Arrgghh. You're now making me /think/ about the script, rather than it
being a throwaway suggestion(!) Upon further investigation, the atime
for a symbolic link is (inevitably) updated when it's deferenced, so
you need to skip those, too.
The find statement thus becomes
find $(readlink -f "$F") -atime -180
On my laptop it's tricky for me to test this as I mount everything
noatime. On a couple of servers I've got, though, the results feel
If you're finding that everything is "in use" then at this stage it's
probable that you've made a filesystem backup with tar or cpio, which
obviously reads every single file, unfortunately making atime useless.
