In this article, we explain to you Linux vi commands and Implement them.

#### Theory and Output:

 * The vi editor (short for a visual editor) is text editor which is available on
   almost all [Unix/Linux](https://technotaught.com/study-of-general-commands-of-ubuntu/)
   systems
 * vi has no menus but instead uses combinations of keystrokes in order to accomplish
   commands.
 * you can use vi editors to edit(add, change, and delete text) an existing file
   or to create a new file from scratch. You can also use this editor to just read
   a text file

The [UNIX](https://technotaught.com/basic-networking-command-in-linux-unix/) vi-
editor is a full-screen editor and has two modes of operation:

 * **Command mode**: This mode enables you to perform administrative tasks such 
   as saving files, executing commands, moving the cursor, cutting and pasting lines
   or words, and searching and replacing. In this mode, whatever you type is interpreted
   as a command
 * I**nsert mode**: This mode enables you to insert text into the file. Everything
   that’s typed in this mode is interpreted as input and finally, it is put in the
   file.
 * By default vi is in [c](https://technotaught.com/study-of-general-commands-of-ubuntu/)**
   [ommand mode.](https://technotaught.com/study-of-general-commands-of-ubuntu/)**
