on Unix systems, the actual 'file' is known as an inode, and is
identified by a inode number. Directories are other files that contain
indexed directory entries with filenames pointing to these inodes.
the tricky thing with hard links is, you have to walk the whole
directory tree of a given file system to find every entry pointing to
the same inode if you want to identify these links.
