Re: Which grep match?

grep -o

I read about that previously on the man page but for some reason
discounted what it was suppose to do, thinking it was not my
intention.  But it appears to do exactly what I'm interested in having
done (at least for grep and fgrep queries, not egrep, but that's fine
for now).

Thanks,
Scott
