Linux File System Hierarchy Standard (FHS) Overview
The base and starting point of the entire file system hierarchy.
Essential command binaries available to all users (e.g., `ls`, `cp`).
System administration binaries, typically run by the root user (e.g., `shutdown`).
System-wide configuration files (e.g., `passwd`, network settings).
Shared libraries needed by the essential programs in /bin and /sbin.
User home directories for personal files and configurations.
Unix System Resources: contains most user-related programs and libraries (e.g., /usr/bin).
Variable data that changes frequently, such as system and application log files.
Optional add-on application software from third-party vendors.
Virtual file system providing process and kernel information.
Exposes kernel objects and configuration for devices.
Temporary files (often cleared on reboot).
Mount points for external filesystems (disks, USB drives).
