To logout when there are stopped jobs:
man ls .... .... <Ctrl-z> Stopped logout There are stopped jobs. fg man ls --More--(8%) q logout
The user starts a job by entering the command to view the manual page for the ls command. They then "stop" this job with a the control key combination Ctrl-z.
It is not possible to logout until this "job" is started again and they quit from using it. They are then able to logout.
