Comment and uncomment the multiple lines in vi editor linux

Suppose we need to comment the lines from 6th line to 20th line in vi text editor using below syntax in vieditor.

from 6 line to 20line

type ESC in vi editor

:6,20s/^/#/

  

Here ^ indicates starting of the line. So We replaced starting of line with '#' means comment the line.

from 6th line to 20th line

type ESC in vi editor

:6,20s/^#//

From above one line started with # will be removed, line uncommented
