Common Vim commands

Vimm (vimsual) is a full-screen editor used in Linux/Unix OS.

Vimm is divided into two states: command status and edit status. In command status, the entered character system performs command processing. For example, Q indicates that the system exits, the editing status is used to edit text materials. When you enter vim, it first enters the command status. In the command status, press "I" (insert) or "A" (ADD) to enter the editing status. In the editing status, Press ESC to enter the command status.

In the command status, there are some common commands:

New:

A. Add text after the cursor

A. Add text from the end of the row where the cursor is located

Insert:

I insert text from front of the cursor

I insert text from the beginning of the row where the cursor is located

Delete and modify:

X Delete characters at the cursor

Dd deletes the entire row where the cursor is located.

3DD Delete the row where the cursor is located and the following two rows

D. Delete the text from the cursor to the end of the line. It is commonly used to delete the comment Statement (d $)
