charset=us-ascii; format=flowed Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi, Some ports, notably shells/bash, have a makeoptions config where you can select "enable use of /dev/fd". But there's no explanation given why this is advantageous or not, or if there's some kind of risk, in a freebsd context [1]. It's not enabled by default. Please can anyone explain?
