The original poster asked how to redirect to a *command*. You've shown how
to redirect to a *file*.
In csh, one possible way to do it (when working at a tty) would be:
(program > /dev/tty) |& command
A similar approach will work in sh (and probably ksh), although there's
probably some better way to do it with various hideous file descriptor
reassignments (I don't use the bourne shell a lot, so I don't qualify to
invent hideous file descriptor reassignments :-):
(program > /dev/tty) 2>&1 | command
