[ale] Need AWK Guru input

[terrorpup at gmail.com (Chuck Payne)]

Guys,

I am working on adding servers to my Satellite server, and I like to
be able to get in with a script and call on the following

/etc/redhat_release

But I only want to get the number, so that I can see if it RHEL 4 or
5, I been trying to do with awk, but I am not able to get anything,
what is the best way to only put numbers?
