There are several ways of knowing the jeff the killer anime of Linux you are running on your machine as well as your distribution name and kernel version plus some extra information that you may probably want to have in mind or at your fingertips. Therefore, in this simple yet important guide for new Linux users, I will show you how to do just that.
Doing this may seem to be relatively easy task, however, having a good knowledge of your system is always a recommended practice for a good number of reasons including installing and running the appropriate packages for your Linux version, for easy reporting of bugs coupled with many more.
With that said, let us proceed to how you can figure out information about your Linux distribution. We will use uname command, which is used to print your Linux system information such as kernel version and release name, network hostname, machine hardware name, processor architecture, hardware platform and the operating system.
In the preceding command, the option -o prints operating system name and -r prints the kernel release version.
You can also use -a option with uname command to print all system information as shown:. Simply type the command below to display some of your system information including the Linux kernel version:.
In this article, we walked through a brief and simple guide intended to help new Linux user find out the Linux version they are running and also get to know their Linux distribution name and version from the shell prompt.
Perhaps it can also be useful to advanced users on one or two occasions. Lastly, to reach us for any assistance or suggestions you wish to offer, make use of the feedback form below.

Retrieved 15 February It can be useful to know the version number of the kernel i. Not only is it instructive in itself, but it can also be helpful in diagnosing and upgrading systems because each release of the kernel contains some differences, sometimes minor and sometimes substantial. Fortunately, it is extremely easy to obtain this information, and, in fact, there is a choice of at least five ways to do it.
Moreover, each of these techniques can also be used, with slight modification, to obtain additional information about a system. Perhaps the easiest is to use the uname command which reports basic information about a system's hardware and software with its -r optionthat is.
This method has the advantages that only a minimal amount of typing is required and that it provides just information about the kernel with no extra output to search through.
This can be easily accomplished by using the cat command which is commonly used to read and concatenate filesi. A third way is to use the rpm i. This method has the advantage that it provides output information solely about the kernel. However, it has the disadvantage that it only works on distributions i.
A fourth method is to look at the contents of the dmesg command, which is used to report information about the system as it boots up i. Because dmesg generates a large amount of output, it is convenient to first transfer that output using a pipe represented by the vertical bar character to the grep filter with the word Linux as an argument in order to display only lines that contain that word and thus the kernel version information as follows:.
The disadvantages of this method are that it requires some extra typing and that there is still a lot of output to search through even though it has been greatly reduced through the use of the grep filter.
A fifth method is to look in directories in which the kernel or its source code i. There can be differences among systems, and some systems might not contain the source code. However, the kernel frequently resides in the boot directory, and thus its name, which includes the version and release numbers, can be found by using the ls command which lists the contents of a directory with that directory as an argument as follows:.
This command will likely produce several references to the version of the currently installed and running kernel. Among them should be an entry such as vmlinuz Created May 31, All Rights Reserved. Perhaps the easiest is to use the uname command which reports basic information about a system's hardware and software with its -r optionthat is, uname -r This method has the advantages that only a minimal amount of typing is required and that it provides just information about the kernel with no extra output to search through.

This section describes Linux kernel development and release models belowstable and long-term supported LTS kernels including why all Android devices should use stable releases instead of cherry picking patcheskernel configuration and hardeningrequirements for interfaces and the modular kernels introduced in Android Okernel debugging and network testingand SquashFS.
The Linux kernel is the largest collaborative software project ever. Inover 4, different developers from over different companies contributed to the project and there were 6 releases, each containing between 12, and 16, different changes. At the end of the size of the Linux kernel was just over 56 thousand files, consisting of 22 million lines of code, build scripts, and documentation kernel release 4. While the Linux kernel contains code for all the different chip architectures and hardware drivers it supports, an individual system runs only a fraction of the codebase.
An average laptop uses around 2 million lines of kernel code from 5 thousand files to function properly, while the Pixel phone uses 3. With the release of the 2. In this model, a new release occurred every 2 to 3 months, and that release was declared stable and recommended for all users to run. This change in development model was due to the very long release cycle prior to the 2. The numbering of the kernel releases began at 2. The kernel version since then has now moved to 4.
These version numbers are chosen by the maintainer s only to avoid confusion among users caused by higher minor release numbers.

Linux kernel development The Linux kernel is the largest collaborative software project ever.Many Linux distributions provide their own "longterm maintenance" kernels that may or may not be based on those maintained by kernel developers.
These kernel releases are not hosted at kernel. It is easy to tell if you are running a distribution kernel. Unless you downloaded, compiled and installed your own version of kernel from kernel. To find out the version of your kernel, run uname -r :. If you see anything at all after the dash, you are running a distribution kernel.
Please use the support channels offered by your distribution vendor to obtain kernel support. There are several main categories into which kernel releases may fall: Prepatch Prepatch or "RC" kernels are mainline kernel pre-releases that are mostly aimed at other kernel developers and Linux enthusiasts. They must be compiled from source and usually contain new features that must be tested before they can be put into a stable release.
Prepatch kernels are maintained and released by Linus Torvalds. Mainline Mainline tree is maintained by Linus Torvalds. It's the tree where all new features are introduced and where all the exciting new development happens.
New mainline kernels are released every months. Stable After each mainline kernel is released, it is considered "stable.[Tutorial] Upgrade Upstream Update Kernel Version - Kernel Compilation Advance
There are usually only a few bugfix kernel releases until next mainline kernel becomes available -- unless it is designated a "longterm maintenance kernel. Longterm There are usually several "longterm maintenance" kernel releases provided for the purposes of backporting bugfixes for older kernel trees.
Only important bugfixes are applied to such kernels and they don't usually see very frequent releases, especially for older trees. To find out the version of your kernel, run uname -r : uname -r 3.
