If you’re navigating the world of Linux, knowing which version you’re using can be crucial for troubleshooting, compatibility checks, or simply satisfying your curiosity. This article will guide you through the various methods to display the Linux version on your system.

Why is Knowing Your Linux Version Important?

Understanding your Linux version is like knowing the engine of a car; it helps you understand its capabilities, limitations, and the available options for upgrades. Each Linux distribution (or distro) comes with its own set of features, packages, and configurations.

Here are a few reasons why you should check your Linux version:

• Compatibility: Ensuring software you wish to install is compatible with your Linux version.
• Support: Different versions receive different levels of support and updates.
• Documentation: Many tutorials and help articles reference specific versions.

Methods to Display Linux Version

1. Using the lsb_release Command

The lsb_release command is the most common way to check your Linux version. It provides detailed information about your distribution.

Steps:

1. Open your terminal.
2. Type the following command and press Enter:

   lsb_release -a
   

Output:

You will see something like this:

Distributor ID: Ubuntu
Description:    Ubuntu 20.04 LTS
Release:        20.04
Codename:       focal

2. Checking the /etc/os-release File

Another method to check your Linux version is by reading the /etc/os-release file, which contains information about the operating system.

Steps:

1. Open your terminal.
2. Use the following command:

   cat /etc/os-release
   

Output:

The terminal will display details similar to:

NAME="Ubuntu"
VERSION="20.04 LTS (Focal Fossa)"
ID=ubuntu

3. Using the uname Command

If you're interested in kernel information rather than the distribution, the uname command can help you.

Steps:

1. Open your terminal.
2. Enter the command:

   uname -r
   

Output:

This will show you the kernel version, like:

5.4.0-54-generic

4. Using the hostnamectl Command

If your system uses systemd, you can utilize the hostnamectl command to get version information along with other system details.

Steps:

1. Open your terminal.
2. Execute the following:

   hostnamectl
   

Output:

You'll get a detailed output like this:

   Operating System: Ubuntu 20.04 LTS
             Kernel: Linux 5.4.0-54-generic

Conclusion

Knowing how to display your Linux version is an essential skill that empowers you to navigate the Linux environment more effectively. Whether you're troubleshooting issues, installing software, or simply exploring, understanding the specifics of your system can make a big difference.
