Thanks everyone for the ideas.

I knew find could do modification times and the like but always found it 
a a bit of a pain. In fact, I think the find I used in the past may not 
have had cmin The find command avove is peachy for what I want (minus 
the !).

I liked the fuser idea but alas you need to be root. Didn't seem to have 
lsof.

Thanks again all.
