chmod man page

Question

chmod man page

On this page that tells me how to set up Apache on my new Ventura iMac, there's a line that says how to allow the _www user access to ~/Sites. (chmod +a "_www allow execute" ~) It's in a syntax I've never seen before. Where can I find documentation for that command?

iMac (24-inch, M1, 2021, 2 ports)

It is an Access Control List (ACL).

ACLs are described in the “man chmod” man page under the Access Control List section.

ACLs can provide very granular permissions access or denial, on a per user or group basis.

Google “macos ACL examples” and you will find some other usage.
