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