How to Find the Linux OS Version Using the Command Line

Linux is an open source Operating System which means that everyone can freely use and modify it. In the Linux operating system there are a lot of distributions or what we are more familiar with the term distributions, some of which are popular Linux distributions, namely Debian, Ubuntu, Arch, Open Suse, CentOS, Fedora and many more.

For some cases there are still many new Linux users who still don’t know complete information about the Linux OS used, such as Linux version, kernal, architectur, etc. There are many ways that we can use to find information about the Linux OS that we use just by using the Command Line or Terminal.
