+$FUNCTION shopt_builtin
+$SHORT_DOC shopt [-pqsu] [-o] [optname ...]
+Set and unset shell options.
+
+Change the setting of each shell option OPTNAME. Without any option
+arguments, list all shell options with an indication of whether or not each
+is set.
+
+Options:
+ -o restrict OPTNAMEs to those defined for use with `set -o'
+ -p print each shell option with an indication of its status
+ -q suppress output
+ -s enable (set) each OPTNAME
+ -u disable (unset) each OPTNAME
+
+Exit Status:
+Returns success if OPTNAME is enabled; fails if an invalid option is
+given or OPTNAME is disabled.

+If the command word is the empty string (completion attempted at the

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.

+.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 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:

+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.
+.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
+.PP
+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''.

+key sequences is

+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
+.PP
+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 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 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\-ignore\-case (Off)
+If set to \fBOn\fP, readline performs filename matching and completion
+in a case\-insensitive fashion.
+.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, the user is asked whether
+or not he 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).
+.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 editing\-mode (emacs)
+Controls whether readline begins with a set of key bindings similar
+to emacs or vi.
+.B editing\-mode
+can be set to either
+.B emacs
+or
+.BR vi .
+.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 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 (0)
+Set the maximum number of history entries saved in the history list. If
+set to zero, the number of entries in the history list is not limited.
+.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.
+.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.
+.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 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, unless the leading `.' is
+supplied by the user in the filename to be completed.
+.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.
+.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 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
+.PP
+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 $if
+construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+readline. The text of the test extends to the end of the line;
+no characters are required to isolate it.
+.RS
+.IP \fBmode\fP
+The \fBmode=\fP form of the \fB$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 \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 Bash:
+.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
+.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
+.PP
+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
+.PP
+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.

+position (the \fIpoint\fP).
+This is a non-incremental search.
+.TP
+.B history\-search\-backward
+Search backward through the history for the string of characters
+between the start of the current line and the point.
+This is a non-incremental search.
+.TP
+.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 ,

+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
+as if the "!\fIn\fP" history expansion had been specified.
+.TP
+.B
+yank\-last\-arg (M\-.\^, M\-_\^)
+Insert the last argument to the previous command (the last word of

+Kill from point 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 \fBforward\-word\fP.
+.TP
+.B backward\-kill\-word (M\-Rubout)
+Kill the word behind point.
+Word boundaries are the same as those used by \fBbackward\-word\fP.
+.TP
+.B 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.
+.TP
+.B 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.
+.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.
+.TP
+.B copy\-forward\-word
+Copy the word following point to the kill buffer.
+The word boundaries are the same as \fBforward\-word\fP.
+.TP
+.B yank (C\-y)
+Yank the top of the kill ring into the buffer at point.
+.TP
+.B yank\-pop (M\-y)
+Rotate the kill ring, and yank the new top. Only works following
+.B yank
+or
+.BR yank\-pop .
+.PD
+.SS Numeric Arguments
+.PP
+.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
+.PP
+.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.
+.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
+Deletes the character under the cursor if not at the beginning or
+end of the line (like \fBdelete-char\fP).
+If at the end of the line, behaves identically to
+\fBpossible-completions\fP.

+Stop saving the characters typed into the current keyboard macro
+and store the definition.
+.TP
+.B 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.

+Abort the current editing command and
+ring the terminal's bell (subject to the setting of
+.BR bell\-style ).
+.TP
+.B do\-uppercase\-version (M\-a, M\-b, M\-\fIx\fP, ...)
+If the metafied character \fIx\fP is lowercase, run the command
+that is bound to the corresponding uppercase character.
+.TP
+.B prefix\-meta (ESC)
+Metafy the next character typed.
+.SM
+.B ESC
+.B f
+is equivalent to
+.BR Meta\-f .
+.TP
+.B undo (C\-_, C\-x C\-u)
+Incremental undo, separately remembered for each line.
+.TP
+.B revert\-line (M\-r)
+Undo all changes made to this line. This is like executing the
+.B undo
+command enough times to return the line to its initial state.
+.TP
+.B tilde\-expand (M\-&)
+Perform tilde expansion on the current word.
+.TP
+.B set\-mark (C\-@, M\-<space>)
+Set the mark to the point. If a
+numeric argument is supplied, the mark is set to that position.
+.TP
+.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 count 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 count 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
+.B comment\-begin
+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.
+.TP
+.B 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 \fIinputrc\fP file.
+.TP
+.B 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 \fIinputrc\fP file.
+.TP
+.B 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 \fIinputrc\fP file.
+.TP
+.B emacs\-editing\-mode (C\-e)
+When in
+.B vi

+.PD
+.SH DEFAULT KEY BINDINGS
+.LP
+The following is a list of the default emacs and vi bindings.
+Characters with the eighth bit set are written as M\-<character>, and
+are referred to as
+.I metafied
+characters.
+The printable ASCII characters not mentioned in the list of emacs
+standard bindings are bound to the
+.B self\-insert
+function, which just inserts the given character into the input line.
+In vi insertion mode, all characters not specifically mentioned are
+bound to
+.BR self\-insert .
+Characters assigned to signal generation by
+.IR stty (1)
+or the terminal driver, such as C-Z or C-C,
+retain that function.
+Upper and lower case metafied characters are bound to the same function in
+the emacs mode meta keymap.
+The remaining characters are unbound, which causes readline
+to ring the bell (subject to the setting of the

+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,

+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

+@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.
+

+@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 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 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 his 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}.
+
+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 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}, Readline attempts to bind the control characters
+treated specially by the kernel's terminal driver to their Readline
+equivalents.
+
+@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-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-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 this value,
+Readline will ask the user whether or not he wishes to view
+them; otherwise, they are simply listed.
+This variable must be set to an integer value greater than or equal to 0.
+A negative value means Readline should never ask.
+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}.
+
+@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 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 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 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, the number of entries in the history list is not limited.
+
+@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. 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}. The name @code{meta-flag} is a
+synonym for this variable.
+
+@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.
+Acceptable @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{emacs} is
+equivalent to @code{emacs-standard}. The default value is @code{emacs}.
+The value of the @code{editing-mode} variable also affects the
+default keymap.
+
+@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, unless the leading @samp{.} is
+supplied by the user in the filename to be completed.
+This variable is @samp{on} by default.
+
+@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}.
+
+@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 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 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 above example, @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 extends to the end of the line;
+no characters are required to isolate it.
+
+@table @code
+@item mode
+The @code{mode=} form of the @code{$if} directive is used to test
+whether Readline is in @code{emacs} or @code{vi} mode.
+This may be used in conjunction
+with the @samp{set keymap} command, for instance, to set bindings in
+the @code{emacs-standard} and @code{emacs-ctlx} keymaps only if
+Readline is starting out in @code{emacs} mode.
+
+@item term
+The @code{term=} form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys. The word on the right side of the
+@samp{=} is tested against both the full name of the terminal and
+the portion of the terminal name before the first @samp{-}. This
+allows @code{sun} to match both @code{sun} and @code{sun-cmd},
+for instance.
+
+@item application
+The @var{application} construct is used to include
+application-specific settings. Each program using the Readline
+library sets the @var{application name}, and you can test for
+a particular value.
+This could be used to bind key sequences to functions useful for
+a specific program. For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+@example
+$if Bash
+# Quote the current or previous word
+"\C-xq": "\eb\"\ef\""
+$endif
+@end example
+@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

+@node Programmable Completion
+@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.
+
+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.
+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 is the
+name of the command whose arguments are being completed, the
+second argument is the word being completed, and the third argument
+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.
+
+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.
+
+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 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
+
+@node Programmable Completion Builtins
+@section Programmable Completion Builtins
+@cindex completion builtins
+
+Two builtin commands are available to manipulate the programmable completion
+facilities.
+
+@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}] [-DE] [-A @var{action}] [-G @var{globpat}] [-W @var{wordlist}]
+[-F @var{function}] [-C @var{command}] [-X @var{filterpat}]
+[-P @var{prefix}] [-S @var{suffix}] @var{name} [@var{name} @dots{}]}
+@code{complete -pr [-DE] [@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 the remaining 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 the remaining options and actions should
+apply to ``empty'' command completion; that is, completion attempted on a
+blank line.
+
+The process of applying these completion specifications when word completion
+is attempted is described above (@pxref{Programmable Completion}). The
+@option{-D} option takes precedence over @option{-E}.
+
+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 nospace
+Tell Readline not to append a space (the default) to words completed at
+the end of the line.
+
+@item 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.
+
+@end table
+
+@item -A @var{action}
+The @var{action} may be one of the following to generate a list of possible
+completions:
+
+@table @code
+@item alias
+Alias names. May also be specified as @option{-a}.
+
+@item arrayvar
+Array variable names.

+Help topics as accepted by the @code{help} builtin (@pxref{Bash Builtins}).
+
+@item hostname
+Hostnames, as taken from the file specified by the
+@env{HOSTFILE} shell variable (@pxref{Bash Variables}).
+
+@item job
+Job names, if job control is active. May also be specified as @option{-j}.
+
+@item keyword
+Shell reserved words. May also be specified as @option{-k}.
+

+
+@item user
+User names. May also be specified as @option{-u}.
+
+@item variable

+@end table
+
+@item -G @var{globpat}
+The filename expansion pattern @var{globpat} is expanded to generate
+the possible completions.
+
+@item -W @var{wordlist}
+The @var{wordlist} is split using the characters in the
+@env{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.
+
+@item -C @var{command}
+@var{command} is executed in a subshell environment, and its output is
+used as the possible completions.
+
+@item -F @var{function}
+The shell function @var{function} is executed in the current shell
+environment.
+When it finishes, the possible completions are retrieved from the value
+of the @env{COMPREPLY} array variable.
+
+@item -X @var{filterpat}
+@var{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
+@var{filterpat} is removed from the list.
+A leading @samp{!} in @var{filterpat} negates the pattern; in this
+case, any completion not matching @var{filterpat} is removed.
+
+@item -P @var{prefix}
+@var{prefix} is added at the beginning of each possible completion
+after all other options have been applied.
+
+@item -S @var{suffix}
+@var{suffix} is appended to each possible completion
+after all other options have been applied.
+@end table
+
+The return value is true unless an invalid option is supplied, an option
+other than @option{-p} or @option{-r} is supplied without a @var{name}
+argument, an attempt is made to remove a completion specification for
+a @var{name} for which no specification exists, or
+an error occurs adding a completion specification.
+
+@item compopt
+@btindex compopt
+@example
+@code{compopt} [-o @var{option}] [-DE] [+o @var{option}] [@var{name}]
+@end example
+Modify completion options for each @var{name} according to the
+@var{option}s, or for the currently-execution completion if no @var{name}s
+are supplied.
+If no @var{option}s are given, display the completion options for each
+@var{name} or the current completion.
+The possible values of @var{option} are those valid for the @code{complete}
+builtin described above.
+The @option{-D} option indicates that the remaining options 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 the remaining options should
+apply to ``empty'' command completion; that is, completion attempted on a
+blank line.
+
+The @option{-D} option takes precedence over @option{-E}.
+
+The return value is true unless an invalid option is supplied, an attempt
+is made to modify the options for a @var{name} for which no completion
+specification exists, or an output error occurs.
