The chgrp (from change group) command may be used by unprivileged users on various operating systems to change the group associated with a file system object (such as a computer 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.
