Reread the bit of text I quoted. Read my reply. How does my reply
address the problem scrappy had?
The bits of ps output I quoted were only serving to demonstrate actual

No, but changing the CMD column is only eye-candy. Its not necessary to
be able to tell which processes are children and which is the parent.
