After reading some of the responses I still thought it odd that cron would not run the script as nobody. So I setup two scripts to dump the env vars into a file, one script runs from /etc/crontab and one from nobody's crontab. Both are functioning perfectly. I have told the developer to re investigate his script and his directory perms. I looks like a case of PEBKAC to me. Thanks for the responses.

Thanks, DAve I've done this two different ways: One is to use sudo and have your script su - to nobody. You will need to test your script first before trying it through cron. Create a cronjob for nobody using: crontab -e -u nobody Hope this helps. -Derek -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Running cron jobs as nobody
Good morning all, We have a cronjob we need to run as nobody from /etc/crontab and it seems to be not working. The job runs, but not as user nobody. I noticed two things, 1) the job to update the locate DB runs as nobody, because the script uses su to become nobody. echo /usr/libexec/locate.updatedb | nice -5 su -fm nobody || rc=3 2) nobody, as expected, has no shell or home dir in /etc/password.

Re: Running cron jobs as nobody
You can use ``su -c '/path/to/command' username'' to run scripts as users other than root. Another way is to use ``crontab -u username''. man crontab for details.

Bill I am being told the developer tried a user crontab without success. I've not suggested they try su yet though I dropped hints. Still seems odd that setting the user to nobody in /etc/crontab did not work.
