I have Lion and Snow Leopard installed on my machine, and I switch between them all the time (I develop for compatibility on both platforms). Going into System Preferences and selecting the startup disk every time is quite a pain, it would be great if I could automate this process with a script that I can launch from my dock.

This should work.

Saved as a bash script this fits my needs perfectly. –  fredley Oct 28 '11 at 16:39
