    It means your file has extended permissions called ACLs.

    You have to run getfacl <file> to see the full permissions.

    See Access Control Lists for more details.

  2. via man page 'ls'

    "If the file or directory has extended security information, the permissions field printed by the -l option is followed by a '+' character."

    This generally means the file is encumbered with access restrictions outside of the traditional Unix permissions - likely Access Control List (ACL).
