  chown	- Changes the owner of files or	directories


  chown	[-fhR] owner [:group] file...

  The chown command changes the	owner of the specified files or	directories
  to the specified user	name or	user ID.


  Interfaces documented	on this	reference page conform to industry standards
  as follows:

  chown:  XCU5.0

  Refer	to the standards(5) reference page for more information	about indus-
  try standards	and associated tags.


  -f  [Tru64 UNIX]  Turns off error reporting.

  -h  [Tru64 UNIX]  If file is a symbolic link,	chown -h file changes the
      owner of the symbolic link. The chown file format	changes	the owner of
      the file referenced by the symbolic link.

  -R  Descends recursively through its directory arguments, setting the
      specified	owner.


      The pathname of the file for which ownership is to be changed.

      A	user ID	and optional group ID to be assigned to	file. The owner	por-
      tion of this operand must	be a user name from the	user database or a
      numeric user ID. Either specifies	a user ID to be	given to each file
      named by one of the file operands. If a numeric owner operand exists in
      the user database	as a user name,	the user ID number associated with
      that user	name will be used as the user ID.

      If the group portion of this operand is present, it must be a group
      name from	the group database or a	numeric	group ID. Either specifies a
      group ID to be given to each file. If a numeric group operand exists in
      the group	database as a group name, the group ID number associated with
      that group name will be used as the group	ID.


  [Tru64 UNIX]	Only a user with superuser authority can use the chown com-

  The owner argument must be a valid user name or a valid numerical user ID.
  The optional group argument must be a	valid group name or a valid numerical
  group	ID.


  The following	exit values are	returned:

  0   The chown	command	executed successfully and all requested	changes	have
      been made.

  >>0  An error occurred.


  To change the	owner of the file program.c, enter:

       chown  steffan  program.c

  The user access permissions for program.c now	apply to steffan.  As the
  owner, steffan can use the chmod command to permit or	deny the other users
  access to program.c. See the chmod command for details.


  The following	environment variables affect the execution of chown:

      Provides a default value for the internationalization variables that
      are unset	or null. If LANG is unset or null, the corresponding value
      from the default locale is used.	If any of the internationalization
      variables	contain	an invalid setting, the	utility	behaves	as if none of
      the variables had	been defined.

      If set to	a non-empty string value, overrides the	values of all the
      other internationalization variables.

      Determines the locale for	the interpretation of sequences	of bytes of
      text data	as characters (for example, single-byte	as opposed to multi-
      byte characters in arguments).

      Determines the locale for	the format and contents	of diagnostic mes-
      sages written to standard	error.

      Determines the location of message catalogues for	the processing of
