I'm using grep, but I don't know what version.  It's a virtual linux machine
that I access via a web browser for labs for class... I could do a local
install, but it wouldn't have the files we're supposed to work with.

That's what I would have thought, but I found that \. didn't return any matches,
whereas [.] did.  Probably a quirk of the version I was using.

Thanks, I turned in my lab report with what I thought should work, and noting
that it didn't.  That was the only problem with it, so I doubt I'll lose too
many points.
