in reply to Regex variables with delimiters

I would suggest that you not use perl. grep has built in switches to handle exactly this case.

 grep -v -f file_of_filters logfile > filtered_logfile

    Except, of course, in the very common case that this code is part of a larger script or chain of processing, in which case calling grep as an external program has more disadvantages than just doing everything in Perl.
