If you don't use the '&' at the end of the line, the program will run, but the 
command line will be hung until the program is terminated. If you put the '&' 
oat the end of the command, then the running program goes into the background, 
I believe, and you get your prompt back.

Perhaps some bash expert can explain it better.
