None of the paths I have in the
/etc/paths.d directory are being added to
$PATH in any of the shells on my High Sierra system. Presumably there’s supposed to be something in some file that says to look in
/etc/paths.d when a shell starts; what is that something and where should it be?
Ideally I’d like to know a proper way (i.e. not some weird hack that technically solves the problem but will cause more problems down the line, because that’s almost certainly how I got into this mess) to get
$PATH to use the contents of
/etc/paths.d for at least bash and zsh.
