Sorry you've lost me. Why would you want this?
If you wanted to compare hashes wouldn't it be better
to pipe to uniq with something like: md5sum * | uniq --group -w32

Also this doesn't strictly need to be within the *sum utils,
so if not of general use, it might be best done as a separate util
(which could also sort similarly perhaps)?
