vi usage reference

Submit to reddit

Recently I had to do some work on a Solaris Server. This meant two things: finding a new appreciation for the user friendliness of the linux console and second it meant that I had to use the barebones vi. You know, the one where the arrows and backspace won’t work. Smart. So here’s a little list compiled with the more important functions

First I had to

export TERM=xterm

before vi worked correctly.

Create new file or Open existing file in vi
vi without any file name will open a new file where you can enter and edit text and when coming out you will be asked to enter a file name where to save the text. vi with a file name as argument will open that file for editing if the file already exists it opens it otherwise it creates a new one.

Modes

vi operates in following two modes :
Command Mode : After a file is opened it is opened in command mode ,that is , input from the keyboard will be treated as vi commands

– Insert Mode: To enter the text you have to put vi in insert by pressing ‘i’ or ‘a’ after which you can write the text and you will see it on the screen. To switch between these modes press Esc

Saving & Exiting vi editor
You can exit vi in different ways :

  • Quit without saving : If you don’t want to save the work :q will take you out without saving your editing in vi.
  • Write & quit : . Simple :w saves the current file but don’t exit. For save and quit :wq is used in vi.
  • Forced Quite : An ! after exit commands ( :q! , :wq! ) forces quit from vi after ignoring editing (for :q!) or writing (for :wq!) all the change
