 **kmon** provides a [text-based user interface](https://en.wikipedia.org/wiki/Text-based_user_interface) for managing the Linux kernel modules and monitoring the kernel activities. By managing, it means loading, unloading, blacklisting and showing the information of a module. These updates in the kernel modules, logs about the hardware and other kernel messages can be tracked with the real-time activity monitor in kmon. Since the usage of different tools like [dmesg](https://en.wikipedia.org/wiki/Dmesg) and [kmod](https://www.linux.org/docs/man8/kmod.html) are required for these tasks in Linux, kmon aims to gather them in a single terminal window and facilitate the usage as much as possible while keeping the functionality.
