OK. I haven't provided enough "specificicim". I resume the render job with the
following command:

$ povray cube_of_spheres.ini
....
^C        <--- (Ctrl+c)
$

To show its output, I modify it as the following:

$ povray cube_of_spheres.ini > cube_of_spheres.out 2>&1
^C        <--- (Ctrl+c)
$

Below is "cube_of_spheres.out":
