Esiste un programma di utilità della riga di comando integrato per l'aeroporto e altre reti wifi?

Esiste un'utilità wireless a riga di comando chiamata airport , ma non è nell'utente $ PATH essere in grado di chiamarla senza ricordare dove si trova.

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

in modo da renderlo disponibile sulla linea e metterlo dove realmente appartiene, in Terminale:

 chillin@stack:~$ 
 chillin@stack:~$ 
 chillin@stack:~$ sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport /usr/sbin/airport
 chillin@stack:~$ 

E quando lo chiami, fornisce ottime informazioni sulla rete wireless a cui sei connesso:

 chillin@stack:~$ airport
 Usage: airport <interface> <verb> <options>

         <interface>
         If an interface is not specified, airport will use the first AirPort interface on the system.

         <verb is one of the following:
         prefs   If specified with no key value pairs, displays a subset of AirPort preferences for
                 the specified interface.

                 Preferences may be configured using key=value syntax. Keys and possible values are specified below.
                 Boolean settings may be configured using 'YES' and 'NO'.

                 RequireAdminPowerToggle (Boolean)
                 WoWEnabled (Boolean)

         logger  Monitor the driver's logging facility.

         sniff   If a channel number is specified, airportd will attempt to configure the interface
                 to use that channel before it begins sniffing 802.11 frames. Captures files are saved to /tmp.
                 Requires super user privileges.

         debug   Enable debug logging. A debug log setting may be enabled by prefixing it with a '+', and disabled
                 by prefixing it with a '-'.
