In Mac OS, file and folder access permissions are managed in a layered way with basic unix (POSIX) style owner/group/everyone read/write/execute modes along with, recently added access control lists (ACL) for additional access control.
Both the POSIX and ACL controls can be managed from the command line with the traditional unix command 'chmod'. For example:
Mac:~> sudo chmod -R +a "staff allow list,addfile,search,delete,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,writesecurity,chown,file_inherit,directoryinherit" path/to/folder*
What is the comprehensive list of all ACL attributes which are settable in Mac OS 10.13 (High Sierra)? What does each mean?

A comprehensive list of ACL attributes is available by consulting the man pages:
If you prefer a GUI app to show man pages download and install e.g. ManOpen (free) or Dash for macOS (a few $$).
I won't list the whole documentation of chmod:
