If you use a lot of cron jobs like I do, you tend to have some that you would like automatically sent over, and some you want to just let run without ever sending you an email and clogging your inbox. This line can be added to the end of your cron job command to stop the command from sending an email out and off to you:

>/dev/null 2>&1

Here would be a quick example for you:

php /home/my_directory_folder/public_html/support/cron/silly-job.php >/dev/null 2>&1

I know that this works for all cPanel hosts - if you have any better methods feel free to post them below.
