Basically, vi can be divided into three states: command mode (command mode), insert mode (Insert mode) and bottom line mode (last line mode). The functions of each mode are as follows:

1. Command line mode command mode)

Control the movement of the screen cursor, the deletion of characters, words or lines, move and copy a section and enter the Insert mode, or to the last line mode.

2. Insert mode (Insert mode)

Text input can only be done under Insert mode, and press the "ESC" key to return to command line mode.

3. Bottom line mode (last line mode)

To save or exit vi, you can also set the editing environment, such as finding strings, listing line numbers, etc. Wait.

Some basic operations of vi

1. Enter vi

After the system prompts for the symbol vi and the file name, go to the vi full screen editing screen:

For example:

$vi myfile

2. Switch to insert mode (Insert mode) to edit the file

Press the letter "I" in "command line mode (command mode)" to enter "insert mode (Insert mode)" and you can start typing text.

You are currently in "Insert mode mode", so you can only type text all the time. If you find that you have typed the wrong word and want to use the cursor key to move back and delete the word, press the "ESC" key to go to "command line mode (command mode)" and then delete the text.

4. Exit vi and save files

Under Command Line Mode (command mode), click the: colon key to enter Last line mode, for example:

W filename (enter "w filename" to save the article with the specified file name filename)
