When you're working with Linux, knowing the version you're running is like knowing the road signs on a trip—it's essential for navigating your way through the operating system smoothly. Whether you're troubleshooting an issue, installing software, or just curious, checking your Linux version is straightforward. In this article, we will guide you through various methods to find your Linux version.

Understanding the Basics

Before we dive into the specifics, let’s clarify what we mean by “Linux version.” Each Linux distribution (or "distro") has its version number, which indicates the specific release and its features. Here’s how you can check that version:

Method 1: Using the Terminal

The terminal is your command center in Linux, akin to the cockpit of an airplane. Here are several commands you can use to check your version:

1. Check the OS Version with lsb_release

   This command provides the most straightforward and detailed information about your Linux distribution.

   lsb_release -a
   

   This will output something like:

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

2. Check the Kernel Version with uname

   The kernel is the core of your operating system. To check its version, use:

   uname -r
   

   This might return a version number like 5.4.0-42-generic.

3. View Version Information in the /etc/os-release File

   You can also find version information in the os-release file:

   cat /etc/os-release
   

   This will provide you with a comprehensive overview of your system, including the name and version.

Method 2: GUI Methods

If you prefer a graphical user interface (GUI), most Linux desktop environments have a system settings option that shows the version:

1. Ubuntu and Many Other Distros:

   • Open the Settings application.
   • Navigate to the About section.
   • Here, you will find the version of your Linux distribution displayed clearly.

Method 3: Using the hostnamectl Command

For those using a newer system with systemd, you can use:

hostnamectl

This command not only provides you with the OS version but also information about the kernel and architecture.

Conclusion

Checking the version of your Linux operating system is a simple yet important task that can help you with various aspects of system management. Whether you're using the terminal or a GUI, it's like checking your equipment before a big game—crucial for ensuring everything runs smoothly.

Additional Tips

• Always keep your system updated to the latest version to benefit from security patches and new features.
• Bookmark these commands or notes for quick reference in the future.

By familiarizing yourself with these methods, you'll navigate the world of Linux with confidence. Happy exploring!
