How to find out Red Hat Version

[mohitanchlia]

I did uname -a and got the following:

Linux build.s.iit.com 2.6.9-22.ELsmp #1 SMP Mon Sep 19 18:00:54 EDT 2005 x86_64 x86_64 x86_64 GNU/Linux

I don't know what to make of it. How do I know which Linux OS and what version is being run. I know for sure Red Hat is installed on this machine.

Have you tried this?

Thanks that helps. I get Red Hat Enterprise Linux ES release 4 (Nahant Update 2). Is that the only way to tell?

There are several ways, but "cat /etc/redhat-release" provides the info you asked for i.e. The OS, version and patchlevel. On some distros you use "cat /etc/{distro}-version", "cat /etc/issue", "cat /etc/lsb_release".
