===================
networksetup -listnetworkserviceorder
produce un output simile ma visualizza "un elenco di servizi di rete nell'ordine in cui vengono contattati per una connessione" o mostra i servizi nello stesso ordine delle Preferenze di Sistema.
networksetup
non include dispositivi come i dispositivi vmnet1
e vmnet8
utilizzati da VMWare.
Puoi visualizzare ulteriori informazioni sui en
dispositivi eseguendo defaults read /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist

Oltre a quanto detto da iklier in merito al nome del dispositivo per il Wi-Fi en0
nei laptop senza una porta ethernet e en1
nei Mac con una singola porta ethernet, è presente anche en2
in almeno alcuni Mac Pro con due porte ethernet.
