chgrp

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

Change the group of each FILE to GROUP.

Options

--help

Print help information.

--changes, -c

like verbose but report only when a change is made

--silent, -f

--quiet

suppress most error messages

--verbose, -v

output a diagnostic for every file processed

--preserve-root

fail to operate recursively on ‘/’

--no-preserve-root

do not treat ‘/’ specially (the default)

--reference=<RFILE>

use RFILE’s group rather than specifying GROUP values

--from=<GROUP>

change the group only if its current group matches GROUP

--recursive, -R

operate on files and directories recursively

-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)

--dereference

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

--no-dereference, -h

affect symbolic links instead of any referenced file (useful only on systems that can change the ownership of a symlink)

Examples

Change the owner group of a file/directory:

chgrp {{group}} {{path/to/file_or_directory}}

Recursively change the owner group of a directory and its contents:

chgrp {{[-R|--recursive]}} {{group}} {{path/to/directory}}

Change the owner group of a symbolic link:

chgrp {{[-h|--no-dereference]}} {{group}} {{path/to/symlink}}

Change the owner group of a file/directory to match a reference file:

chgrp --reference {{path/to/reference_file}} {{path/to/file_or_directory}}
