System Administration Commands                                        link(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  directo-
       ries.


       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 ref-
       erenced 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 environment variables
       that affect the execution of link: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES,
