The VI Text Editor

Command Mode

  • vi has no GUI so all operations are

performed from keyboard.

  • Commands are typed from keyboard, for

example:

– dw – deletes the word at the cursor – dl – deletes the current line – :wq – save file and quit.

  • You cannot type text while in Command

Mode.

Text Entry Mode

  • Whatever you type while in Text Entry Mode

appears in your document.

  • To switch to text input mode you use:

– i - will switch to text mode and allow typing at cursor. – a – will switch to text mode and allow typing at character immediately after cursor.

  • You can use arrows keys to navigate while in

text entry mode.

  • The ‘Esc’ key will return you to Command Mode.
