ln — Make LiNks between files.
Create a link to the specified TARGET with optional LINK_NAME. If LINK_NAME is omitted, a link with the same basename as the TARGET is created in the current directory. By default, it makes HardLinks.
A “hard link” is another name for an existing file. The link and the original are indistinguishable. They share the same inode.
A Soft links/Symbolic links/symlinks are a special file type. The link file actually refers to a different file, by name. At runtime kernel automatically “dereferences” the link and operates on the target of
