What do you mean "decent" shell?!? :)  Yes, you are correct in that this
method is for bourne shell (/bin/sh) and it's many derivatives (bash, ash,
zsh, ksh, etc.).  csh and tcsh let you redirect stdout or stdout AND
stderr, but not stderr by itself.  The following trick works if you are
want to direct stderr to /dev/null:

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

That routes stderr and stdout ("&>") to /dev/null and just stdout to the
screen.  csh is nice, but not for scripting. :)
