You're using Linux 🐧wrong!

Most people dive into Linux without truly understanding its file system hierarchy, leading to confusion and inefficiency.

Ever wondered why system files are scattered across /bin, /sbin, and /usr/bin? Or why logs are in /var/log instead of /log?

Here’s a breakdown of the Linux File System Hierarchy to clear up the confusion:

╰ / - Root directory (everything starts here)
╰ /bin - Essential binaries (ls, cp, mv)
╰ /boot - Boot loader files (kernel, GRUB)
╰ /dev - Device files (USB, HDD, tty)
╰ /etc - Configuration files
╰ /home - User home directories
╰ /lib - Essential system libraries
╰ /media - Auto-mounted media (USB, CD)
╰ /mnt - Temporary mount point
╰ /opt - Third-party software packages
╰ /proc - Virtual filesystem for processes
╰ /root - Root user’s home directory
╰ /run - Runtime process data
╰ /sbin - System binaries (fsck, reboot)
╰ /srv - Server-specific data
╰ /sys - Kernel system information
╰ /tmp - Temporary files (cleared on reboot)
╰ /usr - User applications and tools
╰ /usr/bin - Non-essential user binaries
╰ /usr/lib - Libraries for /usr/bin
╰ /usr/local - Locally installed software
╰ /usr/share - Shared data (icons, docs)
╰ /var - Variable data (logs, cache, mail)
╰ /var/log - System logs
╰ /var/spool - Queued jobs (print, mail)

Understanding this structure helps you -

🔠 Locate files efficiently
🔠 Troubleshoot system issues faster
🔠 Optimize performance & security

🔜 Many Cloud Engineers don’t fully understand API Gateway vs Load Balancer implications. 🔙

➡️ API Gateway focuses on managing how clients access services.

➡️ Load Balancer handles where the traffic goes.
