permissões de arquivo no Unix

Question

Estou trabalhando no Solaris Unix. Eu tenho um arquivo com permissões:

-rw-r----x+

O que significa + no final?

    

Answer 1

De man ls :

If the file or directory has extended attributes, the permissions field printed by the -l option is followed by a '@' character. Otherwise, if the file or directory has extended security information (such as an access control list), the permissions field printed by the -l option is followed by a '+' character.
