These will work as long as you don't supply an ambiguous job_spec.
Notice that, only kill requires the ''%'' so that it knows we are providing it with a JOB_SPEC rather than a process id.

!!How this works
Internally each command line (job) gets it's own ProcessGroup assigned to it by the shell when it creates the job using [setsid(2)]. While the command is running in the foreground it recieves any signals from the tty layer (such as [SIGTSTP], [SIGINT], [SIGQUIT], [SIGHUP] etc).
