     ln	-- make	links

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

     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 and 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-
     tively 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.

     link(2), lstat(2),	readlink(2), stat(2), symlink(2), symlink(7)

     An	ln command appeared in Version 1 AT&T UNIX.
