If you just want to keep the output hooked to the terminal, you can say

	(command >/dev/tty &) >/dev/null

If you want to be able to redirect the output of your script you'll have
to get a little fancier.  One could go wild with redirections in sh, but
here's the perl way:

	perl -e 'fork || exec "command";'
