Bash Shell 快捷键的学习使用

CTRL 键相关的快捷键:

Ctrl + a - Jump to the start of the line

Ctrl + b - Move back a char

Ctrl + c - Terminate the command? //用的最多了吧?

Ctrl + d - Delete from under the cursor

Ctrl + e - Jump to the end of the line

Ctrl + f - Move forward a char

Ctrl + k - Delete to EOL

Ctrl + l - Clear the screen? //清屏，类似 clear 命令

Ctrl + r - Search the history backwards? //查找历史命令

Ctrl + R - Search the history backwards with multi occurrence

Ctrl + u - Delete backward from cursor //
密码输入错误的时候比较有用

Ctrl + xx - Move between EOL and current cursor position

Ctrl + x @ - Show possible hostname completions

Ctrl + z - Suspend/ Stop the command

补充:

Ctrl + h - 删除当前字符

Ctrl + w - 删除最后输入的单词 ALT
键相关的快捷键:

平时很少用。有些和远程登陆工具冲突。

Alt + < - Move to the first line in the
history

Alt + > - Move to the last line in the history

Alt + ? - Show current completion list

Alt + * - Insert all possible completions

Alt + / - Attempt to complete filename

Alt + . - Yank last argument to previous command

Alt + b - Move backward

Alt + c - Capitalize the word

Alt + d - Delete word

Alt + f - Move forward

Alt + l - Make word lowercase

Alt + n - Search the history forwards non-incremental

Alt + p - Search the history backwards non-incremental

Alt + r - Recall command

Alt + t - Move words around

Alt + u - Make word uppercase

Alt + back-space - Delete backward from cursor // SecureCRT
如果没有配置好，这个就很管用了。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

补充:

Esc + T - 交换光标前面的两个单词很多来自GNU 的
readline 库。另外一份总结也很好

记忆是所有技术人员的敌人。一次要把所有的都记住是不可能的。针对自己的使用习惯，对少数快捷键反复使用，短期内就会有效果。

你还知道那些好用的快捷键 ? 补充一下 ?
