Yeah, you'd want fgrep so that it doesn't interpret anything as a
meta character, but that's also going to encounter problems if there's
any NULs in your search string.

But yeah this is something that'd be fairly easy in perl.  I think I
even had a golf'd obfuscated one lying around somewhere, but I can't
find it at the moment.  You can find something that might be helpful
at perlmonks here:
