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.
