[PLUG] Suppressing shell script output to screen

[brooks at netgate.net]

Any output from a script run by cron will be emailed to the user running 
the cron script unless you (as is typical) redirect it using somthing 
like:

25 1 * * *      /bin/elastic-backup >> /dev/null 2>&1

Or to a log file using something like this:

25 1 * * *      /bin/elastic-backup >> /log/elastic-backup.log 2>&1
