What I would do is put all of the work into a shell script, and have cron call the shell script. Just off the top of my head, something like: #!/bin/sh if [ -s /path/to/file ] mail -s Here's_the_file [EMAIL PROTECTED] < /path/to/file rm -f /path/to/file touch /path/to/file fi Warning: This has not been tested. I'm sure there are better ways to do it. This is just a *very* rough example of generally how to go about such a thing. I'm sure there are better ways to do it. The rm and touch lines might be combinable into something like "echo "" > /path/to/file" but I'm not sure. I'm sure there are better ways to do it. -- Mike Werner KA8YSD | He that is slow to believe anything and | everything is of great understanding, '91 GS500E | for belief in one false principle is the Morgantown WV | beginning of all unwisdom.
