hard link review

All files in *nix reside in inodes
File names are “links” to the inodes
You can have multiple links (filenames) referring to the same file, called a “hard link”
Note effect of changes in contents, permissions, ownership
A file is not deleted until all of its links are removed (rm removes a link, not a file).
Multiple hard links to the same file only works on the same filesystem
