Linux Filesystems
Learn Linux filesystems through paths, file types, mounts, links, ownership, permissions, capacity, inodes, and safe storage investigation.
PRACTICAL TOPIC GUIDE
What this topic prepares you to do
The Linux filesystem presents devices, configuration, application data, logs, and user files through one directory tree. This topic explains absolute and relative paths, common filesystem locations, file types, links, mount points, ownership, permissions, space usage, and inode limits as parts of that model.
Commands are used to answer precise questions: which filesystem contains a path, what is mounted there, who owns an object, which permission applies, where capacity is consumed, and whether deleted-but-open files or exhausted inodes explain a discrepancy. Destructive cleanup is never the first diagnostic step.
