bind 命令补充说明:


bind 命令用于显示和设置命令行的键盘序列绑定功能。通过这一命令,可以提高命令行中操作效率。您可以利用 bind 命令了解有哪些按键组合与其功能,也可以自行指定要用哪些按键组合。

bind 命令语法:


bind [-m keymap] [-lpsvPSV]
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

bind 命令选项:


-d:显示按键配置的内容;
-f<按键配置文件>:载入指定的按键配置文件;
-l:列出所有的功能;
-m<按键配置>:指定按键配置;
-q<功能>:显示指定功能的按键;
-v:列出目前的按键配置与其功能。

bind 命令实例:


bind -x '"\C-l":ls -l'    #直接按 CTRL+L 就列出目录

其中 keyseq 可以使用 showkey -a 命令来获取:

[root@localhost ~]
$ showkey -a

Press any keys - Ctrl-D will terminate this program
