VI is the abbreviation of "Visual interface", its status on Linux as if the edit program on DOS. It can perform many text operations, such as output, delete, find, replace, block operations, and so on, and users can customize them according to their own needs, which is not available in other editing programs.
VI is not a typesetting program, it is not like word or WPS can be the font, format, paragraph and other properties of the orchestration, it is just a text editing program.
VI There are no menus, only commands, and commands are numerous. VI has three basic modes of operation: command line mode, text input mode, and last line mode.
Command-line mode (commands mode/general mode)
At any time, no matter what mode the user is in, just press the key to make VI into the command line mode; We enter the Launch VI command under the shell environment (prompt $), and it is in that mode when you enter the editor.
In this mode, users can enter a variety of legal VI commands for managing their own documents. Any character entered from the keyboard is interpreted as an edit command, and if the input character is a valid VI command, VI completes the corresponding action after accepting the user command. Note, however, that the commands you enter are not displayed on the screen. If the input character is not a legal command of VI, VI will ring the alarm.
Text input mode (input mode/edit mode)
Enter the input command in command mode i, attach command A, open command O, modify command C, replace command R or Replace command s can enter the text input mode. In this mode, any characters entered by the user are saved by VI as the contents of the file and displayed on the screen. In the process of text input, if you want to return to the command mode, press the button.
Final line mode (last lines mode/command mode)
The last line mode is also known as ex escape mode.
The functions of the VI and ex editors are the same, the main difference being the user interface. In VI, commands are usually a single key, such as I, A, O, etc., whereas in ex, the command is the body line that ends with a hit return. VI has a dedicated "escape" command to access many of the line-oriented ex commands. In command mode, the user presses the ":" Key to enter the last row mode, at which time VI displays a ":" As a prompt in the final row of the display window (usually the last line of the screen), waiting for the user to enter a command. Most file management commands are executed in this mode (such as writing the contents of the edit buffer to a file medium). After the last command is executed, VI automatically returns to the command mode.
