But that gives me:-
/sys/class/net/enp0s25/address:90:1b:0e:06:bc:91
/sys/class/net/lo/address:00:00:00:00:00:00
and I don't know which device corresponds to my LAN IP address. More
significantly if my wired connection is up too there will be three
lines returned. I want to link the above output to the IP address
returned by 'hostname -i'.
