I am trying to grab the mac address for eth0 on centos 5.1 with

ifconfig | grep eth0 | cut -d ' ' -f 5 and I dont get anything.

What am I not doing right?

ifconfig | grep eth0 | cut -d ' ' -f 1 gives me eth0 but anything else
like -f 2, -f 3 etc
I get nothing.


ifconfig -a | awk '/eth0/ {print $5}'

should work even if eth0 is not 'UP'
