---------------------------------------------------------------------- (0004012) kre (reporter) - 2018-04-26 16:03 http://austingroupbugs.net/view.php?id=1039#c4012 ---------------------------------------------------------------------- I have no idea why this issue is still under discussion, can we not just stop? It doesn't really matter why I used to use -$- (it was in my sh code all over the place which is why I would have preferred to keep the idiom, but I think I have removed it all now). I know that the original sh did not include 'c' in $- - that's why -$- was able to work (though the one liners that tend to be used with sh -c would rarely have needed it anyway.) And I know there was no "set +". I wasn't really aware of -r (that was just done when the name was rsh, I don't believe that was ever in $- in the early shell, not that I would have cared, or noticed, since (that) rsh was never of any interest). I believe "set +o" is much more recent. I also don't believe there are any "forbidden" flags, there are some that cannot be set in some shells -- but can be in others - though not always with any effect,. The 's' flag in the NetBSD shell is essentially a 1 bit variable - scripts (if they're insane) can use it however they like, it can be set/reset but that does nothing (except reset the state of the shell at startup, if it has not been changed). If the shell is reading stdin, it is reading stdin, and turning off a flag does not change that (where otherwise would it read the next command from?) Nor does turning it on cause the shell to suddenly leave its script and start reading stdin. I suppose it could just be left out of 'set' but then it would need to be special cased in command line processing (as -c requires) and that would take extra code (and so introduce more bugs) - easier to just set it at startup, then leave it and ignore it. Unless there is really some problem with the accepted text, which I do not believe there is, can't we just concentrate on issues that need actual resolution, rather than just making noise?
