udev question: using external programs to name device

Hi all, I'm stuck on this udev rule. I want to use a shell script to name a device.

KERNEL=="sr0", PROGRAM="/etc/cazzette %k", SYMLINK+="%c"

echo cazzette_$1

This should name my device as /dev/cazzette_sr0, correct? For some reason, it's not working. Can someone give me a tip why it's not?

What I want to do is actually much more complicated. I want to eventually do something like PROGRAM="/etc/cazzette %p" and run the devpath through a bunch of find/cut/awk/sed/etc.

I think I figured it out. I needed a shebang (#!/bin/sh) in /etc/cazzette. Didn't think it was that critical to cause it to fail.
