I'm not subscribed to the list, I had missed the message of Stephane
Chazelas. What proposal do you want please?

[n1]>&n2    Redirect standard output (or fd n1) to the same "open
            file description" as on fd n2.

[n1]>&n2    Redirect standard output (or fd n1) to the same
            resource as open on fd n2.

[n1]>&n2    Copy fd n2 as stdout (or fd n1)

Thanks,
