How do I know about the Linux kernel version I am using? How do I check the Linux distribution name? How can I see the Linux kernel version number?

    Many times, you might have required to know about some details about your Linux system, such as name of the kernel, its version, host name and many more. No doubt you can get these details in the corresponding files residing in the proc directory, but uname command makes the things more convenient and quicker. uname can provide you a lot of information about your Linux system.

    Before we move to tutorial part of uname command, just remember the syntax of this command:

uname [OPTION]

Basic Use of uname Command

1. Know the Name of Your Kernel

Simplest use of any command is when it is used without any option. When uname command is used with no option, it displays the name of the kernel present in your system.

Usage: uname

You may also use the option –s to know the kernel name.

Usage: uname –s

Output:
uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux,

The /proc Directory

We have read about this directory in our previous article Know About Important Directories in Linux and Their Usage.

The /proc/version file will show you the version of the kernel the system is running. Open this file using cat command and see its contents. (Know more about cat command in this article)

Output:
uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux,


Now, run the following command and compare its output with the above output.

cat /proc/sys/kernel/{ostype,osrelease,version}

Output: 
uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux, uname-command-in-linux,


The conclusion is, the output of the command cat /proc/version contains the contents of /proc/sys/kernel/ostype, /proc/sys/kernel/osrelease, and /proc/sys/kernel/version files.

That’s all. I have tried to cover basic use of uname command to observe the information related to your system. If you like this article then share it as much as possible, for any feedback use the comment section below and please stay tuned for some more interesting articles.
