NAME
     ln	-- make	links

SYNOPSIS
     ln	[-fs] source_file [target_file]
     ln	[-fs] source_file ... [target_dir]

DESCRIPTION
     The ln utility creates a new directory entry (linked file)	which has the
     same modes	as the original	file.  It is useful for	maintaining multiple
     copies of a file in many places at	once without using up storage for the
     "copies"; instead,	a link "points"	to the original	copy.  There are two
     types of links; hard links	and symbolic links.  How a link	"points" to a
     file is one of the	differences between a hard or symbolic link.

     The options are as	follows:

     -f	   Unlink any already existing file, permitting	the link to occur.

     -s	   Create a symbolic link.

     By	default	ln makes hard links.  A	hard link to a file is indistinguish-
     able from the original directory entry; any changes to a file are effec-
     tive independent of the name used to reference the	file.  Hard links may
     not normally refer	to directories and may not span	file systems.

     A symbolic	link contains the name of the file to which it is linked.  The
     referenced	file is	used when an open(2) operation is performed on the
     link.  A stat(2) on a symbolic link will return the linked-to file; an
     lstat(2) must be done to obtain information about the link.  The
     readlink(2) call may be used to read the contents of a symbolic link.
     Symbolic links may	span file systems and may refer	to directories.

     Given one or two arguments, ln creates a link to an existing file
     source_file.  If target_file is given, the	link has that name;
     target_file may also be a directory in which to place the link; otherwise
     it	is placed in the current directory.  If	only the directory is speci-
     fied, the link will be made to the	last component of source_file.

     Given more	than two arguments, ln makes links in target_dir to all	the
     named source files.  The links made will have the same name as the	files
     being linked to.
