Can a Bourn Shell Script put itself in the background?

[Nerius Landys]

Just a thought, you can use the screen utility depending on what you
are trying to do.  For example if you want to start a job, long out of
the machine completely, and then return to your job to see how it's
running, you may choose to run screen.

> screen bash
(Press Control-A then d)
(Logout from shell)
(Log back in)
> screen -r

Hope this sheds some light.
