vi command list

Three operating modes of Vi

Normal mode, also known as command mode

Insert mode

Command line (cmdline) mode

After entering Vi, the first thing you enter is the normal mode, and Vi waits Edit command input, that is, the letters entered at this time will be interpreted as commands.
In normal mode, enter the insert command i, append command a, open command o, etc. to enter insert mode. Any characters entered by the user in insert mode are saved as file content by Vi and displayed on the screen. During text entry, press the Esc key to return to normal mode.
In normal mode, use: to execute Ex commands, use ? and / to search, and use ! to call Shell commands. After the last line of commands is executed, Vi automatically returns to normal mode.
