Here are 3 different ways to check the current version of Linux you are running:
    1. uname -r
    2. cat /proc/version
    3. hostnamectl

I select the first option.

The first option, uname -r, is a simple command used to display the current Linux kernel version. The uname command displays information about the current system, and the -r option specifically shows the release (version) number of the operating system. When you run uname -r, you'll see output like this:

5.4.0-7634-generic

This tells you the version number of the Linux kernel that's currently running on your system, in this case 5.4.0. The rest of the string, -7634-generic, indicates other information such as the specific build or distribution of the kernel.
