我遇到了一个问题，即各种文件和文件夹的 ACL 分配中有很多重复项。我不会详细介绍这种情况发生的原因（我们可以感谢Server.app错误），但最重要的是，我现在有数千个具有以下属性的文件和文件夹：
$ ls -le：

最终看起来这里只有两个任务：
user:_spotlight allow list,search,file_inherit,directory_inherituser:myusername allow list,add_file,search,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,file_inherit,directory_inherit
我可以用类似这样的方法去掉所有这些属性（我用它find来确保我不会失去理智，因为它运行了几个小时，我想确保它仍然在工作而不是挂起）：
sudo find $PATH -print -exec /bin/chmod -vv -h -N {} \; -exec /bin/chmod -vv -R -L -N {} \;
但这只是删除了所有内容。由于这里有共享，我是否可以简单地销毁所有这些 ACL 并让 macOS 上的 SMB 共享一切正常，还是至少需要应用一些最小的 ACL 集chmod -R +a "user:mysuername allow list,add_file,search,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,file_inherit,directory_inherit" $PATH？
