基本上可利用 readline的功能達到
readline的介紹 請"man bash" 或是"info readline"
bind -P 可列出現有的readline binding function
bind -B List current readline variable names and values.

可先由bind -P 來參考並學習他們binding的設定，以協助自行設定

而個人的設定檔是位於 ~/.inputrc中，若沒有請自行建立。記得做任何修改後，鍵入C-x C-r 讓readline重新讀取該設定檔
比如說 以下設定可以輸入ctrl-x l 即可以執行 "ls -l"
"\C-xl": "\C-e\C-u ls -l \C-M"

加入\C-e\C-u 是可以讓目前的輸入清空
最後的 C-M 就等於是enter的意思
若你的keymap與我們不一樣，可以自行修改

所以你可以將要經常輸入的指令 加入~/.inputrc中隨時都可以加入移除
尤其是一些較長的指令時
我個人是蠻喜歡使用F9~F12這個區段 僅供您參考

像我常常用C-z 暫停某些程序 (比如修改script時，存檔後，跳出來測試，而不用結束編輯程式)
而為了方便再跳回 我就將 C-xz設成 fg 則可以很方便的切換shell跟當前的process
"\C-xz": "\C-e\C-u fg \C-M"



另外比較特別但不常用的功能是在readline中 還可以加入like C prepocessor的條件式判斷
可以根據 mode(vi | emacs)
term
application
的不同來做不同的特定
比如以下的設定可以讓bash 可以藉由C-x q來將前一個word用括號包起來
$if Bash
# Quote the current or previous word
"\C-xq": "\eb\"\ef\""
$endif
其中 \eb \ef 都是bash 預設的功能
向是\eb是往後跳一個word -->即是alt-b

基本上readline是蠻好用的功能，希望這篇文章能對你有幫助

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.
-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.
-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.
-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.
The return value is 0 unless an unrecognized option is given or an error occurred.
