I have two lists of filenames, and I need to delete every entry from the

seems awfully slow ... can anyone tell me if there is a way to do it in ksh
that runs faster than this does?:
untested:
perl -nle 'BEGIN{ @x{`cat secondlist.txt`} = () } exists $x{$_} or print' <
firstlist.txt >filteredlist.txt
mv filteredlist.txt firstlist.txt

Sometimes I imply things, or include important information in pictures.
Without a request for clarification, I will assume I was clear, which can
cause later problems when I wasn't. So please ask me to clarify anything
that seems ambiguous. Doing so is not rude. Thank you.
