Using grep with hyphens

[woodson2]

This is on a RHEL 6 box with bash 4.1.2

I'm trying to to use grep to only find those lines containing matches that form whole words.

The -w option works fantastic unless of course that word has a hyphen.

The problem is I will get a hit on "test-group" which is a good thing, but I will also get a hist on "test" which is bad because the group test doesn't exist. It appears that once grep hits a hyphen it treats the preceding text as a whole word.

Any ideas would be greatly appreciated.

Next time no groups with hyphens..

Thanks

This seems to be an odd place to be asking about that, then...
