I can't speak to NetBSD, but FreeBSD doesn't put any user-installed programs in /bin or /usr/bin, they all go into /usr/local. Since bash isn't distributed as part of the base system, it goes into /usr/local/bin/bash
So then how do you write cross-platform scripts? You can't even do "#!/usr/bin/env bash" since I'm assuming what you're saying means 'env' is in /usr/local/ as well, but on Linux systems it'll be in /usr/.
Broken! Can we please just pick one convention and stick with it? Oh, standards... so many to choose from.
