Wanna know version of RedHat installed?

Wanna know exactly what version of redhat/centos/enterprise linux you are running?

Normally on any unix flavors if you do "uname -a" you get all the details along with servername, o/s build details.

If yo do the same on redhat, it will not tell you what version you are running.
$uname -a
Linux servername 2.4.21-47.ELhugemem #1 SMP Wed Jul 5 20:30:35 EDT 2006 i686 i686 i386 GNU/Linux

To know the version on Redhat/Centos/Oracle Enterprise Linux you need to ...
$cat /etc/redhat-release
Red Hat Enterprise Linux AS release 3 (Taroon Update 8)

$cat /etc/enterprise-release
Enterprise Linux Enterprise Linux AS release 4 (October Update 4)

Good Luck and Cheers!
