search for discrepencies in file contents 2

[MISMCSA]

This is the scenario.

I have two text files with lists of user IDs. One file is a list of random user IDs and the other is a masterlist containing all user IDs that are part of a group.

What I want to do is write a script that cycles through every ID that is in list of random users and searches for that ID within the master list.

the object of this script is so I know which users, in the random list, are not part of the master list.

Thanks for your help!
