Top Forums Shell Programming and Scripting Sed/grep: check if line exists, if not add line? Post 303013263 by MadeInGermany on Monday 19th of February 2018 02:52:37 AM

What line do you search for,
searchstring or addstring or both?
What to do in which case?
Your function looks only for searchstring and adds addstring behind it.
But the subject and text says a string should be added if something does NOT exist.
