       chown - change file owner and group

       chown [OPTION]... [OWNER][:[GROUP]] FILE...
       chown [OPTION]... --reference=RFILE FILE...

       This manual page	documents the GNU version of chown.  chown changes the
       user and/or group ownership of each given file.	If only	 an  owner  (a
       user  name or numeric user ID) is given,	that user is made the owner of
       each given file,	and the	files' group is	not changed.  If the owner  is
       followed	 by  a	colon  and a group name	(or numeric group ID), with no
       spaces between them, the	group ownership	of the	files  is  changed  as
       well.  If a colon but no	group name follows the user name, that user is
       made the	owner of the files and the group of the	files  is  changed  to
       that  user's  login  group.   If	the colon and group are	given, but the
       owner is	omitted, only the group	of the files is	changed; in this case,
       chown  performs	the same function as chgrp.  If	only a colon is	given,
       or if the entire	operand	is empty, neither the owner nor	the  group  is

       Change the owner	and/or group of	each FILE to OWNER and/or GROUP.  With
       --reference, change the owner and group of each FILE to those of	RFILE.

       -c, --changes
	      like verbose but report only when	a change is made

       -f, --silent, --quiet
	      suppress most error messages

       -v, --verbose
	      output a diagnostic for every file processed

	      affect the referent of each symbolic link	(this is the default),
	      rather than the symbolic link itself

       -h, --no-dereference
	      affect  symbolic	links  instead	of any referenced file (useful
	      only on systems that can change the ownership of a symlink)

	      change the owner and/or group of each file only if  its  current
	      owner  and/or  group  match those	specified here.	 Either	may be
	      omitted, in which	case a match is	not required for  the  omitted

	      do not treat '/' specially (the default)

	      fail to operate recursively on '/'

	      use  RFILE's  owner and group rather than	specifying OWNER:GROUP

       -R, --recursive
	      operate on files and directories recursively

       The following options modify how	a hierarchy is traversed when  the  -R
       option  is also specified.  If more than	one is specified, only the fi-
       nal one takes effect.

       -H     if a command line	argument is a symbolic link  to	 a  directory,
	      traverse it

       -L     traverse every symbolic link to a	directory encountered

       -P     do not traverse any symbolic links (default)

       --help display this help	and exit

	      output version information and exit

       Owner  is  unchanged  if	 missing.   Group is unchanged if missing, but
       changed to login	group if implied by a ':' following a symbolic	OWNER.
       OWNER and GROUP may be numeric as well as symbolic.

       chown root /u
	      Change the owner of /u to	"root".

       chown root:staff	/u
	      Likewise,	but also change	its group to "staff".

       chown -hR root /u
	      Change the owner of /u and subfiles to "root".
