By default, cron sends the reports of scheduled cron jobs to the mail of the user who scheduled the job.

You can redirect this by changing the mail variable’s value, as shown in the next example.

# crontab -l
MAIL=bob@admin.com
0 2 * * * /script/backup.sh

After the cron job backup.sh is executed, cron will send the reports to the mail address bob@admin.com.
