How to display or hide line numbers in vi or vim text editor

This post assumes you are a vim user and are aware of basic usage. Like for example when you need to save and quit data in vim you-
  • press escape followed by :wq
or if you want to exit without saving
  • :q!
 vi support a lot of commands to use and  options to be set by using colon (:)

To show line numbers in vi simple type below are pressing escape -
  • :set number OR
  • :set nu
 To hide it you can type -
  • :set nu! OR
  • set nonumber





This you need to do every time you launch into vi editor. To make it default edit your file at location ~/.vimrc and append following line at the end -

  • set number

This is also fairly simple. Once you have launched vim you can simply move to any line number using following command -

  • vi +linenumber filename
Eg.
  •  vi +6 test.txt
This should open your file and move to the linenumber you have provided.
