macOSのコマンドラインからネットワークの設定を大体自動でやる

Last updated at 2021-04-16Posted at 2021-04-11

macOSでコマンドラインからネットワークの設定をやりたかったのですが、コマンドが長かったので自動化しました。
vlanはvlan0を指定すると、vlanインターフェースを消せます。

ipの部分を算出できるように改良するかもしれないです。

change.vlan.sh

#!/usr/bin/bash

old_vlan=$(ifconfig | grep vlan: | cut -c 8- | sed 's/parent.*//')
if [ -n "$old_vlan" ]; then
  networksetup -deleteVLAN vlan0 en5 $old_vlan
fi
read -p "vlan ID:" vlan
if [ $vlan = 0 ]; then
    exit $status
fi
networksetup -createVLAN vlan0 en5 $vlan

change.ip.sh

#!/usr/bin/bash

read -p "plz select interface(LAN:0,Wi-Fi:1) : " int
if [ $int == 0 ]; then
    read -p "plz select add type(DHCP:0,Manual:1) : " add_type
    if [ $add_type == 0 ]; then
        networksetup -setdhcp "USB 10/100/1000 LAN"
    else
        read -p "plz insert address : " address
        read -p "plz insert subnet : " subnet
        read -p "plz insert gateway : " gateway
