rmmod

Linux kernel modules are pieces of code that can be loaded and unloaded into the kernel upon demand. They extend the functionality of the kernel without the need for rebooting the system. In this article, we'll explore how to manage these modules using modprobe and rmmod commands. Q: What is a kernel module? A: A kernel module is a program that can be loaded into or unloaded from the kernel upon demand, without necessarily rebooting the system. These modules can provide additional capabilities or functions to the base Linux kernel. Q: What is modprobe? A: modprobe is a command-line utility that allows users to load a module or set of modules into the kernel.

Linux kernel modules are essential to the operating system, enabling it to efficiently run hardware and software alike. By dynamically loading and unloading these modules, users can optimise system performance without needing to reboot. In this blog, we will delve into what kernel modules are, why they matter, how to load and unload them, and operational instructions for managing them through different Linux package managers, namely apt (used by Debian-based distributions like Ubuntu), dnf (used by Fedora), and zypper (used by openSUSE). Kernel modules are pieces of code that can be loaded into the Linux kernel as needed. They extend the kernel's capabilities without having to permanently alter the kernel structure.
