detach a process

[Shawn Tayler]

Thanks Guys,

That & thing was what I was looking for.  I've been using screen for some things and it's probably the most like detach that I've found but trhe & is definitely more convenient under some circumstances.  I suppoose if I got off my lazy &$$ I could learn C and make one myself.

Thanks again!

Shawn
