Checking mckusick's source distribution, it seems that the -f option
(along with sanity) came in with 4.4BSD. It was in the original
sources imported into FreeBSD. 4.3BSD had such a bizarre syntax that
I suspect whatever you emulated must have come from a later date.
But options are an issue, notably with GNU software, which has a
completely different lineage. Just look at FreeBSD ls(1) and GNU
ls(1).
What really blew my gasket is that "stty -f" on *BSD is "stty -F" on
Penguin/OS, despite them copying every other flag.
I'm pretty sure the addition of "stty -f" and "stty -F" is a
fairly
late innovation. i.e., it wasn't there when Linux "copied" stty's
user interface.
In BSD 4.3 and early Linux (which is when I still was maintaining
Linux's serial driver) you always had to do:
stty dec < /dev/ttyS0 Really, why did those young whippersnappers had to add
an option, when
redirection worked perfectly well and required one less character to
type? :-)
Creeping featurism!
