DESCRIPTION

chgrp sets the group ID to group for the files and directories named by the pathname arguments. group may be a group name from the group database, or a numeric group ID.

Options

-f

does not issue an error message if chgrp cannot change the group ID. In this case, chgrp always returns a status of zero.

-R

If a pathname on the command line is the name of a directory, chgrp changes the group ID of all files and subdirectories under that directory. If chgrp cannot change some file or subdirectory under the directory, it continues to try to change the other files and subdirectories under the directory, but exits with a non-zero status.
