NAME
       ln  -  make a link

SYNOPSIS
       ln name1 [ name2 ]

DESCRIPTION
       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.
