This is backwards. You needs to redirect stderr before redirecting stdout:
foo 2>&1 > /dev/null
Or, the MAILTO line in the crontab can be tweaked (it works in a top-down
fashion):
# Mail results to [EMAIL PROTECTED] until otherwise specified.
[EMAIL PROTECTED]
* * * * * foo
* * * * * bar
#
# No output on following items.
MAILTO=""
* * * * * baz
The foo and bar lines will have output mailed, but baz won't. I still
don't think it's a good idea to close output, whether using MAILTO or
/dev/null, but those are the options.
A much better technique would be to *minimize* output so that you only get
an email when a cron job fails. A simple way to do this would be:
* * * * * foo 2>&1 > /dev/null || echo "Foo failed. Fix me."
Otherwise, you might never know there's been a problem.
