As far as I know, it doesn't exist, other than vi or your favorite
editor.  In fact, there are a number of CRUD[1] functions missing from
the tools that manipulate user and group information.  For example,
there's no command to query the members of a group.  Instead, you have
to use grep, sed, or some scripting language.
