how to suppress error messages

[Charles Li_2]

I has a cron that when run will generate an email message of the cron's output.
Is there a way to tell it not to generate the output?

Thanks

You can pipe the output to /dev/null

scriptname > /dev/null

You will get no output.

You may not be able to figure out when it fails.

A cronjob will generate an email if it is explicitly told to or if it exits with an error. If the mail statement is within the script itself, then you will need to modify the script and find for "sendmail|mailx|elm" etc., If not, then it may be directly fed into the cron entry itself in which you will need to redirect the output to /dev/null instead to the mail agent. Post your cron entry "crontab -l" and one should be able to figure it out.

Charles,
As SEP suggested, you can suppress the output of the scripts which are kicked of by cron by redirecting to /dev/null.
For stdout 1>/dev/null and for other error messages 2>/dev/null.
