No solution was given in any ancestor to your post. I don't even know what you're disagreeing with. I humoured your games, but now it's time for you to be clear. Do you disagree with any of the following?

• Your bash was incorrectly built.
• Your bash being incorrectly built does not speak to the portability of the /dev/fd method.
• The portability of the /dev/fd solution is not related to the portability of bash.
• /dev/fd is not portable between OSs or even between systems with the same OS.
• Named pipes are quite portable.

If so, let's discuss that. If not, then we're off topic.

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.
