> /sbin/ifconfig $1 | grep "inet addr" | awk -F: '{print $2}' | awk '{print
> $1}'

To make it a bit less ancient:

========
/bin/ip -o addr show | grep inet | awk '{print $4}' | awk -F/ '{print $1}'

or just for eth0:

/bin/ip -o addr show eth0 | grep inet | awk '{print $4}' | awk -F/ '{print $1}'
========
 
This might be an interesting article to read, regarding ifconfig:

Further interesting peace of information regarding linux/iptables 
(section 'Mythbusting time') see: http://inai.de/links/iptables/

I hope this information may be usefull to you.
