Try using this only in /bin, /usr/bin, and /usr/local/bin directories,
and set depth to only the one level. 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.

If you run only in a bin/ directory, the 'x' bits are set, no need to

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.

Coincidence? I think not.
