Status reporting
The shell learns immediately whenever a process changes state. It normally
informs you whenever a job becomes blocked so that no further progress is
possible, but only just before it prints a prompt. This is done so that it
does not otherwise disturb your work. If, however, you set the shell variable
notify, the shell will notify you immediately of changes of status in
background jobs. There is also a shell command notify which marks a
single process so that its status changes will be immediately reported. By
default notify marks the current process; simply say `notify' after
starting a background job to mark it.

When you try to leave the shell while jobs are stopped, you will be
warned that `You have stopped jobs.' You may use the jobs command to see
what they are. If you do this or immediately try to exit again, the shell will
not warn you a second time, and the suspended jobs will be terminated.
