[KLUG Members] method of grep list of .gz files?

[Scott Wood]

zcat is nothing but an uncompress piped out to stdout.  gz has similar
parameters (gzip -dc) and similarly for bzip2 (bzip2 -dc).  'd' for decompress,
'c' for cat to stdout.

For stuff like what you speak of, if it's a quick fix, you could build a simple
shell script with an for loop and an 'if' clause.  (I'm not in front of my *nix
box right now, but if you check the grep manpage, there's even a way to get it
to report a simple 'true'... -q or something like that, as well as a 'count' of
matches... -c ?)  If they are on seperate trees, check out 'find [path] -type f
-name \*.gz' to seed your for loop with filenames.

Of course, if it's more than just a dirty quick-shot, I would do it in perl
with the Gzip cpan libs.
