NAME
       chown - Changes the owner of files or directories

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

       The  chown command changes the owner of the specified files or directo‐
       ries to the specified user name or user ID.

STANDARDS
       Interfaces documented on this reference page conform to industry	 stan‐
       dards as follows:

       chown:  XCU5.0

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

OPTIONS
       [Tru64 UNIX]  Turns off error reporting.	 [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.	 Descends recursively through its directory arguments,
       setting the specified owner.

OPERANDS
       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 portion 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.

DESCRIPTION
       [Tru64  UNIX]  Only  a  user with superuser authority can use the chown
       command.

       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.

EXIT STATUS
       The following exit values are returned: The chown command executed suc‐
       cessfully and all requested changes have been made.  An error occurred.

EXAMPLES
       To  change the owner of the file program.c, enter: chown	 steffan  pro‐
       gram.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.

ENVIRONMENT VARIABLES
       The following environment variables affect the execution of chown: Pro‐
       vides  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 vari‐
       ables contain an invalid setting, the utility behaves as if none of the
       variables  had been defined.  If set to a non-empty string value, over‐
       rides 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 messages written to standard error.	Deter‐
       mines  the location of message catalogues for the processing of LC_MES‐
       SAGES.

FILES
       Contains user names and numeric user IDs.
