No output from periodic
I have a periodic that runs every 15 minutes. I have 5 scripts in the directory that it processes. Most of the time, the 5 scripts don't have to do anything, and thus don't have any output. When that happens, periodic outputs 'No output from the 5 files processed'. Is there a way to make periodic not output anything so that I don't get an email from cron every 15 minutes?

Re: No output from periodic
Yeah, I tried that... Now I just get a blank email from cron. :) Anyone know how to make cron not send an email when there's no output?

Re: 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.

Re: No output from periodic
I really appreciate all the comments, but this isn't quite what I'm after. I _want_ cron to email me when there _is_ output. But I _don't want_ an email when there _isn't_ output. Anyone know how to accomplish this?
