Nice... or slightly more compact:

   	groups $users | cut -d: -f2-|tr " " "\012" |sort | uniq -c | sort -nr

I haven't had coffee yet this morning, so I'm not ready to think in 'awk', but
I'm sure the the process could be reduced to:

	groups $users | awk '{some hideous expression}'

It's like playing "Name That Tune" with command pipelines...can a process be
done with fewer fork()s?
