Disable crontab mail
By default, crontab on, for example, Debian, will mail any output of a job in your crontab to that user. How would one go about disabling this functionality?
Solution 1:
There are two main ways of doing this, as I discovered.
Either you set the MAILTO-variable to nothing at the start of the file:
MAILTO=""
or you redirect each cronjobs output to /dev/null:
<command> > /dev/null
The second having the advantage that output on stderr should still be mailed to you.
Solution 2:
To prevent output of both stdout and stderr use the following syntax:
<command> > /dev/null 2>&1
