NAME

chgrp - change group ownership

SYNOPSIS

chgrp [ OPTION ]... GROUP FILE ...
chgrp [ OPTION ]... --reference=RFILE FILE ...

DESCRIPTION

Change the group of each FILE to GROUP. With --reference , change the group of each FILE to that 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

--dereference

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)

--from = CURRENT_OWNER :CURRENT_GROUP

change the ownership 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 attribute

--no-preserve-root

do not treat ’/’ specially (the default)

--preserve-root

fail to operate recursively on ’/’

--reference = RFILE

use RFILE’s ownership rather than specifying values. RFILE is always dereferenced if a symbolic link.

-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 final one takes effect. -P is the default.

	-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
	--help		display this help and exit

--version

output version information and exit

EXAMPLES

chgrp staff /u

Change the group of /u to "staff".

chgrp -hR staff /u

Change the group of /u and subfiles to "staff".
