In the command mode, you can issue commands and navigate the text. In the insert mode, you can insert and edit text.

Starting Vi Command

To start Vi, you need to open a terminal window and type "vi" followed by the name of the file you want to edit. If the file does not exist, Vi will create a new file with that name. Once Vi is open, you will see the command prompt at the bottom of the screen.
