you can have in this way many stopped jobs, which you can see using the 'jobs' command
you can kill anyone of this jobs by issuing "kill %n", where n is the number of the job as listed by jobs...
fg put the job to foreground and activate the process again
jobs display your stopped/backgrounded jobs
kill %1 send signal TERM to the job numbered %1 in the job list
