Chris, The reply was deserved :) Just another question before I go too far with this... The files I am parsing (just needing 2 tabbed fields out of them) are approximately 20,000 - 25,000 lines long a piece. Each of these files will be globbed into one file, but that is something completely different. I guess my question is, would I be better off calling exec(cut) with files of this size for ease of use? Guess I should have mentioned this in my previous email.
