Removing old directories from FreePBX?

Question

Asterisk

Good afternoon everyone, I ask for your help. For himself sooo little familiar with * nix.
There are several scripts on the Freepbx server, in short:
The first script cleans the database of old CDR records
The second one cleans the *.wav files themselves in the /var/spool/asterisk/monitor/%year%/%month%/day% folders
Now to the point , what to add to the script so
that it also cleans the empty folders themselves older than 91 days? records:

find /var/spool/asterisk/monitor/ -name "*.*" -type f -mtime +91 -print -delete >> /etc/asterisk/scripts/delrecord.log

I will be glad for any help.

Answer 1

find /var/spool/asterisk/monitor/ -type d -empty -exec rmdir {} \; # Удаляем пустые диры

This is how you clean up empty directories.
