Can't get udev rule to work on Ubuntu or Fedora
I can't get my udev rule to fire when I plug in a usb stick.
I've tried many different rules, but the ones I've settled on here are in  in the screenshots.
Also I tried with my fedora install usb, an RTL-SDR thing, and a freshly formatted USB stick with one ext4 partition.
 - plugged in the usb stick and grep for SUBSYSTEM in udevadm info
 - plugged in the usb stick and grep for DEVTYPE in udevadm info
 - show the usbstick is there in lsblk
 - cat out the script I plan to attach to my rule with RUN+=
 - the script is in the right spot, /opt/script.sh. It's executable and owner/group is root
 - cat out the rules. There are 2 different ones I tried
 - run lsblk again. See the usb stick has been unplugged
 - reload rules with udevadm control --reload
 - show the usb stick has been reinserted.
 - the script didnt work! It was supposed to create a file in /tmp
back to poking around . . .
Any tips appreciated!
