What is vi in linux

Vi is a text editor developed by Bill 喜悦 of the University of California, Berkeley.

There are many text editors, such as gedit, kwrite, OpenOffice in graphic mode, and vi and vim (an enhanced version of vi) in text mode. Vi and vim are our most commonly used editors in Linux. Vi or vim is the most basic text editing tool of Linux. Although vi or vim is not as simple as the mouse click operation of the graphical interface editor, the vi editor can never be compared with the graphical interface editor in the system management and server management character interface.

Note: vi is the most classic text editor in the unix/linux operating system, it can only edit characters, not typography of fonts and paragraphs; it can either create or edit files; it has no menu, only commands, and many commands.

Although vi operates very differently from other commonly used text editors such as gedit, it is still used frequently because it runs in a character interface and can be used in all unix/linux environments.

Three Command modes of vi

Command (command) mode for entering commands

Insert (insert) mode for inserting text

Visual (visual) mode for visual highlighting and text selection

1. Command mode:

Command mode is the working mode that is entered after starting vi, and can be converted to text editing mode and last line mode. In command mode, any characters entered from the keyboard are interpreted as editing commands and are not displayed on the screen. If the character entered is a valid vi command, vi will complete the corresponding action; otherwise, vi will ring a warning.

two。 Text editing mode:

Text editing mode is used for character editing. Enter I (insert command), a (additional command) and other commands in command mode and enter text editing mode. At this time, any characters entered are displayed on the screen as file content by vi. Press ESC to return to command mode from text editing mode.

3. Last line mode:

In command mode, press the ":" key to enter the last line mode, and vi will display the ":" symbol year at the bottom of the screen as a prompt for the last line mode, waiting for the user to enter the relevant command. After the command is executed, vi automatically returns to command mode.
