RobinHood,
Did you get a chance to peruse my recent post that is asking a similar question?
Script for adding in a new ePolicy Orchestrator server
Essentially, this looks at an INI file for a string using READLINE and if it does not exist, it makes changes using WRITELINE, closes the file and then uses WRITEPROFILESTRING to make additional changes.
This should get you pointed in the right direction.
HTH,
Kent
