As we know, Linux systems have many variants and multiple outcomes to resolve any program and issue.

Similarly, we have multiple ways to find out which OS version has installed in our system i-e;

• Through Graphical User Interface
• Through Command-line Interface

Let’s check it practically:

How to Check OS Version through GUI in Linux

To check the version of an operating system via a graphical user interface is quite handy and easy. There are just a few steps you should know.

(Note: I am working on Linux Mint system, the process is same for all Linux distributions)

Or you can also run:

2- proc Command
The proc command is also helpful to find Linux OS versions. Run the mentioned command on terminal:

3- os-release Command
OS information can also be fetched through os-release files by executing command:

4- /etc/issue File
Linux distribution has /etc/issue text file that keeps system’s version information. You can fetch data on screen through following command:

5- hostnamectl Command
The hostnamectl command is basically used to check or edit system host names. But it also displays the OS version with mentioned details. Type in terminal:

Conclusion

It is very important for the users to know about the system they are working on. Many approaches are introduced on Linux systems to display OS versions on screen i-e; either to do it via GUI or Command-line interface. This guideline is all about how to find OS version in Linux. We have seen further utilities that help to print Linux information in the command-line terminal.
