Understanding your Linux operating system's version is crucial, whether you're troubleshooting, installing new software, or ensuring compatibility with applications. Just as you wouldn't drive a car without knowing its model, navigating through Linux without knowing your OS version can lead to unnecessary hiccups. This guide will show you multiple methods to check the version of your Linux operating system.

Why Knowing Your OS Version Matters

Before diving into how to find your OS version, let's consider why it’s important:

• Compatibility: Some applications require specific OS versions.
• Updates: Knowing your version helps ensure you have the latest features and security updates.
• Support: Some distributions only support specific versions for a limited time.

Methods to Check Your Linux OS Version

Here are several straightforward ways to find out the version of your Linux OS:

Method 1: Using the Terminal

The terminal is your best friend in Linux, and several commands can help you retrieve the OS version. Here are some common commands:

1. lsb_release Command

The lsb_release command provides detailed information about your Linux distribution. To use it, follow these steps:

1. Open your terminal.

2. Type the command below and press Enter:

   lsb_release -a
   

This will display information like the distribution name, release number, and codename.

2. cat /etc/os-release

Another reliable way to check your OS version is by using the following command:

1. Open your terminal.

2. Type the command below and press Enter:

   cat /etc/os-release
   

This command reads the contents of the os-release file, which typically includes details about the operating system.

Method 2: Graphical User Interface (GUI)

If you prefer a GUI approach, here’s how to check your OS version without using the terminal:

1. Ubuntu:

   • Click on the Settings icon.
   • Navigate to About in the sidebar.
   • You’ll see your OS version displayed under the “OS Name” section.

2. Fedora:

   • Click on Activities in the top left corner.
   • Type About in the search bar and select it.
   • Your version will be shown under "OS".

3. Debian:

   • Go to Applications > System Tools > About this Computer.

Method 3: Using Other System Files

If the above commands don’t work for your specific distribution, you can check other files that might contain version information. Here are two common files to check:

• For CentOS or Red Hat:

  cat /etc/redhat-release
  

• For SuSE:

  cat /etc/SuSE-release
  

Conclusion

Checking the version of your Linux operating system is not only a good practice but also essential for maintaining a smooth computing experience. With various methods at your disposal—using the terminal commands or GUI options—you can effortlessly obtain this vital information.
