you can make finding the MAC address even easier by parsing the ifconfig command’s output with the grep command, like this:
ifconfig | grep HWaddr
This will only bring up the line of ifconfig’s output with the MAC address.
Example :
kartook@H4C<3r$ ifconfig | grep HWaddr
eth0 Link encap:Ethernet HWaddr 00:22:19:e5:b3:81
vmnet1 Link encap:Ethernet HWaddr 00:50:56:c0:00:06
vmnet8 Link encap:Ethernet HWaddr 00:50:56:c0:00:07
wlan0 Link encap:Ethernet HWaddr 00:2f:6a:2e:ce:2d
