How to Tell What Version of Linux You Are Running

Introduction

Ever wonder which version of Linux you’re running? Knowing your Linux version can be crucial, whether you’re troubleshooting, installing software, or just curious. This guide will walk you through simple methods to find out your Linux version easily.

What is Linux, and how does it work?

Linux is an open-source operating system based on the Linux kernel.

An open-source web server for Linux is known for its stability, security, and flexibility, making it a popular choice for hosting websites on servers, desktops, and embedded systems. Unlike proprietary systems, Linux is developed collaboratively by a global community and allows users to modify and distribute its source code.

What is Linux, and how does it work

Checking Kernel Version

One of the quickest ways to check your Linux version is by using the name Command.

Open your terminal and type:

uname -a

This Command shows detailed information about your system. It includes the Linux kernel version, which is the core of your Linux operating system. While this won’t tell you the exact distribution name, it helps get kernel details.

Checking the /etc/os-release File

Viewing Distribution Information

Most modern Linux distributions include the /etc/os-release file, which provides information about the operating system. To view this file, type:

Cat/etc/os-release

This Command will display the distribution name, version, and more information. It’s a straightforward way to get detailed data about your Linux setup.

Using the lsb_release Command

Getting Distribution Details

If you have lsb_release installed, it comprehensively summarizes your Linux distribution. To use it, type:

lsb_release -a

This Command gives you a clean overview of your Linux distribution, including the release number and codename. It’s perfect for getting all the necessary distribution details in one go.

Viewing /etc/release Files

Distribution-Specific Files

Some Linux distributions maintain specific files in the /etc/ directory that contain version information. Depending on your distro, you might find:

  • /etc/redhat-release for Red Hat-based systems
  • /etc/issue for general information
  • /etc/debian_version for Debian-based systems

To check these files, use commands like:

cat /etc/Redhat-release

Or

cat /etc/debian_version

These files offer a quick way to find your Linux version, especially if you know which distribution you use.

Which version of Linux is best for securing your server?

The best version of Linux for securing your server depends on your specific needs. Popular choices include Ubuntu LTS for stability and regular updates, CentOS/RHEL for enterprise-grade security, and Debian for its robust package management and security features. Each offers strong security options, but selecting the right one depends on your environment and requirements.

Conclusion

Knowing your Linux version is essential for system management and troubleshooting. These simple commands and files make it easy to find out which version of Linux you’re running. Whether you’re checking the kernel or distribution details, these methods cover all your needs.
