By "something similar" do you mean a way of piping stderr, or a head utility?

A head utility is trivial to code.  Of course, a way to pipe stderr is another matter.

What version of Windows are you using?

Modern versions support 2> to redirect stderr to a file.  But 2| doesn't seem to work 
correspondingly (at least under Vista, don't know about Win7) - by the looks of it it just 
passes 2 as an argument to the program and pipes stdout as usual.

Maybe a utility could be made along similar lines to Rederr (which I published somewhere 
on these 'groups OUAT)....
