Question

With this command, I would like one command to get the current mac adress only, and another command to get only the permanent mac. So I have to use a grep expression, but I don’t know what to do.

    $ macchanger -s wlan0
    Permanent MAC: 14:25:47:ff:c4:aa (Twinhan)
    Current MAC: 00:24:54:f0:5c:cc (unknown)

So I would really like to do something like macchanger -s wlan0 | grep … in order to exactly get 14:25:47:ff:c4:aa
And another command to get 00:24:54:f0:5c:cc
Thanks you

Answer 1

To get the ‘Permanent’ line:

macchanger -s wlan0 | awk '/Permanent/ { print $3 }'

To get the ‘Current’ line:

macchanger -s wlan0 | awk '/Current/ { print $3 }'
