検索しましたman bash
が、現在のすべてのキーバインディングをリストするものは見つかりませんでしたbind -x
。それを実行する方法はありますか? 次のことを試しました:
$ bind -x '"\C-`":"echo hello"'
# test binding: press CTRL+`
hello
# Binding works!
$ bind -p | grep 'hello'
# no output
$ bind -S
# no output
bind -x
それで、現在アクティブなものをすべてリスト表示する方法はありますか?

私の場合、bash では空の出力を返しました。ただし、大文字の「P」は機能します。
bind - すべての関数名(およびバインディング)を表示します
これにより、関数へのバインディングのみが提供されます。
bind -P
説明
-P List current readline function names and bindings.
-p Display readline function names and bindings in such a
way that they can be re-read.
サンプル出力
set-mark can be found on "\C-@", "\e ".
shell-expand-line can be found on "\e\C-e".
start-kbd-macro can be found on "\C-x(".
tilde-expand can be found on "\e&".
transpose-chars can be found on "\C-t".
transpose-words can be found on "\et".
undo can be found on "\C-x\C-u", "\C-_".
unix-line-discard can be found on "\C-u".
unix-word-rubout can be found on "\C-w".
upcase-word can be found on "\eu".
yank can be found on "\C-y".
yank-last-arg can be found on "\e.", "\e_".
yank-nth-arg can be found on "\e\C-y".
yank-pop can be found on "\ey".
bind - すべての文字列挿入を表示する
これにより、任意のキーストロークのバインディングが提供されます。
bind -S
-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.
サンプル出力:
\el outputs ls -lrtha --color=always\C-j
\ep outputs pwd\C-j
\er outputs docker rm
\ew outputs wget --no-check-certificate \"\"\e[D
マニュアルページ
驚くほどマニュアルページを見つけるのが難しいので、ここに掲載します。
bind [-m keymap] [-lpsvPSVX]
bind [-m keymap] [-q function] [-u function] [-r keyseq]
bind [-m keymap] -f filename
bind [-m keymap] -x keyseq:shell-command
bind [-m keymap] keyseq:function-name
bind readline-command
Display current readline key and function bindings, bind a key
sequence to a readline function or macro, or set a readline
variable. Each non-option argument is a command as it would
appear in .inputrc, but each binding or command must be passed
as a separate argument; e.g., '"\C-x\C-r": re-read-init-file'.
Options, if supplied, have the following meanings:
-m keymap
Use keymap as the keymap to be affected by the subsequent
bindings. Acceptable keymap names are emacs,
emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move,
vi-command, and vi-insert. vi is equivalent to
vi-command; emacs is equivalent to emacs-standard.
-l List the names of all readline functions.
-p Display readline function names and bindings in such a
way that they can be re-read.
-P List current readline function names and bindings.
-s Display readline key sequences bound to macros and the
strings they output in such a way that they can be re-
read.
-S Display readline key sequences bound to macros and the
strings they output.
-v Display readline variable names and values in such a way
that they can be re-read.
-V List current readline variable names and values.
-f filename
Read key bindings from filename.
-q function
Query about which keys invoke the named function.
-u function
Unbind all keys bound to the named function.
-r keyseq
Remove any current binding for keyseq.
-x keyseq:shell-command
Cause shell-command to be executed whenever keyseq is
entered. When shell-command is executed, the shell sets
the READLINE_LINE variable to the contents of the
readline line buffer and the READLINE_POINT variable to
the current location of the insertion point. If the
executed command changes the value of READLINE_LINE or
READLINE_POINT, those new values will be reflected in the
editing state.
-X List all key sequences bound to shell commands and the
associated commands in a format that can be reused as
input.
The return value is 0 unless an unrecognized option is given or
an error occurred.
