RFR: 8132541 : (process) ProcessBuilder support for redirection to discard output

[Martin Buchholz]

Thanks, I think this will be a popular feature, but...

I'm not sure that all operating systems where Java may run will have such a
"null file" (does OS400?).

If you're sure there is such a "null file", maybe there should be one or
two methods added to File to return the null output and input files.
Speaking of which, one might expect an analogue for "null input", giving
you nothing but EOF, as with "command < /dev/null".  You wouldn't want to
call it DISCARD, though.

If you added File.nullSink(), you could then do a
Redirect.to(File.nullSink())
