Ditto I'm afraid to say. I tried that version and also another version 
similar idea but the 'BUS="usb"...' line was different. Still no go.

Compiling a program is easy enough. You write the program in a text 
editor, save it as a .nxc file then compile it using the command:

nbc filename.nxc -O=filename.rxe

The .rxe file will be in the same directory as the .nxc file.

But how to get the .rxe to the brick... that's the tricky bit!

I even tried tinkering with Bluetooth today to try and get a BT 
connection. Nearly got it. PC can see the brick and the brick can see 
the PC but I'll be damned if I could pair them up and get a connection 
(even using the default passcode of 1234). Something about having to set 
up a virtual serial connection or some such nonsense   :/

I've left a post in an NXT forum that I know the author of the book 'NXT 
Power Programming' (which I bought) frequents, so hopefully he can shed 
some light on it, but you're right, even the book (mentioned above, 
written by the guy who upkeeps NXC) talks about the GUI more than the 
commands...

I'm about to join you on that soon...  :D
