其他特定的键绑定:

输入 bind -P 可以查看所有的键盘绑定。这一系列我觉得更为实用。

Here “2T” means Press TAB twice
$ 2T – All available commands(common) //命令行补全，我认为是 Bash 最好用的一点
$ (string)2T – All available commands starting with (string)
$ /2T – Entire directory structure including Hidden one
$ ./2T – Only Sub Dirs inside including Hidden one
$ *2T – Only Sub Dirs inside without Hidden one
$ ~2T – All Present Users on system from “/etc/passwd” //第一次见到，很好用
$ $2T – All Sys variables //写Shell脚本的时候很实用
$ @2T – Entries from “/etc/hosts” //第一次见到
$ =2T – Output like ls or dir //好像还不如 ls 快捷
