  A command is placed in the background when an 

  ampersand ( & ) is appended to the command line.

Using output redirection with background processing, - 1.7.7.0.1

  Enter the command to use the nroff program 

  to format a file called doc, place the output 

  in a file called doc.fmt, and run in the background.

 $PROMPT$

 That is correct!

 You've got it on the 2nd try.

 Good, you understand the concept.

 Please place the command nroff doc > doc.fmt in the background

 Please type nroff doc > doc.fmt &

 I guess I must type this for you:

 $PROMPT$

FORGET1

  Observe the result on the terminal, and note that the

  number of the background job (1) is printed along with 

  the PID followed by your prompt.

 $PROMPT$nroff doc > doc.fmt &       

 [1] 1354
