Are you calling sudo to run the command? A terminal is required by sudo to
ask for the password by default. Maybe this is the reason a terminal is
opened automatically. If you are indeed running sudo to run the command,
you could pass the -S option in sudo, then check the output when it is
asking for a password. This is how Anjuta do it (though with some
differences, since Anjuta use fork and exec, and the patches to use spawn
functions of GLib instead are not yet committed).
