  Background processing is the ability to run a

  job unattended.  Several jobs may be run at once in

  the background, however, only one may run in the 

  foreground.  Note processes B1, B2, and F1.

 To perform process control from the terminal level or from your

 program using system calls you need to know the PID!

 B4

???BSD: is different for ps

 The UNIX command for obtaining process status information is ps.

 To obtain information about your current processes, enter 

 the ps command on the terminal.

 $PROMPT$

 That is correct!

 You've got it on the 2nd try.

 Good, you understand the concept.

 Please type ps

 Please type ps

 I guess I must type this for you:

 $PROMPT$

FORGET1

 Observe the result on the terminal!

 ps

 Note the asynchronous finish of the processes ...

 Note that by using the process id's, the processes

 can be sent signals, killed or moved from background

 to foreground and vice versa!
