You can do:

	program_name >/dev/null 2>&1 &

That will silence everything. But yeah, too much typing, too much
obscure stdout/stderr redirecting for a newbie to even begin to dream
that such things are possible.

A good default behaviour (for the app writer) is to fork() at startup,
detach from pty in child, and then exit parent.  A couple o' programs do
this.

You can disable the fork() in debug builds (or with a -debug flag) so
that you can still get error messages out of it when something goes
wrong.

I'm pretty sure this is common knowledge, just that nobody bothers to do
it. But I can dream. :)
