There may even be a knob to tweak somewhere for this. That's what I was hoping for - tweaking the source is not a very clean way to solve my problem. In case you're interested (or anyone else listening), it seems that 'chown' likes to live in /usr/sbin - i.e., A place not in the default path. As it happens, a root cron task is trying to run a script that uses 'chown' and is thus failing. I can change the PATH just for root's crontab and solve the problem. I was just curious if there was a way to more broadly modify the defaults used by cron. Thanks again, for your time in this matter ... -- ---------------------------------------------------------------------------- Tim Daneliuk tundra@tundraware.com PGP Key: http://www.tundraware.com/PGP/
