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)

−−no−preserve−root

do not treat '/' specially (the default)

−−preserve−root

fail to operate recursively on '/'

−−reference=RFILE/

use RFILE's group rather than specifying a GROUP value

−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.

−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

−−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".
