Are you specifically wanting to use a script as opposed to the normal way through the UI?
Also, you'll probably want to upgrade to 6.5.1. It looks like that's probably what you're doing by default if you're downloading the installer from the Portal. I think BP changed how the download page works where it only lets you download the most recent/stable version of each minor version of BP. I just wanted to make sure you don't make the mistake of installing 6.5 because it has several significant issues that were patched in 6.5.1.
