[ILUG] grep ??

[O'Leary Patrick]

Hi folks,
         I have been given a very large logfile & a list of about
40 names. my job is to find every  entry in the log which matches each
name in the list of names. i was thinking of simply doing something
like "cat xyz.log | grep each name > output.txt" but the lazy bugger
in me does not feel like doing that 40 times. i've trawled the web but
can't come up with a way of giving grep the list of names as a single
file. Any suggestions or help would be gratefully appreciated

Pat.
