No output from periodic

What you are seeing is an error condition...
You should be able to put a redirect into crontab...

Here's an example of one of my entries...
It runs every 5 minutes, the dyndnss.pl script and sends
output to /tmp/dyndnss.out AND any error messages (that's the 2>)
to /tmp/dyndnss.err

This works for me and I don't see any error messages.
In the actual script, if something goes wrong, I have it email me.
So I still get notified if the script fails, but I don't get any warnings
from CRON.

Hope that works.

Peter

I worry about my child and the Internet all the time, even though she's
too young to have logged on yet. Here's what I worry about. I worry
that 10 or 15 years from now, she will come to me and say "Daddy, where
were you when they took freedom of the press away from the Internet?"

Unix IS user friendly... It's just selective about who its friends are.

System Administration - It's a dirty job, but somebody said I had to do it.

If you receive something that says 'Send this to everyone you know,
pretend you don't know me.
