Apart from redirect output from a command to another command.

I don't *care* whether my bash was correctly built, because it's *as supplied by the vendor*. That a vendor supplies what you deem to be a broken shell demonstrates that diff <(echo -e "oranges") <(echo -e "apples") can't really be relied on. That it also doesn't work in some non-bash shells also demonstrates that, as I said in node Re: redirect output from a command to another command "it's a neat trick, but I'd only use it in shell prompt one-liners, not in scripts that might get used elsewhere".

All I was doing was pointing out that the shell version that started this thread isn't that great. All consequent discussion has been because of your misunderstanding of what I was commenting on.
