Re: [PATCH] tee: add option for outputting to stderr

[peter]

   I know there are other ways to do this. I've been using them :)
   Splitting output being tee's main purpose, adding the ability to make
   the destination stderr seemed useful.
   As I understood, -p sends error information about the stream to stderr,
   and this would conflict. If I misunderstood, that simplifies the patch
   somewhat!

     Why negate -p exactly?
     How common is the need for this? I've never needed it I think.
     Have you an exact use case.
     You could do this in bash/ksh like:
       seq 10 | tee >(cat 1>&2)
     You could do this on most Unix systems:
       seq 10 | tee /dev/fd/2
     Would that suffice?
