That seems rather ill-advised, but I'll trust that you know what
you're doing.

That may not be the case, and seems rather unlikely.  So, what you're
complaining about is the output to your terminal, correct?

One possibility is that foobar may be writing directly to your
terminal, rather than STDOUT.  If so, nohup won't help you here.  It
may still be possible to redirect that output somewhere, but I don't
have time to explain how, so first figure out if that is what is going
on.  If so, I'll explain later, after you reply.

If foobar is a shell script, look for it to be sending output to
/dev/tty, or some other redirection.  If it isn't, then either you'll
need to supply more info, or you're on your own.
