In this article and related video, we will be discussing how to check the kernel version in both Ubuntu and CentOS Linux.

Here’s the code to run from the command line:
You should receive a result similar to the following:
|The kernel version output from above
can be interpreted with the following key:
|2||=||The Main Kernel Version|
|6||=||The Major Revision|
|32||=||The Minor Revision|
|431.11.2.el6||=||The Minor Fix/Revision Detail|
