An Introduction to vi

The program vi is used to make text edits to files in this tutorial; it is the Linux version of Microsoft Notepad. While not the only option, it is probably the most popular, and it is natively available in every distro of Linux tested.

The two modes vi operates in are Edit mode and Command mode. Edit mode lets you make changes to the text in the file. Command mode lets you enter commands, such as save, quite, delete, or go to line. By default, vi opens in Command mode. Below is a table of commands that will make operating vi a lot easier.

Action	Command
Open file to edit in vi	sudo vi <file name>
Open file in vi as read-only	vi <file name>
Save changes and quit	:wq
Quit without saving changes	:q!
Delete text under cursor	del key
Delete entire row	dd
Insert text before character under cursor	i
Insert text after character under cursor	A
Insert text on a new line after current line	o
Insert text on a new line before current line	O
Go to specific line	:<line number>
