The Linux kernel version is the core component of the Linux operating system. It serves as the intermediary between the hardware and the software layers of the system, providing essential functions such as process management, memory management, device management, and system calls.<\/p>\n

It also enables multi-tasking, where multiple processes can run at the same time, and time-sharing, where the CPU time is shared between running processes.<\/p>\n

\n

The Linux kernel is also responsible for providing security features, such as access control, memory protection, and user management. It ensures that only authorized users can access system resources and that processes cannot interfere with other processes’ memory.<\/p>\n<\/div>\n

\n

A Linux kernel is composed of three key components: the process scheduler, the memory manager, and the device driver. Understanding the role of the Linux kernel is essential for ensuring the optimal performance and security of your Linux system<\/a>.<\/p>\n<\/div>\n

\n

Kernel version information is crucial for identifying and resolving issues related to hardware, software, and system stability. Linux distributions are known for their flexibility in customization and support for a range of hardware architectures.<\/p>\n<\/div>\n

\n

As a result, checking the kernel version on a Linux-based system is crucial in determining compatibility between software and hardware components.<\/p>\n

Kernel version<\/h2>\n

Take a look at some few methods for obtaining the kernel version on a Linux system: the uname<\/em> command, dmesg command, the \/proc\/version<\/em> file, and the hostnamectl<\/em> command.<\/p>\n<\/div>\n

uname <\/em>Command<\/h2>\n

This is the first and most common method used to get or obtaining the kernel version on a linux system.\u00a0 The command name is uname.This command prints the kernel release, version, and a few other system-related details.<\/p>\n

Get the kernel version Linux by opening a SSH or terminal and entering the following command.<\/p>\n

uname -r<\/pre>\n
After entering the command below is the output<\/p>\n
[root@testserver1 ~]# uname -r\r\n3.10.0-1160.102.1.el7.x86_64\r\n[root@testserver1 ~]#<\/pre>\n
In the above example, the Linux kernel version is 3.10.0-1160.102.1.el7.x86_64<\/p>\n
You can obtain additional information by adding some of the additional flags to the uname<\/em> command. In order to see all of the available flags for the uname<\/em> command, enter the following command into your terminal.<\/p>\n
uname --help<\/pre>\n
[root@testserver1 ~]# uname --help\r\nUsage: uname [OPTION]...\r\nPrint certain system information. With no OPTION, same as -s.\r\n\r\n-a, --all print all information, in the following order,\r\nexcept omit -p and -i if unknown:\r\n-s, --kernel-name print the kernel name\r\n-n, --nodename print the network node hostname\r\n-r, --kernel-release print the kernel release\r\n-v, --kernel-version print the kernel version\r\n-m, --machine print the machine hardware name\r\n-p, --processor print the processor type or \"unknown\"\r\n-i, --hardware-platform print the hardware platform or \"unknown\"\r\n-o, --operating-system print the operating system\r\n--help display this help and exit\r\n--version output version information and exit\r\n\r\nGNU coreutils online help: <http:\/\/www.gnu.org\/software\/coreutils\/>\r\nFor complete documentation, run: info coreutils 'uname invocation'\r\n[root@testserver1 ~]#<\/pre>\n
Next using dmesg command<\/p>\n
dmesg<\/em> Command<\/h2>\n
\n
Another way to get the kernel version in Linux is to use the dmesg<\/em> command. The dmesg<\/em> command displays the kernel ring buffer messages, including the kernel version.<\/p>\n<\/div>\n
\n
To use the dmesg<\/em> command, open your terminal window and enter the following command.<\/p>\n<\/div>\n
dmesg | grep “Linux version”<\/p>\n
The above command will execute and shows<\/p>\n
[root@testserver1 ~]# dmesg | grep “Linux version”
\n[ 0.000000] Linux version 3.10.0-1160.102.1.el7.x86_64 (mockbuild@kbuilder.bsys.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) ) #1 SMP Tue Oct 17 15:42:21 UTC 2023
\n[root@testserver1 ~]#<\/p>\n
Next is using the \/proc\/version<\/em> File<\/p>\n
Display the \/proc\/version<\/em> File<\/h2>\n
\n
The \/proc\/version<\/em> file contains information about the current kernel version and the build details. This file can be used to get the kernel version in Linux.<\/p>\n<\/div>\n
\n
To display information in the \/proc\/version<\/em> file, open your terminal window and enter the following command.<\/p>\n
cat \/proc\/version<\/p>\n
After entered the above command , output will be looks like<\/p>\n<\/div>\n
[root@testserver1 ~]# cat \/proc\/version\r\nLinux version 3.10.0-1160.102.1.el7.x86_64 (mockbuild@kbuilder.bsys.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) ) #1 SMP Tue Oct 17 15:42:21 UTC 2023\r\n[root@testserver1 ~]#<\/pre>\n
\n
hostnamectl <\/em>Command<\/h2>\n<\/div>\n
\n
The hostnamectl <\/em>command is used to view or modify the system hostname and related settings. This command can also be used to display the Linux kernel version. The hostnamectl <\/em>command is a component of systemd, so it wouldn’t be available on a Linux distribution that isn’t using systemd by default, such as Gentoo.<\/p>\n<\/div>\n
\n
To use the hostnamectl<\/em> command, open your terminal window and enter the following command.<\/p>\n
hostnamectl<\/p>\n
The output of the above command looks like,<\/p>\n<\/div>\n
[root@testserver1 ~]# hostnamectl\r\nStatic hostname: testserver1.gokul.com\r\nIcon name: computer-vm\r\nChassis: vm\r\nMachine ID: 96820b9851c24560b5f942f2496b9aeb\r\nBoot ID: 070f4b7b5f33473cbd1b4dd22d695291\r\nVirtualization: kvm\r\nOperating System: CentOS Linux 7 (Core)\r\nCPE OS Name: cpe:\/o:centos:centos:7\r\nKernel: Linux 3.10.0-1160.102.1.el7.x86_64\r\nArchitecture: x86-64\r\n[root@testserver1 ~]#<\/pre>\n
In the example presented above, the Linux kernel version is 3.10.0-1160.102.1.el7.x86_64.<\/p>\n
I hope above article will clarify about kernel versions how to find using command prompt.<\/p>\n
