I want to determine the MAC-address of my Wi-Fi interface on a Raspberry Pi Z W running Raspbian Lite.
Is there a command that I can run to tell me this? Is there a device in the /proc
tree that will disclose it?

Enter in terminal/console ifconfig wlan0
At the end of the first line should be the hardware address aka MAC.
Here a sample output (German locale):
pi@RasPi0w-1:~ $ ifconfig wlan0
wlan0 Link encap:Ethernet Hardware Adresse b8:27:eb:xx:xx:xx
...
The following is a fragment of a bash script I use to determine the MAC of Ethernet, or if this does not exist of WiFi (for Pi Zero W).
It does not rely on ifconfig
or any other method of detecting allocated IP, and just needs the system to detect the networking hardware.
This works for Jessie, Stretch or Buster
# Find MAC of eth0, or if not exist wlan0
if [ -e /sys/class/net/eth0 ]; then
MAC=$(cat /sys/class/net/eth0/address)
elif [ -e /sys/class/net/enx* ]; then
MAC=$(cat /sys/class/net/enx*/address)
else
MAC=$(cat /sys/class/net/wlan0/address)
fi
Basically you could use MAC=$(cat /sys/class/net/wlan0/address)
to find the MAC of inbuilt WiFi on Pi3 or Pi Zero W.
MAC=$(cat /sys/class/net/wlx*/address)
should work on WiFi dongles on Stretch, but you could easily adapt the above to work on both Jessie or Stretch for WiFi and Ethernet.
Many distros is replacing ifconfig
with ip
so I would discourage the use of ifconfig
.
To show the wlan0 interface:
ip link show wlan0
or
cat /sys/class/net/wlan0/address
