In today’s world, Linux is flourishing. It is a powerful and versatile operating system that powers servers, desktops, and even embedded systems around the world. So, it is essential to check Linux version. The version of the OS and the version of the Linux kernel are some of the information you will need to understand to handle and troubleshoot your Linux systems. In this article, we will cover various ways to find the version of Linux, obtain the version of Linux kernel, and why the information matters regarding system optimization, updates, and software compatibility.
We will also discuss how CyberPanel helps make the administration of Linux systems much more manageable.
Let’s get into the world of Linux!
Why Care About Your Version of Linux?
Whether one is an administrator or developer, understanding Linux is essential. The Linux OS version also determines compatibility with other software, applies security patches, etc. Another reason is that different distros have differing package managers, software repositories, and system utilities, among others. Further, the Linux kernel version impacts hardware compatibility and how the system will perform.
How To Check Linux Version: 6 Methods for Any Linux Distro
There are different ways to check the Linux version. It depends on your Linux distribution.
1. Using /etc/os-release File
The best source to get information on your Linux distribution and version is in the file /etc/os-release. This file contains most Linux distributions.
Get exclusive access to all things tech-savvy, and be the first to receive
the latest updates directly in your inbox.
This file provides you details of your Linux distribution like name, version, and ID. LTS in the above output stands for Long-Term Support. It means that this version will receive updates for an extended period.
2. Using hostnamectl
The hostnamectl is the command that provides you with an easy way to check both the operating system and kernel versions.
In the above output, the Operating System line tells you the distribution and version. And, the Kernel line tells you the Linux kernel version.
3. Using lsb_release -a
This command fives Linux Standard Base (LSB) version information for your system. It is also helpful in situations when you need a quick summary of your Linux distribution.
How To Check The Version of Linux Kernel
Equally important is knowing the version of your Linux kernel. This kernel forms the heart of your operating system and governs how your system interacts with hardware. So, knowledge in terms of the Linux kernel version is useful for certain system issues debugging, verification of compliance for software or hardware, and even improving performance by installing newer versions of kernels.
Using uname -r
This command is essential to specifically check the Linux kernel version.
The above output represents your kernel version. In our case, its version is 5.4.0-104.4.
If you want to view more detailed information, including the kernel version, hardware name, and more. You have to use the -a option then.
Output
Linux my-server 5.15.0-43-generic #46-Ubuntu SMP Thu Jul 7 09:18:29 UTC 2022 x86_64 x86_64 x86_64 GNU/LinuxThe uname -a command gives the following information in detail:
- Kernel version:5.15.0-43-generic
- Architecture: x86_64 – 64-bit system.
- SMP: Allowed for the feature of Symmetric Multi-Processing
Running uname -a shows a complete view of what your kernel version is, together with the architecture and build of your system.
Checking Linux Kernel Version Using /proc/version
The /proc/version file contains detailed information about the kernel version and compiler used to build it.
You will get this output:
Linux version 5.4.0-104-generic (buildd@lgw01-amd64-047) (gcc version 9.3.0 (Ubuntu 9.3.0-17ubuntu1~20.04)) #118-Ubuntu SMP Thu Mar 24 19:46:54 UTC 2022Using neofetch
nofetch is a third-party tool that provides a graphical display of your system’s information.
Checking Kernel Version Using dmesg
The dmesg command does just this: print kernel ring buffer messages. As you work the technique, you may find that dmesg comes in handy when trying to determine the version of the Linux kernel. Due to the immense amount of lines dmesg prints, you should combine its output with the grep command to isolate the kernel version:
Output:
[ 0.000000] Linux version 5.15.0-43-generic (buildd@lgw01-amd64-022) (gcc (Ubuntu 9.3.0-17ubuntu1~20.04)) #46-Ubuntu SMP Thu Jul 7 09:18:29 UTC 2022Using these methods, you can easily determine the version of the Linux kernel installed on your system. The information can be quite helpful during system updates, troubleshooting, and ensuring hardware compatibility. Whether it’s a server environment or a personal machine, you’d like to know the difference between how to check for both the Linux version and the Linux kernel version to have better control and stability of your Linux system.
Best Practices for Managing Your Linux Version and Kernel
- Check periodically for available kernel upgrades to obtain the security patches and performance improvements.
- Track all kernel upgrades and changes for troubleshooting as well as potential rollback activities
- Utilize automation tools such as Ansible or Puppet to track kernel versioning across multiple servers.
- Always back up critical data as well as configurations before kernel upgrade in case some of the data gets lost.
- Test kernel upgrades in staging before deploying it in a production environment.
- System logs and performance metrics that reflect the issues related to updates of the kernel.
- Always be a part of some Linux community or another whereby you can acquire best practices and solutions to many other problems from individuals who have so much experience.
- Leverage the features of CyberPanel, which can help streamline the way you will be managing your Linux server, for example, by monitoring the different versions and updates of the kernel.
