Right, otherwise people would complain a lot more about ksh than they currently do looking at the web... I'm pretty sure I have shell scripts that rely on /dev/fd/N working as an exec'd command argument for N > 2. An example of an exec'd program that uses N > 2 without /dev/fd/N is gpg, with the --passphrase-fd, --command-fd, --status-fd options. I would be unhappy if these broke. ...unless I've misunderstood what this thread is about from my very cursory skimming of it.
