The script deletes folders older than 10 days and sends a list of folders by mail.
You can change the value of-mtime X as needed. Also, please replace your email address with ours.

Set executable permissions for delete-old-files.sh
# chmod +x /opt/script/delete-old-files.sh
Finally add a cronjob to automate this task. It runs every morning at 7:00.
# crontab -e 0 7 * * * /bin/bash /opt/script/delete-old-folders.sh
