Linux系统下Shell命令行快捷键实用技巧
2009-01-22 14:01
＃＃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


# 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。
