chgrp command

On Unix-like operating systems, the chgrp command changes the group ownership of a file or files.

This document covers the GNU/Linux version of chgrp.


The chgrp command changes the group of each FILE to GROUP. If the --reference option is specified, chgrp changes the group of each FILE to that of RFILE.


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


-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 referenced file of each symbolic link, rather than the symbolic link itself, which is default setting.

-h, --no-dereference

Affect symbolic links instead of any referenced file. This option is useful only on systems that can change the ownership of a symlink.


Do not treat '/' in any special way. This option is the default.


Do not operate recursively on '/'.


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 of these options is specified, only the final one takes effect:


If a command line argument is a symbolic link to a directory, traverse it.


Traverse every symbolic link to a directory.


Do not traverse any symbolic links. This option is the default.


Display a help message and exit.


Output version information and exit.


chgrp hope file.txt

Change the owning group of the file file.txt to the group named hope.

chgrp -hR staff /office/files

Change the owning group of /office/files, and all subdirectories, to the group staff.
