How to get MAC address from ifconfig

How can I get MAC address on my notebook? I know I must input ifconfig, but I don't see the line "HWaddr". This is my output:

$ sudo ifconfig
enp3s0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 ether 28:d2:44:e8:30:6a txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

Where is MAC address here?

Your mac address are being shown under ether lines.

ether 28:d2:44:e8:30:6a 

and

ether 38:b1:db:c7:a5:27

You can even use nmcli to get your mac address:

nmcli device show enp3s0 | grep -i hw

or

nmcli device show wlp4s0 | grep -i hw

both outputs will be similar to:

GENERAL.HWADDR: 38:b1:db:c7:a5:27

Go to System Settings. Select Network. Click on the settings next to your current connection (Wired or Wifi). Then mac address will be available under the name Hardware address. Or you can switch to the tab labelled Identity - MAC Address will be specified there (Ubunutu 18.04)
