Fg (Unix)

In Unix land, where shells do roam, Job control is their special home. A job, you see, is a group of friends, Processes together, their journey never ends. With job control, the shell takes the lead, Suspending, resuming, it's all they need. Pause a job, let it take a rest, Resume it later, at your behest. Terminate a job, bid it farewell, All processes stop, their stories quell. No more running, no more strife, A peaceful end to their digital life. But job control can do much more, With signals, it opens a brand new door. Send a signal, a message to convey, To the job, to guide its way. Job control in Unix, a fascinating art, Multiprocessing's where it plays its part. Distinguished from the rest, it stands tall, In the world of job control, it reigns over all.
