That should do it.
Like I said, about 10 seconds.
Thanks!
Carl.

How about this:
for line in `cat EntryFile`; do grep $line LogFile; done
To make it a little more user-friendly, add an echo so you know what
you're looking at:
for line in `cat EntryFile`; do
echo "Searching for $line"
grep $line LogFile
done
Note that if EntryFile has spaces in the lines this won't work; $line
will be set to each *word* rather than each *line*.
HTH,
Jeff
