＃＃注：以下字母不分大小写

# Ctrl A - Go to the beginning of the line you are currently typing on

# Ctrl E - Go to the end of the line you are currently typing on

切到命令行开始｜结尾

# Ctrl xx - Move between EOL and current cursor position

光标在当前行的开头和结尾切换

# Ctrl L - Clears the Screen, similar to the clear command

清屏，类似于 clear 命令

---------------------------------------

# Ctrl U - Clears the line before the cursor position. If you are at the

end of the line, clears the entire line.

清除光标以前

# Ctrl K - Clear the line after the cursor

清除光标之后的所有内容。

---------------------------------------

# Ctrl H - Same as backspace

退格键 backspace

---------------------------------------

# Alt F - Move cursor forward one word on the current line

光标向前移动一个词的距离

# Alt B - Move cursor backward one word on the current line

光标向后移动一个词的距离

---------------------------------------

在图形界面下使用终端时会与Alt+F(打开file菜单)冲突，可以在 keyboard

Shortcuts选项中禁用file菜单项，即 (x)Disable all menu access keys(such

as Alt+f to open File menu)

这样就可以用shell自身的shortcuts了。

# Ctrl R - Let’s you search through previously used commands

从命令历史中找

# Ctrl C - Kill whatever you are running

终止命令

# Ctrl D - Exit the current shell

退出 shell

# Ctrl Z - Puts whatever you are running into a suspended background

process. fg restores it.

这个指你想中断一下当前执行的程序，但又不想杀死它，可以把它放到后台，想继续执行时，用fg可以唤醒它。
