How to check and confirm the RedHat Linux version

[gab_in]

Hi,

I want to confirm the redhat linux version of our server. I have checked the below three options.
1) cat /etc/redhat-release shows the RHEL( Red hat Linux Enterprise Linux) version Ex: RHEL 4(Nahant Update 6), RHEL 3(Taroon Update 6)

2) cat /proc/version shows the 'Red Hat Linux' version. Ex: 3.2.3-53 , 3.3.3-59 , 3.4.6-8 etc.

3) uname -a which provided the Linux kernel version Ex: 2.4.21-37, 2.4.21-57, 2.6.9-67 etc.

Please let me know where to look for Red Hat Linux versions and what is the meaning of all three in details.

Thanks
Gab

The Red Hat version is indicated by the /etc/redhat-release file. The other informations indicate the kernel version.
