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.


     Note that the ZFS file system does not support links between
     directories.


     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.

Environment Variables

     variables  that  affect the execution of link: LANG, LC_ALL,
     LC_CTYPE, LC_MESSAGES, and NLSPATH.
