[question] similar projects for other BSDs shells? about oksh HOT 7 CLOSED

I don't think there's any separate or special shell history specific to the BSDs. Just the history of shells, some of which happen to be developed and maintained by BSD projects.

/bin/sh is:
ash on FreeBSD, NetBSD, and DragonFly
ksh on OpenBSD

I'm sure ash on FreeBSD and NetBSD are mostly compatible, slightly diverged. ash on DragonFly may just be a direct vendor sync from FreeBSD with any needed patches on top.

oksh and loksh shouldn't generate different outputs ever (modulo syncing with OpenBSD). You're right, our scopes are different: loksh aims solely at Linux, whereas oksh aims for as many environments and compilers as possible.

Thanks.

So you're not aware of projects aiming to build the FreeBSD or NetBSD sh (i.e. with their current code base) for linux or other platforms?

I would imagine that with the existence of dash, no one finds it necessary to port ash.
Repology.org also doesn't know of any modern ash port to another operating system.

from oksh.

Sure, dash is quite fine, but as I bet you know the devil is in the details, and some shells do mostly fine except where they don't (for instance, OpenBSD ksh doesn't apply "$@" correctly when IFS is non-standard).

So for the sake of compatibility testing, it's not enough to assume IMHO that if it works in dash then it would also work in BSD ash.

Anyway, thanks again. Maybe I'll try to ask the NetBSD folks about it.

Hmm.. now that I think about it, does OpenBSD have ash which is reasonably close to FreeBSD and/or NetBSD ash? If yes, maybe the oksh portability framework could be used to build that as well?

The "$@" bug has been fixed: https://marc.info/?l=openbsd-cvs&m=160001156508985&w=2

There is no ash in OpenBSD's sources. It was removed something like 20 years ago. /bin/sh is ksh.
I did however make a port of NetBSD ash some time ago to do some unrelated work: https://github.com/ibara/ash
You can build it with make obj && make but make sure to run cvs diff first so you can see the changes I had to make.

Huh, interesting. I reported it on the Sep 12th here https://marc.info/?t=159986957700001&r=1&w=4 and I've been following the thread, but there were no further replies so I assumed it just stalled again (previous time was 4 years ago).

Much appreciated. I'll take a look.

FWIW, I asked at #netbsd on IRC, and was told there are no ports of their default shell to other platforms.

(feel free to close this issue at any time)
