Understanding the Linux File System: A Beginner's Guide

Navigating the Linux file system can seem daunting at first, but it's actually quite organized! Unlike Windows, Linux uses a single-rooted hierarchy, making it easier to manage once you understand the key directories.

This post provides a quick overview of the most important directories defined by the Filesystem Hierarchy Standard (FHS):

  • /: The root directory - the starting point for everything.

  • /bin: Essential commands everyone uses (like ls, cp).

  • /sbin: System admin commands (require root privileges).

  • /etc: Configuration files for the whole system.

  • /home: Where user's personal files live.

  • /var: Files that change frequently (logs, etc.).

  • /tmp: Temporary files.

  • /usr: User applications and libraries.

  • /lib: System libraries.

  • /opt: Optional software.

  • /mnt & /media: For mounting drives and devices.

  • /dev: Files that represent hardware.

  • /proc & /sys: Information about the kernel and processes.
