What are the commonly used commands in vi editor?

Commonly used commands in the vi editor are: 1. i, switch to input mode; 2. x, delete the character at the cursor position; 3. q, exit editing; 4. w, save the file; 5. a, insert content at the cursor position; 6. o, insert a new line after the cursor position.

Using vi/vim

vi is a full-screen editor that works in a character terminal environment, so the editing interface is relatively simple. It does not provide users with mouse operations and menu systems, but implements corresponding editing and operation functions through key commands. Three different working modes can be used in the vi editing interface. They are Command mode, Insert mode and Last line mode. Of course, the operations that can be performed on files in different modes are also different.

Command mode:

The user has just started vi/vim and entered the command mode.

In this state, keystrokes will be recognized by Vim as commands instead of entering characters. For example, if we press i at this time, we will not enter a character. i is treated as a command.

The following are some commonly used commands:

i Switch to input mode to enter characters.

x Delete the character at the current cursor location.

: Switch to bottom line command mode to enter commands on the bottom line.

If you want to edit text: Start Vim, enter command mode, press i to switch to input mode.

The command mode only has some of the most basic commands, so you still have to rely on the bottom line command mode to enter more commands.

Input mode:

Press i in command mode to enter input mode.

In the input mode, you can use the following keys:

character keys and Shift combination, enter the characters

ENTER, enter key, line feed

BACK SPACE, backspace key, delete the character before the cursor

DEL, delete key, delete the character after the cursor

direction key, move the cursor in the text

HOME/END, Move the cursor to the beginning/end of the line

Page Up/Page Down, page up/down

Insert, switch the cursor to input/replace mode, the cursor will become a vertical line/underline

ESC, exit the input mode and switch to the command mode

Last line mode:

Press: (English colon) in the command mode to enter the last line mode.

Last line mode allows you to enter single or multiple character commands. There are many available commands.

In the bottom line command mode, the basic commands are (the colon has been omitted):

q Exit the program

w Save the file

Press the ESC key You can exit last line mode at any time.
