How to avoid mail from at scheduled job?

How do avoid getting a mail with the output from scheduled tasks?

I have this script that runs at different intervals. To do this it reschedules itself with the at command, like this:

Code:

echo $COMMAND | at now + <interval>

When that executes, it writes "job xxx at yyyy-mm-dd hh:mm" on stdout (i guess?), and this output is then put in a mail to me. I don't need to get this output, so how do I avoid getting these mails?

Thanks.

I'm sorry if this question has been asked before, but I wasn't able to get any meaningful search results.

Just redirect the output to /dev/null, youll never hear from it again... (;

Code:

echo "$COMMAND > /dev/null" | at now + <interval>

This will only redirect standard output, so any errors weill still get mailed to you. If you redirect also standard error it would look like this:

Code:

echo "$COMMAND > /dev/null 2>&1" | at now + <interval>

The quotes arew important, otherwise the echo would go to devnull instead of the output.. (;

Thanks, you led me onto the right track...
Although your redirection-suggestions doesn't actually work as I intended... The message I kept getting was the output from the at command, so to avoid the mails, the command must be like this:

Code:

echo "$COMMAND" | at now + <interval>  > /dev/null 2>&1

Thanks
