12.1 `link': Make a hard link via the link syscall
`link' creates a single hard link at a time.  It is a minimalist
interface to the system-provided `link' function.  *Note Hard Links:
(libc)Hard Links.  It avoids the bells and whistles of the more
commonly-used `ln' command (*note ln invocation::).  Synopsis:
   FILENAME must specify an existing file, and LINKNAME must specify a
nonexistent entry in an existing directory.  `link' simply calls `link
(FILENAME, LINKNAME)' to create the link.
   On a GNU system, this command acts like `ln --directory
--no-target-directory FILENAME LINKNAME'.  However, the `--directory'
and `--no-target-directory' options are not specified by POSIX, and the
`link' command is more portable in practice.
   If FILENAME is a symbolic link, it is unspecified whether LINKNAME
will be a hard link to the symbolic link or to the target of the
symbolic link.  Use `ln -P' or `ln -L' to specify which behavior is
   An exit status of zero indicates success, and a nonzero value
indicates failure.
