Summarize linux and unix commonly used shortcut keys, skilled use of these shortcut keys, efficiency is not only a little bit, I am deeply experienced. Who knows who uses it.

Ctrl+A: Switch to the beginning of the command line.

This is the same effect as Home. But Home is not available in some unix environments, so you can use this key combination.

Ctrl+E: Switch to the end of the command line.

This is the same effect as Home. But Home is not available in some unix environments, so you can use this key combination.

Ctrl+L: Clears the screen.

Ctrl+U: Clears the content before the clipping cursor.

Ctrl+K: Cuts the content after the clear cursor.

Ctrl+Y: Paste the character you just deleted.

This command is similar to Ctrl+Z Undo in office.

Ctrl+R: Find in History Command

This command is very practical, when history content is more, want to find a more complex command, directly use this shortcut key, enter keywords, shell will automatically find and call, very convenient.

Ctrl+C: Terminates the command.

Ctrl+D: Exit the current terminal.

Ctrl+Z: Go to background and suspend.

!!: Repeat the last command.

History shows all the numbered + historical commands you have executed. You can use it together! to carry out an order.

Ctrl+P: Display the previous command. The action is equivalent to an upward arrow.

Ctrl+N: Displays the next command. The effect is equivalent to a downward arrow.

!$: Displays the most recent command in the system.

An example of this command is that I first cat 1.txt content and then want to edit it with vim. The general practice is to display the last command with the up arrow, then move to the front of the command with home, delete cat, and type vim.

You can actually use vim!$ to replace it.
