Have they replaced bash with a good BSD licensed shell, or are they still rolling with an ancient version of bash? Hard to see that as a "positive" if they are...

My most recent installation of FreeBSD came with tcsh by default.

But since installing whichever shell one prefers is so easy, I don't see any real problems there.

Oh, I know FreeBSD defaults to tcsh. My concern is that OSX has chosen to ship ancient GPLv2 software instead of modern BSD software. I can't consider this a good thing for anyone but ideologs.

They ship a pretty recent zsh though :)

Ah, that's good. I wonder why they don't default to it. zsh is a great shell to default to.

They used to, before 10.3 or 10.4 or so. I suspect that it was offputting to people moving from Linux.

I believe jlgreco was asking about Mac OS, not BSD.

Nope it's still an old Bash, with a really slow grep!

Mac OS is still shipping with Bash 3.
