LINUX FILE SYSTEM HIERARCHY (FHS – /, /home, /etc, /var, /usr) The Linux File System Hierarchy Standard (FHS) defines how directories are structured → ensures consistency across Linux distributions → makes system navigation predictable for users and developers ROOT DIRECTORY (/) / → top-level directory of the entire file system → everything starts here Contains → all other directories and files → mounted devices and partitions HOME DIRECTORY (/home) /home → stores user personal data Structure → /home/user1 → /home/user2 Contains → documents → downloads → configurations (user-level) Purpose → separates user data from system files → safe for backups and restores CONFIGURATION DIRECTORY (/etc) /etc → system-wide configuration files Contains → system settings → service configurations → startup scripts Examples → /etc/passwd → user account info → /etc/hosts → hostname mappings → /etc/nginx → server configs Purpose → central place for configuration → easy system management VARIABLE DATA DIRECTORY (/var) /var → variable and frequently changing data Contains → logs → caches → spool files → databases Examples → /var/log → system logs → /var/cache → cached data → /var/lib → application state Purpose → stores dynamic system data → grows over time USER PROGRAMS DIRECTORY (/usr) /usr → user utilities and applications Contains → binaries → libraries → documentation Structure → /usr/bin → user commands → /usr/lib → libraries → /usr/share → shared resources Purpose → read-only user programs → shared across system HOW THEY WORK TOGETHER System Boot → kernel mounts root (/) System Services → read configs from /etc User Logs In → accesses files in /home Applications Run → binaries from /usr System Activity → logs stored in /var KEY DESIGN PRINCIPLES Separation of Concerns → system files vs user data Consistency → same structure across distributions Scalability → supports small systems to enterprise servers Security → controlled access to critical directories SIMPLE FLOW EXAMPLE User Command → executed from /usr/bin Configuration → read from /etc User Data → accessed in /home Logs → written to /var/log SUMMARY / → root of everything /home → user data /etc → configuration /var → dynamic data /usr → applications and libraries Together → form a structured, predictable, and scalable Linux file system For a complete deep dive into Linux, system internals, and real-world engineering → get the Linux Mastery Ebook: codewithdhanian.gumroad.com/l/dynwdc
