NAME
     chown -- change file owner and group

SYNOPSIS
     chown [-fhv] [-R [-H | -L | -P]] owner[:group] file ...
     chown [-fhv] [-R [-H | -L | -P]] :group file ...

DESCRIPTION
     The chown utility changes the user ID and/or the group ID of the specified files.	Symbolic
     links named by arguments are silently left unchanged unless -h is used.

     The options are as follows:

     -H      If the -R option is specified, symbolic links on the command line are followed.
	     (Symbolic links encountered in the tree traversal are not followed.)

     -L      If the -R option is specified, all symbolic links are followed.

     -P      If the -R option is specified, no symbolic links are followed.  This is the default.

     -R      Change the user ID and/or the group ID for the file hierarchies rooted in the files
	     instead of just the files themselves.

     -f      Don't report any failure to change file owner or group, nor modify the exit status
	     to reflect such failures.

     -h      If the file is a symbolic link, change the user ID and/or the group ID of the link
	     itself.

     -v      Cause chown to be verbose, showing files as the owner is modified.

     The -H, -L and -P options are ignored unless the -R option is specified.  In addition, these
     options override each other and the command's actions are determined by the last one speci-
     fied.

     The owner and group operands are both optional, however, one must be specified.  If the
     group operand is specified, it must be preceded by a colon (``:'') character.

     The owner may be either a numeric user ID or a user name.	If a user name is also a numeric
     user ID, the operand is used as a user name.  The group may be either a numeric group ID or
     a group name.  If a group name is also a numeric group ID, the operand is used as a group
     name.

     The ownership of a file may only be altered by a super-user for obvious security reasons.

DIAGNOSTICS
     The chown utility exits 0 on success, and >0 if an error occurs.

COMPATIBILITY
     Previous versions of the chown utility used the dot (``.'') character to distinguish the
     group name.  This has been changed to be a colon (``:'') character so that user and group
     names may contain the dot character.

     On previous versions of this system, symbolic links did not have owners.

     The -v option is non-standard and its use in scripts is not recommended.

SEE ALSO
     chgrp(1), find(1), chown(2), fts(3), symlink(7)

STANDARDS
     The chown utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compliant.

HISTORY
     A chown utility appeared in Version 1 AT&T UNIX.
