ESXKILL Shutdown Script

A little while back, I was looking into getting Power Chute set up for our ESX hosts. The unfortunate news is that APC does not yet support ESX 3.5 U2. While researching this, I came across a script to shut down all guest OSes and then an ESX host, though, which I have slightly modified and deployed to all of my ESX hosts. The original can be found at http://www.tooms.dk/ By copying the script to a location that can be accessed in my PATH, I can quickly log on to each server in the case of disaster and type 'esxkill". This will usually shut everything down gracefully in 5-10 minutes. Here's the syntax:
