Understanding the Linux File System Hierarchy: A Brief Overview

Linux organizes its files and directories in a hierarchical structure, starting from the root directory "/"

The root directory is the top-level directory in the hierarchy, and all other directories and files are stored within it

[{"selector":"#anim-efa68f39-e63f-4c00-a69c-7e84b35d656d [data-leaf-element=\"true\"]","keyframes":{"transform":["translate(0%, 0%) scale(1.5)","translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}] [{"selector":"#anim-8ad2b2e9-5377-46f5-abc5-cf5889ae4186","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}]

The "/bin" directory contains essential system binaries that are used by all users as "ls", "cat", "mv" and "cp"

[{"selector":"#anim-53e3c2b4-5f85-4050-a448-985be771e48c [data-leaf-element=\"true\"]","keyframes":{"transform":["translate(0%, 0%) scale(1.5)","translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}] [{"selector":"#anim-0e240d56-4c82-450a-9699-8fb92e816133","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}]

The "/sbin" directory contains system binaries that are used by the root user
