+.SH DESCRIPTION
+.LP
+.B readline
+will read a line from the terminal
+and return it, using
+.B prompt
+as a prompt. If
+.B prompt
+is \fBNULL\fP or the empty string, no prompt is issued.
+The line returned is allocated with
+.IR malloc (3);
+the caller must free it when finished. The line returned
+has the final newline removed, so only the text of the line
+remains.
+.LP
+.B readline
+offers editing capabilities while the user is entering the
+line.
+By default, the line editing commands
+are similar to those of emacs.
+A vi\-style line editing interface is also available.
+.LP
+This manual page describes only the most basic use of \fBreadline\fP.
+Much more functionality is available; see
+\fIThe GNU Readline Library\fP and \fIThe GNU History Library\fP
+for additional information.
+.SH RETURN VALUE
+.LP
+.B readline
+returns the text of the line read. A blank line
+returns the empty string. If
+.B EOF
+is encountered while reading a line, and the line is empty,
+.B NULL
+is returned. If an
+.B EOF
+is read with a non\-empty line, it is
+treated as a newline.
+.SH NOTATION
+.LP
+An 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.
+.SH INITIALIZATION FILE
+.LP
+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
+.B INPUTRC
+environment 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
+init file is read, and the key bindings and variables are set.
+There are only a few basic constructs allowed in the
+readline init 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.
+Each program using this library may add its own commands
+and bindings.
+.PP
+For example, placing
+.RS
+.PP
+M\-Control\-u: universal\-argument
+.RE
+or
+.RS
+C\-Meta\-u: universal\-argument
+.RE
+.sp
+into the
+.I inputrc
+would make M\-C\-u execute the readline command
+.IR universal\-argument .
+.PP
+The following symbolic character names are recognized while
+processing key bindings:
+.IR DEL ,
+.IR ESC ,
+.IR ESCAPE ,
+.IR LFD ,
+.IR NEWLINE ,
+.IR RET ,
+.IR RETURN ,
+.IR RUBOUT ,
+.IR SPACE ,
+.IR SPC ,
+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).
+.PP
+.SS 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.
+The name and key sequence are separated by a colon. There can be no
+whitespace between the name and the colon.
+.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
+The full set of GNU Emacs style escape sequences available when specifying
+key sequences is
+.RS
+.PD 0
+.TP
+.B \eC\-
+control prefix
+.TP
+.B \eM\-
+meta prefix
+.TP
+.B \ee
+an escape character
+.TP
+.B \e\e
+backslash
+.TP
+.B \e"
+literal ", a double quote
+.TP
+.B \e'
+literal ', a single quote
+.RE
+.PD
+.PP
+In addition to the GNU Emacs style escape sequences, a second
+set of backslash escapes is available:
+.RS
+.PD 0
+.TP
+.B \ea
+alert (bell)
+.TP
+.B \eb
+backspace
+.TP
+.B \ed
+delete
+.TP
+.B \ef
+form feed
+.TP
+.B \en
+newline
+.TP
+.B \er
+carriage return
+.TP
+.B \et
+horizontal tab
+.TP
+.B \ev
+vertical tab
+.TP
+.B \e\fInnn\fP
+the eight-bit character whose value is the octal value \fInnn\fP
+(one to three digits)
+.TP
+.B \ex\fIHH\fP
+the eight-bit character whose value is the hexadecimal value \fIHH\fP
+(one or two hex digits)
+.RE
+.PD
+.PP
+When entering the text of a macro, single or double quotes should
+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 '.
+.PP
+.B Bash
+allows the current readline key bindings to be displayed or modified
+with the
+.B bind
+builtin command. The editing mode may be switched during interactive
+use by using the
+.B \-o
+option to the
+.B set
+builtin command. Other programs using this library provide
+similar mechanisms. The
+.I inputrc
+file may be edited and re-read if a program does not provide
+any other means to incorporate new bindings.
+.SS 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
+.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 (the default), 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 in \fBvi\fP mode when the
+.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 negative value causes readline to never ask.
+.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 it with 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 not limited.
+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 clear the eighth bit in 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 legal keymap names is
+\fIemacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move,
+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 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 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
+.SH SEARCHING
+Readline provides commands for searching through the command history
+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.
+To search backward in the history for a particular string, type
+\fBC\-r\fP. Typing \fBC\-s\fP searches forward through the history.
+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 \fIEscape\fP and
+\fBC\-J\fP characters will terminate an incremental search.
+\fBC\-G\fP 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 \fBC\-s\fP or
+\fBC\-r\fP as appropriate.
+This will search backward or forward in the history for the next
+line 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 newline 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.
+.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.
+.SH EDITING COMMANDS
+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.
+.PP
+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 argument,
+as if the "!$" history expansion had been specified.
+.PD
+.SS Commands for Changing Text
+.PD 0
+.TP
+.B \fIend\-of\-file\fP (usually C\-d)
+The character indicating end-of-file as set, for example, by
+.if t \f(CWstty\fP.
+.if n ``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
+.SM
+.BR EOF .
+.TP
+.B delete\-char (C\-d)
+Delete the character at point.
+If this function is bound to the
+same character as the tty \fBEOF\fP character, as \fBC\-d\fP
+commonly is, see above for the effects.
+.TP
+.B backward\-delete\-char (Rubout)
+Delete the character behind the cursor. When given a numeric argument,
+save the deleted text on the kill ring.
+.TP
+.B 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.
+.TP
+.B quoted\-insert (C\-q, C\-v)
+Add the next character that you type to the line verbatim. This is
+how to insert characters like \fBC\-q\fP, for example.
+.TP
+.B tab\-insert (M-TAB)
+Insert a tab character.
+.TP
+.B self\-insert (a,\ b,\ A,\ 1,\ !,\ ...)
+Insert the character typed.
+.TP
+.B transpose\-chars (C\-t)
+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.
+.TP
+.B transpose\-words (M\-t)
+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.
+.TP
+.B upcase\-word (M\-u)
+Uppercase the current (or following) word. With a negative argument,
+uppercase the previous word, but do not move point.
+.TP
+.B downcase\-word (M\-l)
+Lowercase the current (or following) word. With a negative argument,
+lowercase the previous word, but do not move point.
+.TP
+.B capitalize\-word (M\-c)
+Capitalize the current (or following) word. With a negative argument,
+capitalize the previous word, but do not move point.
+.TP
+.B 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
+\fBemacs\fP mode; \fBvi\fP mode does overwrite differently.
+Each call to \fIreadline()\fP starts in insert mode.
+In overwrite mode, characters bound to \fBself\-insert\fP replace
+the text at point rather than pushing the text to the right.
+Characters bound to \fBbackward\-delete\-char\fP replace the character
+before point with a space. By default, this command is unbound.

+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.
+.TP
+.B delete\-horizontal\-space (M\-\e)
+Delete all spaces and tabs around point.
+.TP
+.B kill\-region
+Kill the text between the point and \fImark\fP (saved cursor position).
+This text is referred to as the \fIregion\fP.
+.TP
+.B copy\-region\-as\-kill
+Copy the text in the region to the kill buffer.
+.TP
+.B copy\-backward\-word
+Copy the word before point to the kill buffer.
+The word boundaries are the same as \fBbackward\-word\fP.

+.PD
+.SS Numeric Arguments
+.PD 0
+.TP
+.B 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.
+.TP
+.B 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
+.B 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 or 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.
+.PD
+.SS Completing
+.PD 0
+.TP
+.B complete (TAB)
+Attempt to perform completion on the text before point.
+The actual completion performed is application-specific.
+.BR Bash ,
+for instance, attempts completion treating the text as a variable
+(if the text begins with \fB$\fP), username (if the text begins with
+\fB~\fP), hostname (if the text begins with \fB@\fP), or
+command (including aliases and functions) in turn. If none
+of these produces a match, filename completion is attempted.
+.BR Gdb ,
+on the other hand,
+allows completion of program functions and variables, and
+only attempts filename completion under certain circumstances.
+.TP
+.B 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 \fBcompletion-display-width\fP, the value of
+the environment variable
+.SM
+.BR COLUMNS ,
+or the screen width, in that order.
+.TP
+.B insert\-completions (M\-*)
+Insert all completions of the text before point
+that would have been generated by
+\fBpossible\-completions\fP.
+.TP
+.B menu\-complete
+Similar to \fBcomplete\fP, but replaces the word to be completed
+with a single match from the list of possible completions.
+Repeated execution of \fBmenu\-complete\fP 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 \fBbell\-style\fP)
+and the original text is restored.
+An argument of \fIn\fP moves \fIn\fP 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 \fBTAB\fP, but is unbound
+by default.
+.TP
+.B menu\-complete\-backward
+Identical to \fBmenu\-complete\fP, but moves backward through the list
+of possible completions, as if \fBmenu\-complete\fP had been given a
+negative argument. This command is unbound by default.
+.TP
+.B delete\-char\-or\-list

+.B 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.
+.TP
+.B 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.
+.TP
+.B 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.
+.TP
+.B 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\-[.
+.TP
+.B insert\-comment (M\-#)
+Without a numeric argument, the value of the readline
+.B 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 \fBcomment\-begin\fP, the value is inserted, otherwise
+the characters in \fBcomment-begin\fP 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

+makes 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.
