If you want to know what version of Redhat you are running:

Code:
cat /etc/redhat-release

$cat /etc/redhat-release
Red Hat Enterprise Linux AS release 4 (Nahant Update 7)

the redhat-release has rel 4. but it does not display 4 anywhere.. in the output of uname -r
$ red-devl:/home/sudhirsb> uname -r
2.6.9-78.0.8.ELsmp

what actually does uname -r display.

find redhat release number..

what is the difference between the redhat release 4 and kernel version ? is kernel version a kind of sub-release number ?

Old 01-22-2009
No, the kernel version is the release number of the kernel / the OS. The RedHat release number is a counter defined by RedHat to differentiate between their releases of software bundled together with the OS.
