Ok, for the benefit of anyone else who wants to know... This is what I've found out. (If you try this, do so at your own risk. Playing around with file permissions and such can be dangerous, but you already knew that right?).
---
Add ACL user _www to all files in the current folder:
chmod +a "_www allow read,write,append,readattr,writeattr,readextattr,writeextattr,readsecurity"
.
--
Add ACL user -www to specific file:
chmod +a "_www allow read,write,append,readattr,writeattr,readextattr,writeextattr,readsecurity" "File Name"
If the file name has a space, either put it in quotes or enter it as File\ Name
--
Add ACL user -www to specific folder:
chmod +a "_www allow list,add_file,search,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity" "New folder"
--
Viewing ACL users:
ls -ela (e attribute shows info)
(FYI if viewing the file list, the + after file POSIX permissions means it has an ACL user)
--
Removing ACL user _www from any of the above: (You can also use "Get Info" on the file/folder and just click the - to remove the user)
(if only one ACL user, or to delete all ACL users:)
chmod -a file.txt
(if more than one ACL user, use the ACL ID # that precedes it when viewing ls -l)
chmod -a# 1 file.txt
(the pound-sign tells it to use id number, followed by a space and its number.)
===
The chmod attributes should be on one line. (For custom attributes, you can omit ones you may not need). If someone more instructions to add, please feel free. I woud like to see this as an Apple Script or application - maybe I will look into it someday, or if someone else has more time.....
I hope this helps someone!
..Jim.
