I'd like to ask more in this question http://superuser.com/questions/495336/what-is-the-automatic-maintenance in the way that I want to know what *EXACTLY* is done during maintenance (ie a command/script that shows a full list of tasks/processes)

I've read 
http://superuser.com/help/asking and https://meta.superuser.com/questions/3533/how-to-ask-a-question-which-is-similar-to-other-questions-but-not-exactly-simila but I can't figure out whether to edit the original question or ask a new one.  

Any suggestions?
