Airport Terminal Commands

Geeky fun with the airport command. Just discovered this little thing so I thought I would share.
Add a symbolic link of the Airport command to /usr/sbin which lives in /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport
type this command to create the symbol link:
sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport /usr/sbin/airport
… and type your password
You can run the ‘airport’ at the terminal line prompt to get a help file. Simply type airport to get a list of commands or airport -h.
Typing "man airport" brings up a very vacant manual.
For example if you type airport -I (that's an i) it will print the current wireless status, e.g. signal info, BSSID, port type etc.
