What is a "/proc" file system?
A “/proc” file system is a special type of file system that has special access permissions. It is mounted in Linux systems when the kernel needs to execute a process or access certain system resources.
A /proc directory contains information about the current state of the system, such as memory usage and CPU speed.
There are three subdirectories under /proc :
/proc/1 : This is the first subdirectory in the /proc directory tree. It contains information about the CPU and its speed.
/proc/1/cmdline : This subdirectory contains the command line parameters passed to the currently running process.
/proc/1/maps : This subdirectory contains virtual memory map data for processes running on Linux systems. It can be used to determine which parts of the memory are being used by which process.
