Finding Bluetooth MAC Address from the command line

The btinfo command displays a lot of information about your bluetooth adapter, including it's MAC Address.

> btinfo      

To display only the Bluetooth MAC Address run btinfo with the "-a" switch.

> btinfo -a   

btinfo is not available on your system out of the box.  It's a part of the freeware Bluetooth command line tools suite.
