Macのネットワーク設定をコマンドラインからやりたい

ネットワークの設定をコマンドからやりたかったので．．．

OSXでは`networksetup`コマンドで可能そうです．

```shell-session
uraura@rosemary$ networksetup -listallnetworkservices
An asterisk (*) denotes that a network service is disabled.
Thunderbolt Ethernet
Wi-Fi
iPhone USB
Bluetooth PAN
Thunderbolt Bridge

uraura@rosemary$ networksetup -getsocksfirewallproxy Wi-Fi
Enabled: No
Server:
Port: 0
Authenticated Proxy Enabled: 0

uraura@rosemary$ sudo networksetup -setsocksfirewallproxy Wi-Fi localhost 1080
Password:

# 設定するとデフォでONになります
uraura@rosemary$ networksetup -getsocksfirewallproxy Wi-Fi
Enabled: Yes
Server: localhost
Port: 1080
Authenticated Proxy Enabled: 0

# OFFにしたいだけなら
uraura@rosemary$ sudo networksetup -setsocksfirewallproxystate Wi-Fi off

uraura@rosemary$  networksetup -getsocksfirewallproxy Wi-Fi
Enabled: No
Server: localhost
Port: 1080
Authenticated Proxy Enabled: 0
```

ちなみに上記はGUIだとこのあたり

オプションめっちゃある．．．たぶんこれらの項目がすべて設定できるようになってるんだろうけど確かめる気力はない．．．
