ln - make a link
ln name1 [ name2 ]
A link is a directory entry referring to a file; the same file (together with its size, all its protection information, etc.) may have
several links to it. There is no way to distinguish a link to a file from its original directory entry; any changes in the file are effec-
tive independently of the name by which the file is known.
Ln creates a link to an existing file name1. If name2 is given, the link has that name; otherwise it is placed in the current directory
and its name is the last component of name1.
It is forbidden to link to a directory or to link across file systems.
