     chown -- change file owner	and group

     chown [-R [-H | -L	| -P]] [-f] [-h] owner [:group]	file ...
     chown [-R [-H | -L	| -P]] [-f] [-h] :group	file ...

     Chown sets	the user ID and/or the group ID	of the specified files.

     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.

     -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 mod-
	     ify 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 rather	than the file that the link
	     points to.

     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 specified.

     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.

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

     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.

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

     The chown command is expected to be IEEE Std 1003.2 ("POSIX.2") compli-

     A chown command appeared in Version 1 AT&T	UNIX.
