How to Check Linux Kernel Version with Terminal Command Line

Whenever I heard the word Kernel before using Linux, I always thought of the Corn Kernels. But Kernels in Linux have a totally different meaning. Linux Kernel is the core compojnent of the system, which manages the communication between the system and the software.

Every Linux distro comes with a different Kernel version. You must know the kernels for different reasons for installing softwares like Handbrake or code editors. I use various methods to check the Kernel version in Linux. I am listing all of these ways in this blog post. Here you go:

How to Check Linux Kernel Version

Method #1 – Find Kernel Details using the uname command

uname is the simplest command in Linux that prints out the Kernel version. To run this command, open the Terminal window with the “Ctrl + Alt + T” key combination on your keyboard. Type the following command and press ENTER to check the Linux kernel Version.

uname -r

This command will display the kernel version. It may look like this: 6.5.0-35-generic

In this kernel version, the numbers explain the details about the Kernel itself.

• 6 – Is the Kernel version
• 5 – Is the Major Revision of the Kernel
• 0 – Minor revision ( In this case, no minor revision has been made )
• 35 – This is the number that identifies the Bug fix.
• generic – This highlights the type of Kernel or the OS release. As this is a personal-use desktop version, it says generic.

 

Method #2 – Use /proc/version file for Linux Kernel

Now, I am going to show you the second method. The /proc/version/ command will help you check more detailed information about the current and active Kernel on your desktop. Here are the steps that you need to follow.

Open the Terminal and type or paste the following command.

Cat/proc/version

This will show the Kernel in detail. Here is an example from my system.

Linux version 6.5.0-35-generic (buildd@lcy02-amd64-079) (x86_64-linux-gnu-gcc-12 (Ubuntu 12.3.0-1ubuntu1~22.04) 12.3.0, GNU ld (GNU Binutils for Ubuntu) 2.38) #35~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Tue May 7 09:00:52 UTC 2

The kernel version is 6.5.0-35-generic, as mentioned in the output.

 

Method #3 – Use the dmesg Command to Find Linux Kernel Details

DMESG is an advanced command that shows detailed information about the Kernel. This command is paired with a variety of parameters to access the Kernel and add messages to it. This is meant for advanced users, and you should use it with caution. Just type or paste the following command in the Terminal.

sudo dmesg | grep Linux

You can refer to the screenshot to see the details of the Kernel that my Zorin OS is running on. Fascinating, isn’t it?

 

Method #4 – Hostnamectl to Find Linux Kernel Version

Hostnamectl is a common command that has numerous parameters and used for a wide range of operations. You can use this command and find the kernel version. Here’s how to use this command in Linux Terminal.

hostnamectl | grep Kernel

You can see the simple output of the Kernel in the screenshot attached here. 

 

Frequently Asked Questions

#1 – What is Linux Kernel?

Conclusion 

It’s very easy to find the kernel version of the Linux distribution that you are using. It works perfectly fine with all of the Linux Distros. I’ve used these commands on the Zorin OS, which is based on the Ubuntu. If one command does not work in your case, you can surely use the other three commands that I’ve shared. 

As usual, it’s time to wrap up everything. If you are facing any issues, hit me up in the comments and I’ll surely help yo.
