Zefram, Zoltan, Peter?) Yes. My current plan is to ignore the debate, and go for the full-on zsh solution: by default, >&p and <&p act as if p were a normal file descriptor referring to the appropriate pipe, as zsh does now; at the drop of an option, we do whatever ksh does, if it's different. Can someone who knows one end of a pipe from the other please experiment with ksh and definitively state what it does? I'd like information on pdksh, ksh88 and ksh93. If only one of them has behaviour inconsistent with zsh then it's probably a bug and therefore not worth emulating. -zefram
