kernelversion

Additional Notes

kernelversion is a simple utility that prints the version string of the currently running Linux kernel. It extracts the version from the /proc/sys/kernel/osrelease file or similar system interfaces.

It provides a quick way to check the kernel version in scripts or automation without parsing /proc/version or using uname -r.

Syntax

kernelversion

The command takes no options or arguments. It simply prints the kernel version to stdout.

Parameters

• options: Flags that change how kernelversion behaves.
• target: Optional file, device, interface, user, service, or command target when the command supports one.

Examples

kernelversion

Output example: 6.8.0-arch1-1

kernelversion | cut -d. -f1

Extract the major version number.

Practical Notes

• uname -r is a more widely available alternative that works on all POSIX systems.
• This command may not be installed by default on all distributions.
