How To Find Your Linux Kernel Version
uname -r: Find Linux kernel version.cat / proc / version: display the Linux kernel version in a special file.hostnamectl | grep kernel: For systemd based Linux distributions, you can use hotnamectl to display the hostname and launch the Linux kernel version.
I am using Ubuntu for this article. But these commands were common and can be used on Fedora, Debian, CentOS, SUSE Linux, also known as any other Linux distribution.
1. Find The Linux Kernel Using The Uname Command
uname is the gist of the Linux command to get system files. You can also use it to find out if you are using a 32 bit or 64 bit system.
uname -r 4.4. Means 0–97-generic For this reason, you are using the Linux 4.4.0-97 kernel, and more generally, you should be using the 4.4 Linux kernel.
But what do the other numbers meanIs it okay? Let me explain:
- 4 – kernel version
- 4 – major version
- 0 – minor version
- 97 Error – fix
- generic is a distribution-specific archipelago. For Ubuntu, this means I am using the desktop version. Ubuntu, to find the server version, it will be “Server”.
You can also use the uname command with the -a strategy. If necessary, you will receive additional information about the solution.
uname -a Linux itsfoss 4.4.0-97-generic # 120-Ubuntu SMP September 19 17:28:18 UTC 2017 x86_64 x86_64 x86_64 GNU / Linux - The name of the Linux kernel. If you run the same command on BSD or macOS high, the result may be different.
- itsfoss is the hostname.
- 4.4.0-97-generic – kernel unpacking (as we saw above).
- # 120-Ubuntu SMP Tue Sep 19 17:28:18 2017 utc. This means that Ubuntu 4.4.0-97-generic has been compiled 120 times. The timestamp of the last compilation is also available.
- x86_64 is a machine architecture.
- x86_64 – processor architecture.
- x86_64 – architecture of the operating system (you can use 32-bit – run the operating system on a 64-bit processor). “
- operating systemThe gnu / linux theme (and no, the distribution name is not displayed).
But I will save you information overload. Let’s take a look at some other commands to find out your Linux kernel version.
2. Find The Linux Kernel Using The File / Proc / Version
On Linux, users can also find kernel instructions in the / proc / version file. Just look at the contents of this skill file:
cat / proc / version You will see a result similar to uname.

dmesg is a command commonly used to write kernel messages. It’s all too helpful to have a manual system.
Since dmesg contains a lot of information, you should usually use a great command, such as reading less about the concept. But since we’re only here to check the Linux kernel version, after typing “Linux” it should give a specific result.
dmesg | grep Linux The output will certainly consist of several sstring, but your organization should be able to easily identify the Linux kernel version in it.
