If it's running in the foreground, you can suspend it with ctrl-Z, and then background (unsuspending it) with the "bg" built-in shell command. That's nice, but even nicer would be if you could do it one go. Foregrounded to backgrounded in one go doesn't sound like too much to ask, and seems like an obvious idea.

Those are all the questions I can think of. Incidentally, I've been wondering about trying some pair-working mini projects, defined as: in the first 3 days, set objectives so that the two of you can, with 95% pr...
