cron job to delete Thumbs.db

Hi

I want to setup cron to run a job every day at 5am that deletes all of the Thumbs.db files on my unraid, the command that works on the command line in telnet is:

find /mnt/disk[1-9]*/ /boot -name "Thumbs.db" -depth -exec rm -r "{}" ';'>/dev/null 2>&1

Can someone tell me how I would add that to a cron job?

Thanks,

Dan
