ls -la question

[rich1812]

Hello, when I use the command ls -la. terminal outputs a lot of info.
-rw-r-----+,
--w-------@
drwxr-x---.

I understand the d for directory Rex are the permission, but what are the '+' and '@'? '@' means soft link I suppose but what is the '+'? Thanks

The plus (+) means there's an access control list for controlling additional permissions.
The at symbol (@) means there are extended file attributes.

Perhaps this might help

I'm no Unix guru, I learned some of this stuff a long time ago. Perhaps someone with more knowledge will chime in.

Here's the man page for the 'ls' command:

Look under the heading "The Long Format" (find it on the page) for the description of '@', '+', and the mode characters.

A description of ACLs will be found at the man page for chmod (link is at bottom of ls's man page, under SEE ALSO heading).

Or you can open up Terminal and type in 'man ls' or 'man chmod' to read the built-in manpages.
