The original UNIX definition was that a daemon had no associated tty, but I'd hesitate to say that it isn't controlled by another program -- to me, the program that spawns it exerts control.

Controlled by another program?

The original UNIX definition was that a daemon had no associated tty, but I'd hesitate to say that it isn't controlled by another program -- to me, the program that spawns it exerts control. It should be sufficient to say it has no user. Howard C. Berkowitz 20:11, 1 October 2009 (UTC)

Good point. I was thinking of daemons that respond only to events, but of course programs can generate those events also. A daemon is controlled by its parent, even if that control is only to terminate the daemon.
Webopedia uses the concept of "background process" http://www.webopedia.com/TERM/D/daemon.html, meaning "not controlled by the user". I'll delete "or another program".
