How to find my MAC address on Linux?

The first way

For Linux, you can always use the universal way: the command line!

  1. 1

    You can do so by executing one of these commands.

    $ ifconfig
    enp2s0f0  Link encap:Ethernet  HWaddr b8:88:e3:b0:f3:f0
              UP BROADCAST MULTICAST  MTU:1500  Metric:1
              RX packets:0 errors:0 dropped:0 overruns:0 frame:0
              TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
              collisions:0 txqueuelen:1000
              RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
              Interrupt:16
    
    lo        Link encap:Local Loopback
              inet addr:127.0.0.1  Mask:255.0.0.0
              inet6 addr: ::1/128 Scope:Host
              UP LOOPBACK RUNNING  MTU:65536  Metric:1
              RX packets:1969 errors:0 dropped:0 overruns:0 frame:0
              TX packets:1969 errors:0 dropped:0 overruns:0 carrier:0
              collisions:0 txqueuelen:1000
              RX bytes:198134 (198.1 KB)  TX bytes:198134 (198.1 KB)
    
    wlp3s0    Link encap:Ethernet  HWaddr a4:17:31:79:1e:01

  2. 2

    As you can see, there is a lot of output, but we are only interested in MAC addresses (They are underlined in red).
