Getting rid of controlling terminal

[Peter C. Bahrs]

I hope this is the correct newsgroup, so many unix., but...
I want to run a job in the background and have it disconnect from
the associating terminal without hardcoding it.
i.e. when I do a ps -guax on Berkeley I want to see a ? in the tty column.

So  program args >& file </dev/null  does not seem to work?
Any suggestions?  The problem is, on a SUN network anyway, if I use
the tty, then others cannot rlogin in to this machine (I rlogin'ed to invoke
the command).
