The user invoking chgrp must belong to the specified group and be the owner of the file, or be the super-user.
No errors are reported when the -f (force) option is given.
When the -R option is given, chgrp recursively descends its directory arguments setting the specified group-ID. When symbolic links are encountered, their group is changed, but they are not traversed.
