Find real Version of Redhat Installed

uname -a will show you the kernal discription and type

ie. Linux rh-64.test.dev.ldn 2.6.18-92.el5 #1 SMP Tue Apr 29 13:16:15 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux


but to find the actual version of Red Hat you are running

more /etc/redhat-release

i.e Red Hat Enterprise Linux Server release 5.2 (Tikanga)


Cheers
