Terminal Tip: Scan For Wireless Networks.


I stumbled across a photo in our Flickr group that really peaked my curiosity.  Apparently apple has shipped a binary that lets you view your wireless info, as well as wireless access point information in the terminal.  I had no Idea that this existed, so I asked theshizabox in his comments to fill me in.  He was nice enough to pass along the information, so I thought I would post it here.

The binary resides in this location.

/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport /usr/sbin/airport

In order to use the ‘airport’ command from anywhere in the terminal you need to create a link to it.  You can do it by copying and pasting this code into your terminal.

sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport /usr/sbin/airport

Now for the fun.

You can use the airport command to do a number of things, and you can get the information by typing.  ‘airport -h’. This will give you the help file.  The most notable things you can use is ‘airport -s’ which will scan for all the wireless networks in your area, and ‘airport -I’ which will give you a listing of information about the wireless network you are connected to.
