===================
networksetup -listnetworkserviceorder
produz resultados semelhantes, mas exibe "uma lista de serviços de rede na ordem em que são contatados para uma conexão" ou mostra os serviços na mesma ordem que as Preferências do Sistema.
networksetup
não inclui dispositivos como os dispositivos vmnet1
e vmnet8
usados pelo VMWare.
Você pode ver mais informações sobre os en
dispositivos executando defaults read /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist

Além do que iklier disse sobre o nome do dispositivo Wi-Fi estar en0
em laptops sem porta ethernet e en1
em Macs com uma única porta ethernet, também está en2
em pelo menos alguns Mac Pros com duas portas ethernet.
