I tried using fdupes like this but I wasn't able to see anything.=20 Probably because it took so long to run and never completed? It does=20 actually feature a -d flag too which does delete stuff but from my=20 testing this deletes all duplicates and doesn't allow you to choose the=20 directory to delete the duplicate files from, unless I failed to=20 understand the man page. At present the Perl script from Paul in it's last iteration solved my=20 problem and was pretty fast at the same time. Of course at first I tested it on my test dirs in /tmp, then I took zfs=20 snapshots on the actual working dirs and finally ran the script. It=20 worked flawlessly. Regards, Kaya
