![]() ![]() We hope this article has helped you understand how to get the kernel version in Linux and related concepts and methods. Knowing the kernel version is essential for troubleshooting issues, checking compatibility with software or hardware, and updating the system. Each method has its advantages and disadvantages, depending on your needs. In conclusion, there are several ways to get the kernel version in Linux, including using the uname command, checking the /proc/version file, using the /etc/os-release file, and using the lsb_release command. This will display the release version in the format: Release: x.y.zįor example, if you run the lsb_release -r command on a system with kernel version 5.4.0-84-generic, the output will be: Release: 20.04 Conclusion ![]() To check the kernel version using the lsb_release command, open a terminal and run the following command: lsb_release -r ![]() The lsb_release command displays LSB (Linux Standard Base) information about the system, including the distribution and release version. VERSION_ID="20.04" Method 4: Using the lsb_release Command This will display the version information in the format: VERSION="x.y (distro)"įor example, if you run the grep VERSION /etc/os-release command on a system with kernel version 5.4.0-84-generic, the output will be: VERSION="20.04.3 LTS (Focal Fossa)" To check the kernel version using the /etc/os-release file, open a terminal and run the following command: grep VERSION /etc/os-release The /etc/os-release file contains information about the operating system and distribution. This will display the kernel version along with other information in the format: Linux version x.y.z- () (gcc version ) #1 SMP įor example, if you run the cat /proc/version command on a system with kernel version 5.4.0-84-generic, the output will be: Linux version 5.4.0-84-generic (gcc version 9.3.0 (Ubuntu 9.3.0-17ubuntu1~20.04)) #94-Ubuntu SMP Thu Aug 26 20:27: Method 3: Using the /etc/os-release File This information can be obtained through the uname command. To check the kernel version using the /proc/version file, open a terminal and run the following command: cat /proc/version There are several commands/ways to check the kernel version running on your Linux system. ![]() This file contains the kernel version, build date, and other information. This will display the kernel version in the format x.y.z, where x is the major version, y is the minor version, and z is the patch level.įor example, if you run the uname -r command on a system with kernel version 5.4.0-84-generic, the output will be: 5.4.0-84-generic Method 2: Checking the /proc/version FileĪnother way to check the kernel version in Linux is to read the /proc/version file. To use the uname command, open a terminal and run the following command: uname -r This command displays various system information, including the kernel version. The easiest and quickest way to get the kernel version in Linux is to use the uname command. We will also cover related concepts and methods that may help clarify the topic. In this article, we will explain how to get the kernel version in Linux using various methods. Knowing the kernel version is useful when troubleshooting issues, checking compatibility with software or hardware, and updating the system. The Linux kernel is the core component of the operating system that interacts with the hardware and manages system resources. For example, there is an 18.04.4 point release as of February 2020, which includes an updated 5.3.x kernel but is also considered LTS, exactly like the original GA 4.15 kernel in 18.04.As a Linux user or administrator, you may need to know the version of your kernel at some point. Another option for customers is to use point releases. HWE kernel customers are recommended to upgrade to a newer LTS release that supports their hardware and/or software needs as soon as it is available. Customers who need the latest hardware support capability can install the latest HWE kernel such as the ones contained in interim releases, keeping in mind the shorter support lifespan associated with these kernels (9 months). Canonical also provides interim operating system releases with updated kernels every 6 months.įor customers and business partners that don't have specialised bleeding-edge workloads or latest hardware needs, the latest LTS release "-generic" kernel is the best option for them such as the 4.15 default kernel in Ubuntu 18.04 LTS. Canonical provides long-term support (LTS) kernels for Ubuntu LTS releases. ![]()
