Please can anyone explain? > >Do you have a floppy drive? no. I admit i'd not thought of floppy drive at all. In 2021, who does? But the context in which this option is in, is confusing. The option is for fdescfs with "enable use of /dev/fd". I don't know what fdescfs truly is, apart from something to do with file descriptords, and not floppy drives. Look here to see what I mean: https://cloud.zyxst.net/~john/FreeBSD/ports/bashc/bashc.png I think "enable use of /dev/fd" might be a bug; maybe it should say "enable use of /dev/fdescfs" ? In which case my question should be "which is best - /dev/fdescfs or fifo?" -- J.
