This article demonstrates how to stop receiving e-mail notifications from cron jobs.
By default, when a cron job is run, cron sends e-mail notifications to the user account. To disable email notifications, put >/dev/null 2>&1 to the cron job command. This redirects all cron job output to the /dev/null device. The following cron job, for example, does not send e-mail notifications:
15 * * * Sun ${HOME}/bigtask.sh > /dev/null 2>&1
To resume receiving e-mail notifications from cron jobs, simply remove >/dev/null 2>&1 from the command.
