AppleScript executes itself again after a reboot it initiated. How to avoid that?

I have a shell script that is run by an AppleScript app. That shell script restarts the machine at some point with shutdown -r now.

How can I avoid having the AppleScript application automatically launch itself again after the reboot?

• The app is not included in the startup items


• The app is launched again just like any other open app when the shell script restarts OS X

The sequence is this:

1. I double click on the AppleScript app


2. AppleScript launches a shell script in Terminal


3. The shell script, at some point, reboots the system


4. The AppleScript app starts again after the reboot
