With zsh 3.1.9 under Solaris 2.7:
vin:~> rup >(hilight 1) <17:49:12
/dev/fd/12: RPC: Unknown host
zsh: exit 1 rup >(hilight 1)
What does this mean?

It means you've forgotten the extra `>'. >(hilight 1) produces a filename
into which you can write, which will serve as output for the process
`highlight 1'. You need:
rup > >(hilight 1)

Peter means "input",
of course.

OK, is it the same thing as rup >>(hilight 1) ?
(I'm reading mails from 1998, and either things have changed or there
are not very clear.)
The problem is that rup does block-buffering. Neither a pipe nor >(...)
prevents it to do so. Is there a way (at the shell level) so that rup
thinks it's writing to a terminal (thus does line-buffering)?
