21,628 PointsWhat does the `jobs` program do?
On the quiz that follows there is this question:
"What does the jobs
program do?"
I figured the answer was "Lists all paused processes on the system" because nothing is listed if I don't have something that I've paused. Yet, the answer is "Shows a list of processes in your current session."
Is the latter what top
does? Top
shows a lists of processes while jobs
is for what's paused.
Am I thinking about this right?

6,762 PointsJust had a quick test:
root@ubuntu-01:/home/yang# vim hello.txt
[1]+ Stopped vim hello.txt
root@ubuntu-01:/home/yang#
yang@ubuntu-01:~$ jobs
yang@ubuntu-01:~$
What I am thinking for the correct answer "Shows a list of processes in your current session." is more focus on your current session as Jobs are per session. As you can see above outputs, the jobs in my own session "yang" doesn't show any paused processes on the system. However, there is one paused process in root session.
In other words, we cannot simply say that "Lists all paused processes on the system".
This is just my thoughts. Any comments are welcome. :)

Courses Plus Student 17,330 PointsThink of top as a dynamic list of all processes on the system across all users and jobs as only what the current users session is running. To see this, at the terminal run jobs, then start a process in your session in the background and then run jobs again.
[userprompt ] ~ $ sleep 100&
[userprompt ] ~ $ jobs
