以前从 TimeMachine 里 Copy 东西出来，权限都会如下，带 @
drwxr-xr-x@
以前直接
sudo xattr -rc xx 就可以清除扩展的权限
14 的 M1 到了，用原来的方法，xattr 后权限多了个+
drwxr-xr-x+
用 ls -laeO@查看一直有扩展权限存在，如下
drwxr-xr-x+ 11 Ben admin - 352 2 5 20:53 sites-available 0: group:everyone deny add_file,delete,add_subdirectory,delete_child,writeattr,writeextattr,chown
有人遇到过吗？

删除是 xattr -d |

@deplivesb In some permission systems additional symbols in the ls -l display represent additional permission features: + (plus) suffix indicates an access control list that can control additional permissions. . (dot) suffix indicates an SELinux context is present. Details may be listed with the command ls -Z. @ suffix indicates extended file attributes are present. https://en.wikipedia.org/wiki/File-system_permissions#Symbolic_notation |
