Any app is going to have a binary, no? Also, you might try 60 or 90 or even more days old. I tested in /usr/bin, and found whoami had not been accessed in last 30 days. I ran whoami, then reran the 'find...' command again and whoami was no longer on the list. > >There's an obvious problem - it hits up every file, regardless.

Can someone point out the staggering (yet quite >invisible to me) stupidity I'm undoubtedly committing? I couldn't get xargs dpkg -S to return anything, either. Look at the output of 'find', it includes the directory. I would guess that the filename needs to be extracted before it's given to xargs, to pass to dpkg. -- gt It is interesting to note that as one evil empire (generic) fell, another Evil Empire (tm) began its nefarious rise. -- me Coincidence?
