   I know, not as pretty... On the Amiga this could be handled quite easily
   just by making PIPE=pipe:temp. But the rest of the command is more managable
   using the UNIX pipe syntax.

Well, with pipe: it works just fine. But using a real file for $PIPE
means you buy back many of the problems pipes were invented to get
around.
