+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.
+
+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', 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 2.50 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 supports 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. You can specify an installation prefix other
+than '/usr/local' by giving 'configure' the option '--prefix=PATH', or
+by specifying a value for the 'DESTDIR' 'make' variable when running
+'make install'.
+
+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.
+
+Specifying the System Type
+==========================
+
+There may be some features 'configure' can not figure out automatically,
+but need 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-purify'
+ Define this to use the Purify memory allocation checker from
+ Rational Software.
+
+'--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
+and linked, 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-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 'disabled-builtins',
+'direxpand-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-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-separate-helpfiles'
+ Use external files for the documentation displayed by the 'help'
+ builtin instead of storing the text internally.
+
+'--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-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.
