List your MACs address

List all MAC addresses on a Linux box. sort -u is useful when having virtual interfaces.

Terminal - Alternatives
lsmac() { ifconfig -a | sed '/eth\|wl/!d;s/ Link.*HWaddr//' ; }
cat /sys/class/net/eth0/address
ifconfig eth0 | grep -o -E '([[:xdigit:]]{1,2}:){5}[[:xdigit:]]{1,2}'
for f in /sys/class/net/*; do echo -e "$(basename $f)\t$(cat $f/address)"; done

Requires sysfs mounted on /sys - may only be useful for Linux systems.

Could also use "printf '%-8s %s\n' $(basename $f) $(cat $f/address)" instead of echo.

cat /sys/class/net/*/address

No need for the ls -r and a sort is also not really needed.
