Open a terminal program (get to a command prompt) and type uname -a.

This will give you your kernel version, but might not mention the distribution your running.

To find out what distribution of linux your running (Ex.

Ubuntu) try lsb_release -a or cat /etc/*release or cat /etc/issue* or cat /proc/version.

How do I know which Linux distribution I have?

How do I find the RHEL version?

You can see the kernel version by typing uname -r . It’ll be 2.6.something. That is the release version of RHEL, or at least the release of RHEL from which the package supplying /etc/redhat-release was installed. A file like that is probably the closest you can come; you could also look at /etc/lsb-release.
