How to Tell What Version of Linux You Are Running

Linux is an open-source operating system that has been around for over two decades. With so many distributions (distros) available, it can be overwhelming to determine which version of Linux you are running. In this article, we will guide you through the steps to identify the version of Linux you are currently running.

Step 1: Check Your System Information

To start, you need to check your system information. This will give you an idea of the version of Linux you are running. Here are the steps to follow:

• Open a Terminal: Open a terminal on your system. You can do this by searching for "Terminal" in your system’s application menu or by pressing Ctrl+Alt+T on your keyboard.
• Type lsb_release -a: Type lsb_release -a in the terminal and press Enter. This command will display information about your Linux distribution, including the version.
• Check the Version: Look for the version number in the output. It should be displayed in the format Linux <distro_name> <version> (x.x.x).

Step 2: Check Your Package Manager

To determine the version of Linux you are running, you need to check your package manager. Here are the steps to follow:

• Open a Terminal: Open a terminal on your system.
• Type dpkg -l: Type dpkg -l in the terminal and press Enter. This command will display a list of installed packages, including their version numbers.
• Check the Version: Look for the version number in the output. It should be displayed in the format Package <package_name> <version>.

Step 3: Check Your Kernel Version

To determine the version of Linux you are running, you need to check your kernel version. Here are the steps to follow:

• Open a Terminal: Open a terminal on your system.
• Type uname -r: Type uname -r in the terminal and press Enter. This command will display the kernel version.
• Check the Version: Look for the version number in the output. It should be displayed in the format Linux <distro_name> <version>.

Step 4: Check Your System Logs

To determine the version of Linux you are running, you need to check your system logs. Here are the steps to follow:

• Open a Terminal: Open a terminal on your system.
• Type journalctl -u systemd: Type journalctl -u systemd in the terminal and press Enter. This command will display system logs, including the version number.
• Check the Version: Look for the version number in the output. It should be displayed in the format Systemd <version>.

Step 5: Check Your System Configuration Files

To determine the version of Linux you are running, you need to check your system configuration files. Here are the steps to follow:

• Open a Terminal: Open a terminal on your system.
• Type cat /etc/os-release: Type cat /etc/os-release in the terminal and press Enter. This command will display system configuration files, including the version number.
• Check the Version: Look for the version number in the output. It should be displayed in the format <distro_name> <version>.

Significant Points to Keep in Mind

• Linux Version: The version of Linux you are running is usually indicated by the Linux keyword in the output of the commands above.
• Package Manager: The package manager is usually indicated by the dpkg or apt keyword in the output of the commands above.
• Kernel Version: The kernel version is usually indicated by the uname -r command.
• System Logs: The system logs are usually indicated by the journalctl command.
• System Configuration Files: The system configuration files are usually indicated by the cat command.

Conclusion

Determining the version of Linux you are running can be a bit tricky, but following these steps will help you identify the version. Remember to check your system information, package manager, kernel version, system logs, and system configuration files to get an accurate answer. With practice, you will become more comfortable with these commands and be able to identify the version of Linux you are running with ease.
