Finding a mac address on an Alienware Steam Machine

Does anyone know how to find the mac address on a Alienware steam machine? I am trying to help someone get their device set up to a schools Ethernet, but they cannot find the mac address.

Press CTRL + ALT + F1-12, this will switch to another TTY. To go back to the SteamOS GUI use the same shortcut. Alternatively you can also leave Steam Big Picture mode and boot in to the GNOME desktop where you can open a terminal

You will be presented with a command line. Login with your account and then run these two commands

ip route list | grep default

This will tell you what the interface name is, it wil be something like eno1, eth0 or WLAN.

After this run the command

ip link | grep -A1 WLAN

- Replace WLAN with the name of the interface.

It will spit out 2 lines of information if you did it correctly.

2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
    link/ether ab:cd:ef:12:34:56 brd ff:ff:ff:ff:ff:ff

The numbers which I underlined will be the MAC address of the currently used network adapter.
