The linked file contains the pathname of the original file, hence it is called a symbolic link. The linked file is dependent on the original file, so if that is deleted, the linked file or directory will no longer work. When running an ls -l command in a directory which contains symbolic link files, you get a different output to usual.

Finally, the name of the link file is followed by an arrow to the full pathname of the original file.
When making a hard link of a file, the same file is given two different names. Once a link is created, it is indistinguishable from the original directory entry. However, these files must be in the same file system, meaning within the same 'branch' from the root directory. i.e. If the first file is underneath /u
