lineinfile - Ensure a particular line is in a file

This module will search a file for a line, and ensure that it is present or absent.

This is primarily useful when you want to change a single line in a file only. For other cases, see the copy or template modules.

information so you can get the original file back if you somehow clobbered it incorrectly.
