Bash Shell 快捷键的学习使用
原文地址： http://dbanotes.net/tech-memo/shell_shortcut.html
这篇 Bash Shell Shortcuts 的快捷键总结的非常好。值得学习。下面内容大多数是拷贝粘贴与总结.
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 ?
