If you're an IT professional, navigating the Linux file system is a skill that can take you far.
The Linux file system hierarchy is a tree-like structure that organizes all of the files and directories on a Linux system.
It is a logical organization of the file system, and it is not necessarily the same as the physical organization of the files on the disk.
The root directory of the Linux file system is /. All other directories and files are contained
Let's dive into the core directories that make up the Linux file system:
1. /𝗯𝗶𝗻 🛠️: Houses essential system binaries like the 𝚋𝚊𝚜𝚑 shell, 𝚕𝚜, and 𝚐𝚛𝚎𝚙.
2. /𝗯𝗼𝗼𝘁 🚀: Contains boot essentials like the kernel image and bootloader.
3. /𝗱𝗲𝘃 🔌: A hub for device files representing connected hardware.
4. /𝗲𝘁𝗰 📜: The home for Linux system configuration files.
5. /𝗵𝗼𝗺𝗲 🏠: User home directories reside here.
6. /𝗹𝗶𝗯 📚: Contains shared libraries used across various programs.
7. /𝗺𝗲𝗱𝗶𝗮 💿: Mount points for removable media like CDs and USB drives.
8. /𝗺𝗻𝘁 🧲: For temporary filesystem mounts.
9. /𝗼𝗽𝘁 📦: Houses optional software packages.
10. /𝗽𝗿𝗼𝗰 📊: Information central for the running system, processes, and memory usage.
11. /𝗿𝗼𝗼𝘁 👑: The home directory for the root user.
12. /𝘀𝗯𝗶𝗻 🔧: Contains system admin binaries like 𝚒𝚗𝚒𝚝 and 𝚏𝚍𝚒𝚜𝚔.
13. /𝘀𝗿𝘃 🌐: Data storage for services like web servers.
14. /𝘁𝗺𝗽 🌡️: A space for temporary files.
15. /𝘂𝘀𝗿 🖥️: Most user-installed software finds its place here.
16. /𝘃𝗮𝗿 🔄: Holds variable data, including logs and temporary files.
