![]() grep: particularly searching for a particular string of characters and showing lines that contain them.| (pipe symbol): Passing the command into the next command.Dmesg : Enables you to read the contents of the kernel buffer.Here we will explain how this commands actually works: The pipe symbol ( | ) is usually near the enter key on most keyboards. In simple terms, you can usually use this command to read messages from device drivers but you can also run it to find the kernel version. Most of the time, the dmesg command is used for printing the kernel’s buffer message. You can type cat or less commands to show the contents of the file: cat /proc/versionĪfter running them, you will see an output similar to this: If you want to access information about the running kernel and check the Linux kernel version, pay attention that they are stored in the /proc/version virtual file. The /proc directory has various virtual files that include information about the system memory, CPU cores, mounted filesystems, and many other data. Kernel: Linux 4.15.0-54-generic Use /proc/version File You can type the grep command to filter out the Linux kernel version: hostnamectl | grep -I Kernel ![]() Running this command will shows something similar to this as an output: But it also shows the Linux kernel version and its distribution: hostnamectl The hostnamect is a part of the systemd and is usually used to query and change the system hostname, displaying information about the system’s network configuration. generic: Linux distro/kernel specific additional info.Additionally, these numbers are all associated with a meaning that we will list in the following: To check the Linux kernel version on your system, you need to type the following command: uname -srmĪfter running this command, something like this will be shown as an output:Īs you can see above in the output, the Linux kernel version is 4.15.0-54 and works as 64-bit. The uname command can show you many system information such as the Linux kernel architecture, name version, and release. So, using these commands, you can learn more info about your operating system, including Linux distro name, version, and kernel details. It’s pretty easy to check the Linux kernel version from the command line.Īlso Read: NextCloud vs ownCloud How to find the kernel version in Linux?īefore we explain different methods to find the kernel version in Linux, you should know that some of these methods will show you the Linux distribution name too. Or you might be dealing with a hardware-related issue that requires you to find the Linux Kernel version. For example, you may discover a new security vulnerability affecting older kernel versions, and so you want to find out whether your kernel is vulnerable or not. You might need to find the kernel version running on your GNU/Linux operating system for some reason. The kernel handles the system’s resources and works as a bridge between the system’s hardware and software. The kernel is the main component of an operating system, whether Mac OS, Linux, or windows. command line command prompt Development kernels Do it yourself Kernel Kernel Version Linus Torvalds Linux Linux 3.14.7.2 What are the KVM-powered Virtual Private Servers? What is the kernel version? I hope this helps explain Linux Kernel versions. rpm -q kernel (If you arte running Red Hat package manager).How to tell which Linux Kernel you are running? Since the Linux Kernel is constantly being improved and revised a revision number(5) is added when smaller changes are made. Once a development Kernel is thoroughly tested and deemed stable is will be given an even number x.1.x → x.2.x or x.3.x → x.4.x ![]() Development kernels are not fully tested and can be unstable. Development Kernels are odd and production kernels are even. The second number(14) shows the minor revision. The first number(3) is the major revision to the Linux Kernel.
