    Mac permission @ and +
    Hi guys,
    I apologize if this has been asked but I searched the forum without finding what I was looking for. I am switching to a Mac from using Linux(Fedora) and I was wondering what the @ and + are for File/Directory permissions?

    [greg@ ~] ls -le
    total 0
    drwxr-xr-x 5 greg staff 170 Oct 21 13:39 Bin/
    drwx------+ 3 greg staff 102 Oct 20 13:46 Desktop/
    0: group:everyone deny delete
    drwx------+ 4 greg staff 136 Oct 20 13:46 Documents/
    0: group:everyone deny delete
    drwx------+ 8 greg staff 272 Oct 21 09:18 Downloads/
    0: group:everyone deny delete
    drwx------+ 36 greg staff 1224 Oct 21 13:40 Library/
    0: group:everyone deny delete
    drwx------+ 3 greg staff 102 Oct 20 13:46 Movies/
    0: group:everyone deny delete
    drwx------+ 4 greg staff 136 Oct 20 15:14 Music/
    0: group:everyone deny delete
    drwxr-xr-x 2 greg staff 68 Oct 21 14:01 Opt/
    drwx------+ 11 greg staff 374 Oct 21 10:57 Pictures/
    0: group:everyone deny delete
    drwxr-xr-x+ 5 greg staff 170 Oct 20 13:46 Public/
    0: group:everyone deny delete
    drwxr-xr-x+ 5 greg staff 170 Oct 20 13:46 Sites/
    0: group:everyone deny delete
    drwxr-xr-x 5 greg staff 170 Oct 21 14:01 Src/


    Also I was curious as to what 0: group:everyone deny delete means as well as the 5, 3, 4, 11 before greg staff.

    I appreciate the help!
    Regards,
    Greg Sieranski

    They are reflecting ACL permissions vs the POSIX you are used to.

    chmod will allow you to change ACL permissions.
