Read several times, until it sinks :-) Once you can answer questions like - what happens if you hardlink a file "foo" to a new name "bar", and then delete "foo"? - what happens in the above scenario if you instead do a softlink? - why can't you hardlink across file system boundaries? what about a soft link? - what happens if you hardlink "foo" to "bar" and then change "bar"'s permissions? Once you have the relationships between file, inode and directory entry straight in your head, the rest is comparatively easy: - https://en.wikipedia.org/wiki/Unix_filesystem - https://en.wikipedia.org/wiki/File_system_permissions And yes, a man page is a manual, not a text book. So it's as it is supposed to be :-) A good introductory text (it's a bit old, the implementation details have changed a lot since, but it'll give you a good foundation) is Maurice Bach's "The design of the UNIX operating system": https://archive.org/details/DesignOfTheUnixOperatingSystemByMauriceBach oh, and leave a tip to the great folks at the Internet archive on your way out.
