virtual filesystems

In the vast expanse of Linux functionalities, two special filesystems stand out for their unique roles in system management and configuration: /proc and /sys. These filesystems don't exist on your disk like typical filesystems. Instead, they exist solely in memory, and they provide a dynamic interface into the kernel. They allow users and applications to peek into the kernel's internals and even change certain settings at runtime. In this article, we'll dive deep into what these virtual filesystems are, how they function, and the kind of information and control they offer to users. The /proc filesystem is a pseudo-filesystem which means it does not exist in real physical storage.
