Thanks for all the details :)

Yes, that's what I always did and what actually motivated me
to search ("there must...").

Good point...

...since the >/dev/null looks less unattractive if you have all that
mouthful for dd. So for append, tee looks neater.
On the third hand, using here "dd" and there "tee" in a script for
the same thing... is not nice either. So if you have a mix of requirements,
yo're busted. Decissions, decissions...
In hindsight, it'd have been nice to give all those "filtering" utils a
"-o" option. Ship, sailed and things :-)
