How to check the version of Linux? Check Linux Version

Hello guys, welcome back to our simple guide series where we learn about Linux tech and how-tos. Today we are going to learn how to check the version of Linux we are using. 

Table of Contents –

There are many ways to check which Linux version we are using but the question is what exactly you need? Linux kernel version or Linux distribution version. 

Linux kernel acts as the interface between the hardware and processes and performs major operations of the operating system. But Linux kernel is not the operating system itself instead it is the heart of the Linux OS. You can check the version of the Linux kernel which is being used on your system.

The Linux kernel performs major operations of the computer and it is important to know the Linux kernel which you are using. You can check the kernel version by using simple commands which we will discuss further but what exactly are the functions of the Linux kernel? 

Important functions of the Linux kernel are – 

Memory Management – Linux kernel manages memory and all related operations. 

Process Management – CPU management is necessary to determine which process gets to use the CPU and for how long it can use it. There are many scheduling methods which we can discuss in another blog post. 

Device Drivers – Acts as an interface between software processes and hardware components. 

You can read more on Wikipedia about Linux kernels and their complete documentation. Click here.

The other meaning to check the version of Linux can be more about the whole operating system. There is a major difference between the Linux kernel and the Linux operating system. Linux kernel is the core component of the operating system acting as an interface but Linux operating system is made from Linux kernel, GNU tools and libraries, and software combinations.

The output of the above command will be something similar to this, 

linux version check
No LSB modules are available.

Description: Kali GNU/Linux Rolling

Release: 2019.4

Codename: kali-rolling

Linux distribution versions are shown as a piece of descriptive information. From the above output, you can notice that I am using Kali GNU/Linux (Rolling.) 

You may not need so much information and just want to check the Linux version. I am going to show you how to check the version of Linux with the LSB command which displays only the version. 

Type the following command in your terminal, 

# lsb_release -d

The output of the above code will show you what Linux version you are using.

# cat /etc/issue

The above command is used with cat command and the output is given below –

It displays that there are no issues with the operating system and also checks the Linux version for you. 

Conclusion – 

This sums up our tutorial to check the Linux version and determine which package manager we wish to install or perform any operation. By now you also know the basic differences between the Linux kernel and Linux distributions. Make sure to know what version you are exactly looking for. The commands listed above are used on Kali Linux which uses a “#” prompt. Other distributions such as ubuntu, centOs, Mint, OpenSUSE, and more may use a different prompt but commands remain the same.
