# list physical network interfaces
ls -l /sys/class/net/ | egrep -v 'virtual|total' | awk '{print $NF}' | awk -F/ '{print $NF}'

# list physical network interfaces mac addresses
for i in $(ls -l /sys/class/net/ | egrep -v 'virtual|total' | awk '{print $NF}' | awk -F/ '{print $NF}'); do ip addr show dev $i | awk '/ether/{print $2}'; done
