What can be found in the /proc/ directory of a Linux system?

The /proc/ directory serves as a virtual filesystem that provides a wealth of information about system processes and other kernel parameters. One of its key features is the representation of each running process in the system. Within /proc/, you will find a subdirectory for each active process, labeled with its corresponding process ID (PID). These directories contain various files that offer insights into the process's status, memory usage, file descriptors, and more, allowing users and system administrators to monitor and manage processes effectively.

This structure is integral to understanding how process management works in Linux, as it allows for real-time access to process information without needing to use additional tools or commands. Each directory under /proc/ behaves like a file system node and can be used to read or write information, contributing to dynamic interaction with the Linux kernel.
