Proc File System in Linux – An Overview

The Proc File System (procfs) in Linux is an innovative, virtual file system located in memory. It serves as a live interface to the kernel’s internal data structures. Instead of keeping data on disk, “files” within procfs are created in real time as they are accessed, providing up-to-date information about the system’s processes, hardware, and overall configuration.

Proc File System in Linux – Complete View

It serves as a valuable resource, providing information about currently running processes, and as a hub for controlling and relaying information to the kernel. Additionally, the proc file system facilitates communication between kernel space and user space.

I’d like to share an interesting finding with you today. Perhaps, many of you must be already familiar with it but being a newbie, it really intrigued me. Continue reading “Proc File System in Linux – An Overview”
