Cron / Crontab – disable e-mail notifications

There are 2 ways to prevent cron to send out e-mail notifications after jobs are run:

1. Ensure there are no output from the script(s) being run by sending the output to /dev/null
   Simply append one of the following directives to the end of your script.

   >/dev/null 2>&1.

   OR

   &> /dev/null

   Your crontab would now look something like:

   0 1 5 10 * /path/to/script.sh >/dev/null 2>&1

   OR

   0 1 5 10 * /path/to/script.sh &> /dev/null

Update MAILTO variable

2. As the e-mail notification is sent to the local account by default, it is possible to overwrite that by setting the MAILTO=”" variable within the crontab file. Simply enter the following at the start of your crontab file:
   

   MAILTO=”"

   so that it looks something like:

   MAILTO=”"
   0 1 5 10 * /path/to/script.sh &> /dev/null
