I got it, ifconfig eth0 |grep 'inet addr' |awk '{print $2}'
My main problem now is that I need to get that saved in a variable, and i cant do
VAR = ifconfig eth0 |grep 'inet addr' |awk '{print $2}'
echo $VAR

This example works in a bash environment, just surround your command line in such a fashion:

[sf@steve]$ export TEST=`ifconfig rl0|grep netmask|awk '{print $2}'`
-=[~]=- -=[Wed Jul 06]=- -=[17:18:06]=-
[sf@steve]$ echo $TEST
xxx.xxx.xxx.xxx (replaced for obvious reasons)

You'll have to narrow the search down more if you have virtual IPs bound to the same interface, etc.
