Output from nightly cronjobs is filling root's mailbox quickly, and sending everything else to /var/spool/mqueue. These are just status messages (stdout) from the cronjobs which we don't really need mailed to root. Is there anyway to suppress mailings?

Not sure when this sliped in.... Perhaps on my old Idris system. Or when I was last testing it on a Wyse50 terminal. -- T o m M i t c h e l l Looking for a place to hang my hat.

And pointless in a cron job line. Patrick knows what it does, he's wondering why. So am I.

Send your jobs to /dev/null like so: 30 0 * * * /path/to/program >> /dev/null Make sense?

The above addresses stdout as requested also consider stderr.. 2 1 * * * $HOME/bin/check-calendar > /dev/null 2>&1 < /dev/null & In general a unix program should be 'silent' unless there is an error. If cronjobs are filling the mailbox too quickly then look at the jobs to see why they are generating so much traffic. Also since this is root and most users 'never' login as root, ;-) also look at /etc/aliases. It is possible to send mail for root to a person. That person can sort, filter, read and dispose of the traffic as needed. Look near the lines: # Person who should get root's mail #root: marc Don't forget to run newaliases. -- T o m M i t c h e l l Looking for a place to hang mfors hat.

Send your jobs to /dev/null like so: 30 0 * * * /path/to/program >> /dev/null Make sense? Max Pyziur pyz(a)brama.com

Yes. 'man 5 crontab' - Set MAILTO="" in your crontab, and you will suppress mails. HTH /Anders
