<P> The chgrp (from change group) command may be used by unprivileged users on Unix - like systems to change the group associated with a file system object (such as a file, directory, or link) to one of which they are a member . A file system object has 3 sets of access permissions, one set for the owner, one set for the group and one set for others . Changing the group of an object could be used to change which users can write to a file . </P> <P> chgrp (options) group FSO </P>
