Believe it or not, I was actually trying to get information, not trying 
to make a point illustrating things.  I wasn't aware that you could mix 
the redirection modes .... but I just tested this, it does actually 
work, in both bash and sh.  Keen, I'll stow that guy away, because I've 
been asking that on occaison for years now..

Your question sounded to me like a back-handed way to illustrate 
something, but I'm  not all that deep.  I've never run into the need to 
do that redirect in tcsh, so I don't know how to do it.  I'm maybe justr 
a bit curious where you needed it, but I haven't an answer.
