link(1M)

NAME
     link, unlink - link and unlink files

SYNOPSIS
     link file1 file2
     unlink file

DESCRIPTION
     The link command is used to create a filename that points to another
     file.  The unlink command is used to remove a link to a file.

     The only difference between ln(1) and link(1M) is that the latter simply
     makes the link(2) system call with the arguments specified.  No error
     checking is performed.  Analogously, unlink(1M) simply calls the
     unlink(2) system call with the specified pathname.

     Use of these commands is discouraged.  The commands ln(1), rm(1), and
     rmdir(1) provide the necessary functionality in a safer manner.
