Disable mail notification in crontab

When I use a crontab to schedule a smart script with embedded mail notification function, it’s annoying to have a notification sent by cron process (a stupid notification with no interesting information). I will explain you how to disable mail notification in crontab.

I – Disable mail notification in crontab

By default cron process always send mail notification, it’s possible to disable mail notification for one cron job. You just need to redirect the default stdout to /dev/null.

root@cron:~# crontab -e
30 * * * * /opt/ > /dev/null 2>&1

An another way exists, but its global, its apply to all schedules tasks. You disable mail notification, just define no mail address on the option MAILTO.

root@cron:~# crontab -e
