Certified: The CompTIA Linux+ Audio Course

The Filesystem Hierarchy Standard (FHS) shows up on Linux+ because “where” is often the clue to “what,” especially when questions compress a scenario into a few paths and log snippets. This episode teaches the FHS as a practical map of intent: binaries that run the system, configuration that defines behavior, variable data that changes during runtime, and user data that should be protected and backed up differently. You’ll connect common exam prompts to the right directories so you can reason quickly under time pressure, such as recognizing why a config change belongs in /etc rather than a random home directory, or why troubleshooting often starts with logs in /var. The goal is not memorizing every path, but learning the small set of high-frequency locations that drive most admin decisions.

You’ll work through scenarios like “disk full” conditions caused by runaway logs under /var, services failing because a file in /etc is malformed, or software installs putting artifacts in unexpected locations that complicate upgrades and removals. We also address why FHS knowledge helps with permissions and security questions: putting secrets in the wrong directory changes who can read them, and mixing variable data into static locations creates drift that breaks predictability. Finally, you’ll learn a verification mindset: when you suspect a path, confirm ownership, permissions, and whether the data is meant to be persistent or regenerated, so you choose fixes that survive reboot and upgrades.
