Just curious, why do you cat the file to awk when you can simply pass 
the file name to awk on the command line?
???

It's a wasted process.

How about:

awk '/release 5/ {print "RHEL 5\n"}
	/release 4/ {print "RHEL 4\n"}' /etc/redhat-release

That is assuming that 'release N' is always in that file indicating the 
version.
