I don't know why, but a search on either Bing or Google for "posix shell" points to the older version.

That's the one that I use.

I also prefer the plain Apache directory list for all the POSIX.2 utilities, so I am definitely sticking with Bing & Google's recommendations.

Probably because it's only been out for a few months. I've found Google is fantastic at returning Python 2.6 and Python 3.7 or 3.8 documentation without jumping through hoops in my search terms (if it lists the official documentation at all rather than blogs and random tutorials), but lousy at getting anything current. I imagine they have the same problem with other new material.

But if you want the current documentation and the Apache listing format: https://pubs.opengroup.org/onlinepubs/9799919799/utilities/

Thanks, I have added that to my stash.

Interesting that the old URL only differs by one character; changing the first 6 to a 7 gets the later list.
