In the above example, the Linux kernel is 5.4. You'll now see which Linux kernel you're using. srcversion then gets generated for all modules, including those without MODULEVERSION set: modinfo srcversion: How do I generate this from my source The srcversion file is only present when if one of the above holds. The command uname -r shows the version of the Linux kernel that you're currently using. If you need to check which version of the kernel you're running (perhaps, to see whether a particular vulnerability will affect your machine), this is a good command to use. To check the kernel version using the /proc/version file, open a terminal and run the following command: cat /proc/version. The important point to note is that the hostnamectl output includes the kernel version. This file contains the kernel version, build date, and other information. Another way to check the kernel version in Linux is to read the /proc/version file. The uname command can be used to print out the kernel version, hardware type, processor, operating system and various other information. Method 2: Checking the /proc/version File. The distribution is what you are thinking of as "the OS" and the distros vary quite a bit. To enable it, either: set MODULEVERSION for the module. Linux: Get Kernel Version Mohamed Ibrahim Objective: Find out the kernel version / release that is currently running on any Linux distribution. See in Linux Land, the OS is the kernel and it's toys. Download and install two RPMs matching your system: kernel-debug-debuginfo-.rpm and. Not all distros install the LSB packages, but those that do, like Mint, will have a file named /etc/os-release and one named /etc/lsb-release. Use the uname -r command to identify the running Linux kernel version. Redhat, Fedora, CentOS, SuSE, openSuSE all have a file named like that - /etc/redhat-release and /etc/centos-release. rw- 1 root root 7712560 /boot/vmlinuz-4.13.0-45-genericĪnother place to look is in files named /etc/*-release, if such exist. Here is how I output the name, release, and version of the kernel when running Ubuntu 22.04 (jammy) on WSL2 : 1 uname -kernel-name or uname -s Linux uname -kernel-release or uname -r 5.10.16. For example, on my Linux Mint 19 system, the kernels are in /boot/: ~ $ ls -ltr /boot/vmlinuz* If you really are only interested in the version of the kernel and you really don't have clues about which distro you're looking at, I would start by looking for kernel itself and hope the distro named it with it's version. Is this related to the version of GCC that was used to build a the currently running kernel binary, as shown in the output of cat /proc/version The Linux kernel and GCC are separate projects-they're not released together. Each distribution identifies itself to the world in it's own way, though there are some conventions. There's no one file you could read that would tell you this on every Linux system you might look at.
