$ while :; do sleep 1; done &
[1] 46950
$

Terminal 2:

Code:

$ shopt -s huponexit
$ while :; do sleep 1; done &
[1] 46988

Terminal 3:

Code:

$ ps -ef | grep -e 46950 -e 46988
  501 47102 43149   0  9:20PM ttys000    0:00.00 grep -e 46950 -e 46988
  501 46950 46940   0  9:19PM ttys001    0:00.03 -bash
  501 47100 46950   0  9:20PM ttys001    0:00.00 sleep 1
  501 46988 46944   0  9:19PM ttys002    0:00.02 -bash
  501 47099 46988   0  9:20PM ttys002    0:00.00 sleep 1
