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  informa-
     tion, etc) may have several links to it.  There is no way to
     distinguish a link to a file from its original directory en-
     try;  any changes in the file are effective 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.

SEE ALSO
     rm(I)

BUGS
     There is nothing particularly wrong with ln, but tp  doesn't
     understand  about  links and makes one copy for each name by
     which a file is known; thus if the tape is extracted several
     copies  are restored and the information that links were in-
     volved is lost.
