Why do I keep getting an email each time my Cron job runs?
The email is crontab's way of notifing you that it has completed (or not) the job you requested it to run. After everything is running smoothly, you may want to disable this feature, or redirect the output to a log file instaed of an email.

If you wish to diasble the email (and not output to a log file) then, at the end of each of the cron job lines you wish to not be notified on, place the command:

>/dev/null 2>&1

This essential writes the email out to nowhere (a trash bin of sorts), and thus solves the problem. Your final cron job line will look like this:

45 4 * * * rm /home/{username}/temp/* >/dev/null 2>&1

If you wish to diasble the email (and output to a log file) then, at the end of each of the cron job lines you wish to not be notified on, place the command:

> {logfile path and name}
or
>> {logfile path and name}

Special Note: One > means replace the current log with a new one, while (two) >> means append the current output to the end of the current log.

This essential writes the email out to nowhere (a trash bin of sorts), and thus solves the problem. Your final cron job line will look like this:

45 4 * * * rm /home/{username}/temp/* > /home/{username}/cronlogs/clear_temp_dir.txt >/dev/null 2>&1

crontab -v
