Linux common commands

Vim

VIM (text editor for Unix and Unix-like systems)

Vim is a well-known powerful, highly customizable text editor similar to Vi, which improves and adds many features to Vi.

"Focus."

In Vim, there are three modes: command mode, input mode and last line mode.

Press ESC to enter command mode

Enter Shift + ; to enter Last Line Mode

Enter insert commands such as (i,a,o) to enter insert mode

Note that the premise of entering the last line mode must be command mode, that is, after entering the command, you must first return to command mode.

:wq last line mode, wq save exit

:q End line mode, q directly exit

:q! Last row pattern, q! Forced exit, do not save

i Insert from the front of the cursor

I Insert at the beginning of the current line

a Start typing from behind the cursor.

A Insert at the end of the current line

o Add a line below the cursor line and enter input mode

After entering the input mode, the word--INSERT-appears on the last line
