How to Check Your RHEL Version

linuxredhatrhel4rhel5rhel6

From the shell and without root privileges, how can I determine what Red Hat Enterprise Linux version I'm running?

Ideally, I'd like to get both the major and minor release version, for example RHEL 4.0 or RHEL 5.1, etc.

You can use the lsb_release command on various Linux distributions:

lsb_release -i -r

This will tell you the Distribution and Version and is a little bit more accurate than accessing files that may or may not have been modified by the admin or a software package. As well as working across multiple distros.

For RHEL, you should use:

cat /etc/redhat-release
