    Mailing the crontab output

    By default cron saves the output in the user's mailbox (root in this case) on the local system. But you can also configure crontab to forward all output to a real email address by starting your crontab with the following line:
    MAILTO="yourname@yourdomain.com"

    Mailing the crontab output of just one cronjob

    If you'd rather receive only one cronjob's output in your mail, make sure this package is installed:
    aptitude install mailx
    And change the cronjob like this:
    */10 * * * * /bin/execute/this/script.sh 2>&1 | mail -s "Cronjob ouput" yourname@yourdomain.com

    Trashing the crontab output

    Now that's easy:
    */10 * * * * /bin/execute/this/script.sh 2>&1 > /dev/null
    Just pipe all the output to the null device, also known as the black hole. On Unix-like operating systems, /dev/null is a special file that discards all data written to it.
