To display line numbers in vim, you can use the :set number command.
To enable line numbering, open vim and type the following command:
:set number
This will enable line numbering and display the line numbers to the left of the text in the vim editor.
To disable line numbering, use the :set nonumber command:
:set nonumber
This will disable line numbering and hide the line numbers in the vim editor.
Note that the :set number and :set nonumber commands are toggle commands, which means that they will switch the line numbering on or off depending on its current state. If line numbering is currently enabled, the :set nonumber command will disable it, and if line numbering is currently disabled, the :set number command will enable it.
