unlink(1M)

NAME

     link, unlink - link and unlink files and directories

SYNOPSIS

     /usr/sbin/link  existing-file new-file

     /usr/xpg4/bin/link  existing-file new-file

     /usr/sbin/unlink  file

DESCRIPTION

     The link and unlink  commands  link  and  unlink  files  and
     directories.  Only  super-users  can  use  these commands on
     directories.

     Use link to create a new file that  points  to  an  existing
     file. The  existing-file and  new-file operands  specify the
     existing file and newly-created files.  See OPERANDS.

     link and  unlink directly invoke the link(2)  and  unlink(2)
     system  calls,  performing  exactly what they are told to do
     and abandoning all error checking.  This  differs  from  the
     ln(1) command. See  ln(1).

     While linked files and  directories  can  be  removed  using
     unlink,  it  is safer to use rm(1) and rmdir(1) instead. See
     rm(1) and  rmdir(1).

  /usr/xpg4/bin/link
     If the existing file being hard linked is itself a  symbolic
     link,  then the newly created file (new-file) will be a hard
     link to the file referenced by the symbolic link, not to the
     symbolic link object itself (existing-file).

OPERANDS

     The following operands are supported:

     existing-file
           Specifies the name of the existing file to be linked.

     file  Specifies the name of the file to be unlinked.

     new-file
           Specifies the name of newly created (linked) file.

     See  environ(5) for descriptions of the  following  environ-
