I had to use ifconfig wlan1 where wlan1 is the interface on my computer (most likely it'll be different on another computer) and change the part where it has adr to addr like this ifconfig wlan1 | head -n 2 | tr -d '\n' | sed -n 's/.*\(00:[^ ]*\).*\(addr:[^ ]*\).*/MAC:\1 - \2/p' ; echo Plus I added an empty line with "; echo" at the end.

I also tried this on another computer but had to change the 00: to the starting hexadecimal values of the MAC address of my interface, like 14: instead. So the whole thing is ifconfig wlan0 | head -n 2 | tr -d '\n' | sed -n 's/.*\(14:[^ ]*\).*\(addr:[^ ]*\).*/MAC:\1 - \2/p' ; echo

@Chrismccoy : on SLES (Suse) @Ronin : You can customize the syntax as needed, great job.

i tryed this : ifconfig | grep -A2 eth | tr -d "\n"| sed 's/\-\-/\n/g'|awk '{print "mac: "$5 " " $7}' | sed 's/addr:/addr: /g' and should work for all network interfaces.

this version should work also for "wlan" interfaces : ifconfig | egrep -A2 "eth|wlan" | tr -d "\n"| sed 's/\-\-/\n/g'|awk '{print "mac: "$5 " " $7}' | sed 's/addr:/addr: /g'
