About the course

This course teaches students how Linux file systems and permissions really work beneath the surface. You will learn how files are organized, how paths and directories function, what inodes are, how links work, and how Linux decides who can read, write, or execute files. The course is built to turn confusing permission errors and file system concepts into something clear, practical, and easy to apply.
