Ouch - this looks like a POSIX compliance bug in exec; I'm adding bug-autoconf to the distribution in case we want to document this corner case bug in the shell portability section. POSIX states that exec is supposed to bypass shell builtins (and while special shell builtins, like 'exit', give undefined behavior when passed to exec, regular shell builtins, like 'fg', are required to exist in PATH even if they can't quite do as much work as their builtin counterpart). Do you know which shell heritage the OpenBSD /bin/sh derives from? | $ PATH=. /bin/sh -c 'nice mknod --version' | head -1 | mknod (GNU coreutils) 6.10.188-7cb24 | So I'll go with nice. Sounds nice to me (sorry, couldn't resist :) - -- Don't work too hard, make some time for fun as well!
