
+
+To facilitate the implementation of the user interface to job
+control, the operating system maintains the notion of a <I>current terminal
+process group ID</I>.  Members of this process group (processes whose
+process group ID is equal to the current terminal process group ID)
+receive keyboard-generated signals such as
+<FONT SIZE=-1><B>SIGINT</B>.
+
+</FONT>
+These processes are said to be in the
+<I>foreground</I>.
+
+<I>Background</I>
+
+processes are those whose process group ID differs from the terminal's;
+such processes are immune to keyboard-generated signals.
+Only foreground processes are allowed to read from or, if the
+user so specifies with <TT>stty tostop</TT>, write to the
+terminal.
+Background processes which attempt to read from (write to when
+<TT>stty tostop</TT> is in effect) the
+terminal are sent a
+<FONT SIZE=-1><B>SIGTTIN (SIGTTOU)</B>
+
+</FONT>
+signal by the kernel's terminal driver,
+which, unless caught, suspends the process.
+<P>
+
+If the operating system on which
+<B>bash</B>
+
+is running supports
+job control,
+<B>bash</B>
+
+contains facilities to use it.
+Typing the
+<I>suspend</I>
+
+character (typically
+<B>^Z</B>,
+
+Control-Z) while a process is running
+causes that process to be stopped and returns control to
+<B>bash</B>.
+
+Typing the
+<I>delayed suspend</I>
+
+character (typically
+<B>^Y</B>,
+
+Control-Y) causes the process to be stopped when it
+attempts to read input from the terminal, and control to
+be returned to
+<B>bash</B>.
+
+The user may then manipulate the state of this job, using the
+<B>bg</B>
+
+command to continue it in the background, the
+<B>fg</B>
+
+command to continue it in the foreground, or
+the
+<B>kill</B>
+
+command to kill it.  A <B>^Z</B> takes effect immediately,
+and has the additional side effect of causing pending output
+and typeahead to be discarded.
+<P>
+
+There are a number of ways to refer to a job in the shell.
+The character
+<B>%</B>
+
+introduces a job specification (<I>jobspec</I>).  Job number
+<I>n</I>
+
+may be referred to as
+<B>%n</B>.
+
+A job may also be referred to using a prefix of the name used to
+start it, or using a substring that appears in its command line.
+For example,
+<B>%ce</B>
+
+refers to a stopped
+job whose command name begins with
+<B>ce</B>.
+
+If a prefix matches more than one job,
+<B>bash</B>
+
+reports an error.  Using
+<B>%?ce</B>,
+
+on the other hand, refers to any job containing the string
+<B>ce</B>
+
+in its command line.  If the substring matches more than one job,
+<B>bash</B>
+
+reports an error.  The symbols
+<B>%%</B>
+
+and
+<B>%+</B>
+
+refer to the shell's notion of the
+<I>current job</I>,
+
+which is the last job stopped while it was in
+the foreground or started in the background.
+The
+<I>previous job</I>
+
+may be referenced using
+<B>%-</B>.
+
+If there is only a single job, <B>%+</B> and <B>%-</B> can both be used
+to refer to that job.
+In output pertaining to jobs (e.g., the output of the
+<B>jobs</B>
+
+command), the current job is always flagged with a
+<B>+</B>,
+
+and the previous job with a
+<B>-</B>.
+
+A single % (with no accompanying job specification) also refers to the
+current job.
+<P>
+
+Simply naming a job can be used to bring it into the
+foreground:
+<B>%1</B>
+
+is a synonym for
+<B>``fg %1''</B>,
+bringing job 1 from the background into the foreground.
+Similarly,
+<B>``%1 &amp;''</B>
+
+resumes job 1 in the background, equivalent to
+<B>``bg %1''</B>.
+<P>
+
+The shell learns immediately whenever a job changes state.
+Normally,
+<B>bash</B>
+
+waits until it is about to print a prompt before reporting
+changes in a job's status so as to not interrupt
+any other output.  If the
+<B>-b</B>
+
+option to the
+<B>set</B>
+
+builtin command
+is enabled,
+<B>bash</B>
+
+reports such changes immediately.
+Any trap on
+<FONT SIZE=-1><B>SIGCHLD</B>
+
+</FONT>
+is executed for each child that exits.
+<P>
+
+If an attempt to exit
+<B>bash</B>
+
+is made while jobs are stopped (or, if the <B>checkjobs</B> shell option has
+been enabled using the <B>shopt</B> builtin, running), the shell prints a
+warning message, and, if the <B>checkjobs</B> option is enabled, lists the
+jobs and their statuses.
+The
+<B>jobs</B>
+
+command may then be used to inspect their status.
+If a second attempt to exit is made without an intervening command,
+the shell does not print another warning, and any stopped
+jobs are terminated.
+<P>
+
+When the shell is waiting for a job or process using the <B>wait</B>
+builtin, and job control is enabled, <B>wait</B> will return when the
+job changes state. The <B>-f</B> option causes <B>wait</B> to wait
+until the job or process terminates before returning.

+<H3>PROMPTING</H3>
+
+When executing interactively,
+<B>bash</B>
+
+displays the primary prompt
+<FONT SIZE=-1><B>PS1</B>
+
+</FONT>
+when it is ready to read a command, and the secondary prompt
+<FONT SIZE=-1><B>PS2</B>
+
+</FONT>
+when it needs more input to complete a command.
+<B>Bash</B>
+
+displays
+<FONT SIZE=-1><B>PS0</B>
+
+</FONT>
+after it reads a command but before executing it.
+<B>Bash</B>
+
+displays
+<FONT SIZE=-1><B>PS4</B>
+
+</FONT>
+as described above
+before tracing each command when the <B>-x</B> option is enabled.
+<B>Bash</B>
+
+allows these prompt strings to be customized by inserting a number of
+backslash-escaped special characters that are decoded as follows:
+<DL COMPACT><DT><DD>
+
+<DL COMPACT>
+<DT><B>\a</B>
+
+<DD>
+an ASCII bell character (07)
+<DT><B>\d</B>

+the <I>format</I> is passed to <I>strftime</I>(3) and the result is inserted
+into the prompt string; an empty <I>format</I> results in a locale-specific

+
+<P>
+
+The command number and the history number are usually different:
+the history number of a command is its position in the history
+list, which may include commands restored from the history file
+(see
+<FONT SIZE=-1><B>HISTORY</B>
+
+</FONT>
+below), while the command number is the position in the sequence
+of commands executed during the current shell session.
+After the string is decoded, it is expanded via
+parameter expansion, command substitution, arithmetic
+expansion, and quote removal, subject to the value of the
+<B>promptvars</B>
+
+shell option (see the description of the
+<B>shopt</B>
+
+command under
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below).
+This can have unwanted side effects if escaped portions of the string
+appear within command substitution or contain characters special to
+word expansion.
+<A NAME="lbCF">&nbsp;</A>
+<H3>READLINE</H3>
+
+This is the library that handles reading input when using an interactive
+shell, unless the
+<B>--noediting</B>
+
+option is given at shell invocation.
+Line editing is also used when using the <B>-e</B> option to the
+<B>read</B> builtin.
+By default, the line editing commands are similar to those of Emacs.
+A vi-style line editing interface is also available.
+Line editing can be enabled at any time using the
+<B>-o emacs</B>
+
+or
+<B>-o vi</B>
+
+options to the
+<B>set</B>
+
+builtin (see
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below).
+To turn off line editing after the shell is running, use the
+<B>+o emacs</B>
+
+or
+<B>+o vi</B>
+
+options to the
+<B>set</B>
+
+builtin.
+<A NAME="lbCG">&nbsp;</A>
+<H4>Readline Notation</H4>
+
+In this section, the Emacs-style notation is used to denote
+keystrokes.  Control keys are denoted by C-<I>key</I>, e.g., C-n
+means Control-N.  Similarly,
+<I>meta</I>
+
+keys are denoted by M-<I>key</I>, so M-x means Meta-X.  (On keyboards
+without a
+<I>meta</I>
+
+key, M-<I>x</I> means ESC <I>x</I>, i.e., press the Escape key
+then the
+<I>x</I>
+
+key.  This makes ESC the <I>meta prefix</I>.
+The combination M-C-<I>x</I> means ESC-Control-<I>x</I>,
+or press the Escape key
+then hold the Control key while pressing the
+<I>x</I>
+
+key.)
+<P>
+
+Readline commands may be given numeric
+<I>arguments</I>,
+
+which normally act as a repeat count.
+Sometimes, however, it is the sign of the argument that is significant.
+Passing a negative argument to a command that acts in the forward
+direction (e.g., <B>kill-line</B>) causes that command to act in a
+backward direction.
+Commands whose behavior with arguments deviates from this are noted
+below.
+<P>
+
+When a command is described as <I>killing</I> text, the text
+deleted is saved for possible future retrieval
+(<I>yanking</I>).  The killed text is saved in a
+<I>kill ring</I>.  Consecutive kills cause the text to be
+accumulated into one unit, which can be yanked all at once.
+Commands which do not kill text separate the chunks of text
+on the kill ring.
+<A NAME="lbCH">&nbsp;</A>
+<H4>Readline Initialization</H4>
+
+Readline is customized by putting commands in an initialization
+file (the <I>inputrc</I> file).
+The name of this file is taken from the value of the
+<FONT SIZE=-1><B>INPUTRC</B>
+
+</FONT>
+variable.  If that variable is unset, the default is
+<A HREF="file:~/.inputrc"><I>~/.inputrc</I></A>.
+
+If that file  does not exist or cannot be read, the ultimate default is
+<A HREF="file:/etc/inputrc"><I>/etc/inputrc</I></A>.
+
+When a program which uses the readline library starts up, the
+initialization file is read, and the key bindings and variables
+are set.
+There are only a few basic constructs allowed in the
+readline initialization file.
+Blank lines are ignored.
+Lines beginning with a <B>#</B> are comments.
+Lines beginning with a <B>$</B> indicate conditional constructs.
+Other lines denote key bindings and variable settings.
+<P>
+
+The default key-bindings may be changed with an
+<I>inputrc</I>
+
+file.
+Other programs that use this library may add their own commands
+and bindings.
+<P>
+
+For example, placing
+<DL COMPACT><DT><DD>
+<P>
+
+M-Control-u: universal-argument
+</DL>
+
+or
+<DL COMPACT><DT><DD>
+C-Meta-u: universal-argument
+</DL>
+
+into the
+<I>inputrc</I>
+
+would make M-C-u execute the readline command
+<I>universal-argument</I>.
+
+<P>
+
+The following symbolic character names are recognized:
+<I>RUBOUT</I>,
+
+<I>DEL</I>,
+
+<I>ESC</I>,
+
+<I>LFD</I>,
+
+<I>NEWLINE</I>,
+
+<I>RET</I>,
+
+<I>RETURN</I>,
+
+<I>SPC</I>,
+
+<I>SPACE</I>,
+
+and
+<I>TAB</I>.
+
+<P>
+
+In addition to command names, readline allows keys to be bound
+to a string that is inserted when the key is pressed (a <I>macro</I>).
+<A NAME="lbCI">&nbsp;</A>
+<H4>Readline Key Bindings</H4>
+
+The syntax for controlling key bindings in the
+<I>inputrc</I>
+
+file is simple.  All that is required is the name of the
+command or the text of a macro and a key sequence to which
+it should be bound.  The name may be specified in one of two ways:
+as a symbolic key name, possibly with <I>Meta-</I> or <I>Control-</I>
+prefixes, or as a key sequence.
+<P>
+
+When using the form <B>keyname</B>:<I>function-name</I> or <I>macro</I>,
+<I>keyname</I>
+
+is the name of a key spelled out in English.  For example:
+<P>
+<DL COMPACT><DT><DD>
+Control-u: universal-argument
+<BR>
+
+Meta-Rubout: backward-kill-word
+<BR>
+
+Control-o: &quot;&gt; output&quot;
+</DL>
+
+<P>
+
+In the above example,
+<I>C-u</I>
+
+is bound to the function
+<B>universal-argument</B>,
+
+<I>M-DEL</I>
+
+is bound to the function
+<B>backward-kill-word</B>,
+
+and
+<I>C-o</I>
+
+is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+<TT>&gt; output</TT>
+
+into the line).
+<P>
+
+In the second form, <B>&quot;keyseq&quot;</B>:<I>function-name</I> or <I>macro</I>,
+<B>keyseq</B>
+
+differs from
+<B>keyname</B>
+
+above in that strings denoting
+an entire key sequence may be specified by placing the sequence
+within double quotes.  Some GNU Emacs style key escapes can be
+used, as in the following example, but the symbolic character names
+are not recognized.
+<P>
+<DL COMPACT><DT><DD>
+&quot;\C-u&quot;: universal-argument
+<BR>
+
+&quot;\C-x\C-r&quot;: re-read-init-file
+<BR>
+
+&quot;\e[11~&quot;: &quot;Function Key 1&quot;
+</DL>
+
+<P>
+
+In this example,
+<I>C-u</I>
+
+is again bound to the function
+<B>universal-argument</B>.
+
+<I>C-x C-r</I>
+
+is bound to the function
+<B>re-read-init-file</B>,
+
+and
+<I>ESC [ 1 1 ~</I>
+
+is bound to insert the text
+<TT>Function Key 1</TT>.
+
+<P>
+
+The full set of GNU Emacs style escape sequences is
+<DL COMPACT><DT><DD>
+
+<DL COMPACT>
+<DT><B>\C-</B>
+
+<DD>
+control prefix
+<DT><B>\M-</B>
+

+
+<DD>

+</DL></DL>
+
+
+<P>
+
+In addition to the GNU Emacs style escape sequences, a second
+set of backslash escapes is available:
+<DL COMPACT><DT><DD>

+
+<DD>
+the eight-bit character whose value is the hexadecimal value <I>HH</I>
+(one or two hex digits)
+</DL></DL>
+
+
+<P>
+
+When entering the text of a macro, single or double quotes must
+be used to indicate a macro definition.
+Unquoted text is assumed to be a function name.
+In the macro body, the backslash escapes described above are expanded.
+Backslash will quote any other character in the macro text,
+including &quot; and aq.
+<P>
+
+<B>Bash</B>
+
+allows the current readline key bindings to be displayed or modified

+<A NAME="lbCJ">&nbsp;</A>
+<H4>Readline Variables</H4>
+
+Readline has variables that can be used to further customize its
+behavior.  A variable may be set in the
+<I>inputrc</I>
+
+file with a statement of the form
+<DL COMPACT><DT><DD>
+<P>
+
+<B>set</B> <I>variable-name</I> <I>value</I>
+</DL>
+
+or using the <B>bind</B> builtin command (see
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below).
+<P>
+
+Except where noted, readline variables can take the values
+<B>On</B>
+
+or
+<B>Off</B>
+
+(without regard to case).
+Unrecognized variable names are ignored.
+When a variable value is read, empty or null values, &quot;on&quot; (case-insensitive),
+and &quot;1&quot; are equivalent to <B>On</B>.  All other values are equivalent to
+<B>Off</B>.
+The variables and their default values are:
+<P>
+
+
+<DL COMPACT>
+<DT><B>active-region-start-color   </B>
+
+<DD>
+A string variable that controls the text color and background when displaying
+the text in the active region (see the description of
+<B>enable-active-region</B> below).
+This string must not take up any physical character positions on the display,
+so it should consist only of terminal escape sequences.
+It is output to the terminal before displaying the text in the active region.
+This variable is reset to the default value whenever the terminal type changes.
+The default value is the string that puts the terminal in standout mode,
+as obtained from the terminal's terminfo description.
+A sample value might be <TT>&quot;\e[01;33m&quot;</TT>.
+<DT><B>active-region-end-color     </B>
+
+<DD>
+A string variable that &quot;undoes&quot; the effects of <B>active-region-start-color</B> 
+and restores &quot;normal&quot; terminal display appearance after displaying text
+in the active region.
+This string must not take up any physical character positions on the display,
+so it should consist only of terminal escape sequences.
+It is output to the terminal after displaying the text in the active region.
+This variable is reset to the default value whenever the terminal type changes.
+The default value is the string that restores the terminal from standout mode,
+as obtained from the terminal's terminfo description.
+A sample value might be <TT>&quot;\e[0m&quot;</TT>.
+<DT><B>bell-style (audible)</B>
+
+<DD>
+Controls what happens when readline wants to ring the terminal bell.
+If set to <B>none</B>, readline never rings the bell.  If set to
+<B>visible</B>, readline uses a visible bell if one is available.
+If set to <B>audible</B>, readline attempts to ring the terminal's bell.
+<DT><B>bind-tty-special-chars (On)</B>
+
+<DD>
+If set to <B>On</B>, readline attempts to bind the control characters
+treated specially by the kernel's terminal driver to their readline
+equivalents.
+<DT><B>blink-matching-paren (Off)</B>
+
+<DD>
+If set to <B>On</B>, readline attempts to briefly move the cursor to an
+opening parenthesis when a closing parenthesis is inserted.
+<DT><B>colored-completion-prefix (Off)</B>
+
+<DD>
+If set to <B>On</B>, when listing completions, readline displays the
+common prefix of the set of possible completions using a different color.
+The color definitions are taken from the value of the <B>LS_COLORS</B>
+environment variable.
+If there is a color definition in <B>$LS_COLORS</B> for the custom suffix
+&quot;readline-colored-completion-prefix&quot;, readline uses this color for
+the common prefix instead of its default.
+<DT><B>colored-stats (Off)</B>
+
+<DD>
+If set to <B>On</B>, readline displays possible completions using different
+colors to indicate their file type.
+The color definitions are taken from the value of the <B>LS_COLORS</B>
+environment variable.
+<DT><B>comment-begin (``#'')</B>
+
+<DD>
+The string that is inserted when the readline
+<B>insert-comment</B>
+
+command is executed.
+This command is bound to
+<B>M-#</B>
+
+in emacs mode and to
+<B>#</B>
+
+in vi command mode.
+<DT><B>completion-display-width (-1)</B>
+
+<DD>
+The number of screen columns used to display possible matches
+when performing completion.
+The value is ignored if it is less than 0 or greater than the terminal
+screen width.
+A value of 0 will cause matches to be displayed one per line.
+The default value is -1.
+<DT><B>completion-ignore-case (Off)</B>
+
+<DD>
+If set to <B>On</B>, readline performs filename matching and completion
+in a case-insensitive fashion.
+<DT><B>completion-map-case (Off)</B>
+
+<DD>
+If set to <B>On</B>, and <B>completion-ignore-case</B> is enabled, readline
+treats hyphens (<I>-</I>) and underscores (<I>_</I>) as equivalent when
+performing case-insensitive filename matching and completion.
+<DT><B>completion-prefix-display-length (0)</B>
+
+<DD>
+The length in characters of the common prefix of a list of possible
+completions that is displayed without modification.  When set to a
+value greater than zero, common prefixes longer than this value are
+replaced with an ellipsis when displaying possible completions.
+<DT><B>completion-query-items (100)</B>
+
+<DD>
+This determines when the user is queried about viewing
+the number of possible completions
+generated by the <B>possible-completions</B> command.
+It may be set to any integer value greater than or equal to zero.
+If the number of possible completions is greater than
+or equal to the value of this variable,
+readline will ask whether or not the user wishes to view them;
+otherwise they are simply listed on the terminal.
+A zero value means readline should never ask; negative values are
+treated as zero.
+<DT><B>convert-meta (On)</B>
+
+<DD>
+If set to <B>On</B>, readline will convert characters with the
+eighth bit set to an ASCII key sequence
+by stripping the eighth bit and prefixing an
+escape character (in effect, using escape as the <I>meta prefix</I>).
+The default is <I>On</I>, but readline will set it to <I>Off</I> if the
+locale contains eight-bit characters.
+This variable is dependent on the <B>LC_CTYPE</B> locale category, and 
+may change if the locale is changed.
+<DT><B>disable-completion (Off)</B>
+
+<DD>
+If set to <B>On</B>, readline will inhibit word completion.  Completion
+characters will be inserted into the line as if they had been
+mapped to <B>self-insert</B>.
+<DT><B>echo-control-characters (On)</B>
+
+<DD>
+When set to <B>On</B>, on operating systems that indicate they support it,
+readline echoes a character corresponding to a signal generated from the
+keyboard.
+<DT><B>editing-mode (emacs)</B>
+
+<DD>
+Controls whether readline begins with a set of key bindings similar
+to <I>Emacs</I> or <I>vi</I>.
+<B>editing-mode</B>
+
+can be set to either
+<B>emacs</B>
+
+or
+<B>vi</B>.
+
+<DT><B>emacs-mode-string (@)</B>
+
+<DD>
+If the <I>show-mode-in-prompt</I> variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when emacs editing mode is active.  The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the \1 and \2 escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+<DT><B>enable-active-region (On)</B>
+
+<DD>
+The <I>point</I> is the current cursor position, and <I>mark</I> refers  
+to a saved cursor position.   
+The text between the point and mark is referred to as the <I>region</I>.  
+When this variable is set to <I>On</I>, readline allows certain commands
+to designate the region as <I>active</I>.  
+When the region is active, readline highlights the text in the region using
+the value of the <B>active-region-start-color</B>, which defaults to the
+string that enables
+the terminal's standout mode.
+The active region shows the text inserted by bracketed-paste and any
+matching text found by incremental and non-incremental history searches.
+<DT><B>enable-bracketed-paste (On)</B>
+
+<DD>
+When set to <B>On</B>, readline configures the terminal to insert each
+paste into the editing buffer as a single string of characters, instead
+of treating each character as if it had been read from the keyboard.
+This prevents readline from executing any editing commands bound to key
+sequences appearing in the pasted text.
+<DT><B>enable-keypad (Off)</B>
+
+<DD>
+When set to <B>On</B>, readline will try to enable the application
+keypad when it is called.  Some systems need this to enable the
+arrow keys.
+<DT><B>enable-meta-key (On)</B>
+
+<DD>
+When set to <B>On</B>, readline will try to enable any meta modifier
+key the terminal claims to support when it is called.  On many terminals,
+the meta key is used to send eight-bit characters.
+<DT><B>expand-tilde (Off)</B>
+
+<DD>
+If set to <B>On</B>, tilde expansion is performed when readline
+attempts word completion.
+<DT><B>history-preserve-point (Off)</B>
+
+<DD>
+If set to <B>On</B>, the history code attempts to place point at the
+same location on each history line retrieved with <B>previous-history</B>
+or <B>next-history</B>.
+<DT><B>history-size (unset)</B>
+
+<DD>
+Set the maximum number of history entries saved in the history list.
+If set to zero, any existing history entries are deleted and no new entries
+are saved.
+If set to a value less than zero, the number of history entries is not
+limited.
+By default, the number of history entries is set to the value of the
+<B>HISTSIZE</B> shell variable.
+If an attempt is made to set <I>history-size</I> to a non-numeric value,
+the maximum number of history entries will be set to 500.
+<DT><B>horizontal-scroll-mode (Off)</B>
+
+<DD>
+When set to <B>On</B>, makes readline use a single line for display,
+scrolling the input horizontally on a single screen line when it
+becomes longer than the screen width rather than wrapping to a new line.
+This setting is automatically enabled for terminals of height 1.
+<DT><B>input-meta (Off)</B>
+
+<DD>
+If set to <B>On</B>, readline will enable eight-bit input (that is,
+it will not strip the eighth bit from the characters it reads),
+regardless of what the terminal claims it can support.  The name
+<B>meta-flag</B>
+
+is a synonym for this variable.
+The default is <I>Off</I>, but readline will set it to <I>On</I> if the
+locale contains eight-bit characters.
+This variable is dependent on the <B>LC_CTYPE</B> locale category, and 
+may change if the locale is changed.
+<DT><B>isearch-terminators (``C-[C-J'')</B>
+
+<DD>
+The string of characters that should terminate an incremental
+search without subsequently executing the character as a command.
+If this variable has not been given a value, the characters
+<I>ESC</I> and <I>C-J</I> will terminate an incremental search.
+<DT><B>keymap (emacs)</B>
+
+<DD>
+Set the current readline keymap.  The set of valid keymap names is
+<I>emacs, emacs-standard, emacs-meta, emacs-ctlx, vi,
+vi-command</I>, and
+<I>vi-insert</I>.
+
+<I>vi</I> is equivalent to <I>vi-command</I>; <I>emacs</I> is
+equivalent to <I>emacs-standard</I>.  The default value is
+<I>emacs</I>;
+
+the value of
+<B>editing-mode</B>
+
+also affects the default keymap.
+<DT><B>keyseq-timeout (500)</B>
+
+<DD>
+Specifies the duration <I>readline</I> will wait for a character when reading an
+ambiguous key sequence (one that can form a complete key sequence using
+the input read so far, or can take additional input to complete a longer
+key sequence).
+If no input is received within the timeout, <I>readline</I> will use the shorter
+but complete key sequence.
+The value is specified in milliseconds, so a value of 1000 means that
+<I>readline</I> will wait one second for additional input.
+If this variable is set to a value less than or equal to zero, or to a
+non-numeric value, <I>readline</I> will wait until another key is pressed to
+decide which key sequence to complete.
+<DT><B>mark-directories (On)</B>
+
+<DD>
+If set to <B>On</B>, completed directory names have a slash
+appended.
+<DT><B>mark-modified-lines (Off)</B>
+
+<DD>
+If set to <B>On</B>, history lines that have been modified are displayed
+with a preceding asterisk (<B>*</B>).
+<DT><B>mark-symlinked-directories (Off)</B>
+
+<DD>
+If set to <B>On</B>, completed names which are symbolic links to directories
+have a slash appended (subject to the value of
+<B>mark-directories</B>).
+<DT><B>match-hidden-files (On)</B>
+
+<DD>
+This variable, when set to <B>On</B>, causes readline to match files whose
+names begin with a `.' (hidden files) when performing filename
+completion.
+If set to <B>Off</B>, the leading `.' must be
+supplied by the user in the filename to be completed.
+<DT><B>menu-complete-display-prefix (Off)</B>
+
+<DD>
+If set to <B>On</B>, menu completion displays the common prefix of the
+list of possible completions (which may be empty) before cycling through
+the list.
+<DT><B>output-meta (Off)</B>
+
+<DD>
+If set to <B>On</B>, readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence.
+The default is <I>Off</I>, but readline will set it to <I>On</I> if the
+locale contains eight-bit characters.
+This variable is dependent on the <B>LC_CTYPE</B> locale category, and 
+may change if the locale is changed.
+<DT><B>page-completions (On)</B>
+
+<DD>
+If set to <B>On</B>, readline uses an internal <I>more</I>-like pager
+to display a screenful of possible completions at a time.
+<DT><B>print-completions-horizontally (Off)</B>
+
+<DD>
+If set to <B>On</B>, readline will display completions with matches
+sorted horizontally in alphabetical order, rather than down the screen.
+<DT><B>revert-all-at-newline (Off)</B>
+
+<DD>
+If set to <B>On</B>, readline will undo all changes to history lines
+before returning when <B>accept-line</B> is executed.  By default,
+history lines may be modified and retain individual undo lists across
+calls to <B>readline</B>.
+<DT><B>show-all-if-ambiguous (Off)</B>
+
+<DD>
+This alters the default behavior of the completion functions.  If
+set to
+<B>On</B>,
+
+words which have more than one possible completion cause the
+matches to be listed immediately instead of ringing the bell.
+<DT><B>show-all-if-unmodified (Off)</B>
+
+<DD>
+This alters the default behavior of the completion functions in
+a fashion similar to <B>show-all-if-ambiguous</B>.
+If set to
+<B>On</B>,
+
+words which have more than one possible completion without any
+possible partial completion (the possible completions don't share
+a common prefix) cause the matches to be listed immediately instead
+of ringing the bell.
+<DT><B>show-mode-in-prompt (Off)</B>
+
+<DD>
+If set to <B>On</B>, add a string to the beginning of the prompt
+indicating the editing mode: emacs, vi command, or vi insertion.
+The mode strings are user-settable (e.g., <I>emacs-mode-string</I>).
+<DT><B>skip-completed-text (Off)</B>
+
+<DD>
+If set to <B>On</B>, this alters the default completion behavior when
+inserting a single match into the line.  It's only active when
+performing completion in the middle of a word.  If enabled, readline
+does not insert characters from the completion that match characters
+after point in the word being completed, so portions of the word
+following the cursor are not duplicated.
+<DT><B>vi-cmd-mode-string ((cmd))</B>
+
+<DD>
+If the <I>show-mode-in-prompt</I> variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when vi editing mode is active and in command mode.
+The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the \1 and \2 escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+<DT><B>vi-ins-mode-string ((ins))</B>
+
+<DD>
+If the <I>show-mode-in-prompt</I> variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when vi editing mode is active and in insertion mode.
+The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the \1 and \2 escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+<DT><B>visible-stats (Off)</B>
+
+<DD>
+If set to <B>On</B>, a character denoting a file's type as reported
+by <I>stat</I>(2) is appended to the filename when listing possible
+completions.

+<H4>Readline Conditional Constructs</H4>
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests.  There are four parser directives used.
+<DL COMPACT>
+<DT><B>$if</B><DD>
+The
+<B>$if</B>
+
+construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+readline.  The text of the test, after any comparison operator,
+<BR>&nbsp;extends&nbsp;to&nbsp;the&nbsp;end&nbsp;of&nbsp;the&nbsp;line;
+unless otherwise noted, no characters are required to isolate it.
+<DL COMPACT><DT><DD>
+<DL COMPACT>
+<DT><B>mode</B><DD>
+The <B>mode=</B> form of the <B>$if</B> directive is used to test
+whether readline is in emacs or vi mode.
+This may be used in conjunction
+with the <B>set keymap</B> command, for instance, to set bindings in
+the <I>emacs-standard</I> and <I>emacs-ctlx</I> keymaps only if
+readline is starting out in emacs mode.
+<DT><B>term</B><DD>
+The <B>term=</B> form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys.  The word on the right side of the
+<B>=</B>
+
+is tested against both the full name of the terminal and the portion
+of the terminal name before the first <B>-</B>.  This allows
+<I>sun</I>
+
+to match both
+<I>sun</I>
+
+and
+<I>sun-cmd</I>,
+
+for instance.
+<DT><B>version</B><DD>
+The <B>version</B> test may be used to perform comparisons against
+specific readline versions.
+The <B>version</B> expands to the current readline version.
+The set of comparison operators includes
+<B>=</B>,
+
+(and
+<B>==</B>),
+
+<B>!=</B>,
+
+<B>&lt;=</B>,
+
+<B>&gt;=</B>,
+
+<B>&lt;</B>,
+
+and
+<B>&gt;</B>.
+
+The version number supplied on the right side of the operator consists
+of a major version number, an optional decimal point, and an optional
+minor version (e.g., <B>7.1</B>). If the minor version is omitted, it
+is assumed to be <B>0</B>.
+The operator may be separated from the string <B>version</B>
+and from the version number argument by whitespace.
+<DT><B>application</B><DD>
+The <B>application</B> construct is used to include
+application-specific settings.  Each program using the readline
+library sets the <I>application name</I>, and an initialization
+file can test for a particular value.
+This could be used to bind key sequences to functions useful for
+a specific program.  For instance, the following command adds a
+key sequence that quotes the current or previous word in <B>bash</B>:
+<P>
+<DL COMPACT><DT><DD>
+<PRE>
+<B>$if</B> Bash
+# Quote the current or previous word
+&quot;\C-xq&quot;: &quot;\eb\&quot;\ef\&quot;&quot;
+<B>$endif</B>
+</PRE>
+
+</DL>
+
+<DT><I>variable</I><DD>
+The <I>variable</I> construct provides simple equality tests for readline
+variables and values.
+The permitted comparison operators are <I>=</I>, <I>==</I>, and <I>!=</I>.
+The variable name must be separated from the comparison operator by
+whitespace; the operator may be separated from the value on the right hand
+side by whitespace.
+Both string and boolean variables may be tested. Boolean variables must be
+tested against the values <I>on</I> and <I>off</I>.
+</DL></DL>
+
+<DT><B>$endif</B><DD>
+This command, as seen in the previous example, terminates an
+<B>$if</B> command.
+<DT><B>$else</B><DD>
+Commands in this branch of the <B>$if</B> directive are executed if
+the test fails.
+<DT><B>$include</B><DD>
+This directive takes a single filename as an argument and reads commands
+and bindings from that file.  For example, the following directive
+would read <A HREF="file:/etc/inputrc"><I>/etc/inputrc</I></A>:
+<P>
+<DL COMPACT><DT><DD>
+<PRE>
+<B>$include</B>  <A HREF="file:/etc/inputrc"><I>/etc/inputrc</I></A>
+</PRE>
+
+</DL>
+

+<A NAME="lbCL">&nbsp;</A>
+<H4>Searching</H4>
+
+Readline provides commands for searching through the command history
+(see
+<FONT SIZE=-1><B>HISTORY</B>
+
+</FONT>
+below) for lines containing a specified string.
+There are two search modes:
+<I>incremental</I>
+
+and
+<I>non-incremental</I>.
+
+<P>
+
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+The characters present in the value of the <B>isearch-terminators</B>
+variable are used to terminate an incremental search.
+If that variable has not been assigned a value the Escape and
+Control-J characters will terminate an incremental search.
+Control-G will abort an incremental search and restore the original
+line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+<P>
+
+To find other matching entries in the history list, type Control-S or
+Control-R as appropriate.
+This will search backward or forward in the history for the next
+entry matching the search string typed so far.
+Any other key sequence bound to a readline command will terminate
+the search and execute that command.
+For instance, a <I>newline</I> will terminate the search and accept
+the line, thereby executing the command from the history list.
+<P>
+
+Readline remembers the last incremental search string.  If two
+Control-Rs are typed without any intervening characters defining a
+new search string, any remembered search string is used.
+<P>
+
+Non-incremental searches read the entire search string before starting
+to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.
+<A NAME="lbCM">&nbsp;</A>
+<H4>Readline Command Names</H4>
+
+The following is a list of the names of the commands and the default
+key sequences to which they are bound.
+Command names without an accompanying key sequence are unbound by default.
+In the following descriptions, <I>point</I> refers to the current cursor
+position, and <I>mark</I> refers to a cursor position saved by the
+<B>set-mark</B> command.
+The text between the point and mark is referred to as the <I>region</I>.

+
+
+<DL COMPACT>
+<DT><B></B><I>end-of-file</I> (usually C-d)
+
+<DD>
+The character indicating end-of-file as set, for example, by
+<TT>stty</TT>.
+
+If this character is read when there are no characters
+on the line, and point is at the beginning of the line, readline
+interprets it as the end of input and returns
+<FONT SIZE=-1><B>EOF</B>.
+
+</FONT>
+<DT><B>delete-char (C-d)</B>
+
+<DD>
+Delete the character at point.
+If this function is bound to the
+same character as the tty <B>EOF</B> character, as <B>C-d</B>
+commonly is, see above for the effects.
+<DT><B>backward-delete-char (Rubout)</B>
+
+<DD>
+Delete the character behind the cursor.  When given a numeric argument,
+save the deleted text on the kill ring.
+<DT><B>forward-backward-delete-char</B>
+
+<DD>
+Delete the character under the cursor, unless the cursor is at the
+end of the line, in which case the character behind the cursor is
+deleted.
+<DT><B>quoted-insert (C-q, C-v)</B>
+
+<DD>
+Add the next character typed to the line verbatim.  This is
+how to insert characters like <B>C-q</B>, for example.
+<DT><B>tab-insert (C-v TAB)</B>
+
+<DD>
+Insert a tab character.
+<DT><B>self-insert (a,&nbsp;b,&nbsp;A,&nbsp;1,&nbsp;!,&nbsp;...)</B>
+
+<DD>
+Insert the character typed.
+<DT><B>transpose-chars (C-t)</B>
+
+<DD>
+Drag the character before point forward over the character at point,
+moving point forward as well.
+If point is at the end of the line, then this transposes
+the two characters before point.
+Negative arguments have no effect.
+<DT><B>transpose-words (M-t)</B>
+
+<DD>
+Drag the word before point past the word after point,
+moving point over that word as well.
+If point is at the end of the line, this transposes
+the last two words on the line.
+<DT><B>upcase-word (M-u)</B>
+
+<DD>
+Uppercase the current (or following) word.  With a negative argument,
+uppercase the previous word, but do not move point.
+<DT><B>downcase-word (M-l)</B>
+
+<DD>
+Lowercase the current (or following) word.  With a negative argument,
+lowercase the previous word, but do not move point.
+<DT><B>capitalize-word (M-c)</B>
+
+<DD>
+Capitalize the current (or following) word.  With a negative argument,
+capitalize the previous word, but do not move point.
+<DT><B>overwrite-mode</B>
+
+<DD>
+Toggle overwrite mode.  With an explicit positive numeric argument,
+switches to overwrite mode.  With an explicit non-positive numeric
+argument, switches to insert mode.  This command affects only
+<B>emacs</B> mode; <B>vi</B> mode does overwrite differently.
+Each call to <I>readline()</I> starts in insert mode.
+In overwrite mode, characters bound to <B>self-insert</B> replace
+the text at point rather than pushing the text to the right.
+Characters bound to <B>backward-delete-char</B> replace the character
+before point with a space.  By default, this command is unbound.

+<H4>Programmable Completion</H4>
+
+When word completion is attempted for an argument to a command for
+which a completion specification (a <I>compspec</I>) has been defined
+using the <B>complete</B> builtin (see
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below), the programmable completion facilities are invoked.
+<P>
+
+First, the command name is identified.
+If the command word is the empty string (completion attempted at the
+beginning of an empty line), any compspec defined with
+the <B>-E</B> option to <B>complete</B> is used.
+If a compspec has been defined for that command, the
+compspec is used to generate the list of possible completions for the word.
+If the command word is a full pathname, a compspec for the full
+pathname is searched for first.
+If no compspec is found for the full pathname, an attempt is made to
+find a compspec for the portion following the final slash.
+If those searches do not result in a compspec, any compspec defined with
+the <B>-D</B> option to <B>complete</B> is used as the default.
+If there is no default compspec, <B>bash</B> attempts alias expansion
+on the command word as a final resort, and attempts to find a compspec
+for the command word from any successful expansion.
+<P>
+
+Once a compspec has been found, it is used to generate the list of
+matching words.
+If a compspec is not found, the default <B>bash</B> completion as
+described above under <B>Completing</B> is performed.
+<P>
+
+First, the actions specified by the compspec are used.
+Only matches which are prefixed by the word being completed are
+returned.
+When the
+<B>-f</B>
+
+or
+<B>-d</B>
+
+option is used for filename or directory name completion, the shell
+variable
+<FONT SIZE=-1><B>FIGNORE</B>
+
+</FONT>
+is used to filter the matches.
+<P>
+
+Any completions specified by a pathname expansion pattern to the
+<B>-G</B> option are generated next.
+The words generated by the pattern need not match the word
+being completed.
+The
+<FONT SIZE=-1><B>GLOBIGNORE</B>
+
+</FONT>
+shell variable is not used to filter the matches, but the
+<FONT SIZE=-1><B>FIGNORE</B>
+
+</FONT>
+variable is used.
+<P>
+
+Next, the string specified as the argument to the <B>-W</B> option
+is considered.
+The string is first split using the characters in the
+<FONT SIZE=-1><B>IFS</B>
+
+</FONT>
+special variable as delimiters.
+Shell quoting is honored.
+Each word is then expanded using
+brace expansion, tilde expansion, parameter and variable expansion,
+command substitution, and arithmetic expansion,
+as described above under
+<FONT SIZE=-1><B>EXPANSION</B>.
+
+</FONT>
+The results are split using the rules described above under
+<B>Word Splitting</B>.
+The results of the expansion are prefix-matched against the word being
+completed, and the matching words become the possible completions.
+<P>
+
+After these matches have been generated, any shell function or command
+specified with the <B>-F</B> and <B>-C</B> options is invoked.
+When the command or function is invoked, the
+<FONT SIZE=-1><B>COMP_LINE</B>,
+
+</FONT>
+<FONT SIZE=-1><B>COMP_POINT</B>,
+
+</FONT>
+<FONT SIZE=-1><B>COMP_KEY</B>,
+
+</FONT>
+and
+<FONT SIZE=-1><B>COMP_TYPE</B>
+
+</FONT>
+variables are assigned values as described above under
+<B>Shell Variables</B>.
+If a shell function is being invoked, the
+<FONT SIZE=-1><B>COMP_WORDS</B>
+
+</FONT>
+and
+<FONT SIZE=-1><B>COMP_CWORD</B>
+
+</FONT>
+variables are also set.
+When the function or command is invoked,
+the first argument (<B>$1</B>) is the name of the command whose arguments are
+being completed,
+the second argument (<B>$2</B>) is the word being completed,
+and the third argument (<B>$3</B>) is the word preceding the word being
+completed on the current command line.
+No filtering of the generated completions against the word being completed
+is performed; the function or command has complete freedom in generating
+the matches.
+<P>
+
+Any function specified with <B>-F</B> is invoked first.
+The function may use any of the shell facilities, including the
+<B>compgen</B> builtin described below, to generate the matches.
+It must put the possible completions in the
+<FONT SIZE=-1><B>COMPREPLY</B>
+
+</FONT>
+array variable, one per array element.
+<P>
+
+Next, any command specified with the <B>-C</B> option is invoked
+in an environment equivalent to command substitution.
+It should print a list of completions, one per line, to the
+standard output.
+Backslash may be used to escape a newline, if necessary.
+<P>
+
+After all of the possible completions are generated, any filter
+specified with the <B>-X</B> option is applied to the list.
+The filter is a pattern as used for pathname expansion; a <B>&amp;</B>
+in the pattern is replaced with the text of the word being completed.
+A literal <B>&amp;</B> may be escaped with a backslash; the backslash
+is removed before attempting a match.
+Any completion that matches the pattern will be removed from the list.
+A leading <B>!</B> negates the pattern; in this case any completion
+not matching the pattern will be removed.
+If the
+<B>nocasematch</B>
+
+shell option is enabled, the match is performed without regard to the case
+of alphabetic characters.
+<P>
+
+Finally, any prefix and suffix specified with the <B>-P</B> and <B>-S</B>
+options are added to each member of the completion list, and the result is
+returned to the readline completion code as the list of possible
+completions.
+<P>
+
+If the previously-applied actions do not generate any matches, and the
+<B>-o dirnames</B> option was supplied to <B>complete</B> when the
+compspec was defined, directory name completion is attempted.
+<P>
+
+If the <B>-o plusdirs</B> option was supplied to <B>complete</B> when the
+compspec was defined, directory name completion is attempted and any
+matches are added to the results of the other actions.
+<P>
+
+By default, if a compspec is found, whatever it generates is returned
+to the completion code as the full set of possible completions.
+The default <B>bash</B> completions are not attempted, and the readline
+default of filename completion is disabled.
+If the <B>-o bashdefault</B> option was supplied to <B>complete</B> when
+the compspec was defined, the <B>bash</B> default completions are attempted
+if the compspec generates no matches.
+If the <B>-o default</B> option was supplied to <B>complete</B> when the
+compspec was defined, readline's default completion will be performed
+if the compspec (and, if attempted, the default <B>bash</B> completions)
+generate no matches.
+<P>
+
+When a compspec indicates that directory name completion is desired,
+the programmable completion functions force readline to append a slash
+to completed names which are symbolic links to directories, subject to
+the value of the <B>mark-directories</B> readline variable, regardless
+of the setting of the <B>mark-symlinked-directories</B> readline variable.
+<P>
+
+There is some support for dynamically modifying completions.  This is
+most useful when used in combination with a default completion specified
+with <B>complete -D</B>.
+It's possible for shell functions executed as completion
+handlers to indicate that completion should be retried by returning an
+exit status of 124.  If a shell function returns 124, and changes
+the compspec associated with the command on which completion is being
+attempted (supplied as the first argument when the function is executed),
+programmable completion restarts from the beginning, with an
+attempt to find a new compspec for that command.  This allows a set of
+completions to be built dynamically as completion is attempted, rather than
+being loaded all at once.
+<P>
+
+For instance, assuming that there is a library of compspecs, each kept in a
+file corresponding to the name of the command, the following default
+completion function would load completions dynamically:
+<P>
+
+<TT>_completion_loader()
+<BR>
+
+{
+<BR>
+
+<TT>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</TT>. &quot;/etc/bash_completion.d/$1.sh&quot; &gt;/dev/null 2&gt;&amp;1 &amp;&amp; return 124<BR>

+<H3>HISTORY</H3>
+
+When the
+<B>-o history</B>
+
+option to the
+<B>set</B>
+
+builtin is enabled, the shell provides access to the
+<I>command history</I>,
+the list of commands previously typed.
+The value of the
+<FONT SIZE=-1><B>HISTSIZE</B>
+
+</FONT>
+variable is used as the
+number of commands to save in a history list.
+The text of the last
+<FONT SIZE=-1><B>HISTSIZE</B>
+
+</FONT>
+commands (default 500) is saved.  The shell
+stores each command in the history list prior to parameter and
+variable expansion (see
+<FONT SIZE=-1><B>EXPANSION</B>
+
+</FONT>
+above) but after history expansion is performed, subject to the
+values of the shell variables
+<FONT SIZE=-1><B>HISTIGNORE</B>
+
+</FONT>
+and
+<FONT SIZE=-1><B>HISTCONTROL</B>.
+
+</FONT>
+<P>
+
+On startup, the history is initialized from the file named by
+the variable
+<FONT SIZE=-1><B>HISTFILE</B>
+
+</FONT>
+(default <A HREF="file:~/.bash_history"><I>~/.bash_history</I></A>).
+The file named by the value of
+<FONT SIZE=-1><B>HISTFILE</B>
+
+</FONT>
+is truncated, if necessary, to contain no more than
+the number of lines specified by the value of
+<FONT SIZE=-1><B>HISTFILESIZE</B>.
+
+</FONT>
+If <B>HISTFILESIZE</B> is unset, or set to null, a non-numeric value,
+or a numeric value less than zero, the history file is not truncated.
+When the history file is read,
+lines beginning with the history comment character followed immediately
+by a digit are interpreted as timestamps for the following history line.
+These timestamps are optionally displayed depending on the value of the
+<FONT SIZE=-1><B>HISTTIMEFORMAT</B>
+
+</FONT>
+variable.
+When a shell with history enabled exits, the last
+<FONT SIZE=-1><B>$HISTSIZE</B>
+
+</FONT>
+lines are copied from the history list to
+<FONT SIZE=-1><B>$HISTFILE</B>.
+
+</FONT>
+If the
+<B>histappend</B>
+
+shell option is enabled
+(see the description of
+<B>shopt</B>
+
+under
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below), the lines are appended to the history file,
+otherwise the history file is overwritten.
+If
+<FONT SIZE=-1><B>HISTFILE</B>
+
+</FONT>
+is unset, or if the history file is unwritable, the history is
+not saved.
+If the
+<FONT SIZE=-1><B>HISTTIMEFORMAT</B>
+
+</FONT>
+variable is set, time stamps are written to the history file, marked
+with the history comment character, so
+they may be preserved across shell sessions.
+This uses the history comment character to distinguish timestamps from
+other history lines.
+After saving the history, the history file is truncated
+to contain no more than
+<FONT SIZE=-1><B>HISTFILESIZE</B>
+
+</FONT>
+lines.  If
+<FONT SIZE=-1><B>HISTFILESIZE</B>
+
+</FONT>
+is unset, or set to null, a non-numeric value,
+or a numeric value less than zero, the history file is not truncated.
+<P>
+
+The builtin command
+<B>fc</B>
+
+(see
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below) may be used to list or edit and re-execute a portion of
+the history list.
+The
+<B>history</B>
+
+builtin may be used to display or modify the history list and
+manipulate the history file.
+When using command-line editing, search commands
+are available in each editing mode that provide access to the
+history list.

+
+The shell allows control over which commands are saved on the history

+<FONT SIZE=-1><B>HISTCONTROL</B>
+
+</FONT>
+and
+<FONT SIZE=-1><B>HISTIGNORE</B>
+
+</FONT>
+variables may be set to cause the shell to save only a subset of the
+commands entered.
+The
+<B>cmdhist</B>
+
+shell option, if enabled, causes the shell to attempt to save each
+line of a multi-line command in the same history entry, adding
+semicolons where necessary to preserve syntactic correctness.
+The
+<B>lithist</B>
+
+shell option causes the shell to save the command with embedded newlines
+instead of semicolons.  See the description of the
+<B>shopt</B>

+<A NAME="lbCX">&nbsp;</A>
+<H3>HISTORY EXPANSION</H3>
+
+The shell supports a history expansion feature that
+is similar to the history expansion in
+<B>csh</B>.
+
+This section describes what syntax features are available.  This
+feature is enabled by default for interactive shells, and can be
+disabled using the
+<B>+H</B>
+
+option to the
+<B>set</B>
+
+builtin command (see
+<FONT SIZE=-1><B>SHELL BUILTIN COMMANDS</B>
+
+</FONT>
+below).  Non-interactive shells do not perform history expansion
+by default.
+<P>
+
+History expansions introduce words from the history list into
+the input stream, making it easy to repeat commands, insert the
+arguments to a previous command into the current input line, or
+fix errors in previous commands quickly.
+<P>
+
+History expansion is performed immediately after a complete line
+is read, before the shell breaks it into words, and is performed
+on each line individually without taking quoting on previous lines into
+account.
+It takes place in two parts.
+The first is to determine which line from the history list
+to use during substitution.
+The second is to select portions of that line for inclusion into
+the current one.
+The line selected from the history is the <I>event</I>,
+and the portions of that line that are acted upon are <I>words</I>.
+Various <I>modifiers</I> are available to manipulate the selected words.
+The line is broken into words in the same fashion as when reading input,
+so that several <I>metacharacter</I>-separated words surrounded by
+quotes are considered one word.
+History expansions are introduced by the appearance of the
+history expansion character, which is <B>!</B> by default.
+Only backslash (<B>\</B>) and single quotes can quote
+the history expansion character, but the history expansion character is
+also treated as quoted if it immediately precedes the closing double quote
+in a double-quoted string.
+<P>
+
+Several characters inhibit history expansion if found immediately
+following the history expansion character, even if it is unquoted:
+space, tab, newline, carriage return, and <B>=</B>.
+If the <B>extglob</B> shell option is enabled, <B>(</B> will also
+inhibit expansion.
+<P>
+
+Several shell options settable with the
+<B>shopt</B>
+
+builtin may be used to tailor the behavior of history expansion.
+If the
+<B>histverify</B>
+
+shell option is enabled (see the description of the
+<B>shopt</B>
+
+builtin below), and
+<B>readline</B>
+
+is being used, history substitutions are not immediately passed to
+the shell parser.
+Instead, the expanded line is reloaded into the
+<B>readline</B>
+
+editing buffer for further modification.
+If
+<B>readline</B>
+
+is being used, and the
+<B>histreedit</B>
+
+shell option is enabled, a failed history substitution will be reloaded
+into the
+<B>readline</B>
+
+editing buffer for correction.
+The
+<B>-p</B>
+
+option to the
+<B>history</B>
+
+builtin command may be used to see what a history expansion will
+do before using it.
+The
+<B>-s</B>
+
+option to the
+<B>history</B>
+
+builtin may be used to add commands to the end of the history list
+without actually executing them, so that they are available for
+subsequent recall.
+<P>
+
+The shell allows control of the various characters used by the
+history expansion mechanism (see the description of
+<B>histchars</B>
+
+above under
+<B>Shell Variables</B>).
+
+The shell uses
+the history comment character to mark history timestamps when
+writing the history file.

+Execute the specified shell builtin, passing it

+This is useful when defining a
+function whose name is the same as a shell builtin,
+retaining the functionality of the builtin within the function.

+<DT><B>caller</B> [<I>expr</I>]<DD>
+Returns the context of any active subroutine call (a shell function or

+Without <I>expr</I>, <B>caller</B> displays the line number and source
+filename of the current subroutine call.
+If a non-negative integer is supplied as <I>expr</I>, <B>caller</B>
+displays the line number, subroutine name, and source file corresponding
+to that position in the current execution call stack.  This extra
+information may be used, for example, to print a stack trace.  The
+current frame is frame 0.
+The return value is 0 unless the shell is not executing a subroutine

+call stack.
+<DT><B>cd</B> [<B>-L</B>|[<B>-P</B> [<B>-e</B>]] [-@]] [<I>dir</I>]<DD>
+Change the current directory to <I>dir</I>.
+if <I>dir</I> is not supplied, the value of the
+<FONT SIZE=-1><B>HOME</B>
+
+</FONT>
+shell variable is the default.
+The variable
+<FONT SIZE=-1><B>CDPATH</B>
+
+</FONT>
+defines the search path for the directory containing
+<I>dir</I>:
+
+each directory name in
+<FONT SIZE=-1><B>CDPATH</B>
+
+</FONT>
+is searched for <I>dir</I>.
+Alternative directory names in
+<FONT SIZE=-1><B>CDPATH</B>
+
+</FONT>
+are separated by a colon (:).  A null directory name in
+<FONT SIZE=-1><B>CDPATH</B>
+
+</FONT>
+is the same as the current directory, i.e., ``<B>.</B>''.  If
+<I>dir</I>
+
+begins with a slash (/),
+then
+<FONT SIZE=-1><B>CDPATH</B>
+
+</FONT>
+is not used.  The
+<B>-P</B>
+
+option causes <B>cd</B> to use the physical directory structure
+by resolving symbolic links while traversing <I>dir</I> and
+before processing instances of <I>..</I> in <I>dir</I> (see also the
+<B>-P</B>
+
+option to the
+<B>set</B>
+
+builtin command); the
+<B>-L</B>
+
+option forces symbolic links to be followed by resolving the link
+after processing instances of <I>..</I> in <I>dir</I>.
+If <I>..</I> appears in <I>dir</I>, it is processed by removing the
+immediately previous pathname component from <I>dir</I>, back to a slash
+or the beginning of <I>dir</I>.
+If the
+<B>-e</B>
+
+option is supplied with
+<B>-P</B>,
+
+and the current working directory cannot be successfully determined
+after a successful directory change, <B>cd</B> will return an unsuccessful
+status.
+On systems that support it, the <B>-@</B> option presents the extended
+attributes associated with a file as a directory.
+An argument of
+<B>-</B>
+
+is converted to
+<FONT SIZE=-1><B>$OLDPWD</B>
+
+</FONT>
+before the directory change is attempted.
+If a non-empty directory name from
+<FONT SIZE=-1><B>CDPATH</B>
+
+</FONT>
+is used, or if
+<B>-</B> is the first argument, and the directory change is
+successful, the absolute pathname of the new working directory is
+written to the standard output.
+If the directory change is successful, <B>cd</B> sets the value of the
+<B>PWD</B> environment variable to the new directory name, and sets the
+<B>OLDPWD</B> environment variable to the value of the current working
+directory before the change.
+The return value is true if the directory was successfully changed;
+false otherwise.
+<DT><B>command</B> [<B>-pVv</B>] <I>command</I> [<I>arg</I> ...]<DD>
+Run

+
+suppressing the normal shell function lookup.
+Only builtin commands or commands found in the
+<FONT SIZE=-1><B>PATH</B>
+
+</FONT>
+are executed.  If the
+<B>-p</B>
+
+option is given, the search for
+<I>command</I>
+
+is performed using a default value for
+<FONT SIZE=-1><B>PATH</B>
+
+</FONT>
+that is guaranteed to find all of the standard utilities.
+If either the
+<B>-V</B>
+
+or
+<B>-v</B>
+
+option is supplied, a description of
+<I>command</I>
+
+is printed.  The
+<B>-v</B>
+
+option causes a single word indicating the command or filename
+used to invoke
+<I>command</I>
+
+to be displayed; the
+<B>-V</B>
+
+option produces a more verbose description.
+If the
+<B>-V</B>
+
+or
+<B>-v</B>
+
+option is supplied, the exit status is 0 if
+<I>command</I>
+
+was found, and 1 if not.  If neither option is supplied and
+an error occurred or
+<I>command</I>
+
+cannot be found, the exit status is 127.  Otherwise, the exit status of the

+The <B>-I</B> option indicates that other supplied options and actions should
+apply to completion on the initial non-assignment word on the line, or after
+a command delimiter such as <B>;</B> or <B>|</B>, which is usually command
+name completion.
+If multiple options are supplied, the <B>-D</B> option takes precedence

+Enable and disable builtin shell commands.
+Disabling a builtin allows a disk command which has the same name
+as a shell builtin to be executed without specifying a full pathname,
+even though the shell normally searches for builtins before disk commands.
+If <B>-n</B> is used, each <I>name</I>
+is disabled; otherwise,
+<I>names</I> are enabled.  For example, to use the
+<B>test</B>
+
+binary found via the
+<FONT SIZE=-1><B>PATH</B>
+
+</FONT>
+instead of the shell builtin version, run
+<TT>enable -n test</TT>.
+
+The
+<B>-f</B>
+
+option means to load the new builtin command
+<I>name</I>
+
+from shared object
+<I>filename</I>,
+
+on systems that support dynamic loading.
+Bash will use the value of the <B>BASH_LOADABLES_PATH</B> variable as a
+colon-separated list of directories in which to search for <I>filename</I>.
+The default is system-dependent.
+The
+<B>-d</B>
+
+option will delete a builtin previously loaded with
+<B>-f</B>.
+
+If no <I>name</I> arguments are given, or if the
+<B>-p</B>
+
+option is supplied, a list of shell builtins is printed.
+With no other option arguments, the list consists of all enabled
+shell builtins.
+If <B>-n</B> is supplied, only disabled builtins are printed.
+If <B>-a</B> is supplied, the list printed includes all builtins, with an
+indication of whether or not each is enabled.
+If <B>-s</B> is supplied, the output is restricted to the POSIX
+<I>special</I> builtins.
+If no options are supplied and a <I>name</I> is not a shell builtin,
+<B>enable</B> will attempt to load <I>name</I> from a shared object named
+<I>name</I>, as if the command were
+<TT>enable -f</TT> <I>name name</I> .
+
+The return value is 0 unless a

+<DT><B>eval</B> [<I>arg</I> ...]<DD>
+The <I>arg</I>s are read and concatenated together into a single

+the shell places a dash at the beginning of the zeroth argument passed to
+<I>command</I>.
+
+This is what
+<I>login</I>(1)
+
+does.  The
+<B>-c</B>
+

+
+to be executed with an empty environment.  If

+
+is supplied, the shell passes

+If
+<I>command</I>
+
+cannot be executed for some reason, a non-interactive shell exits,
+unless the
+<B>execfail</B>
+

+is enabled.  In that case, it returns failure.
+An interactive shell returns failure if the file cannot be executed.
+A subshell exits unconditionally if <B>exec</B> fails.
+If

+
+The first form selects a range of commands from

+
+to
+<I>last</I>
+
+from the history list and displays or edits and re-executes them.
+<I>First</I>
+
+and
+<I>last</I>
+
+may be specified as a string (to locate the last command beginning
+with that string) or as a number (an index into the history list,
+where a negative number is used as an offset from the current
+command number).
+When listing, a <I>first</I> or <I>last</I> of
+0 is equivalent to -1 and -0 is equivalent to the current
+command (usually the <B>fc</B> command); otherwise 0 is equivalent to -1
+and -0 is invalid.
+If
+<I>last</I>
+
+is not specified, it is set to
+the current command for listing (so that
+
+<TT>fc -l -10</TT>
+prints the last 10 commands) and to
+<I>first</I>
+
+otherwise.
+If
+<I>first</I>
+
+is not specified, it is set to the previous
+command for editing and -16 for listing.
+<P>
+The
+<B>-n</B>
+
+option suppresses
+the command numbers when listing.  The
+<B>-r</B>
+
+option reverses the order of
+the commands.  If the
+<B>-l</B>
+
+option is given,
+the commands are listed on
+standard output.  Otherwise, the editor given by
+<I>ename</I>
+
+is invoked
+on a file containing those commands.  If
+<I>ename</I>
+
+is not given, the
+value of the
+<FONT SIZE=-1><B>FCEDIT</B>
+
+</FONT>
+variable is used, and
+the value of
+<FONT SIZE=-1><B>EDITOR</B>
+
+</FONT>
+if
+<FONT SIZE=-1><B>FCEDIT</B>
+
+</FONT>
+is not set.  If neither variable is set,
+
+<I>vi</I>
+
+is used.  When editing is complete, the edited commands are
+echoed and executed.
+<P>
+In the second form, <I>command</I> is re-executed after each instance
+of <I>pat</I> is replaced by <I>rep</I>.
+<I>Command</I> is interpreted the same as <I>first</I> above.
+A useful alias to use with this is
+
+<TT>r='fc -s'</TT>,
+so that typing
+
+<TT>r cc</TT>
+runs the last command beginning with
+
+<TT>cc</TT>
+and typing
+
+<TT>r</TT>
+re-executes the last command.

+If the first form is used, the return value is 0 unless an invalid
+option is encountered or
+<I>first</I>
+
+or
+<I>last</I>
+
+specify history lines out of range.
+If the
+<B>-e</B>
+
+option is supplied, the return value is the value of the last
+command executed or failure if an error occurs with the temporary
+file of commands.  If the second form is used, the return status
+is that of the command re-executed, unless
+<I>cmd</I>
+
+does not specify a valid history line, in which case
+<B>fc</B>
+
+returns failure.

+
+in the foreground, and make it the current job.
+If
+<I>jobspec</I>
+
+is not present, the shell's notion of the <I>current job</I> is used.
+The return value is that of the command placed into the foreground,
+or failure if run when job control is disabled or, when run with
+job control enabled, if
+<I>jobspec</I>
+
+does not specify a valid job or

+The <I>format</I> is a character string which contains three types of objects:

+Arguments to non-string format specifiers are treated as C constants,

+<H3>SHELL COMPATIBILITY MODE</H3>
+
+Bash-4.0 introduced the concept of a <I>shell compatibility level</I>,
+specified as a set of options to the shopt builtin (
+<B>compat31</B>,
+
+<B>compat32</B>,
+
+<B>compat40</B>,
+
+<B>compat41</B>,
+
+and so on).
+There is only one current
+compatibility level -- each option is mutually exclusive.
+The compatibility level is intended to allow users to select behavior
+from previous versions that is incompatible with newer versions
+while they migrate scripts to use current features and
+behavior. It's intended to be a temporary solution.
+<P>
+
+This section does not mention behavior that is standard for a particular
+version (e.g., setting <B>compat32</B> means that quoting the rhs of the regexp
+matching operator quotes special regexp characters in the word, which is
+default behavior in bash-3.2 and subsequent versions). 
+<P>
+
+If a user enables, say, <B>compat32</B>, it may affect the behavior of other
+compatibility levels up to and including the current compatibility level.
+The idea is that each compatibility level controls behavior that changed
+in that version of <B>bash</B>,
+but that behavior may have been present in earlier versions.
+For instance, the change to use locale-based comparisons with the <B>[[</B>
+command came in bash-4.1, and earlier versions used ASCII-based comparisons,
+so enabling <B>compat32</B> will enable ASCII-based comparisons as well.
+That granularity may not be sufficient for
+all uses, and as a result users should employ compatibility levels carefully.
+Read the documentation for a particular feature to find out the
+current behavior.
+<P>
+
+Bash-4.3 introduced a new shell variable:
+<FONT SIZE=-1><B>BASH_COMPAT</B>.
+
+</FONT>
+The value assigned
+to this variable (a decimal version number like 4.2, or an integer
+corresponding to the <B>compat</B><I>NN</I> option, like 42) determines the
+compatibility level.
+<P>
+
+Starting with bash-4.4, Bash has begun deprecating older compatibility
+levels.
+Eventually, the options will be removed in favor of
+<FONT SIZE=-1><B>BASH_COMPAT</B>.
+
+</FONT>
+<P>
+
+Bash-5.0 is the final version for which there will be an individual shopt
+option for the previous version. Users should use
+<FONT SIZE=-1><B>BASH_COMPAT</B>
+
+</FONT>
+on bash-5.0 and later versions.
+<P>
+
+The following table describes the behavior changes controlled by each
+compatibility level setting.
+The <B>compat</B><I>NN</I> tag is used as shorthand for setting the
+compatibility level
+to <I>NN</I> using one of the following mechanisms.
+For versions prior to bash-5.0, the compatibility level may be set using
+the corresponding <B>compat</B><I>NN</I> shopt option.
+For bash-4.3 and later versions, the
+<FONT SIZE=-1><B>BASH_COMPAT</B>
+
+</FONT>
+variable is preferred,
+and it is required for bash-5.1 and later versions.

+
+1.1 What is Bash?
+=================
+
+Bash is the shell, or command language interpreter, for the GNU
+operating system.  The name is an acronym for the 'Bourne-Again SHell',
+a pun on Stephen Bourne, the author of the direct ancestor of the
+current Unix shell 'sh', which appeared in the Seventh Edition Bell Labs
+Research version of Unix.
+
+   Bash is largely compatible with 'sh' and incorporates useful features
+from the Korn shell 'ksh' and the C shell 'csh'.  It is intended to be a
+conformant implementation of the IEEE POSIX Shell and Tools portion of
+the IEEE POSIX specification (IEEE Standard 1003.1).  It offers
+functional improvements over 'sh' for both interactive and programming
+use.
+
+   While the GNU operating system provides other shells, including a
+version of 'csh', Bash is the default shell.  Like other GNU software,
+Bash is quite portable.  It currently runs on nearly every version of
+Unix and a few other operating systems - independently-supported ports
+exist for MS-DOS, OS/2, and Windows platforms.
+
+
+File: bash.info,  Node: What is a shell?,  Prev: What is Bash?,  Up: Introduction
+
+1.2 What is a shell?
+====================
+
+At its base, a shell is simply a macro processor that executes commands.
+The term macro processor means functionality where text and symbols are
+expanded to create larger expressions.
+
+   A Unix shell is both a command interpreter and a programming
+language.  As a command interpreter, the shell provides the user
+interface to the rich set of GNU utilities.  The programming language
+features allow these utilities to be combined.  Files containing
+commands can be created, and become commands themselves.  These new
+commands have the same status as system commands in directories such as
+'/bin', allowing users or groups to establish custom environments to
+automate their common tasks.
+
+   Shells may be used interactively or non-interactively.  In
+interactive mode, they accept input typed from the keyboard.  When
+executing non-interactively, shells execute commands read from a file.
+
+   A shell allows execution of GNU commands, both synchronously and
+asynchronously.  The shell waits for synchronous commands to complete
+before accepting more input; asynchronous commands continue to execute
+in parallel with the shell while it reads and executes additional
+commands.  The "redirection" constructs permit fine-grained control of
+the input and output of those commands.  Moreover, the shell allows
+control over the contents of commands' environments.
+
+   Shells also provide a small set of built-in commands ("builtins")
+implementing functionality impossible or inconvenient to obtain via
+separate utilities.  For example, 'cd', 'break', 'continue', and 'exec'
+cannot be implemented outside of the shell because they directly
+manipulate the shell itself.  The 'history', 'getopts', 'kill', or 'pwd'
+builtins, among others, could be implemented in separate utilities, but
+they are more convenient to use as builtin commands.  All of the shell
+builtins are described in subsequent sections.
+
+   While executing commands is essential, most of the power (and
+complexity) of shells is due to their embedded programming languages.
+Like any high-level language, the shell provides variables, flow control
+constructs, quoting, and functions.
+
+   Shells offer features geared specifically for interactive use rather
+than to augment the programming language.  These interactive features
+include job control, command line editing, command history and aliases.
+Each of these features is described in this manual.

+
+2 Definitions
+*************
+
+These definitions are used throughout the remainder of this manual.
+
+'POSIX'
+     A family of open system standards based on Unix.  Bash is primarily
+     concerned with the Shell and Utilities portion of the POSIX 1003.1
+     standard.
+
+'blank'
+     A space or tab character.
+
+'builtin'
+     A command that is implemented internally by the shell itself,
+     rather than by an executable program somewhere in the file system.
+
+'control operator'
+     A 'token' that performs a control function.  It is a 'newline' or
+     one of the following: '||', '&&', '&', ';', ';;', ';&', ';;&', '|',
+     '|&', '(', or ')'.
+
+'exit status'
+     The value returned by a command to its caller.  The value is
+     restricted to eight bits, so the maximum value is 255.
+
+'field'
+     A unit of text that is the result of one of the shell expansions.
+     After expansion, when executing a command, the resulting fields are
+     used as the command name and arguments.
+
+'filename'
+     A string of characters used to identify a file.
+
+'job'
+     A set of processes comprising a pipeline, and any processes
+     descended from it, that are all in the same process group.
+
+'job control'
+     A mechanism by which users can selectively stop (suspend) and
+     restart (resume) execution of processes.
+
+'metacharacter'
+     A character that, when unquoted, separates words.  A metacharacter
+     is a 'space', 'tab', 'newline', or one of the following characters:
+     '|', '&', ';', '(', ')', '<', or '>'.
+
+'name'
+     A 'word' consisting solely of letters, numbers, and underscores,
+     and beginning with a letter or underscore.  'Name's are used as
+     shell variable and function names.  Also referred to as an
+     'identifier'.
+
+'operator'
+     A 'control operator' or a 'redirection operator'.  *Note
+     Redirections::, for a list of redirection operators.  Operators
+     contain at least one unquoted 'metacharacter'.
+
+'process group'
+     A collection of related processes each having the same process
+     group ID.
+
+'process group ID'
+     A unique identifier that represents a 'process group' during its
+     lifetime.
+
+'reserved word'
+     A 'word' that has a special meaning to the shell.  Most reserved
+     words introduce shell flow control constructs, such as 'for' and
+     'while'.
+
+'return status'
+     A synonym for 'exit status'.
+
+'signal'
+     A mechanism by which a process may be notified by the kernel of an
+     event occurring in the system.
+
+'special builtin'
+     A shell builtin command that has been classified as special by the
+     POSIX standard.
+
+'token'
+     A sequence of characters considered a single unit by the shell.  It
+     is either a 'word' or an 'operator'.
+
+'word'
+     A sequence of characters treated as a unit by the shell.  Words may
+     not include unquoted 'metacharacters'.

+
+3 Basic Shell Features
+**********************
+
+Bash is an acronym for 'Bourne-Again SHell'.  The Bourne shell is the
+traditional Unix shell originally written by Stephen Bourne.  All of the
+Bourne shell builtin commands are available in Bash, The rules for
+evaluation and quoting are taken from the POSIX specification for the
+'standard' Unix shell.
+
+   This chapter briefly summarizes the shell's 'building blocks':
+commands, control structures, shell functions, shell parameters, shell
+expansions, redirections, which are a way to direct input and output
+from and to named files, and how the shell executes commands.

+================
+
+* Menu:
+
+* Shell Operation::	The basic operation of the shell.
+* Quoting::		How to remove the special meaning from characters.
+* Comments::		How to specify comments.
+
+When the shell reads input, it proceeds through a sequence of
+operations.  If the input indicates the beginning of a comment, the
+shell ignores the comment symbol ('#'), and the rest of that line.
+
+   Otherwise, roughly speaking, the shell reads its input and divides
+the input into words and operators, employing the quoting rules to
+select which meanings to assign various words and characters.
+
+   The shell then parses these tokens into commands and other
+constructs, removes the special meaning of certain words or characters,
+expands others, redirects input and output as needed, executes the
+specified command, waits for the command's exit status, and makes that
+exit status available for further inspection or processing.
+

+
+3.1.1 Shell Operation
+---------------------
+
+The following is a brief description of the shell's operation when it
+reads and executes a command.  Basically, the shell does the following:
+
+  1. Reads its input from a file (*note Shell Scripts::), from a string
+     supplied as an argument to the '-c' invocation option (*note
+     Invoking Bash::), or from the user's terminal.
+
+  2. Breaks the input into words and operators, obeying the quoting
+     rules described in *note Quoting::.  These tokens are separated by
+     'metacharacters'.  Alias expansion is performed by this step (*note
+     Aliases::).
+
+  3. Parses the tokens into simple and compound commands (*note Shell
+     Commands::).
+
+  4. Performs the various shell expansions (*note Shell Expansions::),
+     breaking the expanded tokens into lists of filenames (*note
+     Filename Expansion::) and commands and arguments.
+
+  5. Performs any necessary redirections (*note Redirections::) and
+     removes the redirection operators and their operands from the
+     argument list.
+
+  6. Executes the command (*note Executing Commands::).
+
+  7. Optionally waits for the command to complete and collects its exit
+     status (*note Exit Status::).

+
+3.1.2 Quoting
+-------------
+
+* Menu:
+
+* Escape Character::	How to remove the special meaning from a single
+			character.
+* Single Quotes::	How to inhibit all interpretation of a sequence
+			of characters.
+* Double Quotes::	How to suppress most of the interpretation of a
+			sequence of characters.
+* ANSI-C Quoting::	How to expand ANSI-C sequences in quoted strings.
+* Locale Translation::	How to translate strings into different languages.
+
+Quoting is used to remove the special meaning of certain characters or
+words to the shell.  Quoting can be used to disable special treatment
+for special characters, to prevent reserved words from being recognized
+as such, and to prevent parameter expansion.
+
+   Each of the shell metacharacters (*note Definitions::) has special
+meaning to the shell and must be quoted if it is to represent itself.
+When the command history expansion facilities are being used (*note
+History Interaction::), the "history expansion" character, usually '!',
+must be quoted to prevent history expansion.  *Note Bash History
+Facilities::, for more details concerning history expansion.
+
+   There are three quoting mechanisms: the "escape character", single
+quotes, and double quotes.
+
+
+File: bash.info,  Node: Escape Character,  Next: Single Quotes,  Up: Quoting
+
+3.1.2.1 Escape Character
+........................
+
+A non-quoted backslash '\' is the Bash escape character.  It preserves
+the literal value of the next character that follows, with the exception
+of 'newline'.  If a '\newline' pair appears, and the backslash itself is
+not quoted, the '\newline' is treated as a line continuation (that is,
+it is removed from the input stream and effectively ignored).
+
+
+File: bash.info,  Node: Single Quotes,  Next: Double Quotes,  Prev: Escape Character,  Up: Quoting
+
+3.1.2.2 Single Quotes
+.....................
+
+Enclosing characters in single quotes (''') preserves the literal value
+of each character within the quotes.  A single quote may not occur
+between single quotes, even when preceded by a backslash.
+
+
+File: bash.info,  Node: Double Quotes,  Next: ANSI-C Quoting,  Prev: Single Quotes,  Up: Quoting
+
+3.1.2.3 Double Quotes
+.....................
+
+Enclosing characters in double quotes ('"') preserves the literal value
+of all characters within the quotes, with the exception of '$', '`',
+'\', and, when history expansion is enabled, '!'.  When the shell is in
+POSIX mode (*note Bash POSIX Mode::), the '!' has no special meaning
+within double quotes, even when history expansion is enabled.  The
+characters '$' and '`' retain their special meaning within double quotes
+(*note Shell Expansions::).  The backslash retains its special meaning
+only when followed by one of the following characters: '$', '`', '"',
+'\', or 'newline'.  Within double quotes, backslashes that are followed
+by one of these characters are removed.  Backslashes preceding
+characters without a special meaning are left unmodified.  A double
+quote may be quoted within double quotes by preceding it with a
+backslash.  If enabled, history expansion will be performed unless an
+'!' appearing in double quotes is escaped using a backslash.  The
+backslash preceding the '!' is not removed.
+
+   The special parameters '*' and '@' have special meaning when in
+double quotes (*note Shell Parameter Expansion::).
+
+
+File: bash.info,  Node: ANSI-C Quoting,  Next: Locale Translation,  Prev: Double Quotes,  Up: Quoting
+
+3.1.2.4 ANSI-C Quoting
+......................
+
+Character sequences of the form $'STRING' are treated as a special kind
+of single quotes.  The sequence expands to STRING, with
+backslash-escaped characters in STRING replaced as specified by the ANSI
+C standard.  Backslash escape sequences, if present, are decoded as
+follows:
+
+'\a'
+     alert (bell)
+'\b'
+     backspace
+'\e'
+'\E'
+     an escape character (not ANSI C)
+'\f'
+     form feed
+'\n'
+     newline
+'\r'
+     carriage return
+'\t'
+     horizontal tab
+'\v'
+     vertical tab
+'\\'
+     backslash
+'\''
+     single quote
+'\"'
+     double quote
+'\?'
+     question mark
+'\NNN'
+     the eight-bit character whose value is the octal value NNN (one to
+     three octal digits)
+'\xHH'
+     the eight-bit character whose value is the hexadecimal value HH
+     (one or two hex digits)
+'\uHHHH'
+     the Unicode (ISO/IEC 10646) character whose value is the
+     hexadecimal value HHHH (one to four hex digits)
+'\UHHHHHHHH'
+     the Unicode (ISO/IEC 10646) character whose value is the
+     hexadecimal value HHHHHHHH (one to eight hex digits)
+'\cX'
+     a control-X character
+
+The expanded result is single-quoted, as if the dollar sign had not been
+present.

+
+3.1.2.5 Locale-Specific Translation
+...................................
+
+* Menu:
+
+* Creating Internationalized Scripts::	How to use translations and different
+					languages in your scripts.
+
+Prefixing a double-quoted string with a dollar sign ('$'), such as
+$"hello, world", will cause the string to be translated according to the
+current locale.  The 'gettext' infrastructure performs the lookup and
+translation, using the 'LC_MESSAGES', 'TEXTDOMAINDIR', and 'TEXTDOMAIN'
+shell variables, as explained below.  See the gettext documentation for
+additional details not covered here.  If the current locale is 'C' or
+'POSIX', if there are no translations available, of if the string is not
+translated, the dollar sign is ignored.  Since this is a form of double
+quoting, the string remains double-quoted by default, whether or not it
+is translated and replaced.  If the 'noexpand_translation' option is
+enabled using the 'shopt' builtin (*note The Shopt Builtin::),
+translated strings are single-quoted instead of double-quoted.
+
+   The rest of this section is a brief overview of how you use gettext
+to create translations for strings in a shell script named SCRIPTNAME.
+There are more details in the gettext documentation.

+using $"...", you create a gettext "template" file using the command
+
+     bash --dump-po-strings SCRIPTNAME > DOMAIN.pot
+
+The DOMAIN is your "message domain".  It's just an arbitrary string
+that's used to identify the files gettext needs, like a package or
+script name.  It needs to be unique among all the message domains on
+systems where you install the translations, so gettext knows which
+translations correspond to your script.  You'll use the template file to
+create translations for each target language.  The template file
+conventionally has the suffix '.pot'.
+
+   You copy this template file to a separate file for each target
+language you want to support (called "PO" files, which use the suffix
+'.po').  PO files use various naming conventions, but when you are
+working to translate a template file into a particular language, you
+first copy the template file to a file whose name is the language you
+want to target, with the '.po' suffix.  For instance, the Spanish
+translations of your strings would be in a file named 'es.po', and to
+get started using a message domain named "example," you would run
+
+     cp example.pot es.po
+
+Ultimately, PO files are often named DOMAIN.po and installed in
+directories that contain multiple translation files for a particular
+language.
+
+   Whichever naming convention you choose, you will need to translate
+the strings in the PO files into the appropriate languages.  This has to
+be done manually.
+
+   When you have the translations and PO files complete, you'll use the
+gettext tools to produce what are called "MO" files, which are compiled
+versions of the PO files the gettext tools use to look up translations
+efficiently.  MO files are also called "message catalog" files.  You use
+the 'msgfmt' program to do this.  For instance, if you had a file with
+Spanish translations, you could run
+
+     msgfmt -o es.mo es.po
+
+to produce the corresponding MO file.
+
+   Once you have the MO files, you decide where to install them and use
+the 'TEXTDOMAINDIR' shell variable to tell the gettext tools where they
+are.  Make sure to use the same message domain to name the MO files as
+you did for the PO files when you install them.
+
+   Your users will use the 'LANG' or 'LC_MESSAGES' shell variables to
+select the desired language.
+
+   You set the 'TEXTDOMAIN' variable to the script's message domain.  As
+above, you use the message domain to name your translation files.
+
+   You, or possibly your users, set the 'TEXTDOMAINDIR' variable to the
+name of a directory where the message catalog files are stored.  If you
+install the message files into the system's standard message catalog
+directory, you don't need to worry about this variable.
+
+   The directory where the message catalog files are stored varies
+between systems.  Some use the message catalog selected by the
+'LC_MESSAGES' shell variable.  Others create the name of the message
+catalog from the value of the 'TEXTDOMAIN' shell variable, possibly
+adding the '.mo' suffix.  If you use the 'TEXTDOMAIN' variable, you may
+need to set the 'TEXTDOMAINDIR' variable to the location of the message
+catalog files, as above.  It's common to use both variables in this
+fashion: '$TEXTDOMAINDIR'/'$LC_MESSAGES'/LC_MESSAGES/'$TEXTDOMAIN'.mo.
+
+   If you used that last convention, and you wanted to store the message
+catalog files with Spanish (es) and Esperanto (eo) translations into a
+local directory you use for custom translation files, you could run
+
+     TEXTDOMAIN=example
+     TEXTDOMAINDIR=/usr/local/share/locale
+
+     cp es.mo ${TEXTDOMAINDIR}/es/LC_MESSAGES/${TEXTDOMAIN}.mo
+     cp eo.mo ${TEXTDOMAINDIR}/eo/LC_MESSAGES/${TEXTDOMAIN}.mo
+
+   When all of this is done, and the message catalog files containing
+the compiled translations are installed in the correct location, your
+users will be able to see translated strings in any of the supported
+languages by setting the 'LANG' or 'LC_MESSAGES' environment variables
+before running your script.

+3.2 Shell Commands
+==================
+
+A simple shell command such as 'echo a b c' consists of the command
+itself followed by arguments, separated by spaces.
+
+   More complex shell commands are composed of simple commands arranged
+together in a variety of ways: in a pipeline in which the output of one
+command becomes the input of a second, in a loop or conditional
+construct, or in some other grouping.

+
+3.2.1 Reserved Words
+--------------------
+
+Reserved words are words that have special meaning to the shell.  They
+are used to begin and end the shell's compound commands.
+
+   The following words are recognized as reserved when unquoted and the
+first word of a command (see below for exceptions):
+
+'if'    'then'  'elif'  'else'  'fi'      'time'
+'for'   'in'    'until' 'while' 'do'      'done'
+'case'  'esac'  'coproc''select''function'
+'{'     '}'     '[['    ']]'    '!'
+
+'in' is recognized as a reserved word if it is the third word of a
+'case' or 'select' command.  'in' and 'do' are recognized as reserved
+words if they are the third word in a 'for' command.
+
+
+File: bash.info,  Node: Simple Commands,  Next: Pipelines,  Prev: Reserved Words,  Up: Shell Commands
+
+3.2.2 Simple Commands
+---------------------
+
+A simple command is the kind of command encountered most often.  It's
+just a sequence of words separated by 'blank's, terminated by one of the
+shell's control operators (*note Definitions::).  The first word
+generally specifies a command to be executed, with the rest of the words
+being that command's arguments.
+
+   The return status (*note Exit Status::) of a simple command is its
+exit status as provided by the POSIX 1003.1 'waitpid' function, or 128+N
+if the command was terminated by signal N.
+
+
+File: bash.info,  Node: Pipelines,  Next: Lists,  Prev: Simple Commands,  Up: Shell Commands
+
+3.2.3 Pipelines
+---------------
+
+A 'pipeline' is a sequence of one or more commands separated by one of
+the control operators '|' or '|&'.
+
+   The format for a pipeline is
+     [time [-p]] [!] COMMAND1 [ | or |& COMMAND2 ] ...
+
+The output of each command in the pipeline is connected via a pipe to
+the input of the next command.  That is, each command reads the previous
+command's output.  This connection is performed before any redirections
+specified by COMMAND1.
+
+   If '|&' is used, COMMAND1's standard error, in addition to its
+standard output, is connected to COMMAND2's standard input through the
+pipe; it is shorthand for '2>&1 |'.  This implicit redirection of the
+standard error to the standard output is performed after any
+redirections specified by COMMAND1.
+
+   The reserved word 'time' causes timing statistics to be printed for
+the pipeline once it finishes.  The statistics currently consist of
+elapsed (wall-clock) time and user and system time consumed by the
+command's execution.  The '-p' option changes the output format to that
+specified by POSIX.  When the shell is in POSIX mode (*note Bash POSIX
+Mode::), it does not recognize 'time' as a reserved word if the next
+token begins with a '-'.  The 'TIMEFORMAT' variable may be set to a
+format string that specifies how the timing information should be
+displayed.  *Note Bash Variables::, for a description of the available
+formats.  The use of 'time' as a reserved word permits the timing of
+shell builtins, shell functions, and pipelines.  An external 'time'
+command cannot time these easily.
+
+   When the shell is in POSIX mode (*note Bash POSIX Mode::), 'time' may
+be followed by a newline.  In this case, the shell displays the total
+user and system time consumed by the shell and its children.  The
+'TIMEFORMAT' variable may be used to specify the format of the time
+information.
+
+   If the pipeline is not executed asynchronously (*note Lists::), the
+shell waits for all commands in the pipeline to complete.
+
+   Each command in a multi-command pipeline, where pipes are created, is
+executed in its own "subshell", which is a separate process (*note
+Command Execution Environment::).  If the 'lastpipe' option is enabled
+using the 'shopt' builtin (*note The Shopt Builtin::), the last element
+of a pipeline may be run by the shell process when job control is not
+active.
+
+   The exit status of a pipeline is the exit status of the last command
+in the pipeline, unless the 'pipefail' option is enabled (*note The Set
+Builtin::).  If 'pipefail' is enabled, the pipeline's return status is
+the value of the last (rightmost) command to exit with a non-zero
+status, or zero if all commands exit successfully.  If the reserved word
+'!' precedes the pipeline, the exit status is the logical negation of
+the exit status as described above.  The shell waits for all commands in
+the pipeline to terminate before returning a value.
+
+
+File: bash.info,  Node: Lists,  Next: Compound Commands,  Prev: Pipelines,  Up: Shell Commands
+
+3.2.4 Lists of Commands
+-----------------------
+
+A 'list' is a sequence of one or more pipelines separated by one of the
+operators ';', '&', '&&', or '||', and optionally terminated by one of
+';', '&', or a 'newline'.
+
+   Of these list operators, '&&' and '||' have equal precedence,
+followed by ';' and '&', which have equal precedence.
+
+   A sequence of one or more newlines may appear in a 'list' to delimit
+commands, equivalent to a semicolon.
+
+   If a command is terminated by the control operator '&', the shell
+executes the command asynchronously in a subshell.  This is known as
+executing the command in the "background", and these are referred to as
+"asynchronous" commands.  The shell does not wait for the command to
+finish, and the return status is 0 (true).  When job control is not
+active (*note Job Control::), the standard input for asynchronous
+commands, in the absence of any explicit redirections, is redirected
+from '/dev/null'.
+
+   Commands separated by a ';' are executed sequentially; the shell
+waits for each command to terminate in turn.  The return status is the
+exit status of the last command executed.
+
+   AND and OR lists are sequences of one or more pipelines separated by
+the control operators '&&' and '||', respectively.  AND and OR lists are
+executed with left associativity.
+
+   An AND list has the form
+     COMMAND1 && COMMAND2
+
+COMMAND2 is executed if, and only if, COMMAND1 returns an exit status of
+zero (success).
+
+   An OR list has the form
+     COMMAND1 || COMMAND2
+
+COMMAND2 is executed if, and only if, COMMAND1 returns a non-zero exit
+status.
+
+   The return status of AND and OR lists is the exit status of the last
+command executed in the list.

+
+* Menu:
+
+* Looping Constructs::		Shell commands for iterative action.
+* Conditional Constructs::	Shell commands for conditional execution.
+* Command Grouping::		Ways to group commands.
+
+Compound commands are the shell programming language constructs.  Each
+construct begins with a reserved word or control operator and is
+terminated by a corresponding reserved word or operator.  Any
+redirections (*note Redirections::) associated with a compound command
+apply to all commands within that compound command unless explicitly
+overridden.
+
+   In most cases a list of commands in a compound command's description
+may be separated from the rest of the command by one or more newlines,
+and may be followed by a newline in place of a semicolon.
+
+   Bash provides looping constructs, conditional commands, and
+mechanisms to group commands and execute them as a unit.
+
+
+File: bash.info,  Node: Looping Constructs,  Next: Conditional Constructs,  Up: Compound Commands
+
+3.2.5.1 Looping Constructs
+..........................
+
+Bash supports the following looping constructs.
+
+   Note that wherever a ';' appears in the description of a command's
+syntax, it may be replaced with one or more newlines.
+
+'until'
+     The syntax of the 'until' command is:
+
+          until TEST-COMMANDS; do CONSEQUENT-COMMANDS; done
+
+     Execute CONSEQUENT-COMMANDS as long as TEST-COMMANDS has an exit
+     status which is not zero.  The return status is the exit status of
+     the last command executed in CONSEQUENT-COMMANDS, or zero if none
+     was executed.
+
+'while'
+     The syntax of the 'while' command is:
+
+          while TEST-COMMANDS; do CONSEQUENT-COMMANDS; done
+
+     Execute CONSEQUENT-COMMANDS as long as TEST-COMMANDS has an exit
+     status of zero.  The return status is the exit status of the last
+     command executed in CONSEQUENT-COMMANDS, or zero if none was
+     executed.
+
+'for'
+     The syntax of the 'for' command is:
+
+          for NAME [ [in [WORDS ...] ] ; ] do COMMANDS; done
+
+     Expand WORDS (*note Shell Expansions::), and execute COMMANDS once
+     for each member in the resultant list, with NAME bound to the
+     current member.  If 'in WORDS' is not present, the 'for' command
+     executes the COMMANDS once for each positional parameter that is
+     set, as if 'in "$@"' had been specified (*note Special
+     Parameters::).
+
+     The return status is the exit status of the last command that
+     executes.  If there are no items in the expansion of WORDS, no
+     commands are executed, and the return status is zero.
+
+     An alternate form of the 'for' command is also supported:
+
+          for (( EXPR1 ; EXPR2 ; EXPR3 )) ; do COMMANDS ; done
+
+     First, the arithmetic expression EXPR1 is evaluated according to
+     the rules described below (*note Shell Arithmetic::).  The
+     arithmetic expression EXPR2 is then evaluated repeatedly until it
+     evaluates to zero.  Each time EXPR2 evaluates to a non-zero value,
+     COMMANDS are executed and the arithmetic expression EXPR3 is
+     evaluated.  If any expression is omitted, it behaves as if it
+     evaluates to 1.  The return value is the exit status of the last
+     command in COMMANDS that is executed, or false if any of the
+     expressions is invalid.
+
+   The 'break' and 'continue' builtins (*note Bourne Shell Builtins::)
+may be used to control loop execution.
+
+
+File: bash.info,  Node: Conditional Constructs,  Next: Command Grouping,  Prev: Looping Constructs,  Up: Compound Commands
+
+3.2.5.2 Conditional Constructs
+..............................
+
+'if'
+     The syntax of the 'if' command is:
+
+          if TEST-COMMANDS; then
+            CONSEQUENT-COMMANDS;
+          [elif MORE-TEST-COMMANDS; then
+            MORE-CONSEQUENTS;]
+          [else ALTERNATE-CONSEQUENTS;]
+          fi
+
+     The TEST-COMMANDS list is executed, and if its return status is
+     zero, the CONSEQUENT-COMMANDS list is executed.  If TEST-COMMANDS
+     returns a non-zero status, each 'elif' list is executed in turn,
+     and if its exit status is zero, the corresponding MORE-CONSEQUENTS
+     is executed and the command completes.  If 'else
+     ALTERNATE-CONSEQUENTS' is present, and the final command in the
+     final 'if' or 'elif' clause has a non-zero exit status, then
+     ALTERNATE-CONSEQUENTS is executed.  The return status is the exit
+     status of the last command executed, or zero if no condition tested
+     true.
+
+'case'
+     The syntax of the 'case' command is:
+
+          case WORD in
+              [ [(] PATTERN [| PATTERN]...) COMMAND-LIST ;;]...
+          esac
+
+     'case' will selectively execute the COMMAND-LIST corresponding to
+     the first PATTERN that matches WORD.  The match is performed
+     according to the rules described below in *note Pattern Matching::.
+     If the 'nocasematch' shell option (see the description of 'shopt'
+     in *note The Shopt Builtin::) is enabled, the match is performed
+     without regard to the case of alphabetic characters.  The '|' is
+     used to separate multiple patterns, and the ')' operator terminates
+     a pattern list.  A list of patterns and an associated command-list
+     is known as a CLAUSE.
+
+     Each clause must be terminated with ';;', ';&', or ';;&'.  The WORD
+     undergoes tilde expansion, parameter expansion, command
+     substitution, arithmetic expansion, and quote removal (*note Shell
+     Parameter Expansion::) before matching is attempted.  Each PATTERN
+     undergoes tilde expansion, parameter expansion, command
+     substitution, arithmetic expansion, process substitution, and quote
+     removal.
+
+     There may be an arbitrary number of 'case' clauses, each terminated
+     by a ';;', ';&', or ';;&'.  The first pattern that matches
+     determines the command-list that is executed.  It's a common idiom
+     to use '*' as the final pattern to define the default case, since
+     that pattern will always match.
+
+     Here is an example using 'case' in a script that could be used to
+     describe one interesting feature of an animal:
+
+          echo -n "Enter the name of an animal: "
+          read ANIMAL
+          echo -n "The $ANIMAL has "
+          case $ANIMAL in
+            horse | dog | cat) echo -n "four";;
+            man | kangaroo ) echo -n "two";;
+            *) echo -n "an unknown number of";;
+          esac
+          echo " legs."
+
+
+     If the ';;' operator is used, no subsequent matches are attempted
+     after the first pattern match.  Using ';&' in place of ';;' causes
+     execution to continue with the COMMAND-LIST associated with the
+     next clause, if any.  Using ';;&' in place of ';;' causes the shell
+     to test the patterns in the next clause, if any, and execute any
+     associated COMMAND-LIST on a successful match, continuing the case
+     statement execution as if the pattern list had not matched.
+
+     The return status is zero if no PATTERN is matched.  Otherwise, the
+     return status is the exit status of the COMMAND-LIST executed.
+
+'select'
+
+     The 'select' construct allows the easy generation of menus.  It has
+     almost the same syntax as the 'for' command:
+
+          select NAME [in WORDS ...]; do COMMANDS; done
+
+     The list of words following 'in' is expanded, generating a list of
+     items, and the set of expanded words is printed on the standard
+     error output stream, each preceded by a number.  If the 'in WORDS'
+     is omitted, the positional parameters are printed, as if 'in "$@"'
+     had been specified.  'select' then displays the 'PS3' prompt and
+     reads a line from the standard input.  If the line consists of a
+     number corresponding to one of the displayed words, then the value
+     of NAME is set to that word.  If the line is empty, the words and
+     prompt are displayed again.  If 'EOF' is read, the 'select' command
+     completes and returns 1.  Any other value read causes NAME to be
+     set to null.  The line read is saved in the variable 'REPLY'.
+
+     The COMMANDS are executed after each selection until a 'break'
+     command is executed, at which point the 'select' command completes.
+
+     Here is an example that allows the user to pick a filename from the
+     current directory, and displays the name and index of the file
+     selected.
+
+          select fname in *;
+          do
+          	echo you picked $fname \($REPLY\)
+          	break;
+          done
+
+'((...))'
+          (( EXPRESSION ))
+
+     The arithmetic EXPRESSION is evaluated according to the rules
+     described below (*note Shell Arithmetic::).  The EXPRESSION
+     undergoes the same expansions as if it were within double quotes,
+     but double quote characters in EXPRESSION are not treated specially
+     are removed.  If the value of the expression is non-zero, the
+     return status is 0; otherwise the return status is 1.
+
+'[[...]]'
+          [[ EXPRESSION ]]
+
+     Return a status of 0 or 1 depending on the evaluation of the
+     conditional expression EXPRESSION.  Expressions are composed of the
+     primaries described below in *note Bash Conditional Expressions::.
+     The words between the '[[' and ']]' do not undergo word splitting
+     and filename expansion.  The shell performs tilde expansion,
+     parameter and variable expansion, arithmetic expansion, command
+     substitution, process substitution, and quote removal on those
+     words (the expansions that would occur if the words were enclosed
+     in double quotes).  Conditional operators such as '-f' must be
+     unquoted to be recognized as primaries.
+
+     When used with '[[', the '<' and '>' operators sort
+     lexicographically using the current locale.
+
+     When the '==' and '!=' operators are used, the string to the right
+     of the operator is considered a pattern and matched according to
+     the rules described below in *note Pattern Matching::, as if the
+     'extglob' shell option were enabled.  The '=' operator is identical
+     to '=='.  If the 'nocasematch' shell option (see the description of
+     'shopt' in *note The Shopt Builtin::) is enabled, the match is
+     performed without regard to the case of alphabetic characters.  The
+     return value is 0 if the string matches ('==') or does not match
+     ('!=') the pattern, and 1 otherwise.
+
+     If you quote any part of the pattern, using any of the shell's
+     quoting mechanisms, the quoted portion is matched literally.  This
+     means every character in the quoted portion matches itself, instead
+     of having any special pattern matching meaning.
+
+     An additional binary operator, '=~', is available, with the same
+     precedence as '==' and '!='.  When you use '=~', the string to the
+     right of the operator is considered a POSIX extended regular
+     expression pattern and matched accordingly (using the POSIX
+     'regcomp' and 'regexec' interfaces usually described in regex(3)).
+     The return value is 0 if the string matches the pattern, and 1 if
+     it does not.  If the regular expression is syntactically incorrect,
+     the conditional expression returns 2.  If the 'nocasematch' shell
+     option (see the description of 'shopt' in *note The Shopt
+     Builtin::) is enabled, the match is performed without regard to the
+     case of alphabetic characters.
+
+     You can quote any part of the pattern to force the quoted portion
+     to be matched literally instead of as a regular expression (see
+     above).  If the pattern is stored in a shell variable, quoting the
+     variable expansion forces the entire pattern to be matched
+     literally.
+
+     The pattern will match if it matches any part of the string.  If
+     you want to force the pattern to match the entire string, anchor
+     the pattern using the '^' and '$' regular expression operators.
+
+     For example, the following will match a line (stored in the shell
+     variable 'line') if there is a sequence of characters anywhere in
+     the value consisting of any number, including zero, of characters
+     in the 'space' character class, immediately followed by zero or one
+     instances of 'a', then a 'b':
+
+          [[ $line =~ [[:space:]]*(a)?b ]]
+
+     That means values for 'line' like 'aab', ' aaaaaab', 'xaby', and '
+     ab' will all match, as will a line containing a 'b' anywhere in its
+     value.
+
+     If you want to match a character that's special to the regular
+     expression grammar ('^$|[]()\.*+?'), it has to be quoted to remove
+     its special meaning.  This means that in the pattern 'xxx.txt', the
+     '.' matches any character in the string (its usual regular
+     expression meaning), but in the pattern '"xxx.txt"', it can only
+     match a literal '.'.
+
+     Likewise, if you want to include a character in your pattern that
+     has a special meaning to the regular expression grammar, you must
+     make sure it's not quoted.  If you want to anchor a pattern at the
+     beginning or end of the string, for instance, you cannot quote the
+     '^' or '$' characters using any form of shell quoting.
+
+     If you want to match 'initial string' at the start of a line, the
+     following will work:
+          [[ $line =~ ^"initial string" ]]
+     but this will not:
+          [[ $line =~ "^initial string" ]]
+     because in the second example the '^' is quoted and doesn't have
+     its usual special meaning.
+
+     It is sometimes difficult to specify a regular expression properly
+     without using quotes, or to keep track of the quoting used by
+     regular expressions while paying attention to shell quoting and the
+     shell's quote removal.  Storing the regular expression in a shell
+     variable is often a useful way to avoid problems with quoting
+     characters that are special to the shell.  For example, the
+     following is equivalent to the pattern used above:
+
+          pattern='[[:space:]]*(a)?b'
+          [[ $line =~ $pattern ]]
+
+     Shell programmers should take special care with backslashes, since
+     backslashes are used by both the shell and regular expressions to
+     remove the special meaning from the following character.  This
+     means that after the shell's word expansions complete (*note Shell
+     Expansions::), any backslashes remaining in parts of the pattern
+     that were originally not quoted can remove the special meaning of
+     pattern characters.  If any part of the pattern is quoted, the
+     shell does its best to ensure that the regular expression treats
+     those remaining backslashes as literal, if they appeared in a
+     quoted portion.
+
+     The following two sets of commands are _not_ equivalent:
+
+          pattern='\.'
+
+          [[ . =~ $pattern ]]
+          [[ . =~ \. ]]
+
+          [[ . =~ "$pattern" ]]
+          [[ . =~ '\.' ]]
+
+     The first two matches will succeed, but the second two will not,
+     because in the second two the backslash will be part of the pattern
+     to be matched.  In the first two examples, the pattern passed to
+     the regular expression parser is '\.'.  The backslash removes the
+     special meaning from '.', so the literal '.' matches.  In the
+     second two examples, the pattern passed to the regular expression
+     parser has the backslash quoted (e.g., '\\\.'), which will not
+     match the string, since it does not contain a backslash.  If the
+     string in the first examples were anything other than '.', say 'a',
+     the pattern would not match, because the quoted '.' in the pattern
+     loses its special meaning of matching any single character.
+
+     Bracket expressions in regular expressions can be sources of errors
+     as well, since characters that are normally special in regular
+     expressions lose their special meanings between brackets.  However,
+     you can use bracket expressions to match special pattern characters
+     without quoting them, so they are sometimes useful for this
+     purpose.
+
+     Though it might seem like a strange way to write it, the following
+     pattern will match a '.' in the string:
+
+          [[ . =~ [.] ]]
+
+     The shell performs any word expansions before passing the pattern
+     to the regular expression functions, so you can assume that the
+     shell's quoting takes precedence.  As noted above, the regular
+     expression parser will interpret any unquoted backslashes remaining
+     in the pattern after shell expansion according to its own rules.
+     The intention is to avoid making shell programmers quote things
+     twice as much as possible, so shell quoting should be sufficient to
+     quote special pattern characters where that's necessary.
+
+     The array variable 'BASH_REMATCH' records which parts of the string
+     matched the pattern.  The element of 'BASH_REMATCH' with index 0
+     contains the portion of the string matching the entire regular
+     expression.  Substrings matched by parenthesized subexpressions
+     within the regular expression are saved in the remaining
+     'BASH_REMATCH' indices.  The element of 'BASH_REMATCH' with index N
+     is the portion of the string matching the Nth parenthesized
+     subexpression.
+
+     Bash sets 'BASH_REMATCH' in the global scope; declaring it as a
+     local variable will lead to unexpected results.
+
+     Expressions may be combined using the following operators, listed
+     in decreasing order of precedence:
+
+     '( EXPRESSION )'
+          Returns the value of EXPRESSION.  This may be used to override
+          the normal precedence of operators.
+
+     '! EXPRESSION'
+          True if EXPRESSION is false.
+
+     'EXPRESSION1 && EXPRESSION2'
+          True if both EXPRESSION1 and EXPRESSION2 are true.
+
+     'EXPRESSION1 || EXPRESSION2'
+          True if either EXPRESSION1 or EXPRESSION2 is true.
+
+     The '&&' and '||' operators do not evaluate EXPRESSION2 if the
+     value of EXPRESSION1 is sufficient to determine the return value of
+     the entire conditional expression.

+
+3.2.5.3 Grouping Commands
+.........................
+
+Bash provides two ways to group a list of commands to be executed as a
+unit.  When commands are grouped, redirections may be applied to the
+entire command list.  For example, the output of all the commands in the
+list may be redirected to a single stream.
+
+'()'
+          ( LIST )
+
+     Placing a list of commands between parentheses forces the shell to
+     create a subshell (*note Command Execution Environment::), and each
+     of the commands in LIST is executed in that subshell environment.
+     Since the LIST is executed in a subshell, variable assignments do
+     not remain in effect after the subshell completes.
+
+'{}'
+          { LIST; }
+
+     Placing a list of commands between curly braces causes the list to
+     be executed in the current shell context.  No subshell is created.
+     The semicolon (or newline) following LIST is required.
+
+   In addition to the creation of a subshell, there is a subtle
+difference between these two constructs due to historical reasons.  The
+braces are reserved words, so they must be separated from the LIST by
+'blank's or other shell metacharacters.  The parentheses are operators,
+and are recognized as separate tokens by the shell even if they are not
+separated from the LIST by whitespace.
+
+   The exit status of both of these constructs is the exit status of
+LIST.

+
+File: bash.info,  Node: Coprocesses,  Next: GNU Parallel,  Prev: Compound Commands,  Up: Shell Commands
+
+3.2.6 Coprocesses
+-----------------
+
+A 'coprocess' is a shell command preceded by the 'coproc' reserved word.
+A coprocess is executed asynchronously in a subshell, as if the command
+had been terminated with the '&' control operator, with a two-way pipe
+established between the executing shell and the coprocess.
+
+   The syntax for a coprocess is:
+
+     coproc [NAME] COMMAND [REDIRECTIONS]
+
+This creates a coprocess named NAME.  COMMAND may be either a simple
+command (*note Simple Commands::) or a compound command (*note Compound
+Commands::).  NAME is a shell variable name.  If NAME is not supplied,
+the default name is 'COPROC'.
+
+   The recommended form to use for a coprocess is
+
+     coproc NAME { COMMAND; }
+
+This form is recommended because simple commands result in the coprocess
+always being named 'COPROC', and it is simpler to use and more complete
+than the other compound commands.
+
+   There are other forms of coprocesses:
+
+     coproc NAME COMPOUND-COMMAND
+     coproc COMPOUND-COMMAND
+     coproc SIMPLE-COMMAND
+
+If COMMAND is a compound command, NAME is optional.  The word following
+'coproc' determines whether that word is interpreted as a variable name:
+it is interpreted as NAME if it is not a reserved word that introduces a
+compound command.  If COMMAND is a simple command, NAME is not allowed;
+this is to avoid confusion between NAME and the first word of the simple
+command.
+
+   When the coprocess is executed, the shell creates an array variable
+(*note Arrays::) named NAME in the context of the executing shell.  The
+standard output of COMMAND is connected via a pipe to a file descriptor
+in the executing shell, and that file descriptor is assigned to NAME[0].
+The standard input of COMMAND is connected via a pipe to a file
+descriptor in the executing shell, and that file descriptor is assigned
+to NAME[1].  This pipe is established before any redirections specified
+by the command (*note Redirections::).  The file descriptors can be
+utilized as arguments to shell commands and redirections using standard
+word expansions.  Other than those created to execute command and
+process substitutions, the file descriptors are not available in
+subshells.
+
+   The process ID of the shell spawned to execute the coprocess is
+available as the value of the variable 'NAME_PID'.  The 'wait' builtin
+command may be used to wait for the coprocess to terminate.
+
+   Since the coprocess is created as an asynchronous command, the
+'coproc' command always returns success.  The return status of a
+coprocess is the exit status of COMMAND.

+3.2.7 GNU Parallel
+------------------
+
+There are ways to run commands in parallel that are not built into Bash.
+GNU Parallel is a tool to do just that.
+
+   GNU Parallel, as its name suggests, can be used to build and run
+commands in parallel.  You may run the same command with different
+arguments, whether they are filenames, usernames, hostnames, or lines
+read from files.  GNU Parallel provides shorthand references to many of
+the most common operations (input lines, various portions of the input
+line, different ways to specify the input source, and so on).  Parallel
+can replace 'xargs' or feed commands from its input sources to several
+different instances of Bash.
+
+   For a complete description, refer to the GNU Parallel documentation,
+which is available at
+<https://www.gnu.org/software/parallel/parallel_tutorial.html>.

+File: bash.info,  Node: Shell Functions,  Next: Shell Parameters,  Prev: Shell Commands,  Up: Basic Shell Features
+
+3.3 Shell Functions
+===================
+
+Shell functions are a way to group commands for later execution using a
+single name for the group.  They are executed just like a "regular"
+command.  When the name of a shell function is used as a simple command
+name, the list of commands associated with that function name is
+executed.  Shell functions are executed in the current shell context; no
+new process is created to interpret them.
+
+   Functions are declared using this syntax:
+     FNAME () COMPOUND-COMMAND [ REDIRECTIONS ]
+
+   or
+
+     function FNAME [()] COMPOUND-COMMAND [ REDIRECTIONS ]
+
+   This defines a shell function named FNAME.  The reserved word
+'function' is optional.  If the 'function' reserved word is supplied,
+the parentheses are optional.  The "body" of the function is the
+compound command COMPOUND-COMMAND (*note Compound Commands::).  That
+command is usually a LIST enclosed between { and }, but may be any
+compound command listed above.  If the 'function' reserved word is used,
+but the parentheses are not supplied, the braces are recommended.
+COMPOUND-COMMAND is executed whenever FNAME is specified as the name of
+a simple command.  When the shell is in POSIX mode (*note Bash POSIX
+Mode::), FNAME must be a valid shell name and may not be the same as one
+of the special builtins (*note Special Builtins::).  In default mode, a
+function name can be any unquoted shell word that does not contain '$'.
+Any redirections (*note Redirections::) associated with the shell
+function are performed when the function is executed.  A function
+definition may be deleted using the '-f' option to the 'unset' builtin
+(*note Bourne Shell Builtins::).
+
+   The exit status of a function definition is zero unless a syntax
+error occurs or a readonly function with the same name already exists.
+When executed, the exit status of a function is the exit status of the
+last command executed in the body.
+
+   Note that for historical reasons, in the most common usage the curly
+braces that surround the body of the function must be separated from the
+body by 'blank's or newlines.  This is because the braces are reserved
+words and are only recognized as such when they are separated from the
+command list by whitespace or another shell metacharacter.  Also, when
+using the braces, the LIST must be terminated by a semicolon, a '&', or
+a newline.
+
+   When a function is executed, the arguments to the function become the
+positional parameters during its execution (*note Positional
+Parameters::).  The special parameter '#' that expands to the number of
+positional parameters is updated to reflect the change.  Special
+parameter '0' is unchanged.  The first element of the 'FUNCNAME'
+variable is set to the name of the function while the function is
+executing.
+
+   All other aspects of the shell execution environment are identical
+between a function and its caller with these exceptions: the 'DEBUG' and
+'RETURN' traps are not inherited unless the function has been given the
+'trace' attribute using the 'declare' builtin or the '-o functrace'
+option has been enabled with the 'set' builtin, (in which case all
+functions inherit the 'DEBUG' and 'RETURN' traps), and the 'ERR' trap is
+not inherited unless the '-o errtrace' shell option has been enabled.
+*Note Bourne Shell Builtins::, for the description of the 'trap'
+builtin.
+
+   The 'FUNCNEST' variable, if set to a numeric value greater than 0,
+defines a maximum function nesting level.  Function invocations that
+exceed the limit cause the entire command to abort.
+
+   If the builtin command 'return' is executed in a function, the
+function completes and execution resumes with the next command after the
+function call.  Any command associated with the 'RETURN' trap is
+executed before execution resumes.  When a function completes, the
+values of the positional parameters and the special parameter '#' are
+restored to the values they had prior to the function's execution.  If a
+numeric argument is given to 'return', that is the function's return
+status; otherwise the function's return status is the exit status of the
+last command executed before the 'return'.
+
+   Variables local to the function may be declared with the 'local'
+builtin ("local variables").  Ordinarily, variables and their values are
+shared between a function and its caller.  These variables are visible
+only to the function and the commands it invokes.  This is particularly
+important when a shell function calls other functions.
+
+   In the following description, the "current scope" is a currently-
+executing function.  Previous scopes consist of that function's caller
+and so on, back to the "global" scope, where the shell is not executing
+any shell function.  Consequently, a local variable at the current local
+scope is a variable declared using the 'local' or 'declare' builtins in
+the function that is currently executing.
+
+   Local variables "shadow" variables with the same name declared at
+previous scopes.  For instance, a local variable declared in a function
+hides a global variable of the same name: references and assignments
+refer to the local variable, leaving the global variable unmodified.
+When the function returns, the global variable is once again visible.
+
+   The shell uses "dynamic scoping" to control a variable's visibility
+within functions.  With dynamic scoping, visible variables and their
+values are a result of the sequence of function calls that caused
+execution to reach the current function.  The value of a variable that a
+function sees depends on its value within its caller, if any, whether
+that caller is the "global" scope or another shell function.  This is
+also the value that a local variable declaration "shadows", and the
+value that is restored when the function returns.
+
+   For example, if a variable 'var' is declared as local in function
+'func1', and 'func1' calls another function 'func2', references to 'var'
+made from within 'func2' will resolve to the local variable 'var' from
+'func1', shadowing any global variable named 'var'.
+
+   The following script demonstrates this behavior.  When executed, the
+script displays
+
+     In func2, var = func1 local
+
+     func1()
+     {
+         local var='func1 local'
+         func2
+     }
+
+     func2()
+     {
+         echo "In func2, var = $var"
+     }
+
+     var=global
+     func1
+
+   The 'unset' builtin also acts using the same dynamic scope: if a
+variable is local to the current scope, 'unset' will unset it; otherwise
+the unset will refer to the variable found in any calling scope as
+described above.  If a variable at the current local scope is unset, it
+will remain so (appearing as unset) until it is reset in that scope or
+until the function returns.  Once the function returns, any instance of
+the variable at a previous scope will become visible.  If the unset acts
+on a variable at a previous scope, any instance of a variable with that
+name that had been shadowed will become visible (see below how
+'localvar_unset'shell option changes this behavior).
+
+   Function names and definitions may be listed with the '-f' option to
+the 'declare' ('typeset') builtin command (*note Bash Builtins::).  The
+'-F' option to 'declare' or 'typeset' will list the function names only
+(and optionally the source file and line number, if the 'extdebug' shell
+option is enabled).  Functions may be exported so that child shell
+processes (those created when executing a separate shell invocation)
+automatically have them defined with the '-f' option to the 'export'
+builtin (*note Bourne Shell Builtins::).
+
+   Functions may be recursive.  The 'FUNCNEST' variable may be used to
+limit the depth of the function call stack and restrict the number of
+function invocations.  By default, no limit is placed on the number of
+recursive calls.

+
+3.4 Shell Parameters
+====================
+
+* Menu:
+
+* Positional Parameters::	The shell's command-line arguments.
+* Special Parameters::		Parameters denoted by special characters.
+
+A "parameter" is an entity that stores values.  It can be a 'name', a
+number, or one of the special characters listed below.  A "variable" is
+a parameter denoted by a 'name'.  A variable has a 'value' and zero or
+more 'attributes'.  Attributes are assigned using the 'declare' builtin
+command (see the description of the 'declare' builtin in *note Bash
+Builtins::).
+
+   A parameter is set if it has been assigned a value.  The null string
+is a valid value.  Once a variable is set, it may be unset only by using
+the 'unset' builtin command.
+
+   A variable may be assigned to by a statement of the form
+     NAME=[VALUE]
+If VALUE is not given, the variable is assigned the null string.  All
+VALUEs undergo tilde expansion, parameter and variable expansion,
+command substitution, arithmetic expansion, and quote removal (*note
+Shell Parameter Expansion::).  If the variable has its 'integer'
+attribute set, then VALUE is evaluated as an arithmetic expression even
+if the '$((...))' expansion is not used (*note Arithmetic Expansion::).
+Word splitting and filename expansion are not performed.  Assignment
+statements may also appear as arguments to the 'alias', 'declare',
+'typeset', 'export', 'readonly', and 'local' builtin commands
+("declaration" commands).  When in POSIX mode (*note Bash POSIX Mode::),
+these builtins may appear in a command after one or more instances of
+the 'command' builtin and retain these assignment statement properties.
+
+   In the context where an assignment statement is assigning a value to
+a shell variable or array index (*note Arrays::), the '+=' operator can
+be used to append to or add to the variable's previous value.  This
+includes arguments to builtin commands such as 'declare' that accept
+assignment statements (declaration commands).  When '+=' is applied to a
+variable for which the 'integer' attribute has been set, VALUE is
+evaluated as an arithmetic expression and added to the variable's
+current value, which is also evaluated.  When '+=' is applied to an
+array variable using compound assignment (*note Arrays::), the
+variable's value is not unset (as it is when using '='), and new values
+are appended to the array beginning at one greater than the array's
+maximum index (for indexed arrays), or added as additional key-value
+pairs in an associative array.  When applied to a string-valued
+variable, VALUE is expanded and appended to the variable's value.
+
+   A variable can be assigned the 'nameref' attribute using the '-n'
+option to the 'declare' or 'local' builtin commands (*note Bash
+Builtins::) to create a "nameref", or a reference to another variable.
+This allows variables to be manipulated indirectly.  Whenever the
+nameref variable is referenced, assigned to, unset, or has its
+attributes modified (other than using or changing the nameref attribute
+itself), the operation is actually performed on the variable specified
+by the nameref variable's value.  A nameref is commonly used within
+shell functions to refer to a variable whose name is passed as an
+argument to the function.  For instance, if a variable name is passed to
+a shell function as its first argument, running
+     declare -n ref=$1
+inside the function creates a nameref variable 'ref' whose value is the
+variable name passed as the first argument.  References and assignments
+to 'ref', and changes to its attributes, are treated as references,
+assignments, and attribute modifications to the variable whose name was
+passed as '$1'.
+
+   If the control variable in a 'for' loop has the nameref attribute,
+the list of words can be a list of shell variables, and a name reference
+will be established for each word in the list, in turn, when the loop is
+executed.  Array variables cannot be given the nameref attribute.
+However, nameref variables can reference array variables and subscripted
+array variables.  Namerefs can be unset using the '-n' option to the
+'unset' builtin (*note Bourne Shell Builtins::).  Otherwise, if 'unset'
+is executed with the name of a nameref variable as an argument, the
+variable referenced by the nameref variable will be unset.
+
+
+File: bash.info,  Node: Positional Parameters,  Next: Special Parameters,  Up: Shell Parameters
+
+3.4.1 Positional Parameters
+---------------------------
+
+A "positional parameter" is a parameter denoted by one or more digits,
+other than the single digit '0'.  Positional parameters are assigned
+from the shell's arguments when it is invoked, and may be reassigned
+using the 'set' builtin command.  Positional parameter 'N' may be
+referenced as '${N}', or as '$N' when 'N' consists of a single digit.
+Positional parameters may not be assigned to with assignment statements.
+The 'set' and 'shift' builtins are used to set and unset them (*note
+Shell Builtin Commands::).  The positional parameters are temporarily
+replaced when a shell function is executed (*note Shell Functions::).
+
+   When a positional parameter consisting of more than a single digit is
+expanded, it must be enclosed in braces.
+
+
+File: bash.info,  Node: Special Parameters,  Prev: Positional Parameters,  Up: Shell Parameters
+
+3.4.2 Special Parameters
+------------------------
+
+The shell treats several parameters specially.  These parameters may
+only be referenced; assignment to them is not allowed.
+
+'*'
+     ($*) Expands to the positional parameters, starting from one.  When
+     the expansion is not within double quotes, each positional
+     parameter expands to a separate word.  In contexts where it is
+     performed, those words are subject to further word splitting and
+     filename expansion.  When the expansion occurs within double
+     quotes, it expands to a single word with the value of each
+     parameter separated by the first character of the 'IFS' special
+     variable.  That is, '"$*"' is equivalent to '"$1C$2C..."', where C
+     is the first character of the value of the 'IFS' variable.  If
+     'IFS' is unset, the parameters are separated by spaces.  If 'IFS'
+     is null, the parameters are joined without intervening separators.
+
+'@'
+     ($@) Expands to the positional parameters, starting from one.  In
+     contexts where word splitting is performed, this expands each
+     positional parameter to a separate word; if not within double
+     quotes, these words are subject to word splitting.  In contexts
+     where word splitting is not performed, this expands to a single
+     word with each positional parameter separated by a space.  When the
+     expansion occurs within double quotes, and word splitting is
+     performed, each parameter expands to a separate word.  That is,
+     '"$@"' is equivalent to '"$1" "$2" ...'.  If the double-quoted
+     expansion occurs within a word, the expansion of the first
+     parameter is joined with the beginning part of the original word,
+     and the expansion of the last parameter is joined with the last
+     part of the original word.  When there are no positional
+     parameters, '"$@"' and '$@' expand to nothing (i.e., they are
+     removed).
+
+'#'
+     ($#) Expands to the number of positional parameters in decimal.
+
+'?'
+     ($?)  Expands to the exit status of the most recently executed
+     foreground pipeline.
+
+'-'
+     ($-, a hyphen.)  Expands to the current option flags as specified
+     upon invocation, by the 'set' builtin command, or those set by the
+     shell itself (such as the '-i' option).
+
+'$'
+     ($$) Expands to the process ID of the shell.  In a subshell, it
+     expands to the process ID of the invoking shell, not the subshell.
+
+'!'
+     ($!)  Expands to the process ID of the job most recently placed
+     into the background, whether executed as an asynchronous command or
+     using the 'bg' builtin (*note Job Control Builtins::).
+
+'0'
+     ($0) Expands to the name of the shell or shell script.  This is set
+     at shell initialization.  If Bash is invoked with a file of
+     commands (*note Shell Scripts::), '$0' is set to the name of that
+     file.  If Bash is started with the '-c' option (*note Invoking
+     Bash::), then '$0' is set to the first argument after the string to
+     be executed, if one is present.  Otherwise, it is set to the
+     filename used to invoke Bash, as given by argument zero.

+
+3.5 Shell Expansions
+====================
+
+Expansion is performed on the command line after it has been split into
+'token's.  There are seven kinds of expansion performed:
+
+   * brace expansion
+   * tilde expansion
+   * parameter and variable expansion
+   * command substitution
+   * arithmetic expansion
+   * word splitting
+   * filename expansion
+
+* Menu:
+
+* Brace Expansion::		Expansion of expressions within braces.
+* Tilde Expansion::		Expansion of the ~ character.
+* Shell Parameter Expansion::	How Bash expands variables to their values.
+* Command Substitution::	Using the output of a command as an argument.
+* Arithmetic Expansion::	How to use arithmetic in shell expansions.
+* Process Substitution::	A way to write and read to and from a
+				command.
+* Word Splitting::	How the results of expansion are split into separate
+			arguments.
+* Filename Expansion::	A shorthand for specifying filenames matching patterns.
+* Quote Removal::	How and when quote characters are removed from
+			words.
+
+   The order of expansions is: brace expansion; tilde expansion,
+parameter and variable expansion, arithmetic expansion, and command
+substitution (done in a left-to-right fashion); word splitting; and
+filename expansion.
+
+   On systems that can support it, there is an additional expansion
+available: "process substitution".  This is performed at the same time
+as tilde, parameter, variable, and arithmetic expansion and command
+substitution.
+
+   After these expansions are performed, quote characters present in the
+original word are removed unless they have been quoted themselves
+("quote removal").
+
+   Only brace expansion, word splitting, and filename expansion can
+increase the number of words of the expansion; other expansions expand a
+single word to a single word.  The only exceptions to this are the
+expansions of '"$@"' and '$*' (*note Special Parameters::), and
+'"${NAME[@]}"' and '${NAME[*]}' (*note Arrays::).
+
+   After all expansions, 'quote removal' (*note Quote Removal::) is
+performed.

+
+3.5.1 Brace Expansion
+---------------------
+
+Brace expansion is a mechanism by which arbitrary strings may be
+generated.  This mechanism is similar to "filename expansion" (*note
+Filename Expansion::), but the filenames generated need not exist.
+Patterns to be brace expanded take the form of an optional PREAMBLE,
+followed by either a series of comma-separated strings or a sequence
+expression between a pair of braces, followed by an optional POSTSCRIPT.
+The preamble is prefixed to each string contained within the braces, and
+the postscript is then appended to each resulting string, expanding left
+to right.
+
+   Brace expansions may be nested.  The results of each expanded string
+are not sorted; left to right order is preserved.  For example,
+     bash$ echo a{d,c,b}e
+     ade ace abe
+
+   A sequence expression takes the form '{X..Y[..INCR]}', where X and Y
+are either integers or letters, and INCR, an optional increment, is an
+integer.  When integers are supplied, the expression expands to each
+number between X and Y, inclusive.  Supplied integers may be prefixed
+with '0' to force each term to have the same width.  When either X or Y
+begins with a zero, the shell attempts to force all generated terms to
+contain the same number of digits, zero-padding where necessary.  When
+letters are supplied, the expression expands to each character
+lexicographically between X and Y, inclusive, using the default C
+locale.  Note that both X and Y must be of the same type (integer or
+letter).  When the increment is supplied, it is used as the difference
+between each term.  The default increment is 1 or -1 as appropriate.
+
+   Brace expansion is performed before any other expansions, and any
+characters special to other expansions are preserved in the result.  It
+is strictly textual.  Bash does not apply any syntactic interpretation
+to the context of the expansion or the text between the braces.
+
+   A correctly-formed brace expansion must contain unquoted opening and
+closing braces, and at least one unquoted comma or a valid sequence
+expression.  Any incorrectly formed brace expansion is left unchanged.
+
+   A { or ',' may be quoted with a backslash to prevent its being
+considered part of a brace expression.  To avoid conflicts with
+parameter expansion, the string '${' is not considered eligible for
+brace expansion, and inhibits brace expansion until the closing '}'.
+
+   This construct is typically used as shorthand when the common prefix
+of the strings to be generated is longer than in the above example:
+     mkdir /usr/local/src/bash/{old,new,dist,bugs}
+   or
+     chown root /usr/{ucb/{ex,edit},lib/{ex?.?*,how_ex}}

+
+3.5.2 Tilde Expansion
+---------------------
+
+If a word begins with an unquoted tilde character ('~'), all of the
+characters up to the first unquoted slash (or all characters, if there
+is no unquoted slash) are considered a "tilde-prefix".  If none of the
+characters in the tilde-prefix are quoted, the characters in the
+tilde-prefix following the tilde are treated as a possible "login name".
+If this login name is the null string, the tilde is replaced with the
+value of the 'HOME' shell variable.  If 'HOME' is unset, the home
+directory of the user executing the shell is substituted instead.
+Otherwise, the tilde-prefix is replaced with the home directory
+associated with the specified login name.
+
+   If the tilde-prefix is '~+', the value of the shell variable 'PWD'
+replaces the tilde-prefix.  If the tilde-prefix is '~-', the value of
+the shell variable 'OLDPWD', if it is set, is substituted.
+
+   If the characters following the tilde in the tilde-prefix consist of
+a number N, optionally prefixed by a '+' or a '-', the tilde-prefix is
+replaced with the corresponding element from the directory stack, as it
+would be displayed by the 'dirs' builtin invoked with the characters
+following tilde in the tilde-prefix as an argument (*note The Directory
+Stack::).  If the tilde-prefix, sans the tilde, consists of a number
+without a leading '+' or '-', '+' is assumed.
+
+   If the login name is invalid, or the tilde expansion fails, the word
+is left unchanged.
+
+   Each variable assignment is checked for unquoted tilde-prefixes
+immediately following a ':' or the first '='.  In these cases, tilde
+expansion is also performed.  Consequently, one may use filenames with
+tildes in assignments to 'PATH', 'MAILPATH', and 'CDPATH', and the shell
+assigns the expanded value.
+
+   The following table shows how Bash treats unquoted tilde-prefixes:
+
+'~'
+     The value of '$HOME'
+'~/foo'
+     '$HOME/foo'
+
+'~fred/foo'
+     The subdirectory 'foo' of the home directory of the user 'fred'
+
+'~+/foo'
+     '$PWD/foo'
+
+'~-/foo'
+     '${OLDPWD-'~-'}/foo'
+
+'~N'
+     The string that would be displayed by 'dirs +N'
+
+'~+N'
+     The string that would be displayed by 'dirs +N'
+
+'~-N'
+     The string that would be displayed by 'dirs -N'
+
+   Bash also performs tilde expansion on words satisfying the conditions
+of variable assignments (*note Shell Parameters::) when they appear as
+arguments to simple commands.  Bash does not do this, except for the
+declaration commands listed above, when in POSIX mode.
+
+
+File: bash.info,  Node: Shell Parameter Expansion,  Next: Command Substitution,  Prev: Tilde Expansion,  Up: Shell Expansions
+
+3.5.3 Shell Parameter Expansion
+-------------------------------
+
+The '$' character introduces parameter expansion, command substitution,
+or arithmetic expansion.  The parameter name or symbol to be expanded
+may be enclosed in braces, which are optional but serve to protect the
+variable to be expanded from characters immediately following it which
+could be interpreted as part of the name.
+
+   When braces are used, the matching ending brace is the first '}' not
+escaped by a backslash or within a quoted string, and not within an
+embedded arithmetic expansion, command substitution, or parameter
+expansion.
+
+   The basic form of parameter expansion is ${PARAMETER}.  The value of
+PARAMETER is substituted.  The PARAMETER is a shell parameter as
+described above (*note Shell Parameters::) or an array reference (*note
+Arrays::).  The braces are required when PARAMETER is a positional
+parameter with more than one digit, or when PARAMETER is followed by a
+character that is not to be interpreted as part of its name.
+
+   If the first character of PARAMETER is an exclamation point (!), and
+PARAMETER is not a nameref, it introduces a level of indirection.  Bash
+uses the value formed by expanding the rest of PARAMETER as the new
+PARAMETER; this is then expanded and that value is used in the rest of
+the expansion, rather than the expansion of the original PARAMETER.
+This is known as 'indirect expansion'.  The value is subject to tilde
+expansion, parameter expansion, command substitution, and arithmetic
+expansion.  If PARAMETER is a nameref, this expands to the name of the
+variable referenced by PARAMETER instead of performing the complete
+indirect expansion.  The exceptions to this are the expansions of
+${!PREFIX*} and ${!NAME[@]} described below.  The exclamation point must
+immediately follow the left brace in order to introduce indirection.
+
+   In each of the cases below, WORD is subject to tilde expansion,
+parameter expansion, command substitution, and arithmetic expansion.
+
+   When not performing substring expansion, using the form described
+below (e.g., ':-'), Bash tests for a parameter that is unset or null.
+Omitting the colon results in a test only for a parameter that is unset.
+Put another way, if the colon is included, the operator tests for both
+PARAMETER's existence and that its value is not null; if the colon is
+omitted, the operator tests only for existence.
+
+'${PARAMETER:-WORD}'
+     If PARAMETER is unset or null, the expansion of WORD is
+     substituted.  Otherwise, the value of PARAMETER is substituted.
+
+          $ v=123
+          $ echo ${v-unset}
+          123
+
+'${PARAMETER:=WORD}'
+     If PARAMETER is unset or null, the expansion of WORD is assigned to
+     PARAMETER.  The value of PARAMETER is then substituted.  Positional
+     parameters and special parameters may not be assigned to in this
+     way.
+
+          $ var=
+          $ : ${var:=DEFAULT}
+          $ echo $var
+          DEFAULT
+
+'${PARAMETER:?WORD}'
+     If PARAMETER is null or unset, the expansion of WORD (or a message
+     to that effect if WORD is not present) is written to the standard
+     error and the shell, if it is not interactive, exits.  Otherwise,
+     the value of PARAMETER is substituted.
+
+          $ var=
+          $ : ${var:?var is unset or null}
+          bash: var: var is unset or null
+
+'${PARAMETER:+WORD}'
+     If PARAMETER is null or unset, nothing is substituted, otherwise
+     the expansion of WORD is substituted.
+
+          $ var=123
+          $ echo ${var:+var is set and not null}
+          var is set and not null
+
+'${PARAMETER:OFFSET}'
+'${PARAMETER:OFFSET:LENGTH}'
+     This is referred to as Substring Expansion.  It expands to up to
+     LENGTH characters of the value of PARAMETER starting at the
+     character specified by OFFSET.  If PARAMETER is '@' or '*', an
+     indexed array subscripted by '@' or '*', or an associative array
+     name, the results differ as described below.  If LENGTH is omitted,
+     it expands to the substring of the value of PARAMETER starting at
+     the character specified by OFFSET and extending to the end of the
+     value.  LENGTH and OFFSET are arithmetic expressions (*note Shell
+     Arithmetic::).
+
+     If OFFSET evaluates to a number less than zero, the value is used
+     as an offset in characters from the end of the value of PARAMETER.
+     If LENGTH evaluates to a number less than zero, it is interpreted
+     as an offset in characters from the end of the value of PARAMETER
+     rather than a number of characters, and the expansion is the
+     characters between OFFSET and that result.  Note that a negative
+     offset must be separated from the colon by at least one space to
+     avoid being confused with the ':-' expansion.
+
+     Here are some examples illustrating substring expansion on
+     parameters and subscripted arrays:
+
+     $ string=01234567890abcdefgh
+     $ echo ${string:7}
+     7890abcdefgh
+     $ echo ${string:7:0}
+     
+     $ echo ${string:7:2}
+     78
+     $ echo ${string:7:-2}
+     7890abcdef
+     $ echo ${string: -7}
+     bcdefgh
+     $ echo ${string: -7:0}
+     
+     $ echo ${string: -7:2}
+     bc
+     $ echo ${string: -7:-2}
+     bcdef
+     $ set -- 01234567890abcdefgh
+     $ echo ${1:7}
+     7890abcdefgh
+     $ echo ${1:7:0}
+     
+     $ echo ${1:7:2}
+     78
+     $ echo ${1:7:-2}
+     7890abcdef
+     $ echo ${1: -7}
+     bcdefgh
+     $ echo ${1: -7:0}
+     
+     $ echo ${1: -7:2}
+     bc
+     $ echo ${1: -7:-2}
+     bcdef
+     $ array[0]=01234567890abcdefgh
+     $ echo ${array[0]:7}
+     7890abcdefgh
+     $ echo ${array[0]:7:0}
+     
+     $ echo ${array[0]:7:2}
+     78
+     $ echo ${array[0]:7:-2}
+     7890abcdef
+     $ echo ${array[0]: -7}
+     bcdefgh
+     $ echo ${array[0]: -7:0}
+     
+     $ echo ${array[0]: -7:2}
+     bc
+     $ echo ${array[0]: -7:-2}
+     bcdef
+
+     If PARAMETER is '@' or '*', the result is LENGTH positional
+     parameters beginning at OFFSET.  A negative OFFSET is taken
+     relative to one greater than the greatest positional parameter, so
+     an offset of -1 evaluates to the last positional parameter.  It is
+     an expansion error if LENGTH evaluates to a number less than zero.
+
+     The following examples illustrate substring expansion using
+     positional parameters:
+
+     $ set -- 1 2 3 4 5 6 7 8 9 0 a b c d e f g h
+     $ echo ${@:7}
+     7 8 9 0 a b c d e f g h
+     $ echo ${@:7:0}
+     
+     $ echo ${@:7:2}
+     7 8
+     $ echo ${@:7:-2}
+     bash: -2: substring expression < 0
+     $ echo ${@: -7:2}
+     b c
+     $ echo ${@:0}
+     ./bash 1 2 3 4 5 6 7 8 9 0 a b c d e f g h
+     $ echo ${@:0:2}
+     ./bash 1
+     $ echo ${@: -7:0}
+     
+
+     If PARAMETER is an indexed array name subscripted by '@' or '*',
+     the result is the LENGTH members of the array beginning with
+     '${PARAMETER[OFFSET]}'.  A negative OFFSET is taken relative to one
+     greater than the maximum index of the specified array.  It is an
+     expansion error if LENGTH evaluates to a number less than zero.
+
+     These examples show how you can use substring expansion with
+     indexed arrays:
+
+     $ array=(0 1 2 3 4 5 6 7 8 9 0 a b c d e f g h)
+     $ echo ${array[@]:7}
+     7 8 9 0 a b c d e f g h
+     $ echo ${array[@]:7:2}
+     7 8
+     $ echo ${array[@]: -7:2}
+     b c
+     $ echo ${array[@]: -7:-2}
+     bash: -2: substring expression < 0
+     $ echo ${array[@]:0}
+     0 1 2 3 4 5 6 7 8 9 0 a b c d e f g h
+     $ echo ${array[@]:0:2}
+     0 1
+     $ echo ${array[@]: -7:0}
+     
+
+     Substring expansion applied to an associative array produces
+     undefined results.
+
+     Substring indexing is zero-based unless the positional parameters
+     are used, in which case the indexing starts at 1 by default.  If
+     OFFSET is 0, and the positional parameters are used, '$0' is
+     prefixed to the list.
+
+'${!PREFIX*}'
+'${!PREFIX@}'
+     Expands to the names of variables whose names begin with PREFIX,
+     separated by the first character of the 'IFS' special variable.
+     When '@' is used and the expansion appears within double quotes,
+     each variable name expands to a separate word.
+
+'${!NAME[@]}'
+'${!NAME[*]}'
+     If NAME is an array variable, expands to the list of array indices
+     (keys) assigned in NAME.  If NAME is not an array, expands to 0 if
+     NAME is set and null otherwise.  When '@' is used and the expansion
+     appears within double quotes, each key expands to a separate word.
+
+'${#PARAMETER}'
+     The length in characters of the expanded value of PARAMETER is
+     substituted.  If PARAMETER is '*' or '@', the value substituted is
+     the number of positional parameters.  If PARAMETER is an array name
+     subscripted by '*' or '@', the value substituted is the number of
+     elements in the array.  If PARAMETER is an indexed array name
+     subscripted by a negative number, that number is interpreted as
+     relative to one greater than the maximum index of PARAMETER, so
+     negative indices count back from the end of the array, and an index
+     of -1 references the last element.
+
+'${PARAMETER#WORD}'
+'${PARAMETER##WORD}'
+     The WORD is expanded to produce a pattern and matched according to
+     the rules described below (*note Pattern Matching::).  If the
+     pattern matches the beginning of the expanded value of PARAMETER,
+     then the result of the expansion is the expanded value of PARAMETER
+     with the shortest matching pattern (the '#' case) or the longest
+     matching pattern (the '##' case) deleted.  If PARAMETER is '@' or
+     '*', the pattern removal operation is applied to each positional
+     parameter in turn, and the expansion is the resultant list.  If
+     PARAMETER is an array variable subscripted with '@' or '*', the
+     pattern removal operation is applied to each member of the array in
+     turn, and the expansion is the resultant list.
+
+'${PARAMETER%WORD}'
+'${PARAMETER%%WORD}'
+     The WORD is expanded to produce a pattern and matched according to
+     the rules described below (*note Pattern Matching::).  If the
+     pattern matches a trailing portion of the expanded value of
+     PARAMETER, then the result of the expansion is the value of
+     PARAMETER with the shortest matching pattern (the '%' case) or the
+     longest matching pattern (the '%%' case) deleted.  If PARAMETER is
+     '@' or '*', the pattern removal operation is applied to each
+     positional parameter in turn, and the expansion is the resultant
+     list.  If PARAMETER is an array variable subscripted with '@' or
+     '*', the pattern removal operation is applied to each member of the
+     array in turn, and the expansion is the resultant list.
+
+'${PARAMETER/PATTERN/STRING}'
+'${PARAMETER//PATTERN/STRING}'
+'${PARAMETER/#PATTERN/STRING}'
+'${PARAMETER/%PATTERN/STRING}'
+     The PATTERN is expanded to produce a pattern just as in filename
+     expansion.  PARAMETER is expanded and the longest match of PATTERN
+     against its value is replaced with STRING.  STRING undergoes tilde
+     expansion, parameter and variable expansion, arithmetic expansion,
+     command and process substitution, and quote removal.  The match is
+     performed according to the rules described below (*note Pattern
+     Matching::).
+
+     In the first form above, only the first match is replaced.  If
+     there are two slashes separating PARAMETER and PATTERN (the second
+     form above), all matches of PATTERN are replaced with STRING.  If
+     PATTERN is preceded by '#' (the third form above), it must match at
+     the beginning of the expanded value of PARAMETER.  If PATTERN is
+     preceded by '%' (the fourth form above), it must match at the end
+     of the expanded value of PARAMETER.  If the expansion of STRING is
+     null, matches of PATTERN are deleted.  If STRING is null, matches
+     of PATTERN are deleted and the '/' following PATTERN may be
+     omitted.
+
+     If the 'patsub_replacement' shell option is enabled using 'shopt',
+     any unquoted instances of '&' in STRING are replaced with the
+     matching portion of PATTERN.  This is intended to duplicate a
+     common 'sed' idiom.
+
+     Quoting any part of STRING inhibits replacement in the expansion of
+     the quoted portion, including replacement strings stored in shell
+     variables.  Backslash will escape '&' in STRING; the backslash is
+     removed in order to permit a literal '&' in the replacement string.
+     Users should take care if STRING is double-quoted to avoid unwanted
+     interactions between the backslash and double-quoting, since
+     backslash has special meaning within double quotes.  Pattern
+     substitution performs the check for unquoted '&' after expanding
+     STRING, so users should ensure to properly quote any occurrences of
+     '&' they want to be taken literally in the replacement and ensure
+     any instances of '&' they want to be replaced are unquoted.
+
+     For instance,
+
+          var=abcdef
+          rep='& '
+          echo ${var/abc/& }
+          echo "${var/abc/& }"
+          echo ${var/abc/$rep}
+          echo "${var/abc/$rep}"
+
+     will display four lines of "abc def", while
+
+          var=abcdef
+          rep='& '
+          echo ${var/abc/\& }
+          echo "${var/abc/\& }"
+          echo ${var/abc/"& "}
+          echo ${var/abc/"$rep"}
+
+     will display four lines of "& def".  Like the pattern removal
+     operators, double quotes surrounding the replacement string quote
+     the expanded characters, while double quotes enclosing the entire
+     parameter substitution do not, since the expansion is performed in
+     a context that doesn't take any enclosing double quotes into
+     account.
+
+     Since backslash can escape '&', it can also escape a backslash in
+     the replacement string.  This means that '\\' will insert a literal
+     backslash into the replacement, so these two 'echo' commands
+
+          var=abcdef
+          rep='\\&xyz'
+          echo ${var/abc/\\&xyz}
+          echo ${var/abc/$rep}
+
+     will both output '\abcxyzdef'.
+
+     It should rarely be necessary to enclose only STRING in double
+     quotes.
+
+     If the 'nocasematch' shell option (see the description of 'shopt'
+     in *note The Shopt Builtin::) is enabled, the match is performed
+     without regard to the case of alphabetic characters.  If PARAMETER
+     is '@' or '*', the substitution operation is applied to each
+     positional parameter in turn, and the expansion is the resultant
+     list.  If PARAMETER is an array variable subscripted with '@' or
+     '*', the substitution operation is applied to each member of the
+     array in turn, and the expansion is the resultant list.
+
+'${PARAMETER^PATTERN}'
+'${PARAMETER^^PATTERN}'
+'${PARAMETER,PATTERN}'
+'${PARAMETER,,PATTERN}'
+     This expansion modifies the case of alphabetic characters in
+     PARAMETER.  The PATTERN is expanded to produce a pattern just as in
+     filename expansion.  Each character in the expanded value of
+     PARAMETER is tested against PATTERN, and, if it matches the
+     pattern, its case is converted.  The pattern should not attempt to
+     match more than one character.
+
+     The '^' operator converts lowercase letters matching PATTERN to
+     uppercase; the ',' operator converts matching uppercase letters to
+     lowercase.  The '^^' and ',,' expansions convert each matched
+     character in the expanded value; the '^' and ',' expansions match
+     and convert only the first character in the expanded value.  If
+     PATTERN is omitted, it is treated like a '?', which matches every
+     character.
+
+     If PARAMETER is '@' or '*', the case modification operation is
+     applied to each positional parameter in turn, and the expansion is
+     the resultant list.  If PARAMETER is an array variable subscripted
+     with '@' or '*', the case modification operation is applied to each
+     member of the array in turn, and the expansion is the resultant
+     list.
+
+'${PARAMETER@OPERATOR}'
+     The expansion is either a transformation of the value of PARAMETER
+     or information about PARAMETER itself, depending on the value of
+     OPERATOR.  Each OPERATOR is a single letter:
+
+     'U'
+          The expansion is a string that is the value of PARAMETER with
+          lowercase alphabetic characters converted to uppercase.
+     'u'
+          The expansion is a string that is the value of PARAMETER with
+          the first character converted to uppercase, if it is
+          alphabetic.
+     'L'
+          The expansion is a string that is the value of PARAMETER with
+          uppercase alphabetic characters converted to lowercase.
+     'Q'
+          The expansion is a string that is the value of PARAMETER
+          quoted in a format that can be reused as input.
+     'E'
+          The expansion is a string that is the value of PARAMETER with
+          backslash escape sequences expanded as with the '$'...''
+          quoting mechanism.
+     'P'
+          The expansion is a string that is the result of expanding the
+          value of PARAMETER as if it were a prompt string (*note
+          Controlling the Prompt::).
+     'A'
+          The expansion is a string in the form of an assignment
+          statement or 'declare' command that, if evaluated, will
+          recreate PARAMETER with its attributes and value.
+     'K'
+          Produces a possibly-quoted version of the value of PARAMETER,
+          except that it prints the values of indexed and associative
+          arrays as a sequence of quoted key-value pairs (*note
+          Arrays::).
+     'a'
+          The expansion is a string consisting of flag values
+          representing PARAMETER's attributes.
+     'k'
+          Like the 'K' transformation, but expands the keys and values
+          of indexed and associative arrays to separate words after word
+          splitting.
+
+     If PARAMETER is '@' or '*', the operation is applied to each
+     positional parameter in turn, and the expansion is the resultant
+     list.  If PARAMETER is an array variable subscripted with '@' or
+     '*', the operation is applied to each member of the array in turn,
+     and the expansion is the resultant list.
+
+     The result of the expansion is subject to word splitting and
+     filename expansion as described below.

+
+3.5.4 Command Substitution
+--------------------------
+
+Command substitution allows the output of a command to replace the
+command itself.  Command substitution occurs when a command is enclosed
+as follows:
+     $(COMMAND)
+or
+     `COMMAND`
+
+Bash performs the expansion by executing COMMAND in a subshell
+environment and replacing the command substitution with the standard
+output of the command, with any trailing newlines deleted.  Embedded
+newlines are not deleted, but they may be removed during word splitting.
+The command substitution '$(cat FILE)' can be replaced by the equivalent
+but faster '$(< FILE)'.
+
+   When the old-style backquote form of substitution is used, backslash
+retains its literal meaning except when followed by '$', '`', or '\'.
+The first backquote not preceded by a backslash terminates the command
+substitution.  When using the '$(COMMAND)' form, all characters between
+the parentheses make up the command; none are treated specially.
+
+   Command substitutions may be nested.  To nest when using the
+backquoted form, escape the inner backquotes with backslashes.
+
+   If the substitution appears within double quotes, word splitting and
+filename expansion are not performed on the results.
+
+
+File: bash.info,  Node: Arithmetic Expansion,  Next: Process Substitution,  Prev: Command Substitution,  Up: Shell Expansions
+
+3.5.5 Arithmetic Expansion
+--------------------------
+
+Arithmetic expansion allows the evaluation of an arithmetic expression
+and the substitution of the result.  The format for arithmetic expansion
+is:
+
+     $(( EXPRESSION ))
+
+   The EXPRESSION undergoes the same expansions as if it were within
+double quotes, but double quote characters in EXPRESSION are not treated
+specially and are removed.  All tokens in the expression undergo
+parameter and variable expansion, command substitution, and quote
+removal.  The result is treated as the arithmetic expression to be
+evaluated.  Arithmetic expansions may be nested.
+
+   The evaluation is performed according to the rules listed below
+(*note Shell Arithmetic::).  If the expression is invalid, Bash prints a
+message indicating failure to the standard error and no substitution
+occurs.
+
+
+File: bash.info,  Node: Process Substitution,  Next: Word Splitting,  Prev: Arithmetic Expansion,  Up: Shell Expansions
+
+3.5.6 Process Substitution
+--------------------------
+
+Process substitution allows a process's input or output to be referred
+to using a filename.  It takes the form of
+     <(LIST)
+or
+     >(LIST)
+The process LIST is run asynchronously, and its input or output appears
+as a filename.  This filename is passed as an argument to the current
+command as the result of the expansion.  If the '>(LIST)' form is used,
+writing to the file will provide input for LIST.  If the '<(LIST)' form
+is used, the file passed as an argument should be read to obtain the
+output of LIST.  Note that no space may appear between the '<' or '>'
+and the left parenthesis, otherwise the construct would be interpreted
+as a redirection.  Process substitution is supported on systems that
+support named pipes (FIFOs) or the '/dev/fd' method of naming open
+files.
+
+   When available, process substitution is performed simultaneously with
+parameter and variable expansion, command substitution, and arithmetic
+expansion.
+
+
+File: bash.info,  Node: Word Splitting,  Next: Filename Expansion,  Prev: Process Substitution,  Up: Shell Expansions
+
+3.5.7 Word Splitting
+--------------------
+
+The shell scans the results of parameter expansion, command
+substitution, and arithmetic expansion that did not occur within double
+quotes for word splitting.
+
+   The shell treats each character of '$IFS' as a delimiter, and splits
+the results of the other expansions into words using these characters as
+field terminators.  If 'IFS' is unset, or its value is exactly
+'<space><tab><newline>', the default, then sequences of ' <space>',
+'<tab>', and '<newline>' at the beginning and end of the results of the
+previous expansions are ignored, and any sequence of 'IFS' characters
+not at the beginning or end serves to delimit words.  If 'IFS' has a
+value other than the default, then sequences of the whitespace
+characters 'space', 'tab', and 'newline' are ignored at the beginning
+and end of the word, as long as the whitespace character is in the value
+of 'IFS' (an 'IFS' whitespace character).  Any character in 'IFS' that
+is not 'IFS' whitespace, along with any adjacent 'IFS' whitespace
+characters, delimits a field.  A sequence of 'IFS' whitespace characters
+is also treated as a delimiter.  If the value of 'IFS' is null, no word
+splitting occurs.
+
+   Explicit null arguments ('""' or '''') are retained and passed to
+commands as empty strings.  Unquoted implicit null arguments, resulting
+from the expansion of parameters that have no values, are removed.  If a
+parameter with no value is expanded within double quotes, a null
+argument results and is retained and passed to a command as an empty
+string.  When a quoted null argument appears as part of a word whose
+expansion is non-null, the null argument is removed.  That is, the word
+'-d''' becomes '-d' after word splitting and null argument removal.
+
+   Note that if no expansion occurs, no splitting is performed.

+
+3.5.8 Filename Expansion
+------------------------
+
+* Menu:
+
+* Pattern Matching::	How the shell matches patterns.
+
+After word splitting, unless the '-f' option has been set (*note The Set
+Builtin::), Bash scans each word for the characters '*', '?', and '['.
+If one of these characters appears, and is not quoted, then the word is
+regarded as a PATTERN, and replaced with an alphabetically sorted list
+of filenames matching the pattern (*note Pattern Matching::).  If no
+matching filenames are found, and the shell option 'nullglob' is
+disabled, the word is left unchanged.  If the 'nullglob' option is set,
+and no matches are found, the word is removed.  If the 'failglob' shell
+option is set, and no matches are found, an error message is printed and
+the command is not executed.  If the shell option 'nocaseglob' is
+enabled, the match is performed without regard to the case of alphabetic
+characters.
+
+   When a pattern is used for filename expansion, the character '.' at
+the start of a filename or immediately following a slash must be matched
+explicitly, unless the shell option 'dotglob' is set.  In order to match
+the filenames '.' and '..', the pattern must begin with '.' (for
+example, '.?'), even if 'dotglob' is set.  If the 'globskipdots' shell
+option is enabled, the filenames '.' and '..' are never matched, even if
+the pattern begins with a '.'.  When not matching filenames, the '.'
+character is not treated specially.
+
+   When matching a filename, the slash character must always be matched
+explicitly by a slash in the pattern, but in other matching contexts it
+can be matched by a special pattern character as described below (*note
+Pattern Matching::).
+
+   See the description of 'shopt' in *note The Shopt Builtin::, for a
+description of the 'nocaseglob', 'nullglob', 'globskipdots', 'failglob',
+and 'dotglob' options.
+
+   The 'GLOBIGNORE' shell variable may be used to restrict the set of
+file names matching a pattern.  If 'GLOBIGNORE' is set, each matching
+file name that also matches one of the patterns in 'GLOBIGNORE' is
+removed from the list of matches.  If the 'nocaseglob' option is set,
+the matching against the patterns in 'GLOBIGNORE' is performed without
+regard to case.  The filenames '.' and '..' are always ignored when
+'GLOBIGNORE' is set and not null.  However, setting 'GLOBIGNORE' to a
+non-null value has the effect of enabling the 'dotglob' shell option, so
+all other filenames beginning with a '.' will match.  To get the old
+behavior of ignoring filenames beginning with a '.', make '.*' one of
+the patterns in 'GLOBIGNORE'.  The 'dotglob' option is disabled when
+'GLOBIGNORE' is unset.
+
+
+File: bash.info,  Node: Pattern Matching,  Up: Filename Expansion
+
+3.5.8.1 Pattern Matching
+........................
+
+Any character that appears in a pattern, other than the special pattern
+characters described below, matches itself.  The NUL character may not
+occur in a pattern.  A backslash escapes the following character; the
+escaping backslash is discarded when matching.  The special pattern
+characters must be quoted if they are to be matched literally.
+
+   The special pattern characters have the following meanings:
+'*'
+     Matches any string, including the null string.  When the 'globstar'
+     shell option is enabled, and '*' is used in a filename expansion
+     context, two adjacent '*'s used as a single pattern will match all
+     files and zero or more directories and subdirectories.  If followed
+     by a '/', two adjacent '*'s will match only directories and
+     subdirectories.
+'?'
+     Matches any single character.
+'[...]'
+     Matches any one of the enclosed characters.  A pair of characters
+     separated by a hyphen denotes a RANGE EXPRESSION; any character
+     that falls between those two characters, inclusive, using the
+     current locale's collating sequence and character set, is matched.
+     If the first character following the '[' is a '!' or a '^' then any
+     character not enclosed is matched.  A '-' may be matched by
+     including it as the first or last character in the set.  A ']' may
+     be matched by including it as the first character in the set.  The
+     sorting order of characters in range expressions, and the
+     characters included in the range, are determined by the current
+     locale and the values of the 'LC_COLLATE' and 'LC_ALL' shell
+     variables, if set.
+
+     For example, in the default C locale, '[a-dx-z]' is equivalent to
+     '[abcdxyz]'.  Many locales sort characters in dictionary order, and
+     in these locales '[a-dx-z]' is typically not equivalent to
+     '[abcdxyz]'; it might be equivalent to '[aBbCcDdxYyZz]', for
+     example.  To obtain the traditional interpretation of ranges in
+     bracket expressions, you can force the use of the C locale by
+     setting the 'LC_COLLATE' or 'LC_ALL' environment variable to the
+     value 'C', or enable the 'globasciiranges' shell option.
+
+     Within '[' and ']', "character classes" can be specified using the
+     syntax '[:'CLASS':]', where CLASS is one of the following classes
+     defined in the POSIX standard:
+          alnum   alpha   ascii   blank   cntrl   digit   graph   lower
+          print   punct   space   upper   word    xdigit
+     A character class matches any character belonging to that class.
+     The 'word' character class matches letters, digits, and the
+     character '_'.
+
+     Within '[' and ']', an "equivalence class" can be specified using
+     the syntax '[='C'=]', which matches all characters with the same
+     collation weight (as defined by the current locale) as the
+     character C.
+
+     Within '[' and ']', the syntax '[.'SYMBOL'.]' matches the collating
+     symbol SYMBOL.
+
+   If the 'extglob' shell option is enabled using the 'shopt' builtin,
+the shell recognizes several extended pattern matching operators.  In
+the following description, a PATTERN-LIST is a list of one or more
+patterns separated by a '|'.  When matching filenames, the 'dotglob'
+shell option determines the set of filenames that are tested, as
+described above.  Composite patterns may be formed using one or more of
+the following sub-patterns:
+
+'?(PATTERN-LIST)'
+     Matches zero or one occurrence of the given patterns.
+
+'*(PATTERN-LIST)'
+     Matches zero or more occurrences of the given patterns.
+
+'+(PATTERN-LIST)'
+     Matches one or more occurrences of the given patterns.
+
+'@(PATTERN-LIST)'
+     Matches one of the given patterns.
+
+'!(PATTERN-LIST)'
+     Matches anything except one of the given patterns.
+
+   The 'extglob' option changes the behavior of the parser, since the
+parentheses are normally treated as operators with syntactic meaning.
+To ensure that extended matching patterns are parsed correctly, make
+sure that 'extglob' is enabled before parsing constructs containing the
+patterns, including shell functions and command substitutions.
+
+   When matching filenames, the 'dotglob' shell option determines the
+set of filenames that are tested: when 'dotglob' is enabled, the set of
+filenames includes all files beginning with '.', but the filenames '.'
+and '..' must be matched by a pattern or sub-pattern that begins with a
+dot; when it is disabled, the set does not include any filenames
+beginning with "."  unless the pattern or sub-pattern begins with a '.'.
+As above, '.' only has a special meaning when matching filenames.
+
+   Complicated extended pattern matching against long strings is slow,
+especially when the patterns contain alternations and the strings
+contain multiple matches.  Using separate matches against shorter
+strings, or using arrays of strings instead of a single long string, may
+be faster.

+
+3.5.9 Quote Removal
+-------------------
+
+After the preceding expansions, all unquoted occurrences of the
+characters '\', ''', and '"' that did not result from one of the above
+expansions are removed.
+
+
+File: bash.info,  Node: Redirections,  Next: Executing Commands,  Prev: Shell Expansions,  Up: Basic Shell Features
+
+3.6 Redirections
+================
+
+Before a command is executed, its input and output may be "redirected"
+using a special notation interpreted by the shell.  "Redirection" allows
+commands' file handles to be duplicated, opened, closed, made to refer
+to different files, and can change the files the command reads from and
+writes to.  Redirection may also be used to modify file handles in the
+current shell execution environment.  The following redirection
+operators may precede or appear anywhere within a simple command or may
+follow a command.  Redirections are processed in the order they appear,
+from left to right.
+
+   Each redirection that may be preceded by a file descriptor number may
+instead be preceded by a word of the form {VARNAME}.  In this case, for
+each redirection operator except >&- and <&-, the shell will allocate a
+file descriptor greater than 10 and assign it to {VARNAME}.  If >&- or
+<&- is preceded by {VARNAME}, the value of VARNAME defines the file
+descriptor to close.  If {VARNAME} is supplied, the redirection persists
+beyond the scope of the command, allowing the shell programmer to manage
+the file descriptor's lifetime manually.  The 'varredir_close' shell
+option manages this behavior (*note The Shopt Builtin::).
+
+   In the following descriptions, if the file descriptor number is
+omitted, and the first character of the redirection operator is '<', the
+redirection refers to the standard input (file descriptor 0).  If the
+first character of the redirection operator is '>', the redirection
+refers to the standard output (file descriptor 1).
+
+   The word following the redirection operator in the following
+descriptions, unless otherwise noted, is subjected to brace expansion,
+tilde expansion, parameter expansion, command substitution, arithmetic
+expansion, quote removal, filename expansion, and word splitting.  If it
+expands to more than one word, Bash reports an error.
+
+   Note that the order of redirections is significant.  For example, the
+command
+     ls > DIRLIST 2>&1
+directs both standard output (file descriptor 1) and standard error
+(file descriptor 2) to the file DIRLIST, while the command
+     ls 2>&1 > DIRLIST
+directs only the standard output to file DIRLIST, because the standard
+error was made a copy of the standard output before the standard output
+was redirected to DIRLIST.
+
+   Bash handles several filenames specially when they are used in
+redirections, as described in the following table.  If the operating
+system on which Bash is running provides these special files, bash will
+use them; otherwise it will emulate them internally with the behavior
+described below.
+
+'/dev/fd/FD'
+     If FD is a valid integer, file descriptor FD is duplicated.
+
+'/dev/stdin'
+     File descriptor 0 is duplicated.
+
+'/dev/stdout'
+     File descriptor 1 is duplicated.
+
+'/dev/stderr'
+     File descriptor 2 is duplicated.
+
+'/dev/tcp/HOST/PORT'
+     If HOST is a valid hostname or Internet address, and PORT is an
+     integer port number or service name, Bash attempts to open the
+     corresponding TCP socket.
+
+'/dev/udp/HOST/PORT'
+     If HOST is a valid hostname or Internet address, and PORT is an
+     integer port number or service name, Bash attempts to open the
+     corresponding UDP socket.
+
+   A failure to open or create a file causes the redirection to fail.
+
+   Redirections using file descriptors greater than 9 should be used
+with care, as they may conflict with file descriptors the shell uses
+internally.
+
+3.6.1 Redirecting Input
+-----------------------
+
+Redirection of input causes the file whose name results from the
+expansion of WORD to be opened for reading on file descriptor 'n', or
+the standard input (file descriptor 0) if 'n' is not specified.
+
+   The general format for redirecting input is:
+     [N]<WORD
+
+3.6.2 Redirecting Output
+------------------------
+
+Redirection of output causes the file whose name results from the
+expansion of WORD to be opened for writing on file descriptor N, or the
+standard output (file descriptor 1) if N is not specified.  If the file
+does not exist it is created; if it does exist it is truncated to zero
+size.
+
+   The general format for redirecting output is:
+     [N]>[|]WORD
+
+   If the redirection operator is '>', and the 'noclobber' option to the
+'set' builtin has been enabled, the redirection will fail if the file
+whose name results from the expansion of WORD exists and is a regular
+file.  If the redirection operator is '>|', or the redirection operator
+is '>' and the 'noclobber' option is not enabled, the redirection is
+attempted even if the file named by WORD exists.
+
+3.6.3 Appending Redirected Output
+---------------------------------
+
+Redirection of output in this fashion causes the file whose name results
+from the expansion of WORD to be opened for appending on file descriptor
+N, or the standard output (file descriptor 1) if N is not specified.  If
+the file does not exist it is created.
+
+   The general format for appending output is:
+     [N]>>WORD
+
+3.6.4 Redirecting Standard Output and Standard Error
+----------------------------------------------------
+
+This construct allows both the standard output (file descriptor 1) and
+the standard error output (file descriptor 2) to be redirected to the
+file whose name is the expansion of WORD.
+
+   There are two formats for redirecting standard output and standard
+error:
+     &>WORD
+and
+     >&WORD
+Of the two forms, the first is preferred.  This is semantically
+equivalent to
+     >WORD 2>&1
+   When using the second form, WORD may not expand to a number or '-'.
+If it does, other redirection operators apply (see Duplicating File
+Descriptors below) for compatibility reasons.
+
+3.6.5 Appending Standard Output and Standard Error
+--------------------------------------------------
+
+This construct allows both the standard output (file descriptor 1) and
+the standard error output (file descriptor 2) to be appended to the file
+whose name is the expansion of WORD.
+
+   The format for appending standard output and standard error is:
+     &>>WORD
+This is semantically equivalent to
+     >>WORD 2>&1
+   (see Duplicating File Descriptors below).
+
+3.6.6 Here Documents
+--------------------
+
+This type of redirection instructs the shell to read input from the
+current source until a line containing only WORD (with no trailing
+blanks) is seen.  All of the lines read up to that point are then used
+as the standard input (or file descriptor N if N is specified) for a
+command.
+
+   The format of here-documents is:
+     [N]<<[-]WORD
+             HERE-DOCUMENT
+     DELIMITER
+
+   No parameter and variable expansion, command substitution, arithmetic
+expansion, or filename expansion is performed on WORD.  If any part of
+WORD is quoted, the DELIMITER is the result of quote removal on WORD,
+and the lines in the here-document are not expanded.  If WORD is
+unquoted, all lines of the here-document are subjected to parameter
+expansion, command substitution, and arithmetic expansion, the character
+sequence '\newline' is ignored, and '\' must be used to quote the
+characters '\', '$', and '`'.
+
+   If the redirection operator is '<<-', then all leading tab characters
+are stripped from input lines and the line containing DELIMITER.  This
+allows here-documents within shell scripts to be indented in a natural
+fashion.
+
+3.6.7 Here Strings
+------------------
+
+A variant of here documents, the format is:
+     [N]<<< WORD
+
+   The WORD undergoes tilde expansion, parameter and variable expansion,
+command substitution, arithmetic expansion, and quote removal.  Filename
+expansion and word splitting are not performed.  The result is supplied
+as a single string, with a newline appended, to the command on its
+standard input (or file descriptor N if N is specified).
+
+3.6.8 Duplicating File Descriptors
+----------------------------------
+
+The redirection operator
+     [N]<&WORD
+is used to duplicate input file descriptors.  If WORD expands to one or
+more digits, the file descriptor denoted by N is made to be a copy of
+that file descriptor.  If the digits in WORD do not specify a file
+descriptor open for input, a redirection error occurs.  If WORD
+evaluates to '-', file descriptor N is closed.  If N is not specified,
+the standard input (file descriptor 0) is used.
+
+   The operator
+     [N]>&WORD
+is used similarly to duplicate output file descriptors.  If N is not
+specified, the standard output (file descriptor 1) is used.  If the
+digits in WORD do not specify a file descriptor open for output, a
+redirection error occurs.  If WORD evaluates to '-', file descriptor N
+is closed.  As a special case, if N is omitted, and WORD does not expand
+to one or more digits or '-', the standard output and standard error are
+redirected as described previously.
+
+3.6.9 Moving File Descriptors
+-----------------------------
+
+The redirection operator
+     [N]<&DIGIT-
+moves the file descriptor DIGIT to file descriptor N, or the standard
+input (file descriptor 0) if N is not specified.  DIGIT is closed after
+being duplicated to N.
+
+   Similarly, the redirection operator
+     [N]>&DIGIT-
+moves the file descriptor DIGIT to file descriptor N, or the standard
+output (file descriptor 1) if N is not specified.
+
+3.6.10 Opening File Descriptors for Reading and Writing
+-------------------------------------------------------
+
+The redirection operator
+     [N]<>WORD
+causes the file whose name is the expansion of WORD to be opened for
+both reading and writing on file descriptor N, or on file descriptor 0
+if N is not specified.  If the file does not exist, it is created.

+
+3.7.1 Simple Command Expansion
+------------------------------
+
+When a simple command is executed, the shell performs the following
+expansions, assignments, and redirections, from left to right, in the
+following order.
+
+  1. The words that the parser has marked as variable assignments (those
+     preceding the command name) and redirections are saved for later
+     processing.
+
+  2. The words that are not variable assignments or redirections are
+     expanded (*note Shell Expansions::).  If any words remain after
+     expansion, the first word is taken to be the name of the command
+     and the remaining words are the arguments.
+
+  3. Redirections are performed as described above (*note
+     Redirections::).
+
+  4. The text after the '=' in each variable assignment undergoes tilde
+     expansion, parameter expansion, command substitution, arithmetic
+     expansion, and quote removal before being assigned to the variable.
+
+   If no command name results, the variable assignments affect the
+current shell environment.  In the case of such a command (one that
+consists only of assignment statements and redirections), assignment
+statements are performed before redirections.  Otherwise, the variables
+are added to the environment of the executed command and do not affect
+the current shell environment.  If any of the assignments attempts to
+assign a value to a readonly variable, an error occurs, and the command
+exits with a non-zero status.
+
+   If no command name results, redirections are performed, but do not
+affect the current shell environment.  A redirection error causes the
+command to exit with a non-zero status.
+
+   If there is a command name left after expansion, execution proceeds
+as described below.  Otherwise, the command exits.  If one of the
+expansions contained a command substitution, the exit status of the
+command is the exit status of the last command substitution performed.
+If there were no command substitutions, the command exits with a status
+of zero.
+
+
+File: bash.info,  Node: Command Search and Execution,  Next: Command Execution Environment,  Prev: Simple Command Expansion,  Up: Executing Commands
+
+3.7.2 Command Search and Execution
+----------------------------------
+
+After a command has been split into words, if it results in a simple
+command and an optional list of arguments, the following actions are
+taken.
+
+  1. If the command name contains no slashes, the shell attempts to
+     locate it.  If there exists a shell function by that name, that
+     function is invoked as described in *note Shell Functions::.
+
+  2. If the name does not match a function, the shell searches for it in
+     the list of shell builtins.  If a match is found, that builtin is
+     invoked.
+
+  3. If the name is neither a shell function nor a builtin, and contains
+     no slashes, Bash searches each element of '$PATH' for a directory
+     containing an executable file by that name.  Bash uses a hash table
+     to remember the full pathnames of executable files to avoid
+     multiple 'PATH' searches (see the description of 'hash' in *note
+     Bourne Shell Builtins::).  A full search of the directories in
+     '$PATH' is performed only if the command is not found in the hash
+     table.  If the search is unsuccessful, the shell searches for a
+     defined shell function named 'command_not_found_handle'.  If that
+     function exists, it is invoked in a separate execution environment
+     with the original command and the original command's arguments as
+     its arguments, and the function's exit status becomes the exit
+     status of that subshell.  If that function is not defined, the
+     shell prints an error message and returns an exit status of 127.
+
+  4. If the search is successful, or if the command name contains one or
+     more slashes, the shell executes the named program in a separate
+     execution environment.  Argument 0 is set to the name given, and
+     the remaining arguments to the command are set to the arguments
+     supplied, if any.
+
+  5. If this execution fails because the file is not in executable
+     format, and the file is not a directory, it is assumed to be a
+     "shell script" and the shell executes it as described in *note
+     Shell Scripts::.
+
+  6. If the command was not begun asynchronously, the shell waits for
+     the command to complete and collects its exit status.

+
+3.7.3 Command Execution Environment
+-----------------------------------
+
+The shell has an "execution environment", which consists of the
+following:
+
+   * open files inherited by the shell at invocation, as modified by
+     redirections supplied to the 'exec' builtin
+
+   * the current working directory as set by 'cd', 'pushd', or 'popd',
+     or inherited by the shell at invocation
+
+   * the file creation mode mask as set by 'umask' or inherited from the
+     shell's parent
+
+   * current traps set by 'trap'
+
+   * shell parameters that are set by variable assignment or with 'set'
+     or inherited from the shell's parent in the environment
+
+   * shell functions defined during execution or inherited from the
+     shell's parent in the environment
+
+   * options enabled at invocation (either by default or with
+     command-line arguments) or by 'set'
+
+   * options enabled by 'shopt' (*note The Shopt Builtin::)
+
+   * shell aliases defined with 'alias' (*note Aliases::)
+
+   * various process IDs, including those of background jobs (*note
+     Lists::), the value of '$$', and the value of '$PPID'
+
+   When a simple command other than a builtin or shell function is to be
+executed, it is invoked in a separate execution environment that
+consists of the following.  Unless otherwise noted, the values are
+inherited from the shell.
+
+   * the shell's open files, plus any modifications and additions
+     specified by redirections to the command
+
+   * the current working directory
+
+   * the file creation mode mask
+
+   * shell variables and functions marked for export, along with
+     variables exported for the command, passed in the environment
+     (*note Environment::)
+
+   * traps caught by the shell are reset to the values inherited from
+     the shell's parent, and traps ignored by the shell are ignored
+
+   A command invoked in this separate environment cannot affect the
+shell's execution environment.
+
+   A "subshell" is a copy of the shell process.
+
+   Command substitution, commands grouped with parentheses, and
+asynchronous commands are invoked in a subshell environment that is a
+duplicate of the shell environment, except that traps caught by the
+shell are reset to the values that the shell inherited from its parent
+at invocation.  Builtin commands that are invoked as part of a pipeline
+are also executed in a subshell environment.  Changes made to the
+subshell environment cannot affect the shell's execution environment.
+
+   Subshells spawned to execute command substitutions inherit the value
+of the '-e' option from the parent shell.  When not in POSIX mode, Bash
+clears the '-e' option in such subshells.
+
+   If a command is followed by a '&' and job control is not active, the
+default standard input for the command is the empty file '/dev/null'.
+Otherwise, the invoked command inherits the file descriptors of the
+calling shell as modified by redirections.
+
+
+File: bash.info,  Node: Environment,  Next: Exit Status,  Prev: Command Execution Environment,  Up: Executing Commands
+
+3.7.4 Environment
+-----------------
+
+When a program is invoked it is given an array of strings called the
+"environment".  This is a list of name-value pairs, of the form
+'name=value'.
+
+   Bash provides several ways to manipulate the environment.  On
+invocation, the shell scans its own environment and creates a parameter
+for each name found, automatically marking it for 'export' to child
+processes.  Executed commands inherit the environment.  The 'export' and
+'declare -x' commands allow parameters and functions to be added to and
+deleted from the environment.  If the value of a parameter in the
+environment is modified, the new value becomes part of the environment,
+replacing the old.  The environment inherited by any executed command
+consists of the shell's initial environment, whose values may be
+modified in the shell, less any pairs removed by the 'unset' and 'export
+-n' commands, plus any additions via the 'export' and 'declare -x'
+commands.
+
+   The environment for any simple command or function may be augmented
+temporarily by prefixing it with parameter assignments, as described in
+*note Shell Parameters::.  These assignment statements affect only the
+environment seen by that command.
+
+   If the '-k' option is set (*note The Set Builtin::), then all
+parameter assignments are placed in the environment for a command, not
+just those that precede the command name.
+
+   When Bash invokes an external command, the variable '$_' is set to
+the full pathname of the command and passed to that command in its
+environment.
+
+
+File: bash.info,  Node: Exit Status,  Next: Signals,  Prev: Environment,  Up: Executing Commands
+
+3.7.5 Exit Status
+-----------------
+
+The exit status of an executed command is the value returned by the
+'waitpid' system call or equivalent function.  Exit statuses fall
+between 0 and 255, though, as explained below, the shell may use values
+above 125 specially.  Exit statuses from shell builtins and compound
+commands are also limited to this range.  Under certain circumstances,
+the shell will use special values to indicate specific failure modes.
+
+   For the shell's purposes, a command which exits with a zero exit
+status has succeeded.  A non-zero exit status indicates failure.  This
+seemingly counter-intuitive scheme is used so there is one well-defined
+way to indicate success and a variety of ways to indicate various
+failure modes.  When a command terminates on a fatal signal whose number
+is N, Bash uses the value 128+N as the exit status.
+
+   If a command is not found, the child process created to execute it
+returns a status of 127.  If a command is found but is not executable,
+the return status is 126.
+
+   If a command fails because of an error during expansion or
+redirection, the exit status is greater than zero.
+
+   The exit status is used by the Bash conditional commands (*note
+Conditional Constructs::) and some of the list constructs (*note
+Lists::).
+
+   All of the Bash builtins return an exit status of zero if they
+succeed and a non-zero status on failure, so they may be used by the
+conditional and list constructs.  All builtins return an exit status of
+2 to indicate incorrect usage, generally invalid options or missing
+arguments.
+
+   The exit status of the last command is available in the special
+parameter $?  (*note Special Parameters::).
+
+
+File: bash.info,  Node: Signals,  Prev: Exit Status,  Up: Executing Commands
+
+3.7.6 Signals
+-------------
+
+When Bash is interactive, in the absence of any traps, it ignores
+'SIGTERM' (so that 'kill 0' does not kill an interactive shell), and
+'SIGINT' is caught and handled (so that the 'wait' builtin is
+interruptible).  When Bash receives a 'SIGINT', it breaks out of any
+executing loops.  In all cases, Bash ignores 'SIGQUIT'.  If job control
+is in effect (*note Job Control::), Bash ignores 'SIGTTIN', 'SIGTTOU',
+and 'SIGTSTP'.
+
+   Non-builtin commands started by Bash have signal handlers set to the
+values inherited by the shell from its parent.  When job control is not
+in effect, asynchronous commands ignore 'SIGINT' and 'SIGQUIT' in
+addition to these inherited handlers.  Commands run as a result of
+command substitution ignore the keyboard-generated job control signals
+'SIGTTIN', 'SIGTTOU', and 'SIGTSTP'.
+
+   The shell exits by default upon receipt of a 'SIGHUP'.  Before
+exiting, an interactive shell resends the 'SIGHUP' to all jobs, running
+or stopped.  Stopped jobs are sent 'SIGCONT' to ensure that they receive
+the 'SIGHUP'.  To prevent the shell from sending the 'SIGHUP' signal to
+a particular job, it should be removed from the jobs table with the
+'disown' builtin (*note Job Control Builtins::) or marked to not receive
+'SIGHUP' using 'disown -h'.
+
+   If the 'huponexit' shell option has been set with 'shopt' (*note The
+Shopt Builtin::), Bash sends a 'SIGHUP' to all jobs when an interactive
+login shell exits.
+
+   If Bash is waiting for a command to complete and receives a signal
+for which a trap has been set, the trap will not be executed until the
+command completes.  When Bash is waiting for an asynchronous command via
+the 'wait' builtin, the reception of a signal for which a trap has been
+set will cause the 'wait' builtin to return immediately with an exit
+status greater than 128, immediately after which the trap is executed.
+
+   When job control is not enabled, and Bash is waiting for a foreground
+command to complete, the shell receives keyboard-generated signals such
+as 'SIGINT' (usually generated by '^C') that users commonly intend to
+send to that command.  This happens because the shell and the command
+are in the same process group as the terminal, and '^C' sends 'SIGINT'
+to all processes in that process group.  See *note Job Control::, for a
+more in-depth discussion of process groups.
+
+   When Bash is running without job control enabled and receives
+'SIGINT' while waiting for a foreground command, it waits until that
+foreground command terminates and then decides what to do about the
+'SIGINT':
+
+  1. If the command terminates due to the 'SIGINT', Bash concludes that
+     the user meant to end the entire script, and acts on the 'SIGINT'
+     (e.g., by running a 'SIGINT' trap or exiting itself);
+
+  2. If the pipeline does not terminate due to 'SIGINT', the program
+     handled the 'SIGINT' itself and did not treat it as a fatal signal.
+     In that case, Bash does not treat 'SIGINT' as a fatal signal,
+     either, instead assuming that the 'SIGINT' was used as part of the
+     program's normal operation (e.g., 'emacs' uses it to abort editing
+     commands) or deliberately discarded.  However, Bash will run any
+     trap set on 'SIGINT', as it does with any other trapped signal it
+     receives while it is waiting for the foreground command to
+     complete, for compatibility.

+
+3.8 Shell Scripts
+=================
+
+A shell script is a text file containing shell commands.  When such a
+file is used as the first non-option argument when invoking Bash, and
+neither the '-c' nor '-s' option is supplied (*note Invoking Bash::),
+Bash reads and executes commands from the file, then exits.  This mode
+of operation creates a non-interactive shell.  The shell first searches
+for the file in the current directory, and looks in the directories in
+'$PATH' if not found there.
+
+   When Bash runs a shell script, it sets the special parameter '0' to
+the name of the file, rather than the name of the shell, and the
+positional parameters are set to the remaining arguments, if any are
+given.  If no additional arguments are supplied, the positional
+parameters are unset.
+
+   A shell script may be made executable by using the 'chmod' command to
+turn on the execute bit.  When Bash finds such a file while searching
+the '$PATH' for a command, it creates a new instance of itself to
+execute it.  In other words, executing
+     filename ARGUMENTS
+is equivalent to executing
+     bash filename ARGUMENTS
+
+if 'filename' is an executable shell script.  This subshell
+reinitializes itself, so that the effect is as if a new shell had been
+invoked to interpret the script, with the exception that the locations
+of commands remembered by the parent (see the description of 'hash' in
+*note Bourne Shell Builtins::) are retained by the child.
+
+   Most versions of Unix make this a part of the operating system's
+command execution mechanism.  If the first line of a script begins with
+the two characters '#!', the remainder of the line specifies an
+interpreter for the program and, depending on the operating system, one
+or more optional arguments for that interpreter.  Thus, you can specify
+Bash, 'awk', Perl, or some other interpreter and write the rest of the
+script file in that language.
+
+   The arguments to the interpreter consist of one or more optional
+arguments following the interpreter name on the first line of the script
+file, followed by the name of the script file, followed by the rest of
+the arguments supplied to the script.  The details of how the
+interpreter line is split into an interpreter name and a set of
+arguments vary across systems.  Bash will perform this action on
+operating systems that do not handle it themselves.  Note that some
+older versions of Unix limit the interpreter name and a single argument
+to a maximum of 32 characters, so it's not portable to assume that using
+more than one argument will work.
+
+   Bash scripts often begin with '#! /bin/bash' (assuming that Bash has
+been installed in '/bin'), since this ensures that Bash will be used to
+interpret the script, even if it is executed under another shell.  It's
+a common idiom to use 'env' to find 'bash' even if it's been installed
+in another directory: '#!/usr/bin/env bash' will find the first
+occurrence of 'bash' in '$PATH'.

+4 Shell Builtin Commands

+* Menu:
+
+* Bourne Shell Builtins::	Builtin commands inherited from the Bourne
+				Shell.
+* Bash Builtins::		Table of builtins specific to Bash.
+* Modifying Shell Behavior::	Builtins to modify shell attributes and
+				optional behavior.
+* Special Builtins::		Builtin commands classified specially by
+				POSIX.
+
+Builtin commands are contained within the shell itself.  When the name
+of a builtin command is used as the first word of a simple command
+(*note Simple Commands::), the shell executes the command directly,
+without invoking another program.  Builtin commands are necessary to
+implement functionality impossible or inconvenient to obtain with
+separate utilities.
+
+   This section briefly describes the builtins which Bash inherits from
+the Bourne Shell, as well as the builtin commands which are unique to or
+have been extended in Bash.
+
+   Several builtin commands are described in other chapters: builtin
+commands which provide the Bash interface to the job control facilities
+(*note Job Control Builtins::), the directory stack (*note Directory
+Stack Builtins::), the command history (*note Bash History Builtins::),
+and the programmable completion facilities (*note Programmable
+Completion Builtins::).
+
+   Many of the builtins have been extended by POSIX or Bash.
+
+   Unless otherwise noted, each builtin command documented as accepting
+options preceded by '-' accepts '--' to signify the end of the options.
+The ':', 'true', 'false', and 'test'/'[' builtins do not accept options
+and do not treat '--' specially.  The 'exit', 'logout', 'return',
+'break', 'continue', 'let', and 'shift' builtins accept and process
+arguments beginning with '-' without requiring '--'.  Other builtins
+that accept arguments but are not specified as accepting options
+interpret arguments beginning with '-' as invalid options and require
+'--' to prevent this interpretation.
+
+
+File: bash.info,  Node: Bourne Shell Builtins,  Next: Bash Builtins,  Up: Shell Builtin Commands
+
+4.1 Bourne Shell Builtins
+=========================
+
+The following shell builtin commands are inherited from the Bourne
+Shell.  These commands are implemented as specified by the POSIX
+standard.
+
+': (a colon)'
+          : [ARGUMENTS]
+
+     Do nothing beyond expanding ARGUMENTS and performing redirections.
+     The return status is zero.
+
+'. (a period)'
+          . FILENAME [ARGUMENTS]
+
+     Read and execute commands from the FILENAME argument in the current
+     shell context.  If FILENAME does not contain a slash, the 'PATH'
+     variable is used to find FILENAME, but FILENAME does not need to be
+     executable.  When Bash is not in POSIX mode, it searches the
+     current directory if FILENAME is not found in '$PATH'.  If any
+     ARGUMENTS are supplied, they become the positional parameters when
+     FILENAME is executed.  Otherwise the positional parameters are
+     unchanged.  If the '-T' option is enabled, '.' inherits any trap on
+     'DEBUG'; if it is not, any 'DEBUG' trap string is saved and
+     restored around the call to '.', and '.' unsets the 'DEBUG' trap
+     while it executes.  If '-T' is not set, and the sourced file
+     changes the 'DEBUG' trap, the new value is retained when '.'
+     completes.  The return status is the exit status of the last
+     command executed, or zero if no commands are executed.  If FILENAME
+     is not found, or cannot be read, the return status is non-zero.
+     This builtin is equivalent to 'source'.
+
+'break'
+          break [N]
+
+     Exit from a 'for', 'while', 'until', or 'select' loop.  If N is
+     supplied, the Nth enclosing loop is exited.  N must be greater than
+     or equal to 1.  The return status is zero unless N is not greater
+     than or equal to 1.
+
+'cd'
+          cd [-L|[-P [-e]] [-@] [DIRECTORY]
+
+     Change the current working directory to DIRECTORY.  If DIRECTORY is
+     not supplied, the value of the 'HOME' shell variable is used.  If
+     the shell variable 'CDPATH' exists, it is used as a search path:
+     each directory name in 'CDPATH' is searched for DIRECTORY, with
+     alternative directory names in 'CDPATH' separated by a colon (':').
+     If DIRECTORY begins with a slash, 'CDPATH' is not used.
+
+     The '-P' option means to not follow symbolic links: symbolic links
+     are resolved while 'cd' is traversing DIRECTORY and before
+     processing an instance of '..' in DIRECTORY.
+
+     By default, or when the '-L' option is supplied, symbolic links in
+     DIRECTORY are resolved after 'cd' processes an instance of '..' in
+     DIRECTORY.
+
+     If '..' appears in DIRECTORY, it is processed by removing the
+     immediately preceding pathname component, back to a slash or the
+     beginning of DIRECTORY.
+
+     If the '-e' option is supplied with '-P' and the current working
+     directory cannot be successfully determined after a successful
+     directory change, 'cd' will return an unsuccessful status.
+
+     On systems that support it, the '-@' option presents the extended
+     attributes associated with a file as a directory.
+
+     If DIRECTORY is '-', it is converted to '$OLDPWD' before the
+     directory change is attempted.
+
+     If a non-empty directory name from 'CDPATH' is used, or if '-' is
+     the first argument, and the directory change is successful, the
+     absolute pathname of the new working directory is written to the
+     standard output.
+
+     If the directory change is successful, 'cd' sets the value of the
+     'PWD' environment variable to the new directory name, and sets the
+     'OLDPWD' environment variable to the value of the current working
+     directory before the change.
+
+     The return status is zero if the directory is successfully changed,
+     non-zero otherwise.
+
+'continue'
+          continue [N]
+
+     Resume the next iteration of an enclosing 'for', 'while', 'until',
+     or 'select' loop.  If N is supplied, the execution of the Nth
+     enclosing loop is resumed.  N must be greater than or equal to 1.
+     The return status is zero unless N is not greater than or equal to
+     1.
+
+'eval'
+          eval [ARGUMENTS]
+
+     The arguments are concatenated together into a single command,
+     which is then read and executed, and its exit status returned as
+     the exit status of 'eval'.  If there are no arguments or only empty
+     arguments, the return status is zero.
+
+'exec'
+          exec [-cl] [-a NAME] [COMMAND [ARGUMENTS]]
+
+     If COMMAND is supplied, it replaces the shell without creating a
+     new process.  If the '-l' option is supplied, the shell places a
+     dash at the beginning of the zeroth argument passed to COMMAND.
+     This is what the 'login' program does.  The '-c' option causes
+     COMMAND to be executed with an empty environment.  If '-a' is
+     supplied, the shell passes NAME as the zeroth argument to COMMAND.
+     If COMMAND cannot be executed for some reason, a non-interactive
+     shell exits, unless the 'execfail' shell option is enabled.  In
+     that case, it returns failure.  An interactive shell returns
+     failure if the file cannot be executed.  A subshell exits
+     unconditionally if 'exec' fails.  If no COMMAND is specified,
+     redirections may be used to affect the current shell environment.
+     If there are no redirection errors, the return status is zero;
+     otherwise the return status is non-zero.
+
+'exit'
+          exit [N]
+
+     Exit the shell, returning a status of N to the shell's parent.  If
+     N is omitted, the exit status is that of the last command executed.
+     Any trap on 'EXIT' is executed before the shell terminates.
+
+'export'
+          export [-fn] [-p] [NAME[=VALUE]]
+
+     Mark each NAME to be passed to child processes in the environment.
+     If the '-f' option is supplied, the NAMEs refer to shell functions;
+     otherwise the names refer to shell variables.  The '-n' option
+     means to no longer mark each NAME for export.  If no NAMEs are
+     supplied, or if the '-p' option is given, a list of names of all
+     exported variables is displayed.  The '-p' option displays output
+     in a form that may be reused as input.  If a variable name is
+     followed by =VALUE, the value of the variable is set to VALUE.
+
+     The return status is zero unless an invalid option is supplied, one
+     of the names is not a valid shell variable name, or '-f' is
+     supplied with a name that is not a shell function.
+
+'getopts'
+          getopts OPTSTRING NAME [ARG ...]
+
+     'getopts' is used by shell scripts to parse positional parameters.
+     OPTSTRING contains the option characters to be recognized; if a
+     character is followed by a colon, the option is expected to have an
+     argument, which should be separated from it by whitespace.  The
+     colon (':') and question mark ('?') may not be used as option
+     characters.  Each time it is invoked, 'getopts' places the next
+     option in the shell variable NAME, initializing NAME if it does not
+     exist, and the index of the next argument to be processed into the
+     variable 'OPTIND'.  'OPTIND' is initialized to 1 each time the
+     shell or a shell script is invoked.  When an option requires an
+     argument, 'getopts' places that argument into the variable
+     'OPTARG'.  The shell does not reset 'OPTIND' automatically; it must
+     be manually reset between multiple calls to 'getopts' within the
+     same shell invocation if a new set of parameters is to be used.
+
+     When the end of options is encountered, 'getopts' exits with a
+     return value greater than zero.  'OPTIND' is set to the index of
+     the first non-option argument, and NAME is set to '?'.
+
+     'getopts' normally parses the positional parameters, but if more
+     arguments are supplied as ARG values, 'getopts' parses those
+     instead.
+
+     'getopts' can report errors in two ways.  If the first character of
+     OPTSTRING is a colon, SILENT error reporting is used.  In normal
+     operation, diagnostic messages are printed when invalid options or
+     missing option arguments are encountered.  If the variable 'OPTERR'
+     is set to 0, no error messages will be displayed, even if the first
+     character of 'optstring' is not a colon.
+
+     If an invalid option is seen, 'getopts' places '?' into NAME and,
+     if not silent, prints an error message and unsets 'OPTARG'.  If
+     'getopts' is silent, the option character found is placed in
+     'OPTARG' and no diagnostic message is printed.
+
+     If a required argument is not found, and 'getopts' is not silent, a
+     question mark ('?') is placed in NAME, 'OPTARG' is unset, and a
+     diagnostic message is printed.  If 'getopts' is silent, then a
+     colon (':') is placed in NAME and 'OPTARG' is set to the option
+     character found.
+
+'hash'
+          hash [-r] [-p FILENAME] [-dt] [NAME]
+
+     Each time 'hash' is invoked, it remembers the full pathnames of the
+     commands specified as NAME arguments, so they need not be searched
+     for on subsequent invocations.  The commands are found by searching
+     through the directories listed in '$PATH'.  Any
+     previously-remembered pathname is discarded.  The '-p' option
+     inhibits the path search, and FILENAME is used as the location of
+     NAME.  The '-r' option causes the shell to forget all remembered
+     locations.  The '-d' option causes the shell to forget the
+     remembered location of each NAME.  If the '-t' option is supplied,
+     the full pathname to which each NAME corresponds is printed.  If
+     multiple NAME arguments are supplied with '-t', the NAME is printed
+     before the hashed full pathname.  The '-l' option causes output to
+     be displayed in a format that may be reused as input.  If no
+     arguments are given, or if only '-l' is supplied, information about
+     remembered commands is printed.  The return status is zero unless a
+     NAME is not found or an invalid option is supplied.
+
+'pwd'
+          pwd [-LP]
+
+     Print the absolute pathname of the current working directory.  If
+     the '-P' option is supplied, the pathname printed will not contain
+     symbolic links.  If the '-L' option is supplied, the pathname
+     printed may contain symbolic links.  The return status is zero
+     unless an error is encountered while determining the name of the
+     current directory or an invalid option is supplied.
+
+'readonly'
+          readonly [-aAf] [-p] [NAME[=VALUE]] ...
+
+     Mark each NAME as readonly.  The values of these names may not be
+     changed by subsequent assignment.  If the '-f' option is supplied,
+     each NAME refers to a shell function.  The '-a' option means each
+     NAME refers to an indexed array variable; the '-A' option means
+     each NAME refers to an associative array variable.  If both options
+     are supplied, '-A' takes precedence.  If no NAME arguments are
+     given, or if the '-p' option is supplied, a list of all readonly
+     names is printed.  The other options may be used to restrict the
+     output to a subset of the set of readonly names.  The '-p' option
+     causes output to be displayed in a format that may be reused as
+     input.  If a variable name is followed by =VALUE, the value of the
+     variable is set to VALUE.  The return status is zero unless an
+     invalid option is supplied, one of the NAME arguments is not a
+     valid shell variable or function name, or the '-f' option is
+     supplied with a name that is not a shell function.
+
+'return'
+          return [N]
+
+     Cause a shell function to stop executing and return the value N to
+     its caller.  If N is not supplied, the return value is the exit
+     status of the last command executed in the function.  If 'return'
+     is executed by a trap handler, the last command used to determine
+     the status is the last command executed before the trap handler.
+     If 'return' is executed during a 'DEBUG' trap, the last command
+     used to determine the status is the last command executed by the
+     trap handler before 'return' was invoked.  'return' may also be
+     used to terminate execution of a script being executed with the '.'
+     ('source') builtin, returning either N or the exit status of the
+     last command executed within the script as the exit status of the
+     script.  If N is supplied, the return value is its least
+     significant 8 bits.  Any command associated with the 'RETURN' trap
+     is executed before execution resumes after the function or script.
+     The return status is non-zero if 'return' is supplied a non-numeric
+     argument or is used outside a function and not during the execution
+     of a script by '.' or 'source'.
+
+'shift'
+          shift [N]
+
+     Shift the positional parameters to the left by N.  The positional
+     parameters from N+1 ... '$#' are renamed to '$1' ... '$#'-N.
+     Parameters represented by the numbers '$#' down to '$#'-N+1 are
+     unset.  N must be a non-negative number less than or equal to '$#'.
+     If N is zero or greater than '$#', the positional parameters are
+     not changed.  If N is not supplied, it is assumed to be 1.  The
+     return status is zero unless N is greater than '$#' or less than
+     zero, non-zero otherwise.
+
+'test'
+'['
+          test EXPR
+
+     Evaluate a conditional expression EXPR and return a status of 0
+     (true) or 1 (false).  Each operator and operand must be a separate
+     argument.  Expressions are composed of the primaries described
+     below in *note Bash Conditional Expressions::.  'test' does not
+     accept any options, nor does it accept and ignore an argument of
+     '--' as signifying the end of options.
+
+     When the '[' form is used, the last argument to the command must be
+     a ']'.
+
+     Expressions may be combined using the following operators, listed
+     in decreasing order of precedence.  The evaluation depends on the
+     number of arguments; see below.  Operator precedence is used when
+     there are five or more arguments.
+
+     '! EXPR'
+          True if EXPR is false.
+
+     '( EXPR )'
+          Returns the value of EXPR.  This may be used to override the
+          normal precedence of operators.
+
+     'EXPR1 -a EXPR2'
+          True if both EXPR1 and EXPR2 are true.
+
+     'EXPR1 -o EXPR2'
+          True if either EXPR1 or EXPR2 is true.
+
+     The 'test' and '[' builtins evaluate conditional expressions using
+     a set of rules based on the number of arguments.
+
+     0 arguments
+          The expression is false.
+
+     1 argument
+          The expression is true if, and only if, the argument is not
+          null.
+
+     2 arguments
+          If the first argument is '!', the expression is true if and
+          only if the second argument is null.  If the first argument is
+          one of the unary conditional operators (*note Bash Conditional
+          Expressions::), the expression is true if the unary test is
+          true.  If the first argument is not a valid unary operator,
+          the expression is false.
+
+     3 arguments
+          The following conditions are applied in the order listed.
+
+            1. If the second argument is one of the binary conditional
+               operators (*note Bash Conditional Expressions::), the
+               result of the expression is the result of the binary test
+               using the first and third arguments as operands.  The
+               '-a' and '-o' operators are considered binary operators
+               when there are three arguments.
+            2. If the first argument is '!', the value is the negation
+               of the two-argument test using the second and third
+               arguments.
+            3. If the first argument is exactly '(' and the third
+               argument is exactly ')', the result is the one-argument
+               test of the second argument.
+            4. Otherwise, the expression is false.
+
+     4 arguments
+          The following conditions are applied in the order listed.
+
+            1. If the first argument is '!', the result is the negation
+               of the three-argument expression composed of the
+               remaining arguments.
+            2. If the first argument is exactly '(' and the fourth
+               argument is exactly ')', the result is the two-argument
+               test of the second and third arguments.
+            3. Otherwise, the expression is parsed and evaluated
+               according to precedence using the rules listed above.
+
+     5 or more arguments
+          The expression is parsed and evaluated according to precedence
+          using the rules listed above.
+
+     When used with 'test' or '[', the '<' and '>' operators sort
+     lexicographically using ASCII ordering.
+
+'times'
+          times
+
+     Print out the user and system times used by the shell and its
+     children.  The return status is zero.
+
+'trap'
+          trap [-lp] [ARG] [SIGSPEC ...]
+
+     The commands in ARG are to be read and executed when the shell
+     receives signal SIGSPEC.  If ARG is absent (and there is a single
+     SIGSPEC) or equal to '-', each specified signal's disposition is
+     reset to the value it had when the shell was started.  If ARG is
+     the null string, then the signal specified by each SIGSPEC is
+     ignored by the shell and commands it invokes.  If ARG is not
+     present and '-p' has been supplied, the shell displays the trap
+     commands associated with each SIGSPEC.  If no arguments are
+     supplied, or only '-p' is given, 'trap' prints the list of commands
+     associated with each signal number in a form that may be reused as
+     shell input.  The '-l' option causes the shell to print a list of
+     signal names and their corresponding numbers.  Each SIGSPEC is
+     either a signal name or a signal number.  Signal names are case
+     insensitive and the 'SIG' prefix is optional.
+
+     If a SIGSPEC is '0' or 'EXIT', ARG is executed when the shell
+     exits.  If a SIGSPEC is 'DEBUG', the command ARG is executed before
+     every simple command, 'for' command, 'case' command, 'select'
+     command, every arithmetic 'for' command, and before the first
+     command executes in a shell function.  Refer to the description of
+     the 'extdebug' option to the 'shopt' builtin (*note The Shopt
+     Builtin::) for details of its effect on the 'DEBUG' trap.  If a
+     SIGSPEC is 'RETURN', the command ARG is executed each time a shell
+     function or a script executed with the '.' or 'source' builtins
+     finishes executing.
+
+     If a SIGSPEC is 'ERR', the command ARG is executed whenever a
+     pipeline (which may consist of a single simple command), a list, or
+     a compound command returns a non-zero exit status, subject to the
+     following conditions.  The 'ERR' trap is not executed if the failed
+     command is part of the command list immediately following an
+     'until' or 'while' keyword, part of the test following the 'if' or
+     'elif' reserved words, part of a command executed in a '&&' or '||'
+     list except the command following the final '&&' or '||', any
+     command in a pipeline but the last, or if the command's return
+     status is being inverted using '!'.  These are the same conditions
+     obeyed by the 'errexit' ('-e') option.
+
+     Signals ignored upon entry to the shell cannot be trapped or reset.
+     Trapped signals that are not being ignored are reset to their
+     original values in a subshell or subshell environment when one is
+     created.
+
+     The return status is zero unless a SIGSPEC does not specify a valid
+     signal.
+
+'umask'
+          umask [-p] [-S] [MODE]
+
+     Set the shell process's file creation mask to MODE.  If MODE begins
+     with a digit, it is interpreted as an octal number; if not, it is
+     interpreted as a symbolic mode mask similar to that accepted by the
+     'chmod' command.  If MODE is omitted, the current value of the mask
+     is printed.  If the '-S' option is supplied without a MODE
+     argument, the mask is printed in a symbolic format.  If the '-p'
+     option is supplied, and MODE is omitted, the output is in a form
+     that may be reused as input.  The return status is zero if the mode
+     is successfully changed or if no MODE argument is supplied, and
+     non-zero otherwise.
+
+     Note that when the mode is interpreted as an octal number, each
+     number of the umask is subtracted from '7'.  Thus, a umask of '022'
+     results in permissions of '755'.
+
+'unset'
+          unset [-fnv] [NAME]
+
+     Remove each variable or function NAME.  If the '-v' option is
+     given, each NAME refers to a shell variable and that variable is
+     removed.  If the '-f' option is given, the NAMEs refer to shell
+     functions, and the function definition is removed.  If the '-n'
+     option is supplied, and NAME is a variable with the 'nameref'
+     attribute, NAME will be unset rather than the variable it
+     references.  '-n' has no effect if the '-f' option is supplied.  If
+     no options are supplied, each NAME refers to a variable; if there
+     is no variable by that name, a function with that name, if any, is
+     unset.  Readonly variables and functions may not be unset.  Some
+     shell variables lose their special behavior if they are unset; such
+     behavior is noted in the description of the individual variables.
+     The return status is zero unless a NAME is readonly or may not be
+     unset.

+4.2 Bash Builtin Commands
+=========================
+
+This section describes builtin commands which are unique to or have been
+extended in Bash.  Some of these commands are specified in the POSIX
+standard.
+
+'alias'
+          alias [-p] [NAME[=VALUE] ...]
+
+     Without arguments or with the '-p' option, 'alias' prints the list
+     of aliases on the standard output in a form that allows them to be
+     reused as input.  If arguments are supplied, an alias is defined
+     for each NAME whose VALUE is given.  If no VALUE is given, the name
+     and value of the alias is printed.  Aliases are described in *note
+     Aliases::.
+
+'bind'
+          bind [-m KEYMAP] [-lpsvPSVX]
+          bind [-m KEYMAP] [-q FUNCTION] [-u FUNCTION] [-r KEYSEQ]
+          bind [-m KEYMAP] -f FILENAME
+          bind [-m KEYMAP] -x KEYSEQ:SHELL-COMMAND
+          bind [-m KEYMAP] KEYSEQ:FUNCTION-NAME
+          bind [-m KEYMAP] KEYSEQ:READLINE-COMMAND
+          bind READLINE-COMMAND-LINE
+
+     Display current Readline (*note Command Line Editing::) key and
+     function bindings, bind a key sequence to a Readline function or
+     macro, or set a Readline variable.  Each non-option argument is a
+     command as it would appear in a Readline initialization file (*note
+     Readline Init File::), but each binding or command must be passed
+     as a separate argument; e.g., '"\C-x\C-r":re-read-init-file'.
+
+     Options, if supplied, have the following meanings:
+
+     '-m KEYMAP'
+          Use KEYMAP as the keymap to be affected by the subsequent
+          bindings.  Acceptable KEYMAP names are 'emacs',
+          'emacs-standard', 'emacs-meta', 'emacs-ctlx', 'vi', 'vi-move',
+          'vi-command', and 'vi-insert'.  'vi' is equivalent to
+          'vi-command' ('vi-move' is also a synonym); 'emacs' is
+          equivalent to 'emacs-standard'.
+
+     '-l'
+          List the names of all Readline functions.
+
+     '-p'
+          Display Readline function names and bindings in such a way
+          that they can be used as input or in a Readline initialization
+          file.
+
+     '-P'
+          List current Readline function names and bindings.
+
+     '-v'
+          Display Readline variable names and values in such a way that
+          they can be used as input or in a Readline initialization
+          file.
+
+     '-V'
+          List current Readline variable names and values.
+
+     '-s'
+          Display Readline key sequences bound to macros and the strings
+          they output in such a way that they can be used as input or in
+          a Readline initialization file.
+
+     '-S'
+          Display Readline key sequences bound to macros and the strings
+          they output.
+
+     '-f FILENAME'
+          Read key bindings from FILENAME.
+
+     '-q FUNCTION'
+          Query about which keys invoke the named FUNCTION.
+
+     '-u FUNCTION'
+          Unbind all keys bound to the named FUNCTION.
+
+     '-r KEYSEQ'
+          Remove any current binding for KEYSEQ.
+
+     '-x KEYSEQ:SHELL-COMMAND'
+          Cause SHELL-COMMAND to be executed whenever KEYSEQ is entered.
+          When SHELL-COMMAND is executed, the shell sets the
+          'READLINE_LINE' variable to the contents of the Readline line
+          buffer and the 'READLINE_POINT' and 'READLINE_MARK' variables
+          to the current location of the insertion point and the saved
+          insertion point (the MARK), respectively.  The shell assigns
+          any numeric argument the user supplied to the
+          'READLINE_ARGUMENT' variable.  If there was no argument, that
+          variable is not set.  If the executed command changes the
+          value of any of 'READLINE_LINE', 'READLINE_POINT', or
+          'READLINE_MARK', those new values will be reflected in the
+          editing state.
+
+     '-X'
+          List all key sequences bound to shell commands and the
+          associated commands in a format that can be reused as input.
+
+     The return status is zero unless an invalid option is supplied or
+     an error occurs.
+
+'builtin'
+          builtin [SHELL-BUILTIN [ARGS]]
+
+     Run a shell builtin, passing it ARGS, and return its exit status.
+     This is useful when defining a shell function with the same name as
+     a shell builtin, retaining the functionality of the builtin within
+     the function.  The return status is non-zero if SHELL-BUILTIN is
+     not a shell builtin command.
+
+'caller'
+          caller [EXPR]
+
+     Returns the context of any active subroutine call (a shell function
+     or a script executed with the '.' or 'source' builtins).
+
+     Without EXPR, 'caller' displays the line number and source filename
+     of the current subroutine call.  If a non-negative integer is
+     supplied as EXPR, 'caller' displays the line number, subroutine
+     name, and source file corresponding to that position in the current
+     execution call stack.  This extra information may be used, for
+     example, to print a stack trace.  The current frame is frame 0.
+
+     The return value is 0 unless the shell is not executing a
+     subroutine call or EXPR does not correspond to a valid position in
+     the call stack.
+
+'command'
+          command [-pVv] COMMAND [ARGUMENTS ...]
+
+     Runs COMMAND with ARGUMENTS ignoring any shell function named
+     COMMAND.  Only shell builtin commands or commands found by
+     searching the 'PATH' are executed.  If there is a shell function
+     named 'ls', running 'command ls' within the function will execute
+     the external command 'ls' instead of calling the function
+     recursively.  The '-p' option means to use a default value for
+     'PATH' that is guaranteed to find all of the standard utilities.
+     The return status in this case is 127 if COMMAND cannot be found or
+     an error occurred, and the exit status of COMMAND otherwise.
+
+     If either the '-V' or '-v' option is supplied, a description of
+     COMMAND is printed.  The '-v' option causes a single word
+     indicating the command or file name used to invoke COMMAND to be
+     displayed; the '-V' option produces a more verbose description.  In
+     this case, the return status is zero if COMMAND is found, and
+     non-zero if not.
+
+'declare'
+          declare [-aAfFgiIlnrtux] [-p] [NAME[=VALUE] ...]
+
+     Declare variables and give them attributes.  If no NAMEs are given,
+     then display the values of variables instead.
+
+     The '-p' option will display the attributes and values of each
+     NAME.  When '-p' is used with NAME arguments, additional options,
+     other than '-f' and '-F', are ignored.
+
+     When '-p' is supplied without NAME arguments, 'declare' will
+     display the attributes and values of all variables having the
+     attributes specified by the additional options.  If no other
+     options are supplied with '-p', 'declare' will display the
+     attributes and values of all shell variables.  The '-f' option will
+     restrict the display to shell functions.
+
+     The '-F' option inhibits the display of function definitions; only
+     the function name and attributes are printed.  If the 'extdebug'
+     shell option is enabled using 'shopt' (*note The Shopt Builtin::),
+     the source file name and line number where each NAME is defined are
+     displayed as well.  '-F' implies '-f'.
+
+     The '-g' option forces variables to be created or modified at the
+     global scope, even when 'declare' is executed in a shell function.
+     It is ignored in all other cases.
+
+     The '-I' option causes local variables to inherit the attributes
+     (except the 'nameref' attribute) and value of any existing variable
+     with the same NAME at a surrounding scope.  If there is no existing
+     variable, the local variable is initially unset.
+
+     The following options can be used to restrict output to variables
+     with the specified attributes or to give variables attributes:
+
+     '-a'
+          Each NAME is an indexed array variable (*note Arrays::).
+
+     '-A'
+          Each NAME is an associative array variable (*note Arrays::).
+
+     '-f'
+          Use function names only.
+
+     '-i'
+          The variable is to be treated as an integer; arithmetic
+          evaluation (*note Shell Arithmetic::) is performed when the
+          variable is assigned a value.
+
+     '-l'
+          When the variable is assigned a value, all upper-case
+          characters are converted to lower-case.  The upper-case
+          attribute is disabled.
+
+     '-n'
+          Give each NAME the 'nameref' attribute, making it a name
+          reference to another variable.  That other variable is defined
+          by the value of NAME.  All references, assignments, and
+          attribute modifications to NAME, except for those using or
+          changing the '-n' attribute itself, are performed on the
+          variable referenced by NAME's value.  The nameref attribute
+          cannot be applied to array variables.
+
+     '-r'
+          Make NAMEs readonly.  These names cannot then be assigned
+          values by subsequent assignment statements or unset.
+
+     '-t'
+          Give each NAME the 'trace' attribute.  Traced functions
+          inherit the 'DEBUG' and 'RETURN' traps from the calling shell.
+          The trace attribute has no special meaning for variables.
+
+     '-u'
+          When the variable is assigned a value, all lower-case
+          characters are converted to upper-case.  The lower-case
+          attribute is disabled.
+
+     '-x'
+          Mark each NAME for export to subsequent commands via the
+          environment.
+
+     Using '+' instead of '-' turns off the attribute instead, with the
+     exceptions that '+a' and '+A' may not be used to destroy array
+     variables and '+r' will not remove the readonly attribute.  When
+     used in a function, 'declare' makes each NAME local, as with the
+     'local' command, unless the '-g' option is used.  If a variable
+     name is followed by =VALUE, the value of the variable is set to
+     VALUE.
+
+     When using '-a' or '-A' and the compound assignment syntax to
+     create array variables, additional attributes do not take effect
+     until subsequent assignments.
+
+     The return status is zero unless an invalid option is encountered,
+     an attempt is made to define a function using '-f foo=bar', an
+     attempt is made to assign a value to a readonly variable, an
+     attempt is made to assign a value to an array variable without
+     using the compound assignment syntax (*note Arrays::), one of the
+     NAMEs is not a valid shell variable name, an attempt is made to
+     turn off readonly status for a readonly variable, an attempt is
+     made to turn off array status for an array variable, or an attempt
+     is made to display a non-existent function with '-f'.
+
+'echo'
+          echo [-neE] [ARG ...]
+
+     Output the ARGs, separated by spaces, terminated with a newline.
+     The return status is 0 unless a write error occurs.  If '-n' is
+     specified, the trailing newline is suppressed.  If the '-e' option
+     is given, interpretation of the following backslash-escaped
+     characters is enabled.  The '-E' option disables the interpretation
+     of these escape characters, even on systems where they are
+     interpreted by default.  The 'xpg_echo' shell option may be used to
+     dynamically determine whether or not 'echo' expands these escape
+     characters by default.  'echo' does not interpret '--' to mean the
+     end of options.
+
+     'echo' interprets the following escape sequences:
+     '\a'
+          alert (bell)
+     '\b'
+          backspace
+     '\c'
+          suppress further output
+     '\e'
+     '\E'
+          escape
+     '\f'
+          form feed
+     '\n'
+          new line
+     '\r'
+          carriage return
+     '\t'
+          horizontal tab
+     '\v'
+          vertical tab
+     '\\'
+          backslash
+     '\0NNN'
+          the eight-bit character whose value is the octal value NNN
+          (zero to three octal digits)
+     '\xHH'
+          the eight-bit character whose value is the hexadecimal value
+          HH (one or two hex digits)
+     '\uHHHH'
+          the Unicode (ISO/IEC 10646) character whose value is the
+          hexadecimal value HHHH (one to four hex digits)
+     '\UHHHHHHHH'
+          the Unicode (ISO/IEC 10646) character whose value is the
+          hexadecimal value HHHHHHHH (one to eight hex digits)
+
+'enable'
+          enable [-a] [-dnps] [-f FILENAME] [NAME ...]
+
+     Enable and disable builtin shell commands.  Disabling a builtin
+     allows a disk command which has the same name as a shell builtin to
+     be executed without specifying a full pathname, even though the
+     shell normally searches for builtins before disk commands.  If '-n'
+     is used, the NAMEs become disabled.  Otherwise NAMEs are enabled.
+     For example, to use the 'test' binary found via '$PATH' instead of
+     the shell builtin version, type 'enable -n test'.
+
+     If the '-p' option is supplied, or no NAME arguments appear, a list
+     of shell builtins is printed.  With no other arguments, the list
+     consists of all enabled shell builtins.  The '-a' option means to
+     list each builtin with an indication of whether or not it is
+     enabled.
+
+     The '-f' option means to load the new builtin command NAME from
+     shared object FILENAME, on systems that support dynamic loading.
+     Bash will use the value of the 'BASH_LOADABLES_PATH' variable as a
+     colon-separated list of directories in which to search for
+     FILENAME.  The default is system-dependent.  The '-d' option will
+     delete a builtin loaded with '-f'.
+
+     If there are no options, a list of the shell builtins is displayed.
+     The '-s' option restricts 'enable' to the POSIX special builtins.
+     If '-s' is used with '-f', the new builtin becomes a special
+     builtin (*note Special Builtins::).
+
+     If no options are supplied and a NAME is not a shell builtin,
+     'enable' will attempt to load NAME from a shared object named NAME,
+     as if the command were 'enable -f NAME NAME'.
+
+     The return status is zero unless a NAME is not a shell builtin or
+     there is an error loading a new builtin from a shared object.
+
+'help'
+          help [-dms] [PATTERN]
+
+     Display helpful information about builtin commands.  If PATTERN is
+     specified, 'help' gives detailed help on all commands matching
+     PATTERN, otherwise a list of the builtins is printed.
+
+     Options, if supplied, have the following meanings:
+
+     '-d'
+          Display a short description of each PATTERN
+     '-m'
+          Display the description of each PATTERN in a manpage-like
+          format
+     '-s'
+          Display only a short usage synopsis for each PATTERN
+
+     The return status is zero unless no command matches PATTERN.
+
+'let'
+          let EXPRESSION [EXPRESSION ...]
+
+     The 'let' builtin allows arithmetic to be performed on shell
+     variables.  Each EXPRESSION is evaluated according to the rules
+     given below in *note Shell Arithmetic::.  If the last EXPRESSION
+     evaluates to 0, 'let' returns 1; otherwise 0 is returned.
+
+'local'
+          local [OPTION] NAME[=VALUE] ...
+
+     For each argument, a local variable named NAME is created, and
+     assigned VALUE.  The OPTION can be any of the options accepted by
+     'declare'.  'local' can only be used within a function; it makes
+     the variable NAME have a visible scope restricted to that function
+     and its children.  If NAME is '-', the set of shell options is made
+     local to the function in which 'local' is invoked: shell options
+     changed using the 'set' builtin inside the function are restored to
+     their original values when the function returns.  The restore is
+     effected as if a series of 'set' commands were executed to restore
+     the values that were in place before the function.  The return
+     status is zero unless 'local' is used outside a function, an
+     invalid NAME is supplied, or NAME is a readonly variable.
+
+'logout'
+          logout [N]
+
+     Exit a login shell, returning a status of N to the shell's parent.
+
+'mapfile'
+          mapfile [-d DELIM] [-n COUNT] [-O ORIGIN] [-s COUNT]
+              [-t] [-u FD] [-C CALLBACK] [-c QUANTUM] [ARRAY]
+
+     Read lines from the standard input into the indexed array variable
+     ARRAY, or from file descriptor FD if the '-u' option is supplied.
+     The variable 'MAPFILE' is the default ARRAY.  Options, if supplied,
+     have the following meanings:
+
+     '-d'
+          The first character of DELIM is used to terminate each input
+          line, rather than newline.  If DELIM is the empty string,
+          'mapfile' will terminate a line when it reads a NUL character.
+     '-n'
+          Copy at most COUNT lines.  If COUNT is 0, all lines are
+          copied.
+     '-O'
+          Begin assigning to ARRAY at index ORIGIN.  The default index
+          is 0.
+     '-s'
+          Discard the first COUNT lines read.
+     '-t'
+          Remove a trailing DELIM (default newline) from each line read.
+     '-u'
+          Read lines from file descriptor FD instead of the standard
+          input.
+     '-C'
+          Evaluate CALLBACK each time QUANTUM lines are read.  The '-c'
+          option specifies QUANTUM.
+     '-c'
+          Specify the number of lines read between each call to
+          CALLBACK.
+
+     If '-C' is specified without '-c', the default quantum is 5000.
+     When CALLBACK is evaluated, it is supplied the index of the next
+     array element to be assigned and the line to be assigned to that
+     element as additional arguments.  CALLBACK is evaluated after the
+     line is read but before the array element is assigned.
+
+     If not supplied with an explicit origin, 'mapfile' will clear ARRAY
+     before assigning to it.
+
+     'mapfile' returns successfully unless an invalid option or option
+     argument is supplied, ARRAY is invalid or unassignable, or ARRAY is
+     not an indexed array.
+
+'printf'
+          printf [-v VAR] FORMAT [ARGUMENTS]
+
+     Write the formatted ARGUMENTS to the standard output under the
+     control of the FORMAT.  The '-v' option causes the output to be
+     assigned to the variable VAR rather than being printed to the
+     standard output.
+
+     The FORMAT is a character string which contains three types of
+     objects: plain characters, which are simply copied to standard
+     output, character escape sequences, which are converted and copied
+     to the standard output, and format specifications, each of which
+     causes printing of the next successive ARGUMENT.  In addition to
+     the standard 'printf(1)' formats, 'printf' interprets the following
+     extensions:
+
+     '%b'
+          Causes 'printf' to expand backslash escape sequences in the
+          corresponding ARGUMENT in the same way as 'echo -e' (*note
+          Bash Builtins::).
+     '%q'
+          Causes 'printf' to output the corresponding ARGUMENT in a
+          format that can be reused as shell input.
+     '%Q'
+          like '%q', but applies any supplied precision to the ARGUMENT
+          before quoting it.
+     '%(DATEFMT)T'
+          Causes 'printf' to output the date-time string resulting from
+          using DATEFMT as a format string for 'strftime'(3).  The
+          corresponding ARGUMENT is an integer representing the number
+          of seconds since the epoch.  Two special argument values may
+          be used: -1 represents the current time, and -2 represents the
+          time the shell was invoked.  If no argument is specified,
+          conversion behaves as if -1 had been given.  This is an
+          exception to the usual 'printf' behavior.
+
+     The %b, %q, and %T directives all use the field width and precision
+     arguments from the format specification and write that many bytes
+     from (or use that wide a field for) the expanded argument, which
+     usually contains more characters than the original.
+
+     Arguments to non-string format specifiers are treated as C language
+     constants, except that a leading plus or minus sign is allowed, and
+     if the leading character is a single or double quote, the value is
+     the ASCII value of the following character.
+
+     The FORMAT is reused as necessary to consume all of the ARGUMENTS.
+     If the FORMAT requires more ARGUMENTS than are supplied, the extra
+     format specifications behave as if a zero value or null string, as
+     appropriate, had been supplied.  The return value is zero on
+     success, non-zero on failure.
+
+'read'
+          read [-ers] [-a ANAME] [-d DELIM] [-i TEXT] [-n NCHARS]
+              [-N NCHARS] [-p PROMPT] [-t TIMEOUT] [-u FD] [NAME ...]
+
+     One line is read from the standard input, or from the file
+     descriptor FD supplied as an argument to the '-u' option, split
+     into words as described above in *note Word Splitting::, and the
+     first word is assigned to the first NAME, the second word to the
+     second NAME, and so on.  If there are more words than names, the
+     remaining words and their intervening delimiters are assigned to
+     the last NAME.  If there are fewer words read from the input stream
+     than names, the remaining names are assigned empty values.  The
+     characters in the value of the 'IFS' variable are used to split the
+     line into words using the same rules the shell uses for expansion
+     (described above in *note Word Splitting::).  The backslash
+     character '\' may be used to remove any special meaning for the
+     next character read and for line continuation.
+
+     Options, if supplied, have the following meanings:
+
+     '-a ANAME'
+          The words are assigned to sequential indices of the array
+          variable ANAME, starting at 0.  All elements are removed from
+          ANAME before the assignment.  Other NAME arguments are
+          ignored.
+
+     '-d DELIM'
+          The first character of DELIM is used to terminate the input
+          line, rather than newline.  If DELIM is the empty string,
+          'read' will terminate a line when it reads a NUL character.
+
+     '-e'
+          Readline (*note Command Line Editing::) is used to obtain the
+          line.  Readline uses the current (or default, if line editing
+          was not previously active) editing settings, but uses
+          Readline's default filename completion.
+
+     '-i TEXT'
+          If Readline is being used to read the line, TEXT is placed
+          into the editing buffer before editing begins.
+
+     '-n NCHARS'
+          'read' returns after reading NCHARS characters rather than
+          waiting for a complete line of input, but honors a delimiter
+          if fewer than NCHARS characters are read before the delimiter.
+
+     '-N NCHARS'
+          'read' returns after reading exactly NCHARS characters rather
+          than waiting for a complete line of input, unless EOF is
+          encountered or 'read' times out.  Delimiter characters
+          encountered in the input are not treated specially and do not
+          cause 'read' to return until NCHARS characters are read.  The
+          result is not split on the characters in 'IFS'; the intent is
+          that the variable is assigned exactly the characters read
+          (with the exception of backslash; see the '-r' option below).
+
+     '-p PROMPT'
+          Display PROMPT, without a trailing newline, before attempting
+          to read any input.  The prompt is displayed only if input is
+          coming from a terminal.
+
+     '-r'
+          If this option is given, backslash does not act as an escape
+          character.  The backslash is considered to be part of the
+          line.  In particular, a backslash-newline pair may not then be
+          used as a line continuation.
+
+     '-s'
+          Silent mode.  If input is coming from a terminal, characters
+          are not echoed.
+
+     '-t TIMEOUT'
+          Cause 'read' to time out and return failure if a complete line
+          of input (or a specified number of characters) is not read
+          within TIMEOUT seconds.  TIMEOUT may be a decimal number with
+          a fractional portion following the decimal point.  This option
+          is only effective if 'read' is reading input from a terminal,
+          pipe, or other special file; it has no effect when reading
+          from regular files.  If 'read' times out, 'read' saves any
+          partial input read into the specified variable NAME.  If
+          TIMEOUT is 0, 'read' returns immediately, without trying to
+          read any data.  The exit status is 0 if input is available on
+          the specified file descriptor, or the read will return EOF,
+          non-zero otherwise.  The exit status is greater than 128 if
+          the timeout is exceeded.
+
+     '-u FD'
+          Read input from file descriptor FD.
+
+     If no NAMEs are supplied, the line read, without the ending
+     delimiter but otherwise unmodified, is assigned to the variable
+     'REPLY'.  The exit status is zero, unless end-of-file is
+     encountered, 'read' times out (in which case the status is greater
+     than 128), a variable assignment error (such as assigning to a
+     readonly variable) occurs, or an invalid file descriptor is
+     supplied as the argument to '-u'.
+
+'readarray'
+          readarray [-d DELIM] [-n COUNT] [-O ORIGIN] [-s COUNT]
+              [-t] [-u FD] [-C CALLBACK] [-c QUANTUM] [ARRAY]
+
+     Read lines from the standard input into the indexed array variable
+     ARRAY, or from file descriptor FD if the '-u' option is supplied.
+
+     A synonym for 'mapfile'.
+
+'source'
+          source FILENAME
+
+     A synonym for '.' (*note Bourne Shell Builtins::).
+
+'type'
+          type [-afptP] [NAME ...]
+
+     For each NAME, indicate how it would be interpreted if used as a
+     command name.
+
+     If the '-t' option is used, 'type' prints a single word which is
+     one of 'alias', 'function', 'builtin', 'file' or 'keyword', if NAME
+     is an alias, shell function, shell builtin, disk file, or shell
+     reserved word, respectively.  If the NAME is not found, then
+     nothing is printed, and 'type' returns a failure status.
+
+     If the '-p' option is used, 'type' either returns the name of the
+     disk file that would be executed, or nothing if '-t' would not
+     return 'file'.
+
+     The '-P' option forces a path search for each NAME, even if '-t'
+     would not return 'file'.
+
+     If a command is hashed, '-p' and '-P' print the hashed value, which
+     is not necessarily the file that appears first in '$PATH'.
+
+     If the '-a' option is used, 'type' returns all of the places that
+     contain an executable named FILE.  This includes aliases and
+     functions, if and only if the '-p' option is not also used.
+
+     If the '-f' option is used, 'type' does not attempt to find shell
+     functions, as with the 'command' builtin.
+
+     The return status is zero if all of the NAMEs are found, non-zero
+     if any are not found.
+
+'typeset'
+          typeset [-afFgrxilnrtux] [-p] [NAME[=VALUE] ...]
+
+     The 'typeset' command is supplied for compatibility with the Korn
+     shell.  It is a synonym for the 'declare' builtin command.
+
+'ulimit'
+          ulimit [-HS] -a
+          ulimit [-HS] [-bcdefiklmnpqrstuvxPRT] [LIMIT]
+
+     'ulimit' provides control over the resources available to processes
+     started by the shell, on systems that allow such control.  If an
+     option is given, it is interpreted as follows:
+
+     '-S'
+          Change and report the soft limit associated with a resource.
+
+     '-H'
+          Change and report the hard limit associated with a resource.
+
+     '-a'
+          All current limits are reported; no limits are set.
+
+     '-b'
+          The maximum socket buffer size.
+
+     '-c'
+          The maximum size of core files created.
+
+     '-d'
+          The maximum size of a process's data segment.
+
+     '-e'
+          The maximum scheduling priority ("nice").
+
+     '-f'
+          The maximum size of files written by the shell and its
+          children.
+
+     '-i'
+          The maximum number of pending signals.
+
+     '-k'
+          The maximum number of kqueues that may be allocated.
+
+     '-l'
+          The maximum size that may be locked into memory.
+
+     '-m'
+          The maximum resident set size (many systems do not honor this
+          limit).
+
+     '-n'
+          The maximum number of open file descriptors (most systems do
+          not allow this value to be set).
+
+     '-p'
+          The pipe buffer size.
+
+     '-q'
+          The maximum number of bytes in POSIX message queues.
+
+     '-r'
+          The maximum real-time scheduling priority.
+
+     '-s'
+          The maximum stack size.
+
+     '-t'
+          The maximum amount of cpu time in seconds.
+
+     '-u'
+          The maximum number of processes available to a single user.
+
+     '-v'
+          The maximum amount of virtual memory available to the shell,
+          and, on some systems, to its children.
+
+     '-x'
+          The maximum number of file locks.
+
+     '-P'
+          The maximum number of pseudoterminals.
+
+     '-R'
+          The maximum time a real-time process can run before blocking,
+          in microseconds.
+
+     '-T'
+          The maximum number of threads.
+
+     If LIMIT is given, and the '-a' option is not used, LIMIT is the
+     new value of the specified resource.  The special LIMIT values
+     'hard', 'soft', and 'unlimited' stand for the current hard limit,
+     the current soft limit, and no limit, respectively.  A hard limit
+     cannot be increased by a non-root user once it is set; a soft limit
+     may be increased up to the value of the hard limit.  Otherwise, the
+     current value of the soft limit for the specified resource is
+     printed, unless the '-H' option is supplied.  When more than one
+     resource is specified, the limit name and unit, if appropriate, are
+     printed before the value.  When setting new limits, if neither '-H'
+     nor '-S' is supplied, both the hard and soft limits are set.  If no
+     option is given, then '-f' is assumed.  Values are in 1024-byte
+     increments, except for '-t', which is in seconds; '-R', which is in
+     microseconds; '-p', which is in units of 512-byte blocks; '-P',
+     '-T', '-b', '-k', '-n' and '-u', which are unscaled values; and,
+     when in POSIX Mode (*note Bash POSIX Mode::), '-c' and '-f', which
+     are in 512-byte increments.
+
+     The return status is zero unless an invalid option or argument is
+     supplied, or an error occurs while setting a new limit.
+
+'unalias'
+          unalias [-a] [NAME ... ]
+
+     Remove each NAME from the list of aliases.  If '-a' is supplied,
+     all aliases are removed.  Aliases are described in *note Aliases::.

+
+4.3.1 The Set Builtin
+---------------------
+
+This builtin is so complicated that it deserves its own section.  'set'
+allows you to change the values of shell options and set the positional
+parameters, or to display the names and values of shell variables.
+
+'set'
+          set [-abefhkmnptuvxBCEHPT] [-o OPTION-NAME] [--] [-] [ARGUMENT ...]
+          set [+abefhkmnptuvxBCEHPT] [+o OPTION-NAME] [--] [-] [ARGUMENT ...]
+
+     If no options or arguments are supplied, 'set' displays the names
+     and values of all shell variables and functions, sorted according
+     to the current locale, in a format that may be reused as input for
+     setting or resetting the currently-set variables.  Read-only
+     variables cannot be reset.  In POSIX mode, only shell variables are
+     listed.
+
+     When options are supplied, they set or unset shell attributes.
+     Options, if specified, have the following meanings:
+
+     '-a'
+          Each variable or function that is created or modified is given
+          the export attribute and marked for export to the environment
+          of subsequent commands.
+
+     '-b'
+          Cause the status of terminated background jobs to be reported
+          immediately, rather than before printing the next primary
+          prompt.
+
+     '-e'
+          Exit immediately if a pipeline (*note Pipelines::), which may
+          consist of a single simple command (*note Simple Commands::),
+          a list (*note Lists::), or a compound command (*note Compound
+          Commands::) returns a non-zero status.  The shell does not
+          exit if the command that fails is part of the command list
+          immediately following a 'while' or 'until' keyword, part of
+          the test in an 'if' statement, part of any command executed in
+          a '&&' or '||' list except the command following the final
+          '&&' or '||', any command in a pipeline but the last, or if
+          the command's return status is being inverted with '!'.  If a
+          compound command other than a subshell returns a non-zero
+          status because a command failed while '-e' was being ignored,
+          the shell does not exit.  A trap on 'ERR', if set, is executed
+          before the shell exits.
+
+          This option applies to the shell environment and each subshell
+          environment separately (*note Command Execution
+          Environment::), and may cause subshells to exit before
+          executing all the commands in the subshell.
+
+          If a compound command or shell function executes in a context
+          where '-e' is being ignored, none of the commands executed
+          within the compound command or function body will be affected
+          by the '-e' setting, even if '-e' is set and a command returns
+          a failure status.  If a compound command or shell function
+          sets '-e' while executing in a context where '-e' is ignored,
+          that setting will not have any effect until the compound
+          command or the command containing the function call completes.
+
+     '-f'
+          Disable filename expansion (globbing).
+
+     '-h'
+          Locate and remember (hash) commands as they are looked up for
+          execution.  This option is enabled by default.
+
+     '-k'
+          All arguments in the form of assignment statements are placed
+          in the environment for a command, not just those that precede
+          the command name.
+
+     '-m'
+          Job control is enabled (*note Job Control::).  All processes
+          run in a separate process group.  When a background job
+          completes, the shell prints a line containing its exit status.
+
+     '-n'
+          Read commands but do not execute them.  This may be used to
+          check a script for syntax errors.  This option is ignored by
+          interactive shells.
+
+     '-o OPTION-NAME'
+
+          Set the option corresponding to OPTION-NAME:
+
+          'allexport'
+               Same as '-a'.
+
+          'braceexpand'
+               Same as '-B'.
+
+          'emacs'
+               Use an 'emacs'-style line editing interface (*note
+               Command Line Editing::).  This also affects the editing
+               interface used for 'read -e'.
+
+          'errexit'
+               Same as '-e'.
+
+          'errtrace'
+               Same as '-E'.
+
+          'functrace'
+               Same as '-T'.
+
+          'hashall'
+               Same as '-h'.
+
+          'histexpand'
+               Same as '-H'.
+
+          'history'
+               Enable command history, as described in *note Bash
+               History Facilities::.  This option is on by default in
+               interactive shells.
+
+          'ignoreeof'
+               An interactive shell will not exit upon reading EOF.
+
+          'keyword'
+               Same as '-k'.
+
+          'monitor'
+               Same as '-m'.
+
+          'noclobber'
+               Same as '-C'.
+
+          'noexec'
+               Same as '-n'.
+
+          'noglob'
+               Same as '-f'.
+
+          'nolog'
+               Currently ignored.
+
+          'notify'
+               Same as '-b'.
+
+          'nounset'
+               Same as '-u'.
+
+          'onecmd'
+               Same as '-t'.
+
+          'physical'
+               Same as '-P'.
+
+          'pipefail'
+               If set, the return value of a pipeline is the value of
+               the last (rightmost) command to exit with a non-zero
+               status, or zero if all commands in the pipeline exit
+               successfully.  This option is disabled by default.
+
+          'posix'
+               Change the behavior of Bash where the default operation
+               differs from the POSIX standard to match the standard
+               (*note Bash POSIX Mode::).  This is intended to make Bash
+               behave as a strict superset of that standard.
+
+          'privileged'
+               Same as '-p'.
+
+          'verbose'
+               Same as '-v'.
+
+          'vi'
+               Use a 'vi'-style line editing interface.  This also
+               affects the editing interface used for 'read -e'.
+
+          'xtrace'
+               Same as '-x'.
+
+     '-p'
+          Turn on privileged mode.  In this mode, the '$BASH_ENV' and
+          '$ENV' files are not processed, shell functions are not
+          inherited from the environment, and the 'SHELLOPTS',
+          'BASHOPTS', 'CDPATH' and 'GLOBIGNORE' variables, if they
+          appear in the environment, are ignored.  If the shell is
+          started with the effective user (group) id not equal to the
+          real user (group) id, and the '-p' option is not supplied,
+          these actions are taken and the effective user id is set to
+          the real user id.  If the '-p' option is supplied at startup,
+          the effective user id is not reset.  Turning this option off
+          causes the effective user and group ids to be set to the real
+          user and group ids.
+
+     '-r'
+          Enable restricted shell mode.  This option cannot be unset
+          once it has been set.
+
+     '-t'
+          Exit after reading and executing one command.
+
+     '-u'
+          Treat unset variables and parameters other than the special
+          parameters '@' or '*', or array variables subscripted with '@'
+          or '*', as an error when performing parameter expansion.  An
+          error message will be written to the standard error, and a
+          non-interactive shell will exit.
+
+     '-v'
+          Print shell input lines as they are read.
+
+     '-x'
+          Print a trace of simple commands, 'for' commands, 'case'
+          commands, 'select' commands, and arithmetic 'for' commands and
+          their arguments or associated word lists after they are
+          expanded and before they are executed.  The value of the 'PS4'
+          variable is expanded and the resultant value is printed before
+          the command and its expanded arguments.
+
+     '-B'
+          The shell will perform brace expansion (*note Brace
+          Expansion::).  This option is on by default.
+
+     '-C'
+          Prevent output redirection using '>', '>&', and '<>' from
+          overwriting existing files.
+
+     '-E'
+          If set, any trap on 'ERR' is inherited by shell functions,
+          command substitutions, and commands executed in a subshell
+          environment.  The 'ERR' trap is normally not inherited in such
+          cases.
+
+     '-H'
+          Enable '!' style history substitution (*note History
+          Interaction::).  This option is on by default for interactive
+          shells.
+
+     '-P'
+          If set, do not resolve symbolic links when performing commands
+          such as 'cd' which change the current directory.  The physical
+          directory is used instead.  By default, Bash follows the
+          logical chain of directories when performing commands which
+          change the current directory.
+
+          For example, if '/usr/sys' is a symbolic link to
+          '/usr/local/sys' then:
+               $ cd /usr/sys; echo $PWD
+               /usr/sys
+               $ cd ..; pwd
+               /usr
+
+          If 'set -P' is on, then:
+               $ cd /usr/sys; echo $PWD
+               /usr/local/sys
+               $ cd ..; pwd
+               /usr/local
+
+     '-T'
+          If set, any trap on 'DEBUG' and 'RETURN' are inherited by
+          shell functions, command substitutions, and commands executed
+          in a subshell environment.  The 'DEBUG' and 'RETURN' traps are
+          normally not inherited in such cases.
+
+     '--'
+          If no arguments follow this option, then the positional
+          parameters are unset.  Otherwise, the positional parameters
+          are set to the ARGUMENTS, even if some of them begin with a
+          '-'.
+
+     '-'
+          Signal the end of options, cause all remaining ARGUMENTS to be
+          assigned to the positional parameters.  The '-x' and '-v'
+          options are turned off.  If there are no arguments, the
+          positional parameters remain unchanged.
+
+     Using '+' rather than '-' causes these options to be turned off.
+     The options can also be used upon invocation of the shell.  The
+     current set of options may be found in '$-'.
+
+     The remaining N ARGUMENTS are positional parameters and are
+     assigned, in order, to '$1', '$2', ... '$N'.  The special parameter
+     '#' is set to N.
+
+     The return status is always zero unless an invalid option is
+     supplied.

+File: bash.info,  Node: The Shopt Builtin,  Prev: The Set Builtin,  Up: Modifying Shell Behavior
+
+4.3.2 The Shopt Builtin
+-----------------------
+
+This builtin allows you to change additional shell optional behavior.
+
+'shopt'
+          shopt [-pqsu] [-o] [OPTNAME ...]
+
+     Toggle the values of settings controlling optional shell behavior.
+     The settings can be either those listed below, or, if the '-o'
+     option is used, those available with the '-o' option to the 'set'
+     builtin command (*note The Set Builtin::).  With no options, or
+     with the '-p' option, a list of all settable options is displayed,
+     with an indication of whether or not each is set; if OPTNAMEs are
+     supplied, the output is restricted to those options.  The '-p'
+     option causes output to be displayed in a form that may be reused
+     as input.  Other options have the following meanings:
+
+     '-s'
+          Enable (set) each OPTNAME.
+
+     '-u'
+          Disable (unset) each OPTNAME.
+
+     '-q'
+          Suppresses normal output; the return status indicates whether
+          the OPTNAME is set or unset.  If multiple OPTNAME arguments
+          are given with '-q', the return status is zero if all OPTNAMEs
+          are enabled; non-zero otherwise.
+
+     '-o'
+          Restricts the values of OPTNAME to be those defined for the
+          '-o' option to the 'set' builtin (*note The Set Builtin::).
+
+     If either '-s' or '-u' is used with no OPTNAME arguments, 'shopt'
+     shows only those options which are set or unset, respectively.
+
+     Unless otherwise noted, the 'shopt' options are disabled (off) by
+     default.
+
+     The return status when listing options is zero if all OPTNAMEs are
+     enabled, non-zero otherwise.  When setting or unsetting options,
+     the return status is zero unless an OPTNAME is not a valid shell
+     option.
+
+     The list of 'shopt' options is:
+
+     'assoc_expand_once'
+          If set, the shell suppresses multiple evaluation of
+          associative array subscripts during arithmetic expression
+          evaluation, while executing builtins that can perform variable
+          assignments, and while executing builtins that perform array
+          dereferencing.
+
+     'autocd'
+          If set, a command name that is the name of a directory is
+          executed as if it were the argument to the 'cd' command.  This
+          option is only used by interactive shells.
+
+     'cdable_vars'
+          If this is set, an argument to the 'cd' builtin command that
+          is not a directory is assumed to be the name of a variable
+          whose value is the directory to change to.
+
+     'cdspell'
+          If set, minor errors in the spelling of a directory component
+          in a 'cd' command will be corrected.  The errors checked for
+          are transposed characters, a missing character, and a
+          character too many.  If a correction is found, the corrected
+          path is printed, and the command proceeds.  This option is
+          only used by interactive shells.
+
+     'checkhash'
+          If this is set, Bash checks that a command found in the hash
+          table exists before trying to execute it.  If a hashed command
+          no longer exists, a normal path search is performed.
+
+     'checkjobs'
+          If set, Bash lists the status of any stopped and running jobs
+          before exiting an interactive shell.  If any jobs are running,
+          this causes the exit to be deferred until a second exit is
+          attempted without an intervening command (*note Job
+          Control::).  The shell always postpones exiting if any jobs
+          are stopped.
+
+     'checkwinsize'
+          If set, Bash checks the window size after each external
+          (non-builtin) command and, if necessary, updates the values of
+          'LINES' and 'COLUMNS'.  This option is enabled by default.
+
+     'cmdhist'
+          If set, Bash attempts to save all lines of a multiple-line
+          command in the same history entry.  This allows easy
+          re-editing of multi-line commands.  This option is enabled by
+          default, but only has an effect if command history is enabled
+          (*note Bash History Facilities::).
+
+     'compat31'
+     'compat32'
+     'compat40'
+     'compat41'
+     'compat42'
+     'compat43'
+     'compat44'
+          These control aspects of the shell's compatibility mode (*note
+          Shell Compatibility Mode::).
+
+     'complete_fullquote'
+          If set, Bash quotes all shell metacharacters in filenames and
+          directory names when performing completion.  If not set, Bash
+          removes metacharacters such as the dollar sign from the set of
+          characters that will be quoted in completed filenames when
+          these metacharacters appear in shell variable references in
+          words to be completed.  This means that dollar signs in
+          variable names that expand to directories will not be quoted;
+          however, any dollar signs appearing in filenames will not be
+          quoted, either.  This is active only when bash is using
+          backslashes to quote completed filenames.  This variable is
+          set by default, which is the default Bash behavior in versions
+          through 4.2.
+
+     'direxpand'
+          If set, Bash replaces directory names with the results of word
+          expansion when performing filename completion.  This changes
+          the contents of the Readline editing buffer.  If not set, Bash
+          attempts to preserve what the user typed.
+
+     'dirspell'
+          If set, Bash attempts spelling correction on directory names
+          during word completion if the directory name initially
+          supplied does not exist.
+
+     'dotglob'
+          If set, Bash includes filenames beginning with a '.'  in the
+          results of filename expansion.  The filenames '.' and '..'
+          must always be matched explicitly, even if 'dotglob' is set.
+
+     'execfail'
+          If this is set, a non-interactive shell will not exit if it
+          cannot execute the file specified as an argument to the 'exec'
+          builtin command.  An interactive shell does not exit if 'exec'
+          fails.
+
+     'expand_aliases'
+          If set, aliases are expanded as described below under Aliases,
+          *note Aliases::.  This option is enabled by default for
+          interactive shells.
+
+     'extdebug'
+          If set at shell invocation, or in a shell startup file,
+          arrange to execute the debugger profile before the shell
+          starts, identical to the '--debugger' option.  If set after
+          invocation, behavior intended for use by debuggers is enabled:
+
+            1. The '-F' option to the 'declare' builtin (*note Bash
+               Builtins::) displays the source file name and line number
+               corresponding to each function name supplied as an
+               argument.
+
+            2. If the command run by the 'DEBUG' trap returns a non-zero
+               value, the next command is skipped and not executed.
+
+            3. If the command run by the 'DEBUG' trap returns a value of
+               2, and the shell is executing in a subroutine (a shell
+               function or a shell script executed by the '.' or
+               'source' builtins), the shell simulates a call to
+               'return'.
+
+            4. 'BASH_ARGC' and 'BASH_ARGV' are updated as described in
+               their descriptions (*note Bash Variables::).
+
+            5. Function tracing is enabled: command substitution, shell
+               functions, and subshells invoked with '( COMMAND )'
+               inherit the 'DEBUG' and 'RETURN' traps.
+
+            6. Error tracing is enabled: command substitution, shell
+               functions, and subshells invoked with '( COMMAND )'
+               inherit the 'ERR' trap.
+
+     'extglob'
+          If set, the extended pattern matching features described above
+          (*note Pattern Matching::) are enabled.
+
+     'extquote'
+          If set, '$'STRING'' and '$"STRING"' quoting is performed
+          within '${PARAMETER}' expansions enclosed in double quotes.
+          This option is enabled by default.
+
+     'failglob'
+          If set, patterns which fail to match filenames during filename
+          expansion result in an expansion error.
+
+     'force_fignore'
+          If set, the suffixes specified by the 'FIGNORE' shell variable
+          cause words to be ignored when performing word completion even
+          if the ignored words are the only possible completions.  *Note
+          Bash Variables::, for a description of 'FIGNORE'.  This option
+          is enabled by default.
+
+     'globasciiranges'
+          If set, range expressions used in pattern matching bracket
+          expressions (*note Pattern Matching::) behave as if in the
+          traditional C locale when performing comparisons.  That is,
+          the current locale's collating sequence is not taken into
+          account, so 'b' will not collate between 'A' and 'B', and
+          upper-case and lower-case ASCII characters will collate
+          together.
+
+     'globskipdots'
+          If set, filename expansion will never match the filenames '.'
+          and '..', even if the pattern begins with a '.'.  This option
+          is enabled by default.
+
+     'globstar'
+          If set, the pattern '**' used in a filename expansion context
+          will match all files and zero or more directories and
+          subdirectories.  If the pattern is followed by a '/', only
+          directories and subdirectories match.
+
+     'gnu_errfmt'
+          If set, shell error messages are written in the standard GNU
+          error message format.
+
+     'histappend'
+          If set, the history list is appended to the file named by the
+          value of the 'HISTFILE' variable when the shell exits, rather
+          than overwriting the file.
+
+     'histreedit'
+          If set, and Readline is being used, a user is given the
+          opportunity to re-edit a failed history substitution.
+
+     'histverify'
+          If set, and Readline is being used, the results of history
+          substitution are not immediately passed to the shell parser.
+          Instead, the resulting line is loaded into the Readline
+          editing buffer, allowing further modification.
+
+     'hostcomplete'
+          If set, and Readline is being used, Bash will attempt to
+          perform hostname completion when a word containing a '@' is
+          being completed (*note Commands For Completion::).  This
+          option is enabled by default.
+
+     'huponexit'
+          If set, Bash will send 'SIGHUP' to all jobs when an
+          interactive login shell exits (*note Signals::).
+
+     'inherit_errexit'
+          If set, command substitution inherits the value of the
+          'errexit' option, instead of unsetting it in the subshell
+          environment.  This option is enabled when POSIX mode is
+          enabled.
+
+     'interactive_comments'
+          Allow a word beginning with '#' to cause that word and all
+          remaining characters on that line to be ignored in an
+          interactive shell.  This option is enabled by default.
+
+     'lastpipe'
+          If set, and job control is not active, the shell runs the last
+          command of a pipeline not executed in the background in the
+          current shell environment.
+
+     'lithist'
+          If enabled, and the 'cmdhist' option is enabled, multi-line
+          commands are saved to the history with embedded newlines
+          rather than using semicolon separators where possible.
+
+     'localvar_inherit'
+          If set, local variables inherit the value and attributes of a
+          variable of the same name that exists at a previous scope
+          before any new value is assigned.  The 'nameref' attribute is
+          not inherited.
+
+     'localvar_unset'
+          If set, calling 'unset' on local variables in previous
+          function scopes marks them so subsequent lookups find them
+          unset until that function returns.  This is identical to the
+          behavior of unsetting local variables at the current function
+          scope.
+
+     'login_shell'
+          The shell sets this option if it is started as a login shell
+          (*note Invoking Bash::).  The value may not be changed.
+
+     'mailwarn'
+          If set, and a file that Bash is checking for mail has been
+          accessed since the last time it was checked, the message '"The
+          mail in MAILFILE has been read"' is displayed.
+
+     'no_empty_cmd_completion'
+          If set, and Readline is being used, Bash will not attempt to
+          search the 'PATH' for possible completions when completion is
+          attempted on an empty line.
+
+     'nocaseglob'
+          If set, Bash matches filenames in a case-insensitive fashion
+          when performing filename expansion.
+
+     'nocasematch'
+          If set, Bash matches patterns in a case-insensitive fashion
+          when performing matching while executing 'case' or '[['
+          conditional commands (*note Conditional Constructs::, when
+          performing pattern substitution word expansions, or when
+          filtering possible completions as part of programmable
+          completion.
+
+     'noexpand_translation'
+          If set, Bash encloses the translated results of $"..."
+          quoting in single quotes instead of double quotes.  If the
+          string is not translated, this has no effect.
+
+     'nullglob'
+          If set, Bash allows filename patterns which match no files to
+          expand to a null string, rather than themselves.
+
+     'patsub_replacement'
+          If set, Bash expands occurrences of '&' in the replacement
+          string of pattern substitution to the text matched by the
+          pattern, as described above (*note Shell Parameter
+          Expansion::).  This option is enabled by default.
+
+     'progcomp'
+          If set, the programmable completion facilities (*note
+          Programmable Completion::) are enabled.  This option is
+          enabled by default.
+
+     'progcomp_alias'
+          If set, and programmable completion is enabled, Bash treats a
+          command name that doesn't have any completions as a possible
+          alias and attempts alias expansion.  If it has an alias, Bash
+          attempts programmable completion using the command word
+          resulting from the expanded alias.
+
+     'promptvars'
+          If set, prompt strings undergo parameter expansion, command
+          substitution, arithmetic expansion, and quote removal after
+          being expanded as described below (*note Controlling the
+          Prompt::).  This option is enabled by default.
+
+     'restricted_shell'
+          The shell sets this option if it is started in restricted mode
+          (*note The Restricted Shell::).  The value may not be changed.
+          This is not reset when the startup files are executed,
+          allowing the startup files to discover whether or not a shell
+          is restricted.
+
+     'shift_verbose'
+          If this is set, the 'shift' builtin prints an error message
+          when the shift count exceeds the number of positional
+          parameters.
+
+     'sourcepath'
+          If set, the '.' ('source') builtin uses the value of 'PATH' to
+          find the directory containing the file supplied as an
+          argument.  This option is enabled by default.
+
+     'varredir_close'
+          If set, the shell automatically closes file descriptors
+          assigned using the '{varname}' redirection syntax (*note
+          Redirections::) instead of leaving them open when the command
+          completes.
+
+     'xpg_echo'
+          If set, the 'echo' builtin expands backslash-escape sequences
+          by default.

+
+4.4 Special Builtins
+====================
+
+For historical reasons, the POSIX standard has classified several
+builtin commands as _special_.  When Bash is executing in POSIX mode,
+the special builtins differ from other builtin commands in three
+respects:
+
+  1. Special builtins are found before shell functions during command
+     lookup.
+
+  2. If a special builtin returns an error status, a non-interactive
+     shell exits.
+
+  3. Assignment statements preceding the command stay in effect in the
+     shell environment after the command completes.
+
+   When Bash is not executing in POSIX mode, these builtins behave no
+differently than the rest of the Bash builtin commands.  The Bash POSIX
+mode is described in *note Bash POSIX Mode::.
+
+   These are the POSIX special builtins:
+     break : . continue eval exec exit export readonly return set
+     shift trap unset

+* Bash Variables::		List of variables that exist in Bash.
+
+This chapter describes the shell variables that Bash uses.  Bash
+automatically assigns default values to a number of variables.
+
+
+File: bash.info,  Node: Bourne Shell Variables,  Next: Bash Variables,  Up: Shell Variables
+
+5.1 Bourne Shell Variables
+==========================
+
+Bash uses certain shell variables in the same way as the Bourne shell.
+In some cases, Bash assigns a default value to the variable.
+
+'CDPATH'
+     A colon-separated list of directories used as a search path for the
+     'cd' builtin command.
+
+'HOME'
+     The current user's home directory; the default for the 'cd' builtin
+     command.  The value of this variable is also used by tilde
+     expansion (*note Tilde Expansion::).
+
+'IFS'
+     A list of characters that separate fields; used when the shell
+     splits words as part of expansion.
+
+'MAIL'
+     If this parameter is set to a filename or directory name and the
+     'MAILPATH' variable is not set, Bash informs the user of the
+     arrival of mail in the specified file or Maildir-format directory.
+
+'MAILPATH'
+     A colon-separated list of filenames which the shell periodically
+     checks for new mail.  Each list entry can specify the message that
+     is printed when new mail arrives in the mail file by separating the
+     filename from the message with a '?'.  When used in the text of the
+     message, '$_' expands to the name of the current mail file.
+
+'OPTARG'
+     The value of the last option argument processed by the 'getopts'
+     builtin.
+
+'OPTIND'
+     The index of the last option argument processed by the 'getopts'
+     builtin.
+
+'PATH'
+     A colon-separated list of directories in which the shell looks for
+     commands.  A zero-length (null) directory name in the value of
+     'PATH' indicates the current directory.  A null directory name may
+     appear as two adjacent colons, or as an initial or trailing colon.
+
+'PS1'
+     The primary prompt string.  The default value is '\s-\v\$ '.  *Note
+     Controlling the Prompt::, for the complete list of escape sequences
+     that are expanded before 'PS1' is displayed.
+
+'PS2'
+     The secondary prompt string.  The default value is '> '.  'PS2' is
+     expanded in the same way as 'PS1' before being displayed.
+
+
+File: bash.info,  Node: Bash Variables,  Prev: Bourne Shell Variables,  Up: Shell Variables
+
+5.2 Bash Variables
+==================
+
+These variables are set or used by Bash, but other shells do not
+normally treat them specially.
+
+   A few variables used by Bash are described in different chapters:
+variables for controlling the job control facilities (*note Job Control
+Variables::).
+
+'_'
+     ($_, an underscore.)  At shell startup, set to the pathname used to
+     invoke the shell or shell script being executed as passed in the
+     environment or argument list.  Subsequently, expands to the last
+     argument to the previous simple command executed in the foreground,
+     after expansion.  Also set to the full pathname used to invoke each
+     command executed and placed in the environment exported to that
+     command.  When checking mail, this parameter holds the name of the
+     mail file.
+
+'BASH'
+     The full pathname used to execute the current instance of Bash.
+
+'BASHOPTS'
+     A colon-separated list of enabled shell options.  Each word in the
+     list is a valid argument for the '-s' option to the 'shopt' builtin
+     command (*note The Shopt Builtin::).  The options appearing in
+     'BASHOPTS' are those reported as 'on' by 'shopt'.  If this variable
+     is in the environment when Bash starts up, each shell option in the
+     list will be enabled before reading any startup files.  This
+     variable is readonly.
+
+'BASHPID'
+     Expands to the process ID of the current Bash process.  This
+     differs from '$$' under certain circumstances, such as subshells
+     that do not require Bash to be re-initialized.  Assignments to
+     'BASHPID' have no effect.  If 'BASHPID' is unset, it loses its
+     special properties, even if it is subsequently reset.
+
+'BASH_ALIASES'
+     An associative array variable whose members correspond to the
+     internal list of aliases as maintained by the 'alias' builtin.
+     (*note Bourne Shell Builtins::).  Elements added to this array
+     appear in the alias list; however, unsetting array elements
+     currently does not cause aliases to be removed from the alias list.
+     If 'BASH_ALIASES' is unset, it loses its special properties, even
+     if it is subsequently reset.
+
+'BASH_ARGC'
+     An array variable whose values are the number of parameters in each
+     frame of the current bash execution call stack.  The number of
+     parameters to the current subroutine (shell function or script
+     executed with '.' or 'source') is at the top of the stack.  When a
+     subroutine is executed, the number of parameters passed is pushed
+     onto 'BASH_ARGC'.  The shell sets 'BASH_ARGC' only when in extended
+     debugging mode (see *note The Shopt Builtin:: for a description of
+     the 'extdebug' option to the 'shopt' builtin).  Setting 'extdebug'
+     after the shell has started to execute a script, or referencing
+     this variable when 'extdebug' is not set, may result in
+     inconsistent values.
+
+'BASH_ARGV'
+     An array variable containing all of the parameters in the current
+     bash execution call stack.  The final parameter of the last
+     subroutine call is at the top of the stack; the first parameter of
+     the initial call is at the bottom.  When a subroutine is executed,
+     the parameters supplied are pushed onto 'BASH_ARGV'.  The shell
+     sets 'BASH_ARGV' only when in extended debugging mode (see *note
+     The Shopt Builtin:: for a description of the 'extdebug' option to
+     the 'shopt' builtin).  Setting 'extdebug' after the shell has
+     started to execute a script, or referencing this variable when
+     'extdebug' is not set, may result in inconsistent values.
+
+'BASH_ARGV0'
+     When referenced, this variable expands to the name of the shell or
+     shell script (identical to '$0'; *Note Special Parameters::, for
+     the description of special parameter 0).  Assignment to
+     'BASH_ARGV0' causes the value assigned to also be assigned to '$0'.
+     If 'BASH_ARGV0' is unset, it loses its special properties, even if
+     it is subsequently reset.
+
+'BASH_CMDS'
+     An associative array variable whose members correspond to the
+     internal hash table of commands as maintained by the 'hash' builtin
+     (*note Bourne Shell Builtins::).  Elements added to this array
+     appear in the hash table; however, unsetting array elements
+     currently does not cause command names to be removed from the hash
+     table.  If 'BASH_CMDS' is unset, it loses its special properties,
+     even if it is subsequently reset.
+
+'BASH_COMMAND'
+     The command currently being executed or about to be executed,
+     unless the shell is executing a command as the result of a trap, in
+     which case it is the command executing at the time of the trap.  If
+     'BASH_COMMAND' is unset, it loses its special properties, even if
+     it is subsequently reset.
+
+'BASH_COMPAT'
+     The value is used to set the shell's compatibility level.  *Note
+     Shell Compatibility Mode::, for a description of the various
+     compatibility levels and their effects.  The value may be a decimal
+     number (e.g., 4.2) or an integer (e.g., 42) corresponding to the
+     desired compatibility level.  If 'BASH_COMPAT' is unset or set to
+     the empty string, the compatibility level is set to the default for
+     the current version.  If 'BASH_COMPAT' is set to a value that is
+     not one of the valid compatibility levels, the shell prints an
+     error message and sets the compatibility level to the default for
+     the current version.  The valid values correspond to the
+     compatibility levels described below (*note Shell Compatibility
+     Mode::).  For example, 4.2 and 42 are valid values that correspond
+     to the 'compat42' 'shopt' option and set the compatibility level to
+     42.  The current version is also a valid value.
+
+'BASH_ENV'
+     If this variable is set when Bash is invoked to execute a shell
+     script, its value is expanded and used as the name of a startup
+     file to read before executing the script.  *Note Bash Startup
+     Files::.
+
+'BASH_EXECUTION_STRING'
+     The command argument to the '-c' invocation option.
+
+'BASH_LINENO'
+     An array variable whose members are the line numbers in source
+     files where each corresponding member of 'FUNCNAME' was invoked.
+     '${BASH_LINENO[$i]}' is the line number in the source file
+     ('${BASH_SOURCE[$i+1]}') where '${FUNCNAME[$i]}' was called (or
+     '${BASH_LINENO[$i-1]}' if referenced within another shell
+     function).  Use 'LINENO' to obtain the current line number.
+
+'BASH_LOADABLES_PATH'
+     A colon-separated list of directories in which the shell looks for
+     dynamically loadable builtins specified by the 'enable' command.
+
+'BASH_REMATCH'
+     An array variable whose members are assigned by the '=~' binary
+     operator to the '[[' conditional command (*note Conditional
+     Constructs::).  The element with index 0 is the portion of the
+     string matching the entire regular expression.  The element with
+     index N is the portion of the string matching the Nth parenthesized
+     subexpression.
+
+'BASH_SOURCE'
+     An array variable whose members are the source filenames where the
+     corresponding shell function names in the 'FUNCNAME' array variable
+     are defined.  The shell function '${FUNCNAME[$i]}' is defined in
+     the file '${BASH_SOURCE[$i]}' and called from
+     '${BASH_SOURCE[$i+1]}'
+
+'BASH_SUBSHELL'
+     Incremented by one within each subshell or subshell environment
+     when the shell begins executing in that environment.  The initial
+     value is 0.  If 'BASH_SUBSHELL' is unset, it loses its special
+     properties, even if it is subsequently reset.
+
+'BASH_VERSINFO'
+     A readonly array variable (*note Arrays::) whose members hold
+     version information for this instance of Bash.  The values assigned
+     to the array members are as follows:
+
+     'BASH_VERSINFO[0]'
+          The major version number (the "release").
+
+     'BASH_VERSINFO[1]'
+          The minor version number (the "version").
+
+     'BASH_VERSINFO[2]'
+          The patch level.
+
+     'BASH_VERSINFO[3]'
+          The build version.
+
+     'BASH_VERSINFO[4]'
+          The release status (e.g., 'beta1').
+
+     'BASH_VERSINFO[5]'
+          The value of 'MACHTYPE'.
+
+'BASH_VERSION'
+     The version number of the current instance of Bash.
+
+'BASH_XTRACEFD'
+     If set to an integer corresponding to a valid file descriptor, Bash
+     will write the trace output generated when 'set -x' is enabled to
+     that file descriptor.  This allows tracing output to be separated
+     from diagnostic and error messages.  The file descriptor is closed
+     when 'BASH_XTRACEFD' is unset or assigned a new value.  Unsetting
+     'BASH_XTRACEFD' or assigning it the empty string causes the trace
+     output to be sent to the standard error.  Note that setting
+     'BASH_XTRACEFD' to 2 (the standard error file descriptor) and then
+     unsetting it will result in the standard error being closed.
+
+'CHILD_MAX'
+     Set the number of exited child status values for the shell to
+     remember.  Bash will not allow this value to be decreased below a
+     POSIX-mandated minimum, and there is a maximum value (currently
+     8192) that this may not exceed.  The minimum value is
+     system-dependent.
+
+'COLUMNS'
+     Used by the 'select' command to determine the terminal width when
+     printing selection lists.  Automatically set if the 'checkwinsize'
+     option is enabled (*note The Shopt Builtin::), or in an interactive
+     shell upon receipt of a 'SIGWINCH'.
+
+'COMP_CWORD'
+     An index into '${COMP_WORDS}' of the word containing the current
+     cursor position.  This variable is available only in shell
+     functions invoked by the programmable completion facilities (*note
+     Programmable Completion::).
+
+'COMP_LINE'
+     The current command line.  This variable is available only in shell
+     functions and external commands invoked by the programmable
+     completion facilities (*note Programmable Completion::).
+
+'COMP_POINT'
+     The index of the current cursor position relative to the beginning
+     of the current command.  If the current cursor position is at the
+     end of the current command, the value of this variable is equal to
+     '${#COMP_LINE}'.  This variable is available only in shell
+     functions and external commands invoked by the programmable
+     completion facilities (*note Programmable Completion::).
+
+'COMP_TYPE'
+     Set to an integer value corresponding to the type of completion
+     attempted that caused a completion function to be called: <TAB>,
+     for normal completion, '?', for listing completions after
+     successive tabs, '!', for listing alternatives on partial word
+     completion, '@', to list completions if the word is not unmodified,
+     or '%', for menu completion.  This variable is available only in
+     shell functions and external commands invoked by the programmable
+     completion facilities (*note Programmable Completion::).
+
+'COMP_KEY'
+     The key (or final key of a key sequence) used to invoke the current
+     completion function.
+
+'COMP_WORDBREAKS'
+     The set of characters that the Readline library treats as word
+     separators when performing word completion.  If 'COMP_WORDBREAKS'
+     is unset, it loses its special properties, even if it is
+     subsequently reset.
+
+'COMP_WORDS'
+     An array variable consisting of the individual words in the current
+     command line.  The line is split into words as Readline would split
+     it, using 'COMP_WORDBREAKS' as described above.  This variable is
+     available only in shell functions invoked by the programmable
+     completion facilities (*note Programmable Completion::).
+
+'COMPREPLY'
+     An array variable from which Bash reads the possible completions
+     generated by a shell function invoked by the programmable
+     completion facility (*note Programmable Completion::).  Each array
+     element contains one possible completion.
+
+'COPROC'
+     An array variable created to hold the file descriptors for output
+     from and input to an unnamed coprocess (*note Coprocesses::).
+
+'DIRSTACK'
+     An array variable containing the current contents of the directory
+     stack.  Directories appear in the stack in the order they are
+     displayed by the 'dirs' builtin.  Assigning to members of this
+     array variable may be used to modify directories already in the
+     stack, but the 'pushd' and 'popd' builtins must be used to add and
+     remove directories.  Assignment to this variable will not change
+     the current directory.  If 'DIRSTACK' is unset, it loses its
+     special properties, even if it is subsequently reset.
+
+'EMACS'
+     If Bash finds this variable in the environment when the shell
+     starts with value 't', it assumes that the shell is running in an
+     Emacs shell buffer and disables line editing.
+
+'ENV'
+     Expanded and executed similarly to 'BASH_ENV' (*note Bash Startup
+     Files::) when an interactive shell is invoked in POSIX Mode (*note
+     Bash POSIX Mode::).
+
+'EPOCHREALTIME'
+     Each time this parameter is referenced, it expands to the number of
+     seconds since the Unix Epoch as a floating point value with
+     micro-second granularity (see the documentation for the C library
+     function 'time' for the definition of Epoch).  Assignments to
+     'EPOCHREALTIME' are ignored.  If 'EPOCHREALTIME' is unset, it loses
+     its special properties, even if it is subsequently reset.
+
+'EPOCHSECONDS'
+     Each time this parameter is referenced, it expands to the number of
+     seconds since the Unix Epoch (see the documentation for the C
+     library function 'time' for the definition of Epoch).  Assignments
+     to 'EPOCHSECONDS' are ignored.  If 'EPOCHSECONDS' is unset, it
+     loses its special properties, even if it is subsequently reset.
+
+'EUID'
+     The numeric effective user id of the current user.  This variable
+     is readonly.
+
+'EXECIGNORE'
+     A colon-separated list of shell patterns (*note Pattern Matching::)
+     defining the list of filenames to be ignored by command search
+     using 'PATH'.  Files whose full pathnames match one of these
+     patterns are not considered executable files for the purposes of
+     completion and command execution via 'PATH' lookup.  This does not
+     affect the behavior of the '[', 'test', and '[[' commands.  Full
+     pathnames in the command hash table are not subject to
+     'EXECIGNORE'.  Use this variable to ignore shared library files
+     that have the executable bit set, but are not executable files.
+     The pattern matching honors the setting of the 'extglob' shell
+     option.
+
+'FCEDIT'
+     The editor used as a default by the '-e' option to the 'fc' builtin
+     command.
+
+'FIGNORE'
+     A colon-separated list of suffixes to ignore when performing
+     filename completion.  A filename whose suffix matches one of the
+     entries in 'FIGNORE' is excluded from the list of matched
+     filenames.  A sample value is '.o:~'
+
+'FUNCNAME'
+     An array variable containing the names of all shell functions
+     currently in the execution call stack.  The element with index 0 is
+     the name of any currently-executing shell function.  The
+     bottom-most element (the one with the highest index) is '"main"'.
+     This variable exists only when a shell function is executing.
+     Assignments to 'FUNCNAME' have no effect.  If 'FUNCNAME' is unset,
+     it loses its special properties, even if it is subsequently reset.
+
+     This variable can be used with 'BASH_LINENO' and 'BASH_SOURCE'.
+     Each element of 'FUNCNAME' has corresponding elements in
+     'BASH_LINENO' and 'BASH_SOURCE' to describe the call stack.  For
+     instance, '${FUNCNAME[$i]}' was called from the file
+     '${BASH_SOURCE[$i+1]}' at line number '${BASH_LINENO[$i]}'.  The
+     'caller' builtin displays the current call stack using this
+     information.
+
+'FUNCNEST'
+     If set to a numeric value greater than 0, defines a maximum
+     function nesting level.  Function invocations that exceed this
+     nesting level will cause the current command to abort.
+
+'GLOBIGNORE'
+     A colon-separated list of patterns defining the set of file names
+     to be ignored by filename expansion.  If a file name matched by a
+     filename expansion pattern also matches one of the patterns in
+     'GLOBIGNORE', it is removed from the list of matches.  The pattern
+     matching honors the setting of the 'extglob' shell option.
+
+'GROUPS'
+     An array variable containing the list of groups of which the
+     current user is a member.  Assignments to 'GROUPS' have no effect.
+     If 'GROUPS' is unset, it loses its special properties, even if it
+     is subsequently reset.
+
+'histchars'
+     Up to three characters which control history expansion, quick
+     substitution, and tokenization (*note History Interaction::).  The
+     first character is the "history expansion" character, that is, the
+     character which signifies the start of a history expansion,
+     normally '!'.  The second character is the character which
+     signifies 'quick substitution' when seen as the first character on
+     a line, normally '^'.  The optional third character is the
+     character which indicates that the remainder of the line is a
+     comment when found as the first character of a word, usually '#'.
+     The history comment character causes history substitution to be
+     skipped for the remaining words on the line.  It does not
+     necessarily cause the shell parser to treat the rest of the line as
+     a comment.
+
+'HISTCMD'
+     The history number, or index in the history list, of the current
+     command.  Assignments to 'HISTCMD' are ignored.  If 'HISTCMD' is
+     unset, it loses its special properties, even if it is subsequently
+     reset.
+
+'HISTCONTROL'
+     A colon-separated list of values controlling how commands are saved
+     on the history list.  If the list of values includes 'ignorespace',
+     lines which begin with a space character are not saved in the
+     history list.  A value of 'ignoredups' causes lines which match the
+     previous history entry to not be saved.  A value of 'ignoreboth' is
+     shorthand for 'ignorespace' and 'ignoredups'.  A value of
+     'erasedups' causes all previous lines matching the current line to
+     be removed from the history list before that line is saved.  Any
+     value not in the above list is ignored.  If 'HISTCONTROL' is unset,
+     or does not include a valid value, all lines read by the shell
+     parser are saved on the history list, subject to the value of
+     'HISTIGNORE'.  The second and subsequent lines of a multi-line
+     compound command are not tested, and are added to the history
+     regardless of the value of 'HISTCONTROL'.
+
+'HISTFILE'
+     The name of the file to which the command history is saved.  The
+     default value is '~/.bash_history'.
+
+'HISTFILESIZE'
+     The maximum number of lines contained in the history file.  When
+     this variable is assigned a value, the history file is truncated,
+     if necessary, to contain no more than that number of lines by
+     removing the oldest entries.  The history file is also truncated to
+     this size after writing it when a shell exits.  If the value is 0,
+     the history file is truncated to zero size.  Non-numeric values and
+     numeric values less than zero inhibit truncation.  The shell sets
+     the default value to the value of 'HISTSIZE' after reading any
+     startup files.
+
+'HISTIGNORE'
+     A colon-separated list of patterns used to decide which command
+     lines should be saved on the history list.  Each pattern is
+     anchored at the beginning of the line and must match the complete
+     line (no implicit '*' is appended).  Each pattern is tested against
+     the line after the checks specified by 'HISTCONTROL' are applied.
+     In addition to the normal shell pattern matching characters, '&'
+     matches the previous history line.  '&' may be escaped using a
+     backslash; the backslash is removed before attempting a match.  The
+     second and subsequent lines of a multi-line compound command are
+     not tested, and are added to the history regardless of the value of
+     'HISTIGNORE'.  The pattern matching honors the setting of the
+     'extglob' shell option.
+
+     'HISTIGNORE' subsumes the function of 'HISTCONTROL'.  A pattern of
+     '&' is identical to 'ignoredups', and a pattern of '[ ]*' is
+     identical to 'ignorespace'.  Combining these two patterns,
+     separating them with a colon, provides the functionality of
+     'ignoreboth'.
+
+'HISTSIZE'
+     The maximum number of commands to remember on the history list.  If
+     the value is 0, commands are not saved in the history list.
+     Numeric values less than zero result in every command being saved
+     on the history list (there is no limit).  The shell sets the
+     default value to 500 after reading any startup files.
+
+'HISTTIMEFORMAT'
+     If this variable is set and not null, its value is used as a format
+     string for 'strftime' to print the time stamp associated with each
+     history entry displayed by the 'history' builtin.  If this variable
+     is set, time stamps are written to the history file so they may be
+     preserved across shell sessions.  This uses the history comment
+     character to distinguish timestamps from other history lines.
+
+'HOSTFILE'
+     Contains the name of a file in the same format as '/etc/hosts' that
+     should be read when the shell needs to complete a hostname.  The
+     list of possible hostname completions may be changed while the
+     shell is running; the next time hostname completion is attempted
+     after the value is changed, Bash adds the contents of the new file
+     to the existing list.  If 'HOSTFILE' is set, but has no value, or
+     does not name a readable file, Bash attempts to read '/etc/hosts'
+     to obtain the list of possible hostname completions.  When
+     'HOSTFILE' is unset, the hostname list is cleared.
+
+'HOSTNAME'
+     The name of the current host.
+
+'HOSTTYPE'
+     A string describing the machine Bash is running on.
+
+'IGNOREEOF'
+     Controls the action of the shell on receipt of an 'EOF' character
+     as the sole input.  If set, the value denotes the number of
+     consecutive 'EOF' characters that can be read as the first
+     character on an input line before the shell will exit.  If the
+     variable exists but does not have a numeric value, or has no value,
+     then the default is 10.  If the variable does not exist, then 'EOF'
+     signifies the end of input to the shell.  This is only in effect
+     for interactive shells.
+
+'INPUTRC'
+     The name of the Readline initialization file, overriding the
+     default of '~/.inputrc'.
+
+'INSIDE_EMACS'
+     If Bash finds this variable in the environment when the shell
+     starts, it assumes that the shell is running in an Emacs shell
+     buffer and may disable line editing depending on the value of
+     'TERM'.
+
+'LANG'
+     Used to determine the locale category for any category not
+     specifically selected with a variable starting with 'LC_'.
+
+'LC_ALL'
+     This variable overrides the value of 'LANG' and any other 'LC_'
+     variable specifying a locale category.
+
+'LC_COLLATE'
+     This variable determines the collation order used when sorting the
+     results of filename expansion, and determines the behavior of range
+     expressions, equivalence classes, and collating sequences within
+     filename expansion and pattern matching (*note Filename
+     Expansion::).
+
+'LC_CTYPE'
+     This variable determines the interpretation of characters and the
+     behavior of character classes within filename expansion and pattern
+     matching (*note Filename Expansion::).
+
+'LC_MESSAGES'
+     This variable determines the locale used to translate double-quoted
+     strings preceded by a '$' (*note Locale Translation::).
+
+'LC_NUMERIC'
+     This variable determines the locale category used for number
+     formatting.
+
+'LC_TIME'
+     This variable determines the locale category used for data and time
+     formatting.
+
+'LINENO'
+     The line number in the script or shell function currently
+     executing.  If 'LINENO' is unset, it loses its special properties,
+     even if it is subsequently reset.
+
+'LINES'
+     Used by the 'select' command to determine the column length for
+     printing selection lists.  Automatically set if the 'checkwinsize'
+     option is enabled (*note The Shopt Builtin::), or in an interactive
+     shell upon receipt of a 'SIGWINCH'.
+
+'MACHTYPE'
+     A string that fully describes the system type on which Bash is
+     executing, in the standard GNU CPU-COMPANY-SYSTEM format.
+
+'MAILCHECK'
+     How often (in seconds) that the shell should check for mail in the
+     files specified in the 'MAILPATH' or 'MAIL' variables.  The default
+     is 60 seconds.  When it is time to check for mail, the shell does
+     so before displaying the primary prompt.  If this variable is
+     unset, or set to a value that is not a number greater than or equal
+     to zero, the shell disables mail checking.
+
+'MAPFILE'
+     An array variable created to hold the text read by the 'mapfile'
+     builtin when no variable name is supplied.
+
+'OLDPWD'
+     The previous working directory as set by the 'cd' builtin.
+
+'OPTERR'
+     If set to the value 1, Bash displays error messages generated by
+     the 'getopts' builtin command.
+
+'OSTYPE'
+     A string describing the operating system Bash is running on.
+
+'PIPESTATUS'
+     An array variable (*note Arrays::) containing a list of exit status
+     values from the processes in the most-recently-executed foreground
+     pipeline (which may contain only a single command).
+
+'POSIXLY_CORRECT'
+     If this variable is in the environment when Bash starts, the shell
+     enters POSIX mode (*note Bash POSIX Mode::) before reading the
+     startup files, as if the '--posix' invocation option had been
+     supplied.  If it is set while the shell is running, Bash enables
+     POSIX mode, as if the command
+          set -o posix
+     had been executed.  When the shell enters POSIX mode, it sets this
+     variable if it was not already set.
+
+'PPID'
+     The process ID of the shell's parent process.  This variable is
+     readonly.
+
+'PROMPT_COMMAND'
+     If this variable is set, and is an array, the value of each set
+     element is interpreted as a command to execute before printing the
+     primary prompt ('$PS1').  If this is set but not an array variable,
+     its value is used as a command to execute instead.
+
+'PROMPT_DIRTRIM'
+     If set to a number greater than zero, the value is used as the
+     number of trailing directory components to retain when expanding
+     the '\w' and '\W' prompt string escapes (*note Controlling the
+     Prompt::).  Characters removed are replaced with an ellipsis.
+
+'PS0'
+     The value of this parameter is expanded like 'PS1' and displayed by
+     interactive shells after reading a command and before the command
+     is executed.
+
+'PS3'
+     The value of this variable is used as the prompt for the 'select'
+     command.  If this variable is not set, the 'select' command prompts
+     with '#? '
+
+'PS4'
+     The value of this parameter is expanded like 'PS1' and the expanded
+     value is the prompt printed before the command line is echoed when
+     the '-x' option is set (*note The Set Builtin::).  The first
+     character of the expanded value is replicated multiple times, as
+     necessary, to indicate multiple levels of indirection.  The default
+     is '+ '.
+
+'PWD'
+     The current working directory as set by the 'cd' builtin.
+
+'RANDOM'
+     Each time this parameter is referenced, it expands to a random
+     integer between 0 and 32767.  Assigning a value to this variable
+     seeds the random number generator.  If 'RANDOM' is unset, it loses
+     its special properties, even if it is subsequently reset.
+
+'READLINE_ARGUMENT'
+     Any numeric argument given to a Readline command that was defined
+     using 'bind -x' (*note Bash Builtins:: when it was invoked.
+
+'READLINE_LINE'
+     The contents of the Readline line buffer, for use with 'bind -x'
+     (*note Bash Builtins::).
+
+'READLINE_MARK'
+     The position of the "mark" (saved insertion point) in the Readline
+     line buffer, for use with 'bind -x' (*note Bash Builtins::).  The
+     characters between the insertion point and the mark are often
+     called the "region".
+
+'READLINE_POINT'
+     The position of the insertion point in the Readline line buffer,
+     for use with 'bind -x' (*note Bash Builtins::).
+
+'REPLY'
+     The default variable for the 'read' builtin.
+
+'SECONDS'
+     This variable expands to the number of seconds since the shell was
+     started.  Assignment to this variable resets the count to the value
+     assigned, and the expanded value becomes the value assigned plus
+     the number of seconds since the assignment.  The number of seconds
+     at shell invocation and the current time are always determined by
+     querying the system clock.  If 'SECONDS' is unset, it loses its
+     special properties, even if it is subsequently reset.
+
+'SHELL'
+     This environment variable expands to the full pathname to the
+     shell.  If it is not set when the shell starts, Bash assigns to it
+     the full pathname of the current user's login shell.
+
+'SHELLOPTS'
+     A colon-separated list of enabled shell options.  Each word in the
+     list is a valid argument for the '-o' option to the 'set' builtin
+     command (*note The Set Builtin::).  The options appearing in
+     'SHELLOPTS' are those reported as 'on' by 'set -o'.  If this
+     variable is in the environment when Bash starts up, each shell
+     option in the list will be enabled before reading any startup
+     files.  This variable is readonly.
+
+'SHLVL'
+     Incremented by one each time a new instance of Bash is started.
+     This is intended to be a count of how deeply your Bash shells are
+     nested.
+
+'SRANDOM'
+     This variable expands to a 32-bit pseudo-random number each time it
+     is referenced.  The random number generator is not linear on
+     systems that support '/dev/urandom' or 'arc4random', so each
+     returned number has no relationship to the numbers preceding it.
+     The random number generator cannot be seeded, so assignments to
+     this variable have no effect.  If 'SRANDOM' is unset, it loses its
+     special properties, even if it is subsequently reset.
+
+'TIMEFORMAT'
+     The value of this parameter is used as a format string specifying
+     how the timing information for pipelines prefixed with the 'time'
+     reserved word should be displayed.  The '%' character introduces an
+     escape sequence that is expanded to a time value or other
+     information.  The escape sequences and their meanings are as
+     follows; the braces denote optional portions.
+
+     '%%'
+          A literal '%'.
+
+     '%[P][l]R'
+          The elapsed time in seconds.
+
+     '%[P][l]U'
+          The number of CPU seconds spent in user mode.
+
+     '%[P][l]S'
+          The number of CPU seconds spent in system mode.
+
+     '%P'
+          The CPU percentage, computed as (%U + %S) / %R.
+
+     The optional P is a digit specifying the precision, the number of
+     fractional digits after a decimal point.  A value of 0 causes no
+     decimal point or fraction to be output.  At most three places after
+     the decimal point may be specified; values of P greater than 3 are
+     changed to 3.  If P is not specified, the value 3 is used.
+
+     The optional 'l' specifies a longer format, including minutes, of
+     the form MMmSS.FFs.  The value of P determines whether or not the
+     fraction is included.
+
+     If this variable is not set, Bash acts as if it had the value
+          $'\nreal\t%3lR\nuser\t%3lU\nsys\t%3lS'
+     If the value is null, no timing information is displayed.  A
+     trailing newline is added when the format string is displayed.
+
+'TMOUT'
+     If set to a value greater than zero, 'TMOUT' is treated as the
+     default timeout for the 'read' builtin (*note Bash Builtins::).
+     The 'select' command (*note Conditional Constructs::) terminates if
+     input does not arrive after 'TMOUT' seconds when input is coming
+     from a terminal.
+
+     In an interactive shell, the value is interpreted as the number of
+     seconds to wait for a line of input after issuing the primary
+     prompt.  Bash terminates after waiting for that number of seconds
+     if a complete line of input does not arrive.
+
+'TMPDIR'
+     If set, Bash uses its value as the name of a directory in which
+     Bash creates temporary files for the shell's use.
+
+'UID'
+     The numeric real user id of the current user.  This variable is
+     readonly.

+
+6.1 Invoking Bash
+=================
+
+     bash [long-opt] [-ir] [-abefhkmnptuvxdBCDHP] [-o OPTION]
+         [-O SHOPT_OPTION] [ARGUMENT ...]
+     bash [long-opt] [-abefhkmnptuvxdBCDHP] [-o OPTION]
+         [-O SHOPT_OPTION] -c STRING [ARGUMENT ...]
+     bash [long-opt] -s [-abefhkmnptuvxdBCDHP] [-o OPTION]
+         [-O SHOPT_OPTION] [ARGUMENT ...]
+
+   All of the single-character options used with the 'set' builtin
+(*note The Set Builtin::) can be used as options when the shell is
+invoked.  In addition, there are several multi-character options that
+you can use.  These options must appear on the command line before the
+single-character options to be recognized.
+
+'--debugger'
+     Arrange for the debugger profile to be executed before the shell
+     starts.  Turns on extended debugging mode (see *note The Shopt
+     Builtin:: for a description of the 'extdebug' option to the 'shopt'
+     builtin).
+
+'--dump-po-strings'
+     A list of all double-quoted strings preceded by '$' is printed on
+     the standard output in the GNU 'gettext' PO (portable object) file
+     format.  Equivalent to '-D' except for the output format.
+
+'--dump-strings'
+     Equivalent to '-D'.
+
+'--help'
+     Display a usage message on standard output and exit successfully.
+
+'--init-file FILENAME'
+'--rcfile FILENAME'
+     Execute commands from FILENAME (instead of '~/.bashrc') in an
+     interactive shell.
+
+'--login'
+     Equivalent to '-l'.
+
+'--noediting'
+     Do not use the GNU Readline library (*note Command Line Editing::)
+     to read command lines when the shell is interactive.
+
+'--noprofile'
+     Don't load the system-wide startup file '/etc/profile' or any of
+     the personal initialization files '~/.bash_profile',
+     '~/.bash_login', or '~/.profile' when Bash is invoked as a login
+     shell.
+
+'--norc'
+     Don't read the '~/.bashrc' initialization file in an interactive
+     shell.  This is on by default if the shell is invoked as 'sh'.
+
+'--posix'
+     Change the behavior of Bash where the default operation differs
+     from the POSIX standard to match the standard.  This is intended to
+     make Bash behave as a strict superset of that standard.  *Note Bash
+     POSIX Mode::, for a description of the Bash POSIX mode.
+
+'--restricted'
+     Make the shell a restricted shell (*note The Restricted Shell::).
+
+'--verbose'
+     Equivalent to '-v'.  Print shell input lines as they're read.
+
+'--version'
+     Show version information for this instance of Bash on the standard
+     output and exit successfully.
+
+   There are several single-character options that may be supplied at
+invocation which are not available with the 'set' builtin.
+
+'-c'
+     Read and execute commands from the first non-option argument
+     COMMAND_STRING, then exit.  If there are arguments after the
+     COMMAND_STRING, the first argument is assigned to '$0' and any
+     remaining arguments are assigned to the positional parameters.  The
+     assignment to '$0' sets the name of the shell, which is used in
+     warning and error messages.
+
+'-i'
+     Force the shell to run interactively.  Interactive shells are
+     described in *note Interactive Shells::.
+
+'-l'
+     Make this shell act as if it had been directly invoked by login.
+     When the shell is interactive, this is equivalent to starting a
+     login shell with 'exec -l bash'.  When the shell is not
+     interactive, the login shell startup files will be executed.  'exec
+     bash -l' or 'exec bash --login' will replace the current shell with
+     a Bash login shell.  *Note Bash Startup Files::, for a description
+     of the special behavior of a login shell.
+
+'-r'
+     Make the shell a restricted shell (*note The Restricted Shell::).
+
+'-s'
+     If this option is present, or if no arguments remain after option
+     processing, then commands are read from the standard input.  This
+     option allows the positional parameters to be set when invoking an
+     interactive shell or when reading input through a pipe.
+
+'-D'
+     A list of all double-quoted strings preceded by '$' is printed on
+     the standard output.  These are the strings that are subject to
+     language translation when the current locale is not 'C' or 'POSIX'
+     (*note Locale Translation::).  This implies the '-n' option; no
+     commands will be executed.
+
+'[-+]O [SHOPT_OPTION]'
+     SHOPT_OPTION is one of the shell options accepted by the 'shopt'
+     builtin (*note The Shopt Builtin::).  If SHOPT_OPTION is present,
+     '-O' sets the value of that option; '+O' unsets it.  If
+     SHOPT_OPTION is not supplied, the names and values of the shell
+     options accepted by 'shopt' are printed on the standard output.  If
+     the invocation option is '+O', the output is displayed in a format
+     that may be reused as input.
+
+'--'
+     A '--' signals the end of options and disables further option
+     processing.  Any arguments after the '--' are treated as filenames
+     and arguments.
+
+   A _login_ shell is one whose first character of argument zero is '-',
+or one invoked with the '--login' option.
+
+   An _interactive_ shell is one started without non-option arguments,
+unless '-s' is specified, without specifying the '-c' option, and whose
+input and output are both connected to terminals (as determined by
+'isatty(3)'), or one started with the '-i' option.  *Note Interactive
+Shells::, for more information.
+
+   If arguments remain after option processing, and neither the '-c' nor
+the '-s' option has been supplied, the first argument is assumed to be
+the name of a file containing shell commands (*note Shell Scripts::).
+When Bash is invoked in this fashion, '$0' is set to the name of the
+file, and the positional parameters are set to the remaining arguments.
+Bash reads and executes commands from this file, then exits.  Bash's
+exit status is the exit status of the last command executed in the
+script.  If no commands are executed, the exit status is 0.

+6.2 Bash Startup Files
+======================
+
+This section describes how Bash executes its startup files.  If any of
+the files exist but cannot be read, Bash reports an error.  Tildes are
+expanded in filenames as described above under Tilde Expansion (*note
+Tilde Expansion::).
+
+   Interactive shells are described in *note Interactive Shells::.
+
+Invoked as an interactive login shell, or with '--login'
+........................................................
+
+When Bash is invoked as an interactive login shell, or as a
+non-interactive shell with the '--login' option, it first reads and
+executes commands from the file '/etc/profile', if that file exists.
+After reading that file, it looks for '~/.bash_profile',
+'~/.bash_login', and '~/.profile', in that order, and reads and executes
+commands from the first one that exists and is readable.  The
+'--noprofile' option may be used when the shell is started to inhibit
+this behavior.
+
+   When an interactive login shell exits, or a non-interactive login
+shell executes the 'exit' builtin command, Bash reads and executes
+commands from the file '~/.bash_logout', if it exists.
+
+Invoked as an interactive non-login shell
+.........................................
+
+When an interactive shell that is not a login shell is started, Bash
+reads and executes commands from '~/.bashrc', if that file exists.  This
+may be inhibited by using the '--norc' option.  The '--rcfile FILE'
+option will force Bash to read and execute commands from FILE instead of
+'~/.bashrc'.
+
+   So, typically, your '~/.bash_profile' contains the line
+     if [ -f ~/.bashrc ]; then . ~/.bashrc; fi
+after (or before) any login-specific initializations.
+
+Invoked non-interactively
+.........................
+
+When Bash is started non-interactively, to run a shell script, for
+example, it looks for the variable 'BASH_ENV' in the environment,
+expands its value if it appears there, and uses the expanded value as
+the name of a file to read and execute.  Bash behaves as if the
+following command were executed:
+     if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi
+but the value of the 'PATH' variable is not used to search for the
+filename.
+
+   As noted above, if a non-interactive shell is invoked with the
+'--login' option, Bash attempts to read and execute commands from the
+login shell startup files.
+
+Invoked with name 'sh'
+......................
+
+If Bash is invoked with the name 'sh', it tries to mimic the startup
+behavior of historical versions of 'sh' as closely as possible, while
+conforming to the POSIX standard as well.
+
+   When invoked as an interactive login shell, or as a non-interactive
+shell with the '--login' option, it first attempts to read and execute
+commands from '/etc/profile' and '~/.profile', in that order.  The
+'--noprofile' option may be used to inhibit this behavior.  When invoked
+as an interactive shell with the name 'sh', Bash looks for the variable
+'ENV', expands its value if it is defined, and uses the expanded value
+as the name of a file to read and execute.  Since a shell invoked as
+'sh' does not attempt to read and execute commands from any other
+startup files, the '--rcfile' option has no effect.  A non-interactive
+shell invoked with the name 'sh' does not attempt to read any other
+startup files.
+
+   When invoked as 'sh', Bash enters POSIX mode after the startup files
+are read.
+
+Invoked in POSIX mode
+.....................
+
+When Bash is started in POSIX mode, as with the '--posix' command line
+option, it follows the POSIX standard for startup files.  In this mode,
+interactive shells expand the 'ENV' variable and commands are read and
+executed from the file whose name is the expanded value.  No other
+startup files are read.
+
+Invoked by remote shell daemon
+..............................
+
+Bash attempts to determine when it is being run with its standard input
+connected to a network connection, as when executed by the historical
+remote shell daemon, usually 'rshd', or the secure shell daemon 'sshd'.
+If Bash determines it is being run non-interactively in this fashion, it
+reads and executes commands from '~/.bashrc', if that file exists and is
+readable.  It will not do this if invoked as 'sh'.  The '--norc' option
+may be used to inhibit this behavior, and the '--rcfile' option may be
+used to force another file to be read, but neither 'rshd' nor 'sshd'
+generally invoke the shell with those options or allow them to be
+specified.
+
+Invoked with unequal effective and real UID/GIDs
+................................................
+
+If Bash is started with the effective user (group) id not equal to the
+real user (group) id, and the '-p' option is not supplied, no startup
+files are read, shell functions are not inherited from the environment,
+the 'SHELLOPTS', 'BASHOPTS', 'CDPATH', and 'GLOBIGNORE' variables, if
+they appear in the environment, are ignored, and the effective user id
+is set to the real user id.  If the '-p' option is supplied at
+invocation, the startup behavior is the same, but the effective user id
+is not reset.

+
+6.3.1 What is an Interactive Shell?
+-----------------------------------
+
+An interactive shell is one started without non-option arguments (unless
+'-s' is specified) and without specifying the '-c' option, whose input
+and error output are both connected to terminals (as determined by
+'isatty(3)'), or one started with the '-i' option.
+
+   An interactive shell generally reads from and writes to a user's
+terminal.
+
+   The '-s' invocation option may be used to set the positional
+parameters when an interactive shell is started.
+
+
+File: bash.info,  Node: Is this Shell Interactive?,  Next: Interactive Shell Behavior,  Prev: What is an Interactive Shell?,  Up: Interactive Shells
+
+6.3.2 Is this Shell Interactive?
+--------------------------------
+
+To determine within a startup script whether or not Bash is running
+interactively, test the value of the '-' special parameter.  It contains
+'i' when the shell is interactive.  For example:
+
+     case "$-" in
+     *i*)	echo This shell is interactive ;;
+     *)	echo This shell is not interactive ;;
+     esac
+
+   Alternatively, startup scripts may examine the variable 'PS1'; it is
+unset in non-interactive shells, and set in interactive shells.  Thus:
+
+     if [ -z "$PS1" ]; then
+             echo This shell is not interactive
+     else
+             echo This shell is interactive
+     fi
+
+
+File: bash.info,  Node: Interactive Shell Behavior,  Prev: Is this Shell Interactive?,  Up: Interactive Shells
+
+6.3.3 Interactive Shell Behavior
+--------------------------------
+
+When the shell is running interactively, it changes its behavior in
+several ways.
+
+  1. Startup files are read and executed as described in *note Bash
+     Startup Files::.
+
+  2. Job Control (*note Job Control::) is enabled by default.  When job
+     control is in effect, Bash ignores the keyboard-generated job
+     control signals 'SIGTTIN', 'SIGTTOU', and 'SIGTSTP'.
+
+  3. Bash expands and displays 'PS1' before reading the first line of a
+     command, and expands and displays 'PS2' before reading the second
+     and subsequent lines of a multi-line command.  Bash expands and
+     displays 'PS0' after it reads a command but before executing it.
+     See *note Controlling the Prompt::, for a complete list of prompt
+     string escape sequences.
+
+  4. Bash executes the values of the set elements of the
+     'PROMPT_COMMAND' array variable as commands before printing the
+     primary prompt, '$PS1' (*note Bash Variables::).
+
+  5. Readline (*note Command Line Editing::) is used to read commands
+     from the user's terminal.
+
+  6. Bash inspects the value of the 'ignoreeof' option to 'set -o'
+     instead of exiting immediately when it receives an 'EOF' on its
+     standard input when reading a command (*note The Set Builtin::).
+
+  7. Command history (*note Bash History Facilities::) and history
+     expansion (*note History Interaction::) are enabled by default.
+     Bash will save the command history to the file named by '$HISTFILE'
+     when a shell with history enabled exits.
+
+  8. Alias expansion (*note Aliases::) is performed by default.
+
+  9. In the absence of any traps, Bash ignores 'SIGTERM' (*note
+     Signals::).
+
+  10. In the absence of any traps, 'SIGINT' is caught and handled (*note
+     Signals::).  'SIGINT' will interrupt some shell builtins.
+
+  11. An interactive login shell sends a 'SIGHUP' to all jobs on exit if
+     the 'huponexit' shell option has been enabled (*note Signals::).
+
+  12. The '-n' invocation option is ignored, and 'set -n' has no effect
+     (*note The Set Builtin::).
+
+  13. Bash will check for mail periodically, depending on the values of
+     the 'MAIL', 'MAILPATH', and 'MAILCHECK' shell variables (*note Bash
+     Variables::).
+
+  14. Expansion errors due to references to unbound shell variables
+     after 'set -u' has been enabled will not cause the shell to exit
+     (*note The Set Builtin::).
+
+  15. The shell will not exit on expansion errors caused by VAR being
+     unset or null in '${VAR:?WORD}' expansions (*note Shell Parameter
+     Expansion::).
+
+  16. Redirection errors encountered by shell builtins will not cause
+     the shell to exit.
+
+  17. When running in POSIX mode, a special builtin returning an error
+     status will not cause the shell to exit (*note Bash POSIX Mode::).
+
+  18. A failed 'exec' will not cause the shell to exit (*note Bourne
+     Shell Builtins::).
+
+  19. Parser syntax errors will not cause the shell to exit.
+
+  20. If the 'cdspell' shell option is enabled, the shell will attempt
+     simple spelling correction for directory arguments to the 'cd'
+     builtin (see the description of the 'cdspell' option to the 'shopt'
+     builtin in *note The Shopt Builtin::).  The 'cdspell' option is
+     only effective in interactive shells.
+
+  21. The shell will check the value of the 'TMOUT' variable and exit if
+     a command is not read within the specified number of seconds after
+     printing '$PS1' (*note Bash Variables::).
+

+
+6.4 Bash Conditional Expressions
+================================
+
+Conditional expressions are used by the '[[' compound command (*note
+Conditional Constructs::) and the 'test' and '[' builtin commands (*note
+Bourne Shell Builtins::).  The 'test' and '[' commands determine their
+behavior based on the number of arguments; see the descriptions of those
+commands for any other command-specific actions.
+
+   Expressions may be unary or binary, and are formed from the following
+primaries.  Unary expressions are often used to examine the status of a
+file.  There are string operators and numeric comparison operators as
+well.  Bash handles several filenames specially when they are used in
+expressions.  If the operating system on which Bash is running provides
+these special files, Bash will use them; otherwise it will emulate them
+internally with this behavior: If the FILE argument to one of the
+primaries is of the form '/dev/fd/N', then file descriptor N is checked.
+If the FILE argument to one of the primaries is one of '/dev/stdin',
+'/dev/stdout', or '/dev/stderr', file descriptor 0, 1, or 2,
+respectively, is checked.
+
+   When used with '[[', the '<' and '>' operators sort lexicographically
+using the current locale.  The 'test' command uses ASCII ordering.
+
+   Unless otherwise specified, primaries that operate on files follow
+symbolic links and operate on the target of the link, rather than the
+link itself.
+
+'-a FILE'
+     True if FILE exists.
+
+'-b FILE'
+     True if FILE exists and is a block special file.
+
+'-c FILE'
+     True if FILE exists and is a character special file.
+
+'-d FILE'
+     True if FILE exists and is a directory.
+
+'-e FILE'
+     True if FILE exists.
+
+'-f FILE'
+     True if FILE exists and is a regular file.
+
+'-g FILE'
+     True if FILE exists and its set-group-id bit is set.
+
+'-h FILE'
+     True if FILE exists and is a symbolic link.
+
+'-k FILE'
+     True if FILE exists and its "sticky" bit is set.
+
+'-p FILE'
+     True if FILE exists and is a named pipe (FIFO).
+
+'-r FILE'
+     True if FILE exists and is readable.
+
+'-s FILE'
+     True if FILE exists and has a size greater than zero.
+
+'-t FD'
+     True if file descriptor FD is open and refers to a terminal.
+
+'-u FILE'
+     True if FILE exists and its set-user-id bit is set.
+
+'-w FILE'
+     True if FILE exists and is writable.
+
+'-x FILE'
+     True if FILE exists and is executable.
+
+'-G FILE'
+     True if FILE exists and is owned by the effective group id.
+
+'-L FILE'
+     True if FILE exists and is a symbolic link.
+
+'-N FILE'
+     True if FILE exists and has been modified since it was last read.
+
+'-O FILE'
+     True if FILE exists and is owned by the effective user id.
+
+'-S FILE'
+     True if FILE exists and is a socket.
+
+'FILE1 -ef FILE2'
+     True if FILE1 and FILE2 refer to the same device and inode numbers.
+
+'FILE1 -nt FILE2'
+     True if FILE1 is newer (according to modification date) than FILE2,
+     or if FILE1 exists and FILE2 does not.
+
+'FILE1 -ot FILE2'
+     True if FILE1 is older than FILE2, or if FILE2 exists and FILE1
+     does not.
+
+'-o OPTNAME'
+     True if the shell option OPTNAME is enabled.  The list of options
+     appears in the description of the '-o' option to the 'set' builtin
+     (*note The Set Builtin::).
+
+'-v VARNAME'
+     True if the shell variable VARNAME is set (has been assigned a
+     value).
+
+'-R VARNAME'
+     True if the shell variable VARNAME is set and is a name reference.
+
+'-z STRING'
+     True if the length of STRING is zero.
+
+'-n STRING'
+'STRING'
+     True if the length of STRING is non-zero.
+
+'STRING1 == STRING2'
+'STRING1 = STRING2'
+     True if the strings are equal.  When used with the '[[' command,
+     this performs pattern matching as described above (*note
+     Conditional Constructs::).
+
+     '=' should be used with the 'test' command for POSIX conformance.
+
+'STRING1 != STRING2'
+     True if the strings are not equal.
+
+'STRING1 < STRING2'
+     True if STRING1 sorts before STRING2 lexicographically.
+
+'STRING1 > STRING2'
+     True if STRING1 sorts after STRING2 lexicographically.
+
+'ARG1 OP ARG2'
+     'OP' is one of '-eq', '-ne', '-lt', '-le', '-gt', or '-ge'.  These
+     arithmetic binary operators return true if ARG1 is equal to, not
+     equal to, less than, less than or equal to, greater than, or
+     greater than or equal to ARG2, respectively.  ARG1 and ARG2 may be
+     positive or negative integers.  When used with the '[[' command,
+     ARG1 and ARG2 are evaluated as arithmetic expressions (*note Shell
+     Arithmetic::).
+
+
+File: bash.info,  Node: Shell Arithmetic,  Next: Aliases,  Prev: Bash Conditional Expressions,  Up: Bash Features
+
+6.5 Shell Arithmetic
+====================
+
+The shell allows arithmetic expressions to be evaluated, as one of the
+shell expansions or by using the '((' compound command, the 'let'
+builtin, or the '-i' option to the 'declare' builtin.
+
+   Evaluation is done in fixed-width integers with no check for
+overflow, though division by 0 is trapped and flagged as an error.  The
+operators and their precedence, associativity, and values are the same
+as in the C language.  The following list of operators is grouped into
+levels of equal-precedence operators.  The levels are listed in order of
+decreasing precedence.
+
+'ID++ ID--'
+     variable post-increment and post-decrement
+
+'++ID --ID'
+     variable pre-increment and pre-decrement
+
+'- +'
+     unary minus and plus
+
+'! ~'
+     logical and bitwise negation
+
+'**'
+     exponentiation
+
+'* / %'
+     multiplication, division, remainder
+
+'+ -'
+     addition, subtraction
+
+'<< >>'
+     left and right bitwise shifts
+
+'<= >= < >'
+     comparison
+
+'== !='
+     equality and inequality
+
+'&'
+     bitwise AND
+
+'^'
+     bitwise exclusive OR
+
+'|'
+     bitwise OR
+
+'&&'
+     logical AND
+
+'||'
+     logical OR
+
+'expr ? expr : expr'
+     conditional operator
+
+'= *= /= %= += -= <<= >>= &= ^= |='
+     assignment
+
+'expr1 , expr2'
+     comma
+
+   Shell variables are allowed as operands; parameter expansion is
+performed before the expression is evaluated.  Within an expression,
+shell variables may also be referenced by name without using the
+parameter expansion syntax.  A shell variable that is null or unset
+evaluates to 0 when referenced by name without using the parameter
+expansion syntax.  The value of a variable is evaluated as an arithmetic
+expression when it is referenced, or when a variable which has been
+given the 'integer' attribute using 'declare -i' is assigned a value.  A
+null value evaluates to 0.  A shell variable need not have its 'integer'
+attribute turned on to be used in an expression.
+
+   Integer constants follow the C language definition, without suffixes
+or character constants.  Constants with a leading 0 are interpreted as
+octal numbers.  A leading '0x' or '0X' denotes hexadecimal.  Otherwise,
+numbers take the form [BASE'#']N, where the optional BASE is a decimal
+number between 2 and 64 representing the arithmetic base, and N is a
+number in that base.  If BASE'#' is omitted, then base 10 is used.  When
+specifying N, if a non-digit is required, the digits greater than 9 are
+represented by the lowercase letters, the uppercase letters, '@', and
+'_', in that order.  If BASE is less than or equal to 36, lowercase and
+uppercase letters may be used interchangeably to represent numbers
+between 10 and 35.
+
+   Operators are evaluated in order of precedence.  Sub-expressions in
+parentheses are evaluated first and may override the precedence rules
+above.
+
+
+File: bash.info,  Node: Aliases,  Next: Arrays,  Prev: Shell Arithmetic,  Up: Bash Features
+
+6.6 Aliases
+===========
+
+"Aliases" allow a string to be substituted for a word when it is used as
+the first word of a simple command.  The shell maintains a list of
+aliases that may be set and unset with the 'alias' and 'unalias' builtin
+commands.
+
+   The first word of each simple command, if unquoted, is checked to see
+if it has an alias.  If so, that word is replaced by the text of the
+alias.  The characters '/', '$', '`', '=' and any of the shell
+metacharacters or quoting characters listed above may not appear in an
+alias name.  The replacement text may contain any valid shell input,
+including shell metacharacters.  The first word of the replacement text
+is tested for aliases, but a word that is identical to an alias being
+expanded is not expanded a second time.  This means that one may alias
+'ls' to '"ls -F"', for instance, and Bash does not try to recursively
+expand the replacement text.  If the last character of the alias value
+is a 'blank', then the next command word following the alias is also
+checked for alias expansion.
+
+   Aliases are created and listed with the 'alias' command, and removed
+with the 'unalias' command.
+
+   There is no mechanism for using arguments in the replacement text, as
+in 'csh'.  If arguments are needed, use a shell function (*note Shell
+Functions::).
+
+   Aliases are not expanded when the shell is not interactive, unless
+the 'expand_aliases' shell option is set using 'shopt' (*note The Shopt
+Builtin::).
+
+   The rules concerning the definition and use of aliases are somewhat
+confusing.  Bash always reads at least one complete line of input, and
+all lines that make up a compound command, before executing any of the
+commands on that line or the compound command.  Aliases are expanded
+when a command is read, not when it is executed.  Therefore, an alias
+definition appearing on the same line as another command does not take
+effect until the next line of input is read.  The commands following the
+alias definition on that line are not affected by the new alias.  This
+behavior is also an issue when functions are executed.  Aliases are
+expanded when a function definition is read, not when the function is
+executed, because a function definition is itself a command.  As a
+consequence, aliases defined in a function are not available until after
+that function is executed.  To be safe, always put alias definitions on
+a separate line, and do not use 'alias' in compound commands.
+
+   For almost every purpose, shell functions are preferred over aliases.
+

+
+6.7 Arrays
+==========
+
+Bash provides one-dimensional indexed and associative array variables.
+Any variable may be used as an indexed array; the 'declare' builtin will
+explicitly declare an array.  There is no maximum limit on the size of
+an array, nor any requirement that members be indexed or assigned
+contiguously.  Indexed arrays are referenced using integers (including
+arithmetic expressions (*note Shell Arithmetic::)) and are zero-based;
+associative arrays use arbitrary strings.  Unless otherwise noted,
+indexed array indices must be non-negative integers.
+
+   An indexed array is created automatically if any variable is assigned
+to using the syntax
+     NAME[SUBSCRIPT]=VALUE
+
+The SUBSCRIPT is treated as an arithmetic expression that must evaluate
+to a number.  To explicitly declare an array, use
+     declare -a NAME
+The syntax
+     declare -a NAME[SUBSCRIPT]
+is also accepted; the SUBSCRIPT is ignored.
+
+Associative arrays are created using
+     declare -A NAME
+
+   Attributes may be specified for an array variable using the 'declare'
+and 'readonly' builtins.  Each attribute applies to all members of an
+array.
+
+   Arrays are assigned to using compound assignments of the form
+     NAME=(VALUE1 VALUE2 ... )
+where each VALUE may be of the form '[SUBSCRIPT]='STRING.  Indexed array
+assignments do not require anything but STRING.  When assigning to
+indexed arrays, if the optional subscript is supplied, that index is
+assigned to; otherwise the index of the element assigned is the last
+index assigned to by the statement plus one.  Indexing starts at zero.
+
+   Each VALUE in the list undergoes all the shell expansions described
+above (*note Shell Expansions::).
+
+   When assigning to an associative array, the words in a compound
+assignment may be either assignment statements, for which the subscript
+is required, or a list of words that is interpreted as a sequence of
+alternating keys and values: NAME=(KEY1 VALUE1 KEY2 VALUE2 ... ).  These
+are treated identically to NAME=( [KEY1]=VALUE1 [KEY2]=VALUE2 ... ).
+The first word in the list determines how the remaining words are
+interpreted; all assignments in a list must be of the same type.  When
+using key/value pairs, the keys may not be missing or empty; a final
+missing value is treated like the empty string.
+
+   This syntax is also accepted by the 'declare' builtin.  Individual
+array elements may be assigned to using the 'NAME[SUBSCRIPT]=VALUE'
+syntax introduced above.
+
+   When assigning to an indexed array, if NAME is subscripted by a
+negative number, that number is interpreted as relative to one greater
+than the maximum index of NAME, so negative indices count back from the
+end of the array, and an index of -1 references the last element.
+
+   The '+=' operator will append to an array variable when assigning
+using the compound assignment syntax; see *note Shell Parameters::
+above.
+
+   Any element of an array may be referenced using '${NAME[SUBSCRIPT]}'.
+The braces are required to avoid conflicts with the shell's filename
+expansion operators.  If the SUBSCRIPT is '@' or '*', the word expands
+to all members of the array NAME.  These subscripts differ only when the
+word appears within double quotes.  If the word is double-quoted,
+'${NAME[*]}' expands to a single word with the value of each array
+member separated by the first character of the 'IFS' variable, and
+'${NAME[@]}' expands each element of NAME to a separate word.  When
+there are no array members, '${NAME[@]}' expands to nothing.  If the
+double-quoted expansion occurs within a word, the expansion of the first
+parameter is joined with the beginning part of the original word, and
+the expansion of the last parameter is joined with the last part of the
+original word.  This is analogous to the expansion of the special
+parameters '@' and '*'.  '${#NAME[SUBSCRIPT]}' expands to the length of
+'${NAME[SUBSCRIPT]}'.  If SUBSCRIPT is '@' or '*', the expansion is the
+number of elements in the array.  If the SUBSCRIPT used to reference an
+element of an indexed array evaluates to a number less than zero, it is
+interpreted as relative to one greater than the maximum index of the
+array, so negative indices count back from the end of the array, and an
+index of -1 refers to the last element.
+
+   Referencing an array variable without a subscript is equivalent to
+referencing with a subscript of 0.  Any reference to a variable using a
+valid subscript is legal, and 'bash' will create an array if necessary.
+
+   An array variable is considered set if a subscript has been assigned
+a value.  The null string is a valid value.
+
+   It is possible to obtain the keys (indices) of an array as well as
+the values.  ${!NAME[@]} and ${!NAME[*]} expand to the indices assigned
+in array variable NAME.  The treatment when in double quotes is similar
+to the expansion of the special parameters '@' and '*' within double
+quotes.
+
+   The 'unset' builtin is used to destroy arrays.  'unset
+NAME[SUBSCRIPT]' destroys the array element at index SUBSCRIPT.
+Negative subscripts to indexed arrays are interpreted as described
+above.  Unsetting the last element of an array variable does not unset
+the variable.  'unset NAME', where NAME is an array, removes the entire
+array.  'unset NAME[SUBSCRIPT]' behaves differently depending on the
+array type when given a subscript of '*' or '@'.  When NAME is an
+associative array, it removes the element with key '*' or '@'.  If NAME
+is an indexed array, 'unset' removes all of the elements, but does not
+remove the array itself.
+
+   When using a variable name with a subscript as an argument to a
+command, such as with 'unset', without using the word expansion syntax
+described above, the argument is subject to the shell's filename
+expansion.  If filename expansion is not desired, the argument should be
+quoted.
+
+   The 'declare', 'local', and 'readonly' builtins each accept a '-a'
+option to specify an indexed array and a '-A' option to specify an
+associative array.  If both options are supplied, '-A' takes precedence.
+The 'read' builtin accepts a '-a' option to assign a list of words read
+from the standard input to an array, and can read values from the
+standard input into individual array elements.  The 'set' and 'declare'
+builtins display array values in a way that allows them to be reused as
+input.

+6.8 The Directory Stack
+=======================
+
+* Menu:
+
+* Directory Stack Builtins::		Bash builtin commands to manipulate
+					the directory stack.
+
+The directory stack is a list of recently-visited directories.  The
+'pushd' builtin adds directories to the stack as it changes the current
+directory, and the 'popd' builtin removes specified directories from the
+stack and changes the current directory to the directory removed.  The
+'dirs' builtin displays the contents of the directory stack.  The
+current directory is always the "top" of the directory stack.
+
+   The contents of the directory stack are also visible as the value of
+the 'DIRSTACK' shell variable.
+
+
+File: bash.info,  Node: Directory Stack Builtins,  Up: The Directory Stack
+
+6.8.1 Directory Stack Builtins
+------------------------------
+
+'dirs'
+          dirs [-clpv] [+N | -N]
+
+     Display the list of currently remembered directories.  Directories
+     are added to the list with the 'pushd' command; the 'popd' command
+     removes directories from the list.  The current directory is always
+     the first directory in the stack.
+
+     '-c'
+          Clears the directory stack by deleting all of the elements.
+     '-l'
+          Produces a listing using full pathnames; the default listing
+          format uses a tilde to denote the home directory.
+     '-p'
+          Causes 'dirs' to print the directory stack with one entry per
+          line.
+     '-v'
+          Causes 'dirs' to print the directory stack with one entry per
+          line, prefixing each entry with its index in the stack.
+     '+N'
+          Displays the Nth directory (counting from the left of the list
+          printed by 'dirs' when invoked without options), starting with
+          zero.
+     '-N'
+          Displays the Nth directory (counting from the right of the
+          list printed by 'dirs' when invoked without options), starting
+          with zero.
+
+'popd'
+          popd [-n] [+N | -N]
+
+     Removes elements from the directory stack.  The elements are
+     numbered from 0 starting at the first directory listed by 'dirs';
+     that is, 'popd' is equivalent to 'popd +0'.
+
+     When no arguments are given, 'popd' removes the top directory from
+     the stack and changes to the new top directory.
+
+     Arguments, if supplied, have the following meanings:
+
+     '-n'
+          Suppresses the normal change of directory when removing
+          directories from the stack, so that only the stack is
+          manipulated.
+     '+N'
+          Removes the Nth directory (counting from the left of the list
+          printed by 'dirs'), starting with zero, from the stack.
+     '-N'
+          Removes the Nth directory (counting from the right of the list
+          printed by 'dirs'), starting with zero, from the stack.
+
+     If the top element of the directory stack is modified, and the '-n'
+     option was not supplied, 'popd' uses the 'cd' builtin to change to
+     the directory at the top of the stack.  If the 'cd' fails, 'popd'
+     returns a non-zero value.
+
+     Otherwise, 'popd' returns an unsuccessful status if an invalid
+     option is encountered, the directory stack is empty, or a
+     non-existent directory stack entry is specified.
+
+     If the 'popd' command is successful, Bash runs 'dirs' to show the
+     final contents of the directory stack, and the return status is 0.
+
+'pushd'
+          pushd [-n] [+N | -N | DIR]
+
+     Adds a directory to the top of the directory stack, or rotates the
+     stack, making the new top of the stack the current working
+     directory.  With no arguments, 'pushd' exchanges the top two
+     elements of the directory stack.
+
+     Arguments, if supplied, have the following meanings:
+
+     '-n'
+          Suppresses the normal change of directory when rotating or
+          adding directories to the stack, so that only the stack is
+          manipulated.
+     '+N'
+          Brings the Nth directory (counting from the left of the list
+          printed by 'dirs', starting with zero) to the top of the list
+          by rotating the stack.
+     '-N'
+          Brings the Nth directory (counting from the right of the list
+          printed by 'dirs', starting with zero) to the top of the list
+          by rotating the stack.
+     'DIR'
+          Makes DIR be the top of the stack.
+
+     After the stack has been modified, if the '-n' option was not
+     supplied, 'pushd' uses the 'cd' builtin to change to the directory
+     at the top of the stack.  If the 'cd' fails, 'pushd' returns a
+     non-zero value.
+
+     Otherwise, if no arguments are supplied, 'pushd' returns 0 unless
+     the directory stack is empty.  When rotating the directory stack,
+     'pushd' returns 0 unless the directory stack is empty or a
+     non-existent directory stack element is specified.
+
+     If the 'pushd' command is successful, Bash runs 'dirs' to show the
+     final contents of the directory stack.

+
+6.9 Controlling the Prompt
+==========================
+
+Bash examines the value of the array variable 'PROMPT_COMMAND' just
+before printing each primary prompt.  If any elements in
+'PROMPT_COMMAND' are set and non-null, Bash executes each value, in
+numeric order, just as if it had been typed on the command line.
+
+   In addition, the following table describes the special characters
+which can appear in the prompt variables 'PS0', 'PS1', 'PS2', and 'PS4':
+
+'\a'
+     A bell character.
+'\d'
+     The date, in "Weekday Month Date" format (e.g., "Tue May 26").
+'\D{FORMAT}'
+     The FORMAT is passed to 'strftime'(3) and the result is inserted
+     into the prompt string; an empty FORMAT results in a
+     locale-specific time representation.  The braces are required.
+'\e'
+     An escape character.
+'\h'
+     The hostname, up to the first '.'.
+'\H'
+     The hostname.
+'\j'
+     The number of jobs currently managed by the shell.
+'\l'
+     The basename of the shell's terminal device name.
+'\n'
+     A newline.
+'\r'
+     A carriage return.
+'\s'
+     The name of the shell, the basename of '$0' (the portion following
+     the final slash).
+'\t'
+     The time, in 24-hour HH:MM:SS format.
+'\T'
+     The time, in 12-hour HH:MM:SS format.
+'\@'
+     The time, in 12-hour am/pm format.
+'\A'
+     The time, in 24-hour HH:MM format.
+'\u'
+     The username of the current user.
+'\v'
+     The version of Bash (e.g., 2.00)
+'\V'
+     The release of Bash, version + patchlevel (e.g., 2.00.0)
+'\w'
+     The value of the 'PWD' shell variable ('$PWD'), with '$HOME'
+     abbreviated with a tilde (uses the '$PROMPT_DIRTRIM' variable).
+'\W'
+     The basename of '$PWD', with '$HOME' abbreviated with a tilde.
+'\!'
+     The history number of this command.
+'\#'
+     The command number of this command.
+'\$'
+     If the effective uid is 0, '#', otherwise '$'.
+'\NNN'
+     The character whose ASCII code is the octal value NNN.
+'\\'
+     A backslash.
+'\['
+     Begin a sequence of non-printing characters.  This could be used to
+     embed a terminal control sequence into the prompt.
+'\]'
+     End a sequence of non-printing characters.
+
+   The command number and the history number are usually different: the
+history number of a command is its position in the history list, which
+may include commands restored from the history file (*note Bash History
+Facilities::), while the command number is the position in the sequence
+of commands executed during the current shell session.
+
+   After the string is decoded, it is expanded via parameter expansion,
+command substitution, arithmetic expansion, and quote removal, subject
+to the value of the 'promptvars' shell option (*note The Shopt
+Builtin::).  This can have unwanted side effects if escaped portions of
+the string appear within command substitution or contain characters
+special to word expansion.

+
+6.10 The Restricted Shell
+=========================
+
+If Bash is started with the name 'rbash', or the '--restricted' or '-r'
+option is supplied at invocation, the shell becomes restricted.  A
+restricted shell is used to set up an environment more controlled than
+the standard shell.  A restricted shell behaves identically to 'bash'
+with the exception that the following are disallowed or not performed:
+
+   * Changing directories with the 'cd' builtin.
+   * Setting or unsetting the values of the 'SHELL', 'PATH', 'HISTFILE',
+     'ENV', or 'BASH_ENV' variables.
+   * Specifying command names containing slashes.
+   * Specifying a filename containing a slash as an argument to the '.'
+     builtin command.
+   * Specifying a filename containing a slash as an argument to the
+     'history' builtin command.
+   * Specifying a filename containing a slash as an argument to the '-p'
+     option to the 'hash' builtin command.
+   * Importing function definitions from the shell environment at
+     startup.
+   * Parsing the value of 'SHELLOPTS' from the shell environment at
+     startup.
+   * Redirecting output using the '>', '>|', '<>', '>&', '&>', and '>>'
+     redirection operators.
+   * Using the 'exec' builtin to replace the shell with another command.
+   * Adding or deleting builtin commands with the '-f' and '-d' options
+     to the 'enable' builtin.
+   * Using the 'enable' builtin command to enable disabled shell
+     builtins.
+   * Specifying the '-p' option to the 'command' builtin.
+   * Turning off restricted mode with 'set +r' or 'shopt -u
+     restricted_shell'.
+
+   These restrictions are enforced after any startup files are read.
+
+   When a command that is found to be a shell script is executed (*note
+Shell Scripts::), 'rbash' turns off any restrictions in the shell
+spawned to execute the script.
+
+   The restricted shell mode is only one component of a useful
+restricted environment.  It should be accompanied by setting 'PATH' to a
+value that allows execution of only a few verified commands (commands
+that allow shell escapes are particularly vulnerable), changing the
+current directory to a non-writable directory other than '$HOME' after
+login, not allowing the restricted shell to execute shell scripts, and
+cleaning the environment of variables that cause some commands to modify
+their behavior (e.g., 'VISUAL' or 'PAGER').
+
+   Modern systems provide more secure ways to implement a restricted
+environment, such as 'jails', 'zones', or 'containers'.
+
+
+File: bash.info,  Node: Bash POSIX Mode,  Next: Shell Compatibility Mode,  Prev: The Restricted Shell,  Up: Bash Features
+
+6.11 Bash POSIX Mode
+====================
+
+Starting Bash with the '--posix' command-line option or executing 'set
+-o posix' while Bash is running will cause Bash to conform more closely
+to the POSIX standard by changing the behavior to match that specified
+by POSIX in areas where the Bash default differs.
+
+   When invoked as 'sh', Bash enters POSIX mode after reading the
+startup files.
+
+   The following list is what's changed when 'POSIX mode' is in effect:
+
+  1. Bash ensures that the 'POSIXLY_CORRECT' variable is set.
+
+  2. When a command in the hash table no longer exists, Bash will
+     re-search '$PATH' to find the new location.  This is also available
+     with 'shopt -s checkhash'.
+
+  3. Bash will not insert a command without the execute bit set into the
+     command hash table, even if it returns it as a (last-ditch) result
+     from a '$PATH' search.
+
+  4. The message printed by the job control code and builtins when a job
+     exits with a non-zero status is 'Done(status)'.
+
+  5. The message printed by the job control code and builtins when a job
+     is stopped is 'Stopped(SIGNAME)', where SIGNAME is, for example,
+     'SIGTSTP'.
+
+  6. Alias expansion is always enabled, even in non-interactive shells.
+
+  7. Reserved words appearing in a context where reserved words are
+     recognized do not undergo alias expansion.
+
+  8. Alias expansion is performed when initially parsing a command
+     substitution.  The default mode generally defers it, when enabled,
+     until the command substitution is executed.  This means that
+     command substitution will not expand aliases that are defined after
+     the command substitution is initially parsed (e.g., as part of a
+     function definition).
+
+  9. The POSIX 'PS1' and 'PS2' expansions of '!' to the history number
+     and '!!' to '!' are enabled, and parameter expansion is performed
+     on the values of 'PS1' and 'PS2' regardless of the setting of the
+     'promptvars' option.
+
+  10. The POSIX startup files are executed ('$ENV') rather than the
+     normal Bash files.
+
+  11. Tilde expansion is only performed on assignments preceding a
+     command name, rather than on all assignment statements on the line.
+
+  12. The default history file is '~/.sh_history' (this is the default
+     value of '$HISTFILE').
+
+  13. Redirection operators do not perform filename expansion on the
+     word in the redirection unless the shell is interactive.
+
+  14. Redirection operators do not perform word splitting on the word in
+     the redirection.
+
+  15. Function names must be valid shell 'name's.  That is, they may not
+     contain characters other than letters, digits, and underscores, and
+     may not start with a digit.  Declaring a function with an invalid
+     name causes a fatal syntax error in non-interactive shells.
+
+  16. Function names may not be the same as one of the POSIX special
+     builtins.
+
+  17. POSIX special builtins are found before shell functions during
+     command lookup.
+
+  18. When printing shell function definitions (e.g., by 'type'), Bash
+     does not print the 'function' keyword.
+
+  19. Literal tildes that appear as the first character in elements of
+     the 'PATH' variable are not expanded as described above under *note
+     Tilde Expansion::.
+
+  20. The 'time' reserved word may be used by itself as a command.  When
+     used in this way, it displays timing statistics for the shell and
+     its completed children.  The 'TIMEFORMAT' variable controls the
+     format of the timing information.
+
+  21. When parsing and expanding a ${...} expansion that appears within
+     double quotes, single quotes are no longer special and cannot be
+     used to quote a closing brace or other special character, unless
+     the operator is one of those defined to perform pattern removal.
+     In this case, they do not have to appear as matched pairs.
+
+  22. The parser does not recognize 'time' as a reserved word if the
+     next token begins with a '-'.
+
+  23. The '!' character does not introduce history expansion within a
+     double-quoted string, even if the 'histexpand' option is enabled.
+
+  24. If a POSIX special builtin returns an error status, a
+     non-interactive shell exits.  The fatal errors are those listed in
+     the POSIX standard, and include things like passing incorrect
+     options, redirection errors, variable assignment errors for
+     assignments preceding the command name, and so on.
+
+  25. A non-interactive shell exits with an error status if a variable
+     assignment error occurs when no command name follows the assignment
+     statements.  A variable assignment error occurs, for example, when
+     trying to assign a value to a readonly variable.
+
+  26. A non-interactive shell exits with an error status if a variable
+     assignment error occurs in an assignment statement preceding a
+     special builtin, but not with any other simple command.  For any
+     other simple command, the shell aborts execution of that command,
+     and execution continues at the top level ("the shell shall not
+     perform any further processing of the command in which the error
+     occurred").
+
+  27. A non-interactive shell exits with an error status if the
+     iteration variable in a 'for' statement or the selection variable
+     in a 'select' statement is a readonly variable.
+
+  28. Non-interactive shells exit if FILENAME in '.'  FILENAME is not
+     found.
+
+  29. Non-interactive shells exit if a syntax error in an arithmetic
+     expansion results in an invalid expression.
+
+  30. Non-interactive shells exit if a parameter expansion error occurs.
+
+  31. Non-interactive shells exit if there is a syntax error in a script
+     read with the '.' or 'source' builtins, or in a string processed by
+     the 'eval' builtin.
+
+  32. While variable indirection is available, it may not be applied to
+     the '#' and '?' special parameters.
+
+  33. Expanding the '*' special parameter in a pattern context where the
+     expansion is double-quoted does not treat the '$*' as if it were
+     double-quoted.
+
+  34. Assignment statements preceding POSIX special builtins persist in
+     the shell environment after the builtin completes.
+
+  35. The 'command' builtin does not prevent builtins that take
+     assignment statements as arguments from expanding them as
+     assignment statements; when not in POSIX mode, assignment builtins
+     lose their assignment statement expansion properties when preceded
+     by 'command'.
+
+  36. The 'bg' builtin uses the required format to describe each job
+     placed in the background, which does not include an indication of
+     whether the job is the current or previous job.
+
+  37. The output of 'kill -l' prints all the signal names on a single
+     line, separated by spaces, without the 'SIG' prefix.
+
+  38. The 'kill' builtin does not accept signal names with a 'SIG'
+     prefix.
+
+  39. The 'export' and 'readonly' builtin commands display their output
+     in the format required by POSIX.
+
+  40. The 'trap' builtin displays signal names without the leading
+     'SIG'.
+
+  41. The 'trap' builtin doesn't check the first argument for a possible
+     signal specification and revert the signal handling to the original
+     disposition if it is, unless that argument consists solely of
+     digits and is a valid signal number.  If users want to reset the
+     handler for a given signal to the original disposition, they should
+     use '-' as the first argument.
+
+  42. 'trap -p' displays signals whose dispositions are set to SIG_DFL
+     and those that were ignored when the shell started.
+
+  43. The '.' and 'source' builtins do not search the current directory
+     for the filename argument if it is not found by searching 'PATH'.
+
+  44. Enabling POSIX mode has the effect of setting the
+     'inherit_errexit' option, so subshells spawned to execute command
+     substitutions inherit the value of the '-e' option from the parent
+     shell.  When the 'inherit_errexit' option is not enabled, Bash
+     clears the '-e' option in such subshells.
+
+  45. Enabling POSIX mode has the effect of setting the 'shift_verbose'
+     option, so numeric arguments to 'shift' that exceed the number of
+     positional parameters will result in an error message.
+
+  46. When the 'alias' builtin displays alias definitions, it does not
+     display them with a leading 'alias ' unless the '-p' option is
+     supplied.
+
+  47. When the 'set' builtin is invoked without options, it does not
+     display shell function names and definitions.
+
+  48. When the 'set' builtin is invoked without options, it displays
+     variable values without quotes, unless they contain shell
+     metacharacters, even if the result contains nonprinting characters.
+
+  49. When the 'cd' builtin is invoked in logical mode, and the pathname
+     constructed from '$PWD' and the directory name supplied as an
+     argument does not refer to an existing directory, 'cd' will fail
+     instead of falling back to physical mode.
+
+  50. When the 'cd' builtin cannot change a directory because the length
+     of the pathname constructed from '$PWD' and the directory name
+     supplied as an argument exceeds 'PATH_MAX' when all symbolic links
+     are expanded, 'cd' will fail instead of attempting to use only the
+     supplied directory name.
+
+  51. The 'pwd' builtin verifies that the value it prints is the same as
+     the current directory, even if it is not asked to check the file
+     system with the '-P' option.
+
+  52. When listing the history, the 'fc' builtin does not include an
+     indication of whether or not a history entry has been modified.
+
+  53. The default editor used by 'fc' is 'ed'.
+
+  54. The 'type' and 'command' builtins will not report a non-executable
+     file as having been found, though the shell will attempt to execute
+     such a file if it is the only so-named file found in '$PATH'.
+
+  55. The 'vi' editing mode will invoke the 'vi' editor directly when
+     the 'v' command is run, instead of checking '$VISUAL' and
+     '$EDITOR'.
+
+  56. When the 'xpg_echo' option is enabled, Bash does not attempt to
+     interpret any arguments to 'echo' as options.  Each argument is
+     displayed, after escape characters are converted.
+
+  57. The 'ulimit' builtin uses a block size of 512 bytes for the '-c'
+     and '-f' options.
+
+  58. The arrival of 'SIGCHLD' when a trap is set on 'SIGCHLD' does not
+     interrupt the 'wait' builtin and cause it to return immediately.
+     The trap command is run once for each child that exits.
+
+  59. The 'read' builtin may be interrupted by a signal for which a trap
+     has been set.  If Bash receives a trapped signal while executing
+     'read', the trap handler executes and 'read' returns an exit status
+     greater than 128.
+
+  60. The 'printf' builtin uses 'double' (via 'strtod') to convert
+     arguments corresponding to floating point conversion specifiers,
+     instead of 'long double' if it's available.  The 'L' length
+     modifier forces 'printf' to use 'long double' if it's available.
+
+  61. Bash removes an exited background process's status from the list
+     of such statuses after the 'wait' builtin is used to obtain it.
+
+   There is other POSIX behavior that Bash does not implement by default
+even when in POSIX mode.  Specifically:
+
+  1. The 'fc' builtin checks '$EDITOR' as a program to edit history
+     entries if 'FCEDIT' is unset, rather than defaulting directly to
+     'ed'.  'fc' uses 'ed' if 'EDITOR' is unset.
+
+  2. As noted above, Bash requires the 'xpg_echo' option to be enabled
+     for the 'echo' builtin to be fully conformant.
+
+   Bash can be configured to be POSIX-conformant by default, by
+specifying the '--enable-strict-posix-default' to 'configure' when
+building (*note Optional Features::).

+
+6.12 Shell Compatibility Mode
+=============================
+
+Bash-4.0 introduced the concept of a "shell compatibility level",
+specified as a set of options to the shopt builtin ('compat31',
+'compat32', 'compat40', 'compat41', and so on).  There is only one
+current compatibility level - each option is mutually exclusive.  The
+compatibility level is intended to allow users to select behavior from
+previous versions that is incompatible with newer versions while they
+migrate scripts to use current features and behavior.  It's intended to
+be a temporary solution.
+
+   This section does not mention behavior that is standard for a
+particular version (e.g., setting 'compat32' means that quoting the rhs
+of the regexp matching operator quotes special regexp characters in the
+word, which is default behavior in bash-3.2 and subsequent versions).
+
+   If a user enables, say, 'compat32', it may affect the behavior of
+other compatibility levels up to and including the current compatibility
+level.  The idea is that each compatibility level controls behavior that
+changed in that version of Bash, but that behavior may have been present
+in earlier versions.  For instance, the change to use locale-based
+comparisons with the '[[' command came in bash-4.1, and earlier versions
+used ASCII-based comparisons, so enabling 'compat32' will enable
+ASCII-based comparisons as well.  That granularity may not be sufficient
+for all uses, and as a result users should employ compatibility levels
+carefully.  Read the documentation for a particular feature to find out
+the current behavior.
+
+   Bash-4.3 introduced a new shell variable: 'BASH_COMPAT'.  The value
+assigned to this variable (a decimal version number like 4.2, or an
+integer corresponding to the 'compat'NN option, like 42) determines the
+compatibility level.
+
+   Starting with bash-4.4, Bash has begun deprecating older
+compatibility levels.  Eventually, the options will be removed in favor
+of 'BASH_COMPAT'.
+
+   Bash-5.0 is the final version for which there will be an individual
+shopt option for the previous version.  Users should use 'BASH_COMPAT'
+on bash-5.0 and later versions.
+
+   The following table describes the behavior changes controlled by each
+compatibility level setting.  The 'compat'NN tag is used as shorthand
+for setting the compatibility level to NN using one of the following
+mechanisms.  For versions prior to bash-5.0, the compatibility level may
+be set using the corresponding 'compat'NN shopt option.  For bash-4.3
+and later versions, the 'BASH_COMPAT' variable is preferred, and it is
+required for bash-5.1 and later versions.
+
+'compat31'
+        * quoting the rhs of the '[[' command's regexp matching operator
+          (=~) has no special effect
+
+'compat32'
+        * interrupting a command list such as "a ; b ; c" causes the
+          execution of the next command in the list (in bash-4.0 and
+          later versions, the shell acts as if it received the
+          interrupt, so interrupting one command in a list aborts the
+          execution of the entire list)
+
+'compat40'
+        * the '<' and '>' operators to the '[[' command do not consider
+          the current locale when comparing strings; they use ASCII
+          ordering.  Bash versions prior to bash-4.1 use ASCII collation
+          and strcmp(3); bash-4.1 and later use the current locale's
+          collation sequence and strcoll(3).
+
+'compat41'
+        * in posix mode, 'time' may be followed by options and still be
+          recognized as a reserved word (this is POSIX interpretation
+          267)
+        * in posix mode, the parser requires that an even number of
+          single quotes occur in the WORD portion of a double-quoted
+          ${...} parameter expansion and treats them specially, so that
+          characters within the single quotes are considered quoted
+          (this is POSIX interpretation 221)
+
+'compat42'
+        * the replacement string in double-quoted pattern substitution
+          does not undergo quote removal, as it does in versions after
+          bash-4.2
+        * in posix mode, single quotes are considered special when
+          expanding the WORD portion of a double-quoted ${...} parameter
+          expansion and can be used to quote a closing brace or other
+          special character (this is part of POSIX interpretation 221);
+          in later versions, single quotes are not special within
+          double-quoted word expansions
+
+'compat43'
+        * the shell does not print a warning message if an attempt is
+          made to use a quoted compound assignment as an argument to
+          declare (e.g., declare -a foo='(1 2)').  Later versions warn
+          that this usage is deprecated
+        * word expansion errors are considered non-fatal errors that
+          cause the current command to fail, even in posix mode (the
+          default behavior is to make them fatal errors that cause the
+          shell to exit)
+        * when executing a shell function, the loop state
+          (while/until/etc.)  is not reset, so 'break' or 'continue' in
+          that function will break or continue loops in the calling
+          context.  Bash-4.4 and later reset the loop state to prevent
+          this
+
+'compat44'
+        * the shell sets up the values used by 'BASH_ARGV' and
+          'BASH_ARGC' so they can expand to the shell's positional
+          parameters even if extended debugging mode is not enabled
+        * a subshell inherits loops from its parent context, so 'break'
+          or 'continue' will cause the subshell to exit.  Bash-5.0 and
+          later reset the loop state to prevent the exit
+        * variable assignments preceding builtins like 'export' and
+          'readonly' that set attributes continue to affect variables
+          with the same name in the calling environment even if the
+          shell is not in posix mode
+
+'compat50 (set using BASH_COMPAT)'
+        * Bash-5.1 changed the way '$RANDOM' is generated to introduce
+          slightly more randomness.  If the shell compatibility level is
+          set to 50 or lower, it reverts to the method from bash-5.0 and
+          previous versions, so seeding the random number generator by
+          assigning a value to 'RANDOM' will produce the same sequence
+          as in bash-5.0
+        * If the command hash table is empty, Bash versions prior to
+          bash-5.1 printed an informational message to that effect, even
+          when producing output that can be reused as input.  Bash-5.1
+          suppresses that message when the '-l' option is supplied.
+
+'compat51 (set using BASH_COMPAT)'
+        * The 'unset' builtin will unset the array 'a' given an argument
+          like 'a[@]'.  Bash-5.2 will unset an element with key '@'
+          (associative arrays) or remove all the elements without
+          unsetting the array (indexed arrays)
+        * arithmetic commands ( ((...))  )  and the expressions in an
+          arithmetic for statement can be expanded more than once
+        * expressions used as arguments to arithmetic operators in the
+          '[[' conditional command can be expanded more than once
+        * the expressions in substring parameter brace expansion can be
+          expanded more than once
+        * the expressions in the $(( ...  ))  word expansion can be
+          expanded more than once
+        * arithmetic expressions used as indexed array subscripts can be
+          expanded more than once
+        * 'test -v', when given an argument of 'A[@]', where A is an
+          existing associative array, will return true if the array has
+          any set elements.  Bash-5.2 will look for and report on a key
+          named '@'
+        * the ${PARAMETER[:]=VALUE} word expansion will return VALUE,
+          before any variable-specific transformations have been
+          performed (e.g., converting to lowercase).  Bash-5.2 will
+          return the final value assigned to the variable.
+        * Parsing command substitutions will behave as if extended glob
+          (*note The Shopt Builtin::) is enabled, so that parsing a
+          command substitution containing an extglob pattern (say, as
+          part of a shell function) will not fail.  This assumes the
+          intent is to enable extglob before the command is executed and
+          word expansions are performed.  It will fail at word expansion
+          time if extglob hasn't been enabled by the time the command is
+          executed.

+7 Job Control
+*************
+
+This chapter discusses what job control is, how it works, and how Bash
+allows you to access its facilities.

+
+
+File: bash.info,  Node: Job Control Basics,  Next: Job Control Builtins,  Up: Job Control
+
+7.1 Job Control Basics
+======================
+
+Job control refers to the ability to selectively stop (suspend) the
+execution of processes and continue (resume) their execution at a later
+point.  A user typically employs this facility via an interactive
+interface supplied jointly by the operating system kernel's terminal
+driver and Bash.
+
+   The shell associates a JOB with each pipeline.  It keeps a table of
+currently executing jobs, which may be listed with the 'jobs' command.
+When Bash starts a job asynchronously, it prints a line that looks like:
+     [1] 25647
+indicating that this job is job number 1 and that the process ID of the
+last process in the pipeline associated with this job is 25647.  All of
+the processes in a single pipeline are members of the same job.  Bash
+uses the JOB abstraction as the basis for job control.
+
+   To facilitate the implementation of the user interface to job
+control, the operating system maintains the notion of a current terminal
+process group ID.  Members of this process group (processes whose
+process group ID is equal to the current terminal process group ID)
+receive keyboard-generated signals such as 'SIGINT'.  These processes
+are said to be in the foreground.  Background processes are those whose
+process group ID differs from the terminal's; such processes are immune
+to keyboard-generated signals.  Only foreground processes are allowed to
+read from or, if the user so specifies with 'stty tostop', write to the
+terminal.  Background processes which attempt to read from (write to
+when 'stty tostop' is in effect) the terminal are sent a 'SIGTTIN'
+('SIGTTOU') signal by the kernel's terminal driver, which, unless
+caught, suspends the process.
+
+   If the operating system on which Bash is running supports job
+control, Bash contains facilities to use it.  Typing the "suspend"
+character (typically '^Z', Control-Z) while a process is running causes
+that process to be stopped and returns control to Bash.  Typing the
+"delayed suspend" character (typically '^Y', Control-Y) causes the
+process to be stopped when it attempts to read input from the terminal,
+and control to be returned to Bash.  The user then manipulates the state
+of this job, using the 'bg' command to continue it in the background,
+the 'fg' command to continue it in the foreground, or the 'kill' command
+to kill it.  A '^Z' takes effect immediately, and has the additional
+side effect of causing pending output and typeahead to be discarded.
+
+   There are a number of ways to refer to a job in the shell.  The
+character '%' introduces a job specification ("jobspec").
+
+   Job number 'n' may be referred to as '%n'.  The symbols '%%' and '%+'
+refer to the shell's notion of the current job, which is the last job
+stopped while it was in the foreground or started in the background.  A
+single '%' (with no accompanying job specification) also refers to the
+current job.  The previous job may be referenced using '%-'.  If there
+is only a single job, '%+' and '%-' can both be used to refer to that
+job.  In output pertaining to jobs (e.g., the output of the 'jobs'
+command), the current job is always flagged with a '+', and the previous
+job with a '-'.
+
+   A job may also be referred to using a prefix of the name used to
+start it, or using a substring that appears in its command line.  For
+example, '%ce' refers to a stopped job whose command name begins with
+'ce'.  Using '%?ce', on the other hand, refers to any job containing the
+string 'ce' in its command line.  If the prefix or substring matches
+more than one job, Bash reports an error.
+
+   Simply naming a job can be used to bring it into the foreground: '%1'
+is a synonym for 'fg %1', bringing job 1 from the background into the
+foreground.  Similarly, '%1 &' resumes job 1 in the background,
+equivalent to 'bg %1'
+
+   The shell learns immediately whenever a job changes state.  Normally,
+Bash waits until it is about to print a prompt before reporting changes
+in a job's status so as to not interrupt any other output.  If the '-b'
+option to the 'set' builtin is enabled, Bash reports such changes
+immediately (*note The Set Builtin::).  Any trap on 'SIGCHLD' is
+executed for each child process that exits.
+
+   If an attempt to exit Bash is made while jobs are stopped, (or
+running, if the 'checkjobs' option is enabled - see *note The Shopt
+Builtin::), the shell prints a warning message, and if the 'checkjobs'
+option is enabled, lists the jobs and their statuses.  The 'jobs'
+command may then be used to inspect their status.  If a second attempt
+to exit is made without an intervening command, Bash does not print
+another warning, and any stopped jobs are terminated.
+
+   When the shell is waiting for a job or process using the 'wait'
+builtin, and job control is enabled, 'wait' will return when the job
+changes state.  The '-f' option causes 'wait' to wait until the job or
+process terminates before returning.

+
+7.2 Job Control Builtins
+========================
+
+'bg'
+          bg [JOBSPEC ...]
+
+     Resume each suspended job JOBSPEC in the background, as if it had
+     been started with '&'.  If JOBSPEC is not supplied, the current job
+     is used.  The return status is zero unless it is run when job
+     control is not enabled, or, when run with job control enabled, any
+     JOBSPEC was not found or specifies a job that was started without
+     job control.
+
+'fg'
+          fg [JOBSPEC]
+
+     Resume the job JOBSPEC in the foreground and make it the current
+     job.  If JOBSPEC is not supplied, the current job is used.  The
+     return status is that of the command placed into the foreground, or
+     non-zero if run when job control is disabled or, when run with job
+     control enabled, JOBSPEC does not specify a valid job or JOBSPEC
+     specifies a job that was started without job control.
+
+'jobs'
+          jobs [-lnprs] [JOBSPEC]
+          jobs -x COMMAND [ARGUMENTS]
+
+     The first form lists the active jobs.  The options have the
+     following meanings:
+
+     '-l'
+          List process IDs in addition to the normal information.
+
+     '-n'
+          Display information only about jobs that have changed status
+          since the user was last notified of their status.
+
+     '-p'
+          List only the process ID of the job's process group leader.
+
+     '-r'
+          Display only running jobs.
+
+     '-s'
+          Display only stopped jobs.
+
+     If JOBSPEC is given, output is restricted to information about that
+     job.  If JOBSPEC is not supplied, the status of all jobs is listed.
+
+     If the '-x' option is supplied, 'jobs' replaces any JOBSPEC found
+     in COMMAND or ARGUMENTS with the corresponding process group ID,
+     and executes COMMAND, passing it ARGUMENTs, returning its exit
+     status.
+
+'kill'
+          kill [-s SIGSPEC] [-n SIGNUM] [-SIGSPEC] JOBSPEC or PID
+          kill -l|-L [EXIT_STATUS]
+
+     Send a signal specified by SIGSPEC or SIGNUM to the process named
+     by job specification JOBSPEC or process ID PID.  SIGSPEC is either
+     a case-insensitive signal name such as 'SIGINT' (with or without
+     the 'SIG' prefix) or a signal number; SIGNUM is a signal number.
+     If SIGSPEC and SIGNUM are not present, 'SIGTERM' is used.  The '-l'
+     option lists the signal names.  If any arguments are supplied when
+     '-l' is given, the names of the signals corresponding to the
+     arguments are listed, and the return status is zero.  EXIT_STATUS
+     is a number specifying a signal number or the exit status of a
+     process terminated by a signal.  The '-L' option is equivalent to
+     '-l'.  The return status is zero if at least one signal was
+     successfully sent, or non-zero if an error occurs or an invalid
+     option is encountered.
+
+'wait'
+          wait [-fn] [-p VARNAME] [JOBSPEC or PID ...]
+
+     Wait until the child process specified by each process ID PID or
+     job specification JOBSPEC exits and return the exit status of the
+     last command waited for.  If a job spec is given, all processes in
+     the job are waited for.  If no arguments are given, 'wait' waits
+     for all running background jobs and the last-executed process
+     substitution, if its process id is the same as $!, and the return
+     status is zero.  If the '-n' option is supplied, 'wait' waits for a
+     single job from the list of PIDs or JOBSPECs or, if no arguments
+     are supplied, any job, to complete and returns its exit status.  If
+     none of the supplied arguments is a child of the shell, or if no
+     arguments are supplied and the shell has no unwaited-for children,
+     the exit status is 127.  If the '-p' option is supplied, the
+     process or job identifier of the job for which the exit status is
+     returned is assigned to the variable VARNAME named by the option
+     argument.  The variable will be unset initially, before any
+     assignment.  This is useful only when the '-n' option is supplied.
+     Supplying the '-f' option, when job control is enabled, forces
+     'wait' to wait for each PID or JOBSPEC to terminate before
+     returning its status, instead of returning when it changes status.
+     If neither JOBSPEC nor PID specifies an active child process of the
+     shell, the return status is 127.  If 'wait' is interrupted by a
+     signal, the return status will be greater than 128, as described
+     above (*note Signals::).  Otherwise, the return status is the exit
+     status of the last process or job waited for.
+
+'disown'
+          disown [-ar] [-h] [JOBSPEC ... | PID ... ]
+
+     Without options, remove each JOBSPEC from the table of active jobs.
+     If the '-h' option is given, the job is not removed from the table,
+     but is marked so that 'SIGHUP' is not sent to the job if the shell
+     receives a 'SIGHUP'.  If JOBSPEC is not present, and neither the
+     '-a' nor the '-r' option is supplied, the current job is used.  If
+     no JOBSPEC is supplied, the '-a' option means to remove or mark all
+     jobs; the '-r' option without a JOBSPEC argument restricts
+     operation to running jobs.
+
+'suspend'
+          suspend [-f]
+
+     Suspend the execution of this shell until it receives a 'SIGCONT'
+     signal.  A login shell, or a shell without job control enabled,
+     cannot be suspended; the '-f' option can be used to override this
+     and force the suspension.  The return status is 0 unless the shell
+     is a login shell or job control is not enabled and '-f' is not
+     supplied.
+
+   When job control is not active, the 'kill' and 'wait' builtins do not
+accept JOBSPEC arguments.  They must be supplied process IDs.

+
+7.3 Job Control Variables
+=========================
+
+'auto_resume'
+     This variable controls how the shell interacts with the user and
+     job control.  If this variable exists then single word simple
+     commands without redirections are treated as candidates for
+     resumption of an existing job.  There is no ambiguity allowed; if
+     there is more than one job beginning with the string typed, then
+     the most recently accessed job will be selected.  The name of a
+     stopped job, in this context, is the command line used to start it.
+     If this variable is set to the value 'exact', the string supplied
+     must match the name of a stopped job exactly; if set to
+     'substring', the string supplied needs to match a substring of the
+     name of a stopped job.  The 'substring' value provides
+     functionality analogous to the '%?' job ID (*note Job Control
+     Basics::).  If set to any other value, the supplied string must be
+     a prefix of a stopped job's name; this provides functionality
+     analogous to the '%' job ID.

+8 Command Line Editing
+**********************
+
+This chapter describes the basic features of the GNU command line
+editing interface.  Command line editing is provided by the Readline
+library, which is used by several different programs, including Bash.
+Command line editing is enabled by default when using an interactive
+shell, unless the '--noediting' option is supplied at shell invocation.
+Line editing is also used when using the '-e' option to the 'read'
+builtin command (*note Bash Builtins::).  By default, the line editing
+commands are similar to those of Emacs.  A vi-style line editing
+interface is also available.  Line editing can be enabled at any time
+using the '-o emacs' or '-o vi' options to the 'set' builtin command
+(*note The Set Builtin::), or disabled using the '+o emacs' or '+o vi'

+8.1 Introduction to Line Editing
+================================
+
+The following paragraphs describe the notation used to represent
+keystrokes.
+
+   The text 'C-k' is read as 'Control-K' and describes the character
+produced when the <k> key is pressed while the Control key is depressed.
+
+   The text 'M-k' is read as 'Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the <k>
+key is pressed.  The Meta key is labeled <ALT> on many keyboards.  On
+keyboards with two keys labeled <ALT> (usually to either side of the
+space bar), the <ALT> on the left side is generally set to work as a
+Meta key.  The <ALT> key on the right may also be configured to work as
+a Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+
+   If you do not have a Meta or <ALT> key, or another key working as a
+Meta key, the identical keystroke can be generated by typing <ESC>
+_first_, and then typing <k>.  Either process is known as "metafying"
+the <k> key.
+
+   The text 'M-C-k' is read as 'Meta-Control-k' and describes the
+character produced by "metafying" 'C-k'.
+
+   In addition, several keys have their own names.  Specifically, <DEL>,
+<ESC>, <LFD>, <SPC>, <RET>, and <TAB> all stand for themselves when seen
+in this text, or in an init file (*note Readline Init File::).  If your
+keyboard lacks a <LFD> key, typing <C-j> will produce the desired
+character.  The <RET> key may be labeled <Return> or <Enter> on some
+keyboards.

+8.2 Readline Interaction
+========================
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled.  The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line.  Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections.  Then, when you are satisfied with
+the line, you simply press <RET>.  You do not have to be at the end of
+the line to press <RET>; the entire line is accepted regardless of the
+location of the cursor within the line.

+
+8.2.1 Readline Bare Essentials
+------------------------------
+
+In order to enter characters into the line, simply type them.  The typed
+character appears where the cursor was, and then the cursor moves one
+space to the right.  If you mistype a character, you can use your erase
+character to back up and delete the mistyped character.
+
+   Sometimes you may mistype a character, and not notice the error until
+you have typed several other characters.  In that case, you can type
+'C-b' to move the cursor to the left, and then correct your mistake.
+Afterwards, you can move the cursor to the right with 'C-f'.
+
+   When you add text in the middle of a line, you will notice that
+characters to the right of the cursor are 'pushed over' to make room for
+the text that you have inserted.  Likewise, when you delete text behind
+the cursor, characters to the right of the cursor are 'pulled back' to
+fill in the blank space created by the removal of the text.  A list of
+the bare essentials for editing the text of an input line follows.
+
+'C-b'
+     Move back one character.
+'C-f'
+     Move forward one character.
+<DEL> or <Backspace>
+     Delete the character to the left of the cursor.
+'C-d'
+     Delete the character underneath the cursor.
+Printing characters
+     Insert the character into the line at the cursor.
+'C-_' or 'C-x C-u'
+     Undo the last editing command.  You can undo all the way back to an
+     empty line.
+
+(Depending on your configuration, the <Backspace> key might be set to
+delete the character to the left of the cursor and the <DEL> key set to
+delete the character underneath the cursor, like 'C-d', rather than the
+character to the left of the cursor.)

+
+8.2.2 Readline Movement Commands
+--------------------------------
+
+The above table describes the most basic keystrokes that you need in
+order to do editing of the input line.  For your convenience, many other
+commands have been added in addition to 'C-b', 'C-f', 'C-d', and <DEL>.
+Here are some commands for moving more rapidly about the line.
+
+'C-a'
+     Move to the start of the line.
+'C-e'
+     Move to the end of the line.
+'M-f'
+     Move forward a word, where a word is composed of letters and
+     digits.
+'M-b'
+     Move backward a word.
+'C-l'
+     Clear the screen, reprinting the current line at the top.
+
+   Notice how 'C-f' moves forward a character, while 'M-f' moves forward
+a word.  It is a loose convention that control keystrokes operate on
+characters while meta keystrokes operate on words.

+
+8.2.3 Readline Killing Commands
+-------------------------------
+
+"Killing" text means to delete the text from the line, but to save it
+away for later use, usually by "yanking" (re-inserting) it back into the
+line.  ('Cut' and 'paste' are more recent jargon for 'kill' and 'yank'.)
+
+   If the description for a command says that it 'kills' text, then you
+can be sure that you can get the text back in a different (or the same)
+place later.
+
+   When you use a kill command, the text is saved in a "kill-ring".  Any
+number of consecutive kills save all of the killed text together, so
+that when you yank it back, you get it all.  The kill ring is not line
+specific; the text that you killed on a previously typed line is
+available to be yanked back later, when you are typing another line.
+
+   Here is the list of commands for killing text.
+
+'C-k'
+     Kill the text from the current cursor position to the end of the
+     line.
+
+'M-d'
+     Kill from the cursor to the end of the current word, or, if between
+     words, to the end of the next word.  Word boundaries are the same
+     as those used by 'M-f'.
+
+'M-<DEL>'
+     Kill from the cursor to the start of the current word, or, if
+     between words, to the start of the previous word.  Word boundaries
+     are the same as those used by 'M-b'.
+
+'C-w'
+     Kill from the cursor to the previous whitespace.  This is different
+     than 'M-<DEL>' because the word boundaries differ.
+
+   Here is how to "yank" the text back into the line.  Yanking means to
+copy the most-recently-killed text from the kill buffer.
+
+'C-y'
+     Yank the most recently killed text back into the buffer at the
+     cursor.
+
+'M-y'
+     Rotate the kill-ring, and yank the new top.  You can only do this
+     if the prior command is 'C-y' or 'M-y'.
+
+
+File: bash.info,  Node: Readline Arguments,  Next: Searching,  Prev: Readline Killing Commands,  Up: Readline Interaction
+
+8.2.4 Readline Arguments
+------------------------
+
+You can pass numeric arguments to Readline commands.  Sometimes the
+argument acts as a repeat count, other times it is the sign of the
+argument that is significant.  If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction.  For example, to kill text back to the
+start of the line, you might type 'M-- C-k'.
+
+   The general way to pass numeric arguments to a command is to type
+meta digits before the command.  If the first 'digit' typed is a minus
+sign ('-'), then the sign of the argument will be negative.  Once you
+have typed one meta digit to get the argument started, you can type the
+remainder of the digits, and then the command.  For example, to give the
+'C-d' command an argument of 10, you could type 'M-1 0 C-d', which will
+delete the next ten characters on the input line.
+
+
+File: bash.info,  Node: Searching,  Prev: Readline Arguments,  Up: Readline Interaction
+
+8.2.5 Searching for Commands in the History
+-------------------------------------------
+
+Readline provides commands for searching through the command history
+(*note Bash History Facilities::) for lines containing a specified
+string.  There are two search modes: "incremental" and
+"non-incremental".
+
+   Incremental searches begin before the user has finished typing the
+search string.  As each character of the search string is typed,
+Readline displays the next entry from the history matching the string
+typed so far.  An incremental search requires only as many characters as
+needed to find the desired history entry.  To search backward in the
+history for a particular string, type 'C-r'.  Typing 'C-s' searches
+forward through the history.  The characters present in the value of the
+'isearch-terminators' variable are used to terminate an incremental
+search.  If that variable has not been assigned a value, the <ESC> and
+'C-J' characters will terminate an incremental search.  'C-g' will abort
+an incremental search and restore the original line.  When the search is
+terminated, the history entry containing the search string becomes the
+current line.
+
+   To find other matching entries in the history list, type 'C-r' or
+'C-s' as appropriate.  This will search backward or forward in the
+history for the next entry matching the search string typed so far.  Any
+other key sequence bound to a Readline command will terminate the search
+and execute that command.  For instance, a <RET> will terminate the
+search and accept the line, thereby executing the command from the
+history list.  A movement command will terminate the search, make the
+last line found the current line, and begin editing.
+
+   Readline remembers the last incremental search string.  If two 'C-r's
+are typed without any intervening characters defining a new search
+string, any remembered search string is used.
+
+   Non-incremental searches read the entire search string before
+starting to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.

+
+8.3 Readline Init File
+======================
+
+Although the Readline library comes with a set of Emacs-like keybindings
+installed by default, it is possible to use a different set of
+keybindings.  Any user can customize programs that use Readline by
+putting commands in an "inputrc" file, conventionally in their home
+directory.  The name of this file is taken from the value of the shell
+variable 'INPUTRC'.  If that variable is unset, the default is
+'~/.inputrc'.  If that file does not exist or cannot be read, the
+ultimate default is '/etc/inputrc'.  The 'bind' builtin command can also
+be used to set Readline keybindings and variables.  *Note Bash
+Builtins::.
+
+   When a program which uses the Readline library starts up, the init
+file is read, and the key bindings are set.
+
+   In addition, the 'C-x C-r' command re-reads this init file, thus
+incorporating any changes that you might have made to it.

+
+
+File: bash.info,  Node: Readline Init File Syntax,  Next: Conditional Init Constructs,  Up: Readline Init File
+
+8.3.1 Readline Init File Syntax
+-------------------------------
+
+There are only a few basic constructs allowed in the Readline init file.
+Blank lines are ignored.  Lines beginning with a '#' are comments.
+Lines beginning with a '$' indicate conditional constructs (*note
+Conditional Init Constructs::).  Other lines denote variable settings
+and key bindings.
+
+Variable Settings
+     You can modify the run-time behavior of Readline by altering the
+     values of variables in Readline using the 'set' command within the
+     init file.  The syntax is simple:
+
+          set VARIABLE VALUE
+
+     Here, for example, is how to change from the default Emacs-like key
+     binding to use 'vi' line editing commands:
+
+          set editing-mode vi
+
+     Variable names and values, where appropriate, are recognized
+     without regard to case.  Unrecognized variable names are ignored.
+
+     Boolean variables (those that can be set to on or off) are set to
+     on if the value is null or empty, ON (case-insensitive), or 1.  Any
+     other value results in the variable being set to off.
+
+     The 'bind -V' command lists the current Readline variable names and
+     values.  *Note Bash Builtins::.
+
+     A great deal of run-time behavior is changeable with the following
+     variables.
+
+     'active-region-start-color'
+          A string variable that controls the text color and background
+          when displaying the text in the active region (see the
+          description of 'enable-active-region' below).  This string
+          must not take up any physical character positions on the
+          display, so it should consist only of terminal escape
+          sequences.  It is output to the terminal before displaying the
+          text in the active region.  This variable is reset to the
+          default value whenever the terminal type changes.  The default
+          value is the string that puts the terminal in standout mode,
+          as obtained from the terminal's terminfo description.  A
+          sample value might be '\e[01;33m'.
+
+     'active-region-end-color'
+          A string variable that "undoes" the effects of
+          'active-region-start-color' and restores "normal" terminal
+          display appearance after displaying text in the active region.
+          This string must not take up any physical character positions
+          on the display, so it should consist only of terminal escape
+          sequences.  It is output to the terminal after displaying the
+          text in the active region.  This variable is reset to the
+          default value whenever the terminal type changes.  The default
+          value is the string that restores the terminal from standout
+          mode, as obtained from the terminal's terminfo description.  A
+          sample value might be '\e[0m'.
+
+     'bell-style'
+          Controls what happens when Readline wants to ring the terminal
+          bell.  If set to 'none', Readline never rings the bell.  If
+          set to 'visible', Readline uses a visible bell if one is
+          available.  If set to 'audible' (the default), Readline
+          attempts to ring the terminal's bell.
+
+     'bind-tty-special-chars'
+          If set to 'on' (the default), Readline attempts to bind the
+          control characters treated specially by the kernel's terminal
+          driver to their Readline equivalents.
+
+     'blink-matching-paren'
+          If set to 'on', Readline attempts to briefly move the cursor
+          to an opening parenthesis when a closing parenthesis is
+          inserted.  The default is 'off'.
+
+     'colored-completion-prefix'
+          If set to 'on', when listing completions, Readline displays
+          the common prefix of the set of possible completions using a
+          different color.  The color definitions are taken from the
+          value of the 'LS_COLORS' environment variable.  If there is a
+          color definition in 'LS_COLORS' for the custom suffix
+          'readline-colored-completion-prefix', Readline uses this color
+          for the common prefix instead of its default.  The default is
+          'off'.
+
+     'colored-stats'
+          If set to 'on', Readline displays possible completions using
+          different colors to indicate their file type.  The color
+          definitions are taken from the value of the 'LS_COLORS'
+          environment variable.  The default is 'off'.
+
+     'comment-begin'
+          The string to insert at the beginning of the line when the
+          'insert-comment' command is executed.  The default value is
+          '"#"'.
+
+     'completion-display-width'
+          The number of screen columns used to display possible matches
+          when performing completion.  The value is ignored if it is
+          less than 0 or greater than the terminal screen width.  A
+          value of 0 will cause matches to be displayed one per line.
+          The default value is -1.
+
+     'completion-ignore-case'
+          If set to 'on', Readline performs filename matching and
+          completion in a case-insensitive fashion.  The default value
+          is 'off'.
+
+     'completion-map-case'
+          If set to 'on', and COMPLETION-IGNORE-CASE is enabled,
+          Readline treats hyphens ('-') and underscores ('_') as
+          equivalent when performing case-insensitive filename matching
+          and completion.  The default value is 'off'.
+
+     'completion-prefix-display-length'
+          The length in characters of the common prefix of a list of
+          possible completions that is displayed without modification.
+          When set to a value greater than zero, common prefixes longer
+          than this value are replaced with an ellipsis when displaying
+          possible completions.
+
+     'completion-query-items'
+          The number of possible completions that determines when the
+          user is asked whether the list of possibilities should be
+          displayed.  If the number of possible completions is greater
+          than or equal to this value, Readline will ask whether or not
+          the user wishes to view them; otherwise, they are simply
+          listed.  This variable must be set to an integer value greater
+          than or equal to zero.  A zero value means Readline should
+          never ask; negative values are treated as zero.  The default
+          limit is '100'.
+
+     'convert-meta'
+          If set to 'on', Readline will convert characters with the
+          eighth bit set to an ASCII key sequence by stripping the
+          eighth bit and prefixing an <ESC> character, converting them
+          to a meta-prefixed key sequence.  The default value is 'on',
+          but will be set to 'off' if the locale is one that contains
+          eight-bit characters.  This variable is dependent on the
+          'LC_CTYPE' locale category, and may change if the locale is
+          changed.
+
+     'disable-completion'
+          If set to 'On', Readline will inhibit word completion.
+          Completion characters will be inserted into the line as if
+          they had been mapped to 'self-insert'.  The default is 'off'.
+
+     'echo-control-characters'
+          When set to 'on', on operating systems that indicate they
+          support it, Readline echoes a character corresponding to a
+          signal generated from the keyboard.  The default is 'on'.
+
+     'editing-mode'
+          The 'editing-mode' variable controls which default set of key
+          bindings is used.  By default, Readline starts up in Emacs
+          editing mode, where the keystrokes are most similar to Emacs.
+          This variable can be set to either 'emacs' or 'vi'.
+
+     'emacs-mode-string'
+          If the SHOW-MODE-IN-PROMPT variable is enabled, this string is
+          displayed immediately before the last line of the primary
+          prompt when emacs editing mode is active.  The value is
+          expanded like a key binding, so the standard set of meta- and
+          control prefixes and backslash escape sequences is available.
+          Use the '\1' and '\2' escapes to begin and end sequences of
+          non-printing characters, which can be used to embed a terminal
+          control sequence into the mode string.  The default is '@'.
+
+     'enable-active-region'
+          The "point" is the current cursor position, and "mark" refers
+          to a saved cursor position (*note Commands For Moving::).  The
+          text between the point and mark is referred to as the
+          "region".  When this variable is set to 'On', Readline allows
+          certain commands to designate the region as "active".  When
+          the region is active, Readline highlights the text in the
+          region using the value of the 'active-region-start-color',
+          which defaults to the string that enables the terminal's
+          standout mode.  The active region shows the text inserted by
+          bracketed-paste and any matching text found by incremental and
+          non-incremental history searches.  The default is 'On'.
+
+     'enable-bracketed-paste'
+          When set to 'On', Readline configures the terminal to insert
+          each paste into the editing buffer as a single string of
+          characters, instead of treating each character as if it had
+          been read from the keyboard.  This is called putting the
+          terminal into "bracketed paste mode"; it prevents Readline
+          from executing any editing commands bound to key sequences
+          appearing in the pasted text.  The default is 'On'.
+
+     'enable-keypad'
+          When set to 'on', Readline will try to enable the application
+          keypad when it is called.  Some systems need this to enable
+          the arrow keys.  The default is 'off'.
+
+     'enable-meta-key'
+          When set to 'on', Readline will try to enable any meta
+          modifier key the terminal claims to support when it is called.
+          On many terminals, the meta key is used to send eight-bit
+          characters.  The default is 'on'.
+
+     'expand-tilde'
+          If set to 'on', tilde expansion is performed when Readline
+          attempts word completion.  The default is 'off'.
+
+     'history-preserve-point'
+          If set to 'on', the history code attempts to place the point
+          (the current cursor position) at the same location on each
+          history line retrieved with 'previous-history' or
+          'next-history'.  The default is 'off'.
+
+     'history-size'
+          Set the maximum number of history entries saved in the history
+          list.  If set to zero, any existing history entries are
+          deleted and no new entries are saved.  If set to a value less
+          than zero, the number of history entries is not limited.  By
+          default, the number of history entries is not limited.  If an
+          attempt is made to set HISTORY-SIZE to a non-numeric value,
+          the maximum number of history entries will be set to 500.
+
+     'horizontal-scroll-mode'
+          This variable can be set to either 'on' or 'off'.  Setting it
+          to 'on' means that the text of the lines being edited will
+          scroll horizontally on a single screen line when they are
+          longer than the width of the screen, instead of wrapping onto
+          a new screen line.  This variable is automatically set to 'on'
+          for terminals of height 1.  By default, this variable is set
+          to 'off'.
+
+     'input-meta'
+          If set to 'on', Readline will enable eight-bit input (it will
+          not clear the eighth bit in the characters it reads),
+          regardless of what the terminal claims it can support.  The
+          default value is 'off', but Readline will set it to 'on' if
+          the locale contains eight-bit characters.  The name
+          'meta-flag' is a synonym for this variable.  This variable is
+          dependent on the 'LC_CTYPE' locale category, and may change if
+          the locale is changed.
+
+     'isearch-terminators'
+          The string of characters that should terminate an incremental
+          search without subsequently executing the character as a
+          command (*note Searching::).  If this variable has not been
+          given a value, the characters <ESC> and 'C-J' will terminate
+          an incremental search.
+
+     'keymap'
+          Sets Readline's idea of the current keymap for key binding
+          commands.  Built-in 'keymap' names are 'emacs',
+          'emacs-standard', 'emacs-meta', 'emacs-ctlx', 'vi', 'vi-move',
+          'vi-command', and 'vi-insert'.  'vi' is equivalent to
+          'vi-command' ('vi-move' is also a synonym); 'emacs' is
+          equivalent to 'emacs-standard'.  Applications may add
+          additional names.  The default value is 'emacs'.  The value of
+          the 'editing-mode' variable also affects the default keymap.
+
+     'keyseq-timeout'
+          Specifies the duration Readline will wait for a character when
+          reading an ambiguous key sequence (one that can form a
+          complete key sequence using the input read so far, or can take
+          additional input to complete a longer key sequence).  If no
+          input is received within the timeout, Readline will use the
+          shorter but complete key sequence.  Readline uses this value
+          to determine whether or not input is available on the current
+          input source ('rl_instream' by default).  The value is
+          specified in milliseconds, so a value of 1000 means that
+          Readline will wait one second for additional input.  If this
+          variable is set to a value less than or equal to zero, or to a
+          non-numeric value, Readline will wait until another key is
+          pressed to decide which key sequence to complete.  The default
+          value is '500'.
+
+     'mark-directories'
+          If set to 'on', completed directory names have a slash
+          appended.  The default is 'on'.
+
+     'mark-modified-lines'
+          This variable, when set to 'on', causes Readline to display an
+          asterisk ('*') at the start of history lines which have been
+          modified.  This variable is 'off' by default.
+
+     'mark-symlinked-directories'
+          If set to 'on', completed names which are symbolic links to
+          directories have a slash appended (subject to the value of
+          'mark-directories').  The default is 'off'.
+
+     'match-hidden-files'
+          This variable, when set to 'on', causes Readline to match
+          files whose names begin with a '.' (hidden files) when
+          performing filename completion.  If set to 'off', the leading
+          '.' must be supplied by the user in the filename to be
+          completed.  This variable is 'on' by default.
+
+     'menu-complete-display-prefix'
+          If set to 'on', menu completion displays the common prefix of
+          the list of possible completions (which may be empty) before
+          cycling through the list.  The default is 'off'.
+
+     'output-meta'
+          If set to 'on', Readline will display characters with the
+          eighth bit set directly rather than as a meta-prefixed escape
+          sequence.  The default is 'off', but Readline will set it to
+          'on' if the locale contains eight-bit characters.  This
+          variable is dependent on the 'LC_CTYPE' locale category, and
+          may change if the locale is changed.
+
+     'page-completions'
+          If set to 'on', Readline uses an internal 'more'-like pager to
+          display a screenful of possible completions at a time.  This
+          variable is 'on' by default.
+
+     'print-completions-horizontally'
+          If set to 'on', Readline will display completions with matches
+          sorted horizontally in alphabetical order, rather than down
+          the screen.  The default is 'off'.
+
+     'revert-all-at-newline'
+          If set to 'on', Readline will undo all changes to history
+          lines before returning when 'accept-line' is executed.  By
+          default, history lines may be modified and retain individual
+          undo lists across calls to 'readline()'.  The default is
+          'off'.
+
+     'show-all-if-ambiguous'
+          This alters the default behavior of the completion functions.
+          If set to 'on', words which have more than one possible
+          completion cause the matches to be listed immediately instead
+          of ringing the bell.  The default value is 'off'.
+
+     'show-all-if-unmodified'
+          This alters the default behavior of the completion functions
+          in a fashion similar to SHOW-ALL-IF-AMBIGUOUS.  If set to
+          'on', words which have more than one possible completion
+          without any possible partial completion (the possible
+          completions don't share a common prefix) cause the matches to
+          be listed immediately instead of ringing the bell.  The
+          default value is 'off'.
+
+     'show-mode-in-prompt'
+          If set to 'on', add a string to the beginning of the prompt
+          indicating the editing mode: emacs, vi command, or vi
+          insertion.  The mode strings are user-settable (e.g.,
+          EMACS-MODE-STRING).  The default value is 'off'.
+
+     'skip-completed-text'
+          If set to 'on', this alters the default completion behavior
+          when inserting a single match into the line.  It's only active
+          when performing completion in the middle of a word.  If
+          enabled, Readline does not insert characters from the
+          completion that match characters after point in the word being
+          completed, so portions of the word following the cursor are
+          not duplicated.  For instance, if this is enabled, attempting
+          completion when the cursor is after the 'e' in 'Makefile' will
+          result in 'Makefile' rather than 'Makefilefile', assuming
+          there is a single possible completion.  The default value is
+          'off'.
+
+     'vi-cmd-mode-string'
+          If the SHOW-MODE-IN-PROMPT variable is enabled, this string is
+          displayed immediately before the last line of the primary
+          prompt when vi editing mode is active and in command mode.
+          The value is expanded like a key binding, so the standard set
+          of meta- and control prefixes and backslash escape sequences
+          is available.  Use the '\1' and '\2' escapes to begin and end
+          sequences of non-printing characters, which can be used to
+          embed a terminal control sequence into the mode string.  The
+          default is '(cmd)'.
+
+     'vi-ins-mode-string'
+          If the SHOW-MODE-IN-PROMPT variable is enabled, this string is
+          displayed immediately before the last line of the primary
+          prompt when vi editing mode is active and in insertion mode.
+          The value is expanded like a key binding, so the standard set
+          of meta- and control prefixes and backslash escape sequences
+          is available.  Use the '\1' and '\2' escapes to begin and end
+          sequences of non-printing characters, which can be used to
+          embed a terminal control sequence into the mode string.  The
+          default is '(ins)'.
+
+     'visible-stats'
+          If set to 'on', a character denoting a file's type is appended
+          to the filename when listing possible completions.  The
+          default is 'off'.
+
+Key Bindings
+     The syntax for controlling key bindings in the init file is simple.
+     First you need to find the name of the command that you want to
+     change.  The following sections contain tables of the command name,
+     the default keybinding, if any, and a short description of what the
+     command does.
+
+     Once you know the name of the command, simply place on a line in
+     the init file the name of the key you wish to bind the command to,
+     a colon, and then the name of the command.  There can be no space
+     between the key name and the colon - that will be interpreted as
+     part of the key name.  The name of the key can be expressed in
+     different ways, depending on what you find most comfortable.
+
+     In addition to command names, Readline allows keys to be bound to a
+     string that is inserted when the key is pressed (a MACRO).
+
+     The 'bind -p' command displays Readline function names and bindings
+     in a format that can be put directly into an initialization file.
+     *Note Bash Builtins::.
+
+     KEYNAME: FUNCTION-NAME or MACRO
+          KEYNAME is the name of a key spelled out in English.  For
+          example:
+               Control-u: universal-argument
+               Meta-Rubout: backward-kill-word
+               Control-o: "> output"
+
+          In the example above, 'C-u' is bound to the function
+          'universal-argument', 'M-DEL' is bound to the function
+          'backward-kill-word', and 'C-o' is bound to run the macro
+          expressed on the right hand side (that is, to insert the text
+          '> output' into the line).
+
+          A number of symbolic character names are recognized while
+          processing this key binding syntax: DEL, ESC, ESCAPE, LFD,
+          NEWLINE, RET, RETURN, RUBOUT, SPACE, SPC, and TAB.
+
+     "KEYSEQ": FUNCTION-NAME or MACRO
+          KEYSEQ differs from KEYNAME above in that strings denoting an
+          entire key sequence can be specified, by placing the key
+          sequence in double quotes.  Some GNU Emacs style key escapes
+          can be used, as in the following example, but the special
+          character names are not recognized.
+
+               "\C-u": universal-argument
+               "\C-x\C-r": re-read-init-file
+               "\e[11~": "Function Key 1"
+
+          In the above example, 'C-u' is again bound to the function
+          'universal-argument' (just as it was in the first example),
+          ''C-x' 'C-r'' is bound to the function 're-read-init-file',
+          and '<ESC> <[> <1> <1> <~>' is bound to insert the text
+          'Function Key 1'.
+
+     The following GNU Emacs style escape sequences are available when
+     specifying key sequences:
+
+     '\C-'
+          control prefix
+     '\M-'
+          meta prefix
+     '\e'
+          an escape character
+     '\\'
+          backslash
+     '\"'
+          <">, a double quotation mark
+     '\''
+          <'>, a single quote or apostrophe
+
+     In addition to the GNU Emacs style escape sequences, a second set
+     of backslash escapes is available:
+
+     '\a'
+          alert (bell)
+     '\b'
+          backspace
+     '\d'
+          delete
+     '\f'
+          form feed
+     '\n'
+          newline
+     '\r'
+          carriage return
+     '\t'
+          horizontal tab
+     '\v'
+          vertical tab
+     '\NNN'
+          the eight-bit character whose value is the octal value NNN
+          (one to three digits)
+     '\xHH'
+          the eight-bit character whose value is the hexadecimal value
+          HH (one or two hex digits)
+
+     When entering the text of a macro, single or double quotes must be
+     used to indicate a macro definition.  Unquoted text is assumed to
+     be a function name.  In the macro body, the backslash escapes
+     described above are expanded.  Backslash will quote any other
+     character in the macro text, including '"' and '''.  For example,
+     the following binding will make ''C-x' \' insert a single '\' into
+     the line:
+          "\C-x\\": "\\"

+
+8.3.2 Conditional Init Constructs
+---------------------------------
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key bindings and
+variable settings to be performed as the result of tests.  There are
+four parser directives used.
+
+'$if'
+     The '$if' construct allows bindings to be made based on the editing
+     mode, the terminal being used, or the application using Readline.
+     The text of the test, after any comparison operator, extends to the
+     end of the line; unless otherwise noted, no characters are required
+     to isolate it.
+
+     'mode'
+          The 'mode=' form of the '$if' directive is used to test
+          whether Readline is in 'emacs' or 'vi' mode.  This may be used
+          in conjunction with the 'set keymap' command, for instance, to
+          set bindings in the 'emacs-standard' and 'emacs-ctlx' keymaps
+          only if Readline is starting out in 'emacs' mode.
+
+     'term'
+          The 'term=' form may be used to include terminal-specific key
+          bindings, perhaps to bind the key sequences output by the
+          terminal's function keys.  The word on the right side of the
+          '=' is tested against both the full name of the terminal and
+          the portion of the terminal name before the first '-'.  This
+          allows 'sun' to match both 'sun' and 'sun-cmd', for instance.
+
+     'version'
+          The 'version' test may be used to perform comparisons against
+          specific Readline versions.  The 'version' expands to the
+          current Readline version.  The set of comparison operators
+          includes '=' (and '=='), '!=', '<=', '>=', '<', and '>'.  The
+          version number supplied on the right side of the operator
+          consists of a major version number, an optional decimal point,
+          and an optional minor version (e.g., '7.1').  If the minor
+          version is omitted, it is assumed to be '0'.  The operator may
+          be separated from the string 'version' and from the version
+          number argument by whitespace.  The following example sets a
+          variable if the Readline version being used is 7.0 or newer:
+               $if version >= 7.0
+               set show-mode-in-prompt on
+               $endif
+
+     'application'
+          The APPLICATION construct is used to include
+          application-specific settings.  Each program using the
+          Readline library sets the APPLICATION NAME, and you can test
+          for a particular value.  This could be used to bind key
+          sequences to functions useful for a specific program.  For
+          instance, the following command adds a key sequence that
+          quotes the current or previous word in Bash:
+               $if Bash
+               # Quote the current or previous word
+               "\C-xq": "\eb\"\ef\""
+               $endif
+
+     'variable'
+          The VARIABLE construct provides simple equality tests for
+          Readline variables and values.  The permitted comparison
+          operators are '=', '==', and '!='.  The variable name must be
+          separated from the comparison operator by whitespace; the
+          operator may be separated from the value on the right hand
+          side by whitespace.  Both string and boolean variables may be
+          tested.  Boolean variables must be tested against the values
+          ON and OFF.  The following example is equivalent to the
+          'mode=emacs' test described above:
+               $if editing-mode == emacs
+               set show-mode-in-prompt on
+               $endif
+
+'$endif'
+     This command, as seen in the previous example, terminates an '$if'
+     command.
+
+'$else'
+     Commands in this branch of the '$if' directive are executed if the
+     test fails.
+
+'$include'
+     This directive takes a single filename as an argument and reads
+     commands and bindings from that file.  For example, the following
+     directive reads from '/etc/inputrc':
+          $include /etc/inputrc

+
+* Commands For Moving::		Moving about the line.
+* Commands For History::	Getting at previous lines.
+* Commands For Text::		Commands for changing text.
+* Commands For Killing::	Commands for killing and yanking.
+* Numeric Arguments::		Specifying numeric arguments, repeat counts.
+* Commands For Completion::	Getting Readline to do the typing for you.
+* Keyboard Macros::		Saving and re-executing typed characters
+* Miscellaneous Commands::	Other miscellaneous commands.
+
+This section describes Readline commands that may be bound to key
+sequences.  You can list your key bindings by executing 'bind -P' or,
+for a more terse format, suitable for an INPUTRC file, 'bind -p'.
+(*Note Bash Builtins::.)  Command names without an accompanying key
+sequence are unbound by default.
+
+   In the following descriptions, "point" refers to the current cursor
+position, and "mark" refers to a cursor position saved by the 'set-mark'
+command.  The text between the point and mark is referred to as the
+"region".

+
+8.4.2 Commands For Manipulating The History
+-------------------------------------------
+
+'accept-line (Newline or Return)'
+     Accept the line regardless of where the cursor is.  If this line is
+     non-empty, add it to the history list according to the setting of
+     the 'HISTCONTROL' and 'HISTIGNORE' variables.  If this line is a
+     modified history line, then restore the history line to its
+     original state.
+
+'previous-history (C-p)'
+     Move 'back' through the history list, fetching the previous
+     command.
+
+'next-history (C-n)'
+     Move 'forward' through the history list, fetching the next command.
+
+'beginning-of-history (M-<)'
+     Move to the first line in the history.
+
+'end-of-history (M->)'
+     Move to the end of the input history, i.e., the line currently
+     being entered.
+
+'reverse-search-history (C-r)'
+     Search backward starting at the current line and moving 'up'
+     through the history as necessary.  This is an incremental search.
+     This command sets the region to the matched text and activates the
+     mark.
+
+'forward-search-history (C-s)'
+     Search forward starting at the current line and moving 'down'
+     through the history as necessary.  This is an incremental search.
+     This command sets the region to the matched text and activates the
+     mark.
+
+'non-incremental-reverse-search-history (M-p)'
+     Search backward starting at the current line and moving 'up'
+     through the history as necessary using a non-incremental search for
+     a string supplied by the user.  The search string may match
+     anywhere in a history line.
+
+'non-incremental-forward-search-history (M-n)'
+     Search forward starting at the current line and moving 'down'
+     through the history as necessary using a non-incremental search for
+     a string supplied by the user.  The search string may match
+     anywhere in a history line.
+
+'history-search-forward ()'
+     Search forward through the history for the string of characters
+     between the start of the current line and the point.  The search
+     string must match at the beginning of a history line.  This is a
+     non-incremental search.  By default, this command is unbound.
+
+'history-search-backward ()'
+     Search backward through the history for the string of characters
+     between the start of the current line and the point.  The search
+     string must match at the beginning of a history line.  This is a
+     non-incremental search.  By default, this command is unbound.
+
+'history-substring-search-forward ()'
+     Search forward through the history for the string of characters
+     between the start of the current line and the point.  The search
+     string may match anywhere in a history line.  This is a
+     non-incremental search.  By default, this command is unbound.
+
+'history-substring-search-backward ()'
+     Search backward through the history for the string of characters
+     between the start of the current line and the point.  The search
+     string may match anywhere in a history line.  This is a
+     non-incremental search.  By default, this command is unbound.
+
+'yank-nth-arg (M-C-y)'
+     Insert the first argument to the previous command (usually the
+     second word on the previous line) at point.  With an argument N,
+     insert the Nth word from the previous command (the words in the
+     previous command begin with word 0).  A negative argument inserts
+     the Nth word from the end of the previous command.  Once the
+     argument N is computed, the argument is extracted as if the '!N'
+     history expansion had been specified.
+
+'yank-last-arg (M-. or M-_)'
+     Insert last argument to the previous command (the last word of the
+     previous history entry).  With a numeric argument, behave exactly
+     like 'yank-nth-arg'.  Successive calls to 'yank-last-arg' move back
+     through the history list, inserting the last word (or the word
+     specified by the argument to the first call) of each line in turn.
+     Any numeric argument supplied to these successive calls determines
+     the direction to move through the history.  A negative argument
+     switches the direction through the history (back or forward).  The
+     history expansion facilities are used to extract the last argument,
+     as if the '!$' history expansion had been specified.
+
+'operate-and-get-next (C-o)'
+     Accept the current line for return to the calling application as if
+     a newline had been entered, and fetch the next line relative to the
+     current line from the history for editing.  A numeric argument, if
+     supplied, specifies the history entry to use instead of the current
+     line.
+
+'fetch-history ()'
+     With a numeric argument, fetch that entry from the history list and
+     make it the current line.  Without an argument, move back to the
+     first entry in the history list.

+
+8.4.3 Commands For Changing Text
+--------------------------------
+
+'end-of-file (usually C-d)'
+     The character indicating end-of-file as set, for example, by
+     'stty'.  If this character is read when there are no characters on
+     the line, and point is at the beginning of the line, Readline
+     interprets it as the end of input and returns EOF.
+
+'delete-char (C-d)'
+     Delete the character at point.  If this function is bound to the
+     same character as the tty EOF character, as 'C-d' commonly is, see
+     above for the effects.
+
+'backward-delete-char (Rubout)'
+     Delete the character behind the cursor.  A numeric argument means
+     to kill the characters instead of deleting them.
+
+'forward-backward-delete-char ()'
+     Delete the character under the cursor, unless the cursor is at the
+     end of the line, in which case the character behind the cursor is
+     deleted.  By default, this is not bound to a key.
+
+'quoted-insert (C-q or C-v)'
+     Add the next character typed to the line verbatim.  This is how to
+     insert key sequences like 'C-q', for example.
+
+'self-insert (a, b, A, 1, !, ...)'
+     Insert yourself.
+
+'bracketed-paste-begin ()'
+     This function is intended to be bound to the "bracketed paste"
+     escape sequence sent by some terminals, and such a binding is
+     assigned by default.  It allows Readline to insert the pasted text
+     as a single unit without treating each character as if it had been
+     read from the keyboard.  The characters are inserted as if each one
+     was bound to 'self-insert' instead of executing any editing
+     commands.
+
+     Bracketed paste sets the region (the characters between point and
+     the mark) to the inserted text.  It uses the concept of an _active
+     mark_: when the mark is active, Readline redisplay uses the
+     terminal's standout mode to denote the region.
+
+'transpose-chars (C-t)'
+     Drag the character before the cursor forward over the character at
+     the cursor, moving the cursor forward as well.  If the insertion
+     point is at the end of the line, then this transposes the last two
+     characters of the line.  Negative arguments have no effect.
+
+'transpose-words (M-t)'
+     Drag the word before point past the word after point, moving point
+     past that word as well.  If the insertion point is at the end of
+     the line, this transposes the last two words on the line.
+
+'upcase-word (M-u)'
+     Uppercase the current (or following) word.  With a negative
+     argument, uppercase the previous word, but do not move the cursor.
+
+'downcase-word (M-l)'
+     Lowercase the current (or following) word.  With a negative
+     argument, lowercase the previous word, but do not move the cursor.
+
+'capitalize-word (M-c)'
+     Capitalize the current (or following) word.  With a negative
+     argument, capitalize the previous word, but do not move the cursor.
+
+'overwrite-mode ()'
+     Toggle overwrite mode.  With an explicit positive numeric argument,
+     switches to overwrite mode.  With an explicit non-positive numeric
+     argument, switches to insert mode.  This command affects only
+     'emacs' mode; 'vi' mode does overwrite differently.  Each call to
+     'readline()' starts in insert mode.
+
+     In overwrite mode, characters bound to 'self-insert' replace the
+     text at point rather than pushing the text to the right.
+     Characters bound to 'backward-delete-char' replace the character
+     before point with a space.
+
+     By default, this command is unbound.

+
+8.4.4 Killing And Yanking
+-------------------------
+
+'kill-line (C-k)'
+     Kill the text from point to the end of the line.  With a negative
+     numeric argument, kill backward from the cursor to the beginning of
+     the current line.
+
+'backward-kill-line (C-x Rubout)'
+     Kill backward from the cursor to the beginning of the current line.
+     With a negative numeric argument, kill forward from the cursor to
+     the end of the current line.
+
+'unix-line-discard (C-u)'
+     Kill backward from the cursor to the beginning of the current line.
+
+'kill-whole-line ()'
+     Kill all characters on the current line, no matter where point is.
+     By default, this is unbound.
+
+'kill-word (M-d)'
+     Kill from point to the end of the current word, or if between
+     words, to the end of the next word.  Word boundaries are the same
+     as 'forward-word'.
+
+'backward-kill-word (M-<DEL>)'
+     Kill the word behind point.  Word boundaries are the same as
+     'backward-word'.
+
+'shell-kill-word (M-C-d)'
+     Kill from point to the end of the current word, or if between
+     words, to the end of the next word.  Word boundaries are the same
+     as 'shell-forward-word'.
+
+'shell-backward-kill-word ()'
+     Kill the word behind point.  Word boundaries are the same as
+     'shell-backward-word'.
+
+'shell-transpose-words (M-C-t)'
+     Drag the word before point past the word after point, moving point
+     past that word as well.  If the insertion point is at the end of
+     the line, this transposes the last two words on the line.  Word
+     boundaries are the same as 'shell-forward-word' and
+     'shell-backward-word'.
+
+'unix-word-rubout (C-w)'
+     Kill the word behind point, using white space as a word boundary.
+     The killed text is saved on the kill-ring.
+
+'unix-filename-rubout ()'
+     Kill the word behind point, using white space and the slash
+     character as the word boundaries.  The killed text is saved on the
+     kill-ring.
+
+'delete-horizontal-space ()'
+     Delete all spaces and tabs around point.  By default, this is
+     unbound.
+
+'kill-region ()'
+     Kill the text in the current region.  By default, this command is
+     unbound.
+
+'copy-region-as-kill ()'
+     Copy the text in the region to the kill buffer, so it can be yanked
+     right away.  By default, this command is unbound.
+
+'copy-backward-word ()'
+     Copy the word before point to the kill buffer.  The word boundaries
+     are the same as 'backward-word'.  By default, this command is
+     unbound.
+
+'copy-forward-word ()'
+     Copy the word following point to the kill buffer.  The word
+     boundaries are the same as 'forward-word'.  By default, this
+     command is unbound.
+
+'yank (C-y)'
+     Yank the top of the kill ring into the buffer at point.
+
+'yank-pop (M-y)'
+     Rotate the kill-ring, and yank the new top.  You can only do this
+     if the prior command is 'yank' or 'yank-pop'.
+

+
+8.4.5 Specifying Numeric Arguments
+----------------------------------
+
+'digit-argument (M-0, M-1, ... M--)'
+     Add this digit to the argument already accumulating, or start a new
+     argument.  'M--' starts a negative argument.
+
+'universal-argument ()'
+     This is another way to specify an argument.  If this command is
+     followed by one or more digits, optionally with a leading minus
+     sign, those digits define the argument.  If the command is followed
+     by digits, executing 'universal-argument' again ends the numeric
+     argument, but is otherwise ignored.  As a special case, if this
+     command is immediately followed by a character that is neither a
+     digit nor minus sign, the argument count for the next command is
+     multiplied by four.  The argument count is initially one, so
+     executing this function the first time makes the argument count
+     four, a second time makes the argument count sixteen, and so on.
+     By default, this is not bound to a key.

+
+8.4.6 Letting Readline Type For You
+-----------------------------------
+
+'complete (<TAB>)'
+     Attempt to perform completion on the text before point.  The actual
+     completion performed is application-specific.  Bash attempts
+     completion treating the text as a variable (if the text begins with
+     '$'), username (if the text begins with '~'), hostname (if the text
+     begins with '@'), or command (including aliases and functions) in
+     turn.  If none of these produces a match, filename completion is
+     attempted.
+
+'possible-completions (M-?)'
+     List the possible completions of the text before point.  When
+     displaying completions, Readline sets the number of columns used
+     for display to the value of 'completion-display-width', the value
+     of the environment variable 'COLUMNS', or the screen width, in that
+     order.
+
+'insert-completions (M-*)'
+     Insert all completions of the text before point that would have
+     been generated by 'possible-completions'.
+
+'menu-complete ()'
+     Similar to 'complete', but replaces the word to be completed with a
+     single match from the list of possible completions.  Repeated
+     execution of 'menu-complete' steps through the list of possible
+     completions, inserting each match in turn.  At the end of the list
+     of completions, the bell is rung (subject to the setting of
+     'bell-style') and the original text is restored.  An argument of N
+     moves N positions forward in the list of matches; a negative
+     argument may be used to move backward through the list.  This
+     command is intended to be bound to <TAB>, but is unbound by
+     default.
+
+'menu-complete-backward ()'
+     Identical to 'menu-complete', but moves backward through the list
+     of possible completions, as if 'menu-complete' had been given a
+     negative argument.
+
+'delete-char-or-list ()'
+     Deletes the character under the cursor if not at the beginning or
+     end of the line (like 'delete-char').  If at the end of the line,
+     behaves identically to 'possible-completions'.  This command is
+     unbound by default.
+
+'complete-filename (M-/)'
+     Attempt filename completion on the text before point.
+
+'possible-filename-completions (C-x /)'
+     List the possible completions of the text before point, treating it
+     as a filename.
+
+'complete-username (M-~)'
+     Attempt completion on the text before point, treating it as a
+     username.
+
+'possible-username-completions (C-x ~)'
+     List the possible completions of the text before point, treating it
+     as a username.
+
+'complete-variable (M-$)'
+     Attempt completion on the text before point, treating it as a shell
+     variable.
+
+'possible-variable-completions (C-x $)'
+     List the possible completions of the text before point, treating it
+     as a shell variable.
+
+'complete-hostname (M-@)'
+     Attempt completion on the text before point, treating it as a
+     hostname.
+
+'possible-hostname-completions (C-x @)'
+     List the possible completions of the text before point, treating it
+     as a hostname.
+
+'complete-command (M-!)'
+     Attempt completion on the text before point, treating it as a
+     command name.  Command completion attempts to match the text
+     against aliases, reserved words, shell functions, shell builtins,
+     and finally executable filenames, in that order.
+
+'possible-command-completions (C-x !)'
+     List the possible completions of the text before point, treating it
+     as a command name.
+
+'dynamic-complete-history (M-<TAB>)'
+     Attempt completion on the text before point, comparing the text
+     against lines from the history list for possible completion
+     matches.
+
+'dabbrev-expand ()'
+     Attempt menu completion on the text before point, comparing the
+     text against lines from the history list for possible completion
+     matches.
+
+'complete-into-braces (M-{)'
+     Perform filename completion and insert the list of possible
+     completions enclosed within braces so the list is available to the
+     shell (*note Brace Expansion::).

+8.4.7 Keyboard Macros
+---------------------
+
+'start-kbd-macro (C-x ()'
+     Begin saving the characters typed into the current keyboard macro.
+
+'end-kbd-macro (C-x ))'
+     Stop saving the characters typed into the current keyboard macro
+     and save the definition.
+
+'call-last-kbd-macro (C-x e)'
+     Re-execute the last keyboard macro defined, by making the
+     characters in the macro appear as if typed at the keyboard.
+
+'print-last-kbd-macro ()'
+     Print the last keyboard macro defined in a format suitable for the
+     INPUTRC file.

+
+8.4.8 Some Miscellaneous Commands
+---------------------------------
+
+'re-read-init-file (C-x C-r)'
+     Read in the contents of the INPUTRC file, and incorporate any
+     bindings or variable assignments found there.
+
+'abort (C-g)'
+     Abort the current editing command and ring the terminal's bell
+     (subject to the setting of 'bell-style').
+
+'do-lowercase-version (M-A, M-B, M-X, ...)'
+     If the metafied character X is upper case, run the command that is
+     bound to the corresponding metafied lower case character.  The
+     behavior is undefined if X is already lower case.
+
+'prefix-meta (<ESC>)'
+     Metafy the next character typed.  This is for keyboards without a
+     meta key.  Typing '<ESC> f' is equivalent to typing 'M-f'.
+
+'undo (C-_ or C-x C-u)'
+     Incremental undo, separately remembered for each line.
+
+'revert-line (M-r)'
+     Undo all changes made to this line.  This is like executing the
+     'undo' command enough times to get back to the beginning.
+
+'tilde-expand (M-&)'
+     Perform tilde expansion on the current word.
+
+'set-mark (C-@)'
+     Set the mark to the point.  If a numeric argument is supplied, the
+     mark is set to that position.
+
+'exchange-point-and-mark (C-x C-x)'
+     Swap the point with the mark.  The current cursor position is set
+     to the saved position, and the old cursor position is saved as the
+     mark.
+
+'character-search (C-])'
+     A character is read and point is moved to the next occurrence of
+     that character.  A negative argument searches for previous
+     occurrences.
+
+'character-search-backward (M-C-])'
+     A character is read and point is moved to the previous occurrence
+     of that character.  A negative argument searches for subsequent
+     occurrences.
+
+'skip-csi-sequence ()'
+     Read enough characters to consume a multi-key sequence such as
+     those defined for keys like Home and End.  Such sequences begin
+     with a Control Sequence Indicator (CSI), usually ESC-[.  If this
+     sequence is bound to "\e[", keys producing such sequences will have
+     no effect unless explicitly bound to a Readline command, instead of
+     inserting stray characters into the editing buffer.  This is
+     unbound by default, but usually bound to ESC-[.
+
+'insert-comment (M-#)'
+     Without a numeric argument, the value of the 'comment-begin'
+     variable is inserted at the beginning of the current line.  If a
+     numeric argument is supplied, this command acts as a toggle: if the
+     characters at the beginning of the line do not match the value of
+     'comment-begin', the value is inserted, otherwise the characters in
+     'comment-begin' are deleted from the beginning of the line.  In
+     either case, the line is accepted as if a newline had been typed.
+     The default value of 'comment-begin' causes this command to make
+     the current line a shell comment.  If a numeric argument causes the
+     comment character to be removed, the line will be executed by the
+     shell.
+
+'dump-functions ()'
+     Print all of the functions and their key bindings to the Readline
+     output stream.  If a numeric argument is supplied, the output is
+     formatted in such a way that it can be made part of an INPUTRC
+     file.  This command is unbound by default.
+
+'dump-variables ()'
+     Print all of the settable variables and their values to the
+     Readline output stream.  If a numeric argument is supplied, the
+     output is formatted in such a way that it can be made part of an
+     INPUTRC file.  This command is unbound by default.
+
+'dump-macros ()'
+     Print all of the Readline key sequences bound to macros and the
+     strings they output.  If a numeric argument is supplied, the output
+     is formatted in such a way that it can be made part of an INPUTRC
+     file.  This command is unbound by default.
+
+'spell-correct-word (C-x s)'
+     Perform spelling correction on the current word, treating it as a
+     directory or filename, in the same way as the 'cdspell' shell
+     option.  Word boundaries are the same as those used by
+     'shell-forward-word'.
+
+'glob-complete-word (M-g)'
+     The word before point is treated as a pattern for pathname
+     expansion, with an asterisk implicitly appended.  This pattern is
+     used to generate a list of matching file names for possible
+     completions.
+
+'glob-expand-word (C-x *)'
+     The word before point is treated as a pattern for pathname
+     expansion, and the list of matching file names is inserted,
+     replacing the word.  If a numeric argument is supplied, a '*' is
+     appended before pathname expansion.
+
+'glob-list-expansions (C-x g)'
+     The list of expansions that would have been generated by
+     'glob-expand-word' is displayed, and the line is redrawn.  If a
+     numeric argument is supplied, a '*' is appended before pathname
+     expansion.
+
+'display-shell-version (C-x C-v)'
+     Display version information about the current instance of Bash.
+
+'shell-expand-line (M-C-e)'
+     Expand the line as the shell does.  This performs alias and history
+     expansion as well as all of the shell word expansions (*note Shell
+     Expansions::).
+
+'history-expand-line (M-^)'
+     Perform history expansion on the current line.
+
+'magic-space ()'
+     Perform history expansion on the current line and insert a space
+     (*note History Interaction::).
+
+'alias-expand-line ()'
+     Perform alias expansion on the current line (*note Aliases::).
+
+'history-and-alias-expand-line ()'
+     Perform history and alias expansion on the current line.
+
+'insert-last-argument (M-. or M-_)'
+     A synonym for 'yank-last-arg'.
+
+'edit-and-execute-command (C-x C-e)'
+     Invoke an editor on the current command line, and execute the
+     result as shell commands.  Bash attempts to invoke '$VISUAL',
+     '$EDITOR', and 'emacs' as the editor, in that order.

+8.5 Readline vi Mode
+====================
+
+While the Readline library does not have a full set of 'vi' editing
+functions, it does contain enough to allow simple editing of the line.
+The Readline 'vi' mode behaves as specified in the POSIX standard.
+
+   In order to switch interactively between 'emacs' and 'vi' editing
+modes, use the 'set -o emacs' and 'set -o vi' commands (*note The Set
+Builtin::).  The Readline default is 'emacs' mode.
+
+   When you enter a line in 'vi' mode, you are already placed in
+'insertion' mode, as if you had typed an 'i'.  Pressing <ESC> switches
+you into 'command' mode, where you can edit the text of the line with
+the standard 'vi' movement keys, move to previous history lines with 'k'
+and subsequent lines with 'j', and so forth.

+
+8.6 Programmable Completion
+===========================
+
+When word completion is attempted for an argument to a command for which
+a completion specification (a COMPSPEC) has been defined using the
+'complete' builtin (*note Programmable Completion Builtins::), the
+programmable completion facilities are invoked.
+
+   First, the command name is identified.  If a compspec has been
+defined for that command, the compspec is used to generate the list of
+possible completions for the word.  If the command word is the empty
+string (completion attempted at the beginning of an empty line), any
+compspec defined with the '-E' option to 'complete' is used.  If the
+command word is a full pathname, a compspec for the full pathname is
+searched for first.  If no compspec is found for the full pathname, an
+attempt is made to find a compspec for the portion following the final
+slash.  If those searches do not result in a compspec, any compspec
+defined with the '-D' option to 'complete' is used as the default.  If
+there is no default compspec, Bash attempts alias expansion on the
+command word as a final resort, and attempts to find a compspec for the
+command word from any successful expansion
+
+   Once a compspec has been found, it is used to generate the list of
+matching words.  If a compspec is not found, the default Bash completion
+described above (*note Commands For Completion::) is performed.
+
+   First, the actions specified by the compspec are used.  Only matches
+which are prefixed by the word being completed are returned.  When the
+'-f' or '-d' option is used for filename or directory name completion,
+the shell variable 'FIGNORE' is used to filter the matches.  *Note Bash
+Variables::, for a description of 'FIGNORE'.
+
+   Any completions specified by a filename expansion pattern to the '-G'
+option are generated next.  The words generated by the pattern need not
+match the word being completed.  The 'GLOBIGNORE' shell variable is not
+used to filter the matches, but the 'FIGNORE' shell variable is used.
+
+   Next, the string specified as the argument to the '-W' option is
+considered.  The string is first split using the characters in the 'IFS'
+special variable as delimiters.  Shell quoting is honored within the
+string, in order to provide a mechanism for the words to contain shell
+metacharacters or characters in the value of 'IFS'.  Each word is then
+expanded using brace expansion, tilde expansion, parameter and variable
+expansion, command substitution, and arithmetic expansion, as described
+above (*note Shell Expansions::).  The results are split using the rules
+described above (*note Word Splitting::).  The results of the expansion
+are prefix-matched against the word being completed, and the matching
+words become the possible completions.
+
+   After these matches have been generated, any shell function or
+command specified with the '-F' and '-C' options is invoked.  When the
+command or function is invoked, the 'COMP_LINE', 'COMP_POINT',
+'COMP_KEY', and 'COMP_TYPE' variables are assigned values as described
+above (*note Bash Variables::).  If a shell function is being invoked,
+the 'COMP_WORDS' and 'COMP_CWORD' variables are also set.  When the
+function or command is invoked, the first argument ($1) is the name of
+the command whose arguments are being completed, the second argument
+($2) is the word being completed, and the third argument ($3) is the
+word preceding the word being completed on the current command line.  No
+filtering of the generated completions against the word being completed
+is performed; the function or command has complete freedom in generating
+the matches.
+
+   Any function specified with '-F' is invoked first.  The function may
+use any of the shell facilities, including the 'compgen' and 'compopt'
+builtins described below (*note Programmable Completion Builtins::), to
+generate the matches.  It must put the possible completions in the
+'COMPREPLY' array variable, one per array element.
+
+   Next, any command specified with the '-C' option is invoked in an
+environment equivalent to command substitution.  It should print a list
+of completions, one per line, to the standard output.  Backslash may be
+used to escape a newline, if necessary.
+
+   After all of the possible completions are generated, any filter
+specified with the '-X' option is applied to the list.  The filter is a
+pattern as used for pathname expansion; a '&' in the pattern is replaced
+with the text of the word being completed.  A literal '&' may be escaped
+with a backslash; the backslash is removed before attempting a match.
+Any completion that matches the pattern will be removed from the list.
+A leading '!' negates the pattern; in this case any completion not
+matching the pattern will be removed.  If the 'nocasematch' shell option
+(see the description of 'shopt' in *note The Shopt Builtin::) is
+enabled, the match is performed without regard to the case of alphabetic
+characters.
+
+   Finally, any prefix and suffix specified with the '-P' and '-S'
+options are added to each member of the completion list, and the result
+is returned to the Readline completion code as the list of possible
+completions.
+
+   If the previously-applied actions do not generate any matches, and
+the '-o dirnames' option was supplied to 'complete' when the compspec
+was defined, directory name completion is attempted.
+
+   If the '-o plusdirs' option was supplied to 'complete' when the
+compspec was defined, directory name completion is attempted and any
+matches are added to the results of the other actions.
+
+   By default, if a compspec is found, whatever it generates is returned
+to the completion code as the full set of possible completions.  The
+default Bash completions are not attempted, and the Readline default of
+filename completion is disabled.  If the '-o bashdefault' option was
+supplied to 'complete' when the compspec was defined, the default Bash
+completions are attempted if the compspec generates no matches.  If the
+'-o default' option was supplied to 'complete' when the compspec was
+defined, Readline's default completion will be performed if the compspec
+(and, if attempted, the default Bash completions) generate no matches.
+
+   When a compspec indicates that directory name completion is desired,
+the programmable completion functions force Readline to append a slash
+to completed names which are symbolic links to directories, subject to
+the value of the MARK-DIRECTORIES Readline variable, regardless of the
+setting of the MARK-SYMLINKED-DIRECTORIES Readline variable.
+
+   There is some support for dynamically modifying completions.  This is
+most useful when used in combination with a default completion specified
+with '-D'.  It's possible for shell functions executed as completion
+handlers to indicate that completion should be retried by returning an
+exit status of 124.  If a shell function returns 124, and changes the
+compspec associated with the command on which completion is being
+attempted (supplied as the first argument when the function is
+executed), programmable completion restarts from the beginning, with an
+attempt to find a new compspec for that command.  This allows a set of
+completions to be built dynamically as completion is attempted, rather
+than being loaded all at once.
+
+   For instance, assuming that there is a library of compspecs, each
+kept in a file corresponding to the name of the command, the following
+default completion function would load completions dynamically:
+
+     _completion_loader()
+     {
+         . "/etc/bash_completion.d/$1.sh" >/dev/null 2>&1 && return 124
+     }
+     complete -D -F _completion_loader -o bashdefault -o default

+
+8.7 Programmable Completion Builtins
+====================================
+
+Three builtin commands are available to manipulate the programmable
+completion facilities: one to specify how the arguments to a particular
+command are to be completed, and two to modify the completion as it is
+happening.
+
+'compgen'
+          compgen [OPTION] [WORD]
+
+     Generate possible completion matches for WORD according to the
+     OPTIONs, which may be any option accepted by the 'complete' builtin
+     with the exception of '-p' and '-r', and write the matches to the
+     standard output.  When using the '-F' or '-C' options, the various
+     shell variables set by the programmable completion facilities,
+     while available, will not have useful values.
+
+     The matches will be generated in the same way as if the
+     programmable completion code had generated them directly from a
+     completion specification with the same flags.  If WORD is
+     specified, only those completions matching WORD will be displayed.
+
+     The return value is true unless an invalid option is supplied, or
+     no matches were generated.
+
+'complete'
+          complete [-abcdefgjksuv] [-o COMP-OPTION] [-DEI] [-A ACTION] [-G GLOBPAT]
+          [-W WORDLIST] [-F FUNCTION] [-C COMMAND] [-X FILTERPAT]
+          [-P PREFIX] [-S SUFFIX] NAME [NAME ...]
+          complete -pr [-DEI] [NAME ...]
+
+     Specify how arguments to each NAME should be completed.  If the
+     '-p' option is supplied, or if no options are supplied, existing
+     completion specifications are printed in a way that allows them to
+     be reused as input.  The '-r' option removes a completion
+     specification for each NAME, or, if no NAMEs are supplied, all
+     completion specifications.  The '-D' option indicates that other
+     supplied options and actions should apply to the "default" command
+     completion; that is, completion attempted on a command for which no
+     completion has previously been defined.  The '-E' option indicates
+     that other supplied options and actions should apply to "empty"
+     command completion; that is, completion attempted on a blank line.
+     The '-I' option indicates that other supplied options and actions
+     should apply to completion on the initial non-assignment word on
+     the line, or after a command delimiter such as ';' or '|', which is
+     usually command name completion.  If multiple options are supplied,
+     the '-D' option takes precedence over '-E', and both take
+     precedence over '-I'.  If any of '-D', '-E', or '-I' are supplied,
+     any other NAME arguments are ignored; these completions only apply
+     to the case specified by the option.
+
+     The process of applying these completion specifications when word
+     completion is attempted is described above (*note Programmable
+     Completion::).
+
+     Other options, if specified, have the following meanings.  The
+     arguments to the '-G', '-W', and '-X' options (and, if necessary,
+     the '-P' and '-S' options) should be quoted to protect them from
+     expansion before the 'complete' builtin is invoked.
+
+     '-o COMP-OPTION'
+          The COMP-OPTION controls several aspects of the compspec's
+          behavior beyond the simple generation of completions.
+          COMP-OPTION may be one of:
+
+          'bashdefault'
+               Perform the rest of the default Bash completions if the
+               compspec generates no matches.
+
+          'default'
+               Use Readline's default filename completion if the
+               compspec generates no matches.
+
+          'dirnames'
+               Perform directory name completion if the compspec
+               generates no matches.
+
+          'filenames'
+               Tell Readline that the compspec generates filenames, so
+               it can perform any filename-specific processing (like
+               adding a slash to directory names, quoting special
+               characters, or suppressing trailing spaces).  This option
+               is intended to be used with shell functions specified
+               with '-F'.
+
+          'noquote'
+               Tell Readline not to quote the completed words if they
+               are filenames (quoting filenames is the default).
+
+          'nosort'
+               Tell Readline not to sort the list of possible
+               completions alphabetically.
+
+          'nospace'
+               Tell Readline not to append a space (the default) to
+               words completed at the end of the line.
+
+          'plusdirs'
+               After any matches defined by the compspec are generated,
+               directory name completion is attempted and any matches
+               are added to the results of the other actions.
+
+     '-A ACTION'
+          The ACTION may be one of the following to generate a list of
+          possible completions:
+
+          'alias'
+               Alias names.  May also be specified as '-a'.
+
+          'arrayvar'
+               Array variable names.
+
+          'binding'
+               Readline key binding names (*note Bindable Readline
+               Commands::).
+
+          'builtin'
+               Names of shell builtin commands.  May also be specified
+               as '-b'.
+
+          'command'
+               Command names.  May also be specified as '-c'.
+
+          'directory'
+               Directory names.  May also be specified as '-d'.
+
+          'disabled'
+               Names of disabled shell builtins.
+
+          'enabled'
+               Names of enabled shell builtins.
+
+          'export'
+               Names of exported shell variables.  May also be specified
+               as '-e'.
+
+          'file'
+               File names.  May also be specified as '-f'.
+
+          'function'
+               Names of shell functions.
+
+          'group'
+               Group names.  May also be specified as '-g'.
+
+          'helptopic'
+               Help topics as accepted by the 'help' builtin (*note Bash
+               Builtins::).
+
+          'hostname'
+               Hostnames, as taken from the file specified by the
+               'HOSTFILE' shell variable (*note Bash Variables::).
+
+          'job'
+               Job names, if job control is active.  May also be
+               specified as '-j'.
+
+          'keyword'
+               Shell reserved words.  May also be specified as '-k'.
+
+          'running'
+               Names of running jobs, if job control is active.
+
+          'service'
+               Service names.  May also be specified as '-s'.
+
+          'setopt'
+               Valid arguments for the '-o' option to the 'set' builtin
+               (*note The Set Builtin::).
+
+          'shopt'
+               Shell option names as accepted by the 'shopt' builtin
+               (*note Bash Builtins::).
+
+          'signal'
+               Signal names.
+
+          'stopped'
+               Names of stopped jobs, if job control is active.
+
+          'user'
+               User names.  May also be specified as '-u'.
+
+          'variable'
+               Names of all shell variables.  May also be specified as
+               '-v'.
+
+     '-C COMMAND'
+          COMMAND is executed in a subshell environment, and its output
+          is used as the possible completions.  Arguments are passed as
+          with the '-F' option.
+
+     '-F FUNCTION'
+          The shell function FUNCTION is executed in the current shell
+          environment.  When it is executed, $1 is the name of the
+          command whose arguments are being completed, $2 is the word
+          being completed, and $3 is the word preceding the word being
+          completed, as described above (*note Programmable
+          Completion::).  When it finishes, the possible completions are
+          retrieved from the value of the 'COMPREPLY' array variable.
+
+     '-G GLOBPAT'
+          The filename expansion pattern GLOBPAT is expanded to generate
+          the possible completions.
+
+     '-P PREFIX'
+          PREFIX is added at the beginning of each possible completion
+          after all other options have been applied.
+
+     '-S SUFFIX'
+          SUFFIX is appended to each possible completion after all other
+          options have been applied.
+
+     '-W WORDLIST'
+          The WORDLIST is split using the characters in the 'IFS'
+          special variable as delimiters, and each resultant word is
+          expanded.  The possible completions are the members of the
+          resultant list which match the word being completed.
+
+     '-X FILTERPAT'
+          FILTERPAT is a pattern as used for filename expansion.  It is
+          applied to the list of possible completions generated by the
+          preceding options and arguments, and each completion matching
+          FILTERPAT is removed from the list.  A leading '!' in
+          FILTERPAT negates the pattern; in this case, any completion
+          not matching FILTERPAT is removed.
+
+     The return value is true unless an invalid option is supplied, an
+     option other than '-p' or '-r' is supplied without a NAME argument,
+     an attempt is made to remove a completion specification for a NAME
+     for which no specification exists, or an error occurs adding a
+     completion specification.
+
+'compopt'
+          compopt [-o OPTION] [-DEI] [+o OPTION] [NAME]
+     Modify completion options for each NAME according to the OPTIONs,
+     or for the currently-executing completion if no NAMEs are supplied.
+     If no OPTIONs are given, display the completion options for each
+     NAME or the current completion.  The possible values of OPTION are
+     those valid for the 'complete' builtin described above.  The '-D'
+     option indicates that other supplied options should apply to the
+     "default" command completion; that is, completion attempted on a
+     command for which no completion has previously been defined.  The
+     '-E' option indicates that other supplied options should apply to
+     "empty" command completion; that is, completion attempted on a
+     blank line.  The '-I' option indicates that other supplied options
+     should apply to completion on the initial non-assignment word on
+     the line, or after a command delimiter such as ';' or '|', which is
+     usually command name completion.
+
+     If multiple options are supplied, the '-D' option takes precedence
+     over '-E', and both take precedence over '-I'
+
+     The return value is true unless an invalid option is supplied, an
+     attempt is made to modify the options for a NAME for which no
+     completion specification exists, or an output error occurs.

+
+8.8 A Programmable Completion Example
+=====================================
+
+The most common way to obtain additional completion functionality beyond
+the default actions 'complete' and 'compgen' provide is to use a shell
+function and bind it to a particular command using 'complete -F'.
+
+   The following function provides completions for the 'cd' builtin.  It
+is a reasonably good example of what shell functions must do when used
+for completion.  This function uses the word passed as '$2' to determine
+the directory name to complete.  You can also use the 'COMP_WORDS' array
+variable; the current word is indexed by the 'COMP_CWORD' variable.
+
+   The function relies on the 'complete' and 'compgen' builtins to do
+much of the work, adding only the things that the Bash 'cd' does beyond
+accepting basic directory names: tilde expansion (*note Tilde
+Expansion::), searching directories in $CDPATH, which is described above
+(*note Bourne Shell Builtins::), and basic support for the 'cdable_vars'
+shell option (*note The Shopt Builtin::).  '_comp_cd' modifies the value
+of IFS so that it contains only a newline to accommodate file names
+containing spaces and tabs - 'compgen' prints the possible completions

+
+   Possible completions go into the COMPREPLY array variable, one
+completion per array element.  The programmable completion system
+retrieves the completions from there when the function returns.

+         fi
+
+         return 0
+     }
+
+   We install the completion function using the '-F' option to
+'complete':
+
+     # Tell readline to quote appropriate and append slashes to directories;
+     # use the bash default completion for other arguments
+     complete -o filenames -o nospace -o bashdefault -F _comp_cd cd
+
+Since we'd like Bash and Readline to take care of some of the other
+details for us, we use several other options to tell Bash and Readline
+what to do.  The '-o filenames' option tells Readline that the possible
+completions should be treated as filenames, and quoted appropriately.
+That option will also cause Readline to append a slash to filenames it
+can determine are directories (which is why we might want to extend
+'_comp_cd' to append a slash if we're using directories found via
+CDPATH: Readline can't tell those completions are directories).  The '-o
+nospace' option tells Readline to not append a space character to the
+directory name, in case we want to append to it.  The '-o bashdefault'
+option brings in the rest of the "Bash default" completions - possible
+completions that Bash adds to the default Readline set.  These include
+things like command name completion, variable completion for words
+beginning with '$' or '${', completions containing pathname expansion
+patterns (*note Filename Expansion::), and so on.
+
+   Once installed using 'complete', '_comp_cd' will be called every time
+we attempt word completion for a 'cd' command.
+
+   Many more examples - an extensive collection of completions for most
+of the common GNU, Unix, and Linux commands - are available as part of
+the bash_completion project.  This is installed by default on many
+GNU/Linux distributions.  Originally written by Ian Macdonald, the
+project now lives at <https://github.com/scop/bash-completion/>.  There
+are ports for other systems such as Solaris and Mac OS X.
+
+   An older version of the bash_completion package is distributed with
+bash in the 'examples/complete' subdirectory.

+This chapter describes how to use the GNU History Library interactively,

+File: bash.info,  Node: Bash History Facilities,  Next: Bash History Builtins,  Up: Using History Interactively
+
+9.1 Bash History Facilities
+===========================
+
+When the '-o history' option to the 'set' builtin is enabled (*note The
+Set Builtin::), the shell provides access to the "command history", the
+list of commands previously typed.  The value of the 'HISTSIZE' shell
+variable is used as the number of commands to save in a history list.
+The text of the last '$HISTSIZE' commands (default 500) is saved.  The
+shell stores each command in the history list prior to parameter and
+variable expansion but after history expansion is performed, subject to
+the values of the shell variables 'HISTIGNORE' and 'HISTCONTROL'.
+
+   When the shell starts up, the history is initialized from the file
+named by the 'HISTFILE' variable (default '~/.bash_history').  The file
+named by the value of 'HISTFILE' is truncated, if necessary, to contain
+no more than the number of lines specified by the value of the
+'HISTFILESIZE' variable.  When a shell with history enabled exits, the
+last '$HISTSIZE' lines are copied from the history list to the file
+named by '$HISTFILE'.  If the 'histappend' shell option is set (*note
+Bash Builtins::), the lines are appended to the history file, otherwise
+the history file is overwritten.  If 'HISTFILE' is unset, or if the
+history file is unwritable, the history is not saved.  After saving the
+history, the history file is truncated to contain no more than
+'$HISTFILESIZE' lines.  If 'HISTFILESIZE' is unset, or set to null, a
+non-numeric value, or a numeric value less than zero, the history file
+is not truncated.
+
+   If the 'HISTTIMEFORMAT' is set, the time stamp information associated
+with each history entry is written to the history file, marked with the
+history comment character.  When the history file is read, lines
+beginning with the history comment character followed immediately by a
+digit are interpreted as timestamps for the following history entry.
+
+   The builtin command 'fc' may be used to list or edit and re-execute a
+portion of the history list.  The 'history' builtin may be used to
+display or modify the history list and manipulate the history file.
+When using command-line editing, search commands are available in each
+editing mode that provide access to the history list (*note Commands For
+History::).
+
+   The shell allows control over which commands are saved on the history
+list.  The 'HISTCONTROL' and 'HISTIGNORE' variables may be set to cause
+the shell to save only a subset of the commands entered.  The 'cmdhist'
+shell option, if enabled, causes the shell to attempt to save each line
+of a multi-line command in the same history entry, adding semicolons
+where necessary to preserve syntactic correctness.  The 'lithist' shell
+option causes the shell to save the command with embedded newlines
+instead of semicolons.  The 'shopt' builtin is used to set these
+options.  *Note The Shopt Builtin::, for a description of 'shopt'.
+
+
+File: bash.info,  Node: Bash History Builtins,  Next: History Interaction,  Prev: Bash History Facilities,  Up: Using History Interactively
+
+9.2 Bash History Builtins
+=========================
+
+Bash provides two builtin commands which manipulate the history list and
+history file.
+
+'fc'
+          fc [-e ENAME] [-lnr] [FIRST] [LAST]
+          fc -s [PAT=REP] [COMMAND]
+
+     The first form selects a range of commands from FIRST to LAST from
+     the history list and displays or edits and re-executes them.  Both
+     FIRST and LAST may be specified as a string (to locate the most
+     recent command beginning with that string) or as a number (an index
+     into the history list, where a negative number is used as an offset
+     from the current command number).
+
+     When listing, a FIRST or LAST of 0 is equivalent to -1 and -0 is
+     equivalent to the current command (usually the 'fc' command);
+     otherwise 0 is equivalent to -1 and -0 is invalid.
+
+     If LAST is not specified, it is set to FIRST.  If FIRST is not
+     specified, it is set to the previous command for editing and -16
+     for listing.  If the '-l' flag is given, the commands are listed on
+     standard output.  The '-n' flag suppresses the command numbers when
+     listing.  The '-r' flag reverses the order of the listing.
+     Otherwise, the editor given by ENAME is invoked on a file
+     containing those commands.  If ENAME is not given, the value of the
+     following variable expansion is used: '${FCEDIT:-${EDITOR:-vi}}'.
+     This says to use the value of the 'FCEDIT' variable if set, or the
+     value of the 'EDITOR' variable if that is set, or 'vi' if neither
+     is set.  When editing is complete, the edited commands are echoed
+     and executed.
+
+     In the second form, COMMAND is re-executed after each instance of
+     PAT in the selected command is replaced by REP.  COMMAND is
+     interpreted the same as FIRST above.
+
+     A useful alias to use with the 'fc' command is 'r='fc -s'', so that
+     typing 'r cc' runs the last command beginning with 'cc' and typing
+     'r' re-executes the last command (*note Aliases::).
+
+'history'
+          history [N]
+          history -c
+          history -d OFFSET
+          history -d START-END
+          history [-anrw] [FILENAME]
+          history -ps ARG
+
+     With no options, display the history list with line numbers.  Lines
+     prefixed with a '*' have been modified.  An argument of N lists
+     only the last N lines.  If the shell variable 'HISTTIMEFORMAT' is
+     set and not null, it is used as a format string for STRFTIME to
+     display the time stamp associated with each displayed history
+     entry.  No intervening blank is printed between the formatted time
+     stamp and the history line.
+
+     Options, if supplied, have the following meanings:
+
+     '-c'
+          Clear the history list.  This may be combined with the other
+          options to replace the history list completely.
+
+     '-d OFFSET'
+          Delete the history entry at position OFFSET.  If OFFSET is
+          positive, it should be specified as it appears when the
+          history is displayed.  If OFFSET is negative, it is
+          interpreted as relative to one greater than the last history
+          position, so negative indices count back from the end of the
+          history, and an index of '-1' refers to the current 'history
+          -d' command.
+
+     '-d START-END'
+          Delete the range of history entries between positions START
+          and END, inclusive.  Positive and negative values for START
+          and END are interpreted as described above.
+
+     '-a'
+          Append the new history lines to the history file.  These are
+          history lines entered since the beginning of the current Bash
+          session, but not already appended to the history file.
+
+     '-n'
+          Append the history lines not already read from the history
+          file to the current history list.  These are lines appended to
+          the history file since the beginning of the current Bash
+          session.
+
+     '-r'
+          Read the history file and append its contents to the history
+          list.
+
+     '-w'
+          Write out the current history list to the history file.
+
+     '-p'
+          Perform history substitution on the ARGs and display the
+          result on the standard output, without storing the results in
+          the history list.
+
+     '-s'
+          The ARGs are added to the end of the history list as a single
+          entry.
+
+     If a FILENAME argument is supplied when any of the '-w', '-r',
+     '-a', or '-n' options is used, Bash uses FILENAME as the history
+     file.  If not, then the value of the 'HISTFILE' variable is used.
+
+     The return value is 0 unless an invalid option is encountered, an
+     error occurs while reading or writing the history file, an invalid
+     OFFSET or range is supplied as an argument to '-d', or the history
+     expansion supplied as an argument to '-p' fails.
+
+
+File: bash.info,  Node: History Interaction,  Prev: Bash History Builtins,  Up: Using History Interactively
+
+9.3 History Expansion
+=====================
+
+The History library provides a history expansion feature that is similar
+to the history expansion provided by 'csh'.  This section describes the
+syntax used to manipulate the history information.
+
+   History expansions introduce words from the history list into the
+input stream, making it easy to repeat commands, insert the arguments to
+a previous command into the current input line, or fix errors in
+previous commands quickly.
+
+   History expansion is performed immediately after a complete line is
+read, before the shell breaks it into words, and is performed on each
+line individually.  Bash attempts to inform the history expansion
+functions about quoting still in effect from previous lines.
+
+   History expansion takes place in two parts.  The first is to
+determine which line from the history list should be used during
+substitution.  The second is to select portions of that line for
+inclusion into the current one.  The line selected from the history is
+called the "event", and the portions of that line that are acted upon
+are called "words".  Various "modifiers" are available to manipulate the
+selected words.  The line is broken into words in the same fashion that
+Bash does, so that several words surrounded by quotes are considered one
+word.  History expansions are introduced by the appearance of the
+history expansion character, which is '!' by default.
+
+   History expansion implements shell-like quoting conventions: a
+backslash can be used to remove the special handling for the next
+character; single quotes enclose verbatim sequences of characters, and
+can be used to inhibit history expansion; and characters enclosed within
+double quotes may be subject to history expansion, since backslash can
+escape the history expansion character, but single quotes may not, since
+they are not treated specially within double quotes.
+
+   When using the shell, only '\' and ''' may be used to escape the
+history expansion character, but the history expansion character is also
+treated as quoted if it immediately precedes the closing double quote in
+a double-quoted string.
+
+   Several shell options settable with the 'shopt' builtin (*note The
+Shopt Builtin::) may be used to tailor the behavior of history
+expansion.  If the 'histverify' shell option is enabled, and Readline is
+being used, history substitutions are not immediately passed to the
+shell parser.  Instead, the expanded line is reloaded into the Readline
+editing buffer for further modification.  If Readline is being used, and
+the 'histreedit' shell option is enabled, a failed history expansion
+will be reloaded into the Readline editing buffer for correction.  The
+'-p' option to the 'history' builtin command may be used to see what a
+history expansion will do before using it.  The '-s' option to the
+'history' builtin may be used to add commands to the end of the history
+list without actually executing them, so that they are available for
+subsequent recall.  This is most useful in conjunction with Readline.
+
+   The shell allows control of the various characters used by the
+history expansion mechanism with the 'histchars' variable, as explained
+above (*note Bash Variables::).  The shell uses the history comment
+character to mark history timestamps when writing the history file.

+
+
+File: bash.info,  Node: Event Designators,  Next: Word Designators,  Up: History Interaction
+
+9.3.1 Event Designators
+-----------------------
+
+An event designator is a reference to a command line entry in the
+history list.  Unless the reference is absolute, events are relative to
+the current position in the history list.
+
+'!'
+     Start a history substitution, except when followed by a space, tab,
+     the end of the line, '=' or '(' (when the 'extglob' shell option is
+     enabled using the 'shopt' builtin).
+
+'!N'
+     Refer to command line N.
+
+'!-N'
+     Refer to the command N lines back.
+
+'!!'
+     Refer to the previous command.  This is a synonym for '!-1'.
+
+'!STRING'
+     Refer to the most recent command preceding the current position in
+     the history list starting with STRING.
+
+'!?STRING[?]'
+     Refer to the most recent command preceding the current position in
+     the history list containing STRING.  The trailing '?' may be
+     omitted if the STRING is followed immediately by a newline.  If
+     STRING is missing, the string from the most recent search is used;
+     it is an error if there is no previous search string.
+
+'^STRING1^STRING2^'
+     Quick Substitution.  Repeat the last command, replacing STRING1
+     with STRING2.  Equivalent to '!!:s^STRING1^STRING2^'.
+
+'!#'
+     The entire command line typed so far.
+
+
+File: bash.info,  Node: Word Designators,  Next: Modifiers,  Prev: Event Designators,  Up: History Interaction
+
+9.3.2 Word Designators
+----------------------
+
+Word designators are used to select desired words from the event.  A ':'
+separates the event specification from the word designator.  It may be
+omitted if the word designator begins with a '^', '$', '*', '-', or '%'.
+Words are numbered from the beginning of the line, with the first word
+being denoted by 0 (zero).  Words are inserted into the current line
+separated by single spaces.
+
+   For example,
+
+'!!'
+     designates the preceding command.  When you type this, the
+     preceding command is repeated in toto.
+
+'!!:$'
+     designates the last argument of the preceding command.  This may be
+     shortened to '!$'.
+
+'!fi:2'
+     designates the second argument of the most recent command starting
+     with the letters 'fi'.
+
+   Here are the word designators:
+
+'0 (zero)'
+     The '0'th word.  For many applications, this is the command word.
+
+'N'
+     The Nth word.
+
+'^'
+     The first argument; that is, word 1.
+
+'$'
+     The last argument.
+
+'%'
+     The first word matched by the most recent '?STRING?' search, if the
+     search string begins with a character that is part of a word.
+
+'X-Y'
+     A range of words; '-Y' abbreviates '0-Y'.
+
+'*'
+     All of the words, except the '0'th.  This is a synonym for '1-$'.
+     It is not an error to use '*' if there is just one word in the
+     event; the empty string is returned in that case.
+
+'X*'
+     Abbreviates 'X-$'
+
+'X-'
+     Abbreviates 'X-$' like 'X*', but omits the last word.  If 'x' is
+     missing, it defaults to 0.
+
+   If a word designator is supplied without an event specification, the
+previous command is used as the event.
+
+
+File: bash.info,  Node: Modifiers,  Prev: Word Designators,  Up: History Interaction
+
+9.3.3 Modifiers
+---------------
+
+After the optional word designator, you can add a sequence of one or
+more of the following modifiers, each preceded by a ':'.  These modify,
+or edit, the word or words selected from the history event.
+
+'h'
+     Remove a trailing pathname component, leaving only the head.
+
+'t'
+     Remove all leading pathname components, leaving the tail.
+
+'r'
+     Remove a trailing suffix of the form '.SUFFIX', leaving the
+     basename.
+
+'e'
+     Remove all but the trailing suffix.
+
+'p'
+     Print the new command but do not execute it.
+
+'q'
+     Quote the substituted words, escaping further substitutions.
+
+'x'
+     Quote the substituted words as with 'q', but break into words at
+     spaces, tabs, and newlines.  The 'q' and 'x' modifiers are mutually
+     exclusive; the last one supplied is used.
+
+'s/OLD/NEW/'
+     Substitute NEW for the first occurrence of OLD in the event line.
+     Any character may be used as the delimiter in place of '/'.  The
+     delimiter may be quoted in OLD and NEW with a single backslash.  If
+     '&' appears in NEW, it is replaced by OLD.  A single backslash will
+     quote the '&'.  If OLD is null, it is set to the last OLD
+     substituted, or, if no previous history substitutions took place,
+     the last STRING in a !?STRING'[?]' search.  If NEW is null, each
+     matching OLD is deleted.  The final delimiter is optional if it is
+     the last character on the input line.
+
+'&'
+     Repeat the previous substitution.
+
+'g'
+'a'
+     Cause changes to be applied over the entire event line.  Used in
+     conjunction with 's', as in 'gs/OLD/NEW/', or with '&'.
+
+'G'
+     Apply the following 's' or '&' modifier once to each word in the
+     event.

+
+10.1 Basic Installation
+=======================
+
+These are installation instructions for Bash.
+
+   The simplest way to compile Bash is:
+
+  1. 'cd' to the directory containing the source code and type
+     './configure' to configure Bash for your system.  If you're using
+     'csh' on an old version of System V, you might need to type 'sh
+     ./configure' instead to prevent 'csh' from trying to execute
+     'configure' itself.
+
+     Running 'configure' takes some time.  While running, it prints
+     messages telling which features it is checking for.
+
+  2. Type 'make' to compile Bash and build the 'bashbug' bug reporting
+     script.
+
+  3. Optionally, type 'make tests' to run the Bash test suite.
+
+  4. Type 'make install' to install 'bash' and 'bashbug'.  This will
+     also install the manual pages and Info file, message translation
+     files, some supplemental documentation, a number of example
+     loadable builtin commands, and a set of header files for developing
+     loadable builtins.  You may need additional privileges to install
+     'bash' to your desired destination, so 'sudo make install' might be
+     required.  More information about controlling the locations where
+     'bash' and other files are installed is below (*note Installation
+     Names::).
+
+   The 'configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a 'Makefile' in each directory of the package
+(the top directory, the 'builtins', 'doc', 'po', and 'support'
+directories, each directory under 'lib', and several others).  It also
+creates a 'config.h' file containing system-dependent definitions.
+Finally, it creates a shell script named 'config.status' that you can
+run in the future to recreate the current configuration, a file
+'config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file 'config.log' containing compiler output
+(useful mainly for debugging 'configure').  If at some point
+'config.cache' contains results you don't want to keep, you may remove
+or edit it.
+
+   To find out more about the options and arguments that the 'configure'
+script understands, type
+
+     bash-4.2$ ./configure --help
+
+at the Bash prompt in your Bash source directory.
+
+   If you want to build Bash in a directory separate from the source
+directory - to build for multiple architectures, for example - just use
+the full path to the configure script.  The following commands will
+build bash in a directory under '/usr/local/build' from the source code
+in '/usr/local/src/bash-4.4':
+
+     mkdir /usr/local/build/bash-4.4
+     cd /usr/local/build/bash-4.4
+     bash /usr/local/src/bash-4.4/configure
+     make
+
+   See *note Compiling For Multiple Architectures:: for more information
+about building in a directory separate from the source.
+
+   If you need to do unusual things to compile Bash, please try to
+figure out how 'configure' could check whether or not to do them, and
+mail diffs or instructions to <bash-maintainers@gnu.org> so they can be
+considered for the next release.
+
+   The file 'configure.ac' is used to create 'configure' by a program
+called Autoconf.  You only need 'configure.ac' if you want to change it
+or regenerate 'configure' using a newer version of Autoconf.  If you do
+this, make sure you are using Autoconf version 2.69 or newer.
+
+   You can remove the program binaries and object files from the source
+code directory by typing 'make clean'.  To also remove the files that
+'configure' created (so you can compile Bash for a different kind of
+computer), type 'make distclean'.

+
+10.2 Compilers and Options
+==========================
+
+Some systems require unusual options for compilation or linking that the
+'configure' script does not know about.  You can give 'configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+   On systems that have the 'env' program, you can do it like this:
+
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+   The configuration process uses GCC to build Bash if it is available.
+
+
+File: bash.info,  Node: Compiling For Multiple Architectures,  Next: Installation Names,  Prev: Compilers and Options,  Up: Installing Bash
+
+10.3 Compiling For Multiple Architectures
+=========================================
+
+You can compile Bash for more than one kind of computer at the same
+time, by placing the object files for each architecture in their own
+directory.  To do this, you must use a version of 'make' that supports
+the 'VPATH' variable, such as GNU 'make'.  'cd' to the directory where
+you want the object files and executables to go and run the 'configure'
+script from the source directory (*note Basic Installation::).  You may
+need to supply the '--srcdir=PATH' argument to tell 'configure' where
+the source files are.  'configure' automatically checks for the source
+code in the directory that 'configure' is in and in '..'.
+
+   If you have to use a 'make' that does not support the 'VPATH'
+variable, you can compile Bash for one architecture at a time in the
+source code directory.  After you have installed Bash for one
+architecture, use 'make distclean' before reconfiguring for another
+architecture.
+
+   Alternatively, if your system supports symbolic links, you can use
+the 'support/mkclone' script to create a build tree which has symbolic
+links back to each file in the source directory.  Here's an example that
+creates a build directory in the current directory from a source
+directory '/usr/gnu/src/bash-2.0':
+
+     bash /usr/gnu/src/bash-2.0/support/mkclone -s /usr/gnu/src/bash-2.0 .
+
+The 'mkclone' script requires Bash, so you must have already built Bash
+for at least one architecture before you can create build directories
+for other architectures.
+
+
+File: bash.info,  Node: Installation Names,  Next: Specifying the System Type,  Prev: Compiling For Multiple Architectures,  Up: Installing Bash
+
+10.4 Installation Names
+=======================
+
+By default, 'make install' will install into '/usr/local/bin',
+'/usr/local/man', etc.; that is, the "installation prefix" defaults to
+'/usr/local'.  You can specify an installation prefix other than
+'/usr/local' by giving 'configure' the option '--prefix=PATH', or by
+specifying a value for the 'prefix' 'make' variable when running 'make
+install' (e.g., 'make install prefix=PATH').  The 'prefix' variable
+provides a default for 'exec_prefix' and other variables used when
+installing bash.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give 'configure' the option '--exec-prefix=PATH', 'make install' will
+use PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   If you would like to change the installation locations for a single
+run, you can specify these variables as arguments to 'make': 'make
+install exec_prefix=/' will install 'bash' and 'bashbug' into '/bin'
+instead of the default '/usr/local/bin'.
+
+   If you want to see the files bash will install and where it will
+install them without changing anything on your system, specify the
+variable 'DESTDIR' as an argument to 'make'.  Its value should be the
+absolute directory path you'd like to use as the root of your sample
+installation tree.  For example,
+
+     mkdir /fs1/bash-install
+     make install DESTDIR=/fs1/bash-install
+
+will install 'bash' into '/fs1/bash-install/usr/local/bin/bash', the
+documentation into directories within
+'/fs1/bash-install/usr/local/share', the example loadable builtins into
+'/fs1/bash-install/usr/local/lib/bash', and so on.  You can use the
+usual 'exec_prefix' and 'prefix' variables to alter the directory paths
+beneath the value of 'DESTDIR'.
+
+   The GNU Makefile standards provide a more complete description of
+these variables and their effects.
+
+
+File: bash.info,  Node: Specifying the System Type,  Next: Sharing Defaults,  Prev: Installation Names,  Up: Installing Bash
+
+10.5 Specifying the System Type
+===============================
+
+There may be some features 'configure' can not figure out automatically,
+but needs to determine by the type of host Bash will run on.  Usually
+'configure' can figure that out, but if it prints a message saying it
+can not guess the host type, give it the '--host=TYPE' option.  'TYPE'
+can either be a short name for the system type, such as 'sun4', or a
+canonical name with three fields: 'CPU-COMPANY-SYSTEM' (e.g.,
+'i386-unknown-freebsd4.2').
+
+   See the file 'support/config.sub' for the possible values of each
+field.
+
+
+File: bash.info,  Node: Sharing Defaults,  Next: Operation Controls,  Prev: Specifying the System Type,  Up: Installing Bash
+
+10.6 Sharing Defaults
+=====================
+
+If you want to set default values for 'configure' scripts to share, you
+can create a site shell script called 'config.site' that gives default
+values for variables like 'CC', 'cache_file', and 'prefix'.  'configure'
+looks for 'PREFIX/share/config.site' if it exists, then
+'PREFIX/etc/config.site' if it exists.  Or, you can set the
+'CONFIG_SITE' environment variable to the location of the site script.
+A warning: the Bash 'configure' looks for a site script, but not all
+'configure' scripts do.
+
+
+File: bash.info,  Node: Operation Controls,  Next: Optional Features,  Prev: Sharing Defaults,  Up: Installing Bash
+
+10.7 Operation Controls
+=======================
+
+'configure' recognizes the following options to control how it operates.
+
+'--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     './config.cache'.  Set FILE to '/dev/null' to disable caching, for
+     debugging 'configure'.
+
+'--help'
+     Print a summary of the options to 'configure', and exit.
+
+'--quiet'
+'--silent'
+'-q'
+     Do not print messages saying which checks are being made.
+
+'--srcdir=DIR'
+     Look for the Bash source code in directory DIR.  Usually
+     'configure' can determine that directory automatically.
+
+'--version'
+     Print the version of Autoconf used to generate the 'configure'
+     script, and exit.
+
+   'configure' also accepts some other, not widely used, boilerplate
+options.  'configure --help' prints the complete list.
+
+
+File: bash.info,  Node: Optional Features,  Prev: Operation Controls,  Up: Installing Bash
+
+10.8 Optional Features
+======================
+
+The Bash 'configure' has a number of '--enable-FEATURE' options, where
+FEATURE indicates an optional part of Bash.  There are also several
+'--with-PACKAGE' options, where PACKAGE is something like 'bash-malloc'
+or 'purify'.  To turn off the default use of a package, use
+'--without-PACKAGE'.  To configure Bash without a feature that is
+enabled by default, use '--disable-FEATURE'.
+
+   Here is a complete list of the '--enable-' and '--with-' options that
+the Bash 'configure' recognizes.
+
+'--with-afs'
+     Define if you are using the Andrew File System from Transarc.
+
+'--with-bash-malloc'
+     Use the Bash version of 'malloc' in the directory 'lib/malloc'.
+     This is not the same 'malloc' that appears in GNU libc, but an
+     older version originally derived from the 4.2 BSD 'malloc'.  This
+     'malloc' is very fast, but wastes some space on each allocation.
+     This option is enabled by default.  The 'NOTES' file contains a
+     list of systems for which this should be turned off, and
+     'configure' disables this option automatically for a number of
+     systems.
+
+'--with-curses'
+     Use the curses library instead of the termcap library.  This should
+     be supplied if your system has an inadequate or incomplete termcap
+     database.
+
+'--with-gnu-malloc'
+     A synonym for '--with-bash-malloc'.
+
+'--with-installed-readline[=PREFIX]'
+     Define this to make Bash link with a locally-installed version of
+     Readline rather than the version in 'lib/readline'.  This works
+     only with Readline 5.0 and later versions.  If PREFIX is 'yes' or
+     not supplied, 'configure' uses the values of the make variables
+     'includedir' and 'libdir', which are subdirectories of 'prefix' by
+     default, to find the installed version of Readline if it is not in
+     the standard system include and library directories.  If PREFIX is
+     'no', Bash links with the version in 'lib/readline'.  If PREFIX is
+     set to any other value, 'configure' treats it as a directory
+     pathname and looks for the installed version of Readline in
+     subdirectories of that directory (include files in PREFIX/'include'
+     and the library in PREFIX/'lib').
+
+'--with-libintl-prefix[=PREFIX]'
+     Define this to make Bash link with a locally-installed version of
+     the libintl library instead of the version in 'lib/intl'.
+
+'--with-libiconv-prefix[=PREFIX]'
+     Define this to make Bash look for libiconv in PREFIX instead of the
+     standard system locations.  There is no version included with Bash.
+
+'--enable-minimal-config'
+     This produces a shell with minimal features, close to the
+     historical Bourne shell.
+
+   There are several '--enable-' options that alter how Bash is
+compiled, linked, and installed, rather than changing run-time features.
+
+'--enable-largefile'
+     Enable support for large files
+     (http://www.unix.org/version2/whatsnew/lfs20mar.html) if the
+     operating system requires special compiler options to build
+     programs which can access large files.  This is enabled by default,
+     if the operating system provides large file support.
+
+'--enable-profiling'
+     This builds a Bash binary that produces profiling information to be
+     processed by 'gprof' each time it is executed.
+
+'--enable-separate-helpfiles'
+     Use external files for the documentation displayed by the 'help'
+     builtin instead of storing the text internally.
+
+'--enable-static-link'
+     This causes Bash to be linked statically, if 'gcc' is being used.
+     This could be used to build a version to use as root's shell.
+
+   The 'minimal-config' option can be used to disable all of the
+following options, but it is processed first, so individual options may
+be enabled using 'enable-FEATURE'.
+
+   All of the following options except for 'alt-array-implementation',
+'disabled-builtins', 'direxpand-default', 'strict-posix-default', and
+'xpg-echo-default' are enabled by default, unless the operating system
+does not provide the necessary support.
+
+'--enable-alias'
+     Allow alias expansion and include the 'alias' and 'unalias'
+     builtins (*note Aliases::).
+
+'--enable-alt-array-implementation'
+     This builds bash using an alternate implementation of arrays (*note
+     Arrays::) that provides faster access at the expense of using more
+     memory (sometimes many times more, depending on how sparse an array
+     is).
+
+'--enable-arith-for-command'
+     Include support for the alternate form of the 'for' command that
+     behaves like the C language 'for' statement (*note Looping
+     Constructs::).
+
+'--enable-array-variables'
+     Include support for one-dimensional array shell variables (*note
+     Arrays::).
+
+'--enable-bang-history'
+     Include support for 'csh'-like history substitution (*note History
+     Interaction::).
+
+'--enable-brace-expansion'
+     Include 'csh'-like brace expansion ( 'b{a,b}c' ==> 'bac bbc' ).
+     See *note Brace Expansion::, for a complete description.
+
+'--enable-casemod-attributes'
+     Include support for case-modifying attributes in the 'declare'
+     builtin and assignment statements.  Variables with the 'uppercase'
+     attribute, for example, will have their values converted to
+     uppercase upon assignment.
+
+'--enable-casemod-expansion'
+     Include support for case-modifying word expansions.
+
+'--enable-command-timing'
+     Include support for recognizing 'time' as a reserved word and for
+     displaying timing statistics for the pipeline following 'time'
+     (*note Pipelines::).  This allows pipelines as well as shell
+     builtins and functions to be timed.
+
+'--enable-cond-command'
+     Include support for the '[[' conditional command.  (*note
+     Conditional Constructs::).
+
+'--enable-cond-regexp'
+     Include support for matching POSIX regular expressions using the
+     '=~' binary operator in the '[[' conditional command.  (*note
+     Conditional Constructs::).
+
+'--enable-coprocesses'
+     Include support for coprocesses and the 'coproc' reserved word
+     (*note Pipelines::).
+
+'--enable-debugger'
+     Include support for the bash debugger (distributed separately).
+
+'--enable-dev-fd-stat-broken'
+     If calling 'stat' on /dev/fd/N returns different results than
+     calling 'fstat' on file descriptor N, supply this option to enable
+     a workaround.  This has implications for conditional commands that
+     test file attributes.
+
+'--enable-direxpand-default'
+     Cause the 'direxpand' shell option (*note The Shopt Builtin::) to
+     be enabled by default when the shell starts.  It is normally
+     disabled by default.
+
+'--enable-directory-stack'
+     Include support for a 'csh'-like directory stack and the 'pushd',
+     'popd', and 'dirs' builtins (*note The Directory Stack::).
+
+'--enable-disabled-builtins'
+     Allow builtin commands to be invoked via 'builtin xxx' even after
+     'xxx' has been disabled using 'enable -n xxx'.  See *note Bash
+     Builtins::, for details of the 'builtin' and 'enable' builtin
+     commands.
+
+'--enable-dparen-arithmetic'
+     Include support for the '((...))' command (*note Conditional
+     Constructs::).
+
+'--enable-extended-glob'
+     Include support for the extended pattern matching features
+     described above under *note Pattern Matching::.
+
+'--enable-extended-glob-default'
+     Set the default value of the 'extglob' shell option described above
+     under *note The Shopt Builtin:: to be enabled.
+
+'--enable-function-import'
+     Include support for importing function definitions exported by
+     another instance of the shell from the environment.  This option is
+     enabled by default.
+
+'--enable-glob-asciirange-default'
+     Set the default value of the 'globasciiranges' shell option
+     described above under *note The Shopt Builtin:: to be enabled.
+     This controls the behavior of character ranges when used in pattern
+     matching bracket expressions.
+
+'--enable-help-builtin'
+     Include the 'help' builtin, which displays help on shell builtins
+     and variables (*note Bash Builtins::).
+
+'--enable-history'
+     Include command history and the 'fc' and 'history' builtin commands
+     (*note Bash History Facilities::).
+
+'--enable-job-control'
+     This enables the job control features (*note Job Control::), if the
+     operating system supports them.
+
+'--enable-multibyte'
+     This enables support for multibyte characters if the operating
+     system provides the necessary support.
+
+'--enable-net-redirections'
+     This enables the special handling of filenames of the form
+     '/dev/tcp/HOST/PORT' and '/dev/udp/HOST/PORT' when used in
+     redirections (*note Redirections::).
+
+'--enable-process-substitution'
+     This enables process substitution (*note Process Substitution::) if
+     the operating system provides the necessary support.
+
+'--enable-progcomp'
+     Enable the programmable completion facilities (*note Programmable
+     Completion::).  If Readline is not enabled, this option has no
+     effect.
+
+'--enable-prompt-string-decoding'
+     Turn on the interpretation of a number of backslash-escaped
+     characters in the '$PS0', '$PS1', '$PS2', and '$PS4' prompt
+     strings.  See *note Controlling the Prompt::, for a complete list
+     of prompt string escape sequences.
+
+'--enable-readline'
+     Include support for command-line editing and history with the Bash
+     version of the Readline library (*note Command Line Editing::).
+
+'--enable-restricted'
+     Include support for a "restricted shell".  If this is enabled,
+     Bash, when called as 'rbash', enters a restricted mode.  See *note
+     The Restricted Shell::, for a description of restricted mode.
+
+'--enable-select'
+     Include the 'select' compound command, which allows the generation
+     of simple menus (*note Conditional Constructs::).
+
+'--enable-single-help-strings'
+     Store the text displayed by the 'help' builtin as a single string
+     for each help topic.  This aids in translating the text to
+     different languages.  You may need to disable this if your compiler
+     cannot handle very long string literals.
+
+'--enable-strict-posix-default'
+     Make Bash POSIX-conformant by default (*note Bash POSIX Mode::).
+
+'--enable-translatable-strings'
+     Enable support for '$"STRING"' translatable strings (*note Locale
+     Translation::).
+
+'--enable-usg-echo-default'
+     A synonym for '--enable-xpg-echo-default'.
+
+'--enable-xpg-echo-default'
+     Make the 'echo' builtin expand backslash-escaped characters by
+     default, without requiring the '-e' option.  This sets the default
+     value of the 'xpg_echo' shell option to 'on', which makes the Bash
+     'echo' behave more like the version specified in the Single Unix
+     Specification, version 3.  *Note Bash Builtins::, for a description
+     of the escape sequences that 'echo' recognizes.
+
+   The file 'config-top.h' contains C Preprocessor '#define' statements
+for options which are not settable from 'configure'.  Some of these are
+not meant to be changed; beware of the consequences if you do.  Read the
+comments associated with each definition for more information about its
+effect.

+
+Appendix B Major Differences From The Bourne Shell
+**************************************************
+
+Bash implements essentially the same grammar, parameter and variable
+expansion, redirection, and quoting as the Bourne Shell.  Bash uses the
+POSIX standard as the specification of how these features are to be
+implemented.  There are some differences between the traditional Bourne
+shell and Bash; this section quickly details the differences of
+significance.  A number of these differences are explained in greater
+depth in previous sections.  This section uses the version of 'sh'
+included in SVR4.2 (the last version of the historical Bourne shell) as
+the baseline reference.
+
+   * Bash is POSIX-conformant, even where the POSIX specification
+     differs from traditional 'sh' behavior (*note Bash POSIX Mode::).
+
+   * Bash has multi-character invocation options (*note Invoking
+     Bash::).
+
+   * Bash has command-line editing (*note Command Line Editing::) and
+     the 'bind' builtin.
+
+   * Bash provides a programmable word completion mechanism (*note
+     Programmable Completion::), and builtin commands 'complete',
+     'compgen', and 'compopt', to manipulate it.
+
+   * Bash has command history (*note Bash History Facilities::) and the
+     'history' and 'fc' builtins to manipulate it.  The Bash history
+     list maintains timestamp information and uses the value of the
+     'HISTTIMEFORMAT' variable to display it.
+
+   * Bash implements 'csh'-like history expansion (*note History
+     Interaction::).
+
+   * Bash has one-dimensional array variables (*note Arrays::), and the
+     appropriate variable expansions and assignment syntax to use them.
+     Several of the Bash builtins take options to act on arrays.  Bash
+     provides a number of built-in array variables.
+
+   * The '$'...'' quoting syntax, which expands ANSI-C backslash-escaped
+     characters in the text between the single quotes, is supported
+     (*note ANSI-C Quoting::).
+
+   * Bash supports the '$"..."' quoting syntax to do locale-specific
+     translation of the characters between the double quotes.  The '-D',
+     '--dump-strings', and '--dump-po-strings' invocation options list
+     the translatable strings found in a script (*note Locale
+     Translation::).
+
+   * Bash implements the '!' keyword to negate the return value of a
+     pipeline (*note Pipelines::).  Very useful when an 'if' statement
+     needs to act only if a test fails.  The Bash '-o pipefail' option
+     to 'set' will cause a pipeline to return a failure status if any
+     command fails.
+
+   * Bash has the 'time' reserved word and command timing (*note
+     Pipelines::).  The display of the timing statistics may be
+     controlled with the 'TIMEFORMAT' variable.
+
+   * Bash implements the 'for (( EXPR1 ; EXPR2 ; EXPR3 ))' arithmetic
+     for command, similar to the C language (*note Looping
+     Constructs::).
+
+   * Bash includes the 'select' compound command, which allows the
+     generation of simple menus (*note Conditional Constructs::).
+
+   * Bash includes the '[[' compound command, which makes conditional
+     testing part of the shell grammar (*note Conditional Constructs::),
+     including optional regular expression matching.
+
+   * Bash provides optional case-insensitive matching for the 'case' and
+     '[[' constructs.
+
+   * Bash includes brace expansion (*note Brace Expansion::) and tilde
+     expansion (*note Tilde Expansion::).
+
+   * Bash implements command aliases and the 'alias' and 'unalias'
+     builtins (*note Aliases::).
+
+   * Bash provides shell arithmetic, the '((' compound command (*note
+     Conditional Constructs::), and arithmetic expansion (*note Shell
+     Arithmetic::).
+
+   * Variables present in the shell's initial environment are
+     automatically exported to child processes.  The Bourne shell does
+     not normally do this unless the variables are explicitly marked
+     using the 'export' command.
+
+   * Bash supports the '+=' assignment operator, which appends to the
+     value of the variable named on the left hand side.
+
+   * Bash includes the POSIX pattern removal '%', '#', '%%' and '##'
+     expansions to remove leading or trailing substrings from variable
+     values (*note Shell Parameter Expansion::).
+
+   * The expansion '${#xx}', which returns the length of '${xx}', is
+     supported (*note Shell Parameter Expansion::).
+
+   * The expansion '${var:'OFFSET'[:'LENGTH']}', which expands to the
+     substring of 'var''s value of length LENGTH, beginning at OFFSET,
+     is present (*note Shell Parameter Expansion::).
+
+   * The expansion '${VAR/[/]'PATTERN'[/'REPLACEMENT']}', which matches
+     PATTERN and replaces it with REPLACEMENT in the value of VAR, is
+     available (*note Shell Parameter Expansion::).
+
+   * The expansion '${!PREFIX*}' expansion, which expands to the names
+     of all shell variables whose names begin with PREFIX, is available
+     (*note Shell Parameter Expansion::).
+
+   * Bash has indirect variable expansion using '${!word}' (*note Shell
+     Parameter Expansion::).
+
+   * Bash can expand positional parameters beyond '$9' using '${NUM}'.
+
+   * The POSIX '$()' form of command substitution is implemented (*note
+     Command Substitution::), and preferred to the Bourne shell's '``'
+     (which is also implemented for backwards compatibility).
+
+   * Bash has process substitution (*note Process Substitution::).
+
+   * Bash automatically assigns variables that provide information about
+     the current user ('UID', 'EUID', and 'GROUPS'), the current host
+     ('HOSTTYPE', 'OSTYPE', 'MACHTYPE', and 'HOSTNAME'), and the
+     instance of Bash that is running ('BASH', 'BASH_VERSION', and
+     'BASH_VERSINFO').  *Note Bash Variables::, for details.
+
+   * The 'IFS' variable is used to split only the results of expansion,
+     not all words (*note Word Splitting::).  This closes a longstanding
+     shell security hole.
+
+   * The filename expansion bracket expression code uses '!' and '^' to
+     negate the set of characters between the brackets.  The Bourne
+     shell uses only '!'.
+
+   * Bash implements the full set of POSIX filename expansion operators,
+     including character classes, equivalence classes, and collating
+     symbols (*note Filename Expansion::).
+
+   * Bash implements extended pattern matching features when the
+     'extglob' shell option is enabled (*note Pattern Matching::).
+
+   * It is possible to have a variable and a function with the same
+     name; 'sh' does not separate the two name spaces.
+
+   * Bash functions are permitted to have local variables using the
+     'local' builtin, and thus useful recursive functions may be written
+     (*note Bash Builtins::).
+
+   * Variable assignments preceding commands affect only that command,
+     even builtins and functions (*note Environment::).  In 'sh', all
+     variable assignments preceding commands are global unless the
+     command is executed from the file system.
+
+   * Bash performs filename expansion on filenames specified as operands
+     to input and output redirection operators (*note Redirections::).
+
+   * Bash contains the '<>' redirection operator, allowing a file to be
+     opened for both reading and writing, and the '&>' redirection
+     operator, for directing standard output and standard error to the
+     same file (*note Redirections::).
+
+   * Bash includes the '<<<' redirection operator, allowing a string to
+     be used as the standard input to a command.
+
+   * Bash implements the '[n]<&WORD' and '[n]>&WORD' redirection
+     operators, which move one file descriptor to another.
+
+   * Bash treats a number of filenames specially when they are used in
+     redirection operators (*note Redirections::).
+
+   * Bash can open network connections to arbitrary machines and
+     services with the redirection operators (*note Redirections::).
+
+   * The 'noclobber' option is available to avoid overwriting existing
+     files with output redirection (*note The Set Builtin::).  The '>|'
+     redirection operator may be used to override 'noclobber'.
+
+   * The Bash 'cd' and 'pwd' builtins (*note Bourne Shell Builtins::)
+     each take '-L' and '-P' options to switch between logical and
+     physical modes.
+
+   * Bash allows a function to override a builtin with the same name,
+     and provides access to that builtin's functionality within the
+     function via the 'builtin' and 'command' builtins (*note Bash
+     Builtins::).
+
+   * The 'command' builtin allows selective disabling of functions when
+     command lookup is performed (*note Bash Builtins::).
+
+   * Individual builtins may be enabled or disabled using the 'enable'
+     builtin (*note Bash Builtins::).
+
+   * The Bash 'exec' builtin takes additional options that allow users
+     to control the contents of the environment passed to the executed
+     command, and what the zeroth argument to the command is to be
+     (*note Bourne Shell Builtins::).
+
+   * Shell functions may be exported to children via the environment
+     using 'export -f' (*note Shell Functions::).
+
+   * The Bash 'export', 'readonly', and 'declare' builtins can take a
+     '-f' option to act on shell functions, a '-p' option to display
+     variables with various attributes set in a format that can be used
+     as shell input, a '-n' option to remove various variable
+     attributes, and 'name=value' arguments to set variable attributes
+     and values simultaneously.
+
+   * The Bash 'hash' builtin allows a name to be associated with an
+     arbitrary filename, even when that filename cannot be found by
+     searching the '$PATH', using 'hash -p' (*note Bourne Shell
+     Builtins::).
+
+   * Bash includes a 'help' builtin for quick reference to shell
+     facilities (*note Bash Builtins::).
+
+   * The 'printf' builtin is available to display formatted output
+     (*note Bash Builtins::).
+
+   * The Bash 'read' builtin (*note Bash Builtins::) will read a line
+     ending in '\' with the '-r' option, and will use the 'REPLY'
+     variable as a default if no non-option arguments are supplied.  The
+     Bash 'read' builtin also accepts a prompt string with the '-p'
+     option and will use Readline to obtain the line when given the '-e'
+     option.  The 'read' builtin also has additional options to control
+     input: the '-s' option will turn off echoing of input characters as
+     they are read, the '-t' option will allow 'read' to time out if
+     input does not arrive within a specified number of seconds, the
+     '-n' option will allow reading only a specified number of
+     characters rather than a full line, and the '-d' option will read
+     until a particular character rather than newline.
+
+   * The 'return' builtin may be used to abort execution of scripts
+     executed with the '.' or 'source' builtins (*note Bourne Shell
+     Builtins::).
+
+   * Bash includes the 'shopt' builtin, for finer control of shell
+     optional capabilities (*note The Shopt Builtin::), and allows these
+     options to be set and unset at shell invocation (*note Invoking
+     Bash::).
+
+   * Bash has much more optional behavior controllable with the 'set'
+     builtin (*note The Set Builtin::).
+
+   * The '-x' ('xtrace') option displays commands other than simple
+     commands when performing an execution trace (*note The Set
+     Builtin::).
+
+   * The 'test' builtin (*note Bourne Shell Builtins::) is slightly
+     different, as it implements the POSIX algorithm, which specifies
+     the behavior based on the number of arguments.
+
+   * Bash includes the 'caller' builtin, which displays the context of
+     any active subroutine call (a shell function or a script executed
+     with the '.' or 'source' builtins).  This supports the Bash
+     debugger.
+
+   * The 'trap' builtin (*note Bourne Shell Builtins::) allows a 'DEBUG'
+     pseudo-signal specification, similar to 'EXIT'.  Commands specified
+     with a 'DEBUG' trap are executed before every simple command, 'for'
+     command, 'case' command, 'select' command, every arithmetic 'for'
+     command, and before the first command executes in a shell function.
+     The 'DEBUG' trap is not inherited by shell functions unless the
+     function has been given the 'trace' attribute or the 'functrace'
+     option has been enabled using the 'shopt' builtin.  The 'extdebug'
+     shell option has additional effects on the 'DEBUG' trap.
+
+     The 'trap' builtin (*note Bourne Shell Builtins::) allows an 'ERR'
+     pseudo-signal specification, similar to 'EXIT' and 'DEBUG'.
+     Commands specified with an 'ERR' trap are executed after a simple
+     command fails, with a few exceptions.  The 'ERR' trap is not
+     inherited by shell functions unless the '-o errtrace' option to the
+     'set' builtin is enabled.
+
+     The 'trap' builtin (*note Bourne Shell Builtins::) allows a
+     'RETURN' pseudo-signal specification, similar to 'EXIT' and
+     'DEBUG'.  Commands specified with a 'RETURN' trap are executed
+     before execution resumes after a shell function or a shell script
+     executed with '.' or 'source' returns.  The 'RETURN' trap is not
+     inherited by shell functions unless the function has been given the
+     'trace' attribute or the 'functrace' option has been enabled using
+     the 'shopt' builtin.
+
+   * The Bash 'type' builtin is more extensive and gives more
+     information about the names it finds (*note Bash Builtins::).
+
+   * The Bash 'umask' builtin permits a '-p' option to cause the output
+     to be displayed in the form of a 'umask' command that may be reused
+     as input (*note Bourne Shell Builtins::).
+
+   * Bash implements a 'csh'-like directory stack, and provides the
+     'pushd', 'popd', and 'dirs' builtins to manipulate it (*note The
+     Directory Stack::).  Bash also makes the directory stack visible as
+     the value of the 'DIRSTACK' shell variable.
+
+   * Bash interprets special backslash-escaped characters in the prompt
+     strings when interactive (*note Controlling the Prompt::).
+
+   * The Bash restricted mode is more useful (*note The Restricted
+     Shell::); the SVR4.2 shell restricted mode is too limited.
+
+   * The 'disown' builtin can remove a job from the internal shell job
+     table (*note Job Control Builtins::) or suppress the sending of
+     'SIGHUP' to a job when the shell exits as the result of a 'SIGHUP'.
+
+   * Bash includes a number of features to support a separate debugger
+     for shell scripts.
+
+   * The SVR4.2 shell has two privilege-related builtins ('mldmode' and
+     'priv') not present in Bash.
+
+   * Bash does not have the 'stop' or 'newgrp' builtins.
+
+   * Bash does not use the 'SHACCT' variable or perform shell
+     accounting.
+
+   * The SVR4.2 'sh' uses a 'TIMEOUT' variable like Bash uses 'TMOUT'.
+
+More features unique to Bash may be found in *note Bash Features::.
+
+B.1 Implementation Differences From The SVR4.2 Shell
+====================================================
+
+Since Bash is a completely new implementation, it does not suffer from
+many of the limitations of the SVR4.2 shell.  For instance:
+
+   * Bash does not fork a subshell when redirecting into or out of a
+     shell control structure such as an 'if' or 'while' statement.
+
+   * Bash does not allow unbalanced quotes.  The SVR4.2 shell will
+     silently insert a needed closing quote at 'EOF' under certain
+     circumstances.  This can be the cause of some hard-to-find errors.
+
+   * The SVR4.2 shell uses a baroque memory management scheme based on
+     trapping 'SIGSEGV'.  If the shell is started from a process with
+     'SIGSEGV' blocked (e.g., by using the 'system()' C library function
+     call), it misbehaves badly.
+
+   * In a questionable attempt at security, the SVR4.2 shell, when
+     invoked without the '-p' option, will alter its real and effective
+     UID and GID if they are less than some magic threshold value,
+     commonly 100.  This can lead to unexpected results.
+
+   * The SVR4.2 shell does not allow users to trap 'SIGSEGV', 'SIGALRM',
+     or 'SIGCHLD'.
+
+   * The SVR4.2 shell does not allow the 'IFS', 'MAILCHECK', 'PATH',
+     'PS1', or 'PS2' variables to be unset.
+
+   * The SVR4.2 shell treats '^' as the undocumented equivalent of '|'.
+
+   * Bash allows multiple option arguments when it is invoked ('-x -v');
+     the SVR4.2 shell allows only one option argument ('-xv').  In fact,
+     some versions of the shell dump core if the second argument begins
+     with a '-'.
+
+   * The SVR4.2 shell exits a script if any builtin fails; Bash exits a
+     script only if one of the POSIX special builtins fails, and only
+     for certain failures, as enumerated in the POSIX standard.
+
+   * The SVR4.2 shell behaves differently when invoked as 'jsh' (it
+     turns on job control).

+
+     Everyone is permitted to copy and distribute verbatim copies
+     of this license document, but changing it is not allowed.
+
+  0. PREAMBLE
+
+     The purpose of this License is to make a manual, textbook, or other
+     functional and useful document "free" in the sense of freedom: to
+     assure everyone the effective freedom to copy and redistribute it,
+     with or without modifying it, either commercially or
+     noncommercially.  Secondarily, this License preserves for the
+     author and publisher a way to get credit for their work, while not
+     being considered responsible for modifications made by others.
+
+     This License is a kind of "copyleft", which means that derivative
+     works of the document must themselves be free in the same sense.
+     It complements the GNU General Public License, which is a copyleft
+     license designed for free software.
+
+     We have designed this License in order to use it for manuals for
+     free software, because free software needs free documentation: a
+     free program should come with manuals providing the same freedoms
+     that the software does.  But this License is not limited to
+     software manuals; it can be used for any textual work, regardless
+     of subject matter or whether it is published as a printed book.  We
+     recommend this License principally for works whose purpose is
+     instruction or reference.
+
+  1. APPLICABILITY AND DEFINITIONS
+
+     This License applies to any manual or other work, in any medium,
+     that contains a notice placed by the copyright holder saying it can
+     be distributed under the terms of this License.  Such a notice
+     grants a world-wide, royalty-free license, unlimited in duration,
+     to use that work under the conditions stated herein.  The
+     "Document", below, refers to any such manual or work.  Any member
+     of the public is a licensee, and is addressed as "you".  You accept
+     the license if you copy, modify or distribute the work in a way
+     requiring permission under copyright law.
+
+     A "Modified Version" of the Document means any work containing the
+     Document or a portion of it, either copied verbatim, or with
+     modifications and/or translated into another language.
+
+     A "Secondary Section" is a named appendix or a front-matter section
+     of the Document that deals exclusively with the relationship of the
+     publishers or authors of the Document to the Document's overall
+     subject (or to related matters) and contains nothing that could
+     fall directly within that overall subject.  (Thus, if the Document
+     is in part a textbook of mathematics, a Secondary Section may not
+     explain any mathematics.)  The relationship could be a matter of
+     historical connection with the subject or with related matters, or
+     of legal, commercial, philosophical, ethical or political position
+     regarding them.
+
+     The "Invariant Sections" are certain Secondary Sections whose
+     titles are designated, as being those of Invariant Sections, in the
+     notice that says that the Document is released under this License.
+     If a section does not fit the above definition of Secondary then it
+     is not allowed to be designated as Invariant.  The Document may
+     contain zero Invariant Sections.  If the Document does not identify
+     any Invariant Sections then there are none.
+
+     The "Cover Texts" are certain short passages of text that are
+     listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+     that says that the Document is released under this License.  A
+     Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+     be at most 25 words.
+
+     A "Transparent" copy of the Document means a machine-readable copy,
+     represented in a format whose specification is available to the
+     general public, that is suitable for revising the document
+     straightforwardly with generic text editors or (for images composed
+     of pixels) generic paint programs or (for drawings) some widely
+     available drawing editor, and that is suitable for input to text
+     formatters or for automatic translation to a variety of formats
+     suitable for input to text formatters.  A copy made in an otherwise
+     Transparent file format whose markup, or absence of markup, has
+     been arranged to thwart or discourage subsequent modification by
+     readers is not Transparent.  An image format is not Transparent if
+     used for any substantial amount of text.  A copy that is not
+     "Transparent" is called "Opaque".
+
+     Examples of suitable formats for Transparent copies include plain
+     ASCII without markup, Texinfo input format, LaTeX input format,
+     SGML or XML using a publicly available DTD, and standard-conforming
+     simple HTML, PostScript or PDF designed for human modification.
+     Examples of transparent image formats include PNG, XCF and JPG.
+     Opaque formats include proprietary formats that can be read and
+     edited only by proprietary word processors, SGML or XML for which
+     the DTD and/or processing tools are not generally available, and
+     the machine-generated HTML, PostScript or PDF produced by some word
+     processors for output purposes only.
+
+     The "Title Page" means, for a printed book, the title page itself,
+     plus such following pages as are needed to hold, legibly, the
+     material this License requires to appear in the title page.  For
+     works in formats which do not have any title page as such, "Title
+     Page" means the text near the most prominent appearance of the
+     work's title, preceding the beginning of the body of the text.
+
+     The "publisher" means any person or entity that distributes copies
+     of the Document to the public.
+
+     A section "Entitled XYZ" means a named subunit of the Document
+     whose title either is precisely XYZ or contains XYZ in parentheses
+     following text that translates XYZ in another language.  (Here XYZ
+     stands for a specific section name mentioned below, such as
+     "Acknowledgements", "Dedications", "Endorsements", or "History".)
+     To "Preserve the Title" of such a section when you modify the
+     Document means that it remains a section "Entitled XYZ" according
+     to this definition.
+
+     The Document may include Warranty Disclaimers next to the notice
+     which states that this License applies to the Document.  These
+     Warranty Disclaimers are considered to be included by reference in
+     this License, but only as regards disclaiming warranties: any other
+     implication that these Warranty Disclaimers may have is void and
+     has no effect on the meaning of this License.
+
+  2. VERBATIM COPYING
+
+     You may copy and distribute the Document in any medium, either
+     commercially or noncommercially, provided that this License, the
+     copyright notices, and the license notice saying this License
+     applies to the Document are reproduced in all copies, and that you
+     add no other conditions whatsoever to those of this License.  You
+     may not use technical measures to obstruct or control the reading
+     or further copying of the copies you make or distribute.  However,
+     you may accept compensation in exchange for copies.  If you
+     distribute a large enough number of copies you must also follow the
+     conditions in section 3.
+
+     You may also lend copies, under the same conditions stated above,
+     and you may publicly display copies.
+
+  3. COPYING IN QUANTITY
+
+     If you publish printed copies (or copies in media that commonly
+     have printed covers) of the Document, numbering more than 100, and
+     the Document's license notice requires Cover Texts, you must
+     enclose the copies in covers that carry, clearly and legibly, all
+     these Cover Texts: Front-Cover Texts on the front cover, and
+     Back-Cover Texts on the back cover.  Both covers must also clearly
+     and legibly identify you as the publisher of these copies.  The
+     front cover must present the full title with all words of the title
+     equally prominent and visible.  You may add other material on the
+     covers in addition.  Copying with changes limited to the covers, as
+     long as they preserve the title of the Document and satisfy these
+     conditions, can be treated as verbatim copying in other respects.
+
+     If the required texts for either cover are too voluminous to fit
+     legibly, you should put the first ones listed (as many as fit
+     reasonably) on the actual cover, and continue the rest onto
+     adjacent pages.
+
+     If you publish or distribute Opaque copies of the Document
+     numbering more than 100, you must either include a machine-readable
+     Transparent copy along with each Opaque copy, or state in or with
+     each Opaque copy a computer-network location from which the general
+     network-using public has access to download using public-standard
+     network protocols a complete Transparent copy of the Document, free
+     of added material.  If you use the latter option, you must take
+     reasonably prudent steps, when you begin distribution of Opaque
+     copies in quantity, to ensure that this Transparent copy will
+     remain thus accessible at the stated location until at least one
+     year after the last time you distribute an Opaque copy (directly or
+     through your agents or retailers) of that edition to the public.
+
+     It is requested, but not required, that you contact the authors of
+     the Document well before redistributing any large number of copies,
+     to give them a chance to provide you with an updated version of the
+     Document.
+
+  4. MODIFICATIONS
+
+     You may copy and distribute a Modified Version of the Document
+     under the conditions of sections 2 and 3 above, provided that you
+     release the Modified Version under precisely this License, with the
+     Modified Version filling the role of the Document, thus licensing
+     distribution and modification of the Modified Version to whoever
+     possesses a copy of it.  In addition, you must do these things in
+     the Modified Version:
+
+       A. Use in the Title Page (and on the covers, if any) a title
+          distinct from that of the Document, and from those of previous
+          versions (which should, if there were any, be listed in the
+          History section of the Document).  You may use the same title
+          as a previous version if the original publisher of that
+          version gives permission.
+
+       B. List on the Title Page, as authors, one or more persons or
+          entities responsible for authorship of the modifications in
+          the Modified Version, together with at least five of the
+          principal authors of the Document (all of its principal
+          authors, if it has fewer than five), unless they release you
+          from this requirement.
+
+       C. State on the Title page the name of the publisher of the
+          Modified Version, as the publisher.
+
+       D. Preserve all the copyright notices of the Document.
+
+       E. Add an appropriate copyright notice for your modifications
+          adjacent to the other copyright notices.
+
+       F. Include, immediately after the copyright notices, a license
+          notice giving the public permission to use the Modified
+          Version under the terms of this License, in the form shown in
+          the Addendum below.
+
+       G. Preserve in that license notice the full lists of Invariant
+          Sections and required Cover Texts given in the Document's
+          license notice.
+
+       H. Include an unaltered copy of this License.
+
+       I. Preserve the section Entitled "History", Preserve its Title,
+          and add to it an item stating at least the title, year, new
+          authors, and publisher of the Modified Version as given on the
+          Title Page.  If there is no section Entitled "History" in the
+          Document, create one stating the title, year, authors, and
+          publisher of the Document as given on its Title Page, then add
+          an item describing the Modified Version as stated in the
+          previous sentence.
+
+       J. Preserve the network location, if any, given in the Document
+          for public access to a Transparent copy of the Document, and
+          likewise the network locations given in the Document for
+          previous versions it was based on.  These may be placed in the
+          "History" section.  You may omit a network location for a work
+          that was published at least four years before the Document
+          itself, or if the original publisher of the version it refers
+          to gives permission.
+
+       K. For any section Entitled "Acknowledgements" or "Dedications",
+          Preserve the Title of the section, and preserve in the section
+          all the substance and tone of each of the contributor
+          acknowledgements and/or dedications given therein.
+
+       L. Preserve all the Invariant Sections of the Document, unaltered
+          in their text and in their titles.  Section numbers or the
+          equivalent are not considered part of the section titles.
+
+       M. Delete any section Entitled "Endorsements".  Such a section
+          may not be included in the Modified Version.
+
+       N. Do not retitle any existing section to be Entitled
+          "Endorsements" or to conflict in title with any Invariant
+          Section.
+
+       O. Preserve any Warranty Disclaimers.
+
+     If the Modified Version includes new front-matter sections or
+     appendices that qualify as Secondary Sections and contain no
+     material copied from the Document, you may at your option designate
+     some or all of these sections as invariant.  To do this, add their
+     titles to the list of Invariant Sections in the Modified Version's
+     license notice.  These titles must be distinct from any other
+     section titles.
+
+     You may add a section Entitled "Endorsements", provided it contains
+     nothing but endorsements of your Modified Version by various
+     parties--for example, statements of peer review or that the text
+     has been approved by an organization as the authoritative
+     definition of a standard.
+
+     You may add a passage of up to five words as a Front-Cover Text,
+     and a passage of up to 25 words as a Back-Cover Text, to the end of
+     the list of Cover Texts in the Modified Version.  Only one passage
+     of Front-Cover Text and one of Back-Cover Text may be added by (or
+     through arrangements made by) any one entity.  If the Document
+     already includes a cover text for the same cover, previously added
+     by you or by arrangement made by the same entity you are acting on
+     behalf of, you may not add another; but you may replace the old
+     one, on explicit permission from the previous publisher that added
+     the old one.
+
+     The author(s) and publisher(s) of the Document do not by this
+     License give permission to use their names for publicity for or to
+     assert or imply endorsement of any Modified Version.
+
+  5. COMBINING DOCUMENTS
+
+     You may combine the Document with other documents released under
+     this License, under the terms defined in section 4 above for
+     modified versions, provided that you include in the combination all
+     of the Invariant Sections of all of the original documents,
+     unmodified, and list them all as Invariant Sections of your
+     combined work in its license notice, and that you preserve all
+     their Warranty Disclaimers.
+
+     The combined work need only contain one copy of this License, and
+     multiple identical Invariant Sections may be replaced with a single
+     copy.  If there are multiple Invariant Sections with the same name
+     but different contents, make the title of each such section unique
+     by adding at the end of it, in parentheses, the name of the
+     original author or publisher of that section if known, or else a
+     unique number.  Make the same adjustment to the section titles in
+     the list of Invariant Sections in the license notice of the
+     combined work.
+
+     In the combination, you must combine any sections Entitled
+     "History" in the various original documents, forming one section
+     Entitled "History"; likewise combine any sections Entitled
+     "Acknowledgements", and any sections Entitled "Dedications".  You
+     must delete all sections Entitled "Endorsements."
+
+  6. COLLECTIONS OF DOCUMENTS
+
+     You may make a collection consisting of the Document and other
+     documents released under this License, and replace the individual
+     copies of this License in the various documents with a single copy
+     that is included in the collection, provided that you follow the
+     rules of this License for verbatim copying of each of the documents
+     in all other respects.
+
+     You may extract a single document from such a collection, and
+     distribute it individually under this License, provided you insert
+     a copy of this License into the extracted document, and follow this
+     License in all other respects regarding verbatim copying of that
+     document.
+
+  7. AGGREGATION WITH INDEPENDENT WORKS
+
+     A compilation of the Document or its derivatives with other
+     separate and independent documents or works, in or on a volume of a
+     storage or distribution medium, is called an "aggregate" if the
+     copyright resulting from the compilation is not used to limit the
+     legal rights of the compilation's users beyond what the individual
+     works permit.  When the Document is included in an aggregate, this
+     License does not apply to the other works in the aggregate which
+     are not themselves derivative works of the Document.
+
+     If the Cover Text requirement of section 3 is applicable to these
+     copies of the Document, then if the Document is less than one half
+     of the entire aggregate, the Document's Cover Texts may be placed
+     on covers that bracket the Document within the aggregate, or the
+     electronic equivalent of covers if the Document is in electronic
+     form.  Otherwise they must appear on printed covers that bracket
+     the whole aggregate.
+
+  8. TRANSLATION
+
+     Translation is considered a kind of modification, so you may
+     distribute translations of the Document under the terms of section
+     4.  Replacing Invariant Sections with translations requires special
+     permission from their copyright holders, but you may include
+     translations of some or all Invariant Sections in addition to the
+     original versions of these Invariant Sections.  You may include a
+     translation of this License, and all the license notices in the
+     Document, and any Warranty Disclaimers, provided that you also
+     include the original English version of this License and the
+     original versions of those notices and disclaimers.  In case of a
+     disagreement between the translation and the original version of
+     this License or a notice or disclaimer, the original version will
+     prevail.
+
+     If a section in the Document is Entitled "Acknowledgements",
+     "Dedications", or "History", the requirement (section 4) to
+     Preserve its Title (section 1) will typically require changing the
+     actual title.
+
+  9. TERMINATION
+
+     You may not copy, modify, sublicense, or distribute the Document
+     except as expressly provided under this License.  Any attempt
+     otherwise to copy, modify, sublicense, or distribute it is void,
+     and will automatically terminate your rights under this License.
+
+     However, if you cease all violation of this License, then your
+     license from a particular copyright holder is reinstated (a)
+     provisionally, unless and until the copyright holder explicitly and
+     finally terminates your license, and (b) permanently, if the
+     copyright holder fails to notify you of the violation by some
+     reasonable means prior to 60 days after the cessation.
+
+     Moreover, your license from a particular copyright holder is
+     reinstated permanently if the copyright holder notifies you of the
+     violation by some reasonable means, this is the first time you have
+     received notice of violation of this License (for any work) from
+     that copyright holder, and you cure the violation prior to 30 days
+     after your receipt of the notice.
+
+     Termination of your rights under this section does not terminate
+     the licenses of parties who have received copies or rights from you
+     under this License.  If your rights have been terminated and not
+     permanently reinstated, receipt of a copy of some or all of the
+     same material does not give you any rights to use it.
+
+  10. FUTURE REVISIONS OF THIS LICENSE
+
+     The Free Software Foundation may publish new, revised versions of
+     the GNU Free Documentation License from time to time.  Such new
+     versions will be similar in spirit to the present version, but may
+     differ in detail to address new problems or concerns.  See
+     <http://www.gnu.org/copyleft/>.
+
+     Each version of the License is given a distinguishing version
+     number.  If the Document specifies that a particular numbered
+     version of this License "or any later version" applies to it, you
+     have the option of following the terms and conditions either of
+     that specified version or of any later version that has been
+     published (not as a draft) by the Free Software Foundation.  If the
+     Document does not specify a version number of this License, you may
+     choose any version ever published (not as a draft) by the Free
+     Software Foundation.  If the Document specifies that a proxy can
+     decide which future versions of this License can be used, that
+     proxy's public statement of acceptance of a version permanently
+     authorizes you to choose that version for the Document.
+
+  11. RELICENSING
+
+     "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+     World Wide Web server that publishes copyrightable works and also
+     provides prominent facilities for anybody to edit those works.  A
+     public wiki that anybody can edit is an example of such a server.
+     A "Massive Multiauthor Collaboration" (or "MMC") contained in the
+     site means any set of copyrightable works thus published on the MMC
+     site.
+
+     "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+     license published by Creative Commons Corporation, a not-for-profit
+     corporation with a principal place of business in San Francisco,
+     California, as well as future copyleft versions of that license
+     published by that same organization.
+
+     "Incorporate" means to publish or republish a Document, in whole or
+     in part, as part of another Document.
+
+     An MMC is "eligible for relicensing" if it is licensed under this
+     License, and if all works that were first published under this
+     License somewhere other than this MMC, and subsequently
+     incorporated in whole or in part into the MMC, (1) had no cover
+     texts or invariant sections, and (2) were thus incorporated prior
+     to November 1, 2008.
+
+     The operator of an MMC Site may republish an MMC contained in the
+     site under CC-BY-SA on the same site at any time before August 1,
+     2009, provided the MMC is eligible for relicensing.
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+       Copyright (C)  YEAR  YOUR NAME.
+       Permission is granted to copy, distribute and/or modify this document
+       under the terms of the GNU Free Documentation License, Version 1.3
+       or any later version published by the Free Software Foundation;
+       with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+       Texts.  A copy of the license is included in the section entitled ``GNU
+       Free Documentation License''.
+
+   If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts."  line with this:
+
+         with the Invariant Sections being LIST THEIR TITLES, with
+         the Front-Cover Texts being LIST, and with the Back-Cover Texts
+         being LIST.
+
+   If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+   If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of free
+software license, such as the GNU General Public License, to permit
+their use in free software.

+       bbaasshhbbuugg is a shell script to help the user compose and mail bug reports
+       concerning bash in a standard format.  bbaasshhbbuugg invokes the editor spec-
+       ified by the environment variable EEDDIITTOORR on a temporary copy of the bug
+       report format outline. The user must fill in the appropriate fields and
+       exit  the  editor.   bbaasshhbbuugg  then  mails  the completed report to _b_u_g_-
+       _b_a_s_h_@_g_n_u_._o_r_g, or _e_m_a_i_l_-_a_d_d_r_e_s_s.  If the report cannot be mailed, it  is
+       saved in the file _d_e_a_d_._b_a_s_h_b_u_g in the invoking user's home directory.
+
+       The  bug report format outline consists of several sections.  The first
+       section provides information about the machine, operating  system,  the
+       bash  version,  and  the  compilation  environment.  The second section
+       should be filled in with a description of the bug.  The  third  section
+       should  be  a  description  of  how to reproduce the bug.  The optional
+       fourth section is for a proposed fix.  Fixes are encouraged.

+The Bash home page is <a href="http://www.gnu.org/software/bash/">http://www.gnu.org/software/bash/</a>.
+</p>
+<p>This is Edition 5.2, last updated 19 September 2022,
+of <cite>The GNU Bash Reference Manual</cite>,
+for <code>Bash</code>, Version 5.2.
+</p>
+<p>Bash contains features that appear in other popular shells, and some
+features that only appear in Bash.  Some of the shells that Bash has
+borrowed concepts from are the Bourne Shell (<samp>sh</samp>), the Korn Shell
+(<samp>ksh</samp>), and the C-shell (<samp>csh</samp> and its successor,
+<samp>tcsh</samp>).  The following menu breaks the features up into
+categories, noting which features were inspired by other shells and
+which are specific to Bash.
+</p>
+<p>This manual is meant as a brief introduction to features found in
+Bash.  The Bash manual page should be used as the definitive
+reference on shell behavior.

+
+<p>Bash is the shell, or command language interpreter,
+for the <small>GNU</small> operating system.
+The name is an acronym for the &lsquo;<samp>Bourne-Again SHell</samp>&rsquo;,
+a pun on Stephen Bourne, the author of the direct ancestor of
+the current Unix shell <code>sh</code>, 
+which appeared in the Seventh Edition Bell Labs Research version
+of Unix.
+</p>
+<p>Bash is largely compatible with <code>sh</code> and incorporates useful
+features from the Korn shell <code>ksh</code> and the C shell <code>csh</code>.
+It is intended to be a conformant implementation of the <small>IEEE</small>
+<small>POSIX</small> Shell and Tools portion of the <small>IEEE</small> <small>POSIX</small>
+specification (<small>IEEE</small> Standard 1003.1).
+It offers functional improvements over <code>sh</code> for both interactive and
+programming use.
+</p>
+<p>While the <small>GNU</small> operating system provides other shells, including
+a version of <code>csh</code>, Bash is the default shell.
+Like other <small>GNU</small> software, Bash is quite portable.  It currently runs
+on nearly every version of Unix and a few other operating systems -
+independently-supported ports exist for <small>MS-DOS</small>, <small>OS/2</small>,
+and Windows platforms.

+
+<p>At its base, a shell is simply a macro processor that executes
+commands.  The term macro processor means functionality where text
+and symbols are expanded to create larger expressions.
+</p>
+<p>A Unix shell is both a command interpreter and a programming
+language.  As a command interpreter, the shell provides the user
+interface to the rich set of <small>GNU</small> utilities.  The programming
+language features allow these utilities to be combined.
+Files containing commands can be created, and become
+commands themselves.  These new commands have the same status as
+system commands in directories such as <samp>/bin</samp>, allowing users
+or groups to establish custom environments to automate their common
+tasks.
+</p>
+<p>Shells may be used interactively or non-interactively.  In
+interactive mode, they accept input typed from the keyboard.
+When executing non-interactively, shells execute commands read
+from a file.
+</p>
+<p>A shell allows execution of <small>GNU</small> commands, both synchronously and
+asynchronously.
+The shell waits for synchronous commands to complete before accepting
+more input; asynchronous commands continue to execute in parallel
+with the shell while it reads and executes additional commands.
+The <em>redirection</em> constructs permit
+fine-grained control of the input and output of those commands.
+Moreover, the shell allows control over the contents of commands&rsquo;
+environments.
+</p>
+<p>Shells also provide a small set of built-in
+commands (<em>builtins</em>) implementing functionality impossible
+or inconvenient to obtain via separate utilities.
+For example, <code>cd</code>, <code>break</code>, <code>continue</code>, and
+<code>exec</code> cannot be implemented outside of the shell because
+they directly manipulate the shell itself.
+The <code>history</code>, <code>getopts</code>, <code>kill</code>, or <code>pwd</code>
+builtins, among others, could be implemented in separate utilities,
+but they are more convenient to use as builtin commands.
+All of the shell builtins are described in
+subsequent sections.
+</p>
+<p>While executing commands is essential, most of the power (and
+complexity) of shells is due to their embedded programming
+languages.  Like any high-level language, the shell provides
+variables, flow control constructs, quoting, and functions. 
+</p>
+<p>Shells offer features geared specifically for
+interactive use rather than to augment the programming language. 
+These interactive features include job control, command line
+editing, command history and aliases.  Each of these features is
+described in this manual.

+
+<p>Bash is an acronym for &lsquo;<samp>Bourne-Again SHell</samp>&rsquo;.
+The Bourne shell is
+the traditional Unix shell originally written by Stephen Bourne.
+All of the Bourne shell builtin commands are available in Bash,
+The rules for evaluation and quoting are taken from the <small>POSIX</small>
+specification for the &lsquo;standard&rsquo; Unix shell.
+</p>
+<p>This chapter briefly summarizes the shell&rsquo;s &lsquo;building blocks&rsquo;:
+commands, control structures, shell functions, shell <i>parameters</i>,
+shell expansions,
+<i>redirections</i>, which are a way to direct input and output from
+and to named files, and how the shell executes commands.

+
+<p>When the shell reads input, it proceeds through a
+sequence of operations.  If the input indicates the beginning of a
+comment, the shell ignores the comment symbol (&lsquo;<samp>#</samp>&rsquo;), and the rest
+of that line.
+</p>                                
+<p>Otherwise, roughly speaking,  the shell reads its input and
+divides the input into words and operators, employing the quoting rules
+to select which meanings to assign various words and characters.
+</p>
+<p>The shell then parses these tokens into commands and other constructs,
+removes the special meaning of certain words or characters, expands
+others, redirects input and output as needed, executes the specified
+command, waits for the command&rsquo;s exit status, and makes that exit status
+available for further inspection or processing.

+
+<p>The following is a brief description of the shell&rsquo;s operation when it
+reads and executes a command.  Basically, the shell does the
+following:
+</p>
+<ol>
+<li> Reads its input from a file (see <a href="#Shell-Scripts">Shell Scripts</a>), from a string
+supplied as an argument to the <samp>-c</samp> invocation option
+(see <a href="#Invoking-Bash">Invoking Bash</a>), or from the user&rsquo;s terminal.
+
+</li><li> Breaks the input into words and operators, obeying the quoting rules
+described in <a href="#Quoting">Quoting</a>.  These tokens are separated by
+<code>metacharacters</code>.  Alias expansion is performed by this step
+(see <a href="#Aliases">Aliases</a>).
+
+</li><li> Parses the tokens into simple and compound commands
+(see <a href="#Shell-Commands">Shell Commands</a>).
+
+</li><li> Performs the various shell expansions (see <a href="#Shell-Expansions">Shell Expansions</a>), breaking
+the expanded tokens into lists of filenames (see <a href="#Filename-Expansion">Filename Expansion</a>)
+and commands and arguments.
+
+</li><li> Performs any necessary redirections (see <a href="#Redirections">Redirections</a>) and removes
+the redirection operators and their operands from the argument list.
+
+</li><li> Executes the command (see <a href="#Executing-Commands">Executing Commands</a>).
+
+</li><li> Optionally waits for the command to complete and collects its exit
+status (see <a href="#Exit-Status">Exit Status</a>).

+<span id="Quoting-1"></span><h4 class="subsection">3.1.2 Quoting</h4>
+<span id="index-quoting"></span>
+
+<p>Quoting is used to remove the special meaning of certain
+characters or words to the shell.  Quoting can be used to
+disable special treatment for special characters, to prevent
+reserved words from being recognized as such, and to prevent
+parameter expansion.
+</p>
+<p>Each of the shell metacharacters (see <a href="#Definitions">Definitions</a>)
+has special meaning to the shell and must be quoted if it is to
+represent itself.
+When the command history expansion facilities are being used
+(see <a href="#History-Interaction">History Expansion</a>), the
+<em>history expansion</em> character, usually &lsquo;<samp>!</samp>&rsquo;, must be quoted
+to prevent history expansion.  See <a href="#Bash-History-Facilities">Bash History Facilities</a>, for
+more details concerning history expansion.
+</p>
+<p>There are three quoting mechanisms: the
+<em>escape character</em>, single quotes, and double quotes.

+The characters &lsquo;<samp>$</samp>&rsquo; and &lsquo;<samp>`</samp>&rsquo;
+retain their special meaning within double quotes (see <a href="#Shell-Expansions">Shell Expansions</a>).

+the following characters:
+&lsquo;<samp>$</samp>&rsquo;, &lsquo;<samp>`</samp>&rsquo;, &lsquo;<samp>&quot;</samp>&rsquo;, &lsquo;<samp>\</samp>&rsquo;, or <code>newline</code>.
+Within double quotes, backslashes that are followed by one of these
+characters are removed.  Backslashes preceding characters without a
+special meaning are left unmodified.
+A double quote may be quoted within double quotes by preceding it with
+a backslash.
+If enabled, history expansion will be performed unless an &lsquo;<samp>!</samp>&rsquo;
+appearing in double quotes is escaped using a backslash.
+The backslash preceding the &lsquo;<samp>!</samp>&rsquo; is not removed.

+<p>Prefixing a double-quoted string with a dollar sign (&lsquo;<samp>$</samp>&rsquo;), such
+as <tt>$&quot;hello, world&quot;</tt>,
+will cause the string to be translated according to the current locale.
+The <code>gettext</code> infrastructure performs the lookup and 
+translation, using the <code>LC_MESSAGES</code>, <code>TEXTDOMAINDIR</code>,
+and <code>TEXTDOMAIN</code> shell variables, as explained below.
+See the gettext documentation for additional details not covered here.
+If the current locale is <code>C</code> or <code>POSIX</code>,
+if there are no translations available,
+of if the string is not translated,
+the dollar sign is ignored.
+Since this is a form of double quoting, the string remains double-quoted
+by default, whether or not it is translated and replaced.
+If the <code>noexpand_translation</code> option is enabled

+translated strings are single-quoted instead of double-quoted.

+<p>The rest of this section is a brief overview of how you use gettext to
+create translations for strings in a shell script named <var>scriptname</var>.
+There are more details in the gettext documentation.

+<h4 class="node-heading">Creating Internationalized Scripts</h4>
+<span id="index-internationalized-scripts"></span>
+<span id="index-string-translations"></span>
+<p>Once you&rsquo;ve marked the strings in your script
+that you want to translate using $&quot;...&quot;,
+you create a gettext &quot;template&quot; file using the command
+</p>
+<div class="example">
+<pre class="example">bash --dump-po-strings <var>scriptname</var> &gt; <var>domain</var>.pot
+</pre></div>
+
+<p>The <var>domain</var> is your <em>message domain</em>.
+It&rsquo;s just an arbitrary string that&rsquo;s used to identify the files gettext
+needs, like a package or script name.
+It needs to be unique among all
+the message domains on systems where you install the translations, so
+gettext knows which translations correspond to your script.
+You&rsquo;ll use the template file to create translations for each target language.
+The template file conventionally has the suffix &lsquo;<samp>.pot</samp>&rsquo;.
+</p>
+<p>You copy this template file to a separate file for each target language
+you want to support (called &quot;PO&quot; files, which use the suffix &lsquo;<samp>.po</samp>&rsquo;).
+PO files use various naming conventions, but
+when you are working to translate a template file into a particular
+language, you first copy the template file to a file whose name is the
+language you want to target, with the &lsquo;<samp>.po</samp>&rsquo; suffix.
+For instance, the Spanish translations of your strings would be
+in a file named &lsquo;<samp>es.po</samp>&rsquo;, and to get started using a message
+domain named &quot;example,&quot; you would run
+</p>
+<div class="example">
+<pre class="example">cp example.pot es.po
+</pre></div>
+
+<p>Ultimately, PO files are often named <var>domain</var>.po and installed in
+directories that contain multiple translation files for a particular language.
+</p>
+<p>Whichever naming convention you choose, you will need to translate the
+strings in the PO files into the appropriate languages.
+This has to be done manually.
+</p>
+<p>When you have the translations and PO files complete, you&rsquo;ll use the
+gettext tools to produce what are called &quot;MO&quot; files, which are compiled
+versions of the PO files the gettext tools use to look up translations
+efficiently.
+MO files are also called &quot;message catalog&quot; files.
+You use the <code>msgfmt</code> program to do this.
+For instance, if you had a file with Spanish translations, you could run
+</p>
+<div class="example">
+<pre class="example">msgfmt -o es.mo es.po
+</pre></div>
+
+<p>to produce the corresponding MO file.
+</p>
+<p>Once you have the MO files, you decide where to install them and use the
+<code>TEXTDOMAINDIR</code> shell variable to tell the gettext tools where they are.
+Make sure to use the same message domain to name the MO files 
+as you did for the PO files when you install them.
+</p>
+<span id="index-LANG"></span>
+<span id="index-LC_005fMESSAGES"></span>
+<span id="index-TEXTDOMAIN"></span>
+<span id="index-TEXTDOMAINDIR"></span>
+<p>Your users will use the <code>LANG</code> or <code>LC_MESSAGES</code> shell variables to
+select the desired language.
+</p>
+<p>You set the <code>TEXTDOMAIN</code> variable to the script&rsquo;s message domain.
+As above, you use the message domain to name your translation files.
+</p>
+<p>You, or possibly your users, set the <code>TEXTDOMAINDIR</code> variable to the
+name of a directory where the message catalog files are stored.
+If you install the message files into the system&rsquo;s standard message catalog
+directory, you don&rsquo;t need to worry about this variable.
+</p>
+<p>The directory where the message catalog files are stored varies between
+systems.
+Some use the message catalog selected by the <code>LC_MESSAGES</code>
+shell variable.
+Others create the name of the message catalog from the value of the
+<code>TEXTDOMAIN</code> shell variable, possibly adding the &lsquo;<samp>.mo</samp>&rsquo; suffix.
+If you use the <code>TEXTDOMAIN</code> variable, you may need to set the
+<code>TEXTDOMAINDIR</code> variable to the location of the message catalog files,
+as above.
+It&rsquo;s common to use both variables in this fashion:
+<code>$TEXTDOMAINDIR</code>/<code>$LC_MESSAGES</code>/LC_MESSAGES/<code>$TEXTDOMAIN</code>.mo.
+</p>
+<p>If you used that last convention, and you wanted to store the message
+catalog files with Spanish (es) and Esperanto (eo) translations into a
+local directory you use for custom translation files, you could run
+</p>
+<div class="example">
+<pre class="example">TEXTDOMAIN=example
+TEXTDOMAINDIR=/usr/local/share/locale
+
+cp es.mo ${TEXTDOMAINDIR}/es/LC_MESSAGES/${TEXTDOMAIN}.mo
+cp eo.mo ${TEXTDOMAINDIR}/eo/LC_MESSAGES/${TEXTDOMAIN}.mo
+</pre></div>
+
+<p>When all of this is done, and the message catalog files containing the
+compiled translations are installed in the correct location,
+your users will be able to see translated strings
+in any of the supported languages by setting the <code>LANG</code> or
+<code>LC_MESSAGES</code> environment variables before running your script.

+<p>Reserved words are words that have special meaning to the shell.
+They are used to begin and end the shell&rsquo;s compound commands.
+</p>
+<p>The following words are recognized as reserved when unquoted and 
+the first word of a command (see below for exceptions):
+</p>
+<table>
+<tr><td width="10%"><code>if</code></td><td width="10%"><code>then</code></td><td width="10%"><code>elif</code></td><td width="10%"><code>else</code></td><td width="12%"><code>fi</code></td><td width="10%"><code>time</code></td></tr>

+<p>A simple command is the kind of command encountered most often.
+It&rsquo;s just a sequence of words separated by <code>blank</code>s, terminated
+by one of the shell&rsquo;s control operators (see <a href="#Definitions">Definitions</a>).  The
+first word generally specifies a command to be executed, with the
+rest of the words being that command&rsquo;s arguments.

+<p>The return status (see <a href="#Exit-Status">Exit Status</a>) of a simple command is
+its exit status as provided

+
+<p>A <code>pipeline</code> is a sequence of one or more commands separated by
+one of the control operators &lsquo;<samp>|</samp>&rsquo; or &lsquo;<samp>|&amp;</samp>&rsquo;.
+</p>
+<span id="index-time"></span>
+<span id="index-_0021"></span>
+<span id="index-command-timing"></span>
+<p>The format for a pipeline is
+</p><div class="example">
+<pre class="example">[time [-p]] [!] <var>command1</var> [ | or |&amp; <var>command2</var> ] &hellip;
+</pre></div>
+
+<p>The output of each command in the pipeline is connected via a pipe
+to the input of the next command.
+That is, each command reads the previous command&rsquo;s output.  This
+connection is performed before any redirections specified by
+<var>command1</var>.
+</p>
+<p>If &lsquo;<samp>|&amp;</samp>&rsquo; is used, <var>command1</var>&rsquo;s standard error, in addition to
+its standard output, is connected to
+<var>command2</var>&rsquo;s standard input through the pipe;
+it is shorthand for <code>2&gt;&amp;1 |</code>.
+This implicit redirection of the standard error to the standard output is
+performed after any redirections specified by <var>command1</var>.
+</p>
+<p>The reserved word <code>time</code> causes timing statistics
+to be printed for the pipeline once it finishes.
+The statistics currently consist of elapsed (wall-clock) time and
+user and system time consumed by the command&rsquo;s execution.
+The <samp>-p</samp> option changes the output format to that specified
+by <small>POSIX</small>.
+When the shell is in <small>POSIX</small> mode (see <a href="#Bash-POSIX-Mode">Bash POSIX Mode</a>),
+it does not recognize <code>time</code> as a reserved word if the next
+token begins with a &lsquo;<samp>-</samp>&rsquo;.
+The <code>TIMEFORMAT</code> variable may be set to a format string that
+specifies how the timing information should be displayed.
+See <a href="#Bash-Variables">Bash Variables</a>, for a description of the available formats.
+The use of <code>time</code> as a reserved word permits the timing of
+shell builtins, shell functions, and pipelines.  An external
+<code>time</code> command cannot time these easily.
+</p>
+<p>When the shell is in <small>POSIX</small> mode (see <a href="#Bash-POSIX-Mode">Bash POSIX Mode</a>), <code>time</code>
+may be followed by a newline.  In this case, the shell displays the
+total user and system time consumed by the shell and its children.
+The <code>TIMEFORMAT</code> variable may be used to specify the format of
+the time information.
+</p>
+<p>If the pipeline is not executed asynchronously (see <a href="#Lists">Lists of Commands</a>), the
+shell waits for all commands in the pipeline to complete.
+</p>
+<p>Each command in a multi-command pipeline,
+where pipes are created,
+is executed in its own <em>subshell</em>, which is a
+separate process (see <a href="#Command-Execution-Environment">Command Execution Environment</a>).
+If the <code>lastpipe</code> option is enabled using the <code>shopt</code> builtin
+(see <a href="#The-Shopt-Builtin">The Shopt Builtin</a>),
+the last element of a pipeline may be run by the shell process
+when job control is not active.
+</p>
+<p>The exit
+status of a pipeline is the exit status of the last command in the
+pipeline, unless the <code>pipefail</code> option is enabled
+(see <a href="#The-Set-Builtin">The Set Builtin</a>).
+If <code>pipefail</code> is enabled, the pipeline&rsquo;s return status is the
+value of the last (rightmost) command to exit with a non-zero status,
+or zero if all commands exit successfully.
+If the reserved word &lsquo;<samp>!</samp>&rsquo; precedes the pipeline, the
+exit status is the logical negation of the exit status as described
+above.
+The shell waits for all commands in the pipeline to terminate before
+returning a value.

+<p>A <code>list</code> is a sequence of one or more pipelines separated by one
+of the operators &lsquo;<samp>;</samp>&rsquo;, &lsquo;<samp>&amp;</samp>&rsquo;, &lsquo;<samp>&amp;&amp;</samp>&rsquo;, or &lsquo;<samp>||</samp>&rsquo;,

+</p>
+<p>Of these list operators, &lsquo;<samp>&amp;&amp;</samp>&rsquo; and &lsquo;<samp>||</samp>&rsquo;
+have equal precedence, followed by &lsquo;<samp>;</samp>&rsquo; and &lsquo;<samp>&amp;</samp>&rsquo;,
+which have equal precedence.
+</p>
+<p>A sequence of one or more newlines may appear in a <code>list</code>
+to delimit commands, equivalent to a semicolon.
+</p>
+<p>If a command is terminated by the control operator &lsquo;<samp>&amp;</samp>&rsquo;,
+the shell executes the command asynchronously in a subshell.
+This is known as executing the command in the <em>background</em>,
+and these are referred to as <em>asynchronous</em> commands.
+The shell does not wait for the command to finish, and the return
+status is 0 (true).
+When job control is not active (see <a href="#Job-Control">Job Control</a>),
+the standard input for asynchronous commands, in the absence of any
+explicit redirections, is redirected from <code>/dev/null</code>.
+</p>
+<p>Commands separated by a &lsquo;<samp>;</samp>&rsquo; are executed sequentially; the shell
+waits for each command to terminate in turn.  The return status is the
+exit status of the last command executed.
+</p>
+<p><small>AND</small> and <small>OR</small> lists are sequences of one or more pipelines
+separated by the control operators &lsquo;<samp>&amp;&amp;</samp>&rsquo; and &lsquo;<samp>||</samp>&rsquo;,

+<p>The syntax of the <code>case</code> command is:

+<div class="example">
+<pre class="example">case <var>word</var> in
+    [ [(] <var>pattern</var> [| <var>pattern</var>]&hellip;) <var>command-list</var> ;;]&hellip;
+esac
+</pre></div>
+
+<p><code>case</code> will selectively execute the <var>command-list</var> corresponding to
+the first <var>pattern</var> that matches <var>word</var>.
+The match is performed according
+to the rules described below in <a href="#Pattern-Matching">Pattern Matching</a>.
+If the <code>nocasematch</code> shell option
+(see the description of <code>shopt</code> in <a href="#The-Shopt-Builtin">The Shopt Builtin</a>)
+is enabled, the match is performed without regard to the case
+of alphabetic characters.
+The &lsquo;<samp>|</samp>&rsquo; is used to separate multiple patterns, and the &lsquo;<samp>)</samp>&rsquo;
+operator terminates a pattern list.
+A list of patterns and an associated command-list is known
+as a <var>clause</var>.
+</p>
+<p>Each clause must be terminated with &lsquo;<samp>;;</samp>&rsquo;, &lsquo;<samp>;&amp;</samp>&rsquo;, or &lsquo;<samp>;;&amp;</samp>&rsquo;.
+The <var>word</var> undergoes tilde expansion, parameter expansion, command
+substitution, arithmetic expansion, and quote removal
+(see <a href="#Shell-Parameter-Expansion">Shell Parameter Expansion</a>)
+before matching is attempted.
+Each <var>pattern</var> undergoes tilde expansion, parameter expansion,
+command substitution, arithmetic expansion, process substitution, and
+quote removal.
+</p>
+<p>There may be an arbitrary number of <code>case</code> clauses, each terminated
+by a &lsquo;<samp>;;</samp>&rsquo;, &lsquo;<samp>;&amp;</samp>&rsquo;, or &lsquo;<samp>;;&amp;</samp>&rsquo;.
+The first pattern that matches determines the
+command-list that is executed.
+It&rsquo;s a common idiom to use &lsquo;<samp>*</samp>&rsquo; as the final pattern to define the
+default case, since that pattern will always match.
+</p>
+<p>Here is an example using <code>case</code> in a script that could be used to
+describe one interesting feature of an animal:
+</p>
+<div class="example">
+<pre class="example">echo -n &quot;Enter the name of an animal: &quot;
+read ANIMAL
+echo -n &quot;The $ANIMAL has &quot;
+case $ANIMAL in
+  horse | dog | cat) echo -n &quot;four&quot;;;
+  man | kangaroo ) echo -n &quot;two&quot;;;
+  *) echo -n &quot;an unknown number of&quot;;;
+esac
+echo &quot; legs.&quot;
+</pre></div>
+
+
+<p>If the &lsquo;<samp>;;</samp>&rsquo; operator is used, no subsequent matches are attempted after
+the first pattern match.
+Using &lsquo;<samp>;&amp;</samp>&rsquo;  in place of &lsquo;<samp>;;</samp>&rsquo; causes execution to continue with
+the <var>command-list</var> associated with the next clause, if any.
+Using &lsquo;<samp>;;&amp;</samp>&rsquo; in place of &lsquo;<samp>;;</samp>&rsquo; causes the shell to test the patterns
+in the next clause, if any, and execute any associated <var>command-list</var>
+on a successful match,
+continuing the case statement execution as if the pattern list had not matched.
+</p>
+<p>The return status is zero if no <var>pattern</var> is matched.  Otherwise, the
+return status is the exit status of the <var>command-list</var> executed.

+<dd>
+<p>The <code>select</code> construct allows the easy generation of menus.
+It has almost the same syntax as the <code>for</code> command:
+</p>
+<div class="example">
+<pre class="example">select <var>name</var> [in <var>words</var> &hellip;]; do <var>commands</var>; done
+</pre></div>
+
+<p>The list of words following <code>in</code> is expanded, generating a list
+of items, and the set of expanded words is printed on the standard
+error output stream, each preceded by a number.  If the
+&lsquo;<samp>in <var>words</var></samp>&rsquo; is omitted, the positional parameters are printed,
+as if &lsquo;<samp>in &quot;$@&quot;</samp>&rsquo; had been specified.
+<code>select</code> then displays the <code>PS3</code>
+prompt and reads a line from the standard input.
+If the line consists of a number corresponding to one of the displayed
+words, then the value of <var>name</var> is set to that word.
+If the line is empty, the words and prompt are displayed again.
+If <code>EOF</code> is read, the <code>select</code> command completes and returns 1.
+Any other value read causes <var>name</var> to be set to null.
+The line read is saved in the variable <code>REPLY</code>.
+</p>
+<p>The <var>commands</var> are executed after each selection until a
+<code>break</code> command is executed, at which
+point the <code>select</code> command completes.
+</p>
+<p>Here is an example that allows the user to pick a filename from the
+current directory, and displays the name and index of the file
+selected.
+</p>
+<div class="example">
+<pre class="example">select fname in *;
+do
+	echo you picked $fname \($REPLY\)

+<p>Return a status of 0 or 1 depending on the evaluation of
+the conditional expression <var>expression</var>.
+Expressions are composed of the primaries described below in
+<a href="#Bash-Conditional-Expressions">Bash Conditional Expressions</a>.
+The words between the <code>[[</code> and <code>]]</code> do not undergo word splitting
+and filename expansion.
+The shell performs tilde expansion, parameter and
+variable expansion, arithmetic expansion, command substitution, process
+substitution, and quote removal on those words
+(the expansions that would occur if the words were enclosed in double quotes).
+Conditional operators such as &lsquo;<samp>-f</samp>&rsquo; must be unquoted to be recognized
+as primaries.
+</p>
+<p>When used with <code>[[</code>, the &lsquo;<samp>&lt;</samp>&rsquo; and &lsquo;<samp>&gt;</samp>&rsquo; operators sort
+lexicographically using the current locale.
+</p>
+<p>When the &lsquo;<samp>==</samp>&rsquo; and &lsquo;<samp>!=</samp>&rsquo; operators are used, the string to the
+right of the operator is considered a pattern and matched according
+to the rules described below in <a href="#Pattern-Matching">Pattern Matching</a>,
+as if the <code>extglob</code> shell option were enabled.
+The &lsquo;<samp>=</samp>&rsquo; operator is identical to &lsquo;<samp>==</samp>&rsquo;.
+If the <code>nocasematch</code> shell option
+(see the description of <code>shopt</code> in <a href="#The-Shopt-Builtin">The Shopt Builtin</a>)
+is enabled, the match is performed without regard to the case
+of alphabetic characters.
+The return value is 0 if the string matches (&lsquo;<samp>==</samp>&rsquo;) or does not
+match (&lsquo;<samp>!=</samp>&rsquo;) the pattern, and 1 otherwise.
+</p>
+<p>If you quote any part of the pattern,
+using any of the shell&rsquo;s quoting mechanisms,
+the quoted portion is matched literally.
+This means every character in the quoted portion matches itself,
+instead of having any special pattern matching meaning.
+</p>
+<p>An additional binary operator, &lsquo;<samp>=~</samp>&rsquo;, is available, with the same
+precedence as &lsquo;<samp>==</samp>&rsquo; and &lsquo;<samp>!=</samp>&rsquo;.
+When you use &lsquo;<samp>=~</samp>&rsquo;, the string to the right of the operator is considered
+a <small>POSIX</small> extended regular expression pattern and matched accordingly
+(using the <small>POSIX</small> <code>regcomp</code> and <code>regexec</code> interfaces
+usually described in <i>regex</i>(3)).
+The return value is 0 if the string matches the pattern, and 1 if it does not.
+If the regular expression is syntactically incorrect, the conditional
+expression returns 2.
+If the <code>nocasematch</code> shell option
+(see the description of <code>shopt</code> in <a href="#The-Shopt-Builtin">The Shopt Builtin</a>)
+is enabled, the match is performed without regard to the case
+of alphabetic characters.
+</p>
+<p>You can quote any part of the pattern
+to force the quoted portion to be matched literally
+instead of as a regular expression (see above).
+If the pattern is stored in a shell variable, quoting the variable
+expansion forces the entire pattern to be matched literally.
+</p>
+<p>The pattern will match if it matches any part of the string.
+If you want to force the pattern to match the entire string,
+anchor the pattern using the &lsquo;<samp>^</samp>&rsquo; and &lsquo;<samp>$</samp>&rsquo; regular expression
+operators.
+</p>
+<p>For example, the following will match a line
+(stored in the shell variable <code>line</code>)
+if there is a sequence of characters anywhere in the value consisting of
+any number, including zero, of 
+characters in the <code>space</code> character class,
+immediately followed by zero or one instances of &lsquo;<samp>a</samp>&rsquo;,
+then a &lsquo;<samp>b</samp>&rsquo;:
+</p>
+<div class="example">
+<pre class="example">[[ $line =~ [[:space:]]*(a)?b ]]
+</pre></div>
+
+<p>That means values for <code>line</code> like
+&lsquo;<samp>aab</samp>&rsquo;, &lsquo;<samp>  aaaaaab</samp>&rsquo;, &lsquo;<samp>xaby</samp>&rsquo;, and &lsquo;<samp> ab</samp>&rsquo;
+will all match,
+as will a line containing a &lsquo;<samp>b</samp>&rsquo; anywhere in its value.
+</p>
+<p>If you want to match a character that&rsquo;s special to the regular expression
+grammar (&lsquo;<samp>^$|[]()\.*+?</samp>&rsquo;), it has to be quoted to remove its special
+meaning.
+This means that in the pattern &lsquo;<samp>xxx.txt</samp>&rsquo;, the &lsquo;<samp>.</samp>&rsquo; matches any
+character in the string (its usual regular expression meaning), but in the
+pattern &lsquo;<samp>&quot;xxx.txt&quot;</samp>&rsquo;, it can only match a literal &lsquo;<samp>.</samp>&rsquo;.
+</p>
+<p>Likewise, if you want to include a character in your pattern that has a
+special meaning to the regular expression grammar, you must make sure it&rsquo;s
+not quoted.
+If you want to anchor a pattern at the beginning or end of the string,
+for instance, you cannot quote the &lsquo;<samp>^</samp>&rsquo; or &lsquo;<samp>$</samp>&rsquo;
+characters using any form of shell quoting.
+</p>
+<p>If you want to match &lsquo;<samp>initial string</samp>&rsquo; at the start of a line,
+the following will work:
+</p><div class="example">
+<pre class="example">[[ $line =~ ^&quot;initial string&quot; ]]
+</pre></div>
+<p>but this will not:
+</p><div class="example">
+<pre class="example">[[ $line =~ &quot;^initial string&quot; ]]
+</pre></div>
+<p>because in the second example the &lsquo;<samp>^</samp>&rsquo; is quoted and doesn&rsquo;t have its
+usual special meaning.
+</p>
+<p>It is sometimes difficult to specify a regular expression properly
+without using quotes, or to keep track of the quoting used by regular
+expressions while paying attention to
+shell quoting and the shell&rsquo;s quote removal.
+Storing the regular expression in a shell variable is often a useful
+way to avoid problems with quoting characters that are special to the
+shell.
+For example, the following is equivalent to the pattern used above:
+</p>
+<div class="example">
+<pre class="example">pattern='[[:space:]]*(a)?b'
+[[ $line =~ $pattern ]]
+</pre></div>
+
+<p>Shell programmers should take special care with backslashes, since
+backslashes are used by both the shell and regular expressions to remove
+the special meaning from the following character.
+This means that after the shell&rsquo;s word expansions complete
+(see <a href="#Shell-Expansions">Shell Expansions</a>),
+any backslashes remaining in parts of the pattern
+that were originally not quoted can remove the
+special meaning of pattern characters.
+If any part of the pattern is quoted, the shell does its best to ensure that
+the regular expression treats those remaining backslashes as literal,
+if they appeared in a quoted portion.
+</p>
+<p>The following two sets of commands are <em>not</em> equivalent:
+</p>
+<div class="example">
+<pre class="example">pattern='\.'
+
+[[ . =~ $pattern ]]
+[[ . =~ \. ]]
+
+[[ . =~ &quot;$pattern&quot; ]]
+[[ . =~ '\.' ]]
+</pre></div>
+
+<p>The first two matches will succeed, but the second two will not, because
+in the second two the backslash will be part of the pattern to be matched.
+In the first two examples, the pattern passed to the regular expression
+parser is &lsquo;<samp>\.</samp>&rsquo;. The backslash removes the special meaning from
+&lsquo;<samp>.</samp>&rsquo;, so the literal &lsquo;<samp>.</samp>&rsquo; matches.
+In the second two examples, the pattern passed to the regular expression
+parser has the backslash quoted (e.g., &lsquo;<samp>\\\.</samp>&rsquo;), which will not match
+the string, since it does not contain a backslash.
+If the string in the first examples were anything other than &lsquo;<samp>.</samp>&rsquo;, say
+&lsquo;<samp>a</samp>&rsquo;, the pattern would not match, because the quoted &lsquo;<samp>.</samp>&rsquo; in the
+pattern loses its special meaning of matching any single character.
+</p>
+<p>Bracket expressions in regular expressions can be sources of errors as well,
+since characters that are normally special in regular expressions
+lose their special meanings between brackets.
+However, you can use bracket expressions to match special pattern characters
+without quoting them, so they are sometimes useful for this purpose.
+</p>
+<p>Though it might seem like a strange way to write it, the following pattern
+will match a &lsquo;<samp>.</samp>&rsquo; in the string:
+</p>
+<div class="example">
+<pre class="example">[[ . =~ [.] ]]
+</pre></div>
+
+<p>The shell performs any word expansions before passing the pattern
+to the regular expression functions,
+so you can assume that the shell&rsquo;s quoting takes precedence.
+As noted above, the regular expression parser will interpret any
+unquoted backslashes remaining in the pattern after shell expansion
+according to its own rules.
+The intention is to avoid making shell programmers quote things twice
+as much as possible, so shell quoting should be sufficient to quote
+special pattern characters where that&rsquo;s necessary.
+</p>
+<p>The array variable <code>BASH_REMATCH</code> records which parts of the string
+matched the pattern.
+The element of <code>BASH_REMATCH</code> with index 0 contains the portion of
+the string matching the entire regular expression.
+Substrings matched by parenthesized subexpressions within the regular
+expression are saved in the remaining <code>BASH_REMATCH</code> indices.
+The element of <code>BASH_REMATCH</code> with index <var>n</var> is the portion of the
+string matching the <var>n</var>th parenthesized subexpression.
+</p>
+<p>Bash sets
+<code>BASH_REMATCH</code>
+in the global scope; declaring it as a local variable will lead to
+unexpected results.
+</p>
+<p>Expressions may be combined using the following operators, listed
+in decreasing order of precedence:
+</p>
+<dl compact="compact">
+<dt><span><code>( <var>expression</var> )</code></span></dt>
+<dd><p>Returns the value of <var>expression</var>.
+This may be used to override the normal precedence of operators.
+</p>
+</dd>
+<dt><span><code>! <var>expression</var></code></span></dt>
+<dd><p>True if <var>expression</var> is false.
+</p>
+</dd>
+<dt><span><code><var>expression1</var> &amp;&amp; <var>expression2</var></code></span></dt>
+<dd><p>True if both <var>expression1</var> and <var>expression2</var> are true.
+</p>
+</dd>
+<dt><span><code><var>expression1</var> || <var>expression2</var></code></span></dt>
+<dd><p>True if either <var>expression1</var> or <var>expression2</var> is true.
+</p></dd>
+</dl>
+
+<p>The <code>&amp;&amp;</code> and <code>||</code> operators do not evaluate <var>expression2</var> if the
+value of <var>expression1</var> is sufficient to determine the return
+value of the entire conditional expression.

+
+<p>Bash provides two ways to group a list of commands to be executed
+as a unit.  When commands are grouped, redirections may be applied
+to the entire command list.  For example, the output of all the
+commands in the list may be redirected to a single stream.
+</p>
+<dl compact="compact">

+<dd><div class="example">

+</pre></div>
+
+<p>Placing a list of commands between parentheses forces the shell to create
+a subshell (see <a href="#Command-Execution-Environment">Command Execution Environment</a>), and each
+of the commands in <var>list</var> is executed in that subshell environment.
+Since the <var>list</var> is executed in a subshell, variable assignments do not
+remain in effect after the subshell completes. 
+</p>

+<div class="example">
+<pre class="example">{ <var>list</var>; }

+
+<p>Placing a list of commands between curly braces causes the list to
+be executed in the current shell context.  No subshell is created.
+The semicolon (or newline) following <var>list</var> is required.
+</p></dd>
+</dl>
+
+<p>In addition to the creation of a subshell, there is a subtle difference
+between these two constructs due to historical reasons.  The braces
+are reserved words, so they must be separated from the <var>list</var>
+by <code>blank</code>s or other shell metacharacters.
+The parentheses are operators, and are
+recognized as separate tokens by the shell even if they are not separated
+from the <var>list</var> by whitespace.

+<span id="index-coprocess"></span>
+
+<p>A <code>coprocess</code> is a shell command preceded by the <code>coproc</code>
+reserved word.
+A coprocess is executed asynchronously in a subshell, as if the command
+had been terminated with the &lsquo;<samp>&amp;</samp>&rsquo; control operator, with a two-way pipe
+established between the executing shell and the coprocess.
+</p>
+<p>The syntax for a coprocess is:
+</p>
+<div class="example">
+<pre class="example">coproc [<var>NAME</var>] <var>command</var> [<var>redirections</var>]
+</pre></div>
+
+<p>This creates a coprocess named <var>NAME</var>.
+<var>command</var> may be either a simple command (see <a href="#Simple-Commands">Simple Commands</a>)
+or a compound command (see <a href="#Compound-Commands">Compound Commands</a>).
+<var>NAME</var> is a shell variable name.
+If <var>NAME</var> is not supplied, the default name is <code>COPROC</code>.
+</p>
+<p>The recommended form to use for a coprocess is
+</p>
+<div class="example">
+<pre class="example">coproc <var>NAME</var> { <var>command</var>; }
+</pre></div>
+
+<p>This form is recommended because simple commands result in the coprocess
+always being named <code>COPROC</code>, and it is simpler to use and more complete
+than the other compound commands.
+</p>
+<p>There are other forms of coprocesses:
+</p>
+<div class="example">
+<pre class="example">coproc <var>NAME</var> <var>compound-command</var>
+coproc <var>compound-command</var>
+coproc <var>simple-command</var>
+</pre></div>
+
+<p>If <var>command</var> is a compound command, <var>NAME</var> is optional. The
+word following <code>coproc</code> determines whether that word is interpreted
+as a variable name: it is interpreted as <var>NAME</var> if it is not a
+reserved word that introduces a compound command.
+If <var>command</var> is a simple command, <var>NAME</var> is not allowed; this
+is to avoid confusion between <var>NAME</var> and the first word of the simple
+command.
+</p>
+<p>When the coprocess is executed, the shell creates an array variable
+(see <a href="#Arrays">Arrays</a>)
+named <var>NAME</var> in the context of the executing shell.
+The standard output of <var>command</var>
+is connected via a pipe to a file descriptor in the executing shell,
+and that file descriptor is assigned to <var>NAME</var>[0].
+The standard input of <var>command</var>
+is connected via a pipe to a file descriptor in the executing shell,
+and that file descriptor is assigned to <var>NAME</var>[1].
+This pipe is established before any redirections specified by the
+command (see <a href="#Redirections">Redirections</a>).
+The file descriptors can be utilized as arguments to shell commands
+and redirections using standard word expansions.
+Other than those created to execute command and process substitutions,
+the file descriptors are not available in subshells.
+</p>
+<p>The process ID of the shell spawned to execute the coprocess is
+available as the value of the variable <code><var>NAME</var>_PID</code>.
+The <code>wait</code>
+builtin command may be used to wait for the coprocess to terminate.
+</p>
+<p>Since the coprocess is created as an asynchronous command,
+the <code>coproc</code> command always returns success.
+The return status of a coprocess is the exit status of <var>command</var>.

+<p>There are ways to run commands in parallel that are not built into Bash.
+GNU Parallel is a tool to do just that.
+</p>
+<p>GNU Parallel, as its name suggests, can be used to build and run commands
+in parallel.  You may run the same command with different arguments, whether
+they are filenames, usernames, hostnames, or lines read from files.  GNU
+Parallel provides shorthand references to many of the most common operations
+(input lines, various portions of the input line, different ways to specify
+the input source, and so on).  Parallel can replace <code>xargs</code> or feed
+commands from its input sources to several different instances of Bash.
+</p>
+<p>For a complete description, refer to the GNU Parallel documentation, which
+is available at
+<a href="https://www.gnu.org/software/parallel/parallel_tutorial.html">https://www.gnu.org/software/parallel/parallel_tutorial.html</a>.

+<span id="Shell-Functions-1"></span><h3 class="section">3.3 Shell Functions</h3>
+<span id="index-shell-function"></span>
+<span id="index-functions_002c-shell"></span>
+
+<p>Shell functions are a way to group commands for later execution
+using a single name for the group.  They are executed just like
+a &quot;regular&quot; command.
+When the name of a shell function is used as a simple command name,
+the list of commands associated with that function name is executed.
+Shell functions are executed in the current
+shell context; no new process is created to interpret them.
+</p>
+<p>Functions are declared using this syntax:
+<span id="index-function"></span>
+</p><div class="example">
+<pre class="example"><var>fname</var> () <var>compound-command</var> [ <var>redirections</var> ]
+</pre></div>
+
+<p>or
+</p>
+<div class="example">
+<pre class="example">function <var>fname</var> [()] <var>compound-command</var> [ <var>redirections</var> ]
+</pre></div>
+
+<p>This defines a shell function named <var>fname</var>.  The reserved
+word <code>function</code> is optional.
+If the <code>function</code> reserved
+word is supplied, the parentheses are optional.
+The <em>body</em> of the function is the compound command
+<var>compound-command</var> (see <a href="#Compound-Commands">Compound Commands</a>).
+That command is usually a <var>list</var> enclosed between { and }, but
+may be any compound command listed above.
+If the <code>function</code> reserved word is used, but the
+parentheses are not supplied, the braces are recommended.
+<var>compound-command</var> is executed whenever <var>fname</var> is specified as the
+name of a simple command.
+When the shell is in <small>POSIX</small> mode (see <a href="#Bash-POSIX-Mode">Bash POSIX Mode</a>),
+<var>fname</var> must be a valid shell name and
+may not be the same as one of the special builtins
+(see <a href="#Special-Builtins">Special Builtins</a>).
+In default mode, a function name can be any unquoted shell word that does
+not contain &lsquo;<samp>$</samp>&rsquo;.
+Any redirections (see <a href="#Redirections">Redirections</a>) associated with the shell function
+are performed when the function is executed.
+A function definition may be deleted using the <samp>-f</samp> option to the
+<code>unset</code> builtin (see <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>).
+</p>
+<p>The exit status of a function definition is zero unless a syntax error
+occurs or a readonly function with the same name already exists.
+When executed, the exit status of a function is the exit status of the
+last command executed in the body.
+</p>
+<p>Note that for historical reasons, in the most common usage the curly braces
+that surround the body of the function must be separated from the body by
+<code>blank</code>s or newlines.
+This is because the braces are reserved words and are only recognized
+as such when they are separated from the command list
+by whitespace or another shell metacharacter.
+Also, when using the braces, the <var>list</var> must be terminated by a semicolon,
+a &lsquo;<samp>&amp;</samp>&rsquo;, or a newline.
+</p>
+<p>When a function is executed, the arguments to the
+function become the positional parameters
+during its execution (see <a href="#Positional-Parameters">Positional Parameters</a>).
+The special parameter &lsquo;<samp>#</samp>&rsquo; that expands to the number of
+positional parameters is updated to reflect the change.
+Special parameter <code>0</code> is unchanged.
+The first element of the <code>FUNCNAME</code> variable is set to the
+name of the function while the function is executing.
+</p>
+<p>All other aspects of the shell execution
+environment are identical between a function and its caller
+with these exceptions:
+the <code>DEBUG</code> and <code>RETURN</code> traps
+are not inherited unless the function has been given the
+<code>trace</code> attribute using the <code>declare</code> builtin or
+the <code>-o functrace</code> option has been enabled with
+the <code>set</code> builtin,
+(in which case all functions inherit the <code>DEBUG</code> and <code>RETURN</code> traps),
+and the <code>ERR</code> trap is not inherited unless the <code>-o errtrace</code>
+shell option has been enabled.
+See <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>, for the description of the
+<code>trap</code> builtin.
+</p>
+<p>The <code>FUNCNEST</code> variable, if set to a numeric value greater
+than 0, defines a maximum function nesting level.  Function
+invocations that exceed the limit cause the entire command to
+abort.
+</p>
+<p>If the builtin command <code>return</code>
+is executed in a function, the function completes and
+execution resumes with the next command after the function
+call.
+Any command associated with the <code>RETURN</code> trap is executed
+before execution resumes.
+When a function completes, the values of the
+positional parameters and the special parameter &lsquo;<samp>#</samp>&rsquo;
+are restored to the values they had prior to the function&rsquo;s
+execution.  If a numeric argument is given to <code>return</code>,
+that is the function&rsquo;s return status; otherwise the function&rsquo;s
+return status is the exit status of the last command executed
+before the <code>return</code>.
+</p>
+<p>Variables local to the function may be declared with the
+<code>local</code> builtin (<em>local variables</em>).
+Ordinarily, variables and their values
+are shared between a function and its caller.
+These variables are visible only to
+the function and the commands it invokes.  This is particularly
+important when a shell function calls other functions.
+</p>
+<p>In the following description, the <em>current scope</em> is a currently-
+executing function.
+Previous scopes consist of that function&rsquo;s caller and so on,
+back to the &quot;global&quot; scope, where the shell is not executing
+any shell function.
+Consequently, a local variable at the current local scope is a variable
+declared using the <code>local</code> or <code>declare</code> builtins in the
+function that is currently executing.
+</p>
+<p>Local variables &quot;shadow&quot; variables with the same name declared at
+previous scopes.  For instance, a local variable declared in a function
+hides a global variable of the same name: references and assignments
+refer to the local variable, leaving the global variable unmodified.
+When the function returns, the global variable is once again visible.
+</p>
+<p>The shell uses <em>dynamic scoping</em> to control a variable&rsquo;s visibility
+within functions.
+With dynamic scoping, visible variables and their values
+are a result of the sequence of function calls that caused execution
+to reach the current function.
+The value of a variable that a function sees depends
+on its value within its caller, if any, whether that caller is
+the &quot;global&quot; scope or another shell function.
+This is also the value that a local variable
+declaration &quot;shadows&quot;, and the value that is restored when the function
+returns.
+</p>
+<p>For example, if a variable <code>var</code> is declared as local in function
+<code>func1</code>, and <code>func1</code> calls another function <code>func2</code>,
+references to <code>var</code> made from within <code>func2</code> will resolve to the
+local variable <code>var</code> from <code>func1</code>, shadowing any global variable
+named <code>var</code>.
+</p>
+<p>The following script demonstrates this behavior.
+When executed, the script displays
+</p>
+<div class="example">
+<pre class="example">In func2, var = func1 local
+</pre></div>
+
+<div class="example">
+<pre class="example">func1()
+{
+    local var='func1 local'
+    func2
+}
+
+func2()
+{
+    echo &quot;In func2, var = $var&quot;
+}
+
+var=global
+func1
+</pre></div>
+
+<p>The <code>unset</code> builtin also acts using the same dynamic scope: if a  
+variable is local to the current scope, <code>unset</code> will unset it;         
+otherwise the unset will refer to the variable found in any calling scope 
+as described above.
+If a variable at the current local scope is unset, it will remain so
+(appearing as unset)
+until it is reset in that scope or until the function returns.
+Once the function returns, any instance of the variable at a previous
+scope will become visible.
+If the unset acts on a variable at a previous scope, any instance of a   
+variable with that name that had been shadowed will become visible
+(see below how <code>localvar_unset</code>shell option changes this behavior).
+</p>
+<p>Function names and definitions may be listed with the
+<samp>-f</samp> option to the <code>declare</code> (<code>typeset</code>)
+builtin command (see <a href="#Bash-Builtins">Bash Builtin Commands</a>).
+The <samp>-F</samp> option to <code>declare</code> or <code>typeset</code>
+will list the function names only
+(and optionally the source file and line number, if the <code>extdebug</code>
+shell option is enabled).
+Functions may be exported so that child shell processes
+(those created when executing a separate shell invocation)
+automatically have them defined with the
+<samp>-f</samp> option to the <code>export</code> builtin
+(see <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>).
+</p>
+<p>Functions may be recursive.
+The <code>FUNCNEST</code> variable may be used to limit the depth of the
+function call stack and restrict the number of function invocations.
+By default, no limit is placed on the number of recursive  calls.

+
+<p>A <em>parameter</em> is an entity that stores values.
+It can be a <code>name</code>, a number, or one of the special characters
+listed below.
+A <em>variable</em> is a parameter denoted by a <code>name</code>.
+A variable has a <code>value</code> and zero or more <code>attributes</code>.
+Attributes are assigned using the <code>declare</code> builtin command
+(see the description of the <code>declare</code> builtin in <a href="#Bash-Builtins">Bash Builtin Commands</a>).
+</p>
+<p>A parameter is set if it has been assigned a value.  The null string is
+a valid value.  Once a variable is set, it may be unset only by using
+the <code>unset</code> builtin command.
+</p>
+<p>A variable may be assigned to by a statement of the form
+</p><div class="example">
+<pre class="example"><var>name</var>=[<var>value</var>]
+</pre></div>
+<p>If <var>value</var>
+is not given, the variable is assigned the null string.  All
+<var>value</var>s undergo tilde expansion, parameter and variable expansion,
+command substitution, arithmetic expansion, and quote
+removal (see <a href="#Shell-Parameter-Expansion">Shell Parameter Expansion</a>).
+If the variable has its <code>integer</code>
+attribute set, then <var>value</var> 
+is evaluated as an arithmetic expression even if the <code>$((&hellip;))</code>
+expansion is not used (see <a href="#Arithmetic-Expansion">Arithmetic Expansion</a>).
+Word splitting and filename expansion are not performed.
+Assignment statements may also appear as arguments to the
+<code>alias</code>, 
+<code>declare</code>, <code>typeset</code>, <code>export</code>, <code>readonly</code>,
+and <code>local</code> builtin commands (<em>declaration</em> commands).
+When in <small>POSIX</small> mode (see <a href="#Bash-POSIX-Mode">Bash POSIX Mode</a>), these builtins may appear
+in a command after one or more instances of the <code>command</code> builtin
+and retain these assignment statement properties.
+</p>
+<p>In the context where an assignment statement is assigning a value  
+to a shell variable or array index (see <a href="#Arrays">Arrays</a>), the &lsquo;<samp>+=</samp>&rsquo;
+operator can be used to   
+append to or add to the variable&rsquo;s previous value.
+This includes arguments to builtin commands such as <code>declare</code> that
+accept assignment statements (declaration commands).
+When &lsquo;<samp>+=</samp>&rsquo; is applied to a variable for which the <code>integer</code> attribute
+has been set, <var>value</var> is evaluated as an arithmetic expression and
+added to the variable&rsquo;s current value, which is also evaluated.
+When &lsquo;<samp>+=</samp>&rsquo; is applied to an array variable using compound assignment
+(see <a href="#Arrays">Arrays</a>), the
+variable&rsquo;s value is not unset (as it is when using &lsquo;<samp>=</samp>&rsquo;), and new
+values are appended to the array beginning at one greater than the array&rsquo;s
+maximum index (for indexed arrays),  or added as additional key-value pairs
+in an associative array.
+When applied to a string-valued variable, <var>value</var> is expanded and
+appended to the variable&rsquo;s value.
+</p>
+<p>A variable can be assigned the <code>nameref</code> attribute using the
+<samp>-n</samp> option to the <code>declare</code> or <code>local</code> builtin commands
+(see <a href="#Bash-Builtins">Bash Builtin Commands</a>)
+to create a <em>nameref</em>, or a reference to another variable.
+This allows variables to be manipulated indirectly.
+Whenever the nameref variable is referenced, assigned to, unset, or has
+its attributes modified (other than using or changing the nameref
+attribute itself), the
+operation is actually performed on the variable specified by the nameref
+variable&rsquo;s value.
+A nameref is commonly used within shell functions to refer to a variable
+whose name is passed as an argument to the function.
+For instance, if a variable name is passed to a shell function as its first
+argument, running
+</p><div class="example">
+<pre class="example">declare -n ref=$1
+</pre></div>
+<p>inside the function creates a nameref variable <code>ref</code> whose value is
+the variable name passed as the first argument.
+References and assignments to <code>ref</code>, and changes to its attributes,
+are treated as references, assignments, and attribute modifications
+to the variable whose name was passed as <code>$1</code>.
+</p>
+<p>If the control variable in a <code>for</code> loop has the nameref attribute,
+the list of words can be a list of shell variables, and a name reference
+will be established for each word in the list, in turn, when the loop is
+executed.
+Array variables cannot be given the nameref attribute.
+However, nameref variables can reference array variables and subscripted
+array variables.
+Namerefs can be unset using the <samp>-n</samp> option to the <code>unset</code> builtin
+(see <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>).
+Otherwise, if <code>unset</code> is executed with the name of a nameref variable
+as an argument, the variable referenced by the nameref variable will be unset.

+Positional parameter <code>N</code> may be referenced as <code>${N}</code>, or

+Positional parameters may not be assigned to with assignment statements.
+The <code>set</code> and <code>shift</code> builtins are used to set and

+The positional parameters are
+temporarily replaced when a shell function is executed

+
+<p>Brace expansion is a mechanism by which arbitrary strings may be generated.
+This mechanism is similar to
+<em>filename expansion</em> (see <a href="#Filename-Expansion">Filename Expansion</a>),
+but the filenames generated need not exist.
+Patterns to be brace expanded take the form of an optional <var>preamble</var>,
+followed by either a series of comma-separated strings or a sequence expression
+between a pair of braces,
+followed by an optional <var>postscript</var>.
+The preamble is prefixed to each string contained within the braces, and
+the postscript is then appended to each resulting string, expanding left
+to right.
+</p>
+<p>Brace expansions may be nested.
+The results of each expanded string are not sorted; left to right order
+is preserved.
+For example,
+</p><div class="example">
+<pre class="example">bash$ echo a{d,c,b}e
+ade ace abe
+</pre></div>
+
+<p>A sequence expression takes the form <code>{<var>x</var>..<var>y</var>[..<var>incr</var>]}</code>,
+where <var>x</var> and <var>y</var> are either integers or letters,
+and <var>incr</var>, an optional increment, is an integer.
+When integers are supplied, the expression expands to each number between
+<var>x</var> and <var>y</var>, inclusive.
+Supplied integers may be prefixed with &lsquo;<samp>0</samp>&rsquo; to force each term to have the
+same width.
+When either <var>x</var> or <var>y</var> begins with a zero, the shell
+attempts to force all generated terms to contain the same number of digits,
+zero-padding where necessary.
+When letters are supplied, the expression expands to each character
+lexicographically between <var>x</var> and <var>y</var>, inclusive,
+using the default C locale.
+Note that both <var>x</var> and <var>y</var> must be of the same type
+(integer or letter).
+When the increment is supplied, it is used as the difference between
+each term.  The default increment is 1 or -1 as appropriate.
+</p>
+<p>Brace expansion is performed before any other expansions,
+and any characters special to other expansions are preserved
+in the result.  It is strictly textual.  Bash
+does not apply any syntactic interpretation to the context of the
+expansion or the text between the braces.
+</p>
+<p>A correctly-formed brace expansion must contain unquoted opening
+and closing braces, and at least one unquoted comma or a valid
+sequence expression.
+Any incorrectly formed brace expansion is left unchanged.
+</p>
+<p>A { or &lsquo;<samp>,</samp>&rsquo; may be quoted with a backslash to prevent its
+being considered part of a brace expression.
+To avoid conflicts with parameter expansion, the string &lsquo;<samp>${</samp>&rsquo;
+is not considered eligible for brace expansion,
+and inhibits brace expansion until the closing &lsquo;<samp>}</samp>&rsquo;.
+</p>
+<p>This construct is typically used as shorthand when the common
+prefix of the strings to be generated is longer than in the
+above example:
+</p><div class="example">
+<pre class="example">mkdir /usr/local/src/bash/{old,new,dist,bugs}
+</pre></div>
+<p>or
+</p><div class="example">
+<pre class="example">chown root /usr/{ucb/{ex,edit},lib/{ex?.?*,how_ex}}
+</pre></div>

+
+<p>If a word begins with an unquoted tilde character (&lsquo;<samp>~</samp>&rsquo;), all of the
+characters up to the first unquoted slash (or all characters,
+if there is no unquoted slash) are considered a <em>tilde-prefix</em>.
+If none of the characters in the tilde-prefix are quoted, the
+characters in the tilde-prefix following the tilde are treated as a
+possible <em>login name</em>.
+If this login name is the null string, the tilde is replaced with the
+value of the <code>HOME</code> shell variable.
+If <code>HOME</code> is unset, the home directory of the user executing the
+shell is substituted instead.
+Otherwise, the tilde-prefix is replaced with the home directory
+associated with the specified login name.
+</p>
+<p>If the tilde-prefix is &lsquo;<samp>~+</samp>&rsquo;, the value of
+the shell variable <code>PWD</code> replaces the tilde-prefix.
+If the tilde-prefix is &lsquo;<samp>~-</samp>&rsquo;, the value of the shell variable
+<code>OLDPWD</code>, if it is set, is substituted.
+</p>
+<p>If the characters following the tilde in the tilde-prefix consist of a
+number <var>N</var>, optionally prefixed by a &lsquo;<samp>+</samp>&rsquo; or a &lsquo;<samp>-</samp>&rsquo;,
+the tilde-prefix is replaced with the
+corresponding element from the directory stack, as it would be displayed
+by the <code>dirs</code> builtin invoked with the characters following tilde
+in the tilde-prefix as an argument (see <a href="#The-Directory-Stack">The Directory Stack</a>).
+If the tilde-prefix, sans the tilde, consists of a number without a
+leading &lsquo;<samp>+</samp>&rsquo; or &lsquo;<samp>-</samp>&rsquo;, &lsquo;<samp>+</samp>&rsquo; is assumed.
+</p>
+<p>If the login name is invalid, or the tilde expansion fails, the word is
+left unchanged.
+</p>
+<p>Each variable assignment is checked for unquoted tilde-prefixes immediately
+following a &lsquo;<samp>:</samp>&rsquo; or the first &lsquo;<samp>=</samp>&rsquo;.
+In these cases, tilde expansion is also performed.
+Consequently, one may use filenames with tildes in assignments to
+<code>PATH</code>, <code>MAILPATH</code>, and <code>CDPATH</code>,
+and the shell assigns the expanded value.
+</p>
+<p>The following table shows how Bash treats unquoted tilde-prefixes:
+</p>

+
+<p>The &lsquo;<samp>$</samp>&rsquo; character introduces parameter expansion,
+command substitution, or arithmetic expansion.  The parameter name
+or symbol to be expanded may be enclosed in braces, which
+are optional but serve to protect the variable to be expanded from
+characters immediately following it which could be
+interpreted as part of the name.
+</p>
+<p>When braces are used, the matching ending brace is the first &lsquo;<samp>}</samp>&rsquo;
+not escaped by a backslash or within a quoted string, and not within an
+embedded arithmetic expansion, command substitution, or parameter
+expansion.
+</p>
+<p>The basic form of parameter expansion is ${<var>parameter</var>}.
+The value of <var>parameter</var> is substituted.
+The <var>parameter</var> is a shell parameter as described above
+(see <a href="#Shell-Parameters">Shell Parameters</a>) or an array reference (see <a href="#Arrays">Arrays</a>).
+The braces are required when <var>parameter</var>
+is a positional parameter with more than one digit,
+or when <var>parameter</var> is followed by a character that is not to be
+interpreted as part of its name.
+</p>
+<p>If the first character of <var>parameter</var> is an exclamation point (!),
+and <var>parameter</var> is not a nameref,
+it introduces a level of indirection.
+Bash uses the value formed by expanding the rest of
+<var>parameter</var> as the new <var>parameter</var>; this is then
+expanded and that value is used in the rest of the expansion, rather
+than the expansion of the original <var>parameter</var>.
+This is known as <code>indirect expansion</code>.
+The value is subject to tilde expansion,
+parameter expansion, command substitution, and arithmetic expansion.
+If <var>parameter</var> is a nameref, this expands to the name of the
+variable referenced by <var>parameter</var> instead of performing the
+complete indirect expansion.
+The exceptions to this are the expansions of ${!<var>prefix</var>*}
+and ${!<var>name</var>[@]}
+described below.
+The exclamation point must immediately follow the left brace in order to
+introduce indirection.
+</p>
+<p>In each of the cases below, <var>word</var> is subject to tilde expansion,
+parameter expansion, command substitution, and arithmetic expansion.
+</p>
+<p>When not performing substring expansion, using the form described
+below (e.g., &lsquo;<samp>:-</samp>&rsquo;), Bash tests for a parameter that is unset or null.
+Omitting the colon results in a test only for a parameter that is unset.
+Put another way, if the colon is included,
+the operator tests for both <var>parameter</var>&rsquo;s existence and that its value
+is not null; if the colon is omitted, the operator tests only for existence.

+<dd><p>This is referred to as Substring Expansion.
+It expands to up to <var>length</var> characters of the value of <var>parameter</var>
+starting at the character specified by <var>offset</var>.
+If <var>parameter</var> is &lsquo;<samp>@</samp>&rsquo; or &lsquo;<samp>*</samp>&rsquo;, an indexed array subscripted by
+&lsquo;<samp>@</samp>&rsquo; or &lsquo;<samp>*</samp>&rsquo;, or an associative array name, the results differ as
+described below.
+If <var>length</var> is omitted, it expands to the substring of the value of
+<var>parameter</var> starting at the character specified by <var>offset</var>
+and extending to the end of the value.
+<var>length</var> and <var>offset</var> are arithmetic expressions
+(see <a href="#Shell-Arithmetic">Shell Arithmetic</a>).
+</p>
+<p>If <var>offset</var> evaluates to a number less than zero, the value
+is used as an offset in characters
+from the end of the value of <var>parameter</var>.
+If <var>length</var> evaluates to a number less than zero,
+it is interpreted as an offset in characters
+from the end of the value of <var>parameter</var> rather than
+a number of characters, and the expansion is the characters between
+<var>offset</var> and that result.
+Note that a negative offset must be separated from the colon by at least
+one space to avoid being confused with the &lsquo;<samp>:-</samp>&rsquo; expansion.
+</p>
+<p>Here are some examples illustrating substring expansion on parameters and
+subscripted arrays:

+<p>If <var>parameter</var> is &lsquo;<samp>@</samp>&rsquo; or &lsquo;<samp>*</samp>&rsquo;, the result is <var>length</var>
+positional parameters beginning at <var>offset</var>.
+A negative <var>offset</var> is taken relative to one greater than the greatest
+positional parameter, so an offset of -1 evaluates to the last positional
+parameter.
+It is an expansion error if <var>length</var> evaluates to a number less than zero.
+</p>
+<p>The following examples illustrate substring expansion using positional
+parameters:
+</p>
+<pre class="verbatim">$ set -- 1 2 3 4 5 6 7 8 9 0 a b c d e f g h

+
+</pre>
+<p>If <var>parameter</var> is an indexed array name subscripted

+A negative <var>offset</var> is taken relative to one greater than the maximum
+index of the specified array.
+It is an expansion error if <var>length</var> evaluates to a number less than zero.
+</p>
+<p>These examples show how you can use substring expansion with indexed
+arrays:
+</p>
+<pre class="verbatim">$ array=(0 1 2 3 4 5 6 7 8 9 0 a b c d e f g h)
+$ echo ${array[@]:7}

+0 1
+$ echo ${array[@]: -7:0}
+
+</pre>
+<p>Substring expansion applied to an associative array produces undefined
+results.
+</p>
+<p>Substring indexing is zero-based unless the positional parameters
+are used, in which case the indexing starts at 1 by default.

+<p>Quoting any part of <var>string</var> inhibits replacement in the
+expansion of the quoted portion, including replacement strings stored
+in shell variables.
+Backslash will escape &lsquo;<samp>&amp;</samp>&rsquo; in <var>string</var>; the backslash is removed
+in order to permit a literal &lsquo;<samp>&amp;</samp>&rsquo; in the replacement string.
+Users should take care if <var>string</var> is double-quoted to avoid
+unwanted interactions between the backslash and double-quoting, since
+backslash has special meaning within double quotes.
+Pattern substitution performs the check for unquoted &lsquo;<samp>&amp;</samp>&rsquo; after
+expanding <var>string</var>,
+so users should ensure to properly quote any occurrences of &lsquo;<samp>&amp;</samp>&rsquo;
+they want to be taken literally in the replacement
+and ensure any instances of &lsquo;<samp>&amp;</samp>&rsquo; they want to be replaced are unquoted.
+</p>
+<p>For instance,
+</p>
+<div class="example">
+<pre class="example">var=abcdef
+rep='&amp; '
+echo ${var/abc/&amp; }
+echo &quot;${var/abc/&amp; }&quot;
+echo ${var/abc/$rep}
+echo &quot;${var/abc/$rep}&quot;
+</pre></div>
+
+<p>will display four lines of &quot;abc def&quot;, while
+</p>
+<div class="example">
+<pre class="example">var=abcdef
+rep='&amp; '
+echo ${var/abc/\&amp; }
+echo &quot;${var/abc/\&amp; }&quot;
+echo ${var/abc/&quot;&amp; &quot;}
+echo ${var/abc/&quot;$rep&quot;}
+</pre></div>
+
+<p>will display four lines of &quot;&amp; def&quot;.
+Like the pattern removal operators, double quotes surrounding the
+replacement string quote the expanded characters, while double quotes
+enclosing the entire parameter substitution do not, since
+the expansion is performed in a
+context that doesn&rsquo;t take any enclosing double quotes into account.
+</p>
+<p>Since backslash can escape &lsquo;<samp>&amp;</samp>&rsquo;, it can also escape a backslash in
+the replacement string.
+This means that &lsquo;<samp>\\</samp>&rsquo; will insert a literal
+backslash into the replacement, so these two <code>echo</code> commands
+</p>
+<div class="example">
+<pre class="example">var=abcdef
+rep='\\&amp;xyz'
+echo ${var/abc/\\&amp;xyz}
+echo ${var/abc/$rep}
+</pre></div>
+
+<p>will both output &lsquo;<samp>\abcxyzdef</samp>&rsquo;.
+</p>
+<p>It should rarely be necessary to enclose only <var>string</var> in double
+quotes.
+</p>
+<p>If the <code>nocasematch</code> shell option   
+(see the description of <code>shopt</code> in <a href="#The-Shopt-Builtin">The Shopt Builtin</a>)
+is enabled, the match is performed without regard to the case   
+of alphabetic characters.
+If <var>parameter</var> is &lsquo;<samp>@</samp>&rsquo; or &lsquo;<samp>*</samp>&rsquo;,
+the substitution operation is applied to each positional
+parameter in turn, and the expansion is the resultant list.
+If <var>parameter</var>

+<p>Command substitution allows the output of a command to replace
+the command itself.
+Command substitution occurs when a command is enclosed as follows:
+</p><div class="example">
+<pre class="example">$(<var>command</var>)
+</pre></div>
+<p>or
+</p><div class="example">
+<pre class="example">`<var>command</var>`
+</pre></div>
+
+<p>Bash performs the expansion by executing <var>command</var> in a subshell environment
+and replacing the command substitution with the standard output of the
+command, with any trailing newlines deleted.
+Embedded newlines are not deleted, but they may be removed during
+word splitting.
+The command substitution <code>$(cat <var>file</var>)</code> can be
+replaced by the equivalent but faster <code>$(&lt; <var>file</var>)</code>.
+</p>
+<p>When the old-style backquote form of substitution is used,
+backslash retains its literal meaning except when followed by
+&lsquo;<samp>$</samp>&rsquo;, &lsquo;<samp>`</samp>&rsquo;, or &lsquo;<samp>\</samp>&rsquo;. 
+The first backquote not preceded by a backslash terminates the
+command substitution.
+When using the <code>$(<var>command</var>)</code> form, all characters between
+the parentheses make up the command; none are treated specially.
+</p>
+<p>Command substitutions may be nested.  To nest when using the backquoted
+form, escape the inner backquotes with backslashes.
+</p>
+<p>If the substitution appears within double quotes, word splitting and
+filename expansion are not performed on the results.

+<div class="example">

+Note that no space may appear between the <code>&lt;</code> or <code>&gt;</code>

+Process substitution is supported on systems that support named

+
+<p>The shell scans the results of parameter expansion, command substitution,
+and arithmetic expansion that did not occur within double quotes for
+word splitting.
+</p>
+<p>The shell treats each character of <code>$IFS</code> as a delimiter, and splits
+the results of the other expansions into words using these characters
+as field terminators.
+If <code>IFS</code> is unset, or its value is exactly <code>&lt;space&gt;&lt;tab&gt;&lt;newline&gt;</code>,
+the default, then sequences of
+<code> &lt;space&gt;</code>, <code>&lt;tab&gt;</code>, and <code>&lt;newline&gt;</code>
+at the beginning and end of the results of the previous
+expansions are ignored, and any sequence of <code>IFS</code>
+characters not at the beginning or end serves to delimit words.
+If <code>IFS</code> has a value other than the default, then sequences of
+the whitespace characters <code>space</code>, <code>tab</code>, and <code>newline</code>
+are ignored at the beginning and end of the
+word, as long as the whitespace character is in the
+value of <code>IFS</code> (an <code>IFS</code> whitespace character).
+Any character in <code>IFS</code> that is not <code>IFS</code>
+whitespace, along with any adjacent <code>IFS</code>
+whitespace characters, delimits a field.  A sequence of <code>IFS</code>
+whitespace characters is also treated as a delimiter.
+If the value of <code>IFS</code> is null, no word splitting occurs.
+</p>
+<p>Explicit null arguments (<code>&quot;&quot;</code> or <code>''</code>) are retained
+and passed to commands as empty strings.
+Unquoted implicit null arguments, resulting from the expansion of
+parameters that have no values, are removed.
+If a parameter with no value is expanded within double quotes, a
+null argument results and is retained
+and passed to a command as an empty string.
+When a quoted null argument appears as part of a word whose expansion is
+non-null, the null argument is removed.
+That is, the word
+<code>-d''</code> becomes <code>-d</code> after word splitting and

+<p>After word splitting, unless the <samp>-f</samp> option has been set
+(see <a href="#The-Set-Builtin">The Set Builtin</a>), Bash scans each word for the characters
+&lsquo;<samp>*</samp>&rsquo;, &lsquo;<samp>?</samp>&rsquo;, and &lsquo;<samp>[</samp>&rsquo;.
+If one of these characters appears, and is not quoted, then the word is
+regarded as a <var>pattern</var>,
+and replaced with an alphabetically sorted list of
+filenames matching the pattern (see <a href="#Pattern-Matching">Pattern Matching</a>).
+If no matching filenames are found,
+and the shell option <code>nullglob</code> is disabled, the word is left
+unchanged.
+If the <code>nullglob</code> option is set, and no matches are found, the word
+is removed.
+If the <code>failglob</code> shell option is set, and no matches are found,
+an error message is printed and the command is not executed.
+If the shell option <code>nocaseglob</code> is enabled, the match is performed
+without regard to the case of alphabetic characters.
+</p>
+<p>When a pattern is used for filename expansion, the character &lsquo;<samp>.</samp>&rsquo;
+at the start of a filename or immediately following a slash
+must be matched explicitly, unless the shell option <code>dotglob</code> is set.
+In order to match the filenames &lsquo;<samp>.</samp>&rsquo; and &lsquo;<samp>..</samp>&rsquo;,
+the pattern must begin with &lsquo;<samp>.</samp>&rsquo; (for example, &lsquo;<samp>.?</samp>&rsquo;),
+even if <code>dotglob</code> is set.

+&lsquo;<samp>.</samp>&rsquo; and &lsquo;<samp>..</samp>&rsquo; are never matched, even if the pattern begins
+with a &lsquo;<samp>.</samp>&rsquo;.
+When not matching filenames, the &lsquo;<samp>.</samp>&rsquo; character is not treated specially.
+</p>
+<p>When matching a filename, the slash character must always be

+<p>The <code>GLOBIGNORE</code>
+shell variable may be used to restrict the set of file names matching a
+pattern.  If <code>GLOBIGNORE</code>
+is set, each matching file name that also matches one of the patterns in
+<code>GLOBIGNORE</code> is removed from the list of matches.
+If the <code>nocaseglob</code> option is set, the matching against the patterns in
+<code>GLOBIGNORE</code> is performed without regard to case.
+The filenames
+<samp>.</samp> and <samp>..</samp>
+are always ignored when <code>GLOBIGNORE</code>
+is set and not null.
+However, setting <code>GLOBIGNORE</code> to a non-null value has the effect of

+shell option, so all other filenames beginning with a

+To get the old behavior of ignoring filenames beginning with a
+&lsquo;<samp>.</samp>&rsquo;, make &lsquo;<samp>.*</samp>&rsquo; one of the patterns in <code>GLOBIGNORE</code>.
+The <code>dotglob</code> option is disabled when <code>GLOBIGNORE</code>

+<dt><span><code>[&hellip;]</code></span></dt>
+<dd><p>Matches any one of the enclosed characters.  A pair of characters
+separated by a hyphen denotes a <var>range expression</var>;
+any character that falls between those two characters, inclusive,
+using the current locale&rsquo;s collating sequence and character set,

+&lsquo;<samp>[</samp>&rsquo; is a &lsquo;<samp>!</samp>&rsquo;  or a &lsquo;<samp>^</samp>&rsquo;
+then any character not enclosed is matched.  A &lsquo;<samp>-</samp>&rsquo;
+may be matched by including it as the first or last character
+in the set.  A &lsquo;<samp>]</samp>&rsquo; may be matched by including it as the first
+character in the set.
+The sorting order of characters in range expressions,
+and the characters included in the range,
+are determined by
+the current locale and the values of the
+<code>LC_COLLATE</code> and <code>LC_ALL</code> shell variables, if set.
+</p>
+<p>For example, in the default C locale, &lsquo;<samp>[a-dx-z]</samp>&rsquo; is equivalent to
+&lsquo;<samp>[abcdxyz]</samp>&rsquo;.  Many locales sort characters in dictionary order, and in
+these locales &lsquo;<samp>[a-dx-z]</samp>&rsquo; is typically not equivalent to &lsquo;<samp>[abcdxyz]</samp>&rsquo;;
+it might be equivalent to &lsquo;<samp>[aBbCcDdxYyZz]</samp>&rsquo;, for example.  To obtain
+the traditional interpretation of ranges in bracket expressions, you can
+force the use of the C locale by setting the <code>LC_COLLATE</code> or
+<code>LC_ALL</code> environment variable to the value &lsquo;<samp>C</samp>&rsquo;, or enable the
+<code>globasciiranges</code> shell option.
+</p>
+<p>Within &lsquo;<samp>[</samp>&rsquo; and &lsquo;<samp>]</samp>&rsquo;, <em>character classes</em> can be specified
+using the syntax
+<code>[:</code><var>class</var><code>:]</code>, where <var>class</var> is one of the
+following classes defined in the <small>POSIX</small> standard:
+</p><div class="example">
+<pre class="example">alnum   alpha   ascii   blank   cntrl   digit   graph   lower
+print   punct   space   upper   word    xdigit
+</pre></div>
+<p>A character class matches any character belonging to that class.
+The <code>word</code> character class matches letters, digits, and the character
+&lsquo;<samp>_</samp>&rsquo;.
+</p>
+<p>Within &lsquo;<samp>[</samp>&rsquo; and &lsquo;<samp>]</samp>&rsquo;, an <em>equivalence class</em> can be
+specified using the syntax <code>[=</code><var>c</var><code>=]</code>, which
+matches all characters with the same collation weight (as defined
+by the current locale) as the character <var>c</var>.
+</p>
+<p>Within &lsquo;<samp>[</samp>&rsquo; and &lsquo;<samp>]</samp>&rsquo;, the syntax <code>[.</code><var>symbol</var><code>.]</code>
+matches the collating symbol <var>symbol</var>.
+</p></dd>
+</dl>
+
+<p>If the <code>extglob</code> shell option is enabled using the <code>shopt</code>
+builtin, the shell recognizes several extended pattern matching operators.
+In the following description, a <var>pattern-list</var> is a list of one
+or more patterns separated by a &lsquo;<samp>|</samp>&rsquo;.
+When matching filenames, the <code>dotglob</code> shell option determines

+<p>The <code>extglob</code> option changes the behavior of the parser, since the

+To ensure that extended matching patterns are parsed correctly, make sure
+that <code>extglob</code> is enabled before parsing constructs containing the
+patterns, including shell functions and command substitutions.
+</p>
+<p>When matching filenames, the <code>dotglob</code> shell option determines
+the set of filenames that are tested:
+when <code>dotglob</code> is enabled, the set of filenames includes all files
+beginning with &lsquo;<samp>.</samp>&rsquo;, but the filenames
+&lsquo;<samp>.</samp>&rsquo; and &lsquo;<samp>..</samp>&rsquo; must be matched by a
+pattern or sub-pattern that begins with a dot;
+when it is disabled, the set does not
+include any filenames beginning with &ldquo;.&rdquo; unless the pattern
+or sub-pattern begins with a &lsquo;<samp>.</samp>&rsquo;.
+As above, &lsquo;<samp>.</samp>&rsquo; only has a special meaning when matching filenames. 
+</p>
+<p>Complicated extended pattern matching against long strings is slow,
+especially when the patterns contain alternations and the strings
+contain multiple matches.
+Using separate matches against shorter strings, or using arrays of

+<span id="Redirections-1"></span><h3 class="section">3.6 Redirections</h3>
+<span id="index-redirection"></span>
+
+<p>Before a command is executed, its input and output
+may be <em>redirected</em>
+using a special notation interpreted by the shell.
+<em>Redirection</em> allows commands&rsquo; file handles to be
+duplicated, opened, closed,
+made to refer to different files,
+and can change the files the command reads from and writes to.
+Redirection may also be used to modify file handles in the
+current shell execution environment.  The following redirection
+operators may precede or appear anywhere within a
+simple command or may follow a command.
+Redirections are processed in the order they appear, from
+left to right.
+</p>
+<p>Each redirection that may be preceded by a file descriptor number
+may instead be preceded by a word of the form {<var>varname</var>}.
+In this case, for each redirection operator except
+&gt;&amp;- and &lt;&amp;-, the shell will allocate a file descriptor greater
+than 10 and assign it to {<var>varname</var>}.  If &gt;&amp;- or &lt;&amp;- is preceded
+by {<var>varname</var>}, the value of <var>varname</var> defines the file
+descriptor to close.
+If {<var>varname</var>} is supplied, the redirection persists beyond
+the scope of the command, allowing the shell programmer to manage
+the file descriptor&rsquo;s lifetime manually.
+The <code>varredir_close</code> shell option manages this behavior
+(see <a href="#The-Shopt-Builtin">The Shopt Builtin</a>).
+</p>
+<p>In the following descriptions, if the file descriptor number is
+omitted, and the first character of the redirection operator is
+&lsquo;<samp>&lt;</samp>&rsquo;, the redirection refers to the standard input (file
+descriptor 0).  If the first character of the redirection operator
+is &lsquo;<samp>&gt;</samp>&rsquo;, the redirection refers to the standard output (file
+descriptor 1).
+</p>
+<p>The word following the redirection operator in the following
+descriptions, unless otherwise noted, is subjected to brace expansion,
+tilde expansion, parameter expansion, command substitution, arithmetic
+expansion, quote removal, filename expansion, and word splitting.
+If it expands to more than one word, Bash reports an error.
+</p>
+<p>Note that the order of redirections is significant.  For example,
+the command
+</p><div class="example">
+<pre class="example">ls &gt; <var>dirlist</var> 2&gt;&amp;1
+</pre></div>
+<p>directs both standard output (file descriptor 1) and standard error
+(file descriptor 2) to the file <var>dirlist</var>, while the command
+</p><div class="example">
+<pre class="example">ls 2&gt;&amp;1 &gt; <var>dirlist</var>
+</pre></div>
+<p>directs only the standard output to file <var>dirlist</var>,
+because the standard error was made a copy of the standard output
+before the standard output was redirected to <var>dirlist</var>.
+</p>
+<p>Bash handles several filenames specially when they are used in
+redirections, as described in the following table.
+If the operating system on which Bash is running provides these
+special files, bash will use them; otherwise it will emulate them
+internally with the behavior described below.
+</p>
+<dl compact="compact">
+<dt><span><code>/dev/fd/<var>fd</var></code></span></dt>
+<dd><p>If <var>fd</var> is a valid integer, file descriptor <var>fd</var> is duplicated.
+</p>

+<dd><p>File descriptor 0 is duplicated.

+<dd><p>If <var>host</var> is a valid hostname or Internet address, and <var>port</var>

+the corresponding TCP socket.
+</p>
+</dd>
+<dt><span><code>/dev/udp/<var>host</var>/<var>port</var></code></span></dt>
+<dd><p>If <var>host</var> is a valid hostname or Internet address, and <var>port</var>
+is an integer port number or service name, Bash attempts to open 
+the corresponding UDP socket.
+</p></dd>
+</dl>
+
+<p>A failure to open or create a file causes the redirection to fail.
+</p>
+<p>Redirections using file descriptors greater than 9 should be used with
+care, as they may conflict with file descriptors the shell uses
+internally.

+<p>If no command name results, the variable assignments affect the current

+In the case of such a command (one that consists only of assignment

+<ol>
+<li> If the command name contains no slashes, the shell attempts to
+locate it.  If there exists a shell function by that name, that
+function is invoked as described in <a href="#Shell-Functions">Shell Functions</a>.
+
+</li><li> If the name does not match a function, the shell searches for
+it in the list of shell builtins.  If a match is found, that
+builtin is invoked.
+
+</li><li> If the name is neither a shell function nor a builtin,
+and contains no slashes, Bash searches each element of
+<code>$PATH</code> for a directory containing an executable file
+by that name.  Bash uses a hash table to remember the full
+pathnames of executable files to avoid multiple <code>PATH</code> searches
+(see the description of <code>hash</code> in <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>).
+A full search of the directories in <code>$PATH</code>
+is performed only if the command is not found in the hash table.
+If the search is unsuccessful, the shell searches for a defined shell
+function named <code>command_not_found_handle</code>.
+If that function exists, it is invoked in a separate execution environment
+with the original command and
+the original command&rsquo;s arguments as its arguments, and the function&rsquo;s
+exit status becomes the exit status of that subshell.
+If that function is not defined, the shell prints an error
+message and returns an exit status of 127.
+
+</li><li> If the search is successful, or if the command name contains
+one or more slashes, the shell executes the named program in
+a separate execution environment.
+Argument 0 is set to the name given, and the remaining arguments
+to the command are set to the arguments supplied, if any.
+
+</li><li> If this execution fails because the file is not in executable

+<span id="index-environment"></span>
+
+<p>When a program is invoked it is given an array of strings
+called the <em>environment</em>.
+This is a list of name-value pairs, of the form <code>name=value</code>.
+</p>
+<p>Bash provides several ways to manipulate the environment.
+On invocation, the shell scans its own environment and
+creates a parameter for each name found, automatically marking
+it for <code>export</code>
+to child processes.  Executed commands inherit the environment.
+The <code>export</code> and &lsquo;<samp>declare -x</samp>&rsquo;
+commands allow parameters and functions to be added to and
+deleted from the environment.  If the value of a parameter
+in the environment is modified, the new value becomes part
+of the environment, replacing the old.  The environment
+inherited by any executed command consists of the shell&rsquo;s
+initial environment, whose values may be modified in the shell,
+less any pairs removed by the <code>unset</code> and &lsquo;<samp>export -n</samp>&rsquo;
+commands, plus any additions via the <code>export</code> and
+&lsquo;<samp>declare -x</samp>&rsquo; commands.
+</p>
+<p>The environment for any simple command
+or function may be augmented temporarily by prefixing it with
+parameter assignments, as described in <a href="#Shell-Parameters">Shell Parameters</a>.
+These assignment statements affect only the environment seen
+by that command.
+</p>
+<p>If the <samp>-k</samp> option is set (see <a href="#The-Set-Builtin">The Set Builtin</a>), then all
+parameter assignments are placed in the environment for a command,
+not just those that precede the command name.
+</p>
+<p>When Bash invokes an external command, the variable &lsquo;<samp>$_</samp>&rsquo;
+is set to the full pathname of the command and passed to that
+command in its environment.

+<span id="Exit-Status-1"></span><h4 class="subsection">3.7.5 Exit Status</h4>
+<span id="index-exit-status-1"></span>
+
+<p>The exit status of an executed command is the value returned by the
+<code>waitpid</code> system call or equivalent function.  Exit statuses    
+fall between 0 and 255, though, as explained below, the shell may
+use values above 125 specially.  Exit statuses from shell builtins and
+compound commands are also limited to this range.  Under certain
+circumstances, the shell will use special values to indicate specific
+failure modes.
+</p>
+<p>For the shell&rsquo;s purposes, a command which exits with a
+zero exit status has succeeded.
+A non-zero exit status indicates failure.
+This seemingly counter-intuitive scheme is used so there
+is one well-defined way to indicate success and a variety of
+ways to indicate various failure modes.
+When a command terminates on a fatal signal whose number is <var>N</var>,
+Bash uses the value 128+<var>N</var> as the exit status.
+</p>
+<p>If a command is not found, the child process created to
+execute it returns a status of 127.  If a command is found  
+but is not executable, the return status is 126.
+</p>
+<p>If a command fails because of an error during expansion or redirection,
+the exit status is greater than zero.
+</p>
+<p>The exit status is used by the Bash conditional commands
+(see <a href="#Conditional-Constructs">Conditional Constructs</a>) and some of the list
+constructs (see <a href="#Lists">Lists of Commands</a>).
+</p>
+<p>All of the Bash builtins return an exit status of zero if they succeed
+and a non-zero status on failure, so they may be used by the
+conditional and list constructs.
+All builtins return an exit status of 2 to indicate incorrect usage,
+generally invalid options or missing arguments.
+</p>
+<p>The exit status of the last command is available in the special
+parameter $? (see <a href="#Special-Parameters">Special Parameters</a>).

+<span id="Signals-1"></span><h4 class="subsection">3.7.6 Signals</h4>
+<span id="index-signal-handling"></span>
+
+<p>When Bash is interactive, in the absence of any traps, it ignores
+<code>SIGTERM</code> (so that &lsquo;<samp>kill 0</samp>&rsquo; does not kill an interactive shell),
+and <code>SIGINT</code>
+is caught and handled (so that the <code>wait</code> builtin is interruptible).
+When Bash receives a <code>SIGINT</code>, it breaks out of any executing loops.
+In all cases, Bash ignores <code>SIGQUIT</code>.
+If job control is in effect (see <a href="#Job-Control">Job Control</a>), Bash
+ignores <code>SIGTTIN</code>, <code>SIGTTOU</code>, and <code>SIGTSTP</code>.
+</p>
+<p>Non-builtin commands started by Bash have signal handlers set to the
+values inherited by the shell from its parent.
+When job control is not in effect, asynchronous commands
+ignore <code>SIGINT</code> and <code>SIGQUIT</code> in addition to these inherited
+handlers.
+Commands run as a result of
+command substitution ignore the keyboard-generated job control signals
+<code>SIGTTIN</code>, <code>SIGTTOU</code>, and <code>SIGTSTP</code>.
+</p>
+<p>The shell exits by default upon receipt of a <code>SIGHUP</code>.
+Before exiting, an interactive shell resends the <code>SIGHUP</code> to
+all jobs, running or stopped.
+Stopped jobs are sent <code>SIGCONT</code> to ensure that they receive
+the <code>SIGHUP</code>.
+To prevent the shell from sending the <code>SIGHUP</code> signal to a
+particular job, it should be removed
+from the jobs table with the <code>disown</code>
+builtin (see <a href="#Job-Control-Builtins">Job Control Builtins</a>) or marked
+to not receive <code>SIGHUP</code> using <code>disown -h</code>.
+</p>
+<p>If the  <code>huponexit</code> shell option has been set with <code>shopt</code>
+(see <a href="#The-Shopt-Builtin">The Shopt Builtin</a>), Bash sends a <code>SIGHUP</code> to all jobs when
+an interactive login shell exits.
+</p>
+<p>If Bash is waiting for a command to complete and receives a signal
+for which a trap has been set, the trap will not be executed until
+the command completes.
+When Bash is waiting for an asynchronous
+command via the <code>wait</code> builtin, the reception of a signal for
+which a trap has been set will cause the <code>wait</code> builtin to return
+immediately with an exit status greater than 128, immediately after
+which the trap is executed.
+</p>
+<p>When job control is not enabled, and Bash is waiting for a foreground
+command to complete, the shell receives keyboard-generated signals
+such as <code>SIGINT</code> (usually generated by &lsquo;<samp>^C</samp>&rsquo;) that users
+commonly intend to send to that command.
+This happens because the shell and the command are in the same process
+group as the terminal, and &lsquo;<samp>^C</samp>&rsquo; sends <code>SIGINT</code> to all processes
+in that process group.
+See <a href="#Job-Control">Job Control</a>, for a more in-depth discussion of process groups.
+</p>
+<p>When Bash is running without job control enabled and receives <code>SIGINT</code>
+while waiting for a foreground command, it waits until that foreground
+command terminates and then decides what to do about the <code>SIGINT</code>:
+</p>
+<ol>
+<li> If the command terminates due to the <code>SIGINT</code>, Bash concludes
+that the user meant to end the entire script, and acts on the
+<code>SIGINT</code> (e.g., by running a <code>SIGINT</code> trap or exiting itself);
+
+</li><li> If the pipeline does not terminate due to <code>SIGINT</code>, the program
+handled the <code>SIGINT</code> itself and did not treat it as a fatal signal.
+In that case, Bash does not treat <code>SIGINT</code> as a fatal signal,
+either, instead assuming that the <code>SIGINT</code> was used as part of the
+program&rsquo;s normal operation (e.g., <code>emacs</code> uses it to abort editing
+commands) or deliberately discarded. However, Bash will run any
+trap set on <code>SIGINT</code>, as it does with any other trapped signal it
+receives while it is waiting for the foreground command to
+complete, for compatibility.

+<span id="Shell-Scripts-1"></span><h3 class="section">3.8 Shell Scripts</h3>
+<span id="index-shell-script"></span>
+
+<p>A shell script is a text file containing shell commands.  When such
+a file is used as the first non-option argument when invoking Bash,
+and neither the <samp>-c</samp> nor <samp>-s</samp> option is supplied
+(see <a href="#Invoking-Bash">Invoking Bash</a>), 
+Bash reads and executes commands from the file, then exits.  This
+mode of operation creates a non-interactive shell.  The shell first
+searches for the file in the current directory, and looks in the
+directories in <code>$PATH</code> if not found there.
+</p>
+<p>When Bash runs
+a shell script, it sets the special parameter <code>0</code> to the name
+of the file, rather than the name of the shell, and the positional
+parameters are set to the remaining arguments, if any are given.
+If no additional arguments are supplied, the positional parameters
+are unset.
+</p>
+<p>A shell script may be made executable by using the <code>chmod</code> command
+to turn on the execute bit.  When Bash finds such a file while
+searching the <code>$PATH</code> for a command, it creates a
+new instance of itself
+to execute it.
+In other words, executing
+</p><div class="example">
+<pre class="example">filename <var>arguments</var>
+</pre></div>
+<p>is equivalent to executing
+</p><div class="example">
+<pre class="example">bash filename <var>arguments</var>
+</pre></div>
+
+<p>if <code>filename</code> is an executable shell script.
+This subshell reinitializes itself, so that the effect is as if a
+new shell had been invoked to interpret the script, with the
+exception that the locations of commands remembered by the parent
+(see the description of <code>hash</code> in <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>)
+are retained by the child.
+</p>
+<p>Most versions of Unix make this a part of the operating system&rsquo;s command
+execution mechanism.  If the first line of a script begins with
+the two characters &lsquo;<samp>#!</samp>&rsquo;, the remainder of the line specifies
+an interpreter for the program and, depending on the operating system, one
+or more optional arguments for that interpreter.
+Thus, you can specify Bash, <code>awk</code>, Perl, or some other
+interpreter and write the rest of the script file in that language.
+</p>
+<p>The arguments to the interpreter
+consist of one or more optional arguments following the interpreter
+name on the first line of the script file, followed by the name of
+the script file, followed by the rest of the arguments supplied to the
+script.
+The details of how the interpreter line is split into an interpreter name
+and a set of arguments vary across systems.
+Bash will perform this action on operating systems that do not handle it
+themselves.
+Note that some older versions of Unix limit the interpreter
+name and a single argument to a maximum of 32 characters, so it&rsquo;s not
+portable to assume that using more than one argument will work.
+</p>
+<p>Bash scripts often begin with <code>#! /bin/bash</code> (assuming that
+Bash has been installed in <samp>/bin</samp>), since this ensures that
+Bash will be used to interpret the script, even if it is executed
+under another shell. It&rsquo;s a common idiom to use <code>env</code> to find
+<code>bash</code> even if it&rsquo;s been installed in another directory:
+<code>#!/usr/bin/env bash</code> will find the first occurrence of <code>bash</code>
+in <code>$PATH</code>.

+
+
+<p>Builtin commands are contained within the shell itself.
+When the name of a builtin command is used as the first word of
+a simple command (see <a href="#Simple-Commands">Simple Commands</a>), the shell executes
+the command directly, without invoking another program.
+Builtin commands are necessary to implement functionality impossible
+or inconvenient to obtain with separate utilities.
+</p>
+<p>This section briefly describes the builtins which Bash inherits from
+the Bourne Shell, as well as the builtin commands which are unique
+to or have been extended in Bash.
+</p>
+<p>Several builtin commands are described in other chapters: builtin
+commands which provide the Bash interface to the job control
+facilities (see <a href="#Job-Control-Builtins">Job Control Builtins</a>), the directory stack
+(see <a href="#Directory-Stack-Builtins">Directory Stack Builtins</a>), the command history
+(see <a href="#Bash-History-Builtins">Bash History Builtins</a>), and the programmable completion
+facilities (see <a href="#Programmable-Completion-Builtins">Programmable Completion Builtins</a>).
+</p>
+<p>Many of the builtins have been extended by <small>POSIX</small> or Bash.
+</p>
+<p>Unless otherwise noted, each builtin command documented as accepting
+options preceded by &lsquo;<samp>-</samp>&rsquo; accepts &lsquo;<samp>--</samp>&rsquo;
+to signify the end of the options.
+The <code>:</code>, <code>true</code>, <code>false</code>, and <code>test</code>/<code>[</code>
+builtins do not accept options and do not treat &lsquo;<samp>--</samp>&rsquo; specially.
+The <code>exit</code>, <code>logout</code>, <code>return</code>,
+<code>break</code>, <code>continue</code>, <code>let</code>,
+and <code>shift</code> builtins accept and process arguments beginning
+with &lsquo;<samp>-</samp>&rsquo; without requiring &lsquo;<samp>--</samp>&rsquo;.
+Other builtins that accept arguments but are not specified as accepting
+options interpret arguments beginning with &lsquo;<samp>-</samp>&rsquo; as invalid options and
+require &lsquo;<samp>--</samp>&rsquo; to prevent this interpretation.

+
+<p>Read and execute commands from the <var>filename</var> argument in the
+current shell context.  If <var>filename</var> does not contain a slash,
+the <code>PATH</code> variable is used to find <var>filename</var>,
+but <var>filename</var> does not need to be executable.
+When Bash is not in <small>POSIX</small> mode, it searches the current directory
+if <var>filename</var> is not found in <code>$PATH</code>.
+If any <var>arguments</var> are supplied, they become the positional
+parameters when <var>filename</var> is executed.  Otherwise the positional
+parameters are unchanged.
+If the <samp>-T</samp> option is enabled, <code>.</code> inherits any trap on
+<code>DEBUG</code>; if it is not, any <code>DEBUG</code> trap string is saved and
+restored around the call to <code>.</code>, and <code>.</code> unsets the
+<code>DEBUG</code> trap while it executes.
+If <samp>-T</samp> is not set, and the sourced file changes
+the <code>DEBUG</code> trap, the new value is retained when <code>.</code> completes.
+The return status is the exit status of the last command executed, or
+zero if no commands are executed.  If <var>filename</var> is not found, or
+cannot be read, the return status is non-zero.

+<var>directory</var>, with alternative directory names in <code>CDPATH</code>
+separated by a colon (&lsquo;<samp>:</samp>&rsquo;).
+If <var>directory</var> begins with a slash, <code>CDPATH</code> is not used.
+</p>
+<p>The <samp>-P</samp> option means to not follow symbolic links: symbolic links

+</p>
+<p>By default, or when the <samp>-L</samp> option is supplied, symbolic links

+<p>If &lsquo;<samp>..</samp>&rsquo; appears in <var>directory</var>, it is processed by removing the

+and the current working directory cannot be successfully determined

+<p>If the directory change is successful, <code>cd</code> sets the value of the

+
+<p><code>getopts</code> is used by shell scripts to parse positional parameters.
+<var>optstring</var> contains the option characters to be recognized; if a
+character is followed by a colon, the option is expected to have an
+argument, which should be separated from it by whitespace.
+The colon (&lsquo;<samp>:</samp>&rsquo;) and question mark (&lsquo;<samp>?</samp>&rsquo;) may not be
+used as option characters.
+Each time it is invoked, <code>getopts</code>
+places the next option in the shell variable <var>name</var>, initializing
+<var>name</var> if it does not exist,
+and the index of the next argument to be processed into the
+variable <code>OPTIND</code>.
+<code>OPTIND</code> is initialized to 1 each time the shell or a shell script
+is invoked.
+When an option requires an argument,
+<code>getopts</code> places that argument into the variable <code>OPTARG</code>.
+The shell does not reset <code>OPTIND</code> automatically; it must be manually
+reset between multiple calls to <code>getopts</code> within the same shell
+invocation if a new set of parameters is to be used.
+</p>
+<p>When the end of options is encountered, <code>getopts</code> exits with a
+return value greater than zero.
+<code>OPTIND</code> is set to the index of the first non-option argument,
+and <var>name</var> is set to &lsquo;<samp>?</samp>&rsquo;.
+</p>
+<p><code>getopts</code>
+normally parses the positional parameters, but if more arguments are
+supplied as <var>arg</var> values, <code>getopts</code> parses those instead.
+</p>
+<p><code>getopts</code> can report errors in two ways.  If the first character of
+<var>optstring</var> is a colon, <var>silent</var>
+error reporting is used.  In normal operation, diagnostic messages
+are printed when invalid options or missing option arguments are
+encountered.
+If the variable <code>OPTERR</code>
+is set to 0, no error messages will be displayed, even if the first
+character of <code>optstring</code> is not a colon.
+</p>
+<p>If an invalid option is seen,
+<code>getopts</code> places &lsquo;<samp>?</samp>&rsquo; into <var>name</var> and, if not silent,
+prints an error message and unsets <code>OPTARG</code>.
+If <code>getopts</code> is silent, the option character found is placed in
+<code>OPTARG</code> and no diagnostic message is printed.
+</p>
+<p>If a required argument is not found, and <code>getopts</code>
+is not silent, a question mark (&lsquo;<samp>?</samp>&rsquo;) is placed in <var>name</var>,
+<code>OPTARG</code> is unset, and a diagnostic message is printed.
+If <code>getopts</code> is silent, then a colon (&lsquo;<samp>:</samp>&rsquo;) is placed in
+<var>name</var> and <code>OPTARG</code> is set to the option character found.

+
+<p>For historical reasons, the <small>POSIX</small> standard has classified
+several builtin commands as <em>special</em>.
+When Bash is executing in <small>POSIX</small> mode, the special builtins
+differ from other builtin commands in three respects:
+</p>
+<ol>
+<li> Special builtins are found before shell functions during command lookup.
+
+</li><li> If a special builtin returns an error status, a non-interactive shell exits.
+
+</li><li> Assignment statements preceding the command stay in effect in the shell
+environment after the command completes.
+</li></ol>
+
+<p>When Bash is not executing in <small>POSIX</small> mode, these builtins behave no
+differently than the rest of the Bash builtin commands.
+The Bash <small>POSIX</small> mode is described in <a href="#Bash-POSIX-Mode">Bash POSIX Mode</a>. 
+</p>
+<p>These are the <small>POSIX</small> special builtins:

+<span id="Bash-Startup-Files-1"></span><h3 class="section">6.2 Bash Startup Files</h3>
+<span id="index-startup-files"></span>
+
+<p>This section describes how Bash executes its startup files.
+If any of the files exist but cannot be read, Bash reports an error.
+Tildes are expanded in filenames as described above under
+Tilde Expansion (see <a href="#Tilde-Expansion">Tilde Expansion</a>).
+</p>
+<p>Interactive shells are described in <a href="#Interactive-Shells">Interactive Shells</a>.
+</p>
+<span id="Invoked-as-an-interactive-login-shell_002c-or-with-_002d_002dlogin"></span><h4 class="subsubheading">Invoked as an interactive login shell, or with <samp>--login</samp></h4>
+
+<p>When Bash is invoked as an interactive login shell, or as a
+non-interactive shell with the <samp>--login</samp> option, it first reads and
+executes commands from the file <samp>/etc/profile</samp>, if that file exists.
+After reading that file, it looks for <samp>~/.bash_profile</samp>,
+<samp>~/.bash_login</samp>, and <samp>~/.profile</samp>, in that order, and reads
+and executes commands from the first one that exists and is readable.
+The <samp>--noprofile</samp> option may be used when the shell is started to
+inhibit this behavior.
+</p>
+<p>When an interactive login shell exits,
+or a non-interactive login shell executes the <code>exit</code> builtin command,
+Bash reads and executes commands from
+the file <samp>~/.bash_logout</samp>, if it exists.
+</p>
+<span id="Invoked-as-an-interactive-non_002dlogin-shell"></span><h4 class="subsubheading">Invoked as an interactive non-login shell</h4>
+
+<p>When an interactive shell that is not a login shell is started, Bash
+reads and executes commands from <samp>~/.bashrc</samp>, if that file exists.
+This may be inhibited by using the <samp>--norc</samp> option.
+The <samp>--rcfile <var>file</var></samp> option will force Bash to read and
+execute commands from <var>file</var> instead of <samp>~/.bashrc</samp>.
+</p>
+<p>So, typically, your <samp>~/.bash_profile</samp> contains the line
+</p><div class="example">
+<pre class="example"><code>if [ -f ~/.bashrc ]; then . ~/.bashrc; fi</code>
+</pre></div>
+<p>after (or before) any login-specific initializations.
+</p>
+<span id="Invoked-non_002dinteractively"></span><h4 class="subsubheading">Invoked non-interactively</h4>
+
+<p>When Bash is started non-interactively, to run a shell script,
+for example, it looks for the variable <code>BASH_ENV</code> in the environment,
+expands its value if it appears there, and uses the expanded value as
+the name of a file to read and execute.  Bash behaves as if the
+following command were executed:
+</p><div class="example">
+<pre class="example"><code>if [ -n &quot;$BASH_ENV&quot; ]; then . &quot;$BASH_ENV&quot;; fi</code>
+</pre></div>
+<p>but the value of the <code>PATH</code> variable is not used to search for the
+filename.
+</p>
+<p>As noted above, if a non-interactive shell is invoked with the
+<samp>--login</samp> option, Bash attempts to read and execute commands from the
+login shell startup files. 
+</p>
+<span id="Invoked-with-name-sh"></span><h4 class="subsubheading">Invoked with name <code>sh</code></h4>
+
+<p>If Bash is invoked with the name <code>sh</code>, it tries to mimic the
+startup behavior of historical versions of <code>sh</code> as closely as
+possible, while conforming to the <small>POSIX</small> standard as well.
+</p>
+<p>When invoked as an interactive login shell, or as a non-interactive
+shell with the <samp>--login</samp> option, it first attempts to read
+and execute commands from <samp>/etc/profile</samp> and <samp>~/.profile</samp>, in
+that order.
+The <samp>--noprofile</samp> option may be used to inhibit this behavior.
+When invoked as an interactive shell with the name <code>sh</code>, Bash
+looks for the variable <code>ENV</code>, expands its value if it is defined,
+and uses the expanded value as the name of a file to read and execute.
+Since a shell invoked as <code>sh</code> does not attempt to read and execute
+commands from any other startup files, the <samp>--rcfile</samp> option has
+no effect.
+A non-interactive shell invoked with the name <code>sh</code> does not attempt
+to read any other startup files.
+</p>
+<p>When invoked as <code>sh</code>, Bash enters <small>POSIX</small> mode after
+the startup files are read.
+</p>
+<span id="Invoked-in-POSIX-mode"></span><h4 class="subsubheading">Invoked in <small>POSIX</small> mode</h4>
+
+<p>When Bash is started in <small>POSIX</small> mode, as with the
+<samp>--posix</samp> command line option, it follows the <small>POSIX</small> standard
+for startup files.
+In this mode, interactive shells expand the <code>ENV</code> variable
+and commands are read and executed from the file whose name is the
+expanded value.

+<span id="Invoked-by-remote-shell-daemon"></span><h4 class="subsubheading">Invoked by remote shell daemon</h4>
+
+<p>Bash attempts to determine when it is being run with its standard input
+connected to a network connection, as when executed by
+the historical remote shell daemon, usually <code>rshd</code>,
+or the secure shell daemon <code>sshd</code>.
+If Bash
+determines it is being run non-interactively in this fashion,
+it reads and executes commands from <samp>~/.bashrc</samp>, if that
+file exists and is readable.
+It will not do this if invoked as <code>sh</code>.
+The <samp>--norc</samp> option may be used to inhibit this behavior, and the
+<samp>--rcfile</samp> option may be used to force another file to be read, but
+neither <code>rshd</code> nor <code>sshd</code> generally invoke the shell with those
+options or allow them to be specified.

+<p>An interactive shell
+is one started without non-option arguments
+(unless <samp>-s</samp> is specified)
+and without specifying the <samp>-c</samp> option,
+whose input and error output are both
+connected to terminals (as determined by <code>isatty(3)</code>),
+or one started with the <samp>-i</samp> option.
+</p>
+<p>An interactive shell generally reads from and writes to a user&rsquo;s
+terminal.
+</p>
+<p>The <samp>-s</samp> invocation option may be used to set the positional parameters
+when an interactive shell is started.

+<p>To determine within a startup script whether or not Bash is
+running interactively,
+test the value of the &lsquo;<samp>-</samp>&rsquo; special parameter.
+It contains <code>i</code> when the shell is interactive.  For example:
+</p>
+<div class="example">
+<pre class="example">case &quot;$-&quot; in
+*i*)	echo This shell is interactive ;;
+*)	echo This shell is not interactive ;;
+esac

+
+<p>When the shell is running interactively, it changes its behavior in
+several ways.
+</p>
+<ol>
+<li> Startup files are read and executed as described in <a href="#Bash-Startup-Files">Bash Startup Files</a>.
+
+</li><li> Job Control (see <a href="#Job-Control">Job Control</a>) is enabled by default.  When job
+control is in effect, Bash ignores the keyboard-generated job control
+signals <code>SIGTTIN</code>, <code>SIGTTOU</code>, and <code>SIGTSTP</code>.
+
+</li><li> Bash expands and displays <code>PS1</code> before reading the first line
+of a command, and expands and displays <code>PS2</code> before reading the
+second and subsequent lines of a multi-line command.
+Bash expands and displays <code>PS0</code> after it reads a command but before
+executing it.
+See <a href="#Controlling-the-Prompt">Controlling the Prompt</a>, for a complete list of prompt
+string escape sequences.
+
+</li><li> Bash executes the values of the set elements of the <code>PROMPT_COMMAND</code>
+array variable as commands before printing the primary prompt, <code>$PS1</code>
+(see <a href="#Bash-Variables">Bash Variables</a>).
+
+</li><li> Readline (see <a href="#Command-Line-Editing">Command Line Editing</a>) is used to read commands from
+the user&rsquo;s terminal.
+
+</li><li> Bash inspects the value of the <code>ignoreeof</code> option to <code>set -o</code>
+instead of exiting immediately when it receives an <code>EOF</code> on its
+standard input when reading a command (see <a href="#The-Set-Builtin">The Set Builtin</a>).
+
+</li><li> Command history (see <a href="#Bash-History-Facilities">Bash History Facilities</a>)
+and history expansion (see <a href="#History-Interaction">History Expansion</a>)
+are enabled by default.
+Bash will save the command history to the file named by <code>$HISTFILE</code>
+when a shell with history enabled exits.
+
+</li><li> Alias expansion (see <a href="#Aliases">Aliases</a>) is performed by default.
+
+</li><li> In the absence of any traps, Bash ignores <code>SIGTERM</code>
+(see <a href="#Signals">Signals</a>).
+
+</li><li> In the absence of any traps, <code>SIGINT</code> is caught and handled
+(see <a href="#Signals">Signals</a>).
+<code>SIGINT</code> will interrupt some shell builtins.
+
+</li><li> An interactive login shell sends a <code>SIGHUP</code> to all jobs on exit
+if the <code>huponexit</code> shell option has been enabled (see <a href="#Signals">Signals</a>).
+
+</li><li> The <samp>-n</samp> invocation option is ignored, and &lsquo;<samp>set -n</samp>&rsquo; has
+no effect (see <a href="#The-Set-Builtin">The Set Builtin</a>).
+
+</li><li> Bash will check for mail periodically, depending on the values of the
+<code>MAIL</code>, <code>MAILPATH</code>, and <code>MAILCHECK</code> shell variables
+(see <a href="#Bash-Variables">Bash Variables</a>).
+
+</li><li> Expansion errors due to references to unbound shell variables after
+&lsquo;<samp>set -u</samp>&rsquo; has been enabled will not cause the shell to exit
+(see <a href="#The-Set-Builtin">The Set Builtin</a>).
+
+</li><li> The shell will not exit on expansion errors caused by <var>var</var> being unset
+or null in <code>${<var>var</var>:?<var>word</var>}</code> expansions
+(see <a href="#Shell-Parameter-Expansion">Shell Parameter Expansion</a>).
+
+</li><li> Redirection errors encountered by shell builtins will not cause the
+shell to exit.
+
+</li><li> When running in <small>POSIX</small> mode, a special builtin returning an error
+status will not cause the shell to exit (see <a href="#Bash-POSIX-Mode">Bash POSIX Mode</a>).
+
+</li><li> A failed <code>exec</code> will not cause the shell to exit
+(see <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>).
+
+</li><li> Parser syntax errors will not cause the shell to exit.
+
+</li><li> If the <code>cdspell</code> shell option is enabled, the shell will attempt
+simple spelling correction for directory arguments to the <code>cd</code>
+builtin (see the description of the <code>cdspell</code>
+option to the <code>shopt</code> builtin in <a href="#The-Shopt-Builtin">The Shopt Builtin</a>).
+The <code>cdspell</code> option is only effective in interactive shells.
+
+</li><li> The shell will check the value of the <code>TMOUT</code> variable and exit
+if a command is not read within the specified number of seconds after
+printing <code>$PS1</code> (see <a href="#Bash-Variables">Bash Variables</a>).

+<span id="Bash-Conditional-Expressions-1"></span><h3 class="section">6.4 Bash Conditional Expressions</h3>
+<span id="index-expressions_002c-conditional"></span>
+
+<p>Conditional expressions are used by the <code>[[</code> compound command
+(see <a href="#Conditional-Constructs">Conditional Constructs</a>)
+and the <code>test</code> and <code>[</code> builtin commands
+(see <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>).
+The <code>test</code>
+and <code>[</code> commands determine their behavior based on the number
+of arguments; see the descriptions of those commands for any other
+command-specific actions.
+</p>
+<p>Expressions may be unary or binary,
+and are formed from the following primaries.
+Unary expressions are often used to examine the status of a file.
+There are string operators and numeric comparison operators as well.
+Bash handles several filenames specially when they are used in
+expressions.
+If the operating system on which Bash is running provides these
+special files, Bash will use them; otherwise it will emulate them
+internally with this behavior:
+If the <var>file</var> argument to one of the primaries is of the form
+<samp>/dev/fd/<var>N</var></samp>, then file descriptor <var>N</var> is checked.
+If the <var>file</var> argument to one of the primaries is one of
+<samp>/dev/stdin</samp>, <samp>/dev/stdout</samp>, or <samp>/dev/stderr</samp>, file
+descriptor 0, 1, or 2, respectively, is checked.
+</p>
+<p>When used with <code>[[</code>, the &lsquo;<samp>&lt;</samp>&rsquo; and &lsquo;<samp>&gt;</samp>&rsquo; operators sort
+lexicographically using the current locale.
+The <code>test</code> command uses ASCII ordering.
+</p>
+<p>Unless otherwise specified, primaries that operate on files follow symbolic
+links and operate on the target of the link, rather than the link itself.

+<p>Shell variables are allowed as operands; parameter expansion is
+performed before the expression is evaluated. 
+Within an expression, shell variables may also be referenced by name
+without using the parameter expansion syntax.
+A shell variable that is null or unset evaluates to 0 when referenced
+by name without using the parameter expansion syntax.
+The value of a variable is evaluated as an arithmetic expression
+when it is referenced, or when a variable which has been given the  
+<code>integer</code> attribute using &lsquo;<samp>declare -i</samp>&rsquo; is assigned a value.
+A null value evaluates to 0.
+A shell variable need not have its <code>integer</code> attribute turned on
+to be used in an expression.
+</p>
+<p>Integer constants follow the C language definition, without suffixes or
+character constants.
+Constants with a leading 0 are interpreted as octal numbers.
+A leading &lsquo;<samp>0x</samp>&rsquo; or &lsquo;<samp>0X</samp>&rsquo; denotes hexadecimal.  Otherwise,
+numbers take the form [<var>base</var><code>#</code>]<var>n</var>, where the optional <var>base</var>
+is a decimal number between 2 and 64 representing the arithmetic
+base, and <var>n</var> is a number in that base.
+If <var>base</var><code>#</code> is omitted, then base 10 is used.
+When specifying <var>n</var>,
+if a non-digit is required,
+the digits greater than 9 are represented by the lowercase letters,
+the uppercase letters, &lsquo;<samp>@</samp>&rsquo;, and &lsquo;<samp>_</samp>&rsquo;, in that order.
+If <var>base</var> is less than or equal to 36, lowercase and uppercase
+letters may be used interchangeably to represent numbers between 10
+and 35.
+</p>
+<p>Operators are evaluated in order of precedence.  Sub-expressions in

+<span id="index-alias-expansion"></span>
+
+<p><em>Aliases</em> allow a string to be substituted for a word when it is used
+as the first word of a simple command.
+The shell maintains a list of aliases that may be set and unset with
+the <code>alias</code> and <code>unalias</code> builtin commands.
+</p>
+<p>The first word of each simple command, if unquoted, is checked to see
+if it has an alias.
+If so, that word is replaced by the text of the alias.
+The characters &lsquo;<samp>/</samp>&rsquo;, &lsquo;<samp>$</samp>&rsquo;, &lsquo;<samp>`</samp>&rsquo;, &lsquo;<samp>=</samp>&rsquo; and any of the
+shell metacharacters or quoting characters listed above may not appear
+in an alias name.
+The replacement text may contain any valid
+shell input, including shell metacharacters.
+The first word of the replacement text is tested for
+aliases, but a word that is identical to an alias being expanded
+is not expanded a second time.
+This means that one may alias <code>ls</code> to <code>&quot;ls -F&quot;</code>,
+for instance, and Bash does not try to recursively expand the
+replacement text.
+If the last character of the alias value is a
+<code>blank</code>, then the next command word following the
+alias is also checked for alias expansion.
+</p>
+<p>Aliases are created and listed with the <code>alias</code>
+command, and removed with the <code>unalias</code> command.
+</p>
+<p>There is no mechanism for using arguments in the replacement text,
+as in <code>csh</code>.
+If arguments are needed, use a shell function
+(see <a href="#Shell-Functions">Shell Functions</a>).
+</p>
+<p>Aliases are not expanded when the shell is not interactive,
+unless the <code>expand_aliases</code> shell option is set using
+<code>shopt</code> (see <a href="#The-Shopt-Builtin">The Shopt Builtin</a>).
+</p>
+<p>The rules concerning the definition and use of aliases are
+somewhat confusing. Bash
+always reads at least one complete line of input,
+and all lines that make up a compound command,
+before executing any of the commands on that line or the compound command.
+Aliases are expanded when a
+command is read, not when it is executed.  Therefore, an
+alias definition appearing on the same line as another
+command does not take effect until the next line of input is read.
+The commands following the alias definition
+on that line are not affected by the new alias.
+This behavior is also an issue when functions are executed.
+Aliases are expanded when a function definition is read,
+not when the function is executed, because a function definition
+is itself a command.  As a consequence, aliases
+defined in a function are not available until after that
+function is executed.  To be safe, always put
+alias definitions on a separate line, and do not use <code>alias</code>
+in compound commands.
+</p>
+<p>For almost every purpose, shell functions are preferred over aliases.

+</div>
+<span id="Arrays-1"></span><h3 class="section">6.7 Arrays</h3>
+<span id="index-arrays"></span>
+
+<p>Bash provides one-dimensional indexed and associative array variables.
+Any variable may be used as an indexed array;
+the <code>declare</code> builtin will explicitly declare an array.
+There is no maximum
+limit on the size of an array, nor any requirement that members
+be indexed or assigned contiguously.
+Indexed arrays are referenced using integers (including arithmetic
+expressions (see <a href="#Shell-Arithmetic">Shell Arithmetic</a>)) and are zero-based;
+associative arrays use arbitrary strings.
+Unless otherwise noted, indexed array indices must be non-negative integers.
+</p>
+<p>An indexed array is created automatically if any variable is assigned to
+using the syntax
+</p><div class="example">
+<pre class="example"><var>name</var>[<var>subscript</var>]=<var>value</var>
+</pre></div>
+
+<p>The <var>subscript</var>
+is treated as an arithmetic expression that must evaluate to a number.
+To explicitly declare an array, use
+</p><div class="example">
+<pre class="example">declare -a <var>name</var>
+</pre></div>
+<p>The syntax
+</p><div class="example">
+<pre class="example">declare -a <var>name</var>[<var>subscript</var>]
+</pre></div>
+<p>is also accepted; the <var>subscript</var> is ignored.
+</p>
+<p>Associative arrays are created using
+</p><div class="example">
+<pre class="example">declare -A <var>name</var>
+</pre></div>
+
+<p>Attributes may be
+specified for an array variable using the <code>declare</code> and
+<code>readonly</code> builtins.  Each attribute applies to all members of
+an array.
+</p>
+<p>Arrays are assigned to using compound assignments of the form
+</p><div class="example">
+<pre class="example"><var>name</var>=(<var>value1</var> <var>value2</var> &hellip; )
+</pre></div>
+<p>where each
+<var>value</var> may be of the form <code>[<var>subscript</var>]=</code><var>string</var>.
+Indexed array assignments do not require anything but <var>string</var>.
+When assigning to indexed arrays, if
+the optional subscript is supplied, that index is assigned to;
+otherwise the index of the element assigned is the last index assigned
+to by the statement plus one.  Indexing starts at zero.
+</p>
+<p>Each <var>value</var> in the list undergoes all the shell expansions
+described above (see <a href="#Shell-Expansions">Shell Expansions</a>).
+</p>
+<p>When assigning to an associative array, the words in a compound assignment
+may be either assignment statements, for which the subscript is required,
+or a list of words that is interpreted as a sequence of alternating keys
+and values:
+<var>name</var>=(<var>key1</var> <var>value1</var> <var>key2</var> <var>value2</var> &hellip; ).
+These are treated identically to
+<var>name</var>=( [<var>key1</var>]=<var>value1</var> [<var>key2</var>]=<var>value2</var> &hellip; ).
+The first word in the list determines how the remaining words
+are interpreted; all assignments in a list must be of the same type.
+When using key/value pairs, the keys may not be missing or empty;
+a final missing value is treated like the empty string.
+</p>
+<p>This syntax is also accepted by the <code>declare</code>
+builtin.  Individual array elements may be assigned to using the
+<code><var>name</var>[<var>subscript</var>]=<var>value</var></code> syntax introduced above.
+</p>
+<p>When assigning to an indexed array, if <var>name</var>
+is subscripted by a negative number, that number is
+interpreted as relative to one greater than the maximum index of
+<var>name</var>, so negative indices count back from the end of the
+array, and an index of -1 references the last element.
+</p>
+<p>The &lsquo;<samp>+=</samp>&rsquo; operator will append to an array variable when assigning
+using the compound assignment syntax; see <a href="#Shell-Parameters">Shell Parameters</a> above.
+</p>
+<p>Any element of an array may be referenced using
+<code>${<var>name</var>[<var>subscript</var>]}</code>.
+The braces are required to avoid
+conflicts with the shell&rsquo;s filename expansion operators.  If the
+<var>subscript</var> is &lsquo;<samp>@</samp>&rsquo; or &lsquo;<samp>*</samp>&rsquo;, the word expands to all members
+of the array <var>name</var>.  These subscripts differ only when the word
+appears within double quotes.
+If the word is double-quoted,
+<code>${<var>name</var>[*]}</code> expands to a single word with
+the value of each array member separated by the first character of the
+<code>IFS</code> variable, and <code>${<var>name</var>[@]}</code> expands each element of
+<var>name</var> to a separate word.  When there are no array members,
+<code>${<var>name</var>[@]}</code> expands to nothing.
+If the double-quoted expansion occurs within a word, the expansion of
+the first parameter is joined with the beginning part of the original
+word, and the expansion of the last parameter is joined with the last
+part of the original word.
+This is analogous to the
+expansion of the special parameters &lsquo;<samp>@</samp>&rsquo; and &lsquo;<samp>*</samp>&rsquo;. 
+<code>${#<var>name</var>[<var>subscript</var>]}</code> expands to the length of
+<code>${<var>name</var>[<var>subscript</var>]}</code>.
+If <var>subscript</var> is &lsquo;<samp>@</samp>&rsquo; or
+&lsquo;<samp>*</samp>&rsquo;, the expansion is the number of elements in the array. 
+If the <var>subscript</var>
+used to reference an element of an indexed array
+evaluates to a number less than zero, it is
+interpreted as relative to one greater than the maximum index of the array,
+so negative indices count back from the end of the array,
+and an index of -1 refers to the last element.
+</p>
+<p>Referencing an array variable without a subscript is equivalent to
+referencing with a subscript of 0.
+Any reference to a variable using a valid subscript is legal, and
+<code>bash</code> will create an array if necessary.
+</p>
+<p>An array variable is considered set if a subscript has been assigned a
+value.  The null string is a valid value.
+</p>
+<p>It is possible to obtain the keys (indices) of an array as well as the values.
+${!<var>name</var>[@]} and ${!<var>name</var>[*]} expand to the indices
+assigned in array variable <var>name</var>.
+The treatment when in double quotes is similar to the expansion of the
+special parameters &lsquo;<samp>@</samp>&rsquo; and &lsquo;<samp>*</samp>&rsquo; within double quotes.
+</p>
+<p>The <code>unset</code> builtin is used to destroy arrays.
+<code>unset <var>name</var>[<var>subscript</var>]</code>
+destroys the array element at index <var>subscript</var>.
+Negative subscripts to indexed arrays are interpreted as described above.
+Unsetting the last element of an array variable does not unset the variable.
+<code>unset <var>name</var></code>, where <var>name</var> is an array, removes the
+entire array.
+<code>unset <var>name</var>[<var>subscript</var>]</code> behaves differently
+depending on the array type when given a
+subscript of &lsquo;<samp>*</samp>&rsquo; or &lsquo;<samp>@</samp>&rsquo;.
+When <var>name</var> is an associative array, it removes the element with key
+&lsquo;<samp>*</samp>&rsquo; or &lsquo;<samp>@</samp>&rsquo;.
+If <var>name</var> is an indexed array, <code>unset</code> removes all of the elements,
+but does not remove the array itself.
+</p>
+<p>When using a variable name with a subscript as an argument to a command,
+such as with <code>unset</code>, without using the word expansion syntax
+described above, the argument is subject to the shell&rsquo;s filename expansion.
+If filename expansion is not desired, the argument should be quoted.
+</p>
+<p>The <code>declare</code>, <code>local</code>, and <code>readonly</code>
+builtins each accept a <samp>-a</samp> option to specify an indexed
+array and a <samp>-A</samp> option to specify an associative array.
+If both options are supplied, <samp>-A</samp> takes precedence.
+The <code>read</code> builtin accepts a <samp>-a</samp>
+option to assign a list of words read from the standard input
+to an array, and can read values from the standard input into
+individual array elements.  The <code>set</code> and <code>declare</code>
+builtins display array values in a way that allows them to be
+reused as input.

+
+<p>If Bash is started with the name <code>rbash</code>, or the
+<samp>--restricted</samp>
+or
+<samp>-r</samp>
+option is supplied at invocation, the shell becomes restricted.
+A restricted shell is used to
+set up an environment more controlled than the standard shell.
+A restricted shell behaves identically to <code>bash</code>
+with the exception that the following are disallowed or not performed:
+</p>
+<ul>
+<li> Changing directories with the <code>cd</code> builtin.
+</li><li> Setting or unsetting the values of the <code>SHELL</code>, <code>PATH</code>,
+<code>HISTFILE</code>,
+<code>ENV</code>, or <code>BASH_ENV</code> variables.
+</li><li> Specifying command names containing slashes.
+</li><li> Specifying a filename containing a slash as an argument to the <code>.</code>
+builtin command.
+</li><li> Specifying a filename containing a slash as an argument to the <code>history</code>
+builtin command.
+</li><li> Specifying a filename containing a slash as an argument to the <samp>-p</samp>
+option to the <code>hash</code> builtin command.
+</li><li> Importing function definitions from the shell environment at startup.
+</li><li> Parsing the value of <code>SHELLOPTS</code> from the shell environment at startup.
+</li><li> Redirecting output using the &lsquo;<samp>&gt;</samp>&rsquo;, &lsquo;<samp>&gt;|</samp>&rsquo;, &lsquo;<samp>&lt;&gt;</samp>&rsquo;, &lsquo;<samp>&gt;&amp;</samp>&rsquo;,
+&lsquo;<samp>&amp;&gt;</samp>&rsquo;, and &lsquo;<samp>&gt;&gt;</samp>&rsquo; redirection operators.
+</li><li> Using the <code>exec</code> builtin to replace the shell with another command.
+</li><li> Adding or deleting builtin commands with the
+<samp>-f</samp> and <samp>-d</samp> options to the <code>enable</code> builtin.
+</li><li> Using the <code>enable</code> builtin command to enable disabled shell builtins.
+</li><li> Specifying the <samp>-p</samp> option to the <code>command</code> builtin.
+</li><li> Turning off restricted mode with &lsquo;<samp>set +r</samp>&rsquo; or &lsquo;<samp>shopt -u restricted_shell</samp>&rsquo;.
+</li></ul>
+
+<p>These restrictions are enforced after any startup files are read.
+</p>
+<p>When a command that is found to be a shell script is executed
+(see <a href="#Shell-Scripts">Shell Scripts</a>), <code>rbash</code> turns off any restrictions in
+the shell spawned to execute the script.
+</p>
+<p>The restricted shell mode is only one component of a useful restricted
+environment. It should be accompanied by setting <code>PATH</code> to a value
+that allows execution of only a few verified commands (commands that
+allow shell escapes are particularly vulnerable), changing the current
+directory to a non-writable directory other than <code>$HOME</code> after login,
+not allowing the restricted shell to execute shell scripts, and cleaning
+the environment of variables that cause some commands to modify their
+behavior (e.g., <code>VISUAL</code> or <code>PAGER</code>).
+</p>
+<p>Modern systems provide more secure ways to implement a restricted environment,
+such as <code>jails</code>, <code>zones</code>, or <code>containers</code>.

+<span id="Bash-POSIX-Mode-1"></span><h3 class="section">6.11 Bash POSIX Mode</h3>
+<span id="index-POSIX-Mode"></span>
+
+<p>Starting Bash with the <samp>--posix</samp> command-line option or executing
+&lsquo;<samp>set -o posix</samp>&rsquo; while Bash is running will cause Bash to conform more
+closely to the <small>POSIX</small> standard by changing the behavior to
+match that specified by <small>POSIX</small> in areas where the Bash default differs.
+</p>
+<p>When invoked as <code>sh</code>, Bash enters <small>POSIX</small> mode after reading the
+startup files.
+</p>
+<p>The following list is what&rsquo;s changed when &lsquo;<small>POSIX</small> mode&rsquo; is in effect:
+</p>
+<ol>
+<li> Bash ensures that the <code>POSIXLY_CORRECT</code> variable is set.
+
+</li><li> When a command in the hash table no longer exists, Bash will re-search
+<code>$PATH</code> to find the new location.  This is also available with
+&lsquo;<samp>shopt -s checkhash</samp>&rsquo;.
+
+</li><li> Bash will not insert a command without the execute bit set into the
+command hash table, even if it returns it as a (last-ditch) result
+from a <code>$PATH</code> search.
+
+</li><li> The message printed by the job control code and builtins when a job
+exits with a non-zero status is &lsquo;Done(status)&rsquo;.
+
+</li><li> The message printed by the job control code and builtins when a job
+is stopped is &lsquo;Stopped(<var>signame</var>)&rsquo;, where <var>signame</var> is, for
+example, <code>SIGTSTP</code>.
+
+</li><li> Alias expansion is always enabled, even in non-interactive shells.
+
+</li><li> Reserved words appearing in a context where reserved words are recognized
+do not undergo alias expansion.
+
+</li><li> Alias expansion is performed when initially parsing a command substitution.
+The default mode generally defers it, when enabled, until the command
+substitution is executed. This means that command substitution will not
+expand aliases that are defined after the command substitution is initially
+parsed (e.g., as part of a function definition).
+
+</li><li> The <small>POSIX</small> <code>PS1</code> and <code>PS2</code> expansions of &lsquo;<samp>!</samp>&rsquo; to
+the history number and &lsquo;<samp>!!</samp>&rsquo; to &lsquo;<samp>!</samp>&rsquo; are enabled,
+and parameter expansion is performed on the values of <code>PS1</code> and
+<code>PS2</code> regardless of the setting of the <code>promptvars</code> option.
+
+</li><li> The <small>POSIX</small> startup files are executed (<code>$ENV</code>) rather than
+the normal Bash files.
+
+</li><li> Tilde expansion is only performed on assignments preceding a command
+name, rather than on all assignment statements on the line.
+
+</li><li> The default history file is <samp>~/.sh_history</samp> (this is the
+default value of <code>$HISTFILE</code>).
+
+</li><li> Redirection operators do not perform filename expansion on the word
+in the redirection unless the shell is interactive.
+
+</li><li> Redirection operators do not perform word splitting on the word in the
+redirection.
+
+</li><li> Function names must be valid shell <code>name</code>s.  That is, they may not
+contain characters other than letters, digits, and underscores, and
+may not start with a digit.  Declaring a function with an invalid name
+causes a fatal syntax error in non-interactive shells.
+
+</li><li> Function names may not be the same as one of the <small>POSIX</small> special
+builtins.
+
+</li><li> <small>POSIX</small> special builtins are found before shell functions
+during command lookup.
+
+</li><li> When printing shell function definitions (e.g., by <code>type</code>), Bash does
+not print the <code>function</code> keyword.
+
+</li><li> Literal tildes that appear as the first character in elements of
+the <code>PATH</code> variable are not expanded as described above
+under <a href="#Tilde-Expansion">Tilde Expansion</a>.
+
+</li><li> The <code>time</code> reserved word may be used by itself as a command.  When
+used in this way, it displays timing statistics for the shell and its
+completed children.  The <code>TIMEFORMAT</code> variable controls the format
+of the timing information.
+
+</li><li> When parsing and expanding a ${&hellip;} expansion that appears within
+double quotes, single quotes are no longer special and cannot be used to
+quote a closing brace or other special character, unless the operator is
+one of those defined to perform pattern removal.  In this case, they do
+not have to appear as matched pairs.
+
+</li><li> The parser does not recognize <code>time</code> as a reserved word if the next
+token begins with a &lsquo;<samp>-</samp>&rsquo;.
+
+
+</li><li> The &lsquo;<samp>!</samp>&rsquo; character does not introduce history expansion within a
+double-quoted string, even if the <code>histexpand</code> option is enabled.
+
+</li><li> If a <small>POSIX</small> special builtin returns an error status, a
+non-interactive shell exits.  The fatal errors are those listed in
+the <small>POSIX</small> standard, and include things like passing incorrect options,
+redirection errors, variable assignment errors for assignments preceding
+the command name, and so on.
+
+</li><li> A non-interactive shell exits with an error status if a variable
+assignment error occurs when no command name follows the assignment
+statements.
+A variable assignment error occurs, for example, when trying to assign
+a value to a readonly variable.
+
+</li><li> A non-interactive shell exits with an error status if a variable
+assignment error occurs in an assignment statement preceding a special
+builtin, but not with any other simple command. For any other simple
+command, the shell aborts execution of that command, and execution continues
+at the top level (&quot;the shell shall not perform any further processing of the
+command in which the error occurred&quot;).
+
+</li><li> A non-interactive shell exits with an error status if the iteration
+variable in a <code>for</code> statement or the selection variable in a
+<code>select</code> statement is a readonly variable.
+
+</li><li> Non-interactive shells exit if <var>filename</var> in <code>.</code> <var>filename</var>
+is not found.
+
+</li><li> Non-interactive shells exit if a syntax error in an arithmetic expansion
+results in an invalid expression.
+
+</li><li> Non-interactive shells exit if a parameter expansion error occurs.
+
+</li><li> Non-interactive shells exit if there is a syntax error in a script read
+with the <code>.</code> or <code>source</code> builtins, or in a string processed by
+the <code>eval</code> builtin.
+
+</li><li> While variable indirection is available, it may not be applied to the
+&lsquo;<samp>#</samp>&rsquo; and &lsquo;<samp>?</samp>&rsquo; special parameters.
+
+</li><li> Expanding the &lsquo;<samp>*</samp>&rsquo; special parameter in a pattern context where the
+expansion is double-quoted does not treat the <code>$*</code> as if it were
+double-quoted.
+
+</li><li> Assignment statements preceding <small>POSIX</small> special builtins
+persist in the shell environment after the builtin completes.
+
+</li><li> The <code>command</code> builtin does not prevent builtins that take assignment
+statements as arguments from expanding them as assignment statements;
+when not in <small>POSIX</small> mode, assignment builtins lose their assignment
+statement expansion properties when preceded by <code>command</code>.
+
+</li><li> The <code>bg</code> builtin uses the required format to describe each job placed
+in the background, which does not include an indication of whether the job
+is the current or previous job.
+
+</li><li> The output of &lsquo;<samp>kill -l</samp>&rsquo; prints all the signal names on a single line,
+separated by spaces, without the &lsquo;<samp>SIG</samp>&rsquo; prefix.
+
+</li><li> The <code>kill</code> builtin does not accept signal names with a &lsquo;<samp>SIG</samp>&rsquo;
+prefix.
+
+</li><li> The <code>export</code> and <code>readonly</code> builtin commands display their
+output in the format required by <small>POSIX</small>.
+
+</li><li> The <code>trap</code> builtin displays signal names without the leading
+<code>SIG</code>.
+
+</li><li> The <code>trap</code> builtin doesn&rsquo;t check the first argument for a possible
+signal specification and revert the signal handling to the original
+disposition if it is, unless that argument consists solely of digits and
+is a valid signal number.  If users want to reset the handler for a given
+signal to the original disposition, they should use &lsquo;<samp>-</samp>&rsquo; as the
+first argument.
+
+</li><li> <code>trap -p</code> displays signals whose dispositions are set to SIG_DFL and
+those that were ignored when the shell started.
+
+</li><li> The <code>.</code> and <code>source</code> builtins do not search the current directory
+for the filename argument if it is not found by searching <code>PATH</code>.
+
+</li><li> Enabling <small>POSIX</small> mode has the effect of setting the
+<code>inherit_errexit</code> option, so
+subshells spawned to execute command substitutions inherit the value of
+the <samp>-e</samp> option from the parent shell.
+When the <code>inherit_errexit</code> option is not enabled,
+Bash clears the <samp>-e</samp> option in such subshells.
+
+</li><li> Enabling <small>POSIX</small> mode has the effect of setting the
+<code>shift_verbose</code> option, so numeric arguments to <code>shift</code>
+that exceed the number of positional parameters will result in an
+error message.
+
+</li><li> When the <code>alias</code> builtin displays alias definitions, it does not
+display them with a leading &lsquo;<samp>alias </samp>&rsquo; unless the <samp>-p</samp> option
+is supplied.
+
+</li><li> When the <code>set</code> builtin is invoked without options, it does not display
+shell function names and definitions.
+
+</li><li> When the <code>set</code> builtin is invoked without options, it displays
+variable values without quotes, unless they contain shell metacharacters,
+even if the result contains nonprinting characters.
+
+</li><li> When the <code>cd</code> builtin is invoked in logical mode, and the pathname
+constructed from <code>$PWD</code> and the directory name supplied as an argument
+does not refer to an existing directory, <code>cd</code> will fail instead of
+falling back to physical mode.
+
+</li><li> When the <code>cd</code> builtin cannot change a directory because the
+length of the pathname 
+constructed from <code>$PWD</code> and the directory name supplied as an argument
+exceeds <code>PATH_MAX</code> when all symbolic links are expanded, <code>cd</code> will
+fail instead of attempting to use only the supplied directory name.
+
+</li><li> The <code>pwd</code> builtin verifies that the value it prints is the same as the
+current directory, even if it is not asked to check the file system with the
+<samp>-P</samp> option.
+
+</li><li> When listing the history, the <code>fc</code> builtin does not include an
+indication of whether or not a history entry has been modified.
+
+</li><li> The default editor used by <code>fc</code> is <code>ed</code>.
+
+</li><li> The <code>type</code> and <code>command</code> builtins will not report a non-executable
+file as having been found, though the shell will attempt to execute such a
+file if it is the only so-named file found in <code>$PATH</code>.
+
+</li><li> The <code>vi</code> editing mode will invoke the <code>vi</code> editor directly when
+the &lsquo;<samp>v</samp>&rsquo; command is run, instead of checking <code>$VISUAL</code> and
+<code>$EDITOR</code>.
+
+</li><li> When the <code>xpg_echo</code> option is enabled, Bash does not attempt to interpret
+any arguments to <code>echo</code> as options.  Each argument is displayed, after
+escape characters are converted.
+
+</li><li> The <code>ulimit</code> builtin uses a block size of 512 bytes for the <samp>-c</samp>
+and <samp>-f</samp> options.
+
+</li><li> The arrival of <code>SIGCHLD</code>  when a trap is set on <code>SIGCHLD</code> does
+not interrupt the <code>wait</code> builtin and cause it to return immediately.
+The trap command is run once for each child that exits.
+
+</li><li> The <code>read</code> builtin may be interrupted by a signal for which a trap
+has been set.
+If Bash receives a trapped signal while executing <code>read</code>, the trap
+handler executes and <code>read</code> returns an exit status greater than 128.
+
+</li><li> The <code>printf</code> builtin uses <code>double</code> (via <code>strtod</code>) to convert
+arguments corresponding to floating point conversion specifiers, instead of
+<code>long double</code> if it&rsquo;s available. The &lsquo;<samp>L</samp>&rsquo; length modifier forces
+<code>printf</code> to use <code>long double</code> if it&rsquo;s available.
+
+</li><li> Bash removes an exited background process&rsquo;s status from the list of such
+statuses after the <code>wait</code> builtin is used to obtain it.
+
+</li></ol>
+
+<p>There is other <small>POSIX</small> behavior that Bash does not implement by
+default even when in <small>POSIX</small> mode.
+Specifically:
+</p>
+<ol>
+<li> The <code>fc</code> builtin checks <code>$EDITOR</code> as a program to edit history
+entries if <code>FCEDIT</code> is unset, rather than defaulting directly to
+<code>ed</code>.  <code>fc</code> uses <code>ed</code> if <code>EDITOR</code> is unset.
+
+</li><li> As noted above, Bash requires the <code>xpg_echo</code> option to be enabled for
+the <code>echo</code> builtin to be fully conformant.
+
+</li></ol>
+
+<p>Bash can be configured to be <small>POSIX</small>-conformant by default, by specifying
+the <samp>--enable-strict-posix-default</samp> to <code>configure</code> when building
+(see <a href="#Optional-Features">Optional Features</a>).

+<span id="index-Compatibility-Level"></span>
+<span id="index-Compatibility-Mode"></span>
+
+<p>Bash-4.0 introduced the concept of a <em>shell compatibility level</em>,
+specified as a set of options to the shopt builtin
+(<code>compat31</code>,
+<code>compat32</code>,
+<code>compat40</code>,
+<code>compat41</code>,
+and so on).
+There is only one current
+compatibility level &ndash; each option is mutually exclusive.
+The compatibility level is intended to allow users to select behavior
+from previous versions that is incompatible with newer versions
+while they migrate scripts to use current features and
+behavior. It&rsquo;s intended to be a temporary solution.
+</p>
+<p>This section does not mention behavior that is standard for a particular
+version (e.g., setting <code>compat32</code> means that quoting the rhs of the regexp
+matching operator quotes special regexp characters in the word, which is
+default behavior in bash-3.2 and subsequent versions). 
+</p>
+<p>If a user enables, say, <code>compat32</code>, it may affect the behavior of other
+compatibility levels up to and including the current compatibility level.
+The idea is that each compatibility level controls behavior that changed
+in that version of Bash,
+but that behavior may have been present in earlier versions.
+For instance, the change to use locale-based comparisons with the <code>[[</code>
+command came in bash-4.1, and earlier versions used ASCII-based comparisons,
+so enabling <code>compat32</code> will enable ASCII-based comparisons as well.
+That granularity may not be sufficient for
+all uses, and as a result users should employ compatibility levels carefully.
+Read the documentation for a particular feature to find out the
+current behavior.
+</p>
+<p>Bash-4.3 introduced a new shell variable: <code>BASH_COMPAT</code>.
+The value assigned
+to this variable (a decimal version number like 4.2, or an integer
+corresponding to the <code>compat</code><var>NN</var> option, like 42) determines the
+compatibility level.
+</p>
+<p>Starting with bash-4.4, Bash has begun deprecating older compatibility
+levels.
+Eventually, the options will be removed in favor of <code>BASH_COMPAT</code>.
+</p>
+<p>Bash-5.0 is the final version for which there will be an individual shopt
+option for the previous version. Users should use <code>BASH_COMPAT</code>
+on bash-5.0 and later versions.
+</p>
+<p>The following table describes the behavior changes controlled by each
+compatibility level setting.
+The <code>compat</code><var>NN</var> tag is used as shorthand for setting the
+compatibility level
+to <var>NN</var> using one of the following mechanisms.
+For versions prior to bash-5.0, the compatibility level may be set using
+the corresponding <code>compat</code><var>NN</var> shopt option.
+For bash-4.3 and later versions, the <code>BASH_COMPAT</code> variable is preferred,
+and it is required for bash-5.1 and later versions.

+<span id="index-job-control-1"></span>
+<span id="index-foreground"></span>
+<span id="index-background"></span>
+<span id="index-suspending-jobs"></span>
+
+<p>Job control
+refers to the ability to selectively stop (suspend)
+the execution of processes and continue (resume)
+their execution at a later point.  A user typically employs
+this facility via an interactive interface supplied jointly
+by the operating system kernel&rsquo;s terminal driver and Bash.
+</p>
+<p>The shell associates a <var>job</var> with each pipeline.  It keeps a
+table of currently executing jobs, which may be listed with the
+<code>jobs</code> command.  When Bash starts a job
+asynchronously, it prints a line that looks
+like:
+</p><div class="example">
+<pre class="example">[1] 25647
+</pre></div>
+<p>indicating that this job is job number 1 and that the process <small>ID</small>
+of the last process in the pipeline associated with this job is
+25647.  All of the processes in a single pipeline are members of
+the same job.  Bash uses the <var>job</var> abstraction as the
+basis for job control. 
+</p>
+<p>To facilitate the implementation of the user interface to job
+control, the operating system maintains the notion of a current terminal
+process group <small>ID</small>.  Members of this process group (processes whose
+process group <small>ID</small> is equal to the current terminal process group
+<small>ID</small>) receive keyboard-generated signals such as <code>SIGINT</code>. 
+These processes are said to be in the foreground.  Background
+processes are those whose process group <small>ID</small> differs from the
+terminal&rsquo;s; such processes are immune to keyboard-generated
+signals.  Only foreground processes are allowed to read from or, if
+the user so specifies with <code>stty tostop</code>, write to the terminal.
+Background processes which attempt to
+read from (write to when <code>stty tostop</code> is in effect) the
+terminal are sent a <code>SIGTTIN</code> (<code>SIGTTOU</code>)
+signal by the kernel&rsquo;s terminal driver,
+which, unless caught, suspends the process. 
+</p>
+<p>If the operating system on which Bash is running supports
+job control, Bash contains facilities to use it.  Typing the
+<em>suspend</em> character (typically &lsquo;<samp>^Z</samp>&rsquo;, Control-Z) while a
+process is running causes that process to be stopped and returns
+control to Bash.  Typing the <em>delayed suspend</em> character
+(typically &lsquo;<samp>^Y</samp>&rsquo;, Control-Y) causes the process to be stopped
+when it attempts to read input from the terminal, and control to
+be returned to Bash.  The user then manipulates the state of
+this job, using the <code>bg</code> command to continue it in the
+background, the <code>fg</code> command to continue it in the
+foreground, or the <code>kill</code> command to kill it.  A &lsquo;<samp>^Z</samp>&rsquo;
+takes effect immediately, and has the additional side effect of
+causing pending output and typeahead to be discarded. 
+</p>
+<p>There are a number of ways to refer to a job in the shell.  The
+character &lsquo;<samp>%</samp>&rsquo; introduces a job specification (<em>jobspec</em>).
+</p>
+<p>Job number <code>n</code> may be referred to as &lsquo;<samp>%n</samp>&rsquo;.
+The symbols &lsquo;<samp>%%</samp>&rsquo; and  &lsquo;<samp>%+</samp>&rsquo; refer to the shell&rsquo;s notion of the
+current job, which is the last job stopped while it was in the foreground
+or started in the background.
+A single &lsquo;<samp>%</samp>&rsquo; (with no accompanying job specification) also refers
+to the current job.
+The previous job may be referenced using &lsquo;<samp>%-</samp>&rsquo;.
+If there is only a single job, &lsquo;<samp>%+</samp>&rsquo; and &lsquo;<samp>%-</samp>&rsquo; can both be used
+to refer to that job.
+In output pertaining to jobs (e.g., the output of the <code>jobs</code>
+command), the current job is always flagged with a &lsquo;<samp>+</samp>&rsquo;, and the
+previous job with a &lsquo;<samp>-</samp>&rsquo;. 
+</p>
+<p>A job may also be referred to
+using a prefix of the name used to start it, or using a substring
+that appears in its command line.  For example, &lsquo;<samp>%ce</samp>&rsquo; refers
+to a stopped job whose command name begins with &lsquo;<samp>ce</samp>&rsquo;.
+Using &lsquo;<samp>%?ce</samp>&rsquo;, on the
+other hand, refers to any job containing the string &lsquo;<samp>ce</samp>&rsquo; in
+its command line.  If the prefix or substring matches more than one job,
+Bash reports an error.
+</p>
+<p>Simply naming a job can be used to bring it into the foreground:
+&lsquo;<samp>%1</samp>&rsquo; is a synonym for &lsquo;<samp>fg %1</samp>&rsquo;, bringing job 1 from the
+background into the foreground.  Similarly, &lsquo;<samp>%1 &amp;</samp>&rsquo; resumes
+job 1 in the background, equivalent to &lsquo;<samp>bg %1</samp>&rsquo;
+</p>
+<p>The shell learns immediately whenever a job changes state. 
+Normally, Bash waits until it is about to print a prompt
+before reporting changes in a job&rsquo;s status so as to not interrupt
+any other output.
+If the <samp>-b</samp> option to the <code>set</code> builtin is enabled,
+Bash reports such changes immediately (see <a href="#The-Set-Builtin">The Set Builtin</a>).
+Any trap on <code>SIGCHLD</code> is executed for each child process
+that exits.
+</p>
+<p>If an attempt to exit Bash is made while jobs are stopped, (or running, if
+the <code>checkjobs</code> option is enabled &ndash; see <a href="#The-Shopt-Builtin">The Shopt Builtin</a>), the
+shell prints a warning message, and if the <code>checkjobs</code> option is
+enabled, lists the jobs and their statuses.
+The <code>jobs</code> command may then be used to inspect their status.
+If a second attempt to exit is made without an intervening command,
+Bash does not print another warning, and any stopped jobs are terminated.
+</p>
+<p>When the shell is waiting for a job or process using the <code>wait</code>
+builtin, and job control is enabled, <code>wait</code> will return when the
+job changes state. The <samp>-f</samp> option causes <code>wait</code> to wait
+until the job or process terminates before returning.

+<p>This chapter describes the basic features of the <small>GNU</small>
+command line editing interface.
+Command line editing is provided by the Readline library, which is
+used by several different programs, including Bash.
+Command line editing is enabled by default when using an interactive shell,
+unless the <samp>--noediting</samp> option is supplied at shell invocation.
+Line editing is also used when using the <samp>-e</samp> option to the
+<code>read</code> builtin command (see <a href="#Bash-Builtins">Bash Builtin Commands</a>).
+By default, the line editing commands are similar to those of Emacs.
+A vi-style line editing interface is also available.
+Line editing can be enabled at any time using the <samp>-o emacs</samp> or
+<samp>-o vi</samp> options to the <code>set</code> builtin command
+(see <a href="#The-Set-Builtin">The Set Builtin</a>), or disabled using the <samp>+o emacs</samp> or

+<p>The following paragraphs describe the notation used to represent
+keystrokes.
+</p>
+<p>The text <kbd>C-k</kbd> is read as &lsquo;Control-K&rsquo; and describes the character
+produced when the <tt class="key">k</tt> key is pressed while the Control key
+is depressed.
+</p>
+<p>The text <kbd>M-k</kbd> is read as &lsquo;Meta-K&rsquo; and describes the character
+produced when the Meta key (if you have one) is depressed, and the <tt class="key">k</tt>
+key is pressed.
+The Meta key is labeled <tt class="key">ALT</tt> on many keyboards.
+On keyboards with two keys labeled <tt class="key">ALT</tt> (usually to either side of
+the space bar), the <tt class="key">ALT</tt> on the left side is generally set to
+work as a Meta key.
+The <tt class="key">ALT</tt> key on the right may also be configured to work as a
+Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+</p>
+<p>If you do not have a Meta or <tt class="key">ALT</tt> key, or another key working as
+a Meta key, the identical keystroke can be generated by typing <tt class="key">ESC</tt>
+<em>first</em>, and then typing <tt class="key">k</tt>.
+Either process is known as <em>metafying</em> the <tt class="key">k</tt> key.
+</p>
+<p>The text <kbd>M-C-k</kbd> is read as &lsquo;Meta-Control-k&rsquo; and describes the
+character produced by <em>metafying</em> <kbd>C-k</kbd>.
+</p>
+<p>In addition, several keys have their own names.  Specifically,
+<tt class="key">DEL</tt>, <tt class="key">ESC</tt>, <tt class="key">LFD</tt>, <tt class="key">SPC</tt>, <tt class="key">RET</tt>, and <tt class="key">TAB</tt> all

+(see <a href="#Readline-Init-File">Readline Init File</a>).
+If your keyboard lacks a <tt class="key">LFD</tt> key, typing <tt class="key">C-j</tt> will

+
+<p>Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled.  The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line.  Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections.  Then, when you are satisfied with
+the line, you simply press <tt class="key">RET</tt>.  You do not have to be at the
+end of the line to press <tt class="key">RET</tt>; the entire line is accepted
+regardless of the location of the cursor within the line.

+
+<p>In order to enter characters into the line, simply type them.  The typed
+character appears where the cursor was, and then the cursor moves one
+space to the right.  If you mistype a character, you can use your
+erase character to back up and delete the mistyped character.
+</p>
+<p>Sometimes you may mistype a character, and
+not notice the error until you have typed several other characters.  In
+that case, you can type <kbd>C-b</kbd> to move the cursor to the left, and then
+correct your mistake.  Afterwards, you can move the cursor to the right
+with <kbd>C-f</kbd>.
+</p>
+<p>When you add text in the middle of a line, you will notice that characters
+to the right of the cursor are &lsquo;pushed over&rsquo; to make room for the text
+that you have inserted.  Likewise, when you delete text behind the cursor,
+characters to the right of the cursor are &lsquo;pulled back&rsquo; to fill in the
+blank space created by the removal of the text.  A list of the bare
+essentials for editing the text of an input line follows.

+
+<p><em>Killing</em> text means to delete the text from the line, but to save
+it away for later use, usually by <em>yanking</em> (re-inserting)
+it back into the line.
+(&lsquo;Cut&rsquo; and &lsquo;paste&rsquo; are more recent jargon for &lsquo;kill&rsquo; and &lsquo;yank&rsquo;.)
+</p>
+<p>If the description for a command says that it &lsquo;kills&rsquo; text, then you can
+be sure that you can get the text back in a different (or the same)
+place later.
+</p>
+<p>When you use a kill command, the text is saved in a <em>kill-ring</em>.
+Any number of consecutive kills save all of the killed text together, so
+that when you yank it back, you get it all.  The kill
+ring is not line specific; the text that you killed on a previously
+typed line is available to be yanked back later, when you are typing
+another line.
+<span id="index-kill-ring"></span>
+</p>
+<p>Here is the list of commands for killing text.
+</p>
+<dl compact="compact">
+<dt><span><kbd>C-k</kbd></span></dt>

+
+<p>You can pass numeric arguments to Readline commands.  Sometimes the
+argument acts as a repeat count, other times it is the <i>sign</i> of the
+argument that is significant.  If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction.  For example, to kill text back to the
+start of the line, you might type &lsquo;<samp>M-- C-k</samp>&rsquo;.
+</p>
+<p>The general way to pass numeric arguments to a command is to type meta
+digits before the command.  If the first &lsquo;digit&rsquo; typed is a minus
+sign (&lsquo;<samp>-</samp>&rsquo;), then the sign of the argument will be negative.  Once
+you have typed one meta digit to get the argument started, you can type
+the remainder of the digits, and then the command.  For example, to give
+the <kbd>C-d</kbd> command an argument of 10, you could type &lsquo;<samp>M-1 0 C-d</samp>&rsquo;,
+which will delete the next ten characters on the input line.

+<span id="Searching-for-Commands-in-the-History"></span><h4 class="subsection">8.2.5 Searching for Commands in the History</h4>
+
+<p>Readline provides commands for searching through the command history
+(see <a href="#Bash-History-Facilities">Bash History Facilities</a>)
+for lines containing a specified string.
+There are two search modes:  <em>incremental</em> and <em>non-incremental</em>.
+</p>
+<p>Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, Readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+To search backward in the history for a particular string, type
+<kbd>C-r</kbd>.  Typing <kbd>C-s</kbd> searches forward through the history.
+The characters present in the value of the <code>isearch-terminators</code> variable
+are used to terminate an incremental search.
+If that variable has not been assigned a value, the <tt class="key">ESC</tt> and
+<kbd>C-J</kbd> characters will terminate an incremental search.
+<kbd>C-g</kbd> will abort an incremental search and restore the original line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+</p>
+<p>To find other matching entries in the history list, type <kbd>C-r</kbd> or
+<kbd>C-s</kbd> as appropriate.
+This will search backward or forward in the history for the next
+entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate
+the search and execute that command.
+For instance, a <tt class="key">RET</tt> will terminate the search and accept
+the line, thereby executing the command from the history list.
+A movement command will terminate the search, make the last line found
+the current line, and begin editing.
+</p>
+<p>Readline remembers the last incremental search string.  If two
+<kbd>C-r</kbd>s are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+</p>
+<p>Non-incremental searches read the entire search string before starting
+to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.

+
+<p>Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.
+Any user can customize programs that use Readline by putting
+commands in an <em>inputrc</em> file,
+conventionally in their home directory.
+The name of this
+file is taken from the value of the shell variable <code>INPUTRC</code>.  If
+that variable is unset, the default is <samp>~/.inputrc</samp>.  If that
+file does not exist or cannot be read, the ultimate default is
+<samp>/etc/inputrc</samp>.
+The <code>bind</code><!-- /@w --> builtin command can also be used to set Readline
+keybindings and variables.
+See <a href="#Bash-Builtins">Bash Builtin Commands</a>.
+</p>
+<p>When a program which uses the Readline library starts up, the
+init file is read, and the key bindings are set.
+</p>
+<p>In addition, the <code>C-x C-r</code> command re-reads this init file, thus
+incorporating any changes that you might have made to it.

+
+<p>Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests.  There are four parser directives used.
+</p>
+<dl compact="compact">
+<dt><span><code>$if</code></span></dt>
+<dd><p>The <code>$if</code> construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+Readline.  The text of the test, after any comparison operator,
+extends to the end of the line;
+unless otherwise noted, no characters are required to isolate it.
+</p>
+<dl compact="compact">
+<dt><span><code>mode</code></span></dt>
+<dd><p>The <code>mode=</code> form of the <code>$if</code> directive is used to test
+whether Readline is in <code>emacs</code> or <code>vi</code> mode.
+This may be used in conjunction
+with the &lsquo;<samp>set keymap</samp>&rsquo; command, for instance, to set bindings in
+the <code>emacs-standard</code> and <code>emacs-ctlx</code> keymaps only if
+Readline is starting out in <code>emacs</code> mode.
+</p>
+</dd>
+<dt><span><code>term</code></span></dt>
+<dd><p>The <code>term=</code> form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal&rsquo;s function keys.  The word on the right side of the
+&lsquo;<samp>=</samp>&rsquo; is tested against both the full name of the terminal and
+the portion of the terminal name before the first &lsquo;<samp>-</samp>&rsquo;.  This
+allows <code>sun</code> to match both <code>sun</code> and <code>sun-cmd</code>,
+for instance.
+</p>
+</dd>
+<dt><span><code>version</code></span></dt>
+<dd><p>The <code>version</code> test may be used to perform comparisons against
+specific Readline versions.
+The <code>version</code> expands to the current Readline version.
+The set of comparison operators includes
+&lsquo;<samp>=</samp>&rsquo; (and &lsquo;<samp>==</samp>&rsquo;), &lsquo;<samp>!=</samp>&rsquo;, &lsquo;<samp>&lt;=</samp>&rsquo;, &lsquo;<samp>&gt;=</samp>&rsquo;, &lsquo;<samp>&lt;</samp>&rsquo;,
+and &lsquo;<samp>&gt;</samp>&rsquo;.
+The version number supplied on the right side of the operator consists
+of a major version number, an optional decimal point, and an optional
+minor version (e.g., &lsquo;<samp>7.1</samp>&rsquo;). If the minor version is omitted, it
+is assumed to be &lsquo;<samp>0</samp>&rsquo;.
+The operator may be separated from the string <code>version</code> and
+from the version number argument by whitespace.
+The following example sets a variable if the Readline version being used
+is 7.0 or newer:
+</p><div class="example">
+<pre class="example">$if version &gt;= 7.0
+set show-mode-in-prompt on
+$endif
+</pre></div>
+
+</dd>
+<dt><span><code>application</code></span></dt>
+<dd><p>The <var>application</var> construct is used to include
+application-specific settings.  Each program using the Readline
+library sets the <var>application name</var>, and you can test for
+a particular value. 
+This could be used to bind key sequences to functions useful for
+a specific program.  For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+</p><div class="example">
+<pre class="example">$if Bash
+# Quote the current or previous word
+&quot;\C-xq&quot;: &quot;\eb\&quot;\ef\&quot;&quot;
+$endif
+</pre></div>
+
+</dd>
+<dt><span><code>variable</code></span></dt>
+<dd><p>The <var>variable</var> construct provides simple equality tests for Readline
+variables and values.
+The permitted comparison operators are &lsquo;<samp>=</samp>&rsquo;, &lsquo;<samp>==</samp>&rsquo;, and &lsquo;<samp>!=</samp>&rsquo;.
+The variable name must be separated from the comparison operator by
+whitespace; the operator may be separated from the value on the right hand
+side by whitespace.
+Both string and boolean variables may be tested. Boolean variables must be
+tested against the values <var>on</var> and <var>off</var>.
+The following example is equivalent to the <code>mode=emacs</code> test described
+above:
+</p><div class="example">
+<pre class="example">$if editing-mode == emacs
+set show-mode-in-prompt on
+$endif
+</pre></div>
+</dd>
+</dl>
+
+</dd>
+<dt><span><code>$endif</code></span></dt>
+<dd><p>This command, as seen in the previous example, terminates an
+<code>$if</code> command.
+</p>
+</dd>
+<dt><span><code>$else</code></span></dt>
+<dd><p>Commands in this branch of the <code>$if</code> directive are executed if
+the test fails.
+</p>
+</dd>
+<dt><span><code>$include</code></span></dt>
+<dd><p>This directive takes a single filename as an argument and reads commands
+and bindings from that file.
+For example, the following directive reads from <samp>/etc/inputrc</samp>:
+</p><div class="example">
+<pre class="example">$include /etc/inputrc
+</pre></div>

+<span id="Programmable-Completion-1"></span><h3 class="section">8.6 Programmable Completion</h3>
+<span id="index-programmable-completion"></span>
+
+<p>When word completion is attempted for an argument to a command for
+which a completion specification (a <var>compspec</var>) has been defined
+using the <code>complete</code> builtin (see <a href="#Programmable-Completion-Builtins">Programmable Completion Builtins</a>),
+the programmable completion facilities are invoked. 
+</p>
+<p>First, the command name is identified.
+If a compspec has been defined for that command, the
+compspec is used to generate the list of possible completions for the word.
+If the command word is the empty string (completion attempted at the
+beginning of an empty line), any compspec defined with
+the <samp>-E</samp> option to <code>complete</code> is used.
+If the command word is a full pathname, a compspec for the full
+pathname is searched for first.
+If no compspec is found for the full pathname, an attempt is made to
+find a compspec for the portion following the final slash.
+If those searches do not result in a compspec, any compspec defined with
+the <samp>-D</samp> option to <code>complete</code> is used as the default.
+If there is no default compspec, Bash attempts alias expansion
+on the command word as a final resort, and attempts to find a compspec
+for the command word from any successful expansion 
+</p>
+<p>Once a compspec has been found, it is used to generate the list of
+matching words.
+If a compspec is not found, the default Bash completion
+described above (see <a href="#Commands-For-Completion">Letting Readline Type For You</a>) is performed.
+</p>
+<p>First, the actions specified by the compspec are used.
+Only matches which are prefixed by the word being completed are
+returned.
+When the <samp>-f</samp> or <samp>-d</samp> option is used for filename or
+directory name completion, the shell variable <code>FIGNORE</code> is
+used to filter the matches.
+See <a href="#Bash-Variables">Bash Variables</a>, for a description of <code>FIGNORE</code>.
+</p>
+<p>Any completions specified by a filename expansion pattern to the
+<samp>-G</samp> option are generated next.
+The words generated by the pattern need not match the word being completed.
+The <code>GLOBIGNORE</code> shell variable is not used to filter the matches,
+but the <code>FIGNORE</code> shell variable is used.
+</p>
+<p>Next, the string specified as the argument to the <samp>-W</samp> option
+is considered.
+The string is first split using the characters in the <code>IFS</code>
+special variable as delimiters.
+Shell quoting is honored within the string, in order to provide a
+mechanism for the words to contain shell metacharacters or characters
+in the value of <code>IFS</code>.
+Each word is then expanded using
+brace expansion, tilde expansion, parameter and variable expansion,
+command substitution, and arithmetic expansion,
+as described above (see <a href="#Shell-Expansions">Shell Expansions</a>).
+The results are split using the rules described above
+(see <a href="#Word-Splitting">Word Splitting</a>).
+The results of the expansion are prefix-matched against the word being
+completed, and the matching words become the possible completions.
+</p>
+<p>After these matches have been generated, any shell function or command
+specified with the <samp>-F</samp> and <samp>-C</samp> options is invoked.
+When the command or function is invoked, the <code>COMP_LINE</code>,
+<code>COMP_POINT</code>, <code>COMP_KEY</code>, and <code>COMP_TYPE</code> variables are
+assigned values as described above (see <a href="#Bash-Variables">Bash Variables</a>).
+If a shell function is being invoked, the <code>COMP_WORDS</code> and
+<code>COMP_CWORD</code> variables are also set.
+When the function or command is invoked, the first argument ($1) is the
+name of the command whose arguments are being completed, the
+second argument ($2) is the word being completed, and the third argument
+($3) is the word preceding the word being completed on the current command
+line.
+No filtering of the generated completions against the word being completed
+is performed; the function or command has complete freedom in generating
+the matches.
+</p>
+<p>Any function specified with <samp>-F</samp> is invoked first.
+The function may use any of the shell facilities, including the
+<code>compgen</code> and <code>compopt</code> builtins described below
+(see <a href="#Programmable-Completion-Builtins">Programmable Completion Builtins</a>), to generate the matches.
+It must put the possible completions in the <code>COMPREPLY</code> array
+variable, one per array element.
+</p>
+<p>Next, any command specified with the <samp>-C</samp> option is invoked
+in an environment equivalent to command substitution.
+It should print a list of completions, one per line, to
+the standard output.
+Backslash may be used to escape a newline, if necessary.
+</p>
+<p>After all of the possible completions are generated, any filter
+specified with the <samp>-X</samp> option is applied to the list.
+The filter is a pattern as used for pathname expansion; a &lsquo;<samp>&amp;</samp>&rsquo;
+in the pattern is replaced with the text of the word being completed.
+A literal &lsquo;<samp>&amp;</samp>&rsquo; may be escaped with a backslash; the backslash
+is removed before attempting a match.
+Any completion that matches the pattern will be removed from the list.
+A leading &lsquo;<samp>!</samp>&rsquo; negates the pattern; in this case any completion
+not matching the pattern will be removed.
+If the <code>nocasematch</code> shell option
+(see the description of <code>shopt</code> in <a href="#The-Shopt-Builtin">The Shopt Builtin</a>)
+is enabled, the match is performed without regard to the case
+of alphabetic characters.
+</p>
+<p>Finally, any prefix and suffix specified with the <samp>-P</samp> and <samp>-S</samp>
+options are added to each member of the completion list, and the result is
+returned to the Readline completion code as the list of possible
+completions.
+</p>
+<p>If the previously-applied actions do not generate any matches, and the
+<samp>-o dirnames</samp> option was supplied to <code>complete</code> when the
+compspec was defined, directory name completion is attempted. 
+</p>
+<p>If the <samp>-o plusdirs</samp> option was supplied to <code>complete</code> when
+the compspec was defined, directory name completion is attempted and any
+matches are added to the results of the other actions.
+</p>
+<p>By default, if a compspec is found, whatever it generates is returned to
+the completion code as the full set of possible completions.
+The default Bash completions are not attempted, and the Readline default
+of filename completion is disabled.
+If the <samp>-o bashdefault</samp> option was supplied to <code>complete</code> when
+the compspec was defined, the default Bash completions are attempted
+if the compspec generates no matches.
+If the <samp>-o default</samp> option was supplied to <code>complete</code> when the
+compspec was defined, Readline&rsquo;s default completion will be performed
+if the compspec (and, if attempted, the default Bash completions)
+generate no matches.
+</p>
+<p>When a compspec indicates that directory name completion is desired,
+the programmable completion functions force Readline to append a slash
+to completed names which are symbolic links to directories, subject to
+the value of the <var>mark-directories</var> Readline variable, regardless
+of the setting of the <var>mark-symlinked-directories</var> Readline variable.
+</p>
+<p>There is some support for dynamically modifying completions.  This is
+most useful when used in combination with a default completion specified
+with <samp>-D</samp>.  It&rsquo;s possible for shell functions executed as completion
+handlers to indicate that completion should be retried by returning an
+exit status of 124.  If a shell function returns 124, and changes
+the compspec associated with the command on which completion is being
+attempted (supplied as the first argument when the function is executed),
+programmable completion restarts from the beginning, with an
+attempt to find a new compspec for that command.  This allows a set of
+completions to be built dynamically as completion is attempted, rather than
+being loaded all at once.
+</p>
+<p>For instance, assuming that there is a library of compspecs, each kept in a
+file corresponding to the name of the command, the following default
+completion function would load completions dynamically:
+</p>
+<div class="example">
+<pre class="example">_completion_loader()
+{
+    . &quot;/etc/bash_completion.d/$1.sh&quot; &gt;/dev/null 2&gt;&amp;1 &amp;&amp; return 124
+}
+complete -D -F _completion_loader -o bashdefault -o default

+
+<p>The most common way to obtain additional completion functionality beyond
+the default actions <code>complete</code> and <code>compgen</code> provide is to use
+a shell function and bind it to a particular command using <code>complete -F</code>.
+</p>
+<p>The following function provides completions for the <code>cd</code> builtin.
+It is a reasonably good example of what shell functions must do when
+used for completion.  This function uses the word passed as <code>$2</code>
+to determine the directory name to complete.  You can also use the
+<code>COMP_WORDS</code> array variable; the current word is indexed by the
+<code>COMP_CWORD</code> variable.
+</p>
+<p>The function relies on the <code>complete</code> and <code>compgen</code> builtins
+to do much of the work, adding only the things that the Bash <code>cd</code>
+does beyond accepting basic directory names:
+tilde expansion (see <a href="#Tilde-Expansion">Tilde Expansion</a>),
+searching directories in <var>$CDPATH</var>, which is described above
+(see <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>),
+and basic support for the <code>cdable_vars</code> shell option
+(see <a href="#The-Shopt-Builtin">The Shopt Builtin</a>).
+<code>_comp_cd</code> modifies the value of <var>IFS</var> so that it contains only
+a newline to accommodate file names containing spaces and tabs &ndash;
+<code>compgen</code> prints the possible completions it generates one per line.
+</p>
+<p>Possible completions go into the <var>COMPREPLY</var> array variable, one
+completion per array element.  The programmable completion system retrieves
+the completions from there when the function returns.
+</p>
+<div class="example">
+<pre class="example"># A completion function for the cd builtin

+

+</pre></div>
+
+<p>We install the completion function using the <samp>-F</samp> option to
+<code>complete</code>:
+</p>
+<div class="example">
+<pre class="example"># Tell readline to quote appropriate and append slashes to directories;
+# use the bash default completion for other arguments
+complete -o filenames -o nospace -o bashdefault -F _comp_cd cd
+</pre></div>
+
+<p>Since we&rsquo;d like Bash and Readline to take care of some
+of the other details for us, we use several other options to tell Bash
+and Readline what to do.  The <samp>-o filenames</samp> option tells Readline
+that the possible completions should be treated as filenames, and quoted
+appropriately.  That option will also cause Readline to append a slash to
+filenames it can determine are directories (which is why we might want to
+extend <code>_comp_cd</code> to append a slash if we&rsquo;re using directories found
+via <var>CDPATH</var>: Readline can&rsquo;t tell those completions are directories).
+The <samp>-o nospace</samp> option tells Readline to not append a space
+character to the directory name, in case we want to append to it.
+The <samp>-o bashdefault</samp> option brings in the rest of the &quot;Bash default&quot;
+completions &ndash; possible completions that Bash adds to the default Readline
+set.  These include things like command name completion, variable completion
+for words beginning with &lsquo;<samp>$</samp>&rsquo; or &lsquo;<samp>${</samp>&rsquo;, completions containing pathname
+expansion patterns (see <a href="#Filename-Expansion">Filename Expansion</a>), and so on.
+</p>
+<p>Once installed using <code>complete</code>, <code>_comp_cd</code> will be called every
+time we attempt word completion for a <code>cd</code> command.
+</p>
+<p>Many more examples &ndash; an extensive collection of completions for most of
+the common GNU, Unix, and Linux commands &ndash; are available as part of the
+bash_completion project.  This is installed by default on many GNU/Linux
+distributions.  Originally written by Ian Macdonald, the project now lives
+at <a href="https://github.com/scop/bash-completion/">https://github.com/scop/bash-completion/</a>.  There are ports for
+other systems such as Solaris and Mac OS X.
+</p>
+<p>An older version of the bash_completion package is distributed with bash
+in the <samp>examples/complete</samp> subdirectory.

+
+<p>When the <samp>-o history</samp> option to the <code>set</code> builtin
+is enabled (see <a href="#The-Set-Builtin">The Set Builtin</a>),
+the shell provides access to the <em>command history</em>,
+the list of commands previously typed.
+The value of the <code>HISTSIZE</code> shell variable is used as the
+number of commands to save in a history list.
+The text of the last <code>$HISTSIZE</code>
+commands (default 500) is saved.
+The shell stores each command in the history list prior to
+parameter and variable expansion
+but after history expansion is performed, subject to the
+values of the shell variables
+<code>HISTIGNORE</code> and <code>HISTCONTROL</code>.
+</p>
+<p>When the shell starts up, the history is initialized from the
+file named by the <code>HISTFILE</code> variable (default <samp>~/.bash_history</samp>).
+The file named by the value of <code>HISTFILE</code> is truncated, if
+necessary, to contain no more than the number of lines specified by
+the value of the <code>HISTFILESIZE</code> variable.
+When a shell with history enabled exits, the last
+<code>$HISTSIZE</code> lines are copied from the history list to the file
+named by <code>$HISTFILE</code>.
+If the <code>histappend</code> shell option is set (see <a href="#Bash-Builtins">Bash Builtin Commands</a>),
+the lines are appended to the history file,
+otherwise the history file is overwritten.
+If <code>HISTFILE</code>
+is unset, or if the history file is unwritable, the history is not saved.
+After saving the history, the history file is truncated
+to contain no more than <code>$HISTFILESIZE</code> lines.
+If <code>HISTFILESIZE</code> is unset, or set to null, a non-numeric value, or
+a numeric value less than zero, the history file is not truncated.
+</p>
+<p>If the <code>HISTTIMEFORMAT</code> is set, the time stamp information
+associated with each history entry is written to the history file,
+marked with the history comment character.
+When the history file is read, lines beginning with the history
+comment character followed immediately by a digit are interpreted
+as timestamps for the following history entry.
+</p>
+<p>The builtin command <code>fc</code> may be used to list or edit and re-execute
+a portion of the history list.
+The <code>history</code> builtin may be used to display or modify the history
+list and manipulate the history file.
+When using command-line editing, search commands
+are available in each editing mode that provide access to the
+history list (see <a href="#Commands-For-History">Commands For Manipulating The History</a>).
+</p>
+<p>The shell allows control over which commands are saved on the history
+list.  The <code>HISTCONTROL</code> and <code>HISTIGNORE</code>
+variables may be set to cause the shell to save only a subset of the
+commands entered.
+The <code>cmdhist</code>
+shell option, if enabled, causes the shell to attempt to save each
+line of a multi-line command in the same history entry, adding
+semicolons where necessary to preserve syntactic correctness.
+The <code>lithist</code>
+shell option causes the shell to save the command with embedded newlines
+instead of semicolons.
+The <code>shopt</code> builtin is used to set these options.
+See <a href="#The-Shopt-Builtin">The Shopt Builtin</a>, for a description of <code>shopt</code>.

+<p>Bash provides two builtin commands which manipulate the
+history list and history file.
+</p>
+<dl compact="compact">
+<dt id='index-fc'><span><code>fc</code><a href='#index-fc' class='copiable-anchor'> &para;</a></span></dt>
+<dd><div class="example">
+<pre class="example"><code>fc [-e <var>ename</var>] [-lnr] [<var>first</var>] [<var>last</var>]</code>
+<code>fc -s [<var>pat</var>=<var>rep</var>] [<var>command</var>]</code>
+</pre></div>
+
+<p>The first form selects a range of commands from <var>first</var> to
+<var>last</var> from the history list and displays or edits and re-executes
+them.
+Both <var>first</var> and
+<var>last</var> may be specified as a string (to locate the most recent
+command beginning with that string) or as a number (an index into the
+history list, where a negative number is used as an offset from the
+current command number).
+</p>
+<p>When listing, a <var>first</var> or <var>last</var> of 0 is equivalent to -1
+and -0 is equivalent to the current command (usually the <code>fc</code>
+command);
+otherwise 0 is equivalent to -1 and -0 is invalid.
+</p>
+<p>If <var>last</var> is not specified, it is set to
+<var>first</var>.  If <var>first</var> is not specified, it is set to the previous
+command for editing and -16 for listing.  If the <samp>-l</samp> flag is
+given, the commands are listed on standard output.  The <samp>-n</samp> flag
+suppresses the command numbers when listing.  The <samp>-r</samp> flag
+reverses the order of the listing.  Otherwise, the editor given by
+<var>ename</var> is invoked on a file containing those commands.  If
+<var>ename</var> is not given, the value of the following variable expansion
+is used: <code>${FCEDIT:-${EDITOR:-vi}}</code>.  This says to use the
+value of the <code>FCEDIT</code> variable if set, or the value of the
+<code>EDITOR</code> variable if that is set, or <code>vi</code> if neither is set.
+When editing is complete, the edited commands are echoed and executed.
+</p>
+<p>In the second form, <var>command</var> is re-executed after each instance
+of <var>pat</var> in the selected command is replaced by <var>rep</var>.
+<var>command</var> is interpreted the same as <var>first</var> above.
+</p>
+<p>A useful alias to use with the <code>fc</code> command is <code>r='fc -s'</code>, so
+that typing &lsquo;<samp>r cc</samp>&rsquo; runs the last command beginning with <code>cc</code>
+and typing &lsquo;<samp>r</samp>&rsquo; re-executes the last command (see <a href="#Aliases">Aliases</a>).

+An argument of <var>n</var> lists only the last <var>n</var> lines.
+If the shell variable <code>HISTTIMEFORMAT</code> is set and not null,
+it is used as a format string for <var>strftime</var> to display
+the time stamp associated with each displayed history entry.
+No intervening blank is printed between the formatted time stamp
+and the history line.

+If <var>offset</var> is positive, it should be specified as it appears when

+If <var>offset</var> is negative, it is interpreted as relative to one greater
+than the last history position, so negative indices count back from the
+end of the history, and an index of &lsquo;<samp>-1</samp>&rsquo; refers to the current

+
+<p>The History library provides a history expansion feature that is similar
+to the history expansion provided by <code>csh</code>.  This section
+describes the syntax used to manipulate the history information.
+</p>
+<p>History expansions introduce words from the history list into
+the input stream, making it easy to repeat commands, insert the
+arguments to a previous command into the current input line, or
+fix errors in previous commands quickly.
+</p>
+<p>History expansion is performed immediately after a complete line
+is read, before the shell breaks it into words, and is performed
+on each line individually.  Bash attempts to inform the history
+expansion functions about quoting still in effect from previous lines.
+</p>
+<p>History expansion takes place in two parts.  The first is to determine
+which line from the history list should be used during substitution.
+The second is to select portions of that line for inclusion into the
+current one.  The line selected from the history is called the
+<em>event</em>, and the portions of that line that are acted upon are
+called <em>words</em>.  Various <em>modifiers</em> are available to manipulate
+the selected words.  The line is broken into words in the same fashion
+that Bash does, so that several words
+surrounded by quotes are considered one word.
+History expansions are introduced by the appearance of the
+history expansion character, which is &lsquo;<samp>!</samp>&rsquo; by default.
+</p>
+<p>History expansion implements shell-like quoting conventions:
+a backslash can be used to remove the special handling for the next character;
+single quotes enclose verbatim sequences of characters, and can be used to
+inhibit history expansion;
+and characters enclosed within double quotes may be subject to history
+expansion, since backslash can escape the history expansion character,
+but single quotes may not, since they are not treated specially within
+double quotes.
+</p>
+<p>When using the shell, only &lsquo;<samp>\</samp>&rsquo; and &lsquo;<samp>'</samp>&rsquo; may be used to escape the
+history expansion character, but the history expansion character is
+also treated as quoted if it immediately precedes the closing double quote
+in a double-quoted string. 
+</p>
+<p>Several shell options settable with the <code>shopt</code>
+builtin (see <a href="#The-Shopt-Builtin">The Shopt Builtin</a>) may be used to tailor
+the behavior of history expansion.  If the
+<code>histverify</code> shell option is enabled, and Readline
+is being used, history substitutions are not immediately passed to
+the shell parser.
+Instead, the expanded line is reloaded into the Readline
+editing buffer for further modification.
+If Readline is being used, and the <code>histreedit</code>
+shell option is enabled, a failed history expansion will be
+reloaded into the Readline editing buffer for correction.
+The <samp>-p</samp> option to the <code>history</code> builtin command
+may be used to see what a history expansion will do before using it.
+The <samp>-s</samp> option to the <code>history</code> builtin may be used to
+add commands to the end of the history list without actually executing
+them, so that they are available for subsequent recall.
+This is most useful in conjunction with Readline.
+</p>
+<p>The shell allows control of the various characters used by the
+history expansion mechanism with the <code>histchars</code> variable,
+as explained above (see <a href="#Bash-Variables">Bash Variables</a>).  The shell uses
+the history comment character to mark history timestamps when
+writing the history file.

+<span id="index-Bash-installation"></span>
+<span id="index-Bash-configuration"></span>
+
+<p>These are installation instructions for Bash.
+</p>
+<p>The simplest way to compile Bash is:
+</p>
+<ol>
+<li> <code>cd</code> to the directory containing the source code and type
+&lsquo;<samp>./configure</samp>&rsquo; to configure Bash for your system.  If you&rsquo;re
+using <code>csh</code> on an old version of System V, you might need to
+type &lsquo;<samp>sh ./configure</samp>&rsquo; instead to prevent <code>csh</code> from trying
+to execute <code>configure</code> itself.
+
+<p>Running <code>configure</code> takes some time.
+While running, it prints messages telling which features it is
+checking for.
+</p>
+</li><li> Type &lsquo;<samp>make</samp>&rsquo; to compile Bash and build the <code>bashbug</code> bug
+reporting script.
+
+</li><li> Optionally, type &lsquo;<samp>make tests</samp>&rsquo; to run the Bash test suite.
+
+</li><li> Type &lsquo;<samp>make install</samp>&rsquo; to install <code>bash</code> and <code>bashbug</code>.
+This will also install the manual pages and Info file, message translation
+files, some supplemental documentation, a number of example loadable
+builtin commands, and a set of header files for developing loadable
+builtins.
+You may need additional privileges to install <code>bash</code> to your
+desired destination, so &lsquo;<samp>sudo make install</samp>&rsquo; might be required.
+More information about controlling the locations where <code>bash</code> and
+other files are installed is below (see <a href="#Installation-Names">Installation Names</a>).
+
+</li></ol>
+
+<p>The <code>configure</code> shell script attempts to guess correct
+values for various system-dependent variables used during
+compilation.  It uses those values to create a <samp>Makefile</samp> in
+each directory of the package (the top directory, the
+<samp>builtins</samp>, <samp>doc</samp>, <samp>po</samp>, and <samp>support</samp> directories,
+each directory under <samp>lib</samp>, and several others).  It also creates a
+<samp>config.h</samp> file containing system-dependent definitions. 
+Finally, it creates a shell script named <code>config.status</code> that you
+can run in the future to recreate the current configuration, a
+file <samp>config.cache</samp> that saves the results of its tests to
+speed up reconfiguring, and a file <samp>config.log</samp> containing
+compiler output (useful mainly for debugging <code>configure</code>). 
+If at some point
+<samp>config.cache</samp> contains results you don&rsquo;t want to keep, you
+may remove or edit it. 
+</p>
+<p>To find out more about the options and arguments that the
+<code>configure</code> script understands, type 
+</p>
+<div class="example">
+<pre class="example">bash-4.2$ ./configure --help
+</pre></div>
+
+<p>at the Bash prompt in your Bash source directory.
+</p>
+<p>If you want to build Bash in a directory separate from the source
+directory &ndash; to build for multiple architectures, for example &ndash;
+just use the full path to the configure script. The following commands
+will build bash in a directory under <samp>/usr/local/build</samp> from
+the source code in <samp>/usr/local/src/bash-4.4</samp>:
+</p>
+<div class="example">
+<pre class="example">mkdir /usr/local/build/bash-4.4
+cd /usr/local/build/bash-4.4
+bash /usr/local/src/bash-4.4/configure
+make
+</pre></div>
+
+<p>See <a href="#Compiling-For-Multiple-Architectures">Compiling For Multiple Architectures</a> for more information
+about building in a directory separate from the source.
+</p>
+<p>If you need to do unusual things to compile Bash, please
+try to figure out how <code>configure</code> could check whether or not
+to do them, and mail diffs or instructions to
+<a href="mailto:bash-maintainers@gnu.org">bash-maintainers@gnu.org</a> so they can be
+considered for the next release.
+</p>
+<p>The file <samp>configure.ac</samp> is used to create <code>configure</code>
+by a program called Autoconf.
+You only need <samp>configure.ac</samp> if you want to change it or regenerate
+<code>configure</code> using a newer version of Autoconf.
+If you do this, make sure you are using Autoconf version 2.69 or
+newer.
+</p>
+<p>You can remove the program binaries and object files from the
+source code directory by typing &lsquo;<samp>make clean</samp>&rsquo;.  To also remove the
+files that <code>configure</code> created (so you can compile Bash for
+a different kind of computer), type &lsquo;<samp>make distclean</samp>&rsquo;.

+
+<p>Some systems require unusual options for compilation or linking
+that the <code>configure</code> script does not know about.  You can
+give <code>configure</code> initial values for variables by setting
+them in the environment.  Using a Bourne-compatible shell, you
+can do that on the command line like this:
+</p>
+<div class="example">
+<pre class="example">CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+</pre></div>
+
+<p>On systems that have the <code>env</code> program, you can do it like this:
+</p>
+<div class="example">
+<pre class="example">env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+</pre></div>
+
+<p>The configuration process uses GCC to build Bash if it
+is available.

+<span id="Compiling-For-Multiple-Architectures-1"></span><h3 class="section">10.3 Compiling For Multiple Architectures</h3>
+
+<p>You can compile Bash for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of <code>make</code> that
+supports the <code>VPATH</code> variable, such as GNU <code>make</code>.
+<code>cd</code> to the
+directory where you want the object files and executables to go and run
+the <code>configure</code> script from the source directory
+(see <a href="#Basic-Installation">Basic Installation</a>).
+You may need to
+supply the <samp>--srcdir=PATH</samp> argument to tell <code>configure</code> where the
+source files are.  <code>configure</code> automatically checks for the
+source code in the directory that <code>configure</code> is in and in &lsquo;..&rsquo;.
+</p>
+<p>If you have to use a <code>make</code> that does not support the <code>VPATH</code>
+variable, you can compile Bash for one architecture at a
+time in the source code directory.  After you have installed
+Bash for one architecture, use &lsquo;<samp>make distclean</samp>&rsquo; before
+reconfiguring for another architecture.
+</p>
+<p>Alternatively, if your system supports symbolic links, you can use the
+<samp>support/mkclone</samp> script to create a build tree which has
+symbolic links back to each file in the source directory.  Here&rsquo;s an
+example that creates a build directory in the current directory from a
+source directory <samp>/usr/gnu/src/bash-2.0</samp>:
+</p>
+<div class="example">
+<pre class="example">bash /usr/gnu/src/bash-2.0/support/mkclone -s /usr/gnu/src/bash-2.0 .
+</pre></div>
+
+<p>The <code>mkclone</code> script requires Bash, so you must have already built
+Bash for at least one architecture before you can create build
+directories for other architectures.

+<p>By default, &lsquo;<samp>make install</samp>&rsquo; will install into
+<samp>/usr/local/bin</samp>, <samp>/usr/local/man</samp>, etc.;
+that is, the <em>installation prefix</em> defaults to <samp>/usr/local</samp>.
+You can specify an installation prefix other than <samp>/usr/local</samp> by
+giving <code>configure</code> the option <samp>--prefix=<var>PATH</var></samp>,
+or by specifying a value for the <code>prefix</code> &lsquo;<samp>make</samp>&rsquo;
+variable when running &lsquo;<samp>make install</samp>&rsquo;
+(e.g., &lsquo;<samp>make install prefix=<var>PATH</var></samp>&rsquo;).
+The <code>prefix</code> variable provides a default for <code>exec_prefix</code> and
+other variables used when installing bash.
+</p>
+<p>You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. 
+If you give <code>configure</code> the option
+<samp>--exec-prefix=<var>PATH</var></samp>, &lsquo;<samp>make install</samp>&rsquo; will use
+<var>PATH</var> as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+</p>
+<p>If you would like to change the installation locations for a single run,
+you can specify these variables as arguments to <code>make</code>:
+&lsquo;<samp>make install exec_prefix=/</samp>&rsquo; will install <code>bash</code> and
+<code>bashbug</code> into <samp>/bin</samp> instead of the default <samp>/usr/local/bin</samp>.
+</p>
+<p>If you want to see the files bash will install and where it will install
+them without changing anything on your system, specify the variable
+<code>DESTDIR</code> as an argument to <code>make</code>. Its value should be the
+absolute directory path you&rsquo;d like to use as the root of your sample
+installation tree. For example,
+</p>
+<div class="example">
+<pre class="example">mkdir /fs1/bash-install
+make install DESTDIR=/fs1/bash-install
+</pre></div>
+
+<p>will install <code>bash</code> into <samp>/fs1/bash-install/usr/local/bin/bash</samp>,
+the documentation into directories within
+<samp>/fs1/bash-install/usr/local/share</samp>, the example loadable builtins into
+<samp>/fs1/bash-install/usr/local/lib/bash</samp>, and so on.
+You can use the usual <code>exec_prefix</code> and <code>prefix</code> variables to alter
+the directory paths beneath the value of <code>DESTDIR</code>.
+</p>
+<p>The GNU Makefile standards provide a more complete description of these
+variables and their effects.

+There are also several <samp>--with-<var>package</var></samp> options,

+originally derived from the 4.2 <small>BSD</small> <code>malloc</code>.  This <code>malloc</code>
+is very fast, but wastes some space on each allocation.
+This option is enabled by default.
+The <samp>NOTES</samp> file contains a list of systems for

+
+<p>Bash implements essentially the same grammar, parameter and
+variable expansion, redirection, and quoting as the Bourne Shell. 
+Bash uses the <small>POSIX</small> standard as the specification of
+how these features are to be implemented.  There are some
+differences between the traditional Bourne shell and Bash; this
+section quickly details the differences of significance.  A
+number of these differences are explained in greater depth in
+previous sections.
+This section uses the version of <code>sh</code> included in SVR4.2 (the
+last version of the historical Bourne shell) as the baseline reference.
+</p>
+<ul>
+<li> Bash is <small>POSIX</small>-conformant, even where the <small>POSIX</small> specification
+differs from traditional <code>sh</code> behavior (see <a href="#Bash-POSIX-Mode">Bash POSIX Mode</a>).
+
+</li><li> Bash has multi-character invocation options (see <a href="#Invoking-Bash">Invoking Bash</a>).
+
+</li><li> Bash has command-line editing (see <a href="#Command-Line-Editing">Command Line Editing</a>) and
+the <code>bind</code> builtin.
+
+</li><li> Bash provides a programmable word completion mechanism
+(see <a href="#Programmable-Completion">Programmable Completion</a>), and builtin commands
+<code>complete</code>, <code>compgen</code>, and <code>compopt</code>, to
+manipulate it.

+</li><li> Bash has command history (see <a href="#Bash-History-Facilities">Bash History Facilities</a>) and the
+<code>history</code> and <code>fc</code> builtins to manipulate it.
+The Bash history list maintains timestamp information and uses the
+value of the <code>HISTTIMEFORMAT</code> variable to display it.
+
+</li><li> Bash implements <code>csh</code>-like history expansion
+(see <a href="#History-Interaction">History Expansion</a>).
+
+</li><li> Bash has one-dimensional array variables (see <a href="#Arrays">Arrays</a>), and the
+appropriate variable expansions and assignment syntax to use them.
+Several of the Bash builtins take options to act on arrays.
+Bash provides a number of built-in array variables.
+
+</li><li> The <code>$'&hellip;'</code> quoting syntax, which expands ANSI-C
+backslash-escaped characters in the text between the single quotes,
+is supported (see <a href="#ANSI_002dC-Quoting">ANSI-C Quoting</a>).
+
+</li><li> Bash supports the <code>$&quot;&hellip;&quot;</code> quoting syntax to do
+locale-specific translation of the characters between the double
+quotes.  The <samp>-D</samp>, <samp>--dump-strings</samp>, and <samp>--dump-po-strings</samp>
+invocation options list the translatable strings found in a script
+(see <a href="#Locale-Translation">Locale-Specific Translation</a>).
+
+</li><li> Bash implements the <code>!</code> keyword to negate the return value of
+a pipeline (see <a href="#Pipelines">Pipelines</a>).
+Very useful when an <code>if</code> statement needs to act only if a test fails.
+The Bash &lsquo;<samp>-o pipefail</samp>&rsquo; option to <code>set</code> will cause a pipeline to
+return a failure status if any command fails.
+
+</li><li> Bash has the <code>time</code> reserved word and command timing (see <a href="#Pipelines">Pipelines</a>).
+The display of the timing statistics may be controlled with the
+<code>TIMEFORMAT</code> variable.
+
+</li><li> Bash implements the <code>for (( <var>expr1</var> ; <var>expr2</var> ; <var>expr3</var> ))</code>
+arithmetic for command, similar to the C language (see <a href="#Looping-Constructs">Looping Constructs</a>).
+
+</li><li> Bash includes the <code>select</code> compound command, which allows the
+generation of simple menus (see <a href="#Conditional-Constructs">Conditional Constructs</a>).
+
+</li><li> Bash includes the <code>[[</code> compound command, which makes conditional
+testing part of the shell grammar (see <a href="#Conditional-Constructs">Conditional Constructs</a>), including
+optional regular expression matching.
+
+</li><li> Bash provides optional case-insensitive matching for the <code>case</code> and
+<code>[[</code> constructs.
+
+</li><li> Bash includes brace expansion (see <a href="#Brace-Expansion">Brace Expansion</a>) and tilde
+expansion (see <a href="#Tilde-Expansion">Tilde Expansion</a>).
+
+</li><li> Bash implements command aliases and the <code>alias</code> and <code>unalias</code>
+builtins (see <a href="#Aliases">Aliases</a>).
+
+</li><li> Bash provides shell arithmetic, the <code>((</code> compound command
+(see <a href="#Conditional-Constructs">Conditional Constructs</a>),
+and arithmetic expansion (see <a href="#Shell-Arithmetic">Shell Arithmetic</a>).
+
+</li><li> Variables present in the shell&rsquo;s initial environment are automatically
+exported to child processes.  The Bourne shell does not normally do
+this unless the variables are explicitly marked using the <code>export</code>
+command.
+
+</li><li> Bash supports the &lsquo;<samp>+=</samp>&rsquo; assignment operator, which appends to the value
+of the variable named on the left hand side.
+
+</li><li> Bash includes the <small>POSIX</small> pattern removal &lsquo;<samp>%</samp>&rsquo;, &lsquo;<samp>#</samp>&rsquo;, &lsquo;<samp>%%</samp>&rsquo;
+and &lsquo;<samp>##</samp>&rsquo; expansions to remove leading or trailing substrings from
+variable values (see <a href="#Shell-Parameter-Expansion">Shell Parameter Expansion</a>).
+
+</li><li> The expansion <code>${#xx}</code>, which returns the length of <code>${xx}</code>,
+is supported (see <a href="#Shell-Parameter-Expansion">Shell Parameter Expansion</a>).
+
+</li><li> The expansion <code>${var:</code><var>offset</var><code>[:</code><var>length</var><code>]}</code>,
+which expands to the substring of <code>var</code>&rsquo;s value of length
+<var>length</var>, beginning at <var>offset</var>, is present
+(see <a href="#Shell-Parameter-Expansion">Shell Parameter Expansion</a>).
+
+</li><li> The expansion
+<code>${<var>var</var>/[/]</code><var>pattern</var><code>[/</code><var>replacement</var><code>]}</code>,
+which matches <var>pattern</var> and replaces it with <var>replacement</var> in
+the value of <var>var</var>, is available (see <a href="#Shell-Parameter-Expansion">Shell Parameter Expansion</a>).
+
+</li><li> The expansion <code>${!<var>prefix</var>*}</code> expansion, which expands to
+the names of all shell variables whose names begin with <var>prefix</var>,
+is available (see <a href="#Shell-Parameter-Expansion">Shell Parameter Expansion</a>).
+
+</li><li> Bash has indirect variable expansion using <code>${!word}</code>
+(see <a href="#Shell-Parameter-Expansion">Shell Parameter Expansion</a>).
+
+</li><li> Bash can expand positional parameters beyond <code>$9</code> using
+<code>${<var>num</var>}</code>.
+
+</li><li> The <small>POSIX</small> <code>$()</code> form of command substitution
+is implemented (see <a href="#Command-Substitution">Command Substitution</a>),
+and preferred to the Bourne shell&rsquo;s <code>``</code> (which
+is also implemented for backwards compatibility).
+
+</li><li> Bash has process substitution (see <a href="#Process-Substitution">Process Substitution</a>).
+
+</li><li> Bash automatically assigns variables that provide information about the
+current user (<code>UID</code>, <code>EUID</code>, and <code>GROUPS</code>), the current host
+(<code>HOSTTYPE</code>, <code>OSTYPE</code>, <code>MACHTYPE</code>, and <code>HOSTNAME</code>),
+and the instance of Bash that is running (<code>BASH</code>,
+<code>BASH_VERSION</code>, and <code>BASH_VERSINFO</code>).  See <a href="#Bash-Variables">Bash Variables</a>,
+for details.
+
+</li><li> The <code>IFS</code> variable is used to split only the results of expansion,
+not all words (see <a href="#Word-Splitting">Word Splitting</a>).
+This closes a longstanding shell security hole.
+
+</li><li> The filename expansion bracket expression code uses &lsquo;<samp>!</samp>&rsquo; and &lsquo;<samp>^</samp>&rsquo;
+to negate the set of characters between the brackets.
+The Bourne shell uses only &lsquo;<samp>!</samp>&rsquo;.
+
+</li><li> Bash implements the full set of <small>POSIX</small> filename expansion operators,
+including character classes, equivalence classes, and
+collating symbols (see <a href="#Filename-Expansion">Filename Expansion</a>).
+
+</li><li> Bash implements extended pattern matching features when the <code>extglob</code>
+shell option is enabled (see <a href="#Pattern-Matching">Pattern Matching</a>).
+
+</li><li> It is possible to have a variable and a function with the same name;
+<code>sh</code> does not separate the two name spaces.
+
+</li><li> Bash functions are permitted to have local variables using the
+<code>local</code> builtin, and thus useful recursive functions may be written
+(see <a href="#Bash-Builtins">Bash Builtin Commands</a>).
+
+</li><li> Variable assignments preceding commands affect only that command, even
+builtins and functions (see <a href="#Environment">Environment</a>).
+In <code>sh</code>, all variable assignments 
+preceding commands are global unless the command is executed from the
+file system.
+
+</li><li> Bash performs filename expansion on filenames specified as operands
+to input and output redirection operators (see <a href="#Redirections">Redirections</a>).
+
+</li><li> Bash contains the &lsquo;<samp>&lt;&gt;</samp>&rsquo; redirection operator, allowing a file to be
+opened for both reading and writing, and the &lsquo;<samp>&amp;&gt;</samp>&rsquo; redirection
+operator, for directing standard output and standard error to the same
+file (see <a href="#Redirections">Redirections</a>).
+
+</li><li> Bash includes the &lsquo;<samp>&lt;&lt;&lt;</samp>&rsquo; redirection operator, allowing a string to
+be used as the standard input to a command.
+
+</li><li> Bash implements the &lsquo;<samp>[n]&lt;&amp;<var>word</var></samp>&rsquo; and &lsquo;<samp>[n]&gt;&amp;<var>word</var></samp>&rsquo;
+redirection operators, which move one file descriptor to another.
+
+</li><li> Bash treats a number of filenames specially when they are
+used in redirection operators (see <a href="#Redirections">Redirections</a>).
+
+</li><li> Bash can open network connections to arbitrary machines and services
+with the redirection operators (see <a href="#Redirections">Redirections</a>).
+
+</li><li> The <code>noclobber</code> option is available to avoid overwriting existing
+files with output redirection (see <a href="#The-Set-Builtin">The Set Builtin</a>).
+The &lsquo;<samp>&gt;|</samp>&rsquo; redirection operator may be used to override <code>noclobber</code>.
+
+</li><li> The Bash <code>cd</code> and <code>pwd</code> builtins (see <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>)
+each take <samp>-L</samp> and <samp>-P</samp> options to switch between logical and
+physical modes.
+
+</li><li> Bash allows a function to override a builtin with the same name, and provides
+access to that builtin&rsquo;s functionality within the function via the
+<code>builtin</code> and <code>command</code> builtins (see <a href="#Bash-Builtins">Bash Builtin Commands</a>).
+
+</li><li> The <code>command</code> builtin allows selective disabling of functions
+when command lookup is performed (see <a href="#Bash-Builtins">Bash Builtin Commands</a>).
+
+</li><li> Individual builtins may be enabled or disabled using the <code>enable</code>
+builtin (see <a href="#Bash-Builtins">Bash Builtin Commands</a>).
+
+</li><li> The Bash <code>exec</code> builtin takes additional options that allow users
+to control the contents of the environment passed to the executed
+command, and what the zeroth argument to the command is to be
+(see <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>).
+
+</li><li> Shell functions may be exported to children via the environment
+using <code>export -f</code> (see <a href="#Shell-Functions">Shell Functions</a>).
+
+</li><li> The Bash <code>export</code>, <code>readonly</code>, and <code>declare</code> builtins can
+take a <samp>-f</samp> option to act on shell functions, a <samp>-p</samp> option to
+display variables with various attributes set in a format that can be
+used as shell input, a <samp>-n</samp> option to remove various variable
+attributes, and &lsquo;<samp>name=value</samp>&rsquo; arguments to set variable attributes
+and values simultaneously.
+
+</li><li> The Bash <code>hash</code> builtin allows a name to be associated with
+an arbitrary filename, even when that filename cannot be found by
+searching the <code>$PATH</code>, using &lsquo;<samp>hash -p</samp>&rsquo;
+(see <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>).
+
+</li><li> Bash includes a <code>help</code> builtin for quick reference to shell
+facilities (see <a href="#Bash-Builtins">Bash Builtin Commands</a>).
+
+</li><li> The <code>printf</code> builtin is available to display formatted output
+(see <a href="#Bash-Builtins">Bash Builtin Commands</a>).
+
+</li><li> The Bash <code>read</code> builtin (see <a href="#Bash-Builtins">Bash Builtin Commands</a>)
+will read a line ending in &lsquo;<samp>\</samp>&rsquo; with
+the <samp>-r</samp> option, and will use the <code>REPLY</code> variable as a
+default if no non-option arguments are supplied.
+The Bash <code>read</code> builtin
+also accepts a prompt string with the <samp>-p</samp> option and will use
+Readline to obtain the line when given the <samp>-e</samp> option.
+The <code>read</code> builtin also has additional options to control input:
+the <samp>-s</samp> option will turn off echoing of input characters as
+they are read, the <samp>-t</samp> option will allow <code>read</code> to time out
+if input does not arrive within a specified number of seconds, the
+<samp>-n</samp> option will allow reading only a specified number of
+characters rather than a full line, and the <samp>-d</samp> option will read
+until a particular character rather than newline.
+
+</li><li> The <code>return</code> builtin may be used to abort execution of scripts
+executed with the <code>.</code> or <code>source</code> builtins
+(see <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>).
+
+</li><li> Bash includes the <code>shopt</code> builtin, for finer control of shell
+optional capabilities (see <a href="#The-Shopt-Builtin">The Shopt Builtin</a>), and allows these options
+to be set and unset at shell invocation (see <a href="#Invoking-Bash">Invoking Bash</a>).
+
+</li><li> Bash has much more optional behavior controllable with the <code>set</code>
+builtin (see <a href="#The-Set-Builtin">The Set Builtin</a>).
+
+</li><li> The &lsquo;<samp>-x</samp>&rsquo; (<samp>xtrace</samp>) option displays commands other than
+simple commands when performing an execution trace
+(see <a href="#The-Set-Builtin">The Set Builtin</a>).
+
+</li><li> The <code>test</code> builtin (see <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>)
+is slightly different, as it implements the <small>POSIX</small> algorithm,
+which specifies the behavior based on the number of arguments.
+
+</li><li> Bash includes the <code>caller</code> builtin, which displays the context of
+any active subroutine call (a shell function or a script executed with
+the <code>.</code> or <code>source</code> builtins).  This supports the Bash
+debugger.
+
+</li><li> The <code>trap</code> builtin (see <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>) allows a
+<code>DEBUG</code> pseudo-signal specification, similar to <code>EXIT</code>.
+Commands specified with a <code>DEBUG</code> trap are executed before every
+simple command, <code>for</code> command, <code>case</code> command,
+<code>select</code> command, every arithmetic <code>for</code> command, and before
+the first command executes in a shell function.
+The <code>DEBUG</code> trap is not inherited by shell functions unless the
+function has been given the <code>trace</code> attribute or the
+<code>functrace</code> option has been enabled using the <code>shopt</code> builtin.
+The <code>extdebug</code> shell option has additional effects on the
+<code>DEBUG</code> trap.
+
+<p>The <code>trap</code> builtin (see <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>) allows an
+<code>ERR</code> pseudo-signal specification, similar to <code>EXIT</code> and <code>DEBUG</code>.
+Commands specified with an <code>ERR</code> trap are executed after a simple
+command fails, with a few exceptions.
+The <code>ERR</code> trap is not inherited by shell functions unless the
+<code>-o errtrace</code> option to the <code>set</code> builtin is enabled.
+</p>
+<p>The <code>trap</code> builtin (see <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>) allows a
+<code>RETURN</code> pseudo-signal specification, similar to
+<code>EXIT</code> and <code>DEBUG</code>.
+Commands specified with a <code>RETURN</code> trap are executed before
+execution resumes after a shell function or a shell script executed with
+<code>.</code> or <code>source</code> returns.
+The <code>RETURN</code> trap is not inherited by shell functions unless the
+function has been given the <code>trace</code> attribute or the
+<code>functrace</code> option has been enabled using the <code>shopt</code> builtin.
+</p>
+</li><li> The Bash <code>type</code> builtin is more extensive and gives more information
+about the names it finds (see <a href="#Bash-Builtins">Bash Builtin Commands</a>).
+
+</li><li> The Bash <code>umask</code> builtin permits a <samp>-p</samp> option to cause
+the output to be displayed in the form of a <code>umask</code> command
+that may be reused as input (see <a href="#Bourne-Shell-Builtins">Bourne Shell Builtins</a>).
+
+</li><li> Bash implements a <code>csh</code>-like directory stack, and provides the
+<code>pushd</code>, <code>popd</code>, and <code>dirs</code> builtins to manipulate it
+(see <a href="#The-Directory-Stack">The Directory Stack</a>).
+Bash also makes the directory stack visible as the value of the
+<code>DIRSTACK</code> shell variable.
+
+</li><li> Bash interprets special backslash-escaped characters in the prompt
+strings when interactive (see <a href="#Controlling-the-Prompt">Controlling the Prompt</a>).
+
+</li><li> The Bash restricted mode is more useful (see <a href="#The-Restricted-Shell">The Restricted Shell</a>);
+the SVR4.2 shell restricted mode is too limited.
+
+</li><li> The <code>disown</code> builtin can remove a job from the internal shell
+job table (see <a href="#Job-Control-Builtins">Job Control Builtins</a>) or suppress the sending
+of <code>SIGHUP</code> to a job when the shell exits as the result of a
+<code>SIGHUP</code>.
+
+</li><li> Bash includes a number of features to support a separate debugger for
+shell scripts.
+
+</li><li> The SVR4.2 shell has two privilege-related builtins
+(<code>mldmode</code> and <code>priv</code>) not present in Bash.
+
+</li><li> Bash does not have the <code>stop</code> or <code>newgrp</code> builtins.
+
+</li><li> Bash does not use the <code>SHACCT</code> variable or perform shell accounting.
+
+</li><li> The SVR4.2 <code>sh</code> uses a <code>TIMEOUT</code> variable like Bash uses
+<code>TMOUT</code>.
+
+</li></ul>

+<div class="appendixsec" id="Implementation-Differences-From-The-SVR4_002e2-Shell">
+<h3 class="appendixsec">B.1 Implementation Differences From The SVR4.2 Shell</h3>
+
+<p>Since Bash is a completely new implementation, it does not suffer from
+many of the limitations of the SVR4.2 shell.  For instance:
+</p>
+<ul>
+<li> Bash does not fork a subshell when redirecting into or out of
+a shell control structure such as  an <code>if</code> or <code>while</code>
+statement.
+
+</li><li> Bash does not allow unbalanced quotes.  The SVR4.2 shell will silently
+insert a needed closing quote at <code>EOF</code> under certain circumstances.
+This can be the cause of some hard-to-find errors.
+
+</li><li> The SVR4.2 shell uses a baroque memory management scheme based on
+trapping <code>SIGSEGV</code>.  If the shell is started from a process with
+<code>SIGSEGV</code> blocked (e.g., by using the <code>system()</code> C library
+function call), it misbehaves badly.
+
+</li><li> In a questionable attempt at security, the SVR4.2 shell,
+when invoked without the <samp>-p</samp> option, will alter its real
+and effective <small>UID</small> and <small>GID</small> if they are less than some
+magic threshold value, commonly 100.
+This can lead to unexpected results.
+
+</li><li> The SVR4.2 shell does not allow users to trap <code>SIGSEGV</code>,
+<code>SIGALRM</code>, or <code>SIGCHLD</code>.
+
+</li><li> The SVR4.2 shell does not allow the <code>IFS</code>, <code>MAILCHECK</code>,
+<code>PATH</code>, <code>PS1</code>, or <code>PS2</code> variables to be unset.
+
+</li><li> The SVR4.2 shell treats &lsquo;<samp>^</samp>&rsquo; as the undocumented equivalent of
+&lsquo;<samp>|</samp>&rsquo;.
+
+</li><li> Bash allows multiple option arguments when it is invoked (<code>-x -v</code>);
+the SVR4.2 shell allows only one option argument (<code>-xv</code>).  In
+fact, some versions of the shell dump core if the second argument begins
+with a &lsquo;<samp>-</samp>&rsquo;.
+
+</li><li> The SVR4.2 shell exits a script if any builtin fails; Bash exits
+a script only if one of the <small>POSIX</small> special builtins fails, and
+only for certain failures, as enumerated in the <small>POSIX</small> standard.
+
+</li><li> The SVR4.2 shell behaves differently when invoked as <code>jsh</code>
+(it turns on job control).

+<li> PREAMBLE
+
+<p>The purpose of this License is to make a manual, textbook, or other
+functional and useful document <em>free</em> in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+</p>
+<p>This License is a kind of &ldquo;copyleft&rdquo;, which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+</p>
+<p>We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+</p>
+</li><li> APPLICABILITY AND DEFINITIONS
+
+<p>This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License.  Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein.  The &ldquo;Document&rdquo;, below,
+refers to any such manual or work.  Any member of the public is a
+licensee, and is addressed as &ldquo;you&rdquo;.  You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+</p>
+<p>A &ldquo;Modified Version&rdquo; of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+</p>
+<p>A &ldquo;Secondary Section&rdquo; is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document&rsquo;s overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject.  (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+</p>
+<p>The &ldquo;Invariant Sections&rdquo; are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.  If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant.  The Document may contain zero
+Invariant Sections.  If the Document does not identify any Invariant
+Sections then there are none.
+</p>
+<p>The &ldquo;Cover Texts&rdquo; are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.  A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+</p>
+<p>A &ldquo;Transparent&rdquo; copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text.  A copy that is not &ldquo;Transparent&rdquo; is called &ldquo;Opaque&rdquo;.
+</p>
+<p>Examples of suitable formats for Transparent copies include plain
+<small>ASCII</small> without markup, Texinfo input format, LaTeX input
+format, <acronym>SGML</acronym> or <acronym>XML</acronym> using a publicly available
+<acronym>DTD</acronym>, and standard-conforming simple <acronym>HTML</acronym>,
+PostScript or <acronym>PDF</acronym> designed for human modification.  Examples
+of transparent image formats include <acronym>PNG</acronym>, <acronym>XCF</acronym> and
+<acronym>JPG</acronym>.  Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, <acronym>SGML</acronym> or
+<acronym>XML</acronym> for which the <acronym>DTD</acronym> and/or processing tools are
+not generally available, and the machine-generated <acronym>HTML</acronym>,
+PostScript or <acronym>PDF</acronym> produced by some word processors for
+output purposes only.
+</p>
+<p>The &ldquo;Title Page&rdquo; means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, &ldquo;Title Page&rdquo; means
+the text near the most prominent appearance of the work&rsquo;s title,
+preceding the beginning of the body of the text.
+</p>
+<p>The &ldquo;publisher&rdquo; means any person or entity that distributes copies
+of the Document to the public.
+</p>
+<p>A section &ldquo;Entitled XYZ&rdquo; means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language.  (Here XYZ stands for a
+specific section name mentioned below, such as &ldquo;Acknowledgements&rdquo;,
+&ldquo;Dedications&rdquo;, &ldquo;Endorsements&rdquo;, or &ldquo;History&rdquo;.)  To &ldquo;Preserve the Title&rdquo;
+of such a section when you modify the Document means that it remains a
+section &ldquo;Entitled XYZ&rdquo; according to this definition.
+</p>
+<p>The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document.  These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+</p>
+</li><li> VERBATIM COPYING
+
+<p>You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License.  You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute.  However, you may accept
+compensation in exchange for copies.  If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+</p>
+<p>You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+</p>
+</li><li> COPYING IN QUANTITY
+
+<p>If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document&rsquo;s license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover.  Both covers must also clearly and legibly identify
+you as the publisher of these copies.  The front cover must present
+the full title with all words of the title equally prominent and
+visible.  You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+</p>
+<p>If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+</p>
+<p>If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+</p>
+<p>It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+</p>
+</li><li> MODIFICATIONS
+
+<p>You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it.  In addition, you must do these things in the Modified Version:
+</p>
+<ol type="A" start="1">
+<li> Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document).  You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+</li><li> List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+</li><li> State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+</li><li> Preserve all the copyright notices of the Document.
+
+</li><li> Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+</li><li> Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+</li><li> Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document&rsquo;s license notice.
+
+</li><li> Include an unaltered copy of this License.
+
+</li><li> Preserve the section Entitled &ldquo;History&rdquo;, Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page.  If
+there is no section Entitled &ldquo;History&rdquo; in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+</li><li> Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on.  These may be placed in the &ldquo;History&rdquo; section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+</li><li> For any section Entitled &ldquo;Acknowledgements&rdquo; or &ldquo;Dedications&rdquo;, Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+
+</li><li> Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles.  Section numbers
+or the equivalent are not considered part of the section titles.
+
+</li><li> Delete any section Entitled &ldquo;Endorsements&rdquo;.  Such a section
+may not be included in the Modified Version.
+
+</li><li> Do not retitle any existing section to be Entitled &ldquo;Endorsements&rdquo; or
+to conflict in title with any Invariant Section.
+
+</li><li> Preserve any Warranty Disclaimers.
+</li></ol>
+
+<p>If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant.  To do this, add their titles to the
+list of Invariant Sections in the Modified Version&rsquo;s license notice.
+These titles must be distinct from any other section titles.
+</p>
+<p>You may add a section Entitled &ldquo;Endorsements&rdquo;, provided it contains
+nothing but endorsements of your Modified Version by various
+parties&mdash;for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+</p>
+<p>You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version.  Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity.  If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+</p>
+<p>The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+</p>
+</li><li> COMBINING DOCUMENTS
+
+<p>You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+</p>
+<p>The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy.  If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+</p>
+<p>In the combination, you must combine any sections Entitled &ldquo;History&rdquo;
+in the various original documents, forming one section Entitled
+&ldquo;History&rdquo;; likewise combine any sections Entitled &ldquo;Acknowledgements&rdquo;,
+and any sections Entitled &ldquo;Dedications&rdquo;.  You must delete all
+sections Entitled &ldquo;Endorsements.&rdquo;
+</p>
+</li><li> COLLECTIONS OF DOCUMENTS
+
+<p>You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+</p>
+<p>You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+</p>
+</li><li> AGGREGATION WITH INDEPENDENT WORKS
+
+<p>A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an &ldquo;aggregate&rdquo; if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation&rsquo;s users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+</p>
+<p>If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document&rsquo;s Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+</p>
+</li><li> TRANSLATION
+
+<p>Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections.  You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers.  In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+</p>
+<p>If a section in the Document is Entitled &ldquo;Acknowledgements&rdquo;,
+&ldquo;Dedications&rdquo;, or &ldquo;History&rdquo;, the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+</p>
+</li><li> TERMINATION
+
+<p>You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+</p>
+<p>However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+</p>
+<p>Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+</p>
+<p>Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+</p>
+</li><li> FUTURE REVISIONS OF THIS LICENSE
+
+<p>The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time.  Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.  See
+<a href="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</a>.
+</p>
+<p>Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License &ldquo;or any later version&rdquo; applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation.  If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.  If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy&rsquo;s public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.
+</p>
+</li><li> RELICENSING
+
+<p>&ldquo;Massive Multiauthor Collaboration Site&rdquo; (or &ldquo;MMC Site&rdquo;) means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works.  A
+public wiki that anybody can edit is an example of such a server.  A
+&ldquo;Massive Multiauthor Collaboration&rdquo; (or &ldquo;MMC&rdquo;) contained in the
+site means any set of copyrightable works thus published on the MMC
+site.
+</p>
+<p>&ldquo;CC-BY-SA&rdquo; means the Creative Commons Attribution-Share Alike 3.0
+license published by Creative Commons Corporation, a not-for-profit
+corporation with a principal place of business in San Francisco,
+California, as well as future copyleft versions of that license
+published by that same organization.
+</p>
+<p>&ldquo;Incorporate&rdquo; means to publish or republish a Document, in whole or
+in part, as part of another Document.
+</p>
+<p>An MMC is &ldquo;eligible for relicensing&rdquo; if it is licensed under this
+License, and if all works that were first published under this License
+somewhere other than this MMC, and subsequently incorporated in whole
+or in part into the MMC, (1) had no cover texts or invariant sections,
+and (2) were thus incorporated prior to November 1, 2008.
+</p>
+<p>The operator of an MMC Site may republish an MMC contained in the site
+under CC-BY-SA on the same site at any time before August 1, 2009,
+provided the MMC is eligible for relicensing.

+<span id="ADDENDUM_003a-How-to-use-this-License-for-your-documents"></span><h3 class="heading">ADDENDUM: How to use this License for your documents</h3>
+
+<p>To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+</p>
+<div class="example">
+<pre class="example">  Copyright (C)  <var>year</var>  <var>your name</var>.
+  Permission is granted to copy, distribute and/or modify this document
+  under the terms of the GNU Free Documentation License, Version 1.3
+  or any later version published by the Free Software Foundation;
+  with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+  Texts.  A copy of the license is included in the section entitled ``GNU
+  Free Documentation License''.
+</pre></div>
+
+<p>If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the &ldquo;with&hellip;Texts.&rdquo; line with this:
+</p>
+<div class="example">
+<pre class="example">    with the Invariant Sections being <var>list their titles</var>, with
+    the Front-Cover Texts being <var>list</var>, and with the Back-Cover Texts
+    being <var>list</var>.
+</pre></div>
+
+<p>If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+</p>
+<p>If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

+
+1.1 What is Bash?
+=================
+
+Bash is the shell, or command language interpreter, for the GNU
+operating system.  The name is an acronym for the 'Bourne-Again SHell',
+a pun on Stephen Bourne, the author of the direct ancestor of the
+current Unix shell 'sh', which appeared in the Seventh Edition Bell Labs
+Research version of Unix.
+
+   Bash is largely compatible with 'sh' and incorporates useful features
+from the Korn shell 'ksh' and the C shell 'csh'.  It is intended to be a
+conformant implementation of the IEEE POSIX Shell and Tools portion of
+the IEEE POSIX specification (IEEE Standard 1003.1).  It offers
+functional improvements over 'sh' for both interactive and programming
+use.
+
+   While the GNU operating system provides other shells, including a
+version of 'csh', Bash is the default shell.  Like other GNU software,
+Bash is quite portable.  It currently runs on nearly every version of
+Unix and a few other operating systems - independently-supported ports
+exist for MS-DOS, OS/2, and Windows platforms.
+
+
+File: bashref.info,  Node: What is a shell?,  Prev: What is Bash?,  Up: Introduction
+
+1.2 What is a shell?
+====================
+
+At its base, a shell is simply a macro processor that executes commands.
+The term macro processor means functionality where text and symbols are
+expanded to create larger expressions.
+
+   A Unix shell is both a command interpreter and a programming
+language.  As a command interpreter, the shell provides the user
+interface to the rich set of GNU utilities.  The programming language
+features allow these utilities to be combined.  Files containing
+commands can be created, and become commands themselves.  These new
+commands have the same status as system commands in directories such as
+'/bin', allowing users or groups to establish custom environments to
+automate their common tasks.
+
+   Shells may be used interactively or non-interactively.  In
+interactive mode, they accept input typed from the keyboard.  When
+executing non-interactively, shells execute commands read from a file.
+
+   A shell allows execution of GNU commands, both synchronously and
+asynchronously.  The shell waits for synchronous commands to complete
+before accepting more input; asynchronous commands continue to execute
+in parallel with the shell while it reads and executes additional
+commands.  The "redirection" constructs permit fine-grained control of
+the input and output of those commands.  Moreover, the shell allows
+control over the contents of commands' environments.
+
+   Shells also provide a small set of built-in commands ("builtins")
+implementing functionality impossible or inconvenient to obtain via
+separate utilities.  For example, 'cd', 'break', 'continue', and 'exec'
+cannot be implemented outside of the shell because they directly
+manipulate the shell itself.  The 'history', 'getopts', 'kill', or 'pwd'
+builtins, among others, could be implemented in separate utilities, but
+they are more convenient to use as builtin commands.  All of the shell
+builtins are described in subsequent sections.
+
+   While executing commands is essential, most of the power (and
+complexity) of shells is due to their embedded programming languages.
+Like any high-level language, the shell provides variables, flow control
+constructs, quoting, and functions.
+
+   Shells offer features geared specifically for interactive use rather
+than to augment the programming language.  These interactive features
+include job control, command line editing, command history and aliases.
+Each of these features is described in this manual.

+
+2 Definitions
+*************
+
+These definitions are used throughout the remainder of this manual.
+
+'POSIX'
+     A family of open system standards based on Unix.  Bash is primarily
+     concerned with the Shell and Utilities portion of the POSIX 1003.1
+     standard.
+
+'blank'
+     A space or tab character.
+
+'builtin'
+     A command that is implemented internally by the shell itself,
+     rather than by an executable program somewhere in the file system.
+
+'control operator'
+     A 'token' that performs a control function.  It is a 'newline' or
+     one of the following: '||', '&&', '&', ';', ';;', ';&', ';;&', '|',
+     '|&', '(', or ')'.
+
+'exit status'
+     The value returned by a command to its caller.  The value is
+     restricted to eight bits, so the maximum value is 255.
+
+'field'
+     A unit of text that is the result of one of the shell expansions.
+     After expansion, when executing a command, the resulting fields are
+     used as the command name and arguments.
+
+'filename'
+     A string of characters used to identify a file.
+
+'job'
+     A set of processes comprising a pipeline, and any processes
+     descended from it, that are all in the same process group.
+
+'job control'
+     A mechanism by which users can selectively stop (suspend) and
+     restart (resume) execution of processes.
+
+'metacharacter'
+     A character that, when unquoted, separates words.  A metacharacter
+     is a 'space', 'tab', 'newline', or one of the following characters:
+     '|', '&', ';', '(', ')', '<', or '>'.
+
+'name'
+     A 'word' consisting solely of letters, numbers, and underscores,
+     and beginning with a letter or underscore.  'Name's are used as
+     shell variable and function names.  Also referred to as an
+     'identifier'.
+
+'operator'
+     A 'control operator' or a 'redirection operator'.  *Note
+     Redirections::, for a list of redirection operators.  Operators
+     contain at least one unquoted 'metacharacter'.
+
+'process group'
+     A collection of related processes each having the same process
+     group ID.
+
+'process group ID'
+     A unique identifier that represents a 'process group' during its
+     lifetime.
+
+'reserved word'
+     A 'word' that has a special meaning to the shell.  Most reserved
+     words introduce shell flow control constructs, such as 'for' and
+     'while'.
+
+'return status'
+     A synonym for 'exit status'.
+
+'signal'
+     A mechanism by which a process may be notified by the kernel of an
+     event occurring in the system.
+
+'special builtin'
+     A shell builtin command that has been classified as special by the
+     POSIX standard.
+
+'token'
+     A sequence of characters considered a single unit by the shell.  It
+     is either a 'word' or an 'operator'.
+
+'word'
+     A sequence of characters treated as a unit by the shell.  Words may
+     not include unquoted 'metacharacters'.

+
+3 Basic Shell Features
+**********************
+
+Bash is an acronym for 'Bourne-Again SHell'.  The Bourne shell is the
+traditional Unix shell originally written by Stephen Bourne.  All of the
+Bourne shell builtin commands are available in Bash, The rules for
+evaluation and quoting are taken from the POSIX specification for the
+'standard' Unix shell.
+
+   This chapter briefly summarizes the shell's 'building blocks':
+commands, control structures, shell functions, shell parameters, shell
+expansions, redirections, which are a way to direct input and output
+from and to named files, and how the shell executes commands.

+================
+
+* Menu:
+
+* Shell Operation::	The basic operation of the shell.
+* Quoting::		How to remove the special meaning from characters.
+* Comments::		How to specify comments.
+
+When the shell reads input, it proceeds through a sequence of
+operations.  If the input indicates the beginning of a comment, the
+shell ignores the comment symbol ('#'), and the rest of that line.
+
+   Otherwise, roughly speaking, the shell reads its input and divides
+the input into words and operators, employing the quoting rules to
+select which meanings to assign various words and characters.
+
+   The shell then parses these tokens into commands and other
+constructs, removes the special meaning of certain words or characters,
+expands others, redirects input and output as needed, executes the
+specified command, waits for the command's exit status, and makes that
+exit status available for further inspection or processing.
+
+
+File: bashref.info,  Node: Shell Operation,  Next: Quoting,  Up: Shell Syntax
+
+3.1.1 Shell Operation
+---------------------
+
+The following is a brief description of the shell's operation when it
+reads and executes a command.  Basically, the shell does the following:
+
+  1. Reads its input from a file (*note Shell Scripts::), from a string
+     supplied as an argument to the '-c' invocation option (*note
+     Invoking Bash::), or from the user's terminal.
+
+  2. Breaks the input into words and operators, obeying the quoting
+     rules described in *note Quoting::.  These tokens are separated by
+     'metacharacters'.  Alias expansion is performed by this step (*note
+     Aliases::).
+
+  3. Parses the tokens into simple and compound commands (*note Shell
+     Commands::).
+
+  4. Performs the various shell expansions (*note Shell Expansions::),
+     breaking the expanded tokens into lists of filenames (*note
+     Filename Expansion::) and commands and arguments.
+
+  5. Performs any necessary redirections (*note Redirections::) and
+     removes the redirection operators and their operands from the
+     argument list.
+
+  6. Executes the command (*note Executing Commands::).
+
+  7. Optionally waits for the command to complete and collects its exit
+     status (*note Exit Status::).

+
+3.1.2 Quoting
+-------------
+
+* Menu:
+
+* Escape Character::	How to remove the special meaning from a single
+			character.
+* Single Quotes::	How to inhibit all interpretation of a sequence
+			of characters.
+* Double Quotes::	How to suppress most of the interpretation of a
+			sequence of characters.
+* ANSI-C Quoting::	How to expand ANSI-C sequences in quoted strings.
+* Locale Translation::	How to translate strings into different languages.
+
+Quoting is used to remove the special meaning of certain characters or
+words to the shell.  Quoting can be used to disable special treatment
+for special characters, to prevent reserved words from being recognized
+as such, and to prevent parameter expansion.
+
+   Each of the shell metacharacters (*note Definitions::) has special
+meaning to the shell and must be quoted if it is to represent itself.
+When the command history expansion facilities are being used (*note
+History Interaction::), the "history expansion" character, usually '!',
+must be quoted to prevent history expansion.  *Note Bash History
+Facilities::, for more details concerning history expansion.
+
+   There are three quoting mechanisms: the "escape character", single
+quotes, and double quotes.
+
+
+File: bashref.info,  Node: Escape Character,  Next: Single Quotes,  Up: Quoting
+
+3.1.2.1 Escape Character
+........................
+
+A non-quoted backslash '\' is the Bash escape character.  It preserves
+the literal value of the next character that follows, with the exception
+of 'newline'.  If a '\newline' pair appears, and the backslash itself is
+not quoted, the '\newline' is treated as a line continuation (that is,
+it is removed from the input stream and effectively ignored).
+
+
+File: bashref.info,  Node: Single Quotes,  Next: Double Quotes,  Prev: Escape Character,  Up: Quoting
+
+3.1.2.2 Single Quotes
+.....................
+
+Enclosing characters in single quotes (''') preserves the literal value
+of each character within the quotes.  A single quote may not occur
+between single quotes, even when preceded by a backslash.
+
+
+File: bashref.info,  Node: Double Quotes,  Next: ANSI-C Quoting,  Prev: Single Quotes,  Up: Quoting
+
+3.1.2.3 Double Quotes
+.....................
+
+Enclosing characters in double quotes ('"') preserves the literal value
+of all characters within the quotes, with the exception of '$', '`',
+'\', and, when history expansion is enabled, '!'.  When the shell is in
+POSIX mode (*note Bash POSIX Mode::), the '!' has no special meaning
+within double quotes, even when history expansion is enabled.  The
+characters '$' and '`' retain their special meaning within double quotes
+(*note Shell Expansions::).  The backslash retains its special meaning
+only when followed by one of the following characters: '$', '`', '"',
+'\', or 'newline'.  Within double quotes, backslashes that are followed
+by one of these characters are removed.  Backslashes preceding
+characters without a special meaning are left unmodified.  A double
+quote may be quoted within double quotes by preceding it with a
+backslash.  If enabled, history expansion will be performed unless an
+'!' appearing in double quotes is escaped using a backslash.  The
+backslash preceding the '!' is not removed.
+
+   The special parameters '*' and '@' have special meaning when in
+double quotes (*note Shell Parameter Expansion::).
+
+
+File: bashref.info,  Node: ANSI-C Quoting,  Next: Locale Translation,  Prev: Double Quotes,  Up: Quoting
+
+3.1.2.4 ANSI-C Quoting
+......................
+
+Character sequences of the form $'STRING' are treated as a special kind
+of single quotes.  The sequence expands to STRING, with
+backslash-escaped characters in STRING replaced as specified by the ANSI
+C standard.  Backslash escape sequences, if present, are decoded as
+follows:
+
+'\a'
+     alert (bell)
+'\b'
+     backspace
+'\e'
+'\E'
+     an escape character (not ANSI C)
+'\f'
+     form feed
+'\n'
+     newline
+'\r'
+     carriage return
+'\t'
+     horizontal tab
+'\v'
+     vertical tab
+'\\'
+     backslash
+'\''
+     single quote
+'\"'
+     double quote
+'\?'
+     question mark
+'\NNN'
+     the eight-bit character whose value is the octal value NNN (one to
+     three octal digits)
+'\xHH'
+     the eight-bit character whose value is the hexadecimal value HH
+     (one or two hex digits)
+'\uHHHH'
+     the Unicode (ISO/IEC 10646) character whose value is the
+     hexadecimal value HHHH (one to four hex digits)
+'\UHHHHHHHH'
+     the Unicode (ISO/IEC 10646) character whose value is the
+     hexadecimal value HHHHHHHH (one to eight hex digits)
+'\cX'
+     a control-X character
+
+The expanded result is single-quoted, as if the dollar sign had not been
+present.
+
+
+File: bashref.info,  Node: Locale Translation,  Prev: ANSI-C Quoting,  Up: Quoting
+
+3.1.2.5 Locale-Specific Translation
+...................................
+
+* Menu:
+
+* Creating Internationalized Scripts::	How to use translations and different
+					languages in your scripts.
+
+Prefixing a double-quoted string with a dollar sign ('$'), such as
+$"hello, world", will cause the string to be translated according to the
+current locale.  The 'gettext' infrastructure performs the lookup and
+translation, using the 'LC_MESSAGES', 'TEXTDOMAINDIR', and 'TEXTDOMAIN'
+shell variables, as explained below.  See the gettext documentation for
+additional details not covered here.  If the current locale is 'C' or
+'POSIX', if there are no translations available, of if the string is not
+translated, the dollar sign is ignored.  Since this is a form of double
+quoting, the string remains double-quoted by default, whether or not it
+is translated and replaced.  If the 'noexpand_translation' option is
+enabled using the 'shopt' builtin (*note The Shopt Builtin::),
+translated strings are single-quoted instead of double-quoted.

+   The rest of this section is a brief overview of how you use gettext
+to create translations for strings in a shell script named SCRIPTNAME.
+There are more details in the gettext documentation.
+
+
+File: bashref.info,  Node: Creating Internationalized Scripts,  Up: Locale Translation
+
+Once you've marked the strings in your script that you want to translate
+using $"...", you create a gettext "template" file using the command
+
+     bash --dump-po-strings SCRIPTNAME > DOMAIN.pot
+
+The DOMAIN is your "message domain".  It's just an arbitrary string
+that's used to identify the files gettext needs, like a package or
+script name.  It needs to be unique among all the message domains on
+systems where you install the translations, so gettext knows which
+translations correspond to your script.  You'll use the template file to
+create translations for each target language.  The template file
+conventionally has the suffix '.pot'.
+
+   You copy this template file to a separate file for each target
+language you want to support (called "PO" files, which use the suffix
+'.po').  PO files use various naming conventions, but when you are
+working to translate a template file into a particular language, you
+first copy the template file to a file whose name is the language you
+want to target, with the '.po' suffix.  For instance, the Spanish
+translations of your strings would be in a file named 'es.po', and to
+get started using a message domain named "example," you would run
+
+     cp example.pot es.po
+
+Ultimately, PO files are often named DOMAIN.po and installed in
+directories that contain multiple translation files for a particular
+language.
+
+   Whichever naming convention you choose, you will need to translate
+the strings in the PO files into the appropriate languages.  This has to
+be done manually.
+
+   When you have the translations and PO files complete, you'll use the
+gettext tools to produce what are called "MO" files, which are compiled
+versions of the PO files the gettext tools use to look up translations
+efficiently.  MO files are also called "message catalog" files.  You use
+the 'msgfmt' program to do this.  For instance, if you had a file with
+Spanish translations, you could run
+
+     msgfmt -o es.mo es.po
+
+to produce the corresponding MO file.
+
+   Once you have the MO files, you decide where to install them and use
+the 'TEXTDOMAINDIR' shell variable to tell the gettext tools where they
+are.  Make sure to use the same message domain to name the MO files as
+you did for the PO files when you install them.
+
+   Your users will use the 'LANG' or 'LC_MESSAGES' shell variables to
+select the desired language.
+
+   You set the 'TEXTDOMAIN' variable to the script's message domain.  As
+above, you use the message domain to name your translation files.
+
+   You, or possibly your users, set the 'TEXTDOMAINDIR' variable to the
+name of a directory where the message catalog files are stored.  If you
+install the message files into the system's standard message catalog
+directory, you don't need to worry about this variable.
+
+   The directory where the message catalog files are stored varies
+between systems.  Some use the message catalog selected by the
+'LC_MESSAGES' shell variable.  Others create the name of the message
+catalog from the value of the 'TEXTDOMAIN' shell variable, possibly
+adding the '.mo' suffix.  If you use the 'TEXTDOMAIN' variable, you may
+need to set the 'TEXTDOMAINDIR' variable to the location of the message
+catalog files, as above.  It's common to use both variables in this
+fashion: '$TEXTDOMAINDIR'/'$LC_MESSAGES'/LC_MESSAGES/'$TEXTDOMAIN'.mo.
+
+   If you used that last convention, and you wanted to store the message
+catalog files with Spanish (es) and Esperanto (eo) translations into a
+local directory you use for custom translation files, you could run
+
+     TEXTDOMAIN=example
+     TEXTDOMAINDIR=/usr/local/share/locale
+
+     cp es.mo ${TEXTDOMAINDIR}/es/LC_MESSAGES/${TEXTDOMAIN}.mo
+     cp eo.mo ${TEXTDOMAINDIR}/eo/LC_MESSAGES/${TEXTDOMAIN}.mo
+
+   When all of this is done, and the message catalog files containing
+the compiled translations are installed in the correct location, your
+users will be able to see translated strings in any of the supported
+languages by setting the 'LANG' or 'LC_MESSAGES' environment variables
+before running your script.

+3.2 Shell Commands
+==================
+
+A simple shell command such as 'echo a b c' consists of the command
+itself followed by arguments, separated by spaces.
+
+   More complex shell commands are composed of simple commands arranged
+together in a variety of ways: in a pipeline in which the output of one
+command becomes the input of a second, in a loop or conditional
+construct, or in some other grouping.

+
+3.2.1 Reserved Words
+--------------------
+
+Reserved words are words that have special meaning to the shell.  They
+are used to begin and end the shell's compound commands.
+
+   The following words are recognized as reserved when unquoted and the
+first word of a command (see below for exceptions):
+
+'if'    'then'  'elif'  'else'  'fi'      'time'
+'for'   'in'    'until' 'while' 'do'      'done'
+'case'  'esac'  'coproc''select''function'
+'{'     '}'     '[['    ']]'    '!'
+
+'in' is recognized as a reserved word if it is the third word of a
+'case' or 'select' command.  'in' and 'do' are recognized as reserved
+words if they are the third word in a 'for' command.
+
+
+File: bashref.info,  Node: Simple Commands,  Next: Pipelines,  Prev: Reserved Words,  Up: Shell Commands
+
+3.2.2 Simple Commands
+---------------------
+
+A simple command is the kind of command encountered most often.  It's
+just a sequence of words separated by 'blank's, terminated by one of the
+shell's control operators (*note Definitions::).  The first word
+generally specifies a command to be executed, with the rest of the words
+being that command's arguments.
+
+   The return status (*note Exit Status::) of a simple command is its
+exit status as provided by the POSIX 1003.1 'waitpid' function, or 128+N
+if the command was terminated by signal N.
+
+
+File: bashref.info,  Node: Pipelines,  Next: Lists,  Prev: Simple Commands,  Up: Shell Commands
+
+3.2.3 Pipelines
+---------------
+
+A 'pipeline' is a sequence of one or more commands separated by one of
+the control operators '|' or '|&'.
+
+   The format for a pipeline is
+     [time [-p]] [!] COMMAND1 [ | or |& COMMAND2 ] ...
+
+The output of each command in the pipeline is connected via a pipe to
+the input of the next command.  That is, each command reads the previous
+command's output.  This connection is performed before any redirections
+specified by COMMAND1.
+
+   If '|&' is used, COMMAND1's standard error, in addition to its
+standard output, is connected to COMMAND2's standard input through the
+pipe; it is shorthand for '2>&1 |'.  This implicit redirection of the
+standard error to the standard output is performed after any
+redirections specified by COMMAND1.
+
+   The reserved word 'time' causes timing statistics to be printed for
+the pipeline once it finishes.  The statistics currently consist of
+elapsed (wall-clock) time and user and system time consumed by the
+command's execution.  The '-p' option changes the output format to that
+specified by POSIX.  When the shell is in POSIX mode (*note Bash POSIX
+Mode::), it does not recognize 'time' as a reserved word if the next
+token begins with a '-'.  The 'TIMEFORMAT' variable may be set to a
+format string that specifies how the timing information should be
+displayed.  *Note Bash Variables::, for a description of the available
+formats.  The use of 'time' as a reserved word permits the timing of
+shell builtins, shell functions, and pipelines.  An external 'time'
+command cannot time these easily.
+
+   When the shell is in POSIX mode (*note Bash POSIX Mode::), 'time' may
+be followed by a newline.  In this case, the shell displays the total
+user and system time consumed by the shell and its children.  The
+'TIMEFORMAT' variable may be used to specify the format of the time
+information.
+
+   If the pipeline is not executed asynchronously (*note Lists::), the
+shell waits for all commands in the pipeline to complete.
+
+   Each command in a multi-command pipeline, where pipes are created, is
+executed in its own "subshell", which is a separate process (*note
+Command Execution Environment::).  If the 'lastpipe' option is enabled
+using the 'shopt' builtin (*note The Shopt Builtin::), the last element
+of a pipeline may be run by the shell process when job control is not
+active.
+
+   The exit status of a pipeline is the exit status of the last command
+in the pipeline, unless the 'pipefail' option is enabled (*note The Set
+Builtin::).  If 'pipefail' is enabled, the pipeline's return status is
+the value of the last (rightmost) command to exit with a non-zero
+status, or zero if all commands exit successfully.  If the reserved word
+'!' precedes the pipeline, the exit status is the logical negation of
+the exit status as described above.  The shell waits for all commands in
+the pipeline to terminate before returning a value.
+
+
+File: bashref.info,  Node: Lists,  Next: Compound Commands,  Prev: Pipelines,  Up: Shell Commands
+
+3.2.4 Lists of Commands
+-----------------------
+
+A 'list' is a sequence of one or more pipelines separated by one of the
+operators ';', '&', '&&', or '||', and optionally terminated by one of
+';', '&', or a 'newline'.
+
+   Of these list operators, '&&' and '||' have equal precedence,
+followed by ';' and '&', which have equal precedence.
+
+   A sequence of one or more newlines may appear in a 'list' to delimit
+commands, equivalent to a semicolon.
+
+   If a command is terminated by the control operator '&', the shell
+executes the command asynchronously in a subshell.  This is known as
+executing the command in the "background", and these are referred to as
+"asynchronous" commands.  The shell does not wait for the command to
+finish, and the return status is 0 (true).  When job control is not
+active (*note Job Control::), the standard input for asynchronous
+commands, in the absence of any explicit redirections, is redirected
+from '/dev/null'.
+
+   Commands separated by a ';' are executed sequentially; the shell
+waits for each command to terminate in turn.  The return status is the
+exit status of the last command executed.
+
+   AND and OR lists are sequences of one or more pipelines separated by
+the control operators '&&' and '||', respectively.  AND and OR lists are
+executed with left associativity.
+
+   An AND list has the form
+     COMMAND1 && COMMAND2
+
+COMMAND2 is executed if, and only if, COMMAND1 returns an exit status of
+zero (success).
+
+   An OR list has the form
+     COMMAND1 || COMMAND2
+
+COMMAND2 is executed if, and only if, COMMAND1 returns a non-zero exit
+status.
+
+   The return status of AND and OR lists is the exit status of the last
+command executed in the list.

+-----------------------
+
+* Menu:
+
+* Looping Constructs::		Shell commands for iterative action.
+* Conditional Constructs::	Shell commands for conditional execution.
+* Command Grouping::		Ways to group commands.
+
+Compound commands are the shell programming language constructs.  Each
+construct begins with a reserved word or control operator and is
+terminated by a corresponding reserved word or operator.  Any
+redirections (*note Redirections::) associated with a compound command
+apply to all commands within that compound command unless explicitly
+overridden.
+
+   In most cases a list of commands in a compound command's description
+may be separated from the rest of the command by one or more newlines,
+and may be followed by a newline in place of a semicolon.
+
+   Bash provides looping constructs, conditional commands, and
+mechanisms to group commands and execute them as a unit.
+
+
+File: bashref.info,  Node: Looping Constructs,  Next: Conditional Constructs,  Up: Compound Commands
+
+3.2.5.1 Looping Constructs
+..........................
+
+Bash supports the following looping constructs.
+
+   Note that wherever a ';' appears in the description of a command's
+syntax, it may be replaced with one or more newlines.
+
+'until'
+     The syntax of the 'until' command is:
+
+          until TEST-COMMANDS; do CONSEQUENT-COMMANDS; done
+
+     Execute CONSEQUENT-COMMANDS as long as TEST-COMMANDS has an exit
+     status which is not zero.  The return status is the exit status of
+     the last command executed in CONSEQUENT-COMMANDS, or zero if none
+     was executed.
+
+'while'
+     The syntax of the 'while' command is:
+
+          while TEST-COMMANDS; do CONSEQUENT-COMMANDS; done
+
+     Execute CONSEQUENT-COMMANDS as long as TEST-COMMANDS has an exit
+     status of zero.  The return status is the exit status of the last
+     command executed in CONSEQUENT-COMMANDS, or zero if none was
+     executed.
+
+'for'
+     The syntax of the 'for' command is:
+
+          for NAME [ [in [WORDS ...] ] ; ] do COMMANDS; done
+
+     Expand WORDS (*note Shell Expansions::), and execute COMMANDS once
+     for each member in the resultant list, with NAME bound to the
+     current member.  If 'in WORDS' is not present, the 'for' command
+     executes the COMMANDS once for each positional parameter that is
+     set, as if 'in "$@"' had been specified (*note Special
+     Parameters::).
+
+     The return status is the exit status of the last command that
+     executes.  If there are no items in the expansion of WORDS, no
+     commands are executed, and the return status is zero.
+
+     An alternate form of the 'for' command is also supported:
+
+          for (( EXPR1 ; EXPR2 ; EXPR3 )) ; do COMMANDS ; done
+
+     First, the arithmetic expression EXPR1 is evaluated according to
+     the rules described below (*note Shell Arithmetic::).  The
+     arithmetic expression EXPR2 is then evaluated repeatedly until it
+     evaluates to zero.  Each time EXPR2 evaluates to a non-zero value,
+     COMMANDS are executed and the arithmetic expression EXPR3 is
+     evaluated.  If any expression is omitted, it behaves as if it
+     evaluates to 1.  The return value is the exit status of the last
+     command in COMMANDS that is executed, or false if any of the
+     expressions is invalid.
+
+   The 'break' and 'continue' builtins (*note Bourne Shell Builtins::)
+may be used to control loop execution.
+
+
+File: bashref.info,  Node: Conditional Constructs,  Next: Command Grouping,  Prev: Looping Constructs,  Up: Compound Commands
+
+3.2.5.2 Conditional Constructs
+..............................
+
+'if'
+     The syntax of the 'if' command is:
+
+          if TEST-COMMANDS; then
+            CONSEQUENT-COMMANDS;
+          [elif MORE-TEST-COMMANDS; then
+            MORE-CONSEQUENTS;]
+          [else ALTERNATE-CONSEQUENTS;]
+          fi
+
+     The TEST-COMMANDS list is executed, and if its return status is
+     zero, the CONSEQUENT-COMMANDS list is executed.  If TEST-COMMANDS
+     returns a non-zero status, each 'elif' list is executed in turn,
+     and if its exit status is zero, the corresponding MORE-CONSEQUENTS
+     is executed and the command completes.  If 'else
+     ALTERNATE-CONSEQUENTS' is present, and the final command in the
+     final 'if' or 'elif' clause has a non-zero exit status, then
+     ALTERNATE-CONSEQUENTS is executed.  The return status is the exit
+     status of the last command executed, or zero if no condition tested
+     true.
+
+'case'
+     The syntax of the 'case' command is:
+
+          case WORD in
+              [ [(] PATTERN [| PATTERN]...) COMMAND-LIST ;;]...
+          esac
+
+     'case' will selectively execute the COMMAND-LIST corresponding to
+     the first PATTERN that matches WORD.  The match is performed
+     according to the rules described below in *note Pattern Matching::.
+     If the 'nocasematch' shell option (see the description of 'shopt'
+     in *note The Shopt Builtin::) is enabled, the match is performed
+     without regard to the case of alphabetic characters.  The '|' is
+     used to separate multiple patterns, and the ')' operator terminates
+     a pattern list.  A list of patterns and an associated command-list
+     is known as a CLAUSE.
+
+     Each clause must be terminated with ';;', ';&', or ';;&'.  The WORD
+     undergoes tilde expansion, parameter expansion, command
+     substitution, arithmetic expansion, and quote removal (*note Shell
+     Parameter Expansion::) before matching is attempted.  Each PATTERN
+     undergoes tilde expansion, parameter expansion, command
+     substitution, arithmetic expansion, process substitution, and quote
+     removal.
+
+     There may be an arbitrary number of 'case' clauses, each terminated
+     by a ';;', ';&', or ';;&'.  The first pattern that matches
+     determines the command-list that is executed.  It's a common idiom
+     to use '*' as the final pattern to define the default case, since
+     that pattern will always match.
+
+     Here is an example using 'case' in a script that could be used to
+     describe one interesting feature of an animal:
+
+          echo -n "Enter the name of an animal: "
+          read ANIMAL
+          echo -n "The $ANIMAL has "
+          case $ANIMAL in
+            horse | dog | cat) echo -n "four";;
+            man | kangaroo ) echo -n "two";;
+            *) echo -n "an unknown number of";;
+          esac
+          echo " legs."
+
+
+     If the ';;' operator is used, no subsequent matches are attempted
+     after the first pattern match.  Using ';&' in place of ';;' causes
+     execution to continue with the COMMAND-LIST associated with the
+     next clause, if any.  Using ';;&' in place of ';;' causes the shell
+     to test the patterns in the next clause, if any, and execute any
+     associated COMMAND-LIST on a successful match, continuing the case
+     statement execution as if the pattern list had not matched.
+
+     The return status is zero if no PATTERN is matched.  Otherwise, the
+     return status is the exit status of the COMMAND-LIST executed.
+
+'select'
+
+     The 'select' construct allows the easy generation of menus.  It has
+     almost the same syntax as the 'for' command:
+
+          select NAME [in WORDS ...]; do COMMANDS; done
+
+     The list of words following 'in' is expanded, generating a list of
+     items, and the set of expanded words is printed on the standard
+     error output stream, each preceded by a number.  If the 'in WORDS'
+     is omitted, the positional parameters are printed, as if 'in "$@"'
+     had been specified.  'select' then displays the 'PS3' prompt and
+     reads a line from the standard input.  If the line consists of a
+     number corresponding to one of the displayed words, then the value
+     of NAME is set to that word.  If the line is empty, the words and
+     prompt are displayed again.  If 'EOF' is read, the 'select' command
+     completes and returns 1.  Any other value read causes NAME to be
+     set to null.  The line read is saved in the variable 'REPLY'.
+
+     The COMMANDS are executed after each selection until a 'break'
+     command is executed, at which point the 'select' command completes.
+
+     Here is an example that allows the user to pick a filename from the
+     current directory, and displays the name and index of the file
+     selected.
+
+          select fname in *;
+          do
+          	echo you picked $fname \($REPLY\)
+          	break;
+          done
+
+'((...))'
+          (( EXPRESSION ))
+
+     The arithmetic EXPRESSION is evaluated according to the rules
+     described below (*note Shell Arithmetic::).  The EXPRESSION
+     undergoes the same expansions as if it were within double quotes,
+     but double quote characters in EXPRESSION are not treated specially
+     are removed.  If the value of the expression is non-zero, the
+     return status is 0; otherwise the return status is 1.
+
+'[[...]]'
+          [[ EXPRESSION ]]
+
+     Return a status of 0 or 1 depending on the evaluation of the
+     conditional expression EXPRESSION.  Expressions are composed of the
+     primaries described below in *note Bash Conditional Expressions::.
+     The words between the '[[' and ']]' do not undergo word splitting
+     and filename expansion.  The shell performs tilde expansion,
+     parameter and variable expansion, arithmetic expansion, command
+     substitution, process substitution, and quote removal on those
+     words (the expansions that would occur if the words were enclosed
+     in double quotes).  Conditional operators such as '-f' must be
+     unquoted to be recognized as primaries.
+
+     When used with '[[', the '<' and '>' operators sort
+     lexicographically using the current locale.
+
+     When the '==' and '!=' operators are used, the string to the right
+     of the operator is considered a pattern and matched according to
+     the rules described below in *note Pattern Matching::, as if the
+     'extglob' shell option were enabled.  The '=' operator is identical
+     to '=='.  If the 'nocasematch' shell option (see the description of
+     'shopt' in *note The Shopt Builtin::) is enabled, the match is
+     performed without regard to the case of alphabetic characters.  The
+     return value is 0 if the string matches ('==') or does not match
+     ('!=') the pattern, and 1 otherwise.
+
+     If you quote any part of the pattern, using any of the shell's
+     quoting mechanisms, the quoted portion is matched literally.  This
+     means every character in the quoted portion matches itself, instead
+     of having any special pattern matching meaning.
+
+     An additional binary operator, '=~', is available, with the same
+     precedence as '==' and '!='.  When you use '=~', the string to the
+     right of the operator is considered a POSIX extended regular
+     expression pattern and matched accordingly (using the POSIX
+     'regcomp' and 'regexec' interfaces usually described in regex(3)).
+     The return value is 0 if the string matches the pattern, and 1 if
+     it does not.  If the regular expression is syntactically incorrect,
+     the conditional expression returns 2.  If the 'nocasematch' shell
+     option (see the description of 'shopt' in *note The Shopt
+     Builtin::) is enabled, the match is performed without regard to the
+     case of alphabetic characters.
+
+     You can quote any part of the pattern to force the quoted portion
+     to be matched literally instead of as a regular expression (see
+     above).  If the pattern is stored in a shell variable, quoting the
+     variable expansion forces the entire pattern to be matched
+     literally.
+
+     The pattern will match if it matches any part of the string.  If
+     you want to force the pattern to match the entire string, anchor
+     the pattern using the '^' and '$' regular expression operators.
+
+     For example, the following will match a line (stored in the shell
+     variable 'line') if there is a sequence of characters anywhere in
+     the value consisting of any number, including zero, of characters
+     in the 'space' character class, immediately followed by zero or one
+     instances of 'a', then a 'b':
+
+          [[ $line =~ [[:space:]]*(a)?b ]]
+
+     That means values for 'line' like 'aab', ' aaaaaab', 'xaby', and '
+     ab' will all match, as will a line containing a 'b' anywhere in its
+     value.
+
+     If you want to match a character that's special to the regular
+     expression grammar ('^$|[]()\.*+?'), it has to be quoted to remove
+     its special meaning.  This means that in the pattern 'xxx.txt', the
+     '.' matches any character in the string (its usual regular
+     expression meaning), but in the pattern '"xxx.txt"', it can only
+     match a literal '.'.
+
+     Likewise, if you want to include a character in your pattern that
+     has a special meaning to the regular expression grammar, you must
+     make sure it's not quoted.  If you want to anchor a pattern at the
+     beginning or end of the string, for instance, you cannot quote the
+     '^' or '$' characters using any form of shell quoting.
+
+     If you want to match 'initial string' at the start of a line, the
+     following will work:
+          [[ $line =~ ^"initial string" ]]
+     but this will not:
+          [[ $line =~ "^initial string" ]]
+     because in the second example the '^' is quoted and doesn't have
+     its usual special meaning.
+
+     It is sometimes difficult to specify a regular expression properly
+     without using quotes, or to keep track of the quoting used by
+     regular expressions while paying attention to shell quoting and the
+     shell's quote removal.  Storing the regular expression in a shell
+     variable is often a useful way to avoid problems with quoting
+     characters that are special to the shell.  For example, the
+     following is equivalent to the pattern used above:
+
+          pattern='[[:space:]]*(a)?b'
+          [[ $line =~ $pattern ]]
+
+     Shell programmers should take special care with backslashes, since
+     backslashes are used by both the shell and regular expressions to
+     remove the special meaning from the following character.  This
+     means that after the shell's word expansions complete (*note Shell
+     Expansions::), any backslashes remaining in parts of the pattern
+     that were originally not quoted can remove the special meaning of
+     pattern characters.  If any part of the pattern is quoted, the
+     shell does its best to ensure that the regular expression treats
+     those remaining backslashes as literal, if they appeared in a
+     quoted portion.
+
+     The following two sets of commands are _not_ equivalent:
+
+          pattern='\.'
+
+          [[ . =~ $pattern ]]
+          [[ . =~ \. ]]
+
+          [[ . =~ "$pattern" ]]
+          [[ . =~ '\.' ]]
+
+     The first two matches will succeed, but the second two will not,
+     because in the second two the backslash will be part of the pattern
+     to be matched.  In the first two examples, the pattern passed to
+     the regular expression parser is '\.'.  The backslash removes the
+     special meaning from '.', so the literal '.' matches.  In the
+     second two examples, the pattern passed to the regular expression
+     parser has the backslash quoted (e.g., '\\\.'), which will not
+     match the string, since it does not contain a backslash.  If the
+     string in the first examples were anything other than '.', say 'a',
+     the pattern would not match, because the quoted '.' in the pattern
+     loses its special meaning of matching any single character.
+
+     Bracket expressions in regular expressions can be sources of errors
+     as well, since characters that are normally special in regular
+     expressions lose their special meanings between brackets.  However,
+     you can use bracket expressions to match special pattern characters
+     without quoting them, so they are sometimes useful for this
+     purpose.
+
+     Though it might seem like a strange way to write it, the following
+     pattern will match a '.' in the string:
+
+          [[ . =~ [.] ]]
+
+     The shell performs any word expansions before passing the pattern
+     to the regular expression functions, so you can assume that the
+     shell's quoting takes precedence.  As noted above, the regular
+     expression parser will interpret any unquoted backslashes remaining
+     in the pattern after shell expansion according to its own rules.
+     The intention is to avoid making shell programmers quote things
+     twice as much as possible, so shell quoting should be sufficient to
+     quote special pattern characters where that's necessary.
+
+     The array variable 'BASH_REMATCH' records which parts of the string
+     matched the pattern.  The element of 'BASH_REMATCH' with index 0
+     contains the portion of the string matching the entire regular
+     expression.  Substrings matched by parenthesized subexpressions
+     within the regular expression are saved in the remaining
+     'BASH_REMATCH' indices.  The element of 'BASH_REMATCH' with index N
+     is the portion of the string matching the Nth parenthesized
+     subexpression.
+
+     Bash sets 'BASH_REMATCH' in the global scope; declaring it as a
+     local variable will lead to unexpected results.
+
+     Expressions may be combined using the following operators, listed
+     in decreasing order of precedence:
+
+     '( EXPRESSION )'
+          Returns the value of EXPRESSION.  This may be used to override
+          the normal precedence of operators.
+
+     '! EXPRESSION'
+          True if EXPRESSION is false.
+
+     'EXPRESSION1 && EXPRESSION2'
+          True if both EXPRESSION1 and EXPRESSION2 are true.
+
+     'EXPRESSION1 || EXPRESSION2'
+          True if either EXPRESSION1 or EXPRESSION2 is true.
+
+     The '&&' and '||' operators do not evaluate EXPRESSION2 if the
+     value of EXPRESSION1 is sufficient to determine the return value of
+     the entire conditional expression.

+3.2.5.3 Grouping Commands
+.........................
+
+Bash provides two ways to group a list of commands to be executed as a
+unit.  When commands are grouped, redirections may be applied to the
+entire command list.  For example, the output of all the commands in the
+list may be redirected to a single stream.
+
+'()'
+          ( LIST )
+
+     Placing a list of commands between parentheses forces the shell to
+     create a subshell (*note Command Execution Environment::), and each
+     of the commands in LIST is executed in that subshell environment.
+     Since the LIST is executed in a subshell, variable assignments do
+     not remain in effect after the subshell completes.
+
+'{}'
+          { LIST; }
+
+     Placing a list of commands between curly braces causes the list to
+     be executed in the current shell context.  No subshell is created.
+     The semicolon (or newline) following LIST is required.
+
+   In addition to the creation of a subshell, there is a subtle
+difference between these two constructs due to historical reasons.  The
+braces are reserved words, so they must be separated from the LIST by
+'blank's or other shell metacharacters.  The parentheses are operators,
+and are recognized as separate tokens by the shell even if they are not
+separated from the LIST by whitespace.
+
+   The exit status of both of these constructs is the exit status of
+LIST.

+
+File: bashref.info,  Node: Coprocesses,  Next: GNU Parallel,  Prev: Compound Commands,  Up: Shell Commands
+
+3.2.6 Coprocesses
+-----------------
+
+A 'coprocess' is a shell command preceded by the 'coproc' reserved word.
+A coprocess is executed asynchronously in a subshell, as if the command
+had been terminated with the '&' control operator, with a two-way pipe
+established between the executing shell and the coprocess.
+
+   The syntax for a coprocess is:
+
+     coproc [NAME] COMMAND [REDIRECTIONS]
+
+This creates a coprocess named NAME.  COMMAND may be either a simple
+command (*note Simple Commands::) or a compound command (*note Compound
+Commands::).  NAME is a shell variable name.  If NAME is not supplied,
+the default name is 'COPROC'.
+
+   The recommended form to use for a coprocess is
+
+     coproc NAME { COMMAND; }
+
+This form is recommended because simple commands result in the coprocess
+always being named 'COPROC', and it is simpler to use and more complete
+than the other compound commands.
+
+   There are other forms of coprocesses:
+
+     coproc NAME COMPOUND-COMMAND
+     coproc COMPOUND-COMMAND
+     coproc SIMPLE-COMMAND
+
+If COMMAND is a compound command, NAME is optional.  The word following
+'coproc' determines whether that word is interpreted as a variable name:
+it is interpreted as NAME if it is not a reserved word that introduces a
+compound command.  If COMMAND is a simple command, NAME is not allowed;
+this is to avoid confusion between NAME and the first word of the simple
+command.
+
+   When the coprocess is executed, the shell creates an array variable
+(*note Arrays::) named NAME in the context of the executing shell.  The
+standard output of COMMAND is connected via a pipe to a file descriptor
+in the executing shell, and that file descriptor is assigned to NAME[0].
+The standard input of COMMAND is connected via a pipe to a file
+descriptor in the executing shell, and that file descriptor is assigned
+to NAME[1].  This pipe is established before any redirections specified
+by the command (*note Redirections::).  The file descriptors can be
+utilized as arguments to shell commands and redirections using standard
+word expansions.  Other than those created to execute command and
+process substitutions, the file descriptors are not available in
+subshells.
+
+   The process ID of the shell spawned to execute the coprocess is
+available as the value of the variable 'NAME_PID'.  The 'wait' builtin
+command may be used to wait for the coprocess to terminate.
+
+   Since the coprocess is created as an asynchronous command, the
+'coproc' command always returns success.  The return status of a
+coprocess is the exit status of COMMAND.

+3.2.7 GNU Parallel
+------------------
+
+There are ways to run commands in parallel that are not built into Bash.
+GNU Parallel is a tool to do just that.
+
+   GNU Parallel, as its name suggests, can be used to build and run
+commands in parallel.  You may run the same command with different
+arguments, whether they are filenames, usernames, hostnames, or lines
+read from files.  GNU Parallel provides shorthand references to many of
+the most common operations (input lines, various portions of the input
+line, different ways to specify the input source, and so on).  Parallel
+can replace 'xargs' or feed commands from its input sources to several
+different instances of Bash.
+
+   For a complete description, refer to the GNU Parallel documentation,
+which is available at
+<https://www.gnu.org/software/parallel/parallel_tutorial.html>.

+File: bashref.info,  Node: Shell Functions,  Next: Shell Parameters,  Prev: Shell Commands,  Up: Basic Shell Features
+
+3.3 Shell Functions
+===================
+
+Shell functions are a way to group commands for later execution using a
+single name for the group.  They are executed just like a "regular"
+command.  When the name of a shell function is used as a simple command
+name, the list of commands associated with that function name is
+executed.  Shell functions are executed in the current shell context; no
+new process is created to interpret them.
+
+   Functions are declared using this syntax:
+     FNAME () COMPOUND-COMMAND [ REDIRECTIONS ]
+
+   or
+
+     function FNAME [()] COMPOUND-COMMAND [ REDIRECTIONS ]
+
+   This defines a shell function named FNAME.  The reserved word
+'function' is optional.  If the 'function' reserved word is supplied,
+the parentheses are optional.  The "body" of the function is the
+compound command COMPOUND-COMMAND (*note Compound Commands::).  That
+command is usually a LIST enclosed between { and }, but may be any
+compound command listed above.  If the 'function' reserved word is used,
+but the parentheses are not supplied, the braces are recommended.
+COMPOUND-COMMAND is executed whenever FNAME is specified as the name of
+a simple command.  When the shell is in POSIX mode (*note Bash POSIX
+Mode::), FNAME must be a valid shell name and may not be the same as one
+of the special builtins (*note Special Builtins::).  In default mode, a
+function name can be any unquoted shell word that does not contain '$'.
+Any redirections (*note Redirections::) associated with the shell
+function are performed when the function is executed.  A function
+definition may be deleted using the '-f' option to the 'unset' builtin
+(*note Bourne Shell Builtins::).
+
+   The exit status of a function definition is zero unless a syntax
+error occurs or a readonly function with the same name already exists.
+When executed, the exit status of a function is the exit status of the
+last command executed in the body.
+
+   Note that for historical reasons, in the most common usage the curly
+braces that surround the body of the function must be separated from the
+body by 'blank's or newlines.  This is because the braces are reserved
+words and are only recognized as such when they are separated from the
+command list by whitespace or another shell metacharacter.  Also, when
+using the braces, the LIST must be terminated by a semicolon, a '&', or
+a newline.
+
+   When a function is executed, the arguments to the function become the
+positional parameters during its execution (*note Positional
+Parameters::).  The special parameter '#' that expands to the number of
+positional parameters is updated to reflect the change.  Special
+parameter '0' is unchanged.  The first element of the 'FUNCNAME'
+variable is set to the name of the function while the function is
+executing.
+
+   All other aspects of the shell execution environment are identical
+between a function and its caller with these exceptions: the 'DEBUG' and
+'RETURN' traps are not inherited unless the function has been given the
+'trace' attribute using the 'declare' builtin or the '-o functrace'
+option has been enabled with the 'set' builtin, (in which case all
+functions inherit the 'DEBUG' and 'RETURN' traps), and the 'ERR' trap is
+not inherited unless the '-o errtrace' shell option has been enabled.
+*Note Bourne Shell Builtins::, for the description of the 'trap'
+builtin.
+
+   The 'FUNCNEST' variable, if set to a numeric value greater than 0,
+defines a maximum function nesting level.  Function invocations that
+exceed the limit cause the entire command to abort.
+
+   If the builtin command 'return' is executed in a function, the
+function completes and execution resumes with the next command after the
+function call.  Any command associated with the 'RETURN' trap is
+executed before execution resumes.  When a function completes, the
+values of the positional parameters and the special parameter '#' are
+restored to the values they had prior to the function's execution.  If a
+numeric argument is given to 'return', that is the function's return
+status; otherwise the function's return status is the exit status of the
+last command executed before the 'return'.
+
+   Variables local to the function may be declared with the 'local'
+builtin ("local variables").  Ordinarily, variables and their values are
+shared between a function and its caller.  These variables are visible
+only to the function and the commands it invokes.  This is particularly
+important when a shell function calls other functions.
+
+   In the following description, the "current scope" is a currently-
+executing function.  Previous scopes consist of that function's caller
+and so on, back to the "global" scope, where the shell is not executing
+any shell function.  Consequently, a local variable at the current local
+scope is a variable declared using the 'local' or 'declare' builtins in
+the function that is currently executing.
+
+   Local variables "shadow" variables with the same name declared at
+previous scopes.  For instance, a local variable declared in a function
+hides a global variable of the same name: references and assignments
+refer to the local variable, leaving the global variable unmodified.
+When the function returns, the global variable is once again visible.
+
+   The shell uses "dynamic scoping" to control a variable's visibility
+within functions.  With dynamic scoping, visible variables and their
+values are a result of the sequence of function calls that caused
+execution to reach the current function.  The value of a variable that a
+function sees depends on its value within its caller, if any, whether
+that caller is the "global" scope or another shell function.  This is
+also the value that a local variable declaration "shadows", and the
+value that is restored when the function returns.
+
+   For example, if a variable 'var' is declared as local in function
+'func1', and 'func1' calls another function 'func2', references to 'var'
+made from within 'func2' will resolve to the local variable 'var' from
+'func1', shadowing any global variable named 'var'.
+
+   The following script demonstrates this behavior.  When executed, the
+script displays
+
+     In func2, var = func1 local
+
+     func1()
+     {
+         local var='func1 local'
+         func2
+     }
+
+     func2()
+     {
+         echo "In func2, var = $var"
+     }
+
+     var=global
+     func1
+
+   The 'unset' builtin also acts using the same dynamic scope: if a
+variable is local to the current scope, 'unset' will unset it; otherwise
+the unset will refer to the variable found in any calling scope as
+described above.  If a variable at the current local scope is unset, it
+will remain so (appearing as unset) until it is reset in that scope or
+until the function returns.  Once the function returns, any instance of
+the variable at a previous scope will become visible.  If the unset acts
+on a variable at a previous scope, any instance of a variable with that
+name that had been shadowed will become visible (see below how
+'localvar_unset'shell option changes this behavior).
+
+   Function names and definitions may be listed with the '-f' option to
+the 'declare' ('typeset') builtin command (*note Bash Builtins::).  The
+'-F' option to 'declare' or 'typeset' will list the function names only
+(and optionally the source file and line number, if the 'extdebug' shell
+option is enabled).  Functions may be exported so that child shell
+processes (those created when executing a separate shell invocation)
+automatically have them defined with the '-f' option to the 'export'
+builtin (*note Bourne Shell Builtins::).
+
+   Functions may be recursive.  The 'FUNCNEST' variable may be used to
+limit the depth of the function call stack and restrict the number of
+function invocations.  By default, no limit is placed on the number of
+recursive calls.

+
+3.4 Shell Parameters
+====================
+
+* Menu:
+
+* Positional Parameters::	The shell's command-line arguments.
+* Special Parameters::		Parameters denoted by special characters.
+
+A "parameter" is an entity that stores values.  It can be a 'name', a
+number, or one of the special characters listed below.  A "variable" is
+a parameter denoted by a 'name'.  A variable has a 'value' and zero or
+more 'attributes'.  Attributes are assigned using the 'declare' builtin
+command (see the description of the 'declare' builtin in *note Bash
+Builtins::).
+
+   A parameter is set if it has been assigned a value.  The null string
+is a valid value.  Once a variable is set, it may be unset only by using
+the 'unset' builtin command.
+
+   A variable may be assigned to by a statement of the form
+     NAME=[VALUE]
+If VALUE is not given, the variable is assigned the null string.  All
+VALUEs undergo tilde expansion, parameter and variable expansion,
+command substitution, arithmetic expansion, and quote removal (*note
+Shell Parameter Expansion::).  If the variable has its 'integer'
+attribute set, then VALUE is evaluated as an arithmetic expression even
+if the '$((...))' expansion is not used (*note Arithmetic Expansion::).
+Word splitting and filename expansion are not performed.  Assignment
+statements may also appear as arguments to the 'alias', 'declare',
+'typeset', 'export', 'readonly', and 'local' builtin commands
+("declaration" commands).  When in POSIX mode (*note Bash POSIX Mode::),
+these builtins may appear in a command after one or more instances of
+the 'command' builtin and retain these assignment statement properties.
+
+   In the context where an assignment statement is assigning a value to
+a shell variable or array index (*note Arrays::), the '+=' operator can
+be used to append to or add to the variable's previous value.  This
+includes arguments to builtin commands such as 'declare' that accept
+assignment statements (declaration commands).  When '+=' is applied to a
+variable for which the 'integer' attribute has been set, VALUE is
+evaluated as an arithmetic expression and added to the variable's
+current value, which is also evaluated.  When '+=' is applied to an
+array variable using compound assignment (*note Arrays::), the
+variable's value is not unset (as it is when using '='), and new values
+are appended to the array beginning at one greater than the array's
+maximum index (for indexed arrays), or added as additional key-value
+pairs in an associative array.  When applied to a string-valued
+variable, VALUE is expanded and appended to the variable's value.
+
+   A variable can be assigned the 'nameref' attribute using the '-n'
+option to the 'declare' or 'local' builtin commands (*note Bash
+Builtins::) to create a "nameref", or a reference to another variable.
+This allows variables to be manipulated indirectly.  Whenever the
+nameref variable is referenced, assigned to, unset, or has its
+attributes modified (other than using or changing the nameref attribute
+itself), the operation is actually performed on the variable specified
+by the nameref variable's value.  A nameref is commonly used within
+shell functions to refer to a variable whose name is passed as an
+argument to the function.  For instance, if a variable name is passed to
+a shell function as its first argument, running
+     declare -n ref=$1
+inside the function creates a nameref variable 'ref' whose value is the
+variable name passed as the first argument.  References and assignments
+to 'ref', and changes to its attributes, are treated as references,
+assignments, and attribute modifications to the variable whose name was
+passed as '$1'.
+
+   If the control variable in a 'for' loop has the nameref attribute,
+the list of words can be a list of shell variables, and a name reference
+will be established for each word in the list, in turn, when the loop is
+executed.  Array variables cannot be given the nameref attribute.
+However, nameref variables can reference array variables and subscripted
+array variables.  Namerefs can be unset using the '-n' option to the
+'unset' builtin (*note Bourne Shell Builtins::).  Otherwise, if 'unset'
+is executed with the name of a nameref variable as an argument, the
+variable referenced by the nameref variable will be unset.
+
+
+File: bashref.info,  Node: Positional Parameters,  Next: Special Parameters,  Up: Shell Parameters
+
+3.4.1 Positional Parameters
+---------------------------
+
+A "positional parameter" is a parameter denoted by one or more digits,
+other than the single digit '0'.  Positional parameters are assigned
+from the shell's arguments when it is invoked, and may be reassigned
+using the 'set' builtin command.  Positional parameter 'N' may be
+referenced as '${N}', or as '$N' when 'N' consists of a single digit.
+Positional parameters may not be assigned to with assignment statements.
+The 'set' and 'shift' builtins are used to set and unset them (*note
+Shell Builtin Commands::).  The positional parameters are temporarily
+replaced when a shell function is executed (*note Shell Functions::).
+
+   When a positional parameter consisting of more than a single digit is
+expanded, it must be enclosed in braces.
+
+
+File: bashref.info,  Node: Special Parameters,  Prev: Positional Parameters,  Up: Shell Parameters
+
+3.4.2 Special Parameters
+------------------------
+
+The shell treats several parameters specially.  These parameters may
+only be referenced; assignment to them is not allowed.
+
+'*'
+     ($*) Expands to the positional parameters, starting from one.  When
+     the expansion is not within double quotes, each positional
+     parameter expands to a separate word.  In contexts where it is
+     performed, those words are subject to further word splitting and
+     filename expansion.  When the expansion occurs within double
+     quotes, it expands to a single word with the value of each
+     parameter separated by the first character of the 'IFS' special
+     variable.  That is, '"$*"' is equivalent to '"$1C$2C..."', where C
+     is the first character of the value of the 'IFS' variable.  If
+     'IFS' is unset, the parameters are separated by spaces.  If 'IFS'
+     is null, the parameters are joined without intervening separators.
+
+'@'
+     ($@) Expands to the positional parameters, starting from one.  In
+     contexts where word splitting is performed, this expands each
+     positional parameter to a separate word; if not within double
+     quotes, these words are subject to word splitting.  In contexts
+     where word splitting is not performed, this expands to a single
+     word with each positional parameter separated by a space.  When the
+     expansion occurs within double quotes, and word splitting is
+     performed, each parameter expands to a separate word.  That is,
+     '"$@"' is equivalent to '"$1" "$2" ...'.  If the double-quoted
+     expansion occurs within a word, the expansion of the first
+     parameter is joined with the beginning part of the original word,
+     and the expansion of the last parameter is joined with the last
+     part of the original word.  When there are no positional
+     parameters, '"$@"' and '$@' expand to nothing (i.e., they are
+     removed).
+
+'#'
+     ($#) Expands to the number of positional parameters in decimal.
+
+'?'
+     ($?)  Expands to the exit status of the most recently executed
+     foreground pipeline.
+
+'-'
+     ($-, a hyphen.)  Expands to the current option flags as specified
+     upon invocation, by the 'set' builtin command, or those set by the
+     shell itself (such as the '-i' option).
+
+'$'
+     ($$) Expands to the process ID of the shell.  In a subshell, it
+     expands to the process ID of the invoking shell, not the subshell.
+
+'!'
+     ($!)  Expands to the process ID of the job most recently placed
+     into the background, whether executed as an asynchronous command or
+     using the 'bg' builtin (*note Job Control Builtins::).
+
+'0'
+     ($0) Expands to the name of the shell or shell script.  This is set
+     at shell initialization.  If Bash is invoked with a file of
+     commands (*note Shell Scripts::), '$0' is set to the name of that
+     file.  If Bash is started with the '-c' option (*note Invoking
+     Bash::), then '$0' is set to the first argument after the string to
+     be executed, if one is present.  Otherwise, it is set to the
+     filename used to invoke Bash, as given by argument zero.

+("quote removal").

+
+3.5.1 Brace Expansion
+---------------------
+
+Brace expansion is a mechanism by which arbitrary strings may be
+generated.  This mechanism is similar to "filename expansion" (*note
+Filename Expansion::), but the filenames generated need not exist.
+Patterns to be brace expanded take the form of an optional PREAMBLE,
+followed by either a series of comma-separated strings or a sequence
+expression between a pair of braces, followed by an optional POSTSCRIPT.
+The preamble is prefixed to each string contained within the braces, and
+the postscript is then appended to each resulting string, expanding left
+to right.
+
+   Brace expansions may be nested.  The results of each expanded string
+are not sorted; left to right order is preserved.  For example,
+     bash$ echo a{d,c,b}e
+     ade ace abe
+
+   A sequence expression takes the form '{X..Y[..INCR]}', where X and Y
+are either integers or letters, and INCR, an optional increment, is an
+integer.  When integers are supplied, the expression expands to each
+number between X and Y, inclusive.  Supplied integers may be prefixed
+with '0' to force each term to have the same width.  When either X or Y
+begins with a zero, the shell attempts to force all generated terms to
+contain the same number of digits, zero-padding where necessary.  When
+letters are supplied, the expression expands to each character
+lexicographically between X and Y, inclusive, using the default C
+locale.  Note that both X and Y must be of the same type (integer or
+letter).  When the increment is supplied, it is used as the difference
+between each term.  The default increment is 1 or -1 as appropriate.
+
+   Brace expansion is performed before any other expansions, and any
+characters special to other expansions are preserved in the result.  It
+is strictly textual.  Bash does not apply any syntactic interpretation
+to the context of the expansion or the text between the braces.
+
+   A correctly-formed brace expansion must contain unquoted opening and
+closing braces, and at least one unquoted comma or a valid sequence
+expression.  Any incorrectly formed brace expansion is left unchanged.
+
+   A { or ',' may be quoted with a backslash to prevent its being
+considered part of a brace expression.  To avoid conflicts with
+parameter expansion, the string '${' is not considered eligible for
+brace expansion, and inhibits brace expansion until the closing '}'.
+
+   This construct is typically used as shorthand when the common prefix
+of the strings to be generated is longer than in the above example:
+     mkdir /usr/local/src/bash/{old,new,dist,bugs}
+   or
+     chown root /usr/{ucb/{ex,edit},lib/{ex?.?*,how_ex}}

+
+3.5.2 Tilde Expansion
+---------------------
+
+If a word begins with an unquoted tilde character ('~'), all of the
+characters up to the first unquoted slash (or all characters, if there
+is no unquoted slash) are considered a "tilde-prefix".  If none of the
+characters in the tilde-prefix are quoted, the characters in the
+tilde-prefix following the tilde are treated as a possible "login name".
+If this login name is the null string, the tilde is replaced with the
+value of the 'HOME' shell variable.  If 'HOME' is unset, the home
+directory of the user executing the shell is substituted instead.
+Otherwise, the tilde-prefix is replaced with the home directory
+associated with the specified login name.
+
+   If the tilde-prefix is '~+', the value of the shell variable 'PWD'
+replaces the tilde-prefix.  If the tilde-prefix is '~-', the value of
+the shell variable 'OLDPWD', if it is set, is substituted.
+
+   If the characters following the tilde in the tilde-prefix consist of
+a number N, optionally prefixed by a '+' or a '-', the tilde-prefix is
+replaced with the corresponding element from the directory stack, as it
+would be displayed by the 'dirs' builtin invoked with the characters
+following tilde in the tilde-prefix as an argument (*note The Directory
+Stack::).  If the tilde-prefix, sans the tilde, consists of a number
+without a leading '+' or '-', '+' is assumed.
+
+   If the login name is invalid, or the tilde expansion fails, the word
+is left unchanged.
+
+   Each variable assignment is checked for unquoted tilde-prefixes
+immediately following a ':' or the first '='.  In these cases, tilde
+expansion is also performed.  Consequently, one may use filenames with
+tildes in assignments to 'PATH', 'MAILPATH', and 'CDPATH', and the shell
+assigns the expanded value.
+
+   The following table shows how Bash treats unquoted tilde-prefixes:
+
+'~'
+     The value of '$HOME'
+'~/foo'
+     '$HOME/foo'
+
+'~fred/foo'
+     The subdirectory 'foo' of the home directory of the user 'fred'
+
+'~+/foo'
+     '$PWD/foo'
+
+'~-/foo'
+     '${OLDPWD-'~-'}/foo'
+
+'~N'
+     The string that would be displayed by 'dirs +N'
+
+'~+N'
+     The string that would be displayed by 'dirs +N'
+
+'~-N'
+     The string that would be displayed by 'dirs -N'
+
+   Bash also performs tilde expansion on words satisfying the conditions
+of variable assignments (*note Shell Parameters::) when they appear as
+arguments to simple commands.  Bash does not do this, except for the
+declaration commands listed above, when in POSIX mode.
+
+
+File: bashref.info,  Node: Shell Parameter Expansion,  Next: Command Substitution,  Prev: Tilde Expansion,  Up: Shell Expansions
+
+3.5.3 Shell Parameter Expansion
+-------------------------------
+
+The '$' character introduces parameter expansion, command substitution,
+or arithmetic expansion.  The parameter name or symbol to be expanded
+may be enclosed in braces, which are optional but serve to protect the
+variable to be expanded from characters immediately following it which
+could be interpreted as part of the name.
+
+   When braces are used, the matching ending brace is the first '}' not
+escaped by a backslash or within a quoted string, and not within an
+embedded arithmetic expansion, command substitution, or parameter
+expansion.
+
+   The basic form of parameter expansion is ${PARAMETER}.  The value of
+PARAMETER is substituted.  The PARAMETER is a shell parameter as
+described above (*note Shell Parameters::) or an array reference (*note
+Arrays::).  The braces are required when PARAMETER is a positional
+parameter with more than one digit, or when PARAMETER is followed by a
+character that is not to be interpreted as part of its name.
+
+   If the first character of PARAMETER is an exclamation point (!), and
+PARAMETER is not a nameref, it introduces a level of indirection.  Bash
+uses the value formed by expanding the rest of PARAMETER as the new
+PARAMETER; this is then expanded and that value is used in the rest of
+the expansion, rather than the expansion of the original PARAMETER.
+This is known as 'indirect expansion'.  The value is subject to tilde
+expansion, parameter expansion, command substitution, and arithmetic
+expansion.  If PARAMETER is a nameref, this expands to the name of the
+variable referenced by PARAMETER instead of performing the complete
+indirect expansion.  The exceptions to this are the expansions of
+${!PREFIX*} and ${!NAME[@]} described below.  The exclamation point must
+immediately follow the left brace in order to introduce indirection.
+
+   In each of the cases below, WORD is subject to tilde expansion,
+parameter expansion, command substitution, and arithmetic expansion.
+
+   When not performing substring expansion, using the form described
+below (e.g., ':-'), Bash tests for a parameter that is unset or null.
+Omitting the colon results in a test only for a parameter that is unset.
+Put another way, if the colon is included, the operator tests for both
+PARAMETER's existence and that its value is not null; if the colon is
+omitted, the operator tests only for existence.
+
+'${PARAMETER:-WORD}'
+     If PARAMETER is unset or null, the expansion of WORD is
+     substituted.  Otherwise, the value of PARAMETER is substituted.
+
+          $ v=123
+          $ echo ${v-unset}
+          123
+
+'${PARAMETER:=WORD}'
+     If PARAMETER is unset or null, the expansion of WORD is assigned to
+     PARAMETER.  The value of PARAMETER is then substituted.  Positional
+     parameters and special parameters may not be assigned to in this
+     way.
+
+          $ var=
+          $ : ${var:=DEFAULT}
+          $ echo $var
+          DEFAULT
+
+'${PARAMETER:?WORD}'
+     If PARAMETER is null or unset, the expansion of WORD (or a message
+     to that effect if WORD is not present) is written to the standard
+     error and the shell, if it is not interactive, exits.  Otherwise,
+     the value of PARAMETER is substituted.
+
+          $ var=
+          $ : ${var:?var is unset or null}
+          bash: var: var is unset or null
+
+'${PARAMETER:+WORD}'
+     If PARAMETER is null or unset, nothing is substituted, otherwise
+     the expansion of WORD is substituted.
+
+          $ var=123
+          $ echo ${var:+var is set and not null}
+          var is set and not null
+
+'${PARAMETER:OFFSET}'
+'${PARAMETER:OFFSET:LENGTH}'
+     This is referred to as Substring Expansion.  It expands to up to
+     LENGTH characters of the value of PARAMETER starting at the
+     character specified by OFFSET.  If PARAMETER is '@' or '*', an
+     indexed array subscripted by '@' or '*', or an associative array
+     name, the results differ as described below.  If LENGTH is omitted,
+     it expands to the substring of the value of PARAMETER starting at
+     the character specified by OFFSET and extending to the end of the
+     value.  LENGTH and OFFSET are arithmetic expressions (*note Shell
+     Arithmetic::).
+
+     If OFFSET evaluates to a number less than zero, the value is used
+     as an offset in characters from the end of the value of PARAMETER.
+     If LENGTH evaluates to a number less than zero, it is interpreted
+     as an offset in characters from the end of the value of PARAMETER
+     rather than a number of characters, and the expansion is the
+     characters between OFFSET and that result.  Note that a negative
+     offset must be separated from the colon by at least one space to
+     avoid being confused with the ':-' expansion.
+
+     Here are some examples illustrating substring expansion on
+     parameters and subscripted arrays:
+
+     $ string=01234567890abcdefgh
+     $ echo ${string:7}
+     7890abcdefgh
+     $ echo ${string:7:0}
+     
+     $ echo ${string:7:2}
+     78
+     $ echo ${string:7:-2}
+     7890abcdef
+     $ echo ${string: -7}
+     bcdefgh
+     $ echo ${string: -7:0}
+     
+     $ echo ${string: -7:2}
+     bc
+     $ echo ${string: -7:-2}
+     bcdef
+     $ set -- 01234567890abcdefgh
+     $ echo ${1:7}
+     7890abcdefgh
+     $ echo ${1:7:0}
+     
+     $ echo ${1:7:2}
+     78
+     $ echo ${1:7:-2}
+     7890abcdef
+     $ echo ${1: -7}
+     bcdefgh
+     $ echo ${1: -7:0}
+     
+     $ echo ${1: -7:2}
+     bc
+     $ echo ${1: -7:-2}
+     bcdef
+     $ array[0]=01234567890abcdefgh
+     $ echo ${array[0]:7}
+     7890abcdefgh
+     $ echo ${array[0]:7:0}
+     
+     $ echo ${array[0]:7:2}
+     78
+     $ echo ${array[0]:7:-2}
+     7890abcdef
+     $ echo ${array[0]: -7}
+     bcdefgh
+     $ echo ${array[0]: -7:0}
+     
+     $ echo ${array[0]: -7:2}
+     bc
+     $ echo ${array[0]: -7:-2}
+     bcdef
+
+     If PARAMETER is '@' or '*', the result is LENGTH positional
+     parameters beginning at OFFSET.  A negative OFFSET is taken
+     relative to one greater than the greatest positional parameter, so
+     an offset of -1 evaluates to the last positional parameter.  It is
+     an expansion error if LENGTH evaluates to a number less than zero.
+
+     The following examples illustrate substring expansion using
+     positional parameters:
+
+     $ set -- 1 2 3 4 5 6 7 8 9 0 a b c d e f g h
+     $ echo ${@:7}
+     7 8 9 0 a b c d e f g h
+     $ echo ${@:7:0}
+     
+     $ echo ${@:7:2}
+     7 8
+     $ echo ${@:7:-2}
+     bash: -2: substring expression < 0
+     $ echo ${@: -7:2}
+     b c
+     $ echo ${@:0}
+     ./bash 1 2 3 4 5 6 7 8 9 0 a b c d e f g h
+     $ echo ${@:0:2}
+     ./bash 1
+     $ echo ${@: -7:0}
+     
+
+     If PARAMETER is an indexed array name subscripted by '@' or '*',
+     the result is the LENGTH members of the array beginning with
+     '${PARAMETER[OFFSET]}'.  A negative OFFSET is taken relative to one
+     greater than the maximum index of the specified array.  It is an
+     expansion error if LENGTH evaluates to a number less than zero.
+
+     These examples show how you can use substring expansion with
+     indexed arrays:
+
+     $ array=(0 1 2 3 4 5 6 7 8 9 0 a b c d e f g h)
+     $ echo ${array[@]:7}
+     7 8 9 0 a b c d e f g h
+     $ echo ${array[@]:7:2}
+     7 8
+     $ echo ${array[@]: -7:2}
+     b c
+     $ echo ${array[@]: -7:-2}
+     bash: -2: substring expression < 0
+     $ echo ${array[@]:0}
+     0 1 2 3 4 5 6 7 8 9 0 a b c d e f g h
+     $ echo ${array[@]:0:2}
+     0 1
+     $ echo ${array[@]: -7:0}
+     
+
+     Substring expansion applied to an associative array produces
+     undefined results.
+
+     Substring indexing is zero-based unless the positional parameters
+     are used, in which case the indexing starts at 1 by default.  If
+     OFFSET is 0, and the positional parameters are used, '$0' is
+     prefixed to the list.
+
+'${!PREFIX*}'
+'${!PREFIX@}'
+     Expands to the names of variables whose names begin with PREFIX,
+     separated by the first character of the 'IFS' special variable.
+     When '@' is used and the expansion appears within double quotes,
+     each variable name expands to a separate word.
+
+'${!NAME[@]}'
+'${!NAME[*]}'
+     If NAME is an array variable, expands to the list of array indices
+     (keys) assigned in NAME.  If NAME is not an array, expands to 0 if
+     NAME is set and null otherwise.  When '@' is used and the expansion
+     appears within double quotes, each key expands to a separate word.
+
+'${#PARAMETER}'
+     The length in characters of the expanded value of PARAMETER is
+     substituted.  If PARAMETER is '*' or '@', the value substituted is
+     the number of positional parameters.  If PARAMETER is an array name
+     subscripted by '*' or '@', the value substituted is the number of
+     elements in the array.  If PARAMETER is an indexed array name
+     subscripted by a negative number, that number is interpreted as
+     relative to one greater than the maximum index of PARAMETER, so
+     negative indices count back from the end of the array, and an index
+     of -1 references the last element.
+
+'${PARAMETER#WORD}'
+'${PARAMETER##WORD}'
+     The WORD is expanded to produce a pattern and matched according to
+     the rules described below (*note Pattern Matching::).  If the
+     pattern matches the beginning of the expanded value of PARAMETER,
+     then the result of the expansion is the expanded value of PARAMETER
+     with the shortest matching pattern (the '#' case) or the longest
+     matching pattern (the '##' case) deleted.  If PARAMETER is '@' or
+     '*', the pattern removal operation is applied to each positional
+     parameter in turn, and the expansion is the resultant list.  If
+     PARAMETER is an array variable subscripted with '@' or '*', the
+     pattern removal operation is applied to each member of the array in
+     turn, and the expansion is the resultant list.
+
+'${PARAMETER%WORD}'
+'${PARAMETER%%WORD}'
+     The WORD is expanded to produce a pattern and matched according to
+     the rules described below (*note Pattern Matching::).  If the
+     pattern matches a trailing portion of the expanded value of
+     PARAMETER, then the result of the expansion is the value of
+     PARAMETER with the shortest matching pattern (the '%' case) or the
+     longest matching pattern (the '%%' case) deleted.  If PARAMETER is
+     '@' or '*', the pattern removal operation is applied to each
+     positional parameter in turn, and the expansion is the resultant
+     list.  If PARAMETER is an array variable subscripted with '@' or
+     '*', the pattern removal operation is applied to each member of the
+     array in turn, and the expansion is the resultant list.
+
+'${PARAMETER/PATTERN/STRING}'
+'${PARAMETER//PATTERN/STRING}'
+'${PARAMETER/#PATTERN/STRING}'
+'${PARAMETER/%PATTERN/STRING}'
+     The PATTERN is expanded to produce a pattern just as in filename
+     expansion.  PARAMETER is expanded and the longest match of PATTERN
+     against its value is replaced with STRING.  STRING undergoes tilde
+     expansion, parameter and variable expansion, arithmetic expansion,
+     command and process substitution, and quote removal.  The match is
+     performed according to the rules described below (*note Pattern
+     Matching::).
+
+     In the first form above, only the first match is replaced.  If
+     there are two slashes separating PARAMETER and PATTERN (the second
+     form above), all matches of PATTERN are replaced with STRING.  If
+     PATTERN is preceded by '#' (the third form above), it must match at
+     the beginning of the expanded value of PARAMETER.  If PATTERN is
+     preceded by '%' (the fourth form above), it must match at the end
+     of the expanded value of PARAMETER.  If the expansion of STRING is
+     null, matches of PATTERN are deleted.  If STRING is null, matches
+     of PATTERN are deleted and the '/' following PATTERN may be
+     omitted.
+
+     If the 'patsub_replacement' shell option is enabled using 'shopt',
+     any unquoted instances of '&' in STRING are replaced with the
+     matching portion of PATTERN.  This is intended to duplicate a
+     common 'sed' idiom.
+
+     Quoting any part of STRING inhibits replacement in the expansion of
+     the quoted portion, including replacement strings stored in shell
+     variables.  Backslash will escape '&' in STRING; the backslash is
+     removed in order to permit a literal '&' in the replacement string.
+     Users should take care if STRING is double-quoted to avoid unwanted
+     interactions between the backslash and double-quoting, since
+     backslash has special meaning within double quotes.  Pattern
+     substitution performs the check for unquoted '&' after expanding
+     STRING, so users should ensure to properly quote any occurrences of
+     '&' they want to be taken literally in the replacement and ensure
+     any instances of '&' they want to be replaced are unquoted.
+
+     For instance,
+
+          var=abcdef
+          rep='& '
+          echo ${var/abc/& }
+          echo "${var/abc/& }"
+          echo ${var/abc/$rep}
+          echo "${var/abc/$rep}"
+
+     will display four lines of "abc def", while
+
+          var=abcdef
+          rep='& '
+          echo ${var/abc/\& }
+          echo "${var/abc/\& }"
+          echo ${var/abc/"& "}
+          echo ${var/abc/"$rep"}
+
+     will display four lines of "& def".  Like the pattern removal
+     operators, double quotes surrounding the replacement string quote
+     the expanded characters, while double quotes enclosing the entire
+     parameter substitution do not, since the expansion is performed in
+     a context that doesn't take any enclosing double quotes into
+     account.
+
+     Since backslash can escape '&', it can also escape a backslash in
+     the replacement string.  This means that '\\' will insert a literal
+     backslash into the replacement, so these two 'echo' commands
+
+          var=abcdef
+          rep='\\&xyz'
+          echo ${var/abc/\\&xyz}
+          echo ${var/abc/$rep}
+
+     will both output '\abcxyzdef'.
+
+     It should rarely be necessary to enclose only STRING in double
+     quotes.
+
+     If the 'nocasematch' shell option (see the description of 'shopt'
+     in *note The Shopt Builtin::) is enabled, the match is performed
+     without regard to the case of alphabetic characters.  If PARAMETER
+     is '@' or '*', the substitution operation is applied to each
+     positional parameter in turn, and the expansion is the resultant
+     list.  If PARAMETER is an array variable subscripted with '@' or
+     '*', the substitution operation is applied to each member of the
+     array in turn, and the expansion is the resultant list.
+
+'${PARAMETER^PATTERN}'
+'${PARAMETER^^PATTERN}'
+'${PARAMETER,PATTERN}'
+'${PARAMETER,,PATTERN}'
+     This expansion modifies the case of alphabetic characters in
+     PARAMETER.  The PATTERN is expanded to produce a pattern just as in
+     filename expansion.  Each character in the expanded value of
+     PARAMETER is tested against PATTERN, and, if it matches the
+     pattern, its case is converted.  The pattern should not attempt to
+     match more than one character.
+
+     The '^' operator converts lowercase letters matching PATTERN to
+     uppercase; the ',' operator converts matching uppercase letters to
+     lowercase.  The '^^' and ',,' expansions convert each matched
+     character in the expanded value; the '^' and ',' expansions match
+     and convert only the first character in the expanded value.  If
+     PATTERN is omitted, it is treated like a '?', which matches every
+     character.
+
+     If PARAMETER is '@' or '*', the case modification operation is
+     applied to each positional parameter in turn, and the expansion is
+     the resultant list.  If PARAMETER is an array variable subscripted
+     with '@' or '*', the case modification operation is applied to each
+     member of the array in turn, and the expansion is the resultant
+     list.
+
+'${PARAMETER@OPERATOR}'
+     The expansion is either a transformation of the value of PARAMETER
+     or information about PARAMETER itself, depending on the value of
+     OPERATOR.  Each OPERATOR is a single letter:
+
+     'U'
+          The expansion is a string that is the value of PARAMETER with
+          lowercase alphabetic characters converted to uppercase.
+     'u'
+          The expansion is a string that is the value of PARAMETER with
+          the first character converted to uppercase, if it is
+          alphabetic.
+     'L'
+          The expansion is a string that is the value of PARAMETER with
+          uppercase alphabetic characters converted to lowercase.
+     'Q'
+          The expansion is a string that is the value of PARAMETER
+          quoted in a format that can be reused as input.
+     'E'
+          The expansion is a string that is the value of PARAMETER with
+          backslash escape sequences expanded as with the '$'...''
+          quoting mechanism.
+     'P'
+          The expansion is a string that is the result of expanding the
+          value of PARAMETER as if it were a prompt string (*note
+          Controlling the Prompt::).
+     'A'
+          The expansion is a string in the form of an assignment
+          statement or 'declare' command that, if evaluated, will
+          recreate PARAMETER with its attributes and value.
+     'K'
+          Produces a possibly-quoted version of the value of PARAMETER,
+          except that it prints the values of indexed and associative
+          arrays as a sequence of quoted key-value pairs (*note
+          Arrays::).
+     'a'
+          The expansion is a string consisting of flag values
+          representing PARAMETER's attributes.
+     'k'
+          Like the 'K' transformation, but expands the keys and values
+          of indexed and associative arrays to separate words after word
+          splitting.
+
+     If PARAMETER is '@' or '*', the operation is applied to each
+     positional parameter in turn, and the expansion is the resultant
+     list.  If PARAMETER is an array variable subscripted with '@' or
+     '*', the operation is applied to each member of the array in turn,
+     and the expansion is the resultant list.
+
+     The result of the expansion is subject to word splitting and
+     filename expansion as described below.

+
+3.5.4 Command Substitution
+--------------------------
+
+Command substitution allows the output of a command to replace the
+command itself.  Command substitution occurs when a command is enclosed
+as follows:
+     $(COMMAND)
+or
+     `COMMAND`
+
+Bash performs the expansion by executing COMMAND in a subshell
+environment and replacing the command substitution with the standard
+output of the command, with any trailing newlines deleted.  Embedded
+newlines are not deleted, but they may be removed during word splitting.
+The command substitution '$(cat FILE)' can be replaced by the equivalent
+but faster '$(< FILE)'.
+
+   When the old-style backquote form of substitution is used, backslash
+retains its literal meaning except when followed by '$', '`', or '\'.
+The first backquote not preceded by a backslash terminates the command
+substitution.  When using the '$(COMMAND)' form, all characters between
+the parentheses make up the command; none are treated specially.
+
+   Command substitutions may be nested.  To nest when using the
+backquoted form, escape the inner backquotes with backslashes.
+
+   If the substitution appears within double quotes, word splitting and
+filename expansion are not performed on the results.
+
+
+File: bashref.info,  Node: Arithmetic Expansion,  Next: Process Substitution,  Prev: Command Substitution,  Up: Shell Expansions
+
+3.5.5 Arithmetic Expansion
+--------------------------
+
+Arithmetic expansion allows the evaluation of an arithmetic expression
+and the substitution of the result.  The format for arithmetic expansion
+is:
+
+     $(( EXPRESSION ))
+
+   The EXPRESSION undergoes the same expansions as if it were within
+double quotes, but double quote characters in EXPRESSION are not treated
+specially and are removed.  All tokens in the expression undergo
+parameter and variable expansion, command substitution, and quote
+removal.  The result is treated as the arithmetic expression to be
+evaluated.  Arithmetic expansions may be nested.
+
+   The evaluation is performed according to the rules listed below
+(*note Shell Arithmetic::).  If the expression is invalid, Bash prints a
+message indicating failure to the standard error and no substitution
+occurs.
+
+
+File: bashref.info,  Node: Process Substitution,  Next: Word Splitting,  Prev: Arithmetic Expansion,  Up: Shell Expansions
+
+3.5.6 Process Substitution
+--------------------------
+
+Process substitution allows a process's input or output to be referred
+to using a filename.  It takes the form of
+     <(LIST)
+or
+     >(LIST)
+The process LIST is run asynchronously, and its input or output appears
+as a filename.  This filename is passed as an argument to the current
+command as the result of the expansion.  If the '>(LIST)' form is used,
+writing to the file will provide input for LIST.  If the '<(LIST)' form
+is used, the file passed as an argument should be read to obtain the
+output of LIST.  Note that no space may appear between the '<' or '>'
+and the left parenthesis, otherwise the construct would be interpreted
+as a redirection.  Process substitution is supported on systems that
+support named pipes (FIFOs) or the '/dev/fd' method of naming open
+files.
+
+   When available, process substitution is performed simultaneously with
+parameter and variable expansion, command substitution, and arithmetic
+expansion.
+
+
+File: bashref.info,  Node: Word Splitting,  Next: Filename Expansion,  Prev: Process Substitution,  Up: Shell Expansions
+
+3.5.7 Word Splitting
+--------------------
+
+The shell scans the results of parameter expansion, command
+substitution, and arithmetic expansion that did not occur within double
+quotes for word splitting.
+
+   The shell treats each character of '$IFS' as a delimiter, and splits
+the results of the other expansions into words using these characters as
+field terminators.  If 'IFS' is unset, or its value is exactly
+'<space><tab><newline>', the default, then sequences of ' <space>',
+'<tab>', and '<newline>' at the beginning and end of the results of the
+previous expansions are ignored, and any sequence of 'IFS' characters
+not at the beginning or end serves to delimit words.  If 'IFS' has a
+value other than the default, then sequences of the whitespace
+characters 'space', 'tab', and 'newline' are ignored at the beginning
+and end of the word, as long as the whitespace character is in the value
+of 'IFS' (an 'IFS' whitespace character).  Any character in 'IFS' that
+is not 'IFS' whitespace, along with any adjacent 'IFS' whitespace
+characters, delimits a field.  A sequence of 'IFS' whitespace characters
+is also treated as a delimiter.  If the value of 'IFS' is null, no word
+splitting occurs.
+
+   Explicit null arguments ('""' or '''') are retained and passed to
+commands as empty strings.  Unquoted implicit null arguments, resulting
+from the expansion of parameters that have no values, are removed.  If a
+parameter with no value is expanded within double quotes, a null
+argument results and is retained and passed to a command as an empty
+string.  When a quoted null argument appears as part of a word whose
+expansion is non-null, the null argument is removed.  That is, the word
+'-d''' becomes '-d' after word splitting and null argument removal.
+
+   Note that if no expansion occurs, no splitting is performed.

+
+3.5.8 Filename Expansion
+------------------------
+
+* Menu:
+
+* Pattern Matching::	How the shell matches patterns.
+
+After word splitting, unless the '-f' option has been set (*note The Set
+Builtin::), Bash scans each word for the characters '*', '?', and '['.
+If one of these characters appears, and is not quoted, then the word is
+regarded as a PATTERN, and replaced with an alphabetically sorted list
+of filenames matching the pattern (*note Pattern Matching::).  If no
+matching filenames are found, and the shell option 'nullglob' is
+disabled, the word is left unchanged.  If the 'nullglob' option is set,
+and no matches are found, the word is removed.  If the 'failglob' shell
+option is set, and no matches are found, an error message is printed and
+the command is not executed.  If the shell option 'nocaseglob' is
+enabled, the match is performed without regard to the case of alphabetic
+characters.
+
+   When a pattern is used for filename expansion, the character '.' at
+the start of a filename or immediately following a slash must be matched
+explicitly, unless the shell option 'dotglob' is set.  In order to match
+the filenames '.' and '..', the pattern must begin with '.' (for
+example, '.?'), even if 'dotglob' is set.  If the 'globskipdots' shell
+option is enabled, the filenames '.' and '..' are never matched, even if
+the pattern begins with a '.'.  When not matching filenames, the '.'
+character is not treated specially.
+
+   When matching a filename, the slash character must always be matched
+explicitly by a slash in the pattern, but in other matching contexts it
+can be matched by a special pattern character as described below (*note
+Pattern Matching::).
+
+   See the description of 'shopt' in *note The Shopt Builtin::, for a
+description of the 'nocaseglob', 'nullglob', 'globskipdots', 'failglob',
+and 'dotglob' options.
+
+   The 'GLOBIGNORE' shell variable may be used to restrict the set of
+file names matching a pattern.  If 'GLOBIGNORE' is set, each matching
+file name that also matches one of the patterns in 'GLOBIGNORE' is
+removed from the list of matches.  If the 'nocaseglob' option is set,
+the matching against the patterns in 'GLOBIGNORE' is performed without
+regard to case.  The filenames '.' and '..' are always ignored when
+'GLOBIGNORE' is set and not null.  However, setting 'GLOBIGNORE' to a
+non-null value has the effect of enabling the 'dotglob' shell option, so
+all other filenames beginning with a '.' will match.  To get the old
+behavior of ignoring filenames beginning with a '.', make '.*' one of
+the patterns in 'GLOBIGNORE'.  The 'dotglob' option is disabled when
+'GLOBIGNORE' is unset.
+
+
+File: bashref.info,  Node: Pattern Matching,  Up: Filename Expansion
+
+3.5.8.1 Pattern Matching
+........................
+
+Any character that appears in a pattern, other than the special pattern
+characters described below, matches itself.  The NUL character may not
+occur in a pattern.  A backslash escapes the following character; the
+escaping backslash is discarded when matching.  The special pattern
+characters must be quoted if they are to be matched literally.
+
+   The special pattern characters have the following meanings:
+'*'
+     Matches any string, including the null string.  When the 'globstar'
+     shell option is enabled, and '*' is used in a filename expansion
+     context, two adjacent '*'s used as a single pattern will match all
+     files and zero or more directories and subdirectories.  If followed
+     by a '/', two adjacent '*'s will match only directories and
+     subdirectories.
+'?'
+     Matches any single character.
+'[...]'
+     Matches any one of the enclosed characters.  A pair of characters
+     separated by a hyphen denotes a RANGE EXPRESSION; any character
+     that falls between those two characters, inclusive, using the
+     current locale's collating sequence and character set, is matched.
+     If the first character following the '[' is a '!' or a '^' then any
+     character not enclosed is matched.  A '-' may be matched by
+     including it as the first or last character in the set.  A ']' may
+     be matched by including it as the first character in the set.  The
+     sorting order of characters in range expressions, and the
+     characters included in the range, are determined by the current
+     locale and the values of the 'LC_COLLATE' and 'LC_ALL' shell
+     variables, if set.
+
+     For example, in the default C locale, '[a-dx-z]' is equivalent to
+     '[abcdxyz]'.  Many locales sort characters in dictionary order, and
+     in these locales '[a-dx-z]' is typically not equivalent to
+     '[abcdxyz]'; it might be equivalent to '[aBbCcDdxYyZz]', for
+     example.  To obtain the traditional interpretation of ranges in
+     bracket expressions, you can force the use of the C locale by
+     setting the 'LC_COLLATE' or 'LC_ALL' environment variable to the
+     value 'C', or enable the 'globasciiranges' shell option.
+
+     Within '[' and ']', "character classes" can be specified using the
+     syntax '[:'CLASS':]', where CLASS is one of the following classes
+     defined in the POSIX standard:
+          alnum   alpha   ascii   blank   cntrl   digit   graph   lower
+          print   punct   space   upper   word    xdigit
+     A character class matches any character belonging to that class.
+     The 'word' character class matches letters, digits, and the
+     character '_'.
+
+     Within '[' and ']', an "equivalence class" can be specified using
+     the syntax '[='C'=]', which matches all characters with the same
+     collation weight (as defined by the current locale) as the
+     character C.
+
+     Within '[' and ']', the syntax '[.'SYMBOL'.]' matches the collating
+     symbol SYMBOL.
+
+   If the 'extglob' shell option is enabled using the 'shopt' builtin,
+the shell recognizes several extended pattern matching operators.  In
+the following description, a PATTERN-LIST is a list of one or more
+patterns separated by a '|'.  When matching filenames, the 'dotglob'
+shell option determines the set of filenames that are tested, as
+described above.  Composite patterns may be formed using one or more of
+the following sub-patterns:
+
+'?(PATTERN-LIST)'
+     Matches zero or one occurrence of the given patterns.
+
+'*(PATTERN-LIST)'
+     Matches zero or more occurrences of the given patterns.
+
+'+(PATTERN-LIST)'
+     Matches one or more occurrences of the given patterns.
+
+'@(PATTERN-LIST)'
+     Matches one of the given patterns.
+
+'!(PATTERN-LIST)'
+     Matches anything except one of the given patterns.
+
+   The 'extglob' option changes the behavior of the parser, since the
+parentheses are normally treated as operators with syntactic meaning.
+To ensure that extended matching patterns are parsed correctly, make
+sure that 'extglob' is enabled before parsing constructs containing the
+patterns, including shell functions and command substitutions.
+
+   When matching filenames, the 'dotglob' shell option determines the
+set of filenames that are tested: when 'dotglob' is enabled, the set of
+filenames includes all files beginning with '.', but the filenames '.'
+and '..' must be matched by a pattern or sub-pattern that begins with a
+dot; when it is disabled, the set does not include any filenames
+beginning with "."  unless the pattern or sub-pattern begins with a '.'.
+As above, '.' only has a special meaning when matching filenames.
+
+   Complicated extended pattern matching against long strings is slow,
+especially when the patterns contain alternations and the strings
+contain multiple matches.  Using separate matches against shorter
+strings, or using arrays of strings instead of a single long string, may
+be faster.

+-------------------
+
+After the preceding expansions, all unquoted occurrences of the
+characters '\', ''', and '"' that did not result from one of the above

+
+
+File: bashref.info,  Node: Redirections,  Next: Executing Commands,  Prev: Shell Expansions,  Up: Basic Shell Features
+
+3.6 Redirections
+================
+
+Before a command is executed, its input and output may be "redirected"
+using a special notation interpreted by the shell.  "Redirection" allows
+commands' file handles to be duplicated, opened, closed, made to refer
+to different files, and can change the files the command reads from and
+writes to.  Redirection may also be used to modify file handles in the
+current shell execution environment.  The following redirection
+operators may precede or appear anywhere within a simple command or may
+follow a command.  Redirections are processed in the order they appear,
+from left to right.
+
+   Each redirection that may be preceded by a file descriptor number may
+instead be preceded by a word of the form {VARNAME}.  In this case, for
+each redirection operator except >&- and <&-, the shell will allocate a
+file descriptor greater than 10 and assign it to {VARNAME}.  If >&- or
+<&- is preceded by {VARNAME}, the value of VARNAME defines the file
+descriptor to close.  If {VARNAME} is supplied, the redirection persists
+beyond the scope of the command, allowing the shell programmer to manage
+the file descriptor's lifetime manually.  The 'varredir_close' shell
+option manages this behavior (*note The Shopt Builtin::).
+
+   In the following descriptions, if the file descriptor number is
+omitted, and the first character of the redirection operator is '<', the
+redirection refers to the standard input (file descriptor 0).  If the
+first character of the redirection operator is '>', the redirection
+refers to the standard output (file descriptor 1).
+
+   The word following the redirection operator in the following
+descriptions, unless otherwise noted, is subjected to brace expansion,
+tilde expansion, parameter expansion, command substitution, arithmetic
+expansion, quote removal, filename expansion, and word splitting.  If it
+expands to more than one word, Bash reports an error.
+
+   Note that the order of redirections is significant.  For example, the
+command
+     ls > DIRLIST 2>&1
+directs both standard output (file descriptor 1) and standard error
+(file descriptor 2) to the file DIRLIST, while the command
+     ls 2>&1 > DIRLIST
+directs only the standard output to file DIRLIST, because the standard
+error was made a copy of the standard output before the standard output
+was redirected to DIRLIST.
+
+   Bash handles several filenames specially when they are used in
+redirections, as described in the following table.  If the operating
+system on which Bash is running provides these special files, bash will
+use them; otherwise it will emulate them internally with the behavior
+described below.
+
+'/dev/fd/FD'
+     If FD is a valid integer, file descriptor FD is duplicated.
+
+'/dev/stdin'
+     File descriptor 0 is duplicated.
+
+'/dev/stdout'
+     File descriptor 1 is duplicated.
+
+'/dev/stderr'
+     File descriptor 2 is duplicated.
+
+'/dev/tcp/HOST/PORT'
+     If HOST is a valid hostname or Internet address, and PORT is an
+     integer port number or service name, Bash attempts to open the
+     corresponding TCP socket.
+
+'/dev/udp/HOST/PORT'
+     If HOST is a valid hostname or Internet address, and PORT is an
+     integer port number or service name, Bash attempts to open the
+     corresponding UDP socket.
+
+   A failure to open or create a file causes the redirection to fail.
+
+   Redirections using file descriptors greater than 9 should be used
+with care, as they may conflict with file descriptors the shell uses
+internally.
+
+3.6.1 Redirecting Input
+-----------------------
+
+Redirection of input causes the file whose name results from the
+expansion of WORD to be opened for reading on file descriptor 'n', or
+the standard input (file descriptor 0) if 'n' is not specified.
+
+   The general format for redirecting input is:
+     [N]<WORD
+
+3.6.2 Redirecting Output
+------------------------
+
+Redirection of output causes the file whose name results from the
+expansion of WORD to be opened for writing on file descriptor N, or the
+standard output (file descriptor 1) if N is not specified.  If the file
+does not exist it is created; if it does exist it is truncated to zero
+size.
+
+   The general format for redirecting output is:
+     [N]>[|]WORD
+
+   If the redirection operator is '>', and the 'noclobber' option to the
+'set' builtin has been enabled, the redirection will fail if the file
+whose name results from the expansion of WORD exists and is a regular
+file.  If the redirection operator is '>|', or the redirection operator
+is '>' and the 'noclobber' option is not enabled, the redirection is
+attempted even if the file named by WORD exists.
+
+3.6.3 Appending Redirected Output
+---------------------------------
+
+Redirection of output in this fashion causes the file whose name results
+from the expansion of WORD to be opened for appending on file descriptor
+N, or the standard output (file descriptor 1) if N is not specified.  If
+the file does not exist it is created.
+
+   The general format for appending output is:
+     [N]>>WORD
+
+3.6.4 Redirecting Standard Output and Standard Error
+----------------------------------------------------
+
+This construct allows both the standard output (file descriptor 1) and
+the standard error output (file descriptor 2) to be redirected to the
+file whose name is the expansion of WORD.
+
+   There are two formats for redirecting standard output and standard
+error:
+     &>WORD
+and
+     >&WORD
+Of the two forms, the first is preferred.  This is semantically
+equivalent to
+     >WORD 2>&1
+   When using the second form, WORD may not expand to a number or '-'.
+If it does, other redirection operators apply (see Duplicating File
+Descriptors below) for compatibility reasons.
+
+3.6.5 Appending Standard Output and Standard Error
+--------------------------------------------------
+
+This construct allows both the standard output (file descriptor 1) and
+the standard error output (file descriptor 2) to be appended to the file
+whose name is the expansion of WORD.
+
+   The format for appending standard output and standard error is:
+     &>>WORD
+This is semantically equivalent to
+     >>WORD 2>&1
+   (see Duplicating File Descriptors below).
+
+3.6.6 Here Documents
+--------------------
+
+This type of redirection instructs the shell to read input from the
+current source until a line containing only WORD (with no trailing
+blanks) is seen.  All of the lines read up to that point are then used
+as the standard input (or file descriptor N if N is specified) for a
+command.
+
+   The format of here-documents is:
+     [N]<<[-]WORD
+             HERE-DOCUMENT
+     DELIMITER
+
+   No parameter and variable expansion, command substitution, arithmetic
+expansion, or filename expansion is performed on WORD.  If any part of
+WORD is quoted, the DELIMITER is the result of quote removal on WORD,
+and the lines in the here-document are not expanded.  If WORD is
+unquoted, all lines of the here-document are subjected to parameter
+expansion, command substitution, and arithmetic expansion, the character
+sequence '\newline' is ignored, and '\' must be used to quote the
+characters '\', '$', and '`'.
+
+   If the redirection operator is '<<-', then all leading tab characters
+are stripped from input lines and the line containing DELIMITER.  This
+allows here-documents within shell scripts to be indented in a natural
+fashion.
+
+3.6.7 Here Strings
+------------------
+
+A variant of here documents, the format is:
+     [N]<<< WORD
+
+   The WORD undergoes tilde expansion, parameter and variable expansion,
+command substitution, arithmetic expansion, and quote removal.  Filename
+expansion and word splitting are not performed.  The result is supplied
+as a single string, with a newline appended, to the command on its
+standard input (or file descriptor N if N is specified).
+
+3.6.8 Duplicating File Descriptors
+----------------------------------
+
+The redirection operator
+     [N]<&WORD
+is used to duplicate input file descriptors.  If WORD expands to one or
+more digits, the file descriptor denoted by N is made to be a copy of
+that file descriptor.  If the digits in WORD do not specify a file
+descriptor open for input, a redirection error occurs.  If WORD
+evaluates to '-', file descriptor N is closed.  If N is not specified,
+the standard input (file descriptor 0) is used.
+
+   The operator
+     [N]>&WORD
+is used similarly to duplicate output file descriptors.  If N is not
+specified, the standard output (file descriptor 1) is used.  If the
+digits in WORD do not specify a file descriptor open for output, a
+redirection error occurs.  If WORD evaluates to '-', file descriptor N
+is closed.  As a special case, if N is omitted, and WORD does not expand
+to one or more digits or '-', the standard output and standard error are
+redirected as described previously.
+
+3.6.9 Moving File Descriptors
+-----------------------------
+
+The redirection operator
+     [N]<&DIGIT-
+moves the file descriptor DIGIT to file descriptor N, or the standard
+input (file descriptor 0) if N is not specified.  DIGIT is closed after
+being duplicated to N.
+
+   Similarly, the redirection operator
+     [N]>&DIGIT-
+moves the file descriptor DIGIT to file descriptor N, or the standard
+output (file descriptor 1) if N is not specified.
+
+3.6.10 Opening File Descriptors for Reading and Writing
+-------------------------------------------------------
+
+The redirection operator
+     [N]<>WORD
+causes the file whose name is the expansion of WORD to be opened for
+both reading and writing on file descriptor N, or on file descriptor 0
+if N is not specified.  If the file does not exist, it is created.

+
+3.7.1 Simple Command Expansion
+------------------------------
+
+When a simple command is executed, the shell performs the following
+expansions, assignments, and redirections, from left to right, in the
+following order.
+
+  1. The words that the parser has marked as variable assignments (those
+     preceding the command name) and redirections are saved for later
+     processing.
+
+  2. The words that are not variable assignments or redirections are
+     expanded (*note Shell Expansions::).  If any words remain after
+     expansion, the first word is taken to be the name of the command
+     and the remaining words are the arguments.
+
+  3. Redirections are performed as described above (*note
+     Redirections::).
+
+  4. The text after the '=' in each variable assignment undergoes tilde
+     expansion, parameter expansion, command substitution, arithmetic
+     expansion, and quote removal before being assigned to the variable.
+
+   If no command name results, the variable assignments affect the
+current shell environment.  In the case of such a command (one that
+consists only of assignment statements and redirections), assignment
+statements are performed before redirections.  Otherwise, the variables
+are added to the environment of the executed command and do not affect
+the current shell environment.  If any of the assignments attempts to
+assign a value to a readonly variable, an error occurs, and the command
+exits with a non-zero status.
+
+   If no command name results, redirections are performed, but do not
+affect the current shell environment.  A redirection error causes the
+command to exit with a non-zero status.
+
+   If there is a command name left after expansion, execution proceeds
+as described below.  Otherwise, the command exits.  If one of the
+expansions contained a command substitution, the exit status of the
+command is the exit status of the last command substitution performed.
+If there were no command substitutions, the command exits with a status
+of zero.

+command and an optional list of arguments, the following actions are
+taken.
+
+  1. If the command name contains no slashes, the shell attempts to
+     locate it.  If there exists a shell function by that name, that
+     function is invoked as described in *note Shell Functions::.
+
+  2. If the name does not match a function, the shell searches for it in
+     the list of shell builtins.  If a match is found, that builtin is
+     invoked.
+
+  3. If the name is neither a shell function nor a builtin, and contains
+     no slashes, Bash searches each element of '$PATH' for a directory
+     containing an executable file by that name.  Bash uses a hash table
+     to remember the full pathnames of executable files to avoid
+     multiple 'PATH' searches (see the description of 'hash' in *note
+     Bourne Shell Builtins::).  A full search of the directories in
+     '$PATH' is performed only if the command is not found in the hash
+     table.  If the search is unsuccessful, the shell searches for a
+     defined shell function named 'command_not_found_handle'.  If that
+     function exists, it is invoked in a separate execution environment
+     with the original command and the original command's arguments as
+     its arguments, and the function's exit status becomes the exit
+     status of that subshell.  If that function is not defined, the
+     shell prints an error message and returns an exit status of 127.
+
+  4. If the search is successful, or if the command name contains one or
+     more slashes, the shell executes the named program in a separate
+     execution environment.  Argument 0 is set to the name given, and
+     the remaining arguments to the command are set to the arguments
+     supplied, if any.
+
+  5. If this execution fails because the file is not in executable
+     format, and the file is not a directory, it is assumed to be a
+     "shell script" and the shell executes it as described in *note
+     Shell Scripts::.
+
+  6. If the command was not begun asynchronously, the shell waits for
+     the command to complete and collects its exit status.

+
+3.7.3 Command Execution Environment
+-----------------------------------
+
+The shell has an "execution environment", which consists of the
+following:
+
+   * open files inherited by the shell at invocation, as modified by
+     redirections supplied to the 'exec' builtin
+
+   * the current working directory as set by 'cd', 'pushd', or 'popd',
+     or inherited by the shell at invocation
+
+   * the file creation mode mask as set by 'umask' or inherited from the
+     shell's parent
+
+   * current traps set by 'trap'
+
+   * shell parameters that are set by variable assignment or with 'set'
+     or inherited from the shell's parent in the environment
+
+   * shell functions defined during execution or inherited from the
+     shell's parent in the environment
+
+   * options enabled at invocation (either by default or with
+     command-line arguments) or by 'set'
+
+   * options enabled by 'shopt' (*note The Shopt Builtin::)
+
+   * shell aliases defined with 'alias' (*note Aliases::)
+
+   * various process IDs, including those of background jobs (*note
+     Lists::), the value of '$$', and the value of '$PPID'
+
+   When a simple command other than a builtin or shell function is to be
+executed, it is invoked in a separate execution environment that
+consists of the following.  Unless otherwise noted, the values are
+inherited from the shell.
+
+   * the shell's open files, plus any modifications and additions
+     specified by redirections to the command
+
+   * the current working directory
+
+   * the file creation mode mask
+
+   * shell variables and functions marked for export, along with
+     variables exported for the command, passed in the environment
+     (*note Environment::)
+
+   * traps caught by the shell are reset to the values inherited from
+     the shell's parent, and traps ignored by the shell are ignored
+
+   A command invoked in this separate environment cannot affect the
+shell's execution environment.
+
+   A "subshell" is a copy of the shell process.
+
+   Command substitution, commands grouped with parentheses, and
+asynchronous commands are invoked in a subshell environment that is a
+duplicate of the shell environment, except that traps caught by the
+shell are reset to the values that the shell inherited from its parent
+at invocation.  Builtin commands that are invoked as part of a pipeline
+are also executed in a subshell environment.  Changes made to the
+subshell environment cannot affect the shell's execution environment.
+
+   Subshells spawned to execute command substitutions inherit the value
+of the '-e' option from the parent shell.  When not in POSIX mode, Bash
+clears the '-e' option in such subshells.
+
+   If a command is followed by a '&' and job control is not active, the
+default standard input for the command is the empty file '/dev/null'.
+Otherwise, the invoked command inherits the file descriptors of the
+calling shell as modified by redirections.
+
+
+File: bashref.info,  Node: Environment,  Next: Exit Status,  Prev: Command Execution Environment,  Up: Executing Commands
+
+3.7.4 Environment
+-----------------
+
+When a program is invoked it is given an array of strings called the
+"environment".  This is a list of name-value pairs, of the form
+'name=value'.
+
+   Bash provides several ways to manipulate the environment.  On
+invocation, the shell scans its own environment and creates a parameter
+for each name found, automatically marking it for 'export' to child
+processes.  Executed commands inherit the environment.  The 'export' and
+'declare -x' commands allow parameters and functions to be added to and
+deleted from the environment.  If the value of a parameter in the
+environment is modified, the new value becomes part of the environment,
+replacing the old.  The environment inherited by any executed command
+consists of the shell's initial environment, whose values may be
+modified in the shell, less any pairs removed by the 'unset' and 'export
+-n' commands, plus any additions via the 'export' and 'declare -x'
+commands.
+
+   The environment for any simple command or function may be augmented
+temporarily by prefixing it with parameter assignments, as described in
+*note Shell Parameters::.  These assignment statements affect only the
+environment seen by that command.
+
+   If the '-k' option is set (*note The Set Builtin::), then all
+parameter assignments are placed in the environment for a command, not
+just those that precede the command name.
+
+   When Bash invokes an external command, the variable '$_' is set to
+the full pathname of the command and passed to that command in its
+environment.
+
+
+File: bashref.info,  Node: Exit Status,  Next: Signals,  Prev: Environment,  Up: Executing Commands
+
+3.7.5 Exit Status
+-----------------
+
+The exit status of an executed command is the value returned by the
+'waitpid' system call or equivalent function.  Exit statuses fall
+between 0 and 255, though, as explained below, the shell may use values
+above 125 specially.  Exit statuses from shell builtins and compound
+commands are also limited to this range.  Under certain circumstances,
+the shell will use special values to indicate specific failure modes.
+
+   For the shell's purposes, a command which exits with a zero exit
+status has succeeded.  A non-zero exit status indicates failure.  This
+seemingly counter-intuitive scheme is used so there is one well-defined
+way to indicate success and a variety of ways to indicate various
+failure modes.  When a command terminates on a fatal signal whose number
+is N, Bash uses the value 128+N as the exit status.
+
+   If a command is not found, the child process created to execute it
+returns a status of 127.  If a command is found but is not executable,
+the return status is 126.
+
+   If a command fails because of an error during expansion or
+redirection, the exit status is greater than zero.
+
+   The exit status is used by the Bash conditional commands (*note
+Conditional Constructs::) and some of the list constructs (*note
+Lists::).
+
+   All of the Bash builtins return an exit status of zero if they
+succeed and a non-zero status on failure, so they may be used by the
+conditional and list constructs.  All builtins return an exit status of
+2 to indicate incorrect usage, generally invalid options or missing
+arguments.
+
+   The exit status of the last command is available in the special
+parameter $?  (*note Special Parameters::).
+
+
+File: bashref.info,  Node: Signals,  Prev: Exit Status,  Up: Executing Commands
+
+3.7.6 Signals
+-------------
+
+When Bash is interactive, in the absence of any traps, it ignores
+'SIGTERM' (so that 'kill 0' does not kill an interactive shell), and
+'SIGINT' is caught and handled (so that the 'wait' builtin is
+interruptible).  When Bash receives a 'SIGINT', it breaks out of any
+executing loops.  In all cases, Bash ignores 'SIGQUIT'.  If job control
+is in effect (*note Job Control::), Bash ignores 'SIGTTIN', 'SIGTTOU',
+and 'SIGTSTP'.
+
+   Non-builtin commands started by Bash have signal handlers set to the
+values inherited by the shell from its parent.  When job control is not
+in effect, asynchronous commands ignore 'SIGINT' and 'SIGQUIT' in
+addition to these inherited handlers.  Commands run as a result of
+command substitution ignore the keyboard-generated job control signals
+'SIGTTIN', 'SIGTTOU', and 'SIGTSTP'.
+
+   The shell exits by default upon receipt of a 'SIGHUP'.  Before
+exiting, an interactive shell resends the 'SIGHUP' to all jobs, running
+or stopped.  Stopped jobs are sent 'SIGCONT' to ensure that they receive
+the 'SIGHUP'.  To prevent the shell from sending the 'SIGHUP' signal to
+a particular job, it should be removed from the jobs table with the
+'disown' builtin (*note Job Control Builtins::) or marked to not receive
+'SIGHUP' using 'disown -h'.
+
+   If the 'huponexit' shell option has been set with 'shopt' (*note The
+Shopt Builtin::), Bash sends a 'SIGHUP' to all jobs when an interactive
+login shell exits.
+
+   If Bash is waiting for a command to complete and receives a signal
+for which a trap has been set, the trap will not be executed until the
+command completes.  When Bash is waiting for an asynchronous command via
+the 'wait' builtin, the reception of a signal for which a trap has been
+set will cause the 'wait' builtin to return immediately with an exit
+status greater than 128, immediately after which the trap is executed.
+
+   When job control is not enabled, and Bash is waiting for a foreground
+command to complete, the shell receives keyboard-generated signals such
+as 'SIGINT' (usually generated by '^C') that users commonly intend to
+send to that command.  This happens because the shell and the command
+are in the same process group as the terminal, and '^C' sends 'SIGINT'
+to all processes in that process group.  See *note Job Control::, for a
+more in-depth discussion of process groups.
+
+   When Bash is running without job control enabled and receives
+'SIGINT' while waiting for a foreground command, it waits until that
+foreground command terminates and then decides what to do about the
+'SIGINT':
+
+  1. If the command terminates due to the 'SIGINT', Bash concludes that
+     the user meant to end the entire script, and acts on the 'SIGINT'
+     (e.g., by running a 'SIGINT' trap or exiting itself);
+
+  2. If the pipeline does not terminate due to 'SIGINT', the program
+     handled the 'SIGINT' itself and did not treat it as a fatal signal.
+     In that case, Bash does not treat 'SIGINT' as a fatal signal,
+     either, instead assuming that the 'SIGINT' was used as part of the
+     program's normal operation (e.g., 'emacs' uses it to abort editing
+     commands) or deliberately discarded.  However, Bash will run any
+     trap set on 'SIGINT', as it does with any other trapped signal it
+     receives while it is waiting for the foreground command to
+     complete, for compatibility.

+
+3.8 Shell Scripts
+=================
+
+A shell script is a text file containing shell commands.  When such a
+file is used as the first non-option argument when invoking Bash, and
+neither the '-c' nor '-s' option is supplied (*note Invoking Bash::),
+Bash reads and executes commands from the file, then exits.  This mode
+of operation creates a non-interactive shell.  The shell first searches
+for the file in the current directory, and looks in the directories in
+'$PATH' if not found there.
+
+   When Bash runs a shell script, it sets the special parameter '0' to
+the name of the file, rather than the name of the shell, and the
+positional parameters are set to the remaining arguments, if any are
+given.  If no additional arguments are supplied, the positional
+parameters are unset.
+
+   A shell script may be made executable by using the 'chmod' command to
+turn on the execute bit.  When Bash finds such a file while searching
+the '$PATH' for a command, it creates a new instance of itself to
+execute it.  In other words, executing
+     filename ARGUMENTS
+is equivalent to executing
+     bash filename ARGUMENTS
+
+if 'filename' is an executable shell script.  This subshell
+reinitializes itself, so that the effect is as if a new shell had been
+invoked to interpret the script, with the exception that the locations
+of commands remembered by the parent (see the description of 'hash' in
+*note Bourne Shell Builtins::) are retained by the child.
+
+   Most versions of Unix make this a part of the operating system's
+command execution mechanism.  If the first line of a script begins with
+the two characters '#!', the remainder of the line specifies an
+interpreter for the program and, depending on the operating system, one
+or more optional arguments for that interpreter.  Thus, you can specify
+Bash, 'awk', Perl, or some other interpreter and write the rest of the
+script file in that language.
+
+   The arguments to the interpreter consist of one or more optional
+arguments following the interpreter name on the first line of the script
+file, followed by the name of the script file, followed by the rest of
+the arguments supplied to the script.  The details of how the
+interpreter line is split into an interpreter name and a set of
+arguments vary across systems.  Bash will perform this action on
+operating systems that do not handle it themselves.  Note that some
+older versions of Unix limit the interpreter name and a single argument
+to a maximum of 32 characters, so it's not portable to assume that using
+more than one argument will work.
+
+   Bash scripts often begin with '#! /bin/bash' (assuming that Bash has
+been installed in '/bin'), since this ensures that Bash will be used to
+interpret the script, even if it is executed under another shell.  It's
+a common idiom to use 'env' to find 'bash' even if it's been installed
+in another directory: '#!/usr/bin/env bash' will find the first
+occurrence of 'bash' in '$PATH'.

+4 Shell Builtin Commands

+* Bourne Shell Builtins::	Builtin commands inherited from the Bourne
+				Shell.
+* Bash Builtins::		Table of builtins specific to Bash.
+* Modifying Shell Behavior::	Builtins to modify shell attributes and
+				optional behavior.
+* Special Builtins::		Builtin commands classified specially by

+
+Builtin commands are contained within the shell itself.  When the name
+of a builtin command is used as the first word of a simple command
+(*note Simple Commands::), the shell executes the command directly,
+without invoking another program.  Builtin commands are necessary to
+implement functionality impossible or inconvenient to obtain with
+separate utilities.
+
+   This section briefly describes the builtins which Bash inherits from
+the Bourne Shell, as well as the builtin commands which are unique to or
+have been extended in Bash.
+
+   Several builtin commands are described in other chapters: builtin
+commands which provide the Bash interface to the job control facilities
+(*note Job Control Builtins::), the directory stack (*note Directory
+Stack Builtins::), the command history (*note Bash History Builtins::),
+and the programmable completion facilities (*note Programmable
+Completion Builtins::).
+
+   Many of the builtins have been extended by POSIX or Bash.
+
+   Unless otherwise noted, each builtin command documented as accepting
+options preceded by '-' accepts '--' to signify the end of the options.
+The ':', 'true', 'false', and 'test'/'[' builtins do not accept options
+and do not treat '--' specially.  The 'exit', 'logout', 'return',
+'break', 'continue', 'let', and 'shift' builtins accept and process
+arguments beginning with '-' without requiring '--'.  Other builtins
+that accept arguments but are not specified as accepting options
+interpret arguments beginning with '-' as invalid options and require
+'--' to prevent this interpretation.
+
+
+File: bashref.info,  Node: Bourne Shell Builtins,  Next: Bash Builtins,  Up: Shell Builtin Commands
+
+4.1 Bourne Shell Builtins
+=========================
+
+The following shell builtin commands are inherited from the Bourne
+Shell.  These commands are implemented as specified by the POSIX
+standard.
+
+': (a colon)'
+          : [ARGUMENTS]
+
+     Do nothing beyond expanding ARGUMENTS and performing redirections.
+     The return status is zero.
+
+'. (a period)'
+          . FILENAME [ARGUMENTS]
+
+     Read and execute commands from the FILENAME argument in the current
+     shell context.  If FILENAME does not contain a slash, the 'PATH'
+     variable is used to find FILENAME, but FILENAME does not need to be
+     executable.  When Bash is not in POSIX mode, it searches the
+     current directory if FILENAME is not found in '$PATH'.  If any
+     ARGUMENTS are supplied, they become the positional parameters when
+     FILENAME is executed.  Otherwise the positional parameters are
+     unchanged.  If the '-T' option is enabled, '.' inherits any trap on
+     'DEBUG'; if it is not, any 'DEBUG' trap string is saved and
+     restored around the call to '.', and '.' unsets the 'DEBUG' trap
+     while it executes.  If '-T' is not set, and the sourced file
+     changes the 'DEBUG' trap, the new value is retained when '.'
+     completes.  The return status is the exit status of the last
+     command executed, or zero if no commands are executed.  If FILENAME
+     is not found, or cannot be read, the return status is non-zero.
+     This builtin is equivalent to 'source'.
+
+'break'
+          break [N]
+
+     Exit from a 'for', 'while', 'until', or 'select' loop.  If N is
+     supplied, the Nth enclosing loop is exited.  N must be greater than
+     or equal to 1.  The return status is zero unless N is not greater
+     than or equal to 1.
+
+'cd'
+          cd [-L|[-P [-e]] [-@] [DIRECTORY]
+
+     Change the current working directory to DIRECTORY.  If DIRECTORY is
+     not supplied, the value of the 'HOME' shell variable is used.  If
+     the shell variable 'CDPATH' exists, it is used as a search path:
+     each directory name in 'CDPATH' is searched for DIRECTORY, with
+     alternative directory names in 'CDPATH' separated by a colon (':').
+     If DIRECTORY begins with a slash, 'CDPATH' is not used.
+
+     The '-P' option means to not follow symbolic links: symbolic links
+     are resolved while 'cd' is traversing DIRECTORY and before
+     processing an instance of '..' in DIRECTORY.
+
+     By default, or when the '-L' option is supplied, symbolic links in
+     DIRECTORY are resolved after 'cd' processes an instance of '..' in
+     DIRECTORY.
+
+     If '..' appears in DIRECTORY, it is processed by removing the
+     immediately preceding pathname component, back to a slash or the
+     beginning of DIRECTORY.
+
+     If the '-e' option is supplied with '-P' and the current working
+     directory cannot be successfully determined after a successful
+     directory change, 'cd' will return an unsuccessful status.
+
+     On systems that support it, the '-@' option presents the extended
+     attributes associated with a file as a directory.
+
+     If DIRECTORY is '-', it is converted to '$OLDPWD' before the
+     directory change is attempted.
+
+     If a non-empty directory name from 'CDPATH' is used, or if '-' is
+     the first argument, and the directory change is successful, the
+     absolute pathname of the new working directory is written to the
+     standard output.
+
+     If the directory change is successful, 'cd' sets the value of the
+     'PWD' environment variable to the new directory name, and sets the
+     'OLDPWD' environment variable to the value of the current working
+     directory before the change.
+
+     The return status is zero if the directory is successfully changed,
+     non-zero otherwise.
+
+'continue'
+          continue [N]
+
+     Resume the next iteration of an enclosing 'for', 'while', 'until',
+     or 'select' loop.  If N is supplied, the execution of the Nth
+     enclosing loop is resumed.  N must be greater than or equal to 1.
+     The return status is zero unless N is not greater than or equal to
+     1.
+
+'eval'
+          eval [ARGUMENTS]
+
+     The arguments are concatenated together into a single command,
+     which is then read and executed, and its exit status returned as
+     the exit status of 'eval'.  If there are no arguments or only empty
+     arguments, the return status is zero.
+
+'exec'
+          exec [-cl] [-a NAME] [COMMAND [ARGUMENTS]]
+
+     If COMMAND is supplied, it replaces the shell without creating a
+     new process.  If the '-l' option is supplied, the shell places a
+     dash at the beginning of the zeroth argument passed to COMMAND.
+     This is what the 'login' program does.  The '-c' option causes
+     COMMAND to be executed with an empty environment.  If '-a' is
+     supplied, the shell passes NAME as the zeroth argument to COMMAND.
+     If COMMAND cannot be executed for some reason, a non-interactive
+     shell exits, unless the 'execfail' shell option is enabled.  In
+     that case, it returns failure.  An interactive shell returns
+     failure if the file cannot be executed.  A subshell exits
+     unconditionally if 'exec' fails.  If no COMMAND is specified,
+     redirections may be used to affect the current shell environment.
+     If there are no redirection errors, the return status is zero;
+     otherwise the return status is non-zero.
+
+'exit'
+          exit [N]
+
+     Exit the shell, returning a status of N to the shell's parent.  If
+     N is omitted, the exit status is that of the last command executed.
+     Any trap on 'EXIT' is executed before the shell terminates.
+
+'export'
+          export [-fn] [-p] [NAME[=VALUE]]
+
+     Mark each NAME to be passed to child processes in the environment.
+     If the '-f' option is supplied, the NAMEs refer to shell functions;
+     otherwise the names refer to shell variables.  The '-n' option
+     means to no longer mark each NAME for export.  If no NAMEs are
+     supplied, or if the '-p' option is given, a list of names of all
+     exported variables is displayed.  The '-p' option displays output
+     in a form that may be reused as input.  If a variable name is
+     followed by =VALUE, the value of the variable is set to VALUE.
+
+     The return status is zero unless an invalid option is supplied, one
+     of the names is not a valid shell variable name, or '-f' is
+     supplied with a name that is not a shell function.
+
+'getopts'
+          getopts OPTSTRING NAME [ARG ...]
+
+     'getopts' is used by shell scripts to parse positional parameters.
+     OPTSTRING contains the option characters to be recognized; if a
+     character is followed by a colon, the option is expected to have an
+     argument, which should be separated from it by whitespace.  The
+     colon (':') and question mark ('?') may not be used as option
+     characters.  Each time it is invoked, 'getopts' places the next
+     option in the shell variable NAME, initializing NAME if it does not
+     exist, and the index of the next argument to be processed into the
+     variable 'OPTIND'.  'OPTIND' is initialized to 1 each time the
+     shell or a shell script is invoked.  When an option requires an
+     argument, 'getopts' places that argument into the variable
+     'OPTARG'.  The shell does not reset 'OPTIND' automatically; it must
+     be manually reset between multiple calls to 'getopts' within the
+     same shell invocation if a new set of parameters is to be used.
+
+     When the end of options is encountered, 'getopts' exits with a
+     return value greater than zero.  'OPTIND' is set to the index of
+     the first non-option argument, and NAME is set to '?'.
+
+     'getopts' normally parses the positional parameters, but if more
+     arguments are supplied as ARG values, 'getopts' parses those
+     instead.
+
+     'getopts' can report errors in two ways.  If the first character of
+     OPTSTRING is a colon, SILENT error reporting is used.  In normal
+     operation, diagnostic messages are printed when invalid options or
+     missing option arguments are encountered.  If the variable 'OPTERR'
+     is set to 0, no error messages will be displayed, even if the first
+     character of 'optstring' is not a colon.
+
+     If an invalid option is seen, 'getopts' places '?' into NAME and,
+     if not silent, prints an error message and unsets 'OPTARG'.  If
+     'getopts' is silent, the option character found is placed in
+     'OPTARG' and no diagnostic message is printed.
+
+     If a required argument is not found, and 'getopts' is not silent, a
+     question mark ('?') is placed in NAME, 'OPTARG' is unset, and a
+     diagnostic message is printed.  If 'getopts' is silent, then a
+     colon (':') is placed in NAME and 'OPTARG' is set to the option
+     character found.
+
+'hash'
+          hash [-r] [-p FILENAME] [-dt] [NAME]
+
+     Each time 'hash' is invoked, it remembers the full pathnames of the
+     commands specified as NAME arguments, so they need not be searched
+     for on subsequent invocations.  The commands are found by searching
+     through the directories listed in '$PATH'.  Any
+     previously-remembered pathname is discarded.  The '-p' option
+     inhibits the path search, and FILENAME is used as the location of
+     NAME.  The '-r' option causes the shell to forget all remembered
+     locations.  The '-d' option causes the shell to forget the
+     remembered location of each NAME.  If the '-t' option is supplied,
+     the full pathname to which each NAME corresponds is printed.  If
+     multiple NAME arguments are supplied with '-t', the NAME is printed
+     before the hashed full pathname.  The '-l' option causes output to
+     be displayed in a format that may be reused as input.  If no
+     arguments are given, or if only '-l' is supplied, information about
+     remembered commands is printed.  The return status is zero unless a
+     NAME is not found or an invalid option is supplied.
+
+'pwd'
+          pwd [-LP]
+
+     Print the absolute pathname of the current working directory.  If
+     the '-P' option is supplied, the pathname printed will not contain
+     symbolic links.  If the '-L' option is supplied, the pathname
+     printed may contain symbolic links.  The return status is zero
+     unless an error is encountered while determining the name of the
+     current directory or an invalid option is supplied.
+
+'readonly'
+          readonly [-aAf] [-p] [NAME[=VALUE]] ...
+
+     Mark each NAME as readonly.  The values of these names may not be
+     changed by subsequent assignment.  If the '-f' option is supplied,
+     each NAME refers to a shell function.  The '-a' option means each
+     NAME refers to an indexed array variable; the '-A' option means
+     each NAME refers to an associative array variable.  If both options
+     are supplied, '-A' takes precedence.  If no NAME arguments are
+     given, or if the '-p' option is supplied, a list of all readonly
+     names is printed.  The other options may be used to restrict the
+     output to a subset of the set of readonly names.  The '-p' option
+     causes output to be displayed in a format that may be reused as
+     input.  If a variable name is followed by =VALUE, the value of the
+     variable is set to VALUE.  The return status is zero unless an
+     invalid option is supplied, one of the NAME arguments is not a
+     valid shell variable or function name, or the '-f' option is
+     supplied with a name that is not a shell function.
+
+'return'
+          return [N]
+
+     Cause a shell function to stop executing and return the value N to
+     its caller.  If N is not supplied, the return value is the exit
+     status of the last command executed in the function.  If 'return'
+     is executed by a trap handler, the last command used to determine
+     the status is the last command executed before the trap handler.
+     If 'return' is executed during a 'DEBUG' trap, the last command
+     used to determine the status is the last command executed by the
+     trap handler before 'return' was invoked.  'return' may also be
+     used to terminate execution of a script being executed with the '.'
+     ('source') builtin, returning either N or the exit status of the
+     last command executed within the script as the exit status of the
+     script.  If N is supplied, the return value is its least
+     significant 8 bits.  Any command associated with the 'RETURN' trap
+     is executed before execution resumes after the function or script.
+     The return status is non-zero if 'return' is supplied a non-numeric
+     argument or is used outside a function and not during the execution
+     of a script by '.' or 'source'.
+
+'shift'
+          shift [N]
+
+     Shift the positional parameters to the left by N.  The positional
+     parameters from N+1 ... '$#' are renamed to '$1' ... '$#'-N.
+     Parameters represented by the numbers '$#' down to '$#'-N+1 are
+     unset.  N must be a non-negative number less than or equal to '$#'.
+     If N is zero or greater than '$#', the positional parameters are
+     not changed.  If N is not supplied, it is assumed to be 1.  The
+     return status is zero unless N is greater than '$#' or less than
+     zero, non-zero otherwise.
+
+'test'
+'['
+          test EXPR
+
+     Evaluate a conditional expression EXPR and return a status of 0
+     (true) or 1 (false).  Each operator and operand must be a separate
+     argument.  Expressions are composed of the primaries described
+     below in *note Bash Conditional Expressions::.  'test' does not
+     accept any options, nor does it accept and ignore an argument of
+     '--' as signifying the end of options.
+
+     When the '[' form is used, the last argument to the command must be
+     a ']'.
+
+     Expressions may be combined using the following operators, listed
+     in decreasing order of precedence.  The evaluation depends on the
+     number of arguments; see below.  Operator precedence is used when
+     there are five or more arguments.
+
+     '! EXPR'
+          True if EXPR is false.
+
+     '( EXPR )'
+          Returns the value of EXPR.  This may be used to override the
+          normal precedence of operators.
+
+     'EXPR1 -a EXPR2'
+          True if both EXPR1 and EXPR2 are true.
+
+     'EXPR1 -o EXPR2'
+          True if either EXPR1 or EXPR2 is true.
+
+     The 'test' and '[' builtins evaluate conditional expressions using
+     a set of rules based on the number of arguments.
+
+     0 arguments
+          The expression is false.
+
+     1 argument
+          The expression is true if, and only if, the argument is not
+          null.
+
+     2 arguments
+          If the first argument is '!', the expression is true if and
+          only if the second argument is null.  If the first argument is
+          one of the unary conditional operators (*note Bash Conditional
+          Expressions::), the expression is true if the unary test is
+          true.  If the first argument is not a valid unary operator,
+          the expression is false.
+
+     3 arguments
+          The following conditions are applied in the order listed.
+
+            1. If the second argument is one of the binary conditional
+               operators (*note Bash Conditional Expressions::), the
+               result of the expression is the result of the binary test
+               using the first and third arguments as operands.  The
+               '-a' and '-o' operators are considered binary operators
+               when there are three arguments.
+            2. If the first argument is '!', the value is the negation
+               of the two-argument test using the second and third
+               arguments.
+            3. If the first argument is exactly '(' and the third
+               argument is exactly ')', the result is the one-argument
+               test of the second argument.
+            4. Otherwise, the expression is false.
+
+     4 arguments
+          The following conditions are applied in the order listed.
+
+            1. If the first argument is '!', the result is the negation
+               of the three-argument expression composed of the
+               remaining arguments.
+            2. If the first argument is exactly '(' and the fourth
+               argument is exactly ')', the result is the two-argument
+               test of the second and third arguments.
+            3. Otherwise, the expression is parsed and evaluated
+               according to precedence using the rules listed above.
+
+     5 or more arguments
+          The expression is parsed and evaluated according to precedence
+          using the rules listed above.
+
+     When used with 'test' or '[', the '<' and '>' operators sort
+     lexicographically using ASCII ordering.
+
+'times'
+          times
+
+     Print out the user and system times used by the shell and its
+     children.  The return status is zero.
+
+'trap'
+          trap [-lp] [ARG] [SIGSPEC ...]
+
+     The commands in ARG are to be read and executed when the shell
+     receives signal SIGSPEC.  If ARG is absent (and there is a single
+     SIGSPEC) or equal to '-', each specified signal's disposition is
+     reset to the value it had when the shell was started.  If ARG is
+     the null string, then the signal specified by each SIGSPEC is
+     ignored by the shell and commands it invokes.  If ARG is not
+     present and '-p' has been supplied, the shell displays the trap
+     commands associated with each SIGSPEC.  If no arguments are
+     supplied, or only '-p' is given, 'trap' prints the list of commands
+     associated with each signal number in a form that may be reused as
+     shell input.  The '-l' option causes the shell to print a list of
+     signal names and their corresponding numbers.  Each SIGSPEC is
+     either a signal name or a signal number.  Signal names are case
+     insensitive and the 'SIG' prefix is optional.
+
+     If a SIGSPEC is '0' or 'EXIT', ARG is executed when the shell
+     exits.  If a SIGSPEC is 'DEBUG', the command ARG is executed before
+     every simple command, 'for' command, 'case' command, 'select'
+     command, every arithmetic 'for' command, and before the first
+     command executes in a shell function.  Refer to the description of
+     the 'extdebug' option to the 'shopt' builtin (*note The Shopt
+     Builtin::) for details of its effect on the 'DEBUG' trap.  If a
+     SIGSPEC is 'RETURN', the command ARG is executed each time a shell
+     function or a script executed with the '.' or 'source' builtins
+     finishes executing.
+
+     If a SIGSPEC is 'ERR', the command ARG is executed whenever a
+     pipeline (which may consist of a single simple command), a list, or
+     a compound command returns a non-zero exit status, subject to the
+     following conditions.  The 'ERR' trap is not executed if the failed
+     command is part of the command list immediately following an
+     'until' or 'while' keyword, part of the test following the 'if' or
+     'elif' reserved words, part of a command executed in a '&&' or '||'
+     list except the command following the final '&&' or '||', any
+     command in a pipeline but the last, or if the command's return
+     status is being inverted using '!'.  These are the same conditions
+     obeyed by the 'errexit' ('-e') option.
+
+     Signals ignored upon entry to the shell cannot be trapped or reset.
+     Trapped signals that are not being ignored are reset to their
+     original values in a subshell or subshell environment when one is
+     created.
+
+     The return status is zero unless a SIGSPEC does not specify a valid
+     signal.
+
+'umask'
+          umask [-p] [-S] [MODE]
+
+     Set the shell process's file creation mask to MODE.  If MODE begins
+     with a digit, it is interpreted as an octal number; if not, it is
+     interpreted as a symbolic mode mask similar to that accepted by the
+     'chmod' command.  If MODE is omitted, the current value of the mask
+     is printed.  If the '-S' option is supplied without a MODE
+     argument, the mask is printed in a symbolic format.  If the '-p'
+     option is supplied, and MODE is omitted, the output is in a form
+     that may be reused as input.  The return status is zero if the mode
+     is successfully changed or if no MODE argument is supplied, and
+     non-zero otherwise.
+
+     Note that when the mode is interpreted as an octal number, each
+     number of the umask is subtracted from '7'.  Thus, a umask of '022'
+     results in permissions of '755'.
+
+'unset'
+          unset [-fnv] [NAME]
+
+     Remove each variable or function NAME.  If the '-v' option is
+     given, each NAME refers to a shell variable and that variable is
+     removed.  If the '-f' option is given, the NAMEs refer to shell
+     functions, and the function definition is removed.  If the '-n'
+     option is supplied, and NAME is a variable with the 'nameref'
+     attribute, NAME will be unset rather than the variable it
+     references.  '-n' has no effect if the '-f' option is supplied.  If
+     no options are supplied, each NAME refers to a variable; if there
+     is no variable by that name, a function with that name, if any, is
+     unset.  Readonly variables and functions may not be unset.  Some
+     shell variables lose their special behavior if they are unset; such
+     behavior is noted in the description of the individual variables.
+     The return status is zero unless a NAME is readonly or may not be
+     unset.

+4.2 Bash Builtin Commands
+=========================
+
+This section describes builtin commands which are unique to or have been
+extended in Bash.  Some of these commands are specified in the POSIX
+standard.
+
+'alias'
+          alias [-p] [NAME[=VALUE] ...]
+
+     Without arguments or with the '-p' option, 'alias' prints the list
+     of aliases on the standard output in a form that allows them to be
+     reused as input.  If arguments are supplied, an alias is defined
+     for each NAME whose VALUE is given.  If no VALUE is given, the name
+     and value of the alias is printed.  Aliases are described in *note
+     Aliases::.
+
+'bind'
+          bind [-m KEYMAP] [-lpsvPSVX]
+          bind [-m KEYMAP] [-q FUNCTION] [-u FUNCTION] [-r KEYSEQ]
+          bind [-m KEYMAP] -f FILENAME
+          bind [-m KEYMAP] -x KEYSEQ:SHELL-COMMAND
+          bind [-m KEYMAP] KEYSEQ:FUNCTION-NAME
+          bind [-m KEYMAP] KEYSEQ:READLINE-COMMAND
+          bind READLINE-COMMAND-LINE
+
+     Display current Readline (*note Command Line Editing::) key and
+     function bindings, bind a key sequence to a Readline function or
+     macro, or set a Readline variable.  Each non-option argument is a
+     command as it would appear in a Readline initialization file (*note
+     Readline Init File::), but each binding or command must be passed
+     as a separate argument; e.g., '"\C-x\C-r":re-read-init-file'.
+
+     Options, if supplied, have the following meanings:
+
+     '-m KEYMAP'
+          Use KEYMAP as the keymap to be affected by the subsequent
+          bindings.  Acceptable KEYMAP names are 'emacs',
+          'emacs-standard', 'emacs-meta', 'emacs-ctlx', 'vi', 'vi-move',
+          'vi-command', and 'vi-insert'.  'vi' is equivalent to
+          'vi-command' ('vi-move' is also a synonym); 'emacs' is
+          equivalent to 'emacs-standard'.
+
+     '-l'
+          List the names of all Readline functions.
+
+     '-p'
+          Display Readline function names and bindings in such a way
+          that they can be used as input or in a Readline initialization
+          file.
+
+     '-P'
+          List current Readline function names and bindings.
+
+     '-v'
+          Display Readline variable names and values in such a way that
+          they can be used as input or in a Readline initialization
+          file.
+
+     '-V'
+          List current Readline variable names and values.
+
+     '-s'
+          Display Readline key sequences bound to macros and the strings
+          they output in such a way that they can be used as input or in
+          a Readline initialization file.
+
+     '-S'
+          Display Readline key sequences bound to macros and the strings
+          they output.
+
+     '-f FILENAME'
+          Read key bindings from FILENAME.
+
+     '-q FUNCTION'
+          Query about which keys invoke the named FUNCTION.
+
+     '-u FUNCTION'
+          Unbind all keys bound to the named FUNCTION.
+
+     '-r KEYSEQ'
+          Remove any current binding for KEYSEQ.
+
+     '-x KEYSEQ:SHELL-COMMAND'
+          Cause SHELL-COMMAND to be executed whenever KEYSEQ is entered.
+          When SHELL-COMMAND is executed, the shell sets the
+          'READLINE_LINE' variable to the contents of the Readline line
+          buffer and the 'READLINE_POINT' and 'READLINE_MARK' variables
+          to the current location of the insertion point and the saved
+          insertion point (the MARK), respectively.  The shell assigns
+          any numeric argument the user supplied to the
+          'READLINE_ARGUMENT' variable.  If there was no argument, that
+          variable is not set.  If the executed command changes the
+          value of any of 'READLINE_LINE', 'READLINE_POINT', or
+          'READLINE_MARK', those new values will be reflected in the
+          editing state.
+
+     '-X'
+          List all key sequences bound to shell commands and the
+          associated commands in a format that can be reused as input.
+
+     The return status is zero unless an invalid option is supplied or
+     an error occurs.
+
+'builtin'
+          builtin [SHELL-BUILTIN [ARGS]]
+
+     Run a shell builtin, passing it ARGS, and return its exit status.
+     This is useful when defining a shell function with the same name as
+     a shell builtin, retaining the functionality of the builtin within
+     the function.  The return status is non-zero if SHELL-BUILTIN is
+     not a shell builtin command.
+
+'caller'
+          caller [EXPR]
+
+     Returns the context of any active subroutine call (a shell function
+     or a script executed with the '.' or 'source' builtins).
+
+     Without EXPR, 'caller' displays the line number and source filename
+     of the current subroutine call.  If a non-negative integer is
+     supplied as EXPR, 'caller' displays the line number, subroutine
+     name, and source file corresponding to that position in the current
+     execution call stack.  This extra information may be used, for
+     example, to print a stack trace.  The current frame is frame 0.
+
+     The return value is 0 unless the shell is not executing a
+     subroutine call or EXPR does not correspond to a valid position in
+     the call stack.
+
+'command'
+          command [-pVv] COMMAND [ARGUMENTS ...]
+
+     Runs COMMAND with ARGUMENTS ignoring any shell function named
+     COMMAND.  Only shell builtin commands or commands found by
+     searching the 'PATH' are executed.  If there is a shell function
+     named 'ls', running 'command ls' within the function will execute
+     the external command 'ls' instead of calling the function
+     recursively.  The '-p' option means to use a default value for
+     'PATH' that is guaranteed to find all of the standard utilities.
+     The return status in this case is 127 if COMMAND cannot be found or
+     an error occurred, and the exit status of COMMAND otherwise.
+
+     If either the '-V' or '-v' option is supplied, a description of
+     COMMAND is printed.  The '-v' option causes a single word
+     indicating the command or file name used to invoke COMMAND to be
+     displayed; the '-V' option produces a more verbose description.  In
+     this case, the return status is zero if COMMAND is found, and
+     non-zero if not.
+
+'declare'
+          declare [-aAfFgiIlnrtux] [-p] [NAME[=VALUE] ...]
+
+     Declare variables and give them attributes.  If no NAMEs are given,
+     then display the values of variables instead.
+
+     The '-p' option will display the attributes and values of each
+     NAME.  When '-p' is used with NAME arguments, additional options,
+     other than '-f' and '-F', are ignored.
+
+     When '-p' is supplied without NAME arguments, 'declare' will
+     display the attributes and values of all variables having the
+     attributes specified by the additional options.  If no other
+     options are supplied with '-p', 'declare' will display the
+     attributes and values of all shell variables.  The '-f' option will
+     restrict the display to shell functions.
+
+     The '-F' option inhibits the display of function definitions; only
+     the function name and attributes are printed.  If the 'extdebug'
+     shell option is enabled using 'shopt' (*note The Shopt Builtin::),
+     the source file name and line number where each NAME is defined are
+     displayed as well.  '-F' implies '-f'.
+
+     The '-g' option forces variables to be created or modified at the
+     global scope, even when 'declare' is executed in a shell function.
+     It is ignored in all other cases.
+
+     The '-I' option causes local variables to inherit the attributes
+     (except the 'nameref' attribute) and value of any existing variable
+     with the same NAME at a surrounding scope.  If there is no existing
+     variable, the local variable is initially unset.
+
+     The following options can be used to restrict output to variables
+     with the specified attributes or to give variables attributes:
+
+     '-a'
+          Each NAME is an indexed array variable (*note Arrays::).
+
+     '-A'
+          Each NAME is an associative array variable (*note Arrays::).
+
+     '-f'
+          Use function names only.
+
+     '-i'
+          The variable is to be treated as an integer; arithmetic
+          evaluation (*note Shell Arithmetic::) is performed when the
+          variable is assigned a value.
+
+     '-l'
+          When the variable is assigned a value, all upper-case
+          characters are converted to lower-case.  The upper-case
+          attribute is disabled.
+
+     '-n'
+          Give each NAME the 'nameref' attribute, making it a name
+          reference to another variable.  That other variable is defined
+          by the value of NAME.  All references, assignments, and
+          attribute modifications to NAME, except for those using or
+          changing the '-n' attribute itself, are performed on the
+          variable referenced by NAME's value.  The nameref attribute
+          cannot be applied to array variables.
+
+     '-r'
+          Make NAMEs readonly.  These names cannot then be assigned
+          values by subsequent assignment statements or unset.
+
+     '-t'
+          Give each NAME the 'trace' attribute.  Traced functions
+          inherit the 'DEBUG' and 'RETURN' traps from the calling shell.
+          The trace attribute has no special meaning for variables.
+
+     '-u'
+          When the variable is assigned a value, all lower-case
+          characters are converted to upper-case.  The lower-case
+          attribute is disabled.
+
+     '-x'
+          Mark each NAME for export to subsequent commands via the
+          environment.
+
+     Using '+' instead of '-' turns off the attribute instead, with the
+     exceptions that '+a' and '+A' may not be used to destroy array
+     variables and '+r' will not remove the readonly attribute.  When
+     used in a function, 'declare' makes each NAME local, as with the
+     'local' command, unless the '-g' option is used.  If a variable
+     name is followed by =VALUE, the value of the variable is set to
+     VALUE.
+
+     When using '-a' or '-A' and the compound assignment syntax to
+     create array variables, additional attributes do not take effect
+     until subsequent assignments.
+
+     The return status is zero unless an invalid option is encountered,
+     an attempt is made to define a function using '-f foo=bar', an
+     attempt is made to assign a value to a readonly variable, an
+     attempt is made to assign a value to an array variable without
+     using the compound assignment syntax (*note Arrays::), one of the
+     NAMEs is not a valid shell variable name, an attempt is made to
+     turn off readonly status for a readonly variable, an attempt is
+     made to turn off array status for an array variable, or an attempt
+     is made to display a non-existent function with '-f'.
+
+'echo'
+          echo [-neE] [ARG ...]
+
+     Output the ARGs, separated by spaces, terminated with a newline.
+     The return status is 0 unless a write error occurs.  If '-n' is
+     specified, the trailing newline is suppressed.  If the '-e' option
+     is given, interpretation of the following backslash-escaped
+     characters is enabled.  The '-E' option disables the interpretation
+     of these escape characters, even on systems where they are
+     interpreted by default.  The 'xpg_echo' shell option may be used to
+     dynamically determine whether or not 'echo' expands these escape
+     characters by default.  'echo' does not interpret '--' to mean the
+     end of options.
+
+     'echo' interprets the following escape sequences:
+     '\a'
+          alert (bell)
+     '\b'
+          backspace
+     '\c'
+          suppress further output
+     '\e'
+     '\E'
+          escape
+     '\f'
+          form feed
+     '\n'
+          new line
+     '\r'
+          carriage return
+     '\t'
+          horizontal tab
+     '\v'
+          vertical tab
+     '\\'
+          backslash
+     '\0NNN'
+          the eight-bit character whose value is the octal value NNN
+          (zero to three octal digits)
+     '\xHH'
+          the eight-bit character whose value is the hexadecimal value
+          HH (one or two hex digits)
+     '\uHHHH'
+          the Unicode (ISO/IEC 10646) character whose value is the
+          hexadecimal value HHHH (one to four hex digits)
+     '\UHHHHHHHH'
+          the Unicode (ISO/IEC 10646) character whose value is the
+          hexadecimal value HHHHHHHH (one to eight hex digits)
+
+'enable'
+          enable [-a] [-dnps] [-f FILENAME] [NAME ...]
+
+     Enable and disable builtin shell commands.  Disabling a builtin
+     allows a disk command which has the same name as a shell builtin to
+     be executed without specifying a full pathname, even though the
+     shell normally searches for builtins before disk commands.  If '-n'
+     is used, the NAMEs become disabled.  Otherwise NAMEs are enabled.
+     For example, to use the 'test' binary found via '$PATH' instead of
+     the shell builtin version, type 'enable -n test'.
+
+     If the '-p' option is supplied, or no NAME arguments appear, a list
+     of shell builtins is printed.  With no other arguments, the list
+     consists of all enabled shell builtins.  The '-a' option means to
+     list each builtin with an indication of whether or not it is
+     enabled.
+
+     The '-f' option means to load the new builtin command NAME from
+     shared object FILENAME, on systems that support dynamic loading.
+     Bash will use the value of the 'BASH_LOADABLES_PATH' variable as a
+     colon-separated list of directories in which to search for
+     FILENAME.  The default is system-dependent.  The '-d' option will
+     delete a builtin loaded with '-f'.
+
+     If there are no options, a list of the shell builtins is displayed.
+     The '-s' option restricts 'enable' to the POSIX special builtins.
+     If '-s' is used with '-f', the new builtin becomes a special
+     builtin (*note Special Builtins::).
+
+     If no options are supplied and a NAME is not a shell builtin,
+     'enable' will attempt to load NAME from a shared object named NAME,
+     as if the command were 'enable -f NAME NAME'.
+
+     The return status is zero unless a NAME is not a shell builtin or
+     there is an error loading a new builtin from a shared object.
+
+'help'
+          help [-dms] [PATTERN]
+
+     Display helpful information about builtin commands.  If PATTERN is
+     specified, 'help' gives detailed help on all commands matching
+     PATTERN, otherwise a list of the builtins is printed.
+
+     Options, if supplied, have the following meanings:
+
+     '-d'
+          Display a short description of each PATTERN
+     '-m'
+          Display the description of each PATTERN in a manpage-like
+          format
+     '-s'
+          Display only a short usage synopsis for each PATTERN
+
+     The return status is zero unless no command matches PATTERN.
+
+'let'
+          let EXPRESSION [EXPRESSION ...]
+
+     The 'let' builtin allows arithmetic to be performed on shell
+     variables.  Each EXPRESSION is evaluated according to the rules
+     given below in *note Shell Arithmetic::.  If the last EXPRESSION
+     evaluates to 0, 'let' returns 1; otherwise 0 is returned.
+
+'local'
+          local [OPTION] NAME[=VALUE] ...
+
+     For each argument, a local variable named NAME is created, and
+     assigned VALUE.  The OPTION can be any of the options accepted by
+     'declare'.  'local' can only be used within a function; it makes
+     the variable NAME have a visible scope restricted to that function
+     and its children.  If NAME is '-', the set of shell options is made
+     local to the function in which 'local' is invoked: shell options
+     changed using the 'set' builtin inside the function are restored to
+     their original values when the function returns.  The restore is
+     effected as if a series of 'set' commands were executed to restore
+     the values that were in place before the function.  The return
+     status is zero unless 'local' is used outside a function, an
+     invalid NAME is supplied, or NAME is a readonly variable.
+
+'logout'
+          logout [N]
+
+     Exit a login shell, returning a status of N to the shell's parent.
+
+'mapfile'
+          mapfile [-d DELIM] [-n COUNT] [-O ORIGIN] [-s COUNT]
+              [-t] [-u FD] [-C CALLBACK] [-c QUANTUM] [ARRAY]
+
+     Read lines from the standard input into the indexed array variable
+     ARRAY, or from file descriptor FD if the '-u' option is supplied.
+     The variable 'MAPFILE' is the default ARRAY.  Options, if supplied,
+     have the following meanings:
+
+     '-d'
+          The first character of DELIM is used to terminate each input
+          line, rather than newline.  If DELIM is the empty string,
+          'mapfile' will terminate a line when it reads a NUL character.
+     '-n'
+          Copy at most COUNT lines.  If COUNT is 0, all lines are
+          copied.
+     '-O'
+          Begin assigning to ARRAY at index ORIGIN.  The default index
+          is 0.
+     '-s'
+          Discard the first COUNT lines read.
+     '-t'
+          Remove a trailing DELIM (default newline) from each line read.
+     '-u'
+          Read lines from file descriptor FD instead of the standard
+          input.
+     '-C'
+          Evaluate CALLBACK each time QUANTUM lines are read.  The '-c'
+          option specifies QUANTUM.
+     '-c'
+          Specify the number of lines read between each call to
+          CALLBACK.
+
+     If '-C' is specified without '-c', the default quantum is 5000.
+     When CALLBACK is evaluated, it is supplied the index of the next
+     array element to be assigned and the line to be assigned to that
+     element as additional arguments.  CALLBACK is evaluated after the
+     line is read but before the array element is assigned.
+
+     If not supplied with an explicit origin, 'mapfile' will clear ARRAY
+     before assigning to it.
+
+     'mapfile' returns successfully unless an invalid option or option
+     argument is supplied, ARRAY is invalid or unassignable, or ARRAY is
+     not an indexed array.
+
+'printf'
+          printf [-v VAR] FORMAT [ARGUMENTS]
+
+     Write the formatted ARGUMENTS to the standard output under the
+     control of the FORMAT.  The '-v' option causes the output to be
+     assigned to the variable VAR rather than being printed to the
+     standard output.
+
+     The FORMAT is a character string which contains three types of
+     objects: plain characters, which are simply copied to standard
+     output, character escape sequences, which are converted and copied
+     to the standard output, and format specifications, each of which
+     causes printing of the next successive ARGUMENT.  In addition to
+     the standard 'printf(1)' formats, 'printf' interprets the following
+     extensions:
+
+     '%b'
+          Causes 'printf' to expand backslash escape sequences in the
+          corresponding ARGUMENT in the same way as 'echo -e' (*note
+          Bash Builtins::).
+     '%q'
+          Causes 'printf' to output the corresponding ARGUMENT in a
+          format that can be reused as shell input.
+     '%Q'
+          like '%q', but applies any supplied precision to the ARGUMENT
+          before quoting it.
+     '%(DATEFMT)T'
+          Causes 'printf' to output the date-time string resulting from
+          using DATEFMT as a format string for 'strftime'(3).  The
+          corresponding ARGUMENT is an integer representing the number
+          of seconds since the epoch.  Two special argument values may
+          be used: -1 represents the current time, and -2 represents the
+          time the shell was invoked.  If no argument is specified,
+          conversion behaves as if -1 had been given.  This is an
+          exception to the usual 'printf' behavior.
+
+     The %b, %q, and %T directives all use the field width and precision
+     arguments from the format specification and write that many bytes
+     from (or use that wide a field for) the expanded argument, which
+     usually contains more characters than the original.
+
+     Arguments to non-string format specifiers are treated as C language
+     constants, except that a leading plus or minus sign is allowed, and
+     if the leading character is a single or double quote, the value is
+     the ASCII value of the following character.
+
+     The FORMAT is reused as necessary to consume all of the ARGUMENTS.
+     If the FORMAT requires more ARGUMENTS than are supplied, the extra
+     format specifications behave as if a zero value or null string, as
+     appropriate, had been supplied.  The return value is zero on
+     success, non-zero on failure.
+
+'read'
+          read [-ers] [-a ANAME] [-d DELIM] [-i TEXT] [-n NCHARS]
+              [-N NCHARS] [-p PROMPT] [-t TIMEOUT] [-u FD] [NAME ...]
+
+     One line is read from the standard input, or from the file
+     descriptor FD supplied as an argument to the '-u' option, split
+     into words as described above in *note Word Splitting::, and the
+     first word is assigned to the first NAME, the second word to the
+     second NAME, and so on.  If there are more words than names, the
+     remaining words and their intervening delimiters are assigned to
+     the last NAME.  If there are fewer words read from the input stream
+     than names, the remaining names are assigned empty values.  The
+     characters in the value of the 'IFS' variable are used to split the
+     line into words using the same rules the shell uses for expansion
+     (described above in *note Word Splitting::).  The backslash
+     character '\' may be used to remove any special meaning for the
+     next character read and for line continuation.
+
+     Options, if supplied, have the following meanings:
+
+     '-a ANAME'
+          The words are assigned to sequential indices of the array
+          variable ANAME, starting at 0.  All elements are removed from
+          ANAME before the assignment.  Other NAME arguments are
+          ignored.
+
+     '-d DELIM'
+          The first character of DELIM is used to terminate the input
+          line, rather than newline.  If DELIM is the empty string,
+          'read' will terminate a line when it reads a NUL character.
+
+     '-e'
+          Readline (*note Command Line Editing::) is used to obtain the
+          line.  Readline uses the current (or default, if line editing
+          was not previously active) editing settings, but uses
+          Readline's default filename completion.
+
+     '-i TEXT'
+          If Readline is being used to read the line, TEXT is placed
+          into the editing buffer before editing begins.
+
+     '-n NCHARS'
+          'read' returns after reading NCHARS characters rather than
+          waiting for a complete line of input, but honors a delimiter
+          if fewer than NCHARS characters are read before the delimiter.
+
+     '-N NCHARS'
+          'read' returns after reading exactly NCHARS characters rather
+          than waiting for a complete line of input, unless EOF is
+          encountered or 'read' times out.  Delimiter characters
+          encountered in the input are not treated specially and do not
+          cause 'read' to return until NCHARS characters are read.  The
+          result is not split on the characters in 'IFS'; the intent is
+          that the variable is assigned exactly the characters read
+          (with the exception of backslash; see the '-r' option below).
+
+     '-p PROMPT'
+          Display PROMPT, without a trailing newline, before attempting
+          to read any input.  The prompt is displayed only if input is
+          coming from a terminal.
+
+     '-r'
+          If this option is given, backslash does not act as an escape
+          character.  The backslash is considered to be part of the
+          line.  In particular, a backslash-newline pair may not then be
+          used as a line continuation.
+
+     '-s'
+          Silent mode.  If input is coming from a terminal, characters
+          are not echoed.
+
+     '-t TIMEOUT'
+          Cause 'read' to time out and return failure if a complete line
+          of input (or a specified number of characters) is not read
+          within TIMEOUT seconds.  TIMEOUT may be a decimal number with
+          a fractional portion following the decimal point.  This option
+          is only effective if 'read' is reading input from a terminal,
+          pipe, or other special file; it has no effect when reading
+          from regular files.  If 'read' times out, 'read' saves any
+          partial input read into the specified variable NAME.  If
+          TIMEOUT is 0, 'read' returns immediately, without trying to
+          read any data.  The exit status is 0 if input is available on
+          the specified file descriptor, or the read will return EOF,
+          non-zero otherwise.  The exit status is greater than 128 if
+          the timeout is exceeded.
+
+     '-u FD'
+          Read input from file descriptor FD.
+
+     If no NAMEs are supplied, the line read, without the ending
+     delimiter but otherwise unmodified, is assigned to the variable
+     'REPLY'.  The exit status is zero, unless end-of-file is
+     encountered, 'read' times out (in which case the status is greater
+     than 128), a variable assignment error (such as assigning to a
+     readonly variable) occurs, or an invalid file descriptor is
+     supplied as the argument to '-u'.
+
+'readarray'
+          readarray [-d DELIM] [-n COUNT] [-O ORIGIN] [-s COUNT]
+              [-t] [-u FD] [-C CALLBACK] [-c QUANTUM] [ARRAY]
+
+     Read lines from the standard input into the indexed array variable
+     ARRAY, or from file descriptor FD if the '-u' option is supplied.
+
+     A synonym for 'mapfile'.
+
+'source'
+          source FILENAME
+
+     A synonym for '.' (*note Bourne Shell Builtins::).
+
+'type'
+          type [-afptP] [NAME ...]
+
+     For each NAME, indicate how it would be interpreted if used as a
+     command name.
+
+     If the '-t' option is used, 'type' prints a single word which is
+     one of 'alias', 'function', 'builtin', 'file' or 'keyword', if NAME
+     is an alias, shell function, shell builtin, disk file, or shell
+     reserved word, respectively.  If the NAME is not found, then
+     nothing is printed, and 'type' returns a failure status.
+
+     If the '-p' option is used, 'type' either returns the name of the
+     disk file that would be executed, or nothing if '-t' would not
+     return 'file'.
+
+     The '-P' option forces a path search for each NAME, even if '-t'
+     would not return 'file'.
+
+     If a command is hashed, '-p' and '-P' print the hashed value, which
+     is not necessarily the file that appears first in '$PATH'.
+
+     If the '-a' option is used, 'type' returns all of the places that
+     contain an executable named FILE.  This includes aliases and
+     functions, if and only if the '-p' option is not also used.
+
+     If the '-f' option is used, 'type' does not attempt to find shell
+     functions, as with the 'command' builtin.
+
+     The return status is zero if all of the NAMEs are found, non-zero
+     if any are not found.
+
+'typeset'
+          typeset [-afFgrxilnrtux] [-p] [NAME[=VALUE] ...]
+
+     The 'typeset' command is supplied for compatibility with the Korn
+     shell.  It is a synonym for the 'declare' builtin command.
+
+'ulimit'
+          ulimit [-HS] -a
+          ulimit [-HS] [-bcdefiklmnpqrstuvxPRT] [LIMIT]
+
+     'ulimit' provides control over the resources available to processes
+     started by the shell, on systems that allow such control.  If an
+     option is given, it is interpreted as follows:
+
+     '-S'
+          Change and report the soft limit associated with a resource.
+
+     '-H'
+          Change and report the hard limit associated with a resource.
+
+     '-a'
+          All current limits are reported; no limits are set.
+
+     '-b'
+          The maximum socket buffer size.
+
+     '-c'
+          The maximum size of core files created.
+
+     '-d'
+          The maximum size of a process's data segment.
+
+     '-e'
+          The maximum scheduling priority ("nice").
+
+     '-f'
+          The maximum size of files written by the shell and its
+          children.
+
+     '-i'
+          The maximum number of pending signals.
+
+     '-k'
+          The maximum number of kqueues that may be allocated.
+
+     '-l'
+          The maximum size that may be locked into memory.
+
+     '-m'
+          The maximum resident set size (many systems do not honor this
+          limit).
+
+     '-n'
+          The maximum number of open file descriptors (most systems do
+          not allow this value to be set).
+
+     '-p'
+          The pipe buffer size.
+
+     '-q'
+          The maximum number of bytes in POSIX message queues.
+
+     '-r'
+          The maximum real-time scheduling priority.
+
+     '-s'
+          The maximum stack size.
+
+     '-t'
+          The maximum amount of cpu time in seconds.
+
+     '-u'
+          The maximum number of processes available to a single user.
+
+     '-v'
+          The maximum amount of virtual memory available to the shell,
+          and, on some systems, to its children.
+
+     '-x'
+          The maximum number of file locks.
+
+     '-P'
+          The maximum number of pseudoterminals.
+
+     '-R'
+          The maximum time a real-time process can run before blocking,
+          in microseconds.
+
+     '-T'
+          The maximum number of threads.
+
+     If LIMIT is given, and the '-a' option is not used, LIMIT is the
+     new value of the specified resource.  The special LIMIT values
+     'hard', 'soft', and 'unlimited' stand for the current hard limit,
+     the current soft limit, and no limit, respectively.  A hard limit
+     cannot be increased by a non-root user once it is set; a soft limit
+     may be increased up to the value of the hard limit.  Otherwise, the
+     current value of the soft limit for the specified resource is
+     printed, unless the '-H' option is supplied.  When more than one
+     resource is specified, the limit name and unit, if appropriate, are
+     printed before the value.  When setting new limits, if neither '-H'
+     nor '-S' is supplied, both the hard and soft limits are set.  If no
+     option is given, then '-f' is assumed.  Values are in 1024-byte
+     increments, except for '-t', which is in seconds; '-R', which is in
+     microseconds; '-p', which is in units of 512-byte blocks; '-P',
+     '-T', '-b', '-k', '-n' and '-u', which are unscaled values; and,
+     when in POSIX Mode (*note Bash POSIX Mode::), '-c' and '-f', which
+     are in 512-byte increments.
+
+     The return status is zero unless an invalid option or argument is
+     supplied, or an error occurs while setting a new limit.
+
+'unalias'
+          unalias [-a] [NAME ... ]
+
+     Remove each NAME from the list of aliases.  If '-a' is supplied,
+     all aliases are removed.  Aliases are described in *note Aliases::.

+
+4.3.1 The Set Builtin
+---------------------
+
+This builtin is so complicated that it deserves its own section.  'set'
+allows you to change the values of shell options and set the positional
+parameters, or to display the names and values of shell variables.
+
+'set'
+          set [-abefhkmnptuvxBCEHPT] [-o OPTION-NAME] [--] [-] [ARGUMENT ...]
+          set [+abefhkmnptuvxBCEHPT] [+o OPTION-NAME] [--] [-] [ARGUMENT ...]
+
+     If no options or arguments are supplied, 'set' displays the names
+     and values of all shell variables and functions, sorted according
+     to the current locale, in a format that may be reused as input for
+     setting or resetting the currently-set variables.  Read-only
+     variables cannot be reset.  In POSIX mode, only shell variables are
+     listed.
+
+     When options are supplied, they set or unset shell attributes.
+     Options, if specified, have the following meanings:
+
+     '-a'
+          Each variable or function that is created or modified is given
+          the export attribute and marked for export to the environment
+          of subsequent commands.
+
+     '-b'
+          Cause the status of terminated background jobs to be reported
+          immediately, rather than before printing the next primary
+          prompt.
+
+     '-e'
+          Exit immediately if a pipeline (*note Pipelines::), which may
+          consist of a single simple command (*note Simple Commands::),
+          a list (*note Lists::), or a compound command (*note Compound
+          Commands::) returns a non-zero status.  The shell does not
+          exit if the command that fails is part of the command list
+          immediately following a 'while' or 'until' keyword, part of
+          the test in an 'if' statement, part of any command executed in
+          a '&&' or '||' list except the command following the final
+          '&&' or '||', any command in a pipeline but the last, or if
+          the command's return status is being inverted with '!'.  If a
+          compound command other than a subshell returns a non-zero
+          status because a command failed while '-e' was being ignored,
+          the shell does not exit.  A trap on 'ERR', if set, is executed
+          before the shell exits.
+
+          This option applies to the shell environment and each subshell
+          environment separately (*note Command Execution
+          Environment::), and may cause subshells to exit before
+          executing all the commands in the subshell.
+
+          If a compound command or shell function executes in a context
+          where '-e' is being ignored, none of the commands executed
+          within the compound command or function body will be affected
+          by the '-e' setting, even if '-e' is set and a command returns
+          a failure status.  If a compound command or shell function
+          sets '-e' while executing in a context where '-e' is ignored,
+          that setting will not have any effect until the compound
+          command or the command containing the function call completes.
+
+     '-f'
+          Disable filename expansion (globbing).
+
+     '-h'
+          Locate and remember (hash) commands as they are looked up for
+          execution.  This option is enabled by default.
+
+     '-k'
+          All arguments in the form of assignment statements are placed
+          in the environment for a command, not just those that precede
+          the command name.
+
+     '-m'
+          Job control is enabled (*note Job Control::).  All processes
+          run in a separate process group.  When a background job
+          completes, the shell prints a line containing its exit status.
+
+     '-n'
+          Read commands but do not execute them.  This may be used to
+          check a script for syntax errors.  This option is ignored by
+          interactive shells.
+
+     '-o OPTION-NAME'
+
+          Set the option corresponding to OPTION-NAME:
+
+          'allexport'
+               Same as '-a'.
+
+          'braceexpand'
+               Same as '-B'.
+
+          'emacs'
+               Use an 'emacs'-style line editing interface (*note
+               Command Line Editing::).  This also affects the editing
+               interface used for 'read -e'.
+
+          'errexit'
+               Same as '-e'.
+
+          'errtrace'
+               Same as '-E'.
+
+          'functrace'
+               Same as '-T'.
+
+          'hashall'
+               Same as '-h'.
+
+          'histexpand'
+               Same as '-H'.
+
+          'history'
+               Enable command history, as described in *note Bash
+               History Facilities::.  This option is on by default in
+               interactive shells.
+
+          'ignoreeof'
+               An interactive shell will not exit upon reading EOF.
+
+          'keyword'
+               Same as '-k'.
+
+          'monitor'
+               Same as '-m'.
+
+          'noclobber'
+               Same as '-C'.
+
+          'noexec'
+               Same as '-n'.
+
+          'noglob'
+               Same as '-f'.
+
+          'nolog'
+               Currently ignored.
+
+          'notify'
+               Same as '-b'.
+
+          'nounset'
+               Same as '-u'.
+
+          'onecmd'
+               Same as '-t'.
+
+          'physical'
+               Same as '-P'.
+
+          'pipefail'
+               If set, the return value of a pipeline is the value of
+               the last (rightmost) command to exit with a non-zero
+               status, or zero if all commands in the pipeline exit
+               successfully.  This option is disabled by default.
+
+          'posix'
+               Change the behavior of Bash where the default operation
+               differs from the POSIX standard to match the standard
+               (*note Bash POSIX Mode::).  This is intended to make Bash
+               behave as a strict superset of that standard.
+
+          'privileged'
+               Same as '-p'.
+
+          'verbose'
+               Same as '-v'.
+
+          'vi'
+               Use a 'vi'-style line editing interface.  This also
+               affects the editing interface used for 'read -e'.
+
+          'xtrace'
+               Same as '-x'.
+
+     '-p'
+          Turn on privileged mode.  In this mode, the '$BASH_ENV' and
+          '$ENV' files are not processed, shell functions are not
+          inherited from the environment, and the 'SHELLOPTS',
+          'BASHOPTS', 'CDPATH' and 'GLOBIGNORE' variables, if they
+          appear in the environment, are ignored.  If the shell is
+          started with the effective user (group) id not equal to the
+          real user (group) id, and the '-p' option is not supplied,
+          these actions are taken and the effective user id is set to
+          the real user id.  If the '-p' option is supplied at startup,
+          the effective user id is not reset.  Turning this option off
+          causes the effective user and group ids to be set to the real
+          user and group ids.
+
+     '-r'
+          Enable restricted shell mode.  This option cannot be unset
+          once it has been set.
+
+     '-t'
+          Exit after reading and executing one command.
+
+     '-u'
+          Treat unset variables and parameters other than the special
+          parameters '@' or '*', or array variables subscripted with '@'
+          or '*', as an error when performing parameter expansion.  An
+          error message will be written to the standard error, and a
+          non-interactive shell will exit.
+
+     '-v'
+          Print shell input lines as they are read.
+
+     '-x'
+          Print a trace of simple commands, 'for' commands, 'case'
+          commands, 'select' commands, and arithmetic 'for' commands and
+          their arguments or associated word lists after they are
+          expanded and before they are executed.  The value of the 'PS4'
+          variable is expanded and the resultant value is printed before
+          the command and its expanded arguments.
+
+     '-B'
+          The shell will perform brace expansion (*note Brace
+          Expansion::).  This option is on by default.
+
+     '-C'
+          Prevent output redirection using '>', '>&', and '<>' from
+          overwriting existing files.
+
+     '-E'
+          If set, any trap on 'ERR' is inherited by shell functions,
+          command substitutions, and commands executed in a subshell
+          environment.  The 'ERR' trap is normally not inherited in such
+          cases.
+
+     '-H'
+          Enable '!' style history substitution (*note History
+          Interaction::).  This option is on by default for interactive
+          shells.
+
+     '-P'
+          If set, do not resolve symbolic links when performing commands
+          such as 'cd' which change the current directory.  The physical
+          directory is used instead.  By default, Bash follows the
+          logical chain of directories when performing commands which
+          change the current directory.
+
+          For example, if '/usr/sys' is a symbolic link to
+          '/usr/local/sys' then:
+               $ cd /usr/sys; echo $PWD
+               /usr/sys
+               $ cd ..; pwd
+               /usr
+
+          If 'set -P' is on, then:
+               $ cd /usr/sys; echo $PWD
+               /usr/local/sys
+               $ cd ..; pwd
+               /usr/local
+
+     '-T'
+          If set, any trap on 'DEBUG' and 'RETURN' are inherited by
+          shell functions, command substitutions, and commands executed
+          in a subshell environment.  The 'DEBUG' and 'RETURN' traps are
+          normally not inherited in such cases.
+
+     '--'
+          If no arguments follow this option, then the positional
+          parameters are unset.  Otherwise, the positional parameters
+          are set to the ARGUMENTS, even if some of them begin with a
+          '-'.
+
+     '-'
+          Signal the end of options, cause all remaining ARGUMENTS to be
+          assigned to the positional parameters.  The '-x' and '-v'
+          options are turned off.  If there are no arguments, the
+          positional parameters remain unchanged.
+
+     Using '+' rather than '-' causes these options to be turned off.
+     The options can also be used upon invocation of the shell.  The
+     current set of options may be found in '$-'.
+
+     The remaining N ARGUMENTS are positional parameters and are
+     assigned, in order, to '$1', '$2', ... '$N'.  The special parameter
+     '#' is set to N.
+
+     The return status is always zero unless an invalid option is
+     supplied.

+
+4.3.2 The Shopt Builtin
+-----------------------
+
+This builtin allows you to change additional shell optional behavior.
+
+'shopt'
+          shopt [-pqsu] [-o] [OPTNAME ...]
+
+     Toggle the values of settings controlling optional shell behavior.
+     The settings can be either those listed below, or, if the '-o'
+     option is used, those available with the '-o' option to the 'set'
+     builtin command (*note The Set Builtin::).  With no options, or
+     with the '-p' option, a list of all settable options is displayed,
+     with an indication of whether or not each is set; if OPTNAMEs are
+     supplied, the output is restricted to those options.  The '-p'
+     option causes output to be displayed in a form that may be reused
+     as input.  Other options have the following meanings:
+
+     '-s'
+          Enable (set) each OPTNAME.
+
+     '-u'
+          Disable (unset) each OPTNAME.
+
+     '-q'
+          Suppresses normal output; the return status indicates whether
+          the OPTNAME is set or unset.  If multiple OPTNAME arguments
+          are given with '-q', the return status is zero if all OPTNAMEs
+          are enabled; non-zero otherwise.
+
+     '-o'
+          Restricts the values of OPTNAME to be those defined for the
+          '-o' option to the 'set' builtin (*note The Set Builtin::).
+
+     If either '-s' or '-u' is used with no OPTNAME arguments, 'shopt'
+     shows only those options which are set or unset, respectively.
+
+     Unless otherwise noted, the 'shopt' options are disabled (off) by
+     default.
+
+     The return status when listing options is zero if all OPTNAMEs are
+     enabled, non-zero otherwise.  When setting or unsetting options,
+     the return status is zero unless an OPTNAME is not a valid shell
+     option.
+
+     The list of 'shopt' options is:
+
+     'assoc_expand_once'
+          If set, the shell suppresses multiple evaluation of
+          associative array subscripts during arithmetic expression
+          evaluation, while executing builtins that can perform variable
+          assignments, and while executing builtins that perform array
+          dereferencing.
+
+     'autocd'
+          If set, a command name that is the name of a directory is
+          executed as if it were the argument to the 'cd' command.  This
+          option is only used by interactive shells.
+
+     'cdable_vars'
+          If this is set, an argument to the 'cd' builtin command that
+          is not a directory is assumed to be the name of a variable
+          whose value is the directory to change to.
+
+     'cdspell'
+          If set, minor errors in the spelling of a directory component
+          in a 'cd' command will be corrected.  The errors checked for
+          are transposed characters, a missing character, and a
+          character too many.  If a correction is found, the corrected
+          path is printed, and the command proceeds.  This option is
+          only used by interactive shells.
+
+     'checkhash'
+          If this is set, Bash checks that a command found in the hash
+          table exists before trying to execute it.  If a hashed command
+          no longer exists, a normal path search is performed.
+
+     'checkjobs'
+          If set, Bash lists the status of any stopped and running jobs
+          before exiting an interactive shell.  If any jobs are running,
+          this causes the exit to be deferred until a second exit is
+          attempted without an intervening command (*note Job
+          Control::).  The shell always postpones exiting if any jobs
+          are stopped.
+
+     'checkwinsize'
+          If set, Bash checks the window size after each external
+          (non-builtin) command and, if necessary, updates the values of
+          'LINES' and 'COLUMNS'.  This option is enabled by default.
+
+     'cmdhist'
+          If set, Bash attempts to save all lines of a multiple-line
+          command in the same history entry.  This allows easy
+          re-editing of multi-line commands.  This option is enabled by
+          default, but only has an effect if command history is enabled
+          (*note Bash History Facilities::).
+
+     'compat31'
+     'compat32'
+     'compat40'
+     'compat41'
+     'compat42'
+     'compat43'
+     'compat44'
+          These control aspects of the shell's compatibility mode (*note
+          Shell Compatibility Mode::).
+
+     'complete_fullquote'
+          If set, Bash quotes all shell metacharacters in filenames and
+          directory names when performing completion.  If not set, Bash
+          removes metacharacters such as the dollar sign from the set of
+          characters that will be quoted in completed filenames when
+          these metacharacters appear in shell variable references in
+          words to be completed.  This means that dollar signs in
+          variable names that expand to directories will not be quoted;
+          however, any dollar signs appearing in filenames will not be
+          quoted, either.  This is active only when bash is using
+          backslashes to quote completed filenames.  This variable is
+          set by default, which is the default Bash behavior in versions
+          through 4.2.
+
+     'direxpand'
+          If set, Bash replaces directory names with the results of word
+          expansion when performing filename completion.  This changes
+          the contents of the Readline editing buffer.  If not set, Bash
+          attempts to preserve what the user typed.
+
+     'dirspell'
+          If set, Bash attempts spelling correction on directory names
+          during word completion if the directory name initially
+          supplied does not exist.
+
+     'dotglob'
+          If set, Bash includes filenames beginning with a '.'  in the
+          results of filename expansion.  The filenames '.' and '..'
+          must always be matched explicitly, even if 'dotglob' is set.
+
+     'execfail'
+          If this is set, a non-interactive shell will not exit if it
+          cannot execute the file specified as an argument to the 'exec'
+          builtin command.  An interactive shell does not exit if 'exec'
+          fails.
+
+     'expand_aliases'
+          If set, aliases are expanded as described below under Aliases,
+          *note Aliases::.  This option is enabled by default for
+          interactive shells.
+
+     'extdebug'
+          If set at shell invocation, or in a shell startup file,
+          arrange to execute the debugger profile before the shell
+          starts, identical to the '--debugger' option.  If set after
+          invocation, behavior intended for use by debuggers is enabled:
+
+            1. The '-F' option to the 'declare' builtin (*note Bash
+               Builtins::) displays the source file name and line number
+               corresponding to each function name supplied as an
+               argument.
+
+            2. If the command run by the 'DEBUG' trap returns a non-zero
+               value, the next command is skipped and not executed.
+
+            3. If the command run by the 'DEBUG' trap returns a value of
+               2, and the shell is executing in a subroutine (a shell
+               function or a shell script executed by the '.' or
+               'source' builtins), the shell simulates a call to
+               'return'.
+
+            4. 'BASH_ARGC' and 'BASH_ARGV' are updated as described in
+               their descriptions (*note Bash Variables::).
+
+            5. Function tracing is enabled: command substitution, shell
+               functions, and subshells invoked with '( COMMAND )'
+               inherit the 'DEBUG' and 'RETURN' traps.
+
+            6. Error tracing is enabled: command substitution, shell
+               functions, and subshells invoked with '( COMMAND )'
+               inherit the 'ERR' trap.
+
+     'extglob'
+          If set, the extended pattern matching features described above
+          (*note Pattern Matching::) are enabled.
+
+     'extquote'
+          If set, '$'STRING'' and '$"STRING"' quoting is performed
+          within '${PARAMETER}' expansions enclosed in double quotes.
+          This option is enabled by default.
+
+     'failglob'
+          If set, patterns which fail to match filenames during filename
+          expansion result in an expansion error.
+
+     'force_fignore'
+          If set, the suffixes specified by the 'FIGNORE' shell variable
+          cause words to be ignored when performing word completion even
+          if the ignored words are the only possible completions.  *Note
+          Bash Variables::, for a description of 'FIGNORE'.  This option
+          is enabled by default.
+
+     'globasciiranges'
+          If set, range expressions used in pattern matching bracket
+          expressions (*note Pattern Matching::) behave as if in the
+          traditional C locale when performing comparisons.  That is,
+          the current locale's collating sequence is not taken into
+          account, so 'b' will not collate between 'A' and 'B', and
+          upper-case and lower-case ASCII characters will collate
+          together.
+
+     'globskipdots'
+          If set, filename expansion will never match the filenames '.'
+          and '..', even if the pattern begins with a '.'.  This option
+          is enabled by default.
+
+     'globstar'
+          If set, the pattern '**' used in a filename expansion context
+          will match all files and zero or more directories and
+          subdirectories.  If the pattern is followed by a '/', only
+          directories and subdirectories match.
+
+     'gnu_errfmt'
+          If set, shell error messages are written in the standard GNU
+          error message format.
+
+     'histappend'
+          If set, the history list is appended to the file named by the
+          value of the 'HISTFILE' variable when the shell exits, rather
+          than overwriting the file.
+
+     'histreedit'
+          If set, and Readline is being used, a user is given the
+          opportunity to re-edit a failed history substitution.
+
+     'histverify'
+          If set, and Readline is being used, the results of history
+          substitution are not immediately passed to the shell parser.
+          Instead, the resulting line is loaded into the Readline
+          editing buffer, allowing further modification.
+
+     'hostcomplete'
+          If set, and Readline is being used, Bash will attempt to
+          perform hostname completion when a word containing a '@' is
+          being completed (*note Commands For Completion::).  This
+          option is enabled by default.
+
+     'huponexit'
+          If set, Bash will send 'SIGHUP' to all jobs when an
+          interactive login shell exits (*note Signals::).
+
+     'inherit_errexit'
+          If set, command substitution inherits the value of the
+          'errexit' option, instead of unsetting it in the subshell
+          environment.  This option is enabled when POSIX mode is
+          enabled.
+
+     'interactive_comments'
+          Allow a word beginning with '#' to cause that word and all
+          remaining characters on that line to be ignored in an
+          interactive shell.  This option is enabled by default.
+
+     'lastpipe'
+          If set, and job control is not active, the shell runs the last
+          command of a pipeline not executed in the background in the
+          current shell environment.
+
+     'lithist'
+          If enabled, and the 'cmdhist' option is enabled, multi-line
+          commands are saved to the history with embedded newlines
+          rather than using semicolon separators where possible.
+
+     'localvar_inherit'
+          If set, local variables inherit the value and attributes of a
+          variable of the same name that exists at a previous scope
+          before any new value is assigned.  The 'nameref' attribute is
+          not inherited.
+
+     'localvar_unset'
+          If set, calling 'unset' on local variables in previous
+          function scopes marks them so subsequent lookups find them
+          unset until that function returns.  This is identical to the
+          behavior of unsetting local variables at the current function
+          scope.
+
+     'login_shell'
+          The shell sets this option if it is started as a login shell
+          (*note Invoking Bash::).  The value may not be changed.
+
+     'mailwarn'
+          If set, and a file that Bash is checking for mail has been
+          accessed since the last time it was checked, the message '"The
+          mail in MAILFILE has been read"' is displayed.
+
+     'no_empty_cmd_completion'
+          If set, and Readline is being used, Bash will not attempt to
+          search the 'PATH' for possible completions when completion is
+          attempted on an empty line.
+
+     'nocaseglob'
+          If set, Bash matches filenames in a case-insensitive fashion
+          when performing filename expansion.
+
+     'nocasematch'
+          If set, Bash matches patterns in a case-insensitive fashion
+          when performing matching while executing 'case' or '[['
+          conditional commands (*note Conditional Constructs::, when
+          performing pattern substitution word expansions, or when
+          filtering possible completions as part of programmable
+          completion.
+
+     'noexpand_translation'
+          If set, Bash encloses the translated results of $"..."
+          quoting in single quotes instead of double quotes.  If the
+          string is not translated, this has no effect.
+
+     'nullglob'
+          If set, Bash allows filename patterns which match no files to
+          expand to a null string, rather than themselves.
+
+     'patsub_replacement'
+          If set, Bash expands occurrences of '&' in the replacement
+          string of pattern substitution to the text matched by the
+          pattern, as described above (*note Shell Parameter
+          Expansion::).  This option is enabled by default.
+
+     'progcomp'
+          If set, the programmable completion facilities (*note
+          Programmable Completion::) are enabled.  This option is
+          enabled by default.
+
+     'progcomp_alias'
+          If set, and programmable completion is enabled, Bash treats a
+          command name that doesn't have any completions as a possible
+          alias and attempts alias expansion.  If it has an alias, Bash
+          attempts programmable completion using the command word
+          resulting from the expanded alias.
+
+     'promptvars'
+          If set, prompt strings undergo parameter expansion, command
+          substitution, arithmetic expansion, and quote removal after
+          being expanded as described below (*note Controlling the
+          Prompt::).  This option is enabled by default.
+
+     'restricted_shell'
+          The shell sets this option if it is started in restricted mode
+          (*note The Restricted Shell::).  The value may not be changed.
+          This is not reset when the startup files are executed,
+          allowing the startup files to discover whether or not a shell
+          is restricted.
+
+     'shift_verbose'
+          If this is set, the 'shift' builtin prints an error message
+          when the shift count exceeds the number of positional
+          parameters.
+
+     'sourcepath'
+          If set, the '.' ('source') builtin uses the value of 'PATH' to
+          find the directory containing the file supplied as an
+          argument.  This option is enabled by default.
+
+     'varredir_close'
+          If set, the shell automatically closes file descriptors
+          assigned using the '{varname}' redirection syntax (*note
+          Redirections::) instead of leaving them open when the command
+          completes.
+
+     'xpg_echo'
+          If set, the 'echo' builtin expands backslash-escape sequences
+          by default.

+
+4.4 Special Builtins
+====================
+
+For historical reasons, the POSIX standard has classified several
+builtin commands as _special_.  When Bash is executing in POSIX mode,
+the special builtins differ from other builtin commands in three
+respects:
+
+  1. Special builtins are found before shell functions during command
+     lookup.
+
+  2. If a special builtin returns an error status, a non-interactive
+     shell exits.
+
+  3. Assignment statements preceding the command stay in effect in the
+     shell environment after the command completes.
+
+   When Bash is not executing in POSIX mode, these builtins behave no
+differently than the rest of the Bash builtin commands.  The Bash POSIX
+mode is described in *note Bash POSIX Mode::.
+
+   These are the POSIX special builtins:
+     break : . continue eval exec exit export readonly return set
+     shift trap unset

+				as the Bourne Shell.
+* Bash Variables::		List of variables that exist in Bash.
+
+This chapter describes the shell variables that Bash uses.  Bash
+automatically assigns default values to a number of variables.
+
+
+File: bashref.info,  Node: Bourne Shell Variables,  Next: Bash Variables,  Up: Shell Variables
+
+5.1 Bourne Shell Variables
+==========================
+
+Bash uses certain shell variables in the same way as the Bourne shell.
+In some cases, Bash assigns a default value to the variable.
+
+'CDPATH'
+     A colon-separated list of directories used as a search path for the
+     'cd' builtin command.
+
+'HOME'
+     The current user's home directory; the default for the 'cd' builtin
+     command.  The value of this variable is also used by tilde
+     expansion (*note Tilde Expansion::).
+
+'IFS'
+     A list of characters that separate fields; used when the shell
+     splits words as part of expansion.
+
+'MAIL'
+     If this parameter is set to a filename or directory name and the
+     'MAILPATH' variable is not set, Bash informs the user of the
+     arrival of mail in the specified file or Maildir-format directory.
+
+'MAILPATH'
+     A colon-separated list of filenames which the shell periodically
+     checks for new mail.  Each list entry can specify the message that
+     is printed when new mail arrives in the mail file by separating the
+     filename from the message with a '?'.  When used in the text of the
+     message, '$_' expands to the name of the current mail file.
+
+'OPTARG'
+     The value of the last option argument processed by the 'getopts'
+     builtin.
+
+'OPTIND'
+     The index of the last option argument processed by the 'getopts'
+     builtin.
+
+'PATH'
+     A colon-separated list of directories in which the shell looks for
+     commands.  A zero-length (null) directory name in the value of
+     'PATH' indicates the current directory.  A null directory name may
+     appear as two adjacent colons, or as an initial or trailing colon.
+
+'PS1'
+     The primary prompt string.  The default value is '\s-\v\$ '.  *Note
+     Controlling the Prompt::, for the complete list of escape sequences
+     that are expanded before 'PS1' is displayed.
+
+'PS2'
+     The secondary prompt string.  The default value is '> '.  'PS2' is
+     expanded in the same way as 'PS1' before being displayed.
+
+
+File: bashref.info,  Node: Bash Variables,  Prev: Bourne Shell Variables,  Up: Shell Variables
+
+5.2 Bash Variables
+==================
+
+These variables are set or used by Bash, but other shells do not
+normally treat them specially.
+
+   A few variables used by Bash are described in different chapters:
+variables for controlling the job control facilities (*note Job Control
+Variables::).
+
+'_'
+     ($_, an underscore.)  At shell startup, set to the pathname used to
+     invoke the shell or shell script being executed as passed in the
+     environment or argument list.  Subsequently, expands to the last
+     argument to the previous simple command executed in the foreground,
+     after expansion.  Also set to the full pathname used to invoke each
+     command executed and placed in the environment exported to that
+     command.  When checking mail, this parameter holds the name of the
+     mail file.
+
+'BASH'
+     The full pathname used to execute the current instance of Bash.
+
+'BASHOPTS'
+     A colon-separated list of enabled shell options.  Each word in the
+     list is a valid argument for the '-s' option to the 'shopt' builtin
+     command (*note The Shopt Builtin::).  The options appearing in
+     'BASHOPTS' are those reported as 'on' by 'shopt'.  If this variable
+     is in the environment when Bash starts up, each shell option in the
+     list will be enabled before reading any startup files.  This
+     variable is readonly.
+
+'BASHPID'
+     Expands to the process ID of the current Bash process.  This
+     differs from '$$' under certain circumstances, such as subshells
+     that do not require Bash to be re-initialized.  Assignments to
+     'BASHPID' have no effect.  If 'BASHPID' is unset, it loses its
+     special properties, even if it is subsequently reset.
+
+'BASH_ALIASES'
+     An associative array variable whose members correspond to the
+     internal list of aliases as maintained by the 'alias' builtin.
+     (*note Bourne Shell Builtins::).  Elements added to this array
+     appear in the alias list; however, unsetting array elements
+     currently does not cause aliases to be removed from the alias list.
+     If 'BASH_ALIASES' is unset, it loses its special properties, even
+     if it is subsequently reset.
+
+'BASH_ARGC'
+     An array variable whose values are the number of parameters in each
+     frame of the current bash execution call stack.  The number of
+     parameters to the current subroutine (shell function or script
+     executed with '.' or 'source') is at the top of the stack.  When a
+     subroutine is executed, the number of parameters passed is pushed
+     onto 'BASH_ARGC'.  The shell sets 'BASH_ARGC' only when in extended
+     debugging mode (see *note The Shopt Builtin:: for a description of
+     the 'extdebug' option to the 'shopt' builtin).  Setting 'extdebug'
+     after the shell has started to execute a script, or referencing
+     this variable when 'extdebug' is not set, may result in
+     inconsistent values.
+
+'BASH_ARGV'
+     An array variable containing all of the parameters in the current
+     bash execution call stack.  The final parameter of the last
+     subroutine call is at the top of the stack; the first parameter of
+     the initial call is at the bottom.  When a subroutine is executed,
+     the parameters supplied are pushed onto 'BASH_ARGV'.  The shell
+     sets 'BASH_ARGV' only when in extended debugging mode (see *note
+     The Shopt Builtin:: for a description of the 'extdebug' option to
+     the 'shopt' builtin).  Setting 'extdebug' after the shell has
+     started to execute a script, or referencing this variable when
+     'extdebug' is not set, may result in inconsistent values.
+
+'BASH_ARGV0'
+     When referenced, this variable expands to the name of the shell or
+     shell script (identical to '$0'; *Note Special Parameters::, for
+     the description of special parameter 0).  Assignment to
+     'BASH_ARGV0' causes the value assigned to also be assigned to '$0'.
+     If 'BASH_ARGV0' is unset, it loses its special properties, even if
+     it is subsequently reset.
+
+'BASH_CMDS'
+     An associative array variable whose members correspond to the
+     internal hash table of commands as maintained by the 'hash' builtin
+     (*note Bourne Shell Builtins::).  Elements added to this array
+     appear in the hash table; however, unsetting array elements
+     currently does not cause command names to be removed from the hash
+     table.  If 'BASH_CMDS' is unset, it loses its special properties,
+     even if it is subsequently reset.
+
+'BASH_COMMAND'
+     The command currently being executed or about to be executed,
+     unless the shell is executing a command as the result of a trap, in
+     which case it is the command executing at the time of the trap.  If
+     'BASH_COMMAND' is unset, it loses its special properties, even if
+     it is subsequently reset.
+
+'BASH_COMPAT'
+     The value is used to set the shell's compatibility level.  *Note
+     Shell Compatibility Mode::, for a description of the various
+     compatibility levels and their effects.  The value may be a decimal
+     number (e.g., 4.2) or an integer (e.g., 42) corresponding to the
+     desired compatibility level.  If 'BASH_COMPAT' is unset or set to
+     the empty string, the compatibility level is set to the default for
+     the current version.  If 'BASH_COMPAT' is set to a value that is
+     not one of the valid compatibility levels, the shell prints an
+     error message and sets the compatibility level to the default for
+     the current version.  The valid values correspond to the
+     compatibility levels described below (*note Shell Compatibility
+     Mode::).  For example, 4.2 and 42 are valid values that correspond
+     to the 'compat42' 'shopt' option and set the compatibility level to
+     42.  The current version is also a valid value.
+
+'BASH_ENV'
+     If this variable is set when Bash is invoked to execute a shell
+     script, its value is expanded and used as the name of a startup
+     file to read before executing the script.  *Note Bash Startup
+     Files::.
+
+'BASH_EXECUTION_STRING'
+     The command argument to the '-c' invocation option.
+
+'BASH_LINENO'
+     An array variable whose members are the line numbers in source
+     files where each corresponding member of 'FUNCNAME' was invoked.
+     '${BASH_LINENO[$i]}' is the line number in the source file
+     ('${BASH_SOURCE[$i+1]}') where '${FUNCNAME[$i]}' was called (or
+     '${BASH_LINENO[$i-1]}' if referenced within another shell
+     function).  Use 'LINENO' to obtain the current line number.
+
+'BASH_LOADABLES_PATH'
+     A colon-separated list of directories in which the shell looks for
+     dynamically loadable builtins specified by the 'enable' command.
+
+'BASH_REMATCH'
+     An array variable whose members are assigned by the '=~' binary
+     operator to the '[[' conditional command (*note Conditional
+     Constructs::).  The element with index 0 is the portion of the
+     string matching the entire regular expression.  The element with
+     index N is the portion of the string matching the Nth parenthesized
+     subexpression.
+
+'BASH_SOURCE'
+     An array variable whose members are the source filenames where the
+     corresponding shell function names in the 'FUNCNAME' array variable
+     are defined.  The shell function '${FUNCNAME[$i]}' is defined in
+     the file '${BASH_SOURCE[$i]}' and called from
+     '${BASH_SOURCE[$i+1]}'
+
+'BASH_SUBSHELL'
+     Incremented by one within each subshell or subshell environment
+     when the shell begins executing in that environment.  The initial
+     value is 0.  If 'BASH_SUBSHELL' is unset, it loses its special
+     properties, even if it is subsequently reset.
+
+'BASH_VERSINFO'
+     A readonly array variable (*note Arrays::) whose members hold
+     version information for this instance of Bash.  The values assigned
+     to the array members are as follows:
+
+     'BASH_VERSINFO[0]'
+          The major version number (the "release").
+
+     'BASH_VERSINFO[1]'
+          The minor version number (the "version").
+
+     'BASH_VERSINFO[2]'
+          The patch level.
+
+     'BASH_VERSINFO[3]'
+          The build version.
+
+     'BASH_VERSINFO[4]'
+          The release status (e.g., 'beta1').
+
+     'BASH_VERSINFO[5]'
+          The value of 'MACHTYPE'.
+
+'BASH_VERSION'
+     The version number of the current instance of Bash.
+
+'BASH_XTRACEFD'
+     If set to an integer corresponding to a valid file descriptor, Bash
+     will write the trace output generated when 'set -x' is enabled to
+     that file descriptor.  This allows tracing output to be separated
+     from diagnostic and error messages.  The file descriptor is closed
+     when 'BASH_XTRACEFD' is unset or assigned a new value.  Unsetting
+     'BASH_XTRACEFD' or assigning it the empty string causes the trace
+     output to be sent to the standard error.  Note that setting
+     'BASH_XTRACEFD' to 2 (the standard error file descriptor) and then
+     unsetting it will result in the standard error being closed.
+
+'CHILD_MAX'
+     Set the number of exited child status values for the shell to
+     remember.  Bash will not allow this value to be decreased below a
+     POSIX-mandated minimum, and there is a maximum value (currently
+     8192) that this may not exceed.  The minimum value is
+     system-dependent.
+
+'COLUMNS'
+     Used by the 'select' command to determine the terminal width when
+     printing selection lists.  Automatically set if the 'checkwinsize'
+     option is enabled (*note The Shopt Builtin::), or in an interactive
+     shell upon receipt of a 'SIGWINCH'.
+
+'COMP_CWORD'
+     An index into '${COMP_WORDS}' of the word containing the current
+     cursor position.  This variable is available only in shell
+     functions invoked by the programmable completion facilities (*note
+     Programmable Completion::).
+
+'COMP_LINE'
+     The current command line.  This variable is available only in shell
+     functions and external commands invoked by the programmable
+     completion facilities (*note Programmable Completion::).
+
+'COMP_POINT'
+     The index of the current cursor position relative to the beginning
+     of the current command.  If the current cursor position is at the
+     end of the current command, the value of this variable is equal to
+     '${#COMP_LINE}'.  This variable is available only in shell
+     functions and external commands invoked by the programmable
+     completion facilities (*note Programmable Completion::).
+
+'COMP_TYPE'
+     Set to an integer value corresponding to the type of completion
+     attempted that caused a completion function to be called: <TAB>,
+     for normal completion, '?', for listing completions after
+     successive tabs, '!', for listing alternatives on partial word
+     completion, '@', to list completions if the word is not unmodified,
+     or '%', for menu completion.  This variable is available only in
+     shell functions and external commands invoked by the programmable
+     completion facilities (*note Programmable Completion::).
+
+'COMP_KEY'
+     The key (or final key of a key sequence) used to invoke the current
+     completion function.
+
+'COMP_WORDBREAKS'
+     The set of characters that the Readline library treats as word
+     separators when performing word completion.  If 'COMP_WORDBREAKS'
+     is unset, it loses its special properties, even if it is
+     subsequently reset.
+
+'COMP_WORDS'
+     An array variable consisting of the individual words in the current
+     command line.  The line is split into words as Readline would split
+     it, using 'COMP_WORDBREAKS' as described above.  This variable is
+     available only in shell functions invoked by the programmable
+     completion facilities (*note Programmable Completion::).
+
+'COMPREPLY'
+     An array variable from which Bash reads the possible completions
+     generated by a shell function invoked by the programmable
+     completion facility (*note Programmable Completion::).  Each array
+     element contains one possible completion.
+
+'COPROC'
+     An array variable created to hold the file descriptors for output
+     from and input to an unnamed coprocess (*note Coprocesses::).
+
+'DIRSTACK'
+     An array variable containing the current contents of the directory
+     stack.  Directories appear in the stack in the order they are
+     displayed by the 'dirs' builtin.  Assigning to members of this
+     array variable may be used to modify directories already in the
+     stack, but the 'pushd' and 'popd' builtins must be used to add and
+     remove directories.  Assignment to this variable will not change
+     the current directory.  If 'DIRSTACK' is unset, it loses its
+     special properties, even if it is subsequently reset.
+
+'EMACS'
+     If Bash finds this variable in the environment when the shell
+     starts with value 't', it assumes that the shell is running in an
+     Emacs shell buffer and disables line editing.
+
+'ENV'
+     Expanded and executed similarly to 'BASH_ENV' (*note Bash Startup
+     Files::) when an interactive shell is invoked in POSIX Mode (*note
+     Bash POSIX Mode::).
+
+'EPOCHREALTIME'
+     Each time this parameter is referenced, it expands to the number of
+     seconds since the Unix Epoch as a floating point value with
+     micro-second granularity (see the documentation for the C library
+     function 'time' for the definition of Epoch).  Assignments to
+     'EPOCHREALTIME' are ignored.  If 'EPOCHREALTIME' is unset, it loses
+     its special properties, even if it is subsequently reset.
+
+'EPOCHSECONDS'
+     Each time this parameter is referenced, it expands to the number of
+     seconds since the Unix Epoch (see the documentation for the C
+     library function 'time' for the definition of Epoch).  Assignments
+     to 'EPOCHSECONDS' are ignored.  If 'EPOCHSECONDS' is unset, it
+     loses its special properties, even if it is subsequently reset.
+
+'EUID'
+     The numeric effective user id of the current user.  This variable
+     is readonly.
+
+'EXECIGNORE'
+     A colon-separated list of shell patterns (*note Pattern Matching::)
+     defining the list of filenames to be ignored by command search
+     using 'PATH'.  Files whose full pathnames match one of these
+     patterns are not considered executable files for the purposes of
+     completion and command execution via 'PATH' lookup.  This does not
+     affect the behavior of the '[', 'test', and '[[' commands.  Full
+     pathnames in the command hash table are not subject to
+     'EXECIGNORE'.  Use this variable to ignore shared library files
+     that have the executable bit set, but are not executable files.
+     The pattern matching honors the setting of the 'extglob' shell
+     option.
+
+'FCEDIT'
+     The editor used as a default by the '-e' option to the 'fc' builtin
+     command.
+
+'FIGNORE'
+     A colon-separated list of suffixes to ignore when performing
+     filename completion.  A filename whose suffix matches one of the
+     entries in 'FIGNORE' is excluded from the list of matched
+     filenames.  A sample value is '.o:~'
+
+'FUNCNAME'
+     An array variable containing the names of all shell functions
+     currently in the execution call stack.  The element with index 0 is
+     the name of any currently-executing shell function.  The
+     bottom-most element (the one with the highest index) is '"main"'.
+     This variable exists only when a shell function is executing.
+     Assignments to 'FUNCNAME' have no effect.  If 'FUNCNAME' is unset,
+     it loses its special properties, even if it is subsequently reset.
+
+     This variable can be used with 'BASH_LINENO' and 'BASH_SOURCE'.
+     Each element of 'FUNCNAME' has corresponding elements in
+     'BASH_LINENO' and 'BASH_SOURCE' to describe the call stack.  For
+     instance, '${FUNCNAME[$i]}' was called from the file
+     '${BASH_SOURCE[$i+1]}' at line number '${BASH_LINENO[$i]}'.  The
+     'caller' builtin displays the current call stack using this
+     information.
+
+'FUNCNEST'
+     If set to a numeric value greater than 0, defines a maximum
+     function nesting level.  Function invocations that exceed this
+     nesting level will cause the current command to abort.
+
+'GLOBIGNORE'
+     A colon-separated list of patterns defining the set of file names
+     to be ignored by filename expansion.  If a file name matched by a
+     filename expansion pattern also matches one of the patterns in
+     'GLOBIGNORE', it is removed from the list of matches.  The pattern
+     matching honors the setting of the 'extglob' shell option.
+
+'GROUPS'
+     An array variable containing the list of groups of which the
+     current user is a member.  Assignments to 'GROUPS' have no effect.
+     If 'GROUPS' is unset, it loses its special properties, even if it
+     is subsequently reset.
+
+'histchars'
+     Up to three characters which control history expansion, quick
+     substitution, and tokenization (*note History Interaction::).  The
+     first character is the "history expansion" character, that is, the
+     character which signifies the start of a history expansion,
+     normally '!'.  The second character is the character which
+     signifies 'quick substitution' when seen as the first character on
+     a line, normally '^'.  The optional third character is the
+     character which indicates that the remainder of the line is a
+     comment when found as the first character of a word, usually '#'.
+     The history comment character causes history substitution to be
+     skipped for the remaining words on the line.  It does not
+     necessarily cause the shell parser to treat the rest of the line as
+     a comment.
+
+'HISTCMD'
+     The history number, or index in the history list, of the current
+     command.  Assignments to 'HISTCMD' are ignored.  If 'HISTCMD' is
+     unset, it loses its special properties, even if it is subsequently
+     reset.
+
+'HISTCONTROL'
+     A colon-separated list of values controlling how commands are saved
+     on the history list.  If the list of values includes 'ignorespace',
+     lines which begin with a space character are not saved in the
+     history list.  A value of 'ignoredups' causes lines which match the
+     previous history entry to not be saved.  A value of 'ignoreboth' is
+     shorthand for 'ignorespace' and 'ignoredups'.  A value of
+     'erasedups' causes all previous lines matching the current line to
+     be removed from the history list before that line is saved.  Any
+     value not in the above list is ignored.  If 'HISTCONTROL' is unset,
+     or does not include a valid value, all lines read by the shell
+     parser are saved on the history list, subject to the value of
+     'HISTIGNORE'.  The second and subsequent lines of a multi-line
+     compound command are not tested, and are added to the history
+     regardless of the value of 'HISTCONTROL'.
+
+'HISTFILE'
+     The name of the file to which the command history is saved.  The
+     default value is '~/.bash_history'.
+
+'HISTFILESIZE'
+     The maximum number of lines contained in the history file.  When
+     this variable is assigned a value, the history file is truncated,
+     if necessary, to contain no more than that number of lines by
+     removing the oldest entries.  The history file is also truncated to
+     this size after writing it when a shell exits.  If the value is 0,
+     the history file is truncated to zero size.  Non-numeric values and
+     numeric values less than zero inhibit truncation.  The shell sets
+     the default value to the value of 'HISTSIZE' after reading any
+     startup files.
+
+'HISTIGNORE'
+     A colon-separated list of patterns used to decide which command
+     lines should be saved on the history list.  Each pattern is
+     anchored at the beginning of the line and must match the complete
+     line (no implicit '*' is appended).  Each pattern is tested against
+     the line after the checks specified by 'HISTCONTROL' are applied.
+     In addition to the normal shell pattern matching characters, '&'
+     matches the previous history line.  '&' may be escaped using a
+     backslash; the backslash is removed before attempting a match.  The
+     second and subsequent lines of a multi-line compound command are
+     not tested, and are added to the history regardless of the value of
+     'HISTIGNORE'.  The pattern matching honors the setting of the
+     'extglob' shell option.
+
+     'HISTIGNORE' subsumes the function of 'HISTCONTROL'.  A pattern of
+     '&' is identical to 'ignoredups', and a pattern of '[ ]*' is
+     identical to 'ignorespace'.  Combining these two patterns,
+     separating them with a colon, provides the functionality of
+     'ignoreboth'.
+
+'HISTSIZE'
+     The maximum number of commands to remember on the history list.  If
+     the value is 0, commands are not saved in the history list.
+     Numeric values less than zero result in every command being saved
+     on the history list (there is no limit).  The shell sets the
+     default value to 500 after reading any startup files.
+
+'HISTTIMEFORMAT'
+     If this variable is set and not null, its value is used as a format
+     string for 'strftime' to print the time stamp associated with each
+     history entry displayed by the 'history' builtin.  If this variable
+     is set, time stamps are written to the history file so they may be
+     preserved across shell sessions.  This uses the history comment
+     character to distinguish timestamps from other history lines.
+
+'HOSTFILE'
+     Contains the name of a file in the same format as '/etc/hosts' that
+     should be read when the shell needs to complete a hostname.  The
+     list of possible hostname completions may be changed while the
+     shell is running; the next time hostname completion is attempted
+     after the value is changed, Bash adds the contents of the new file
+     to the existing list.  If 'HOSTFILE' is set, but has no value, or
+     does not name a readable file, Bash attempts to read '/etc/hosts'
+     to obtain the list of possible hostname completions.  When
+     'HOSTFILE' is unset, the hostname list is cleared.
+
+'HOSTNAME'
+     The name of the current host.
+
+'HOSTTYPE'
+     A string describing the machine Bash is running on.
+
+'IGNOREEOF'
+     Controls the action of the shell on receipt of an 'EOF' character
+     as the sole input.  If set, the value denotes the number of
+     consecutive 'EOF' characters that can be read as the first
+     character on an input line before the shell will exit.  If the
+     variable exists but does not have a numeric value, or has no value,
+     then the default is 10.  If the variable does not exist, then 'EOF'
+     signifies the end of input to the shell.  This is only in effect
+     for interactive shells.
+
+'INPUTRC'
+     The name of the Readline initialization file, overriding the
+     default of '~/.inputrc'.
+
+'INSIDE_EMACS'
+     If Bash finds this variable in the environment when the shell
+     starts, it assumes that the shell is running in an Emacs shell
+     buffer and may disable line editing depending on the value of
+     'TERM'.
+
+'LANG'
+     Used to determine the locale category for any category not
+     specifically selected with a variable starting with 'LC_'.
+
+'LC_ALL'
+     This variable overrides the value of 'LANG' and any other 'LC_'
+     variable specifying a locale category.
+
+'LC_COLLATE'
+     This variable determines the collation order used when sorting the
+     results of filename expansion, and determines the behavior of range
+     expressions, equivalence classes, and collating sequences within
+     filename expansion and pattern matching (*note Filename
+     Expansion::).
+
+'LC_CTYPE'
+     This variable determines the interpretation of characters and the
+     behavior of character classes within filename expansion and pattern
+     matching (*note Filename Expansion::).
+
+'LC_MESSAGES'
+     This variable determines the locale used to translate double-quoted
+     strings preceded by a '$' (*note Locale Translation::).
+
+'LC_NUMERIC'
+     This variable determines the locale category used for number
+     formatting.
+
+'LC_TIME'
+     This variable determines the locale category used for data and time
+     formatting.
+
+'LINENO'
+     The line number in the script or shell function currently
+     executing.  If 'LINENO' is unset, it loses its special properties,
+     even if it is subsequently reset.
+
+'LINES'
+     Used by the 'select' command to determine the column length for
+     printing selection lists.  Automatically set if the 'checkwinsize'
+     option is enabled (*note The Shopt Builtin::), or in an interactive
+     shell upon receipt of a 'SIGWINCH'.
+
+'MACHTYPE'
+     A string that fully describes the system type on which Bash is
+     executing, in the standard GNU CPU-COMPANY-SYSTEM format.
+
+'MAILCHECK'
+     How often (in seconds) that the shell should check for mail in the
+     files specified in the 'MAILPATH' or 'MAIL' variables.  The default
+     is 60 seconds.  When it is time to check for mail, the shell does
+     so before displaying the primary prompt.  If this variable is
+     unset, or set to a value that is not a number greater than or equal
+     to zero, the shell disables mail checking.
+
+'MAPFILE'
+     An array variable created to hold the text read by the 'mapfile'
+     builtin when no variable name is supplied.
+
+'OLDPWD'
+     The previous working directory as set by the 'cd' builtin.
+
+'OPTERR'
+     If set to the value 1, Bash displays error messages generated by
+     the 'getopts' builtin command.
+
+'OSTYPE'
+     A string describing the operating system Bash is running on.
+
+'PIPESTATUS'
+     An array variable (*note Arrays::) containing a list of exit status
+     values from the processes in the most-recently-executed foreground
+     pipeline (which may contain only a single command).
+
+'POSIXLY_CORRECT'
+     If this variable is in the environment when Bash starts, the shell
+     enters POSIX mode (*note Bash POSIX Mode::) before reading the
+     startup files, as if the '--posix' invocation option had been
+     supplied.  If it is set while the shell is running, Bash enables
+     POSIX mode, as if the command
+          set -o posix
+     had been executed.  When the shell enters POSIX mode, it sets this
+     variable if it was not already set.
+
+'PPID'
+     The process ID of the shell's parent process.  This variable is
+     readonly.
+
+'PROMPT_COMMAND'
+     If this variable is set, and is an array, the value of each set
+     element is interpreted as a command to execute before printing the
+     primary prompt ('$PS1').  If this is set but not an array variable,
+     its value is used as a command to execute instead.
+
+'PROMPT_DIRTRIM'
+     If set to a number greater than zero, the value is used as the
+     number of trailing directory components to retain when expanding
+     the '\w' and '\W' prompt string escapes (*note Controlling the
+     Prompt::).  Characters removed are replaced with an ellipsis.
+
+'PS0'
+     The value of this parameter is expanded like 'PS1' and displayed by
+     interactive shells after reading a command and before the command
+     is executed.
+
+'PS3'
+     The value of this variable is used as the prompt for the 'select'
+     command.  If this variable is not set, the 'select' command prompts
+     with '#? '
+
+'PS4'
+     The value of this parameter is expanded like 'PS1' and the expanded
+     value is the prompt printed before the command line is echoed when
+     the '-x' option is set (*note The Set Builtin::).  The first
+     character of the expanded value is replicated multiple times, as
+     necessary, to indicate multiple levels of indirection.  The default
+     is '+ '.
+
+'PWD'
+     The current working directory as set by the 'cd' builtin.
+
+'RANDOM'
+     Each time this parameter is referenced, it expands to a random
+     integer between 0 and 32767.  Assigning a value to this variable
+     seeds the random number generator.  If 'RANDOM' is unset, it loses
+     its special properties, even if it is subsequently reset.
+
+'READLINE_ARGUMENT'
+     Any numeric argument given to a Readline command that was defined
+     using 'bind -x' (*note Bash Builtins:: when it was invoked.
+
+'READLINE_LINE'
+     The contents of the Readline line buffer, for use with 'bind -x'
+     (*note Bash Builtins::).
+
+'READLINE_MARK'
+     The position of the "mark" (saved insertion point) in the Readline
+     line buffer, for use with 'bind -x' (*note Bash Builtins::).  The
+     characters between the insertion point and the mark are often
+     called the "region".
+
+'READLINE_POINT'
+     The position of the insertion point in the Readline line buffer,
+     for use with 'bind -x' (*note Bash Builtins::).
+
+'REPLY'
+     The default variable for the 'read' builtin.
+
+'SECONDS'
+     This variable expands to the number of seconds since the shell was
+     started.  Assignment to this variable resets the count to the value
+     assigned, and the expanded value becomes the value assigned plus
+     the number of seconds since the assignment.  The number of seconds
+     at shell invocation and the current time are always determined by
+     querying the system clock.  If 'SECONDS' is unset, it loses its
+     special properties, even if it is subsequently reset.
+
+'SHELL'
+     This environment variable expands to the full pathname to the
+     shell.  If it is not set when the shell starts, Bash assigns to it
+     the full pathname of the current user's login shell.
+
+'SHELLOPTS'
+     A colon-separated list of enabled shell options.  Each word in the
+     list is a valid argument for the '-o' option to the 'set' builtin
+     command (*note The Set Builtin::).  The options appearing in
+     'SHELLOPTS' are those reported as 'on' by 'set -o'.  If this
+     variable is in the environment when Bash starts up, each shell
+     option in the list will be enabled before reading any startup
+     files.  This variable is readonly.
+
+'SHLVL'
+     Incremented by one each time a new instance of Bash is started.
+     This is intended to be a count of how deeply your Bash shells are
+     nested.
+
+'SRANDOM'
+     This variable expands to a 32-bit pseudo-random number each time it
+     is referenced.  The random number generator is not linear on
+     systems that support '/dev/urandom' or 'arc4random', so each
+     returned number has no relationship to the numbers preceding it.
+     The random number generator cannot be seeded, so assignments to
+     this variable have no effect.  If 'SRANDOM' is unset, it loses its
+     special properties, even if it is subsequently reset.
+
+'TIMEFORMAT'
+     The value of this parameter is used as a format string specifying
+     how the timing information for pipelines prefixed with the 'time'
+     reserved word should be displayed.  The '%' character introduces an
+     escape sequence that is expanded to a time value or other
+     information.  The escape sequences and their meanings are as
+     follows; the braces denote optional portions.
+
+     '%%'
+          A literal '%'.
+
+     '%[P][l]R'
+          The elapsed time in seconds.
+
+     '%[P][l]U'
+          The number of CPU seconds spent in user mode.
+
+     '%[P][l]S'
+          The number of CPU seconds spent in system mode.
+
+     '%P'
+          The CPU percentage, computed as (%U + %S) / %R.
+
+     The optional P is a digit specifying the precision, the number of
+     fractional digits after a decimal point.  A value of 0 causes no
+     decimal point or fraction to be output.  At most three places after
+     the decimal point may be specified; values of P greater than 3 are
+     changed to 3.  If P is not specified, the value 3 is used.
+
+     The optional 'l' specifies a longer format, including minutes, of
+     the form MMmSS.FFs.  The value of P determines whether or not the
+     fraction is included.
+
+     If this variable is not set, Bash acts as if it had the value
+          $'\nreal\t%3lR\nuser\t%3lU\nsys\t%3lS'
+     If the value is null, no timing information is displayed.  A
+     trailing newline is added when the format string is displayed.
+
+'TMOUT'
+     If set to a value greater than zero, 'TMOUT' is treated as the
+     default timeout for the 'read' builtin (*note Bash Builtins::).
+     The 'select' command (*note Conditional Constructs::) terminates if
+     input does not arrive after 'TMOUT' seconds when input is coming
+     from a terminal.
+
+     In an interactive shell, the value is interpreted as the number of
+     seconds to wait for a line of input after issuing the primary
+     prompt.  Bash terminates after waiting for that number of seconds
+     if a complete line of input does not arrive.
+
+'TMPDIR'
+     If set, Bash uses its value as the name of a directory in which
+     Bash creates temporary files for the shell's use.
+
+'UID'
+     The numeric real user id of the current user.  This variable is
+     readonly.

+
+6.1 Invoking Bash
+=================
+
+     bash [long-opt] [-ir] [-abefhkmnptuvxdBCDHP] [-o OPTION]
+         [-O SHOPT_OPTION] [ARGUMENT ...]
+     bash [long-opt] [-abefhkmnptuvxdBCDHP] [-o OPTION]
+         [-O SHOPT_OPTION] -c STRING [ARGUMENT ...]
+     bash [long-opt] -s [-abefhkmnptuvxdBCDHP] [-o OPTION]
+         [-O SHOPT_OPTION] [ARGUMENT ...]
+
+   All of the single-character options used with the 'set' builtin
+(*note The Set Builtin::) can be used as options when the shell is
+invoked.  In addition, there are several multi-character options that
+you can use.  These options must appear on the command line before the
+single-character options to be recognized.
+
+'--debugger'
+     Arrange for the debugger profile to be executed before the shell
+     starts.  Turns on extended debugging mode (see *note The Shopt
+     Builtin:: for a description of the 'extdebug' option to the 'shopt'
+     builtin).
+
+'--dump-po-strings'
+     A list of all double-quoted strings preceded by '$' is printed on
+     the standard output in the GNU 'gettext' PO (portable object) file
+     format.  Equivalent to '-D' except for the output format.
+
+'--dump-strings'
+     Equivalent to '-D'.
+
+'--help'
+     Display a usage message on standard output and exit successfully.
+
+'--init-file FILENAME'
+'--rcfile FILENAME'
+     Execute commands from FILENAME (instead of '~/.bashrc') in an
+     interactive shell.
+
+'--login'
+     Equivalent to '-l'.
+
+'--noediting'
+     Do not use the GNU Readline library (*note Command Line Editing::)
+     to read command lines when the shell is interactive.
+
+'--noprofile'
+     Don't load the system-wide startup file '/etc/profile' or any of
+     the personal initialization files '~/.bash_profile',
+     '~/.bash_login', or '~/.profile' when Bash is invoked as a login
+     shell.
+
+'--norc'
+     Don't read the '~/.bashrc' initialization file in an interactive
+     shell.  This is on by default if the shell is invoked as 'sh'.
+
+'--posix'
+     Change the behavior of Bash where the default operation differs
+     from the POSIX standard to match the standard.  This is intended to
+     make Bash behave as a strict superset of that standard.  *Note Bash
+     POSIX Mode::, for a description of the Bash POSIX mode.
+
+'--restricted'
+     Make the shell a restricted shell (*note The Restricted Shell::).
+
+'--verbose'
+     Equivalent to '-v'.  Print shell input lines as they're read.
+
+'--version'
+     Show version information for this instance of Bash on the standard
+     output and exit successfully.
+
+   There are several single-character options that may be supplied at
+invocation which are not available with the 'set' builtin.
+
+'-c'
+     Read and execute commands from the first non-option argument
+     COMMAND_STRING, then exit.  If there are arguments after the
+     COMMAND_STRING, the first argument is assigned to '$0' and any
+     remaining arguments are assigned to the positional parameters.  The
+     assignment to '$0' sets the name of the shell, which is used in
+     warning and error messages.
+
+'-i'
+     Force the shell to run interactively.  Interactive shells are
+     described in *note Interactive Shells::.
+
+'-l'
+     Make this shell act as if it had been directly invoked by login.
+     When the shell is interactive, this is equivalent to starting a
+     login shell with 'exec -l bash'.  When the shell is not
+     interactive, the login shell startup files will be executed.  'exec
+     bash -l' or 'exec bash --login' will replace the current shell with
+     a Bash login shell.  *Note Bash Startup Files::, for a description
+     of the special behavior of a login shell.
+
+'-r'
+     Make the shell a restricted shell (*note The Restricted Shell::).
+
+'-s'
+     If this option is present, or if no arguments remain after option
+     processing, then commands are read from the standard input.  This
+     option allows the positional parameters to be set when invoking an
+     interactive shell or when reading input through a pipe.
+
+'-D'
+     A list of all double-quoted strings preceded by '$' is printed on
+     the standard output.  These are the strings that are subject to
+     language translation when the current locale is not 'C' or 'POSIX'
+     (*note Locale Translation::).  This implies the '-n' option; no
+     commands will be executed.
+
+'[-+]O [SHOPT_OPTION]'
+     SHOPT_OPTION is one of the shell options accepted by the 'shopt'
+     builtin (*note The Shopt Builtin::).  If SHOPT_OPTION is present,
+     '-O' sets the value of that option; '+O' unsets it.  If
+     SHOPT_OPTION is not supplied, the names and values of the shell
+     options accepted by 'shopt' are printed on the standard output.  If
+     the invocation option is '+O', the output is displayed in a format
+     that may be reused as input.
+
+'--'
+     A '--' signals the end of options and disables further option
+     processing.  Any arguments after the '--' are treated as filenames
+     and arguments.
+
+   A _login_ shell is one whose first character of argument zero is '-',
+or one invoked with the '--login' option.
+
+   An _interactive_ shell is one started without non-option arguments,
+unless '-s' is specified, without specifying the '-c' option, and whose
+input and output are both connected to terminals (as determined by
+'isatty(3)'), or one started with the '-i' option.  *Note Interactive
+Shells::, for more information.
+
+   If arguments remain after option processing, and neither the '-c' nor
+the '-s' option has been supplied, the first argument is assumed to be
+the name of a file containing shell commands (*note Shell Scripts::).
+When Bash is invoked in this fashion, '$0' is set to the name of the
+file, and the positional parameters are set to the remaining arguments.
+Bash reads and executes commands from this file, then exits.  Bash's
+exit status is the exit status of the last command executed in the
+script.  If no commands are executed, the exit status is 0.

+6.2 Bash Startup Files
+======================
+
+This section describes how Bash executes its startup files.  If any of
+the files exist but cannot be read, Bash reports an error.  Tildes are
+expanded in filenames as described above under Tilde Expansion (*note
+Tilde Expansion::).
+
+   Interactive shells are described in *note Interactive Shells::.
+
+Invoked as an interactive login shell, or with '--login'
+........................................................
+
+When Bash is invoked as an interactive login shell, or as a
+non-interactive shell with the '--login' option, it first reads and
+executes commands from the file '/etc/profile', if that file exists.
+After reading that file, it looks for '~/.bash_profile',
+'~/.bash_login', and '~/.profile', in that order, and reads and executes
+commands from the first one that exists and is readable.  The
+'--noprofile' option may be used when the shell is started to inhibit
+this behavior.
+
+   When an interactive login shell exits, or a non-interactive login
+shell executes the 'exit' builtin command, Bash reads and executes
+commands from the file '~/.bash_logout', if it exists.
+
+Invoked as an interactive non-login shell
+.........................................
+
+When an interactive shell that is not a login shell is started, Bash
+reads and executes commands from '~/.bashrc', if that file exists.  This
+may be inhibited by using the '--norc' option.  The '--rcfile FILE'
+option will force Bash to read and execute commands from FILE instead of
+'~/.bashrc'.
+
+   So, typically, your '~/.bash_profile' contains the line
+     if [ -f ~/.bashrc ]; then . ~/.bashrc; fi
+after (or before) any login-specific initializations.
+
+Invoked non-interactively
+.........................
+
+When Bash is started non-interactively, to run a shell script, for
+example, it looks for the variable 'BASH_ENV' in the environment,
+expands its value if it appears there, and uses the expanded value as
+the name of a file to read and execute.  Bash behaves as if the
+following command were executed:
+     if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi
+but the value of the 'PATH' variable is not used to search for the
+filename.
+
+   As noted above, if a non-interactive shell is invoked with the
+'--login' option, Bash attempts to read and execute commands from the
+login shell startup files.
+
+Invoked with name 'sh'
+......................
+
+If Bash is invoked with the name 'sh', it tries to mimic the startup
+behavior of historical versions of 'sh' as closely as possible, while
+conforming to the POSIX standard as well.
+
+   When invoked as an interactive login shell, or as a non-interactive
+shell with the '--login' option, it first attempts to read and execute
+commands from '/etc/profile' and '~/.profile', in that order.  The
+'--noprofile' option may be used to inhibit this behavior.  When invoked
+as an interactive shell with the name 'sh', Bash looks for the variable
+'ENV', expands its value if it is defined, and uses the expanded value
+as the name of a file to read and execute.  Since a shell invoked as
+'sh' does not attempt to read and execute commands from any other
+startup files, the '--rcfile' option has no effect.  A non-interactive
+shell invoked with the name 'sh' does not attempt to read any other
+startup files.
+
+   When invoked as 'sh', Bash enters POSIX mode after the startup files
+are read.
+
+Invoked in POSIX mode
+.....................
+
+When Bash is started in POSIX mode, as with the '--posix' command line
+option, it follows the POSIX standard for startup files.  In this mode,
+interactive shells expand the 'ENV' variable and commands are read and
+executed from the file whose name is the expanded value.  No other
+startup files are read.
+
+Invoked by remote shell daemon
+..............................
+
+Bash attempts to determine when it is being run with its standard input
+connected to a network connection, as when executed by the historical
+remote shell daemon, usually 'rshd', or the secure shell daemon 'sshd'.
+If Bash determines it is being run non-interactively in this fashion, it
+reads and executes commands from '~/.bashrc', if that file exists and is
+readable.  It will not do this if invoked as 'sh'.  The '--norc' option
+may be used to inhibit this behavior, and the '--rcfile' option may be
+used to force another file to be read, but neither 'rshd' nor 'sshd'
+generally invoke the shell with those options or allow them to be
+specified.
+
+Invoked with unequal effective and real UID/GIDs
+................................................
+
+If Bash is started with the effective user (group) id not equal to the
+real user (group) id, and the '-p' option is not supplied, no startup
+files are read, shell functions are not inherited from the environment,
+the 'SHELLOPTS', 'BASHOPTS', 'CDPATH', and 'GLOBIGNORE' variables, if
+they appear in the environment, are ignored, and the effective user id
+is set to the real user id.  If the '-p' option is supplied at
+invocation, the startup behavior is the same, but the effective user id
+is not reset.

+
+6.3.1 What is an Interactive Shell?
+-----------------------------------
+
+An interactive shell is one started without non-option arguments (unless
+'-s' is specified) and without specifying the '-c' option, whose input
+and error output are both connected to terminals (as determined by
+'isatty(3)'), or one started with the '-i' option.
+
+   An interactive shell generally reads from and writes to a user's
+terminal.
+
+   The '-s' invocation option may be used to set the positional
+parameters when an interactive shell is started.
+
+
+File: bashref.info,  Node: Is this Shell Interactive?,  Next: Interactive Shell Behavior,  Prev: What is an Interactive Shell?,  Up: Interactive Shells
+
+6.3.2 Is this Shell Interactive?
+--------------------------------
+
+To determine within a startup script whether or not Bash is running
+interactively, test the value of the '-' special parameter.  It contains
+'i' when the shell is interactive.  For example:
+
+     case "$-" in
+     *i*)	echo This shell is interactive ;;
+     *)	echo This shell is not interactive ;;
+     esac
+
+   Alternatively, startup scripts may examine the variable 'PS1'; it is
+unset in non-interactive shells, and set in interactive shells.  Thus:
+
+     if [ -z "$PS1" ]; then
+             echo This shell is not interactive
+     else
+             echo This shell is interactive
+     fi
+
+
+File: bashref.info,  Node: Interactive Shell Behavior,  Prev: Is this Shell Interactive?,  Up: Interactive Shells
+
+6.3.3 Interactive Shell Behavior
+--------------------------------
+
+When the shell is running interactively, it changes its behavior in
+several ways.
+
+  1. Startup files are read and executed as described in *note Bash
+     Startup Files::.
+
+  2. Job Control (*note Job Control::) is enabled by default.  When job
+     control is in effect, Bash ignores the keyboard-generated job
+     control signals 'SIGTTIN', 'SIGTTOU', and 'SIGTSTP'.
+
+  3. Bash expands and displays 'PS1' before reading the first line of a
+     command, and expands and displays 'PS2' before reading the second
+     and subsequent lines of a multi-line command.  Bash expands and
+     displays 'PS0' after it reads a command but before executing it.
+     See *note Controlling the Prompt::, for a complete list of prompt
+     string escape sequences.
+
+  4. Bash executes the values of the set elements of the
+     'PROMPT_COMMAND' array variable as commands before printing the
+     primary prompt, '$PS1' (*note Bash Variables::).
+
+  5. Readline (*note Command Line Editing::) is used to read commands
+     from the user's terminal.
+
+  6. Bash inspects the value of the 'ignoreeof' option to 'set -o'
+     instead of exiting immediately when it receives an 'EOF' on its
+     standard input when reading a command (*note The Set Builtin::).
+
+  7. Command history (*note Bash History Facilities::) and history
+     expansion (*note History Interaction::) are enabled by default.
+     Bash will save the command history to the file named by '$HISTFILE'
+     when a shell with history enabled exits.
+
+  8. Alias expansion (*note Aliases::) is performed by default.
+
+  9. In the absence of any traps, Bash ignores 'SIGTERM' (*note
+     Signals::).
+
+  10. In the absence of any traps, 'SIGINT' is caught and handled (*note
+     Signals::).  'SIGINT' will interrupt some shell builtins.
+
+  11. An interactive login shell sends a 'SIGHUP' to all jobs on exit if
+     the 'huponexit' shell option has been enabled (*note Signals::).
+
+  12. The '-n' invocation option is ignored, and 'set -n' has no effect
+     (*note The Set Builtin::).
+
+  13. Bash will check for mail periodically, depending on the values of
+     the 'MAIL', 'MAILPATH', and 'MAILCHECK' shell variables (*note Bash
+     Variables::).
+
+  14. Expansion errors due to references to unbound shell variables
+     after 'set -u' has been enabled will not cause the shell to exit
+     (*note The Set Builtin::).
+
+  15. The shell will not exit on expansion errors caused by VAR being
+     unset or null in '${VAR:?WORD}' expansions (*note Shell Parameter
+     Expansion::).
+
+  16. Redirection errors encountered by shell builtins will not cause
+     the shell to exit.
+
+  17. When running in POSIX mode, a special builtin returning an error
+     status will not cause the shell to exit (*note Bash POSIX Mode::).
+
+  18. A failed 'exec' will not cause the shell to exit (*note Bourne
+     Shell Builtins::).
+
+  19. Parser syntax errors will not cause the shell to exit.
+
+  20. If the 'cdspell' shell option is enabled, the shell will attempt
+     simple spelling correction for directory arguments to the 'cd'
+     builtin (see the description of the 'cdspell' option to the 'shopt'
+     builtin in *note The Shopt Builtin::).  The 'cdspell' option is
+     only effective in interactive shells.
+
+  21. The shell will check the value of the 'TMOUT' variable and exit if
+     a command is not read within the specified number of seconds after
+     printing '$PS1' (*note Bash Variables::).
+

+
+6.4 Bash Conditional Expressions
+================================
+
+Conditional expressions are used by the '[[' compound command (*note
+Conditional Constructs::) and the 'test' and '[' builtin commands (*note
+Bourne Shell Builtins::).  The 'test' and '[' commands determine their
+behavior based on the number of arguments; see the descriptions of those
+commands for any other command-specific actions.
+
+   Expressions may be unary or binary, and are formed from the following
+primaries.  Unary expressions are often used to examine the status of a
+file.  There are string operators and numeric comparison operators as
+well.  Bash handles several filenames specially when they are used in
+expressions.  If the operating system on which Bash is running provides
+these special files, Bash will use them; otherwise it will emulate them
+internally with this behavior: If the FILE argument to one of the
+primaries is of the form '/dev/fd/N', then file descriptor N is checked.
+If the FILE argument to one of the primaries is one of '/dev/stdin',
+'/dev/stdout', or '/dev/stderr', file descriptor 0, 1, or 2,
+respectively, is checked.
+
+   When used with '[[', the '<' and '>' operators sort lexicographically
+using the current locale.  The 'test' command uses ASCII ordering.
+
+   Unless otherwise specified, primaries that operate on files follow
+symbolic links and operate on the target of the link, rather than the
+link itself.
+
+'-a FILE'
+     True if FILE exists.
+
+'-b FILE'
+     True if FILE exists and is a block special file.
+
+'-c FILE'
+     True if FILE exists and is a character special file.
+
+'-d FILE'
+     True if FILE exists and is a directory.
+
+'-e FILE'
+     True if FILE exists.
+
+'-f FILE'
+     True if FILE exists and is a regular file.
+
+'-g FILE'
+     True if FILE exists and its set-group-id bit is set.
+
+'-h FILE'
+     True if FILE exists and is a symbolic link.
+
+'-k FILE'
+     True if FILE exists and its "sticky" bit is set.
+
+'-p FILE'
+     True if FILE exists and is a named pipe (FIFO).
+
+'-r FILE'
+     True if FILE exists and is readable.
+
+'-s FILE'
+     True if FILE exists and has a size greater than zero.
+
+'-t FD'
+     True if file descriptor FD is open and refers to a terminal.
+
+'-u FILE'
+     True if FILE exists and its set-user-id bit is set.
+
+'-w FILE'
+     True if FILE exists and is writable.
+
+'-x FILE'
+     True if FILE exists and is executable.
+
+'-G FILE'
+     True if FILE exists and is owned by the effective group id.
+
+'-L FILE'
+     True if FILE exists and is a symbolic link.
+
+'-N FILE'
+     True if FILE exists and has been modified since it was last read.
+
+'-O FILE'
+     True if FILE exists and is owned by the effective user id.
+
+'-S FILE'
+     True if FILE exists and is a socket.
+
+'FILE1 -ef FILE2'
+     True if FILE1 and FILE2 refer to the same device and inode numbers.
+
+'FILE1 -nt FILE2'
+     True if FILE1 is newer (according to modification date) than FILE2,
+     or if FILE1 exists and FILE2 does not.
+
+'FILE1 -ot FILE2'
+     True if FILE1 is older than FILE2, or if FILE2 exists and FILE1
+     does not.
+
+'-o OPTNAME'
+     True if the shell option OPTNAME is enabled.  The list of options
+     appears in the description of the '-o' option to the 'set' builtin
+     (*note The Set Builtin::).
+
+'-v VARNAME'
+     True if the shell variable VARNAME is set (has been assigned a
+     value).
+
+'-R VARNAME'
+     True if the shell variable VARNAME is set and is a name reference.
+
+'-z STRING'
+     True if the length of STRING is zero.
+
+'-n STRING'
+'STRING'
+     True if the length of STRING is non-zero.
+
+'STRING1 == STRING2'
+'STRING1 = STRING2'
+     True if the strings are equal.  When used with the '[[' command,
+     this performs pattern matching as described above (*note
+     Conditional Constructs::).
+
+     '=' should be used with the 'test' command for POSIX conformance.
+
+'STRING1 != STRING2'
+     True if the strings are not equal.
+
+'STRING1 < STRING2'
+     True if STRING1 sorts before STRING2 lexicographically.
+
+'STRING1 > STRING2'
+     True if STRING1 sorts after STRING2 lexicographically.
+
+'ARG1 OP ARG2'
+     'OP' is one of '-eq', '-ne', '-lt', '-le', '-gt', or '-ge'.  These
+     arithmetic binary operators return true if ARG1 is equal to, not
+     equal to, less than, less than or equal to, greater than, or
+     greater than or equal to ARG2, respectively.  ARG1 and ARG2 may be
+     positive or negative integers.  When used with the '[[' command,
+     ARG1 and ARG2 are evaluated as arithmetic expressions (*note Shell
+     Arithmetic::).
+
+
+File: bashref.info,  Node: Shell Arithmetic,  Next: Aliases,  Prev: Bash Conditional Expressions,  Up: Bash Features
+
+6.5 Shell Arithmetic
+====================
+
+The shell allows arithmetic expressions to be evaluated, as one of the
+shell expansions or by using the '((' compound command, the 'let'
+builtin, or the '-i' option to the 'declare' builtin.
+
+   Evaluation is done in fixed-width integers with no check for
+overflow, though division by 0 is trapped and flagged as an error.  The
+operators and their precedence, associativity, and values are the same
+as in the C language.  The following list of operators is grouped into
+levels of equal-precedence operators.  The levels are listed in order of
+decreasing precedence.
+
+'ID++ ID--'
+     variable post-increment and post-decrement
+
+'++ID --ID'
+     variable pre-increment and pre-decrement
+
+'- +'
+     unary minus and plus
+
+'! ~'
+     logical and bitwise negation
+
+'**'
+     exponentiation
+
+'* / %'
+     multiplication, division, remainder
+
+'+ -'
+     addition, subtraction
+
+'<< >>'
+     left and right bitwise shifts
+
+'<= >= < >'
+     comparison
+
+'== !='
+     equality and inequality
+
+'&'
+     bitwise AND
+
+'^'
+     bitwise exclusive OR
+
+'|'
+     bitwise OR
+
+'&&'
+     logical AND
+
+'||'
+     logical OR
+
+'expr ? expr : expr'
+     conditional operator
+
+'= *= /= %= += -= <<= >>= &= ^= |='
+     assignment
+
+'expr1 , expr2'
+     comma
+
+   Shell variables are allowed as operands; parameter expansion is
+performed before the expression is evaluated.  Within an expression,
+shell variables may also be referenced by name without using the
+parameter expansion syntax.  A shell variable that is null or unset
+evaluates to 0 when referenced by name without using the parameter
+expansion syntax.  The value of a variable is evaluated as an arithmetic
+expression when it is referenced, or when a variable which has been
+given the 'integer' attribute using 'declare -i' is assigned a value.  A
+null value evaluates to 0.  A shell variable need not have its 'integer'
+attribute turned on to be used in an expression.
+
+   Integer constants follow the C language definition, without suffixes
+or character constants.  Constants with a leading 0 are interpreted as
+octal numbers.  A leading '0x' or '0X' denotes hexadecimal.  Otherwise,
+numbers take the form [BASE'#']N, where the optional BASE is a decimal
+number between 2 and 64 representing the arithmetic base, and N is a
+number in that base.  If BASE'#' is omitted, then base 10 is used.  When
+specifying N, if a non-digit is required, the digits greater than 9 are
+represented by the lowercase letters, the uppercase letters, '@', and
+'_', in that order.  If BASE is less than or equal to 36, lowercase and
+uppercase letters may be used interchangeably to represent numbers
+between 10 and 35.
+
+   Operators are evaluated in order of precedence.  Sub-expressions in
+parentheses are evaluated first and may override the precedence rules
+above.
+
+
+File: bashref.info,  Node: Aliases,  Next: Arrays,  Prev: Shell Arithmetic,  Up: Bash Features
+
+6.6 Aliases
+===========
+
+"Aliases" allow a string to be substituted for a word when it is used as
+the first word of a simple command.  The shell maintains a list of
+aliases that may be set and unset with the 'alias' and 'unalias' builtin
+commands.
+
+   The first word of each simple command, if unquoted, is checked to see
+if it has an alias.  If so, that word is replaced by the text of the
+alias.  The characters '/', '$', '`', '=' and any of the shell
+metacharacters or quoting characters listed above may not appear in an
+alias name.  The replacement text may contain any valid shell input,
+including shell metacharacters.  The first word of the replacement text
+is tested for aliases, but a word that is identical to an alias being
+expanded is not expanded a second time.  This means that one may alias
+'ls' to '"ls -F"', for instance, and Bash does not try to recursively
+expand the replacement text.  If the last character of the alias value
+is a 'blank', then the next command word following the alias is also
+checked for alias expansion.
+
+   Aliases are created and listed with the 'alias' command, and removed
+with the 'unalias' command.
+
+   There is no mechanism for using arguments in the replacement text, as
+in 'csh'.  If arguments are needed, use a shell function (*note Shell
+Functions::).
+
+   Aliases are not expanded when the shell is not interactive, unless
+the 'expand_aliases' shell option is set using 'shopt' (*note The Shopt
+Builtin::).
+
+   The rules concerning the definition and use of aliases are somewhat
+confusing.  Bash always reads at least one complete line of input, and
+all lines that make up a compound command, before executing any of the
+commands on that line or the compound command.  Aliases are expanded
+when a command is read, not when it is executed.  Therefore, an alias
+definition appearing on the same line as another command does not take
+effect until the next line of input is read.  The commands following the
+alias definition on that line are not affected by the new alias.  This
+behavior is also an issue when functions are executed.  Aliases are
+expanded when a function definition is read, not when the function is
+executed, because a function definition is itself a command.  As a
+consequence, aliases defined in a function are not available until after
+that function is executed.  To be safe, always put alias definitions on
+a separate line, and do not use 'alias' in compound commands.
+
+   For almost every purpose, shell functions are preferred over aliases.
+

+
+6.7 Arrays
+==========
+
+Bash provides one-dimensional indexed and associative array variables.
+Any variable may be used as an indexed array; the 'declare' builtin will
+explicitly declare an array.  There is no maximum limit on the size of
+an array, nor any requirement that members be indexed or assigned
+contiguously.  Indexed arrays are referenced using integers (including
+arithmetic expressions (*note Shell Arithmetic::)) and are zero-based;
+associative arrays use arbitrary strings.  Unless otherwise noted,
+indexed array indices must be non-negative integers.
+
+   An indexed array is created automatically if any variable is assigned
+to using the syntax
+     NAME[SUBSCRIPT]=VALUE
+
+The SUBSCRIPT is treated as an arithmetic expression that must evaluate
+to a number.  To explicitly declare an array, use
+     declare -a NAME
+The syntax
+     declare -a NAME[SUBSCRIPT]
+is also accepted; the SUBSCRIPT is ignored.
+
+Associative arrays are created using
+     declare -A NAME
+
+   Attributes may be specified for an array variable using the 'declare'
+and 'readonly' builtins.  Each attribute applies to all members of an
+array.
+
+   Arrays are assigned to using compound assignments of the form
+     NAME=(VALUE1 VALUE2 ... )
+where each VALUE may be of the form '[SUBSCRIPT]='STRING.  Indexed array
+assignments do not require anything but STRING.  When assigning to
+indexed arrays, if the optional subscript is supplied, that index is
+assigned to; otherwise the index of the element assigned is the last
+index assigned to by the statement plus one.  Indexing starts at zero.
+
+   Each VALUE in the list undergoes all the shell expansions described
+above (*note Shell Expansions::).
+
+   When assigning to an associative array, the words in a compound
+assignment may be either assignment statements, for which the subscript
+is required, or a list of words that is interpreted as a sequence of
+alternating keys and values: NAME=(KEY1 VALUE1 KEY2 VALUE2 ... ).  These
+are treated identically to NAME=( [KEY1]=VALUE1 [KEY2]=VALUE2 ... ).
+The first word in the list determines how the remaining words are
+interpreted; all assignments in a list must be of the same type.  When
+using key/value pairs, the keys may not be missing or empty; a final
+missing value is treated like the empty string.
+
+   This syntax is also accepted by the 'declare' builtin.  Individual
+array elements may be assigned to using the 'NAME[SUBSCRIPT]=VALUE'
+syntax introduced above.
+
+   When assigning to an indexed array, if NAME is subscripted by a
+negative number, that number is interpreted as relative to one greater
+than the maximum index of NAME, so negative indices count back from the
+end of the array, and an index of -1 references the last element.
+
+   The '+=' operator will append to an array variable when assigning
+using the compound assignment syntax; see *note Shell Parameters::
+above.
+
+   Any element of an array may be referenced using '${NAME[SUBSCRIPT]}'.
+The braces are required to avoid conflicts with the shell's filename
+expansion operators.  If the SUBSCRIPT is '@' or '*', the word expands
+to all members of the array NAME.  These subscripts differ only when the
+word appears within double quotes.  If the word is double-quoted,
+'${NAME[*]}' expands to a single word with the value of each array
+member separated by the first character of the 'IFS' variable, and
+'${NAME[@]}' expands each element of NAME to a separate word.  When
+there are no array members, '${NAME[@]}' expands to nothing.  If the
+double-quoted expansion occurs within a word, the expansion of the first
+parameter is joined with the beginning part of the original word, and
+the expansion of the last parameter is joined with the last part of the
+original word.  This is analogous to the expansion of the special
+parameters '@' and '*'.  '${#NAME[SUBSCRIPT]}' expands to the length of
+'${NAME[SUBSCRIPT]}'.  If SUBSCRIPT is '@' or '*', the expansion is the
+number of elements in the array.  If the SUBSCRIPT used to reference an
+element of an indexed array evaluates to a number less than zero, it is
+interpreted as relative to one greater than the maximum index of the
+array, so negative indices count back from the end of the array, and an
+index of -1 refers to the last element.
+
+   Referencing an array variable without a subscript is equivalent to
+referencing with a subscript of 0.  Any reference to a variable using a
+valid subscript is legal, and 'bash' will create an array if necessary.
+
+   An array variable is considered set if a subscript has been assigned
+a value.  The null string is a valid value.
+
+   It is possible to obtain the keys (indices) of an array as well as
+the values.  ${!NAME[@]} and ${!NAME[*]} expand to the indices assigned
+in array variable NAME.  The treatment when in double quotes is similar
+to the expansion of the special parameters '@' and '*' within double
+quotes.
+
+   The 'unset' builtin is used to destroy arrays.  'unset
+NAME[SUBSCRIPT]' destroys the array element at index SUBSCRIPT.
+Negative subscripts to indexed arrays are interpreted as described
+above.  Unsetting the last element of an array variable does not unset
+the variable.  'unset NAME', where NAME is an array, removes the entire
+array.  'unset NAME[SUBSCRIPT]' behaves differently depending on the
+array type when given a subscript of '*' or '@'.  When NAME is an
+associative array, it removes the element with key '*' or '@'.  If NAME
+is an indexed array, 'unset' removes all of the elements, but does not
+remove the array itself.
+
+   When using a variable name with a subscript as an argument to a
+command, such as with 'unset', without using the word expansion syntax
+described above, the argument is subject to the shell's filename
+expansion.  If filename expansion is not desired, the argument should be
+quoted.
+
+   The 'declare', 'local', and 'readonly' builtins each accept a '-a'
+option to specify an indexed array and a '-A' option to specify an
+associative array.  If both options are supplied, '-A' takes precedence.
+The 'read' builtin accepts a '-a' option to assign a list of words read
+from the standard input to an array, and can read values from the
+standard input into individual array elements.  The 'set' and 'declare'
+builtins display array values in a way that allows them to be reused as
+input.

+6.8 The Directory Stack
+=======================
+
+* Menu:
+
+* Directory Stack Builtins::		Bash builtin commands to manipulate
+					the directory stack.
+
+The directory stack is a list of recently-visited directories.  The
+'pushd' builtin adds directories to the stack as it changes the current
+directory, and the 'popd' builtin removes specified directories from the
+stack and changes the current directory to the directory removed.  The
+'dirs' builtin displays the contents of the directory stack.  The
+current directory is always the "top" of the directory stack.
+
+   The contents of the directory stack are also visible as the value of
+the 'DIRSTACK' shell variable.
+
+
+File: bashref.info,  Node: Directory Stack Builtins,  Up: The Directory Stack
+
+6.8.1 Directory Stack Builtins
+------------------------------
+
+'dirs'
+          dirs [-clpv] [+N | -N]
+
+     Display the list of currently remembered directories.  Directories
+     are added to the list with the 'pushd' command; the 'popd' command
+     removes directories from the list.  The current directory is always
+     the first directory in the stack.
+
+     '-c'
+          Clears the directory stack by deleting all of the elements.
+     '-l'
+          Produces a listing using full pathnames; the default listing
+          format uses a tilde to denote the home directory.
+     '-p'
+          Causes 'dirs' to print the directory stack with one entry per
+          line.
+     '-v'
+          Causes 'dirs' to print the directory stack with one entry per
+          line, prefixing each entry with its index in the stack.
+     '+N'
+          Displays the Nth directory (counting from the left of the list
+          printed by 'dirs' when invoked without options), starting with
+          zero.
+     '-N'
+          Displays the Nth directory (counting from the right of the
+          list printed by 'dirs' when invoked without options), starting
+          with zero.
+
+'popd'
+          popd [-n] [+N | -N]
+
+     Removes elements from the directory stack.  The elements are
+     numbered from 0 starting at the first directory listed by 'dirs';
+     that is, 'popd' is equivalent to 'popd +0'.
+
+     When no arguments are given, 'popd' removes the top directory from
+     the stack and changes to the new top directory.
+
+     Arguments, if supplied, have the following meanings:
+
+     '-n'
+          Suppresses the normal change of directory when removing
+          directories from the stack, so that only the stack is
+          manipulated.
+     '+N'
+          Removes the Nth directory (counting from the left of the list
+          printed by 'dirs'), starting with zero, from the stack.
+     '-N'
+          Removes the Nth directory (counting from the right of the list
+          printed by 'dirs'), starting with zero, from the stack.
+
+     If the top element of the directory stack is modified, and the '-n'
+     option was not supplied, 'popd' uses the 'cd' builtin to change to
+     the directory at the top of the stack.  If the 'cd' fails, 'popd'
+     returns a non-zero value.
+
+     Otherwise, 'popd' returns an unsuccessful status if an invalid
+     option is encountered, the directory stack is empty, or a
+     non-existent directory stack entry is specified.
+
+     If the 'popd' command is successful, Bash runs 'dirs' to show the
+     final contents of the directory stack, and the return status is 0.
+
+'pushd'
+          pushd [-n] [+N | -N | DIR]
+
+     Adds a directory to the top of the directory stack, or rotates the
+     stack, making the new top of the stack the current working
+     directory.  With no arguments, 'pushd' exchanges the top two
+     elements of the directory stack.
+
+     Arguments, if supplied, have the following meanings:
+
+     '-n'
+          Suppresses the normal change of directory when rotating or
+          adding directories to the stack, so that only the stack is
+          manipulated.
+     '+N'
+          Brings the Nth directory (counting from the left of the list
+          printed by 'dirs', starting with zero) to the top of the list
+          by rotating the stack.
+     '-N'
+          Brings the Nth directory (counting from the right of the list
+          printed by 'dirs', starting with zero) to the top of the list
+          by rotating the stack.
+     'DIR'
+          Makes DIR be the top of the stack.
+
+     After the stack has been modified, if the '-n' option was not
+     supplied, 'pushd' uses the 'cd' builtin to change to the directory
+     at the top of the stack.  If the 'cd' fails, 'pushd' returns a
+     non-zero value.
+
+     Otherwise, if no arguments are supplied, 'pushd' returns 0 unless
+     the directory stack is empty.  When rotating the directory stack,
+     'pushd' returns 0 unless the directory stack is empty or a
+     non-existent directory stack element is specified.
+
+     If the 'pushd' command is successful, Bash runs 'dirs' to show the
+     final contents of the directory stack.

+
+6.9 Controlling the Prompt
+==========================
+
+Bash examines the value of the array variable 'PROMPT_COMMAND' just
+before printing each primary prompt.  If any elements in
+'PROMPT_COMMAND' are set and non-null, Bash executes each value, in
+numeric order, just as if it had been typed on the command line.
+
+   In addition, the following table describes the special characters
+which can appear in the prompt variables 'PS0', 'PS1', 'PS2', and 'PS4':
+
+'\a'
+     A bell character.
+'\d'
+     The date, in "Weekday Month Date" format (e.g., "Tue May 26").
+'\D{FORMAT}'
+     The FORMAT is passed to 'strftime'(3) and the result is inserted
+     into the prompt string; an empty FORMAT results in a
+     locale-specific time representation.  The braces are required.
+'\e'
+     An escape character.
+'\h'
+     The hostname, up to the first '.'.
+'\H'
+     The hostname.
+'\j'
+     The number of jobs currently managed by the shell.
+'\l'
+     The basename of the shell's terminal device name.
+'\n'
+     A newline.
+'\r'
+     A carriage return.
+'\s'
+     The name of the shell, the basename of '$0' (the portion following
+     the final slash).
+'\t'
+     The time, in 24-hour HH:MM:SS format.
+'\T'
+     The time, in 12-hour HH:MM:SS format.
+'\@'
+     The time, in 12-hour am/pm format.
+'\A'
+     The time, in 24-hour HH:MM format.
+'\u'
+     The username of the current user.
+'\v'
+     The version of Bash (e.g., 2.00)
+'\V'
+     The release of Bash, version + patchlevel (e.g., 2.00.0)
+'\w'
+     The value of the 'PWD' shell variable ('$PWD'), with '$HOME'
+     abbreviated with a tilde (uses the '$PROMPT_DIRTRIM' variable).
+'\W'
+     The basename of '$PWD', with '$HOME' abbreviated with a tilde.
+'\!'
+     The history number of this command.
+'\#'
+     The command number of this command.
+'\$'
+     If the effective uid is 0, '#', otherwise '$'.
+'\NNN'
+     The character whose ASCII code is the octal value NNN.
+'\\'
+     A backslash.
+'\['
+     Begin a sequence of non-printing characters.  This could be used to
+     embed a terminal control sequence into the prompt.
+'\]'
+     End a sequence of non-printing characters.
+
+   The command number and the history number are usually different: the
+history number of a command is its position in the history list, which
+may include commands restored from the history file (*note Bash History
+Facilities::), while the command number is the position in the sequence
+of commands executed during the current shell session.
+
+   After the string is decoded, it is expanded via parameter expansion,
+command substitution, arithmetic expansion, and quote removal, subject
+to the value of the 'promptvars' shell option (*note The Shopt
+Builtin::).  This can have unwanted side effects if escaped portions of
+the string appear within command substitution or contain characters
+special to word expansion.

+
+6.10 The Restricted Shell
+=========================
+
+If Bash is started with the name 'rbash', or the '--restricted' or '-r'
+option is supplied at invocation, the shell becomes restricted.  A
+restricted shell is used to set up an environment more controlled than
+the standard shell.  A restricted shell behaves identically to 'bash'
+with the exception that the following are disallowed or not performed:
+
+   * Changing directories with the 'cd' builtin.
+   * Setting or unsetting the values of the 'SHELL', 'PATH', 'HISTFILE',
+     'ENV', or 'BASH_ENV' variables.
+   * Specifying command names containing slashes.
+   * Specifying a filename containing a slash as an argument to the '.'
+     builtin command.
+   * Specifying a filename containing a slash as an argument to the
+     'history' builtin command.
+   * Specifying a filename containing a slash as an argument to the '-p'
+     option to the 'hash' builtin command.
+   * Importing function definitions from the shell environment at
+     startup.
+   * Parsing the value of 'SHELLOPTS' from the shell environment at
+     startup.
+   * Redirecting output using the '>', '>|', '<>', '>&', '&>', and '>>'
+     redirection operators.
+   * Using the 'exec' builtin to replace the shell with another command.
+   * Adding or deleting builtin commands with the '-f' and '-d' options
+     to the 'enable' builtin.
+   * Using the 'enable' builtin command to enable disabled shell
+     builtins.
+   * Specifying the '-p' option to the 'command' builtin.
+   * Turning off restricted mode with 'set +r' or 'shopt -u
+     restricted_shell'.
+
+   These restrictions are enforced after any startup files are read.
+
+   When a command that is found to be a shell script is executed (*note
+Shell Scripts::), 'rbash' turns off any restrictions in the shell
+spawned to execute the script.
+
+   The restricted shell mode is only one component of a useful
+restricted environment.  It should be accompanied by setting 'PATH' to a
+value that allows execution of only a few verified commands (commands
+that allow shell escapes are particularly vulnerable), changing the
+current directory to a non-writable directory other than '$HOME' after
+login, not allowing the restricted shell to execute shell scripts, and
+cleaning the environment of variables that cause some commands to modify
+their behavior (e.g., 'VISUAL' or 'PAGER').
+
+   Modern systems provide more secure ways to implement a restricted
+environment, such as 'jails', 'zones', or 'containers'.
+
+
+File: bashref.info,  Node: Bash POSIX Mode,  Next: Shell Compatibility Mode,  Prev: The Restricted Shell,  Up: Bash Features
+
+6.11 Bash POSIX Mode
+====================
+
+Starting Bash with the '--posix' command-line option or executing 'set
+-o posix' while Bash is running will cause Bash to conform more closely
+to the POSIX standard by changing the behavior to match that specified
+by POSIX in areas where the Bash default differs.
+
+   When invoked as 'sh', Bash enters POSIX mode after reading the
+startup files.
+
+   The following list is what's changed when 'POSIX mode' is in effect:
+
+  1. Bash ensures that the 'POSIXLY_CORRECT' variable is set.
+
+  2. When a command in the hash table no longer exists, Bash will
+     re-search '$PATH' to find the new location.  This is also available
+     with 'shopt -s checkhash'.
+
+  3. Bash will not insert a command without the execute bit set into the
+     command hash table, even if it returns it as a (last-ditch) result
+     from a '$PATH' search.
+
+  4. The message printed by the job control code and builtins when a job
+     exits with a non-zero status is 'Done(status)'.
+
+  5. The message printed by the job control code and builtins when a job
+     is stopped is 'Stopped(SIGNAME)', where SIGNAME is, for example,
+     'SIGTSTP'.
+
+  6. Alias expansion is always enabled, even in non-interactive shells.
+
+  7. Reserved words appearing in a context where reserved words are
+     recognized do not undergo alias expansion.
+
+  8. Alias expansion is performed when initially parsing a command
+     substitution.  The default mode generally defers it, when enabled,
+     until the command substitution is executed.  This means that
+     command substitution will not expand aliases that are defined after
+     the command substitution is initially parsed (e.g., as part of a
+     function definition).
+
+  9. The POSIX 'PS1' and 'PS2' expansions of '!' to the history number
+     and '!!' to '!' are enabled, and parameter expansion is performed
+     on the values of 'PS1' and 'PS2' regardless of the setting of the
+     'promptvars' option.
+
+  10. The POSIX startup files are executed ('$ENV') rather than the
+     normal Bash files.
+
+  11. Tilde expansion is only performed on assignments preceding a
+     command name, rather than on all assignment statements on the line.
+
+  12. The default history file is '~/.sh_history' (this is the default
+     value of '$HISTFILE').
+
+  13. Redirection operators do not perform filename expansion on the
+     word in the redirection unless the shell is interactive.
+
+  14. Redirection operators do not perform word splitting on the word in
+     the redirection.
+
+  15. Function names must be valid shell 'name's.  That is, they may not
+     contain characters other than letters, digits, and underscores, and
+     may not start with a digit.  Declaring a function with an invalid
+     name causes a fatal syntax error in non-interactive shells.
+
+  16. Function names may not be the same as one of the POSIX special
+     builtins.
+
+  17. POSIX special builtins are found before shell functions during
+     command lookup.
+
+  18. When printing shell function definitions (e.g., by 'type'), Bash
+     does not print the 'function' keyword.
+
+  19. Literal tildes that appear as the first character in elements of
+     the 'PATH' variable are not expanded as described above under *note
+     Tilde Expansion::.
+
+  20. The 'time' reserved word may be used by itself as a command.  When
+     used in this way, it displays timing statistics for the shell and
+     its completed children.  The 'TIMEFORMAT' variable controls the
+     format of the timing information.
+
+  21. When parsing and expanding a ${...} expansion that appears within
+     double quotes, single quotes are no longer special and cannot be
+     used to quote a closing brace or other special character, unless
+     the operator is one of those defined to perform pattern removal.
+     In this case, they do not have to appear as matched pairs.
+
+  22. The parser does not recognize 'time' as a reserved word if the
+     next token begins with a '-'.
+
+  23. The '!' character does not introduce history expansion within a
+     double-quoted string, even if the 'histexpand' option is enabled.
+
+  24. If a POSIX special builtin returns an error status, a
+     non-interactive shell exits.  The fatal errors are those listed in
+     the POSIX standard, and include things like passing incorrect
+     options, redirection errors, variable assignment errors for
+     assignments preceding the command name, and so on.
+
+  25. A non-interactive shell exits with an error status if a variable
+     assignment error occurs when no command name follows the assignment
+     statements.  A variable assignment error occurs, for example, when
+     trying to assign a value to a readonly variable.
+
+  26. A non-interactive shell exits with an error status if a variable
+     assignment error occurs in an assignment statement preceding a
+     special builtin, but not with any other simple command.  For any
+     other simple command, the shell aborts execution of that command,
+     and execution continues at the top level ("the shell shall not
+     perform any further processing of the command in which the error
+     occurred").
+
+  27. A non-interactive shell exits with an error status if the
+     iteration variable in a 'for' statement or the selection variable
+     in a 'select' statement is a readonly variable.
+
+  28. Non-interactive shells exit if FILENAME in '.'  FILENAME is not
+     found.
+
+  29. Non-interactive shells exit if a syntax error in an arithmetic
+     expansion results in an invalid expression.
+
+  30. Non-interactive shells exit if a parameter expansion error occurs.
+
+  31. Non-interactive shells exit if there is a syntax error in a script
+     read with the '.' or 'source' builtins, or in a string processed by
+     the 'eval' builtin.
+
+  32. While variable indirection is available, it may not be applied to
+     the '#' and '?' special parameters.
+
+  33. Expanding the '*' special parameter in a pattern context where the
+     expansion is double-quoted does not treat the '$*' as if it were
+     double-quoted.
+
+  34. Assignment statements preceding POSIX special builtins persist in
+     the shell environment after the builtin completes.
+
+  35. The 'command' builtin does not prevent builtins that take
+     assignment statements as arguments from expanding them as
+     assignment statements; when not in POSIX mode, assignment builtins
+     lose their assignment statement expansion properties when preceded
+     by 'command'.
+
+  36. The 'bg' builtin uses the required format to describe each job
+     placed in the background, which does not include an indication of
+     whether the job is the current or previous job.
+
+  37. The output of 'kill -l' prints all the signal names on a single
+     line, separated by spaces, without the 'SIG' prefix.
+
+  38. The 'kill' builtin does not accept signal names with a 'SIG'
+     prefix.
+
+  39. The 'export' and 'readonly' builtin commands display their output
+     in the format required by POSIX.
+
+  40. The 'trap' builtin displays signal names without the leading
+     'SIG'.
+
+  41. The 'trap' builtin doesn't check the first argument for a possible
+     signal specification and revert the signal handling to the original
+     disposition if it is, unless that argument consists solely of
+     digits and is a valid signal number.  If users want to reset the
+     handler for a given signal to the original disposition, they should
+     use '-' as the first argument.
+
+  42. 'trap -p' displays signals whose dispositions are set to SIG_DFL
+     and those that were ignored when the shell started.
+
+  43. The '.' and 'source' builtins do not search the current directory
+     for the filename argument if it is not found by searching 'PATH'.
+
+  44. Enabling POSIX mode has the effect of setting the
+     'inherit_errexit' option, so subshells spawned to execute command
+     substitutions inherit the value of the '-e' option from the parent
+     shell.  When the 'inherit_errexit' option is not enabled, Bash
+     clears the '-e' option in such subshells.
+
+  45. Enabling POSIX mode has the effect of setting the 'shift_verbose'
+     option, so numeric arguments to 'shift' that exceed the number of
+     positional parameters will result in an error message.
+
+  46. When the 'alias' builtin displays alias definitions, it does not
+     display them with a leading 'alias ' unless the '-p' option is
+     supplied.
+
+  47. When the 'set' builtin is invoked without options, it does not
+     display shell function names and definitions.
+
+  48. When the 'set' builtin is invoked without options, it displays
+     variable values without quotes, unless they contain shell
+     metacharacters, even if the result contains nonprinting characters.
+
+  49. When the 'cd' builtin is invoked in logical mode, and the pathname
+     constructed from '$PWD' and the directory name supplied as an
+     argument does not refer to an existing directory, 'cd' will fail
+     instead of falling back to physical mode.
+
+  50. When the 'cd' builtin cannot change a directory because the length
+     of the pathname constructed from '$PWD' and the directory name
+     supplied as an argument exceeds 'PATH_MAX' when all symbolic links
+     are expanded, 'cd' will fail instead of attempting to use only the
+     supplied directory name.
+
+  51. The 'pwd' builtin verifies that the value it prints is the same as
+     the current directory, even if it is not asked to check the file
+     system with the '-P' option.
+
+  52. When listing the history, the 'fc' builtin does not include an
+     indication of whether or not a history entry has been modified.
+
+  53. The default editor used by 'fc' is 'ed'.
+
+  54. The 'type' and 'command' builtins will not report a non-executable
+     file as having been found, though the shell will attempt to execute
+     such a file if it is the only so-named file found in '$PATH'.
+
+  55. The 'vi' editing mode will invoke the 'vi' editor directly when
+     the 'v' command is run, instead of checking '$VISUAL' and
+     '$EDITOR'.
+
+  56. When the 'xpg_echo' option is enabled, Bash does not attempt to
+     interpret any arguments to 'echo' as options.  Each argument is
+     displayed, after escape characters are converted.
+
+  57. The 'ulimit' builtin uses a block size of 512 bytes for the '-c'
+     and '-f' options.
+
+  58. The arrival of 'SIGCHLD' when a trap is set on 'SIGCHLD' does not
+     interrupt the 'wait' builtin and cause it to return immediately.
+     The trap command is run once for each child that exits.
+
+  59. The 'read' builtin may be interrupted by a signal for which a trap
+     has been set.  If Bash receives a trapped signal while executing
+     'read', the trap handler executes and 'read' returns an exit status
+     greater than 128.
+
+  60. The 'printf' builtin uses 'double' (via 'strtod') to convert
+     arguments corresponding to floating point conversion specifiers,
+     instead of 'long double' if it's available.  The 'L' length
+     modifier forces 'printf' to use 'long double' if it's available.
+
+  61. Bash removes an exited background process's status from the list
+     of such statuses after the 'wait' builtin is used to obtain it.
+
+   There is other POSIX behavior that Bash does not implement by default
+even when in POSIX mode.  Specifically:
+
+  1. The 'fc' builtin checks '$EDITOR' as a program to edit history
+     entries if 'FCEDIT' is unset, rather than defaulting directly to
+     'ed'.  'fc' uses 'ed' if 'EDITOR' is unset.
+
+  2. As noted above, Bash requires the 'xpg_echo' option to be enabled
+     for the 'echo' builtin to be fully conformant.
+
+   Bash can be configured to be POSIX-conformant by default, by
+specifying the '--enable-strict-posix-default' to 'configure' when
+building (*note Optional Features::).

+
+6.12 Shell Compatibility Mode
+=============================
+
+Bash-4.0 introduced the concept of a "shell compatibility level",
+specified as a set of options to the shopt builtin ('compat31',
+'compat32', 'compat40', 'compat41', and so on).  There is only one
+current compatibility level - each option is mutually exclusive.  The
+compatibility level is intended to allow users to select behavior from
+previous versions that is incompatible with newer versions while they
+migrate scripts to use current features and behavior.  It's intended to
+be a temporary solution.
+
+   This section does not mention behavior that is standard for a
+particular version (e.g., setting 'compat32' means that quoting the rhs
+of the regexp matching operator quotes special regexp characters in the
+word, which is default behavior in bash-3.2 and subsequent versions).
+
+   If a user enables, say, 'compat32', it may affect the behavior of
+other compatibility levels up to and including the current compatibility
+level.  The idea is that each compatibility level controls behavior that
+changed in that version of Bash, but that behavior may have been present
+in earlier versions.  For instance, the change to use locale-based
+comparisons with the '[[' command came in bash-4.1, and earlier versions
+used ASCII-based comparisons, so enabling 'compat32' will enable
+ASCII-based comparisons as well.  That granularity may not be sufficient
+for all uses, and as a result users should employ compatibility levels
+carefully.  Read the documentation for a particular feature to find out
+the current behavior.
+
+   Bash-4.3 introduced a new shell variable: 'BASH_COMPAT'.  The value
+assigned to this variable (a decimal version number like 4.2, or an
+integer corresponding to the 'compat'NN option, like 42) determines the
+compatibility level.
+
+   Starting with bash-4.4, Bash has begun deprecating older
+compatibility levels.  Eventually, the options will be removed in favor
+of 'BASH_COMPAT'.
+
+   Bash-5.0 is the final version for which there will be an individual
+shopt option for the previous version.  Users should use 'BASH_COMPAT'
+on bash-5.0 and later versions.
+
+   The following table describes the behavior changes controlled by each
+compatibility level setting.  The 'compat'NN tag is used as shorthand
+for setting the compatibility level to NN using one of the following
+mechanisms.  For versions prior to bash-5.0, the compatibility level may
+be set using the corresponding 'compat'NN shopt option.  For bash-4.3
+and later versions, the 'BASH_COMPAT' variable is preferred, and it is
+required for bash-5.1 and later versions.
+
+'compat31'
+        * quoting the rhs of the '[[' command's regexp matching operator
+          (=~) has no special effect
+
+'compat32'
+        * interrupting a command list such as "a ; b ; c" causes the
+          execution of the next command in the list (in bash-4.0 and
+          later versions, the shell acts as if it received the
+          interrupt, so interrupting one command in a list aborts the
+          execution of the entire list)
+
+'compat40'
+        * the '<' and '>' operators to the '[[' command do not consider
+          the current locale when comparing strings; they use ASCII
+          ordering.  Bash versions prior to bash-4.1 use ASCII collation
+          and strcmp(3); bash-4.1 and later use the current locale's
+          collation sequence and strcoll(3).
+
+'compat41'
+        * in posix mode, 'time' may be followed by options and still be
+          recognized as a reserved word (this is POSIX interpretation
+          267)
+        * in posix mode, the parser requires that an even number of
+          single quotes occur in the WORD portion of a double-quoted
+          ${...} parameter expansion and treats them specially, so that
+          characters within the single quotes are considered quoted
+          (this is POSIX interpretation 221)
+
+'compat42'
+        * the replacement string in double-quoted pattern substitution
+          does not undergo quote removal, as it does in versions after
+          bash-4.2
+        * in posix mode, single quotes are considered special when
+          expanding the WORD portion of a double-quoted ${...} parameter
+          expansion and can be used to quote a closing brace or other
+          special character (this is part of POSIX interpretation 221);
+          in later versions, single quotes are not special within
+          double-quoted word expansions
+
+'compat43'
+        * the shell does not print a warning message if an attempt is
+          made to use a quoted compound assignment as an argument to
+          declare (e.g., declare -a foo='(1 2)').  Later versions warn
+          that this usage is deprecated
+        * word expansion errors are considered non-fatal errors that
+          cause the current command to fail, even in posix mode (the
+          default behavior is to make them fatal errors that cause the
+          shell to exit)
+        * when executing a shell function, the loop state
+          (while/until/etc.)  is not reset, so 'break' or 'continue' in
+          that function will break or continue loops in the calling
+          context.  Bash-4.4 and later reset the loop state to prevent
+          this
+
+'compat44'
+        * the shell sets up the values used by 'BASH_ARGV' and
+          'BASH_ARGC' so they can expand to the shell's positional
+          parameters even if extended debugging mode is not enabled
+        * a subshell inherits loops from its parent context, so 'break'
+          or 'continue' will cause the subshell to exit.  Bash-5.0 and
+          later reset the loop state to prevent the exit
+        * variable assignments preceding builtins like 'export' and
+          'readonly' that set attributes continue to affect variables
+          with the same name in the calling environment even if the
+          shell is not in posix mode
+
+'compat50 (set using BASH_COMPAT)'
+        * Bash-5.1 changed the way '$RANDOM' is generated to introduce
+          slightly more randomness.  If the shell compatibility level is
+          set to 50 or lower, it reverts to the method from bash-5.0 and
+          previous versions, so seeding the random number generator by
+          assigning a value to 'RANDOM' will produce the same sequence
+          as in bash-5.0
+        * If the command hash table is empty, Bash versions prior to
+          bash-5.1 printed an informational message to that effect, even
+          when producing output that can be reused as input.  Bash-5.1
+          suppresses that message when the '-l' option is supplied.
+
+'compat51 (set using BASH_COMPAT)'
+        * The 'unset' builtin will unset the array 'a' given an argument
+          like 'a[@]'.  Bash-5.2 will unset an element with key '@'
+          (associative arrays) or remove all the elements without
+          unsetting the array (indexed arrays)
+        * arithmetic commands ( ((...))  )  and the expressions in an
+          arithmetic for statement can be expanded more than once
+        * expressions used as arguments to arithmetic operators in the
+          '[[' conditional command can be expanded more than once
+        * the expressions in substring parameter brace expansion can be
+          expanded more than once
+        * the expressions in the $(( ...  ))  word expansion can be
+          expanded more than once
+        * arithmetic expressions used as indexed array subscripts can be
+          expanded more than once
+        * 'test -v', when given an argument of 'A[@]', where A is an
+          existing associative array, will return true if the array has
+          any set elements.  Bash-5.2 will look for and report on a key
+          named '@'
+        * the ${PARAMETER[:]=VALUE} word expansion will return VALUE,
+          before any variable-specific transformations have been
+          performed (e.g., converting to lowercase).  Bash-5.2 will
+          return the final value assigned to the variable.
+        * Parsing command substitutions will behave as if extended glob
+          (*note The Shopt Builtin::) is enabled, so that parsing a
+          command substitution containing an extglob pattern (say, as
+          part of a shell function) will not fail.  This assumes the
+          intent is to enable extglob before the command is executed and
+          word expansions are performed.  It will fail at word expansion
+          time if extglob hasn't been enabled by the time the command is
+          executed.

+7 Job Control
+*************
+
+This chapter discusses what job control is, how it works, and how Bash
+allows you to access its facilities.
+
+* Menu:

+* Job Control Basics::		How job control works.
+* Job Control Builtins::	Bash builtin commands used to interact

+* Job Control Variables::	Variables Bash uses to customize job
+				control.
+
+
+File: bashref.info,  Node: Job Control Basics,  Next: Job Control Builtins,  Up: Job Control
+
+7.1 Job Control Basics
+======================
+
+Job control refers to the ability to selectively stop (suspend) the
+execution of processes and continue (resume) their execution at a later
+point.  A user typically employs this facility via an interactive
+interface supplied jointly by the operating system kernel's terminal
+driver and Bash.
+
+   The shell associates a JOB with each pipeline.  It keeps a table of
+currently executing jobs, which may be listed with the 'jobs' command.
+When Bash starts a job asynchronously, it prints a line that looks like:
+     [1] 25647
+indicating that this job is job number 1 and that the process ID of the
+last process in the pipeline associated with this job is 25647.  All of
+the processes in a single pipeline are members of the same job.  Bash
+uses the JOB abstraction as the basis for job control.
+
+   To facilitate the implementation of the user interface to job
+control, the operating system maintains the notion of a current terminal
+process group ID.  Members of this process group (processes whose
+process group ID is equal to the current terminal process group ID)
+receive keyboard-generated signals such as 'SIGINT'.  These processes
+are said to be in the foreground.  Background processes are those whose
+process group ID differs from the terminal's; such processes are immune
+to keyboard-generated signals.  Only foreground processes are allowed to
+read from or, if the user so specifies with 'stty tostop', write to the
+terminal.  Background processes which attempt to read from (write to
+when 'stty tostop' is in effect) the terminal are sent a 'SIGTTIN'
+('SIGTTOU') signal by the kernel's terminal driver, which, unless
+caught, suspends the process.
+
+   If the operating system on which Bash is running supports job
+control, Bash contains facilities to use it.  Typing the "suspend"
+character (typically '^Z', Control-Z) while a process is running causes
+that process to be stopped and returns control to Bash.  Typing the
+"delayed suspend" character (typically '^Y', Control-Y) causes the
+process to be stopped when it attempts to read input from the terminal,
+and control to be returned to Bash.  The user then manipulates the state
+of this job, using the 'bg' command to continue it in the background,
+the 'fg' command to continue it in the foreground, or the 'kill' command
+to kill it.  A '^Z' takes effect immediately, and has the additional
+side effect of causing pending output and typeahead to be discarded.
+
+   There are a number of ways to refer to a job in the shell.  The
+character '%' introduces a job specification ("jobspec").
+
+   Job number 'n' may be referred to as '%n'.  The symbols '%%' and '%+'
+refer to the shell's notion of the current job, which is the last job
+stopped while it was in the foreground or started in the background.  A
+single '%' (with no accompanying job specification) also refers to the
+current job.  The previous job may be referenced using '%-'.  If there
+is only a single job, '%+' and '%-' can both be used to refer to that
+job.  In output pertaining to jobs (e.g., the output of the 'jobs'
+command), the current job is always flagged with a '+', and the previous
+job with a '-'.
+
+   A job may also be referred to using a prefix of the name used to
+start it, or using a substring that appears in its command line.  For
+example, '%ce' refers to a stopped job whose command name begins with
+'ce'.  Using '%?ce', on the other hand, refers to any job containing the
+string 'ce' in its command line.  If the prefix or substring matches
+more than one job, Bash reports an error.
+
+   Simply naming a job can be used to bring it into the foreground: '%1'
+is a synonym for 'fg %1', bringing job 1 from the background into the
+foreground.  Similarly, '%1 &' resumes job 1 in the background,
+equivalent to 'bg %1'
+
+   The shell learns immediately whenever a job changes state.  Normally,
+Bash waits until it is about to print a prompt before reporting changes
+in a job's status so as to not interrupt any other output.  If the '-b'
+option to the 'set' builtin is enabled, Bash reports such changes
+immediately (*note The Set Builtin::).  Any trap on 'SIGCHLD' is
+executed for each child process that exits.
+
+   If an attempt to exit Bash is made while jobs are stopped, (or
+running, if the 'checkjobs' option is enabled - see *note The Shopt
+Builtin::), the shell prints a warning message, and if the 'checkjobs'
+option is enabled, lists the jobs and their statuses.  The 'jobs'
+command may then be used to inspect their status.  If a second attempt
+to exit is made without an intervening command, Bash does not print
+another warning, and any stopped jobs are terminated.
+
+   When the shell is waiting for a job or process using the 'wait'
+builtin, and job control is enabled, 'wait' will return when the job
+changes state.  The '-f' option causes 'wait' to wait until the job or
+process terminates before returning.

+
+7.2 Job Control Builtins
+========================
+
+'bg'
+          bg [JOBSPEC ...]
+
+     Resume each suspended job JOBSPEC in the background, as if it had
+     been started with '&'.  If JOBSPEC is not supplied, the current job
+     is used.  The return status is zero unless it is run when job
+     control is not enabled, or, when run with job control enabled, any
+     JOBSPEC was not found or specifies a job that was started without
+     job control.
+
+'fg'
+          fg [JOBSPEC]
+
+     Resume the job JOBSPEC in the foreground and make it the current
+     job.  If JOBSPEC is not supplied, the current job is used.  The
+     return status is that of the command placed into the foreground, or
+     non-zero if run when job control is disabled or, when run with job
+     control enabled, JOBSPEC does not specify a valid job or JOBSPEC
+     specifies a job that was started without job control.
+
+'jobs'
+          jobs [-lnprs] [JOBSPEC]
+          jobs -x COMMAND [ARGUMENTS]
+
+     The first form lists the active jobs.  The options have the
+     following meanings:
+
+     '-l'
+          List process IDs in addition to the normal information.
+
+     '-n'
+          Display information only about jobs that have changed status
+          since the user was last notified of their status.
+
+     '-p'
+          List only the process ID of the job's process group leader.
+
+     '-r'
+          Display only running jobs.
+
+     '-s'
+          Display only stopped jobs.
+
+     If JOBSPEC is given, output is restricted to information about that
+     job.  If JOBSPEC is not supplied, the status of all jobs is listed.
+
+     If the '-x' option is supplied, 'jobs' replaces any JOBSPEC found
+     in COMMAND or ARGUMENTS with the corresponding process group ID,
+     and executes COMMAND, passing it ARGUMENTs, returning its exit
+     status.
+
+'kill'
+          kill [-s SIGSPEC] [-n SIGNUM] [-SIGSPEC] JOBSPEC or PID
+          kill -l|-L [EXIT_STATUS]
+
+     Send a signal specified by SIGSPEC or SIGNUM to the process named
+     by job specification JOBSPEC or process ID PID.  SIGSPEC is either
+     a case-insensitive signal name such as 'SIGINT' (with or without
+     the 'SIG' prefix) or a signal number; SIGNUM is a signal number.
+     If SIGSPEC and SIGNUM are not present, 'SIGTERM' is used.  The '-l'
+     option lists the signal names.  If any arguments are supplied when
+     '-l' is given, the names of the signals corresponding to the
+     arguments are listed, and the return status is zero.  EXIT_STATUS
+     is a number specifying a signal number or the exit status of a
+     process terminated by a signal.  The '-L' option is equivalent to
+     '-l'.  The return status is zero if at least one signal was
+     successfully sent, or non-zero if an error occurs or an invalid
+     option is encountered.
+
+'wait'
+          wait [-fn] [-p VARNAME] [JOBSPEC or PID ...]
+
+     Wait until the child process specified by each process ID PID or
+     job specification JOBSPEC exits and return the exit status of the
+     last command waited for.  If a job spec is given, all processes in
+     the job are waited for.  If no arguments are given, 'wait' waits
+     for all running background jobs and the last-executed process
+     substitution, if its process id is the same as $!, and the return
+     status is zero.  If the '-n' option is supplied, 'wait' waits for a
+     single job from the list of PIDs or JOBSPECs or, if no arguments
+     are supplied, any job, to complete and returns its exit status.  If
+     none of the supplied arguments is a child of the shell, or if no
+     arguments are supplied and the shell has no unwaited-for children,
+     the exit status is 127.  If the '-p' option is supplied, the
+     process or job identifier of the job for which the exit status is
+     returned is assigned to the variable VARNAME named by the option
+     argument.  The variable will be unset initially, before any
+     assignment.  This is useful only when the '-n' option is supplied.
+     Supplying the '-f' option, when job control is enabled, forces
+     'wait' to wait for each PID or JOBSPEC to terminate before
+     returning its status, instead of returning when it changes status.
+     If neither JOBSPEC nor PID specifies an active child process of the
+     shell, the return status is 127.  If 'wait' is interrupted by a
+     signal, the return status will be greater than 128, as described
+     above (*note Signals::).  Otherwise, the return status is the exit
+     status of the last process or job waited for.
+
+'disown'
+          disown [-ar] [-h] [JOBSPEC ... | PID ... ]
+
+     Without options, remove each JOBSPEC from the table of active jobs.
+     If the '-h' option is given, the job is not removed from the table,
+     but is marked so that 'SIGHUP' is not sent to the job if the shell
+     receives a 'SIGHUP'.  If JOBSPEC is not present, and neither the
+     '-a' nor the '-r' option is supplied, the current job is used.  If
+     no JOBSPEC is supplied, the '-a' option means to remove or mark all
+     jobs; the '-r' option without a JOBSPEC argument restricts
+     operation to running jobs.
+
+'suspend'
+          suspend [-f]
+
+     Suspend the execution of this shell until it receives a 'SIGCONT'
+     signal.  A login shell, or a shell without job control enabled,
+     cannot be suspended; the '-f' option can be used to override this
+     and force the suspension.  The return status is 0 unless the shell
+     is a login shell or job control is not enabled and '-f' is not
+     supplied.
+
+   When job control is not active, the 'kill' and 'wait' builtins do not
+accept JOBSPEC arguments.  They must be supplied process IDs.

+
+7.3 Job Control Variables
+=========================
+
+'auto_resume'
+     This variable controls how the shell interacts with the user and
+     job control.  If this variable exists then single word simple
+     commands without redirections are treated as candidates for
+     resumption of an existing job.  There is no ambiguity allowed; if
+     there is more than one job beginning with the string typed, then
+     the most recently accessed job will be selected.  The name of a
+     stopped job, in this context, is the command line used to start it.
+     If this variable is set to the value 'exact', the string supplied
+     must match the name of a stopped job exactly; if set to
+     'substring', the string supplied needs to match a substring of the
+     name of a stopped job.  The 'substring' value provides
+     functionality analogous to the '%?' job ID (*note Job Control
+     Basics::).  If set to any other value, the supplied string must be
+     a prefix of a stopped job's name; this provides functionality
+     analogous to the '%' job ID.

+8 Command Line Editing
+**********************
+
+This chapter describes the basic features of the GNU command line
+editing interface.  Command line editing is provided by the Readline
+library, which is used by several different programs, including Bash.

+8.1 Introduction to Line Editing
+================================
+
+The following paragraphs describe the notation used to represent
+keystrokes.
+
+   The text 'C-k' is read as 'Control-K' and describes the character
+produced when the <k> key is pressed while the Control key is depressed.
+
+   The text 'M-k' is read as 'Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the <k>
+key is pressed.  The Meta key is labeled <ALT> on many keyboards.  On
+keyboards with two keys labeled <ALT> (usually to either side of the
+space bar), the <ALT> on the left side is generally set to work as a
+Meta key.  The <ALT> key on the right may also be configured to work as
+a Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+
+   If you do not have a Meta or <ALT> key, or another key working as a
+Meta key, the identical keystroke can be generated by typing <ESC>
+_first_, and then typing <k>.  Either process is known as "metafying"
+the <k> key.
+
+   The text 'M-C-k' is read as 'Meta-Control-k' and describes the
+character produced by "metafying" 'C-k'.
+
+   In addition, several keys have their own names.  Specifically, <DEL>,
+<ESC>, <LFD>, <SPC>, <RET>, and <TAB> all stand for themselves when seen
+in this text, or in an init file (*note Readline Init File::).  If your
+keyboard lacks a <LFD> key, typing <C-j> will produce the desired
+character.  The <RET> key may be labeled <Return> or <Enter> on some
+keyboards.

+8.2 Readline Interaction
+========================
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled.  The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line.  Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections.  Then, when you are satisfied with
+the line, you simply press <RET>.  You do not have to be at the end of
+the line to press <RET>; the entire line is accepted regardless of the
+location of the cursor within the line.

+
+8.2.1 Readline Bare Essentials
+------------------------------
+
+In order to enter characters into the line, simply type them.  The typed
+character appears where the cursor was, and then the cursor moves one
+space to the right.  If you mistype a character, you can use your erase
+character to back up and delete the mistyped character.
+
+   Sometimes you may mistype a character, and not notice the error until
+you have typed several other characters.  In that case, you can type
+'C-b' to move the cursor to the left, and then correct your mistake.
+Afterwards, you can move the cursor to the right with 'C-f'.
+
+   When you add text in the middle of a line, you will notice that
+characters to the right of the cursor are 'pushed over' to make room for
+the text that you have inserted.  Likewise, when you delete text behind
+the cursor, characters to the right of the cursor are 'pulled back' to
+fill in the blank space created by the removal of the text.  A list of
+the bare essentials for editing the text of an input line follows.
+
+'C-b'
+     Move back one character.
+'C-f'
+     Move forward one character.
+<DEL> or <Backspace>
+     Delete the character to the left of the cursor.
+'C-d'
+     Delete the character underneath the cursor.
+Printing characters
+     Insert the character into the line at the cursor.
+'C-_' or 'C-x C-u'
+     Undo the last editing command.  You can undo all the way back to an
+     empty line.
+
+(Depending on your configuration, the <Backspace> key might be set to
+delete the character to the left of the cursor and the <DEL> key set to
+delete the character underneath the cursor, like 'C-d', rather than the
+character to the left of the cursor.)

+
+8.2.2 Readline Movement Commands
+--------------------------------
+
+The above table describes the most basic keystrokes that you need in
+order to do editing of the input line.  For your convenience, many other
+commands have been added in addition to 'C-b', 'C-f', 'C-d', and <DEL>.
+Here are some commands for moving more rapidly about the line.
+
+'C-a'
+     Move to the start of the line.
+'C-e'
+     Move to the end of the line.
+'M-f'
+     Move forward a word, where a word is composed of letters and
+     digits.
+'M-b'
+     Move backward a word.
+'C-l'
+     Clear the screen, reprinting the current line at the top.
+
+   Notice how 'C-f' moves forward a character, while 'M-f' moves forward
+a word.  It is a loose convention that control keystrokes operate on
+characters while meta keystrokes operate on words.

+
+8.2.3 Readline Killing Commands
+-------------------------------
+
+"Killing" text means to delete the text from the line, but to save it
+away for later use, usually by "yanking" (re-inserting) it back into the
+line.  ('Cut' and 'paste' are more recent jargon for 'kill' and 'yank'.)
+
+   If the description for a command says that it 'kills' text, then you
+can be sure that you can get the text back in a different (or the same)
+place later.
+
+   When you use a kill command, the text is saved in a "kill-ring".  Any
+number of consecutive kills save all of the killed text together, so
+that when you yank it back, you get it all.  The kill ring is not line
+specific; the text that you killed on a previously typed line is
+available to be yanked back later, when you are typing another line.
+
+   Here is the list of commands for killing text.
+
+'C-k'
+     Kill the text from the current cursor position to the end of the
+     line.
+
+'M-d'
+     Kill from the cursor to the end of the current word, or, if between
+     words, to the end of the next word.  Word boundaries are the same
+     as those used by 'M-f'.
+
+'M-<DEL>'
+     Kill from the cursor to the start of the current word, or, if
+     between words, to the start of the previous word.  Word boundaries
+     are the same as those used by 'M-b'.
+
+'C-w'
+     Kill from the cursor to the previous whitespace.  This is different
+     than 'M-<DEL>' because the word boundaries differ.
+
+   Here is how to "yank" the text back into the line.  Yanking means to
+copy the most-recently-killed text from the kill buffer.
+
+'C-y'
+     Yank the most recently killed text back into the buffer at the
+     cursor.
+
+'M-y'
+     Rotate the kill-ring, and yank the new top.  You can only do this
+     if the prior command is 'C-y' or 'M-y'.
+
+
+File: bashref.info,  Node: Readline Arguments,  Next: Searching,  Prev: Readline Killing Commands,  Up: Readline Interaction
+
+8.2.4 Readline Arguments
+------------------------
+
+You can pass numeric arguments to Readline commands.  Sometimes the
+argument acts as a repeat count, other times it is the sign of the
+argument that is significant.  If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction.  For example, to kill text back to the
+start of the line, you might type 'M-- C-k'.
+
+   The general way to pass numeric arguments to a command is to type
+meta digits before the command.  If the first 'digit' typed is a minus
+sign ('-'), then the sign of the argument will be negative.  Once you
+have typed one meta digit to get the argument started, you can type the
+remainder of the digits, and then the command.  For example, to give the
+'C-d' command an argument of 10, you could type 'M-1 0 C-d', which will
+delete the next ten characters on the input line.
+
+
+File: bashref.info,  Node: Searching,  Prev: Readline Arguments,  Up: Readline Interaction
+
+8.2.5 Searching for Commands in the History
+-------------------------------------------
+
+Readline provides commands for searching through the command history
+(*note Bash History Facilities::) for lines containing a specified
+string.  There are two search modes: "incremental" and
+"non-incremental".
+
+   Incremental searches begin before the user has finished typing the
+search string.  As each character of the search string is typed,
+Readline displays the next entry from the history matching the string
+typed so far.  An incremental search requires only as many characters as
+needed to find the desired history entry.  To search backward in the
+history for a particular string, type 'C-r'.  Typing 'C-s' searches
+forward through the history.  The characters present in the value of the
+'isearch-terminators' variable are used to terminate an incremental
+search.  If that variable has not been assigned a value, the <ESC> and
+'C-J' characters will terminate an incremental search.  'C-g' will abort
+an incremental search and restore the original line.  When the search is
+terminated, the history entry containing the search string becomes the
+current line.
+
+   To find other matching entries in the history list, type 'C-r' or
+'C-s' as appropriate.  This will search backward or forward in the
+history for the next entry matching the search string typed so far.  Any
+other key sequence bound to a Readline command will terminate the search
+and execute that command.  For instance, a <RET> will terminate the
+search and accept the line, thereby executing the command from the
+history list.  A movement command will terminate the search, make the
+last line found the current line, and begin editing.
+
+   Readline remembers the last incremental search string.  If two 'C-r's
+are typed without any intervening characters defining a new search
+string, any remembered search string is used.
+
+   Non-incremental searches read the entire search string before
+starting to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.

+
+8.3 Readline Init File
+======================
+
+Although the Readline library comes with a set of Emacs-like keybindings
+installed by default, it is possible to use a different set of
+keybindings.  Any user can customize programs that use Readline by
+putting commands in an "inputrc" file, conventionally in their home
+directory.  The name of this file is taken from the value of the shell
+variable 'INPUTRC'.  If that variable is unset, the default is
+'~/.inputrc'.  If that file does not exist or cannot be read, the
+ultimate default is '/etc/inputrc'.  The 'bind' builtin command can also
+be used to set Readline keybindings and variables.  *Note Bash
+Builtins::.
+
+   When a program which uses the Readline library starts up, the init
+file is read, and the key bindings are set.
+
+   In addition, the 'C-x C-r' command re-reads this init file, thus
+incorporating any changes that you might have made to it.

+
+
+File: bashref.info,  Node: Readline Init File Syntax,  Next: Conditional Init Constructs,  Up: Readline Init File
+
+8.3.1 Readline Init File Syntax
+-------------------------------
+
+There are only a few basic constructs allowed in the Readline init file.
+Blank lines are ignored.  Lines beginning with a '#' are comments.
+Lines beginning with a '$' indicate conditional constructs (*note
+Conditional Init Constructs::).  Other lines denote variable settings
+and key bindings.
+
+Variable Settings
+     You can modify the run-time behavior of Readline by altering the
+     values of variables in Readline using the 'set' command within the
+     init file.  The syntax is simple:
+
+          set VARIABLE VALUE
+
+     Here, for example, is how to change from the default Emacs-like key
+     binding to use 'vi' line editing commands:
+
+          set editing-mode vi
+
+     Variable names and values, where appropriate, are recognized
+     without regard to case.  Unrecognized variable names are ignored.
+
+     Boolean variables (those that can be set to on or off) are set to
+     on if the value is null or empty, ON (case-insensitive), or 1.  Any
+     other value results in the variable being set to off.
+
+     The 'bind -V' command lists the current Readline variable names and
+     values.  *Note Bash Builtins::.
+
+     A great deal of run-time behavior is changeable with the following
+     variables.
+
+     'active-region-start-color'
+          A string variable that controls the text color and background
+          when displaying the text in the active region (see the
+          description of 'enable-active-region' below).  This string
+          must not take up any physical character positions on the
+          display, so it should consist only of terminal escape
+          sequences.  It is output to the terminal before displaying the
+          text in the active region.  This variable is reset to the
+          default value whenever the terminal type changes.  The default
+          value is the string that puts the terminal in standout mode,
+          as obtained from the terminal's terminfo description.  A
+          sample value might be '\e[01;33m'.
+
+     'active-region-end-color'
+          A string variable that "undoes" the effects of
+          'active-region-start-color' and restores "normal" terminal
+          display appearance after displaying text in the active region.
+          This string must not take up any physical character positions
+          on the display, so it should consist only of terminal escape
+          sequences.  It is output to the terminal after displaying the
+          text in the active region.  This variable is reset to the
+          default value whenever the terminal type changes.  The default
+          value is the string that restores the terminal from standout
+          mode, as obtained from the terminal's terminfo description.  A
+          sample value might be '\e[0m'.
+
+     'bell-style'
+          Controls what happens when Readline wants to ring the terminal
+          bell.  If set to 'none', Readline never rings the bell.  If
+          set to 'visible', Readline uses a visible bell if one is
+          available.  If set to 'audible' (the default), Readline
+          attempts to ring the terminal's bell.
+
+     'bind-tty-special-chars'
+          If set to 'on' (the default), Readline attempts to bind the
+          control characters treated specially by the kernel's terminal
+          driver to their Readline equivalents.
+
+     'blink-matching-paren'
+          If set to 'on', Readline attempts to briefly move the cursor
+          to an opening parenthesis when a closing parenthesis is
+          inserted.  The default is 'off'.
+
+     'colored-completion-prefix'
+          If set to 'on', when listing completions, Readline displays
+          the common prefix of the set of possible completions using a
+          different color.  The color definitions are taken from the
+          value of the 'LS_COLORS' environment variable.  If there is a
+          color definition in 'LS_COLORS' for the custom suffix
+          'readline-colored-completion-prefix', Readline uses this color
+          for the common prefix instead of its default.  The default is
+          'off'.
+
+     'colored-stats'
+          If set to 'on', Readline displays possible completions using
+          different colors to indicate their file type.  The color
+          definitions are taken from the value of the 'LS_COLORS'
+          environment variable.  The default is 'off'.
+
+     'comment-begin'
+          The string to insert at the beginning of the line when the
+          'insert-comment' command is executed.  The default value is
+          '"#"'.
+
+     'completion-display-width'
+          The number of screen columns used to display possible matches
+          when performing completion.  The value is ignored if it is
+          less than 0 or greater than the terminal screen width.  A
+          value of 0 will cause matches to be displayed one per line.
+          The default value is -1.
+
+     'completion-ignore-case'
+          If set to 'on', Readline performs filename matching and
+          completion in a case-insensitive fashion.  The default value
+          is 'off'.
+
+     'completion-map-case'
+          If set to 'on', and COMPLETION-IGNORE-CASE is enabled,
+          Readline treats hyphens ('-') and underscores ('_') as
+          equivalent when performing case-insensitive filename matching
+          and completion.  The default value is 'off'.
+
+     'completion-prefix-display-length'
+          The length in characters of the common prefix of a list of
+          possible completions that is displayed without modification.
+          When set to a value greater than zero, common prefixes longer
+          than this value are replaced with an ellipsis when displaying
+          possible completions.
+
+     'completion-query-items'
+          The number of possible completions that determines when the
+          user is asked whether the list of possibilities should be
+          displayed.  If the number of possible completions is greater
+          than or equal to this value, Readline will ask whether or not
+          the user wishes to view them; otherwise, they are simply
+          listed.  This variable must be set to an integer value greater
+          than or equal to zero.  A zero value means Readline should
+          never ask; negative values are treated as zero.  The default
+          limit is '100'.
+
+     'convert-meta'
+          If set to 'on', Readline will convert characters with the
+          eighth bit set to an ASCII key sequence by stripping the
+          eighth bit and prefixing an <ESC> character, converting them
+          to a meta-prefixed key sequence.  The default value is 'on',
+          but will be set to 'off' if the locale is one that contains
+          eight-bit characters.  This variable is dependent on the
+          'LC_CTYPE' locale category, and may change if the locale is
+          changed.
+
+     'disable-completion'
+          If set to 'On', Readline will inhibit word completion.
+          Completion characters will be inserted into the line as if
+          they had been mapped to 'self-insert'.  The default is 'off'.
+
+     'echo-control-characters'
+          When set to 'on', on operating systems that indicate they
+          support it, Readline echoes a character corresponding to a
+          signal generated from the keyboard.  The default is 'on'.
+
+     'editing-mode'
+          The 'editing-mode' variable controls which default set of key
+          bindings is used.  By default, Readline starts up in Emacs
+          editing mode, where the keystrokes are most similar to Emacs.
+          This variable can be set to either 'emacs' or 'vi'.
+
+     'emacs-mode-string'
+          If the SHOW-MODE-IN-PROMPT variable is enabled, this string is
+          displayed immediately before the last line of the primary
+          prompt when emacs editing mode is active.  The value is
+          expanded like a key binding, so the standard set of meta- and
+          control prefixes and backslash escape sequences is available.
+          Use the '\1' and '\2' escapes to begin and end sequences of
+          non-printing characters, which can be used to embed a terminal
+          control sequence into the mode string.  The default is '@'.
+
+     'enable-active-region'
+          The "point" is the current cursor position, and "mark" refers
+          to a saved cursor position (*note Commands For Moving::).  The
+          text between the point and mark is referred to as the
+          "region".  When this variable is set to 'On', Readline allows
+          certain commands to designate the region as "active".  When
+          the region is active, Readline highlights the text in the
+          region using the value of the 'active-region-start-color',
+          which defaults to the string that enables the terminal's
+          standout mode.  The active region shows the text inserted by
+          bracketed-paste and any matching text found by incremental and
+          non-incremental history searches.  The default is 'On'.
+
+     'enable-bracketed-paste'
+          When set to 'On', Readline configures the terminal to insert
+          each paste into the editing buffer as a single string of
+          characters, instead of treating each character as if it had
+          been read from the keyboard.  This is called putting the
+          terminal into "bracketed paste mode"; it prevents Readline
+          from executing any editing commands bound to key sequences
+          appearing in the pasted text.  The default is 'On'.
+
+     'enable-keypad'
+          When set to 'on', Readline will try to enable the application
+          keypad when it is called.  Some systems need this to enable
+          the arrow keys.  The default is 'off'.
+
+     'enable-meta-key'
+          When set to 'on', Readline will try to enable any meta
+          modifier key the terminal claims to support when it is called.
+          On many terminals, the meta key is used to send eight-bit
+          characters.  The default is 'on'.
+
+     'expand-tilde'
+          If set to 'on', tilde expansion is performed when Readline
+          attempts word completion.  The default is 'off'.
+
+     'history-preserve-point'
+          If set to 'on', the history code attempts to place the point
+          (the current cursor position) at the same location on each
+          history line retrieved with 'previous-history' or
+          'next-history'.  The default is 'off'.
+
+     'history-size'
+          Set the maximum number of history entries saved in the history
+          list.  If set to zero, any existing history entries are
+          deleted and no new entries are saved.  If set to a value less
+          than zero, the number of history entries is not limited.  By
+          default, the number of history entries is not limited.  If an
+          attempt is made to set HISTORY-SIZE to a non-numeric value,
+          the maximum number of history entries will be set to 500.
+
+     'horizontal-scroll-mode'
+          This variable can be set to either 'on' or 'off'.  Setting it
+          to 'on' means that the text of the lines being edited will
+          scroll horizontally on a single screen line when they are
+          longer than the width of the screen, instead of wrapping onto
+          a new screen line.  This variable is automatically set to 'on'
+          for terminals of height 1.  By default, this variable is set
+          to 'off'.
+
+     'input-meta'
+          If set to 'on', Readline will enable eight-bit input (it will
+          not clear the eighth bit in the characters it reads),
+          regardless of what the terminal claims it can support.  The
+          default value is 'off', but Readline will set it to 'on' if
+          the locale contains eight-bit characters.  The name
+          'meta-flag' is a synonym for this variable.  This variable is
+          dependent on the 'LC_CTYPE' locale category, and may change if
+          the locale is changed.
+
+     'isearch-terminators'
+          The string of characters that should terminate an incremental
+          search without subsequently executing the character as a
+          command (*note Searching::).  If this variable has not been
+          given a value, the characters <ESC> and 'C-J' will terminate
+          an incremental search.
+
+     'keymap'
+          Sets Readline's idea of the current keymap for key binding
+          commands.  Built-in 'keymap' names are 'emacs',
+          'emacs-standard', 'emacs-meta', 'emacs-ctlx', 'vi', 'vi-move',
+          'vi-command', and 'vi-insert'.  'vi' is equivalent to
+          'vi-command' ('vi-move' is also a synonym); 'emacs' is
+          equivalent to 'emacs-standard'.  Applications may add
+          additional names.  The default value is 'emacs'.  The value of
+          the 'editing-mode' variable also affects the default keymap.
+
+     'keyseq-timeout'
+          Specifies the duration Readline will wait for a character when
+          reading an ambiguous key sequence (one that can form a
+          complete key sequence using the input read so far, or can take
+          additional input to complete a longer key sequence).  If no
+          input is received within the timeout, Readline will use the
+          shorter but complete key sequence.  Readline uses this value
+          to determine whether or not input is available on the current
+          input source ('rl_instream' by default).  The value is
+          specified in milliseconds, so a value of 1000 means that
+          Readline will wait one second for additional input.  If this
+          variable is set to a value less than or equal to zero, or to a
+          non-numeric value, Readline will wait until another key is
+          pressed to decide which key sequence to complete.  The default
+          value is '500'.
+
+     'mark-directories'
+          If set to 'on', completed directory names have a slash
+          appended.  The default is 'on'.
+
+     'mark-modified-lines'
+          This variable, when set to 'on', causes Readline to display an
+          asterisk ('*') at the start of history lines which have been
+          modified.  This variable is 'off' by default.
+
+     'mark-symlinked-directories'
+          If set to 'on', completed names which are symbolic links to
+          directories have a slash appended (subject to the value of
+          'mark-directories').  The default is 'off'.
+
+     'match-hidden-files'
+          This variable, when set to 'on', causes Readline to match
+          files whose names begin with a '.' (hidden files) when
+          performing filename completion.  If set to 'off', the leading
+          '.' must be supplied by the user in the filename to be
+          completed.  This variable is 'on' by default.
+
+     'menu-complete-display-prefix'
+          If set to 'on', menu completion displays the common prefix of
+          the list of possible completions (which may be empty) before
+          cycling through the list.  The default is 'off'.
+
+     'output-meta'
+          If set to 'on', Readline will display characters with the
+          eighth bit set directly rather than as a meta-prefixed escape
+          sequence.  The default is 'off', but Readline will set it to
+          'on' if the locale contains eight-bit characters.  This
+          variable is dependent on the 'LC_CTYPE' locale category, and
+          may change if the locale is changed.
+
+     'page-completions'
+          If set to 'on', Readline uses an internal 'more'-like pager to
+          display a screenful of possible completions at a time.  This
+          variable is 'on' by default.
+
+     'print-completions-horizontally'
+          If set to 'on', Readline will display completions with matches
+          sorted horizontally in alphabetical order, rather than down
+          the screen.  The default is 'off'.
+
+     'revert-all-at-newline'
+          If set to 'on', Readline will undo all changes to history
+          lines before returning when 'accept-line' is executed.  By
+          default, history lines may be modified and retain individual
+          undo lists across calls to 'readline()'.  The default is
+          'off'.
+
+     'show-all-if-ambiguous'
+          This alters the default behavior of the completion functions.
+          If set to 'on', words which have more than one possible
+          completion cause the matches to be listed immediately instead
+          of ringing the bell.  The default value is 'off'.
+
+     'show-all-if-unmodified'
+          This alters the default behavior of the completion functions
+          in a fashion similar to SHOW-ALL-IF-AMBIGUOUS.  If set to
+          'on', words which have more than one possible completion
+          without any possible partial completion (the possible
+          completions don't share a common prefix) cause the matches to
+          be listed immediately instead of ringing the bell.  The
+          default value is 'off'.
+
+     'show-mode-in-prompt'
+          If set to 'on', add a string to the beginning of the prompt
+          indicating the editing mode: emacs, vi command, or vi
+          insertion.  The mode strings are user-settable (e.g.,
+          EMACS-MODE-STRING).  The default value is 'off'.
+
+     'skip-completed-text'
+          If set to 'on', this alters the default completion behavior
+          when inserting a single match into the line.  It's only active
+          when performing completion in the middle of a word.  If
+          enabled, Readline does not insert characters from the
+          completion that match characters after point in the word being
+          completed, so portions of the word following the cursor are
+          not duplicated.  For instance, if this is enabled, attempting
+          completion when the cursor is after the 'e' in 'Makefile' will
+          result in 'Makefile' rather than 'Makefilefile', assuming
+          there is a single possible completion.  The default value is
+          'off'.
+
+     'vi-cmd-mode-string'
+          If the SHOW-MODE-IN-PROMPT variable is enabled, this string is
+          displayed immediately before the last line of the primary
+          prompt when vi editing mode is active and in command mode.
+          The value is expanded like a key binding, so the standard set
+          of meta- and control prefixes and backslash escape sequences
+          is available.  Use the '\1' and '\2' escapes to begin and end
+          sequences of non-printing characters, which can be used to
+          embed a terminal control sequence into the mode string.  The
+          default is '(cmd)'.
+
+     'vi-ins-mode-string'
+          If the SHOW-MODE-IN-PROMPT variable is enabled, this string is
+          displayed immediately before the last line of the primary
+          prompt when vi editing mode is active and in insertion mode.
+          The value is expanded like a key binding, so the standard set
+          of meta- and control prefixes and backslash escape sequences
+          is available.  Use the '\1' and '\2' escapes to begin and end
+          sequences of non-printing characters, which can be used to
+          embed a terminal control sequence into the mode string.  The
+          default is '(ins)'.
+
+     'visible-stats'
+          If set to 'on', a character denoting a file's type is appended
+          to the filename when listing possible completions.  The
+          default is 'off'.
+
+Key Bindings
+     The syntax for controlling key bindings in the init file is simple.
+     First you need to find the name of the command that you want to
+     change.  The following sections contain tables of the command name,
+     the default keybinding, if any, and a short description of what the
+     command does.
+
+     Once you know the name of the command, simply place on a line in
+     the init file the name of the key you wish to bind the command to,
+     a colon, and then the name of the command.  There can be no space
+     between the key name and the colon - that will be interpreted as
+     part of the key name.  The name of the key can be expressed in
+     different ways, depending on what you find most comfortable.
+
+     In addition to command names, Readline allows keys to be bound to a
+     string that is inserted when the key is pressed (a MACRO).
+
+     The 'bind -p' command displays Readline function names and bindings
+     in a format that can be put directly into an initialization file.
+     *Note Bash Builtins::.
+
+     KEYNAME: FUNCTION-NAME or MACRO
+          KEYNAME is the name of a key spelled out in English.  For
+          example:
+               Control-u: universal-argument
+               Meta-Rubout: backward-kill-word
+               Control-o: "> output"
+
+          In the example above, 'C-u' is bound to the function
+          'universal-argument', 'M-DEL' is bound to the function
+          'backward-kill-word', and 'C-o' is bound to run the macro
+          expressed on the right hand side (that is, to insert the text
+          '> output' into the line).
+
+          A number of symbolic character names are recognized while
+          processing this key binding syntax: DEL, ESC, ESCAPE, LFD,
+          NEWLINE, RET, RETURN, RUBOUT, SPACE, SPC, and TAB.
+
+     "KEYSEQ": FUNCTION-NAME or MACRO
+          KEYSEQ differs from KEYNAME above in that strings denoting an
+          entire key sequence can be specified, by placing the key
+          sequence in double quotes.  Some GNU Emacs style key escapes
+          can be used, as in the following example, but the special
+          character names are not recognized.
+
+               "\C-u": universal-argument
+               "\C-x\C-r": re-read-init-file
+               "\e[11~": "Function Key 1"
+
+          In the above example, 'C-u' is again bound to the function
+          'universal-argument' (just as it was in the first example),
+          ''C-x' 'C-r'' is bound to the function 're-read-init-file',
+          and '<ESC> <[> <1> <1> <~>' is bound to insert the text
+          'Function Key 1'.
+
+     The following GNU Emacs style escape sequences are available when
+     specifying key sequences:
+
+     '\C-'
+          control prefix
+     '\M-'
+          meta prefix
+     '\e'
+          an escape character
+     '\\'
+          backslash
+     '\"'
+          <">, a double quotation mark
+     '\''
+          <'>, a single quote or apostrophe
+
+     In addition to the GNU Emacs style escape sequences, a second set
+     of backslash escapes is available:
+
+     '\a'
+          alert (bell)
+     '\b'
+          backspace
+     '\d'
+          delete
+     '\f'
+          form feed
+     '\n'
+          newline
+     '\r'
+          carriage return
+     '\t'
+          horizontal tab
+     '\v'
+          vertical tab
+     '\NNN'
+          the eight-bit character whose value is the octal value NNN
+          (one to three digits)
+     '\xHH'
+          the eight-bit character whose value is the hexadecimal value
+          HH (one or two hex digits)
+
+     When entering the text of a macro, single or double quotes must be
+     used to indicate a macro definition.  Unquoted text is assumed to
+     be a function name.  In the macro body, the backslash escapes
+     described above are expanded.  Backslash will quote any other
+     character in the macro text, including '"' and '''.  For example,
+     the following binding will make ''C-x' \' insert a single '\' into
+     the line:
+          "\C-x\\": "\\"

+
+8.3.2 Conditional Init Constructs
+---------------------------------
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key bindings and
+variable settings to be performed as the result of tests.  There are
+four parser directives used.
+
+'$if'
+     The '$if' construct allows bindings to be made based on the editing
+     mode, the terminal being used, or the application using Readline.
+     The text of the test, after any comparison operator, extends to the
+     end of the line; unless otherwise noted, no characters are required
+     to isolate it.
+
+     'mode'
+          The 'mode=' form of the '$if' directive is used to test
+          whether Readline is in 'emacs' or 'vi' mode.  This may be used
+          in conjunction with the 'set keymap' command, for instance, to
+          set bindings in the 'emacs-standard' and 'emacs-ctlx' keymaps
+          only if Readline is starting out in 'emacs' mode.
+
+     'term'
+          The 'term=' form may be used to include terminal-specific key
+          bindings, perhaps to bind the key sequences output by the
+          terminal's function keys.  The word on the right side of the
+          '=' is tested against both the full name of the terminal and
+          the portion of the terminal name before the first '-'.  This
+          allows 'sun' to match both 'sun' and 'sun-cmd', for instance.
+
+     'version'
+          The 'version' test may be used to perform comparisons against
+          specific Readline versions.  The 'version' expands to the
+          current Readline version.  The set of comparison operators
+          includes '=' (and '=='), '!=', '<=', '>=', '<', and '>'.  The
+          version number supplied on the right side of the operator
+          consists of a major version number, an optional decimal point,
+          and an optional minor version (e.g., '7.1').  If the minor
+          version is omitted, it is assumed to be '0'.  The operator may
+          be separated from the string 'version' and from the version
+          number argument by whitespace.  The following example sets a
+          variable if the Readline version being used is 7.0 or newer:
+               $if version >= 7.0
+               set show-mode-in-prompt on
+               $endif
+
+     'application'
+          The APPLICATION construct is used to include
+          application-specific settings.  Each program using the
+          Readline library sets the APPLICATION NAME, and you can test
+          for a particular value.  This could be used to bind key
+          sequences to functions useful for a specific program.  For
+          instance, the following command adds a key sequence that
+          quotes the current or previous word in Bash:
+               $if Bash
+               # Quote the current or previous word
+               "\C-xq": "\eb\"\ef\""
+               $endif
+
+     'variable'
+          The VARIABLE construct provides simple equality tests for
+          Readline variables and values.  The permitted comparison
+          operators are '=', '==', and '!='.  The variable name must be
+          separated from the comparison operator by whitespace; the
+          operator may be separated from the value on the right hand
+          side by whitespace.  Both string and boolean variables may be
+          tested.  Boolean variables must be tested against the values
+          ON and OFF.  The following example is equivalent to the
+          'mode=emacs' test described above:
+               $if editing-mode == emacs
+               set show-mode-in-prompt on
+               $endif
+
+'$endif'
+     This command, as seen in the previous example, terminates an '$if'
+     command.
+
+'$else'
+     Commands in this branch of the '$if' directive are executed if the
+     test fails.
+
+'$include'
+     This directive takes a single filename as an argument and reads
+     commands and bindings from that file.  For example, the following
+     directive reads from '/etc/inputrc':
+          $include /etc/inputrc

+8.4 Bindable Readline Commands
+==============================
+
+* Menu:
+
+* Commands For Moving::		Moving about the line.
+* Commands For History::	Getting at previous lines.
+* Commands For Text::		Commands for changing text.
+* Commands For Killing::	Commands for killing and yanking.
+* Numeric Arguments::		Specifying numeric arguments, repeat counts.
+* Commands For Completion::	Getting Readline to do the typing for you.
+* Keyboard Macros::		Saving and re-executing typed characters
+* Miscellaneous Commands::	Other miscellaneous commands.
+
+This section describes Readline commands that may be bound to key
+sequences.  You can list your key bindings by executing 'bind -P' or,
+for a more terse format, suitable for an INPUTRC file, 'bind -p'.
+(*Note Bash Builtins::.)  Command names without an accompanying key
+sequence are unbound by default.
+
+   In the following descriptions, "point" refers to the current cursor
+position, and "mark" refers to a cursor position saved by the 'set-mark'
+command.  The text between the point and mark is referred to as the
+"region".

+
+
+File: bashref.info,  Node: Commands For History,  Next: Commands For Text,  Prev: Commands For Moving,  Up: Bindable Readline Commands
+
+8.4.2 Commands For Manipulating The History
+-------------------------------------------
+
+'accept-line (Newline or Return)'
+     Accept the line regardless of where the cursor is.  If this line is
+     non-empty, add it to the history list according to the setting of
+     the 'HISTCONTROL' and 'HISTIGNORE' variables.  If this line is a
+     modified history line, then restore the history line to its
+     original state.
+
+'previous-history (C-p)'
+     Move 'back' through the history list, fetching the previous
+     command.
+
+'next-history (C-n)'
+     Move 'forward' through the history list, fetching the next command.
+
+'beginning-of-history (M-<)'
+     Move to the first line in the history.
+
+'end-of-history (M->)'
+     Move to the end of the input history, i.e., the line currently
+     being entered.
+
+'reverse-search-history (C-r)'
+     Search backward starting at the current line and moving 'up'
+     through the history as necessary.  This is an incremental search.
+     This command sets the region to the matched text and activates the
+     mark.
+
+'forward-search-history (C-s)'
+     Search forward starting at the current line and moving 'down'
+     through the history as necessary.  This is an incremental search.
+     This command sets the region to the matched text and activates the
+     mark.
+
+'non-incremental-reverse-search-history (M-p)'
+     Search backward starting at the current line and moving 'up'
+     through the history as necessary using a non-incremental search for
+     a string supplied by the user.  The search string may match
+     anywhere in a history line.
+
+'non-incremental-forward-search-history (M-n)'
+     Search forward starting at the current line and moving 'down'
+     through the history as necessary using a non-incremental search for
+     a string supplied by the user.  The search string may match
+     anywhere in a history line.
+
+'history-search-forward ()'
+     Search forward through the history for the string of characters
+     between the start of the current line and the point.  The search
+     string must match at the beginning of a history line.  This is a
+     non-incremental search.  By default, this command is unbound.
+
+'history-search-backward ()'
+     Search backward through the history for the string of characters
+     between the start of the current line and the point.  The search
+     string must match at the beginning of a history line.  This is a
+     non-incremental search.  By default, this command is unbound.
+
+'history-substring-search-forward ()'
+     Search forward through the history for the string of characters
+     between the start of the current line and the point.  The search
+     string may match anywhere in a history line.  This is a
+     non-incremental search.  By default, this command is unbound.
+
+'history-substring-search-backward ()'
+     Search backward through the history for the string of characters
+     between the start of the current line and the point.  The search
+     string may match anywhere in a history line.  This is a
+     non-incremental search.  By default, this command is unbound.
+
+'yank-nth-arg (M-C-y)'
+     Insert the first argument to the previous command (usually the
+     second word on the previous line) at point.  With an argument N,
+     insert the Nth word from the previous command (the words in the
+     previous command begin with word 0).  A negative argument inserts
+     the Nth word from the end of the previous command.  Once the
+     argument N is computed, the argument is extracted as if the '!N'
+     history expansion had been specified.
+
+'yank-last-arg (M-. or M-_)'
+     Insert last argument to the previous command (the last word of the
+     previous history entry).  With a numeric argument, behave exactly
+     like 'yank-nth-arg'.  Successive calls to 'yank-last-arg' move back
+     through the history list, inserting the last word (or the word
+     specified by the argument to the first call) of each line in turn.
+     Any numeric argument supplied to these successive calls determines
+     the direction to move through the history.  A negative argument
+     switches the direction through the history (back or forward).  The
+     history expansion facilities are used to extract the last argument,
+     as if the '!$' history expansion had been specified.
+
+'operate-and-get-next (C-o)'
+     Accept the current line for return to the calling application as if
+     a newline had been entered, and fetch the next line relative to the
+     current line from the history for editing.  A numeric argument, if
+     supplied, specifies the history entry to use instead of the current
+     line.
+
+'fetch-history ()'
+     With a numeric argument, fetch that entry from the history list and
+     make it the current line.  Without an argument, move back to the
+     first entry in the history list.

+
+8.4.3 Commands For Changing Text
+--------------------------------
+
+'end-of-file (usually C-d)'
+     The character indicating end-of-file as set, for example, by
+     'stty'.  If this character is read when there are no characters on
+     the line, and point is at the beginning of the line, Readline
+     interprets it as the end of input and returns EOF.
+
+'delete-char (C-d)'
+     Delete the character at point.  If this function is bound to the
+     same character as the tty EOF character, as 'C-d' commonly is, see
+     above for the effects.
+
+'backward-delete-char (Rubout)'
+     Delete the character behind the cursor.  A numeric argument means
+     to kill the characters instead of deleting them.
+
+'forward-backward-delete-char ()'
+     Delete the character under the cursor, unless the cursor is at the
+     end of the line, in which case the character behind the cursor is
+     deleted.  By default, this is not bound to a key.
+
+'quoted-insert (C-q or C-v)'
+     Add the next character typed to the line verbatim.  This is how to
+     insert key sequences like 'C-q', for example.
+
+'self-insert (a, b, A, 1, !, ...)'
+     Insert yourself.
+
+'bracketed-paste-begin ()'
+     This function is intended to be bound to the "bracketed paste"
+     escape sequence sent by some terminals, and such a binding is
+     assigned by default.  It allows Readline to insert the pasted text
+     as a single unit without treating each character as if it had been
+     read from the keyboard.  The characters are inserted as if each one
+     was bound to 'self-insert' instead of executing any editing
+     commands.
+
+     Bracketed paste sets the region (the characters between point and
+     the mark) to the inserted text.  It uses the concept of an _active
+     mark_: when the mark is active, Readline redisplay uses the
+     terminal's standout mode to denote the region.
+
+'transpose-chars (C-t)'
+     Drag the character before the cursor forward over the character at
+     the cursor, moving the cursor forward as well.  If the insertion
+     point is at the end of the line, then this transposes the last two
+     characters of the line.  Negative arguments have no effect.
+
+'transpose-words (M-t)'
+     Drag the word before point past the word after point, moving point
+     past that word as well.  If the insertion point is at the end of
+     the line, this transposes the last two words on the line.
+
+'upcase-word (M-u)'
+     Uppercase the current (or following) word.  With a negative
+     argument, uppercase the previous word, but do not move the cursor.
+
+'downcase-word (M-l)'
+     Lowercase the current (or following) word.  With a negative
+     argument, lowercase the previous word, but do not move the cursor.
+
+'capitalize-word (M-c)'
+     Capitalize the current (or following) word.  With a negative
+     argument, capitalize the previous word, but do not move the cursor.
+
+'overwrite-mode ()'
+     Toggle overwrite mode.  With an explicit positive numeric argument,
+     switches to overwrite mode.  With an explicit non-positive numeric
+     argument, switches to insert mode.  This command affects only
+     'emacs' mode; 'vi' mode does overwrite differently.  Each call to
+     'readline()' starts in insert mode.
+
+     In overwrite mode, characters bound to 'self-insert' replace the
+     text at point rather than pushing the text to the right.
+     Characters bound to 'backward-delete-char' replace the character
+     before point with a space.
+
+     By default, this command is unbound.

+
+8.4.4 Killing And Yanking
+-------------------------
+
+'kill-line (C-k)'
+     Kill the text from point to the end of the line.  With a negative
+     numeric argument, kill backward from the cursor to the beginning of
+     the current line.
+
+'backward-kill-line (C-x Rubout)'
+     Kill backward from the cursor to the beginning of the current line.
+     With a negative numeric argument, kill forward from the cursor to
+     the end of the current line.
+
+'unix-line-discard (C-u)'
+     Kill backward from the cursor to the beginning of the current line.
+
+'kill-whole-line ()'
+     Kill all characters on the current line, no matter where point is.
+     By default, this is unbound.
+
+'kill-word (M-d)'
+     Kill from point to the end of the current word, or if between
+     words, to the end of the next word.  Word boundaries are the same
+     as 'forward-word'.
+
+'backward-kill-word (M-<DEL>)'
+     Kill the word behind point.  Word boundaries are the same as
+     'backward-word'.
+
+'shell-kill-word (M-C-d)'
+     Kill from point to the end of the current word, or if between
+     words, to the end of the next word.  Word boundaries are the same
+     as 'shell-forward-word'.
+
+'shell-backward-kill-word ()'
+     Kill the word behind point.  Word boundaries are the same as
+     'shell-backward-word'.
+
+'shell-transpose-words (M-C-t)'
+     Drag the word before point past the word after point, moving point
+     past that word as well.  If the insertion point is at the end of
+     the line, this transposes the last two words on the line.  Word
+     boundaries are the same as 'shell-forward-word' and
+     'shell-backward-word'.
+
+'unix-word-rubout (C-w)'
+     Kill the word behind point, using white space as a word boundary.
+     The killed text is saved on the kill-ring.
+
+'unix-filename-rubout ()'
+     Kill the word behind point, using white space and the slash
+     character as the word boundaries.  The killed text is saved on the
+     kill-ring.
+
+'delete-horizontal-space ()'
+     Delete all spaces and tabs around point.  By default, this is
+     unbound.
+
+'kill-region ()'
+     Kill the text in the current region.  By default, this command is
+     unbound.
+
+'copy-region-as-kill ()'
+     Copy the text in the region to the kill buffer, so it can be yanked
+     right away.  By default, this command is unbound.
+
+'copy-backward-word ()'
+     Copy the word before point to the kill buffer.  The word boundaries
+     are the same as 'backward-word'.  By default, this command is
+     unbound.
+
+'copy-forward-word ()'
+     Copy the word following point to the kill buffer.  The word
+     boundaries are the same as 'forward-word'.  By default, this
+     command is unbound.
+
+'yank (C-y)'
+     Yank the top of the kill ring into the buffer at point.
+
+'yank-pop (M-y)'
+     Rotate the kill-ring, and yank the new top.  You can only do this
+     if the prior command is 'yank' or 'yank-pop'.
+
+

+
+8.4.5 Specifying Numeric Arguments
+----------------------------------
+
+'digit-argument (M-0, M-1, ... M--)'
+     Add this digit to the argument already accumulating, or start a new
+     argument.  'M--' starts a negative argument.
+
+'universal-argument ()'
+     This is another way to specify an argument.  If this command is
+     followed by one or more digits, optionally with a leading minus
+     sign, those digits define the argument.  If the command is followed
+     by digits, executing 'universal-argument' again ends the numeric
+     argument, but is otherwise ignored.  As a special case, if this
+     command is immediately followed by a character that is neither a
+     digit nor minus sign, the argument count for the next command is
+     multiplied by four.  The argument count is initially one, so
+     executing this function the first time makes the argument count
+     four, a second time makes the argument count sixteen, and so on.
+     By default, this is not bound to a key.

+
+8.4.6 Letting Readline Type For You
+-----------------------------------
+
+'complete (<TAB>)'
+     Attempt to perform completion on the text before point.  The actual
+     completion performed is application-specific.  Bash attempts
+     completion treating the text as a variable (if the text begins with
+     '$'), username (if the text begins with '~'), hostname (if the text
+     begins with '@'), or command (including aliases and functions) in
+     turn.  If none of these produces a match, filename completion is
+     attempted.
+
+'possible-completions (M-?)'
+     List the possible completions of the text before point.  When
+     displaying completions, Readline sets the number of columns used
+     for display to the value of 'completion-display-width', the value
+     of the environment variable 'COLUMNS', or the screen width, in that
+     order.
+
+'insert-completions (M-*)'
+     Insert all completions of the text before point that would have
+     been generated by 'possible-completions'.
+
+'menu-complete ()'
+     Similar to 'complete', but replaces the word to be completed with a
+     single match from the list of possible completions.  Repeated
+     execution of 'menu-complete' steps through the list of possible
+     completions, inserting each match in turn.  At the end of the list
+     of completions, the bell is rung (subject to the setting of
+     'bell-style') and the original text is restored.  An argument of N
+     moves N positions forward in the list of matches; a negative
+     argument may be used to move backward through the list.  This
+     command is intended to be bound to <TAB>, but is unbound by
+     default.
+
+'menu-complete-backward ()'
+     Identical to 'menu-complete', but moves backward through the list
+     of possible completions, as if 'menu-complete' had been given a
+     negative argument.
+
+'delete-char-or-list ()'
+     Deletes the character under the cursor if not at the beginning or
+     end of the line (like 'delete-char').  If at the end of the line,
+     behaves identically to 'possible-completions'.  This command is
+     unbound by default.
+
+'complete-filename (M-/)'
+     Attempt filename completion on the text before point.
+
+'possible-filename-completions (C-x /)'
+     List the possible completions of the text before point, treating it
+     as a filename.
+
+'complete-username (M-~)'
+     Attempt completion on the text before point, treating it as a
+     username.
+
+'possible-username-completions (C-x ~)'
+     List the possible completions of the text before point, treating it
+     as a username.
+
+'complete-variable (M-$)'
+     Attempt completion on the text before point, treating it as a shell
+     variable.
+
+'possible-variable-completions (C-x $)'
+     List the possible completions of the text before point, treating it
+     as a shell variable.
+
+'complete-hostname (M-@)'
+     Attempt completion on the text before point, treating it as a
+     hostname.
+
+'possible-hostname-completions (C-x @)'
+     List the possible completions of the text before point, treating it
+     as a hostname.
+
+'complete-command (M-!)'
+     Attempt completion on the text before point, treating it as a
+     command name.  Command completion attempts to match the text
+     against aliases, reserved words, shell functions, shell builtins,
+     and finally executable filenames, in that order.
+
+'possible-command-completions (C-x !)'
+     List the possible completions of the text before point, treating it
+     as a command name.
+
+'dynamic-complete-history (M-<TAB>)'
+     Attempt completion on the text before point, comparing the text
+     against lines from the history list for possible completion
+     matches.
+
+'dabbrev-expand ()'
+     Attempt menu completion on the text before point, comparing the
+     text against lines from the history list for possible completion
+     matches.
+
+'complete-into-braces (M-{)'
+     Perform filename completion and insert the list of possible
+     completions enclosed within braces so the list is available to the
+     shell (*note Brace Expansion::).

+8.4.7 Keyboard Macros
+---------------------
+
+'start-kbd-macro (C-x ()'
+     Begin saving the characters typed into the current keyboard macro.
+
+'end-kbd-macro (C-x ))'
+     Stop saving the characters typed into the current keyboard macro
+     and save the definition.
+
+'call-last-kbd-macro (C-x e)'
+     Re-execute the last keyboard macro defined, by making the
+     characters in the macro appear as if typed at the keyboard.
+
+'print-last-kbd-macro ()'
+     Print the last keyboard macro defined in a format suitable for the
+     INPUTRC file.

+
+8.4.8 Some Miscellaneous Commands
+---------------------------------
+
+'re-read-init-file (C-x C-r)'
+     Read in the contents of the INPUTRC file, and incorporate any
+     bindings or variable assignments found there.
+
+'abort (C-g)'
+     Abort the current editing command and ring the terminal's bell
+     (subject to the setting of 'bell-style').
+
+'do-lowercase-version (M-A, M-B, M-X, ...)'
+     If the metafied character X is upper case, run the command that is
+     bound to the corresponding metafied lower case character.  The
+     behavior is undefined if X is already lower case.
+
+'prefix-meta (<ESC>)'
+     Metafy the next character typed.  This is for keyboards without a
+     meta key.  Typing '<ESC> f' is equivalent to typing 'M-f'.
+
+'undo (C-_ or C-x C-u)'
+     Incremental undo, separately remembered for each line.
+
+'revert-line (M-r)'
+     Undo all changes made to this line.  This is like executing the
+     'undo' command enough times to get back to the beginning.
+
+'tilde-expand (M-&)'
+     Perform tilde expansion on the current word.
+
+'set-mark (C-@)'
+     Set the mark to the point.  If a numeric argument is supplied, the
+     mark is set to that position.
+
+'exchange-point-and-mark (C-x C-x)'
+     Swap the point with the mark.  The current cursor position is set
+     to the saved position, and the old cursor position is saved as the
+     mark.
+
+'character-search (C-])'
+     A character is read and point is moved to the next occurrence of
+     that character.  A negative argument searches for previous
+     occurrences.
+
+'character-search-backward (M-C-])'
+     A character is read and point is moved to the previous occurrence
+     of that character.  A negative argument searches for subsequent
+     occurrences.
+
+'skip-csi-sequence ()'
+     Read enough characters to consume a multi-key sequence such as
+     those defined for keys like Home and End.  Such sequences begin
+     with a Control Sequence Indicator (CSI), usually ESC-[.  If this
+     sequence is bound to "\e[", keys producing such sequences will have
+     no effect unless explicitly bound to a Readline command, instead of
+     inserting stray characters into the editing buffer.  This is
+     unbound by default, but usually bound to ESC-[.
+
+'insert-comment (M-#)'
+     Without a numeric argument, the value of the 'comment-begin'
+     variable is inserted at the beginning of the current line.  If a
+     numeric argument is supplied, this command acts as a toggle: if the
+     characters at the beginning of the line do not match the value of
+     'comment-begin', the value is inserted, otherwise the characters in
+     'comment-begin' are deleted from the beginning of the line.  In
+     either case, the line is accepted as if a newline had been typed.
+     The default value of 'comment-begin' causes this command to make
+     the current line a shell comment.  If a numeric argument causes the
+     comment character to be removed, the line will be executed by the
+     shell.
+
+'dump-functions ()'
+     Print all of the functions and their key bindings to the Readline
+     output stream.  If a numeric argument is supplied, the output is
+     formatted in such a way that it can be made part of an INPUTRC
+     file.  This command is unbound by default.
+
+'dump-variables ()'
+     Print all of the settable variables and their values to the
+     Readline output stream.  If a numeric argument is supplied, the
+     output is formatted in such a way that it can be made part of an
+     INPUTRC file.  This command is unbound by default.
+
+'dump-macros ()'
+     Print all of the Readline key sequences bound to macros and the
+     strings they output.  If a numeric argument is supplied, the output
+     is formatted in such a way that it can be made part of an INPUTRC
+     file.  This command is unbound by default.
+
+'spell-correct-word (C-x s)'
+     Perform spelling correction on the current word, treating it as a
+     directory or filename, in the same way as the 'cdspell' shell
+     option.  Word boundaries are the same as those used by
+     'shell-forward-word'.
+
+'glob-complete-word (M-g)'
+     The word before point is treated as a pattern for pathname
+     expansion, with an asterisk implicitly appended.  This pattern is
+     used to generate a list of matching file names for possible
+     completions.
+
+'glob-expand-word (C-x *)'
+     The word before point is treated as a pattern for pathname
+     expansion, and the list of matching file names is inserted,
+     replacing the word.  If a numeric argument is supplied, a '*' is
+     appended before pathname expansion.
+
+'glob-list-expansions (C-x g)'
+     The list of expansions that would have been generated by
+     'glob-expand-word' is displayed, and the line is redrawn.  If a
+     numeric argument is supplied, a '*' is appended before pathname
+     expansion.
+
+'display-shell-version (C-x C-v)'
+     Display version information about the current instance of Bash.
+
+'shell-expand-line (M-C-e)'
+     Expand the line as the shell does.  This performs alias and history
+     expansion as well as all of the shell word expansions (*note Shell
+     Expansions::).
+
+'history-expand-line (M-^)'
+     Perform history expansion on the current line.
+
+'magic-space ()'
+     Perform history expansion on the current line and insert a space
+     (*note History Interaction::).
+
+'alias-expand-line ()'
+     Perform alias expansion on the current line (*note Aliases::).
+
+'history-and-alias-expand-line ()'
+     Perform history and alias expansion on the current line.
+
+'insert-last-argument (M-. or M-_)'
+     A synonym for 'yank-last-arg'.
+
+'edit-and-execute-command (C-x C-e)'
+     Invoke an editor on the current command line, and execute the
+     result as shell commands.  Bash attempts to invoke '$VISUAL',
+     '$EDITOR', and 'emacs' as the editor, in that order.

+8.5 Readline vi Mode
+====================
+
+While the Readline library does not have a full set of 'vi' editing
+functions, it does contain enough to allow simple editing of the line.
+The Readline 'vi' mode behaves as specified in the POSIX standard.
+
+   In order to switch interactively between 'emacs' and 'vi' editing
+modes, use the 'set -o emacs' and 'set -o vi' commands (*note The Set
+Builtin::).  The Readline default is 'emacs' mode.
+
+   When you enter a line in 'vi' mode, you are already placed in
+'insertion' mode, as if you had typed an 'i'.  Pressing <ESC> switches
+you into 'command' mode, where you can edit the text of the line with
+the standard 'vi' movement keys, move to previous history lines with 'k'
+and subsequent lines with 'j', and so forth.

+
+8.6 Programmable Completion
+===========================
+
+When word completion is attempted for an argument to a command for which
+a completion specification (a COMPSPEC) has been defined using the
+'complete' builtin (*note Programmable Completion Builtins::), the
+programmable completion facilities are invoked.
+
+   First, the command name is identified.  If a compspec has been
+defined for that command, the compspec is used to generate the list of
+possible completions for the word.  If the command word is the empty
+string (completion attempted at the beginning of an empty line), any
+compspec defined with the '-E' option to 'complete' is used.  If the
+command word is a full pathname, a compspec for the full pathname is
+searched for first.  If no compspec is found for the full pathname, an
+attempt is made to find a compspec for the portion following the final
+slash.  If those searches do not result in a compspec, any compspec
+defined with the '-D' option to 'complete' is used as the default.  If
+there is no default compspec, Bash attempts alias expansion on the
+command word as a final resort, and attempts to find a compspec for the
+command word from any successful expansion
+
+   Once a compspec has been found, it is used to generate the list of
+matching words.  If a compspec is not found, the default Bash completion
+described above (*note Commands For Completion::) is performed.
+
+   First, the actions specified by the compspec are used.  Only matches
+which are prefixed by the word being completed are returned.  When the
+'-f' or '-d' option is used for filename or directory name completion,
+the shell variable 'FIGNORE' is used to filter the matches.  *Note Bash
+Variables::, for a description of 'FIGNORE'.
+
+   Any completions specified by a filename expansion pattern to the '-G'
+option are generated next.  The words generated by the pattern need not
+match the word being completed.  The 'GLOBIGNORE' shell variable is not
+used to filter the matches, but the 'FIGNORE' shell variable is used.
+
+   Next, the string specified as the argument to the '-W' option is
+considered.  The string is first split using the characters in the 'IFS'
+special variable as delimiters.  Shell quoting is honored within the
+string, in order to provide a mechanism for the words to contain shell
+metacharacters or characters in the value of 'IFS'.  Each word is then
+expanded using brace expansion, tilde expansion, parameter and variable
+expansion, command substitution, and arithmetic expansion, as described
+above (*note Shell Expansions::).  The results are split using the rules
+described above (*note Word Splitting::).  The results of the expansion
+are prefix-matched against the word being completed, and the matching
+words become the possible completions.
+
+   After these matches have been generated, any shell function or
+command specified with the '-F' and '-C' options is invoked.  When the
+command or function is invoked, the 'COMP_LINE', 'COMP_POINT',
+'COMP_KEY', and 'COMP_TYPE' variables are assigned values as described
+above (*note Bash Variables::).  If a shell function is being invoked,
+the 'COMP_WORDS' and 'COMP_CWORD' variables are also set.  When the
+function or command is invoked, the first argument ($1) is the name of
+the command whose arguments are being completed, the second argument
+($2) is the word being completed, and the third argument ($3) is the
+word preceding the word being completed on the current command line.  No
+filtering of the generated completions against the word being completed
+is performed; the function or command has complete freedom in generating
+the matches.
+
+   Any function specified with '-F' is invoked first.  The function may
+use any of the shell facilities, including the 'compgen' and 'compopt'
+builtins described below (*note Programmable Completion Builtins::), to
+generate the matches.  It must put the possible completions in the
+'COMPREPLY' array variable, one per array element.
+
+   Next, any command specified with the '-C' option is invoked in an
+environment equivalent to command substitution.  It should print a list
+of completions, one per line, to the standard output.  Backslash may be
+used to escape a newline, if necessary.
+
+   After all of the possible completions are generated, any filter
+specified with the '-X' option is applied to the list.  The filter is a
+pattern as used for pathname expansion; a '&' in the pattern is replaced
+with the text of the word being completed.  A literal '&' may be escaped
+with a backslash; the backslash is removed before attempting a match.
+Any completion that matches the pattern will be removed from the list.
+A leading '!' negates the pattern; in this case any completion not
+matching the pattern will be removed.  If the 'nocasematch' shell option
+(see the description of 'shopt' in *note The Shopt Builtin::) is
+enabled, the match is performed without regard to the case of alphabetic
+characters.
+
+   Finally, any prefix and suffix specified with the '-P' and '-S'
+options are added to each member of the completion list, and the result
+is returned to the Readline completion code as the list of possible
+completions.
+
+   If the previously-applied actions do not generate any matches, and
+the '-o dirnames' option was supplied to 'complete' when the compspec
+was defined, directory name completion is attempted.
+
+   If the '-o plusdirs' option was supplied to 'complete' when the
+compspec was defined, directory name completion is attempted and any
+matches are added to the results of the other actions.
+
+   By default, if a compspec is found, whatever it generates is returned
+to the completion code as the full set of possible completions.  The
+default Bash completions are not attempted, and the Readline default of
+filename completion is disabled.  If the '-o bashdefault' option was
+supplied to 'complete' when the compspec was defined, the default Bash
+completions are attempted if the compspec generates no matches.  If the
+'-o default' option was supplied to 'complete' when the compspec was
+defined, Readline's default completion will be performed if the compspec
+(and, if attempted, the default Bash completions) generate no matches.
+
+   When a compspec indicates that directory name completion is desired,
+the programmable completion functions force Readline to append a slash
+to completed names which are symbolic links to directories, subject to
+the value of the MARK-DIRECTORIES Readline variable, regardless of the
+setting of the MARK-SYMLINKED-DIRECTORIES Readline variable.
+
+   There is some support for dynamically modifying completions.  This is
+most useful when used in combination with a default completion specified
+with '-D'.  It's possible for shell functions executed as completion
+handlers to indicate that completion should be retried by returning an
+exit status of 124.  If a shell function returns 124, and changes the
+compspec associated with the command on which completion is being
+attempted (supplied as the first argument when the function is
+executed), programmable completion restarts from the beginning, with an
+attempt to find a new compspec for that command.  This allows a set of
+completions to be built dynamically as completion is attempted, rather
+than being loaded all at once.
+
+   For instance, assuming that there is a library of compspecs, each
+kept in a file corresponding to the name of the command, the following
+default completion function would load completions dynamically:
+
+     _completion_loader()
+     {
+         . "/etc/bash_completion.d/$1.sh" >/dev/null 2>&1 && return 124
+     }
+     complete -D -F _completion_loader -o bashdefault -o default

+
+8.7 Programmable Completion Builtins
+====================================
+
+Three builtin commands are available to manipulate the programmable
+completion facilities: one to specify how the arguments to a particular
+command are to be completed, and two to modify the completion as it is
+happening.
+
+'compgen'
+          compgen [OPTION] [WORD]
+
+     Generate possible completion matches for WORD according to the
+     OPTIONs, which may be any option accepted by the 'complete' builtin
+     with the exception of '-p' and '-r', and write the matches to the
+     standard output.  When using the '-F' or '-C' options, the various
+     shell variables set by the programmable completion facilities,
+     while available, will not have useful values.
+
+     The matches will be generated in the same way as if the
+     programmable completion code had generated them directly from a
+     completion specification with the same flags.  If WORD is
+     specified, only those completions matching WORD will be displayed.
+
+     The return value is true unless an invalid option is supplied, or
+     no matches were generated.
+
+'complete'
+          complete [-abcdefgjksuv] [-o COMP-OPTION] [-DEI] [-A ACTION] [-G GLOBPAT]
+          [-W WORDLIST] [-F FUNCTION] [-C COMMAND] [-X FILTERPAT]
+          [-P PREFIX] [-S SUFFIX] NAME [NAME ...]
+          complete -pr [-DEI] [NAME ...]
+
+     Specify how arguments to each NAME should be completed.  If the
+     '-p' option is supplied, or if no options are supplied, existing
+     completion specifications are printed in a way that allows them to
+     be reused as input.  The '-r' option removes a completion
+     specification for each NAME, or, if no NAMEs are supplied, all
+     completion specifications.  The '-D' option indicates that other
+     supplied options and actions should apply to the "default" command
+     completion; that is, completion attempted on a command for which no
+     completion has previously been defined.  The '-E' option indicates
+     that other supplied options and actions should apply to "empty"
+     command completion; that is, completion attempted on a blank line.
+     The '-I' option indicates that other supplied options and actions
+     should apply to completion on the initial non-assignment word on
+     the line, or after a command delimiter such as ';' or '|', which is
+     usually command name completion.  If multiple options are supplied,
+     the '-D' option takes precedence over '-E', and both take
+     precedence over '-I'.  If any of '-D', '-E', or '-I' are supplied,
+     any other NAME arguments are ignored; these completions only apply
+     to the case specified by the option.
+
+     The process of applying these completion specifications when word
+     completion is attempted is described above (*note Programmable
+     Completion::).
+
+     Other options, if specified, have the following meanings.  The
+     arguments to the '-G', '-W', and '-X' options (and, if necessary,
+     the '-P' and '-S' options) should be quoted to protect them from
+     expansion before the 'complete' builtin is invoked.
+
+     '-o COMP-OPTION'
+          The COMP-OPTION controls several aspects of the compspec's
+          behavior beyond the simple generation of completions.
+          COMP-OPTION may be one of:
+
+          'bashdefault'
+               Perform the rest of the default Bash completions if the
+               compspec generates no matches.
+
+          'default'
+               Use Readline's default filename completion if the
+               compspec generates no matches.
+
+          'dirnames'
+               Perform directory name completion if the compspec
+               generates no matches.
+
+          'filenames'
+               Tell Readline that the compspec generates filenames, so
+               it can perform any filename-specific processing (like
+               adding a slash to directory names, quoting special
+               characters, or suppressing trailing spaces).  This option
+               is intended to be used with shell functions specified
+               with '-F'.
+
+          'noquote'
+               Tell Readline not to quote the completed words if they
+               are filenames (quoting filenames is the default).
+
+          'nosort'
+               Tell Readline not to sort the list of possible
+               completions alphabetically.
+
+          'nospace'
+               Tell Readline not to append a space (the default) to
+               words completed at the end of the line.
+
+          'plusdirs'
+               After any matches defined by the compspec are generated,
+               directory name completion is attempted and any matches
+               are added to the results of the other actions.
+
+     '-A ACTION'
+          The ACTION may be one of the following to generate a list of
+          possible completions:
+
+          'alias'
+               Alias names.  May also be specified as '-a'.
+
+          'arrayvar'
+               Array variable names.
+
+          'binding'
+               Readline key binding names (*note Bindable Readline
+               Commands::).
+
+          'builtin'
+               Names of shell builtin commands.  May also be specified
+               as '-b'.
+
+          'command'
+               Command names.  May also be specified as '-c'.
+
+          'directory'
+               Directory names.  May also be specified as '-d'.
+
+          'disabled'
+               Names of disabled shell builtins.
+
+          'enabled'
+               Names of enabled shell builtins.
+
+          'export'
+               Names of exported shell variables.  May also be specified
+               as '-e'.
+
+          'file'
+               File names.  May also be specified as '-f'.
+
+          'function'
+               Names of shell functions.
+
+          'group'
+               Group names.  May also be specified as '-g'.
+
+          'helptopic'
+               Help topics as accepted by the 'help' builtin (*note Bash
+               Builtins::).
+
+          'hostname'
+               Hostnames, as taken from the file specified by the
+               'HOSTFILE' shell variable (*note Bash Variables::).
+
+          'job'
+               Job names, if job control is active.  May also be
+               specified as '-j'.
+
+          'keyword'
+               Shell reserved words.  May also be specified as '-k'.
+
+          'running'
+               Names of running jobs, if job control is active.
+
+          'service'
+               Service names.  May also be specified as '-s'.
+
+          'setopt'
+               Valid arguments for the '-o' option to the 'set' builtin
+               (*note The Set Builtin::).
+
+          'shopt'
+               Shell option names as accepted by the 'shopt' builtin
+               (*note Bash Builtins::).
+
+          'signal'
+               Signal names.
+
+          'stopped'
+               Names of stopped jobs, if job control is active.
+
+          'user'
+               User names.  May also be specified as '-u'.
+
+          'variable'
+               Names of all shell variables.  May also be specified as
+               '-v'.
+
+     '-C COMMAND'
+          COMMAND is executed in a subshell environment, and its output
+          is used as the possible completions.  Arguments are passed as
+          with the '-F' option.
+
+     '-F FUNCTION'
+          The shell function FUNCTION is executed in the current shell
+          environment.  When it is executed, $1 is the name of the
+          command whose arguments are being completed, $2 is the word
+          being completed, and $3 is the word preceding the word being
+          completed, as described above (*note Programmable
+          Completion::).  When it finishes, the possible completions are
+          retrieved from the value of the 'COMPREPLY' array variable.
+
+     '-G GLOBPAT'
+          The filename expansion pattern GLOBPAT is expanded to generate
+          the possible completions.
+
+     '-P PREFIX'
+          PREFIX is added at the beginning of each possible completion
+          after all other options have been applied.
+
+     '-S SUFFIX'
+          SUFFIX is appended to each possible completion after all other
+          options have been applied.
+
+     '-W WORDLIST'
+          The WORDLIST is split using the characters in the 'IFS'
+          special variable as delimiters, and each resultant word is
+          expanded.  The possible completions are the members of the
+          resultant list which match the word being completed.
+
+     '-X FILTERPAT'
+          FILTERPAT is a pattern as used for filename expansion.  It is
+          applied to the list of possible completions generated by the
+          preceding options and arguments, and each completion matching
+          FILTERPAT is removed from the list.  A leading '!' in
+          FILTERPAT negates the pattern; in this case, any completion
+          not matching FILTERPAT is removed.
+
+     The return value is true unless an invalid option is supplied, an
+     option other than '-p' or '-r' is supplied without a NAME argument,
+     an attempt is made to remove a completion specification for a NAME
+     for which no specification exists, or an error occurs adding a
+     completion specification.
+
+'compopt'
+          compopt [-o OPTION] [-DEI] [+o OPTION] [NAME]
+     Modify completion options for each NAME according to the OPTIONs,
+     or for the currently-executing completion if no NAMEs are supplied.
+     If no OPTIONs are given, display the completion options for each
+     NAME or the current completion.  The possible values of OPTION are
+     those valid for the 'complete' builtin described above.  The '-D'
+     option indicates that other supplied options should apply to the
+     "default" command completion; that is, completion attempted on a
+     command for which no completion has previously been defined.  The
+     '-E' option indicates that other supplied options should apply to
+     "empty" command completion; that is, completion attempted on a
+     blank line.  The '-I' option indicates that other supplied options
+     should apply to completion on the initial non-assignment word on
+     the line, or after a command delimiter such as ';' or '|', which is
+     usually command name completion.
+
+     If multiple options are supplied, the '-D' option takes precedence
+     over '-E', and both take precedence over '-I'
+
+     The return value is true unless an invalid option is supplied, an
+     attempt is made to modify the options for a NAME for which no
+     completion specification exists, or an output error occurs.

+8.8 A Programmable Completion Example
+=====================================
+
+The most common way to obtain additional completion functionality beyond
+the default actions 'complete' and 'compgen' provide is to use a shell
+function and bind it to a particular command using 'complete -F'.
+
+   The following function provides completions for the 'cd' builtin.  It
+is a reasonably good example of what shell functions must do when used
+for completion.  This function uses the word passed as '$2' to determine
+the directory name to complete.  You can also use the 'COMP_WORDS' array
+variable; the current word is indexed by the 'COMP_CWORD' variable.
+
+   The function relies on the 'complete' and 'compgen' builtins to do
+much of the work, adding only the things that the Bash 'cd' does beyond
+accepting basic directory names: tilde expansion (*note Tilde
+Expansion::), searching directories in $CDPATH, which is described above
+(*note Bourne Shell Builtins::), and basic support for the 'cdable_vars'
+shell option (*note The Shopt Builtin::).  '_comp_cd' modifies the value
+of IFS so that it contains only a newline to accommodate file names
+containing spaces and tabs - 'compgen' prints the possible completions
+it generates one per line.
+
+   Possible completions go into the COMPREPLY array variable, one
+completion per array element.  The programmable completion system
+retrieves the completions from there when the function returns.

+             COMPREPLY=( $(compgen -v -- "$cur") )
+         fi
+
+         return 0
+     }
+
+   We install the completion function using the '-F' option to
+'complete':
+
+     # Tell readline to quote appropriate and append slashes to directories;
+     # use the bash default completion for other arguments
+     complete -o filenames -o nospace -o bashdefault -F _comp_cd cd
+
+Since we'd like Bash and Readline to take care of some of the other
+details for us, we use several other options to tell Bash and Readline
+what to do.  The '-o filenames' option tells Readline that the possible
+completions should be treated as filenames, and quoted appropriately.
+That option will also cause Readline to append a slash to filenames it
+can determine are directories (which is why we might want to extend
+'_comp_cd' to append a slash if we're using directories found via
+CDPATH: Readline can't tell those completions are directories).  The '-o
+nospace' option tells Readline to not append a space character to the
+directory name, in case we want to append to it.  The '-o bashdefault'
+option brings in the rest of the "Bash default" completions - possible
+completions that Bash adds to the default Readline set.  These include
+things like command name completion, variable completion for words
+beginning with '$' or '${', completions containing pathname expansion
+patterns (*note Filename Expansion::), and so on.
+
+   Once installed using 'complete', '_comp_cd' will be called every time
+we attempt word completion for a 'cd' command.
+
+   Many more examples - an extensive collection of completions for most
+of the common GNU, Unix, and Linux commands - are available as part of
+the bash_completion project.  This is installed by default on many
+GNU/Linux distributions.  Originally written by Ian Macdonald, the
+project now lives at <https://github.com/scop/bash-completion/>.  There
+are ports for other systems such as Solaris and Mac OS X.
+
+   An older version of the bash_completion package is distributed with
+bash in the 'examples/complete' subdirectory.

+
+This chapter describes how to use the GNU History Library interactively,

+
+9.1 Bash History Facilities
+===========================
+
+When the '-o history' option to the 'set' builtin is enabled (*note The
+Set Builtin::), the shell provides access to the "command history", the
+list of commands previously typed.  The value of the 'HISTSIZE' shell
+variable is used as the number of commands to save in a history list.
+The text of the last '$HISTSIZE' commands (default 500) is saved.  The
+shell stores each command in the history list prior to parameter and
+variable expansion but after history expansion is performed, subject to
+the values of the shell variables 'HISTIGNORE' and 'HISTCONTROL'.
+
+   When the shell starts up, the history is initialized from the file
+named by the 'HISTFILE' variable (default '~/.bash_history').  The file
+named by the value of 'HISTFILE' is truncated, if necessary, to contain
+no more than the number of lines specified by the value of the
+'HISTFILESIZE' variable.  When a shell with history enabled exits, the
+last '$HISTSIZE' lines are copied from the history list to the file
+named by '$HISTFILE'.  If the 'histappend' shell option is set (*note
+Bash Builtins::), the lines are appended to the history file, otherwise
+the history file is overwritten.  If 'HISTFILE' is unset, or if the
+history file is unwritable, the history is not saved.  After saving the
+history, the history file is truncated to contain no more than
+'$HISTFILESIZE' lines.  If 'HISTFILESIZE' is unset, or set to null, a
+non-numeric value, or a numeric value less than zero, the history file
+is not truncated.
+
+   If the 'HISTTIMEFORMAT' is set, the time stamp information associated
+with each history entry is written to the history file, marked with the
+history comment character.  When the history file is read, lines
+beginning with the history comment character followed immediately by a
+digit are interpreted as timestamps for the following history entry.
+
+   The builtin command 'fc' may be used to list or edit and re-execute a
+portion of the history list.  The 'history' builtin may be used to
+display or modify the history list and manipulate the history file.
+When using command-line editing, search commands are available in each
+editing mode that provide access to the history list (*note Commands For
+History::).
+
+   The shell allows control over which commands are saved on the history
+list.  The 'HISTCONTROL' and 'HISTIGNORE' variables may be set to cause
+the shell to save only a subset of the commands entered.  The 'cmdhist'
+shell option, if enabled, causes the shell to attempt to save each line
+of a multi-line command in the same history entry, adding semicolons
+where necessary to preserve syntactic correctness.  The 'lithist' shell
+option causes the shell to save the command with embedded newlines
+instead of semicolons.  The 'shopt' builtin is used to set these
+options.  *Note The Shopt Builtin::, for a description of 'shopt'.
+
+
+File: bashref.info,  Node: Bash History Builtins,  Next: History Interaction,  Prev: Bash History Facilities,  Up: Using History Interactively
+
+9.2 Bash History Builtins
+=========================
+
+Bash provides two builtin commands which manipulate the history list and
+history file.
+
+'fc'
+          fc [-e ENAME] [-lnr] [FIRST] [LAST]
+          fc -s [PAT=REP] [COMMAND]
+
+     The first form selects a range of commands from FIRST to LAST from
+     the history list and displays or edits and re-executes them.  Both
+     FIRST and LAST may be specified as a string (to locate the most
+     recent command beginning with that string) or as a number (an index
+     into the history list, where a negative number is used as an offset
+     from the current command number).
+
+     When listing, a FIRST or LAST of 0 is equivalent to -1 and -0 is
+     equivalent to the current command (usually the 'fc' command);
+     otherwise 0 is equivalent to -1 and -0 is invalid.
+
+     If LAST is not specified, it is set to FIRST.  If FIRST is not
+     specified, it is set to the previous command for editing and -16
+     for listing.  If the '-l' flag is given, the commands are listed on
+     standard output.  The '-n' flag suppresses the command numbers when
+     listing.  The '-r' flag reverses the order of the listing.
+     Otherwise, the editor given by ENAME is invoked on a file
+     containing those commands.  If ENAME is not given, the value of the
+     following variable expansion is used: '${FCEDIT:-${EDITOR:-vi}}'.
+     This says to use the value of the 'FCEDIT' variable if set, or the
+     value of the 'EDITOR' variable if that is set, or 'vi' if neither
+     is set.  When editing is complete, the edited commands are echoed
+     and executed.
+
+     In the second form, COMMAND is re-executed after each instance of
+     PAT in the selected command is replaced by REP.  COMMAND is
+     interpreted the same as FIRST above.
+
+     A useful alias to use with the 'fc' command is 'r='fc -s'', so that
+     typing 'r cc' runs the last command beginning with 'cc' and typing
+     'r' re-executes the last command (*note Aliases::).
+
+'history'
+          history [N]
+          history -c
+          history -d OFFSET
+          history -d START-END
+          history [-anrw] [FILENAME]
+          history -ps ARG
+
+     With no options, display the history list with line numbers.  Lines
+     prefixed with a '*' have been modified.  An argument of N lists
+     only the last N lines.  If the shell variable 'HISTTIMEFORMAT' is
+     set and not null, it is used as a format string for STRFTIME to
+     display the time stamp associated with each displayed history
+     entry.  No intervening blank is printed between the formatted time
+     stamp and the history line.
+
+     Options, if supplied, have the following meanings:
+
+     '-c'
+          Clear the history list.  This may be combined with the other
+          options to replace the history list completely.
+
+     '-d OFFSET'
+          Delete the history entry at position OFFSET.  If OFFSET is
+          positive, it should be specified as it appears when the
+          history is displayed.  If OFFSET is negative, it is
+          interpreted as relative to one greater than the last history
+          position, so negative indices count back from the end of the
+          history, and an index of '-1' refers to the current 'history
+          -d' command.
+
+     '-d START-END'
+          Delete the range of history entries between positions START
+          and END, inclusive.  Positive and negative values for START
+          and END are interpreted as described above.
+
+     '-a'
+          Append the new history lines to the history file.  These are
+          history lines entered since the beginning of the current Bash
+          session, but not already appended to the history file.
+
+     '-n'
+          Append the history lines not already read from the history
+          file to the current history list.  These are lines appended to
+          the history file since the beginning of the current Bash
+          session.
+
+     '-r'
+          Read the history file and append its contents to the history
+          list.
+
+     '-w'
+          Write out the current history list to the history file.
+
+     '-p'
+          Perform history substitution on the ARGs and display the
+          result on the standard output, without storing the results in
+          the history list.
+
+     '-s'
+          The ARGs are added to the end of the history list as a single
+          entry.
+
+     If a FILENAME argument is supplied when any of the '-w', '-r',
+     '-a', or '-n' options is used, Bash uses FILENAME as the history
+     file.  If not, then the value of the 'HISTFILE' variable is used.
+
+     The return value is 0 unless an invalid option is encountered, an
+     error occurs while reading or writing the history file, an invalid
+     OFFSET or range is supplied as an argument to '-d', or the history
+     expansion supplied as an argument to '-p' fails.
+
+

+
+9.3 History Expansion
+=====================
+
+The History library provides a history expansion feature that is similar
+to the history expansion provided by 'csh'.  This section describes the
+syntax used to manipulate the history information.
+
+   History expansions introduce words from the history list into the
+input stream, making it easy to repeat commands, insert the arguments to
+a previous command into the current input line, or fix errors in
+previous commands quickly.
+
+   History expansion is performed immediately after a complete line is
+read, before the shell breaks it into words, and is performed on each
+line individually.  Bash attempts to inform the history expansion
+functions about quoting still in effect from previous lines.
+
+   History expansion takes place in two parts.  The first is to
+determine which line from the history list should be used during
+substitution.  The second is to select portions of that line for
+inclusion into the current one.  The line selected from the history is
+called the "event", and the portions of that line that are acted upon
+are called "words".  Various "modifiers" are available to manipulate the
+selected words.  The line is broken into words in the same fashion that
+Bash does, so that several words surrounded by quotes are considered one
+word.  History expansions are introduced by the appearance of the
+history expansion character, which is '!' by default.
+
+   History expansion implements shell-like quoting conventions: a
+backslash can be used to remove the special handling for the next
+character; single quotes enclose verbatim sequences of characters, and
+can be used to inhibit history expansion; and characters enclosed within
+double quotes may be subject to history expansion, since backslash can
+escape the history expansion character, but single quotes may not, since
+they are not treated specially within double quotes.
+
+   When using the shell, only '\' and ''' may be used to escape the
+history expansion character, but the history expansion character is also
+treated as quoted if it immediately precedes the closing double quote in
+a double-quoted string.
+
+   Several shell options settable with the 'shopt' builtin (*note The
+Shopt Builtin::) may be used to tailor the behavior of history
+expansion.  If the 'histverify' shell option is enabled, and Readline is
+being used, history substitutions are not immediately passed to the
+shell parser.  Instead, the expanded line is reloaded into the Readline
+editing buffer for further modification.  If Readline is being used, and
+the 'histreedit' shell option is enabled, a failed history expansion
+will be reloaded into the Readline editing buffer for correction.  The
+'-p' option to the 'history' builtin command may be used to see what a
+history expansion will do before using it.  The '-s' option to the
+'history' builtin may be used to add commands to the end of the history
+list without actually executing them, so that they are available for
+subsequent recall.  This is most useful in conjunction with Readline.
+
+   The shell allows control of the various characters used by the
+history expansion mechanism with the 'histchars' variable, as explained
+above (*note Bash Variables::).  The shell uses the history comment
+character to mark history timestamps when writing the history file.

+
+
+File: bashref.info,  Node: Event Designators,  Next: Word Designators,  Up: History Interaction
+
+9.3.1 Event Designators
+-----------------------
+
+An event designator is a reference to a command line entry in the
+history list.  Unless the reference is absolute, events are relative to
+the current position in the history list.
+
+'!'
+     Start a history substitution, except when followed by a space, tab,
+     the end of the line, '=' or '(' (when the 'extglob' shell option is
+     enabled using the 'shopt' builtin).
+
+'!N'
+     Refer to command line N.
+
+'!-N'
+     Refer to the command N lines back.
+
+'!!'
+     Refer to the previous command.  This is a synonym for '!-1'.
+
+'!STRING'
+     Refer to the most recent command preceding the current position in
+     the history list starting with STRING.
+
+'!?STRING[?]'
+     Refer to the most recent command preceding the current position in
+     the history list containing STRING.  The trailing '?' may be
+     omitted if the STRING is followed immediately by a newline.  If
+     STRING is missing, the string from the most recent search is used;
+     it is an error if there is no previous search string.
+
+'^STRING1^STRING2^'
+     Quick Substitution.  Repeat the last command, replacing STRING1
+     with STRING2.  Equivalent to '!!:s^STRING1^STRING2^'.
+
+'!#'
+     The entire command line typed so far.
+
+
+File: bashref.info,  Node: Word Designators,  Next: Modifiers,  Prev: Event Designators,  Up: History Interaction
+
+9.3.2 Word Designators
+----------------------
+
+Word designators are used to select desired words from the event.  A ':'
+separates the event specification from the word designator.  It may be
+omitted if the word designator begins with a '^', '$', '*', '-', or '%'.
+Words are numbered from the beginning of the line, with the first word
+being denoted by 0 (zero).  Words are inserted into the current line
+separated by single spaces.
+
+   For example,
+
+'!!'
+     designates the preceding command.  When you type this, the
+     preceding command is repeated in toto.
+
+'!!:$'
+     designates the last argument of the preceding command.  This may be
+     shortened to '!$'.
+
+'!fi:2'
+     designates the second argument of the most recent command starting
+     with the letters 'fi'.
+
+   Here are the word designators:
+
+'0 (zero)'
+     The '0'th word.  For many applications, this is the command word.
+
+'N'
+     The Nth word.
+
+'^'
+     The first argument; that is, word 1.
+
+'$'
+     The last argument.
+
+'%'
+     The first word matched by the most recent '?STRING?' search, if the
+     search string begins with a character that is part of a word.
+
+'X-Y'
+     A range of words; '-Y' abbreviates '0-Y'.
+
+'*'
+     All of the words, except the '0'th.  This is a synonym for '1-$'.
+     It is not an error to use '*' if there is just one word in the
+     event; the empty string is returned in that case.
+
+'X*'
+     Abbreviates 'X-$'
+
+'X-'
+     Abbreviates 'X-$' like 'X*', but omits the last word.  If 'x' is
+     missing, it defaults to 0.
+
+   If a word designator is supplied without an event specification, the
+previous command is used as the event.
+
+
+File: bashref.info,  Node: Modifiers,  Prev: Word Designators,  Up: History Interaction
+
+9.3.3 Modifiers
+---------------
+
+After the optional word designator, you can add a sequence of one or
+more of the following modifiers, each preceded by a ':'.  These modify,
+or edit, the word or words selected from the history event.
+
+'h'
+     Remove a trailing pathname component, leaving only the head.
+
+'t'
+     Remove all leading pathname components, leaving the tail.
+
+'r'
+     Remove a trailing suffix of the form '.SUFFIX', leaving the
+     basename.
+
+'e'
+     Remove all but the trailing suffix.
+
+'p'
+     Print the new command but do not execute it.
+
+'q'
+     Quote the substituted words, escaping further substitutions.
+
+'x'
+     Quote the substituted words as with 'q', but break into words at
+     spaces, tabs, and newlines.  The 'q' and 'x' modifiers are mutually
+     exclusive; the last one supplied is used.
+
+'s/OLD/NEW/'
+     Substitute NEW for the first occurrence of OLD in the event line.
+     Any character may be used as the delimiter in place of '/'.  The
+     delimiter may be quoted in OLD and NEW with a single backslash.  If
+     '&' appears in NEW, it is replaced by OLD.  A single backslash will
+     quote the '&'.  If OLD is null, it is set to the last OLD
+     substituted, or, if no previous history substitutions took place,
+     the last STRING in a !?STRING'[?]' search.  If NEW is null, each
+     matching OLD is deleted.  The final delimiter is optional if it is
+     the last character on the input line.
+
+'&'
+     Repeat the previous substitution.
+
+'g'
+'a'
+     Cause changes to be applied over the entire event line.  Used in
+     conjunction with 's', as in 'gs/OLD/NEW/', or with '&'.
+
+'G'
+     Apply the following 's' or '&' modifier once to each word in the
+     event.

+
+10.1 Basic Installation
+=======================
+
+These are installation instructions for Bash.
+
+   The simplest way to compile Bash is:
+
+  1. 'cd' to the directory containing the source code and type
+     './configure' to configure Bash for your system.  If you're using
+     'csh' on an old version of System V, you might need to type 'sh
+     ./configure' instead to prevent 'csh' from trying to execute
+     'configure' itself.
+
+     Running 'configure' takes some time.  While running, it prints
+     messages telling which features it is checking for.
+
+  2. Type 'make' to compile Bash and build the 'bashbug' bug reporting
+     script.
+
+  3. Optionally, type 'make tests' to run the Bash test suite.
+
+  4. Type 'make install' to install 'bash' and 'bashbug'.  This will
+     also install the manual pages and Info file, message translation
+     files, some supplemental documentation, a number of example
+     loadable builtin commands, and a set of header files for developing
+     loadable builtins.  You may need additional privileges to install
+     'bash' to your desired destination, so 'sudo make install' might be
+     required.  More information about controlling the locations where
+     'bash' and other files are installed is below (*note Installation
+     Names::).
+
+   The 'configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a 'Makefile' in each directory of the package
+(the top directory, the 'builtins', 'doc', 'po', and 'support'
+directories, each directory under 'lib', and several others).  It also
+creates a 'config.h' file containing system-dependent definitions.
+Finally, it creates a shell script named 'config.status' that you can
+run in the future to recreate the current configuration, a file
+'config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file 'config.log' containing compiler output
+(useful mainly for debugging 'configure').  If at some point
+'config.cache' contains results you don't want to keep, you may remove
+or edit it.
+
+   To find out more about the options and arguments that the 'configure'
+script understands, type
+
+     bash-4.2$ ./configure --help
+
+at the Bash prompt in your Bash source directory.
+
+   If you want to build Bash in a directory separate from the source
+directory - to build for multiple architectures, for example - just use
+the full path to the configure script.  The following commands will
+build bash in a directory under '/usr/local/build' from the source code
+in '/usr/local/src/bash-4.4':
+
+     mkdir /usr/local/build/bash-4.4
+     cd /usr/local/build/bash-4.4
+     bash /usr/local/src/bash-4.4/configure
+     make
+
+   See *note Compiling For Multiple Architectures:: for more information
+about building in a directory separate from the source.
+
+   If you need to do unusual things to compile Bash, please try to
+figure out how 'configure' could check whether or not to do them, and
+mail diffs or instructions to <bash-maintainers@gnu.org> so they can be
+considered for the next release.
+
+   The file 'configure.ac' is used to create 'configure' by a program
+called Autoconf.  You only need 'configure.ac' if you want to change it
+or regenerate 'configure' using a newer version of Autoconf.  If you do
+this, make sure you are using Autoconf version 2.69 or newer.
+
+   You can remove the program binaries and object files from the source
+code directory by typing 'make clean'.  To also remove the files that
+'configure' created (so you can compile Bash for a different kind of
+computer), type 'make distclean'.

+
+10.2 Compilers and Options
+==========================
+
+Some systems require unusual options for compilation or linking that the
+'configure' script does not know about.  You can give 'configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+   On systems that have the 'env' program, you can do it like this:
+
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+   The configuration process uses GCC to build Bash if it is available.
+
+
+File: bashref.info,  Node: Compiling For Multiple Architectures,  Next: Installation Names,  Prev: Compilers and Options,  Up: Installing Bash
+
+10.3 Compiling For Multiple Architectures
+=========================================
+
+You can compile Bash for more than one kind of computer at the same
+time, by placing the object files for each architecture in their own
+directory.  To do this, you must use a version of 'make' that supports
+the 'VPATH' variable, such as GNU 'make'.  'cd' to the directory where
+you want the object files and executables to go and run the 'configure'
+script from the source directory (*note Basic Installation::).  You may
+need to supply the '--srcdir=PATH' argument to tell 'configure' where
+the source files are.  'configure' automatically checks for the source
+code in the directory that 'configure' is in and in '..'.
+
+   If you have to use a 'make' that does not support the 'VPATH'
+variable, you can compile Bash for one architecture at a time in the
+source code directory.  After you have installed Bash for one
+architecture, use 'make distclean' before reconfiguring for another
+architecture.
+
+   Alternatively, if your system supports symbolic links, you can use
+the 'support/mkclone' script to create a build tree which has symbolic
+links back to each file in the source directory.  Here's an example that
+creates a build directory in the current directory from a source
+directory '/usr/gnu/src/bash-2.0':
+
+     bash /usr/gnu/src/bash-2.0/support/mkclone -s /usr/gnu/src/bash-2.0 .
+
+The 'mkclone' script requires Bash, so you must have already built Bash
+for at least one architecture before you can create build directories
+for other architectures.
+
+
+File: bashref.info,  Node: Installation Names,  Next: Specifying the System Type,  Prev: Compiling For Multiple Architectures,  Up: Installing Bash
+
+10.4 Installation Names
+=======================
+
+By default, 'make install' will install into '/usr/local/bin',
+'/usr/local/man', etc.; that is, the "installation prefix" defaults to
+'/usr/local'.  You can specify an installation prefix other than
+'/usr/local' by giving 'configure' the option '--prefix=PATH', or by
+specifying a value for the 'prefix' 'make' variable when running 'make
+install' (e.g., 'make install prefix=PATH').  The 'prefix' variable
+provides a default for 'exec_prefix' and other variables used when
+installing bash.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give 'configure' the option '--exec-prefix=PATH', 'make install' will
+use PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   If you would like to change the installation locations for a single
+run, you can specify these variables as arguments to 'make': 'make
+install exec_prefix=/' will install 'bash' and 'bashbug' into '/bin'
+instead of the default '/usr/local/bin'.
+
+   If you want to see the files bash will install and where it will
+install them without changing anything on your system, specify the
+variable 'DESTDIR' as an argument to 'make'.  Its value should be the
+absolute directory path you'd like to use as the root of your sample
+installation tree.  For example,
+
+     mkdir /fs1/bash-install
+     make install DESTDIR=/fs1/bash-install
+
+will install 'bash' into '/fs1/bash-install/usr/local/bin/bash', the
+documentation into directories within
+'/fs1/bash-install/usr/local/share', the example loadable builtins into
+'/fs1/bash-install/usr/local/lib/bash', and so on.  You can use the
+usual 'exec_prefix' and 'prefix' variables to alter the directory paths
+beneath the value of 'DESTDIR'.
+
+   The GNU Makefile standards provide a more complete description of
+these variables and their effects.
+
+
+File: bashref.info,  Node: Specifying the System Type,  Next: Sharing Defaults,  Prev: Installation Names,  Up: Installing Bash
+
+10.5 Specifying the System Type
+===============================
+
+There may be some features 'configure' can not figure out automatically,
+but needs to determine by the type of host Bash will run on.  Usually
+'configure' can figure that out, but if it prints a message saying it
+can not guess the host type, give it the '--host=TYPE' option.  'TYPE'
+can either be a short name for the system type, such as 'sun4', or a
+canonical name with three fields: 'CPU-COMPANY-SYSTEM' (e.g.,
+'i386-unknown-freebsd4.2').
+
+   See the file 'support/config.sub' for the possible values of each
+field.
+
+
+File: bashref.info,  Node: Sharing Defaults,  Next: Operation Controls,  Prev: Specifying the System Type,  Up: Installing Bash
+
+10.6 Sharing Defaults
+=====================
+
+If you want to set default values for 'configure' scripts to share, you
+can create a site shell script called 'config.site' that gives default
+values for variables like 'CC', 'cache_file', and 'prefix'.  'configure'
+looks for 'PREFIX/share/config.site' if it exists, then
+'PREFIX/etc/config.site' if it exists.  Or, you can set the
+'CONFIG_SITE' environment variable to the location of the site script.
+A warning: the Bash 'configure' looks for a site script, but not all
+'configure' scripts do.
+
+
+File: bashref.info,  Node: Operation Controls,  Next: Optional Features,  Prev: Sharing Defaults,  Up: Installing Bash
+
+10.7 Operation Controls
+=======================
+
+'configure' recognizes the following options to control how it operates.
+
+'--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     './config.cache'.  Set FILE to '/dev/null' to disable caching, for
+     debugging 'configure'.
+
+'--help'
+     Print a summary of the options to 'configure', and exit.
+
+'--quiet'
+'--silent'
+'-q'
+     Do not print messages saying which checks are being made.
+
+'--srcdir=DIR'
+     Look for the Bash source code in directory DIR.  Usually
+     'configure' can determine that directory automatically.
+
+'--version'
+     Print the version of Autoconf used to generate the 'configure'
+     script, and exit.
+
+   'configure' also accepts some other, not widely used, boilerplate
+options.  'configure --help' prints the complete list.
+
+
+File: bashref.info,  Node: Optional Features,  Prev: Operation Controls,  Up: Installing Bash
+
+10.8 Optional Features
+======================
+
+The Bash 'configure' has a number of '--enable-FEATURE' options, where
+FEATURE indicates an optional part of Bash.  There are also several
+'--with-PACKAGE' options, where PACKAGE is something like 'bash-malloc'
+or 'purify'.  To turn off the default use of a package, use
+'--without-PACKAGE'.  To configure Bash without a feature that is
+enabled by default, use '--disable-FEATURE'.
+
+   Here is a complete list of the '--enable-' and '--with-' options that
+the Bash 'configure' recognizes.
+
+'--with-afs'
+     Define if you are using the Andrew File System from Transarc.
+
+'--with-bash-malloc'
+     Use the Bash version of 'malloc' in the directory 'lib/malloc'.
+     This is not the same 'malloc' that appears in GNU libc, but an
+     older version originally derived from the 4.2 BSD 'malloc'.  This
+     'malloc' is very fast, but wastes some space on each allocation.
+     This option is enabled by default.  The 'NOTES' file contains a
+     list of systems for which this should be turned off, and
+     'configure' disables this option automatically for a number of
+     systems.
+
+'--with-curses'
+     Use the curses library instead of the termcap library.  This should
+     be supplied if your system has an inadequate or incomplete termcap
+     database.
+
+'--with-gnu-malloc'
+     A synonym for '--with-bash-malloc'.
+
+'--with-installed-readline[=PREFIX]'
+     Define this to make Bash link with a locally-installed version of
+     Readline rather than the version in 'lib/readline'.  This works
+     only with Readline 5.0 and later versions.  If PREFIX is 'yes' or
+     not supplied, 'configure' uses the values of the make variables
+     'includedir' and 'libdir', which are subdirectories of 'prefix' by
+     default, to find the installed version of Readline if it is not in
+     the standard system include and library directories.  If PREFIX is
+     'no', Bash links with the version in 'lib/readline'.  If PREFIX is
+     set to any other value, 'configure' treats it as a directory
+     pathname and looks for the installed version of Readline in
+     subdirectories of that directory (include files in PREFIX/'include'
+     and the library in PREFIX/'lib').
+
+'--with-libintl-prefix[=PREFIX]'
+     Define this to make Bash link with a locally-installed version of
+     the libintl library instead of the version in 'lib/intl'.
+
+'--with-libiconv-prefix[=PREFIX]'
+     Define this to make Bash look for libiconv in PREFIX instead of the
+     standard system locations.  There is no version included with Bash.
+
+'--enable-minimal-config'
+     This produces a shell with minimal features, close to the
+     historical Bourne shell.
+
+   There are several '--enable-' options that alter how Bash is
+compiled, linked, and installed, rather than changing run-time features.
+
+'--enable-largefile'
+     Enable support for large files
+     (http://www.unix.org/version2/whatsnew/lfs20mar.html) if the
+     operating system requires special compiler options to build
+     programs which can access large files.  This is enabled by default,
+     if the operating system provides large file support.
+
+'--enable-profiling'
+     This builds a Bash binary that produces profiling information to be
+     processed by 'gprof' each time it is executed.
+
+'--enable-separate-helpfiles'
+     Use external files for the documentation displayed by the 'help'
+     builtin instead of storing the text internally.
+
+'--enable-static-link'
+     This causes Bash to be linked statically, if 'gcc' is being used.
+     This could be used to build a version to use as root's shell.
+
+   The 'minimal-config' option can be used to disable all of the
+following options, but it is processed first, so individual options may
+be enabled using 'enable-FEATURE'.
+
+   All of the following options except for 'alt-array-implementation',
+'disabled-builtins', 'direxpand-default', 'strict-posix-default', and
+'xpg-echo-default' are enabled by default, unless the operating system
+does not provide the necessary support.
+
+'--enable-alias'
+     Allow alias expansion and include the 'alias' and 'unalias'
+     builtins (*note Aliases::).
+
+'--enable-alt-array-implementation'
+     This builds bash using an alternate implementation of arrays (*note
+     Arrays::) that provides faster access at the expense of using more
+     memory (sometimes many times more, depending on how sparse an array
+     is).
+
+'--enable-arith-for-command'
+     Include support for the alternate form of the 'for' command that
+     behaves like the C language 'for' statement (*note Looping
+     Constructs::).
+
+'--enable-array-variables'
+     Include support for one-dimensional array shell variables (*note
+     Arrays::).
+
+'--enable-bang-history'
+     Include support for 'csh'-like history substitution (*note History
+     Interaction::).
+
+'--enable-brace-expansion'
+     Include 'csh'-like brace expansion ( 'b{a,b}c' ==> 'bac bbc' ).
+     See *note Brace Expansion::, for a complete description.
+
+'--enable-casemod-attributes'
+     Include support for case-modifying attributes in the 'declare'
+     builtin and assignment statements.  Variables with the 'uppercase'
+     attribute, for example, will have their values converted to
+     uppercase upon assignment.
+
+'--enable-casemod-expansion'
+     Include support for case-modifying word expansions.
+
+'--enable-command-timing'
+     Include support for recognizing 'time' as a reserved word and for
+     displaying timing statistics for the pipeline following 'time'
+     (*note Pipelines::).  This allows pipelines as well as shell
+     builtins and functions to be timed.
+
+'--enable-cond-command'
+     Include support for the '[[' conditional command.  (*note
+     Conditional Constructs::).
+
+'--enable-cond-regexp'
+     Include support for matching POSIX regular expressions using the
+     '=~' binary operator in the '[[' conditional command.  (*note
+     Conditional Constructs::).
+
+'--enable-coprocesses'
+     Include support for coprocesses and the 'coproc' reserved word
+     (*note Pipelines::).
+
+'--enable-debugger'
+     Include support for the bash debugger (distributed separately).
+
+'--enable-dev-fd-stat-broken'
+     If calling 'stat' on /dev/fd/N returns different results than
+     calling 'fstat' on file descriptor N, supply this option to enable
+     a workaround.  This has implications for conditional commands that
+     test file attributes.
+
+'--enable-direxpand-default'
+     Cause the 'direxpand' shell option (*note The Shopt Builtin::) to
+     be enabled by default when the shell starts.  It is normally
+     disabled by default.
+
+'--enable-directory-stack'
+     Include support for a 'csh'-like directory stack and the 'pushd',
+     'popd', and 'dirs' builtins (*note The Directory Stack::).
+
+'--enable-disabled-builtins'
+     Allow builtin commands to be invoked via 'builtin xxx' even after
+     'xxx' has been disabled using 'enable -n xxx'.  See *note Bash
+     Builtins::, for details of the 'builtin' and 'enable' builtin
+     commands.
+
+'--enable-dparen-arithmetic'
+     Include support for the '((...))' command (*note Conditional
+     Constructs::).
+
+'--enable-extended-glob'
+     Include support for the extended pattern matching features
+     described above under *note Pattern Matching::.
+
+'--enable-extended-glob-default'
+     Set the default value of the 'extglob' shell option described above
+     under *note The Shopt Builtin:: to be enabled.
+
+'--enable-function-import'
+     Include support for importing function definitions exported by
+     another instance of the shell from the environment.  This option is
+     enabled by default.
+
+'--enable-glob-asciirange-default'
+     Set the default value of the 'globasciiranges' shell option
+     described above under *note The Shopt Builtin:: to be enabled.
+     This controls the behavior of character ranges when used in pattern
+     matching bracket expressions.
+
+'--enable-help-builtin'
+     Include the 'help' builtin, which displays help on shell builtins
+     and variables (*note Bash Builtins::).
+
+'--enable-history'
+     Include command history and the 'fc' and 'history' builtin commands
+     (*note Bash History Facilities::).
+
+'--enable-job-control'
+     This enables the job control features (*note Job Control::), if the
+     operating system supports them.
+
+'--enable-multibyte'
+     This enables support for multibyte characters if the operating
+     system provides the necessary support.
+
+'--enable-net-redirections'
+     This enables the special handling of filenames of the form
+     '/dev/tcp/HOST/PORT' and '/dev/udp/HOST/PORT' when used in
+     redirections (*note Redirections::).
+
+'--enable-process-substitution'
+     This enables process substitution (*note Process Substitution::) if
+     the operating system provides the necessary support.
+
+'--enable-progcomp'
+     Enable the programmable completion facilities (*note Programmable
+     Completion::).  If Readline is not enabled, this option has no
+     effect.
+
+'--enable-prompt-string-decoding'
+     Turn on the interpretation of a number of backslash-escaped
+     characters in the '$PS0', '$PS1', '$PS2', and '$PS4' prompt
+     strings.  See *note Controlling the Prompt::, for a complete list
+     of prompt string escape sequences.
+
+'--enable-readline'
+     Include support for command-line editing and history with the Bash
+     version of the Readline library (*note Command Line Editing::).
+
+'--enable-restricted'
+     Include support for a "restricted shell".  If this is enabled,
+     Bash, when called as 'rbash', enters a restricted mode.  See *note
+     The Restricted Shell::, for a description of restricted mode.
+
+'--enable-select'
+     Include the 'select' compound command, which allows the generation
+     of simple menus (*note Conditional Constructs::).
+
+'--enable-single-help-strings'
+     Store the text displayed by the 'help' builtin as a single string
+     for each help topic.  This aids in translating the text to
+     different languages.  You may need to disable this if your compiler
+     cannot handle very long string literals.
+
+'--enable-strict-posix-default'
+     Make Bash POSIX-conformant by default (*note Bash POSIX Mode::).
+
+'--enable-translatable-strings'
+     Enable support for '$"STRING"' translatable strings (*note Locale
+     Translation::).
+
+'--enable-usg-echo-default'
+     A synonym for '--enable-xpg-echo-default'.
+
+'--enable-xpg-echo-default'
+     Make the 'echo' builtin expand backslash-escaped characters by
+     default, without requiring the '-e' option.  This sets the default
+     value of the 'xpg_echo' shell option to 'on', which makes the Bash
+     'echo' behave more like the version specified in the Single Unix
+     Specification, version 3.  *Note Bash Builtins::, for a description
+     of the escape sequences that 'echo' recognizes.
+
+   The file 'config-top.h' contains C Preprocessor '#define' statements
+for options which are not settable from 'configure'.  Some of these are
+not meant to be changed; beware of the consequences if you do.  Read the
+comments associated with each definition for more information about its
+effect.

+
+Appendix B Major Differences From The Bourne Shell
+**************************************************
+
+Bash implements essentially the same grammar, parameter and variable
+expansion, redirection, and quoting as the Bourne Shell.  Bash uses the
+POSIX standard as the specification of how these features are to be
+implemented.  There are some differences between the traditional Bourne
+shell and Bash; this section quickly details the differences of
+significance.  A number of these differences are explained in greater
+depth in previous sections.  This section uses the version of 'sh'
+included in SVR4.2 (the last version of the historical Bourne shell) as
+the baseline reference.
+
+   * Bash is POSIX-conformant, even where the POSIX specification
+     differs from traditional 'sh' behavior (*note Bash POSIX Mode::).
+
+   * Bash has multi-character invocation options (*note Invoking
+     Bash::).
+
+   * Bash has command-line editing (*note Command Line Editing::) and
+     the 'bind' builtin.
+
+   * Bash provides a programmable word completion mechanism (*note
+     Programmable Completion::), and builtin commands 'complete',
+     'compgen', and 'compopt', to manipulate it.
+
+   * Bash has command history (*note Bash History Facilities::) and the
+     'history' and 'fc' builtins to manipulate it.  The Bash history
+     list maintains timestamp information and uses the value of the
+     'HISTTIMEFORMAT' variable to display it.
+
+   * Bash implements 'csh'-like history expansion (*note History
+     Interaction::).
+
+   * Bash has one-dimensional array variables (*note Arrays::), and the
+     appropriate variable expansions and assignment syntax to use them.
+     Several of the Bash builtins take options to act on arrays.  Bash
+     provides a number of built-in array variables.
+
+   * The '$'...'' quoting syntax, which expands ANSI-C backslash-escaped
+     characters in the text between the single quotes, is supported
+     (*note ANSI-C Quoting::).
+
+   * Bash supports the '$"..."' quoting syntax to do locale-specific
+     translation of the characters between the double quotes.  The '-D',
+     '--dump-strings', and '--dump-po-strings' invocation options list
+     the translatable strings found in a script (*note Locale
+     Translation::).
+
+   * Bash implements the '!' keyword to negate the return value of a
+     pipeline (*note Pipelines::).  Very useful when an 'if' statement
+     needs to act only if a test fails.  The Bash '-o pipefail' option
+     to 'set' will cause a pipeline to return a failure status if any
+     command fails.
+
+   * Bash has the 'time' reserved word and command timing (*note
+     Pipelines::).  The display of the timing statistics may be
+     controlled with the 'TIMEFORMAT' variable.
+
+   * Bash implements the 'for (( EXPR1 ; EXPR2 ; EXPR3 ))' arithmetic
+     for command, similar to the C language (*note Looping
+     Constructs::).
+
+   * Bash includes the 'select' compound command, which allows the
+     generation of simple menus (*note Conditional Constructs::).
+
+   * Bash includes the '[[' compound command, which makes conditional
+     testing part of the shell grammar (*note Conditional Constructs::),
+     including optional regular expression matching.
+
+   * Bash provides optional case-insensitive matching for the 'case' and
+     '[[' constructs.
+
+   * Bash includes brace expansion (*note Brace Expansion::) and tilde
+     expansion (*note Tilde Expansion::).
+
+   * Bash implements command aliases and the 'alias' and 'unalias'
+     builtins (*note Aliases::).
+
+   * Bash provides shell arithmetic, the '((' compound command (*note
+     Conditional Constructs::), and arithmetic expansion (*note Shell
+     Arithmetic::).
+
+   * Variables present in the shell's initial environment are
+     automatically exported to child processes.  The Bourne shell does
+     not normally do this unless the variables are explicitly marked
+     using the 'export' command.
+
+   * Bash supports the '+=' assignment operator, which appends to the
+     value of the variable named on the left hand side.
+
+   * Bash includes the POSIX pattern removal '%', '#', '%%' and '##'
+     expansions to remove leading or trailing substrings from variable
+     values (*note Shell Parameter Expansion::).
+
+   * The expansion '${#xx}', which returns the length of '${xx}', is
+     supported (*note Shell Parameter Expansion::).
+
+   * The expansion '${var:'OFFSET'[:'LENGTH']}', which expands to the
+     substring of 'var''s value of length LENGTH, beginning at OFFSET,
+     is present (*note Shell Parameter Expansion::).
+
+   * The expansion '${VAR/[/]'PATTERN'[/'REPLACEMENT']}', which matches
+     PATTERN and replaces it with REPLACEMENT in the value of VAR, is
+     available (*note Shell Parameter Expansion::).
+
+   * The expansion '${!PREFIX*}' expansion, which expands to the names
+     of all shell variables whose names begin with PREFIX, is available
+     (*note Shell Parameter Expansion::).
+
+   * Bash has indirect variable expansion using '${!word}' (*note Shell
+     Parameter Expansion::).
+
+   * Bash can expand positional parameters beyond '$9' using '${NUM}'.
+
+   * The POSIX '$()' form of command substitution is implemented (*note
+     Command Substitution::), and preferred to the Bourne shell's '``'
+     (which is also implemented for backwards compatibility).
+
+   * Bash has process substitution (*note Process Substitution::).
+
+   * Bash automatically assigns variables that provide information about
+     the current user ('UID', 'EUID', and 'GROUPS'), the current host
+     ('HOSTTYPE', 'OSTYPE', 'MACHTYPE', and 'HOSTNAME'), and the
+     instance of Bash that is running ('BASH', 'BASH_VERSION', and
+     'BASH_VERSINFO').  *Note Bash Variables::, for details.
+
+   * The 'IFS' variable is used to split only the results of expansion,
+     not all words (*note Word Splitting::).  This closes a longstanding
+     shell security hole.
+
+   * The filename expansion bracket expression code uses '!' and '^' to
+     negate the set of characters between the brackets.  The Bourne
+     shell uses only '!'.
+
+   * Bash implements the full set of POSIX filename expansion operators,
+     including character classes, equivalence classes, and collating
+     symbols (*note Filename Expansion::).
+
+   * Bash implements extended pattern matching features when the
+     'extglob' shell option is enabled (*note Pattern Matching::).
+
+   * It is possible to have a variable and a function with the same
+     name; 'sh' does not separate the two name spaces.
+
+   * Bash functions are permitted to have local variables using the
+     'local' builtin, and thus useful recursive functions may be written
+     (*note Bash Builtins::).
+
+   * Variable assignments preceding commands affect only that command,
+     even builtins and functions (*note Environment::).  In 'sh', all
+     variable assignments preceding commands are global unless the
+     command is executed from the file system.
+
+   * Bash performs filename expansion on filenames specified as operands
+     to input and output redirection operators (*note Redirections::).
+
+   * Bash contains the '<>' redirection operator, allowing a file to be
+     opened for both reading and writing, and the '&>' redirection
+     operator, for directing standard output and standard error to the
+     same file (*note Redirections::).
+
+   * Bash includes the '<<<' redirection operator, allowing a string to
+     be used as the standard input to a command.
+
+   * Bash implements the '[n]<&WORD' and '[n]>&WORD' redirection
+     operators, which move one file descriptor to another.
+
+   * Bash treats a number of filenames specially when they are used in
+     redirection operators (*note Redirections::).
+
+   * Bash can open network connections to arbitrary machines and
+     services with the redirection operators (*note Redirections::).
+
+   * The 'noclobber' option is available to avoid overwriting existing
+     files with output redirection (*note The Set Builtin::).  The '>|'
+     redirection operator may be used to override 'noclobber'.
+
+   * The Bash 'cd' and 'pwd' builtins (*note Bourne Shell Builtins::)
+     each take '-L' and '-P' options to switch between logical and
+     physical modes.
+
+   * Bash allows a function to override a builtin with the same name,
+     and provides access to that builtin's functionality within the
+     function via the 'builtin' and 'command' builtins (*note Bash
+     Builtins::).
+
+   * The 'command' builtin allows selective disabling of functions when
+     command lookup is performed (*note Bash Builtins::).
+
+   * Individual builtins may be enabled or disabled using the 'enable'
+     builtin (*note Bash Builtins::).
+
+   * The Bash 'exec' builtin takes additional options that allow users
+     to control the contents of the environment passed to the executed
+     command, and what the zeroth argument to the command is to be
+     (*note Bourne Shell Builtins::).
+
+   * Shell functions may be exported to children via the environment
+     using 'export -f' (*note Shell Functions::).
+
+   * The Bash 'export', 'readonly', and 'declare' builtins can take a
+     '-f' option to act on shell functions, a '-p' option to display
+     variables with various attributes set in a format that can be used
+     as shell input, a '-n' option to remove various variable
+     attributes, and 'name=value' arguments to set variable attributes
+     and values simultaneously.
+
+   * The Bash 'hash' builtin allows a name to be associated with an
+     arbitrary filename, even when that filename cannot be found by
+     searching the '$PATH', using 'hash -p' (*note Bourne Shell
+     Builtins::).
+
+   * Bash includes a 'help' builtin for quick reference to shell
+     facilities (*note Bash Builtins::).
+
+   * The 'printf' builtin is available to display formatted output
+     (*note Bash Builtins::).
+
+   * The Bash 'read' builtin (*note Bash Builtins::) will read a line
+     ending in '\' with the '-r' option, and will use the 'REPLY'
+     variable as a default if no non-option arguments are supplied.  The
+     Bash 'read' builtin also accepts a prompt string with the '-p'
+     option and will use Readline to obtain the line when given the '-e'
+     option.  The 'read' builtin also has additional options to control
+     input: the '-s' option will turn off echoing of input characters as
+     they are read, the '-t' option will allow 'read' to time out if
+     input does not arrive within a specified number of seconds, the
+     '-n' option will allow reading only a specified number of
+     characters rather than a full line, and the '-d' option will read
+     until a particular character rather than newline.
+
+   * The 'return' builtin may be used to abort execution of scripts
+     executed with the '.' or 'source' builtins (*note Bourne Shell
+     Builtins::).
+
+   * Bash includes the 'shopt' builtin, for finer control of shell
+     optional capabilities (*note The Shopt Builtin::), and allows these
+     options to be set and unset at shell invocation (*note Invoking
+     Bash::).
+
+   * Bash has much more optional behavior controllable with the 'set'
+     builtin (*note The Set Builtin::).
+
+   * The '-x' ('xtrace') option displays commands other than simple
+     commands when performing an execution trace (*note The Set
+     Builtin::).
+
+   * The 'test' builtin (*note Bourne Shell Builtins::) is slightly
+     different, as it implements the POSIX algorithm, which specifies
+     the behavior based on the number of arguments.
+
+   * Bash includes the 'caller' builtin, which displays the context of
+     any active subroutine call (a shell function or a script executed
+     with the '.' or 'source' builtins).  This supports the Bash
+     debugger.
+
+   * The 'trap' builtin (*note Bourne Shell Builtins::) allows a 'DEBUG'
+     pseudo-signal specification, similar to 'EXIT'.  Commands specified
+     with a 'DEBUG' trap are executed before every simple command, 'for'
+     command, 'case' command, 'select' command, every arithmetic 'for'
+     command, and before the first command executes in a shell function.
+     The 'DEBUG' trap is not inherited by shell functions unless the
+     function has been given the 'trace' attribute or the 'functrace'
+     option has been enabled using the 'shopt' builtin.  The 'extdebug'
+     shell option has additional effects on the 'DEBUG' trap.
+
+     The 'trap' builtin (*note Bourne Shell Builtins::) allows an 'ERR'
+     pseudo-signal specification, similar to 'EXIT' and 'DEBUG'.
+     Commands specified with an 'ERR' trap are executed after a simple
+     command fails, with a few exceptions.  The 'ERR' trap is not
+     inherited by shell functions unless the '-o errtrace' option to the
+     'set' builtin is enabled.
+
+     The 'trap' builtin (*note Bourne Shell Builtins::) allows a
+     'RETURN' pseudo-signal specification, similar to 'EXIT' and
+     'DEBUG'.  Commands specified with a 'RETURN' trap are executed
+     before execution resumes after a shell function or a shell script
+     executed with '.' or 'source' returns.  The 'RETURN' trap is not
+     inherited by shell functions unless the function has been given the
+     'trace' attribute or the 'functrace' option has been enabled using
+     the 'shopt' builtin.
+
+   * The Bash 'type' builtin is more extensive and gives more
+     information about the names it finds (*note Bash Builtins::).
+
+   * The Bash 'umask' builtin permits a '-p' option to cause the output
+     to be displayed in the form of a 'umask' command that may be reused
+     as input (*note Bourne Shell Builtins::).
+
+   * Bash implements a 'csh'-like directory stack, and provides the
+     'pushd', 'popd', and 'dirs' builtins to manipulate it (*note The
+     Directory Stack::).  Bash also makes the directory stack visible as
+     the value of the 'DIRSTACK' shell variable.
+
+   * Bash interprets special backslash-escaped characters in the prompt
+     strings when interactive (*note Controlling the Prompt::).
+
+   * The Bash restricted mode is more useful (*note The Restricted
+     Shell::); the SVR4.2 shell restricted mode is too limited.
+
+   * The 'disown' builtin can remove a job from the internal shell job
+     table (*note Job Control Builtins::) or suppress the sending of
+     'SIGHUP' to a job when the shell exits as the result of a 'SIGHUP'.
+
+   * Bash includes a number of features to support a separate debugger
+     for shell scripts.
+
+   * The SVR4.2 shell has two privilege-related builtins ('mldmode' and
+     'priv') not present in Bash.
+
+   * Bash does not have the 'stop' or 'newgrp' builtins.
+
+   * Bash does not use the 'SHACCT' variable or perform shell
+     accounting.
+
+   * The SVR4.2 'sh' uses a 'TIMEOUT' variable like Bash uses 'TMOUT'.
+
+More features unique to Bash may be found in *note Bash Features::.
+
+B.1 Implementation Differences From The SVR4.2 Shell
+====================================================
+
+Since Bash is a completely new implementation, it does not suffer from
+many of the limitations of the SVR4.2 shell.  For instance:
+
+   * Bash does not fork a subshell when redirecting into or out of a
+     shell control structure such as an 'if' or 'while' statement.
+
+   * Bash does not allow unbalanced quotes.  The SVR4.2 shell will
+     silently insert a needed closing quote at 'EOF' under certain
+     circumstances.  This can be the cause of some hard-to-find errors.
+
+   * The SVR4.2 shell uses a baroque memory management scheme based on
+     trapping 'SIGSEGV'.  If the shell is started from a process with
+     'SIGSEGV' blocked (e.g., by using the 'system()' C library function
+     call), it misbehaves badly.
+
+   * In a questionable attempt at security, the SVR4.2 shell, when
+     invoked without the '-p' option, will alter its real and effective
+     UID and GID if they are less than some magic threshold value,
+     commonly 100.  This can lead to unexpected results.
+
+   * The SVR4.2 shell does not allow users to trap 'SIGSEGV', 'SIGALRM',
+     or 'SIGCHLD'.
+
+   * The SVR4.2 shell does not allow the 'IFS', 'MAILCHECK', 'PATH',
+     'PS1', or 'PS2' variables to be unset.
+
+   * The SVR4.2 shell treats '^' as the undocumented equivalent of '|'.
+
+   * Bash allows multiple option arguments when it is invoked ('-x -v');
+     the SVR4.2 shell allows only one option argument ('-xv').  In fact,
+     some versions of the shell dump core if the second argument begins
+     with a '-'.
+
+   * The SVR4.2 shell exits a script if any builtin fails; Bash exits a
+     script only if one of the POSIX special builtins fails, and only
+     for certain failures, as enumerated in the POSIX standard.
+
+   * The SVR4.2 shell behaves differently when invoked as 'jsh' (it
+     turns on job control).

+
+     Everyone is permitted to copy and distribute verbatim copies
+     of this license document, but changing it is not allowed.
+
+  0. PREAMBLE
+
+     The purpose of this License is to make a manual, textbook, or other
+     functional and useful document "free" in the sense of freedom: to
+     assure everyone the effective freedom to copy and redistribute it,
+     with or without modifying it, either commercially or
+     noncommercially.  Secondarily, this License preserves for the
+     author and publisher a way to get credit for their work, while not
+     being considered responsible for modifications made by others.
+
+     This License is a kind of "copyleft", which means that derivative
+     works of the document must themselves be free in the same sense.
+     It complements the GNU General Public License, which is a copyleft
+     license designed for free software.
+
+     We have designed this License in order to use it for manuals for
+     free software, because free software needs free documentation: a
+     free program should come with manuals providing the same freedoms
+     that the software does.  But this License is not limited to
+     software manuals; it can be used for any textual work, regardless
+     of subject matter or whether it is published as a printed book.  We
+     recommend this License principally for works whose purpose is
+     instruction or reference.
+
+  1. APPLICABILITY AND DEFINITIONS
+
+     This License applies to any manual or other work, in any medium,
+     that contains a notice placed by the copyright holder saying it can
+     be distributed under the terms of this License.  Such a notice
+     grants a world-wide, royalty-free license, unlimited in duration,
+     to use that work under the conditions stated herein.  The
+     "Document", below, refers to any such manual or work.  Any member
+     of the public is a licensee, and is addressed as "you".  You accept
+     the license if you copy, modify or distribute the work in a way
+     requiring permission under copyright law.
+
+     A "Modified Version" of the Document means any work containing the
+     Document or a portion of it, either copied verbatim, or with
+     modifications and/or translated into another language.
+
+     A "Secondary Section" is a named appendix or a front-matter section
+     of the Document that deals exclusively with the relationship of the
+     publishers or authors of the Document to the Document's overall
+     subject (or to related matters) and contains nothing that could
+     fall directly within that overall subject.  (Thus, if the Document
+     is in part a textbook of mathematics, a Secondary Section may not
+     explain any mathematics.)  The relationship could be a matter of
+     historical connection with the subject or with related matters, or
+     of legal, commercial, philosophical, ethical or political position
+     regarding them.
+
+     The "Invariant Sections" are certain Secondary Sections whose
+     titles are designated, as being those of Invariant Sections, in the
+     notice that says that the Document is released under this License.
+     If a section does not fit the above definition of Secondary then it
+     is not allowed to be designated as Invariant.  The Document may
+     contain zero Invariant Sections.  If the Document does not identify
+     any Invariant Sections then there are none.
+
+     The "Cover Texts" are certain short passages of text that are
+     listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+     that says that the Document is released under this License.  A
+     Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+     be at most 25 words.
+
+     A "Transparent" copy of the Document means a machine-readable copy,
+     represented in a format whose specification is available to the
+     general public, that is suitable for revising the document
+     straightforwardly with generic text editors or (for images composed
+     of pixels) generic paint programs or (for drawings) some widely
+     available drawing editor, and that is suitable for input to text
+     formatters or for automatic translation to a variety of formats
+     suitable for input to text formatters.  A copy made in an otherwise
+     Transparent file format whose markup, or absence of markup, has
+     been arranged to thwart or discourage subsequent modification by
+     readers is not Transparent.  An image format is not Transparent if
+     used for any substantial amount of text.  A copy that is not
+     "Transparent" is called "Opaque".
+
+     Examples of suitable formats for Transparent copies include plain
+     ASCII without markup, Texinfo input format, LaTeX input format,
+     SGML or XML using a publicly available DTD, and standard-conforming
+     simple HTML, PostScript or PDF designed for human modification.
+     Examples of transparent image formats include PNG, XCF and JPG.
+     Opaque formats include proprietary formats that can be read and
+     edited only by proprietary word processors, SGML or XML for which
+     the DTD and/or processing tools are not generally available, and
+     the machine-generated HTML, PostScript or PDF produced by some word
+     processors for output purposes only.
+
+     The "Title Page" means, for a printed book, the title page itself,
+     plus such following pages as are needed to hold, legibly, the
+     material this License requires to appear in the title page.  For
+     works in formats which do not have any title page as such, "Title
+     Page" means the text near the most prominent appearance of the
+     work's title, preceding the beginning of the body of the text.
+
+     The "publisher" means any person or entity that distributes copies
+     of the Document to the public.
+
+     A section "Entitled XYZ" means a named subunit of the Document
+     whose title either is precisely XYZ or contains XYZ in parentheses
+     following text that translates XYZ in another language.  (Here XYZ
+     stands for a specific section name mentioned below, such as
+     "Acknowledgements", "Dedications", "Endorsements", or "History".)
+     To "Preserve the Title" of such a section when you modify the
+     Document means that it remains a section "Entitled XYZ" according
+     to this definition.
+
+     The Document may include Warranty Disclaimers next to the notice
+     which states that this License applies to the Document.  These
+     Warranty Disclaimers are considered to be included by reference in
+     this License, but only as regards disclaiming warranties: any other
+     implication that these Warranty Disclaimers may have is void and
+     has no effect on the meaning of this License.
+
+  2. VERBATIM COPYING
+
+     You may copy and distribute the Document in any medium, either
+     commercially or noncommercially, provided that this License, the
+     copyright notices, and the license notice saying this License
+     applies to the Document are reproduced in all copies, and that you
+     add no other conditions whatsoever to those of this License.  You
+     may not use technical measures to obstruct or control the reading
+     or further copying of the copies you make or distribute.  However,
+     you may accept compensation in exchange for copies.  If you
+     distribute a large enough number of copies you must also follow the
+     conditions in section 3.
+
+     You may also lend copies, under the same conditions stated above,
+     and you may publicly display copies.
+
+  3. COPYING IN QUANTITY
+
+     If you publish printed copies (or copies in media that commonly
+     have printed covers) of the Document, numbering more than 100, and
+     the Document's license notice requires Cover Texts, you must
+     enclose the copies in covers that carry, clearly and legibly, all
+     these Cover Texts: Front-Cover Texts on the front cover, and
+     Back-Cover Texts on the back cover.  Both covers must also clearly
+     and legibly identify you as the publisher of these copies.  The
+     front cover must present the full title with all words of the title
+     equally prominent and visible.  You may add other material on the
+     covers in addition.  Copying with changes limited to the covers, as
+     long as they preserve the title of the Document and satisfy these
+     conditions, can be treated as verbatim copying in other respects.
+
+     If the required texts for either cover are too voluminous to fit
+     legibly, you should put the first ones listed (as many as fit
+     reasonably) on the actual cover, and continue the rest onto
+     adjacent pages.
+
+     If you publish or distribute Opaque copies of the Document
+     numbering more than 100, you must either include a machine-readable
+     Transparent copy along with each Opaque copy, or state in or with
+     each Opaque copy a computer-network location from which the general
+     network-using public has access to download using public-standard
+     network protocols a complete Transparent copy of the Document, free
+     of added material.  If you use the latter option, you must take
+     reasonably prudent steps, when you begin distribution of Opaque
+     copies in quantity, to ensure that this Transparent copy will
+     remain thus accessible at the stated location until at least one
+     year after the last time you distribute an Opaque copy (directly or
+     through your agents or retailers) of that edition to the public.
+
+     It is requested, but not required, that you contact the authors of
+     the Document well before redistributing any large number of copies,
+     to give them a chance to provide you with an updated version of the
+     Document.
+
+  4. MODIFICATIONS
+
+     You may copy and distribute a Modified Version of the Document
+     under the conditions of sections 2 and 3 above, provided that you
+     release the Modified Version under precisely this License, with the
+     Modified Version filling the role of the Document, thus licensing
+     distribution and modification of the Modified Version to whoever
+     possesses a copy of it.  In addition, you must do these things in
+     the Modified Version:
+
+       A. Use in the Title Page (and on the covers, if any) a title
+          distinct from that of the Document, and from those of previous
+          versions (which should, if there were any, be listed in the
+          History section of the Document).  You may use the same title
+          as a previous version if the original publisher of that
+          version gives permission.
+
+       B. List on the Title Page, as authors, one or more persons or
+          entities responsible for authorship of the modifications in
+          the Modified Version, together with at least five of the
+          principal authors of the Document (all of its principal
+          authors, if it has fewer than five), unless they release you
+          from this requirement.
+
+       C. State on the Title page the name of the publisher of the
+          Modified Version, as the publisher.
+
+       D. Preserve all the copyright notices of the Document.
+
+       E. Add an appropriate copyright notice for your modifications
+          adjacent to the other copyright notices.
+
+       F. Include, immediately after the copyright notices, a license
+          notice giving the public permission to use the Modified
+          Version under the terms of this License, in the form shown in
+          the Addendum below.
+
+       G. Preserve in that license notice the full lists of Invariant
+          Sections and required Cover Texts given in the Document's
+          license notice.
+
+       H. Include an unaltered copy of this License.
+
+       I. Preserve the section Entitled "History", Preserve its Title,
+          and add to it an item stating at least the title, year, new
+          authors, and publisher of the Modified Version as given on the
+          Title Page.  If there is no section Entitled "History" in the
+          Document, create one stating the title, year, authors, and
+          publisher of the Document as given on its Title Page, then add
+          an item describing the Modified Version as stated in the
+          previous sentence.
+
+       J. Preserve the network location, if any, given in the Document
+          for public access to a Transparent copy of the Document, and
+          likewise the network locations given in the Document for
+          previous versions it was based on.  These may be placed in the
+          "History" section.  You may omit a network location for a work
+          that was published at least four years before the Document
+          itself, or if the original publisher of the version it refers
+          to gives permission.
+
+       K. For any section Entitled "Acknowledgements" or "Dedications",
+          Preserve the Title of the section, and preserve in the section
+          all the substance and tone of each of the contributor
+          acknowledgements and/or dedications given therein.
+
+       L. Preserve all the Invariant Sections of the Document, unaltered
+          in their text and in their titles.  Section numbers or the
+          equivalent are not considered part of the section titles.
+
+       M. Delete any section Entitled "Endorsements".  Such a section
+          may not be included in the Modified Version.
+
+       N. Do not retitle any existing section to be Entitled
+          "Endorsements" or to conflict in title with any Invariant
+          Section.
+
+       O. Preserve any Warranty Disclaimers.
+
+     If the Modified Version includes new front-matter sections or
+     appendices that qualify as Secondary Sections and contain no
+     material copied from the Document, you may at your option designate
+     some or all of these sections as invariant.  To do this, add their
+     titles to the list of Invariant Sections in the Modified Version's
+     license notice.  These titles must be distinct from any other
+     section titles.
+
+     You may add a section Entitled "Endorsements", provided it contains
+     nothing but endorsements of your Modified Version by various
+     parties--for example, statements of peer review or that the text
+     has been approved by an organization as the authoritative
+     definition of a standard.
+
+     You may add a passage of up to five words as a Front-Cover Text,
+     and a passage of up to 25 words as a Back-Cover Text, to the end of
+     the list of Cover Texts in the Modified Version.  Only one passage
+     of Front-Cover Text and one of Back-Cover Text may be added by (or
+     through arrangements made by) any one entity.  If the Document
+     already includes a cover text for the same cover, previously added
+     by you or by arrangement made by the same entity you are acting on
+     behalf of, you may not add another; but you may replace the old
+     one, on explicit permission from the previous publisher that added
+     the old one.
+
+     The author(s) and publisher(s) of the Document do not by this
+     License give permission to use their names for publicity for or to
+     assert or imply endorsement of any Modified Version.
+
+  5. COMBINING DOCUMENTS
+
+     You may combine the Document with other documents released under
+     this License, under the terms defined in section 4 above for
+     modified versions, provided that you include in the combination all
+     of the Invariant Sections of all of the original documents,
+     unmodified, and list them all as Invariant Sections of your
+     combined work in its license notice, and that you preserve all
+     their Warranty Disclaimers.
+
+     The combined work need only contain one copy of this License, and
+     multiple identical Invariant Sections may be replaced with a single
+     copy.  If there are multiple Invariant Sections with the same name
+     but different contents, make the title of each such section unique
+     by adding at the end of it, in parentheses, the name of the
+     original author or publisher of that section if known, or else a
+     unique number.  Make the same adjustment to the section titles in
+     the list of Invariant Sections in the license notice of the
+     combined work.
+
+     In the combination, you must combine any sections Entitled
+     "History" in the various original documents, forming one section
+     Entitled "History"; likewise combine any sections Entitled
+     "Acknowledgements", and any sections Entitled "Dedications".  You
+     must delete all sections Entitled "Endorsements."
+
+  6. COLLECTIONS OF DOCUMENTS
+
+     You may make a collection consisting of the Document and other
+     documents released under this License, and replace the individual
+     copies of this License in the various documents with a single copy
+     that is included in the collection, provided that you follow the
+     rules of this License for verbatim copying of each of the documents
+     in all other respects.
+
+     You may extract a single document from such a collection, and
+     distribute it individually under this License, provided you insert
+     a copy of this License into the extracted document, and follow this
+     License in all other respects regarding verbatim copying of that
+     document.
+
+  7. AGGREGATION WITH INDEPENDENT WORKS
+
+     A compilation of the Document or its derivatives with other
+     separate and independent documents or works, in or on a volume of a
+     storage or distribution medium, is called an "aggregate" if the
+     copyright resulting from the compilation is not used to limit the
+     legal rights of the compilation's users beyond what the individual
+     works permit.  When the Document is included in an aggregate, this
+     License does not apply to the other works in the aggregate which
+     are not themselves derivative works of the Document.
+
+     If the Cover Text requirement of section 3 is applicable to these
+     copies of the Document, then if the Document is less than one half
+     of the entire aggregate, the Document's Cover Texts may be placed
+     on covers that bracket the Document within the aggregate, or the
+     electronic equivalent of covers if the Document is in electronic
+     form.  Otherwise they must appear on printed covers that bracket
+     the whole aggregate.
+
+  8. TRANSLATION
+
+     Translation is considered a kind of modification, so you may
+     distribute translations of the Document under the terms of section
+     4.  Replacing Invariant Sections with translations requires special
+     permission from their copyright holders, but you may include
+     translations of some or all Invariant Sections in addition to the
+     original versions of these Invariant Sections.  You may include a
+     translation of this License, and all the license notices in the
+     Document, and any Warranty Disclaimers, provided that you also
+     include the original English version of this License and the
+     original versions of those notices and disclaimers.  In case of a
+     disagreement between the translation and the original version of
+     this License or a notice or disclaimer, the original version will
+     prevail.
+
+     If a section in the Document is Entitled "Acknowledgements",
+     "Dedications", or "History", the requirement (section 4) to
+     Preserve its Title (section 1) will typically require changing the
+     actual title.
+
+  9. TERMINATION
+
+     You may not copy, modify, sublicense, or distribute the Document
+     except as expressly provided under this License.  Any attempt
+     otherwise to copy, modify, sublicense, or distribute it is void,
+     and will automatically terminate your rights under this License.
+
+     However, if you cease all violation of this License, then your
+     license from a particular copyright holder is reinstated (a)
+     provisionally, unless and until the copyright holder explicitly and
+     finally terminates your license, and (b) permanently, if the
+     copyright holder fails to notify you of the violation by some
+     reasonable means prior to 60 days after the cessation.
+
+     Moreover, your license from a particular copyright holder is
+     reinstated permanently if the copyright holder notifies you of the
+     violation by some reasonable means, this is the first time you have
+     received notice of violation of this License (for any work) from
+     that copyright holder, and you cure the violation prior to 30 days
+     after your receipt of the notice.
+
+     Termination of your rights under this section does not terminate
+     the licenses of parties who have received copies or rights from you
+     under this License.  If your rights have been terminated and not
+     permanently reinstated, receipt of a copy of some or all of the
+     same material does not give you any rights to use it.
+
+  10. FUTURE REVISIONS OF THIS LICENSE
+
+     The Free Software Foundation may publish new, revised versions of
+     the GNU Free Documentation License from time to time.  Such new
+     versions will be similar in spirit to the present version, but may
+     differ in detail to address new problems or concerns.  See
+     <http://www.gnu.org/copyleft/>.
+
+     Each version of the License is given a distinguishing version
+     number.  If the Document specifies that a particular numbered
+     version of this License "or any later version" applies to it, you
+     have the option of following the terms and conditions either of
+     that specified version or of any later version that has been
+     published (not as a draft) by the Free Software Foundation.  If the
+     Document does not specify a version number of this License, you may
+     choose any version ever published (not as a draft) by the Free
+     Software Foundation.  If the Document specifies that a proxy can
+     decide which future versions of this License can be used, that
+     proxy's public statement of acceptance of a version permanently
+     authorizes you to choose that version for the Document.
+
+  11. RELICENSING
+
+     "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+     World Wide Web server that publishes copyrightable works and also
+     provides prominent facilities for anybody to edit those works.  A
+     public wiki that anybody can edit is an example of such a server.
+     A "Massive Multiauthor Collaboration" (or "MMC") contained in the
+     site means any set of copyrightable works thus published on the MMC
+     site.
+
+     "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+     license published by Creative Commons Corporation, a not-for-profit
+     corporation with a principal place of business in San Francisco,
+     California, as well as future copyleft versions of that license
+     published by that same organization.
+
+     "Incorporate" means to publish or republish a Document, in whole or
+     in part, as part of another Document.
+
+     An MMC is "eligible for relicensing" if it is licensed under this
+     License, and if all works that were first published under this
+     License somewhere other than this MMC, and subsequently
+     incorporated in whole or in part into the MMC, (1) had no cover
+     texts or invariant sections, and (2) were thus incorporated prior
+     to November 1, 2008.
+
+     The operator of an MMC Site may republish an MMC contained in the
+     site under CC-BY-SA on the same site at any time before August 1,
+     2009, provided the MMC is eligible for relicensing.
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+       Copyright (C)  YEAR  YOUR NAME.
+       Permission is granted to copy, distribute and/or modify this document
+       under the terms of the GNU Free Documentation License, Version 1.3
+       or any later version published by the Free Software Foundation;
+       with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+       Texts.  A copy of the license is included in the section entitled ``GNU
+       Free Documentation License''.
+
+   If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts."  line with this:
+
+         with the Invariant Sections being LIST THEIR TITLES, with
+         the Front-Cover Texts being LIST, and with the Back-Cover Texts
+         being LIST.
+
+   If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+   If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of free
+software license, such as the GNU General Public License, to permit
+their use in free software.

+@section What is Bash?
+
+Bash is the shell, or command language interpreter,
+for the @sc{gnu} operating system.
+The name is an acronym for the @samp{Bourne-Again SHell},
+a pun on Stephen Bourne, the author of the direct ancestor of
+the current Unix shell @code{sh}, 
+which appeared in the Seventh Edition Bell Labs Research version
+of Unix.
+
+Bash is largely compatible with @code{sh} and incorporates useful
+features from the Korn shell @code{ksh} and the C shell @code{csh}.
+It is intended to be a conformant implementation of the @sc{ieee}
+@sc{posix} Shell and Tools portion of the @sc{ieee} @sc{posix}
+specification (@sc{ieee} Standard 1003.1).
+It offers functional improvements over @code{sh} for both interactive and
+programming use.
+
+While the @sc{gnu} operating system provides other shells, including
+a version of @code{csh}, Bash is the default shell.
+Like other @sc{gnu} software, Bash is quite portable.  It currently runs
+on nearly every version of Unix and a few other operating systems @minus{}
+independently-supported ports exist for @sc{ms-dos}, @sc{os/2},
+and Windows platforms.
+
+@node What is a shell?
+@section What is a shell?
+
+At its base, a shell is simply a macro processor that executes
+commands.  The term macro processor means functionality where text
+and symbols are expanded to create larger expressions.
+
+A Unix shell is both a command interpreter and a programming
+language.  As a command interpreter, the shell provides the user
+interface to the rich set of @sc{gnu} utilities.  The programming
+language features allow these utilities to be combined.
+Files containing commands can be created, and become
+commands themselves.  These new commands have the same status as
+system commands in directories such as @file{/bin}, allowing users
+or groups to establish custom environments to automate their common
+tasks.
+
+Shells may be used interactively or non-interactively.  In
+interactive mode, they accept input typed from the keyboard.
+When executing non-interactively, shells execute commands read
+from a file.
+
+A shell allows execution of @sc{gnu} commands, both synchronously and
+asynchronously.
+The shell waits for synchronous commands to complete before accepting
+more input; asynchronous commands continue to execute in parallel
+with the shell while it reads and executes additional commands.
+The @dfn{redirection} constructs permit
+fine-grained control of the input and output of those commands.
+Moreover, the shell allows control over the contents of commands'
+environments.
+
+Shells also provide a small set of built-in
+commands (@dfn{builtins}) implementing functionality impossible
+or inconvenient to obtain via separate utilities.
+For example, @code{cd}, @code{break}, @code{continue}, and
+@code{exec} cannot be implemented outside of the shell because
+they directly manipulate the shell itself.
+The @code{history}, @code{getopts}, @code{kill}, or @code{pwd}
+builtins, among others, could be implemented in separate utilities,
+but they are more convenient to use as builtin commands.
+All of the shell builtins are described in
+subsequent sections.
+
+While executing commands is essential, most of the power (and
+complexity) of shells is due to their embedded programming
+languages.  Like any high-level language, the shell provides
+variables, flow control constructs, quoting, and functions. 
+
+Shells offer features geared specifically for
+interactive use rather than to augment the programming language. 
+These interactive features include job control, command line
+editing, command history and aliases.  Each of these features is
+described in this manual.

+@cindex Bourne shell
+
+Bash is an acronym for @samp{Bourne-Again SHell}.
+The Bourne shell is
+the traditional Unix shell originally written by Stephen Bourne.
+All of the Bourne shell builtin commands are available in Bash,
+The rules for evaluation and quoting are taken from the @sc{posix}
+specification for the `standard' Unix shell.
+
+This chapter briefly summarizes the shell's `building blocks':
+commands, control structures, shell functions, shell @i{parameters},
+shell expansions,
+@i{redirections}, which are a way to direct input and output from
+and to named files, and how the shell executes commands.

+@end menu
+
+When the shell reads input, it proceeds through a
+sequence of operations.  If the input indicates the beginning of a
+comment, the shell ignores the comment symbol (@samp{#}), and the rest
+of that line.
+                                
+Otherwise, roughly speaking,  the shell reads its input and
+divides the input into words and operators, employing the quoting rules
+to select which meanings to assign various words and characters.
+
+The shell then parses these tokens into commands and other constructs,
+removes the special meaning of certain words or characters, expands
+others, redirects input and output as needed, executes the specified
+command, waits for the command's exit status, and makes that exit status
+available for further inspection or processing.
+
+@node Shell Operation
+@subsection Shell Operation
+
+The following is a brief description of the shell's operation when it
+reads and executes a command.  Basically, the shell does the
+following:
+
+@enumerate
+@item
+Reads its input from a file (@pxref{Shell Scripts}), from a string
+supplied as an argument to the @option{-c} invocation option
+(@pxref{Invoking Bash}), or from the user's terminal.
+
+@item
+Breaks the input into words and operators, obeying the quoting rules
+described in @ref{Quoting}.  These tokens are separated by
+@code{metacharacters}.  Alias expansion is performed by this step
+(@pxref{Aliases}).
+
+@item
+Parses the tokens into simple and compound commands
+(@pxref{Shell Commands}).
+
+@item
+Performs the various shell expansions (@pxref{Shell Expansions}), breaking
+the expanded tokens into lists of filenames (@pxref{Filename Expansion})
+and commands and arguments.
+
+@item
+Performs any necessary redirections (@pxref{Redirections}) and removes
+the redirection operators and their operands from the argument list.
+
+@item
+Executes the command (@pxref{Executing Commands}).
+
+@item
+Optionally waits for the command to complete and collects its exit
+status (@pxref{Exit Status}).

+@end menu
+
+Quoting is used to remove the special meaning of certain
+characters or words to the shell.  Quoting can be used to
+disable special treatment for special characters, to prevent
+reserved words from being recognized as such, and to prevent
+parameter expansion.
+
+Each of the shell metacharacters (@pxref{Definitions})
+has special meaning to the shell and must be quoted if it is to
+represent itself.
+When the command history expansion facilities are being used
+(@pxref{History Interaction}), the
+@dfn{history expansion} character, usually @samp{!}, must be quoted
+to prevent history expansion.  @xref{Bash History Facilities}, for
+more details concerning history expansion.
+
+There are three quoting mechanisms: the
+@dfn{escape character}, single quotes, and double quotes.
+
+@node Escape Character
+@subsubsection Escape Character
+A non-quoted backslash @samp{\} is the Bash escape character.
+It preserves the literal value of the next character that follows,
+with the exception of @code{newline}.  If a @code{\newline} pair
+appears, and the backslash itself is not quoted, the @code{\newline}
+is treated as a line continuation (that is, it is removed from
+the input stream and effectively ignored).
+
+@node Single Quotes
+@subsubsection Single Quotes
+
+Enclosing characters in single quotes (@samp{'}) preserves the literal value
+of each character within the quotes.  A single quote may not occur
+between single quotes, even when preceded by a backslash.
+
+@node Double Quotes
+@subsubsection Double Quotes
+
+Enclosing characters in double quotes (@samp{"}) preserves the literal value
+of all characters within the quotes, with the exception of
+@samp{$}, @samp{`}, @samp{\},
+and, when history expansion is enabled, @samp{!}.
+When the shell is in
+@sc{posix} mode (@pxref{Bash POSIX Mode}),
+the @samp{!} has no special meaning
+within double quotes, even when history expansion is enabled.
+The characters @samp{$} and @samp{`}
+retain their special meaning within double quotes (@pxref{Shell Expansions}).
+The backslash retains its special meaning only when followed by one of
+the following characters:
+@samp{$}, @samp{`}, @samp{"}, @samp{\}, or @code{newline}.
+Within double quotes, backslashes that are followed by one of these
+characters are removed.  Backslashes preceding characters without a
+special meaning are left unmodified.
+A double quote may be quoted within double quotes by preceding it with
+a backslash.
+If enabled, history expansion will be performed unless an @samp{!}
+appearing in double quotes is escaped using a backslash.
+The backslash preceding the @samp{!} is not removed.
+
+The special parameters @samp{*} and @samp{@@} have special meaning
+when in double quotes (@pxref{Shell Parameter Expansion}).
+
+@node ANSI-C Quoting
+@subsubsection ANSI-C Quoting
+@cindex quoting, ANSI
+
+Character sequences of the form $'@var{string}' are treated as a special
+kind of single quotes.
+The sequence expands to @var{string}, with backslash-escaped characters
+in @var{string} replaced as specified by the ANSI C standard.
+Backslash escape sequences, if present, are decoded as follows:
+
+@table @code
+@item \a
+alert (bell)
+@item \b
+backspace
+@item \e
+@itemx \E
+an escape character (not ANSI C)
+@item \f
+form feed
+@item \n
+newline
+@item \r
+carriage return
+@item \t
+horizontal tab
+@item \v
+vertical tab
+@item \\
+backslash
+@item \'
+single quote
+@item \"
+double quote
+@item \?
+question mark
+@item \@var{nnn}
+the eight-bit character whose value is the octal value @var{nnn}
+(one to three octal digits)
+@item \x@var{HH}
+the eight-bit character whose value is the hexadecimal value @var{HH}
+(one or two hex digits)
+@item \u@var{HHHH}
+the Unicode (ISO/IEC 10646) character whose value is the hexadecimal value
+@var{HHHH} (one to four hex digits)
+@item \U@var{HHHHHHHH}
+the Unicode (ISO/IEC 10646) character whose value is the hexadecimal value
+@var{HHHHHHHH} (one to eight hex digits)
+@item \c@var{x}
+a control-@var{x} character
+@end table
+
+@noindent
+The expanded result is single-quoted, as if the dollar sign had not
+been present.

+@end menu
+
+Prefixing a double-quoted string with a dollar sign (@samp{$}), such
+as @verb{|$"hello, world"|},
+will cause the string to be translated according to the current locale.
+The @code{gettext} infrastructure performs the lookup and 
+translation, using the @code{LC_MESSAGES}, @code{TEXTDOMAINDIR},
+and @code{TEXTDOMAIN} shell variables, as explained below.
+See the gettext documentation for additional details not covered here.
+If the current locale is @code{C} or @code{POSIX},
+if there are no translations available,
+of if the string is not translated,
+the dollar sign is ignored.
+Since this is a form of double quoting, the string remains double-quoted
+by default, whether or not it is translated and replaced.
+If the @code{noexpand_translation} option is enabled
+using the @code{shopt} builtin (@pxref{The Shopt Builtin}),
+translated strings are single-quoted instead of double-quoted.
+
+The rest of this section is a brief overview of how you use gettext to
+create translations for strings in a shell script named @var{scriptname}.
+There are more details in the gettext documentation.
+
+@node Creating Internationalized Scripts
+@cindex internationalized scripts
+@cindex string translations
+Once you've marked the strings in your script
+that you want to translate using $"...",
+you create a gettext "template" file using the command
+
+@example
+bash --dump-po-strings @var{scriptname} > @var{domain}.pot
+@end example
+
+@noindent
+The @var{domain} is your @dfn{message domain}.
+It's just an arbitrary string that's used to identify the files gettext
+needs, like a package or script name.
+It needs to be unique among all
+the message domains on systems where you install the translations, so
+gettext knows which translations correspond to your script.
+You'll use the template file to create translations for each target language.
+The template file conventionally has the suffix @samp{.pot}.
+
+You copy this template file to a separate file for each target language
+you want to support (called "PO" files, which use the suffix @samp{.po}).
+PO files use various naming conventions, but
+when you are working to translate a template file into a particular
+language, you first copy the template file to a file whose name is the
+language you want to target, with the @samp{.po} suffix.
+For instance, the Spanish translations of your strings would be
+in a file named @samp{es.po}, and to get started using a message
+domain named "example," you would run
+
+@example
+cp example.pot es.po
+@end example
+
+@noindent
+Ultimately, PO files are often named @var{domain}.po and installed in
+directories that contain multiple translation files for a particular language.
+
+Whichever naming convention you choose, you will need to translate the
+strings in the PO files into the appropriate languages.
+This has to be done manually.
+
+When you have the translations and PO files complete, you'll use the
+gettext tools to produce what are called "MO" files, which are compiled
+versions of the PO files the gettext tools use to look up translations
+efficiently.
+MO files are also called "message catalog" files.
+You use the @command{msgfmt} program to do this.
+For instance, if you had a file with Spanish translations, you could run
+
+@example
+msgfmt -o es.mo es.po
+@end example
+
+@noindent
+to produce the corresponding MO file.
+
+Once you have the MO files, you decide where to install them and use the
+@code{TEXTDOMAINDIR} shell variable to tell the gettext tools where they are.
+Make sure to use the same message domain to name the MO files 
+as you did for the PO files when you install them.
+
+@vindex LANG
+@vindex LC_MESSAGES
+@vindex TEXTDOMAIN
+@vindex TEXTDOMAINDIR
+Your users will use the @env{LANG} or @env{LC_MESSAGES} shell variables to
+select the desired language.
+
+You set the @env{TEXTDOMAIN} variable to the script's message domain.
+As above, you use the message domain to name your translation files.
+
+You, or possibly your users, set the @env{TEXTDOMAINDIR} variable to the
+name of a directory where the message catalog files are stored.
+If you install the message files into the system's standard message catalog
+directory, you don't need to worry about this variable.
+
+The directory where the message catalog files are stored varies between
+systems.
+Some use the message catalog selected by the @env{LC_MESSAGES}
+shell variable.
+Others create the name of the message catalog from the value of the
+@env{TEXTDOMAIN} shell variable, possibly adding the @samp{.mo} suffix.
+If you use the @env{TEXTDOMAIN} variable, you may need to set the
+@env{TEXTDOMAINDIR} variable to the location of the message catalog files,
+as above.
+It's common to use both variables in this fashion:
+@env{$TEXTDOMAINDIR}/@env{$LC_MESSAGES}/LC_MESSAGES/@env{$TEXTDOMAIN}.mo.
+
+If you used that last convention, and you wanted to store the message
+catalog files with Spanish (es) and Esperanto (eo) translations into a
+local directory you use for custom translation files, you could run
+
+@example
+TEXTDOMAIN=example
+TEXTDOMAINDIR=/usr/local/share/locale
+
+cp es.mo $@{TEXTDOMAINDIR@}/es/LC_MESSAGES/$@{TEXTDOMAIN@}.mo
+cp eo.mo $@{TEXTDOMAINDIR@}/eo/LC_MESSAGES/$@{TEXTDOMAIN@}.mo
+@end example
+
+When all of this is done, and the message catalog files containing the
+compiled translations are installed in the correct location,
+your users will be able to see translated strings
+in any of the supported languages by setting the @env{LANG} or
+@env{LC_MESSAGES} environment variables before running your script.

+@subsection Reserved Words
+@cindex reserved words
+
+Reserved words are words that have special meaning to the shell.
+They are used to begin and end the shell's compound commands.
+
+The following words are recognized as reserved when unquoted and 
+the first word of a command (see below for exceptions):
+
+@multitable @columnfractions .1 .1 .1 .1 .12 .1
+@item @code{if} @tab @code{then} @tab @code{elif}
+@tab @code{else} @tab @code{fi} @tab @code{time}

+@item @code{@{} @tab @code{@}} @tab @code{[[} @tab @code{]]} @tab @code{!}
+@end multitable
+
+@noindent
+@code{in} is recognized as a reserved word if it is the third word of a
+@code{case} or @code{select} command.
+@code{in} and @code{do} are recognized as reserved
+words if they are the third word in a @code{for} command.
+
+@node Simple Commands
+@subsection Simple Commands
+@cindex commands, simple
+
+A simple command is the kind of command encountered most often.
+It's just a sequence of words separated by @code{blank}s, terminated
+by one of the shell's control operators (@pxref{Definitions}).  The
+first word generally specifies a command to be executed, with the
+rest of the words being that command's arguments.
+
+The return status (@pxref{Exit Status}) of a simple command is
+its exit status as provided
+by the @sc{posix} 1003.1 @code{waitpid} function, or 128+@var{n} if
+the command was terminated by signal @var{n}.
+
+@node Pipelines
+@subsection Pipelines
+@cindex pipeline
+@cindex commands, pipelines
+
+A @code{pipeline} is a sequence of one or more commands separated by
+one of the control operators @samp{|} or @samp{|&}.
+
+@rwindex time
+@rwindex !
+@cindex command timing
+The format for a pipeline is
+@example
+[time [-p]] [!] @var{command1} [ | or |& @var{command2} ] @dots{}
+@end example
+
+@noindent
+The output of each command in the pipeline is connected via a pipe
+to the input of the next command.
+That is, each command reads the previous command's output.  This
+connection is performed before any redirections specified by
+@var{command1}.
+
+If @samp{|&} is used, @var{command1}'s standard error, in addition to
+its standard output, is connected to
+@var{command2}'s standard input through the pipe;
+it is shorthand for @code{2>&1 |}.
+This implicit redirection of the standard error to the standard output is
+performed after any redirections specified by @var{command1}.
+
+The reserved word @code{time} causes timing statistics
+to be printed for the pipeline once it finishes.
+The statistics currently consist of elapsed (wall-clock) time and
+user and system time consumed by the command's execution.
+The @option{-p} option changes the output format to that specified
+by @sc{posix}.
+When the shell is in @sc{posix} mode (@pxref{Bash POSIX Mode}),
+it does not recognize @code{time} as a reserved word if the next
+token begins with a @samp{-}.
+The @env{TIMEFORMAT} variable may be set to a format string that
+specifies how the timing information should be displayed.
+@xref{Bash Variables}, for a description of the available formats.
+The use of @code{time} as a reserved word permits the timing of
+shell builtins, shell functions, and pipelines.  An external
+@code{time} command cannot time these easily.
+
+When the shell is in @sc{posix} mode (@pxref{Bash POSIX Mode}), @code{time}
+may be followed by a newline.  In this case, the shell displays the
+total user and system time consumed by the shell and its children.
+The @env{TIMEFORMAT} variable may be used to specify the format of
+the time information.
+
+If the pipeline is not executed asynchronously (@pxref{Lists}), the
+shell waits for all commands in the pipeline to complete.
+
+Each command in a multi-command pipeline,
+where pipes are created,
+is executed in its own @dfn{subshell}, which is a
+separate process (@pxref{Command Execution Environment}).
+If the @code{lastpipe} option is enabled using the @code{shopt} builtin
+(@pxref{The Shopt Builtin}),
+the last element of a pipeline may be run by the shell process
+when job control is not active.
+
+The exit
+status of a pipeline is the exit status of the last command in the
+pipeline, unless the @code{pipefail} option is enabled
+(@pxref{The Set Builtin}).
+If @code{pipefail} is enabled, the pipeline's return status is the
+value of the last (rightmost) command to exit with a non-zero status,
+or zero if all commands exit successfully.
+If the reserved word @samp{!} precedes the pipeline, the
+exit status is the logical negation of the exit status as described
+above.
+The shell waits for all commands in the pipeline to terminate before
+returning a value.
+
+@node Lists
+@subsection Lists of Commands
+@cindex commands, lists
+
+A @code{list} is a sequence of one or more pipelines separated by one
+of the operators @samp{;}, @samp{&}, @samp{&&}, or @samp{||},
+and optionally terminated by one of @samp{;}, @samp{&}, or a
+@code{newline}.
+
+Of these list operators, @samp{&&} and @samp{||}
+have equal precedence, followed by @samp{;} and @samp{&},
+which have equal precedence.
+
+A sequence of one or more newlines may appear in a @code{list}
+to delimit commands, equivalent to a semicolon.
+
+If a command is terminated by the control operator @samp{&},
+the shell executes the command asynchronously in a subshell.
+This is known as executing the command in the @dfn{background},
+and these are referred to as @dfn{asynchronous} commands.
+The shell does not wait for the command to finish, and the return
+status is 0 (true).
+When job control is not active (@pxref{Job Control}),
+the standard input for asynchronous commands, in the absence of any
+explicit redirections, is redirected from @code{/dev/null}.
+
+Commands separated by a @samp{;} are executed sequentially; the shell
+waits for each command to terminate in turn.  The return status is the
+exit status of the last command executed.
+
+@sc{and} and @sc{or} lists are sequences of one or more pipelines
+separated by the control operators @samp{&&} and @samp{||},
+respectively.  @sc{and} and @sc{or} lists are executed with left
+associativity.
+
+An @sc{and} list has the form
+@example
+@var{command1} && @var{command2}
+@end example
+
+@noindent
+@var{command2} is executed if, and only if, @var{command1}
+returns an exit status of zero (success).
+
+An @sc{or} list has the form
+@example
+@var{command1} || @var{command2}
+@end example
+
+@noindent
+@var{command2} is executed if, and only if, @var{command1}
+returns a non-zero exit status.
+
+The return status of
+@sc{and} and @sc{or} lists is the exit status of the last command
+executed in the list.

+
+@menu
+* Looping Constructs::		Shell commands for iterative action.
+* Conditional Constructs::	Shell commands for conditional execution.
+* Command Grouping::		Ways to group commands.
+@end menu
+
+Compound commands are the shell programming language constructs.
+Each construct begins with a reserved word or control operator and is
+terminated by a corresponding reserved word or operator.
+Any redirections (@pxref{Redirections}) associated with a compound command
+apply to all commands within that compound command unless explicitly overridden.
+
+In most cases a list of commands in a compound command's description may be
+separated from the rest of the command by one or more newlines, and may be
+followed by a newline in place of a semicolon.
+
+Bash provides looping constructs, conditional commands, and mechanisms
+to group commands and execute them as a unit.
+
+@node Looping Constructs
+@subsubsection Looping Constructs
+@cindex commands, looping
+
+Bash supports the following looping constructs.
+
+Note that wherever a @samp{;} appears in the description of a
+command's syntax, it may be replaced with one or more newlines.
+
+@table @code
+@item until
+@rwindex until
+@rwindex do
+@rwindex done
+The syntax of the @code{until} command is:
+
+@example
+until @var{test-commands}; do @var{consequent-commands}; done
+@end example
+
+Execute @var{consequent-commands} as long as
+@var{test-commands} has an exit status which is not zero.
+The return status is the exit status of the last command executed
+in @var{consequent-commands}, or zero if none was executed.
+
+@item while
+@rwindex while
+The syntax of the @code{while} command is:
+
+@example
+while @var{test-commands}; do @var{consequent-commands}; done
+@end example
+
+Execute @var{consequent-commands} as long as
+@var{test-commands} has an exit status of zero.
+The return status is the exit status of the last command executed
+in @var{consequent-commands}, or zero if none was executed.
+
+@item for
+@rwindex for
+The syntax of the @code{for} command is:
+
+@example
+for @var{name} [ [in [@var{words} @dots{}] ] ; ] do @var{commands}; done
+@end example
+
+Expand @var{words} (@pxref{Shell Expansions}), and execute @var{commands}
+once for each member
+in the resultant list, with @var{name} bound to the current member.
+If @samp{in @var{words}} is not present, the @code{for} command
+executes the @var{commands} once for each positional parameter that is
+set, as if @samp{in "$@@"} had been specified
+(@pxref{Special Parameters}).
+
+The return status is the exit status of the last command that executes.
+If there are no items in the expansion of @var{words}, no commands are
+executed, and the return status is zero.
+
+An alternate form of the @code{for} command is also supported:
+
+@example
+for (( @var{expr1} ; @var{expr2} ; @var{expr3} )) ; do @var{commands} ; done
+@end example
+
+First, the arithmetic expression @var{expr1} is evaluated according
+to the rules described below (@pxref{Shell Arithmetic}).
+The arithmetic expression @var{expr2} is then evaluated repeatedly
+until it evaluates to zero.   
+Each time @var{expr2} evaluates to a non-zero value, @var{commands} are
+executed and the arithmetic expression @var{expr3} is evaluated.       
+If any expression is omitted, it behaves as if it evaluates to 1.
+The return value is the exit status of the last command in @var{commands}
+that is executed, or false if any of the expressions is invalid.
+@end table
+
+The @code{break} and @code{continue} builtins (@pxref{Bourne Shell Builtins})
+may be used to control loop execution.
+
+@node Conditional Constructs
+@subsubsection Conditional Constructs
+@cindex commands, conditional
+
+@table @code
+@item if
+@rwindex if
+@rwindex then
+@rwindex else
+@rwindex elif
+@rwindex fi
+The syntax of the @code{if} command is:
+
+@example
+if @var{test-commands}; then
+  @var{consequent-commands};
+[elif @var{more-test-commands}; then
+  @var{more-consequents};]
+[else @var{alternate-consequents};]
+fi
+@end example
+
+The @var{test-commands} list is executed, and if its return status is zero,
+the @var{consequent-commands} list is executed.
+If @var{test-commands} returns a non-zero status, each @code{elif} list
+is executed in turn, and if its exit status is zero,
+the corresponding @var{more-consequents} is executed and the   
+command completes.
+If @samp{else @var{alternate-consequents}} is present, and
+the final command in the final @code{if} or @code{elif} clause
+has a non-zero exit status, then @var{alternate-consequents} is executed.
+The return status is the exit status of the last command executed, or
+zero if no condition tested true.
+
+@item case
+@rwindex case
+@rwindex in
+@rwindex esac
+The syntax of the @code{case} command is:
+
+@example
+case @var{word} in
+    [ [(] @var{pattern} [| @var{pattern}]@dots{}) @var{command-list} ;;]@dots{}
+esac
+@end example
+
+@code{case} will selectively execute the @var{command-list} corresponding to
+the first @var{pattern} that matches @var{word}.
+The match is performed according
+to the rules described below in @ref{Pattern Matching}.
+If the @code{nocasematch} shell option
+(see the description of @code{shopt} in @ref{The Shopt Builtin})
+is enabled, the match is performed without regard to the case
+of alphabetic characters.
+The @samp{|} is used to separate multiple patterns, and the @samp{)}
+operator terminates a pattern list.
+A list of patterns and an associated command-list is known
+as a @var{clause}.
+
+Each clause must be terminated with @samp{;;}, @samp{;&}, or @samp{;;&}.
+The @var{word} undergoes tilde expansion, parameter expansion, command
+substitution, arithmetic expansion, and quote removal
+(@pxref{Shell Parameter Expansion})
+before matching is attempted.
+Each @var{pattern} undergoes tilde expansion, parameter expansion,
+command substitution, arithmetic expansion, process substitution, and
+quote removal.
+
+There may be an arbitrary number of @code{case} clauses, each terminated
+by a @samp{;;}, @samp{;&}, or @samp{;;&}.
+The first pattern that matches determines the
+command-list that is executed.
+It's a common idiom to use @samp{*} as the final pattern to define the
+default case, since that pattern will always match.
+
+Here is an example using @code{case} in a script that could be used to
+describe one interesting feature of an animal:
+
+@example
+echo -n "Enter the name of an animal: "
+read ANIMAL
+echo -n "The $ANIMAL has "
+case $ANIMAL in
+  horse | dog | cat) echo -n "four";;
+  man | kangaroo ) echo -n "two";;
+  *) echo -n "an unknown number of";;
+esac
+echo " legs."
+@end example
+
+@noindent
+
+If the @samp{;;} operator is used, no subsequent matches are attempted after
+the first pattern match.
+Using @samp{;&}  in place of @samp{;;} causes execution to continue with
+the @var{command-list} associated with the next clause, if any.
+Using @samp{;;&} in place of @samp{;;} causes the shell to test the patterns
+in the next clause, if any, and execute any associated @var{command-list}
+on a successful match,
+continuing the case statement execution as if the pattern list had not matched.
+
+The return status is zero if no @var{pattern} is matched.  Otherwise, the
+return status is the exit status of the @var{command-list} executed.
+
+@item select
+@rwindex select
+
+The @code{select} construct allows the easy generation of menus.
+It has almost the same syntax as the @code{for} command:
+
+@example
+select @var{name} [in @var{words} @dots{}]; do @var{commands}; done
+@end example
+
+The list of words following @code{in} is expanded, generating a list
+of items, and the set of expanded words is printed on the standard
+error output stream, each preceded by a number.  If the
+@samp{in @var{words}} is omitted, the positional parameters are printed,
+as if @samp{in "$@@"} had been specified.
+@code{select} then displays the @env{PS3}
+prompt and reads a line from the standard input.
+If the line consists of a number corresponding to one of the displayed
+words, then the value of @var{name} is set to that word.
+If the line is empty, the words and prompt are displayed again.
+If @code{EOF} is read, the @code{select} command completes and returns 1.
+Any other value read causes @var{name} to be set to null.
+The line read is saved in the variable @env{REPLY}.
+
+The @var{commands} are executed after each selection until a
+@code{break} command is executed, at which
+point the @code{select} command completes.
+
+Here is an example that allows the user to pick a filename from the
+current directory, and displays the name and index of the file
+selected.
+
+@example
+select fname in *;
+do
+	echo you picked $fname \($REPLY\)
+	break;
+done
+@end example
+
+@item ((@dots{}))
+@example
+(( @var{expression} ))
+@end example
+
+The arithmetic @var{expression} is evaluated according to the rules
+described below (@pxref{Shell Arithmetic}).
+The @var{expression} undergoes the same expansions
+as if it were within double quotes,
+but double quote characters in @var{expression} are not treated specially
+are removed.
+If the value of the expression is non-zero, the return status is 0;
+otherwise the return status is 1. 
+
+
+@item [[@dots{}]]
+@rwindex [[
+@rwindex ]]
+@example
+[[ @var{expression} ]]
+@end example
+
+Return a status of 0 or 1 depending on the evaluation of
+the conditional expression @var{expression}.
+Expressions are composed of the primaries described below in
+@ref{Bash Conditional Expressions}.
+The words between the @code{[[} and @code{]]} do not undergo word splitting
+and filename expansion.
+The shell performs tilde expansion, parameter and
+variable expansion, arithmetic expansion, command substitution, process
+substitution, and quote removal on those words
+(the expansions that would occur if the words were enclosed in double quotes).
+Conditional operators such as @samp{-f} must be unquoted to be recognized
+as primaries.
+
+When used with @code{[[}, the @samp{<} and @samp{>} operators sort
+lexicographically using the current locale.
+
+When the @samp{==} and @samp{!=} operators are used, the string to the
+right of the operator is considered a pattern and matched according
+to the rules described below in @ref{Pattern Matching},
+as if the @code{extglob} shell option were enabled.
+The @samp{=} operator is identical to @samp{==}.
+If the @code{nocasematch} shell option
+(see the description of @code{shopt} in @ref{The Shopt Builtin})
+is enabled, the match is performed without regard to the case
+of alphabetic characters.
+The return value is 0 if the string matches (@samp{==}) or does not
+match (@samp{!=}) the pattern, and 1 otherwise.
+
+If you quote any part of the pattern,
+using any of the shell's quoting mechanisms,
+the quoted portion is matched literally.
+This means every character in the quoted portion matches itself,
+instead of having any special pattern matching meaning.
+
+An additional binary operator, @samp{=~}, is available, with the same
+precedence as @samp{==} and @samp{!=}.
+When you use @samp{=~}, the string to the right of the operator is considered
+a @sc{posix} extended regular expression pattern and matched accordingly
+(using the @sc{posix} @code{regcomp} and @code{regexec} interfaces
+usually described in @i{regex}(3)).
+The return value is 0 if the string matches the pattern, and 1 if it does not.
+If the regular expression is syntactically incorrect, the conditional
+expression returns 2.
+If the @code{nocasematch} shell option
+(see the description of @code{shopt} in @ref{The Shopt Builtin})
+is enabled, the match is performed without regard to the case
+of alphabetic characters.
+
+You can quote any part of the pattern
+to force the quoted portion to be matched literally
+instead of as a regular expression (see above).
+If the pattern is stored in a shell variable, quoting the variable
+expansion forces the entire pattern to be matched literally.
+
+The pattern will match if it matches any part of the string.
+If you want to force the pattern to match the entire string,
+anchor the pattern using the @samp{^} and @samp{$} regular expression
+operators.
+
+For example, the following will match a line
+(stored in the shell variable @code{line})
+if there is a sequence of characters anywhere in the value consisting of
+any number, including zero, of 
+characters in the @code{space} character class,
+immediately followed by zero or one instances of @samp{a},
+then a @samp{b}:
+
+@example
+[[ $line =~ [[:space:]]*(a)?b ]]
+@end example
+
+@noindent
+That means values for @code{line} like
+@samp{aab}, @samp{  aaaaaab}, @samp{xaby}, and @samp{ ab}
+will all match,
+as will a line containing a @samp{b} anywhere in its value.
+
+If you want to match a character that's special to the regular expression
+grammar (@samp{^$|[]()\.*+?}), it has to be quoted to remove its special
+meaning.
+This means that in the pattern @samp{xxx.txt}, the @samp{.} matches any
+character in the string (its usual regular expression meaning), but in the
+pattern @samp{"xxx.txt"}, it can only match a literal @samp{.}.
+
+Likewise, if you want to include a character in your pattern that has a
+special meaning to the regular expression grammar, you must make sure it's
+not quoted.
+If you want to anchor a pattern at the beginning or end of the string,
+for instance, you cannot quote the @samp{^} or @samp{$}
+characters using any form of shell quoting.
+
+If you want to match @samp{initial string} at the start of a line,
+the following will work:
+@example
+[[ $line =~ ^"initial string" ]]
+@end example
+@noindent
+but this will not:
+@example
+[[ $line =~ "^initial string" ]]
+@end example
+@noindent
+because in the second example the @samp{^} is quoted and doesn't have its
+usual special meaning.
+
+It is sometimes difficult to specify a regular expression properly
+without using quotes, or to keep track of the quoting used by regular
+expressions while paying attention to
+shell quoting and the shell's quote removal.
+Storing the regular expression in a shell variable is often a useful
+way to avoid problems with quoting characters that are special to the
+shell.
+For example, the following is equivalent to the pattern used above:
+
+@example
+pattern='[[:space:]]*(a)?b'
+[[ $line =~ $pattern ]]
+@end example
+
+Shell programmers should take special care with backslashes, since
+backslashes are used by both the shell and regular expressions to remove
+the special meaning from the following character.
+This means that after the shell's word expansions complete
+(@pxref{Shell Expansions}),
+any backslashes remaining in parts of the pattern
+that were originally not quoted can remove the
+special meaning of pattern characters.
+If any part of the pattern is quoted, the shell does its best to ensure that
+the regular expression treats those remaining backslashes as literal,
+if they appeared in a quoted portion.
+
+The following two sets of commands are @emph{not} equivalent:
+
+@example
+pattern='\.'
+
+[[ . =~ $pattern ]]
+[[ . =~ \. ]]
+
+[[ . =~ "$pattern" ]]
+[[ . =~ '\.' ]]
+@end example
+
+@noindent
+The first two matches will succeed, but the second two will not, because
+in the second two the backslash will be part of the pattern to be matched.
+In the first two examples, the pattern passed to the regular expression
+parser is @samp{\.}. The backslash removes the special meaning from
+@samp{.}, so the literal @samp{.} matches.
+In the second two examples, the pattern passed to the regular expression
+parser has the backslash quoted (e.g., @samp{\\\.}), which will not match
+the string, since it does not contain a backslash.
+If the string in the first examples were anything other than @samp{.}, say
+@samp{a}, the pattern would not match, because the quoted @samp{.} in the
+pattern loses its special meaning of matching any single character.
+
+Bracket expressions in regular expressions can be sources of errors as well,
+since characters that are normally special in regular expressions
+lose their special meanings between brackets.
+However, you can use bracket expressions to match special pattern characters
+without quoting them, so they are sometimes useful for this purpose.
+
+Though it might seem like a strange way to write it, the following pattern
+will match a @samp{.} in the string:
+
+@example
+[[ . =~ [.] ]]
+@end example
+
+The shell performs any word expansions before passing the pattern
+to the regular expression functions,
+so you can assume that the shell's quoting takes precedence.
+As noted above, the regular expression parser will interpret any
+unquoted backslashes remaining in the pattern after shell expansion
+according to its own rules.
+The intention is to avoid making shell programmers quote things twice
+as much as possible, so shell quoting should be sufficient to quote
+special pattern characters where that's necessary.
+
+The array variable @code{BASH_REMATCH} records which parts of the string
+matched the pattern.
+The element of @code{BASH_REMATCH} with index 0 contains the portion of
+the string matching the entire regular expression.
+Substrings matched by parenthesized subexpressions within the regular
+expression are saved in the remaining @code{BASH_REMATCH} indices.
+The element of @code{BASH_REMATCH} with index @var{n} is the portion of the
+string matching the @var{n}th parenthesized subexpression.
+
+Bash sets
+@code{BASH_REMATCH}
+in the global scope; declaring it as a local variable will lead to
+unexpected results.
+
+Expressions may be combined using the following operators, listed
+in decreasing order of precedence:
+
+@table @code
+@item ( @var{expression} )
+Returns the value of @var{expression}.
+This may be used to override the normal precedence of operators.
+
+@item ! @var{expression}
+True if @var{expression} is false.
+
+@item @var{expression1} && @var{expression2}
+True if both @var{expression1} and @var{expression2} are true.
+
+@item @var{expression1} || @var{expression2}
+True if either @var{expression1} or @var{expression2} is true.
+@end table
+
+@noindent
+The @code{&&} and @code{||} operators do not evaluate @var{expression2} if the
+value of @var{expression1} is sufficient to determine the return
+value of the entire conditional expression.
+@end table
+
+@node Command Grouping
+@subsubsection Grouping Commands
+@cindex commands, grouping
+
+Bash provides two ways to group a list of commands to be executed
+as a unit.  When commands are grouped, redirections may be applied
+to the entire command list.  For example, the output of all the
+commands in the list may be redirected to a single stream.
+
+@table @code
+@item ()
+@example
+( @var{list} )
+@end example
+
+Placing a list of commands between parentheses forces the shell to create
+a subshell (@pxref{Command Execution Environment}), and each
+of the commands in @var{list} is executed in that subshell environment.
+Since the @var{list} is executed in a subshell, variable assignments do not
+remain in effect after the subshell completes. 
+
+@item @{@}
+@rwindex @{
+@rwindex @}
+@example
+@{ @var{list}; @}
+@end example
+
+Placing a list of commands between curly braces causes the list to
+be executed in the current shell context.  No subshell is created.
+The semicolon (or newline) following @var{list} is required.
+@end table
+
+In addition to the creation of a subshell, there is a subtle difference
+between these two constructs due to historical reasons.  The braces
+are reserved words, so they must be separated from the @var{list}
+by @code{blank}s or other shell metacharacters.
+The parentheses are operators, and are
+recognized as separate tokens by the shell even if they are not separated
+from the @var{list} by whitespace.
+
+The exit status of both of these constructs is the exit status of
+@var{list}.
+
+@node Coprocesses
+@subsection Coprocesses
+@cindex coprocess
+
+A @code{coprocess} is a shell command preceded by the @code{coproc}
+reserved word.
+A coprocess is executed asynchronously in a subshell, as if the command
+had been terminated with the @samp{&} control operator, with a two-way pipe
+established between the executing shell and the coprocess.
+
+The syntax for a coprocess is:
+
+@example
+coproc [@var{NAME}] @var{command} [@var{redirections}]
+@end example
+
+@noindent
+This creates a coprocess named @var{NAME}.
+@var{command} may be either a simple command (@pxref{Simple Commands})
+or a compound command (@pxref{Compound Commands}).
+@var{NAME} is a shell variable name.
+If @var{NAME} is not supplied, the default name is @code{COPROC}.
+
+The recommended form to use for a coprocess is
+
+@example
+coproc @var{NAME} @{ @var{command}; @}
+@end example
+
+@noindent
+This form is recommended because simple commands result in the coprocess
+always being named @code{COPROC}, and it is simpler to use and more complete
+than the other compound commands.
+
+There are other forms of coprocesses:
+
+@example
+coproc @var{NAME} @var{compound-command}
+coproc @var{compound-command}
+coproc @var{simple-command}
+@end example
+
+@noindent
+If @var{command} is a compound command, @var{NAME} is optional. The
+word following @code{coproc} determines whether that word is interpreted
+as a variable name: it is interpreted as @var{NAME} if it is not a
+reserved word that introduces a compound command.
+If @var{command} is a simple command, @var{NAME} is not allowed; this
+is to avoid confusion between @var{NAME} and the first word of the simple
+command.
+
+When the coprocess is executed, the shell creates an array variable
+(@pxref{Arrays})
+named @var{NAME} in the context of the executing shell.
+The standard output of @var{command}
+is connected via a pipe to a file descriptor in the executing shell,
+and that file descriptor is assigned to @var{NAME}[0].
+The standard input of @var{command}
+is connected via a pipe to a file descriptor in the executing shell,
+and that file descriptor is assigned to @var{NAME}[1].
+This pipe is established before any redirections specified by the
+command (@pxref{Redirections}).
+The file descriptors can be utilized as arguments to shell commands
+and redirections using standard word expansions.
+Other than those created to execute command and process substitutions,
+the file descriptors are not available in subshells.
+
+The process ID of the shell spawned to execute the coprocess is
+available as the value of the variable @env{@var{NAME}_PID}.
+The @code{wait}
+builtin command may be used to wait for the coprocess to terminate.
+
+Since the coprocess is created as an asynchronous command,
+the @code{coproc} command always returns success.
+The return status of a coprocess is the exit status of @var{command}.

+@node GNU Parallel
+@subsection GNU Parallel
+
+There are ways to run commands in parallel that are not built into Bash.
+GNU Parallel is a tool to do just that.
+
+GNU Parallel, as its name suggests, can be used to build and run commands
+in parallel.  You may run the same command with different arguments, whether
+they are filenames, usernames, hostnames, or lines read from files.  GNU
+Parallel provides shorthand references to many of the most common operations
+(input lines, various portions of the input line, different ways to specify
+the input source, and so on).  Parallel can replace @code{xargs} or feed
+commands from its input sources to several different instances of Bash.
+
+For a complete description, refer to the GNU Parallel documentation, which
+is available at
+@url{https://www.gnu.org/software/parallel/parallel_tutorial.html}.
+
+@node Shell Functions
+@section Shell Functions
+@cindex shell function
+@cindex functions, shell
+
+Shell functions are a way to group commands for later execution
+using a single name for the group.  They are executed just like
+a "regular" command.
+When the name of a shell function is used as a simple command name,
+the list of commands associated with that function name is executed.
+Shell functions are executed in the current
+shell context; no new process is created to interpret them.
+
+Functions are declared using this syntax:
+@rwindex function
+@example
+@var{fname} () @var{compound-command} [ @var{redirections} ]
+@end example
+
+or
+
+@example
+function @var{fname} [()] @var{compound-command} [ @var{redirections} ]
+@end example
+
+This defines a shell function named @var{fname}.  The reserved
+word @code{function} is optional.
+If the @code{function} reserved
+word is supplied, the parentheses are optional.
+The @dfn{body} of the function is the compound command
+@var{compound-command} (@pxref{Compound Commands}).
+That command is usually a @var{list} enclosed between @{ and @}, but
+may be any compound command listed above.
+If the @code{function} reserved word is used, but the
+parentheses are not supplied, the braces are recommended.
+@var{compound-command} is executed whenever @var{fname} is specified as the
+name of a simple command.
+When the shell is in @sc{posix} mode (@pxref{Bash POSIX Mode}),
+@var{fname} must be a valid shell name and
+may not be the same as one of the special builtins
+(@pxref{Special Builtins}).
+In default mode, a function name can be any unquoted shell word that does
+not contain @samp{$}.
+Any redirections (@pxref{Redirections}) associated with the shell function
+are performed when the function is executed.
+A function definition may be deleted using the @option{-f} option to the
+@code{unset} builtin (@pxref{Bourne Shell Builtins}).
+
+The exit status of a function definition is zero unless a syntax error
+occurs or a readonly function with the same name already exists.
+When executed, the exit status of a function is the exit status of the
+last command executed in the body.
+
+Note that for historical reasons, in the most common usage the curly braces
+that surround the body of the function must be separated from the body by
+@code{blank}s or newlines.
+This is because the braces are reserved words and are only recognized
+as such when they are separated from the command list
+by whitespace or another shell metacharacter.
+Also, when using the braces, the @var{list} must be terminated by a semicolon,
+a @samp{&}, or a newline.
+
+When a function is executed, the arguments to the
+function become the positional parameters
+during its execution (@pxref{Positional Parameters}).
+The special parameter @samp{#} that expands to the number of
+positional parameters is updated to reflect the change.
+Special parameter @code{0} is unchanged.
+The first element of the @env{FUNCNAME} variable is set to the
+name of the function while the function is executing.
+
+All other aspects of the shell execution
+environment are identical between a function and its caller
+with these exceptions:
+the @env{DEBUG} and @env{RETURN} traps
+are not inherited unless the function has been given the
+@code{trace} attribute using the @code{declare} builtin or
+the @code{-o functrace} option has been enabled with
+the @code{set} builtin,
+(in which case all functions inherit the @env{DEBUG} and @env{RETURN} traps),
+and the @env{ERR} trap is not inherited unless the @code{-o errtrace}
+shell option has been enabled.
+@xref{Bourne Shell Builtins}, for the description of the
+@code{trap} builtin.
+
+The @env{FUNCNEST} variable, if set to a numeric value greater
+than 0, defines a maximum function nesting level.  Function
+invocations that exceed the limit cause the entire command to
+abort.
+
+If the builtin command @code{return}
+is executed in a function, the function completes and
+execution resumes with the next command after the function
+call.
+Any command associated with the @code{RETURN} trap is executed
+before execution resumes.
+When a function completes, the values of the
+positional parameters and the special parameter @samp{#}
+are restored to the values they had prior to the function's
+execution.  If a numeric argument is given to @code{return},
+that is the function's return status; otherwise the function's
+return status is the exit status of the last command executed
+before the @code{return}.
+
+Variables local to the function may be declared with the
+@code{local} builtin (@dfn{local variables}).
+Ordinarily, variables and their values
+are shared between a function and its caller.
+These variables are visible only to
+the function and the commands it invokes.  This is particularly
+important when a shell function calls other functions.
+
+In the following description, the @dfn{current scope} is a currently-
+executing function.
+Previous scopes consist of that function's caller and so on,
+back to the "global" scope, where the shell is not executing
+any shell function.
+Consequently, a local variable at the current local scope is a variable
+declared using the @code{local} or @code{declare} builtins in the
+function that is currently executing.
+
+Local variables "shadow" variables with the same name declared at
+previous scopes.  For instance, a local variable declared in a function
+hides a global variable of the same name: references and assignments
+refer to the local variable, leaving the global variable unmodified.
+When the function returns, the global variable is once again visible.
+
+The shell uses @dfn{dynamic scoping} to control a variable's visibility
+within functions.
+With dynamic scoping, visible variables and their values
+are a result of the sequence of function calls that caused execution
+to reach the current function.
+The value of a variable that a function sees depends
+on its value within its caller, if any, whether that caller is
+the "global" scope or another shell function.
+This is also the value that a local variable
+declaration "shadows", and the value that is restored when the function
+returns.
+
+For example, if a variable @env{var} is declared as local in function
+@code{func1}, and @code{func1} calls another function @code{func2},
+references to @env{var} made from within @code{func2} will resolve to the
+local variable @env{var} from @code{func1}, shadowing any global variable
+named @env{var}.
+
+The following script demonstrates this behavior.
+When executed, the script displays
+
+@example
+In func2, var = func1 local
+@end example
+
+@example
+func1()
+@{
+    local var='func1 local'
+    func2
+@}
+
+func2()
+@{
+    echo "In func2, var = $var"
+@}
+
+var=global
+func1
+@end example
+
+The @code{unset} builtin also acts using the same dynamic scope: if a  
+variable is local to the current scope, @code{unset} will unset it;         
+otherwise the unset will refer to the variable found in any calling scope 
+as described above.
+If a variable at the current local scope is unset, it will remain so
+(appearing as unset)
+until it is reset in that scope or until the function returns.
+Once the function returns, any instance of the variable at a previous
+scope will become visible.
+If the unset acts on a variable at a previous scope, any instance of a   
+variable with that name that had been shadowed will become visible
+(see below how @code{localvar_unset}shell option changes this behavior).
+
+Function names and definitions may be listed with the
+@option{-f} option to the @code{declare} (@code{typeset})
+builtin command (@pxref{Bash Builtins}).
+The @option{-F} option to @code{declare} or @code{typeset}
+will list the function names only
+(and optionally the source file and line number, if the @code{extdebug}
+shell option is enabled).
+Functions may be exported so that child shell processes
+(those created when executing a separate shell invocation)
+automatically have them defined with the
+@option{-f} option to the @code{export} builtin
+(@pxref{Bourne Shell Builtins}).
+
+Functions may be recursive.
+The @code{FUNCNEST} variable may be used to limit the depth of the
+function call stack and restrict the number of function invocations.
+By default, no limit is placed on the number of recursive  calls.

+* Special Parameters::		Parameters denoted by special characters.
+@end menu
+
+A @dfn{parameter} is an entity that stores values.
+It can be a @code{name}, a number, or one of the special characters
+listed below.
+A @dfn{variable} is a parameter denoted by a @code{name}.
+A variable has a @code{value} and zero or more @code{attributes}.
+Attributes are assigned using the @code{declare} builtin command
+(see the description of the @code{declare} builtin in @ref{Bash Builtins}).
+
+A parameter is set if it has been assigned a value.  The null string is
+a valid value.  Once a variable is set, it may be unset only by using
+the @code{unset} builtin command.
+
+A variable may be assigned to by a statement of the form
+@example
+@var{name}=[@var{value}]
+@end example
+@noindent
+If @var{value}
+is not given, the variable is assigned the null string.  All
+@var{value}s undergo tilde expansion, parameter and variable expansion,
+command substitution, arithmetic expansion, and quote
+removal (@pxref{Shell Parameter Expansion}).
+If the variable has its @code{integer}
+attribute set, then @var{value} 
+is evaluated as an arithmetic expression even if the @code{$((@dots{}))}
+expansion is not used (@pxref{Arithmetic Expansion}).
+Word splitting and filename expansion are not performed.
+Assignment statements may also appear as arguments to the
+@code{alias}, 
+@code{declare}, @code{typeset}, @code{export}, @code{readonly},
+and @code{local} builtin commands (@dfn{declaration} commands).
+When in @sc{posix} mode (@pxref{Bash POSIX Mode}), these builtins may appear
+in a command after one or more instances of the @code{command} builtin
+and retain these assignment statement properties.
+
+In the context where an assignment statement is assigning a value  
+to a shell variable or array index (@pxref{Arrays}), the @samp{+=}
+operator can be used to   
+append to or add to the variable's previous value.
+This includes arguments to builtin commands such as @code{declare} that
+accept assignment statements (declaration commands).
+When @samp{+=} is applied to a variable for which the @code{integer} attribute
+has been set, @var{value} is evaluated as an arithmetic expression and
+added to the variable's current value, which is also evaluated.
+When @samp{+=} is applied to an array variable using compound assignment
+(@pxref{Arrays}), the
+variable's value is not unset (as it is when using @samp{=}), and new
+values are appended to the array beginning at one greater than the array's
+maximum index (for indexed arrays),  or added as additional key-value pairs
+in an associative array.
+When applied to a string-valued variable, @var{value} is expanded and
+appended to the variable's value.
+
+A variable can be assigned the @code{nameref} attribute using the
+@option{-n} option to the @code{declare} or @code{local} builtin commands
+(@pxref{Bash Builtins})
+to create a @dfn{nameref}, or a reference to another variable.
+This allows variables to be manipulated indirectly.
+Whenever the nameref variable is referenced, assigned to, unset, or has
+its attributes modified (other than using or changing the nameref
+attribute itself), the
+operation is actually performed on the variable specified by the nameref
+variable's value.
+A nameref is commonly used within shell functions to refer to a variable
+whose name is passed as an argument to the function.
+For instance, if a variable name is passed to a shell function as its first
+argument, running
+@example
+declare -n ref=$1
+@end example
+@noindent
+inside the function creates a nameref variable @env{ref} whose value is
+the variable name passed as the first argument.
+References and assignments to @env{ref}, and changes to its attributes,
+are treated as references, assignments, and attribute modifications
+to the variable whose name was passed as @code{$1}.
+
+If the control variable in a @code{for} loop has the nameref attribute,
+the list of words can be a list of shell variables, and a name reference
+will be established for each word in the list, in turn, when the loop is
+executed.
+Array variables cannot be given the nameref attribute.
+However, nameref variables can reference array variables and subscripted
+array variables.
+Namerefs can be unset using the @option{-n} option to the @code{unset} builtin
+(@pxref{Bourne Shell Builtins}).
+Otherwise, if @code{unset} is executed with the name of a nameref variable
+as an argument, the variable referenced by the nameref variable will be unset.
+
+@node Positional Parameters
+@subsection Positional Parameters
+@cindex parameters, positional
+
+A @dfn{positional parameter} is a parameter denoted by one or more
+digits, other than the single digit @code{0}.  Positional parameters are
+assigned from the shell's arguments when it is invoked,
+and may be reassigned using the @code{set} builtin command.
+Positional parameter @code{N} may be referenced as @code{$@{N@}}, or
+as @code{$N} when @code{N} consists of a single digit.
+Positional parameters may not be assigned to with assignment statements.
+The @code{set} and @code{shift} builtins are used to set and
+unset them (@pxref{Shell Builtin Commands}).
+The positional parameters are
+temporarily replaced when a shell function is executed
+(@pxref{Shell Functions}).
+
+When a positional parameter consisting of more than a single
+digit is expanded, it must be enclosed in braces.
+
+@node Special Parameters
+@subsection Special Parameters
+@cindex parameters, special
+
+The shell treats several parameters specially.  These parameters may
+only be referenced; assignment to them is not allowed.
+
+@vtable @code
+
+@item *
+@vindex $*
+($*) Expands to the positional parameters, starting from one.
+When the expansion is not within double quotes, each positional parameter
+expands to a separate word.
+In contexts where it is performed, those words
+are subject to further word splitting and filename expansion.
+When the expansion occurs within double quotes, it expands to a single word
+with the value of each parameter separated by the first character of the
+@env{IFS} special variable.  That is, @code{"$*"} is equivalent
+to @code{"$1@var{c}$2@var{c}@dots{}"}, where @var{c}
+is the first character of the value of the @code{IFS}
+variable.
+If @env{IFS} is unset, the parameters are separated by spaces.
+If @env{IFS} is null, the parameters are joined without intervening
+separators.
+
+@item @@
+@vindex $@@
+($@@) Expands to the positional parameters, starting from one.
+In contexts where word splitting is performed, this expands each
+positional parameter to a separate word; if not within double
+quotes, these words are subject to word splitting.
+In contexts where word splitting is not performed,
+this expands to a single word
+with each positional parameter separated by a space.
+When the
+expansion occurs within double quotes, and word splitting is performed,
+each parameter expands to a
+separate word.  That is, @code{"$@@"} is equivalent to
+@code{"$1" "$2" @dots{}}.
+If the double-quoted expansion occurs within a word, the expansion of
+the first parameter is joined with the beginning part of the original
+word, and the expansion of the last parameter is joined with the last
+part of the original word.
+When there are no positional parameters, @code{"$@@"} and
+@code{$@@}
+expand to nothing (i.e., they are removed).
+
+@item #
+@vindex $#
+($#) Expands to the number of positional parameters in decimal.
+
+@item ?
+@vindex $?
+($?) Expands to the exit status of the most recently executed foreground
+pipeline.
+
+@item -
+@vindex $-
+($-, a hyphen.)  Expands to the current option flags as specified upon
+invocation, by the @code{set}
+builtin command, or those set by the shell itself
+(such as the @option{-i} option).
+
+@item $
+@vindex $$
+($$) Expands to the process @sc{id} of the shell.  In a subshell, it
+expands to the process @sc{id} of the invoking shell, not the subshell.
+
+@item !
+@vindex $!
+($!) Expands to the process @sc{id} of the job most recently placed into the
+background, whether executed as an asynchronous command or using
+the @code{bg} builtin (@pxref{Job Control Builtins}).
+
+@item 0
+@vindex $0
+($0) Expands to the name of the shell or shell script.  This is set at
+shell initialization.  If Bash is invoked with a file of commands
+(@pxref{Shell Scripts}), @code{$0} is set to the name of that file.
+If Bash is started with the @option{-c} option (@pxref{Invoking Bash}),
+then @code{$0} is set to the first argument after the string to be
+executed, if one is present.  Otherwise, it is set
+to the filename used to invoke Bash, as given by argument zero.
+@end vtable

+@node Shell Expansions
+@section Shell Expansions
+@cindex expansion

+Expansion is performed on the command line after it has been split into
+@code{token}s.  There are seven kinds of expansion performed:
+
+@itemize @bullet

+@item parameter and variable expansion
+@item command substitution
+@item arithmetic expansion
+@item word splitting

+
+The order of expansions is:
+brace expansion;
+tilde expansion, parameter and variable expansion, arithmetic expansion,
+and command substitution (done in a left-to-right fashion);
+word splitting;
+and filename expansion.
+
+On systems that can support it, there is an additional expansion
+available: @dfn{process substitution}.
+This is performed at the
+same time as tilde, parameter, variable, and arithmetic expansion and
+command substitution.
+
+After these expansions are performed, quote characters present in the
+original word are removed unless they have been quoted themselves
+(@dfn{quote removal}).
+
+Only brace expansion, word splitting, and filename expansion
+can increase the number of words of the expansion; other expansions
+expand a single word to a single word.
+The only exceptions to this are the expansions of
+@code{"$@@"} and @code{$*} (@pxref{Special Parameters}), and
+@code{"$@{@var{name}[@@]@}"} and @code{$@{@var{name}[*]@}}
+(@pxref{Arrays}).
+
+After all expansions, @code{quote removal} (@pxref{Quote Removal})
+is performed.
+
+@node Brace Expansion
+@subsection Brace Expansion
+@cindex brace expansion
+@cindex expansion, brace
+
+Brace expansion is a mechanism by which arbitrary strings may be generated.
+This mechanism is similar to
+@dfn{filename expansion} (@pxref{Filename Expansion}),
+but the filenames generated need not exist.
+Patterns to be brace expanded take the form of an optional @var{preamble},
+followed by either a series of comma-separated strings or a sequence expression
+between a pair of braces,
+followed by an optional @var{postscript}.
+The preamble is prefixed to each string contained within the braces, and
+the postscript is then appended to each resulting string, expanding left
+to right.
+
+Brace expansions may be nested.
+The results of each expanded string are not sorted; left to right order
+is preserved.
+For example,
+@example
+bash$ echo a@{d,c,b@}e
+ade ace abe
+@end example
+
+A sequence expression takes the form @code{@{@var{x}..@var{y}[..@var{incr}]@}},
+where @var{x} and @var{y} are either integers or letters,
+and @var{incr}, an optional increment, is an integer.
+When integers are supplied, the expression expands to each number between
+@var{x} and @var{y}, inclusive.
+Supplied integers may be prefixed with @samp{0} to force each term to have the
+same width.
+When either @var{x} or @var{y} begins with a zero, the shell
+attempts to force all generated terms to contain the same number of digits,
+zero-padding where necessary.
+When letters are supplied, the expression expands to each character
+lexicographically between @var{x} and @var{y}, inclusive,
+using the default C locale.
+Note that both @var{x} and @var{y} must be of the same type
+(integer or letter).
+When the increment is supplied, it is used as the difference between
+each term.  The default increment is 1 or -1 as appropriate.
+
+Brace expansion is performed before any other expansions,
+and any characters special to other expansions are preserved
+in the result.  It is strictly textual.  Bash
+does not apply any syntactic interpretation to the context of the
+expansion or the text between the braces.
+
+A correctly-formed brace expansion must contain unquoted opening
+and closing braces, and at least one unquoted comma or a valid
+sequence expression.
+Any incorrectly formed brace expansion is left unchanged.
+
+A @{ or @samp{,} may be quoted with a backslash to prevent its
+being considered part of a brace expression.
+To avoid conflicts with parameter expansion, the string @samp{$@{}
+is not considered eligible for brace expansion,
+and inhibits brace expansion until the closing @samp{@}}.
+
+This construct is typically used as shorthand when the common
+prefix of the strings to be generated is longer than in the
+above example:
+@example
+mkdir /usr/local/src/bash/@{old,new,dist,bugs@}
+@end example
+or
+@example
+chown root /usr/@{ucb/@{ex,edit@},lib/@{ex?.?*,how_ex@}@}
+@end example
+
+@node Tilde Expansion
+@subsection Tilde Expansion
+@cindex tilde expansion
+@cindex expansion, tilde
+
+If a word begins with an unquoted tilde character (@samp{~}), all of the
+characters up to the first unquoted slash (or all characters,
+if there is no unquoted slash) are considered a @dfn{tilde-prefix}.
+If none of the characters in the tilde-prefix are quoted, the
+characters in the tilde-prefix following the tilde are treated as a
+possible @dfn{login name}.
+If this login name is the null string, the tilde is replaced with the
+value of the @env{HOME} shell variable.
+If @env{HOME} is unset, the home directory of the user executing the
+shell is substituted instead.
+Otherwise, the tilde-prefix is replaced with the home directory
+associated with the specified login name.
+
+If the tilde-prefix is @samp{~+}, the value of
+the shell variable @env{PWD} replaces the tilde-prefix.
+If the tilde-prefix is @samp{~-}, the value of the shell variable
+@env{OLDPWD}, if it is set, is substituted.
+
+If the characters following the tilde in the tilde-prefix consist of a
+number @var{N}, optionally prefixed by a @samp{+} or a @samp{-},
+the tilde-prefix is replaced with the
+corresponding element from the directory stack, as it would be displayed
+by the @code{dirs} builtin invoked with the characters following tilde
+in the tilde-prefix as an argument (@pxref{The Directory Stack}).
+If the tilde-prefix, sans the tilde, consists of a number without a
+leading @samp{+} or @samp{-}, @samp{+} is assumed.
+
+If the login name is invalid, or the tilde expansion fails, the word is
+left unchanged.
+
+Each variable assignment is checked for unquoted tilde-prefixes immediately
+following a @samp{:} or the first @samp{=}.
+In these cases, tilde expansion is also performed.
+Consequently, one may use filenames with tildes in assignments to
+@env{PATH}, @env{MAILPATH}, and @env{CDPATH},
+and the shell assigns the expanded value.
+
+The following table shows how Bash treats unquoted tilde-prefixes:
+
+@table @code
+@item ~
+The value of @code{$HOME}
+@item ~/foo
+@file{$HOME/foo}
+
+@item ~fred/foo
+The subdirectory @code{foo} of the home directory of the user
+@code{fred}
+
+@item ~+/foo
+@file{$PWD/foo}
+
+@item ~-/foo
+@file{$@{OLDPWD-'~-'@}/foo}
+
+@item ~@var{N}
+The string that would be displayed by @samp{dirs +@var{N}}
+
+@item ~+@var{N}
+The string that would be displayed by @samp{dirs +@var{N}}
+
+@item ~-@var{N}
+The string that would be displayed by @samp{dirs -@var{N}}
+@end table
+
+Bash also performs tilde expansion on words satisfying the conditions of
+variable assignments (@pxref{Shell Parameters})
+when they appear as arguments to simple commands.
+Bash does not do this, except for the declaration commands listed
+above, when in @sc{posix} mode.
+
+@node Shell Parameter Expansion
+@subsection Shell Parameter Expansion
+@cindex parameter expansion
+@cindex expansion, parameter
+
+The @samp{$} character introduces parameter expansion,
+command substitution, or arithmetic expansion.  The parameter name
+or symbol to be expanded may be enclosed in braces, which
+are optional but serve to protect the variable to be expanded from
+characters immediately following it which could be
+interpreted as part of the name.
+
+When braces are used, the matching ending brace is the first @samp{@}}
+not escaped by a backslash or within a quoted string, and not within an
+embedded arithmetic expansion, command substitution, or parameter
+expansion.
+
+The basic form of parameter expansion is $@{@var{parameter}@}.
+The value of @var{parameter} is substituted.
+The @var{parameter} is a shell parameter as described above
+(@pxref{Shell Parameters}) or an array reference (@pxref{Arrays}).
+The braces are required when @var{parameter}
+is a positional parameter with more than one digit,
+or when @var{parameter} is followed by a character that is not to be
+interpreted as part of its name.
+
+If the first character of @var{parameter} is an exclamation point (!),
+and @var{parameter} is not a nameref,
+it introduces a level of indirection.
+Bash uses the value formed by expanding the rest of
+@var{parameter} as the new @var{parameter}; this is then
+expanded and that value is used in the rest of the expansion, rather
+than the expansion of the original @var{parameter}.
+This is known as @code{indirect expansion}.
+The value is subject to tilde expansion,
+parameter expansion, command substitution, and arithmetic expansion.
+If @var{parameter} is a nameref, this expands to the name of the
+variable referenced by @var{parameter} instead of performing the
+complete indirect expansion.
+The exceptions to this are the expansions of $@{!@var{prefix}*@}
+and $@{!@var{name}[@@]@}
+described below.
+The exclamation point must immediately follow the left brace in order to
+introduce indirection.
+
+In each of the cases below, @var{word} is subject to tilde expansion,
+parameter expansion, command substitution, and arithmetic expansion.
+
+When not performing substring expansion, using the form described
+below (e.g., @samp{:-}), Bash tests for a parameter that is unset or null.
+Omitting the colon results in a test only for a parameter that is unset.
+Put another way, if the colon is included,
+the operator tests for both @var{parameter}'s existence and that its value
+is not null; if the colon is omitted, the operator tests only for existence.
+
+@table @code
+
+@item $@{@var{parameter}:@minus{}@var{word}@}
+If @var{parameter} is unset or null, the expansion of
+@var{word} is substituted.  Otherwise, the value of
+@var{parameter} is substituted.
+
+@example
+$ v=123
+$ echo $@{v-unset@}
+123
+@end example
+
+@item $@{@var{parameter}:=@var{word}@}
+If @var{parameter}
+is unset or null, the expansion of @var{word}
+is assigned to @var{parameter}.
+The value of @var{parameter} is then substituted. 
+Positional parameters and special parameters may not be assigned to
+in this way.
+
+@example
+$ var=
+$ : $@{var:=DEFAULT@}
+$ echo $var
+DEFAULT
+@end example
+
+@item $@{@var{parameter}:?@var{word}@}
+If @var{parameter}
+is null or unset, the expansion of @var{word} (or a message
+to that effect if @var{word}
+is not present) is written to the standard error and the shell, if it
+is not interactive, exits.  Otherwise, the value of @var{parameter} is
+substituted.
+
+@example
+$ var=
+$ : $@{var:?var is unset or null@}
+bash: var: var is unset or null
+@end example
+
+@item $@{@var{parameter}:+@var{word}@}
+If @var{parameter}
+is null or unset, nothing is substituted, otherwise the expansion of
+@var{word} is substituted.
+
+@example
+$ var=123
+$ echo $@{var:+var is set and not null@}
+var is set and not null
+@end example
+
+@item $@{@var{parameter}:@var{offset}@}
+@itemx $@{@var{parameter}:@var{offset}:@var{length}@}
+This is referred to as Substring Expansion.
+It expands to up to @var{length} characters of the value of @var{parameter}
+starting at the character specified by @var{offset}.
+If @var{parameter} is @samp{@@} or @samp{*}, an indexed array subscripted by
+@samp{@@} or @samp{*}, or an associative array name, the results differ as
+described below.
+If @var{length} is omitted, it expands to the substring of the value of
+@var{parameter} starting at the character specified by @var{offset}
+and extending to the end of the value.
+@var{length} and @var{offset} are arithmetic expressions
+(@pxref{Shell Arithmetic}).
+
+If @var{offset} evaluates to a number less than zero, the value
+is used as an offset in characters
+from the end of the value of @var{parameter}.
+If @var{length} evaluates to a number less than zero,
+it is interpreted as an offset in characters
+from the end of the value of @var{parameter} rather than
+a number of characters, and the expansion is the characters between
+@var{offset} and that result.
+Note that a negative offset must be separated from the colon by at least
+one space to avoid being confused with the @samp{:-} expansion.
+
+Here are some examples illustrating substring expansion on parameters and
+subscripted arrays:
+
+@verbatim
+$ string=01234567890abcdefgh
+$ echo ${string:7}
+7890abcdefgh
+$ echo ${string:7:0}
+
+$ echo ${string:7:2}
+78
+$ echo ${string:7:-2}
+7890abcdef
+$ echo ${string: -7}
+bcdefgh
+$ echo ${string: -7:0}
+
+$ echo ${string: -7:2}
+bc
+$ echo ${string: -7:-2}
+bcdef
+$ set -- 01234567890abcdefgh
+$ echo ${1:7}
+7890abcdefgh
+$ echo ${1:7:0}
+
+$ echo ${1:7:2}
+78
+$ echo ${1:7:-2}
+7890abcdef
+$ echo ${1: -7}
+bcdefgh
+$ echo ${1: -7:0}
+
+$ echo ${1: -7:2}
+bc
+$ echo ${1: -7:-2}
+bcdef
+$ array[0]=01234567890abcdefgh
+$ echo ${array[0]:7}
+7890abcdefgh
+$ echo ${array[0]:7:0}
+
+$ echo ${array[0]:7:2}
+78
+$ echo ${array[0]:7:-2}
+7890abcdef
+$ echo ${array[0]: -7}
+bcdefgh
+$ echo ${array[0]: -7:0}
+
+$ echo ${array[0]: -7:2}
+bc
+$ echo ${array[0]: -7:-2}
+bcdef
+@end verbatim
+
+If @var{parameter} is @samp{@@} or @samp{*}, the result is @var{length}
+positional parameters beginning at @var{offset}.
+A negative @var{offset} is taken relative to one greater than the greatest
+positional parameter, so an offset of -1 evaluates to the last positional
+parameter.
+It is an expansion error if @var{length} evaluates to a number less than zero.
+
+The following examples illustrate substring expansion using positional
+parameters:
+
+@verbatim
+$ set -- 1 2 3 4 5 6 7 8 9 0 a b c d e f g h
+$ echo ${@:7}
+7 8 9 0 a b c d e f g h
+$ echo ${@:7:0}
+
+$ echo ${@:7:2}
+7 8
+$ echo ${@:7:-2}
+bash: -2: substring expression < 0
+$ echo ${@: -7:2}
+b c
+$ echo ${@:0}
+./bash 1 2 3 4 5 6 7 8 9 0 a b c d e f g h
+$ echo ${@:0:2}
+./bash 1
+$ echo ${@: -7:0}
+
+@end verbatim
+
+If @var{parameter} is an indexed array name subscripted
+by @samp{@@} or @samp{*}, the result is the @var{length}
+members of the array beginning with @code{$@{@var{parameter}[@var{offset}]@}}.
+A negative @var{offset} is taken relative to one greater than the maximum
+index of the specified array.
+It is an expansion error if @var{length} evaluates to a number less than zero.
+
+These examples show how you can use substring expansion with indexed
+arrays:
+
+@verbatim
+$ array=(0 1 2 3 4 5 6 7 8 9 0 a b c d e f g h)
+$ echo ${array[@]:7}
+7 8 9 0 a b c d e f g h
+$ echo ${array[@]:7:2}
+7 8
+$ echo ${array[@]: -7:2}
+b c
+$ echo ${array[@]: -7:-2}
+bash: -2: substring expression < 0
+$ echo ${array[@]:0}
+0 1 2 3 4 5 6 7 8 9 0 a b c d e f g h
+$ echo ${array[@]:0:2}
+0 1
+$ echo ${array[@]: -7:0}
+
+@end verbatim
+
+Substring expansion applied to an associative array produces undefined
+results.
+
+Substring indexing is zero-based unless the positional parameters
+are used, in which case the indexing starts at 1 by default.
+If @var{offset} is 0, and the positional parameters are used, @code{$0} is
+prefixed to the list.
+
+@item $@{!@var{prefix}*@}
+@itemx $@{!@var{prefix}@@@}
+Expands to the names of variables whose names begin with @var{prefix},
+separated by the first character of the @env{IFS} special variable.
+When @samp{@@} is used and the expansion appears within double quotes, each
+variable name expands to a separate word.
+
+@item $@{!@var{name}[@@]@}
+@itemx $@{!@var{name}[*]@}
+If @var{name} is an array variable, expands to the list of array indices
+(keys) assigned in @var{name}.
+If @var{name} is not an array, expands to 0 if @var{name} is set and null
+otherwise.
+When @samp{@@} is used and the expansion appears within double quotes, each
+key expands to a separate word.
+
+@item $@{#@var{parameter}@}
+The length in characters of the expanded value of @var{parameter} is
+substituted.
+If @var{parameter} is @samp{*} or @samp{@@}, the value substituted
+is the number of positional parameters.
+If @var{parameter} is an array name subscripted by @samp{*} or @samp{@@}, 
+the value substituted is the number of elements in the array.
+If @var{parameter}
+is an indexed array name subscripted by a negative number, that number is
+interpreted as relative to one greater than the maximum index of
+@var{parameter}, so negative indices count back from the end of the
+array, and an index of -1 references the last element.
+
+@item $@{@var{parameter}#@var{word}@}
+@itemx $@{@var{parameter}##@var{word}@}
+The @var{word}
+is expanded to produce a pattern and matched according to the rules
+described below (@pxref{Pattern Matching}).  If the pattern matches
+the beginning of the expanded value of @var{parameter},
+then the result of the expansion is the expanded value of @var{parameter}
+with the shortest matching pattern (the @samp{#} case) or the
+longest matching pattern (the @samp{##} case) deleted.
+If @var{parameter} is @samp{@@} or @samp{*},
+the pattern removal operation is applied to each positional
+parameter in turn, and the expansion is the resultant list.
+If @var{parameter} is an array variable subscripted with
+@samp{@@} or @samp{*},
+the pattern removal operation is applied to each member of the
+array in turn, and the expansion is the resultant list.
+
+@item $@{@var{parameter}%@var{word}@}
+@itemx $@{@var{parameter}%%@var{word}@}
+The @var{word}
+is expanded to produce a pattern and matched according to the rules
+described below (@pxref{Pattern Matching}).
+If the pattern matches a trailing portion of the expanded value of
+@var{parameter}, then the result of the expansion is the value of
+@var{parameter} with the shortest matching pattern (the @samp{%} case)
+or the longest matching pattern (the @samp{%%} case) deleted.
+If @var{parameter} is @samp{@@} or @samp{*},
+the pattern removal operation is applied to each positional
+parameter in turn, and the expansion is the resultant list.
+If @var{parameter}
+is an array variable subscripted with @samp{@@} or @samp{*},
+the pattern removal operation is applied to each member of the
+array in turn, and the expansion is the resultant list.
+
+@item $@{@var{parameter}/@var{pattern}/@var{string}@} 
+@itemx $@{@var{parameter}//@var{pattern}/@var{string}@} 
+@itemx $@{@var{parameter}/#@var{pattern}/@var{string}@} 
+@itemx $@{@var{parameter}/%@var{pattern}/@var{string}@} 
+The @var{pattern} is expanded to produce a pattern just as in
+filename expansion.
+@var{Parameter} is expanded and the longest match of @var{pattern}
+against its value is replaced with @var{string}.
+@var{string} undergoes tilde expansion, parameter and variable expansion,
+arithmetic expansion, command and process substitution, and quote removal.
+The match is performed according to the rules described below
+(@pxref{Pattern Matching}).
+
+In the first form above, only the first match is replaced.
+If there are two slashes separating @var{parameter} and @var{pattern}
+(the second form above), all matches of @var{pattern} are
+replaced with @var{string}.
+If @var{pattern} is preceded by @samp{#} (the third form above),
+it must match at the beginning of the expanded value of @var{parameter}.
+If @var{pattern} is preceded by @samp{%} (the fourth form above),
+it must match at the end of the expanded value of @var{parameter}.
+If the expansion of @var{string} is null,
+matches of @var{pattern} are deleted.
+If @var{string} is null,
+matches of @var{pattern} are deleted
+and the @samp{/} following @var{pattern} may be omitted.
+
+If the @code{patsub_replacement} shell option is enabled using @code{shopt},
+any unquoted instances of @samp{&} in @var{string} are replaced with the
+matching portion of @var{pattern}.
+This is intended to duplicate a common @code{sed} idiom.
+
+Quoting any part of @var{string} inhibits replacement in the
+expansion of the quoted portion, including replacement strings stored
+in shell variables.
+Backslash will escape @samp{&} in @var{string}; the backslash is removed
+in order to permit a literal @samp{&} in the replacement string.
+Users should take care if @var{string} is double-quoted to avoid
+unwanted interactions between the backslash and double-quoting, since
+backslash has special meaning within double quotes.
+Pattern substitution performs the check for unquoted @samp{&} after
+expanding @var{string},
+so users should ensure to properly quote any occurrences of @samp{&}
+they want to be taken literally in the replacement
+and ensure any instances of @samp{&} they want to be replaced are unquoted.
+
+For instance,
+
+@example
+var=abcdef
+rep='& '
+echo $@{var/abc/& @}
+echo "$@{var/abc/& @}"
+echo $@{var/abc/$rep@}
+echo "$@{var/abc/$rep@}"
+@end example
+
+@noindent
+will display four lines of "abc def", while
+
+@example
+var=abcdef
+rep='& '
+echo $@{var/abc/\& @}
+echo "$@{var/abc/\& @}"
+echo $@{var/abc/"& "@}
+echo $@{var/abc/"$rep"@}
+@end example
+
+@noindent
+will display four lines of "& def".
+Like the pattern removal operators, double quotes surrounding the
+replacement string quote the expanded characters, while double quotes
+enclosing the entire parameter substitution do not, since
+the expansion is performed in a
+context that doesn't take any enclosing double quotes into account.
+
+Since backslash can escape @samp{&}, it can also escape a backslash in
+the replacement string.
+This means that @samp{\\} will insert a literal
+backslash into the replacement, so these two @code{echo} commands
+
+@example
+var=abcdef
+rep='\\&xyz'
+echo $@{var/abc/\\&xyz@}
+echo $@{var/abc/$rep@}
+@end example
+
+@noindent
+will both output @samp{\abcxyzdef}.
+
+It should rarely be necessary to enclose only @var{string} in double
+quotes.
+
+If the @code{nocasematch} shell option   
+(see the description of @code{shopt} in @ref{The Shopt Builtin})
+is enabled, the match is performed without regard to the case   
+of alphabetic characters.
+If @var{parameter} is @samp{@@} or @samp{*},
+the substitution operation is applied to each positional
+parameter in turn, and the expansion is the resultant list.
+If @var{parameter}
+is an array variable subscripted with @samp{@@} or @samp{*},
+the substitution operation is applied to each member of the
+array in turn, and the expansion is the resultant list.
+
+@item $@{@var{parameter}^@var{pattern}@}
+@itemx $@{@var{parameter}^^@var{pattern}@}
+@itemx $@{@var{parameter},@var{pattern}@}
+@itemx $@{@var{parameter},,@var{pattern}@}
+This expansion modifies the case of alphabetic characters in @var{parameter}.
+The @var{pattern} is expanded to produce a pattern just as in
+filename expansion.
+Each character in the expanded value of @var{parameter} is tested against
+@var{pattern}, and, if it matches the pattern, its case is converted.
+The pattern should not attempt to match more than one character.
+
+The @samp{^} operator converts lowercase letters matching @var{pattern}
+to uppercase; the @samp{,} operator converts matching uppercase letters
+to lowercase.
+The @samp{^^} and @samp{,,} expansions convert each matched character in the
+expanded value; the @samp{^} and @samp{,} expansions match and convert only
+the first character in the expanded value.
+If @var{pattern} is omitted, it is treated like a @samp{?}, which matches
+every character.
+
+If @var{parameter} is @samp{@@} or @samp{*},
+the case modification operation is applied to each positional
+parameter in turn, and the expansion is the resultant list.
+If @var{parameter}
+is an array variable subscripted with @samp{@@} or @samp{*},
+the case modification operation is applied to each member of the
+array in turn, and the expansion is the resultant list.
+
+@item $@{@var{parameter}@@@var{operator}@}
+The expansion is either a transformation of the value of @var{parameter}
+or information about @var{parameter} itself, depending on the value of
+@var{operator}.  Each @var{operator} is a single letter:
+
+@table @code
+@item U
+The expansion is a string that is the value of @var{parameter} with lowercase
+alphabetic characters converted to uppercase.
+@item u
+The expansion is a string that is the value of @var{parameter} with the first
+character converted to uppercase, if it is alphabetic.
+@item L
+The expansion is a string that is the value of @var{parameter} with uppercase
+alphabetic characters converted to lowercase.
+@item Q
+The expansion is a string that is the value of @var{parameter} quoted in a
+format that can be reused as input.
+@item E
+The expansion is a string that is the value of @var{parameter} with backslash
+escape sequences expanded as with the @code{$'@dots{}'} quoting mechanism.
+@item P
+The expansion is a string that is the result of expanding the value of
+@var{parameter} as if it were a prompt string (@pxref{Controlling the Prompt}).
+@item A
+The expansion is a string in the form of
+an assignment statement or @code{declare} command that, if
+evaluated, will recreate @var{parameter} with its attributes and value.
+@item K
+Produces a possibly-quoted version of the value of @var{parameter},
+except that it prints the values of
+indexed and associative arrays as a sequence of quoted key-value pairs
+(@pxref{Arrays}).
+@item a
+The expansion is a string consisting of flag values representing
+@var{parameter}'s attributes.
+@item k
+Like the @samp{K} transformation, but expands the keys and values of
+indexed and associative arrays to separate words after word splitting.
+@end table
+
+If @var{parameter} is @samp{@@} or @samp{*},
+the operation is applied to each positional
+parameter in turn, and the expansion is the resultant list.
+If @var{parameter}
+is an array variable subscripted with @samp{@@} or @samp{*},
+the operation is applied to each member of the
+array in turn, and the expansion is the resultant list.
+
+The result of the expansion is subject to word splitting and filename
+expansion as described below.
+@end table
+
+@node Command Substitution
+@subsection Command Substitution
+@cindex command substitution
+
+Command substitution allows the output of a command to replace
+the command itself.
+Command substitution occurs when a command is enclosed as follows:
+@example
+$(@var{command})
+@end example
+@noindent
+or
+@example
+`@var{command}`
+@end example
+
+@noindent
+Bash performs the expansion by executing @var{command} in a subshell environment
+and replacing the command substitution with the standard output of the
+command, with any trailing newlines deleted.
+Embedded newlines are not deleted, but they may be removed during
+word splitting.
+The command substitution @code{$(cat @var{file})} can be
+replaced by the equivalent but faster @code{$(< @var{file})}.
+
+When the old-style backquote form of substitution is used,
+backslash retains its literal meaning except when followed by
+@samp{$}, @samp{`}, or @samp{\}. 
+The first backquote not preceded by a backslash terminates the
+command substitution.
+When using the @code{$(@var{command})} form, all characters between
+the parentheses make up the command; none are treated specially.
+
+Command substitutions may be nested.  To nest when using the backquoted
+form, escape the inner backquotes with backslashes.
+
+If the substitution appears within double quotes, word splitting and
+filename expansion are not performed on the results.
+
+@node Arithmetic Expansion
+@subsection Arithmetic Expansion
+@cindex expansion, arithmetic
+@cindex arithmetic expansion
+
+Arithmetic expansion allows the evaluation of an arithmetic expression
+and the substitution of the result.  The format for arithmetic expansion is:
+
+@example
+$(( @var{expression} ))
+@end example
+
+The @var{expression} undergoes the same expansions
+as if it were within double quotes,
+but double quote characters in @var{expression} are not treated specially
+and are removed.
+All tokens in the expression undergo parameter and variable expansion,
+command substitution, and quote removal.
+The result is treated as the arithmetic expression to be evaluated.
+Arithmetic expansions may be nested. 
+
+The evaluation is performed according to the rules listed below
+(@pxref{Shell Arithmetic}).
+If the expression is invalid, Bash prints a message indicating
+failure to the standard error and no substitution occurs.
+
+@node Process Substitution
+@subsection Process Substitution
+@cindex process substitution
+
+Process substitution allows a process's input or output to be
+referred to using a filename.
+It takes the form of 
+@example
+<(@var{list})
+@end example
+@noindent
+or
+@example
+>(@var{list})
+@end example
+@noindent
+The process @var{list} is run asynchronously, and its input or output 
+appears as a filename.
+This filename is
+passed as an argument to the current command as the result of the
+expansion.
+If the @code{>(@var{list})} form is used, writing to
+the file will provide input for @var{list}.  If the
+@code{<(@var{list})} form is used, the file passed as an
+argument should be read to obtain the output of @var{list}.
+Note that no space may appear between the @code{<} or @code{>}
+and the left parenthesis, otherwise the construct would be interpreted
+as a redirection.
+Process substitution is supported on systems that support named
+pipes (@sc{fifo}s) or the @file{/dev/fd} method of naming open files.
+
+When available, process substitution is performed simultaneously with
+parameter and variable expansion, command substitution, and arithmetic
+expansion.
+
+@node Word Splitting
+@subsection Word Splitting
+@cindex word splitting
+
+The shell scans the results of parameter expansion, command substitution,
+and arithmetic expansion that did not occur within double quotes for
+word splitting.
+
+The shell treats each character of @env{$IFS} as a delimiter, and splits
+the results of the other expansions into words using these characters
+as field terminators.
+If @env{IFS} is unset, or its value is exactly @code{<space><tab><newline>},
+the default, then sequences of
+@code{ <space>}, @code{<tab>}, and @code{<newline>}
+at the beginning and end of the results of the previous
+expansions are ignored, and any sequence of @env{IFS}
+characters not at the beginning or end serves to delimit words.
+If @env{IFS} has a value other than the default, then sequences of
+the whitespace characters @code{space}, @code{tab}, and @code{newline}
+are ignored at the beginning and end of the
+word, as long as the whitespace character is in the
+value of @env{IFS} (an @env{IFS} whitespace character).
+Any character in @env{IFS} that is not @env{IFS}
+whitespace, along with any adjacent @env{IFS}
+whitespace characters, delimits a field.  A sequence of @env{IFS}
+whitespace characters is also treated as a delimiter.
+If the value of @env{IFS} is null, no word splitting occurs.
+
+Explicit null arguments (@code{""} or @code{''}) are retained
+and passed to commands as empty strings.
+Unquoted implicit null arguments, resulting from the expansion of
+parameters that have no values, are removed.
+If a parameter with no value is expanded within double quotes, a
+null argument results and is retained
+and passed to a command as an empty string.
+When a quoted null argument appears as part of a word whose expansion is
+non-null, the null argument is removed.
+That is, the word
+@code{-d''} becomes @code{-d} after word splitting and
+null argument removal.
+
+Note that if no expansion occurs, no splitting
+is performed.
+
+@node Filename Expansion
+@subsection Filename Expansion
+@menu
+* Pattern Matching::	How the shell matches patterns.
+@end menu
+@cindex expansion, filename
+@cindex expansion, pathname
+@cindex filename expansion
+@cindex pathname expansion
+
+After word splitting, unless the @option{-f} option has been set
+(@pxref{The Set Builtin}), Bash scans each word for the characters
+@samp{*}, @samp{?}, and @samp{[}.
+If one of these characters appears, and is not quoted, then the word is
+regarded as a @var{pattern},
+and replaced with an alphabetically sorted list of
+filenames matching the pattern (@pxref{Pattern Matching}).
+If no matching filenames are found,
+and the shell option @code{nullglob} is disabled, the word is left
+unchanged.
+If the @code{nullglob} option is set, and no matches are found, the word
+is removed.
+If the @code{failglob} shell option is set, and no matches are found,
+an error message is printed and the command is not executed.
+If the shell option @code{nocaseglob} is enabled, the match is performed
+without regard to the case of alphabetic characters.
+
+When a pattern is used for filename expansion, the character @samp{.}
+at the start of a filename or immediately following a slash
+must be matched explicitly, unless the shell option @code{dotglob} is set.
+In order to match the filenames @samp{.} and @samp{..},
+the pattern must begin with @samp{.} (for example, @samp{.?}),
+even if @code{dotglob} is set.
+If the @code{globskipdots} shell option is enabled, the filenames
+@samp{.} and @samp{..} are never matched, even if the pattern begins
+with a @samp{.}.
+When not matching filenames, the @samp{.} character is not treated specially.
+
+When matching a filename, the slash character must always be
+matched explicitly by a slash in the pattern, but in other matching
+contexts it can be matched by a special pattern character as described
+below (@pxref{Pattern Matching}).
+
+See the description of @code{shopt} in @ref{The Shopt Builtin},
+for a description of the @code{nocaseglob}, @code{nullglob},
+@code{globskipdots},
+@code{failglob}, and @code{dotglob} options.
+
+The @env{GLOBIGNORE}
+shell variable may be used to restrict the set of file names matching a
+pattern.  If @env{GLOBIGNORE}
+is set, each matching file name that also matches one of the patterns in
+@env{GLOBIGNORE} is removed from the list of matches.
+If the @code{nocaseglob} option is set, the matching against the patterns in
+@env{GLOBIGNORE} is performed without regard to case.
+The filenames
+@file{.} and @file{..}
+are always ignored when @env{GLOBIGNORE}
+is set and not null.
+However, setting @env{GLOBIGNORE} to a non-null value has the effect of
+enabling the @code{dotglob}
+shell option, so all other filenames beginning with a
+@samp{.} will match.
+To get the old behavior of ignoring filenames beginning with a
+@samp{.}, make @samp{.*} one of the patterns in @env{GLOBIGNORE}.
+The @code{dotglob} option is disabled when @env{GLOBIGNORE}
+is unset.
+
+@node Pattern Matching
+@subsubsection Pattern Matching
+@cindex pattern matching
+@cindex matching, pattern
+
+Any character that appears in a pattern, other than the special pattern
+characters described below, matches itself.
+The @sc{nul} character may not occur in a pattern.
+A backslash escapes the following character; the
+escaping backslash is discarded when matching.
+The special pattern characters must be quoted if they are to be matched
+literally.
+
+The special pattern characters have the following meanings:
+@table @code
+@item *
+Matches any string, including the null string.
+When the @code{globstar} shell option is enabled, and @samp{*} is used in
+a filename expansion context, two adjacent @samp{*}s used as a single
+pattern will match all files and zero or more directories and
+subdirectories.
+If followed by a @samp{/}, two adjacent @samp{*}s will match only
+directories and subdirectories.
+@item ?
+Matches any single character.
+@item [@dots{}]
+Matches any one of the enclosed characters.  A pair of characters
+separated by a hyphen denotes a @var{range expression};
+any character that falls between those two characters, inclusive,
+using the current locale's collating sequence and character set,
+is matched.  If the first character following the
+@samp{[} is a @samp{!}  or a @samp{^}
+then any character not enclosed is matched.  A @samp{@minus{}}
+may be matched by including it as the first or last character
+in the set.  A @samp{]} may be matched by including it as the first
+character in the set.
+The sorting order of characters in range expressions,
+and the characters included in the range,
+are determined by
+the current locale and the values of the
+@env{LC_COLLATE} and @env{LC_ALL} shell variables, if set.
+
+For example, in the default C locale, @samp{[a-dx-z]} is equivalent to
+@samp{[abcdxyz]}.  Many locales sort characters in dictionary order, and in
+these locales @samp{[a-dx-z]} is typically not equivalent to @samp{[abcdxyz]};
+it might be equivalent to @samp{[aBbCcDdxYyZz]}, for example.  To obtain
+the traditional interpretation of ranges in bracket expressions, you can
+force the use of the C locale by setting the @env{LC_COLLATE} or
+@env{LC_ALL} environment variable to the value @samp{C}, or enable the
+@code{globasciiranges} shell option.
+
+Within @samp{[} and @samp{]}, @dfn{character classes} can be specified
+using the syntax
+@code{[:}@var{class}@code{:]}, where @var{class} is one of the
+following classes defined in the @sc{posix} standard:
+@example
+alnum   alpha   ascii   blank   cntrl   digit   graph   lower
+print   punct   space   upper   word    xdigit
+@end example
+@noindent
+A character class matches any character belonging to that class.
+The @code{word} character class matches letters, digits, and the character
+@samp{_}.
+
+Within @samp{[} and @samp{]}, an @dfn{equivalence class} can be
+specified using the syntax @code{[=}@var{c}@code{=]}, which
+matches all characters with the same collation weight (as defined
+by the current locale) as the character @var{c}.
+
+Within @samp{[} and @samp{]}, the syntax @code{[.}@var{symbol}@code{.]}
+matches the collating symbol @var{symbol}.
+@end table
+
+If the @code{extglob} shell option is enabled using the @code{shopt}
+builtin, the shell recognizes several extended pattern matching operators.
+In the following description, a @var{pattern-list} is a list of one
+or more patterns separated by a @samp{|}.
+When matching filenames, the @code{dotglob} shell option determines
+the set of filenames that are tested, as described above.
+Composite patterns may be formed using one or more of the following
+sub-patterns:
+
+@table @code
+@item ?(@var{pattern-list})
+Matches zero or one occurrence of the given patterns.
+
+@item *(@var{pattern-list})
+Matches zero or more occurrences of the given patterns.
+
+@item +(@var{pattern-list})
+Matches one or more occurrences of the given patterns.
+
+@item @@(@var{pattern-list})
+Matches one of the given patterns.
+
+@item !(@var{pattern-list})
+Matches anything except one of the given patterns.
+@end table
+
+The @code{extglob} option changes the behavior of the parser, since the
+parentheses are normally treated as operators with syntactic meaning.
+To ensure that extended matching patterns are parsed correctly, make sure
+that @code{extglob} is enabled before parsing constructs containing the
+patterns, including shell functions and command substitutions.
+
+When matching filenames, the @code{dotglob} shell option determines
+the set of filenames that are tested:
+when @code{dotglob} is enabled, the set of filenames includes all files
+beginning with @samp{.}, but the filenames
+@samp{.} and @samp{..} must be matched by a
+pattern or sub-pattern that begins with a dot;
+when it is disabled, the set does not
+include any filenames beginning with ``.'' unless the pattern
+or sub-pattern begins with a @samp{.}.
+As above, @samp{.} only has a special meaning when matching filenames. 
+
+Complicated extended pattern matching against long strings is slow,
+especially when the patterns contain alternations and the strings
+contain multiple matches.
+Using separate matches against shorter strings, or using arrays of
+strings instead of a single long string, may be faster.
+
+@node Quote Removal
+@subsection Quote Removal
+
+After the preceding expansions, all unquoted occurrences of the
+characters @samp{\}, @samp{'}, and @samp{"} that did not
+result from one of the above expansions are removed.
+
+@node Redirections
+@section Redirections
+@cindex redirection
+
+Before a command is executed, its input and output
+may be @dfn{redirected}
+using a special notation interpreted by the shell.
+@dfn{Redirection} allows commands' file handles to be
+duplicated, opened, closed,
+made to refer to different files,
+and can change the files the command reads from and writes to.
+Redirection may also be used to modify file handles in the
+current shell execution environment.  The following redirection
+operators may precede or appear anywhere within a
+simple command or may follow a command.
+Redirections are processed in the order they appear, from
+left to right.
+
+Each redirection that may be preceded by a file descriptor number
+may instead be preceded by a word of the form @{@var{varname}@}.
+In this case, for each redirection operator except
+>&- and <&-, the shell will allocate a file descriptor greater
+than 10 and assign it to @{@var{varname}@}.  If >&- or <&- is preceded
+by @{@var{varname}@}, the value of @var{varname} defines the file
+descriptor to close.
+If @{@var{varname}@} is supplied, the redirection persists beyond
+the scope of the command, allowing the shell programmer to manage
+the file descriptor's lifetime manually.
+The @code{varredir_close} shell option manages this behavior
+(@pxref{The Shopt Builtin}).
+
+In the following descriptions, if the file descriptor number is
+omitted, and the first character of the redirection operator is
+@samp{<}, the redirection refers to the standard input (file
+descriptor 0).  If the first character of the redirection operator
+is @samp{>}, the redirection refers to the standard output (file
+descriptor 1).
+
+The word following the redirection operator in the following
+descriptions, unless otherwise noted, is subjected to brace expansion,
+tilde expansion, parameter expansion, command substitution, arithmetic
+expansion, quote removal, filename expansion, and word splitting.
+If it expands to more than one word, Bash reports an error.
+
+Note that the order of redirections is significant.  For example,
+the command
+@example
+ls > @var{dirlist} 2>&1
+@end example
+@noindent
+directs both standard output (file descriptor 1) and standard error
+(file descriptor 2) to the file @var{dirlist}, while the command
+@example
+ls 2>&1 > @var{dirlist}
+@end example
+@noindent
+directs only the standard output to file @var{dirlist},
+because the standard error was made a copy of the standard output
+before the standard output was redirected to @var{dirlist}.
+
+Bash handles several filenames specially when they are used in
+redirections, as described in the following table.
+If the operating system on which Bash is running provides these
+special files, bash will use them; otherwise it will emulate them
+internally with the behavior described below.
+
+@table @code
+@item /dev/fd/@var{fd}
+If @var{fd} is a valid integer, file descriptor @var{fd} is duplicated.
+
+@item /dev/stdin
+File descriptor 0 is duplicated.
+
+@item /dev/stdout
+File descriptor 1 is duplicated.
+
+@item /dev/stderr
+File descriptor 2 is duplicated.
+
+@item /dev/tcp/@var{host}/@var{port}
+If @var{host} is a valid hostname or Internet address, and @var{port}
+is an integer port number or service name, Bash attempts to open
+the corresponding TCP socket.
+
+@item /dev/udp/@var{host}/@var{port}
+If @var{host} is a valid hostname or Internet address, and @var{port}
+is an integer port number or service name, Bash attempts to open 
+the corresponding UDP socket.
+@end table
+
+A failure to open or create a file causes the redirection to fail.
+
+Redirections using file descriptors greater than 9 should be used with
+care, as they may conflict with file descriptors the shell uses
+internally.
+
+@subsection Redirecting Input
+Redirection of input causes the file whose name results from
+the expansion of @var{word}
+to be opened for reading on file descriptor @code{n},
+or the standard input (file descriptor 0) if @code{n}
+is not specified.
+
+The general format for redirecting input is:
+@example
+[@var{n}]<@var{word}
+@end example
+
+@subsection Redirecting Output
+Redirection of output causes the file whose name results from
+the expansion of @var{word}
+to be opened for writing on file descriptor @var{n},
+or the standard output (file descriptor 1) if @var{n}
+is not specified.  If the file does not exist it is created;
+if it does exist it is truncated to zero size.
+
+The general format for redirecting output is:
+@example
+[@var{n}]>[|]@var{word}
+@end example
+
+If the redirection operator is @samp{>}, and the @code{noclobber}
+option to the @code{set} builtin has been enabled, the redirection
+will fail if the file whose name results from the expansion of
+@var{word} exists and is a regular file.
+If the redirection operator is @samp{>|}, or the redirection operator is
+@samp{>} and the @code{noclobber} option is not enabled, the redirection
+is attempted even if the file named by @var{word} exists.
+
+@subsection Appending Redirected Output
+Redirection of output in this fashion
+causes the file whose name results from
+the expansion of @var{word}
+to be opened for appending on file descriptor @var{n},
+or the standard output (file descriptor 1) if @var{n}
+is not specified.  If the file does not exist it is created.
+
+The general format for appending output is:
+@example
+[@var{n}]>>@var{word}
+@end example
+
+@subsection Redirecting Standard Output and Standard Error
+This construct allows both the
+standard output (file descriptor 1) and
+the standard error output (file descriptor 2)
+to be redirected to the file whose name is the
+expansion of @var{word}.
+
+There are two formats for redirecting standard output and
+standard error:
+@example
+&>@var{word}
+@end example
+@noindent
+and
+@example
+>&@var{word}
+@end example
+@noindent
+Of the two forms, the first is preferred.
+This is semantically equivalent to
+@example
+>@var{word} 2>&1
+@end example
+When using the second form, @var{word} may not expand to a number or
+@samp{-}.  If it does, other redirection operators apply
+(see Duplicating File Descriptors below) for compatibility reasons.
+
+@subsection Appending Standard Output and Standard Error
+This construct allows both the
+standard output (file descriptor 1) and
+the standard error output (file descriptor 2)
+to be appended to the file whose name is the
+expansion of @var{word}.
+
+The format for appending standard output and standard error is:
+@example
+&>>@var{word}
+@end example
+@noindent
+This is semantically equivalent to
+@example
+>>@var{word} 2>&1
+@end example
+(see Duplicating File Descriptors below).
+
+@subsection Here Documents
+This type of redirection instructs the shell to read input from the
+current source until a line containing only @var{word}
+(with no trailing blanks) is seen.  All of
+the lines read up to that point are then used as the standard
+input (or file descriptor @var{n} if @var{n} is specified) for a command.
+
+The format of here-documents is:
+@example
+[@var{n}]<<[@minus{}]@var{word}
+        @var{here-document}
+@var{delimiter}
+@end example
+
+No parameter and variable expansion, command substitution,
+arithmetic expansion, or filename expansion is performed on
+@var{word}.  If any part of @var{word} is quoted, the
+@var{delimiter} is the result of quote removal on @var{word},
+and the lines in the here-document are not expanded.
+If @var{word} is unquoted,
+all lines of the here-document are subjected to
+parameter expansion, command substitution, and arithmetic expansion,
+the character sequence @code{\newline} is ignored, and @samp{\}
+must be used to quote the characters
+@samp{\}, @samp{$}, and @samp{`}.
+
+If the redirection operator is @samp{<<-},
+then all leading tab characters are stripped from input lines and the
+line containing @var{delimiter}.
+This allows here-documents within shell scripts to be indented in a
+natural fashion.
+
+@subsection Here Strings
+A variant of here documents, the format is:
+@example
+[@var{n}]<<< @var{word}
+@end example
+
+The @var{word} undergoes
+tilde expansion, parameter and variable expansion,
+command substitution, arithmetic expansion, and quote removal.
+Filename expansion and word splitting are not performed.
+The result is supplied as a single string,
+with a newline appended,
+to the command on its
+standard input (or file descriptor @var{n} if @var{n} is specified).
+
+@subsection Duplicating File Descriptors
+The redirection operator
+@example
+[@var{n}]<&@var{word}
+@end example
+@noindent
+is used to duplicate input file descriptors.
+If @var{word}
+expands to one or more digits, the file descriptor denoted by @var{n}
+is made to be a copy of that file descriptor.
+If the digits in @var{word} do not specify a file descriptor open for
+input, a redirection error occurs.
+If @var{word}
+evaluates to @samp{-}, file descriptor @var{n} is closed.
+If @var{n} is not specified, the standard input (file descriptor 0) is used.
+
+The operator
+@example
+[@var{n}]>&@var{word}
+@end example
+@noindent
+is used similarly to duplicate output file descriptors.  If
+@var{n} is not specified, the standard output (file descriptor 1) is used.
+If the digits in @var{word} do not specify a file descriptor open for
+output, a redirection error occurs.
+If @var{word}
+evaluates to @samp{-}, file descriptor @var{n} is closed.
+As a special case, if @var{n} is omitted, and @var{word} does not
+expand to one or more digits or @samp{-}, the standard output and standard
+error are redirected as described previously.
+
+@subsection Moving File Descriptors
+The redirection operator
+@example
+[@var{n}]<&@var{digit}-
+@end example
+@noindent
+moves the file descriptor @var{digit} to file descriptor @var{n},
+or the standard input (file descriptor 0) if @var{n} is not specified.
+@var{digit} is closed after being duplicated to @var{n}.
+
+Similarly, the redirection operator
+@example
+[@var{n}]>&@var{digit}-
+@end example
+@noindent
+moves the file descriptor @var{digit} to file descriptor @var{n},
+or the standard output (file descriptor 1) if @var{n} is not specified.
+
+@subsection Opening File Descriptors for Reading and Writing
+The redirection operator
+@example
+[@var{n}]<>@var{word}
+@end example
+@noindent
+causes the file whose name is the expansion of @var{word}
+to be opened for both reading and writing on file descriptor
+@var{n}, or on file descriptor 0 if @var{n}
+is not specified.  If the file does not exist, it is created.

+@node Simple Command Expansion
+@subsection Simple Command Expansion
+@cindex command expansion
+
+When a simple command is executed, the shell performs the following
+expansions, assignments, and redirections, from left to right, in
+the following order.
+
+@enumerate
+@item
+The words that the parser has marked as variable assignments (those
+preceding the command name) and redirections are saved for later
+processing.
+
+@item
+The words that are not variable assignments or redirections are
+expanded (@pxref{Shell Expansions}).
+If any words remain after expansion, the first word
+is taken to be the name of the command and the remaining words are
+the arguments.
+
+@item
+Redirections are performed as described above (@pxref{Redirections}).
+
+@item
+The text after the @samp{=} in each variable assignment undergoes tilde
+expansion, parameter expansion, command substitution, arithmetic expansion,
+and quote removal before being assigned to the variable.
+@end enumerate
+
+If no command name results, the variable assignments affect the current
+shell environment.
+In the case of such a command (one that consists only of assignment
+statements and redirections), assignment statements are performed before
+redirections.
+Otherwise, the variables are added to the environment
+of the executed command and do not affect the current shell environment.
+If any of the assignments attempts to assign a value to a readonly variable,
+an error occurs, and the command exits with a non-zero status.
+
+If no command name results, redirections are performed, but do not
+affect the current shell environment.  A redirection error causes the
+command to exit with a non-zero status.
+
+If there is a command name left after expansion, execution proceeds as
+described below.  Otherwise, the command exits.  If one of the expansions
+contained a command substitution, the exit status of the command is
+the exit status of the last command substitution performed.  If there
+were no command substitutions, the command exits with a status of zero.
+
+@node Command Search and Execution
+@subsection Command Search and Execution
+@cindex command execution
+@cindex command search
+
+After a command has been split into words, if it results in a
+simple command and an optional list of arguments, the following
+actions are taken.
+
+@enumerate
+@item
+If the command name contains no slashes, the shell attempts to
+locate it.  If there exists a shell function by that name, that
+function is invoked as described in @ref{Shell Functions}.
+
+@item
+If the name does not match a function, the shell searches for
+it in the list of shell builtins.  If a match is found, that
+builtin is invoked.
+
+@item
+If the name is neither a shell function nor a builtin,
+and contains no slashes, Bash searches each element of
+@env{$PATH} for a directory containing an executable file
+by that name.  Bash uses a hash table to remember the full
+pathnames of executable files to avoid multiple @env{PATH} searches
+(see the description of @code{hash} in @ref{Bourne Shell Builtins}).
+A full search of the directories in @env{$PATH}
+is performed only if the command is not found in the hash table.
+If the search is unsuccessful, the shell searches for a defined shell
+function named @code{command_not_found_handle}.
+If that function exists, it is invoked in a separate execution environment
+with the original command and
+the original command's arguments as its arguments, and the function's
+exit status becomes the exit status of that subshell.
+If that function is not defined, the shell prints an error
+message and returns an exit status of 127.
+
+@item
+If the search is successful, or if the command name contains
+one or more slashes, the shell executes the named program in
+a separate execution environment.
+Argument 0 is set to the name given, and the remaining arguments
+to the command are set to the arguments supplied, if any.
+
+@item
+If this execution fails because the file is not in executable
+format, and the file is not a directory, it is assumed to be a
+@dfn{shell script} and the shell executes it as described in
+@ref{Shell Scripts}.
+
+@item
+If the command was not begun asynchronously, the shell waits for
+the command to complete and collects its exit status.
+
+@end enumerate
+
+@node Command Execution Environment
+@subsection Command Execution Environment
+@cindex execution environment
+
+The shell has an @dfn{execution environment}, which consists of the
+following:
+
+@itemize @bullet
+@item
+open files inherited by the shell at invocation, as modified by
+redirections supplied to the @code{exec} builtin
+
+@item
+the current working directory as set by @code{cd}, @code{pushd}, or
+@code{popd}, or inherited by the shell at invocation
+
+@item
+the file creation mode mask as set by @code{umask} or inherited from
+the shell's parent
+
+@item
+current traps set by @code{trap}
+
+@item
+shell parameters that are set by variable assignment or with @code{set}
+or inherited from the shell's parent in the environment
+
+@item
+shell functions defined during execution or inherited from the shell's
+parent in the environment
+
+@item
+options enabled at invocation (either by default or with command-line
+arguments) or by @code{set}
+
+@item
+options enabled by @code{shopt} (@pxref{The Shopt Builtin})
+
+@item
+shell aliases defined with @code{alias} (@pxref{Aliases})
+
+@item
+various process @sc{id}s, including those of background jobs
+(@pxref{Lists}), the value of @code{$$}, and the value of
+@env{$PPID}
+
+@end itemize
+
+When a simple command other than a builtin or shell function
+is to be executed, it
+is invoked in a separate execution environment that consists of
+the following.  Unless otherwise noted, the values are inherited
+from the shell.
+
+@itemize @bullet
+@item
+the shell's open files, plus any modifications and additions specified
+by redirections to the command
+
+@item
+the current working directory
+
+@item
+the file creation mode mask
+
+@item
+shell variables and functions marked for export, along with variables
+exported for the command, passed in the environment (@pxref{Environment})
+
+@item
+traps caught by the shell are reset to the values inherited from the
+shell's parent, and traps ignored by the shell are ignored
+
+@end itemize
+
+A command invoked in this separate environment cannot affect the
+shell's execution environment.
+
+A @dfn{subshell} is a copy of the shell process.
+
+Command substitution, commands grouped with parentheses,
+and asynchronous commands are invoked in a
+subshell environment that is a duplicate of the shell environment,
+except that traps caught by the shell are reset to the values
+that the shell inherited from its parent at invocation.  Builtin
+commands that are invoked as part of a pipeline are also executed
+in a subshell environment.  Changes made to the subshell environment
+cannot affect the shell's execution environment.
+
+Subshells spawned to execute command substitutions inherit the value of
+the @option{-e} option from the parent shell.  When not in @sc{posix} mode,
+Bash clears the @option{-e} option in such subshells.
+
+If a command is followed by a @samp{&} and job control is not active, the
+default standard input for the command is the empty file @file{/dev/null}.
+Otherwise, the invoked command inherits the file descriptors of the calling
+shell as modified by redirections.
+
+@node Environment
+@subsection Environment
+@cindex environment
+
+When a program is invoked it is given an array of strings
+called the @dfn{environment}.
+This is a list of name-value pairs, of the form @code{name=value}.
+
+Bash provides several ways to manipulate the environment.
+On invocation, the shell scans its own environment and
+creates a parameter for each name found, automatically marking
+it for @code{export}
+to child processes.  Executed commands inherit the environment.
+The @code{export} and @samp{declare -x}
+commands allow parameters and functions to be added to and
+deleted from the environment.  If the value of a parameter
+in the environment is modified, the new value becomes part
+of the environment, replacing the old.  The environment
+inherited by any executed command consists of the shell's
+initial environment, whose values may be modified in the shell,
+less any pairs removed by the @code{unset} and @samp{export -n}
+commands, plus any additions via the @code{export} and
+@samp{declare -x} commands.
+
+The environment for any simple command
+or function may be augmented temporarily by prefixing it with
+parameter assignments, as described in @ref{Shell Parameters}.
+These assignment statements affect only the environment seen
+by that command.
+
+If the @option{-k} option is set (@pxref{The Set Builtin}), then all
+parameter assignments are placed in the environment for a command,
+not just those that precede the command name.
+
+When Bash invokes an external command, the variable @samp{$_}
+is set to the full pathname of the command and passed to that
+command in its environment.
+
+@node Exit Status
+@subsection Exit Status
+@cindex exit status
+
+The exit status of an executed command is the value returned by the
+@code{waitpid} system call or equivalent function.  Exit statuses    
+fall between 0 and 255, though, as explained below, the shell may
+use values above 125 specially.  Exit statuses from shell builtins and
+compound commands are also limited to this range.  Under certain
+circumstances, the shell will use special values to indicate specific
+failure modes.
+
+For the shell's purposes, a command which exits with a
+zero exit status has succeeded.
+A non-zero exit status indicates failure.
+This seemingly counter-intuitive scheme is used so there
+is one well-defined way to indicate success and a variety of
+ways to indicate various failure modes.
+When a command terminates on a fatal signal whose number is @var{N},
+Bash uses the value 128+@var{N} as the exit status.
+
+If a command is not found, the child process created to
+execute it returns a status of 127.  If a command is found  
+but is not executable, the return status is 126.
+
+If a command fails because of an error during expansion or redirection,
+the exit status is greater than zero.
+
+The exit status is used by the Bash conditional commands
+(@pxref{Conditional Constructs}) and some of the list
+constructs (@pxref{Lists}).
+
+All of the Bash builtins return an exit status of zero if they succeed
+and a non-zero status on failure, so they may be used by the
+conditional and list constructs.
+All builtins return an exit status of 2 to indicate incorrect usage,
+generally invalid options or missing arguments.
+
+The exit status of the last command is available in the special
+parameter $? (@pxref{Special Parameters}).
+
+@node Signals
+@subsection Signals
+@cindex signal handling
+
+When Bash is interactive, in the absence of any traps, it ignores
+@code{SIGTERM} (so that @samp{kill 0} does not kill an interactive shell),
+and @code{SIGINT}
+is caught and handled (so that the @code{wait} builtin is interruptible).
+When Bash receives a @code{SIGINT}, it breaks out of any executing loops.
+In all cases, Bash ignores @code{SIGQUIT}.
+If job control is in effect (@pxref{Job Control}), Bash
+ignores @code{SIGTTIN}, @code{SIGTTOU}, and @code{SIGTSTP}.
+
+Non-builtin commands started by Bash have signal handlers set to the
+values inherited by the shell from its parent.
+When job control is not in effect, asynchronous commands
+ignore @code{SIGINT} and @code{SIGQUIT} in addition to these inherited
+handlers.
+Commands run as a result of
+command substitution ignore the keyboard-generated job control signals
+@code{SIGTTIN}, @code{SIGTTOU}, and @code{SIGTSTP}.
+
+The shell exits by default upon receipt of a @code{SIGHUP}.
+Before exiting, an interactive shell resends the @code{SIGHUP} to
+all jobs, running or stopped.
+Stopped jobs are sent @code{SIGCONT} to ensure that they receive
+the @code{SIGHUP}.
+To prevent the shell from sending the @code{SIGHUP} signal to a
+particular job, it should be removed
+from the jobs table with the @code{disown}
+builtin (@pxref{Job Control Builtins}) or marked
+to not receive @code{SIGHUP} using @code{disown -h}.
+
+If the  @code{huponexit} shell option has been set with @code{shopt}
+(@pxref{The Shopt Builtin}), Bash sends a @code{SIGHUP} to all jobs when
+an interactive login shell exits.
+
+If Bash is waiting for a command to complete and receives a signal
+for which a trap has been set, the trap will not be executed until
+the command completes.
+When Bash is waiting for an asynchronous
+command via the @code{wait} builtin, the reception of a signal for
+which a trap has been set will cause the @code{wait} builtin to return
+immediately with an exit status greater than 128, immediately after
+which the trap is executed.
+
+When job control is not enabled, and Bash is waiting for a foreground
+command to complete, the shell receives keyboard-generated signals
+such as @code{SIGINT} (usually generated by @samp{^C}) that users
+commonly intend to send to that command.
+This happens because the shell and the command are in the same process
+group as the terminal, and @samp{^C} sends @code{SIGINT} to all processes
+in that process group.
+See @ref{Job Control}, for a more in-depth discussion of process groups.
+
+When Bash is running without job control enabled and receives @code{SIGINT}
+while waiting for a foreground command, it waits until that foreground
+command terminates and then decides what to do about the @code{SIGINT}:
+
+@enumerate
+@item
+If the command terminates due to the @code{SIGINT}, Bash concludes
+that the user meant to end the entire script, and acts on the
+@code{SIGINT} (e.g., by running a @code{SIGINT} trap or exiting itself);
+
+@item
+If the pipeline does not terminate due to @code{SIGINT}, the program
+handled the @code{SIGINT} itself and did not treat it as a fatal signal.
+In that case, Bash does not treat @code{SIGINT} as a fatal signal,
+either, instead assuming that the @code{SIGINT} was used as part of the
+program's normal operation (e.g., @command{emacs} uses it to abort editing
+commands) or deliberately discarded. However, Bash will run any
+trap set on @code{SIGINT}, as it does with any other trapped signal it
+receives while it is waiting for the foreground command to
+complete, for compatibility.
+@end enumerate
+
+@node Shell Scripts
+@section Shell Scripts
+@cindex shell script
+
+A shell script is a text file containing shell commands.  When such
+a file is used as the first non-option argument when invoking Bash,
+and neither the @option{-c} nor @option{-s} option is supplied
+(@pxref{Invoking Bash}), 
+Bash reads and executes commands from the file, then exits.  This
+mode of operation creates a non-interactive shell.  The shell first
+searches for the file in the current directory, and looks in the
+directories in @env{$PATH} if not found there.
+
+When Bash runs
+a shell script, it sets the special parameter @code{0} to the name
+of the file, rather than the name of the shell, and the positional
+parameters are set to the remaining arguments, if any are given.
+If no additional arguments are supplied, the positional parameters
+are unset.
+
+A shell script may be made executable by using the @code{chmod} command
+to turn on the execute bit.  When Bash finds such a file while
+searching the @env{$PATH} for a command, it creates a
+new instance of itself
+to execute it.
+In other words, executing
+@example
+filename @var{arguments}
+@end example
+@noindent
+is equivalent to executing
+@example
+bash filename @var{arguments}
+@end example
+
+@noindent
+if @code{filename} is an executable shell script.
+This subshell reinitializes itself, so that the effect is as if a
+new shell had been invoked to interpret the script, with the
+exception that the locations of commands remembered by the parent
+(see the description of @code{hash} in @ref{Bourne Shell Builtins})
+are retained by the child.
+
+Most versions of Unix make this a part of the operating system's command
+execution mechanism.  If the first line of a script begins with
+the two characters @samp{#!}, the remainder of the line specifies
+an interpreter for the program and, depending on the operating system, one
+or more optional arguments for that interpreter.
+Thus, you can specify Bash, @code{awk}, Perl, or some other
+interpreter and write the rest of the script file in that language.
+
+The arguments to the interpreter
+consist of one or more optional arguments following the interpreter
+name on the first line of the script file, followed by the name of
+the script file, followed by the rest of the arguments supplied to the
+script.
+The details of how the interpreter line is split into an interpreter name
+and a set of arguments vary across systems.
+Bash will perform this action on operating systems that do not handle it
+themselves.
+Note that some older versions of Unix limit the interpreter
+name and a single argument to a maximum of 32 characters, so it's not
+portable to assume that using more than one argument will work.
+
+Bash scripts often begin with @code{#! /bin/bash} (assuming that
+Bash has been installed in @file{/bin}), since this ensures that
+Bash will be used to interpret the script, even if it is executed
+under another shell. It's a common idiom to use @code{env} to find
+@code{bash} even if it's been installed in another directory:
+@code{#!/usr/bin/env bash} will find the first occurrence of @code{bash}
+in @env{$PATH}.

+
+Builtin commands are contained within the shell itself.
+When the name of a builtin command is used as the first word of
+a simple command (@pxref{Simple Commands}), the shell executes
+the command directly, without invoking another program.
+Builtin commands are necessary to implement functionality impossible
+or inconvenient to obtain with separate utilities.
+
+This section briefly describes the builtins which Bash inherits from
+the Bourne Shell, as well as the builtin commands which are unique
+to or have been extended in Bash.
+
+Several builtin commands are described in other chapters: builtin
+commands which provide the Bash interface to the job control
+facilities (@pxref{Job Control Builtins}), the directory stack
+(@pxref{Directory Stack Builtins}), the command history
+(@pxref{Bash History Builtins}), and the programmable completion
+facilities (@pxref{Programmable Completion Builtins}).
+
+Many of the builtins have been extended by @sc{posix} or Bash.
+
+Unless otherwise noted, each builtin command documented as accepting
+options preceded by @samp{-} accepts @samp{--}
+to signify the end of the options.
+The @code{:}, @code{true}, @code{false}, and @code{test}/@code{[}
+builtins do not accept options and do not treat @samp{--} specially.
+The @code{exit}, @code{logout}, @code{return},
+@code{break}, @code{continue}, @code{let},
+and @code{shift} builtins accept and process arguments beginning
+with @samp{-} without requiring @samp{--}.
+Other builtins that accept arguments but are not specified as accepting
+options interpret arguments beginning with @samp{-} as invalid options and
+require @samp{--} to prevent this interpretation.
+
+@node Bourne Shell Builtins
+@section Bourne Shell Builtins
+
+The following shell builtin commands are inherited from the Bourne Shell.
+These commands are implemented as specified by the @sc{posix} standard.
+
+@table @code
+@item :    @r{(a colon)}
+@btindex :
+@example
+: [@var{arguments}]
+@end example
+
+Do nothing beyond expanding @var{arguments} and performing redirections.
+The return status is zero.
+
+@item .    @r{(a period)}
+@btindex .
+@example
+. @var{filename} [@var{arguments}]
+@end example
+
+Read and execute commands from the @var{filename} argument in the
+current shell context.  If @var{filename} does not contain a slash,
+the @env{PATH} variable is used to find @var{filename},
+but @var{filename} does not need to be executable.
+When Bash is not in @sc{posix} mode, it searches the current directory
+if @var{filename} is not found in @env{$PATH}.
+If any @var{arguments} are supplied, they become the positional
+parameters when @var{filename} is executed.  Otherwise the positional
+parameters are unchanged.
+If the @option{-T} option is enabled, @code{.} inherits any trap on
+@code{DEBUG}; if it is not, any @code{DEBUG} trap string is saved and
+restored around the call to @code{.}, and @code{.} unsets the
+@code{DEBUG} trap while it executes.
+If @option{-T} is not set, and the sourced file changes
+the @code{DEBUG} trap, the new value is retained when @code{.} completes.
+The return status is the exit status of the last command executed, or
+zero if no commands are executed.  If @var{filename} is not found, or
+cannot be read, the return status is non-zero.
+This builtin is equivalent to @code{source}.
+
+@item break
+@btindex break
+@example
+break [@var{n}]
+@end example
+
+Exit from a @code{for}, @code{while}, @code{until}, or @code{select} loop.
+If @var{n} is supplied, the @var{n}th enclosing loop is exited.
+@var{n} must be greater than or equal to 1.
+The return status is zero unless @var{n} is not greater than or equal to 1.
+
+@item cd
+@btindex cd
+@example
+cd [-L|[-P [-e]] [-@@] [@var{directory}]
+@end example
+
+Change the current working directory to @var{directory}.
+If @var{directory} is not supplied, the value of the @env{HOME}
+shell variable is used.
+If the shell variable
+@env{CDPATH} exists, it is used as a search path:
+each directory name in @env{CDPATH} is searched for
+@var{directory}, with alternative directory names in @env{CDPATH}
+separated by a colon (@samp{:}).
+If @var{directory} begins with a slash, @env{CDPATH} is not used.
+
+The @option{-P} option means to not follow symbolic links: symbolic links
+are resolved while @code{cd} is traversing @var{directory} and before
+processing an instance of @samp{..} in @var{directory}.
+
+By default, or when the @option{-L} option is supplied, symbolic links
+in @var{directory} are resolved after @code{cd} processes an instance
+of @samp{..} in @var{directory}.
+
+If @samp{..} appears in @var{directory}, it is processed by removing the
+immediately preceding pathname component, back to a slash or the beginning
+of @var{directory}.
+
+If the @option{-e} option is supplied with @option{-P}
+and the current working directory cannot be successfully determined
+after a successful directory change, @code{cd} will return an unsuccessful
+status.
+
+On systems that support it, the @option{-@@} option presents the extended
+attributes associated with a file as a directory.              
+
+If @var{directory} is @samp{-}, it is converted to @env{$OLDPWD}
+before the directory change is attempted.
+
+If a non-empty directory name from @env{CDPATH} is used, or if
+@samp{-} is the first argument, and the directory change is
+successful, the absolute pathname of the new working directory is
+written to the standard output.
+
+If the directory change is successful, @code{cd} sets the value of the
+@env{PWD} environment variable to the new directory name, and sets the
+@env{OLDPWD} environment variable to the value of the current working
+directory before the change.
+
+The return status is zero if the directory is successfully changed,
+non-zero otherwise.
+
+@item continue
+@btindex continue
+@example
+continue [@var{n}]
+@end example
+
+Resume the next iteration of an enclosing @code{for}, @code{while},
+@code{until}, or @code{select} loop.
+If @var{n} is supplied, the execution of the @var{n}th enclosing loop
+is resumed.
+@var{n} must be greater than or equal to 1.
+The return status is zero unless @var{n} is not greater than or equal to 1.
+
+@item eval
+@btindex eval
+@example
+eval [@var{arguments}]
+@end example
+
+The arguments are concatenated together into a single command, which is
+then read and executed, and its exit status returned as the exit status
+of @code{eval}.
+If there are no arguments or only empty arguments, the return status is
+zero.
+
+@item exec
+@btindex exec
+@example
+exec [-cl] [-a @var{name}] [@var{command} [@var{arguments}]]
+@end example
+
+If @var{command}
+is supplied, it replaces the shell without creating a new process.
+If the @option{-l} option is supplied, the shell places a dash at the
+beginning of the zeroth argument passed to @var{command}.
+This is what the @code{login} program does.
+The @option{-c} option causes @var{command} to be executed with an empty
+environment.
+If @option{-a} is supplied, the shell passes @var{name} as the zeroth
+argument to @var{command}.
+If @var{command}
+cannot be executed for some reason, a non-interactive shell exits,
+unless the @code{execfail} shell option
+is enabled.  In that case, it returns failure.
+An interactive shell returns failure if the file cannot be executed.
+A subshell exits unconditionally if @code{exec} fails.
+If no @var{command} is specified, redirections may be used to affect
+the current shell environment.  If there are no redirection errors, the
+return status is zero; otherwise the return status is non-zero.
+
+@item exit
+@btindex exit
+@example
+exit [@var{n}]
+@end example
+
+Exit the shell, returning a status of @var{n} to the shell's parent.
+If @var{n} is omitted, the exit status is that of the last command executed.
+Any trap on @code{EXIT} is executed before the shell terminates.
+
+@item export
+@btindex export
+@example
+export [-fn] [-p] [@var{name}[=@var{value}]]
+@end example
+
+Mark each @var{name} to be passed to child processes
+in the environment.  If the @option{-f} option is supplied, the @var{name}s
+refer to shell functions; otherwise the names refer to shell variables.
+The @option{-n} option means to no longer mark each @var{name} for export.
+If no @var{name}s are supplied, or if the @option{-p} option is given, a
+list of names of all exported variables is displayed.
+The @option{-p} option displays output in a form that may be reused as input.
+If a variable name is followed by =@var{value}, the value of
+the variable is set to @var{value}.
+
+The return status is zero unless an invalid option is supplied, one of
+the names is not a valid shell variable name, or @option{-f} is supplied
+with a name that is not a shell function.
+
+@item getopts
+@btindex getopts
+@example
+getopts @var{optstring} @var{name} [@var{arg} @dots{}]
+@end example
+
+@code{getopts} is used by shell scripts to parse positional parameters.
+@var{optstring} contains the option characters to be recognized; if a
+character is followed by a colon, the option is expected to have an
+argument, which should be separated from it by whitespace.
+The colon (@samp{:}) and question mark (@samp{?}) may not be
+used as option characters.
+Each time it is invoked, @code{getopts}
+places the next option in the shell variable @var{name}, initializing
+@var{name} if it does not exist,
+and the index of the next argument to be processed into the
+variable @env{OPTIND}.
+@env{OPTIND} is initialized to 1 each time the shell or a shell script
+is invoked.
+When an option requires an argument,
+@code{getopts} places that argument into the variable @env{OPTARG}.
+The shell does not reset @env{OPTIND} automatically; it must be manually
+reset between multiple calls to @code{getopts} within the same shell
+invocation if a new set of parameters is to be used.
+
+When the end of options is encountered, @code{getopts} exits with a
+return value greater than zero.
+@env{OPTIND} is set to the index of the first non-option argument,
+and @var{name} is set to @samp{?}.
+
+@code{getopts}
+normally parses the positional parameters, but if more arguments are
+supplied as @var{arg} values, @code{getopts} parses those instead.
+
+@code{getopts} can report errors in two ways.  If the first character of
+@var{optstring} is a colon, @var{silent}
+error reporting is used.  In normal operation, diagnostic messages
+are printed when invalid options or missing option arguments are
+encountered.
+If the variable @env{OPTERR}
+is set to 0, no error messages will be displayed, even if the first
+character of @code{optstring} is not a colon.
+
+If an invalid option is seen,
+@code{getopts} places @samp{?} into @var{name} and, if not silent,
+prints an error message and unsets @env{OPTARG}.
+If @code{getopts} is silent, the option character found is placed in
+@env{OPTARG} and no diagnostic message is printed.
+
+If a required argument is not found, and @code{getopts}
+is not silent, a question mark (@samp{?}) is placed in @var{name},
+@code{OPTARG} is unset, and a diagnostic message is printed.
+If @code{getopts} is silent, then a colon (@samp{:}) is placed in
+@var{name} and @env{OPTARG} is set to the option character found.
+
+@item hash
+@btindex hash
+@example
+hash [-r] [-p @var{filename}] [-dt] [@var{name}]
+@end example
+
+Each time @code{hash} is invoked, it remembers the full pathnames of the
+commands specified as @var{name} arguments,
+so they need not be searched for on subsequent invocations.
+The commands are found by searching through the directories listed in
+@env{$PATH}.
+Any previously-remembered pathname is discarded.
+The @option{-p} option inhibits the path search, and @var{filename} is
+used as the location of @var{name}.
+The @option{-r} option causes the shell to forget all remembered locations.
+The @option{-d} option causes the shell to forget the remembered location
+of each @var{name}.
+If the @option{-t} option is supplied, the full pathname to which each
+@var{name} corresponds is printed.  If multiple @var{name} arguments are
+supplied with @option{-t}, the @var{name} is printed before the hashed
+full pathname.
+The @option{-l} option causes output to be displayed in a format
+that may be reused as input.
+If no arguments are given, or if only @option{-l} is supplied,
+information about remembered commands is printed.
+The return status is zero unless a @var{name} is not found or an invalid
+option is supplied.
+
+@item pwd
+@btindex pwd
+@example
+pwd [-LP]
+@end example
+
+Print the absolute pathname of the current working directory.
+If the @option{-P} option is supplied, the pathname printed will not
+contain symbolic links.
+If the @option{-L} option is supplied, the pathname printed may contain
+symbolic links.
+The return status is zero unless an error is encountered while
+determining the name of the current directory or an invalid option
+is supplied.
+
+@item readonly
+@btindex readonly
+@example
+readonly [-aAf] [-p] [@var{name}[=@var{value}]] @dots{}
+@end example
+
+Mark each @var{name} as readonly.
+The values of these names may not be changed by subsequent assignment.
+If the @option{-f} option is supplied, each @var{name} refers to a shell
+function.
+The @option{-a} option means each @var{name} refers to an indexed
+array variable; the @option{-A} option means each @var{name} refers
+to an associative array variable.
+If both options are supplied, @option{-A} takes precedence.
+If no @var{name} arguments are given, or if the @option{-p}
+option is supplied, a list of all readonly names is printed.
+The other options may be used to restrict the output to a subset of
+the set of readonly names.
+The @option{-p} option causes output to be displayed in a format that
+may be reused as input.
+If a variable name is followed by =@var{value}, the value of
+the variable is set to @var{value}.
+The return status is zero unless an invalid option is supplied, one of
+the @var{name} arguments is not a valid shell variable or function name,
+or the @option{-f} option is supplied with a name that is not a shell function.
+
+@item return
+@btindex return
+@example
+return [@var{n}]
+@end example
+
+Cause a shell function to stop executing and return the value @var{n}
+to its caller.
+If @var{n} is not supplied, the return value is the exit status of the
+last command executed in the function.
+If @code{return} is executed by a trap handler, the last command used to
+determine the status is the last command executed before the trap handler.
+If @code{return} is executed during a @code{DEBUG} trap, the last command
+used to determine the status is the last command executed by the trap
+handler before @code{return} was invoked.
+@code{return} may also be used to terminate execution of a script
+being executed with the @code{.} (@code{source}) builtin,
+returning either @var{n} or
+the exit status of the last command executed within the script as the exit
+status of the script.
+If @var{n} is supplied, the return value is its least significant
+8 bits.
+Any command associated with the @code{RETURN} trap is executed
+before execution resumes after the function or script.
+The return status is non-zero if @code{return} is supplied a non-numeric
+argument or is used outside a function
+and not during the execution of a script by @code{.} or @code{source}.
+
+@item shift
+@btindex shift
+@example
+shift [@var{n}]
+@end example
+
+Shift the positional parameters to the left by @var{n}.
+The positional parameters from @var{n}+1 @dots{} @code{$#} are
+renamed to @code{$1} @dots{} @code{$#}-@var{n}.
+Parameters represented by the numbers @code{$#} down to @code{$#}-@var{n}+1
+are unset.
+@var{n} must be a non-negative number less than or equal to @code{$#}.
+If @var{n} is zero or greater than @code{$#}, the positional parameters
+are not changed.
+If @var{n} is not supplied, it is assumed to be 1.
+The return status is zero unless @var{n} is greater than @code{$#} or
+less than zero, non-zero otherwise.
+
+@item test
+@itemx [
+@btindex test
+@btindex [
+@example
+test @var{expr}
+@end example
+
+Evaluate a conditional expression @var{expr} and return a status of 0
+(true) or 1 (false).
+Each operator and operand must be a separate argument.
+Expressions are composed of the primaries described below in
+@ref{Bash Conditional Expressions}.
+@code{test} does not accept any options, nor does it accept and ignore
+an argument of @option{--} as signifying the end of options.
+
+When the @code{[} form is used, the last argument to the command must
+be a @code{]}.
+
+Expressions may be combined using the following operators, listed in
+decreasing order of precedence.
+The evaluation depends on the number of arguments; see below.
+Operator precedence is used when there are five or more arguments.
+
+@table @code
+@item ! @var{expr}
+True if @var{expr} is false.
+
+@item ( @var{expr} )
+Returns the value of @var{expr}.
+This may be used to override the normal precedence of operators.
+
+@item @var{expr1} -a @var{expr2}
+True if both @var{expr1} and @var{expr2} are true.
+
+@item @var{expr1} -o @var{expr2}
+True if either @var{expr1} or @var{expr2} is true.
+@end table
+
+The @code{test} and @code{[} builtins evaluate conditional
+expressions using a set of rules based on the number of arguments.
+
+@table @asis
+@item 0 arguments
+The expression is false.
+
+@item 1 argument
+The expression is true if, and only if, the argument is not null.
+
+@item 2 arguments
+If the first argument is @samp{!}, the expression is true if and
+only if the second argument is null.
+If the first argument is one of the unary conditional operators
+(@pxref{Bash Conditional Expressions}), the expression
+is true if the unary test is true.
+If the first argument is not a valid unary operator, the expression is
+false.
+
+@item 3 arguments
+The following conditions are applied in the order listed.
+
+@enumerate
+@item
+If the second argument is one of the binary conditional
+operators (@pxref{Bash Conditional Expressions}), the
+result of the expression is the result of the binary test using the
+first and third arguments as operands.
+The @samp{-a} and @samp{-o} operators are considered binary operators
+when there are three arguments.
+@item
+If the first argument is @samp{!}, the value is the negation of
+the two-argument test using the second and third arguments.
+@item
+If the first argument is exactly @samp{(} and the third argument is
+exactly @samp{)}, the result is the one-argument test of the second
+argument.
+@item
+Otherwise, the expression is false.
+@end enumerate
+
+@item 4 arguments
+The following conditions are applied in the order listed.
+
+@enumerate
+@item
+If the first argument is @samp{!}, the result is the negation of
+the three-argument expression composed of the remaining arguments.
+@item
+If the first argument is exactly @samp{(} and the fourth argument is
+exactly @samp{)}, the result is the two-argument test of the second
+and third arguments.

+
+@item trap
+@btindex trap
+@example
+trap [-lp] [@var{arg}] [@var{sigspec} @dots{}]
+@end example
+
+The commands in @var{arg} are to be read and executed when the
+shell receives signal @var{sigspec}.  If @var{arg} is absent (and
+there is a single @var{sigspec}) or
+equal to @samp{-}, each specified signal's disposition is reset
+to the value it had when the shell was started.
+If @var{arg} is the null string, then the signal specified by
+each @var{sigspec} is ignored by the shell and commands it invokes.
+If @var{arg} is not present and @option{-p} has been supplied,
+the shell displays the trap commands associated with each @var{sigspec}.
+If no arguments are supplied, or
+only @option{-p} is given, @code{trap} prints the list of commands
+associated with each signal number in a form that may be reused as
+shell input.
+The @option{-l} option causes the shell to print a list of signal names
+and their corresponding numbers.
+Each @var{sigspec} is either a signal name or a signal number.
+Signal names are case insensitive and the @code{SIG} prefix is optional.
+
+If a @var{sigspec}
+is @code{0} or @code{EXIT}, @var{arg} is executed when the shell exits.
+If a @var{sigspec} is @code{DEBUG}, the command @var{arg} is executed
+before every simple command, @code{for} command, @code{case} command,
+@code{select} command, every arithmetic @code{for} command, and before
+the first command executes in a shell function.
+Refer to the description of the @code{extdebug} option to the
+@code{shopt} builtin (@pxref{The Shopt Builtin}) for details of its
+effect on the @code{DEBUG} trap.
+If a @var{sigspec} is @code{RETURN}, the command @var{arg} is executed
+each time a shell function or a script executed with the @code{.} or
+@code{source} builtins finishes executing.
+
+If a @var{sigspec} is @code{ERR}, the command @var{arg} 
+is executed whenever
+a pipeline (which may consist of a single simple
+command), a list, or a compound command returns a
+non-zero exit status,
+subject to the following conditions.
+The @code{ERR} trap is not executed if the failed command is part of the
+command list immediately following an @code{until} or @code{while} keyword,
+part of the test following the @code{if} or @code{elif} reserved words,
+part of a command executed in a @code{&&} or @code{||} list
+except the command following the final @code{&&} or @code{||},
+any command in a pipeline but the last,
+or if the command's return
+status is being inverted using @code{!}.
+These are the same conditions obeyed by the @code{errexit} (@option{-e})
+option.
+
+Signals ignored upon entry to the shell cannot be trapped or reset.
+Trapped signals that are not being ignored are reset to their original
+values in a subshell or subshell environment when one is created.
+
+The return status is zero unless a @var{sigspec} does not specify a
+valid signal.
+
+@item umask
+@btindex umask
+@example
+umask [-p] [-S] [@var{mode}]
+@end example
+
+Set the shell process's file creation mask to @var{mode}.  If
+@var{mode} begins with a digit, it is interpreted as an octal number;
+if not, it is interpreted as a symbolic mode mask similar
+to that accepted by the @code{chmod} command.  If @var{mode} is
+omitted, the current value of the mask is printed.  If the @option{-S}
+option is supplied without a @var{mode} argument, the mask is printed
+in a symbolic format.
+If the  @option{-p} option is supplied, and @var{mode}
+is omitted, the output is in a form that may be reused as input.
+The return status is zero if the mode is successfully changed or if
+no @var{mode} argument is supplied, and non-zero otherwise.
+
+Note that when the mode is interpreted as an octal number, each number
+of the umask is subtracted from @code{7}.  Thus, a umask of @code{022}
+results in permissions of @code{755}.
+
+@item unset
+@btindex unset
+@example
+unset [-fnv] [@var{name}]
+@end example
+
+Remove each variable or function @var{name}.
+If the @option{-v} option is given, each
+@var{name} refers to a shell variable and that variable is removed.
+If the @option{-f} option is given, the @var{name}s refer to shell
+functions, and the function definition is removed.
+If the @option{-n} option is supplied, and @var{name} is a variable with
+the @code{nameref} attribute, @var{name} will be unset rather than the
+variable it references.
+@option{-n} has no effect if the @option{-f} option is supplied.
+If no options are supplied, each @var{name} refers to a variable; if
+there is no variable by that name, a function with that name, if any, is
+unset.
+Readonly variables and functions may not be unset.
+Some shell variables lose their special behavior if they are unset; such
+behavior is noted in the description of the individual variables.
+The return status is zero unless a @var{name} is readonly or may not be unset.

+
+Without arguments or with the @option{-p} option, @code{alias} prints
+the list of aliases on the standard output in a form that allows
+them to be reused as input.
+If arguments are supplied, an alias is defined for each @var{name}
+whose @var{value} is given.  If no @var{value} is given, the name

+@end example
+
+Display current Readline (@pxref{Command Line Editing})
+key and function bindings,
+bind a key sequence to a Readline function or macro,
+or set a Readline variable.
+Each non-option argument is a command as it would appear in a
+Readline initialization file (@pxref{Readline Init File}),
+but each binding or command must be passed as a separate argument;  e.g.,
+@samp{"\C-x\C-r":re-read-init-file}.
+
+Options, if supplied, have the following meanings:
+
+@table @code
+@item -m @var{keymap}
+Use @var{keymap} as the keymap to be affected by
+the subsequent bindings.  Acceptable @var{keymap}
+names are
+@code{emacs},
+@code{emacs-standard},
+@code{emacs-meta},
+@code{emacs-ctlx},
+@code{vi},
+@code{vi-move},
+@code{vi-command}, and
+@code{vi-insert}.
+@code{vi} is equivalent to @code{vi-command} (@code{vi-move} is also a
+synonym); @code{emacs} is equivalent to @code{emacs-standard}.
+
+@item -l
+List the names of all Readline functions.
+
+@item -p
+Display Readline function names and bindings in such a way that they

+
+@item -u @var{function}
+Unbind all keys bound to the named @var{function}.
+
+@item -r @var{keyseq}
+Remove any current binding for @var{keyseq}.
+
+@item -x @var{keyseq:shell-command}
+Cause @var{shell-command} to be executed whenever @var{keyseq} is
+entered.
+When @var{shell-command} is executed, the shell sets the
+@code{READLINE_LINE} variable to the contents of the Readline line
+buffer and the @code{READLINE_POINT} and @code{READLINE_MARK} variables
+to the current location of the insertion point and the saved insertion
+point (the @var{mark}), respectively.
+The shell assigns any numeric argument the user supplied to the
+@code{READLINE_ARGUMENT} variable.
+If there was no argument, that variable is not set.
+If the executed command changes the value of any of @code{READLINE_LINE},
+@code{READLINE_POINT}, or @code{READLINE_MARK}, those new values will be

+
+@item builtin
+@btindex builtin
+@example
+builtin [@var{shell-builtin} [@var{args}]]
+@end example
+
+Run a shell builtin, passing it @var{args}, and return its exit status.
+This is useful when defining a shell function with the same
+name as a shell builtin, retaining the functionality of the builtin within
+the function.
+The return status is non-zero if @var{shell-builtin} is not a shell
+builtin command.
+
+@item caller
+@btindex caller
+@example
+caller [@var{expr}]
+@end example
+
+Returns the context of any active subroutine call (a shell function or
+a script executed with the @code{.} or @code{source} builtins).
+
+Without @var{expr}, @code{caller} displays the line number and source
+filename of the current subroutine call.
+If a non-negative integer is supplied as @var{expr}, @code{caller}
+displays the line number, subroutine name, and source file corresponding
+to that position in the current execution call stack.  This extra
+information may be used, for example, to print a stack trace.  The
+current frame is frame 0.
+
+The return value is 0 unless the shell is not executing a subroutine
+call or @var{expr} does not correspond to a valid position in the
+call stack.
+
+@item command
+@btindex command
+@example
+command [-pVv] @var{command} [@var{arguments} @dots{}]
+@end example
+
+Runs @var{command} with @var{arguments} ignoring any shell function
+named @var{command}.
+Only shell builtin commands or commands found by searching the
+@env{PATH} are executed.
+If there is a shell function named @code{ls}, running @samp{command ls}
+within the function will execute the external command @code{ls}
+instead of calling the function recursively.
+The @option{-p} option means to use a default value for @env{PATH}
+that is guaranteed to find all of the standard utilities.
+The return status in this case is 127 if @var{command} cannot be
+found or an error occurred, and the exit status of @var{command}
+otherwise.
+
+If either the @option{-V} or @option{-v} option is supplied, a
+description of @var{command} is printed.  The @option{-v} option
+causes a single word indicating the command or file name used to
+invoke @var{command} to be displayed; the @option{-V} option produces
+a more verbose description.  In this case, the return status is
+zero if @var{command} is found, and non-zero if not.
+
+@item declare
+@btindex declare
+@example
+declare [-aAfFgiIlnrtux] [-p] [@var{name}[=@var{value}] @dots{}]
+@end example
+
+Declare variables and give them attributes.  If no @var{name}s
+are given, then display the values of variables instead. 
+
+The @option{-p} option will display the attributes and values of each
+@var{name}.
+When @option{-p} is used with @var{name} arguments, additional options,
+other than @option{-f} and @option{-F}, are ignored.
+
+When @option{-p} is supplied without @var{name} arguments, @code{declare}
+will display the attributes and values of all variables having the
+attributes specified by the additional options.
+If no other options are supplied with @option{-p}, @code{declare} will
+display the attributes and values of all shell variables.  The @option{-f}
+option will restrict the display to shell functions.
+
+The @option{-F} option inhibits the display of function definitions;
+only the function name and attributes are printed.
+If the @code{extdebug} shell option is enabled using @code{shopt}
+(@pxref{The Shopt Builtin}), the source file name and line number where
+each @var{name} is defined are displayed as well.
+@option{-F} implies @option{-f}.
+
+The @option{-g} option forces variables to be created or modified at
+the global scope, even when @code{declare} is executed in a shell function.
+It is ignored in all other cases.
+
+The @option{-I} option causes local variables to inherit the attributes
+(except the @code{nameref} attribute)
+and value of any existing variable with the same
+@var{name} at a surrounding scope.
+If there is no existing variable, the local variable is initially unset.
+
+The following options can be used to restrict output to variables with
+the specified attributes or to give variables attributes:
+
+@table @code
+@item -a
+Each @var{name} is an indexed array variable (@pxref{Arrays}).
+
+@item -A
+Each @var{name} is an associative array variable (@pxref{Arrays}).
+
+@item -f
+Use function names only.
+
+@item -i
+The variable is to be treated as
+an integer; arithmetic evaluation (@pxref{Shell Arithmetic}) is
+performed when the variable is assigned a value.
+
+@item -l
+When the variable is assigned a value, all upper-case characters are
+converted to lower-case.
+The upper-case attribute is disabled.
+
+@item -n
+Give each @var{name} the @code{nameref} attribute, making
+it a name reference to another variable.
+That other variable is defined by the value of @var{name}.
+All references, assignments, and attribute modifications
+to @var{name}, except for those using or changing the
+@option{-n} attribute itself, are performed on the variable referenced by
+@var{name}'s value.
+The nameref attribute cannot be applied to array variables.
+
+@item -r
+Make @var{name}s readonly.  These names cannot then be assigned values
+by subsequent assignment statements or unset.
+
+@item -t
+Give each @var{name} the @code{trace} attribute.
+Traced functions inherit the @code{DEBUG} and @code{RETURN} traps from
+the calling shell.
+The trace attribute has no special meaning for variables.
+
+@item -u
+When the variable is assigned a value, all lower-case characters are
+converted to upper-case.
+The lower-case attribute is disabled.
+
+@item -x
+Mark each @var{name} for export to subsequent commands via
+the environment.
+@end table
+
+Using @samp{+} instead of @samp{-} turns off the attribute instead,
+with the exceptions that @samp{+a} and @samp{+A}
+may not be used to destroy array variables and @samp{+r} will not
+remove the readonly attribute.
+When used in a function, @code{declare} makes each @var{name} local,
+as with the @code{local} command, unless the @option{-g} option is used.
+If a variable name is followed by =@var{value}, the value of the variable
+is set to @var{value}.
+
+When using @option{-a} or @option{-A} and the compound assignment syntax to 
+create array variables, additional attributes do not take effect until
+subsequent assignments.
+
+The return status is zero unless an invalid option is encountered,
+an attempt is made to define a function using @samp{-f foo=bar},
+an attempt is made to assign a value to a readonly variable,
+an attempt is made to assign a value to an array variable without
+using the compound assignment syntax (@pxref{Arrays}),
+one of the @var{name}s is not a valid shell variable name,
+an attempt is made to turn off readonly status for a readonly variable,
+an attempt is made to turn off array status for an array variable,
+or an attempt is made to display a non-existent function with @option{-f}.
+
+@item echo
+@btindex echo
+@example
+echo [-neE] [@var{arg} @dots{}]
+@end example
+
+Output the @var{arg}s, separated by spaces, terminated with a
+newline.
+The return status is 0 unless a write error occurs.
+If @option{-n} is specified, the trailing newline is suppressed.
+If the @option{-e} option is given, interpretation of the following
+backslash-escaped characters is enabled.
+The @option{-E} option disables the interpretation of these escape characters,
+even on systems where they are interpreted by default.
+The @code{xpg_echo} shell option may be used to
+dynamically determine whether or not @code{echo} expands these
+escape characters by default.
+@code{echo} does not interpret @option{--} to mean the end of options.
+
+@code{echo} interprets the following escape sequences:
+@table @code

+(zero to three octal digits)
+@item \x@var{HH}
+the eight-bit character whose value is the hexadecimal value @var{HH}
+(one or two hex digits)
+@item \u@var{HHHH}
+the Unicode (ISO/IEC 10646) character whose value is the hexadecimal value
+@var{HHHH} (one to four hex digits)
+@item \U@var{HHHHHHHH}
+the Unicode (ISO/IEC 10646) character whose value is the hexadecimal value

+@end table
+
+@item enable
+@btindex enable
+@example
+enable [-a] [-dnps] [-f @var{filename}] [@var{name} @dots{}]
+@end example
+
+Enable and disable builtin shell commands.
+Disabling a builtin allows a disk command which has the same name
+as a shell builtin to be executed without specifying a full pathname,
+even though the shell normally searches for builtins before disk commands.
+If @option{-n} is used, the @var{name}s become disabled.  Otherwise
+@var{name}s are enabled.  For example, to use the @code{test} binary
+found via @env{$PATH} instead of the shell builtin version, type
+@samp{enable -n test}.
+
+If the @option{-p} option is supplied, or no @var{name} arguments appear,
+a list of shell builtins is printed.  With no other arguments, the list
+consists of all enabled shell builtins.
+The @option{-a} option means to list
+each builtin with an indication of whether or not it is enabled. 
+
+The @option{-f} option means to load the new builtin command @var{name}
+from shared object @var{filename}, on systems that support dynamic loading.
+Bash will use the value of the @env{BASH_LOADABLES_PATH} variable as a
+colon-separated list of directories in which to search for @var{filename}.
+The default is system-dependent.
+The @option{-d} option will delete a builtin loaded with @option{-f}.
+
+If there are no options, a list of the shell builtins is displayed.
+The @option{-s} option restricts @code{enable} to the @sc{posix} special
+builtins.  If @option{-s} is used with @option{-f}, the new builtin becomes
+a special builtin (@pxref{Special Builtins}).
+
+If no options are supplied and a @var{name} is not a shell builtin,
+@code{enable} will attempt to load @var{name} from a shared object named
+@var{name}, as if the command were
+@samp{enable -f @var{name} @var{name}}.
+
+The return status is zero unless a @var{name} is not a shell builtin
+or there is an error loading a new builtin from a shared object.
+
+@item help
+@btindex help
+@example
+help [-dms] [@var{pattern}]
+@end example
+
+Display helpful information about builtin commands.
+If @var{pattern} is specified, @code{help} gives detailed help
+on all commands matching @var{pattern}, otherwise a list of
+the builtins is printed.
+
+Options, if supplied, have the following meanings:
+
+@table @code
+@item -d
+Display a short description of each @var{pattern}
+@item -m
+Display the description of each @var{pattern} in a manpage-like format
+@item -s
+Display only a short usage synopsis for each @var{pattern}
+@end table
+
+The return status is zero unless no command matches @var{pattern}.
+
+@item let
+@btindex let
+@example
+let @var{expression} [@var{expression} @dots{}]
+@end example
+
+The @code{let} builtin allows arithmetic to be performed on shell
+variables.  Each @var{expression} is evaluated according to the
+rules given below in @ref{Shell Arithmetic}.  If the
+last @var{expression} evaluates to 0, @code{let} returns 1;
+otherwise 0 is returned.
+
+@item local
+@btindex local
+@example
+local [@var{option}] @var{name}[=@var{value}] @dots{}
+@end example
+
+For each argument, a local variable named @var{name} is created,
+and assigned @var{value}.
+The @var{option} can be any of the options accepted by @code{declare}.
+@code{local} can only be used within a function; it makes the variable
+@var{name} have a visible scope restricted to that function and its
+children.
+If @var{name} is @samp{-}, the set of shell options is made local to the
+function in which @code{local} is invoked: shell options changed using
+the @code{set} builtin inside the function are restored to their original
+values when the function returns.
+The restore is effected as if a series of @code{set} commands were executed
+to restore the values that were in place before the function.
+The return status is zero unless @code{local} is used outside
+a function, an invalid @var{name} is supplied, or @var{name} is a
+readonly variable.
+
+@item logout
+@btindex logout
+@example
+logout [@var{n}]
+@end example
+
+Exit a login shell, returning a status of @var{n} to the shell's
+parent.
+
+@item mapfile
+@btindex mapfile
+@example
+mapfile [-d @var{delim}] [-n @var{count}] [-O @var{origin}] [-s @var{count}]
+    [-t] [-u @var{fd}] [-C @var{callback}] [-c @var{quantum}] [@var{array}]
+@end example
+
+Read lines from the standard input into the indexed array variable @var{array},
+or from file descriptor @var{fd}
+if the @option{-u} option is supplied.
+The variable @code{MAPFILE} is the default @var{array}.
+Options, if supplied, have the following meanings:
+
+@table @code
+
+@item -d
+The first character of @var{delim} is used to terminate each input line,
+rather than newline.
+If @var{delim} is the empty string, @code{mapfile} will terminate a line
+when it reads a NUL character.
+@item -n
+Copy at most @var{count} lines.  If @var{count} is 0, all lines are copied.
+@item -O
+Begin assigning to @var{array} at index @var{origin}.
+The default index is 0.
+@item -s
+Discard the first @var{count} lines read.
+@item -t
+Remove a trailing @var{delim} (default newline) from each line read.
+@item -u
+Read lines from file descriptor @var{fd} instead of the standard input.
+@item -C
+Evaluate @var{callback} each time @var{quantum} lines are read.
+The @option{-c} option specifies @var{quantum}.
+@item -c
+Specify the number of lines read between each call to @var{callback}.
+@end table
+
+If @option{-C} is specified without @option{-c},
+the default quantum is 5000.
+When @var{callback}  is evaluated, it is supplied the index of the next
+array element to be assigned and the line to be assigned to that element
+as additional arguments.
+@var{callback} is evaluated after the line is read but before the
+array element is assigned.
+
+If not supplied with an explicit origin, @code{mapfile} will clear @var{array}
+before assigning to it.
+
+@code{mapfile} returns successfully unless an invalid option or option
+argument is supplied, @var{array} is invalid or unassignable, or @var{array}
+is not an indexed array.
+
+@item printf
+@btindex printf
+@example
+printf [-v @var{var}] @var{format} [@var{arguments}]
+@end example
+
+Write the formatted @var{arguments} to the standard output under the
+control of the @var{format}.
+The @option{-v} option causes the output to be assigned to the variable
+@var{var} rather than being printed to the standard output.
+
+The @var{format} is a character string which contains three types of objects:
+plain characters, which are simply copied to standard output, character
+escape sequences, which are converted and copied to the standard output, and
+format specifications, each of which causes printing of the next successive
+@var{argument}.
+In addition to the standard @code{printf(1)} formats, @code{printf}
+interprets the following extensions:
+
+@table @code
+@item %b
+Causes @code{printf} to expand backslash escape sequences in the
+corresponding @var{argument} in the same way as @code{echo -e}
+(@pxref{Bash Builtins}).
+@item %q
+Causes @code{printf} to output the
+corresponding @var{argument} in a format that can be reused as shell input.
+@item %Q
+like @code{%q}, but applies any supplied precision to the @var{argument}
+before quoting it.
+@item %(@var{datefmt})T
+Causes @code{printf} to output the date-time string resulting from using
+@var{datefmt} as a format string for @code{strftime}(3).
+The corresponding @var{argument} is an integer representing the number of
+seconds since the epoch.
+Two special argument values may be used: -1 represents the current
+time, and -2 represents the time the shell was invoked.
+If no argument is specified, conversion behaves as if -1 had been given.
+This is an exception to the usual @code{printf} behavior.
+@end table
+
+@noindent
+The %b, %q, and %T directives all use the field width and precision
+arguments from the format specification and write that many bytes from    
+(or use that wide a field for) the expanded argument, which usually
+contains more characters than the original.
+
+Arguments to non-string format specifiers are treated as C language constants,
+except that a leading plus or minus sign is allowed, and if the leading
+character is a single or double quote, the value is the ASCII value of
+the following character.
+
+The @var{format} is reused as necessary to consume all of the @var{arguments}.
+If the @var{format} requires more @var{arguments} than are supplied, the
+extra format specifications behave as if a zero value or null string, as
+appropriate, had been supplied.  The return value is zero on success,
+non-zero on failure.
+
+@item read
+@btindex read
+@example
+read [-ers] [-a @var{aname}] [-d @var{delim}] [-i @var{text}] [-n @var{nchars}]
+    [-N @var{nchars}] [-p @var{prompt}] [-t @var{timeout}] [-u @var{fd}] [@var{name} @dots{}]
+@end example
+
+One line is read from the standard input, or from the file descriptor
+@var{fd} supplied as an argument to the @option{-u} option,
+split into words as described above in @ref{Word Splitting},
+and the first word
+is assigned to the first @var{name}, the second word to the second @var{name},
+and so on.
+If there are more words than names,
+the remaining words and their intervening delimiters are assigned
+to the last @var{name}.
+If there are fewer words read from the input stream than names,
+the remaining names are assigned empty values.
+The characters in the value of the @env{IFS} variable
+are used to split the line into words using the same rules the shell
+uses for expansion (described above in @ref{Word Splitting}).
+The backslash character @samp{\} may be used to remove any special
+meaning for the next character read and for line continuation.
+
+Options, if supplied, have the following meanings:
+
+@table @code
+@item -a @var{aname}
+The words are assigned to sequential indices of the array variable
+@var{aname}, starting at 0.
+All elements are removed from @var{aname} before the assignment.
+Other @var{name} arguments are ignored.
+
+@item -d @var{delim}
+The first character of @var{delim} is used to terminate the input line,
+rather than newline.
+If @var{delim} is the empty string, @code{read} will terminate a line
+when it reads a NUL character.
+
+@item -e
+Readline (@pxref{Command Line Editing}) is used to obtain the line.
+Readline uses the current (or default, if line editing was not previously
+active) editing settings, but uses Readline's default filename completion.
+
+@item -i @var{text}
+If Readline is being used to read the line, @var{text} is placed into
+the editing buffer before editing begins.
+
+@item -n @var{nchars}
+@code{read} returns after reading @var{nchars} characters rather than
+waiting for a complete line of input, but honors a delimiter if fewer
+than @var{nchars} characters are read before the delimiter.
+
+@item -N @var{nchars}
+@code{read} returns after reading exactly @var{nchars} characters rather
+than waiting for a complete line of input, unless EOF is encountered or
+@code{read} times out.
+Delimiter characters encountered in the input are
+not treated specially and do not cause @code{read} to return until
+@var{nchars} characters are read.
+The result is not split on the characters in @code{IFS}; the intent is
+that the variable is assigned exactly the characters read
+(with the exception of backslash; see the @option{-r} option below).
+
+@item -p @var{prompt}
+Display @var{prompt}, without a trailing newline, before attempting
+to read any input.
+The prompt is displayed only if input is coming from a terminal.
+
+@item -r
+If this option is given, backslash does not act as an escape character.
+The backslash is considered to be part of the line.
+In particular, a backslash-newline pair may not then be used as a line
+continuation.
+
+@item -s
+Silent mode.  If input is coming from a terminal, characters are
+not echoed.
+
+@item -t @var{timeout}
+Cause @code{read} to time out and return failure if a complete line of
+input (or a specified number of characters)
+is not read within @var{timeout} seconds.
+@var{timeout}  may be a decimal number with a fractional portion following
+the decimal point.
+This option is only effective if @code{read} is reading input from a
+terminal, pipe, or other special file; it has no effect when reading
+from regular files.
+If @code{read} times out, @code{read} saves any partial input read into
+the specified variable @var{name}.
+If @var{timeout} is 0, @code{read} returns immediately, without trying to
+read any data.
+The exit status is 0 if input is available on the specified file descriptor,
+or the read will return EOF,
+non-zero otherwise.
+The exit status is greater than 128 if the timeout is exceeded.
+
+@item -u @var{fd}
+Read input from file descriptor @var{fd}.
+@end table
+
+If no @var{name}s are supplied, the line read,
+without the ending delimiter but otherwise unmodified,
+is assigned to the
+variable @env{REPLY}.
+The exit status is zero, unless end-of-file is encountered, @code{read}
+times out (in which case the status is greater than 128),
+a variable assignment error (such as assigning to a readonly variable) occurs,
+or an invalid file descriptor is supplied as the argument to @option{-u}.
+
+@item readarray
+@btindex readarray
+@example
+readarray [-d @var{delim}] [-n @var{count}] [-O @var{origin}] [-s @var{count}]
+    [-t] [-u @var{fd}] [-C @var{callback}] [-c @var{quantum}] [@var{array}]
+@end example
+
+Read lines from the standard input into the indexed array variable @var{array},
+or from file descriptor @var{fd}
+if the @option{-u} option is supplied.
+
+A synonym for @code{mapfile}.
+
+@item source
+@btindex source
+@example
+source @var{filename}
+@end example
+
+A synonym for @code{.} (@pxref{Bourne Shell Builtins}).
+
+@item type
+@btindex type
+@example
+type [-afptP] [@var{name} @dots{}]
+@end example
+
+For each @var{name}, indicate how it would be interpreted if used as a
+command name.
+
+If the @option{-t} option is used, @code{type} prints a single word
+which is one of @samp{alias}, @samp{function}, @samp{builtin},
+@samp{file} or @samp{keyword},
+if @var{name} is an alias, shell function, shell builtin,
+disk file, or shell reserved word, respectively.
+If the @var{name} is not found, then nothing is printed, and
+@code{type} returns a failure status.
+
+If the @option{-p} option is used, @code{type} either returns the name
+of the disk file that would be executed, or nothing if @option{-t}
+would not return @samp{file}.
+
+The @option{-P} option forces a path search for each @var{name}, even if
+@option{-t} would not return @samp{file}.
+
+If a command is hashed, @option{-p} and @option{-P} print the hashed value,
+which is not necessarily the file that appears first in @code{$PATH}.
+
+If the @option{-a} option is used, @code{type} returns all of the places
+that contain an executable named @var{file}.
+This includes aliases and functions, if and only if the @option{-p} option
+is not also used.
+
+If the @option{-f} option is used, @code{type} does not attempt to find
+shell functions, as with the @code{command} builtin.
+
+The return status is zero if all of the @var{name}s are found, non-zero
+if any are not found.
+
+@item typeset
+@btindex typeset
+@example
+typeset [-afFgrxilnrtux] [-p] [@var{name}[=@var{value}] @dots{}]
+@end example
+
+The @code{typeset} command is supplied for compatibility with the Korn
+shell.
+It is a synonym for the @code{declare} builtin command.
+
+@item ulimit
+@btindex ulimit
+@example
+ulimit [-HS] -a
+ulimit [-HS] [-bcdefiklmnpqrstuvxPRT] [@var{limit}]
+@end example
+
+@code{ulimit} provides control over the resources available to processes
+started by the shell, on systems that allow such control.  If an
+option is given, it is interpreted as follows:
+
+@table @code
+@item -S
+Change and report the soft limit associated with a resource.
+
+@item -H
+Change and report the hard limit associated with a resource.
+
+@item -a
+All current limits are reported; no limits are set.
+
+@item -b
+The maximum socket buffer size.
+
+@item -c
+The maximum size of core files created.
+
+@item -d
+The maximum size of a process's data segment.
+
+@item -e
+The maximum scheduling priority ("nice").
+
+@item -f
+The maximum size of files written by the shell and its children.
+
+@item -i
+The maximum number of pending signals.
+
+@item -k
+The maximum number of kqueues that may be allocated.
+
+@item -l
+The maximum size that may be locked into memory.
+
+@item -m
+The maximum resident set size (many systems do not honor this limit).
+
+@item -n
+The maximum number of open file descriptors (most systems do not
+allow this value to be set).
+
+@item -p
+The pipe buffer size.
+
+@item -q
+The maximum number of bytes in @sc{posix} message queues.
+
+@item -r
+The maximum real-time scheduling priority.
+
+@item -s
+The maximum stack size.
+
+@item -t
+The maximum amount of cpu time in seconds.
+
+@item -u
+The maximum number of processes available to a single user.
+
+@item -v
+The maximum amount of virtual memory available to the shell, and, on
+some systems, to its children.
+
+@item -x
+The maximum number of file locks.
+
+@item -P
+The maximum number of pseudoterminals.
+
+@item -R
+The maximum time a real-time process can run before blocking, in microseconds.
+
+@item -T
+The maximum number of threads.
+@end table
+
+If @var{limit} is given, and the @option{-a} option is not used,
+@var{limit} is the new value of the specified resource.
+The special @var{limit} values @code{hard}, @code{soft}, and
+@code{unlimited} stand for the current hard limit, the current soft limit,
+and no limit, respectively.
+A hard limit cannot be increased by a non-root user once it is set;
+a soft limit may be increased up to the value of the hard limit.
+Otherwise, the current value of the soft limit for the specified resource
+is printed, unless the @option{-H} option is supplied.
+When more than one
+resource is specified, the limit name and unit, if appropriate,
+are printed before the value.
+When setting new limits, if neither @option{-H} nor @option{-S} is supplied,
+both the hard and soft limits are set.
+If no option is given, then @option{-f} is assumed.  Values are in 1024-byte
+increments, except for
+@option{-t}, which is in seconds;
+@option{-R}, which is in microseconds;
+@option{-p}, which is in units of 512-byte blocks;
+@option{-P},
+@option{-T},
+@option{-b},
+@option{-k},
+@option{-n} and @option{-u}, which are unscaled values;
+and, when in @sc{posix} Mode (@pxref{Bash POSIX Mode}),
+@option{-c} and @option{-f}, which are in 512-byte increments.
+
+The return status is zero unless an invalid option or argument is supplied,
+or an error occurs while setting a new limit.
+
+@item unalias
+@btindex unalias
+@example
+unalias [-a] [@var{name} @dots{} ]
+@end example
+
+Remove each @var{name} from the list of aliases.  If @option{-a} is
+supplied, all aliases are removed.
+Aliases are described in @ref{Aliases}.

+@node The Set Builtin
+@subsection The Set Builtin
+
+This builtin is so complicated that it deserves its own section.  @code{set}
+allows you to change the values of shell options and set the positional
+parameters, or to display the names and values of shell variables.
+
+@table @code
+@item set
+@btindex set
+@example
+set [-abefhkmnptuvxBCEHPT] [-o @var{option-name}] [--] [-] [@var{argument} @dots{}]
+set [+abefhkmnptuvxBCEHPT] [+o @var{option-name}] [--] [-] [@var{argument} @dots{}]
+@end example
+
+If no options or arguments are supplied, @code{set} displays the names
+and values of all shell variables and functions, sorted according to the
+current locale, in a format that may be reused as input
+for setting or resetting the currently-set variables.
+Read-only variables cannot be reset.
+In @sc{posix} mode, only shell variables are listed.
+
+When options are supplied, they set or unset shell attributes.
+Options, if specified, have the following meanings:
+
+@table @code
+@item -a
+Each variable or function that is created or modified is given the
+export attribute and marked for export to the environment of
+subsequent commands.
+
+@item -b
+Cause the status of terminated background jobs to be reported
+immediately, rather than before printing the next primary prompt.
+
+@item -e
+Exit immediately if
+a pipeline (@pxref{Pipelines}), which may consist of a single simple command
+(@pxref{Simple Commands}),
+a list (@pxref{Lists}),
+or a compound command (@pxref{Compound Commands})
+returns a non-zero status.
+The shell does not exit if the command that fails is part of the
+command list immediately following a @code{while} or @code{until} keyword,
+part of the test in an @code{if} statement,
+part of any command executed in a @code{&&} or @code{||} list except
+the command following the final @code{&&} or @code{||},
+any command in a pipeline but the last,
+or if the command's return status is being inverted with @code{!}.
+If a compound command other than a subshell
+returns a non-zero status because a command failed
+while @option{-e} was being ignored, the shell does not exit.
+A trap on @code{ERR}, if set, is executed before the shell exits.
+
+This option applies to the shell environment and each subshell environment
+separately (@pxref{Command Execution Environment}), and may cause
+subshells to exit before executing all the commands in the subshell.
+
+If a compound command or shell function executes in a context where
+@option{-e} is being ignored,
+none of the commands executed within the compound command or function body
+will be affected by the @option{-e} setting, even if @option{-e} is set
+and a command returns a failure status.
+If a compound command or shell function sets @option{-e} while executing in
+a context where @option{-e} is ignored, that setting will not have any
+effect until the compound command or the command containing the function
+call completes.
+
+@item -f
+Disable filename expansion (globbing).
+
+@item -h
+Locate and remember (hash) commands as they are looked up for execution.
+This option is enabled by default.
+
+@item -k
+All arguments in the form of assignment statements are placed
+in the environment for a command, not just those that precede
+the command name.
+
+@item -m
+Job control is enabled (@pxref{Job Control}).
+All processes run in a separate process group.
+When a background job completes, the shell prints a line
+containing its exit status.
+
+@item -n
+Read commands but do not execute them.
+This may be used to check a script for syntax errors.
+This option is ignored by interactive shells.
+
+@item -o @var{option-name}
+
+Set the option corresponding to @var{option-name}:
+
+@table @code
+@item allexport
+Same as @code{-a}.
+
+@item braceexpand
+Same as @code{-B}.
+
+@item emacs
+Use an @code{emacs}-style line editing interface (@pxref{Command Line Editing}).
+This also affects the editing interface used for @code{read -e}.

+An interactive shell will not exit upon reading EOF.
+
+@item keyword
+Same as @code{-k}.

+
+@item onecmd
+Same as @code{-t}.
+
+@item physical
+Same as @code{-P}.
+
+@item pipefail
+If set, the return value of a pipeline is the value of the last
+(rightmost) command to exit with a non-zero status, or zero if all
+commands in the pipeline exit successfully.
+This option is disabled by default.
+
+@item posix
+Change the behavior of Bash where the default operation differs
+from the @sc{posix} standard to match the standard
+(@pxref{Bash POSIX Mode}).
+This is intended to make Bash behave as a strict superset of that
+standard.
+
+@item privileged
+Same as @code{-p}.
+
+@item verbose
+Same as @code{-v}.
+
+@item vi
+Use a @code{vi}-style line editing interface.
+This also affects the editing interface used for @code{read -e}.
+
+@item xtrace
+Same as @code{-x}.
+@end table
+
+@item -p
+Turn on privileged mode.
+In this mode, the @env{$BASH_ENV} and @env{$ENV} files are not
+processed, shell functions are not inherited from the environment,
+and the @env{SHELLOPTS}, @env{BASHOPTS}, @env{CDPATH} and @env{GLOBIGNORE}
+variables, if they appear in the environment, are ignored.
+If the shell is started with the effective user (group) id not equal to the
+real user (group) id, and the @option{-p} option is not supplied, these actions
+are taken and the effective user id is set to the real user id.
+If the @option{-p} option is supplied at startup, the effective user id is
+not reset.
+Turning this option off causes the effective user
+and group ids to be set to the real user and group ids.
+
+@item -r
+Enable restricted shell mode.
+This option cannot be unset once it has been set.
+
+@item -t
+Exit after reading and executing one command.
+
+@item -u
+Treat unset variables and parameters other than the special parameters
+@samp{@@} or @samp{*},
+or array variables subscripted with @samp{@@} or @samp{*},
+as an error when performing parameter expansion.
+An error message will be written to the standard error, and a non-interactive
+shell will exit.
+
+@item -v
+Print shell input lines as they are read.
+
+@item -x
+Print a trace of simple commands, @code{for} commands, @code{case}
+commands, @code{select} commands, and arithmetic @code{for} commands
+and their arguments or associated word lists after they are
+expanded and before they are executed.  The value of the @env{PS4}
+variable is expanded and the resultant value is printed before
+the command and its expanded arguments.
+
+@item -B
+The shell will perform brace expansion (@pxref{Brace Expansion}).
+This option is on by default.
+
+@item -C
+Prevent output redirection using @samp{>}, @samp{>&}, and @samp{<>}
+from overwriting existing files.
+
+@item -E
+If set, any trap on @code{ERR} is inherited by shell functions, command
+substitutions, and commands executed in a subshell environment.
+The @code{ERR} trap is normally not inherited in such cases.
+
+@item -H
+Enable @samp{!} style history substitution (@pxref{History Interaction}).
+This option is on by default for interactive shells.
+
+@item -P
+If set, do not resolve symbolic links when performing commands such as
+@code{cd} which change the current directory.  The physical directory
+is used instead.  By default, Bash follows
+the logical chain of directories when performing commands
+which change the current directory.
+
+For example, if @file{/usr/sys} is a symbolic link to @file{/usr/local/sys}
+then:
+@example
+$ cd /usr/sys; echo $PWD
+/usr/sys
+$ cd ..; pwd
+/usr
+@end example
+
+@noindent
+If @code{set -P} is on, then:
+@example
+$ cd /usr/sys; echo $PWD
+/usr/local/sys
+$ cd ..; pwd
+/usr/local
+@end example
+
+@item -T
+If set, any trap on @code{DEBUG} and @code{RETURN} are inherited by
+shell functions, command substitutions, and commands executed
+in a subshell environment.
+The @code{DEBUG} and @code{RETURN} traps are normally not inherited
+in such cases.
+
+@item --
+If no arguments follow this option, then the positional parameters are
+unset.  Otherwise, the positional parameters are set to the
+@var{arguments}, even if some of them begin with a @samp{-}.
+
+@item -
+Signal the end of options, cause all remaining @var{arguments}
+to be assigned to the positional parameters.  The @option{-x}
+and @option{-v}  options are turned off.
+If there are no arguments, the positional parameters remain unchanged.
+@end table
+
+Using @samp{+} rather than @samp{-} causes these options to be
+turned off.  The options can also be used upon invocation of the
+shell.  The current set of options may be found in @code{$-}.
+
+The remaining N @var{arguments} are positional parameters and are
+assigned, in order, to @code{$1}, @code{$2}, @dots{}  @code{$N}.
+The special parameter @code{#} is set to N.
+
+The return status is always zero unless an invalid option is supplied.

+The settings can be either those listed below, or, if the
+@option{-o} option is used, those available with the @option{-o}
+option to the @code{set} builtin command (@pxref{The Set Builtin}).
+With no options, or with the @option{-p} option, a list of all settable
+options is displayed, with an indication of whether or not each is set;
+if @var{optname}s are supplied, the output is restricted to those options.
+The @option{-p} option causes output to be displayed in a form that
+may be reused as input.
+Other options have the following meanings:
+
+@table @code
+@item -s
+Enable (set) each @var{optname}.
+
+@item -u
+Disable (unset) each @var{optname}.
+
+@item -q
+Suppresses normal output; the return status
+indicates whether the @var{optname} is set or unset.
+If multiple @var{optname} arguments are given with @option{-q},
+the return status is zero if all @var{optname}s are enabled;
+non-zero otherwise.
+
+@item -o
+Restricts the values of
+@var{optname} to be those defined for the @option{-o} option to the
+@code{set} builtin (@pxref{The Set Builtin}).
+@end table
+
+If either @option{-s} or @option{-u}
+is used with no @var{optname} arguments, @code{shopt} shows only
+those options which are set or unset, respectively.
+
+Unless otherwise noted, the @code{shopt} options are disabled (off)
+by default.
+
+The return status when listing options is zero if all @var{optname}s
+are enabled, non-zero otherwise.  When setting or unsetting options,
+the return status is zero unless an @var{optname} is not a valid shell
+option.
+
+The list of @code{shopt} options is:
+@table @code
+
+@item assoc_expand_once
+If set, the shell suppresses multiple evaluation of associative array
+subscripts during arithmetic expression evaluation, while executing
+builtins that can perform variable assignments,
+and while executing builtins that perform array dereferencing.
+
+@item autocd
+If set, a command name that is the name of a directory is executed as if
+it were the argument to the @code{cd} command.
+This option is only used by interactive shells.
+
+@item cdable_vars
+If this is set, an argument to the @code{cd} builtin command that
+is not a directory is assumed to be the name of a variable whose
+value is the directory to change to.
+
+@item cdspell
+If set, minor errors in the spelling of a directory component in a
+@code{cd} command will be corrected.
+The errors checked for are transposed characters,
+a missing character, and a character too many.
+If a correction is found, the corrected path is printed,
+and the command proceeds.
+This option is only used by interactive shells.
+
+@item checkhash
+If this is set, Bash checks that a command found in the hash
+table exists before trying to execute it.  If a hashed command no
+longer exists, a normal path search is performed.
+
+@item checkjobs
+If set, Bash lists the status of any stopped and running jobs before
+exiting an interactive shell.  If any jobs are running, this causes
+the exit to be deferred until a second exit is attempted without an
+intervening command (@pxref{Job Control}).
+The shell always postpones exiting if any jobs are stopped.
+
+@item checkwinsize
+If set, Bash checks the window size after each external (non-builtin)
+command and, if necessary, updates the values of    
+@env{LINES} and @env{COLUMNS}.
+This option is enabled by default.
+
+@item cmdhist
+If set, Bash
+attempts to save all lines of a multiple-line
+command in the same history entry.  This allows
+easy re-editing of multi-line commands.
+This option is enabled by default, but only has an effect if command
+history is enabled (@pxref{Bash History Facilities}).
+
+@item compat31
+@itemx compat32
+@itemx compat40
+@itemx compat41
+@itemx compat42
+@itemx compat43
+@itemx compat44
+These control aspects of the shell's compatibility mode
+(@pxref{Shell Compatibility Mode}).
+
+@item complete_fullquote
+If set, Bash
+quotes all shell metacharacters in filenames and directory names when
+performing completion.
+If not set, Bash
+removes metacharacters such as the dollar sign from the set of
+characters that will be quoted in completed filenames
+when these metacharacters appear in shell variable references in words to be
+completed.
+This means that dollar signs in variable names that expand to directories
+will not be quoted;
+however, any dollar signs appearing in filenames will not be quoted, either.
+This is active only when bash is using backslashes to quote completed
+filenames.
+This variable is set by default, which is the default Bash behavior in
+versions through 4.2.
+
+@item direxpand
+If set, Bash
+replaces directory names with the results of word expansion when performing
+filename completion.  This changes the contents of the Readline editing
+buffer.
+If not set, Bash attempts to preserve what the user typed.
+
+@item dirspell
+If set, Bash
+attempts spelling correction on directory names during word completion 
+if the directory name initially supplied does not exist.
+
+@item dotglob
+If set, Bash includes filenames beginning with a `.' in
+the results of filename expansion.
+The filenames @samp{.} and @samp{..} must always be matched explicitly,
+even if @code{dotglob} is set.
+
+@item execfail
+If this is set, a non-interactive shell will not exit if
+it cannot execute the file specified as an argument to the @code{exec}
+builtin command.  An interactive shell does not exit if @code{exec}
+fails.
+
+@item expand_aliases
+If set, aliases are expanded as described below under Aliases,
+@ref{Aliases}.
+This option is enabled by default for interactive shells.
+
+@item extdebug
+If set at shell invocation,
+or in a shell startup file,
+arrange to execute the debugger profile
+before the shell starts, identical to the @option{--debugger} option.
+If set after invocation, behavior intended for use by debuggers is enabled:
+
+@enumerate
+@item
+The @option{-F} option to the @code{declare} builtin (@pxref{Bash Builtins})
+displays the source file name and line number corresponding to each function
+name supplied as an argument.
+
+@item
+If the command run by the @code{DEBUG} trap returns a non-zero value, the
+next command is skipped and not executed.
+
+@item
+If the command run by the @code{DEBUG} trap returns a value of 2, and the
+shell is executing in a subroutine (a shell function or a shell script
+executed by the @code{.} or @code{source} builtins), the shell simulates
+a call to @code{return}.
+
+@item
+@code{BASH_ARGC} and @code{BASH_ARGV} are updated as described in their
+descriptions (@pxref{Bash Variables}).
+
+@item
+Function tracing is enabled: command substitution, shell functions, and
+subshells invoked with @code{( @var{command} )} inherit the
+@code{DEBUG} and @code{RETURN} traps.
+
+@item
+Error tracing is enabled: command substitution, shell functions, and
+subshells invoked with @code{( @var{command} )} inherit the
+@code{ERR} trap.
+@end enumerate
+
+@item extglob
+If set, the extended pattern matching features described above
+(@pxref{Pattern Matching}) are enabled.
+
+@item extquote
+If set, @code{$'@var{string}'} and @code{$"@var{string}"} quoting is  
+performed within @code{$@{@var{parameter}@}} expansions                     
+enclosed in double quotes.  This option is enabled by default. 
+
+@item failglob
+If set, patterns which fail to match filenames during filename expansion
+result in an expansion error.
+
+@item force_fignore
+If set, the suffixes specified by the @env{FIGNORE} shell variable
+cause words to be ignored when performing word completion even if
+the ignored words are the only possible completions.
+@xref{Bash Variables}, for a description of @env{FIGNORE}.
+This option is enabled by default.
+
+@item globasciiranges
+If set, range expressions used in pattern matching bracket expressions
+(@pxref{Pattern Matching})
+behave as if in the traditional C locale when performing
+comparisons.  That is, the current locale's collating sequence
+is not taken into account, so
+@samp{b} will not collate between @samp{A} and @samp{B},
+and upper-case and lower-case ASCII characters will collate together.   
+
+@item globskipdots
+If set, filename expansion will never match the filenames
+@samp{.} and @samp{..},
+even if the pattern begins with a @samp{.}.
+This option is enabled by default.
+
+@item globstar
+If set, the pattern @samp{**} used in a filename expansion context will
+match all files and zero or more directories and subdirectories.
+If the pattern is followed by a @samp{/}, only directories and
+subdirectories match.
+
+@item gnu_errfmt
+If set, shell error messages are written in the standard @sc{gnu} error
+message format.
+
+@item histappend
+If set, the history list is appended to the file named by the value
+of the @env{HISTFILE}
+variable when the shell exits, rather than overwriting the file.
+
+@item histreedit
+If set, and Readline
+is being used, a user is given the opportunity to re-edit a
+failed history substitution.
+
+@item histverify
+If set, and Readline
+is being used, the results of history substitution are not immediately
+passed to the shell parser.  Instead, the resulting line is loaded into
+the Readline editing buffer, allowing further modification.
+
+@item hostcomplete
+If set, and Readline is being used, Bash will attempt to perform
+hostname completion when a word containing a @samp{@@} is being
+completed (@pxref{Commands For Completion}).  This option is enabled
+by default.
+
+@item huponexit
+If set, Bash will send @code{SIGHUP} to all jobs when an interactive
+login shell exits (@pxref{Signals}).
+
+@item inherit_errexit
+If set, command substitution inherits the value of the @code{errexit} option,
+instead of unsetting it in the subshell environment.
+This option is enabled when @sc{posix} mode is enabled.
+
+@item interactive_comments
+Allow a word beginning with @samp{#}
+to cause that word and all remaining characters on that
+line to be ignored in an interactive shell.
+This option is enabled by default.
+
+@item lastpipe
+If set, and job control is not active, the shell runs the last command of
+a pipeline not executed in the background in the current shell environment.
+
+@item lithist
+If enabled, and the @code{cmdhist}
+option is enabled, multi-line commands are saved to the history with
+embedded newlines rather than using semicolon separators where possible.
+
+@item localvar_inherit
+If set, local variables inherit the value and attributes of a variable of
+the same name that exists at a previous scope before any new value is
+assigned.  The @code{nameref} attribute is not inherited.
+
+@item localvar_unset
+If set, calling @code{unset} on local variables in previous function scopes
+marks them so subsequent lookups find them unset until that function
+returns. This is identical to the behavior of unsetting local variables
+at the current function scope.
+
+@item login_shell
+The shell sets this option if it is started as a login shell
+(@pxref{Invoking Bash}).
+The value may not be changed.
+
+@item mailwarn
+If set, and a file that Bash is checking for mail has been
+accessed since the last time it was checked, the message
+@code{"The mail in @var{mailfile} has been read"} is displayed.
+
+@item no_empty_cmd_completion
+If set, and Readline is being used, Bash will not attempt to search
+the @env{PATH} for possible completions when completion is attempted
+on an empty line.
+
+@item nocaseglob
+If set, Bash matches filenames in a case-insensitive fashion when
+performing filename expansion.
+
+@item nocasematch
+If set, Bash matches patterns in a case-insensitive fashion when
+performing matching while executing @code{case} or @code{[[}
+conditional commands (@pxref{Conditional Constructs},
+when performing pattern substitution word expansions,
+or when filtering possible completions as part of programmable completion.
+
+@item noexpand_translation
+If set, Bash
+encloses the translated results of $"..." quoting in single quotes
+instead of double quotes.
+If the string is not translated, this has no effect.
+
+@item nullglob
+If set, Bash allows filename patterns which match no
+files to expand to a null string, rather than themselves.
+
+@item patsub_replacement
+If set, Bash
+expands occurrences of @samp{&} in the replacement string of pattern
+substitution to the text matched by the pattern, as described
+above (@pxref{Shell Parameter Expansion}).
+This option is enabled by default.
+
+@item progcomp
+If set, the programmable completion facilities
+(@pxref{Programmable Completion}) are enabled.
+This option is enabled by default.
+
+@item progcomp_alias
+If set, and programmable completion is enabled, Bash treats a command
+name that doesn't have any completions as a possible alias and attempts
+alias expansion. If it has an alias, Bash attempts programmable
+completion using the command word resulting from the expanded alias.
+
+@item promptvars
+If set, prompt strings undergo
+parameter expansion, command substitution, arithmetic
+expansion, and quote removal after being expanded
+as described below (@pxref{Controlling the Prompt}).
+This option is enabled by default.
+
+@item restricted_shell
+The shell sets this option if it is started in restricted mode
+(@pxref{The Restricted Shell}).
+The value may not be changed.
+This is not reset when the startup files are executed, allowing
+the startup files to discover whether or not a shell is restricted.
+
+@item shift_verbose
+If this is set, the @code{shift}
+builtin prints an error message when the shift count exceeds the
+number of positional parameters.
+
+@item sourcepath
+If set, the @code{.} (@code{source}) builtin uses the value of @env{PATH}
+to find the directory containing the file supplied as an argument.
+This option is enabled by default.
+
+@item varredir_close
+If set, the shell automatically closes file descriptors assigned using the
+@code{@{varname@}} redirection syntax (@pxref{Redirections}) instead of
+leaving them open when the command completes.
+
+@item xpg_echo
+If set, the @code{echo} builtin expands backslash-escape sequences
+by default.
+
+@end table
+@end table
+
+@node Special Builtins
+@section Special Builtins
+@cindex special builtin
+
+For historical reasons, the @sc{posix} standard has classified
+several builtin commands as @emph{special}.
+When Bash is executing in @sc{posix} mode, the special builtins
+differ from other builtin commands in three respects:
+
+@enumerate
+@item
+Special builtins are found before shell functions during command lookup.
+
+@item
+If a special builtin returns an error status, a non-interactive shell exits.
+
+@item
+Assignment statements preceding the command stay in effect in the shell
+environment after the command completes.
+@end enumerate
+
+When Bash is not executing in @sc{posix} mode, these builtins behave no
+differently than the rest of the Bash builtin commands.
+The Bash @sc{posix} mode is described in @ref{Bash POSIX Mode}. 
+
+These are the @sc{posix} special builtins:
+@example
+@w{break : . continue eval exec exit export readonly return set}
+@w{shift trap unset}
+@end example

+
+@menu
+* Bourne Shell Variables::	Variables which Bash uses in the same way
+				as the Bourne Shell.
+* Bash Variables::		List of variables that exist in Bash.
+@end menu
+
+This chapter describes the shell variables that Bash uses.
+Bash automatically assigns default values to a number of variables.
+
+@node Bourne Shell Variables
+@section Bourne Shell Variables
+
+Bash uses certain shell variables in the same way as the Bourne shell.
+In some cases, Bash assigns a default value to the variable.
+
+@vtable @code
+
+@item CDPATH
+A colon-separated list of directories used as a search path for
+the @code{cd} builtin command.
+
+@item HOME
+The current user's home directory; the default for the @code{cd} builtin
+command.
+The value of this variable is also used by tilde expansion
+(@pxref{Tilde Expansion}).
+
+@item IFS
+A list of characters that separate fields; used when the shell splits
+words as part of expansion.
+
+@item MAIL
+If this parameter is set to a filename or directory name
+and the @env{MAILPATH} variable
+is not set, Bash informs the user of the arrival of mail in
+the specified file or Maildir-format directory.
+
+@item MAILPATH
+A colon-separated list of filenames which the shell periodically checks
+for new mail.
+Each list entry can specify the message that is printed when new mail
+arrives in the mail file by separating the filename from the message with
+a @samp{?}.
+When used in the text of the message, @code{$_} expands to the name of
+the current mail file.
+
+@item OPTARG
+The value of the last option argument processed by the @code{getopts} builtin.
+
+@item OPTIND
+The index of the last option argument processed by the @code{getopts} builtin.
+
+@item PATH
+A colon-separated list of directories in which the shell looks for
+commands.
+A zero-length (null) directory name in the value of @code{PATH} indicates the
+current directory.
+A null directory name may appear as two adjacent colons, or as an initial
+or trailing colon.
+
+@item PS1
+The primary prompt string.  The default value is @samp{\s-\v\$ }.
+@xref{Controlling the Prompt}, for the complete list of escape
+sequences that are expanded before @env{PS1} is displayed.
+
+@item PS2
+The secondary prompt string.  The default value is @samp{> }.
+@env{PS2} is expanded in the same way as @env{PS1} before being
+displayed.
+
+@end vtable
+
+@node Bash Variables
+@section Bash Variables
+
+These variables are set or used by Bash, but other shells
+do not normally treat them specially.
+
+A few variables used by Bash are described in different chapters:
+variables for controlling the job control facilities
+(@pxref{Job Control Variables}).
+
+@vtable @code
+
+@item _
+@vindex $_
+($_, an underscore.)
+At shell startup, set to the pathname used to invoke the
+shell or shell script being executed as passed in the environment
+or argument list.
+Subsequently, expands to the last argument to the previous simple
+command executed in the foreground, after expansion. 
+Also set to the full pathname used to invoke each command executed
+and placed in the environment exported to that command.
+When checking mail, this parameter holds the name of the mail file.
+
+@item BASH
+The full pathname used to execute the current instance of Bash.
+
+@item BASHOPTS
+A colon-separated list of enabled shell options.  Each word in
+the list is a valid argument for the @option{-s} option to the
+@code{shopt} builtin command (@pxref{The Shopt Builtin}).
+The options appearing in @env{BASHOPTS} are those reported
+as @samp{on} by @samp{shopt}.
+If this variable is in the environment when Bash
+starts up, each shell option in the list will be enabled before
+reading any startup files.  This variable is readonly.
+
+@item BASHPID
+Expands to the process ID of the current Bash process.
+This differs from @code{$$} under certain circumstances, such as subshells
+that do not require Bash to be re-initialized.
+Assignments to @env{BASHPID} have no effect.
+If @env{BASHPID}
+is unset, it loses its special properties, even if it is
+subsequently reset.
+
+@item BASH_ALIASES
+An associative array variable whose members correspond to the internal
+list of aliases as maintained by the @code{alias} builtin.
+(@pxref{Bourne Shell Builtins}).
+Elements added to this array appear in the alias list; however,
+unsetting array elements currently does not cause aliases to be removed
+from the alias list.
+If @env{BASH_ALIASES}
+is unset, it loses its special properties, even if it is
+subsequently reset.
+
+@item BASH_ARGC
+An array variable whose values are the number of parameters in each
+frame of the current bash execution call stack.  The number of
+parameters to the current subroutine (shell function or script executed
+with @code{.} or @code{source}) is at the top of the stack.  When a
+subroutine is executed, the number of parameters passed is pushed onto
+@code{BASH_ARGC}.
+The shell sets @code{BASH_ARGC} only when in extended debugging mode
+(see @ref{The Shopt Builtin}
+for a description of the @code{extdebug} option to the @code{shopt}
+builtin).
+Setting @code{extdebug} after the shell has started to execute a script,
+or referencing this variable when @code{extdebug} is not set,
+may result in inconsistent values.
+
+@item BASH_ARGV
+An array variable containing all of the parameters in the current bash
+execution call stack.  The final parameter of the last subroutine call
+is at the top of the stack; the first parameter of the initial call is
+at the bottom.  When a subroutine is executed, the parameters supplied
+are pushed onto @code{BASH_ARGV}.
+The shell sets @code{BASH_ARGV} only when in extended debugging mode
+(see @ref{The Shopt Builtin}
+for a description of the @code{extdebug} option to the @code{shopt}
+builtin).
+Setting @code{extdebug} after the shell has started to execute a script,
+or referencing this variable when @code{extdebug} is not set,
+may result in inconsistent values.
+
+@item BASH_ARGV0
+When referenced, this variable expands to the name of the shell or shell
+script (identical to @code{$0}; @xref{Special Parameters},
+for the description of special parameter 0).
+Assignment to @code{BASH_ARGV0}
+causes the value assigned to also be assigned to @code{$0}.
+If @env{BASH_ARGV0}
+is unset, it loses its special properties, even if it is
+subsequently reset.
+
+@item BASH_CMDS
+An associative array variable whose members correspond to the internal
+hash table of commands as maintained by the @code{hash} builtin
+(@pxref{Bourne Shell Builtins}).
+Elements added to this array appear in the hash table; however,
+unsetting array elements currently does not cause command names to be removed
+from the hash table.
+If @env{BASH_CMDS}
+is unset, it loses its special properties, even if it is
+subsequently reset.
+
+@item BASH_COMMAND
+The command currently being executed or about to be executed, unless the
+shell is executing a command as the result of a trap,
+in which case it is the command executing at the time of the trap.
+If @env{BASH_COMMAND}
+is unset, it loses its special properties, even if it is
+subsequently reset.
+
+@item BASH_COMPAT
+The value is used to set the shell's compatibility level.
+@xref{Shell Compatibility Mode}, for a description of the various
+compatibility levels and their effects.
+The value may be a decimal number (e.g., 4.2) or an integer (e.g., 42)
+corresponding to the desired compatibility level.
+If @env{BASH_COMPAT} is unset or set to the empty string, the compatibility
+level is set to the default for the current version.
+If @env{BASH_COMPAT} is set to a value that is not one of the valid
+compatibility levels, the shell prints an error message and sets the
+compatibility level to the default for the current version.
+The valid values correspond to the compatibility levels
+described below (@pxref{Shell Compatibility Mode}).
+For example, 4.2 and 42 are valid values that correspond
+to the @code{compat42} @code{shopt} option
+and set the compatibility level to 42.
+The current version is also a valid value.
+
+@item BASH_ENV
+If this variable is set when Bash is invoked to execute a shell
+script, its value is expanded and used as the name of a startup file
+to read before executing the script.  @xref{Bash Startup Files}.
+
+@item BASH_EXECUTION_STRING
+The command argument to the @option{-c} invocation option.
+
+@item BASH_LINENO
+An array variable whose members are the line numbers in source files
+where each corresponding member of @env{FUNCNAME} was invoked.
+@code{$@{BASH_LINENO[$i]@}} is the line number in the source file
+(@code{$@{BASH_SOURCE[$i+1]@}}) where
+@code{$@{FUNCNAME[$i]@}} was called (or @code{$@{BASH_LINENO[$i-1]@}} if
+referenced within another shell function). 
+Use @code{LINENO} to obtain the current line number.
+
+@item BASH_LOADABLES_PATH
+A colon-separated list of directories in which the shell looks for
+dynamically loadable builtins specified by the
+@code{enable} command.
+
+@item BASH_REMATCH
+An array variable whose members are assigned by the @samp{=~} binary
+operator to the @code{[[} conditional command
+(@pxref{Conditional Constructs}).
+The element with index 0 is the portion of the string
+matching the entire regular expression.
+The element with index @var{n} is the portion of the
+string matching the @var{n}th parenthesized subexpression.
+
+@item BASH_SOURCE
+An array variable whose members are the source filenames where the
+corresponding shell function names in the @code{FUNCNAME} array
+variable are defined.
+The shell function @code{$@{FUNCNAME[$i]@}} is defined in the file
+@code{$@{BASH_SOURCE[$i]@}} and called from @code{$@{BASH_SOURCE[$i+1]@}}
+
+@item BASH_SUBSHELL
+Incremented by one within each subshell or subshell environment when
+the shell begins executing in that environment.
+The initial value is 0.
+If @env{BASH_SUBSHELL}
+is unset, it loses its special properties, even if it is
+subsequently reset.
+
+@item BASH_VERSINFO
+A readonly array variable (@pxref{Arrays})
+whose members hold version information for this instance of Bash.
+The values assigned to the array members are as follows:
+
+@table @code
+
+@item BASH_VERSINFO[0]
+The major version number (the @dfn{release}).
+
+@item BASH_VERSINFO[1]
+The minor version number (the @dfn{version}).
+
+@item BASH_VERSINFO[2]
+The patch level.
+
+@item BASH_VERSINFO[3]
+The build version.
+
+@item BASH_VERSINFO[4]
+The release status (e.g., @code{beta1}).
+
+@item BASH_VERSINFO[5]
+The value of @env{MACHTYPE}.
+@end table
+
+@item BASH_VERSION
+The version number of the current instance of Bash.
+
+@item BASH_XTRACEFD
+If set to an integer corresponding to a valid file descriptor, Bash
+will write the trace output generated when @samp{set -x}
+is enabled to that file descriptor.
+This allows tracing output to be separated from diagnostic and error
+messages.
+The file descriptor is closed when @code{BASH_XTRACEFD} is unset or assigned
+a new value.
+Unsetting @code{BASH_XTRACEFD} or assigning it the empty string causes the
+trace output to be sent to the standard error.
+Note that setting @code{BASH_XTRACEFD} to 2 (the standard error file
+descriptor) and then unsetting it will result in the standard error
+being closed.
+
+@item CHILD_MAX
+Set the number of exited child status values for the shell to remember.
+Bash will not allow this value to be decreased below a @sc{posix}-mandated
+minimum, and there is a maximum value (currently 8192) that this may
+not exceed.
+The minimum value is system-dependent.
+
+@item COLUMNS
+Used by the @code{select} command to determine the terminal width
+when printing selection lists.
+Automatically set if the @code{checkwinsize} option is enabled
+(@pxref{The Shopt Builtin}), or in an interactive shell upon receipt of a
+@code{SIGWINCH}.
+
+@item COMP_CWORD
+An index into @env{$@{COMP_WORDS@}} of the word containing the current
+cursor position.
+This variable is available only in shell functions invoked by the
+programmable completion facilities (@pxref{Programmable Completion}).
+
+@item COMP_LINE
+The current command line.
+This variable is available only in shell functions and external
+commands invoked by the
+programmable completion facilities (@pxref{Programmable Completion}).
+
+@item COMP_POINT
+The index of the current cursor position relative to the beginning of
+the current command.
+If the current cursor position is at the end of the current command,
+the value of this variable is equal to @code{$@{#COMP_LINE@}}.
+This variable is available only in shell functions and external
+commands invoked by the
+programmable completion facilities (@pxref{Programmable Completion}).
+
+@item COMP_TYPE
+Set to an integer value corresponding to the type of completion attempted
+that caused a completion function to be called:
+@key{TAB}, for normal completion,
+@samp{?}, for listing completions after successive tabs,
+@samp{!}, for listing alternatives on partial word completion,
+@samp{@@}, to list completions if the word is not unmodified,
+or
+@samp{%}, for menu completion.
+This variable is available only in shell functions and external
+commands invoked by the
+programmable completion facilities (@pxref{Programmable Completion}).
+
+@item COMP_KEY
+The key (or final key of a key sequence) used to invoke the current
+completion function.
+
+@item COMP_WORDBREAKS
+The set of characters that the Readline library treats as word
+separators when performing word completion.
+If @env{COMP_WORDBREAKS}
+is unset, it loses its special properties,
+even if it is subsequently reset.
+
+@item COMP_WORDS
+An array variable consisting of the individual
+words in the current command line.
+The line is split into words as Readline would split it, using
+@code{COMP_WORDBREAKS} as described above.
+This variable is available only in shell functions invoked by the
+programmable completion facilities (@pxref{Programmable Completion}).
+
+@item COMPREPLY
+An array variable from which Bash reads the possible completions
+generated by a shell function invoked by the programmable completion
+facility (@pxref{Programmable Completion}).
+Each array element contains one possible completion.
+
+@item COPROC
+An array variable created to hold the file descriptors
+for output from and input to an unnamed coprocess (@pxref{Coprocesses}).
+
+@item DIRSTACK
+An array variable containing the current contents of the directory stack.
+Directories appear in the stack in the order they are displayed by the
+@code{dirs} builtin.
+Assigning to members of this array variable may be used to modify
+directories already in the stack, but the @code{pushd} and @code{popd}
+builtins must be used to add and remove directories.
+Assignment to this variable will not change the current directory.
+If @env{DIRSTACK}
+is unset, it loses its special properties, even if
+it is subsequently reset.
+
+@item EMACS
+If Bash finds this variable in the environment when the shell
+starts with value @samp{t}, it assumes that the shell is running in an
+Emacs shell buffer and disables line editing.
+
+@item ENV
+Expanded and executed similarly to @code{BASH_ENV}
+(@pxref{Bash Startup Files})
+when an interactive shell is invoked in
+@sc{posix} Mode (@pxref{Bash POSIX Mode}).
+
+@item EPOCHREALTIME
+Each time this parameter is referenced, it expands to the number of seconds
+since the Unix Epoch as a floating point value with micro-second granularity
+(see the documentation for the C library function @code{time} for the
+definition of Epoch).
+Assignments to @env{EPOCHREALTIME} are ignored.
+If @env{EPOCHREALTIME}
+is unset, it loses its special properties, even if
+it is subsequently reset.
+
+@item EPOCHSECONDS
+Each time this parameter is referenced, it expands to the number of seconds
+since the Unix Epoch (see the documentation for the C library function
+@code{time} for the definition of Epoch).
+Assignments to @env{EPOCHSECONDS} are ignored.
+If @env{EPOCHSECONDS}
+is unset, it loses its special properties, even if
+it is subsequently reset.
+
+@item EUID
+The numeric effective user id of the current user.  This variable
+is readonly.
+
+@item EXECIGNORE
+A colon-separated list of shell patterns (@pxref{Pattern Matching})
+defining the list of filenames to be ignored by command search using
+@code{PATH}.
+Files whose full pathnames match one of these patterns are not considered
+executable files for the purposes of completion and command execution
+via @code{PATH} lookup.
+This does not affect the behavior of the @code{[}, @code{test}, and @code{[[}
+commands.
+Full pathnames in the command hash table are not subject to @code{EXECIGNORE}.
+Use this variable to ignore shared library files that have the executable
+bit set, but are not executable files.
+The pattern matching honors the setting of the @code{extglob} shell 
+option.
+
+@item FCEDIT
+The editor used as a default by the @option{-e} option to the @code{fc}
+builtin command.
+
+@item FIGNORE
+A colon-separated list of suffixes to ignore when performing
+filename completion.
+A filename whose suffix matches one of the entries in 
+@env{FIGNORE}
+is excluded from the list of matched filenames.  A sample
+value is @samp{.o:~}
+
+@item FUNCNAME
+An array variable containing the names of all shell functions
+currently in the execution call stack.
+The element with index 0 is the name of any currently-executing
+shell function.
+The bottom-most element (the one with the highest index)
+is @code{"main"}.
+This variable exists only when a shell function is executing.
+Assignments to @env{FUNCNAME} have no effect.
+If @env{FUNCNAME}
+is unset, it loses its special properties, even if
+it is subsequently reset.
+
+This variable can be used with @code{BASH_LINENO} and @code{BASH_SOURCE}.
+Each element of @code{FUNCNAME} has corresponding elements in
+@code{BASH_LINENO} and @code{BASH_SOURCE} to describe the call stack.
+For instance, @code{$@{FUNCNAME[$i]@}} was called from the file
+@code{$@{BASH_SOURCE[$i+1]@}} at line number @code{$@{BASH_LINENO[$i]@}}.
+The @code{caller} builtin displays the current call stack using this
+information.
+
+@item FUNCNEST
+If set to a numeric value greater than 0, defines a maximum function
+nesting level.  Function invocations that exceed this nesting level
+will cause the current command to abort.
+
+@item GLOBIGNORE
+A colon-separated list of patterns defining the set of file names to
+be ignored by filename expansion.
+If a file name matched by a filename expansion pattern also matches one
+of the patterns in @env{GLOBIGNORE}, it is removed from the list
+of matches.
+The pattern matching honors the setting of the @code{extglob} shell
+option.
+
+@item GROUPS
+An array variable containing the list of groups of which the current    
+user is a member.
+Assignments to @env{GROUPS} have no effect.
+If @env{GROUPS}
+is unset, it loses its special properties, even if it is
+subsequently reset.
+
+@item histchars
+Up to three characters which control history expansion, quick
+substitution, and tokenization (@pxref{History Interaction}).
+The first character is the
+@dfn{history expansion} character, that is, the character which signifies the
+start of a history expansion, normally @samp{!}.  The second character is the
+character which signifies `quick substitution' when seen as the first
+character on a line, normally @samp{^}.  The optional third character is the
+character which indicates that the remainder of the line is a comment when
+found as the first character of a word, usually @samp{#}.  The history
+comment character causes history substitution to be skipped for the
+remaining words on the line.  It does not necessarily cause the shell
+parser to treat the rest of the line as a comment.
+
+@item HISTCMD
+The history number, or index in the history list, of the current
+command.
+Assignments to @env{HISTCMD} are ignored.
+If @env{HISTCMD}
+is unset, it loses its special properties,
+even if it is subsequently reset.
+
+@item HISTCONTROL
+A colon-separated list of values controlling how commands are saved on
+the history list.
+If the list of values includes @samp{ignorespace}, lines which begin
+with a space character are not saved in the history list.
+A value of @samp{ignoredups} causes lines which match the previous
+history entry to not be saved.
+A value of @samp{ignoreboth} is shorthand for
+@samp{ignorespace} and @samp{ignoredups}.
+A value of @samp{erasedups} causes all previous lines matching the
+current line to be removed from the history list before that line
+is saved.
+Any value not in the above list is ignored.
+If @env{HISTCONTROL} is unset, or does not include a valid value, 
+all lines read by the shell parser are saved on the history list, 
+subject to the value of @env{HISTIGNORE}.
+The second and subsequent lines of a multi-line compound command are
+not tested, and are added to the history regardless of the value of
+@env{HISTCONTROL}.
+
+@item HISTFILE
+The name of the file to which the command history is saved.  The
+default value is @file{~/.bash_history}.
+
+@item HISTFILESIZE
+The maximum number of lines contained in the history file.
+When this variable is assigned a value, the history file is truncated,
+if necessary, to contain no more than that number of lines
+by removing the oldest entries.
+The history file is also truncated to this size after
+writing it when a shell exits.
+If the value is 0, the history file is truncated to zero size.
+Non-numeric values and numeric values less than zero inhibit truncation.
+The shell sets the default value to the value of @env{HISTSIZE}
+after reading any startup files.
+
+@item HISTIGNORE
+A colon-separated list of patterns used to decide which command
+lines should be saved on the history list.  Each pattern is
+anchored at the beginning of the line and must match the complete
+line (no implicit @samp{*} is appended).  Each pattern is tested
+against the line after the checks specified by @env{HISTCONTROL}
+are applied.  In addition to the normal shell pattern matching
+characters, @samp{&} matches the previous history line.  @samp{&}
+may be escaped using a backslash; the backslash is removed
+before attempting a match. 
+The second and subsequent lines of a multi-line compound command are
+not tested, and are added to the history regardless of the value of
+@env{HISTIGNORE}.
+The pattern matching honors the setting of the @code{extglob} shell
+option.
+
+@env{HISTIGNORE} subsumes the function of @env{HISTCONTROL}.  A
+pattern of @samp{&} is identical to @code{ignoredups}, and a
+pattern of @samp{[ ]*} is identical to @code{ignorespace}. 
+Combining these two patterns, separating them with a colon,
+provides the functionality of @code{ignoreboth}. 
+
+@item HISTSIZE
+The maximum number of commands to remember on the history list.
+If the value is 0, commands are not saved in the history list.
+Numeric values less than zero result in every command being saved
+on the history list (there is no limit).
+The shell sets the default value to 500 after reading any startup files.
+
+@item HISTTIMEFORMAT
+If this variable is set and not null, its value is used as a format string
+for @code{strftime} to print the time stamp associated with each history
+entry displayed by the @code{history} builtin.
+If this variable is set, time stamps are written to the history file so
+they may be preserved across shell sessions.
+This uses the history comment character to distinguish timestamps from
+other history lines.
+
+@item HOSTFILE
+Contains the name of a file in the same format as @file{/etc/hosts} that
+should be read when the shell needs to complete a hostname.
+The list of possible hostname completions may be changed while the shell
+is running;
+the next time hostname completion is attempted after the
+value is changed, Bash adds the contents of the new file to the
+existing list.
+If @env{HOSTFILE} is set, but has no value, or does not name a readable file,
+Bash attempts to read 
+@file{/etc/hosts} to obtain the list of possible hostname completions.
+When @env{HOSTFILE} is unset, the hostname list is cleared.
+
+@item HOSTNAME
+The name of the current host.
+
+@item HOSTTYPE
+A string describing the machine Bash is running on.
+
+@item IGNOREEOF
+Controls the action of the shell on receipt of an @code{EOF} character
+as the sole input.  If set, the value denotes the number
+of consecutive @code{EOF} characters that can be read as the
+first character on an input line
+before the shell will exit.  If the variable exists but does not
+have a numeric value, or has no value, then the default is 10.
+If the variable does not exist, then @code{EOF} signifies the end of 
+input to the shell.  This is only in effect for interactive shells.
+
+@item INPUTRC
+The name of the Readline initialization file, overriding the default
+of @file{~/.inputrc}.
+
+@item INSIDE_EMACS
+If Bash finds this variable in the environment when the shell
+starts, it assumes that the shell is running in an Emacs shell buffer
+and may disable line editing depending on the value of @env{TERM}.
+
+@item LANG  
+Used to determine the locale category for any category not specifically
+selected with a variable starting with @code{LC_}.
+
+@item LC_ALL
+This variable overrides the value of @env{LANG} and any other
+@code{LC_} variable specifying a locale category.
+
+@item LC_COLLATE
+This variable determines the collation order used when sorting the
+results of filename expansion, and
+determines the behavior of range expressions, equivalence classes,
+and collating sequences within filename expansion and pattern matching
+(@pxref{Filename Expansion}).
+
+@item LC_CTYPE
+This variable determines the interpretation of characters and the
+behavior of character classes within filename expansion and pattern
+matching (@pxref{Filename Expansion}).
+
+@item LC_MESSAGES
+This variable determines the locale used to translate double-quoted
+strings preceded by a @samp{$} (@pxref{Locale Translation}).
+
+@item LC_NUMERIC
+This variable determines the locale category used for number formatting.
+
+@item LC_TIME
+This variable determines the locale category used for data and time
+formatting.
+
+@item LINENO
+The line number in the script or shell function currently executing.
+If @env{LINENO}
+is unset, it loses its special properties, even if it is
+subsequently reset.
+
+@item LINES
+Used by the @code{select} command to determine the column length
+for printing selection lists.
+Automatically set if the @code{checkwinsize} option is enabled
+(@pxref{The Shopt Builtin}), or in an interactive shell upon receipt of a
+@code{SIGWINCH}.
+
+@item MACHTYPE
+A string that fully describes the system type on which Bash
+is executing, in the standard @sc{gnu} @var{cpu-company-system} format.
+
+@item MAILCHECK
+How often (in seconds) that the shell should check for mail in the
+files specified in the @env{MAILPATH} or @env{MAIL} variables.
+The default is 60 seconds.  When it is time to check
+for mail, the shell does so before displaying the primary prompt.
+If this variable is unset, or set to a value that is not a number
+greater than or equal to zero, the shell disables mail checking.
+
+@item MAPFILE
+An array variable created to hold the text read by the
+@code{mapfile} builtin when no variable name is supplied.
+
+@item OLDPWD
+The previous working directory as set by the @code{cd} builtin.
+
+@item OPTERR
+If set to the value 1, Bash displays error messages
+generated by the @code{getopts} builtin command.
+
+@item OSTYPE
+A string describing the operating system Bash is running on.
+
+@item PIPESTATUS
+An array variable (@pxref{Arrays})
+containing a list of exit status values from the processes
+in the most-recently-executed foreground pipeline (which may
+contain only a single command).
+
+@item POSIXLY_CORRECT
+If this variable is in the environment when Bash starts, the shell
+enters @sc{posix} mode (@pxref{Bash POSIX Mode}) before reading the
+startup files, as if the @option{--posix} invocation option had been supplied.
+If it is set while the shell is running, Bash enables @sc{posix} mode,
+as if the command
+@example
+@code{set -o posix}
+@end example
+@noindent
+had been executed.
+When the shell enters @sc{posix} mode, it sets this variable if it was
+not already set.
+
+@item PPID
+The process @sc{id} of the shell's parent process.  This variable
+is readonly.
+
+@item PROMPT_COMMAND
+If this variable is set, and is an array,
+the value of each set element is interpreted as a command to execute
+before printing the primary prompt (@env{$PS1}).
+If this is set but not an array variable,
+its value is used as a command to execute instead.
+
+@item PROMPT_DIRTRIM
+If set to a number greater than zero, the value is used as the number of
+trailing directory components to retain when expanding the @code{\w} and
+@code{\W} prompt string escapes (@pxref{Controlling the Prompt}).
+Characters removed are replaced with an ellipsis.
+
+@item PS0
+The value of this parameter is expanded like @env{PS1}
+and displayed by interactive shells after reading a command
+and before the command is executed.
+
+@item PS3
+The value of this variable is used as the prompt for the
+@code{select} command.  If this variable is not set, the
+@code{select} command prompts with @samp{#? }
+
+@item PS4
+The value of this parameter is expanded like @env{PS1}
+and the expanded value is the prompt printed before the command line
+is echoed when the @option{-x} option is set (@pxref{The Set Builtin}).
+The first character of the expanded value is replicated multiple times,
+as necessary, to indicate multiple levels of indirection.
+The default is @samp{+ }.
+
+@item PWD
+The current working directory as set by the @code{cd} builtin.
+
+@item RANDOM
+Each time this parameter is referenced, it expands to a random integer
+between 0 and 32767. Assigning a value to this
+variable seeds the random number generator.
+If @env{RANDOM}
+is unset, it loses its special properties, even if it is
+subsequently reset.
+
+@item READLINE_ARGUMENT
+Any numeric argument given to a Readline command that was defined using
+@samp{bind -x} (@pxref{Bash Builtins}
+when it was invoked.
+
+@item READLINE_LINE
+The contents of the Readline line buffer, for use
+with @samp{bind -x} (@pxref{Bash Builtins}).
+
+@item READLINE_MARK
+The position of the @dfn{mark} (saved insertion point) in the
+Readline line buffer, for use
+with @samp{bind -x} (@pxref{Bash Builtins}).
+The characters between the insertion point and the mark are often
+called the @dfn{region}.
+
+@item READLINE_POINT
+The position of the insertion point in the Readline line buffer, for use
+with @samp{bind -x} (@pxref{Bash Builtins}).
+
+@item REPLY
+The default variable for the @code{read} builtin.
+
+@item SECONDS
+This variable expands to the number of seconds since the shell was started. 
+Assignment to this variable resets the count to the value assigned, and the
+expanded value becomes the value assigned plus the number of seconds
+since the assignment.
+The number of seconds at shell invocation and the current time are always
+determined by querying the system clock.
+If @env{SECONDS}
+is unset, it loses its special properties,
+even if it is subsequently reset.
+
+@item SHELL
+This environment variable expands to the full pathname to the shell.
+If it is not set when the shell starts,
+Bash assigns to it the full pathname of the current user's login shell.
+
+@item SHELLOPTS
+A colon-separated list of enabled shell options.  Each word in
+the list is a valid argument for the @option{-o} option to the
+@code{set} builtin command (@pxref{The Set Builtin}).
+The options appearing in @env{SHELLOPTS} are those reported
+as @samp{on} by @samp{set -o}.
+If this variable is in the environment when Bash
+starts up, each shell option in the list will be enabled before
+reading any startup files.  This variable is readonly.
+
+@item SHLVL
+Incremented by one each time a new instance of Bash is started.  This is
+intended to be a count of how deeply your Bash shells are nested.
+
+@item SRANDOM
+This variable expands to a 32-bit pseudo-random number each time it is
+referenced. The random number generator is not linear on systems that
+support @file{/dev/urandom} or @code{arc4random}, so each returned number
+has no relationship to the numbers preceding it.
+The random number generator cannot be seeded, so assignments to this
+variable have no effect.
+If @env{SRANDOM}
+is unset, it loses its special properties,
+even if it is subsequently reset.
+
+@item TIMEFORMAT
+The value of this parameter is used as a format string specifying
+how the timing information for pipelines prefixed with the @code{time}
+reserved word should be displayed.
+The @samp{%} character introduces an
+escape sequence that is expanded to a time value or other
+information.
+The escape sequences and their meanings are as
+follows; the braces denote optional portions. 
+
+@table @code
+
+@item %%
+A literal @samp{%}.
+
+@item %[@var{p}][l]R
+The elapsed time in seconds. 
+
+@item %[@var{p}][l]U
+The number of CPU seconds spent in user mode. 
+
+@item %[@var{p}][l]S
+The number of CPU seconds spent in system mode. 
+
+@item %P
+The CPU percentage, computed as (%U + %S) / %R. 
+@end table
+
+The optional @var{p} is a digit specifying the precision, the number of
+fractional digits after a decimal point.
+A value of 0 causes no decimal point or fraction to be output.
+At most three places after the decimal point may be specified; values
+of @var{p} greater than 3 are changed to 3.
+If @var{p} is not specified, the value 3 is used. 
+
+The optional @code{l} specifies a longer format, including minutes, of
+the form @var{MM}m@var{SS}.@var{FF}s.
+The value of @var{p} determines whether or not the fraction is included. 
+
+If this variable is not set, Bash acts as if it had the value
+@example
+@code{$'\nreal\t%3lR\nuser\t%3lU\nsys\t%3lS'}
+@end example
+If the value is null, no timing information is displayed.
+A trailing newline is added when the format string is displayed.
+
+@item TMOUT
+If set to a value greater than zero, @code{TMOUT} is treated as the
+default timeout for the @code{read} builtin (@pxref{Bash Builtins}).
+The @code{select} command (@pxref{Conditional Constructs}) terminates
+if input does not arrive after @code{TMOUT} seconds when input is coming
+from a terminal.
+
+In an interactive shell, the value is interpreted as
+the number of seconds to wait for a line of input after issuing
+the primary prompt.
+Bash
+terminates after waiting for that number of seconds if a complete
+line of input does not arrive.
+
+@item TMPDIR
+If set, Bash uses its value as the name of a directory in which
+Bash creates temporary files for the shell's use.
+
+@item UID
+The numeric real user id of the current user.  This variable is readonly.

+@end example
+
+All of the single-character options used with the @code{set} builtin
+(@pxref{The Set Builtin}) can be used as options when the shell is invoked.
+In addition, there are several multi-character
+options that you can use.  These options must appear on the command
+line before the single-character options to be recognized. 
+
+@table @code
+@item --debugger
+Arrange for the debugger profile to be executed before the shell
+starts.  Turns on extended debugging mode (see @ref{The Shopt Builtin}
+for a description of the @code{extdebug} option to the @code{shopt}
+builtin).
+
+@item --dump-po-strings
+A list of all double-quoted strings preceded by @samp{$}
+is printed on the standard output
+in the @sc{gnu} @code{gettext} PO (portable object) file format.
+Equivalent to @option{-D} except for the output format.
+
+@item --dump-strings
+Equivalent to @option{-D}.
+
+@item --help
+Display a usage message on standard output and exit successfully.
+
+@item --init-file @var{filename}
+@itemx --rcfile @var{filename}
+Execute commands from @var{filename} (instead of @file{~/.bashrc})
+in an interactive shell.
+
+@item --login
+Equivalent to @option{-l}.
+
+@item --noediting
+Do not use the @sc{gnu} Readline library (@pxref{Command Line Editing})
+to read  command lines when the shell is interactive.
+
+@item --noprofile
+Don't load the system-wide startup file @file{/etc/profile}
+or any of the personal initialization files
+@file{~/.bash_profile}, @file{~/.bash_login}, or @file{~/.profile}
+when Bash is invoked as a login shell.
+
+@item --norc
+Don't read the @file{~/.bashrc} initialization file in an
+interactive shell.  This is on by default if the shell is
+invoked as @code{sh}.
+
+@item --posix
+Change the behavior of Bash where the default operation differs
+from the @sc{posix} standard to match the standard.  This
+is intended to make Bash behave as a strict superset of that
+standard.  @xref{Bash POSIX Mode}, for a description of the Bash
+@sc{posix} mode.
+
+@item --restricted
+Make the shell a restricted shell (@pxref{The Restricted Shell}).
+
+@item --verbose
+Equivalent to @option{-v}.  Print shell input lines as they're read.
+
+@item --version
+Show version information for this instance of
+Bash on the standard output and exit successfully.
+@end table
+
+There are several single-character options that may be supplied at
+invocation which are not available with the @code{set} builtin.
+
+@table @code
+@item -c
+Read and execute commands from the first non-option argument
+@var{command_string}, then exit. 
+If there are arguments after the @var{command_string},
+the first argument is assigned to @code{$0}
+and any remaining arguments are assigned to the positional parameters.
+The assignment to @code{$0} sets the name of the shell, which is used
+in warning and error messages.
+
+@item -i
+Force the shell to run interactively.  Interactive shells are
+described in @ref{Interactive Shells}.
+
+@item -l
+Make this shell act as if it had been directly invoked by login.
+When the shell is interactive, this is equivalent to starting a
+login shell with @samp{exec -l bash}.
+When the shell is not interactive, the login shell startup files will
+be executed.
+@samp{exec bash -l} or @samp{exec bash --login}
+will replace the current shell with a Bash login shell.
+@xref{Bash Startup Files}, for a description of the special behavior
+of a login shell.
+
+@item -r
+Make the shell a restricted shell (@pxref{The Restricted Shell}).
+
+@item -s
+If this option is present, or if no arguments remain after option
+processing, then commands are read from the standard input.
+This option allows the positional parameters to be set
+when invoking an interactive shell or when reading input
+through a pipe.
+
+@item -D
+A list of all double-quoted strings preceded by @samp{$}
+is printed on the standard output.
+These are the strings that
+are subject to language translation when the current locale
+is not @code{C} or @code{POSIX} (@pxref{Locale Translation}).
+This implies the @option{-n} option; no commands will be executed.
+
+@item [-+]O [@var{shopt_option}]
+@var{shopt_option} is one of the shell options accepted by the
+@code{shopt} builtin (@pxref{The Shopt Builtin}).
+If @var{shopt_option} is present, @option{-O} sets the value of that option;
+@option{+O} unsets it.  
+If @var{shopt_option} is not supplied, the names and values of the shell
+options accepted by @code{shopt} are printed on the standard output.
+If the invocation option is @option{+O}, the output is displayed in a format
+that may be reused as input.
+
+@item --
+A @code{--} signals the end of options and disables further option
+processing.
+Any arguments after the @code{--} are treated as filenames and arguments.
+@end table
+
+@cindex login shell
+A @emph{login} shell is one whose first character of argument zero is
+@samp{-}, or one invoked with the @option{--login} option.
+
+@cindex interactive shell
+An @emph{interactive} shell is one started without non-option arguments,
+unless @option{-s} is specified,
+without specifying the @option{-c} option, and whose input and output are both
+connected to terminals (as determined by @code{isatty(3)}), or one
+started with the @option{-i} option.  @xref{Interactive Shells}, for more
+information.
+
+If arguments remain after option processing, and neither the
+@option{-c} nor the @option{-s}
+option has been supplied, the first argument is assumed to
+be the name of a file containing shell commands (@pxref{Shell Scripts}).
+When Bash is invoked in this fashion, @code{$0}
+is set to the name of the file, and the positional parameters
+are set to the remaining arguments.
+Bash reads and executes commands from this file, then exits.   
+Bash's exit status is the exit status of the last command executed
+in the script.  If no commands are executed, the exit status is 0.

+This section describes how Bash executes its startup files.
+If any of the files exist but cannot be read, Bash reports an error.
+Tildes are expanded in filenames as described above under
+Tilde Expansion (@pxref{Tilde Expansion}).
+
+Interactive shells are described in @ref{Interactive Shells}.
+
+@subsubheading Invoked as an interactive login shell, or with @option{--login}
+
+When Bash is invoked as an interactive login shell, or as a
+non-interactive shell with the @option{--login} option, it first reads and
+executes commands from the file @file{/etc/profile}, if that file exists.
+After reading that file, it looks for @file{~/.bash_profile},
+@file{~/.bash_login}, and @file{~/.profile}, in that order, and reads
+and executes commands from the first one that exists and is readable.
+The @option{--noprofile} option may be used when the shell is started to
+inhibit this behavior.
+
+When an interactive login shell exits,
+or a non-interactive login shell executes the @code{exit} builtin command,
+Bash reads and executes commands from
+the file @file{~/.bash_logout}, if it exists.
+
+@subsubheading Invoked as an interactive non-login shell
+
+When an interactive shell that is not a login shell is started, Bash
+reads and executes commands from @file{~/.bashrc}, if that file exists.
+This may be inhibited by using the @option{--norc} option.
+The @option{--rcfile @var{file}} option will force Bash to read and
+execute commands from @var{file} instead of @file{~/.bashrc}.
+
+So, typically, your @file{~/.bash_profile} contains the line
+@example
+@code{if [ -f ~/.bashrc ]; then . ~/.bashrc; fi}
+@end example
+@noindent
+after (or before) any login-specific initializations.
+
+@subsubheading Invoked non-interactively
+
+When Bash is started non-interactively, to run a shell script,
+for example, it looks for the variable @env{BASH_ENV} in the environment,
+expands its value if it appears there, and uses the expanded value as
+the name of a file to read and execute.  Bash behaves as if the
+following command were executed:
+@example
+@code{if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi}
+@end example
+@noindent
+but the value of the @env{PATH} variable is not used to search for the
+filename.
+
+As noted above, if a non-interactive shell is invoked with the
+@option{--login} option, Bash attempts to read and execute commands from the
+login shell startup files. 
+
+@subsubheading Invoked with name @code{sh}
+
+If Bash is invoked with the name @code{sh}, it tries to mimic the
+startup behavior of historical versions of @code{sh} as closely as
+possible, while conforming to the @sc{posix} standard as well.
+
+When invoked as an interactive login shell, or as a non-interactive
+shell with the @option{--login} option, it first attempts to read
+and execute commands from @file{/etc/profile} and @file{~/.profile}, in
+that order.
+The @option{--noprofile} option may be used to inhibit this behavior.
+When invoked as an interactive shell with the name @code{sh}, Bash
+looks for the variable @env{ENV}, expands its value if it is defined,
+and uses the expanded value as the name of a file to read and execute.
+Since a shell invoked as @code{sh} does not attempt to read and execute
+commands from any other startup files, the @option{--rcfile} option has
+no effect.
+A non-interactive shell invoked with the name @code{sh} does not attempt
+to read any other startup files.
+
+When invoked as @code{sh}, Bash enters @sc{posix} mode after
+the startup files are read.
+
+@subsubheading Invoked in @sc{posix} mode
+
+When Bash is started in @sc{posix} mode, as with the
+@option{--posix} command line option, it follows the @sc{posix} standard
+for startup files.
+In this mode, interactive shells expand the @env{ENV} variable
+and commands are read and executed from the file whose name is the
+expanded value.
+No other startup files are read.
+
+@subsubheading Invoked by remote shell daemon
+
+Bash attempts to determine when it is being run with its standard input
+connected to a network connection, as when executed by
+the historical remote shell daemon, usually @code{rshd},
+or the secure shell daemon @code{sshd}.
+If Bash
+determines it is being run non-interactively in this fashion,
+it reads and executes commands from @file{~/.bashrc}, if that
+file exists and is readable.
+It will not do this if invoked as @code{sh}.
+The @option{--norc} option may be used to inhibit this behavior, and the
+@option{--rcfile} option may be used to force another file to be read, but
+neither @code{rshd} nor @code{sshd} generally invoke the shell with those
+options or allow them to be specified.
+
+@subsubheading Invoked with unequal effective and real @sc{uid/gid}s
+
+If Bash is started with the effective user (group) id not equal to the
+real user (group) id, and the @option{-p} option is not supplied, no startup
+files are read, shell functions are not inherited from the environment,
+the @env{SHELLOPTS}, @env{BASHOPTS}, @env{CDPATH}, and @env{GLOBIGNORE}
+variables, if they appear in the environment, are ignored, and the effective
+user id is set to the real user id.
+If the @option{-p} option is supplied at invocation, the startup behavior is
+the same, but the effective user id is not reset.

+@node What is an Interactive Shell?
+@subsection What is an Interactive Shell?
+
+An interactive shell
+is one started without non-option arguments
+(unless @option{-s} is specified)
+and without specifying the @option{-c} option,
+whose input and error output are both
+connected to terminals (as determined by @code{isatty(3)}),
+or one started with the @option{-i} option.
+
+An interactive shell generally reads from and writes to a user's
+terminal.
+
+The @option{-s} invocation option may be used to set the positional parameters
+when an interactive shell is started.
+
+@node Is this Shell Interactive?
+@subsection Is this Shell Interactive?
+
+To determine within a startup script whether or not Bash is
+running interactively,
+test the value of the @samp{-} special parameter.
+It contains @code{i} when the shell is interactive.  For example:
+
+@example
+case "$-" in
+*i*)	echo This shell is interactive ;;
+*)	echo This shell is not interactive ;;
+esac
+@end example
+
+Alternatively, startup scripts may examine the variable
+@env{PS1}; it is unset in non-interactive shells, and set in
+interactive shells.  Thus:
+
+@example
+if [ -z "$PS1" ]; then
+        echo This shell is not interactive
+else
+        echo This shell is interactive
+fi
+@end example
+
+@node Interactive Shell Behavior
+@subsection Interactive Shell Behavior
+
+When the shell is running interactively, it changes its behavior in
+several ways.
+
+@enumerate
+@item
+Startup files are read and executed as described in @ref{Bash Startup Files}.
+
+@item
+Job Control (@pxref{Job Control}) is enabled by default.  When job
+control is in effect, Bash ignores the keyboard-generated job control
+signals @code{SIGTTIN}, @code{SIGTTOU}, and @code{SIGTSTP}.
+
+@item
+Bash expands and displays @env{PS1} before reading the first line
+of a command, and expands and displays @env{PS2} before reading the
+second and subsequent lines of a multi-line command.
+Bash expands and displays @env{PS0} after it reads a command but before
+executing it.
+See @ref{Controlling the Prompt}, for a complete list of prompt
+string escape sequences.
+
+@item
+Bash executes the values of the set elements of the @env{PROMPT_COMMAND}
+array variable as commands before printing the primary prompt, @env{$PS1}
+(@pxref{Bash Variables}).
+
+@item
+Readline (@pxref{Command Line Editing}) is used to read commands from
+the user's terminal.
+
+@item
+Bash inspects the value of the @code{ignoreeof} option to @code{set -o}
+instead of exiting immediately when it receives an @code{EOF} on its
+standard input when reading a command (@pxref{The Set Builtin}).
+
+@item
+Command history (@pxref{Bash History Facilities})
+and history expansion (@pxref{History Interaction})
+are enabled by default.
+Bash will save the command history to the file named by @env{$HISTFILE}
+when a shell with history enabled exits.
+
+@item
+Alias expansion (@pxref{Aliases}) is performed by default.
+
+@item
+In the absence of any traps, Bash ignores @code{SIGTERM}
+(@pxref{Signals}).
+
+@item
+In the absence of any traps, @code{SIGINT} is caught and handled
+(@pxref{Signals}).
+@code{SIGINT} will interrupt some shell builtins.
+
+@item
+An interactive login shell sends a @code{SIGHUP} to all jobs on exit
+if the @code{huponexit} shell option has been enabled (@pxref{Signals}).
+
+@item
+The @option{-n} invocation option is ignored, and @samp{set -n} has
+no effect (@pxref{The Set Builtin}).
+
+@item
+Bash will check for mail periodically, depending on the values of the
+@env{MAIL}, @env{MAILPATH}, and @env{MAILCHECK} shell variables
+(@pxref{Bash Variables}).
+
+@item
+Expansion errors due to references to unbound shell variables after
+@samp{set -u} has been enabled will not cause the shell to exit
+(@pxref{The Set Builtin}).
+
+@item
+The shell will not exit on expansion errors caused by @var{var} being unset
+or null in @code{$@{@var{var}:?@var{word}@}} expansions
+(@pxref{Shell Parameter Expansion}).
+
+@item
+Redirection errors encountered by shell builtins will not cause the
+shell to exit.
+
+@item
+When running in @sc{posix} mode, a special builtin returning an error
+status will not cause the shell to exit (@pxref{Bash POSIX Mode}).
+
+@item
+A failed @code{exec} will not cause the shell to exit
+(@pxref{Bourne Shell Builtins}).
+
+@item
+Parser syntax errors will not cause the shell to exit.
+
+@item
+If the @code{cdspell} shell option is enabled, the shell will attempt
+simple spelling correction for directory arguments to the @code{cd}
+builtin (see the description of the @code{cdspell}
+option to the @code{shopt} builtin in @ref{The Shopt Builtin}).
+The @code{cdspell} option is only effective in interactive shells.
+
+@item
+The shell will check the value of the @env{TMOUT} variable and exit
+if a command is not read within the specified number of seconds after
+printing @env{$PS1} (@pxref{Bash Variables}).
+
+@end enumerate
+
+@node Bash Conditional Expressions
+@section Bash Conditional Expressions
+@cindex expressions, conditional
+
+Conditional expressions are used by the @code{[[} compound command
+(@pxref{Conditional Constructs})
+and the @code{test} and @code{[} builtin commands
+(@pxref{Bourne Shell Builtins}).
+The @code{test}
+and @code{[} commands determine their behavior based on the number
+of arguments; see the descriptions of those commands for any other
+command-specific actions.
+
+Expressions may be unary or binary,
+and are formed from the following primaries.
+Unary expressions are often used to examine the status of a file.
+There are string operators and numeric comparison operators as well.
+Bash handles several filenames specially when they are used in
+expressions.
+If the operating system on which Bash is running provides these
+special files, Bash will use them; otherwise it will emulate them
+internally with this behavior:
+If the @var{file} argument to one of the primaries is of the form
+@file{/dev/fd/@var{N}}, then file descriptor @var{N} is checked.
+If the @var{file} argument to one of the primaries is one of
+@file{/dev/stdin}, @file{/dev/stdout}, or @file{/dev/stderr}, file
+descriptor 0, 1, or 2, respectively, is checked.
+
+When used with @code{[[}, the @samp{<} and @samp{>} operators sort
+lexicographically using the current locale.
+The @code{test} command uses ASCII ordering.
+
+Unless otherwise specified, primaries that operate on files follow symbolic
+links and operate on the target of the link, rather than the link itself.

+
+Shell variables are allowed as operands; parameter expansion is
+performed before the expression is evaluated. 
+Within an expression, shell variables may also be referenced by name
+without using the parameter expansion syntax.
+A shell variable that is null or unset evaluates to 0 when referenced
+by name without using the parameter expansion syntax.
+The value of a variable is evaluated as an arithmetic expression
+when it is referenced, or when a variable which has been given the  
+@code{integer} attribute using @samp{declare -i} is assigned a value.
+A null value evaluates to 0.
+A shell variable need not have its @code{integer} attribute turned on
+to be used in an expression.
+
+Integer constants follow the C language definition, without suffixes or
+character constants.
+Constants with a leading 0 are interpreted as octal numbers.
+A leading @samp{0x} or @samp{0X} denotes hexadecimal.  Otherwise,
+numbers take the form [@var{base}@code{#}]@var{n}, where the optional @var{base}
+is a decimal number between 2 and 64 representing the arithmetic
+base, and @var{n} is a number in that base.
+If @var{base}@code{#} is omitted, then base 10 is used.
+When specifying @var{n},
+if a non-digit is required,
+the digits greater than 9 are represented by the lowercase letters,
+the uppercase letters, @samp{@@}, and @samp{_}, in that order.
+If @var{base} is less than or equal to 36, lowercase and uppercase
+letters may be used interchangeably to represent numbers between 10
+and 35.
+
+Operators are evaluated in order of precedence.  Sub-expressions in
+parentheses are evaluated first and may override the precedence
+rules above.
+
+@node Aliases
+@section Aliases
+@cindex alias expansion
+
+@dfn{Aliases} allow a string to be substituted for a word when it is used
+as the first word of a simple command.
+The shell maintains a list of aliases that may be set and unset with
+the @code{alias} and @code{unalias} builtin commands.
+
+The first word of each simple command, if unquoted, is checked to see
+if it has an alias.
+If so, that word is replaced by the text of the alias.
+The characters @samp{/}, @samp{$}, @samp{`}, @samp{=} and any of the
+shell metacharacters or quoting characters listed above may not appear
+in an alias name.
+The replacement text may contain any valid
+shell input, including shell metacharacters.
+The first word of the replacement text is tested for
+aliases, but a word that is identical to an alias being expanded
+is not expanded a second time.
+This means that one may alias @code{ls} to @code{"ls -F"},
+for instance, and Bash does not try to recursively expand the
+replacement text.
+If the last character of the alias value is a
+@code{blank}, then the next command word following the
+alias is also checked for alias expansion.
+
+Aliases are created and listed with the @code{alias}
+command, and removed with the @code{unalias} command.
+
+There is no mechanism for using arguments in the replacement text,
+as in @code{csh}.
+If arguments are needed, use a shell function
+(@pxref{Shell Functions}).
+
+Aliases are not expanded when the shell is not interactive,
+unless the @code{expand_aliases} shell option is set using
+@code{shopt} (@pxref{The Shopt Builtin}).
+
+The rules concerning the definition and use of aliases are
+somewhat confusing. Bash
+always reads at least one complete line of input,
+and all lines that make up a compound command,
+before executing any of the commands on that line or the compound command.
+Aliases are expanded when a
+command is read, not when it is executed.  Therefore, an
+alias definition appearing on the same line as another
+command does not take effect until the next line of input is read.
+The commands following the alias definition
+on that line are not affected by the new alias.
+This behavior is also an issue when functions are executed.
+Aliases are expanded when a function definition is read,
+not when the function is executed, because a function definition
+is itself a command.  As a consequence, aliases
+defined in a function are not available until after that
+function is executed.  To be safe, always put
+alias definitions on a separate line, and do not use @code{alias}
+in compound commands.
+
+For almost every purpose, shell functions are preferred over aliases.
+
+@node Arrays
+@section Arrays
+@cindex arrays
+
+Bash provides one-dimensional indexed and associative array variables.
+Any variable may be used as an indexed array;
+the @code{declare} builtin will explicitly declare an array.
+There is no maximum
+limit on the size of an array, nor any requirement that members
+be indexed or assigned contiguously.
+Indexed arrays are referenced using integers (including arithmetic
+expressions (@pxref{Shell Arithmetic})) and are zero-based;
+associative arrays use arbitrary strings.
+Unless otherwise noted, indexed array indices must be non-negative integers.
+
+An indexed array is created automatically if any variable is assigned to
+using the syntax
+@example
+@var{name}[@var{subscript}]=@var{value}
+@end example
+
+@noindent
+The @var{subscript}
+is treated as an arithmetic expression that must evaluate to a number.
+To explicitly declare an array, use
+@example
+declare -a @var{name}
+@end example
+@noindent
+The syntax
+@example
+declare -a @var{name}[@var{subscript}]
+@end example
+@noindent
+is also accepted; the @var{subscript} is ignored.
+
+@noindent
+Associative arrays are created using
+@example
+declare -A @var{name}
+@end example
+
+Attributes may be
+specified for an array variable using the @code{declare} and
+@code{readonly} builtins.  Each attribute applies to all members of
+an array.
+
+Arrays are assigned to using compound assignments of the form
+@example
+@var{name}=(@var{value1} @var{value2} @dots{} )
+@end example
+@noindent
+where each
+@var{value} may be of the form @code{[@var{subscript}]=}@var{string}.
+Indexed array assignments do not require anything but @var{string}.
+When assigning to indexed arrays, if
+the optional subscript is supplied, that index is assigned to;
+otherwise the index of the element assigned is the last index assigned
+to by the statement plus one.  Indexing starts at zero.
+
+Each @var{value} in the list undergoes all the shell expansions
+described above (@pxref{Shell Expansions}).
+
+When assigning to an associative array, the words in a compound assignment
+may be either assignment statements, for which the subscript is required,
+or a list of words that is interpreted as a sequence of alternating keys
+and values:
+@var{name}=(@var{key1} @var{value1} @var{key2} @var{value2} @dots{} ).
+These are treated identically to
+@var{name}=( [@var{key1}]=@var{value1} [@var{key2}]=@var{value2} @dots{} ).
+The first word in the list determines how the remaining words
+are interpreted; all assignments in a list must be of the same type.
+When using key/value pairs, the keys may not be missing or empty;
+a final missing value is treated like the empty string.
+
+This syntax is also accepted by the @code{declare}
+builtin.  Individual array elements may be assigned to using the
+@code{@var{name}[@var{subscript}]=@var{value}} syntax introduced above.
+
+When assigning to an indexed array, if @var{name}
+is subscripted by a negative number, that number is
+interpreted as relative to one greater than the maximum index of
+@var{name}, so negative indices count back from the end of the
+array, and an index of -1 references the last element.
+
+The @samp{+=} operator will append to an array variable when assigning
+using the compound assignment syntax; see @ref{Shell Parameters} above.
+
+Any element of an array may be referenced using
+@code{$@{@var{name}[@var{subscript}]@}}.
+The braces are required to avoid
+conflicts with the shell's filename expansion operators.  If the
+@var{subscript} is @samp{@@} or @samp{*}, the word expands to all members
+of the array @var{name}.  These subscripts differ only when the word
+appears within double quotes.
+If the word is double-quoted,
+@code{$@{@var{name}[*]@}} expands to a single word with
+the value of each array member separated by the first character of the
+@env{IFS} variable, and @code{$@{@var{name}[@@]@}} expands each element of
+@var{name} to a separate word.  When there are no array members,
+@code{$@{@var{name}[@@]@}} expands to nothing.
+If the double-quoted expansion occurs within a word, the expansion of
+the first parameter is joined with the beginning part of the original
+word, and the expansion of the last parameter is joined with the last
+part of the original word.
+This is analogous to the
+expansion of the special parameters @samp{@@} and @samp{*}. 
+@code{$@{#@var{name}[@var{subscript}]@}} expands to the length of
+@code{$@{@var{name}[@var{subscript}]@}}.
+If @var{subscript} is @samp{@@} or
+@samp{*}, the expansion is the number of elements in the array. 
+If the @var{subscript}
+used to reference an element of an indexed array
+evaluates to a number less than zero, it is
+interpreted as relative to one greater than the maximum index of the array,
+so negative indices count back from the end of the array,
+and an index of -1 refers to the last element.
+
+Referencing an array variable without a subscript is equivalent to
+referencing with a subscript of 0.
+Any reference to a variable using a valid subscript is legal, and
+@code{bash} will create an array if necessary.
+
+An array variable is considered set if a subscript has been assigned a
+value.  The null string is a valid value.
+
+It is possible to obtain the keys (indices) of an array as well as the values.
+$@{!@var{name}[@@]@} and $@{!@var{name}[*]@} expand to the indices
+assigned in array variable @var{name}.
+The treatment when in double quotes is similar to the expansion of the
+special parameters @samp{@@} and @samp{*} within double quotes.
+
+The @code{unset} builtin is used to destroy arrays.
+@code{unset @var{name}[@var{subscript}]}
+destroys the array element at index @var{subscript}.
+Negative subscripts to indexed arrays are interpreted as described above.
+Unsetting the last element of an array variable does not unset the variable.
+@code{unset @var{name}}, where @var{name} is an array, removes the
+entire array.
+@code{unset @var{name}[@var{subscript}]} behaves differently
+depending on the array type when given a
+subscript of @samp{*} or @samp{@@}.
+When @var{name} is an associative array, it removes the element with key
+@samp{*} or @samp{@@}.
+If @var{name} is an indexed array, @code{unset} removes all of the elements,
+but does not remove the array itself.
+
+When using a variable name with a subscript as an argument to a command,
+such as with @code{unset}, without using the word expansion syntax
+described above, the argument is subject to the shell's filename expansion.
+If filename expansion is not desired, the argument should be quoted.
+
+The @code{declare}, @code{local}, and @code{readonly}
+builtins each accept a @option{-a} option to specify an indexed
+array and a @option{-A} option to specify an associative array.
+If both options are supplied, @option{-A} takes precedence.
+The @code{read} builtin accepts a @option{-a}
+option to assign a list of words read from the standard input
+to an array, and can read values from the standard input into
+individual array elements.  The @code{set} and @code{declare}
+builtins display array values in a way that allows them to be
+reused as input.

+
+@menu
+* Directory Stack Builtins::		Bash builtin commands to manipulate
+					the directory stack.
+@end menu
+
+The directory stack is a list of recently-visited directories.  The
+@code{pushd} builtin adds directories to the stack as it changes
+the current directory, and the @code{popd} builtin removes specified
+directories from the stack and changes the current directory to
+the directory removed.  The @code{dirs} builtin displays the contents
+of the directory stack.  The current directory is always the "top"
+of the directory stack.
+
+The contents of the directory stack are also visible
+as the value of the @env{DIRSTACK} shell variable.
+
+@node Directory Stack Builtins
+@subsection Directory Stack Builtins
+
+@table @code
+
+@item dirs
+@btindex dirs
+@example
+dirs [-clpv] [+@var{N} | -@var{N}]
+@end example
+
+Display the list of currently remembered directories.  Directories
+are added to the list with the @code{pushd} command; the
+@code{popd} command removes directories from the list.
+The current directory is always the first directory in the stack.
+
+@table @code
+@item -c
+Clears the directory stack by deleting all of the elements.
+@item -l
+Produces a listing using full pathnames;
+the default listing format uses a tilde to denote the home directory.
+@item -p
+Causes @code{dirs} to print the directory stack with one entry per
+line.
+@item -v
+Causes @code{dirs} to print the directory stack with one entry per
+line, prefixing each entry with its index in the stack.
+@item +@var{N}
+Displays the @var{N}th directory (counting from the left of the
+list printed by @code{dirs} when invoked without options), starting
+with zero.
+@item -@var{N}
+Displays the @var{N}th directory (counting from the right of the
+list printed by @code{dirs} when invoked without options), starting
+with zero.
+@end table
+
+@item popd
+@btindex popd
+@example
+popd [-n] [+@var{N} | -@var{N}]
+@end example
+
+Removes elements from the directory stack.
+The elements are numbered from 0 starting at the first directory
+listed by @code{dirs};
+that is, @code{popd} is equivalent to @code{popd +0}.
+
+When no arguments are given, @code{popd}
+removes the top directory from the stack and changes to
+the new top directory.
+
+Arguments, if supplied, have the following meanings:
+
+@table @code
+@item -n
+Suppresses the normal change of directory when removing directories
+from the stack, so that only the stack is manipulated.
+@item +@var{N}
+Removes the @var{N}th directory (counting from the left of the
+list printed by @code{dirs}), starting with zero, from the stack.
+@item -@var{N}
+Removes the @var{N}th directory (counting from the right of the
+list printed by @code{dirs}), starting with zero, from the stack.
+@end table
+
+If the top element of the directory stack is modified, and
+the @option{-n} option was not supplied, @code{popd} uses the @code{cd}
+builtin to change to the directory at the top of the stack.
+If the @code{cd} fails, @code{popd} returns a non-zero value.
+
+Otherwise, @code{popd} returns an unsuccessful status if
+an invalid option is encountered, the directory stack
+is empty, or a non-existent directory stack entry is specified.
+
+If the @code{popd} command is successful,
+Bash runs @code{dirs} to show the final contents of the directory stack,
+and the return status is 0.
+
+@btindex pushd
+@item pushd
+@example
+pushd [-n] [@var{+N} | @var{-N} | @var{dir}]
+@end example
+
+Adds a directory to the top of the directory stack, or rotates
+the stack, making the new top of the stack the current working
+directory.
+With no arguments, @code{pushd} exchanges the top two elements
+of the directory stack.
+
+Arguments, if supplied, have the following meanings:
+
+@table @code
+@item -n
+Suppresses the normal change of directory when rotating or
+adding directories to the stack, so that only the stack is manipulated.
+@item +@var{N}
+Brings the @var{N}th directory (counting from the left of the
+list printed by @code{dirs}, starting with zero) to the top of
+the list by rotating the stack.
+@item -@var{N}
+Brings the @var{N}th directory (counting from the right of the
+list printed by @code{dirs}, starting with zero) to the top of
+the list by rotating the stack.
+@item @var{dir}
+Makes @var{dir} be the top of the stack.
+@end table
+
+After the stack has been modified, if the @option{-n} option was not
+supplied, @code{pushd} uses the @code{cd} builtin to change to the
+directory at the top of the stack.
+If the @code{cd} fails, @code{pushd} returns a non-zero value.
+
+Otherwise, if no arguments are supplied, @code{pushd} returns 0 unless the
+directory stack is empty.
+When rotating the directory stack, @code{pushd} returns 0 unless
+the directory stack is empty or a non-existent directory stack element
+is specified.
+
+If the @code{pushd} command is successful,
+Bash runs @code{dirs} to show the final contents of the directory stack.

+@cindex prompting
+
+Bash examines the value of the array variable @env{PROMPT_COMMAND} just before
+printing each primary prompt.
+If any elements in  @env{PROMPT_COMMAND} are set and non-null, Bash
+executes each value, in numeric order,
+just as if it had been typed on the command line.
+
+In addition, the following table describes the special characters which

+The date, in "Weekday Month Date" format (e.g., "Tue May 26").
+@item \D@{@var{format}@}
+The @var{format} is passed to @code{strftime}(3) and the result is inserted
+into the prompt string; an empty @var{format} results in a locale-specific
+time representation.  The braces are required.
+@item \e
+An escape character.
+@item \h
+The hostname, up to the first `.'.
+@item \H
+The hostname.
+@item \j
+The number of jobs currently managed by the shell.
+@item \l

+Begin a sequence of non-printing characters.  This could be used to
+embed a terminal control sequence into the prompt.
+@item \]
+End a sequence of non-printing characters.
+@end table
+
+The command number and the history number are usually different:
+the history number of a command is its position in the history
+list, which may include commands restored from the history file
+(@pxref{Bash History Facilities}), while the command number is
+the position in the sequence of commands executed during the current
+shell session.
+
+After the string is decoded, it is expanded via
+parameter expansion, command substitution, arithmetic
+expansion, and quote removal, subject to the value of the
+@code{promptvars} shell option (@pxref{The Shopt Builtin}).
+This can have unwanted side effects if escaped portions of the string
+appear within command substitution or contain characters special to

+
+@node The Restricted Shell
+@section The Restricted Shell
+@cindex restricted shell
+
+If Bash is started with the name @code{rbash}, or the
+@option{--restricted}
+or
+@option{-r}
+option is supplied at invocation, the shell becomes restricted.
+A restricted shell is used to
+set up an environment more controlled than the standard shell.
+A restricted shell behaves identically to @code{bash}
+with the exception that the following are disallowed or not performed:
+
+@itemize @bullet
+@item
+Changing directories with the @code{cd} builtin.
+@item
+Setting or unsetting the values of the @env{SHELL}, @env{PATH},
+@env{HISTFILE},
+@env{ENV}, or @env{BASH_ENV} variables.
+@item
+Specifying command names containing slashes.
+@item
+Specifying a filename containing a slash as an argument to the @code{.}
+builtin command.
+@item
+Specifying a filename containing a slash as an argument to the @code{history}
+builtin command.
+@item
+Specifying a filename containing a slash as an argument to the @option{-p}
+option to the @code{hash} builtin command.
+@item
+Importing function definitions from the shell environment at startup.
+@item
+Parsing the value of @env{SHELLOPTS} from the shell environment at startup.
+@item
+Redirecting output using the @samp{>}, @samp{>|}, @samp{<>}, @samp{>&},
+@samp{&>}, and @samp{>>} redirection operators.
+@item
+Using the @code{exec} builtin to replace the shell with another command.
+@item
+Adding or deleting builtin commands with the
+@option{-f} and @option{-d} options to the @code{enable} builtin.
+@item
+Using the @code{enable} builtin command to enable disabled shell builtins.
+@item
+Specifying the @option{-p} option to the @code{command} builtin.
+@item
+Turning off restricted mode with @samp{set +r} or @samp{shopt -u restricted_shell}.
+@end itemize
+
+These restrictions are enforced after any startup files are read.
+
+When a command that is found to be a shell script is executed
+(@pxref{Shell Scripts}), @code{rbash} turns off any restrictions in
+the shell spawned to execute the script.
+
+The restricted shell mode is only one component of a useful restricted
+environment. It should be accompanied by setting @env{PATH} to a value
+that allows execution of only a few verified commands (commands that
+allow shell escapes are particularly vulnerable), changing the current
+directory to a non-writable directory other than @env{$HOME} after login,
+not allowing the restricted shell to execute shell scripts, and cleaning
+the environment of variables that cause some commands to modify their
+behavior (e.g., @env{VISUAL} or @env{PAGER}).
+
+Modern systems provide more secure ways to implement a restricted environment,
+such as @code{jails}, @code{zones}, or @code{containers}.
+
+
+@node Bash POSIX Mode
+@section Bash POSIX Mode
+@cindex POSIX Mode
+
+Starting Bash with the @option{--posix} command-line option or executing
+@samp{set -o posix} while Bash is running will cause Bash to conform more
+closely to the @sc{posix} standard by changing the behavior to
+match that specified by @sc{posix} in areas where the Bash default differs.
+
+When invoked as @code{sh}, Bash enters @sc{posix} mode after reading the
+startup files.
+
+The following list is what's changed when `@sc{posix} mode' is in effect:
+
+@enumerate
+@item
+Bash ensures that the @env{POSIXLY_CORRECT} variable is set.
+
+@item
+When a command in the hash table no longer exists, Bash will re-search
+@env{$PATH} to find the new location.  This is also available with
+@samp{shopt -s checkhash}.
+
+@item
+Bash will not insert a command without the execute bit set into the
+command hash table, even if it returns it as a (last-ditch) result
+from a @env{$PATH} search.
+
+@item
+The message printed by the job control code and builtins when a job
+exits with a non-zero status is `Done(status)'.
+
+@item
+The message printed by the job control code and builtins when a job
+is stopped is `Stopped(@var{signame})', where @var{signame} is, for
+example, @code{SIGTSTP}.
+
+@item
+Alias expansion is always enabled, even in non-interactive shells.
+
+@item
+Reserved words appearing in a context where reserved words are recognized
+do not undergo alias expansion.
+
+@item
+Alias expansion is performed when initially parsing a command substitution.
+The default mode generally defers it, when enabled, until the command
+substitution is executed. This means that command substitution will not
+expand aliases that are defined after the command substitution is initially
+parsed (e.g., as part of a function definition).
+
+@item
+The @sc{posix} @env{PS1} and @env{PS2} expansions of @samp{!} to
+the history number and @samp{!!} to @samp{!} are enabled,
+and parameter expansion is performed on the values of @env{PS1} and
+@env{PS2} regardless of the setting of the @code{promptvars} option.
+
+@item
+The @sc{posix} startup files are executed (@env{$ENV}) rather than
+the normal Bash files.
+
+@item
+Tilde expansion is only performed on assignments preceding a command
+name, rather than on all assignment statements on the line.
+
+@item
+The default history file is @file{~/.sh_history} (this is the
+default value of @env{$HISTFILE}).
+
+@item
+Redirection operators do not perform filename expansion on the word
+in the redirection unless the shell is interactive.
+
+@item
+Redirection operators do not perform word splitting on the word in the
+redirection.
+
+@item
+Function names must be valid shell @code{name}s.  That is, they may not
+contain characters other than letters, digits, and underscores, and
+may not start with a digit.  Declaring a function with an invalid name
+causes a fatal syntax error in non-interactive shells.
+
+@item
+Function names may not be the same as one of the @sc{posix} special
+builtins.
+
+@item
+@sc{posix} special builtins are found before shell functions
+during command lookup.
+
+@item
+When printing shell function definitions (e.g., by @code{type}), Bash does
+not print the @code{function} keyword.
+
+@item
+Literal tildes that appear as the first character in elements of
+the @env{PATH} variable are not expanded as described above
+under @ref{Tilde Expansion}.
+
+@item
+The @code{time} reserved word may be used by itself as a command.  When
+used in this way, it displays timing statistics for the shell and its
+completed children.  The @env{TIMEFORMAT} variable controls the format
+of the timing information.
+
+@item
+When parsing and expanding a $@{@dots{}@} expansion that appears within
+double quotes, single quotes are no longer special and cannot be used to
+quote a closing brace or other special character, unless the operator is
+one of those defined to perform pattern removal.  In this case, they do
+not have to appear as matched pairs.
+
+@item
+The parser does not recognize @code{time} as a reserved word if the next
+token begins with a @samp{-}.
+
+@ignore
+@item
+When parsing @code{$()} command substitutions containing here-documents,
+the parser does not allow a here-document to be delimited by the closing
+right parenthesis. The newline after the here-document delimiter is required.
+@end ignore
+
+@item
+The @samp{!} character does not introduce history expansion within a
+double-quoted string, even if the @code{histexpand} option is enabled.
+
+@item
+If a @sc{posix} special builtin returns an error status, a
+non-interactive shell exits.  The fatal errors are those listed in
+the @sc{posix} standard, and include things like passing incorrect options,
+redirection errors, variable assignment errors for assignments preceding
+the command name, and so on.
+
+@item
+A non-interactive shell exits with an error status if a variable
+assignment error occurs when no command name follows the assignment
+statements.
+A variable assignment error occurs, for example, when trying to assign
+a value to a readonly variable.
+
+@item
+A non-interactive shell exits with an error status if a variable
+assignment error occurs in an assignment statement preceding a special
+builtin, but not with any other simple command. For any other simple
+command, the shell aborts execution of that command, and execution continues
+at the top level ("the shell shall not perform any further processing of the
+command in which the error occurred").
+
+@item
+A non-interactive shell exits with an error status if the iteration
+variable in a @code{for} statement or the selection variable in a
+@code{select} statement is a readonly variable.
+
+@item
+Non-interactive shells exit if @var{filename} in @code{.} @var{filename}
+is not found.
+
+@item
+Non-interactive shells exit if a syntax error in an arithmetic expansion
+results in an invalid expression.
+
+@item
+Non-interactive shells exit if a parameter expansion error occurs.
+
+@item
+Non-interactive shells exit if there is a syntax error in a script read
+with the @code{.} or @code{source} builtins, or in a string processed by
+the @code{eval} builtin.
+
+@item
+While variable indirection is available, it may not be applied to the
+@samp{#} and @samp{?} special parameters.
+
+@item
+Expanding the @samp{*} special parameter in a pattern context where the
+expansion is double-quoted does not treat the @code{$*} as if it were
+double-quoted.
+
+@item
+Assignment statements preceding @sc{posix} special builtins
+persist in the shell environment after the builtin completes.
+
+@item
+The @code{command} builtin does not prevent builtins that take assignment
+statements as arguments from expanding them as assignment statements;
+when not in @sc{posix} mode, assignment builtins lose their assignment
+statement expansion properties when preceded by @code{command}.
+
+@item
+The @code{bg} builtin uses the required format to describe each job placed
+in the background, which does not include an indication of whether the job
+is the current or previous job.
+
+@item
+The output of @samp{kill -l} prints all the signal names on a single line,
+separated by spaces, without the @samp{SIG} prefix.
+
+@item
+The @code{kill} builtin does not accept signal names with a @samp{SIG}
+prefix.
+
+@item
+The @code{export} and @code{readonly} builtin commands display their
+output in the format required by @sc{posix}.
+
+@item
+The @code{trap} builtin displays signal names without the leading
+@code{SIG}.
+
+@item
+The @code{trap} builtin doesn't check the first argument for a possible
+signal specification and revert the signal handling to the original
+disposition if it is, unless that argument consists solely of digits and
+is a valid signal number.  If users want to reset the handler for a given
+signal to the original disposition, they should use @samp{-} as the
+first argument.
+
+@item
+@code{trap -p} displays signals whose dispositions are set to SIG_DFL and
+those that were ignored when the shell started.
+
+@item
+The @code{.} and @code{source} builtins do not search the current directory
+for the filename argument if it is not found by searching @env{PATH}.
+
+@item
+Enabling @sc{posix} mode has the effect of setting the
+@code{inherit_errexit} option, so
+subshells spawned to execute command substitutions inherit the value of
+the @option{-e} option from the parent shell.
+When the @code{inherit_errexit} option is not enabled,
+Bash clears the @option{-e} option in such subshells.
+
+@item
+Enabling @sc{posix} mode has the effect of setting the
+@code{shift_verbose} option, so numeric arguments to @code{shift}
+that exceed the number of positional parameters will result in an
+error message.
+
+@item
+When the @code{alias} builtin displays alias definitions, it does not
+display them with a leading @samp{alias } unless the @option{-p} option
+is supplied.
+
+@item
+When the @code{set} builtin is invoked without options, it does not display
+shell function names and definitions.
+
+@item
+When the @code{set} builtin is invoked without options, it displays
+variable values without quotes, unless they contain shell metacharacters,
+even if the result contains nonprinting characters.
+
+@item
+When the @code{cd} builtin is invoked in logical mode, and the pathname
+constructed from @code{$PWD} and the directory name supplied as an argument
+does not refer to an existing directory, @code{cd} will fail instead of
+falling back to physical mode.
+
+@item
+When the @code{cd} builtin cannot change a directory because the
+length of the pathname 
+constructed from @code{$PWD} and the directory name supplied as an argument
+exceeds @code{PATH_MAX} when all symbolic links are expanded, @code{cd} will
+fail instead of attempting to use only the supplied directory name.
+
+@item
+The @code{pwd} builtin verifies that the value it prints is the same as the
+current directory, even if it is not asked to check the file system with the
+@option{-P} option.
+
+@item
+When listing the history, the @code{fc} builtin does not include an
+indication of whether or not a history entry has been modified.
+
+@item
+The default editor used by @code{fc} is @code{ed}.
+
+@item
+The @code{type} and @code{command} builtins will not report a non-executable
+file as having been found, though the shell will attempt to execute such a
+file if it is the only so-named file found in @code{$PATH}.
+
+@item
+The @code{vi} editing mode will invoke the @code{vi} editor directly when
+the @samp{v} command is run, instead of checking @code{$VISUAL} and
+@code{$EDITOR}.
+
+@item
+When the @code{xpg_echo} option is enabled, Bash does not attempt to interpret
+any arguments to @code{echo} as options.  Each argument is displayed, after
+escape characters are converted.
+
+@item
+The @code{ulimit} builtin uses a block size of 512 bytes for the @option{-c}
+and @option{-f} options.
+
+@item
+The arrival of @code{SIGCHLD}  when a trap is set on @code{SIGCHLD} does
+not interrupt the @code{wait} builtin and cause it to return immediately.
+The trap command is run once for each child that exits.
+
+@item
+The @code{read} builtin may be interrupted by a signal for which a trap
+has been set.
+If Bash receives a trapped signal while executing @code{read}, the trap
+handler executes and @code{read} returns an exit status greater than 128.
+
+@item
+The @code{printf} builtin uses @code{double} (via @code{strtod}) to convert
+arguments corresponding to floating point conversion specifiers, instead of
+@code{long double} if it's available. The @samp{L} length modifier forces
+@code{printf} to use @code{long double} if it's available.
+
+@item
+Bash removes an exited background process's status from the list of such
+statuses after the @code{wait} builtin is used to obtain it.

+@node Shell Compatibility Mode
+@section Shell Compatibility Mode
+@cindex Compatibility Level
+@cindex Compatibility Mode
+
+Bash-4.0 introduced the concept of a @dfn{shell compatibility level},
+specified as a set of options to the shopt builtin
+(@code{compat31},
+@code{compat32},
+@code{compat40},
+@code{compat41},
+and so on).
+There is only one current
+compatibility level -- each option is mutually exclusive.
+The compatibility level is intended to allow users to select behavior
+from previous versions that is incompatible with newer versions
+while they migrate scripts to use current features and
+behavior. It's intended to be a temporary solution.
+
+This section does not mention behavior that is standard for a particular
+version (e.g., setting @code{compat32} means that quoting the rhs of the regexp
+matching operator quotes special regexp characters in the word, which is
+default behavior in bash-3.2 and subsequent versions). 
+
+If a user enables, say, @code{compat32}, it may affect the behavior of other
+compatibility levels up to and including the current compatibility level.
+The idea is that each compatibility level controls behavior that changed
+in that version of Bash,
+but that behavior may have been present in earlier versions.
+For instance, the change to use locale-based comparisons with the @code{[[}
+command came in bash-4.1, and earlier versions used ASCII-based comparisons,
+so enabling @code{compat32} will enable ASCII-based comparisons as well.
+That granularity may not be sufficient for
+all uses, and as a result users should employ compatibility levels carefully.
+Read the documentation for a particular feature to find out the
+current behavior.
+
+Bash-4.3 introduced a new shell variable: @env{BASH_COMPAT}.
+The value assigned
+to this variable (a decimal version number like 4.2, or an integer
+corresponding to the @code{compat}@var{NN} option, like 42) determines the
+compatibility level.
+
+Starting with bash-4.4, Bash has begun deprecating older compatibility
+levels.
+Eventually, the options will be removed in favor of @env{BASH_COMPAT}.
+
+Bash-5.0 is the final version for which there will be an individual shopt
+option for the previous version. Users should use @env{BASH_COMPAT}
+on bash-5.0 and later versions.
+
+The following table describes the behavior changes controlled by each
+compatibility level setting.
+The @code{compat}@var{NN} tag is used as shorthand for setting the
+compatibility level
+to @var{NN} using one of the following mechanisms.
+For versions prior to bash-5.0, the compatibility level may be set using
+the corresponding @code{compat}@var{NN} shopt option.
+For bash-4.3 and later versions, the @env{BASH_COMPAT} variable is preferred,
+and it is required for bash-5.1 and later versions.

+@node Job Control Basics
+@section Job Control Basics
+@cindex job control
+@cindex foreground
+@cindex background
+@cindex suspending jobs
+
+Job control
+refers to the ability to selectively stop (suspend)
+the execution of processes and continue (resume)
+their execution at a later point.  A user typically employs
+this facility via an interactive interface supplied jointly
+by the operating system kernel's terminal driver and Bash.
+
+The shell associates a @var{job} with each pipeline.  It keeps a
+table of currently executing jobs, which may be listed with the
+@code{jobs} command.  When Bash starts a job
+asynchronously, it prints a line that looks
+like:
+@example
+[1] 25647
+@end example
+@noindent
+indicating that this job is job number 1 and that the process @sc{id}
+of the last process in the pipeline associated with this job is
+25647.  All of the processes in a single pipeline are members of
+the same job.  Bash uses the @var{job} abstraction as the
+basis for job control. 
+
+To facilitate the implementation of the user interface to job
+control, the operating system maintains the notion of a current terminal
+process group @sc{id}.  Members of this process group (processes whose
+process group @sc{id} is equal to the current terminal process group
+@sc{id}) receive keyboard-generated signals such as @code{SIGINT}. 
+These processes are said to be in the foreground.  Background
+processes are those whose process group @sc{id} differs from the
+terminal's; such processes are immune to keyboard-generated
+signals.  Only foreground processes are allowed to read from or, if
+the user so specifies with @code{stty tostop}, write to the terminal.
+Background processes which attempt to
+read from (write to when @code{stty tostop} is in effect) the
+terminal are sent a @code{SIGTTIN} (@code{SIGTTOU})
+signal by the kernel's terminal driver,
+which, unless caught, suspends the process. 
+
+If the operating system on which Bash is running supports
+job control, Bash contains facilities to use it.  Typing the
+@dfn{suspend} character (typically @samp{^Z}, Control-Z) while a
+process is running causes that process to be stopped and returns
+control to Bash.  Typing the @dfn{delayed suspend} character
+(typically @samp{^Y}, Control-Y) causes the process to be stopped
+when it attempts to read input from the terminal, and control to
+be returned to Bash.  The user then manipulates the state of
+this job, using the @code{bg} command to continue it in the
+background, the @code{fg} command to continue it in the
+foreground, or the @code{kill} command to kill it.  A @samp{^Z}
+takes effect immediately, and has the additional side effect of
+causing pending output and typeahead to be discarded. 
+
+There are a number of ways to refer to a job in the shell.  The
+character @samp{%} introduces a job specification (@dfn{jobspec}).
+
+Job number @code{n} may be referred to as @samp{%n}.
+The symbols @samp{%%} and  @samp{%+} refer to the shell's notion of the
+current job, which is the last job stopped while it was in the foreground
+or started in the background.
+A single @samp{%} (with no accompanying job specification) also refers
+to the current job.
+The previous job may be referenced using @samp{%-}.
+If there is only a single job, @samp{%+} and @samp{%-} can both be used
+to refer to that job.
+In output pertaining to jobs (e.g., the output of the @code{jobs}
+command), the current job is always flagged with a @samp{+}, and the
+previous job with a @samp{-}. 
+
+A job may also be referred to
+using a prefix of the name used to start it, or using a substring
+that appears in its command line.  For example, @samp{%ce} refers
+to a stopped job whose command name begins with @samp{ce}.
+Using @samp{%?ce}, on the
+other hand, refers to any job containing the string @samp{ce} in
+its command line.  If the prefix or substring matches more than one job,
+Bash reports an error.
+
+Simply naming a job can be used to bring it into the foreground:
+@samp{%1} is a synonym for @samp{fg %1}, bringing job 1 from the
+background into the foreground.  Similarly, @samp{%1 &} resumes
+job 1 in the background, equivalent to @samp{bg %1}
+
+The shell learns immediately whenever a job changes state. 
+Normally, Bash waits until it is about to print a prompt
+before reporting changes in a job's status so as to not interrupt
+any other output.
+If the @option{-b} option to the @code{set} builtin is enabled,
+Bash reports such changes immediately (@pxref{The Set Builtin}).
+Any trap on @code{SIGCHLD} is executed for each child process
+that exits.
+
+If an attempt to exit Bash is made while jobs are stopped, (or running, if
+the @code{checkjobs} option is enabled -- see @ref{The Shopt Builtin}), the
+shell prints a warning message, and if the @code{checkjobs} option is
+enabled, lists the jobs and their statuses.
+The @code{jobs} command may then be used to inspect their status.
+If a second attempt to exit is made without an intervening command,
+Bash does not print another warning, and any stopped jobs are terminated.
+
+When the shell is waiting for a job or process using the @code{wait}
+builtin, and job control is enabled, @code{wait} will return when the
+job changes state. The @option{-f} option causes @code{wait} to wait
+until the job or process terminates before returning.
+

+@section Job Control Builtins
+
+@table @code
+
+@item bg
+@btindex bg
+@example
+bg [@var{jobspec} @dots{}]
+@end example
+
+Resume each suspended job @var{jobspec} in the background, as if it
+had been started with @samp{&}.
+If @var{jobspec} is not supplied, the current job is used.
+The return status is zero unless it is run when job control is not
+enabled, or, when run with job control enabled, any
+@var{jobspec} was not found or specifies a job
+that was started without job control.
+
+@item fg
+@btindex fg
+@example
+fg [@var{jobspec}]
+@end example
+
+Resume the job @var{jobspec} in the foreground and make it the current job.
+If @var{jobspec} is not supplied, the current job is used.
+The return status is that of the command placed into the foreground,
+or non-zero if run when job control is disabled or, when run with
+job control enabled, @var{jobspec} does not specify a valid job or
+@var{jobspec} specifies a job that was started without job control.
+
+@item jobs
+@btindex jobs
+@example
+jobs [-lnprs] [@var{jobspec}]
+jobs -x @var{command} [@var{arguments}]
+@end example
+
+The first form lists the active jobs.  The options have the
+following meanings:
+
+@table @code
+@item -l
+List process @sc{id}s in addition to the normal information.
+
+@item -n
+Display information only about jobs that have changed status since
+the user was last notified of their status.
+
+@item -p
+List only the process @sc{id} of the job's process group leader.
+
+@item -r
+Display only running jobs.
+
+@item -s
+Display only stopped jobs.
+@end table
+
+If @var{jobspec} is given,
+output is restricted to information about that job. 
+If @var{jobspec} is not supplied, the status of all jobs is
+listed.
+
+If the @option{-x} option is supplied, @code{jobs} replaces any
+@var{jobspec} found in @var{command} or @var{arguments} with the
+corresponding process group @sc{id}, and executes @var{command},
+passing it @var{argument}s, returning its exit status. 
+
+@item kill
+@btindex kill
+@example
+kill [-s @var{sigspec}] [-n @var{signum}] [-@var{sigspec}] @var{jobspec} or @var{pid}
+kill -l|-L [@var{exit_status}]
+@end example
+
+Send a signal specified by @var{sigspec} or @var{signum} to the process
+named by job specification @var{jobspec} or process @sc{id} @var{pid}.
+@var{sigspec} is either a case-insensitive signal name such as
+@code{SIGINT} (with or without the @code{SIG} prefix)
+or a signal number; @var{signum} is a signal number.
+If @var{sigspec} and @var{signum} are not present, @code{SIGTERM} is used.
+The @option{-l} option lists the signal names.
+If any arguments are supplied when @option{-l} is given, the names of the
+signals corresponding to the arguments are listed, and the return status
+is zero.
+@var{exit_status} is a number specifying a signal number or the exit
+status of a process terminated by a signal.
+The @option{-L} option is equivalent to @option{-l}.
+The return status is zero if at least one signal was successfully sent,
+or non-zero if an error occurs or an invalid option is encountered.
+
+@item wait
+@btindex wait
+@example
+wait [-fn] [-p @var{varname}] [@var{jobspec} or @var{pid} @dots{}]
+@end example
+
+Wait until the child process specified by each process @sc{id} @var{pid}
+or job specification @var{jobspec} exits and return the exit status of the
+last command waited for.
+If a job spec is given, all processes in the job are waited for.
+If no arguments are given,
+@code{wait} waits for all running background jobs and
+the last-executed process substitution, if its process id is the same as
+@var{$!},
+and the return status is zero.
+If the @option{-n} option is supplied, @code{wait} waits for a single job
+from the list of @var{pid}s or @var{jobspec}s or, if no arguments are
+supplied, any job, 
+to complete and returns its exit status.
+If none of the supplied arguments is a child of the shell, or if no arguments
+are supplied and the shell has no unwaited-for children, the exit status
+is 127.
+If the @option{-p} option is supplied, the process or job identifier of the job
+for which the exit status is returned is assigned to the variable
+@var{varname} named by the option argument.
+The variable will be unset initially, before any assignment.
+This is useful only when the @option{-n} option is supplied.
+Supplying the @option{-f} option, when job control is enabled,
+forces @code{wait} to wait for each @var{pid} or @var{jobspec} to
+terminate before returning its status, instead of returning when it changes
+status.
+If neither @var{jobspec} nor @var{pid} specifies an active child process
+of the shell, the return status is 127.
+If @code{wait} is interrupted by a signal, the return status will be greater
+than 128, as described above (@pxref{Signals}).
+Otherwise, the return status is the exit  status
+of the last process or job waited for.
+
+@item disown
+@btindex disown
+@example
+disown [-ar] [-h] [@var{jobspec} @dots{} | @var{pid} @dots{} ]
+@end example
+
+Without options, remove each @var{jobspec} from the table of
+active jobs.
+If the @option{-h} option is given, the job is not removed from the table,
+but is marked so that @code{SIGHUP} is not sent to the job if the shell
+receives a @code{SIGHUP}.
+If @var{jobspec} is not present, and neither the @option{-a} nor the
+@option{-r} option is supplied, the current job is used.
+If no @var{jobspec} is supplied, the @option{-a} option means to remove or
+mark all jobs; the @option{-r} option without a @var{jobspec}
+argument restricts operation to running jobs.
+
+@item suspend
+@btindex suspend
+@example
+suspend [-f]
+@end example
+
+Suspend the execution of this shell until it receives a
+@code{SIGCONT} signal.
+A login shell,
+or a shell without job control enabled,
+cannot be suspended; the @option{-f}
+option can be used to override this and force the suspension.
+The return status is 0 unless the shell is a login shell
+or job control is not enabled
+and
+@option{-f}
+is not supplied.
+
+@end table
+
+When job control is not active, the @code{kill} and @code{wait}
+builtins do not accept @var{jobspec} arguments.  They must be
+supplied process @sc{id}s.

+@vtable @code
+
+@item auto_resume
+This variable controls how the shell interacts with the user and

+more than one job beginning with the string typed, then
+the most recently accessed job will be selected.
+The name of a stopped job, in this context, is the command line
+used to start it.  If this variable is set to the value @samp{exact},
+the string supplied must match the name of a stopped job exactly;
+if set to @samp{substring},
+the string supplied needs to match a substring of the name of a

+@cindex Bash configuration
+
+These are installation instructions for Bash.
+
+The simplest way to compile Bash is:
+
+@enumerate
+@item
+@code{cd} to the directory containing the source code and type
+@samp{./configure} to configure Bash for your system.  If you're
+using @code{csh} on an old version of System V, you might need to
+type @samp{sh ./configure} instead to prevent @code{csh} from trying
+to execute @code{configure} itself.
+
+Running @code{configure} takes some time.
+While running, it prints messages telling which features it is
+checking for.
+
+@item
+Type @samp{make} to compile Bash and build the @code{bashbug} bug
+reporting script.
+
+@item
+Optionally, type @samp{make tests} to run the Bash test suite.
+
+@item
+Type @samp{make install} to install @code{bash} and @code{bashbug}.
+This will also install the manual pages and Info file, message translation
+files, some supplemental documentation, a number of example loadable
+builtin commands, and a set of header files for developing loadable
+builtins.
+You may need additional privileges to install @code{bash} to your
+desired destination, so @samp{sudo make install} might be required.
+More information about controlling the locations where @code{bash} and
+other files are installed is below (@pxref{Installation Names}).
+
+@end enumerate
+
+The @code{configure} shell script attempts to guess correct
+values for various system-dependent variables used during
+compilation.  It uses those values to create a @file{Makefile} in
+each directory of the package (the top directory, the
+@file{builtins}, @file{doc}, @file{po}, and @file{support} directories,
+each directory under @file{lib}, and several others).  It also creates a
+@file{config.h} file containing system-dependent definitions. 
+Finally, it creates a shell script named @code{config.status} that you
+can run in the future to recreate the current configuration, a
+file @file{config.cache} that saves the results of its tests to
+speed up reconfiguring, and a file @file{config.log} containing
+compiler output (useful mainly for debugging @code{configure}). 
+If at some point
+@file{config.cache} contains results you don't want to keep, you
+may remove or edit it. 
+
+To find out more about the options and arguments that the
+@code{configure} script understands, type 
+
+@example
+bash-4.2$ ./configure --help
+@end example
+
+@noindent
+at the Bash prompt in your Bash source directory.
+
+If you want to build Bash in a directory separate from the source
+directory -- to build for multiple architectures, for example --
+just use the full path to the configure script. The following commands
+will build bash in a directory under @file{/usr/local/build} from
+the source code in @file{/usr/local/src/bash-4.4}:
+
+@example
+mkdir /usr/local/build/bash-4.4
+cd /usr/local/build/bash-4.4
+bash /usr/local/src/bash-4.4/configure
+make
+@end example
+
+See @ref{Compiling For Multiple Architectures} for more information
+about building in a directory separate from the source.

+If you need to do unusual things to compile Bash, please
+try to figure out how @code{configure} could check whether or not
+to do them, and mail diffs or instructions to
+@email{bash-maintainers@@gnu.org} so they can be
+considered for the next release.
+
+The file @file{configure.ac} is used to create @code{configure}
+by a program called Autoconf.
+You only need @file{configure.ac} if you want to change it or regenerate
+@code{configure} using a newer version of Autoconf.
+If you do this, make sure you are using Autoconf version 2.69 or
+newer.
+
+You can remove the program binaries and object files from the
+source code directory by typing @samp{make clean}.  To also remove the
+files that @code{configure} created (so you can compile Bash for
+a different kind of computer), type @samp{make distclean}.
+
+@node Compilers and Options
+@section Compilers and Options
+
+Some systems require unusual options for compilation or linking
+that the @code{configure} script does not know about.  You can
+give @code{configure} initial values for variables by setting
+them in the environment.  Using a Bourne-compatible shell, you
+can do that on the command line like this:
+
+@example
+CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+@end example
+
+On systems that have the @code{env} program, you can do it like this:
+
+@example
+env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+@end example
+
+The configuration process uses GCC to build Bash if it
+is available.
+
+@node Compiling For Multiple Architectures
+@section Compiling For Multiple Architectures
+
+You can compile Bash for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of @code{make} that
+supports the @code{VPATH} variable, such as GNU @code{make}.
+@code{cd} to the
+directory where you want the object files and executables to go and run
+the @code{configure} script from the source directory
+(@pxref{Basic Installation}).
+You may need to
+supply the @option{--srcdir=PATH} argument to tell @code{configure} where the
+source files are.  @code{configure} automatically checks for the
+source code in the directory that @code{configure} is in and in `..'.
+
+If you have to use a @code{make} that does not support the @code{VPATH}
+variable, you can compile Bash for one architecture at a
+time in the source code directory.  After you have installed
+Bash for one architecture, use @samp{make distclean} before
+reconfiguring for another architecture.
+
+Alternatively, if your system supports symbolic links, you can use the
+@file{support/mkclone} script to create a build tree which has
+symbolic links back to each file in the source directory.  Here's an
+example that creates a build directory in the current directory from a
+source directory @file{/usr/gnu/src/bash-2.0}:
+
+@example
+bash /usr/gnu/src/bash-2.0/support/mkclone -s /usr/gnu/src/bash-2.0 .
+@end example
+
+@noindent
+The @code{mkclone} script requires Bash, so you must have already built
+Bash for at least one architecture before you can create build
+directories for other architectures.
+
+@node Installation Names
+@section Installation Names
+
+By default, @samp{make install} will install into
+@file{/usr/local/bin}, @file{/usr/local/man}, etc.;
+that is, the @dfn{installation prefix} defaults to @file{/usr/local}.
+You can specify an installation prefix other than @file{/usr/local} by
+giving @code{configure} the option @option{--prefix=@var{PATH}},
+or by specifying a value for the @env{prefix} @samp{make}
+variable when running @samp{make install}
+(e.g., @samp{make install prefix=@var{PATH}}).
+The @env{prefix} variable provides a default for @env{exec_prefix} and
+other variables used when installing bash.
+
+You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. 
+If you give @code{configure} the option
+@option{--exec-prefix=@var{PATH}}, @samp{make install} will use
+@var{PATH} as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+If you would like to change the installation locations for a single run,
+you can specify these variables as arguments to @code{make}:
+@samp{make install exec_prefix=/} will install @code{bash} and
+@code{bashbug} into @file{/bin} instead of the default @file{/usr/local/bin}.
+
+If you want to see the files bash will install and where it will install
+them without changing anything on your system, specify the variable
+@env{DESTDIR} as an argument to @code{make}. Its value should be the
+absolute directory path you'd like to use as the root of your sample
+installation tree. For example,
+
+@example
+mkdir /fs1/bash-install
+make install DESTDIR=/fs1/bash-install
+@end example
+
+@noindent
+will install @code{bash} into @file{/fs1/bash-install/usr/local/bin/bash},
+the documentation into directories within
+@file{/fs1/bash-install/usr/local/share}, the example loadable builtins into
+@file{/fs1/bash-install/usr/local/lib/bash}, and so on.
+You can use the usual @env{exec_prefix} and @env{prefix} variables to alter
+the directory paths beneath the value of @env{DESTDIR}.
+
+The GNU Makefile standards provide a more complete description of these
+variables and their effects.
+
+@node Specifying the System Type
+@section Specifying the System Type
+
+There may be some features @code{configure} can not figure out
+automatically, but needs to determine by the type of host Bash
+will run on.  Usually @code{configure} can figure that
+out, but if it prints a message saying it can not guess the host
+type, give it the @option{--host=TYPE} option.  @samp{TYPE} can
+either be a short name for the system type, such as @samp{sun4},
+or a canonical name with three fields: @samp{CPU-COMPANY-SYSTEM}
+(e.g., @samp{i386-unknown-freebsd4.2}).
+
+See the file @file{support/config.sub} for the possible
+values of each field. 
+
+@node Sharing Defaults
+@section Sharing Defaults
+
+If you want to set default values for @code{configure} scripts to
+share, you can create a site shell script called
+@code{config.site} that gives default values for variables like
+@code{CC}, @code{cache_file}, and @code{prefix}.  @code{configure}
+looks for @file{PREFIX/share/config.site} if it exists, then
+@file{PREFIX/etc/config.site} if it exists.  Or, you can set the
+@code{CONFIG_SITE} environment variable to the location of the site
+script.  A warning: the Bash @code{configure} looks for a site script,
+but not all @code{configure} scripts do.
+
+@node Operation Controls
+@section Operation Controls
+
+@code{configure} recognizes the following options to control how it
+operates.
+
+@table @code
+
+@item --cache-file=@var{file}
+Use and save the results of the tests in
+@var{file} instead of @file{./config.cache}.  Set @var{file} to
+@file{/dev/null} to disable caching, for debugging
+@code{configure}. 
+
+@item --help
+Print a summary of the options to @code{configure}, and exit.
+
+@item --quiet
+@itemx --silent
+@itemx -q
+Do not print messages saying which checks are being made.
+
+@item --srcdir=@var{dir}
+Look for the Bash source code in directory @var{dir}.  Usually
+@code{configure} can determine that directory automatically.
+
+@item --version
+Print the version of Autoconf used to generate the @code{configure}
+script, and exit.
+@end table
+
+@code{configure} also accepts some other, not widely used, boilerplate
+options.  @samp{configure --help} prints the complete list.
+
+@node Optional Features
+@section Optional Features
+
+The Bash @code{configure} has a number of @option{--enable-@var{feature}}
+options, where @var{feature} indicates an optional part of Bash.
+There are also several @option{--with-@var{package}} options,
+where @var{package} is something like @samp{bash-malloc} or @samp{purify}.
+To turn off the default use of a package, use
+@option{--without-@var{package}}.  To configure Bash without a feature
+that is enabled by default, use @option{--disable-@var{feature}}.
+
+Here is a complete list of the @option{--enable-} and
+@option{--with-} options that the Bash @code{configure} recognizes. 
+
+@table @code
+@item --with-afs
+Define if you are using the Andrew File System from Transarc.
+
+@item --with-bash-malloc
+Use the Bash version of
+@code{malloc} in the directory @file{lib/malloc}.  This is not the same
+@code{malloc} that appears in @sc{gnu} libc, but an older version
+originally derived from the 4.2 @sc{bsd} @code{malloc}.  This @code{malloc}
+is very fast, but wastes some space on each allocation.
+This option is enabled by default.
+The @file{NOTES} file contains a list of systems for
+which this should be turned off, and @code{configure} disables this
+option automatically for a number of systems.
+
+@item --with-curses
+Use the curses library instead of the termcap library.  This should
+be supplied if your system has an inadequate or incomplete termcap
+database.
+
+@item --with-gnu-malloc
+A synonym for @code{--with-bash-malloc}.
+
+@item --with-installed-readline[=@var{PREFIX}]
+Define this to make Bash link with a locally-installed version of Readline
+rather than the version in @file{lib/readline}.  This works only with
+Readline 5.0 and later versions.  If @var{PREFIX} is @code{yes} or not
+supplied, @code{configure} uses the values of the make variables
+@code{includedir} and @code{libdir}, which are subdirectories of @code{prefix}
+by default, to find the installed version of Readline if it is not in
+the standard system include and library directories.
+If @var{PREFIX} is @code{no}, Bash links with the version in
+@file{lib/readline}.
+If @var{PREFIX} is set to any other value, @code{configure} treats it as
+a directory pathname and looks for
+the installed version of Readline in subdirectories of that directory
+(include files in @var{PREFIX}/@code{include} and the library in
+@var{PREFIX}/@code{lib}).
+
+@item --with-libintl-prefix[=@var{PREFIX}]
+Define this to make Bash link with a locally-installed version of the
+libintl library instead of the version in @file{lib/intl}.
+
+@item --with-libiconv-prefix[=@var{PREFIX}]
+Define this to make Bash look for libiconv in @var{PREFIX} instead of the
+standard system locations. There is no version included with Bash.
+
+@item --enable-minimal-config
+This produces a shell with minimal features, close to the historical
+Bourne shell.
+@end table
+
+There are several @option{--enable-} options that alter how Bash is
+compiled, linked, and installed, rather than changing run-time features.
+
+@table @code
+@item --enable-largefile
+Enable support for @uref{http://www.unix.org/version2/whatsnew/lfs20mar.html,
+large files} if the operating system requires special compiler options
+to build programs which can access large files.  This is enabled by
+default, if the operating system provides large file support.
+
+@item --enable-profiling
+This builds a Bash binary that produces profiling information to be
+processed by @code{gprof} each time it is executed.
+
+@item --enable-separate-helpfiles
+Use external files for the documentation displayed by the @code{help} builtin
+instead of storing the text internally.
+
+@item --enable-static-link
+This causes Bash to be linked statically, if @code{gcc} is being used.
+This could be used to build a version to use as root's shell.
+
+@end table
+
+The @samp{minimal-config} option can be used to disable all of
+the following options, but it is processed first, so individual
+options may be enabled using @samp{enable-@var{feature}}. 
+
+All of the following options except for
+@samp{alt-array-implementation},
+@samp{disabled-builtins},
+@samp{direxpand-default},
+@samp{strict-posix-default},
+and
+@samp{xpg-echo-default} are
+enabled by default, unless the operating system does not provide the
+necessary support.
+
+@table @code
+@item --enable-alias
+Allow alias expansion and include the @code{alias} and @code{unalias}
+builtins (@pxref{Aliases}).
+
+@item --enable-alt-array-implementation
+This builds bash using an alternate implementation of arrays
+(@pxref{Arrays}) that provides faster access at the expense of using
+more memory (sometimes many times more, depending on how sparse an array is).
+
+@item --enable-arith-for-command
+Include support for the alternate form of the @code{for} command
+that behaves like the C language @code{for} statement
+(@pxref{Looping Constructs}).
+
+@item --enable-array-variables
+Include support for one-dimensional array shell variables
+(@pxref{Arrays}).
+
+@item --enable-bang-history
+Include support for @code{csh}-like history substitution
+(@pxref{History Interaction}).
+
+@item --enable-brace-expansion
+Include @code{csh}-like brace expansion
+( @code{b@{a,b@}c} @expansion{} @code{bac bbc} ).
+See @ref{Brace Expansion}, for a complete description.
+
+@item --enable-casemod-attributes
+Include support for case-modifying attributes in the @code{declare} builtin
+and assignment statements.  Variables with the @code{uppercase} attribute,
+for example, will have their values converted to uppercase upon assignment.
+
+@item --enable-casemod-expansion
+Include support for case-modifying word expansions.
+
+@item --enable-command-timing
+Include support for recognizing @code{time} as a reserved word and for
+displaying timing statistics for the pipeline following @code{time}
+(@pxref{Pipelines}).
+This allows pipelines as well as shell builtins and functions to be timed.
+
+@item --enable-cond-command
+Include support for the @code{[[} conditional command.
+(@pxref{Conditional Constructs}).
+
+@item --enable-cond-regexp
+Include support for matching @sc{posix} regular expressions using the
+@samp{=~} binary operator in the @code{[[} conditional command.
+(@pxref{Conditional Constructs}).
+
+@item --enable-coprocesses
+Include support for coprocesses and the @code{coproc} reserved word
+(@pxref{Pipelines}).
+
+@item --enable-debugger
+Include support for the bash debugger (distributed separately).
+
+@item --enable-dev-fd-stat-broken
+If calling @code{stat} on /dev/fd/@var{N} returns different results than
+calling @code{fstat} on file descriptor @var{N}, supply this option to
+enable a workaround.
+This has implications for conditional commands that test file attributes.
+
+@item --enable-direxpand-default
+Cause the @code{direxpand} shell option (@pxref{The Shopt Builtin})
+to be enabled by default when the shell starts.
+It is normally disabled by default.
+
+@item --enable-directory-stack
+Include support for a @code{csh}-like directory stack and the
+@code{pushd}, @code{popd}, and @code{dirs} builtins
+(@pxref{The Directory Stack}).
+
+@item --enable-disabled-builtins
+Allow builtin commands to be invoked via @samp{builtin xxx}
+even after @code{xxx} has been disabled using @samp{enable -n xxx}.
+See @ref{Bash Builtins}, for details of the @code{builtin} and
+@code{enable} builtin commands.
+
+@item --enable-dparen-arithmetic
+Include support for the @code{((@dots{}))} command
+(@pxref{Conditional Constructs}).
+
+@item --enable-extended-glob
+Include support for the extended pattern matching features described
+above under @ref{Pattern Matching}.
+
+@item --enable-extended-glob-default
+Set the default value of the @code{extglob} shell option described
+above under @ref{The Shopt Builtin} to be enabled.
+
+@item --enable-function-import
+Include support for importing function definitions exported by another
+instance of the shell from the environment.  This option is enabled by
+default.
+
+@item --enable-glob-asciirange-default
+Set the default value of the @code{globasciiranges} shell option described
+above under @ref{The Shopt Builtin} to be enabled.
+This controls the behavior of character ranges when used in pattern matching
+bracket expressions.
+
+@item --enable-help-builtin
+Include the @code{help} builtin, which displays help on shell builtins and
+variables (@pxref{Bash Builtins}).
+
+@item --enable-history
+Include command history and the @code{fc} and @code{history}
+builtin commands (@pxref{Bash History Facilities}).
+
+@item --enable-job-control
+This enables the job control features (@pxref{Job Control}),
+if the operating system supports them.
+
+@item --enable-multibyte
+This enables support for multibyte characters if the operating
+system provides the necessary support.
+
+@item --enable-net-redirections
+This enables the special handling of filenames of the form
+@code{/dev/tcp/@var{host}/@var{port}} and
+@code{/dev/udp/@var{host}/@var{port}}
+when used in redirections (@pxref{Redirections}).
+
+@item --enable-process-substitution
+This enables process substitution (@pxref{Process Substitution}) if
+the operating system provides the necessary support.
+
+@item --enable-progcomp
+Enable the programmable completion facilities
+(@pxref{Programmable Completion}).
+If Readline is not enabled, this option has no effect.
+
+@item --enable-prompt-string-decoding
+Turn on the interpretation of a number of backslash-escaped characters
+in the @env{$PS0}, @env{$PS1}, @env{$PS2}, and @env{$PS4} prompt
+strings.  See @ref{Controlling the Prompt}, for a complete list of prompt
+string escape sequences.
+
+@item --enable-readline
+Include support for command-line editing and history with the Bash
+version of the Readline library (@pxref{Command Line Editing}).
+
+@item --enable-restricted
+Include support for a @dfn{restricted shell}.  If this is enabled, Bash,
+when called as @code{rbash}, enters a restricted mode.  See
+@ref{The Restricted Shell}, for a description of restricted mode.
+
+@item --enable-select
+Include the @code{select} compound command, which allows the generation of
+simple menus (@pxref{Conditional Constructs}).
+
+@item --enable-single-help-strings
+Store the text displayed by the @code{help} builtin as a single string for
+each help topic.  This aids in translating the text to different languages.
+You may need to disable this if your compiler cannot handle very long string
+literals.
+
+@item --enable-strict-posix-default
+Make Bash @sc{posix}-conformant by default (@pxref{Bash POSIX Mode}).

+
+@item --enable-xpg-echo-default
+Make the @code{echo} builtin expand backslash-escaped characters by default,
+without requiring the @option{-e} option.
+This sets the default value of the @code{xpg_echo} shell option to @code{on},
+which makes the Bash @code{echo} behave more like the version specified in
+the Single Unix Specification, version 3.

+@node Major Differences From The Bourne Shell
+@appendix Major Differences From The Bourne Shell
+
+Bash implements essentially the same grammar, parameter and
+variable expansion, redirection, and quoting as the Bourne Shell. 
+Bash uses the @sc{posix} standard as the specification of
+how these features are to be implemented.  There are some
+differences between the traditional Bourne shell and Bash; this
+section quickly details the differences of significance.  A
+number of these differences are explained in greater depth in
+previous sections.
+This section uses the version of @code{sh} included in SVR4.2 (the
+last version of the historical Bourne shell) as the baseline reference.
+
+@itemize @bullet
+
+@item
+Bash is @sc{posix}-conformant, even where the @sc{posix} specification
+differs from traditional @code{sh} behavior (@pxref{Bash POSIX Mode}).
+
+@item
+Bash has multi-character invocation options (@pxref{Invoking Bash}).
+
+@item
+Bash has command-line editing (@pxref{Command Line Editing}) and
+the @code{bind} builtin.
+
+@item
+Bash provides a programmable word completion mechanism
+(@pxref{Programmable Completion}), and builtin commands
+@code{complete}, @code{compgen}, and @code{compopt}, to
+manipulate it.
+
+@item
+Bash has command history (@pxref{Bash History Facilities}) and the
+@code{history} and @code{fc} builtins to manipulate it.
+The Bash history list maintains timestamp information and uses the
+value of the @code{HISTTIMEFORMAT} variable to display it.
+
+@item
+Bash implements @code{csh}-like history expansion
+(@pxref{History Interaction}).
+
+@item
+Bash has one-dimensional array variables (@pxref{Arrays}), and the
+appropriate variable expansions and assignment syntax to use them.
+Several of the Bash builtins take options to act on arrays.
+Bash provides a number of built-in array variables.
+
+@item
+The @code{$'@dots{}'} quoting syntax, which expands ANSI-C
+backslash-escaped characters in the text between the single quotes,
+is supported (@pxref{ANSI-C Quoting}).
+
+@item
+Bash supports the @code{$"@dots{}"} quoting syntax to do
+locale-specific translation of the characters between the double
+quotes.  The @option{-D}, @option{--dump-strings}, and @option{--dump-po-strings}
+invocation options list the translatable strings found in a script
+(@pxref{Locale Translation}).
+
+@item
+Bash implements the @code{!} keyword to negate the return value of
+a pipeline (@pxref{Pipelines}).
+Very useful when an @code{if} statement needs to act only if a test fails.
+The Bash @samp{-o pipefail} option to @code{set} will cause a pipeline to
+return a failure status if any command fails.
+
+@item
+Bash has the @code{time} reserved word and command timing (@pxref{Pipelines}).
+The display of the timing statistics may be controlled with the
+@env{TIMEFORMAT} variable.
+
+@item
+Bash implements the @code{for (( @var{expr1} ; @var{expr2} ; @var{expr3} ))}
+arithmetic for command, similar to the C language (@pxref{Looping Constructs}).
+
+@item
+Bash includes the @code{select} compound command, which allows the
+generation of simple menus (@pxref{Conditional Constructs}).
+
+@item
+Bash includes the @code{[[} compound command, which makes conditional
+testing part of the shell grammar (@pxref{Conditional Constructs}), including
+optional regular expression matching.
+
+@item
+Bash provides optional case-insensitive matching for the @code{case} and
+@code{[[} constructs.
+
+@item
+Bash includes brace expansion (@pxref{Brace Expansion}) and tilde
+expansion (@pxref{Tilde Expansion}).
+
+@item
+Bash implements command aliases and the @code{alias} and @code{unalias}
+builtins (@pxref{Aliases}).
+
+@item
+Bash provides shell arithmetic, the @code{((} compound command
+(@pxref{Conditional Constructs}),
+and arithmetic expansion (@pxref{Shell Arithmetic}).
+
+@item
+Variables present in the shell's initial environment are automatically
+exported to child processes.  The Bourne shell does not normally do
+this unless the variables are explicitly marked using the @code{export}
+command.
+
+@item
+Bash supports the @samp{+=} assignment operator, which appends to the value
+of the variable named on the left hand side.
+
+@item
+Bash includes the @sc{posix} pattern removal @samp{%}, @samp{#}, @samp{%%}
+and @samp{##} expansions to remove leading or trailing substrings from
+variable values (@pxref{Shell Parameter Expansion}).
+
+@item
+The expansion @code{$@{#xx@}}, which returns the length of @code{$@{xx@}},
+is supported (@pxref{Shell Parameter Expansion}).
+
+@item
+The expansion @code{$@{var:}@var{offset}@code{[:}@var{length}@code{]@}},
+which expands to the substring of @code{var}'s value of length
+@var{length}, beginning at @var{offset}, is present
+(@pxref{Shell Parameter Expansion}).
+
+@item
+The expansion
+@code{$@{@var{var}/[/]}@var{pattern}@code{[/}@var{replacement}@code{]@}},
+which matches @var{pattern} and replaces it with @var{replacement} in
+the value of @var{var}, is available (@pxref{Shell Parameter Expansion}).
+
+@item
+The expansion @code{$@{!@var{prefix}*@}} expansion, which expands to
+the names of all shell variables whose names begin with @var{prefix},
+is available (@pxref{Shell Parameter Expansion}).
+
+@item
+Bash has indirect variable expansion using @code{$@{!word@}}
+(@pxref{Shell Parameter Expansion}).
+
+@item
+Bash can expand positional parameters beyond @code{$9} using
+@code{$@{@var{num}@}}.
+
+@item
+The @sc{posix} @code{$()} form of command substitution
+is implemented (@pxref{Command Substitution}),
+and preferred to the Bourne shell's @code{``} (which
+is also implemented for backwards compatibility).
+
+@item
+Bash has process substitution (@pxref{Process Substitution}).
+
+@item
+Bash automatically assigns variables that provide information about the
+current user (@env{UID}, @env{EUID}, and @env{GROUPS}), the current host

+and the instance of Bash that is running (@env{BASH},
+@env{BASH_VERSION}, and @env{BASH_VERSINFO}).  @xref{Bash Variables},
+for details.
+
+@item
+The @env{IFS} variable is used to split only the results of expansion,
+not all words (@pxref{Word Splitting}).
+This closes a longstanding shell security hole.
+
+@item
+The filename expansion bracket expression code uses @samp{!} and @samp{^}
+to negate the set of characters between the brackets.
+The Bourne shell uses only @samp{!}.
+
+@item
+Bash implements the full set of @sc{posix} filename expansion operators,
+including character classes, equivalence classes, and
+collating symbols (@pxref{Filename Expansion}).
+
+@item
+Bash implements extended pattern matching features when the @code{extglob}
+shell option is enabled (@pxref{Pattern Matching}).
+
+@item
+It is possible to have a variable and a function with the same name;
+@code{sh} does not separate the two name spaces.
+
+@item
+Bash functions are permitted to have local variables using the
+@code{local} builtin, and thus useful recursive functions may be written
+(@pxref{Bash Builtins}).
+
+@item
+Variable assignments preceding commands affect only that command, even
+builtins and functions (@pxref{Environment}).
+In @code{sh}, all variable assignments 
+preceding commands are global unless the command is executed from the
+file system.
+
+@item
+Bash performs filename expansion on filenames specified as operands
+to input and output redirection operators (@pxref{Redirections}).
+
+@item
+Bash contains the @samp{<>} redirection operator, allowing a file to be
+opened for both reading and writing, and the @samp{&>} redirection
+operator, for directing standard output and standard error to the same
+file (@pxref{Redirections}).
+
+@item
+Bash includes the @samp{<<<} redirection operator, allowing a string to
+be used as the standard input to a command.
+
+@item
+Bash implements the @samp{[n]<&@var{word}} and @samp{[n]>&@var{word}}
+redirection operators, which move one file descriptor to another.
+
+@item
+Bash treats a number of filenames specially when they are
+used in redirection operators (@pxref{Redirections}).
+
+@item
+Bash can open network connections to arbitrary machines and services
+with the redirection operators (@pxref{Redirections}).
+
+@item
+The @code{noclobber} option is available to avoid overwriting existing
+files with output redirection (@pxref{The Set Builtin}).
+The @samp{>|} redirection operator may be used to override @code{noclobber}.
+
+@item
+The Bash @code{cd} and @code{pwd} builtins (@pxref{Bourne Shell Builtins})
+each take @option{-L} and @option{-P} options to switch between logical and
+physical modes.
+
+@item
+Bash allows a function to override a builtin with the same name, and provides
+access to that builtin's functionality within the function via the
+@code{builtin} and @code{command} builtins (@pxref{Bash Builtins}).
+
+@item
+The @code{command} builtin allows selective disabling of functions
+when command lookup is performed (@pxref{Bash Builtins}).
+
+@item
+Individual builtins may be enabled or disabled using the @code{enable}
+builtin (@pxref{Bash Builtins}).
+
+@item
+The Bash @code{exec} builtin takes additional options that allow users
+to control the contents of the environment passed to the executed
+command, and what the zeroth argument to the command is to be
+(@pxref{Bourne Shell Builtins}).
+
+@item
+Shell functions may be exported to children via the environment
+using @code{export -f} (@pxref{Shell Functions}).
+
+@item
+The Bash @code{export}, @code{readonly}, and @code{declare} builtins can
+take a @option{-f} option to act on shell functions, a @option{-p} option to
+display variables with various attributes set in a format that can be
+used as shell input, a @option{-n} option to remove various variable
+attributes, and @samp{name=value} arguments to set variable attributes
+and values simultaneously.
+
+@item
+The Bash @code{hash} builtin allows a name to be associated with
+an arbitrary filename, even when that filename cannot be found by
+searching the @env{$PATH}, using @samp{hash -p}
+(@pxref{Bourne Shell Builtins}).
+
+@item
+Bash includes a @code{help} builtin for quick reference to shell
+facilities (@pxref{Bash Builtins}).
+
+@item
+The @code{printf} builtin is available to display formatted output
+(@pxref{Bash Builtins}).
+
+@item
+The Bash @code{read} builtin (@pxref{Bash Builtins})
+will read a line ending in @samp{\} with
+the @option{-r} option, and will use the @env{REPLY} variable as a
+default if no non-option arguments are supplied.
+The Bash @code{read} builtin
+also accepts a prompt string with the @option{-p} option and will use
+Readline to obtain the line when given the @option{-e} option.
+The @code{read} builtin also has additional options to control input:
+the @option{-s} option will turn off echoing of input characters as
+they are read, the @option{-t} option will allow @code{read} to time out
+if input does not arrive within a specified number of seconds, the
+@option{-n} option will allow reading only a specified number of
+characters rather than a full line, and the @option{-d} option will read
+until a particular character rather than newline.
+
+@item
+The @code{return} builtin may be used to abort execution of scripts
+executed with the @code{.} or @code{source} builtins
+(@pxref{Bourne Shell Builtins}).
+
+@item
+Bash includes the @code{shopt} builtin, for finer control of shell
+optional capabilities (@pxref{The Shopt Builtin}), and allows these options
+to be set and unset at shell invocation (@pxref{Invoking Bash}).
+
+@item
+Bash has much more optional behavior controllable with the @code{set}
+builtin (@pxref{The Set Builtin}).
+
+@item
+The @samp{-x} (@option{xtrace}) option displays commands other than
+simple commands when performing an execution trace
+(@pxref{The Set Builtin}).
+
+@item
+The @code{test} builtin (@pxref{Bourne Shell Builtins})
+is slightly different, as it implements the @sc{posix} algorithm,
+which specifies the behavior based on the number of arguments.
+
+@item
+Bash includes the @code{caller} builtin, which displays the context of
+any active subroutine call (a shell function or a script executed with
+the @code{.} or @code{source} builtins).  This supports the Bash
+debugger.
+
+@item
+The @code{trap} builtin (@pxref{Bourne Shell Builtins}) allows a
+@code{DEBUG} pseudo-signal specification, similar to @code{EXIT}.
+Commands specified with a @code{DEBUG} trap are executed before every
+simple command, @code{for} command, @code{case} command,
+@code{select} command, every arithmetic @code{for} command, and before
+the first command executes in a shell function.
+The @code{DEBUG} trap is not inherited by shell functions unless the
+function has been given the @code{trace} attribute or the
+@code{functrace} option has been enabled using the @code{shopt} builtin.
+The @code{extdebug} shell option has additional effects on the
+@code{DEBUG} trap.
+
+The @code{trap} builtin (@pxref{Bourne Shell Builtins}) allows an
+@code{ERR} pseudo-signal specification, similar to @code{EXIT} and @code{DEBUG}.
+Commands specified with an @code{ERR} trap are executed after a simple
+command fails, with a few exceptions.
+The @code{ERR} trap is not inherited by shell functions unless the
+@code{-o errtrace} option to the @code{set} builtin is enabled.
+
+The @code{trap} builtin (@pxref{Bourne Shell Builtins}) allows a
+@code{RETURN} pseudo-signal specification, similar to
+@code{EXIT} and @code{DEBUG}.
+Commands specified with a @code{RETURN} trap are executed before
+execution resumes after a shell function or a shell script executed with
+@code{.} or @code{source} returns.
+The @code{RETURN} trap is not inherited by shell functions unless the
+function has been given the @code{trace} attribute or the
+@code{functrace} option has been enabled using the @code{shopt} builtin.
+
+@item
+The Bash @code{type} builtin is more extensive and gives more information
+about the names it finds (@pxref{Bash Builtins}).
+
+@item
+The Bash @code{umask} builtin permits a @option{-p} option to cause
+the output to be displayed in the form of a @code{umask} command
+that may be reused as input (@pxref{Bourne Shell Builtins}).
+
+@item
+Bash implements a @code{csh}-like directory stack, and provides the
+@code{pushd}, @code{popd}, and @code{dirs} builtins to manipulate it
+(@pxref{The Directory Stack}).
+Bash also makes the directory stack visible as the value of the
+@env{DIRSTACK} shell variable.
+
+@item
+Bash interprets special backslash-escaped characters in the prompt
+strings when interactive (@pxref{Controlling the Prompt}).
+
+@item
+The Bash restricted mode is more useful (@pxref{The Restricted Shell});
+the SVR4.2 shell restricted mode is too limited.
+
+@item
+The @code{disown} builtin can remove a job from the internal shell
+job table (@pxref{Job Control Builtins}) or suppress the sending
+of @code{SIGHUP} to a job when the shell exits as the result of a
+@code{SIGHUP}.
+
+@item
+Bash includes a number of features to support a separate debugger for
+shell scripts.
+
+@item
+The SVR4.2 shell has two privilege-related builtins
+(@code{mldmode} and @code{priv}) not present in Bash.
+
+@item
+Bash does not have the @code{stop} or @code{newgrp} builtins.
+
+@item
+Bash does not use the @env{SHACCT} variable or perform shell accounting.
+
+@item
+The SVR4.2 @code{sh} uses a @env{TIMEOUT} variable like Bash uses
+@env{TMOUT}.
+
+@end itemize
+
+@noindent
+More features unique to Bash may be found in @ref{Bash Features}.
+
+
+@appendixsec Implementation Differences From The SVR4.2 Shell
+
+Since Bash is a completely new implementation, it does not suffer from
+many of the limitations of the SVR4.2 shell.  For instance:
+
+@itemize @bullet
+
+@item
+Bash does not fork a subshell when redirecting into or out of
+a shell control structure such as  an @code{if} or @code{while}
+statement.
+
+@item
+Bash does not allow unbalanced quotes.  The SVR4.2 shell will silently
+insert a needed closing quote at @code{EOF} under certain circumstances.
+This can be the cause of some hard-to-find errors.
+
+@item
+The SVR4.2 shell uses a baroque memory management scheme based on
+trapping @code{SIGSEGV}.  If the shell is started from a process with
+@code{SIGSEGV} blocked (e.g., by using the @code{system()} C library
+function call), it misbehaves badly.
+
+@item
+In a questionable attempt at security, the SVR4.2 shell,
+when invoked without the @option{-p} option, will alter its real
+and effective @sc{uid} and @sc{gid} if they are less than some
+magic threshold value, commonly 100.
+This can lead to unexpected results.
+
+@item
+The SVR4.2 shell does not allow users to trap @code{SIGSEGV},
+@code{SIGALRM}, or @code{SIGCHLD}.
+
+@item
+The SVR4.2 shell does not allow the @env{IFS}, @env{MAILCHECK},
+@env{PATH}, @env{PS1}, or @env{PS2} variables to be unset.
+
+@item
+The SVR4.2 shell treats @samp{^} as the undocumented equivalent of
+@samp{|}.
+
+@item
+Bash allows multiple option arguments when it is invoked (@code{-x -v});
+the SVR4.2 shell allows only one option argument (@code{-xv}).  In
+fact, some versions of the shell dump core if the second argument begins
+with a @samp{-}.
+
+@item
+The SVR4.2 shell exits a script if any builtin fails; Bash exits
+a script only if one of the @sc{posix} special builtins fails, and
+only for certain failures, as enumerated in the @sc{posix} standard.
+
+@item 
+The SVR4.2 shell behaves differently when invoked as @code{jsh}
+(it turns on job control).

+BBAASSHH BBUUIILLTTIINN CCOOMMMMAANNDDSS
+       Unless otherwise noted, each builtin command documented in this section
+       as accepting options preceded by -- accepts ---- to signify the end of the
+       options.  The ::, ttrruuee, ffaallssee, and tteesstt/[[ builtins do not accept options
+       and do not treat ---- specially.  The eexxiitt, llooggoouutt, rreettuurrnn,  bbrreeaakk,  ccoonn--
+       ttiinnuuee,  lleett,  and sshhiifftt builtins accept and process arguments beginning
+       with -- without requiring ----.  Other builtins that accept arguments  but
+       are  not  specified  as accepting options interpret arguments beginning
+       with -- as invalid options and require ---- to  prevent  this  interpreta-
+       tion.
+       :: [_a_r_g_u_m_e_n_t_s]
+              No  effect;  the command does nothing beyond expanding _a_r_g_u_m_e_n_t_s
+              and performing any specified redirections.  The return status is
+              zero.
+
+        ..  _f_i_l_e_n_a_m_e [_a_r_g_u_m_e_n_t_s]
+       ssoouurrccee _f_i_l_e_n_a_m_e [_a_r_g_u_m_e_n_t_s]
+              Read and execute commands from _f_i_l_e_n_a_m_e in the current shell en-
+              vironment and return the exit status of the  last  command  exe-
+              cuted  from  _f_i_l_e_n_a_m_e.   If  _f_i_l_e_n_a_m_e  does not contain a slash,
+              filenames in PPAATTHH are used  to  find  the  directory  containing
+              _f_i_l_e_n_a_m_e, but _f_i_l_e_n_a_m_e does not need to be executable.  The file
+              searched for in PPAATTHH need not be executable.  When bbaasshh  is  not
+              in  _p_o_s_i_x  _m_o_d_e, it searches the current directory if no file is
+              found in PPAATTHH.  If the ssoouurrcceeppaatthh option to  the  sshhoopptt  builtin
+              command  is  turned off, the PPAATTHH is not searched.  If any _a_r_g_u_-
+              _m_e_n_t_s are supplied, they become the positional  parameters  when
+              _f_i_l_e_n_a_m_e  is  executed.  Otherwise the positional parameters are
+              unchanged.  If the --TT option is enabled, .. inherits any trap  on
+              DDEEBBUUGG; if it is not, any DDEEBBUUGG trap string is saved and restored
+              around the call to .., and .. unsets the DDEEBBUUGG trap while it  exe-
+              cutes.  If --TT is not set, and the sourced file changes the DDEEBBUUGG
+              trap, the new value is retained when ..  completes.   The  return
+              status  is  the  status  of  the  last command exited within the
+              script (0 if no commands are executed), and false if _f_i_l_e_n_a_m_e is
+              not found or cannot be read.
+
+       aalliiaass [--pp] [_n_a_m_e[=_v_a_l_u_e] ...]
+              AAlliiaass with no arguments or with the --pp option prints the list of
+              aliases in the form aalliiaass _n_a_m_e=_v_a_l_u_e on standard  output.   When
+              arguments  are supplied, an alias is defined for each _n_a_m_e whose
+              _v_a_l_u_e is given.  A trailing space in _v_a_l_u_e causes the next  word
+              to be checked for alias substitution when the alias is expanded.
+              For each _n_a_m_e in the argument list for which no  _v_a_l_u_e  is  sup-
+              plied,  the  name  and value of the alias is printed.  AAlliiaass re-
+              turns true unless a _n_a_m_e is given for which no  alias  has  been
+              defined.
+
+       bbgg [_j_o_b_s_p_e_c ...]
+              Resume  each  suspended  job _j_o_b_s_p_e_c in the background, as if it
+              had been started with &&.  If _j_o_b_s_p_e_c is not present, the shell's
+              notion  of the _c_u_r_r_e_n_t _j_o_b is used.  bbgg _j_o_b_s_p_e_c returns 0 unless
+              run when job control is disabled or, when run with  job  control
+              enabled,  any  specified  _j_o_b_s_p_e_c  was  not found or was started
+              without job control.

+              Display current rreeaaddlliinnee key and function bindings, bind  a  key
+              sequence  to  a  rreeaaddlliinnee  function  or macro, or set a rreeaaddlliinnee
+              variable.  Each non-option argument is a command as it would ap-
+              pear  in  a  rreeaaddlliinnee  initialization file such as _._i_n_p_u_t_r_c, but
+              each binding or command must be passed as a  separate  argument;
+              e.g.,  '"\C-x\C-r":  re-read-init-file'.   Options, if supplied,
+              have the following meanings:
+              --mm _k_e_y_m_a_p
+                     Use _k_e_y_m_a_p as the keymap to be affected by the subsequent
+                     bindings.  Acceptable _k_e_y_m_a_p names are _e_m_a_c_s_, _e_m_a_c_s_-_s_t_a_n_-
+                     _d_a_r_d_, _e_m_a_c_s_-_m_e_t_a_, _e_m_a_c_s_-_c_t_l_x_,  _v_i_,  _v_i_-_m_o_v_e_,  _v_i_-_c_o_m_m_a_n_d,
+                     and  _v_i_-_i_n_s_e_r_t.   _v_i is equivalent to _v_i_-_c_o_m_m_a_n_d (_v_i_-_m_o_v_e
+                     is also a synonym); _e_m_a_c_s is  equivalent  to  _e_m_a_c_s_-_s_t_a_n_-
+                     _d_a_r_d.
+              --ll     List the names of all rreeaaddlliinnee functions.
+              --pp     Display  rreeaaddlliinnee  function  names and bindings in such a
+                     way that they can be re-read.
+              --PP     List current rreeaaddlliinnee function names and bindings.

+              --vv     Display  rreeaaddlliinnee variable names and values in such a way
+                     that they can be re-read.
+              --VV     List current rreeaaddlliinnee variable names and values.

+              specified,  break  _n  levels.   _n must be >= 1.  If _n is greater
+              than the number of enclosing loops, all enclosing loops are  ex-

+
+       bbuuiillttiinn _s_h_e_l_l_-_b_u_i_l_t_i_n [_a_r_g_u_m_e_n_t_s]
+              Execute the specified shell builtin, passing it  _a_r_g_u_m_e_n_t_s,  and
+              return its exit status.  This is useful when defining a function
+              whose name is the same as a shell builtin, retaining  the  func-
+              tionality of the builtin within the function.  The ccdd builtin is
+              commonly redefined this way.  The  return  status  is  false  if
+              _s_h_e_l_l_-_b_u_i_l_t_i_n is not a shell builtin command.
+
+       ccaalllleerr [_e_x_p_r]
+              Returns the context of any active subroutine call (a shell func-
+              tion or a script executed with the .. or ssoouurrccee builtins).  With-
+              out _e_x_p_r, ccaalllleerr displays the line number and source filename of
+              the current subroutine call.  If a non-negative integer is  sup-
+              plied as _e_x_p_r, ccaalllleerr displays the line number, subroutine name,
+              and source file corresponding to that position  in  the  current
+              execution  call  stack.  This extra information may be used, for
+              example, to print a stack trace.  The current frame is frame  0.
+              The  return  value is 0 unless the shell is not executing a sub-
+              routine call or _e_x_p_r does not correspond to a valid position  in
+              the call stack.
+
+       ccdd [--LL|[--PP [--ee]] [-@]] [_d_i_r]
+              Change  the  current  directory to _d_i_r.  if _d_i_r is not supplied,
+              the value of the HHOOMMEE shell variable is the default.  The  vari-
+              able CCDDPPAATTHH defines the search path for the directory containing
+              _d_i_r: each directory name in CCDDPPAATTHH is searched for _d_i_r.   Alter-
+              native  directory  names in CCDDPPAATTHH are separated by a colon (:).
+              A null directory name in CCDDPPAATTHH is the same as the  current  di-
+              rectory,  i.e., ``..''.  If _d_i_r begins with a slash (/), then CCDD--
+              PPAATTHH is not used.  The --PP option causes ccdd to use  the  physical
+              directory structure by resolving symbolic links while traversing
+              _d_i_r and before processing instances of _._. in _d_i_r (see  also  the
+              --PP option to the sseett builtin command); the --LL option forces sym-
+              bolic links to be followed by resolving the link after  process-
+              ing  instances  of  _._. in _d_i_r.  If _._. appears in _d_i_r, it is pro-
+              cessed by removing the immediately previous  pathname  component
+              from  _d_i_r,  back  to a slash or the beginning of _d_i_r.  If the --ee
+              option is supplied with --PP, and the  current  working  directory
+              cannot  be  successfully determined after a successful directory
+              change, ccdd will return an unsuccessful status.  On systems  that
+              support it, the --@@ option presents the extended attributes asso-
+              ciated with a file as a directory.  An argument  of  --  is  con-
+              verted  to $$OOLLDDPPWWDD before the directory change is attempted.  If
+              a non-empty directory name from CCDDPPAATTHH is used, or if --  is  the
+              first  argument, and the directory change is successful, the ab-
+              solute pathname of the new working directory is written  to  the
+              standard output.  If the directory change is successful, ccdd sets
+              the value of the PPWWDD environment variable to the  new  directory
+              name,  and  sets the OOLLDDPPWWDD environment variable to the value of
+              the current working directory before  the  change.   The  return
+              value  is  true if the directory was successfully changed; false
+              otherwise.
+
+       ccoommmmaanndd [--ppVVvv] _c_o_m_m_a_n_d [_a_r_g ...]
+              Run _c_o_m_m_a_n_d with _a_r_g_s  suppressing  the  normal  shell  function
+              lookup.  Only builtin commands or commands found in the PPAATTHH are
+              executed.  If the --pp option is given, the search for _c_o_m_m_a_n_d  is
+              performed  using  a default value for PPAATTHH that is guaranteed to
+              find all of the standard utilities.  If either the --VV or --vv  op-
+              tion  is  supplied, a description of _c_o_m_m_a_n_d is printed.  The --vv
+              option causes a single word indicating the command  or  filename
+              used to invoke _c_o_m_m_a_n_d to be displayed; the --VV option produces a
+              more verbose description.  If the --VV or --vv option  is  supplied,
+              the  exit  status  is  0 if _c_o_m_m_a_n_d was found, and 1 if not.  If
+              neither option is supplied and an error occurred or _c_o_m_m_a_n_d can-
+              not  be found, the exit status is 127.  Otherwise, the exit sta-
+              tus of the ccoommmmaanndd builtin is the exit status of _c_o_m_m_a_n_d.
+
+       ccoommppggeenn [_o_p_t_i_o_n] [_w_o_r_d]
+              Generate possible completion matches for _w_o_r_d according  to  the
+              _o_p_t_i_o_ns,  which  may  be  any  option  accepted  by the ccoommpplleettee
+              builtin with the exception of --pp and --rr, and write  the  matches
+              to  the  standard  output.  When using the --FF or --CC options, the
+              various shell variables set by the programmable  completion  fa-
+              cilities, while available, will not have useful values.
+
+              The matches will be generated in the same way as if the program-
+              mable completion code had generated them directly from a comple-
+              tion  specification  with the same flags.  If _w_o_r_d is specified,
+              only those completions matching _w_o_r_d will be displayed.
+
+              The return value is true unless an invalid option  is  supplied,
+              or no matches were generated.

+              --pp option is supplied, or if no options are  supplied,  existing
+              completion  specifications are printed in a way that allows them
+              to be reused as input.  The --rr option removes a completion spec-
+              ification  for each _n_a_m_e, or, if no _n_a_m_es are supplied, all com-
+              pletion specifications.  The --DD option indicates that other sup-
+              plied  options  and actions should apply to the ``default'' com-
+              mand completion; that is, completion attempted on a command  for
+              which  no completion has previously been defined.  The --EE option
+              indicates that other supplied options and actions  should  apply
+              to  ``empty''  command completion; that is, completion attempted
+              on a blank line.  The --II option indicates  that  other  supplied
+              options  and  actions  should apply to completion on the initial
+              non-assignment word on the line, or after  a  command  delimiter
+              such  as  ;;  or ||, which is usually command name completion.  If
+              multiple options are supplied, the --DD  option  takes  precedence
+              over --EE, and both take precedence over --II.  If any of --DD, --EE, or
+              --II are supplied, any other _n_a_m_e  arguments  are  ignored;  these
+              completions only apply to the case specified by the option.
+

+              sion before the ccoommpplleettee builtin is invoked.

+                      rent command line.  When it finishes, the possible  com-

+                      The pathname expansion pattern _g_l_o_b_p_a_t  is  expanded  to
+                      generate the possible completions.

+                      _p_r_e_f_i_x  is  added at the beginning of each possible com-

+                      _s_u_f_f_i_x is appended to each possible completion after all
+                      other options have been applied.
+              --WW _w_o_r_d_l_i_s_t
+                      The  _w_o_r_d_l_i_s_t  is  split using the characters in the IIFFSS
+                      special variable as delimiters, and each resultant  word
+                      is  expanded.  Shell quoting is honored within _w_o_r_d_l_i_s_t,
+                      in order to provide a mechanism for the words to contain
+                      shell  metacharacters or characters in the value of IIFFSS.
+                      The possible completions are the members of  the  resul-
+                      tant list which match the word being completed.
+              --XX _f_i_l_t_e_r_p_a_t
+                      _f_i_l_t_e_r_p_a_t  is  a pattern as used for pathname expansion.
+                      It is applied to the list of possible completions gener-
+                      ated  by  the  preceding options and arguments, and each
+                      completion matching _f_i_l_t_e_r_p_a_t is removed from the  list.
+                      A  leading  !!  in _f_i_l_t_e_r_p_a_t negates the pattern; in this
+                      case, any completion not matching _f_i_l_t_e_r_p_a_t is removed.
+
+              The return value is true unless an invalid option  is  supplied,

+              scribed  above.  The --DD option indicates that other supplied op-

+              is,  completion  attempted  on a command for which no completion
+              has previously been defined.  The --EE option indicates that other
+              supplied  options  should apply to ``empty'' command completion;
+              that is, completion attempted on a blank line.   The  --II  option
+              indicates that other supplied options should apply to completion
+              on the initial non-assignment word on the line, or after a  com-

+              Declare  variables and/or give them attributes.  If no _n_a_m_es are
+              given then display the values of variables.  The --pp option  will
+              display the attributes and values of each _n_a_m_e.  When --pp is used
+              with _n_a_m_e arguments, additional options, other than --ff  and  --FF,
+              are  ignored.   When  --pp  is supplied without _n_a_m_e arguments, it
+              will display the attributes and values of all  variables  having
+              the attributes specified by the additional options.  If no other
+              options are supplied with  --pp,  ddeeccllaarree  will  display  the  at-
+              tributes  and values of all shell variables.  The --ff option will
+              restrict the display to shell functions.  The --FF option inhibits
+              the  display of function definitions; only the function name and
+              attributes are printed.  If the eexxttddeebbuugg shell option is enabled
+              using  sshhoopptt,  the  source  file name and line number where each
+              _n_a_m_e is defined are displayed as well.  The  --FF  option  implies
+              --ff.  The --gg option forces variables to be created or modified at
+              the global scope, even when ddeeccllaarree is executed in a shell func-
+              tion.   It  is ignored in all other cases.  The --II option causes
+              local variables to inherit the attributes  (except  the  _n_a_m_e_r_e_f
+              attribute) and value of any existing variable with the same _n_a_m_e
+              at a surrounding scope.  If there is no existing  variable,  the
+              local variable is initially unset.  The following options can be
+              used to restrict output to variables with the  specified  attri-
+              bute or to give variables attributes:
+              --aa     Each  _n_a_m_e  is  an  indexed array variable (see AArrrraayyss in
+                     _b_a_s_h_(_1_)).
+              --AA     Each _n_a_m_e is an associative array variable (see AArrrraayyss in
+                     _b_a_s_h_(_1_)).
+              --ff     Use function names only.
+              --ii     The variable is treated as an integer; arithmetic evalua-
+                     tion (see AARRIITTHHMMEETTIICC EEVVAALLUUAATTIIOONN in _b_a_s_h_(_1_)) is  performed
+                     when the variable is assigned a value.
+              --ll     When  the  variable  is  assigned a value, all upper-case
+                     characters are converted to lower-case.   The  upper-case
+                     attribute is disabled.
+              --nn     Give  each  _n_a_m_e  the _n_a_m_e_r_e_f attribute, making it a name
+                     reference to another variable.  That  other  variable  is
+                     defined  by  the  value of _n_a_m_e.  All references, assign-
+                     ments, and attribute modifications to _n_a_m_e, except  those
+                     using  or changing the --nn attribute itself, are performed
+                     on the variable referenced by _n_a_m_e's value.  The  nameref
+                     attribute cannot be applied to array variables.
+              --rr     Make _n_a_m_es readonly.  These names cannot then be assigned
+                     values by subsequent assignment statements or unset.
+              --tt     Give each _n_a_m_e the _t_r_a_c_e attribute.  Traced functions in-
+                     herit  the DDEEBBUUGG and RREETTUURRNN traps from the calling shell.
+                     The trace attribute has no special meaning for variables.
+              --uu     When the variable is assigned  a  value,  all  lower-case
+                     characters  are  converted to upper-case.  The lower-case
+                     attribute is disabled.
+              --xx     Mark _n_a_m_es for export to subsequent commands via the  en-
+                     vironment.
+
+              Using  `+'  instead of `-' turns off the attribute instead, with
+              the exceptions that ++aa and ++AA may not be used to  destroy  array
+              variables  and  ++rr will not remove the readonly attribute.  When
+              used in a function, ddeeccllaarree and ttyyppeesseett make each _n_a_m_e local, as
+              with  the llooccaall command, unless the --gg option is supplied.  If a
+              variable name is followed by =_v_a_l_u_e, the value of  the  variable
+              is  set  to _v_a_l_u_e.  When using --aa or --AA and the compound assign-
+              ment syntax to create array variables, additional attributes  do
+              not  take effect until subsequent assignments.  The return value
+              is 0 unless an invalid option is encountered, an attempt is made
+              to define a function using ``-f foo=bar'', an attempt is made to

+              sign a value to an array variable without using the compound as-
+              signment syntax (see AArrrraayyss in _b_a_s_h_(_1_)), one of the _n_a_m_e_s is not
+              a  valid  shell  variable  name,  an attempt is made to turn off
+              readonly status for a readonly variable, an attempt is  made  to

+       ddiirrss [[--ccllppvv]] [[++_n]] [[--_n]]
+              Without options, displays the list of currently  remembered  di-
+              rectories.   The default display is on a single line with direc-
+              tory names separated by spaces.  Directories are  added  to  the
+              list  with  the  ppuusshhdd command; the ppooppdd command removes entries
+              from the list.  The current directory is always the first direc-
+              tory in the stack.
+              --cc     Clears  the  directory  stack  by deleting all of the en-
+                     tries.
+              --ll     Produces a listing  using  full  pathnames;  the  default
+                     listing format uses a tilde to denote the home directory.
+              --pp     Print the directory stack with one entry per line.

+                     shown by ddiirrss when invoked without options, starting with
+                     zero.

+              option  is  supplied, the _c_u_r_r_e_n_t _j_o_b is used.  If the --hh option
+              is given, each _j_o_b_s_p_e_c is not removed from  the  table,  but  is
+              marked  so  that  SSIIGGHHUUPP is not sent to the job if the shell re-
+              ceives a SSIIGGHHUUPP.  If no _j_o_b_s_p_e_c is supplied, the --aa option means
+              to  remove or mark all jobs; the --rr option without a _j_o_b_s_p_e_c ar-
+              gument restricts operation to running jobs.  The return value is

+              Enable  and disable builtin shell commands.  Disabling a builtin
+              allows a disk command which has the same name as a shell builtin
+              to  be  executed without specifying a full pathname, even though
+              the shell normally searches for builtins before  disk  commands.
+              If  --nn  is used, each _n_a_m_e is disabled; otherwise, _n_a_m_e_s are en-
+              abled.  For example, to use the tteesstt binary found via  the  PPAATTHH
+              instead  of  the  shell builtin version, run ``enable -n test''.
+              The --ff option means to load the new builtin  command  _n_a_m_e  from
+              shared object _f_i_l_e_n_a_m_e, on systems that support dynamic loading.
+              Bash will use the value of the BBAASSHH__LLOOAADDAABBLLEESS__PPAATTHH variable as a
+              colon-separated list of directories in which to search for _f_i_l_e_-
+              _n_a_m_e.  The default is  system-dependent.   The  --dd  option  will
+              delete  a  builtin  previously loaded with --ff.  If no _n_a_m_e argu-
+              ments are given, or if the --pp option  is  supplied,  a  list  of
+              shell  builtins is printed.  With no other option arguments, the
+              list consists of all enabled shell builtins.  If --nn is supplied,
+              only disabled builtins are printed.  If --aa is supplied, the list
+              printed includes all builtins, with an indication of whether  or

+       eexxeecc [--ccll] [--aa _n_a_m_e] [_c_o_m_m_a_n_d [_a_r_g_u_m_e_n_t_s]]
+              If _c_o_m_m_a_n_d is specified, it replaces the shell.  No new  process
+              is  created.  The _a_r_g_u_m_e_n_t_s become the arguments to _c_o_m_m_a_n_d.  If
+              the --ll option is supplied, the shell places a dash at the begin-
+              ning of the zeroth argument passed to _c_o_m_m_a_n_d.  This is what _l_o_-
+              _g_i_n(1) does.  The --cc option causes _c_o_m_m_a_n_d to be  executed  with
+              an  empty environment.  If --aa is supplied, the shell passes _n_a_m_e
+              as the zeroth argument to the executed command.  If _c_o_m_m_a_n_d can-
+              not  be executed for some reason, a non-interactive shell exits,
+              unless the eexxeeccffaaiill shell option is enabled.  In that  case,  it
+              returns  failure.   An  interactive shell returns failure if the
+              file cannot be executed.  A subshell  exits  unconditionally  if
+              eexxeecc  fails.  If _c_o_m_m_a_n_d is not specified, any redirections take
+              effect in the current shell, and the return  status  is  0.   If
+              there is a redirection error, the return status is 1.
+
+       eexxiitt [_n]
+              Cause  the  shell  to exit with a status of _n.  If _n is omitted,
+              the exit status is that of the last command executed.  A trap on
+              EEXXIITT is executed before the shell terminates.
+
+       eexxppoorrtt [--ffnn] [_n_a_m_e[=_w_o_r_d]] ...
+       eexxppoorrtt --pp
+              The  supplied _n_a_m_e_s are marked for automatic export to the envi-
+              ronment of subsequently executed commands.  If the --ff option  is
+              given,  the _n_a_m_e_s refer to functions.  If no _n_a_m_e_s are given, or
+              if the --pp option is supplied, a list of names  of  all  exported
+              variables  is printed.  The --nn option causes the export property
+              to be removed from each _n_a_m_e.  If a variable name is followed by
+              =_w_o_r_d, the value of the variable is set to _w_o_r_d.  eexxppoorrtt returns
+              an exit status of 0 unless an invalid option is encountered, one
+              of  the  _n_a_m_e_s is not a valid shell variable name, or --ff is sup-
+              plied with a _n_a_m_e that is not a function.
+
+       ffcc [--ee _e_n_a_m_e] [--llnnrr] [_f_i_r_s_t] [_l_a_s_t]
+       ffcc --ss [_p_a_t=_r_e_p] [_c_m_d]
+              The first form selects a range of commands from  _f_i_r_s_t  to  _l_a_s_t
+              from  the  history  list  and  displays or edits and re-executes
+              them.  _F_i_r_s_t and _l_a_s_t may be specified as a  string  (to  locate
+              the  last command beginning with that string) or as a number (an
+              index into the history list, where a negative number is used  as
+              an  offset  from  the  current command number).  When listing, a
+              _f_i_r_s_t or _l_a_s_t of 0 is equivalent to -1 and -0 is  equivalent  to
+              the  current  command  (usually  the ffcc command); otherwise 0 is
+              equivalent to -1 and -0 is invalid.  If _l_a_s_t is  not  specified,
+              it  is  set  to the current command for listing (so that ``fc -l
+              -10'' prints the last 10 commands) and to _f_i_r_s_t  otherwise.   If
+              _f_i_r_s_t  is  not  specified, it is set to the previous command for
+              editing and -16 for listing.
+
+              The --nn option suppresses the command numbers when listing.   The
+              --rr  option reverses the order of the commands.  If the --ll option
+              is given, the commands are listed on  standard  output.   Other-
+              wise,  the editor given by _e_n_a_m_e is invoked on a file containing
+              those commands.  If _e_n_a_m_e is not given, the value of the  FFCCEEDDIITT
+              variable  is used, and the value of EEDDIITTOORR if FFCCEEDDIITT is not set.
+              If neither variable is set, _v_i is used.  When  editing  is  com-
+              plete, the edited commands are echoed and executed.
+
+              In  the  second form, _c_o_m_m_a_n_d is re-executed after each instance
+              of _p_a_t is replaced by _r_e_p.  _C_o_m_m_a_n_d is interpreted the  same  as
+              _f_i_r_s_t  above.  A useful alias to use with this is ``r="fc -s"'',
+              so that typing ``r cc'' runs the  last  command  beginning  with
+              ``cc'' and typing ``r'' re-executes the last command.
+
+              If  the  first form is used, the return value is 0 unless an in-
+              valid option is encountered or _f_i_r_s_t  or  _l_a_s_t  specify  history
+              lines  out  of  range.  If the --ee option is supplied, the return
+              value is the value of the last command executed or failure if an
+              error occurs with the temporary file of commands.  If the second
+              form is used, the return status is that of the  command  re-exe-
+              cuted,  unless  _c_m_d  does  not  specify a valid history line, in
+              which case ffcc returns failure.
+
+       ffgg [_j_o_b_s_p_e_c]
+              Resume _j_o_b_s_p_e_c in the foreground, and make it the  current  job.
+              If _j_o_b_s_p_e_c is not present, the shell's notion of the _c_u_r_r_e_n_t _j_o_b
+              is used.  The return value is that of the  command  placed  into
+              the  foreground,  or failure if run when job control is disabled
+              or, when run with job control enabled, if _j_o_b_s_p_e_c does not spec-
+              ify  a  valid  job  or  _j_o_b_s_p_e_c specifies a job that was started
+              without job control.
+
+       ggeettooppttss _o_p_t_s_t_r_i_n_g _n_a_m_e [_a_r_g _._._.]
+              ggeettooppttss is used by shell procedures to parse positional  parame-
+              ters.   _o_p_t_s_t_r_i_n_g  contains  the  option characters to be recog-
+              nized; if a character is followed by a colon, the option is  ex-
+              pected to have an argument, which should be separated from it by
+              white space.  The colon and question mark characters may not  be
+              used  as  option  characters.   Each time it is invoked, ggeettooppttss
+              places the next option in the shell variable _n_a_m_e,  initializing
+              _n_a_m_e if it does not exist, and the index of the next argument to
+              be processed into the variable OOPPTTIINNDD.  OOPPTTIINNDD is initialized to
+              1 each time the shell or a shell script is invoked.  When an op-
+              tion requires an argument, ggeettooppttss places that argument into the
+              variable OOPPTTAARRGG.  The shell does not reset OOPPTTIINNDD automatically;
+              it must be manually reset  between  multiple  calls  to  ggeettooppttss
+              within  the  same shell invocation if a new set of parameters is
+              to be used.
+
+              When the end of options is encountered, ggeettooppttss exits with a re-
+              turn value greater than zero.  OOPPTTIINNDD is set to the index of the
+              first non-option argument, and _n_a_m_e is set to ?.
+
+              ggeettooppttss normally parses the positional parameters, but  if  more
+              arguments  are  supplied as _a_r_g values, ggeettooppttss parses those in-
+              stead.
+
+              ggeettooppttss can report errors in two ways.  If the  first  character
+              of  _o_p_t_s_t_r_i_n_g  is  a  colon, _s_i_l_e_n_t error reporting is used.  In
+              normal operation, diagnostic messages are printed  when  invalid
+              options  or  missing  option  arguments are encountered.  If the
+              variable OOPPTTEERRRR is set to 0, no  error  messages  will  be  dis-
+              played, even if the first character of _o_p_t_s_t_r_i_n_g is not a colon.
+
+              If an invalid option is seen, ggeettooppttss places ? into _n_a_m_e and, if
+              not silent, prints an  error  message  and  unsets  OOPPTTAARRGG.   If
+              ggeettooppttss  is  silent, the option character found is placed in OOPP--
+              TTAARRGG and no diagnostic message is printed.
+
+              If a required argument is not found, and ggeettooppttss is not  silent,
+              a  question  mark  (??) is placed in _n_a_m_e, OOPPTTAARRGG is unset, and a
+              diagnostic message is printed.  If ggeettooppttss  is  silent,  then  a
+              colon  (::)  is  placed  in  _n_a_m_e and OOPPTTAARRGG is set to the option
+              character found.
+
+              ggeettooppttss returns true if an option, specified or unspecified,  is
+              found.  It returns false if the end of options is encountered or
+              an error occurs.
+
+       hhaasshh [--llrr] [--pp _f_i_l_e_n_a_m_e] [--ddtt] [_n_a_m_e]
+              Each time hhaasshh is invoked, the full pathname of the command _n_a_m_e
+              is  determined  by searching the directories in $$PPAATTHH and remem-
+              bered.  Any previously-remembered pathname is discarded.  If the
+              --pp option is supplied, no path search is performed, and _f_i_l_e_n_a_m_e
+              is used as the full filename of  the  command.   The  --rr  option
+              causes the shell to forget all remembered locations.  The --dd op-
+              tion causes the shell to forget the remembered location of  each
+              _n_a_m_e.   If the --tt option is supplied, the full pathname to which
+              each _n_a_m_e corresponds is printed.  If  multiple  _n_a_m_e  arguments
+              are supplied with --tt, the _n_a_m_e is printed before the hashed full
+              pathname.  The --ll option causes output to be displayed in a for-
+              mat  that may be reused as input.  If no arguments are given, or
+              if only --ll is supplied, information about remembered commands is
+              printed.   The  return status is true unless a _n_a_m_e is not found
+              or an invalid option is supplied.

+              Display helpful information about builtin commands.  If  _p_a_t_t_e_r_n
+              is  specified, hheellpp gives detailed help on all commands matching
+              _p_a_t_t_e_r_n; otherwise help for all the builtins and  shell  control

+              With no options, display the command history list with line num-
+              bers.  Lines listed with a ** have been modified.  An argument of
+              _n lists only the last _n lines.  If the shell variable  HHIISSTTTTIIMMEE--
+              FFOORRMMAATT  is  set  and not null, it is used as a format string for
+              _s_t_r_f_t_i_m_e(3) to display the time stamp associated with each  dis-
+              played  history  entry.  No intervening blank is printed between
+              the formatted time stamp and the history line.  If  _f_i_l_e_n_a_m_e  is
+              supplied,  it  is  used as the name of the history file; if not,
+              the value of HHIISSTTFFIILLEE is used.  Options, if supplied,  have  the
+              following meanings:
+              --cc     Clear the history list by deleting all the entries.
+              --dd _o_f_f_s_e_t
+                     Delete  the  history entry at position _o_f_f_s_e_t.  If _o_f_f_s_e_t
+                     is negative, it is interpreted as relative to one greater
+                     than the last history position, so negative indices count
+                     back from the end of the history,  and  an  index  of  -1
+                     refers to the current hhiissttoorryy --dd command.
+              --dd _s_t_a_r_t-_e_n_d
+                     Delete  the  range  of  history entries between positions
+                     _s_t_a_r_t and _e_n_d, inclusive.  Positive and  negative  values
+                     for _s_t_a_r_t and _e_n_d are interpreted as described above.
+              --aa     Append  the  ``new''  history  lines to the history file.
+                     These are history lines entered since  the  beginning  of
+                     the current bbaasshh session, but not already appended to the
+                     history file.
+              --nn     Read the history lines not already read from the  history
+                     file  into the current history list.  These are lines ap-
+                     pended to the history file since  the  beginning  of  the
+                     current bbaasshh session.
+              --rr     Read  the contents of the history file and append them to
+                     the current history list.
+              --ww     Write the current history list to the history file, over-
+                     writing the history file's contents.
+              --pp     Perform  history  substitution  on the following _a_r_g_s and

+                     store  the results in the history list.  Each _a_r_g must be
+                     quoted to disable normal history expansion.
+              --ss     Store the _a_r_g_s in the history list  as  a  single  entry.
+                     The  last  command  in the history list is removed before
+                     the _a_r_g_s are added.
+
+              If the HHIISSTTTTIIMMEEFFOORRMMAATT variable is set, the time  stamp  informa-
+              tion  associated  with each history entry is written to the his-
+              tory file, marked with the history comment character.  When  the
+              history  file  is read, lines beginning with the history comment
+              character followed immediately by a  digit  are  interpreted  as
+              timestamps for the following history entry.  The return value is
+              0 unless an invalid option is encountered, an error occurs while
+              reading  or writing the history file, an invalid _o_f_f_s_e_t or range
+              is supplied as an argument to --dd, or the history expansion  sup-
+              plied as an argument to --pp fails.

+              a  signal  number; _s_i_g_n_u_m is a signal number.  If _s_i_g_s_p_e_c is not
+              present, then SSIIGGTTEERRMM is assumed.  An argument of --ll  lists  the
+              signal  names.   If any arguments are supplied when --ll is given,
+              the names of the signals  corresponding  to  the  arguments  are
+              listed, and the return status is 0.  The _e_x_i_t___s_t_a_t_u_s argument to
+              --ll is a number specifying either a signal  number  or  the  exit
+              status  of  a  process terminated by a signal.  The --LL option is
+              equivalent to --ll.  kkiillll returns true if at least one signal  was
+              successfully sent, or false if an error occurs or an invalid op-
+              tion is encountered.
+
+       lleett _a_r_g [_a_r_g ...]
+              Each _a_r_g is an arithmetic expression to be evaluated (see AARRIITTHH--
+              MMEETTIICC  EEVVAALLUUAATTIIOONN  in _b_a_s_h_(_1_)).  If the last _a_r_g evaluates to 0,
+              lleett returns 1; 0 is returned otherwise.
+
+       llooccaall [_o_p_t_i_o_n] [_n_a_m_e[=_v_a_l_u_e] ... | - ]
+              For each argument, a local variable named _n_a_m_e is  created,  and
+              assigned  _v_a_l_u_e.   The _o_p_t_i_o_n can be any of the options accepted
+              by ddeeccllaarree.  When llooccaall is used within a function, it causes the
+              variable  _n_a_m_e  to have a visible scope restricted to that func-
+              tion and its children.  If _n_a_m_e is -, the set of  shell  options
+              is  made  local to the function in which llooccaall is invoked: shell
+              options changed using the sseett builtin inside  the  function  are
+              restored  to  their  original  values when the function returns.
+              The restore is effected as if a series of sseett commands were exe-
+              cuted  to restore the values that were in place before the func-
+              tion.  With no operands, llooccaall writes a list of local  variables
+              to  the  standard  output.  It is an error to use llooccaall when not
+              within a function.  The return status is 0 unless llooccaall is  used
+              outside  a  function,  an invalid _n_a_m_e is supplied, or _n_a_m_e is a
+              readonly variable.

+              able  _a_r_r_a_y, or from file descriptor _f_d if the --uu option is sup-
+              plied.  The variable MMAAPPFFIILLEE is the default _a_r_r_a_y.  Options,  if
+              supplied, have the following meanings:
+              --dd     The  first  character  of _d_e_l_i_m is used to terminate each
+                     input line, rather than newline.  If _d_e_l_i_m is  the  empty
+                     string, mmaappffiillee will terminate a line when it reads a NUL
+                     character.

+                     index is 0.
+              --ss     Discard the first _c_o_u_n_t lines read.

+                     read.
+              --uu     Read  lines  from file descriptor _f_d instead of the stan-
+                     dard input.
+              --CC     Evaluate _c_a_l_l_b_a_c_k each time _q_u_a_n_t_u_m lines are read.   The
+                     --cc option specifies _q_u_a_n_t_u_m.
+              --cc     Specify  the  number  of  lines read between each call to
+                     _c_a_l_l_b_a_c_k.
+
+              If --CC is specified without --cc,  the  default  quantum  is  5000.
+              When _c_a_l_l_b_a_c_k is evaluated, it is supplied the index of the next
+              array element to be assigned and the line to be assigned to that
+              element  as  additional  arguments.  _c_a_l_l_b_a_c_k is evaluated after
+              the line is read but before the array element is assigned.
+
+              If not supplied with an explicit origin, mmaappffiillee will clear  _a_r_-
+              _r_a_y before assigning to it.
+
+              mmaappffiillee  returns successfully unless an invalid option or option
+              argument is supplied, _a_r_r_a_y is invalid or  unassignable,  or  if
+              _a_r_r_a_y is not an indexed array.
+
+       ppooppdd [-nn] [+_n] [-_n]
+              Removes entries from the directory stack.  The elements are num-
+              bered from 0 starting at the first  directory  listed  by  ddiirrss.
+              With  no  arguments,  ppooppdd  removes  the  top directory from the
+              stack, and changes to the new top directory.  Arguments, if sup-
+              plied, have the following meanings:
+              --nn     Suppresses  the  normal change of directory when removing
+                     directories from the stack, so that only the stack is ma-
+                     nipulated.
+              ++_n     Removes  the _nth entry counting from the left of the list
+                     shown by ddiirrss, starting with zero, from the  stack.   For
+                     example:  ``popd +0'' removes the first directory, ``popd
+                     +1'' the second.
+              --_n     Removes the _nth entry counting from the right of the list
+                     shown  by  ddiirrss, starting with zero.  For example: ``popd
+                     -0'' removes the last directory, ``popd -1'' the next  to
+                     last.
+
+              If  the  top element of the directory stack is modified, and the
+              _-_n option was not supplied, ppooppdd uses the ccdd builtin  to  change
+              to the directory at the top of the stack.  If the ccdd fails, ppooppdd
+              returns a non-zero value.
+
+              Otherwise, ppooppdd returns false if an invalid  option  is  encoun-
+              tered, the directory stack is empty, or a non-existent directory
+              stack entry is specified.
+
+              If the ppooppdd command is successful, bash runs ddiirrss  to  show  the
+              final  contents of the directory stack, and the return status is
+              0.
+
+       pprriinnttff [--vv _v_a_r] _f_o_r_m_a_t [_a_r_g_u_m_e_n_t_s]
+              Write the formatted _a_r_g_u_m_e_n_t_s to the standard output  under  the
+              control  of  the  _f_o_r_m_a_t.  The --vv option causes the output to be
+              assigned to the variable _v_a_r rather than being  printed  to  the
+              standard output.
+
+              The  _f_o_r_m_a_t  is a character string which contains three types of
+              objects: plain characters, which are simply copied  to  standard
+              output,  character  escape  sequences,  which  are converted and
+              copied to the standard output, and format  specifications,  each
+              of  which  causes  printing of the next successive _a_r_g_u_m_e_n_t.  In
+              addition to the standard _p_r_i_n_t_f(1) format specifications, pprriinnttff
+              interprets the following extensions:
+              %%bb     causes pprriinnttff to expand backslash escape sequences in the
+                     corresponding _a_r_g_u_m_e_n_t in the same way as eecchhoo --ee.
+              %%qq     causes pprriinnttff to output the corresponding _a_r_g_u_m_e_n_t  in  a
+                     format that can be reused as shell input.
+              %%QQ     like  %%qq, but applies any supplied precision to the _a_r_g_u_-
+                     _m_e_n_t before quoting it.
+              %%((_d_a_t_e_f_m_t))TT
+                     causes pprriinnttff to output the  date-time  string  resulting
+                     from  using  _d_a_t_e_f_m_t  as a format string for _s_t_r_f_t_i_m_e(3).
+                     The corresponding _a_r_g_u_m_e_n_t is an integer representing the
+                     number  of seconds since the epoch.  Two special argument
+                     values may be used: -1 represents the current  time,  and
+                     -2  represents the time the shell was invoked.  If no ar-
+                     gument is specified, conversion behaves as if -1 had been
+                     given.   This  is an exception to the usual pprriinnttff behav-
+                     ior.
+
+              The %b, %q, and %T directives all use the field width and preci-
+              sion arguments from the format specification and write that many
+              bytes from (or use that wide a field for) the expanded argument,
+              which usually contains more characters than the original.
+
+              Arguments  to non-string format specifiers are treated as C con-
+              stants, except that a leading plus or minus sign is allowed, and
+              if  the leading character is a single or double quote, the value
+              is the ASCII value of the following character.
+
+              The _f_o_r_m_a_t is reused as necessary to consume all  of  the  _a_r_g_u_-
+              _m_e_n_t_s.  If the _f_o_r_m_a_t requires more _a_r_g_u_m_e_n_t_s than are supplied,
+              the extra format specifications behave as if  a  zero  value  or
+              null  string,  as  appropriate,  had  been supplied.  The return
+              value is zero on success, non-zero on failure.
+
+       ppuusshhdd [--nn] [+_n] [-_n]
+       ppuusshhdd [--nn] [_d_i_r]
+              Adds a directory to the top of the directory stack,  or  rotates
+              the  stack,  making the new top of the stack the current working
+              directory.  With no arguments, ppuusshhdd exchanges the top two  ele-
+              ments  of the directory stack.  Arguments, if supplied, have the
+              following meanings:
+              --nn     Suppresses the normal change of directory  when  rotating
+                     or  adding  directories  to  the  stack, so that only the
+                     stack is manipulated.
+              ++_n     Rotates the stack so that  the  _nth  directory  (counting
+                     from  the  left  of the list shown by ddiirrss, starting with
+                     zero) is at the top.
+              --_n     Rotates the stack so that  the  _nth  directory  (counting
+                     from  the  right of the list shown by ddiirrss, starting with
+                     zero) is at the top.
+              _d_i_r    Adds _d_i_r to the directory stack at the top
+
+              After the stack has been modified, if the --nn option was not sup-
+              plied,  ppuusshhdd  uses the ccdd builtin to change to the directory at
+              the top of the stack.  If the ccdd fails, ppuusshhdd returns a non-zero
+              value.
+
+              Otherwise,  if no arguments are supplied, ppuusshhdd returns 0 unless
+              the directory stack  is  empty.   When  rotating  the  directory
+              stack,  ppuusshhdd returns 0 unless the directory stack is empty or a
+              non-existent directory stack element is specified.
+
+              If the ppuusshhdd command is successful, bash runs ddiirrss to  show  the
+              final contents of the directory stack.
+
+       ppwwdd [--LLPP]
+              Print  the  absolute  pathname of the current working directory.
+              The pathname printed contains no symbolic links if the --PP option
+              is supplied or the --oo pphhyyssiiccaall option to the sseett builtin command
+              is enabled.  If the --LL option is used, the pathname printed  may
+              contain  symbolic links.  The return status is 0 unless an error
+              occurs while reading the name of the current directory or an in-
+              valid option is supplied.

+       _p_r_o_m_p_t] [--tt _t_i_m_e_o_u_t] [--uu _f_d] [_n_a_m_e ...]
+              One line is read from the standard input, or from the  file  de-
+              scriptor _f_d supplied as an argument to the --uu option, split into
+              words as described in _b_a_s_h_(_1_)  under  WWoorrdd  SSpplliittttiinngg,  and  the
+              first word is assigned to the first _n_a_m_e, the second word to the
+              second _n_a_m_e, and so on.  If there are more words than names, the
+              remaining words and their intervening delimiters are assigned to
+              the last _n_a_m_e.  If there are fewer words  read  from  the  input
+              stream  than  names, the remaining names are assigned empty val-
+              ues.  The characters in IIFFSS are used  to  split  the  line  into
+              words  using  the  same  rules the shell uses for expansion (de-
+              scribed in _b_a_s_h_(_1_) under WWoorrdd SSpplliittttiinngg).  The backslash charac-
+              ter  (\\)  may be used to remove any special meaning for the next
+              character read and for line continuation.  Options, if supplied,
+              have the following meanings:
+              --aa _a_n_a_m_e
+                     The words are assigned to sequential indices of the array
+                     variable _a_n_a_m_e, starting at 0.  _a_n_a_m_e is unset before any
+                     new  values  are  assigned.  Other _n_a_m_e arguments are ig-
+                     nored.
+              --dd _d_e_l_i_m
+                     The first character of _d_e_l_i_m is used to terminate the in-
+                     put  line,  rather  than  newline.  If _d_e_l_i_m is the empty
+                     string, rreeaadd will terminate a line when it  reads  a  NUL
+                     character.
+              --ee     If the standard input is coming from a terminal, rreeaaddlliinnee
+                     (see RREEAADDLLIINNEE in _b_a_s_h_(_1_)) is used  to  obtain  the  line.
+                     Readline  uses  the  current (or default, if line editing
+                     was not previously active)  editing  settings,  but  uses
+                     readline's default filename completion.
+              --ii _t_e_x_t
+                     If  rreeaaddlliinnee  is  being  used  to  read the line, _t_e_x_t is
+                     placed into the editing buffer before editing begins.
+              --nn _n_c_h_a_r_s
+                     rreeaadd returns after reading _n_c_h_a_r_s characters rather  than
+                     waiting for a complete line of input, but honors a delim-
+                     iter if fewer than _n_c_h_a_r_s characters are read before  the
+                     delimiter.
+              --NN _n_c_h_a_r_s
+                     rreeaadd  returns  after  reading  exactly  _n_c_h_a_r_s characters
+                     rather than waiting for a complete line of input,  unless
+                     EOF  is encountered or rreeaadd times out.  Delimiter charac-
+                     ters encountered in the input are not  treated  specially
+                     and  do  not cause rreeaadd to return until _n_c_h_a_r_s characters
+                     are read.  The result is not split on the  characters  in
+                     IIFFSS;  the intent is that the variable is assigned exactly
+                     the characters read (with the exception of backslash; see

+              --pp _p_r_o_m_p_t
+                     Display _p_r_o_m_p_t on standard error, without a trailing new-
+                     line, before attempting to read any input.  The prompt is
+                     displayed only if input is coming from a terminal.
+              --rr     Backslash does not act as an escape character.  The back-
+                     slash is considered to be part of the line.  In  particu-
+                     lar,  a  backslash-newline pair may not then be used as a
+                     line continuation.

+                     ters are not echoed.
+              --tt _t_i_m_e_o_u_t
+                     Cause  rreeaadd  to time out and return failure if a complete
+                     line of input (or a specified number  of  characters)  is
+                     not  read within _t_i_m_e_o_u_t seconds.  _t_i_m_e_o_u_t may be a deci-
+                     mal number with a fractional portion following the  deci-
+                     mal  point.   This  option  is  only effective if rreeaadd is
+                     reading input from a terminal,  pipe,  or  other  special
+                     file;  it  has no effect when reading from regular files.
+                     If rreeaadd times out, rreeaadd saves any partial input read into
+                     the  specified  variable _n_a_m_e.  If _t_i_m_e_o_u_t is 0, rreeaadd re-
+                     turns immediately, without trying to read any data.   The
+                     exit  status  is 0 if input is available on the specified
+                     file descriptor, or the read will  return  EOF,  non-zero
+                     otherwise.   The  exit  status is greater than 128 if the
+                     timeout is exceeded.
+              --uu _f_d  Read input from file descriptor _f_d.
+
+              If no _n_a_m_e_s are supplied, the line read, without the ending  de-
+              limiter  but  otherwise  unmodified, is assigned to the variable
+              RREEPPLLYY.  The exit status is zero, unless end-of-file  is  encoun-
+              tered,  rreeaadd times out (in which case the status is greater than
+              128), a variable assignment error (such as assigning to a  read-
+              only variable) occurs, or an invalid file descriptor is supplied
+              as the argument to --uu.
+
+       rreeaaddoonnllyy [--aaAAff] [--pp] [_n_a_m_e[=_w_o_r_d] ...]
+              The given _n_a_m_e_s are marked readonly; the values of  these  _n_a_m_e_s
+              may  not  be changed by subsequent assignment.  If the --ff option
+              is supplied, the functions corresponding to  the  _n_a_m_e_s  are  so
+              marked.   The  --aa  option restricts the variables to indexed ar-
+              rays; the --AA option restricts the variables to  associative  ar-
+              rays.  If both options are supplied, --AA takes precedence.  If no
+              _n_a_m_e arguments are given, or if the --pp  option  is  supplied,  a
+              list of all readonly names is printed.  The other options may be
+              used to restrict the output to a subset of the set  of  readonly
+              names.   The --pp option causes output to be displayed in a format
+              that may be reused as input.  If a variable name is followed  by
+              =_w_o_r_d,  the  value  of  the variable is set to _w_o_r_d.  The return
+              status is 0 unless an invalid option is encountered, one of  the
+              _n_a_m_e_s is not a valid shell variable name, or --ff is supplied with
+              a _n_a_m_e that is not a function.
+
+       rreettuurrnn [_n]
+              Causes a function to stop executing and return the value  speci-
+              fied  by _n to its caller.  If _n is omitted, the return status is
+              that of the last command executed in the function body.  If  rree--
+              ttuurrnn is executed by a trap handler, the last command used to de-
+              termine the status is the last command executed before the  trap
+              handler.   If  rreettuurrnn  is executed during a DDEEBBUUGG trap, the last
+              command used to determine the status is the  last  command  exe-
+              cuted  by the trap handler before rreettuurrnn was invoked.  If rreettuurrnn
+              is used outside a function, but during execution of a script  by
+              the  ..   (ssoouurrccee) command, it causes the shell to stop executing
+              that script and return either _n or the exit status of  the  last
+              command  executed  within  the  script as the exit status of the
+              script.  If _n is supplied, the return value is its least signif-
+              icant  8  bits.  The return status is non-zero if rreettuurrnn is sup-
+              plied a non-numeric argument, or is used outside a function  and
+              not  during  execution  of a script by .. or ssoouurrccee.  Any command
+              associated with the RREETTUURRNN trap is executed before execution re-
+              sumes after the function or script.

+                      If a compound command other than a  subshell  returns  a
+                      non-zero  status  because  a command failed while --ee was
+                      being ignored, the shell does not exit.  A trap on  EERRRR,

+                      applies to the shell environment and each subshell envi-
+                      ronment separately (see CCOOMMMMAANNDD EEXXEECCUUTTIIOONN EENNVVIIRROONNMMEENNTT in

+              --BB      The shell performs brace expansion (see BBrraaccee  EExxppaannssiioonn
+                      in _b_a_s_h_(_1_)).  This is on by default.
+              --CC      If  set,  bbaasshh  does not overwrite an existing file with
+                      the >>, >>&&, and <<>> redirection operators.   This  may  be
+                      overridden when creating output files by using the redi-
+                      rection operator >>|| instead of >>.
+              --EE      If set, any trap on EERRRR is inherited by shell functions,
+                      command  substitutions,  and commands executed in a sub-
+                      shell environment.  The EERRRR trap is normally not  inher-
+                      ited in such cases.
+              --HH      Enable !!  style history substitution.  This option is on
+                      by default when the shell is interactive.
+              --PP      If set, the shell does not resolve symbolic  links  when
+                      executing  commands  such  as ccdd that change the current
+                      working  directory.   It  uses  the  physical  directory
+                      structure instead.  By default, bbaasshh follows the logical
+                      chain of  directories  when  performing  commands  which
+                      change the current directory.
+              --TT      If  set,  any traps on DDEEBBUUGG and RREETTUURRNN are inherited by
+                      shell functions, command substitutions, and commands ex-
+                      ecuted  in a subshell environment.  The DDEEBBUUGG and RREETTUURRNN
+                      traps are normally not inherited in such cases.
+              ----      If no arguments follow this option, then the  positional
+                      parameters are unset.  Otherwise, the positional parame-
+                      ters are set to the _a_r_gs, even if  some  of  them  begin
+                      with a --.

+                      tional parameters remain unchanged.
+
+              The options are off by default unless otherwise noted.  Using  +
+              rather  than  -  causes these options to be turned off.  The op-
+              tions can also be specified as arguments to an invocation of the
+              shell.   The current set of options may be found in $$--.  The re-

+              set.   _n must be a non-negative number less than or equal to $$##.
+              If _n is 0, no parameters are changed.  If _n is not given, it  is
+              assumed to be 1.  If _n is greater than $$##, the positional param-
+              eters are not changed.  The return status is greater  than  zero
+              if _n is greater than $$## or less than zero; otherwise 0.

+       sshhoopptt [--ppqqssuu] [--oo] [_o_p_t_n_a_m_e ...]
+              Toggle  the values of settings controlling optional shell behav-
+              ior.  The settings can be either those listed below, or, if  the
+              --oo option is used, those available with the --oo option to the sseett
+              builtin command.  With no options, or with the --pp option, a list
+              of  all  settable  options  is  displayed, with an indication of
+              whether or not each is set; if _o_p_t_n_a_m_e_s are supplied, the output
+              is  restricted to those options.  The --pp option causes output to
+              be displayed in a form that may be reused as input.   Other  op-
+              tions have the following meanings:
+              --ss     Enable (set) each _o_p_t_n_a_m_e.
+              --uu     Disable (unset) each _o_p_t_n_a_m_e.
+              --qq     Suppresses  normal output (quiet mode); the return status
+                     indicates whether the _o_p_t_n_a_m_e is set or unset.  If multi-
+                     ple  _o_p_t_n_a_m_e arguments are given with --qq, the return sta-
+                     tus is zero if all _o_p_t_n_a_m_e_s are enabled; non-zero  other-
+                     wise.
+              --oo     Restricts  the  values of _o_p_t_n_a_m_e to be those defined for
+                     the --oo option to the sseett builtin.
+
+              If either --ss or --uu is used  with  no  _o_p_t_n_a_m_e  arguments,  sshhoopptt
+              shows  only  those options which are set or unset, respectively.
+              Unless otherwise noted, the sshhoopptt options are  disabled  (unset)
+              by default.
+
+              The  return  status when listing options is zero if all _o_p_t_n_a_m_e_s
+              are enabled, non-zero otherwise.  When setting or unsetting  op-
+              tions,  the  return  status  is  zero unless an _o_p_t_n_a_m_e is not a
+              valid shell option.
+
+              The list of sshhoopptt options is:
+
+              aassssoocc__eexxppaanndd__oonnccee
+                      If set, the shell suppresses multiple evaluation of  as-
+                      sociative  array subscripts during arithmetic expression
+                      evaluation, while executing builtins  that  can  perform
+                      variable  assignments, and while executing builtins that
+                      perform array dereferencing.
+              aauuttooccdd  If set, a command name that is the name of  a  directory
+                      is  executed  as  if it were the argument to the ccdd com-
+                      mand.  This option is only used by interactive shells.
+              ccddaabbllee__vvaarrss
+                      If set, an argument to the ccdd builtin  command  that  is
+                      not  a directory is assumed to be the name of a variable
+                      whose value is the directory to change to.
+              ccddssppeellll If set, minor errors in the spelling of a directory com-
+                      ponent  in  a  ccdd command will be corrected.  The errors
+                      checked for are transposed characters, a missing charac-
+                      ter,  and  one  character  too many.  If a correction is
+                      found, the corrected filename is printed, and  the  com-
+                      mand  proceeds.  This option is only used by interactive
+                      shells.
+              cchheecckkhhaasshh
+                      If set, bbaasshh checks that a command found in the hash ta-
+                      ble  exists  before  trying  to execute it.  If a hashed
+                      command no longer exists, a normal path search  is  per-
+                      formed.
+              cchheecckkjjoobbss
+                      If set, bbaasshh lists the status of any stopped and running
+                      jobs before exiting an interactive shell.  If  any  jobs
+                      are running, this causes the exit to be deferred until a
+                      second exit is attempted without an intervening  command
+                      (see  JJOOBB  CCOONNTTRROOLL  in _b_a_s_h_(_1_)).  The shell always post-
+                      pones exiting if any jobs are stopped.
+              cchheecckkwwiinnssiizzee
+                      If set, bbaasshh checks the window size after each  external
+                      (non-builtin)  command  and,  if  necessary, updates the
+                      values of LLIINNEESS and CCOOLLUUMMNNSS.  This option is enabled  by
+                      default.
+              ccmmddhhiisstt If  set,  bbaasshh attempts to save all lines of a multiple-
+                      line command in the same  history  entry.   This  allows
+                      easy  re-editing of multi-line commands.  This option is
+                      enabled by default, but only has an  effect  if  command
+                      history  is  enabled, as described in _b_a_s_h_(_1_) under HHIISS--
+                      TTOORRYY.

+
+              ccoommpplleettee__ffuullllqquuoottee
+                      If  set,  bbaasshh  quotes all shell metacharacters in file-
+                      names and directory names  when  performing  completion.
+                      If not set, bbaasshh removes metacharacters such as the dol-
+                      lar sign from the set of characters that will be  quoted
+                      in  completed filenames when these metacharacters appear
+                      in shell variable references in words to  be  completed.
+                      This  means that dollar signs in variable names that ex-
+                      pand to directories will not  be  quoted;  however,  any
+                      dollar  signs appearing in filenames will not be quoted,
+                      either.  This is active only when bash  is  using  back-
+                      slashes  to quote completed filenames.  This variable is
+                      set by default, which is the default  bash  behavior  in
+                      versions through 4.2.
+
+              ddiirreexxppaanndd
+                      If  set,  bbaasshh replaces directory names with the results
+                      of word expansion when performing  filename  completion.
+                      This  changes  the contents of the readline editing buf-
+                      fer.  If not set, bbaasshh attempts  to  preserve  what  the
+                      user typed.
+
+              ddiirrssppeellll
+                      If  set,  bbaasshh attempts spelling correction on directory
+                      names during word completion if the directory name  ini-
+                      tially supplied does not exist.
+
+              ddoottgglloobb If  set, bbaasshh includes filenames beginning with a `.' in
+                      the results of pathname expansion.  The filenames  ````..''''
+                      and  ````....''''   must always be matched explicitly, even if
+                      ddoottgglloobb is set.
+
+              eexxeeccffaaiill
+                      If set, a non-interactive shell will not exit if it can-
+                      not  execute  the  file  specified as an argument to the
+                      eexxeecc builtin command.  An  interactive  shell  does  not
+                      exit if eexxeecc fails.
+
+              eexxppaanndd__aalliiaasseess
+                      If set, aliases are expanded as described in _b_a_s_h_(_1_) un-
+                      der AALLIIAASSEESS.  This option is enabled by default for  in-

+                      starts,  identical to the ----ddeebbuuggggeerr option.  If set af-
+                      ter invocation, behavior intended for use  by  debuggers
+                      is enabled:

+                             not executed.
+
+                      33..     If  the  command  run by the DDEEBBUUGG trap returns a

+                             routine  (a shell function or a shell script exe-
+                             cuted by the .. or  ssoouurrccee  builtins),  the  shell
+                             simulates a call to rreettuurrnn.

+                     The expression is false.
+              1 argument
+                     The expression is true if and only if the argument is not
+                     null.
+              2 arguments
+                     If the first argument is !!, the expression is true if and

+                     ment is one of the unary conditional operators listed  in
+                     _b_a_s_h_(_1_)  under CCOONNDDIITTIIOONNAALL EEXXPPRREESSSSIIOONNSS, the expression is
+                     true if the unary test is true.  If the first argument is
+                     not a valid unary conditional operator, the expression is

+                     SSIIOONNSS,  the result of the expression is the result of the
+                     binary test using the first and third arguments as  oper-
+                     ands.   The --aa and --oo operators are considered binary op-
+                     erators when there are three arguments.  If the first ar-
+                     gument  is  !!, the value is the negation of the two-argu-

+                     first argument is exactly (( and the third argument is ex-
+                     actly )), the result is the one-argument test of the  sec-

+              4 arguments
+                     The following conditions are applied in the order listed.
+                     If the first argument is !!, the result is the negation of

+       ttrraapp [--llpp] [[_a_r_g] _s_i_g_s_p_e_c ...]
+              The command _a_r_g is to be read and executed when  the  shell  re-
+              ceives signal(s) _s_i_g_s_p_e_c.  If _a_r_g is absent (and there is a sin-
+              gle _s_i_g_s_p_e_c) or --, each specified signal is reset to its  origi-
+              nal  disposition  (the value it had upon entrance to the shell).
+              If _a_r_g is the null string the signal specified by  each  _s_i_g_s_p_e_c
+              is  ignored by the shell and by the commands it invokes.  If _a_r_g
+              is not present and --pp has been supplied, then the trap  commands
+              associated with each _s_i_g_s_p_e_c are displayed.  If no arguments are
+              supplied or if only --pp is given, ttrraapp prints the  list  of  com-
+              mands  associated  with  each  signal.  The --ll option causes the
+              shell to print a list of signal names  and  their  corresponding
+              numbers.   Each _s_i_g_s_p_e_c is either a signal name defined in <_s_i_g_-
+              _n_a_l_._h>, or a signal number.  Signal names are  case  insensitive
+              and the SSIIGG prefix is optional.
+

+              _b_a_s_h_(_1_)).  Refer to the description of the  eexxttddeebbuugg  option  to
+              the  sshhoopptt  builtin for details of its effect on the DDEEBBUUGG trap.
+              If a _s_i_g_s_p_e_c is RREETTUURRNN, the command _a_r_g is executed each time  a
+              shell  function  or  a  script  executed  with  the  .. or ssoouurrccee
+              builtins finishes executing.
+
+              If a _s_i_g_s_p_e_c is EERRRR, the command  _a_r_g  is  executed  whenever  a
+              pipeline (which may consist of a single simple command), a list,
+              or a compound command returns a non-zero exit status, subject to
+              the  following  conditions.  The EERRRR trap is not executed if the
+              failed command is part of the command list immediately following
+              a  wwhhiillee  or uunnttiill keyword, part of the test in an _i_f statement,
+              part of a command executed in a &&&& or |||| list except the command
+              following  the final &&&& or ||||, any command in a pipeline but the
+              last, or if the command's return value is being  inverted  using
+              !!.  These are the same conditions obeyed by the eerrrreexxiitt (--ee) op-
+              tion.
+
+              Signals ignored upon entry to the shell cannot be trapped or re-

+              their original values in a subshell or subshell environment when
+              one  is  created.   The return status is false if any _s_i_g_s_p_e_c is
+              invalid; otherwise ttrraapp returns true.

+       ttyyppee [--aaffttppPP] _n_a_m_e [_n_a_m_e ...]
+              With no options, indicate how each _n_a_m_e would be interpreted  if
+              used as a command name.  If the --tt option is used, ttyyppee prints a
+              string which is one of _a_l_i_a_s,  _k_e_y_w_o_r_d,  _f_u_n_c_t_i_o_n,  _b_u_i_l_t_i_n,  or
+              _f_i_l_e  if  _n_a_m_e  is  an  alias,  shell  reserved  word, function,
+              builtin, or disk file, respectively.  If the _n_a_m_e is not  found,
+              then  nothing  is  printed,  and  an exit status of false is re-
+              turned.  If the --pp option is used, ttyyppee either returns the  name
+              of  the  disk file that would be executed if _n_a_m_e were specified
+              as a command name, or nothing if ``type -t name'' would not  re-
+              turn  _f_i_l_e.   The  --PP option forces a PPAATTHH search for each _n_a_m_e,
+              even if ``type -t name'' would not return _f_i_l_e.  If a command is
+              hashed, --pp and --PP print the hashed value, which is not necessar-
+              ily the file that appears first in PPAATTHH.  If the  --aa  option  is
+              used,  ttyyppee  prints all of the places that contain an executable
+              named _n_a_m_e.  This includes aliases and functions, if and only if
+              the --pp option is not also used.  The table of hashed commands is
+              not consulted when using --aa.  The  --ff  option  suppresses  shell
+              function lookup, as with the ccoommmmaanndd builtin.  ttyyppee returns true
+              if all of the arguments are found, false if any are not found.

+              The --HH and --SS options specify that the hard or soft limit is set
+              for  the  given resource.  A hard limit cannot be increased by a
+              non-root user once it is set; a soft limit may be  increased  up
+              to  the value of the hard limit.  If neither --HH nor --SS is speci-
+              fied, both the soft and hard limits are set.  The value of _l_i_m_i_t

+              spectively.  If _l_i_m_i_t is omitted, the current value of the  soft

+              When more than one resource is specified,  the  limit  name  and
+              unit,  if  appropriate, are printed before the value.  Other op-

+              new  value  of  the  specified resource.  If no option is given,
+              then --ff is assumed.  Values are in 1024-byte increments,  except

+       uummaasskk [--pp] [--SS] [_m_o_d_e]
+              The user file-creation mask is set to _m_o_d_e.  If _m_o_d_e begins with
+              a  digit,  it is interpreted as an octal number; otherwise it is
+              interpreted as a symbolic mode mask similar to that accepted  by

+              printed.  The --SS option causes the mask to be  printed  in  sym-
+              bolic  form;  the  default output is an octal number.  If the --pp
+              option is supplied, and _m_o_d_e is omitted, the output is in a form
+              that may be reused as input.  The return status is 0 if the mode

+              If the --vv option is given, each _n_a_m_e refers to a shell variable,
+              and  that  variable  is removed.  Read-only variables may not be
+              unset.  If --ff is specified, each _n_a_m_e refers to  a  shell  func-
+              tion,  and the function definition is removed.  If the --nn option
+              is supplied, and _n_a_m_e is a variable with the _n_a_m_e_r_e_f  attribute,
+              _n_a_m_e  will  be unset rather than the variable it references.  --nn

+       wwaaiitt [--ffnn] [--pp _v_a_r_n_a_m_e] [_i_d _._._.]
+              Wait for each specified child process and return its termination
+              status.   Each _i_d may be a process ID or a job specification; if
+              a job spec is given, all processes in that  job's  pipeline  are
+              waited  for.   If  _i_d  is  not given, wwaaiitt waits for all running
+              background jobs and the last-executed process  substitution,  if
+              its process id is the same as $$!!, and the return status is zero.
+              If the --nn option is supplied, wwaaiitt waits for a single  job  from
+              the list of _i_ds or, if no _i_ds are supplied, any job, to complete
+              and returns its exit status.  If none of the supplied  arguments
+              is a child of the shell, or if no arguments are supplied and the
+              shell has no unwaited-for children, the exit status is 127.   If
+              the  --pp option is supplied, the process or job identifier of the
+              job for which the exit status is returned  is  assigned  to  the
+              variable  _v_a_r_n_a_m_e  named  by  the option argument.  The variable
+              will be unset initially, before any assignment.  This is  useful
+              only  when  the --nn option is supplied.  Supplying the --ff option,
+              when job control is enabled, forces wwaaiitt to wait for _i_d to  ter-
+              minate before returning its status, instead of returning when it
+              changes status.  If _i_d specifies a non-existent process or  job,
+              the  return  status is 127.  If wwaaiitt is interrupted by a signal,
+              the return status will be greater than 128, as  described  under
+              SSIIGGNNAALLSS  in  _b_a_s_h_(_1_).   Otherwise, the return status is the exit
+              status of the last process or job waited for.

+SSHHEELLLL CCOOMMPPAATTIIBBIILLIITTYY MMOODDEE
+       Bash-4.0 introduced the concept of a _s_h_e_l_l _c_o_m_p_a_t_i_b_i_l_i_t_y _l_e_v_e_l,  speci-
+       fied  as  a  set  of options to the shopt builtin ( ccoommppaatt3311, ccoommppaatt3322,
+       ccoommppaatt4400, ccoommppaatt4411, and so on).  There is only one current  compatibil-
+       ity  level  --  each  option  is mutually exclusive.  The compatibility
+       level is intended to allow users to select behavior from previous  ver-
+       sions  that  is  incompatible  with  newer  versions while they migrate
+       scripts to use current features and behavior. It's  intended  to  be  a
+       temporary solution.
+
+       This  section does not mention behavior that is standard for a particu-
+       lar version (e.g., setting ccoommppaatt3322 means that quoting the rhs  of  the
+       regexp  matching operator quotes special regexp characters in the word,
+       which is default behavior in bash-3.2 and subsequent versions).
+
+       If a user enables, say, ccoommppaatt3322, it may affect the behavior  of  other
+       compatibility  levels  up  to  and  including the current compatibility
+       level.  The idea is that each  compatibility  level  controls  behavior
+       that  changed  in that version of bbaasshh, but that behavior may have been
+       present in earlier versions.  For instance, the change to  use  locale-
+       based  comparisons  with  the  [[[[ command came in bash-4.1, and earlier
+       versions used ASCII-based comparisons, so enabling ccoommppaatt3322 will enable
+       ASCII-based  comparisons  as  well.  That granularity may not be suffi-
+       cient for all uses, and as a result users should  employ  compatibility
+       levels  carefully.   Read the documentation for a particular feature to
+       find out the current behavior.
+
+       Bash-4.3 introduced a new shell variable: BBAASSHH__CCOOMMPPAATT.  The  value  as-
+       signed to this variable (a decimal version number like 4.2, or an inte-
+       ger corresponding to the ccoommppaatt_N_N option, like 42) determines the  com-
+       patibility level.
+
+       Starting  with bash-4.4, Bash has begun deprecating older compatibility
+       levels.  Eventually, the options will be removed in favor of  BBAASSHH__CCOOMM--
+       PPAATT.
+
+       Bash-5.0  is  the  final  version for which there will be an individual
+       shopt option for the previous version. Users should use BBAASSHH__CCOOMMPPAATT  on
+       bash-5.0 and later versions.
+
+       The  following  table describes the behavior changes controlled by each
+       compatibility level setting.  The ccoommppaatt_N_N tag is used as shorthand for
+       setting the compatibility level to _N_N using one of the following mecha-
+       nisms.  For versions prior to bash-5.0, the compatibility level may  be
+       set  using  the  corresponding ccoommppaatt_N_N shopt option.  For bash-4.3 and
+       later versions, the BBAASSHH__CCOOMMPPAATT variable is preferred, and  it  is  re-
+       quired for bash-5.1 and later versions.

+                     ceived  the  interrupt,  so interrupting one command in a

+                     lation  and _s_t_r_c_m_p(3); bash-4.1 and later use the current

+                     that  cause  the  current  command to fail, even in posix
+                     mode (the default behavior is to make them  fatal  errors
+                     that cause the shell to exit)
+              +o      when   executing   a   shell  function,  the  loop  state
+                     (while/until/etc.)  is not reset, so bbrreeaakk or ccoonnttiinnuuee in
+                     that function will break or continue loops in the calling
+                     context. Bash-4.4 and later reset the loop state to  pre-
+                     vent this
+
+       ccoommppaatt4444
+              +o      the  shell  sets  up  the  values  used  by BBAASSHH__AARRGGVV and
+                     BBAASSHH__AARRGGCC so they can expand to  the  shell's  positional
+                     parameters even if extended debugging mode is not enabled
+              +o      a  subshell  inherits  loops  from its parent context, so
+                     bbrreeaakk or  ccoonnttiinnuuee  will  cause  the  subshell  to  exit.
+                     Bash-5.0  and  later  reset the loop state to prevent the
+                     exit
+              +o      variable assignments preceding builtins like  eexxppoorrtt  and
+                     rreeaaddoonnllyy that set attributes continue to affect variables
+                     with the same name in the calling environment even if the
+                     shell is not in posix mode
+
+       ccoommppaatt5500
+              +o      Bash-5.1  changed  the way $$RRAANNDDOOMM is generated to intro-
+                     duce slightly more randomness. If the shell compatibility
+                     level  is  set  to  50 or lower, it reverts to the method
+                     from bash-5.0 and previous versions, so seeding the  ran-
+                     dom  number generator by assigning a value to RRAANNDDOOMM will
+                     produce the same sequence as in bash-5.0
+              +o      If the command hash table is empty, bash  versions  prior
+                     to  bash-5.1 printed an informational message to that ef-
+                     fect, even when producing output that can  be  reused  as
+                     input.  Bash-5.1  suppresses that message when the --ll op-
+                     tion is supplied.
+
+       ccoommppaatt5511
+              +o      The uunnsseett builtin treats attempts  to  unset  array  sub-
+                     scripts  @@ and ** differently depending on whether the ar-
+                     ray is indexed or associative, and  differently  than  in
+                     previous versions.

+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document @dfn{free} in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License.  Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein.  The ``Document'', below,
+refers to any such manual or work.  Any member of the public is a
+licensee, and is addressed as ``you''.  You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject.  (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.  If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant.  The Document may contain zero
+Invariant Sections.  If the Document does not identify any Invariant
+Sections then there are none.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.  A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text.  A copy that is not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+@sc{ascii} without markup, Texinfo input format, La@TeX{} input
+format, @acronym{SGML} or @acronym{XML} using a publicly available
+@acronym{DTD}, and standard-conforming simple @acronym{HTML},
+PostScript or @acronym{PDF} designed for human modification.  Examples
+of transparent image formats include @acronym{PNG}, @acronym{XCF} and
+@acronym{JPG}.  Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, @acronym{SGML} or
+@acronym{XML} for which the @acronym{DTD} and/or processing tools are
+not generally available, and the machine-generated @acronym{HTML},
+PostScript or @acronym{PDF} produced by some word processors for
+output purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+The ``publisher'' means any person or entity that distributes copies
+of the Document to the public.
+
+A section ``Entitled XYZ'' means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language.  (Here XYZ stands for a
+specific section name mentioned below, such as ``Acknowledgements'',
+``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
+of such a section when you modify the Document means that it remains a
+section ``Entitled XYZ'' according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document.  These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License.  You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute.  However, you may accept
+compensation in exchange for copies.  If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover.  Both covers must also clearly and legibly identify
+you as the publisher of these copies.  The front cover must present
+the full title with all words of the title equally prominent and
+visible.  You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.

+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it.  In addition, you must do these things in the Modified Version:
+
+@enumerate A
+@item
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document).  You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+@item
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+@item
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+@item
+Preserve all the copyright notices of the Document.
+
+@item
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+@item
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+@item
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+@item
+Include an unaltered copy of this License.
+
+@item
+Preserve the section Entitled ``History'', Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page.  If
+there is no section Entitled ``History'' in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+@item
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on.  These may be placed in the ``History'' section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+@item
+For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+
+@item
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles.  Section numbers
+or the equivalent are not considered part of the section titles.
+
+@item
+Delete any section Entitled ``Endorsements''.  Such a section
+may not be included in the Modified Version.
+
+@item
+Do not retitle any existing section to be Entitled ``Endorsements'' or
+to conflict in title with any Invariant Section.
+
+@item
+Preserve any Warranty Disclaimers.
+@end enumerate
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant.  To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties---for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version.  Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity.  If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+@item
+COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy.  If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled ``History''
+in the various original documents, forming one section Entitled
+``History''; likewise combine any sections Entitled ``Acknowledgements'',
+and any sections Entitled ``Dedications''.  You must delete all
+sections Entitled ``Endorsements.''
+
+@item
+COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+@item
+AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an ``aggregate'' if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+@item
+TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections.  You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers.  In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled ``Acknowledgements'',
+``Dedications'', or ``History'', the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+@item
+TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+
+@item
+FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time.  Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.  See
+@uref{http://www.gnu.org/copyleft/}.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License ``or any later version'' applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation.  If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.  If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.

+@item
+RELICENSING
+
+``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works.  A
+public wiki that anybody can edit is an example of such a server.  A
+``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the
+site means any set of copyrightable works thus published on the MMC
+site.
+
+``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0
+license published by Creative Commons Corporation, a not-for-profit
+corporation with a principal place of business in San Francisco,
+California, as well as future copyleft versions of that license
+published by that same organization.
+
+``Incorporate'' means to publish or republish a Document, in whole or
+in part, as part of another Document.
+
+An MMC is ``eligible for relicensing'' if it is licensed under this
+License, and if all works that were first published under this License
+somewhere other than this MMC, and subsequently incorporated in whole
+or in part into the MMC, (1) had no cover texts or invariant sections,
+and (2) were thus incorporated prior to November 1, 2008.
+
+The operator of an MMC Site may republish an MMC contained in the site
+under CC-BY-SA on the same site at any time before August 1, 2009,
+provided the MMC is eligible for relicensing.

+@heading ADDENDUM: How to use this License for your documents
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+@smallexample
+@group
+  Copyright (C)  @var{year}  @var{your name}.
+  Permission is granted to copy, distribute and/or modify this document
+  under the terms of the GNU Free Documentation License, Version 1.3
+  or any later version published by the Free Software Foundation;
+  with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+  Texts.  A copy of the license is included in the section entitled ``GNU
+  Free Documentation License''.
+@end group
+@end smallexample
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the ``with@dots{}Texts.'' line with this:

+
+
+ Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
+     <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+0. PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document "free" in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of "copyleft", which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+
+
+1. APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License.  Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein.  The "Document", below,
+refers to any such manual or work.  Any member of the public is a
+licensee, and is addressed as "you".  You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A "Modified Version" of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A "Secondary Section" is a named appendix or a front-matter section of
+the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject.  (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The "Invariant Sections" are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.  If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant.  The Document may contain zero
+Invariant Sections.  If the Document does not identify any Invariant
+Sections then there are none.
+
+The "Cover Texts" are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.  A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A "Transparent" copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text.  A copy that is not "Transparent" is called "Opaque".
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input format, SGML
+or XML using a publicly available DTD, and standard-conforming simple
+HTML, PostScript or PDF designed for human modification.  Examples of
+transparent image formats include PNG, XCF and JPG.  Opaque formats
+include proprietary formats that can be read and edited only by
+proprietary word processors, SGML or XML for which the DTD and/or
+processing tools are not generally available, and the
+machine-generated HTML, PostScript or PDF produced by some word
+processors for output purposes only.
+
+The "Title Page" means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+The "publisher" means any person or entity that distributes copies of
+the Document to the public.
+
+A section "Entitled XYZ" means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language.  (Here XYZ stands for a
+specific section name mentioned below, such as "Acknowledgements",
+"Dedications", "Endorsements", or "History".)  To "Preserve the Title"
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document.  These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+2. VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no
+other conditions whatsoever to those of this License.  You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute.  However, you may accept
+compensation in exchange for copies.  If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+3. COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover.  Both covers must also clearly and legibly identify
+you as the publisher of these copies.  The front cover must present
+the full title with all words of the title equally prominent and
+visible.  You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to
+give them a chance to provide you with an updated version of the
+Document.
+
+
+4. MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it.  In addition, you must do these things in the Modified Version:
+
+A. Use in the Title Page (and on the covers, if any) a title distinct
+   from that of the Document, and from those of previous versions
+   (which should, if there were any, be listed in the History section
+   of the Document).  You may use the same title as a previous version
+   if the original publisher of that version gives permission.
+B. List on the Title Page, as authors, one or more persons or entities
+   responsible for authorship of the modifications in the Modified
+   Version, together with at least five of the principal authors of the
+   Document (all of its principal authors, if it has fewer than five),
+   unless they release you from this requirement.
+C. State on the Title page the name of the publisher of the
+   Modified Version, as the publisher.
+D. Preserve all the copyright notices of the Document.
+E. Add an appropriate copyright notice for your modifications
+   adjacent to the other copyright notices.
+F. Include, immediately after the copyright notices, a license notice
+   giving the public permission to use the Modified Version under the
+   terms of this License, in the form shown in the Addendum below.
+G. Preserve in that license notice the full lists of Invariant Sections
+   and required Cover Texts given in the Document's license notice.
+H. Include an unaltered copy of this License.
+I. Preserve the section Entitled "History", Preserve its Title, and add
+   to it an item stating at least the title, year, new authors, and
+   publisher of the Modified Version as given on the Title Page.  If
+   there is no section Entitled "History" in the Document, create one
+   stating the title, year, authors, and publisher of the Document as
+   given on its Title Page, then add an item describing the Modified
+   Version as stated in the previous sentence.
+J. Preserve the network location, if any, given in the Document for
+   public access to a Transparent copy of the Document, and likewise
+   the network locations given in the Document for previous versions
+   it was based on.  These may be placed in the "History" section.
+   You may omit a network location for a work that was published at
+   least four years before the Document itself, or if the original
+   publisher of the version it refers to gives permission.
+K. For any section Entitled "Acknowledgements" or "Dedications",
+   Preserve the Title of the section, and preserve in the section all
+   the substance and tone of each of the contributor acknowledgements
+   and/or dedications given therein.
+L. Preserve all the Invariant Sections of the Document,
+   unaltered in their text and in their titles.  Section numbers
+   or the equivalent are not considered part of the section titles.
+M. Delete any section Entitled "Endorsements".  Such a section
+   may not be included in the Modified Version.
+N. Do not retitle any existing section to be Entitled "Endorsements"
+   or to conflict in title with any Invariant Section.
+O. Preserve any Warranty Disclaimers.
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant.  To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version.  Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity.  If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+
+5. COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy.  If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications".  You must delete all sections
+Entitled "Endorsements".
+
+
+6. COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other
+documents released under this License, and replace the individual
+copies of this License in the various documents with a single copy
+that is included in the collection, provided that you follow the rules
+of this License for verbatim copying of each of the documents in all
+other respects.
+
+You may extract a single document from such a collection, and
+distribute it individually under this License, provided you insert a
+copy of this License into the extracted document, and follow this
+License in all other respects regarding verbatim copying of that
+document.
+
+
+7. AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+
+8. TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections.  You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers.  In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+
+9. TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+
+
+10. FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions of the
+GNU Free Documentation License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in
+detail to address new problems or concerns.  See
+http://www.gnu.org/copyleft/.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation.  If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.  If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.
+
+11. RELICENSING
+
+"Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works.  A
+public wiki that anybody can edit is an example of such a server.  A
+"Massive Multiauthor Collaboration" (or "MMC") contained in the site
+means any set of copyrightable works thus published on the MMC site.
+
+"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 
+license published by Creative Commons Corporation, a not-for-profit 
+corporation with a principal place of business in San Francisco, 
+California, as well as future copyleft versions of that license 
+published by that same organization.
+
+"Incorporate" means to publish or republish a Document, in whole or in 
+part, as part of another Document.
+
+An MMC is "eligible for relicensing" if it is licensed under this 
+License, and if all works that were first published under this License 
+somewhere other than this MMC, and subsequently incorporated in whole or 
+in part into the MMC, (1) had no cover texts or invariant sections, and 
+(2) were thus incorporated prior to November 1, 2008.
+
+The operator of an MMC Site may republish an MMC contained in the site
+under CC-BY-SA on the same site at any time before August 1, 2009,
+provided the MMC is eligible for relicensing.
+
+
+ADDENDUM: How to use this License for your documents
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+    Copyright (c)  YEAR  YOUR NAME.
+    Permission is granted to copy, distribute and/or modify this document
+    under the terms of the GNU Free Documentation License, Version 1.3
+    or any later version published by the Free Software Foundation;
+    with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
+    A copy of the license is included in the section entitled "GNU
+    Free Documentation License".
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the "with...Texts." line with this:
+
+    with the Invariant Sections being LIST THEIR TITLES, with the
+    Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

+
+RREESSTTRRIICCTTEEDD SSHHEELLLL
+       If bbaasshh is started with the name rrbbaasshh, or the --rr option is supplied at
+       invocation, the shell becomes restricted.  A restricted shell  is  used
+       to  set  up an environment more controlled than the standard shell.  It
+       behaves identically to bbaasshh with the exception that the  following  are
+       disallowed or not performed:
+
+       +o      changing directories with ccdd
+
+       +o      setting  or  unsetting the values of SSHHEELLLL, PPAATTHH, HHIISSTTFFIILLEE, EENNVV,
+              or BBAASSHH__EENNVV
+
+       +o      specifying command names containing //
+
+       +o      specifying a filename containing a // as an  argument  to  the  ..
+              builtin command
+
+       +o      specifying  a  filename containing a slash as an argument to the
+              hhiissttoorryy builtin command
+
+       +o      specifying a filename containing a slash as an argument  to  the
+              --pp option to the hhaasshh builtin command
+
+       +o      importing  function  definitions  from  the shell environment at
+              startup
+
+       +o      parsing the value of SSHHEELLLLOOPPTTSS from  the  shell  environment  at
+              startup
+
+       +o      redirecting output using the >, >|, <>, >&, &>, and >> redirect-
+              ion operators
+
+       +o      using the eexxeecc builtin command to replace the shell with another
+              command
+
+       +o      adding  or  deleting builtin commands with the --ff and --dd options
+              to the eennaabbllee builtin command
+
+       +o      using the  eennaabbllee  builtin  command  to  enable  disabled  shell
+              builtins
+
+       +o      specifying the --pp option to the ccoommmmaanndd builtin command
+
+       +o      turning  off  restricted  mode  with  sseett  ++rr  or  sshhoopptt  --uu rree--
+              ssttrriicctteedd__sshheellll.
+
+       These restrictions are enforced after any startup files are read.
+
+       When a command that is found to be a shell script  is  executed,  rrbbaasshh
+       turns off any restrictions in the shell spawned to execute the script.

+% Please try the latest version of texinfo.tex before submitting bug

+%   http://ftpmirror.gnu.org/texinfo/ (same, via a mirror), or

+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution.  For a simple
+% manual foo.texi, however, you can get away with this:
+%   tex foo.texi
+%   texindex foo.??
+%   tex foo.texi
+%   tex foo.texi
+%   dvips foo.dvi -o  # or whatever; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages, to some
+% extent.  You can get the existing language-specific files from the
+% full Texinfo distribution.

+% Output a mark which sets \thischapter, \thissection and \thiscolor.

+%
+% A mark contains a subexpression of the \ifcase ... \fi construct.

+%
+% Another complication is to let the user choose whether \thischapter

+% described on page 260 of The TeXbook.  It involves outputting two

+% can fit this many characters:
+%   8.5x11=86   smallbook=72  a4=90  a5=69
+% If we use \scriptfonts (8pt), then we can fit this many characters:
+%   8.5x11=90+  smallbook=80  a4=90+  a5=77
+% For me, subjectively, the few extra characters that fit aren't worth
+% the additional smallness of 8pt.  So I'm making the default 9pt.
+%
+% By the way, for comparison, here's what fits with @example (10pt):

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble.  Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+%   @multitable @columnfractions .25 .3 .45
+%   @item ...
+%
+%   Numbers following @columnfractions are the percent of the total
+%   current hsize to be used for each column. You may use as many
+%   columns as desired.
+
+
+% Or use a template:
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item ...
+%   using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item first col stuff @tab second col stuff @tab third col
+%   @item
+%   first col stuff
+%   @tab
+%   second col stuff
+%   @tab
+%   third col
+%   @item first col stuff @tab second col stuff
+%   @tab Many paragraphs of text may be used in any column.
+%
+%         They will wrap at the width determined by the template.
+%   @item@tab@tab This will be in third column.
+%   @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+%                                                            to baseline.

+# arrayops.bash --- hide some of the nasty syntax for manipulating bash arrays
+# Author: Noah Friedman <friedman@splode.com>
+# Created: 2016-07-08

+
+# Commentary:
+
+# These functions try to tame the syntactic nightmare that is bash array
+# syntax, which makes perl's almost look reasonable.
+#
+# For example the apush function below lets you write:
+#
+#	apush arrayvar newval
+#
+# instead of
+#
+#	${arrayvar[${#arrayvar[@]}]}=newval
+#
+# Because seriously, you've got to be kidding me.
+
+# These functions avoid the use of local variables as much as possible
+# (especially wherever modification occurs) because those variable names
+# might shadow the array name passed in.  Dynamic scope!
+
+# Code:
+
+#:docstring apush:
+# Usage: apush arrayname val1 {val2 {...}}
+#
+# Appends VAL1 and any remaining arguments to the end of the array
+# ARRAYNAME as new elements.
+#:end docstring:
+apush()
+{
+    eval "$1=(\"\${$1[@]}\" \"\${@:2}\")"
+}
+
+#:docstring apop:
+# Usage: apop arrayname {n}
+#
+# Removes the last element from ARRAYNAME.
+# Optional argument N means remove the last N elements.
+#:end docstring:
+apop()
+{
+    eval "$1=(\"\${$1[@]:0:\${#$1[@]}-${2-1}}\")"
+}
+

+# The psuedo-ksh autoloader.
+
+# How to use:
+# o One function per file.
+# o File and function name match exactly.
+# o File is located in a directory that is in FPATH.
+# o This script (autoload) must be sourced in as early as possible. This
+#   implies that any code in this script should NOT rely on any library of local
+#   or self-defined functions having already been loaded.
+# o autoload must be called for each function before the function can be used. If
+#   autoloads are in directories where there are nothing but autoloads, then
+#   'autoload /path/to/files/*' suffices (but see options -a and -f).
+# o The call must be made in the current environment, not a subshell.
+# o The command line suffices as "current environment". If you have autoload
+#   calls in a script, that script must be dotted into the process.

+SYNOPSIS
+        autoload [-ps]
+        autoload [-xuremloyv] [function ...]
+        autoload -a directory [-oyv]
+        autoload -f [-oyv]
+        autoload [-h]
+
+        autoreload [function ...]
+
+DESCRIPTION
+
+        An implementation of the 'autoload' functionality built into other
+        shells, of which 'ksh' is the most prominent.  It allows for a keeping
+        the process environment small by loading small 'shim' functions into
+        memory that will, on first call, load the full text of the given
+        function and run it. Subsequent calls to the function just run the
+        function.
+
+        'autoreload' is a synonym for 'autoload -r'. See below.
+
+USAGE
+
+        o Each function to be autoloaded should be defined in a single file,
+          named exactly the same as the function.
+
+        o In order to avoid side effects, do NOT put code other than the
+          function definition in the file. Unless of course you want to do some
+          one-time initialization. But beware that if you reload the function
+          for any reason, you will rerun the initialization code. Make sure
+          your initialization is re-entrant. Or, better yet,
+
+          *** do NOT put code other than the function definition in the file ***
+
+        o These function definition files should be placed in a directory that
+          is in the FPATH environment variable. Subdirectories are NOT scanned.
+
+        o The autoload script should be sourced into the current process as
+          early as possible in process start up. See NOTES below for
+          suggestions.
+
+        o The calls to the autoload function must be made in the current
+          process. If your calls are in their own script, that script must be
+          sourced in. Command line invocations are also sufficient. (But see
+          '-l' below.)
+
+        o The first time the function is called, the shim function that was
+          created by the 'autoload' call is what is executed. This function
+          then goes and finds the appropriate file in FPATH, sources it in and
+          then calls the actual function with any arguments you just passed in
+          to the shim function. Subsequent calls just run the function.
+
+OPTIONS
+
+        -a Autoload (a)ll the functions found in the given directory.
+
+        -f Autoload all the functions found in all the directories on the
+           FPATH.
+
+        -p Print all the autoloaded functions.
+
+        -s Print all the autoloaded functions and add their export status.
+
+        -x Export the specified functions to the environment for use in
+           subshells.
+
+        -u Unset the function, so it can be reloaded.
+
+        -r Reload the shims of the specified functions, even if the functions
+           have been already been executed.  This will allow you to modify the
+           functions' source and have the new version executed next time the
+           function is called.
+
+           It would be very easy to modify a function's script, run the
+           function and scratch your head for a long time trying to figure out
+           why your changes are not being executed. That's why we provide the
+           '-e' flag described below for modifications.
+
+           Reloads, of course, only apply in the context of the current session
+           and any future subshell you start from the current session. Existing
+           sessions will need to have the same 'autoload -r' command run in
+           them.
+
+        -e Find the scripts in which the specified functions are defined and
+           start up \$EDITOR on those scripts. Reload the ones that were
+           modified when you exit \$EDITOR. (Note: If you use 'autoload -e foo'
+           to edit function 'foo', and then in your editor you separately load
+           up function 'bar', 'autoload' has no way of knowing that you edited
+           'bar' and will NOT reload 'bar' for you.)
+
+           Reloads, of course, only apply in the context of the current session
+           and any future subshell you start from the current session. Existing
+           sessions will need to have the same 'autoload -r' command run in
+           them.
+
+        -m Find the scripts in which the specified functions are defined and
+           run \$PAGER on them ('m' is for 'more', because 'p' (page) and 'l'
+           (load) are already used as options in 'autoload').
+
+        -l When autoloading a function, eval the shim immediately in order to
+           load the true function code. See "Using '-l'" in the NOTES below for
+           details.
+
+        -o Optimize. When autoloading, take the time to execute
+
+               'theCharCount=\$(wc -c \$theFuncFile)'
+
+           for each function and
+
+                if \$theCharCount < \$AUTOLOAD_SHIM_OVERHEAD
+
+           don't shim it, just eval directly.
+
+        -y Summar(y). Print the number of loaded, exported and optimized
+           functions.
+
+        -v Turns up the chattiness.
+
+NOTES
+
+        o Calling 'autoload' on a function that already exists (either shimmed
+          or expanded) silently ignores the request to load the shim unless it
+          has been previously removed (-u) or you force the reload (-r).
+
+        o Changing and reloading a function that has been exported does not
+          require it be re-exported; the modifications will appear in
+          subsequent subshells.
+
+        o Using '-1'
+
+          If you are running under set -x and/or set -v, you may see that the
+          shim does not appear to "work"; instead of seeing the shim first and
+          the real code subsequently, you may see the shim evaluated multiple
+          times.
+
+          This may not be an error; review your code. What is most likely
+          happening is that you are calling the function in subshells via
+          backticks or $(), or in a script that is not being sourced into the
+          current environment. If you have not previously called the function
+          in question at your command line or in a script that was sourced into
+          the current environment, then the various subshells are going to
+          encounter the shim and replace with the real code before executing.
+
+          Remember, however, that environment modifications that occur in a
+          subshell are NOT propagated back to the calling shell or over to any
+          sibling shells. So, if you call an autoloaded function in a very
+          tight loop of very many subshells, you may want to make an 'autoload
+          -l' call before you start your loop. '-l' will instruct 'autoload' to
+          bypass the shim creation and just source in the function's file
+          directly. For a few calls, the overhead of repeatedly running the
+          shim is not expensive, but in a tight loop, it might be. Caveat
+          Programmer.
+
+        o Although the number of functions in the environment does not change
+          by using 'autoload', the amount of memory they take up can be greatly
+          reduced, depending on the size of your functions. If you have a lot
+          of small functions, then it is possible that the shim text will be
+          larger than your actual functions, rendering the memory savings moot.
+
+          'small' in this case can be determined by calling the function
+          'autoload_calc_shimsize' with the name of the function to determine
+          its shim size.
+
+        o In order to support the -p and -s options, we need a way to determine
+          if a function 'func' has been autoloaded or if it was loaded
+          diredctly. In order to do that, we modify the function's code by
+          adding the text
+
+              local  AUTOLOADED='func';
+
+          to the shim and to the actual function text, just after the opening
+          brace. Then supporting -p and -s is just a matter of grepping through
+          all the function text in memory. Even though grepping through the
+          environment may not be the most efficient way to support this, it is
+          the simplest to implement for -p and -s operations that are not
+          heavily used.
+
+          As a consequence of this (and other reasons), the AUTOLOAD* namespace
+          is reserved for autoloading. Make sure you check any functions that
+          you bring under autoload for use of variables or functions that start
+          with AUTOLOAD and change them.
+
+        o The easiest way to load shims for all functions on the FPATH is to run
+
+               autoload -f -x
+
+          in the profile that gets run for login shells.
+
+          When called in the profile of a login shell where no definitions
+          exist, -f will load all functions it can find on FPATH and -x will
+          export all of those functions to be available in subshells when this
+          is called in a login shell. Using this option will relieve you of the
+          need to call 'autoload' after Every Single Function Definition, nor
+          will you need to call it in subshells.
+
+          The only thing left to do is to load up the autoload function itself
+          and its helper functions. That needs to happen in your profile:
+
+            export FPATH=~/functions       # or wherever you stash them
+            if [ -z $(declare -F autoload) ]
+            then
+              . ~/bin/autoload             # or wherever you've put it
+            fi
+
+          The 'if' statement is used to make sure we don't reload autoload
+          needlessly. Sourcing in the autoload script loads the 'autoload'
+          function and all of its support functions. Additionally, we export
+          all of these functions so that they are available in subshells; you
+          do not have to re-source the autoload file in '.bashrc'.
+
+        o Even with all of these shenanigans, you will find cases where no
+          matter how hard you try, your autoloaded functions will be
+          unavailable to you, even if you run 'autoload -x -f'. The typical
+          condition for this is starting up not a subshell, but a brand new
+          DIFFERENT shell. And the typical example of this is git extensions.
+
+          At the time of this writing, git extensions work by taking a command
+          'git foo' and looking for a file 'git-foo' on the path. 'git' then
+          executes 'git-foo' in a new shell - it executes your command in
+          /bin/sh. That's not a subshell of your process. It will not get your
+          exported shell functions. Ballgame over.
+
+          If you find that you want your functions to be available in such
+          circumstances, convert them back to plain old scripts, make sure they
+          are 'sh' compliant and take the read/parse hit every time they are
+          run.

+Some examples of ready-to-dynamic-load builtins.  Most of the
+examples given are reimplementations of standard commands whose
+execution time is dominated by process startup time.  Some
+exceptions are sleep, which allows you to sleep for fractions
+of a second, finfo, which provides access to the rest of the
+elements of the `stat' structure that `test' doesn't let you
+see, csv, which allows you to manipulate data from comma-separated
+values files, fdflags, which lets you change the flags associated
+with one of the shell's file descriptors, and pushd/popd/dirs, which
+allows you to compile them out of the shell.
+
+All of the new builtins in ksh93 that bash didn't already have
+are included here, as is the ksh `print' builtin.
+
+The configure script in the top-level source directory uses the
+support/shobj-conf script to set the right values in the Makefile,
+so you should not need to change the Makefile.  If your system
+is not supported by support/shobj-conf, and it has the necessary
+facilities for building shared objects and support for the
+dlopen/dlsyn/dlclose/dlerror family of functions, please make
+the necessary changes to support/shobj-conf and send the changes
+to bash-maintainers@gnu.org.
+
+Loadable builtins are loaded into a running shell with
+
+	enable -f filename builtin-name
+
+enable uses a simple reference-counting scheme to avoid unloading a
+shared object that implements more than one loadable builtin before
+all loadable builtins implemented in the object are removed.
+
+Many of the details needed by builtin writers are found in hello.c,
+the canonical example.  There is no real `builtin writers' programming
+guide'.  The file template.c provides a template to use for creating
+new loadable builtins.
+
+The file "Makefile.inc" is created using the same values that configure
+writes into Makefile.in, and is installed in the same directory as the
+rest of the example builtins. It's intended to be a start at something
+that can be modified or included to help you build your own loadables
+without having to search for the right CFLAGS and LDFLAGS.
+
+basename.c	Return non-directory portion of pathname.
+cat.c		cat(1) replacement with no options - the way cat was intended.
+csv.c		Process a line of csv data and store it in an indexed array.

+Makefile.in	Simple makefile for the sample loadable builtins.
+Makefile.inc.in	Sample makefile to use for loadable builtin development.
+mkdir.c		Make directories.
+mkfifo.c	Create named pipes.
+mktemp.c	Make unique temporary file name.
+mypid.c		Add $MYPID variable, demonstrate use of unload hook function.
+necho.c		echo without options or argument interpretation.
+pathchk.c	Check pathnames for validity and portability.
+print.c		Loadable ksh-93 style print builtin.
+printenv.c	Minimal builtin clone of BSD printenv(1).
+push.c		Anyone remember TOPS-20?
+realpath.c	Canonicalize pathnames, resolving symlinks.
+rm.c		Remove files and directories.
+rmdir.c		Remove directory.
+seq.c		Print a sequence of decimal or floating point numbers.
+setpgid.c	Set a process's pgrp; example of how to wrap a system call.
+sleep.c		sleep for fractions of a second.
+stat.c		populate an associative array with information about a file
+strftime.c	Loadable builtin interface to strftime(3).
+sync.c		Sync the disks by forcing pending filesystem writes to complete.
+tee.c		Duplicate standard input.
+template.c	Example template for loadable builtin.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR

+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>

+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it

+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.

+# Shellmath
+Introducing decimal arithmetic libraries for the Bash shell, because
+they said it couldn't be done... and because:
+
+.
+
+![image info](./image.png)
+
+## Quick-start guide
+Download this project and source the file `shellmath.sh` into your shell script,
+then fire away at the shellmath API!
+
+The ___basic___ API looks like this:
+```
+    _shellmath_add        arg1   arg2  [...]  argN
+    _shellmath_subtract   arg1   arg2               # means arg1 - arg2
+    _shellmath_multiply   arg1   arg2  [...]  argN
+    _shellmath_divide     arg1   arg2               # means arg1 / arg2
+```
+
+The ___extended___ API introduces one more function:
+```
+    _shellmath_getReturnValue   arg
+```
+
+This function optimizes away the need for ___$(___ subshelling ___)___ in order to capture `shellmath`'s output.
+To use this feature, just be sure to set `__shellmath_isOptimized=1` at the top
+of your script. (You can find an example in `faster_e_demo.sh`.)
+
+Operands to the _shellmath_ functions can be integers or decimal
+numbers presented in either standard or scientific notation:
+```
+    _shellmath_add   1.009   4.223e-2
+    _shellmath_getReturnValue   sum
+    echo "The sum is $sum"
+```
+Addition and multiplication are of arbitrary arity; try this on for size:
+```
+    _shellmath_multiply  1  2  3  4  5  6
+    _shellmath_getReturnValue   sixFactorial
+    echo "6 factorial is $sixFactorial"
+```
+Subtraction and division, OTOH, are exclusively binary operations. 
+
+## The demos
+For a gentle introduction to `shellmath` run the demo `slower_e_demo.sh` 
+with a small whole-number argument, say 15:
+```
+$ slower_e_demo.sh 15
+e = 2.7182818284589936
+```
+
+This script uses a few `shellmath` API calls to calculate *e*, the mathematical
+constant also known as [Euler's number](https://oeis.org/A001113). The argument 
+*15* tells the script to evaluate the *15th-degree* Maclaurin polynomial for *e*.
+(That's the Taylor polynomial centered at 0.) Take a look inside the script to
+see how it uses the `shellmath` APIs.
+
+There is another demo script very much like this one but *different*, and the
+sensitive user can *feel* the difference. Try the following, but don't blink 
+or you'll miss it ;)
+```
+$ faster_e_demo.sh 15
+e = 2.7182818284589936
+```
+
+Did you feel the difference? Try the `-t` option with both scripts; this will produce
+timing statistics. Here are my results
+when running from my minGW64 command prompt on Windows 10 with an Intel i3 Core CPU:
+```
+$ for n in {1..5}; do faster_e_demo.sh -t 15 2>&1; done | awk '/^real/ {print $2}'
+0m0.055s
+0m0.051s
+0m0.056s
+0m0.054s
+0m0.054s
+
+$ for n in {1..5}; do slower_e_demo.sh -t 15 2>&1; done | awk '/^real/ {print $2}'
+0m0.498s
+0m0.594s
+0m0.536s
+0m0.511s
+0m0.580s
+```
+
+(When sizing up these timings, do keep in mind that ___we are timing the
+calculation of e from its Maclaurin polynomial. Every invocation of either
+script is exercising the shellmath arithmetic subroutines 31 times.___)
+
+The comment header in `faster_e_demo.sh` explains the optimization and shows
+how to put this faster version to work for you.
+
+## Runtime efficiency competitive with awk and bc
+The file `timingData.txt` captures the results of some timing experiments that compare 
+`shellmath` against the GNU versions of the calculators `awk` and `bc`. The experiments
+exercised each of the arithmetic operations and captured the results in a shell variable.
+The result summary below shows that `shellmath` is competitive with `awk` and runs faster
+than `bc` in these experiments. (One commenter noted that the differences in execution speed
+can be partially explained by the fact that `shellmath` and `awk` use finite precision 
+whereas `bc` uses arbitrary precision. Another factor in these measurements is the need to 
+subshell 'awk' and 'bc' to capture their results, whereas 'shellmath' writes directly to
+the shell's global memory.)
+
+Here are the run times of `shellmath` as a percentage of the `awk` and `bc` equivalents:
+```
+                    versus awk    versus bc
+   Addition:          82.2%         40.6%
+   Subtraction:       95.9%         50.5%
+   Multiplication:   135.9%         73.3%
+   Division:          80.3%         43.2%
+```
+
+Astute observers will note the experiments provide approximations to the sum, difference, 
+product, and quotient of *pi* and *e*. Unfortunately I did not gain insight as to which 
+of these values, if any, are
+[transcendental](https://en.wikipedia.org/wiki/Transcendental_number#Possible_transcendental_numbers).
+
+You can find a deeper discussion of shellmath's runtime efficiency
+[here](https://github.com/clarity20/shellmath/wiki/Shellmath-and-runtime-efficiency).
+
+## Background
+The Bash shell does not have built-in operators for decimal arithmetic, making it
+something of an oddity among well-known, widely-used programming languages. For the most part,
+practitioners in need of powerful computational building blocks have naturally opted
+for *other* languages and tools. Their widespread availability has diverted attention
+from the possibility of *implementing* decimal arithmetic in Bash and it's easy to assume
+that this ***cannot*** be done:
+
++ From the indispensable _Bash FAQ_ (on _Greg's Wiki_): [How can I calculate with floating point numbers?](http://mywiki.wooledge.org/BashFAQ/022)  
+  *"For most operations... an external program must be used."*
++ From Mendel Cooper's wonderful and encyclopedic _Advanced Bash Scripting Guide_:  
+  [Bash does not understand floating point arithmetic. Use bc instead.](https://tldp.org/LDP/abs/html/ops.html#NOFLOATINGPOINT)
++ From a community discussion on Stack Overflow, _How do I use floating point division in bash?_  
+  The user's [preferred answer](https://stackoverflow.com/questions/12722095/how-do-i-use-floating-point-division-in-bash#12722107)
+  is a good example of _prevailing thought_ on this subject.
+
+Meanwhile, 
+
++ Bash maintainer (BDFL?) Chet Ramey sounds a (brighter?) note in [The Bash Reference Guide, Section 6.5](https://tiswww.case.edu/php/chet/bash/bashref.html#Shell-Arithmetic)
+  by emphasizing what the built-in arithmetic operators ***can*** do.
+
+But finally, a glimmer of hope:
+
++ A [diamond-in-the-rough](http://stackoverflow.com/a/24431665/3776858) buried elsewhere
+  on Stack Overflow.  
+  This down-and-dirty milestone computes the decimal quotient of two integer arguments. At a casual
+  glance, it seems to have drawn inspiration from the [Euclidean algorithm](https://mathworld.wolfram.com/EuclideanAlgorithm.html)
+  for computing GCDs, an entirely different approach than `shellmath`'s.
+
+Please try `shellmath` on for size and draw your own conclusions!
+
+## How it works
+`shellmath` splits decimal numbers into their integer and fractional parts,
+performs the appropriate integer operations on the parts, and recombines the results.
+(In the spirit of Bash, numerical overflow is silently ignored.)
+
+Because if we can get carrying, borrowing, place value, and the distributive
+law right, then the sky's the limit! As they say--erm, as they ___said___ in Rome,
+
+        Ad astra per aspera.
+
+## And now...
+You can run your floating-point calculations directly in Bash!
+

+ All arithmetic is done as intmax_t integers with no checking for overflow
+ (though division by 0 is caught and flagged as an error).
+
+ The following operators are handled, grouped into a set of levels in
+ order of decreasing precedence.
+
+	"id++", "id--"		[post-increment and post-decrement]
+	"-", "+"		[(unary operators)]
+	"++id", "--id"		[pre-increment and pre-decrement]
+	"!", "~"
+	"**"			[(exponentiation)]
+	"*", "/", "%"
+	"+", "-"
+	"<<", ">>"
+	"<=", ">=", "<", ">"
+	"==", "!="
+	"&"
+	"^"
+	"|"
+	"&&"
+	"||"
+	"expr ? expr : expr"
+	"=", "*=", "/=", "%=", "+=", "-=", "<<=", ">>=", "&=", "^=", "|="
+	,			[comma]
+
+ (Note that most of these operators have special meaning to bash, and an
+ entire expression should be quoted, e.g. "a=$a+1" or "a=a+1" to ensure
+ that it is passed intact to the evaluator when using `let'.  When using
+ the $[] or $(( )) forms, the text between the `[' and `]' or `((' and `))'
+ is treated as if in double quotes.)
+
+ Sub-expressions within parentheses have a precedence level greater than
+ all of the above levels and are evaluated first.  Within a single prece-
+ dence group, evaluation is left-to-right, except for the arithmetic
+ assignment operator (`='), which is evaluated right-to-left (as in C).
+
+ The expression evaluator returns the value of the expression (assignment
+ statements have as a value what is returned by the RHS).  The `let'
+ builtin, on the other hand, returns 0 if the last expression evaluates to
+ a non-zero, and 1 otherwise.
+
+ Implementation is a recursive-descent parser.

+/* alloca.c -- allocate automatically reclaimed memory
+   (Mostly) portable public-domain implementation -- D A Gwyn
+
+   This implementation of the PWB library alloca function,
+   which is used to allocate space off the run-time stack so
+   that it is automatically reclaimed upon procedure exit,
+   was inspired by discussions with J. Q. Johnson of Cornell.
+   J.Otto Tennant <jot@cray.com> contributed the Cray support.
+
+   There are some preprocessor constants that can
+   be defined when compiling for your specific system, for
+   improved efficiency; however, the defaults should be okay.
+
+   The general concept of this implementation is to keep
+   track of all alloca-allocated blocks, and reclaim any
+   that are found to be deeper in the stack than the current
+   invocation.  This heuristic does not reclaim storage as
+   soon as it becomes invalid, but it will do so eventually.
+
+   As a special case, alloca(0) reclaims storage without
+   allocating any.  It is a good idea to use alloca(0) in
+   your main control loop, etc. to force garbage collection.  */

+ * @(#)nmalloc.c 1 (Caltech) 2/21/82
+ *
+ *	U of M Modified: 20 Jun 1983 ACT: strange hacks for Emacs
+ *
+ *	Nov 1983, Mike@BRL, Added support for 4.1C/4.2 BSD.
+ *
+ * [VERY] old explanation:
+ *
+ * This is a very fast storage allocator.  It allocates blocks of a small 
+ * number of different sizes, and keeps free lists of each size.  Blocks
+ * that don't exactly fit are passed up to the next larger size.  In this 
+ * implementation, the available sizes are (2^n)-4 (or -16) bytes long.
+ * This is designed for use in a program that uses vast quantities of
+ * memory, but bombs when it runs out.  To make it a little better, it
+ * warns the user when he starts to get near the end.
+ *
+ * June 84, ACT: modified rcheck code to check the range given to malloc,
+ * rather than the range determined by the 2-power used.
+ *
+ * Jan 85, RMS: calls malloc_warning to issue warning on nearly full.
+ * No longer Emacs-specific; can serve as all-purpose malloc for GNU.
+ * You should call malloc_init to reinitialize after loading dumped Emacs.
+ * Call malloc_stats to get info on memory stats if MALLOC_STATS turned on.
+ * realloc knows how to return same block given, just changing its size,
+ * if the power of 2 is correct.
+ */
+
+/*
+ * nextf[i] is the pointer to the next free block of size 2^(i+5).  The
+ * smallest allocatable block is 32 bytes. The overhead information will
+ * go in the first 16 bytes of the block, and the returned pointer will point
+ * to the rest.
+ */
+
+/* Define MEMSCRAMBLE to have free() write 0xcf into memory as it's freed, to

+ * If HASH_MIX() is run forward or backward, at least 32 bits in a,b,c

+ * forward, every bit of c will change between 1/3 and 2/3 of the
+ * time.  (Well, 22/100 and 78/100 for some 2-bit deltas.)
+ *
+ * HASH_MIX() takes 36 machine instructions, but only 18 cycles on a
+ * superscalar machine (like a Pentium or a Sparc).  No faster mixer
+ * seems to work, that's the result of my brute-force search.  There

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+
+	* readline.c (parser_if) Allow "$if term=foo" construct.
+
+Wed May 23 16:10:33 1990  Brian Fox  (bfox at gnuwest.fsf.org)
+
+	* readline.c (rl_dispatch) Correctly remember the last command
+	executed.  Fixed typo in username_completion_function ().
+
+Mon Apr  9 19:55:48 1990  Brian Fox  (bfox at gnuwest.fsf.org)
+
+	* readline.c: username_completion_function (); For text passed in
+	with a leading `~', remember that this could be a filename (after
+	it is completed).
+
+Thu Apr  5 13:44:24 1990  Brian Fox  (bfox at gnuwest.fsf.org)
+
+	* readline.c: rl_search_history (): Correctly handle case of an
+	unfound search string, but a graceful exit (as with ESC).
+
+	* readline.c: rl_restart_output ();  The Apollo passes the address
+	of the file descriptor to TIOCSTART, not the descriptor itself.
+
+Tue Mar 20 05:38:55 1990  Brian Fox  (bfox at gnuwest.fsf.org)
+
+	* readline.c: rl_complete (); second call in a row causes possible
+	completions to be listed.
+
+	* readline.c: rl_redisplay (), added prompt_this_line variable
+	which is the first character character following \n in prompt.
+
+Sun Mar 11 04:32:03 1990  Brian Fox  (bfox at gnuwest.fsf.org)
+
+	* Signals are now supposedly handled inside of SYSV compilation.
+
+Wed Jan 17 19:24:09 1990  Brian Fox  (bfox at sbphy.ucsb.edu)
+
+	* history.c: history_expand (); fixed overwriting memory error,
+	added needed argument to call to get_history_event ().
+
+Thu Jan 11 10:54:04 1990  Brian Fox  (bfox at sbphy.ucsb.edu)
+
+	* readline.c: added mark_modified_lines to control the
+	display of an asterisk on modified history lines.  Also
+	added a user variable called mark-modified-lines to the
+	`set' command.
+
+Thu Jan  4 10:38:05 1990  Brian Fox  (bfox at sbphy.ucsb.edu)
+
+	* readline.c: start_insert ().  Only use IC if we don't have an im
+	capability.
+
+Fri Sep  8 09:00:45 1989  Brian Fox  (bfox at aurel)
+
+	* readline.c: rl_prep_terminal ().  Only turn on 8th bit
+	  as meta-bit iff the terminal is not using parity.
+
+Sun Sep  3 08:57:40 1989  Brian Fox  (bfox at aurel)
+
+	* readline.c: start_insert ().  Uses multiple
+	  insertion call in cases where that makes sense.
+
+	  rl_insert ().  Read type-ahead buffer for additional
+	  keys that are bound to rl_insert, and insert them
+	  all at once.  Make insertion of single keys given
+	  with an argument much more efficient.
+
+Tue Aug  8 18:13:57 1989  Brian Fox  (bfox at aurel)
+
+	* readline.c: Changed handling of EOF.  readline () returns
+	 (char *)EOF or consed string.  The EOF character is read from the
+	 tty, or if the tty doesn't have one, defaults to C-d.
+
+	* readline.c: Added support for event driven programs.
+	  rl_event_hook is the address of a function you want called
+	  while Readline is waiting for input.
+
+	* readline.c: Cleanup time.  Functions without type declarations
+	  do not use return with a value.
+
+	* history.c: history_expand () has new variable which is the
+	  characters to ignore immediately following history_expansion_char.
+
+Sun Jul 16 08:14:00 1989  Brian Fox  (bfox at aurel)
+
+	* rl_prep_terminal ()
+	  BSD version turns off C-s, C-q, C-y, C-v.
+
+	* readline.c -- rl_prep_terminal ()
+	  SYSV version hacks readline_echoing_p.
+	  BSD version turns on passing of the 8th bit for the duration
+	  of reading the line.
+
+Tue Jul 11 06:25:01 1989  Brian Fox  (bfox at aurel)
+
+	* readline.c: new variable rl_tilde_expander.
+	  If non-null, this contains the address of a function to call if
+	  the standard meaning for expanding a tilde fails.  The function is
+	  called with the text sans tilde (as in "foo"), and returns a
+	  malloc()'ed string which is the expansion, or a NULL pointer if
+	  there is no expansion. 
+
+	* readline.h - new file chardefs.h
+	  Separates things that only readline.c needs from the standard
+	  header file publishing interesting things about readline.
+
+	* readline.c:
+	  readline_default_bindings () now looks at terminal chararacters
+	  and binds those as well.
+
+Wed Jun 28 20:20:51 1989  Brian Fox  (bfox at aurel)
+
+	* Made readline and history into independent libraries.

+@c hence no sectioning command or @node.

+Copyright @copyright{} 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
+@uref{http://fsf.org/}
+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.

+@item
+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document @dfn{free} in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License.  Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein.  The ``Document'', below,
+refers to any such manual or work.  Any member of the public is a
+licensee, and is addressed as ``you''.  You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject.  (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.  If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant.  The Document may contain zero
+Invariant Sections.  If the Document does not identify any Invariant
+Sections then there are none.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.  A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text.  A copy that is not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+@sc{ascii} without markup, Texinfo input format, La@TeX{} input
+format, @acronym{SGML} or @acronym{XML} using a publicly available
+@acronym{DTD}, and standard-conforming simple @acronym{HTML},
+PostScript or @acronym{PDF} designed for human modification.  Examples
+of transparent image formats include @acronym{PNG}, @acronym{XCF} and
+@acronym{JPG}.  Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, @acronym{SGML} or
+@acronym{XML} for which the @acronym{DTD} and/or processing tools are
+not generally available, and the machine-generated @acronym{HTML},
+PostScript or @acronym{PDF} produced by some word processors for
+output purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+The ``publisher'' means any person or entity that distributes copies
+of the Document to the public.
+
+A section ``Entitled XYZ'' means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language.  (Here XYZ stands for a
+specific section name mentioned below, such as ``Acknowledgements'',
+``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
+of such a section when you modify the Document means that it remains a
+section ``Entitled XYZ'' according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document.  These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License.  You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute.  However, you may accept
+compensation in exchange for copies.  If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover.  Both covers must also clearly and legibly identify
+you as the publisher of these copies.  The front cover must present
+the full title with all words of the title equally prominent and
+visible.  You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it.  In addition, you must do these things in the Modified Version:
+
+@enumerate A
+@item
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document).  You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+@item
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+@item
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+@item
+Preserve all the copyright notices of the Document.
+
+@item
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+@item
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+@item
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+@item
+Include an unaltered copy of this License.
+
+@item
+Preserve the section Entitled ``History'', Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page.  If
+there is no section Entitled ``History'' in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+@item
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on.  These may be placed in the ``History'' section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+@item
+For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+
+@item
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles.  Section numbers
+or the equivalent are not considered part of the section titles.
+
+@item
+Delete any section Entitled ``Endorsements''.  Such a section
+may not be included in the Modified Version.
+
+@item
+Do not retitle any existing section to be Entitled ``Endorsements'' or
+to conflict in title with any Invariant Section.
+
+@item
+Preserve any Warranty Disclaimers.
+@end enumerate
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant.  To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties---for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version.  Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity.  If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+@item
+COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy.  If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled ``History''
+in the various original documents, forming one section Entitled
+``History''; likewise combine any sections Entitled ``Acknowledgements'',
+and any sections Entitled ``Dedications''.  You must delete all
+sections Entitled ``Endorsements.''
+
+@item
+COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+@item
+AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an ``aggregate'' if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+@item
+TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections.  You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers.  In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled ``Acknowledgements'',
+``Dedications'', or ``History'', the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+@item
+TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+
+@item
+FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time.  Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.  See
+@uref{http://www.gnu.org/copyleft/}.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License ``or any later version'' applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation.  If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.  If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.
+
+@item
+RELICENSING
+
+``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works.  A
+public wiki that anybody can edit is an example of such a server.  A
+``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the
+site means any set of copyrightable works thus published on the MMC
+site.
+
+``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0
+license published by Creative Commons Corporation, a not-for-profit
+corporation with a principal place of business in San Francisco,
+California, as well as future copyleft versions of that license
+published by that same organization.
+
+``Incorporate'' means to publish or republish a Document, in whole or
+in part, as part of another Document.
+
+An MMC is ``eligible for relicensing'' if it is licensed under this
+License, and if all works that were first published under this License
+somewhere other than this MMC, and subsequently incorporated in whole
+or in part into the MMC, (1) had no cover texts or invariant sections,
+and (2) were thus incorporated prior to November 1, 2008.
+
+The operator of an MMC Site may republish an MMC contained in the site
+under CC-BY-SA on the same site at any time before August 1, 2009,
+provided the MMC is eligible for relicensing.

+@page
+@heading ADDENDUM: How to use this License for your documents
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+@smallexample
+@group
+  Copyright (C)  @var{year}  @var{your name}.
+  Permission is granted to copy, distribute and/or modify this document
+  under the terms of the GNU Free Documentation License, Version 1.3
+  or any later version published by the Free Software Foundation;
+  with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+  Texts.  A copy of the license is included in the section entitled ``GNU
+  Free Documentation License''.
+@end group
+@end smallexample
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the ``with@dots{}Texts.'' line with this:
+
+@smallexample
+@group
+    with the Invariant Sections being @var{list their titles}, with
+    the Front-Cover Texts being @var{list}, and with the Back-Cover Texts
+    being @var{list}.
+@end group
+@end smallexample
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

+Many programs read input from the user a line at a time.  The @sc{gnu}
+History library is able to keep track of those lines, associate arbitrary
+data with each line, and utilize information from previous lines in
+composing new ones. 
+
+A programmer using the History library has available functions
+for remembering lines on a history list, associating arbitrary data
+with a line, removing lines from the list, searching through the list
+for a line containing an arbitrary text string, and referencing any line
+in the list directly.  In addition, a history @dfn{expansion} function
+is available which provides for a consistent user interface across
+different programs.
+
+The user using programs written with the History library has the
+benefit of a consistent user interface with a set of well-known
+commands for manipulating the text of previous lines and using that text
+in new commands.  The basic history manipulation commands are similar to
+the history substitution provided by @code{csh}.
+
+The programmer can also use the Readline library, which
+includes some history manipulation by default, and has the added
+advantage of command line editing.
+
+Before declaring any functions using any functionality the History
+library provides in other code, an application writer should include
+the file @code{<readline/history.h>} in any file that uses the
+History library's features.  It supplies extern declarations for all
+of the library's public functions and variables, and declares all of
+the public data structures.
+
+@node History Storage
+@section History Storage
+
+The history list is an array of history entries.  A history entry is
+declared as follows:
+
+@example
+typedef void *histdata_t;
+
+typedef struct _hist_entry @{
+  char *line;
+  char *timestamp;
+  histdata_t data;
+@} HIST_ENTRY;
+@end example
+
+The history list itself might therefore be declared as
+
+@example
+HIST_ENTRY **the_history_list;
+@end example
+
+The state of the History library is encapsulated into a single structure:
+
+@example
+/*
+ * A structure used to pass around the current state of the history.
+ */
+typedef struct _hist_state @{
+  HIST_ENTRY **entries; /* Pointer to the entries themselves. */
+  int offset;           /* The location pointer within this array. */
+  int length;           /* Number of elements within this array. */
+  int size;             /* Number of slots allocated to this array. */
+  int flags;
+@} HISTORY_STATE;
+@end example
+
+If the flags member includes @code{HS_STIFLED}, the history has been
+stifled.

+the state of the History library when you want to use the history
+functions in your program.
+
+@deftypefun void using_history (void)
+Begin a session in which the history functions might be used.  This
+initializes the interactive variables.
+@end deftypefun
+
+@deftypefun {HISTORY_STATE *} history_get_history_state (void)

+@node History List Management
+@subsection History List Management
+
+These functions manage individual entries on the history list, or set
+parameters managing the list itself.
+
+@deftypefun void add_history (const char *string)
+Place @var{string} at the end of the history list.  The associated data
+field (if any) is set to @code{NULL}.
+If the maximum number of history entries has been set using

+that maximum, the oldest history entry is removed.
+@end deftypefun
+
+@deftypefun void add_history_time (const char *string)
+Change the time stamp associated with the most recent history entry to
+@var{string}.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} remove_history (int which)
+Remove history entry at offset @var{which} from the history.  The
+removed element is returned so you can free the line, data,

+Stop stifling the history.  This returns the previously-set
+maximum number of history entries (as set by @code{stifle_history()}).
+The value is positive if the history was
+stifled, negative if it wasn't.
+@end deftypefun
+
+@deftypefun int history_is_stifled (void)
+Returns non-zero if the history is stifled, zero if it is not.
+@end deftypefun
+

+
+These functions return information about the entire history list or
+individual list entries.
+
+@deftypefun {HIST_ENTRY **} history_list (void)
+Return a @code{NULL} terminated array of @code{HIST_ENTRY *} which is the
+current input history.  Element 0 of this list is the beginning of time.

+pointer.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} history_get (int offset)
+Return the history entry at position @var{offset}.
+The range of valid
+values of @var{offset} starts at @code{history_base} and ends at
+@var{history_length} - 1 (@pxref{History Variables}).
+If there is no entry there, or if @var{offset} is outside the valid
+range, return a @code{NULL} pointer.
+@end deftypefun

+otherwise, return a @code{BNULL} pointer.
+@end deftypefun
+
+@node Searching the History List
+@subsection Searching the History List
+@cindex History Searching
+
+These functions allow searching of the history list for entries containing
+a specific string.  Searching may be performed both forward and backward
+from the current history position.  The search may be @dfn{anchored},
+meaning that the string must match at the beginning of the history entry.
+@cindex anchored search
+
+@deftypefun int history_search (const char *string, int direction)
+Search the history for @var{string}, starting at the current history offset.
+If @var{direction} is less than 0, then the search is through
+previous entries, otherwise through subsequent entries.
+If @var{string} is found, then
+the current history index is set to that history entry, and the value
+returned is the offset in the line of the entry where
+@var{string} was found.  Otherwise, nothing is changed, and a -1 is
+returned.
+@end deftypefun
+
+@deftypefun int history_search_prefix (const char *string, int direction)
+Search the history for @var{string}, starting at the current history
+offset.  The search is anchored: matching lines must begin with
+@var{string}.  If @var{direction} is less than 0, then the search is
+through previous entries, otherwise through subsequent entries.
+If @var{string} is found, then the
+current history index is set to that entry, and the return value is 0. 
+Otherwise, nothing is changed, and a -1 is returned. 
+@end deftypefun
+
+@deftypefun int history_search_pos (const char *string, int direction, int pos)
+Search for @var{string} in the history list, starting at @var{pos}, an
+absolute index into the list.  If @var{direction} is negative, the search
+proceeds backward from @var{pos}, otherwise forward.  Returns the absolute
+index of the history element where @var{string} was found, or -1 otherwise.
+@end deftypefun
+
+@node Managing the History File
+@subsection Managing the History File
+
+The History library can read the history from and write it to a file.
+This section documents the functions for managing a history file.
+
+@deftypefun int read_history (const char *filename)
+Add the contents of @var{filename} to the history list, a line at a time.
+If @var{filename} is @code{NULL}, then read from @file{~/.history}.
+Returns 0 if successful, or @code{errno} if not.
+@end deftypefun
+
+@deftypefun int read_history_range (const char *filename, int from, int to)
+Read a range of lines from @var{filename}, adding them to the history list.
+Start reading at line @var{from} and end at @var{to}.
+If @var{from} is zero, start at the beginning.  If @var{to} is less than
+@var{from}, then read until the end of the file.  If @var{filename} is
+@code{NULL}, then read from @file{~/.history}.  Returns 0 if successful,
+or @code{errno} if not.
+@end deftypefun
+
+@deftypefun int write_history (const char *filename)
+Write the current history to @var{filename}, overwriting @var{filename}
+if necessary.
+If @var{filename} is @code{NULL}, then write the history list to
+@file{~/.history}.
+Returns 0 on success, or @code{errno} on a read or write error.
+@end deftypefun
+
+@deftypefun int append_history (int nelements, const char *filename)
+Append the last @var{nelements} of the history list to @var{filename}.
+If @var{filename} is @code{NULL}, then append to @file{~/.history}.
+Returns 0 on success, or @code{errno} on a read or write error.
+@end deftypefun
+
+@deftypefun int history_truncate_file (const char *filename, int nlines)
+Truncate the history file @var{filename}, leaving only the last
+@var{nlines} lines.
+If @var{filename} is @code{NULL}, then @file{~/.history} is truncated.
+Returns 0 on success, or @code{errno} on failure.
+@end deftypefun
+
+@node History Expansion
+@subsection History Expansion
+
+These functions implement history expansion.
+
+@deftypefun int history_expand (char *string, char **output)
+Expand @var{string}, placing the result into @var{output}, a pointer
+to a string (@pxref{History Interaction}).  Returns:
+@table @code
+@item 0
+If no expansions took place (or, if the only change in
+the text was the removal of escape characters preceding the history expansion
+character);
+@item 1
+if expansions did take place;
+@item -1
+if there was an error in expansion;
+@item 2
+if the returned line should be displayed, but not executed,
+as with the @code{:p} modifier (@pxref{Modifiers}).
+@end table
+
+If an error occurred in expansion, then @var{output} contains a descriptive
+error message.
+@end deftypefun
+
+@deftypefun {char *} get_history_event (const char *string, int *cindex, int qchar)
+Returns the text of the history event beginning at @var{string} +
+@var{*cindex}.  @var{*cindex} is modified to point to after the event
+specifier.  At function entry, @var{cindex} points to the index into
+@var{string} where the history event specification begins.  @var{qchar}
+is a character that is allowed to end the event specification in addition
+to the ``normal'' terminating characters.
+@end deftypefun
+
+@deftypefun {char **} history_tokenize (const char *string)
+Return an array of tokens parsed out of @var{string}, much as the
+shell might.  The tokens are split on the characters in the
+@var{history_word_delimiters} variable,
+and shell quoting conventions are obeyed as described below.
+@end deftypefun
+
+@deftypefun {char *} history_arg_extract (int first, int last, const char *string)
+Extract a string segment consisting of the @var{first} through @var{last}
+arguments present in @var{string}.  Arguments are split using
+@code{history_tokenize}.
+@end deftypefun
+
+@node History Variables
+@section History Variables
+
+This section describes the externally-visible variables exported by
+the @sc{gnu} History Library.
+
+@deftypevar int history_base
+The logical offset of the first entry in the history list.
+@end deftypevar
+
+@deftypevar int history_length
+The number of entries currently stored in the history list.
+@end deftypevar
+
+@deftypevar int history_max_entries
+The maximum number of history entries.  This must be changed using
+@code{stifle_history()}.
+@end deftypevar
+
+@deftypevar int history_write_timestamps
+If non-zero, timestamps are written to the history file, so they can be
+preserved between sessions.  The default value is 0, meaning that
+timestamps are not saved.
+
+The current timestamp format uses the value of @var{history_comment_char}
+to delimit timestamp entries in the history file.  If that variable does
+not have a value (the default), timestamps will not be written.
+@end deftypevar
+
+@deftypevar char history_expansion_char
+The character that introduces a history event.  The default is @samp{!}.
+Setting this to 0 inhibits history expansion.
+@end deftypevar
+
+@deftypevar char history_subst_char
+The character that invokes word substitution if found at the start of
+a line.  The default is @samp{^}.
+@end deftypevar
+
+@deftypevar char history_comment_char
+During tokenization, if this character is seen as the first character
+of a word, then it and all subsequent characters up to a newline are
+ignored, suppressing history expansion for the remainder of the line.
+This is disabled by default.
+@end deftypevar
+
+@deftypevar {char *} history_word_delimiters
+The characters that separate tokens for @code{history_tokenize()}.
+The default value is @code{" \t\n()<>;&|"}.
+@end deftypevar
+
+@deftypevar {char *} history_search_delimiter_chars
+The list of additional characters which can delimit a history search
+string, in addition to space, TAB, @samp{:} and @samp{?} in the case of
+a substring search.  The default is empty.
+@end deftypevar
+
+@deftypevar {char *} history_no_expand_chars
+The list of characters which inhibit history expansion if found immediately
+following @var{history_expansion_char}.  The default is space, tab, newline,
+carriage return, and @samp{=}.
+@end deftypevar
+
+@deftypevar int history_quotes_inhibit_expansion
+If non-zero, the history expansion code implements shell-like quoting:
+single-quoted words are not scanned for the history expansion
+character or the history comment character, and double-quoted words may
+have history expansion performed, since single quotes are not special
+within double quotes.
+The default value is 0.
+@end deftypevar
+
+@deftypevar int history_quoting_state
+An application may set this variable to indicate that the current line
+being expanded is subject to existing quoting. If set to @samp{'}, the
+history expansion function will assume that the line is single-quoted and
+inhibit expansion until it reads an unquoted closing single quote; if set
+to @samp{"}, history expansion will assume the line is double quoted until
+it reads an unquoted closing double quote. If set to zero, the default,
+the history expansion function will assume the line is not quoted and
+treat quote characters within the line as described above.
+This is only effective if @var{history_quotes_inhibit_expansion} is set.
+@end deftypevar
+
+@deftypevar {rl_linebuf_func_t *} history_inhibit_expansion_function
+This should be set to the address of a function that takes two arguments:
+a @code{char *} (@var{string})
+and an @code{int} index into that string (@var{i}).
+It should return a non-zero value if the history expansion starting at
+@var{string[i]} should not be performed; zero if the expansion should
+be done.
+It is intended for use by applications like Bash that use the history
+expansion character for additional purposes.
+By default, this variable is set to @code{NULL}.

+
+When the @option{-o history} option to the @code{set} builtin
+is enabled (@pxref{The Set Builtin}),
+the shell provides access to the @dfn{command history},
+the list of commands previously typed.
+The value of the @env{HISTSIZE} shell variable is used as the
+number of commands to save in a history list.
+The text of the last @env{$HISTSIZE}
+commands (default 500) is saved.
+The shell stores each command in the history list prior to
+parameter and variable expansion
+but after history expansion is performed, subject to the
+values of the shell variables
+@env{HISTIGNORE} and @env{HISTCONTROL}.
+
+When the shell starts up, the history is initialized from the
+file named by the @env{HISTFILE} variable (default @file{~/.bash_history}).
+The file named by the value of @env{HISTFILE} is truncated, if
+necessary, to contain no more than the number of lines specified by
+the value of the @env{HISTFILESIZE} variable.
+When a shell with history enabled exits, the last
+@env{$HISTSIZE} lines are copied from the history list to the file
+named by @env{$HISTFILE}.
+If the @code{histappend} shell option is set (@pxref{Bash Builtins}),
+the lines are appended to the history file,
+otherwise the history file is overwritten.
+If @env{HISTFILE}
+is unset, or if the history file is unwritable, the history is not saved.
+After saving the history, the history file is truncated
+to contain no more than @env{$HISTFILESIZE} lines.
+If @env{HISTFILESIZE} is unset, or set to null, a non-numeric value, or
+a numeric value less than zero, the history file is not truncated.
+
+If the @env{HISTTIMEFORMAT} is set, the time stamp information
+associated with each history entry is written to the history file,
+marked with the history comment character.
+When the history file is read, lines beginning with the history
+comment character followed immediately by a digit are interpreted
+as timestamps for the following history entry.
+
+The builtin command @code{fc} may be used to list or edit and re-execute
+a portion of the history list.
+The @code{history} builtin may be used to display or modify the history
+list and manipulate the history file.
+When using command-line editing, search commands
+are available in each editing mode that provide access to the
+history list (@pxref{Commands For History}).
+
+The shell allows control over which commands are saved on the history
+list.  The @env{HISTCONTROL} and @env{HISTIGNORE}
+variables may be set to cause the shell to save only a subset of the
+commands entered.
+The @code{cmdhist}
+shell option, if enabled, causes the shell to attempt to save each
+line of a multi-line command in the same history entry, adding
+semicolons where necessary to preserve syntactic correctness.
+The @code{lithist}
+shell option causes the shell to save the command with embedded newlines
+instead of semicolons.
+The @code{shopt} builtin is used to set these options.
+@xref{The Shopt Builtin}, for a description of @code{shopt}.
+
+@node Bash History Builtins
+@section Bash History Builtins
+@cindex history builtins
+
+Bash provides two builtin commands which manipulate the
+history list and history file.
+
+@table @code
+
+@item fc
+@btindex fc
+@example
+@code{fc [-e @var{ename}] [-lnr] [@var{first}] [@var{last}]}
+@code{fc -s [@var{pat}=@var{rep}] [@var{command}]}
+@end example
+
+The first form selects a range of commands from @var{first} to
+@var{last} from the history list and displays or edits and re-executes
+them.
+Both @var{first} and
+@var{last} may be specified as a string (to locate the most recent
+command beginning with that string) or as a number (an index into the
+history list, where a negative number is used as an offset from the
+current command number).
+
+When listing, a @var{first} or @var{last} of 0 is equivalent to -1
+and -0 is equivalent to the current command (usually the @code{fc}
+command);
+otherwise 0 is equivalent to -1 and -0 is invalid.
+
+If @var{last} is not specified, it is set to
+@var{first}.  If @var{first} is not specified, it is set to the previous
+command for editing and @minus{}16 for listing.  If the @option{-l} flag is
+given, the commands are listed on standard output.  The @option{-n} flag
+suppresses the command numbers when listing.  The @option{-r} flag
+reverses the order of the listing.  Otherwise, the editor given by
+@var{ename} is invoked on a file containing those commands.  If
+@var{ename} is not given, the value of the following variable expansion
+is used: @code{$@{FCEDIT:-$@{EDITOR:-vi@}@}}.  This says to use the
+value of the @env{FCEDIT} variable if set, or the value of the
+@env{EDITOR} variable if that is set, or @code{vi} if neither is set.
+When editing is complete, the edited commands are echoed and executed.
+
+In the second form, @var{command} is re-executed after each instance
+of @var{pat} in the selected command is replaced by @var{rep}.
+@var{command} is interpreted the same as @var{first} above.
+
+A useful alias to use with the @code{fc} command is @code{r='fc -s'}, so
+that typing @samp{r cc} runs the last command beginning with @code{cc}
+and typing @samp{r} re-executes the last command (@pxref{Aliases}).
+
+@item history
+@btindex history
+@example
+history [@var{n}]
+history -c
+history -d @var{offset}
+history -d @var{start}-@var{end}
+history [-anrw] [@var{filename}]
+history -ps @var{arg}
+@end example
+
+With no options, display the history list with line numbers.
+Lines prefixed with a @samp{*} have been modified.
+An argument of @var{n} lists only the last @var{n} lines.
+If the shell variable @env{HISTTIMEFORMAT} is set and not null,
+it is used as a format string for @var{strftime} to display
+the time stamp associated with each displayed history entry.
+No intervening blank is printed between the formatted time stamp
+and the history line.
+
+Options, if supplied, have the following meanings:
+
+@table @code
+@item -c
+Clear the history list.  This may be combined
+with the other options to replace the history list completely.
+
+@item -d @var{offset}
+Delete the history entry at position @var{offset}.
+If @var{offset} is positive, it should be specified as it appears when
+the history is displayed.
+If @var{offset} is negative, it is interpreted as relative to one greater
+than the last history position, so negative indices count back from the
+end of the history, and an index of @samp{-1} refers to the current
+@code{history -d} command.
+
+@item -d @var{start}-@var{end}
+Delete the range of history entries between positions @var{start} and
+@var{end}, inclusive.
+Positive and negative values for @var{start} and @var{end}
+are interpreted as described above.
+
+@item -a
+Append the new history lines to the history file.
+These are history lines entered since the beginning of the current
+Bash session, but not already appended to the history file.
+
+@item -n
+Append the history lines not already read from the history file
+to the current history list.  These are lines appended to the history
+file since the beginning of the current Bash session.
+
+@item -r
+Read the history file and append its contents to
+the history list.
+
+@item -w
+Write out the current history list to the history file.
+
+@item -p
+Perform history substitution on the @var{arg}s and display the result
+on the standard output, without storing the results in the history list.
+
+@item -s
+The @var{arg}s are added to the end of
+the history list as a single entry.
+
+@end table
+
+If a @var{filename} argument is supplied
+when any of the @option{-w}, @option{-r}, @option{-a}, or @option{-n} options
+is used, Bash uses @var{filename} as the history file.
+If not, then the value of the @env{HISTFILE} variable is used.
+
+The return value is 0 unless an invalid option is encountered, an
+error occurs while reading or writing the history file, an invalid
+@var{offset} or range is supplied as an argument to @option{-d}, or the
+history expansion supplied as an argument to @option{-p} fails.
+
+@end table
+@end ifset
+
+@node History Interaction
+@section History Expansion
+@cindex history expansion
+
+The History library provides a history expansion feature that is similar
+to the history expansion provided by @code{csh}.  This section
+describes the syntax used to manipulate the history information.
+
+History expansions introduce words from the history list into
+the input stream, making it easy to repeat commands, insert the
+arguments to a previous command into the current input line, or
+fix errors in previous commands quickly.
+
+@ifset BashFeatures
+History expansion is performed immediately after a complete line
+is read, before the shell breaks it into words, and is performed
+on each line individually.  Bash attempts to inform the history
+expansion functions about quoting still in effect from previous lines.
+@end ifset
+
+History expansion takes place in two parts.  The first is to determine
+which line from the history list should be used during substitution.
+The second is to select portions of that line for inclusion into the
+current one.  The line selected from the history is called the
+@dfn{event}, and the portions of that line that are acted upon are
+called @dfn{words}.  Various @dfn{modifiers} are available to manipulate
+the selected words.  The line is broken into words in the same fashion
+that Bash does, so that several words
+surrounded by quotes are considered one word.
+History expansions are introduced by the appearance of the
+history expansion character, which is @samp{!} by default.
+
+History expansion implements shell-like quoting conventions:
+a backslash can be used to remove the special handling for the next character;
+single quotes enclose verbatim sequences of characters, and can be used to
+inhibit history expansion;
+and characters enclosed within double quotes may be subject to history
+expansion, since backslash can escape the history expansion character,
+but single quotes may not, since they are not treated specially within
+double quotes.
+
+@ifset BashFeatures
+When using the shell, only @samp{\} and @samp{'} may be used to escape the
+history expansion character, but the history expansion character is
+also treated as quoted if it immediately precedes the closing double quote
+in a double-quoted string. 
+@end ifset
+
+@ifset BashFeatures
+Several shell options settable with the @code{shopt}
+builtin (@pxref{The Shopt Builtin}) may be used to tailor
+the behavior of history expansion.  If the
+@code{histverify} shell option is enabled, and Readline
+is being used, history substitutions are not immediately passed to
+the shell parser.
+Instead, the expanded line is reloaded into the Readline
+editing buffer for further modification.
+If Readline is being used, and the @code{histreedit}
+shell option is enabled, a failed history expansion will be
+reloaded into the Readline editing buffer for correction.
+The @option{-p} option to the @code{history} builtin command
+may be used to see what a history expansion will do before using it.
+The @option{-s} option to the @code{history} builtin may be used to
+add commands to the end of the history list without actually executing
+them, so that they are available for subsequent recall.
+This is most useful in conjunction with Readline.
+
+The shell allows control of the various characters used by the
+history expansion mechanism with the @code{histchars} variable,
+as explained above (@pxref{Bash Variables}).  The shell uses
+the history comment character to mark history timestamps when
+writing the history file.

+
+@node Event Designators
+@subsection Event Designators
+@cindex event designators
+
+An event designator is a reference to a command line entry in the
+history list.
+Unless the reference is absolute, events are relative to the current
+position in the history list.
+@cindex history events
+
+@table @asis
+
+@item @code{!}
+@ifset BashFeatures
+Start a history substitution, except when followed by a space, tab,
+the end of the line, @samp{=} or @samp{(} (when the
+@code{extglob} shell option is enabled using the @code{shopt} builtin).
+@end ifset
+@ifclear BashFeatures
+Start a history substitution, except when followed by a space, tab,
+the end of the line, or @samp{=}.
+@end ifclear
+
+@item @code{!@var{n}}
+Refer to command line @var{n}.
+
+@item @code{!-@var{n}}
+Refer to the command @var{n} lines back.
+
+@item @code{!!}
+Refer to the previous command.  This is a synonym for @samp{!-1}.
+
+@item @code{!@var{string}}
+Refer to the most recent command
+preceding the current position in the history list
+starting with @var{string}.
+
+@item @code{!?@var{string}[?]}
+Refer to the most recent command
+preceding the current position in the history list
+containing @var{string}.
+The trailing
+@samp{?} may be omitted if the @var{string} is followed immediately by
+a newline.
+If @var{string} is missing, the string from the most recent search is used;
+it is an error if there is no previous search string.
+
+@item @code{^@var{string1}^@var{string2}^}
+Quick Substitution.  Repeat the last command, replacing @var{string1}
+with @var{string2}.  Equivalent to
+@code{!!:s^@var{string1}^@var{string2}^}.
+
+@item @code{!#}
+The entire command line typed so far.
+
+@end table
+
+@node Word Designators
+@subsection Word Designators
+
+Word designators are used to select desired words from the event.
+A @samp{:} separates the event specification from the word designator.  It
+may be omitted if the word designator begins with a @samp{^}, @samp{$},
+@samp{*}, @samp{-}, or @samp{%}.  Words are numbered from the beginning
+of the line, with the first word being denoted by 0 (zero).  Words are
+inserted into the current line separated by single spaces.
+
+@need 0.75
+For example,
+
+@table @code
+@item !!
+designates the preceding command.  When you type this, the preceding
+command is repeated in toto.
+
+@item !!:$
+designates the last argument of the preceding command.  This may be
+shortened to @code{!$}.
+
+@item !fi:2
+designates the second argument of the most recent command starting with
+the letters @code{fi}.
+@end table
+
+@need 0.75
+Here are the word designators:
+ 
+@table @code
+
+@item 0 (zero)
+The @code{0}th word.  For many applications, this is the command word.
+
+@item @var{n}
+The @var{n}th word.
+
+@item ^
+The first argument; that is, word 1.
+
+@item $
+The last argument.
+
+@item %
+The first word matched by the most recent @samp{?@var{string}?} search,
+if the search string begins with a character that is part of a word.
+
+@item @var{x}-@var{y}
+A range of words; @samp{-@var{y}} abbreviates @samp{0-@var{y}}.
+
+@item *
+All of the words, except the @code{0}th.  This is a synonym for @samp{1-$}.
+It is not an error to use @samp{*} if there is just one word in the event;
+the empty string is returned in that case.
+
+@item @var{x}*
+Abbreviates @samp{@var{x}-$}
+
+@item @var{x}-
+Abbreviates @samp{@var{x}-$} like @samp{@var{x}*}, but omits the last word.
+If @samp{x} is missing, it defaults to 0.
+
+@end table
+
+If a word designator is supplied without an event specification, the
+previous command is used as the event.
+
+@node Modifiers
+@subsection Modifiers
+
+After the optional word designator, you can add a sequence of one or more
+of the following modifiers, each preceded by a @samp{:}.
+These modify, or edit, the word or words selected from the history event.
+
+@table @code
+
+@item h
+Remove a trailing pathname component, leaving only the head.
+
+@item t
+Remove all leading pathname components, leaving the tail.
+
+@item r
+Remove a trailing suffix of the form @samp{.@var{suffix}}, leaving
+the basename.
+
+@item e
+Remove all but the trailing suffix.
+
+@item p
+Print the new command but do not execute it.
+
+@ifset BashFeatures
+@item q
+Quote the substituted words, escaping further substitutions.
+
+@item x
+Quote the substituted words as with @samp{q},
+but break into words at spaces, tabs, and newlines.
+The @samp{q} and @samp{x} modifiers are mutually exclusive; the last one
+supplied is used.
+@end ifset
+
+@item s/@var{old}/@var{new}/
+Substitute @var{new} for the first occurrence of @var{old} in the
+event line.
+Any character may be used as the delimiter in place of @samp{/}.
+The delimiter may be quoted in @var{old} and @var{new}
+with a single backslash.  If @samp{&} appears in @var{new},
+it is replaced by @var{old}.  A single backslash will quote
+the @samp{&}.
+If @var{old} is null, it is set to the last @var{old}
+substituted, or, if no previous history substitutions took place,
+the last @var{string}
+in a !?@var{string}@code{[?]}
+search.
+If @var{new} is null, each matching @var{old} is deleted.
+The final delimiter is optional if it is the last
+character on the input line.
+
+@item &
+Repeat the previous substitution.
+
+@item g
+@itemx a
+Cause changes to be applied over the entire event line.  Used in
+conjunction with @samp{s}, as in @code{gs/@var{old}/@var{new}/},
+or with @samp{&}.
+
+@item G
+Apply the following @samp{s} or @samp{&} modifier once to each word
+in the event.

+other programs.  If you are a programmer, and you wish to include the
+features found in @sc{gnu} Readline
+such as completion, line editing, and interactive history manipulation
+in your own programs, this section is for you.

+@end menu
+
+@node Basic Behavior
+@section Basic Behavior
+
+Many programs provide a command line interface, such as @code{mail},
+@code{ftp}, and @code{sh}.  For such programs, the default behaviour of
+Readline is sufficient.  This section describes how to use Readline in
+the simplest way possible, perhaps to replace calls in your code to
+@code{gets()} or @code{fgets()}.
+
+@findex readline
+@cindex readline, function
+
+The function @code{readline()} prints a prompt @var{prompt}
+and then reads and returns a single line of text from the user.
+If @var{prompt} is @code{NULL} or the empty string, no prompt is displayed.
+The line @code{readline} returns is allocated with @code{malloc()};
+the caller should @code{free()} the line when it has finished with it.
+The declaration for @code{readline} in ANSI C is
+
+@example
+@code{char *readline (const char *@var{prompt});}
+@end example
+
+@noindent
+So, one might say
+@example
+@code{char *line = readline ("Enter a line: ");}
+@end example
+@noindent
+in order to read a line of text from the user.
+The line returned has the final newline removed, so only the
+text remains.
+
+If @code{readline} encounters an @code{EOF} while reading the line, and the
+line is empty at that point, then @code{(char *)NULL} is returned.
+Otherwise, the line is ended just as if a newline had been typed.
+
+Readline performs some expansion on the @var{prompt} before it is
+displayed on the screen.  See the description of @code{rl_expand_prompt}
+(@pxref{Redisplay}) for additional details, especially if @var{prompt}
+will contain characters that do not consume physical screen space when
+displayed.
+
+If you want the user to be able to get at the line later, (with
+@key{C-p} for example), you must call @code{add_history()} to save the
+line away in a @dfn{history} list of such lines.
+
+@example
+@code{add_history (line)};
+@end example
+
+@noindent
+For full details on the GNU History Library, see the associated manual.
+
+It is preferable to avoid saving empty lines on the history list, since
+users rarely have a burning need to reuse a blank line.  Here is
+a function which usefully replaces the standard @code{gets()} library
+function, and has the advantage of no static buffer to overflow:
+
+@example
+/* A static variable for holding the line. */
+static char *line_read = (char *)NULL;
+
+/* Read a string, and return a pointer to it.
+   Returns NULL on EOF. */
+char *
+rl_gets ()
+@{
+  /* If the buffer has already been allocated,
+     return the memory to the free pool. */
+  if (line_read)
+    @{
+      free (line_read);
+      line_read = (char *)NULL;
+    @}
+
+  /* Get a line from the user. */
+  line_read = readline ("");
+
+  /* If the line has any text in it,
+     save it on the history. */
+  if (line_read && *line_read)
+    add_history (line_read);
+
+  return (line_read);
+@}
+@end example
+
+This function gives the user the default behaviour of @key{TAB}
+completion: completion on file names.  If you do not want Readline to
+complete on filenames, you can change the binding of the @key{TAB} key
+with @code{rl_bind_key()}.
+
+@example
+@code{int rl_bind_key (int @var{key}, rl_command_func_t *@var{function});}
+@end example
+
+@code{rl_bind_key()} takes two arguments: @var{key} is the character that
+you want to bind, and @var{function} is the address of the function to
+call when @var{key} is pressed.  Binding @key{TAB} to @code{rl_insert()}
+makes @key{TAB} insert itself.
+@code{rl_bind_key()} returns non-zero if @var{key} is not a valid
+ASCII character code (between 0 and 255).
+
+Thus, to disable the default @key{TAB} behavior, the following suffices:
+@example
+@code{rl_bind_key ('\t', rl_insert);}
+@end example
+
+This code should be executed once at the start of your program; you
+might write a function called @code{initialize_readline()} which
+performs this and other desired initializations, such as installing
+custom completers (@pxref{Custom Completers}).
+
+@node Custom Functions
+@section Custom Functions
+
+Readline provides many functions for manipulating the text of
+the line, but it isn't possible to anticipate the needs of all
+programs.  This section describes the various functions and variables
+defined within the Readline library which allow a user program to add
+customized functionality to Readline.
+
+Before declaring any functions that customize Readline's behavior, or
+using any functionality Readline provides in other code, an
+application writer should include the file @code{<readline/readline.h>}
+in any file that uses Readline's features.  Since some of the definitions
+in @code{readline.h} use the @code{stdio} library, the file
+@code{<stdio.h>} should be included before @code{readline.h}.
+
+@code{readline.h} defines a C preprocessor variable that should
+be treated as an integer, @code{RL_READLINE_VERSION}, which may
+be used to conditionally compile application code depending on
+the installed Readline version.  The value is a hexadecimal
+encoding of the major and minor version numbers of the library,
+of the form 0x@var{MMmm}.  @var{MM} is the two-digit major
+version number; @var{mm} is the two-digit minor version number. 
+For Readline 4.2, for example, the value of
+@code{RL_READLINE_VERSION} would be @code{0x0402}.

+
+@node Readline Typedefs
+@subsection Readline Typedefs
+
+For readability, we declare a number of new object types, all pointers
+to functions.
+
+The reason for declaring these new types is to make it easier to write
+code describing pointers to C functions with appropriately prototyped
+arguments and return values.
+
+For instance, say we want to declare a variable @var{func} as a pointer
+to a function which takes two @code{int} arguments and returns an
+@code{int} (this is the type of all of the Readline bindable functions).
+Instead of the classic C declaration
+
+@code{int (*func)();}
+
+@noindent
+or the ANSI-C style declaration
+
+@code{int (*func)(int, int);}
+
+@noindent
+we may write
+
+@code{rl_command_func_t *func;}
+
+The full list of function pointer types available is
+
+@table @code
+@item typedef int rl_command_func_t (int, int);
+
+@item typedef char *rl_compentry_func_t (const char *, int);
+
+@item typedef char **rl_completion_func_t (const char *, int, int);

+@node Function Writing
+@subsection Writing a New Function
+
+In order to write new functions for Readline, you need to know the
+calling conventions for keyboard-invoked functions, and the names of the
+variables that describe the current state of the line read so far.
+
+The calling sequence for a command @code{foo} looks like
+
+@example
+@code{int foo (int count, int key)}
+@end example
+
+@noindent
+where @var{count} is the numeric argument (or 1 if defaulted) and
+@var{key} is the key that invoked this function.
+
+It is completely up to the function as to what should be done with the
+numeric argument.  Some functions use it as a repeat count, some
+as a flag, and others to choose alternate behavior (refreshing the current
+line as opposed to refreshing the screen, for example).  Some choose to
+ignore it.  In general, if a
+function uses the numeric argument as a repeat count, it should be able
+to do something useful with both negative and positive arguments.
+At the very least, it should be aware that it can be passed a
+negative argument.
+
+A command function should return 0 if its action completes successfully,
+and a value greater than zero if some error occurs.
+This is the convention obeyed by all of the builtin Readline bindable
+command functions.
+
+@node Readline Variables
+@section Readline Variables
+
+These variables are available to function writers.
+
+@deftypevar {char *} rl_line_buffer
+This is the line gathered so far.  You are welcome to modify the
+contents of the line, but see @ref{Allowing Undoing}.  The
+function @code{rl_extend_line_buffer} is available to increase
+the memory allocated to @code{rl_line_buffer}.
+@end deftypevar
+
+@deftypevar int rl_point
+The offset of the current cursor position in @code{rl_line_buffer}
+(the @emph{point}).
+@end deftypevar
+
+@deftypevar int rl_end
+The number of characters present in @code{rl_line_buffer}.  When
+@code{rl_point} is at the end of the line, @code{rl_point} and
+@code{rl_end} are equal.
+@end deftypevar
+
+@deftypevar int rl_mark
+The @var{mark} (saved position) in the current line.  If set, the mark
+and point define a @emph{region}.
+@end deftypevar
+
+@deftypevar int rl_done
+Setting this to a non-zero value causes Readline to return the current
+line immediately.
+Readline will set this variable when it has read a key sequence bound
+to @code{accept-line} and is about to return the line to the caller.
+@end deftypevar
+
+@deftypevar int rl_eof_found
+Readline will set this variable when it has read an EOF character (e.g., the
+stty @samp{EOF} character) on an empty line or encountered a read error and
+is about to return a NULL line to the caller.
+@end deftypevar
+
+@deftypevar int rl_num_chars_to_read
+Setting this to a positive value before calling @code{readline()} causes
+Readline to return after accepting that many characters, rather
+than reading up to a character bound to @code{accept-line}.
+@end deftypevar
+
+@deftypevar int rl_pending_input
+Setting this to a value makes it the next keystroke read.  This is a
+way to stuff a single character into the input stream.
+@end deftypevar
+
+@deftypevar int rl_dispatching
+Set to a non-zero value if a function is being called from a key binding;
+zero otherwise.  Application functions can test this to discover whether
+they were called directly or by Readline's dispatching mechanism.
+@end deftypevar
+
+@deftypevar int rl_erase_empty_line
+Setting this to a non-zero value causes Readline to completely erase
+the current line, including any prompt, any time a newline is typed as
+the only character on an otherwise-empty line.  The cursor is moved to
+the beginning of the newly-blank line.
+@end deftypevar
+
+@deftypevar {char *} rl_prompt
+The prompt Readline uses.  This is set from the argument to
+@code{readline()}, and should not be assigned to directly.
+The @code{rl_set_prompt()} function (@pxref{Redisplay}) may
+be used to modify the prompt string after calling @code{readline()}.
+@end deftypevar
+
+@deftypevar {char *} rl_display_prompt
+The string displayed as the prompt.  This is usually identical to
+@var{rl_prompt}, but may be changed temporarily by functions that
+use the prompt string as a message area, such as incremental search.
+@end deftypevar
+
+@deftypevar int rl_already_prompted
+If an application wishes to display the prompt itself, rather than have
+Readline do it the first time @code{readline()} is called, it should set
+this variable to a non-zero value after displaying the prompt.
+The prompt must also be passed as the argument to @code{readline()} so
+the redisplay functions can update the display properly.
+The calling application is responsible for managing the value; Readline
+never sets it.
+@end deftypevar
+
+@deftypevar {const char *} rl_library_version
+The version number of this revision of the library.
+@end deftypevar
+
+@deftypevar int rl_readline_version
+An integer encoding the current version of the library.  The encoding is
+of the form 0x@var{MMmm}, where @var{MM} is the two-digit major version
+number, and @var{mm} is the two-digit minor version number.
+For example, for Readline-4.2, @code{rl_readline_version} would have the
+value 0x0402.
+@end deftypevar
+
+@deftypevar {int} rl_gnu_readline_p
+Always set to 1, denoting that this is @sc{gnu} Readline rather than some
+emulation.
+@end deftypevar
+
+@deftypevar {const char *} rl_terminal_name
+The terminal type, used for initialization.  If not set by the application,
+Readline sets this to the value of the @env{TERM} environment variable
+the first time it is called.
+@end deftypevar
+
+@deftypevar {const char *} rl_readline_name
+This variable is set to a unique name by each application using Readline.
+The value allows conditional parsing of the inputrc file
+(@pxref{Conditional Init Constructs}).
+@end deftypevar
+
+@deftypevar {FILE *} rl_instream
+The stdio stream from which Readline reads input.
+If @code{NULL}, Readline defaults to @var{stdin}.
+@end deftypevar
+
+@deftypevar {FILE *} rl_outstream
+The stdio stream to which Readline performs output.
+If @code{NULL}, Readline defaults to @var{stdout}.
+@end deftypevar
+
+@deftypevar int rl_prefer_env_winsize
+If non-zero, Readline gives values found in the @env{LINES} and
+@env{COLUMNS} environment variables greater precedence than values fetched
+from the kernel when computing the screen dimensions.
+@end deftypevar
+
+@deftypevar {rl_command_func_t *} rl_last_func
+The address of the last command function Readline executed.  May be used to
+test whether or not a function is being executed twice in succession, for
+example.
+@end deftypevar
+
+@deftypevar {rl_hook_func_t *} rl_startup_hook
+If non-zero, this is the address of a function to call just
+before @code{readline} prints the first prompt.
+@end deftypevar
+
+@deftypevar {rl_hook_func_t *} rl_pre_input_hook
+If non-zero, this is the address of a function to call after
+the first prompt has been printed and just before @code{readline}
+starts reading input characters.
+@end deftypevar
+
+@deftypevar {rl_hook_func_t *} rl_event_hook
+If non-zero, this is the address of a function to call periodically
+when Readline is waiting for terminal input.
+By default, this will be called at most ten times a second if there
+is no keyboard input.
+@end deftypevar
+
+@deftypevar {rl_getc_func_t *} rl_getc_function
+If non-zero, Readline will call indirectly through this pointer
+to get a character from the input stream.  By default, it is set to
+@code{rl_getc}, the default Readline character input function
+(@pxref{Character Input}).
+In general, an application that sets @var{rl_getc_function} should consider
+setting @var{rl_input_available_hook} as well.
+@end deftypevar
+
+@deftypevar {rl_hook_func_t *} rl_signal_event_hook
+If non-zero, this is the address of a function to call if a read system
+call is interrupted when Readline is reading terminal input.
+@end deftypevar
+
+@deftypevar {rl_hook_func_t *} rl_timeout_event_hook
+If non-zero, this is the address of a function to call if Readline times
+out while reading input.
+@end deftypevar
+
+@deftypevar {rl_hook_func_t *} rl_input_available_hook
+If non-zero, Readline will use this function's return value when it needs
+to determine whether or not there is available input on the current input
+source.
+The default hook checks @code{rl_instream}; if an application is using a
+different input source, it should set the hook appropriately.
+Readline queries for available input when implementing intra-key-sequence
+timeouts during input and incremental searches.
+This may use an application-specific timeout before returning a value;
+Readline uses the value passed to @code{rl_set_keyboard_input_timeout()}
+or the value of the user-settable @var{keyseq-timeout} variable.
+This is designed for use by applications using Readline's callback interface
+(@pxref{Alternate Interface}), which may not use the traditional
+@code{read(2)} and file descriptor interface, or other applications using
+a different input mechanism.
+If an application uses an input mechanism or hook that can potentially exceed
+the value of @var{keyseq-timeout}, it should increase the timeout or set
+this hook appropriately even when not using the callback interface.
+In general, an application that sets @var{rl_getc_function} should consider
+setting @var{rl_input_available_hook} as well.
+@end deftypevar
+
+@deftypevar {rl_voidfunc_t *} rl_redisplay_function
+If non-zero, Readline will call indirectly through this pointer
+to update the display with the current contents of the editing buffer.
+By default, it is set to @code{rl_redisplay}, the default Readline
+redisplay function (@pxref{Redisplay}).
+@end deftypevar
+
+@deftypevar {rl_vintfunc_t *} rl_prep_term_function
+If non-zero, Readline will call indirectly through this pointer
+to initialize the terminal.  The function takes a single argument, an
+@code{int} flag that says whether or not to use eight-bit characters.
+By default, this is set to @code{rl_prep_terminal}
+(@pxref{Terminal Management}).
+@end deftypevar
+
+@deftypevar {rl_voidfunc_t *} rl_deprep_term_function
+If non-zero, Readline will call indirectly through this pointer
+to reset the terminal.  This function should undo the effects of
+@code{rl_prep_term_function}.
+By default, this is set to @code{rl_deprep_terminal}
+(@pxref{Terminal Management}).
+@end deftypevar
+
+@deftypevar {Keymap} rl_executing_keymap
+This variable is set to the keymap (@pxref{Keymaps}) in which the
+currently executing Readline function was found.
+@end deftypevar 
+
+@deftypevar {Keymap} rl_binding_keymap
+This variable is set to the keymap (@pxref{Keymaps}) in which the
+last key binding occurred.
+@end deftypevar 
+
+@deftypevar {char *} rl_executing_macro
+This variable is set to the text of any currently-executing macro.
+@end deftypevar
+
+@deftypevar int rl_executing_key
+The key that caused the dispatch to the currently-executing Readline function.
+@end deftypevar
+
+@deftypevar {char *} rl_executing_keyseq
+The full key sequence that caused the dispatch to the currently-executing
+Readline function.
+@end deftypevar
+
+@deftypevar int rl_key_sequence_length
+The number of characters in @var{rl_executing_keyseq}.
+@end deftypevar
+
+@deftypevar {int} rl_readline_state
+A variable with bit values that encapsulate the current Readline state.
+A bit is set with the @code{RL_SETSTATE} macro, and unset with the
+@code{RL_UNSETSTATE} macro.  Use the @code{RL_ISSTATE} macro to test
+whether a particular state bit is set.  Current state bits include:

+@node Function Naming
+@subsection Naming a Function
+
+The user can dynamically change the bindings of keys while using
+Readline.  This is done by representing the function with a descriptive
+name.  The user is able to type the descriptive name when referring to
+the function.  Thus, in an init file, one might find
+
+@example
+Meta-Rubout:	backward-kill-word
+@end example
+
+This binds the keystroke @key{Meta-Rubout} to the function
+@emph{descriptively} named @code{backward-kill-word}.  You, as the
+programmer, should bind the functions you write to descriptive names as
+well.  Readline provides a function for doing that:
+
+@deftypefun int rl_add_defun (const char *name, rl_command_func_t *function, int key)
+Add @var{name} to the list of named functions.  Make @var{function} be
+the function that gets called.  If @var{key} is not -1, then bind it to
+@var{function} using @code{rl_bind_key()}.
+@end deftypefun
+
+Using this function alone is sufficient for most applications.
+It is the recommended way to add a few functions to the default
+functions that Readline has built in.
+If you need to do something other than adding a function to Readline,
+you may need to use the underlying functions described below.
+
+@node Keymaps
+@subsection Selecting a Keymap
+
+Key bindings take place on a @dfn{keymap}.  The keymap is the
+association between the keys that the user types and the functions that
+get run.  You can make your own keymaps, copy existing keymaps, and tell
+Readline which keymap to use.
+
+@deftypefun Keymap rl_make_bare_keymap (void)
+Returns a new, empty keymap.  The space for the keymap is allocated with
+@code{malloc()}; the caller should free it by calling
+@code{rl_free_keymap()} when done.
+@end deftypefun
+
+@deftypefun Keymap rl_copy_keymap (Keymap map)
+Return a new keymap which is a copy of @var{map}.
+@end deftypefun
+
+@deftypefun Keymap rl_make_keymap (void)
+Return a new keymap with the printing characters bound to rl_insert,
+the lowercase Meta characters bound to run their equivalents, and
+the Meta digits bound to produce numeric arguments.
+@end deftypefun
+
+@deftypefun void rl_discard_keymap (Keymap keymap)
+Free the storage associated with the data in @var{keymap}.
+The caller should free @var{keymap}.
+@end deftypefun
+
+@deftypefun void rl_free_keymap (Keymap keymap)
+Free all storage associated with @var{keymap}.  This calls
+@code{rl_discard_keymap} to free subordindate keymaps and macros.
+@end deftypefun
+
+@deftypefun int rl_empty_keymap (Keymap keymap)
+Return non-zero if there are no keys bound to functions in @var{keymap};
+zero if there are any keys bound.
+@end deftypefun
+
+Readline has several internal keymaps.  These functions allow you to
+change which keymap is active.
+
+@deftypefun Keymap rl_get_keymap (void)
+Returns the currently active keymap.
+@end deftypefun
+
+@deftypefun void rl_set_keymap (Keymap keymap)
+Makes @var{keymap} the currently active keymap.
+@end deftypefun
+
+@deftypefun Keymap rl_get_keymap_by_name (const char *name)
+Return the keymap matching @var{name}.  @var{name} is one which would
+be supplied in a @code{set keymap} inputrc line (@pxref{Readline Init File}).
+@end deftypefun
+
+@deftypefun {char *} rl_get_keymap_name (Keymap keymap)
+Return the name matching @var{keymap}.  @var{name} is one which would
+be supplied in a @code{set keymap} inputrc line (@pxref{Readline Init File}).
+@end deftypefun
+
+@deftypefun int rl_set_keymap_name (const char *name, Keymap keymap)
+Set the name of @var{keymap}.  This name will then be "registered" and
+available for use in a @code{set keymap} inputrc directive
+@pxref{Readline Init File}).
+The @var{name} may not be one of Readline's builtin keymap names;
+you may not add a different name for one of Readline's builtin keymaps.
+You may replace the name associated with a given keymap by calling this
+function more than once with the same @var{keymap} argument.
+You may associate a registered @var{name} with a new keymap by calling this
+function more than once  with the same @var{name} argument.
+There is no way to remove a named keymap once the name has been
+registered.
+Readline will make a copy of @var{name}.
+The return value is greater than zero unless @var{name} is one of
+Readline's builtin keymap names or @var{keymap} is one of Readline's
+builtin keymaps.
+@end deftypefun
+
+@node Binding Keys
+@subsection Binding Keys
+
+Key sequences are associate with functions through the keymap.
+Readline has several internal keymaps: @code{emacs_standard_keymap},
+@code{emacs_meta_keymap}, @code{emacs_ctlx_keymap},
+@code{vi_movement_keymap}, and @code{vi_insertion_keymap}.
+@code{emacs_standard_keymap} is the default, and the examples in
+this manual assume that.
+
+Since @code{readline()} installs a set of default key bindings the first
+time it is called, there is always the danger that a custom binding
+installed before the first call to @code{readline()} will be overridden.
+An alternate mechanism is to install custom key bindings in an
+initialization function assigned to the @code{rl_startup_hook} variable
+(@pxref{Readline Variables}).
+
+These functions manage key bindings.
+
+@deftypefun int rl_bind_key (int key, rl_command_func_t *function)
+Binds @var{key} to @var{function} in the currently active keymap.
+Returns non-zero in the case of an invalid @var{key}.
+@end deftypefun
+
+@deftypefun int rl_bind_key_in_map (int key, rl_command_func_t *function, Keymap map)
+Bind @var{key} to @var{function} in @var{map}.
+Returns non-zero in the case of an invalid @var{key}.
+@end deftypefun
+
+@deftypefun int rl_bind_key_if_unbound (int key, rl_command_func_t *function)
+Binds @var{key} to @var{function} if it is not already bound in the
+currently active keymap.
+Returns non-zero in the case of an invalid @var{key} or if @var{key} is
+already bound.
+@end deftypefun
+
+@deftypefun int rl_bind_key_if_unbound_in_map (int key, rl_command_func_t *function, Keymap map)
+Binds @var{key} to @var{function} if it is not already bound in @var{map}.
+Returns non-zero in the case of an invalid @var{key} or if @var{key} is
+already bound.
+@end deftypefun
+
+@deftypefun int rl_unbind_key (int key)
+Bind @var{key} to the null function in the currently active keymap.
+Returns non-zero in case of error.
+@end deftypefun
+
+@deftypefun int rl_unbind_key_in_map (int key, Keymap map)
+Bind @var{key} to the null function in @var{map}.

+@node Allowing Undoing
+@subsection Allowing Undoing
+
+Supporting the undo command is a painless thing, and makes your
+functions much more useful.  It is certainly easy to try
+something if you know you can undo it.
+
+If your function simply inserts text once, or deletes text once, and
+uses @code{rl_insert_text()} or @code{rl_delete_text()} to do it, then
+undoing is already done for you automatically.
+
+If you do multiple insertions or multiple deletions, or any combination
+of these operations, you should group them together into one operation.
+This is done with @code{rl_begin_undo_group()} and
+@code{rl_end_undo_group()}.
+
+The types of events that can be undone are:
+
+@smallexample
+enum undo_code @{ UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END @}; 
+@end smallexample
+
+Notice that @code{UNDO_DELETE} means to insert some text, and
+@code{UNDO_INSERT} means to delete some text.  That is, the undo code
+tells what to undo, not how to undo it.  @code{UNDO_BEGIN} and
+@code{UNDO_END} are tags added by @code{rl_begin_undo_group()} and
+@code{rl_end_undo_group()}.
+
+@deftypefun int rl_begin_undo_group (void)
+Begins saving undo information in a group construct.  The undo
+information usually comes from calls to @code{rl_insert_text()} and
+@code{rl_delete_text()}, but could be the result of calls to
+@code{rl_add_undo()}.
+@end deftypefun
+
+@deftypefun int rl_end_undo_group (void)
+Closes the current undo group started with @code{rl_begin_undo_group
+()}.  There should be one call to @code{rl_end_undo_group()}
+for each call to @code{rl_begin_undo_group()}.
+@end deftypefun
+
+@deftypefun void rl_add_undo (enum undo_code what, int start, int end, char *text)
+Remember how to undo an event (according to @var{what}).  The affected
+text runs from @var{start} to @var{end}, and encompasses @var{text}.
+@end deftypefun
+
+@deftypefun void rl_free_undo_list (void)
+Free the existing undo list.
+@end deftypefun
+
+@deftypefun int rl_do_undo (void)
+Undo the first thing on the undo list.  Returns @code{0} if there was
+nothing to undo, non-zero if something was undone.
+@end deftypefun
+
+Finally, if you neither insert nor delete text, but directly modify the
+existing text (e.g., change its case), call @code{rl_modifying()}
+once, just before you modify the text.  You must supply the indices of
+the text range that you are going to modify.
+
+@deftypefun int rl_modifying (int start, int end)
+Tell Readline to save the text between @var{start} and @var{end} as a

+that text.

+as the History library's @code{clear_history()} function.
+This differs from @code{clear_history} because it frees private data
+Readline saves in the history list.
+@end deftypefun
+
+@deftypefun {void} rl_activate_mark (void)
+Enable an @emph{active} mark.
+When this is enabled, the text between point and mark (the @var{region}) is

+This is called by various Readline functions that set the mark and insert

+@node Alternate Interface
+@subsection Alternate Interface
+
+An alternate interface is available to plain @code{readline()}.  Some
+applications need to interleave keyboard I/O with file, device, or
+window system I/O, typically by using a main loop to @code{select()}
+on various file descriptors.  To accommodate this need, Readline can
+also be invoked as a `callback' function from an event loop.  There
+are functions available to make this easy.
+
+@deftypefun void rl_callback_handler_install (const char *prompt, rl_vcpfunc_t *lhandler)
+Set up the terminal for Readline I/O and display the initial
+expanded value of @var{prompt}.  Save the value of @var{lhandler} to
+use as a handler function to call when a complete line of input has been
+entered.
+The handler function receives the text of the line as an argument.
+As with @code{readline()}, the handler function should @code{free} the
+line when it it finished with it.
+@end deftypefun
+
+@deftypefun void rl_callback_read_char (void)
+Whenever an application determines that keyboard input is available, it
+should call @code{rl_callback_read_char()}, which will read the next
+character from the current input source.
+If that character completes the line, @code{rl_callback_read_char} will
+invoke the @var{lhandler} function installed by
+@code{rl_callback_handler_install} to process the line.
+Before calling the @var{lhandler} function, the terminal settings are
+reset to the values they had before calling
+@code{rl_callback_handler_install}.
+If the @var{lhandler} function returns,
+and the line handler remains installed,
+the terminal settings are modified for Readline's use again.
+@code{EOF} is indicated by calling @var{lhandler} with a
+@code{NULL} line.
+@end deftypefun
+
+@deftypefun void rl_callback_sigcleanup (void)
+Clean up any internal state the callback interface uses to maintain state
+between calls to rl_callback_read_char (e.g., the state of any active
+incremental searches).  This is intended to be used by applications that
+wish to perform their own signal handling; Readline's internal signal handler
+calls this when appropriate.
+@end deftypefun
+
+@deftypefun void rl_callback_handler_remove (void)
+Restore the terminal to its initial state and remove the line handler.
+You may call this function from within a callback as well as independently.
+If the @var{lhandler} installed by @code{rl_callback_handler_install}
+does not exit the program, either this function or the function referred
+to by the value of @code{rl_deprep_term_function} should be called before
+the program exits to reset the terminal settings.

+@node Readline Signal Handling
+@section Readline Signal Handling
+
+Signals are asynchronous events sent to a process by the Unix kernel,
+sometimes on behalf of another process.  They are intended to indicate
+exceptional events, like a user pressing the terminal's interrupt key,
+or a network connection being broken.  There is a class of signals that can
+be sent to the process currently reading input from the keyboard.  Since
+Readline changes the terminal attributes when it is called, it needs to
+perform special processing when such a signal is received in order to
+restore the terminal to a sane state, or provide application writers with
+functions to do so manually. 
+
+Readline contains an internal signal handler that is installed for a
+number of signals (@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM},
+@code{SIGHUP}, 
+@code{SIGALRM}, @code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}).
+When one of these signals is received, the signal handler
+will reset the terminal attributes to those that were in effect before
+@code{readline()} was called, reset the signal handling to what it was
+before @code{readline()} was called, and resend the signal to the calling
+application.
+If and when the calling application's signal handler returns, Readline
+will reinitialize the terminal and continue to accept input.
+When a @code{SIGINT} is received, the Readline signal handler performs
+some additional work, which will cause any partially-entered line to be
+aborted (see the description of @code{rl_free_line_state()} below).
+
+There is an additional Readline signal handler, for @code{SIGWINCH}, which
+the kernel sends to a process whenever the terminal's size changes (for
+example, if a user resizes an @code{xterm}).  The Readline @code{SIGWINCH}
+handler updates Readline's internal screen size information, and then calls
+any @code{SIGWINCH} signal handler the calling application has installed. 
+Readline calls the application's @code{SIGWINCH} signal handler without
+resetting the terminal to its original state.  If the application's signal
+handler does more than update its idea of the terminal size and return (for
+example, a @code{longjmp} back to a main processing loop), it @emph{must}
+call @code{rl_cleanup_after_signal()} (described below), to restore the
+terminal state.
+
+When an application is using the callback interface
+(@pxref{Alternate Interface}), Readline installs signal handlers only for
+the duration of the call to @code{rl_callback_read_char}.  Applications
+using the callback interface should be prepared to clean up Readline's
+state if they wish to handle the signal before the line handler completes
+and restores the terminal state.
+
+If an application using the callback interface wishes to have Readline
+install its signal handlers at the time the application calls
+@code{rl_callback_handler_install} and remove them only when a complete
+line of input has been read, it should set the
+@code{rl_persistent_signal_handlers} variable to a non-zero value.
+This allows an application to defer all of the handling of the signals
+Readline catches to Readline.
+Applications should use this variable with care; it can result in Readline
+catching signals and not acting on them (or allowing the application to react
+to them) until the application calls @code{rl_callback_read_char}.  This
+can result in an application becoming less responsive to keyboard signals
+like SIGINT.
+If an application does not want or need to perform any signal handling, or
+does not need to do any processing between calls to @code{rl_callback_read_char},
+setting this variable may be desirable.
+
+Readline provides two variables that allow application writers to
+control whether or not it will catch certain signals and act on them
+when they are received.  It is important that applications change the
+values of these variables only when calling @code{readline()}, not in
+a signal handler, so Readline's internal signal state is not corrupted.
+
+@deftypevar int rl_catch_signals
+If this variable is non-zero, Readline will install signal handlers for
+@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM}, @code{SIGHUP}, @code{SIGALRM},
+@code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}.
+
+The default value of @code{rl_catch_signals} is 1.
+@end deftypevar
+
+@deftypevar int rl_catch_sigwinch
+If this variable is set to a non-zero value,
+Readline will install a signal handler for @code{SIGWINCH}.
+
+The default value of @code{rl_catch_sigwinch} is 1.
+@end deftypevar
+
+@deftypevar int rl_persistent_signal_handlers
+If an application using the callback interface wishes Readline's signal
+handlers to be installed and active during the set of calls to
+@code{rl_callback_read_char} that constitutes an entire single line,
+it should set this variable to a non-zero value.
+
+The default value of @code{rl_persistent_signal_handlers} is 0.
+@end deftypevar
+
+@deftypevar int rl_change_environment
+If this variable is set to a non-zero value,
+and Readline is handling @code{SIGWINCH}, Readline will modify the
+@var{LINES} and @var{COLUMNS} environment variables upon receipt of a
+@code{SIGWINCH}
+
+The default value of @code{rl_change_environment} is 1.
+@end deftypevar
+
+If an application does not wish to have Readline catch any signals, or
+to handle signals other than those Readline catches (@code{SIGHUP},
+for example), 
+Readline provides convenience functions to do the necessary terminal
+and internal state cleanup upon receipt of a signal.
+
+@deftypefun int rl_pending_signal (void)
+Return the signal number of the most recent signal Readline received but
+has not yet handled, or 0 if there is no pending signal.
+@end deftypefun

+This function will reset the state of the terminal to what it was before
+@code{readline()} was called, and remove the Readline signal handlers for
+all signals, depending on the values of @code{rl_catch_signals} and
+@code{rl_catch_sigwinch}.
+@end deftypefun
+
+@deftypefun void rl_free_line_state (void)
+This will free any partial state associated with the current input line
+(undo information, any partial history entry, any partially-entered
+keyboard macro, and any partially-entered numeric argument).  This
+should be called before @code{rl_cleanup_after_signal()}.  The
+Readline signal handler for @code{SIGINT} calls this to abort the
+current input line.
+@end deftypefun
+
+@deftypefun void rl_reset_after_signal (void)
+This will reinitialize the terminal and reinstall any Readline signal
+handlers, depending on the values of @code{rl_catch_signals} and
+@code{rl_catch_sigwinch}.
+@end deftypefun
+
+If an application wants to force Readline to handle any signals that
+have arrived while it has been executing, @code{rl_check_signals()}
+will call Readline's internal signal handler if there are any pending
+signals.  This is primarily intended for those applications that use
+a custom @code{rl_getc_function} (@pxref{Readline Variables}) and wish
+to handle signals received while waiting for input.
+
+@deftypefun void rl_check_signals (void)
+If there are any pending signals, call Readline's internal signal handling
+functions to process them. @code{rl_pending_signal()} can be used independently
+to determine whether or not there are any pending signals.
+@end deftypefun
+
+If an application does not wish Readline to catch @code{SIGWINCH}, it may
+call @code{rl_resize_terminal()} or @code{rl_set_screen_size()} to force
+Readline to update its idea of the terminal size when it receives
+a @code{SIGWINCH}.
+
+@deftypefun void rl_echo_signal_char (int sig)
+If an application wishes to install its own signal handlers, but still
+have Readline display characters that generate signals, calling this
+function with @var{sig} set to @code{SIGINT}, @code{SIGQUIT}, or
+@code{SIGTSTP} will display the character generating that signal.

+Update Readline's internal screen size by reading values from the kernel.

+Set Readline's idea of the terminal size to @var{rows} rows and

+or equal to 0, Readline's idea of that terminal dimension is unchanged.
+This is intended to tell Readline the physical dimensions of the terminal,
+and is used internally to calculate the maximum number of characters that
+may appear on a single line and on the screen.
+@end deftypefun
+
+If an application does not want to install a @code{SIGWINCH} handler, but

+@node How Completing Works
+@subsection How Completing Works
+
+In order to complete some text, the full list of possible completions
+must be available.  That is, it is not possible to accurately
+expand a partial word without knowing all of the possible words
+which make sense in that context.  The Readline library provides
+the user interface to completion, and two of the most common
+completion functions:  filename and username.  For completing other types
+of text, you must write your own completion function.  This section
+describes exactly what such functions must do, and provides an example.
+
+There are three major functions used to perform completion:
+
+@enumerate
+@item
+The user-interface function @code{rl_complete()}.  This function is
+called with the same arguments as other bindable Readline functions:
+@var{count} and @var{invoking_key}.
+It isolates the word to be completed and calls
+@code{rl_completion_matches()} to generate a list of possible completions.
+It then either lists the possible completions, inserts the possible
+completions, or actually performs the
+completion, depending on which behavior is desired.
+
+@item
+The internal function @code{rl_completion_matches()} uses an
+application-supplied @dfn{generator} function to generate the list of
+possible matches, and then returns the array of these matches.
+The caller should place the address of its generator function in
+@code{rl_completion_entry_function}.
+
+@item
+The generator function is called repeatedly from
+@code{rl_completion_matches()}, returning a string each time.  The
+arguments to the generator function are @var{text} and @var{state}.
+@var{text} is the partial word to be completed.  @var{state} is zero the
+first time the function is called, allowing the generator to perform
+any necessary initialization, and a positive non-zero integer for
+each subsequent call.  The generator function returns
+@code{(char *)NULL} to inform @code{rl_completion_matches()} that there are
+no more possibilities left.  Usually the generator function computes the
+list of possible completions when @var{state} is zero, and returns them
+one at a time on subsequent calls.  Each string the generator function
+returns as a match must be allocated with @code{malloc()}; Readline
+frees the strings when it has finished with them.
+Such a generator function is referred to as an
+@dfn{application-specific completion function}.
+
+@end enumerate
+
+@deftypefun int rl_complete (int ignore, int invoking_key)
+Complete the word at or before point.  You have supplied the function
+that does the initial simple matching selection algorithm (see
+@code{rl_completion_matches()}).  The default is to do filename completion.
+@end deftypefun
+
+@deftypevar {rl_compentry_func_t *} rl_completion_entry_function
+This is a pointer to the generator function for
+@code{rl_completion_matches()}.
+If the value of @code{rl_completion_entry_function} is
+@code{NULL} then the default filename generator
+function, @code{rl_filename_completion_function()}, is used.
+An @dfn{application-specific completion function} is a function whose
+address is assigned to @code{rl_completion_entry_function} and whose
+return values are used to  generate possible completions.

+@subsection Completion Functions
+
+Here is the complete list of callable completion functions present in
+Readline.
+
+@deftypefun int rl_complete_internal (int what_to_do)
+Complete the word at or before point.  @var{what_to_do} says what to do
+with the completion.  A value of @samp{?} means list the possible
+completions.  @samp{TAB} means do standard completion.  @samp{*} means
+insert all of the possible completions.  @samp{!} means to display
+all of the possible completions, if there is more than one, as well as
+performing partial completion.  @samp{@@} is similar to @samp{!}, but
+possible completions are not listed if the possible completions share
+a common prefix.
+@end deftypefun
+
+@deftypefun int rl_complete (int ignore, int invoking_key)
+Complete the word at or before point.  You have supplied the function
+that does the initial simple matching selection algorithm (see
+@code{rl_completion_matches()} and @code{rl_completion_entry_function}).
+The default is to do filename
+completion.  This calls @code{rl_complete_internal()} with an
+argument depending on @var{invoking_key}.
+@end deftypefun
+
+@deftypefun int rl_possible_completions (int count, int invoking_key)
+List the possible completions.  See description of @code{rl_complete
+()}.  This calls @code{rl_complete_internal()} with an argument of
+@samp{?}.
+@end deftypefun
+
+@deftypefun int rl_insert_completions (int count, int invoking_key)
+Insert the list of possible completions into the line, deleting the
+partially-completed word.  See description of @code{rl_complete()}.
+This calls @code{rl_complete_internal()} with an argument of @samp{*}.
+@end deftypefun
+
+@deftypefun int rl_completion_mode (rl_command_func_t *cfunc)
+Returns the appropriate value to pass to @code{rl_complete_internal()}
+depending on whether @var{cfunc} was called twice in succession and
+the values of the @code{show-all-if-ambiguous} and
+@code{show-all-if-unmodified} variables.
+Application-specific completion functions may use this function to present
+the same interface as @code{rl_complete()}.
+@end deftypefun
+
+@deftypefun {char **} rl_completion_matches (const char *text, rl_compentry_func_t *entry_func)
+Returns an array of strings which is a list of completions for
+@var{text}.  If there are no completions, returns @code{NULL}.
+The first entry in the returned array is the substitution for @var{text}.
+The remaining entries are the possible completions.  The array is
+terminated with a @code{NULL} pointer.
+
+@var{entry_func} is a function of two args, and returns a
+@code{char *}.  The first argument is @var{text}.  The second is a
+state argument; it is zero on the first call, and non-zero on subsequent
+calls.  @var{entry_func} returns a @code{NULL}  pointer to the caller
+when there are no more matches.
+@end deftypefun
+
+@deftypefun {char *} rl_filename_completion_function (const char *text, int state)
+A generator function for filename completion in the general case.
+@var{text} is a partial filename.
+The Bash source is a useful reference for writing application-specific
+completion functions (the Bash completion functions call this and other
+Readline functions).

+username preceded by a random character (usually @samp{~}).  As with all
+completion generators, @var{state} is zero on the first call and non-zero
+for subsequent calls.
+@end deftypefun
+
+@node Completion Variables
+@subsection Completion Variables
+
+@deftypevar {rl_compentry_func_t *} rl_completion_entry_function
+A pointer to the generator function for @code{rl_completion_matches()}.
+@code{NULL} means to use @code{rl_filename_completion_function()},
+the default filename completer.
+@end deftypevar
+
+@deftypevar {rl_completion_func_t *} rl_attempted_completion_function
+A pointer to an alternative function to create matches.
+The function is called with @var{text}, @var{start}, and @var{end}.
+@var{start} and @var{end} are indices in @code{rl_line_buffer} defining
+the boundaries of @var{text}, which is a character string.
+If this function exists and returns @code{NULL}, or if this variable is
+set to @code{NULL}, then @code{rl_complete()} will call the value of
+@code{rl_completion_entry_function} to generate matches, otherwise the
+array of strings returned will be used.
+If this function sets the @code{rl_attempted_completion_over}
+variable to a non-zero value, Readline will not perform its default
+completion even if this function returns no matches.
+@end deftypevar
+
+@deftypevar {rl_quote_func_t *} rl_filename_quoting_function
+A pointer to a function that will quote a filename in an
+application-specific fashion.  This is called if filename completion is being
+attempted and one of the characters in @code{rl_filename_quote_characters}
+appears in a completed filename.  The function is called with
+@var{text}, @var{match_type}, and @var{quote_pointer}.  The @var{text}
+is the filename to be quoted.  The @var{match_type} is either
+@code{SINGLE_MATCH}, if there is only one completion match, or
+@code{MULT_MATCH}.  Some functions use this to decide whether or not to
+insert a closing quote character.  The @var{quote_pointer} is a pointer
+to any opening quote character the user typed.  Some functions choose
+to reset this character.
+@end deftypevar
+
+@deftypevar {rl_dequote_func_t *} rl_filename_dequoting_function
+A pointer to a function that will remove application-specific quoting
+characters from a filename before completion is attempted, so those
+characters do not interfere with matching the text against names in
+the filesystem.  It is called with @var{text}, the text of the word
+to be dequoted, and @var{quote_char}, which is the quoting character 
+that delimits the filename (usually @samp{'} or @samp{"}).  If
+@var{quote_char} is zero, the filename was not in an embedded string.
+@end deftypevar
+
+@deftypevar {rl_linebuf_func_t *} rl_char_is_quoted_p
+A pointer to a function to call that determines whether or not a specific
+character in the line buffer is quoted, according to whatever quoting
+mechanism the program calling Readline uses.  The function is called with
+two arguments: @var{text}, the text of the line, and @var{index}, the
+index of the character in the line.  It is used to decide whether a
+character found in @code{rl_completer_word_break_characters} should be
+used to break words for the completer.
+@end deftypevar
+
+@deftypevar {rl_compignore_func_t *} rl_ignore_some_completions_function
+This function, if defined, is called by the completer when real filename
+completion is done, after all the matching names have been generated.
+It is passed a @code{NULL} terminated array of matches.
+The first element (@code{matches[0]}) is the
+maximal substring common to all matches. This function can
+re-arrange the list of matches as required, but each element deleted
+from the array must be freed.
+@end deftypevar
+
+@deftypevar {rl_icppfunc_t *} rl_directory_completion_hook
+This function, if defined, is allowed to modify the directory portion
+of filenames Readline completes.
+It could be used to expand symbolic links or shell variables in pathnames.
+It is called with the address of a string (the current directory name) as an
+argument, and may modify that string.
+If the string is replaced with a new string, the old value should be freed.
+Any modified directory name should have a trailing slash.
+The modified value will be used as part of the completion, replacing
+the directory portion of the pathname the user typed.
+At the least, even if no other expansion is performed, this function should
+remove any quote characters from the directory name, because its result will
+be passed directly to @code{opendir()}.
+
+The directory completion hook returns an integer that should be non-zero if
+the function modifies its directory argument.
+The function should not modify the directory argument if it returns 0.
+@end deftypevar
+
+@deftypevar {rl_icppfunc_t *} rl_directory_rewrite_hook;
+If non-zero, this is the address of a function to call when completing
+a directory name.  This function takes the address of the directory name
+to be modified as an argument.  Unlike @code{rl_directory_completion_hook},
+it only modifies the directory name used in @code{opendir}, not what is
+displayed when the possible completions are printed or inserted.  It is
+called before rl_directory_completion_hook.
+At the least, even if no other expansion is performed, this function should
+remove any quote characters from the directory name, because its result will
+be passed directly to @code{opendir()}.
+
+The directory rewrite hook returns an integer that should be non-zero if
+the function modifies its directory argument.
+The function should not modify the directory argument if it returns 0.
+@end deftypevar
+
+@deftypevar {rl_icppfunc_t *} rl_filename_stat_hook
+If non-zero, this is the address of a function for the completer to
+call before deciding which character to append to a completed name.
+This function modifies its filename name argument, and the modified value
+is passed to @code{stat()} to determine the file's type and characteristics.
+This function does not need to remove quote characters from the filename.
+
+The stat hook returns an integer that should be non-zero if
+the function modifies its directory argument.
+The function should not modify the directory argument if it returns 0.
+@end deftypevar
+
+@deftypevar {rl_dequote_func_t *} rl_filename_rewrite_hook
+If non-zero, this is the address of a function called when reading
+directory entries from the filesystem for completion and comparing
+them to the partial word to be completed.  The function should
+perform any necessary application or system-specific conversion on
+the filename, such as converting between character sets or converting
+from a filesystem format to a character input format.
+The function takes two arguments: @var{fname}, the filename to be converted,
+and @var{fnlen}, its length in bytes.
+It must either return its first argument (if no conversion takes place)
+or the converted filename in newly-allocated memory.  The converted
+form is used to compare against the word to be completed, and, if it
+matches, is added to the list of matches.  Readline will free the
+allocated string.
+@end deftypevar
+
+@deftypevar {rl_compdisp_func_t *} rl_completion_display_matches_hook
+If non-zero, then this is the address of a function to call when
+completing a word would normally display the list of possible matches.
+This function is called in lieu of Readline displaying the list.
+It takes three arguments:
+(@code{char **}@var{matches}, @code{int} @var{num_matches}, @code{int} @var{max_length})
+where @var{matches} is the array of matching strings,
+@var{num_matches} is the number of strings in that array, and
+@var{max_length} is the length of the longest string in that array.
+Readline provides a convenience function, @code{rl_display_match_list},
+that takes care of doing the display to Readline's output stream.
+You may call that function from this hook.
+@end deftypevar
+
+@deftypevar {const char *} rl_basic_word_break_characters
+The basic list of characters that signal a break between words for the
+completer routine.  The default value of this variable is the characters
+which break words for completion in Bash:
+@code{" \t\n\"\\'`@@$><=;|&@{("}.
+@end deftypevar
+
+@deftypevar {const char *} rl_basic_quote_characters
+A list of quote characters which can cause a word break.
+@end deftypevar
+
+@deftypevar {const char *} rl_completer_word_break_characters
+The list of characters that signal a break between words for
+@code{rl_complete_internal()}.  The default list is the value of
+@code{rl_basic_word_break_characters}.
+@end deftypevar
+
+@deftypevar {rl_cpvfunc_t *} rl_completion_word_break_hook
+If non-zero, this is the address of a function to call when Readline is
+deciding where to separate words for word completion.  It should return
+a character string like @code{rl_completer_word_break_characters} to be
+used to perform the current completion.  The function may choose to set
+@code{rl_completer_word_break_characters} itself.  If the function
+returns @code{NULL}, @code{rl_completer_word_break_characters} is used.
+@end deftypevar
+
+@deftypevar {const char *} rl_completer_quote_characters
+A list of characters which can be used to quote a substring of the line.
+Completion occurs on the entire substring, and within the substring
+@code{rl_completer_word_break_characters} are treated as any other character,
+unless they also appear within this list.
+@end deftypevar
+
+@deftypevar {const char *} rl_filename_quote_characters
+A list of characters that cause a filename to be quoted by the completer
+when they appear in a completed filename.  The default is the null string.
+@end deftypevar
+
+@deftypevar {const char *} rl_special_prefixes
+The list of characters that are word break characters, but should be
+left in @var{text} when it is passed to the completion function.
+Programs can use this to help determine what kind of completing to do.
+For instance, Bash sets this variable to "$@@" so that it can complete
+shell variables and hostnames.
+@end deftypevar
+
+@deftypevar int rl_completion_query_items
+Up to this many items will be displayed in response to a
+possible-completions call.  After that, Readline asks the user for
+confirmation before displaying them.
+The default value is 100.  A negative value 
+indicates that Readline should never ask for confirmation.
+@end deftypevar
+
+@deftypevar {int} rl_completion_append_character
+When a single completion alternative matches at the end of the command
+line, this character is appended to the inserted completion text.  The
+default is a space character (@samp{ }).  Setting this to the null
+character (@samp{\0}) prevents anything being appended automatically.
+This can be changed in application-specific completion functions to
+provide the ``most sensible word separator character'' according to
+an application-specific command line syntax specification.
+It is set to the default before any application-specific completion function
+is called, and may only be changed within such a function.
+@end deftypevar
+
+@deftypevar int rl_completion_suppress_append
+If non-zero, @var{rl_completion_append_character} is not appended to
+matches at the end of the command line, as described above.
+It is set to 0 before any application-specific completion function
+is called, and may only be changed within such a function.
+@end deftypevar
+
+@deftypevar int rl_completion_quote_character
+When Readline is completing quoted text, as delimited by one of the
+characters in @var{rl_completer_quote_characters}, it sets this variable
+to the quoting character found.
+This is set before any application-specific completion function is called.
+@end deftypevar
+
+@deftypevar int rl_completion_suppress_quote
+If non-zero, Readline does not append a matching quote character when
+performing completion on a quoted string.
+It is set to 0 before any application-specific completion function
+is called, and may only be changed within such a function.
+@end deftypevar
+
+@deftypevar int rl_completion_found_quote
+When Readline is completing quoted text, it sets this variable
+to a non-zero value if the word being completed contains or is delimited
+by any quoting characters, including backslashes.
+This is set before any application-specific completion function is called.
+@end deftypevar
+
+@deftypevar int rl_completion_mark_symlink_dirs
+If non-zero, a slash will be appended to completed filenames that are
+symbolic links to directory names, subject to the value of the
+user-settable @var{mark-directories} variable.
+This variable exists so that application-specific completion functions
+can override the user's global preference (set via the
+@var{mark-symlinked-directories} Readline variable) if appropriate.
+This variable is set to the user's preference before any
+application-specific completion function is called, so unless that
+function modifies the value, the user's preferences are honored.
+@end deftypevar
+
+@deftypevar int rl_ignore_completion_duplicates
+If non-zero, then duplicates in the matches are removed.
+The default is 1.
+@end deftypevar
+
+@deftypevar int rl_filename_completion_desired
+Non-zero means that the results of the matches are to be treated as
+filenames.  This is @emph{always} zero when completion is attempted,
+and can only be changed
+within an application-specific completion function.  If it is set to a
+non-zero value by such a function, directory names have a slash appended
+and Readline attempts to quote completed filenames if they contain any
+characters in @code{rl_filename_quote_characters} and
+@code{rl_filename_quoting_desired} is set to a non-zero value.
+@end deftypevar
+
+@deftypevar int rl_filename_quoting_desired
+Non-zero means that the results of the matches are to be quoted using
+double quotes (or an application-specific quoting mechanism) if the
+completed filename contains any characters in
+@code{rl_filename_quote_chars}.  This is @emph{always} non-zero
+when completion is attempted, and can only be changed within an
+application-specific completion function.
+The quoting is effected via a call to the function pointed to
+by @code{rl_filename_quoting_function}.
+@end deftypevar
+
+@deftypevar int rl_attempted_completion_over
+If an application-specific completion function assigned to
+@code{rl_attempted_completion_function} sets this variable to a non-zero
+value, Readline will not perform its default filename completion even
+if the application's completion function returns no matches.
+It should be set only by an application's completion function.
+@end deftypevar
+
+@deftypevar int rl_sort_completion_matches
+If an application sets this variable to 0, Readline will not sort the
+list of completions (which implies that it cannot remove any duplicate
+completions).  The default value is 1, which means that Readline will
+sort the completions and, depending on the value of
+@code{rl_ignore_completion_duplicates}, will attempt to remove duplicate
+matches.
+@end deftypevar
+
+@deftypevar int rl_completion_type
+Set to a character describing the type of completion Readline is currently
+attempting; see the description of @code{rl_complete_internal()}
+(@pxref{Completion Functions}) for the list of characters.
+This is set to the appropriate value before any application-specific
+completion function is called, allowing such functions to present
+the same interface as @code{rl_complete()}.
+@end deftypevar
+
+@deftypevar int rl_completion_invoking_key
+Set to the final character in the key sequence that invoked one of the
+completion functions that call @code{rl_complete_internal()}.  This is
+set to the appropriate value before any application-specific completion
+function is called.
+@end deftypevar
+
+@deftypevar int rl_inhibit_completion
+If this variable is non-zero, completion is inhibited.  The completion
+character will be inserted as any other bound to @code{self-insert}.

+@chapter Command Line Editing
+
+This chapter describes the basic features of the @sc{gnu}
+command line editing interface.
+@ifset BashFeatures
+Command line editing is provided by the Readline library, which is
+used by several different programs, including Bash.
+Command line editing is enabled by default when using an interactive shell,
+unless the @option{--noediting} option is supplied at shell invocation.
+Line editing is also used when using the @option{-e} option to the
+@code{read} builtin command (@pxref{Bash Builtins}).
+By default, the line editing commands are similar to those of Emacs.
+A vi-style line editing interface is also available.
+Line editing can be enabled at any time using the @option{-o emacs} or
+@option{-o vi} options to the @code{set} builtin command
+(@pxref{The Set Builtin}), or disabled using the @option{+o emacs} or 
+@option{+o vi} options to @code{set}.

+
+@node Introduction and Notation
+@section Introduction to Line Editing
+
+The following paragraphs describe the notation used to represent
+keystrokes.
+
+The text @kbd{C-k} is read as `Control-K' and describes the character
+produced when the @key{k} key is pressed while the Control key
+is depressed.
+
+The text @kbd{M-k} is read as `Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the @key{k}
+key is pressed.
+The Meta key is labeled @key{ALT} on many keyboards.
+On keyboards with two keys labeled @key{ALT} (usually to either side of
+the space bar), the @key{ALT} on the left side is generally set to
+work as a Meta key.
+The @key{ALT} key on the right may also be configured to work as a
+Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+
+If you do not have a Meta or @key{ALT} key, or another key working as
+a Meta key, the identical keystroke can be generated by typing @key{ESC}
+@emph{first}, and then typing @key{k}.
+Either process is known as @dfn{metafying} the @key{k} key.
+
+The text @kbd{M-C-k} is read as `Meta-Control-k' and describes the
+character produced by @dfn{metafying} @kbd{C-k}.
+
+In addition, several keys have their own names.  Specifically,
+@key{DEL}, @key{ESC}, @key{LFD}, @key{SPC}, @key{RET}, and @key{TAB} all
+stand for themselves when seen in this text, or in an init file
+(@pxref{Readline Init File}).
+If your keyboard lacks a @key{LFD} key, typing @key{C-j} will
+produce the desired character.
+The @key{RET} key may be labeled @key{Return} or @key{Enter} on
+some keyboards.
+
+@node Readline Interaction
+@section Readline Interaction
+@cindex interaction, readline
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled.  The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line.  Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections.  Then, when you are satisfied with
+the line, you simply press @key{RET}.  You do not have to be at the
+end of the line to press @key{RET}; the entire line is accepted
+regardless of the location of the cursor within the line.

+@node Readline Bare Essentials
+@subsection Readline Bare Essentials
+@cindex notation, readline
+@cindex command editing
+@cindex editing command lines
+
+In order to enter characters into the line, simply type them.  The typed
+character appears where the cursor was, and then the cursor moves one
+space to the right.  If you mistype a character, you can use your
+erase character to back up and delete the mistyped character.
+
+Sometimes you may mistype a character, and
+not notice the error until you have typed several other characters.  In
+that case, you can type @kbd{C-b} to move the cursor to the left, and then
+correct your mistake.  Afterwards, you can move the cursor to the right
+with @kbd{C-f}.
+
+When you add text in the middle of a line, you will notice that characters
+to the right of the cursor are `pushed over' to make room for the text
+that you have inserted.  Likewise, when you delete text behind the cursor,
+characters to the right of the cursor are `pulled back' to fill in the
+blank space created by the removal of the text.  A list of the bare
+essentials for editing the text of an input line follows.
+
+@table @asis
+@item @kbd{C-b}
+Move back one character.
+@item @kbd{C-f}
+Move forward one character.
+@item @key{DEL} or @key{Backspace}
+Delete the character to the left of the cursor.
+@item @kbd{C-d}
+Delete the character underneath the cursor.
+@item @w{Printing characters}
+Insert the character into the line at the cursor.
+@item @kbd{C-_} or @kbd{C-x C-u}
+Undo the last editing command.  You can undo all the way back to an
+empty line.
+@end table
+
+@noindent
+(Depending on your configuration, the @key{Backspace} key might be set to
+delete the character to the left of the cursor and the @key{DEL} key set
+to delete the character underneath the cursor, like @kbd{C-d}, rather
+than the character to the left of the cursor.)
+
+@node Readline Movement Commands
+@subsection Readline Movement Commands
+
+
+The above table describes the most basic keystrokes that you need
+in order to do editing of the input line.  For your convenience, many
+other commands have been added in addition to @kbd{C-b}, @kbd{C-f},
+@kbd{C-d}, and @key{DEL}.  Here are some commands for moving more rapidly
+about the line.
+
+@table @kbd
+@item C-a
+Move to the start of the line.
+@item C-e
+Move to the end of the line.
+@item M-f
+Move forward a word, where a word is composed of letters and digits.
+@item M-b
+Move backward a word.
+@item C-l
+Clear the screen, reprinting the current line at the top.
+@end table
+
+Notice how @kbd{C-f} moves forward a character, while @kbd{M-f} moves
+forward a word.  It is a loose convention that control keystrokes
+operate on characters while meta keystrokes operate on words.
+
+@node Readline Killing Commands
+@subsection Readline Killing Commands
+
+@cindex killing text
+@cindex yanking text
+
+@dfn{Killing} text means to delete the text from the line, but to save
+it away for later use, usually by @dfn{yanking} (re-inserting)
+it back into the line.
+(`Cut' and `paste' are more recent jargon for `kill' and `yank'.)
+
+If the description for a command says that it `kills' text, then you can
+be sure that you can get the text back in a different (or the same)
+place later.
+
+When you use a kill command, the text is saved in a @dfn{kill-ring}.
+Any number of consecutive kills save all of the killed text together, so
+that when you yank it back, you get it all.  The kill
+ring is not line specific; the text that you killed on a previously
+typed line is available to be yanked back later, when you are typing
+another line.
+@cindex kill ring
+
+Here is the list of commands for killing text.
+
+@table @kbd
+@item C-k
+Kill the text from the current cursor position to the end of the line.
+
+@item M-d
+Kill from the cursor to the end of the current word, or, if between
+words, to the end of the next word.
+Word boundaries are the same as those used by @kbd{M-f}.
+
+@item M-@key{DEL}
+Kill from the cursor to the start of the current word, or, if between
+words, to the start of the previous word.
+Word boundaries are the same as those used by @kbd{M-b}.
+
+@item C-w
+Kill from the cursor to the previous whitespace.  This is different than
+@kbd{M-@key{DEL}} because the word boundaries differ.
+
+@end table
+
+Here is how to @dfn{yank} the text back into the line.  Yanking
+means to copy the most-recently-killed text from the kill buffer.
+
+@table @kbd
+@item C-y
+Yank the most recently killed text back into the buffer at the cursor.
+
+@item M-y
+Rotate the kill-ring, and yank the new top.  You can only do this if
+the prior command is @kbd{C-y} or @kbd{M-y}.
+@end table
+
+@node Readline Arguments
+@subsection Readline Arguments
+
+You can pass numeric arguments to Readline commands.  Sometimes the
+argument acts as a repeat count, other times it is the @i{sign} of the
+argument that is significant.  If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction.  For example, to kill text back to the
+start of the line, you might type @samp{M-- C-k}.
+
+The general way to pass numeric arguments to a command is to type meta
+digits before the command.  If the first `digit' typed is a minus
+sign (@samp{-}), then the sign of the argument will be negative.  Once
+you have typed one meta digit to get the argument started, you can type
+the remainder of the digits, and then the command.  For example, to give
+the @kbd{C-d} command an argument of 10, you could type @samp{M-1 0 C-d},
+which will delete the next ten characters on the input line.
+
+@node Searching
+@subsection Searching for Commands in the History
+
+Readline provides commands for searching through the command history
+@ifset BashFeatures
+(@pxref{Bash History Facilities})
+@end ifset
+for lines containing a specified string.
+There are two search modes:  @dfn{incremental} and @dfn{non-incremental}.
+
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, Readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+To search backward in the history for a particular string, type
+@kbd{C-r}.  Typing @kbd{C-s} searches forward through the history.
+The characters present in the value of the @code{isearch-terminators} variable
+are used to terminate an incremental search.
+If that variable has not been assigned a value, the @key{ESC} and
+@kbd{C-J} characters will terminate an incremental search.
+@kbd{C-g} will abort an incremental search and restore the original line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+
+To find other matching entries in the history list, type @kbd{C-r} or
+@kbd{C-s} as appropriate.
+This will search backward or forward in the history for the next
+entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate
+the search and execute that command.
+For instance, a @key{RET} will terminate the search and accept
+the line, thereby executing the command from the history list.
+A movement command will terminate the search, make the last line found
+the current line, and begin editing.
+
+Readline remembers the last incremental search string.  If two
+@kbd{C-r}s are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+
+Non-incremental searches read the entire search string before starting
+to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.
+
+@node Readline Init File
+@section Readline Init File
+@cindex initialization file, readline
+
+Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.
+Any user can customize programs that use Readline by putting
+commands in an @dfn{inputrc} file,
+conventionally in their home directory.
+The name of this
+@ifset BashFeatures
+file is taken from the value of the shell variable @env{INPUTRC}.  If
+@end ifset
+@ifclear BashFeatures
+file is taken from the value of the environment variable @env{INPUTRC}.  If
+@end ifclear
+that variable is unset, the default is @file{~/.inputrc}.  If that
+file does not exist or cannot be read, the ultimate default is
+@file{/etc/inputrc}.
+@ifset BashFeatures
+The @w{@code{bind}} builtin command can also be used to set Readline
+keybindings and variables.
+@xref{Bash Builtins}.
+@end ifset
+
+When a program which uses the Readline library starts up, the
+init file is read, and the key bindings are set.
+
+In addition, the @code{C-x C-r} command re-reads this init file, thus
+incorporating any changes that you might have made to it.
+
+@menu
+* Readline Init File Syntax::	Syntax for the commands in the inputrc file.
+
+* Conditional Init Constructs::	Conditional key bindings in the inputrc file.
+
+* Sample Init File::		An example inputrc file.
+@end menu
+
+@node Readline Init File Syntax
+@subsection Readline Init File Syntax
+
+There are only a few basic constructs allowed in the
+Readline init file.  Blank lines are ignored.
+Lines beginning with a @samp{#} are comments.
+Lines beginning with a @samp{$} indicate conditional
+constructs (@pxref{Conditional Init Constructs}).  Other lines
+denote variable settings and key bindings.
+
+@table @asis
+@item Variable Settings
+You can modify the run-time behavior of Readline by
+altering the values of variables in Readline
+using the @code{set} command within the init file.
+The syntax is simple:
+
+@example
+set @var{variable} @var{value}
+@end example
+
+@noindent
+Here, for example, is how to
+change from the default Emacs-like key binding to use
+@code{vi} line editing commands:
+
+@example
+set editing-mode vi
+@end example
+
+Variable names and values, where appropriate, are recognized without regard
+to case.  Unrecognized variable names are ignored.
+
+Boolean variables (those that can be set to on or off) are set to on if
+the value is null or empty, @var{on} (case-insensitive), or 1.  Any other
+value results in the variable being set to off.
+
+@ifset BashFeatures
+The @w{@code{bind -V}} command lists the current Readline variable names
+and values.  @xref{Bash Builtins}.
+@end ifset
+
+A great deal of run-time behavior is changeable with the following
+variables.
+
+@cindex variables, readline
+@table @code
+
+@item active-region-start-color
+@vindex active-region-start-color
+A string variable that controls the text color and background when displaying
+the text in the active region (see the description of
+@code{enable-active-region} below).
+This string must not take up any physical character positions on the display,
+so it should consist only of terminal escape sequences.
+It is output to the terminal before displaying the text in the active region.
+This variable is reset to the default value whenever the terminal type changes.
+The default value is the string that puts the terminal in standout mode,
+as obtained from the terminal's terminfo description.
+A sample value might be @samp{\e[01;33m}.
+
+@item active-region-end-color
+@vindex active-region-end-color
+A string variable that "undoes" the effects of @code{active-region-start-color}
+and restores "normal" terminal display appearance after displaying text
+in the active region.
+This string must not take up any physical character positions on the display,
+so it should consist only of terminal escape sequences.
+It is output to the terminal after displaying the text in the active region.
+This variable is reset to the default value whenever the terminal type changes.
+The default value is the string that restores the terminal from standout mode,
+as obtained from the terminal's terminfo description.
+A sample value might be @samp{\e[0m}.
+
+@item bell-style
+@vindex bell-style
+Controls what happens when Readline wants to ring the terminal bell.
+If set to @samp{none}, Readline never rings the bell.  If set to
+@samp{visible}, Readline uses a visible bell if one is available.
+If set to @samp{audible} (the default), Readline attempts to ring
+the terminal's bell.
+
+@item bind-tty-special-chars
+@vindex bind-tty-special-chars
+If set to @samp{on} (the default), Readline attempts to bind the control
+characters   treated specially by the kernel's terminal driver to their
+Readline equivalents.
+
+@item blink-matching-paren
+@vindex blink-matching-paren
+If set to @samp{on}, Readline attempts to briefly move the cursor to an
+opening parenthesis when a closing parenthesis is inserted.  The default
+is @samp{off}.
+
+@item colored-completion-prefix
+@vindex colored-completion-prefix
+If set to @samp{on}, when listing completions, Readline displays the
+common prefix of the set of possible completions using a different color.
+The color definitions are taken from the value of the @env{LS_COLORS}
+environment variable.
+If there is a color definition in @env{LS_COLORS} for the custom suffix
+@samp{readline-colored-completion-prefix}, Readline uses this color for
+the common prefix instead of its default.
+The default is @samp{off}.
+
+@item colored-stats
+@vindex colored-stats
+If set to @samp{on}, Readline displays possible completions using different
+colors to indicate their file type.
+The color definitions are taken from the value of the @env{LS_COLORS}
+environment variable.
+The default is @samp{off}.
+
+@item comment-begin
+@vindex comment-begin
+The string to insert at the beginning of the line when the
+@code{insert-comment} command is executed.  The default value
+is @code{"#"}.
+
+@item completion-display-width
+@vindex completion-display-width
+The number of screen columns used to display possible matches
+when performing completion.
+The value is ignored if it is less than 0 or greater than the terminal
+screen width.
+A value of 0 will cause matches to be displayed one per line.
+The default value is -1.
+
+@item completion-ignore-case
+@vindex completion-ignore-case
+If set to @samp{on}, Readline performs filename matching and completion
+in a case-insensitive fashion.
+The default value is @samp{off}.
+
+@item completion-map-case
+@vindex completion-map-case
+If set to @samp{on}, and @var{completion-ignore-case} is enabled, Readline
+treats hyphens (@samp{-}) and underscores (@samp{_}) as equivalent when
+performing case-insensitive filename matching and completion.
+The default value is @samp{off}.
+
+@item completion-prefix-display-length
+@vindex completion-prefix-display-length
+The length in characters of the common prefix of a list of possible
+completions that is displayed without modification.  When set to a
+value greater than zero, common prefixes longer than this value are
+replaced with an ellipsis when displaying possible completions.
+
+@item completion-query-items
+@vindex completion-query-items
+The number of possible completions that determines when the user is
+asked whether the list of possibilities should be displayed.
+If the number of possible completions is greater than or equal to this value,
+Readline will ask whether or not the user wishes to view them;
+otherwise, they are simply listed.
+This variable must be set to an integer value greater than or equal to zero.
+A zero value means Readline should never ask; negative values are
+treated as zero.
+The default limit is @code{100}.
+
+@item convert-meta
+@vindex convert-meta
+If set to @samp{on}, Readline will convert characters with the
+eighth bit set to an @sc{ascii} key sequence by stripping the eighth
+bit and prefixing an @key{ESC} character, converting them to a
+meta-prefixed key sequence.
+The default value is @samp{on}, but
+will be set to @samp{off} if the locale is one that contains
+eight-bit characters.
+This variable is dependent on the @code{LC_CTYPE} locale category, and
+may change if the locale is changed.
+
+@item disable-completion
+@vindex disable-completion
+If set to @samp{On}, Readline will inhibit word completion.
+Completion  characters will be inserted into the line as if they had
+been mapped to @code{self-insert}.  The default is @samp{off}.
+
+@item echo-control-characters
+@vindex echo-control-characters
+When set to @samp{on}, on operating systems that indicate they support it,
+Readline echoes a character corresponding to a signal generated from the
+keyboard.  The default is @samp{on}.
+
+@item editing-mode
+@vindex editing-mode
+The @code{editing-mode} variable controls which default set of
+key bindings is used.  By default, Readline starts up in Emacs editing
+mode, where the keystrokes are most similar to Emacs.  This variable can be
+set to either @samp{emacs} or @samp{vi}.
+
+@item emacs-mode-string
+@vindex emacs-mode-string
+If the @var{show-mode-in-prompt} variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when emacs editing mode is active.  The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the @samp{\1} and @samp{\2} escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+The default is @samp{@@}.
+
+@item enable-active-region
+@vindex enable-active-region
+The @dfn{point} is the current cursor position, and @dfn{mark} refers
+to a saved cursor position (@pxref{Commands For Moving}).
+The text between the point and mark is referred to as the @dfn{region}.
+When this variable is set to @samp{On}, Readline allows certain commands
+to designate the region as @dfn{active}.
+When the region is active, Readline highlights the text in the region using
+the value of the @code{active-region-start-color}, which defaults to the
+string that enables
+the terminal's standout mode.
+The active region shows the text inserted by bracketed-paste and any
+matching text found by incremental and non-incremental history searches.
+The default is @samp{On}.
+
+@item enable-bracketed-paste
+@vindex enable-bracketed-paste
+When set to @samp{On}, Readline configures the terminal to insert each
+paste into the editing buffer as a single string of characters, instead
+of treating each character as if it had been read from the keyboard.
+This is called putting the terminal into @dfn{bracketed paste mode};
+it prevents Readline from executing any editing commands bound to key
+sequences appearing in the pasted text.
+The default is @samp{On}.
+
+@item enable-keypad
+@vindex enable-keypad
+When set to @samp{on}, Readline will try to enable the application
+keypad when it is called.  Some systems need this to enable the
+arrow keys.  The default is @samp{off}.
+
+@item enable-meta-key
+When set to @samp{on}, Readline will try to enable any meta modifier
+key the terminal claims to support when it is called.  On many terminals,
+the meta key is used to send eight-bit characters.
+The default is @samp{on}.
+
+@item expand-tilde
+@vindex expand-tilde
+If set to @samp{on}, tilde expansion is performed when Readline
+attempts word completion.  The default is @samp{off}.
+
+@item history-preserve-point
+@vindex history-preserve-point
+If set to @samp{on}, the history code attempts to place the point (the
+current cursor position) at the
+same location on each history line retrieved with @code{previous-history}
+or @code{next-history}.  The default is @samp{off}.
+
+@item history-size
+@vindex history-size
+Set the maximum number of history entries saved in the history list.
+If set to zero, any existing history entries are deleted and no new entries
+are saved.
+If set to a value less than zero, the number of history entries is not
+limited.
+By default, the number of history entries is not limited.
+If an attempt is made to set @var{history-size} to a non-numeric value,
+the maximum number of history entries will be set to 500.
+
+@item horizontal-scroll-mode
+@vindex horizontal-scroll-mode
+This variable can be set to either @samp{on} or @samp{off}.  Setting it
+to @samp{on} means that the text of the lines being edited will scroll
+horizontally on a single screen line when they are longer than the width
+of the screen, instead of wrapping onto a new screen line.
+This variable is automatically set to @samp{on} for terminals of height 1.
+By default, this variable is set to @samp{off}.
+
+@item input-meta
+@vindex input-meta
+@vindex meta-flag
+If set to @samp{on}, Readline will enable eight-bit input (it
+will not clear the eighth bit in the characters it reads),
+regardless of what the terminal claims it can support.  The
+default value is @samp{off}, but Readline will set it to @samp{on} if the 
+locale contains eight-bit characters.
+The name @code{meta-flag} is a synonym for this variable.
+This variable is dependent on the @code{LC_CTYPE} locale category, and
+may change if the locale is changed.
+
+@item isearch-terminators
+@vindex isearch-terminators
+The string of characters that should terminate an incremental search without
+subsequently executing the character as a command (@pxref{Searching}).
+If this variable has not been given a value, the characters @key{ESC} and
+@kbd{C-J} will terminate an incremental search.
+
+@item keymap
+@vindex keymap
+Sets Readline's idea of the current keymap for key binding commands.
+Built-in @code{keymap} names are
+@code{emacs},
+@code{emacs-standard},
+@code{emacs-meta},
+@code{emacs-ctlx},
+@code{vi},
+@code{vi-move},
+@code{vi-command}, and
+@code{vi-insert}.
+@code{vi} is equivalent to @code{vi-command} (@code{vi-move} is also a
+synonym); @code{emacs} is equivalent to @code{emacs-standard}.
+Applications may add additional names.
+The default value is @code{emacs}.
+The value of the @code{editing-mode} variable also affects the
+default keymap.
+
+@item keyseq-timeout
+Specifies the duration Readline will wait for a character when reading an
+ambiguous key sequence (one that can form a complete key sequence using
+the input read so far, or can take additional input to complete a longer
+key sequence).
+If no input is received within the timeout, Readline will use the shorter
+but complete key sequence.
+Readline uses this value to determine whether or not input is
+available on the current input source (@code{rl_instream} by default).
+The value is specified in milliseconds, so a value of 1000 means that
+Readline will wait one second for additional input.
+If this variable is set to a value less than or equal to zero, or to a
+non-numeric value, Readline will wait until another key is pressed to
+decide which key sequence to complete.
+The default value is @code{500}.
+
+@item mark-directories
+If set to @samp{on}, completed directory names have a slash
+appended.  The default is @samp{on}.
+
+@item mark-modified-lines
+@vindex mark-modified-lines
+This variable, when set to @samp{on}, causes Readline to display an
+asterisk (@samp{*}) at the start of history lines which have been modified.
+This variable is @samp{off} by default.
+
+@item mark-symlinked-directories
+@vindex mark-symlinked-directories
+If set to @samp{on}, completed names which are symbolic links
+to directories have a slash appended (subject to the value of
+@code{mark-directories}).
+The default is @samp{off}.
+
+@item match-hidden-files
+@vindex match-hidden-files
+This variable, when set to @samp{on}, causes Readline to match files whose
+names begin with a @samp{.} (hidden files) when performing filename
+completion.
+If set to @samp{off}, the leading @samp{.} must be
+supplied by the user in the filename to be completed.
+This variable is @samp{on} by default.
+
+@item menu-complete-display-prefix
+@vindex menu-complete-display-prefix
+If set to @samp{on}, menu completion displays the common prefix of the
+list of possible completions (which may be empty) before cycling through
+the list.  The default is @samp{off}.
+
+@item output-meta
+@vindex output-meta
+If set to @samp{on}, Readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence.
+The default is @samp{off}, but Readline will set it to @samp{on} if the
+locale contains eight-bit characters.
+This variable is dependent on the @code{LC_CTYPE} locale category, and
+may change if the locale is changed.
+
+@item page-completions
+@vindex page-completions
+If set to @samp{on}, Readline uses an internal @code{more}-like pager
+to display a screenful of possible completions at a time.
+This variable is @samp{on} by default.
+
+@item print-completions-horizontally
+If set to @samp{on}, Readline will display completions with matches
+sorted horizontally in alphabetical order, rather than down the screen.
+The default is @samp{off}.
+
+@item revert-all-at-newline
+@vindex revert-all-at-newline
+If set to @samp{on}, Readline will undo all changes to history lines
+before returning when @code{accept-line} is executed.  By default,
+history lines may be modified and retain individual undo lists across
+calls to @code{readline()}.  The default is @samp{off}.
+
+@item show-all-if-ambiguous
+@vindex show-all-if-ambiguous
+This alters the default behavior of the completion functions.  If
+set to @samp{on}, 
+words which have more than one possible completion cause the
+matches to be listed immediately instead of ringing the bell.
+The default value is @samp{off}.
+
+@item show-all-if-unmodified
+@vindex show-all-if-unmodified
+This alters the default behavior of the completion functions in
+a fashion similar to @var{show-all-if-ambiguous}.
+If set to @samp{on}, 
+words which have more than one possible completion without any
+possible partial completion (the possible completions don't share
+a common prefix) cause the matches to be listed immediately instead
+of ringing the bell.
+The default value is @samp{off}.
+
+@item show-mode-in-prompt
+@vindex show-mode-in-prompt
+If set to @samp{on}, add a string to the beginning of the prompt
+indicating the editing mode: emacs, vi command, or vi insertion.
+The mode strings are user-settable (e.g., @var{emacs-mode-string}).
+The default value is @samp{off}.
+
+@item skip-completed-text
+@vindex skip-completed-text
+If set to @samp{on}, this alters the default completion behavior when
+inserting a single match into the line.  It's only active when
+performing completion in the middle of a word.  If enabled, Readline
+does not insert characters from the completion that match characters
+after point in the word being completed, so portions of the word
+following the cursor are not duplicated.
+For instance, if this is enabled, attempting completion when the cursor
+is after the @samp{e} in @samp{Makefile} will result in @samp{Makefile}
+rather than @samp{Makefilefile}, assuming there is a single possible
+completion.
+The default value is @samp{off}.
+
+@item vi-cmd-mode-string
+@vindex vi-cmd-mode-string
+If the @var{show-mode-in-prompt} variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when vi editing mode is active and in command mode.
+The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the @samp{\1} and @samp{\2} escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+The default is @samp{(cmd)}.
+
+@item vi-ins-mode-string
+@vindex vi-ins-mode-string
+If the @var{show-mode-in-prompt} variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when vi editing mode is active and in insertion mode.
+The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the @samp{\1} and @samp{\2} escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+The default is @samp{(ins)}.
+
+@item visible-stats
+@vindex visible-stats
+If set to @samp{on}, a character denoting a file's type
+is appended to the filename when listing possible
+completions.  The default is @samp{off}.
+
+@end table
+
+@item Key Bindings
+The syntax for controlling key bindings in the init file is
+simple.  First you need to find the name of the command that you
+want to change.  The following sections contain tables of the command
+name, the default keybinding, if any, and a short description of what
+the command does.
+
+Once you know the name of the command, simply place on a line
+in the init file the name of the key
+you wish to bind the command to, a colon, and then the name of the
+command.
+There can be no space between the key name and the colon -- that will be
+interpreted as part of the key name.
+The name of the key can be expressed in different ways, depending on
+what you find most comfortable.
+
+In addition to command names, Readline allows keys to be bound
+to a string that is inserted when the key is pressed (a @var{macro}).
+
+@ifset BashFeatures
+The @w{@code{bind -p}} command displays Readline function names and
+bindings in a format that can be put directly into an initialization file.
+@xref{Bash Builtins}.
+@end ifset
+
+@table @asis
+@item @w{@var{keyname}: @var{function-name} or @var{macro}}
+@var{keyname} is the name of a key spelled out in English.  For example:
+@example
+Control-u: universal-argument
+Meta-Rubout: backward-kill-word
+Control-o: "> output"
+@end example
+
+In the example above, @kbd{C-u} is bound to the function
+@code{universal-argument},
+@kbd{M-DEL} is bound to the function @code{backward-kill-word}, and
+@kbd{C-o} is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+@samp{> output} into the line).
+
+A number of symbolic character names are recognized while
+processing this key binding syntax:
+@var{DEL},
+@var{ESC},
+@var{ESCAPE},
+@var{LFD},
+@var{NEWLINE},
+@var{RET},
+@var{RETURN},
+@var{RUBOUT},
+@var{SPACE},
+@var{SPC},
+and
+@var{TAB}.
+
+@item @w{"@var{keyseq}": @var{function-name} or @var{macro}}
+@var{keyseq} differs from @var{keyname} above in that strings
+denoting an entire key sequence can be specified, by placing
+the key sequence in double quotes.  Some @sc{gnu} Emacs style key
+escapes can be used, as in the following example, but the
+special character names are not recognized.
+
+@example
+"\C-u": universal-argument
+"\C-x\C-r": re-read-init-file
+"\e[11~": "Function Key 1"
+@end example
+
+In the above example, @kbd{C-u} is again bound to the function
+@code{universal-argument} (just as it was in the first example),
+@samp{@kbd{C-x} @kbd{C-r}} is bound to the function @code{re-read-init-file},
+and @samp{@key{ESC} @key{[} @key{1} @key{1} @key{~}} is bound to insert
+the text @samp{Function Key 1}.
+
+@end table
+
+The following @sc{gnu} Emacs style escape sequences are available when
+specifying key sequences:
+
+@table @code
+@item @kbd{\C-}
+control prefix
+@item @kbd{\M-}
+meta prefix
+@item @kbd{\e}
+an escape character
+@item @kbd{\\}
+backslash
+@item @kbd{\"}
+@key{"}, a double quotation mark
+@item @kbd{\'}
+@key{'}, a single quote or apostrophe
+@end table
+
+In addition to the @sc{gnu} Emacs style escape sequences, a second
+set of backslash escapes is available:
+
+@table @code
+@item \a
+alert (bell)
+@item \b
+backspace
+@item \d
+delete
+@item \f
+form feed
+@item \n
+newline
+@item \r
+carriage return
+@item \t
+horizontal tab
+@item \v
+vertical tab
+@item \@var{nnn}
+the eight-bit character whose value is the octal value @var{nnn}
+(one to three digits)
+@item \x@var{HH}
+the eight-bit character whose value is the hexadecimal value @var{HH}
+(one or two hex digits)
+@end table
+
+When entering the text of a macro, single or double quotes must
+be used to indicate a macro definition.
+Unquoted text is assumed to be a function name.
+In the macro body, the backslash escapes described above are expanded.
+Backslash will quote any other character in the macro text,
+including @samp{"} and @samp{'}.
+For example, the following binding will make @samp{@kbd{C-x} \}
+insert a single @samp{\} into the line:
+@example
+"\C-x\\": "\\"
+@end example
+
+@end table
+
+@node Conditional Init Constructs
+@subsection Conditional Init Constructs
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests.  There are four parser directives used.
+
+@table @code
+@item $if
+The @code{$if} construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+Readline.  The text of the test, after any comparison operator,
+extends to the end of the line;
+unless otherwise noted, no characters are required to isolate it.
+
+@table @code
+@item mode
+The @code{mode=} form of the @code{$if} directive is used to test
+whether Readline is in @code{emacs} or @code{vi} mode.
+This may be used in conjunction
+with the @samp{set keymap} command, for instance, to set bindings in
+the @code{emacs-standard} and @code{emacs-ctlx} keymaps only if
+Readline is starting out in @code{emacs} mode.
+
+@item term
+The @code{term=} form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys.  The word on the right side of the
+@samp{=} is tested against both the full name of the terminal and
+the portion of the terminal name before the first @samp{-}.  This
+allows @code{sun} to match both @code{sun} and @code{sun-cmd},
+for instance.
+
+@item version
+The @code{version} test may be used to perform comparisons against
+specific Readline versions.
+The @code{version} expands to the current Readline version.
+The set of comparison operators includes
+@samp{=} (and @samp{==}), @samp{!=}, @samp{<=}, @samp{>=}, @samp{<},
+and @samp{>}.
+The version number supplied on the right side of the operator consists
+of a major version number, an optional decimal point, and an optional
+minor version (e.g., @samp{7.1}). If the minor version is omitted, it
+is assumed to be @samp{0}.
+The operator may be separated from the string @code{version} and
+from the version number argument by whitespace.
+The following example sets a variable if the Readline version being used
+is 7.0 or newer:
+@example
+$if version >= 7.0
+set show-mode-in-prompt on
+$endif
+@end example
+
+@item application
+The @var{application} construct is used to include
+application-specific settings.  Each program using the Readline
+library sets the @var{application name}, and you can test for
+a particular value. 
+This could be used to bind key sequences to functions useful for
+a specific program.  For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+@example
+$if Bash
+# Quote the current or previous word
+"\C-xq": "\eb\"\ef\""
+$endif
+@end example
+
+@item variable
+The @var{variable} construct provides simple equality tests for Readline
+variables and values.
+The permitted comparison operators are @samp{=}, @samp{==}, and @samp{!=}.
+The variable name must be separated from the comparison operator by
+whitespace; the operator may be separated from the value on the right hand
+side by whitespace.
+Both string and boolean variables may be tested. Boolean variables must be
+tested against the values @var{on} and @var{off}.
+The following example is equivalent to the @code{mode=emacs} test described
+above:
+@example
+$if editing-mode == emacs
+set show-mode-in-prompt on
+$endif
+@end example
+@end table
+
+@item $endif
+This command, as seen in the previous example, terminates an
+@code{$if} command.
+
+@item $else
+Commands in this branch of the @code{$if} directive are executed if
+the test fails.
+
+@item $include
+This directive takes a single filename as an argument and reads commands
+and bindings from that file.
+For example, the following directive reads from @file{/etc/inputrc}:
+@example
+$include /etc/inputrc
+@end example
+@end table
+
+@node Sample Init File
+@subsection Sample Init File
+
+Here is an example of an @var{inputrc} file.  This illustrates key
+binding, variable assignment, and conditional syntax.

+Move `forward' through the history list, fetching the next command.
+
+@item beginning-of-history (M-<)
+Move to the first line in the history.
+

+This command sets the region to the matched text and activates the mark.
+
+@item forward-search-history (C-s)
+Search forward starting at the current line and moving `down' through
+the history as necessary.  This is an incremental search.
+This command sets the region to the matched text and activates the mark.
+
+@item non-incremental-reverse-search-history (M-p)
+Search backward starting at the current line and moving `up'

+for a string supplied by the user.
+The search string may match anywhere in a history line.
+
+@item non-incremental-forward-search-history (M-n)
+Search forward starting at the current line and moving `down'
+through the history as necessary using a non-incremental search
+for a string supplied by the user.
+The search string may match anywhere in a history line.
+
+@item history-search-forward ()
+Search forward through the history for the string of characters
+between the start of the current line and the point.
+The search string must match at the beginning of a history line.
+This is a non-incremental search.
+By default, this command is unbound.

+With an argument @var{n},
+insert the @var{n}th word from the previous command (the words
+in the previous command begin with word 0).  A negative argument
+inserts the @var{n}th word from the end of the previous command.
+Once the argument @var{n} is computed, the argument is extracted

+
+@item yank-last-arg (M-. or M-_)
+Insert last argument to the previous command (the last word of the

+With a numeric argument, behave exactly like @code{yank-nth-arg}.
+Successive calls to @code{yank-last-arg} move back through the history
+list, inserting the last word (or the word specified by the argument to
+the first call) of each line in turn.
+Any numeric argument supplied to these successive calls determines

+@node Commands For Text
+@subsection Commands For Changing Text
+
+@ftable @code
+
+@item @i{end-of-file} (usually C-d)
+The character indicating end-of-file as set, for example, by
+@code{stty}.  If this character is read when there are no characters
+on the line, and point is at the beginning of the line, Readline
+interprets it as the end of input and returns @sc{eof}.
+
+@item delete-char (C-d)
+Delete the character at point.  If this function is bound to the
+same character as the tty @sc{eof} character, as @kbd{C-d}
+commonly is, see above for the effects.
+
+@item backward-delete-char (Rubout)
+Delete the character behind the cursor.  A numeric argument means
+to kill the characters instead of deleting them.
+
+@item forward-backward-delete-char ()
+Delete the character under the cursor, unless the cursor is at the
+end of the line, in which case the character behind the cursor is
+deleted.  By default, this is not bound to a key.
+
+@item quoted-insert (C-q or C-v)
+Add the next character typed to the line verbatim.  This is
+how to insert key sequences like @kbd{C-q}, for example.
+
+@ifclear BashFeatures
+@item tab-insert (M-@key{TAB})
+Insert a tab character.
+@end ifclear
+
+@item self-insert (a, b, A, 1, !, @dots{})
+Insert yourself.
+
+@item bracketed-paste-begin ()
+This function is intended to be bound to the "bracketed paste" escape
+sequence sent by some terminals, and such a binding is assigned by default.
+It allows Readline to insert the pasted text as a single unit without treating
+each character as if it had been read from the keyboard.  The characters
+are inserted as if each one was bound to @code{self-insert} instead of
+executing any editing commands.
+
+Bracketed paste sets the region (the characters between point and the mark)
+to the inserted text. It uses the concept of an @emph{active mark}: when the
+mark is active, Readline redisplay uses the terminal's standout mode to
+denote the region.
+
+@item transpose-chars (C-t)
+Drag the character before the cursor forward over
+the character at the cursor, moving the
+cursor forward as well.  If the insertion point
+is at the end of the line, then this
+transposes the last two characters of the line.
+Negative arguments have no effect.
+
+@item transpose-words (M-t)
+Drag the word before point past the word after point,
+moving point past that word as well.
+If the insertion point is at the end of the line, this transposes
+the last two words on the line.
+
+@item upcase-word (M-u)
+Uppercase the current (or following) word.  With a negative argument,
+uppercase the previous word, but do not move the cursor.
+
+@item downcase-word (M-l)
+Lowercase the current (or following) word.  With a negative argument,
+lowercase the previous word, but do not move the cursor.
+
+@item capitalize-word (M-c)
+Capitalize the current (or following) word.  With a negative argument,
+capitalize the previous word, but do not move the cursor.
+
+@item overwrite-mode ()
+Toggle overwrite mode.  With an explicit positive numeric argument,
+switches to overwrite mode.  With an explicit non-positive numeric
+argument, switches to insert mode.  This command affects only
+@code{emacs} mode; @code{vi} mode does overwrite differently.
+Each call to @code{readline()} starts in insert mode.
+
+In overwrite mode, characters bound to @code{self-insert} replace
+the text at point rather than pushing the text to the right.
+Characters bound to @code{backward-delete-char} replace the character
+before point with a space.
+
+By default, this command is unbound.

+If the command is followed by digits, executing @code{universal-argument}
+again ends the numeric argument, but is otherwise ignored.
+As a special case, if this command is immediately followed by a

+@section Programmable Completion
+@cindex programmable completion
+
+When word completion is attempted for an argument to a command for
+which a completion specification (a @var{compspec}) has been defined
+using the @code{complete} builtin (@pxref{Programmable Completion Builtins}),
+the programmable completion facilities are invoked. 
+
+First, the command name is identified.
+If a compspec has been defined for that command, the
+compspec is used to generate the list of possible completions for the word.
+If the command word is the empty string (completion attempted at the
+beginning of an empty line), any compspec defined with
+the @option{-E} option to @code{complete} is used.
+If the command word is a full pathname, a compspec for the full
+pathname is searched for first.
+If no compspec is found for the full pathname, an attempt is made to
+find a compspec for the portion following the final slash.
+If those searches do not result in a compspec, any compspec defined with
+the @option{-D} option to @code{complete} is used as the default.
+If there is no default compspec, Bash attempts alias expansion
+on the command word as a final resort, and attempts to find a compspec
+for the command word from any successful expansion 
+
+Once a compspec has been found, it is used to generate the list of
+matching words.
+If a compspec is not found, the default Bash completion
+described above (@pxref{Commands For Completion}) is performed.
+
+First, the actions specified by the compspec are used.
+Only matches which are prefixed by the word being completed are
+returned.
+When the @option{-f} or @option{-d} option is used for filename or
+directory name completion, the shell variable @env{FIGNORE} is
+used to filter the matches.
+@xref{Bash Variables}, for a description of @env{FIGNORE}.
+
+Any completions specified by a filename expansion pattern to the
+@option{-G} option are generated next.
+The words generated by the pattern need not match the word being completed.
+The @env{GLOBIGNORE} shell variable is not used to filter the matches,
+but the @env{FIGNORE} shell variable is used.
+
+Next, the string specified as the argument to the @option{-W} option
+is considered.
+The string is first split using the characters in the @env{IFS}
+special variable as delimiters.
+Shell quoting is honored within the string, in order to provide a
+mechanism for the words to contain shell metacharacters or characters
+in the value of @env{IFS}.
+Each word is then expanded using
+brace expansion, tilde expansion, parameter and variable expansion,
+command substitution, and arithmetic expansion,
+as described above (@pxref{Shell Expansions}).
+The results are split using the rules described above
+(@pxref{Word Splitting}).
+The results of the expansion are prefix-matched against the word being
+completed, and the matching words become the possible completions.
+
+After these matches have been generated, any shell function or command
+specified with the @option{-F} and @option{-C} options is invoked.
+When the command or function is invoked, the @env{COMP_LINE},
+@env{COMP_POINT}, @env{COMP_KEY}, and @env{COMP_TYPE} variables are
+assigned values as described above (@pxref{Bash Variables}).
+If a shell function is being invoked, the @env{COMP_WORDS} and
+@env{COMP_CWORD} variables are also set.
+When the function or command is invoked, the first argument ($1) is the
+name of the command whose arguments are being completed, the
+second argument ($2) is the word being completed, and the third argument
+($3) is the word preceding the word being completed on the current command
+line.
+No filtering of the generated completions against the word being completed
+is performed; the function or command has complete freedom in generating
+the matches.
+
+Any function specified with @option{-F} is invoked first.
+The function may use any of the shell facilities, including the
+@code{compgen} and @code{compopt} builtins described below
+(@pxref{Programmable Completion Builtins}), to generate the matches.
+It must put the possible completions in the @env{COMPREPLY} array
+variable, one per array element.
+
+Next, any command specified with the @option{-C} option is invoked
+in an environment equivalent to command substitution.
+It should print a list of completions, one per line, to
+the standard output.
+Backslash may be used to escape a newline, if necessary.
+
+After all of the possible completions are generated, any filter
+specified with the @option{-X} option is applied to the list.
+The filter is a pattern as used for pathname expansion; a @samp{&}
+in the pattern is replaced with the text of the word being completed.
+A literal @samp{&} may be escaped with a backslash; the backslash
+is removed before attempting a match.
+Any completion that matches the pattern will be removed from the list.
+A leading @samp{!} negates the pattern; in this case any completion
+not matching the pattern will be removed.
+If the @code{nocasematch} shell option
+(see the description of @code{shopt} in @ref{The Shopt Builtin})
+is enabled, the match is performed without regard to the case
+of alphabetic characters.
+
+Finally, any prefix and suffix specified with the @option{-P} and @option{-S}
+options are added to each member of the completion list, and the result is
+returned to the Readline completion code as the list of possible
+completions.
+
+If the previously-applied actions do not generate any matches, and the
+@option{-o dirnames} option was supplied to @code{complete} when the
+compspec was defined, directory name completion is attempted. 
+
+If the @option{-o plusdirs} option was supplied to @code{complete} when
+the compspec was defined, directory name completion is attempted and any
+matches are added to the results of the other actions.
+
+By default, if a compspec is found, whatever it generates is returned to
+the completion code as the full set of possible completions.
+The default Bash completions are not attempted, and the Readline default
+of filename completion is disabled.
+If the @option{-o bashdefault} option was supplied to @code{complete} when
+the compspec was defined, the default Bash completions are attempted
+if the compspec generates no matches.
+If the @option{-o default} option was supplied to @code{complete} when the
+compspec was defined, Readline's default completion will be performed
+if the compspec (and, if attempted, the default Bash completions)
+generate no matches.
+
+When a compspec indicates that directory name completion is desired,
+the programmable completion functions force Readline to append a slash
+to completed names which are symbolic links to directories, subject to
+the value of the @var{mark-directories} Readline variable, regardless
+of the setting of the @var{mark-symlinked-directories} Readline variable.
+
+There is some support for dynamically modifying completions.  This is
+most useful when used in combination with a default completion specified
+with @option{-D}.  It's possible for shell functions executed as completion
+handlers to indicate that completion should be retried by returning an
+exit status of 124.  If a shell function returns 124, and changes
+the compspec associated with the command on which completion is being
+attempted (supplied as the first argument when the function is executed),
+programmable completion restarts from the beginning, with an
+attempt to find a new compspec for that command.  This allows a set of
+completions to be built dynamically as completion is attempted, rather than
+being loaded all at once.
+
+For instance, assuming that there is a library of compspecs, each kept in a
+file corresponding to the name of the command, the following default
+completion function would load completions dynamically:
+
+@example
+_completion_loader()
+@{
+    . "/etc/bash_completion.d/$1.sh" >/dev/null 2>&1 && return 124
+@}
+complete -D -F _completion_loader -o bashdefault -o default
+@end example
+
+@node Programmable Completion Builtins
+@section Programmable Completion Builtins
+@cindex completion builtins
+
+Three builtin commands are available to manipulate the programmable completion
+facilities: one to specify how the arguments to a particular command are to
+be completed, and two to modify the completion as it is happening.
+
+@table @code
+@item compgen
+@btindex compgen
+@example
+@code{compgen [@var{option}] [@var{word}]}
+@end example
+
+Generate possible completion matches for @var{word} according to
+the @var{option}s, which may be any option accepted by the
+@code{complete}
+builtin with the exception of @option{-p} and @option{-r}, and write
+the matches to the standard output.
+When using the @option{-F} or @option{-C} options, the various shell variables
+set by the programmable completion facilities, while available, will not
+have useful values.
+
+The matches will be generated in the same way as if the programmable
+completion code had generated them directly from a completion specification
+with the same flags.
+If @var{word} is specified, only those completions matching @var{word}
+will be displayed.
+
+The return value is true unless an invalid option is supplied, or no
+matches were generated.
+
+@item complete
+@btindex complete
+@example
+@code{complete [-abcdefgjksuv] [-o @var{comp-option}] [-DEI] [-A @var{action}] [-G @var{globpat}]

+[-P @var{prefix}] [-S @var{suffix}] @var{name} [@var{name} @dots{}]}
+@code{complete -pr [-DEI] [@var{name} @dots{}]}
+@end example
+
+Specify how arguments to each @var{name} should be completed.
+If the @option{-p} option is supplied, or if no options are supplied, existing
+completion specifications are printed in a way that allows them to be
+reused as input.
+The @option{-r} option removes a completion specification for
+each @var{name}, or, if no @var{name}s are supplied, all
+completion specifications.
+The @option{-D} option indicates that other supplied options and actions should
+apply to the ``default'' command completion; that is, completion attempted
+on a command for which no completion has previously been defined.
+The @option{-E} option indicates that other supplied options and actions should
+apply to ``empty'' command completion; that is, completion attempted on a 
+blank line.
+The @option{-I} option indicates that other supplied options and actions should
+apply to completion on the initial non-assignment word on the line, or after a
+command delimiter such as @samp{;} or @samp{|}, which is usually command
+name completion.
+If multiple options are supplied, the @option{-D} option takes precedence
+over @option{-E}, and both take precedence over @option{-I}.
+If any of @option{-D}, @option{-E}, or @option{-I} are supplied, any other
+@var{name} arguments are ignored; these completions only apply to the case
+specified by the option.
+
+The process of applying these completion specifications when word completion
+is attempted is described above (@pxref{Programmable Completion}).
+
+Other options, if specified, have the following meanings.
+The arguments to the @option{-G}, @option{-W}, and @option{-X} options
+(and, if necessary, the @option{-P} and @option{-S} options)
+should be quoted to protect them from expansion before the
+@code{complete} builtin is invoked.
+
+
+@table @code
+@item -o @var{comp-option}
+The @var{comp-option} controls several aspects of the compspec's behavior
+beyond the simple generation of completions.
+@var{comp-option} may be one of: 
+
+@table @code
+
+@item bashdefault
+Perform the rest of the default Bash completions if the compspec
+generates no matches.
+
+@item default
+Use Readline's default filename completion if the compspec generates
+no matches.
+
+@item dirnames
+Perform directory name completion if the compspec generates no matches.
+
+@item filenames
+Tell Readline that the compspec generates filenames, so it can perform any
+filename-specific processing (like adding a slash to directory names,
+quoting special characters, or suppressing trailing spaces).
+This option is intended to be used with shell functions specified
+with @option{-F}.
+
+@item noquote
+Tell Readline not to quote the completed words if they are filenames
+(quoting filenames is the default).
+
+@item nosort
+Tell Readline not to sort the list of possible completions alphabetically.
+
+@item nospace
+Tell Readline not to append a space (the default) to words completed at
+the end of the line.

+
+@node A Programmable Completion Example
+@section A Programmable Completion Example
+
+The most common way to obtain additional completion functionality beyond
+the default actions @code{complete} and @code{compgen} provide is to use
+a shell function and bind it to a particular command using @code{complete -F}.
+
+The following function provides completions for the @code{cd} builtin.
+It is a reasonably good example of what shell functions must do when
+used for completion.  This function uses the word passed as @code{$2}
+to determine the directory name to complete.  You can also use the
+@code{COMP_WORDS} array variable; the current word is indexed by the
+@code{COMP_CWORD} variable.
+
+The function relies on the @code{complete} and @code{compgen} builtins
+to do much of the work, adding only the things that the Bash @code{cd}
+does beyond accepting basic directory names:
+tilde expansion (@pxref{Tilde Expansion}),
+searching directories in @var{$CDPATH}, which is described above
+(@pxref{Bourne Shell Builtins}),
+and basic support for the @code{cdable_vars} shell option
+(@pxref{The Shopt Builtin}).
+@code{_comp_cd} modifies the value of @var{IFS} so that it contains only
+a newline to accommodate file names containing spaces and tabs --
+@code{compgen} prints the possible completions it generates one per line.
+
+Possible completions go into the @var{COMPREPLY} array variable, one
+completion per array element.  The programmable completion system retrieves
+the completions from there when the function returns.
+
+@example
+# A completion function for the cd builtin
+# based on the cd completion function from the bash_completion package
+_comp_cd()
+@{
+    local IFS=$' \t\n'    # normalize IFS
+    local cur _skipdot _cdpath
+    local i j k
+
+    # Tilde expansion, which also expands tilde to full pathname
+    case "$2" in
+    \~*)    eval cur="$2" ;;
+    *)      cur=$2 ;;
+    esac
+
+    # no cdpath or absolute pathname -- straight directory completion
+    if [[ -z "$@{CDPATH:-@}" ]] || [[ "$cur" == @@(./*|../*|/*) ]]; then
+        # compgen prints paths one per line; could also use while loop
+        IFS=$'\n'
+        COMPREPLY=( $(compgen -d -- "$cur") )
+        IFS=$' \t\n'
+    # CDPATH+directories in the current directory if not in CDPATH
+    else
+        IFS=$'\n'
+        _skipdot=false
+        # preprocess CDPATH to convert null directory names to .
+        _cdpath=$@{CDPATH/#:/.:@}
+        _cdpath=$@{_cdpath//::/:.:@}
+        _cdpath=$@{_cdpath/%:/:.@}
+        for i in $@{_cdpath//:/$'\n'@}; do
+            if [[ $i -ef . ]]; then _skipdot=true; fi
+            k="$@{#COMPREPLY[@@]@}"
+            for j in $( compgen -d -- "$i/$cur" ); do
+                COMPREPLY[k++]=$@{j#$i/@}        # cut off directory
+            done
+        done
+        $_skipdot || COMPREPLY+=( $(compgen -d -- "$cur") )
+        IFS=$' \t\n'
+    fi
+
+    # variable names if appropriate shell option set and no completions
+    if shopt -q cdable_vars && [[ $@{#COMPREPLY[@@]@} -eq 0 ]]; then
+        COMPREPLY=( $(compgen -v -- "$cur") )
+    fi
+
+    return 0
+@}
+@end example
+
+We install the completion function using the @option{-F} option to
+@code{complete}:
+
+@example
+# Tell readline to quote appropriate and append slashes to directories;
+# use the bash default completion for other arguments
+complete -o filenames -o nospace -o bashdefault -F _comp_cd cd
+@end example
+
+@noindent
+Since we'd like Bash and Readline to take care of some
+of the other details for us, we use several other options to tell Bash
+and Readline what to do.  The @option{-o filenames} option tells Readline
+that the possible completions should be treated as filenames, and quoted
+appropriately.  That option will also cause Readline to append a slash to
+filenames it can determine are directories (which is why we might want to
+extend @code{_comp_cd} to append a slash if we're using directories found
+via @var{CDPATH}: Readline can't tell those completions are directories).
+The @option{-o nospace} option tells Readline to not append a space
+character to the directory name, in case we want to append to it.
+The @option{-o bashdefault} option brings in the rest of the "Bash default"
+completions -- possible completions that Bash adds to the default Readline
+set.  These include things like command name completion, variable completion
+for words beginning with @samp{$} or @samp{$@{}, completions containing pathname
+expansion patterns (@pxref{Filename Expansion}), and so on.
+
+Once installed using @code{complete}, @code{_comp_cd} will be called every
+time we attempt word completion for a @code{cd} command.
+
+Many more examples -- an extensive collection of completions for most of
+the common GNU, Unix, and Linux commands -- are available as part of the
+bash_completion project.  This is installed by default on many GNU/Linux
+distributions.  Originally written by Ian Macdonald, the project now lives
+at @url{https://github.com/scop/bash-completion/}.  There are ports for
+other systems such as Solaris and Mac OS X.
+
+An older version of the bash_completion package is distributed with bash
+in the @file{examples/complete} subdirectory.

+Subject: new readline example
+Message-ID: <14094.12094.527305.199695@mrclean.Stanford.EDU>
+
+Chet,
+
+I've been using readline 4.0. Specifically, I've been using the perl
+version Term::ReadLine::Gnu. It works great.
+
+Anyway, I've been playing around the alternate interface and I wanted
+to contribute a little C program, callback.c, to you that you could
+use as an example of the alternate interface in the /examples
+directory of the readline distribution.
+
+My example shows how, using the alternate interface, you can
+interactively change the prompt (which is very nice imo). Also, I
+point out that you must roll your own terminal setting when using the
+alternate interface because readline depreps (using your parlance) the
+terminal while in the user callback. I try to demostrate what I mean
+with an example. I've included the program below.
+
+To compile, I just put the program in the examples directory and made
+the appropriate changes to the EXECUTABLES and OBJECTS line and added
+an additional target 'callback'.
+
+I compiled on my Sun Solaris2.6 box using Sun's cc.
+
+Let me know what you think.
+

+/* This little examples demonstrates the alternate interface to using readline.
+ * In the alternate interface, the user maintains control over program flow and
+ * only calls readline when STDIN is readable. Using the alternate interface,
+ * you can do anything else while still using readline (like talking to a
+ * network or another program) without blocking.
+ *
+ * Specifically, this program highlights two importants features of the
+ * alternate interface. The first is the ability to interactively change the
+ * prompt, which can't be done using the regular interface since rl_prompt is
+ * read-only.
+ * 
+ * The second feature really highlights a subtle point when using the alternate
+ * interface. That is, readline will not alter the terminal when inside your
+ * callback handler. So let's so, your callback executes a user command that
+ * takes a non-trivial amount of time to complete (seconds). While your
+ * executing the command, the user continues to type keystrokes and expects them
+ * to be re-echoed on the new prompt when it returns. Unfortunately, the default
+ * terminal configuration doesn't do this. After the prompt returns, the user
+ * must hit one additional keystroke and then will see all of his previous
+ * keystrokes. To illustrate this, compile and run this program. Type "sleep" at
+ * the prompt and then type "bar" before the prompt returns (you have 3
+ * seconds). Notice how "bar" is re-echoed on the prompt after the prompt
+ * returns? This is what you expect to happen. Now comment out the 4 lines below
+ * the line that says COMMENT LINE BELOW. Recompile and rerun the program and do
+ * the same thing. When the prompt returns, you should not see "bar". Now type
+ * "f", see how "barf" magically appears? This behavior is un-expected and not
+ * desired.

+
+Hi Arnold,
+in a process of fixing of strftime() in libraries on Atari ST I grabbed
+some pieces of code from your own strftime.  When doing that it came
+to mind that your weeknumber() function compiles a little bit nicer
+in the following form:
+/*
+ * firstweekday is 0 if starting in Sunday, non-zero if in Monday
+ */
+{
+    return (timeptr->tm_yday - timeptr->tm_wday +
+	    (firstweekday ? (timeptr->tm_wday ? 8 : 1) : 7)) / 7;
+}
+How nicer it depends on a compiler, of course, but always a tiny bit.
+
+   Cheers,
+   Michal

+
+   Suppress extern inline with HP-UX cc, as it appears to be broken; see
+   <https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
+
+   Suppress extern inline with Sun C in standards-conformance mode, as it
+   mishandles inline functions that call each other.  E.g., for 'inline void f
+   (void) { } inline void g (void) { f (); }', c99 incorrectly complains
+   'reference to static identifier "f" in extern inline function'.
+   This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
+
+   Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
+   on configurations that mistakenly use 'static inline' to implement
+   functions or macros in standard C headers like <ctype.h>.  For example,
+   if isdigit is mistakenly implemented via a static inline function,
+   a program containing an extern inline function that calls isdigit
+   may not work since the C standard prohibits extern inline functions
+   from calling static functions (ISO C 99 section 6.7.4.(3).
+   This bug is known to occur on:
+
+     OS X 10.8 and earlier; see:
+     https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
+
+     DragonFly; see
+     http://muscles.dragonflybsd.org/bulk/bleeding-edge-potential/latest-per-pkg/ah-tty-0.3.12.log
+
+     FreeBSD; see:
+     https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
+
+   OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
+   for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
+   Assume DragonFly and FreeBSD will be similar.
+
+   GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+   inline semantics, unless -fgnu89-inline is used.  It defines a macro
+   __GNUC_STDC_INLINE__ to indicate this situation or a macro
+   __GNUC_GNU_INLINE__ to indicate the opposite situation.
+   GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
+   semantics but warns, unless -fgnu89-inline is used:
+     warning: C99 inline functions are not supported; using GNU89
+     warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
+   It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.

+dnl Modified for bash use by Chet Ramey <chet.ramey@case.edu>, 2021
+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: BASH_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
+dnl    default (if it is not specified or empty) is 'no-libtool'.
+dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
+dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl    depending on --{enable,disable}-{shared,static} and on the presence of
+dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
+dnl    $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl    implementations (in libc or libintl) without the ngettext() function
+dnl    will be ignored.  If NEEDSYMBOL is specified and is
+dnl    'need-formatstring-macros', then GNU gettext implementations that don't
+dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries.  If empty,
+dnl    the value '$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl    and used.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl    Catalog format: none
+dnl    Catalog extension: none
+dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.

+dnl From Bruno Haible and Sam Steingold.
+
+dnl Sets the HOST_CPU variable to the canonical name of the CPU.
+dnl Sets the HOST_CPU_C_ABI variable to the canonical name of the CPU with its
+dnl C language ABI (application binary interface).
+dnl Also defines __${HOST_CPU}__ and __${HOST_CPU_C_ABI}__ as C macros in
+dnl config.h.
+dnl
+dnl This canonical name can be used to select a particular assembly language
+dnl source file that will interoperate with C code on the given host.
+dnl
+dnl For example:
+dnl * 'i386' and 'sparc' are different canonical names, because code for i386
+dnl   will not run on SPARC CPUs and vice versa. They have different
+dnl   instruction sets.
+dnl * 'sparc' and 'sparc64' are different canonical names, because code for
+dnl   'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code
+dnl   contains 32-bit instructions, whereas 'sparc64' code contains 64-bit
+dnl   instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit
+dnl   mode, but not both.
+dnl * 'mips' and 'mipsn32' are different canonical names, because they use
+dnl   different argument passing and return conventions for C functions, and
+dnl   although the instruction set of 'mips' is a large subset of the
+dnl   instruction set of 'mipsn32'.
+dnl * 'mipsn32' and 'mips64' are different canonical names, because they use
+dnl   different sizes for the C types like 'int' and 'void *', and although
+dnl   the instruction sets of 'mipsn32' and 'mips64' are the same.
+dnl * The same canonical name is used for different endiannesses. You can
+dnl   determine the endianness through preprocessor symbols:
+dnl   - 'arm': test __ARMEL__.
+dnl   - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL.
+dnl   - 'powerpc64': test _BIG_ENDIAN vs. _LITTLE_ENDIAN.
+dnl * The same name 'i386' is used for CPUs of type i386, i486, i586
+dnl   (Pentium), AMD K7, Pentium II, Pentium IV, etc., because
+dnl   - Instructions that do not exist on all of these CPUs (cmpxchg,
+dnl     MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your
+dnl     assembly language source files use such instructions, you will

+dnl Inspired by
+dnl https://github.com/linux-test-project/ltp/blob/master/testcases/open_posix_testsuite/conformance/interfaces/pthread_rwlock_rdlock/2-2.c
+dnl by Intel Corporation.
+
+dnl Test whether in a situation where
+dnl   - an rwlock is taken by a reader and has a writer waiting,
+dnl   - an additional reader requests the lock,
+dnl   - the waiting writer and the requesting reader threads have the same
+dnl     priority,
+dnl the requesting reader thread gets blocked, so that at some point the
+dnl waiting writer can acquire the lock.
+dnl Without such a guarantee, when there a N readers and each of the readers
+dnl spends more than 1/Nth of the time with the lock held, there is a high
+dnl probability that the waiting writer will not get the lock in a given finite
+dnl time, a phenomenon called "writer starvation".
+dnl Without such a guarantee, applications have a hard time avoiding writer
+dnl starvation.
+dnl
+dnl POSIX:2017 makes this requirement only for implementations that support TPS
+dnl (Thread Priority Scheduling) and only for the scheduling policies SCHED_FIFO
+dnl and SCHED_RR, see
+dnl http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_rwlock_rdlock.html
+dnl but this test verifies the guarantee regardless of TPS and regardless of
+dnl scheduling policy.
+dnl Glibc currently does not provide this guarantee, see

+"Parse option arguments.\n"
+"    \n"

+"    as options.\n"
+"    \n"
+"    OPTSTRING contains the option letters to be recognized; if a letter\n"
+"    is followed by a colon, the option is expected to have an argument,\n"
+"    which should be separated from it by white space.\n"
+"    \n"

+"    shell variable $name, initializing name if it does not exist, and\n"
+"    the index of the next argument to be processed into the shell\n"
+"    variable OPTIND.  OPTIND is initialized to 1 each time the shell or\n"
+"    a shell script is invoked.  When an option requires an argument,\n"
+"    getopts places that argument into the shell variable OPTARG.\n"
+"    \n"
+"    getopts reports errors in one of two ways.  If the first character\n"

+"    seen, getopts places the option character found into OPTARG.  If a\n"

+"    sets OPTARG to the option character found.  If getopts is not in\n"
+"    silent mode, and an invalid option is seen, getopts places '?' into\n"
+"    NAME and unsets OPTARG.  If a required argument is not found, a '?'\n"
+"    is placed in NAME, OPTARG is unset, and a diagnostic message is\n"
+"    printed.\n"

+Subject: X bitmap for bash
+
+        Since other GNU software comes with its very own X bitmap, I
+     thought it was about time bash had one too & here it is!  To use,
+     stick the stuff after my signature in a file <path>/bash.xbm.  If
+     using a twm window manager, insert the lines:
+
+IconDirectory           "<path>"
+Icons {
+        "<xterm title>" "bash.xbm"
+}
+        in your ~/.twmrc file.  The <xterm title> can be a prefix, so if
+     you have titles "bash@machine", the prefix "bash" will do.  I'm not
+     familiar enough with other window managers, but they should be
+     similar.
+
+        If you like it, you're welcome to it...
+
+        Simon.

+# Configuration subroutine to validate and canonicalize a configuration type.

+# If it is invalid, we print an error message on stderr and exit with code 1.
+# Otherwise, we print the canonical config type on stdout and succeed.

+
+# This file is supposed to be the same for all GNU packages
+# and recognize all the CPU types, system types and aliases
+# that are meaningful with *any* GNU software.
+# Each package is responsible for reporting which valid configurations
+# it does not support.  The user should be able to distinguish
+# a failure to support a valid configuration from a meaningless
+# configuration.
+
+# The goal of this file is to map all the various variations of a given
+# machine specification into a single specification in the form:
+#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
+# or in some cases, the newer four-part form:
+#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
+# It is wrong to echo any other type of specification.
+
+# The "shellcheck disable" line above the timestamp inhibits complaints
+# about features and limitations of the classic Bourne shell that were
+# superseded or lifted in POSIX.  However, this script identifies a wide
+# variety of pre-POSIX systems that do not have POSIX shells at all, and
+# even some reasonably current systems (Solaris 10 as case-in-point) still
+# have a pre-POSIX /bin/sh.

+ * man2html will add links to the converted manpages. The function add_links
+ * is used for that. At the moment it will add links as follows, where
+ *     indicates what should match to start with:
+ * ^^^
+ * Recognition           Item            Link
+ * ----------------------------------------------------------
+ * name(*)               Manpage         ../man?/name.*
+ *     ^
+ * name@hostname         Email address   mailto:name@hostname
+ *     ^
+ * method://string       URL             method://string
+ *       ^^^
+ * www.host.name         WWW server      http://www.host.name
+ * ^^^^
+ * ftp.host.name         FTP server      ftp://ftp.host.name
+ * ^^^^
+ * <file.h>              Include file    file:/usr/include/file.h
+ *      ^^^
+ *
+ * Since man2html does not check if manpages, hosts or email addresses exist,
+ * some links might not work. For manpages, some extra checks are performed
+ * to make sure not every () pair creates a link. Also out of date pages
+ * might point to incorrect places.
+ *
+ * The program will not allow users to get system specific files, such as
+ * /etc/passwd. It will check that "man" is part of the specified file and
+ * that  "/../" isn't. Even if someone manages to get such file, man2html will
+ * handle it like a manpage and will usually not produce any output (or crash).
+ *
+ * If you find any bugs when normal manpages are converted, please report
+ * them to me (rcb5@win.tue.nl) after you have checked that man(1) can handle
+ * the manpage correct.
+ *
+ * Known bugs and missing features:
+ *
+ *  * Equations are not converted at all.
+ *  * Tables are converted but some features are not possible in html.
+ *  * The tabbing environment is converted by counting characters and adding
+ *    spaces. This might go wrong (outside <PRE>)
+ *  * Some pages look better if man2html works in troff mode, especially pages
+ *    with tables. You can decide at compile time which made you want to use.
+ *
+ *    -DNROFF=0     troff mode
+ *    -DNROFF=1     nroff mode   (default)
+ *
+ *    if you install both modes, you should compile with the correct CGIBASE.
+ *  * Some manpages rely on the fact that troff/nroff is used to convert
+ *    them and use features which are not descripted in the man manpages.
+ *    (definitions, calculations, conditionals, requests). I can't guarantee
+ *    that all these features work on all manpages. (I didn't have the
+ *    time to look through all the available manpages.)

+Usage: $program [OPTION]... FILE...
+  or:  texi2pdf [OPTION]... FILE...
+  or:  pdftexi2dvi [OPTION]... FILE...
+
+Run each Texinfo or (La)TeX FILE through TeX in turn until all
+cross-references are resolved, building all indices.  The directory
+containing each FILE is searched for included files.  The suffix of FILE
+is used to determine its language ((La)TeX or Texinfo).  To process
+(e)plain TeX files, set the environment variable LATEX=tex.
+
+When invoked as \`texi2pdf' or given the option --pdf generate PDF output.
+Otherwise, generate DVI.
+
+General options:
+  -D, --debug         turn on shell debugging (set -x)
+  -h, --help          display this help and exit successfully
+  -o, --output=OFILE  leave output in OFILE; only one input FILE is allowed
+  -q, --quiet         no output unless errors
+  -v, --version       display version information and exit successfully
+  -V, --verbose       report on what is done
+  --max-iterations=N  don't process files more than N times [$max_iters]
+  --mostly-clean      remove auxiliary files or directories from
+                          previous runs (but not the output)
+
+Output format:
+      --dvi     output a DVI file [default]
+      --dvipdf  output a PDF file via DVI (using a dvi-to-pdf program)
+      --html    output an HTML file from LaTeX, using HeVeA
+      --info    output an Info file from LaTeX, using HeVeA
+  -p, --pdf     use pdftex or pdflatex for processing
+      --ps      output a PostScript file via DVI (using dvips)
+      --text    output a plain text file from LaTeX, using HeVeA
+
+TeX tuning:
+  -E, --expand               macro expansion using makeinfo
+  -I DIR                     search DIR for Texinfo files
+  -l, --language=LANG        specify LANG for FILE, either latex or texinfo
+      --no-line-error        do not pass --file-line-error to TeX
+      --shell-escape         pass --shell-escape to TeX
+      --src-specials         pass --src-specials to TeX
+      --translate-file=FILE  use given charset translation file for TeX
+  -t, --command=CMD          insert CMD in copy of input file
+
+Build modes:
+  --build=MODE         specify the treatment of auxiliary files [$build_mode]
+      --tidy           same as --build=tidy
+  -c, --clean          same as --build=clean
+      --build-dir=DIR  specify where the tidy compilation is performed;
+                         implies --tidy;
+                         defaults to TEXI2DVI_BUILD_DIRECTORY [$build_dir]
+
+The MODE specifies where the TeX compilation takes place, and, as a
+consequence, how auxiliary files are treated.  The build mode can also
+be set using the environment variable TEXI2DVI_BUILD_MODE.
+
+Valid values of MODE are:
+  \`local'      compile in the current directory, leaving all the auxiliary
+               files around.  This is the traditional TeX use.
+  \`tidy'       compile in a local *.t2d directory, where the auxiliary files
+               are left.  Output files are copied back to the original file.
+  \`clean'      same as \`tidy', but remove the auxiliary directory afterwards.
+               Every compilation therefore requires the full cycle.
+
+The values of these environment variables are used to run the
+corresponding commands, if they are set:
+
+  BIBER BIBTEX DVIPDF DVIPS EGREP HEVEA LATEX MAKEINDEX MAKEINFO
+  PDFLATEX PDFTEX SED T4HT TEX TEX4HT TEXINDEX TEXINDY THUMBPDF_CMD
+
+Regarding --dvipdf, if DVIPDF is not set in the environment, the
+following programs are looked for (in this order): dvipdfmx dvipdfm
+dvipdf dvi2pdf dvitopdf.
+
+If Texinfo is installed on your site, then the command
+
+  info texi2dvi
+  
+should give you access to more documentation.

+# Control of Page layout:

+# 1.) For small changes, it is often enough to change the value of
+#     some global string/hash/array variables
+# 2.) For larger changes, reimplement one of the T2H_DEFAULT_<fnc>* routines,
+#     give them another name, and assign them to the respective
+#     $T2H_<fnc> variable.
+
+# As a general interface, the hashes T2H_HREF, T2H_NAME, T2H_NODE hold 
+# href, html-name, node-name of
+# This     -- current section (resp. html page)
+# Top      -- top page ($T2H_TOP_FILE)
+# Contents -- Table of contents
+# Overview -- Short table of contents
+# Index    -- Index page
+# About    -- page which explain "navigation buttons"
+# First    -- first node 
+# Last     -- last node
+#
+# Whether or not the following hash values are set, depends on the context 
+# (all values are w.r.t. 'This' section)
+# Next        -- next node of texinfo
+# Prev        -- previous node of texinfo
+# Up          -- up node of texinfo
+# Forward     -- next node in reading order
+# Back        -- previous node in reading order
+# FastForward -- if leave node, up and next, else next node
+# FastBackward-- if leave node, up and prev, else prev node

+
+/* DYNAMIC VARIABLES
+
+   These are variables whose values are generated anew each time they are
+   referenced.  These are implemented using a pair of function pointers
+   in the struct variable: assign_func, which is called from bind_variable
+   and, if arrays are compiled into the shell, some of the functions in
+   arrayfunc.c, and dynamic_value, which is called from find_variable.
+
+   assign_func is called from bind_variable_internal, if
+   bind_variable_internal discovers that the variable being assigned to
+   has such a function.  The function is called as
+	SHELL_VAR *temp = (*(entry->assign_func)) (entry, value, ind)
+   and the (SHELL_VAR *)temp is returned as the value of bind_variable.  It
+   is usually ENTRY (self).  IND is an index for an array variable, and
+   unused otherwise.
+
+   dynamic_value is called from find_variable_internal to return a `new'
+   value for the specified dynamic variable.  If this function is NULL,
+   the variable is treated as a `normal' shell variable.  If it is not,
+   however, then this function is called like this:
+	tempvar = (*(var->dynamic_value)) (var);
+
+   Sometimes `tempvar' will replace the value of `var'.  Other times, the
+   shell will simply use the string value.  Pretty object-oriented, huh?
+
+   Be warned, though: if you `unset' a special variable, it loses its
+   special meaning, even if you subsequently set it.
+
+   The special assignment code would probably have been better put in
+   subst.c: do_assignment_internal, in the same style as
+   stupidly_hack_special_variables, but I wanted the changes as
+   localized as possible.  */
