Google from the Command line

This hack allows you to Google search from the command line. However, I'll have to wait until I get back to a Linux machine before I can test this.
Actually, I now have the impression this is for Windows (DOS) as in Linux it's called the Terminal. Anyway, might still be useful
I've just tried this on a Windows machine and it's very, very good. For example, try "/find pizza castletroy limerick ireland"
This is the address to use.
