Regexp style globs for what you're looking for would be either .* (greedy) or .+ (non-greedy), with it being most likely the latter case.

Ah I understand the difference now. Thanks.

I think going for the simpler glob option might be best. In my earlier
example a regex would have problems with all the periods, would it
not? Also if I want to match anything I would always forget to write
.* instead of just *

I was just having a quick look at how to implement this, would it be
best to use the fnmatch function? Having a quick browse of the FreeBSD
source I found csh_match in /usr.sbin/pkg_install/lib/match.c:L456
which seems to do something similar to what we want.

BTW Feel free to implement this, I was going to have a go but I doubt
I'd actually get around to it :(
