Name
       chgrp - change file group

Syntax
       chgrp [ -fR ] group file...

Description
       The command changes the group ID of one or more files or directories.  For file, you may specify either a full or partial path.	For group,
       you may specify either a decimal GID or a group name found in the group file.

       The user entering the command must either be the superuser, or be the owner of the file and belong to the specified group.

Options
       -f   Inhibits display of errors that are returned if fails to change the group identifier of a file.

       -R   Causes to recursively descend any directories subordinate to file and to set the specified	group for  each  file  encountered.   When
	    symbolic links are encountered, changes the group identifier of the link file but does not traverse the path associated with the link.
