vi Editor Top Commands for Ubuntu OS

I have given VI editor commands to use in Ubuntu operating system. You can practice using them for your benefit and you can complete your work quickly.

To begin changing or adding to text with vi, you can enter Insert or Replace modes, as shown in the following list. When you enter Insert or Replace mode, the characters you type will appear in the text document (as opposed to being interpreted as commands).

This is the first command to enter into editor mode. Once you enter into editor mode, you need to enter other commands to complete your editing work.

Press the Esc key to exit to Normal mode after you are done inserting or replacing text.
