I have been given access to what was called a "Linux server"

The problem is I am not told if its CeentOS, Red Hat, etc

Is there a simple command that will tell me the version of Linux, no matter what the version of Linux you are running?

Thanks

uname -a will give you the kernel version and architecture; can probably guess from the version the distribution
if it's a red hat or variant, you can do cat /etc/redhat-release and it will show the OS version

cat /proc/version

could also help.

(Not only) on Ubuntu you can try

cat /etc/issue

if you didn't modify the content of this file too much, that is.

In redhat & centos, Use this command dmesg | sed -n '3p'
It will show Linux distro, version details as well as kernel version.
In Ubuntu & Debian, Use this command dmesg | sed -n '4p'
