There is a question: "What does the jobs program do?" And the right answer is "Show a list of processes in your current session" instead of "Lists all paused processes on the system". Could anybody explain me why? Thank you in advance. P.S. Every time when I hit "Enter", the quiz behind the overlay with the window where I'm typing get it like attempt answer. I think it's not right.

until false do puts 'hi'; sleep 5 end
... then pressed Ctrl-Z and typed bg, the process would continue printing 'hi' every 5 seconds and it would show up in the jobs list, even though it's not paused.
Plus, the second answer talks about listing all paused processes on the system, which isn't true since it's a session-specific command.

13,851 PointsHey there! From the video I misunderstood, that "jobs" lists only paused processed. So, the question more about <i>"in session"/"on the system"</i> thing and the right answer is right) Thank you for the clarification!
