The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "what is the function of the @ symbol in the output of the ls command in the MacOS system?"

The * * @ symbol appears in the first column of the ls-l (or ll) command output of the macos system, while the linux system does not. Usually a little attention, with the @ * symbol is mostly downloaded from the Internet files, so guess may be a security attribute sign.

Today, man ls looked at the detailed instructions and found that the situation is not just security attributes, but flag files (folders) have extended attributes. For detailed extended attribute information, you can use the ls plus-l @ option, or xattr:

Clearing the * * @ * symbol is equivalent to clearing the extended attribute, and there are two ways to do this:

Xattr-d attribute name file path: clear the specified attributes, one by one

Xattr-c file path: clear all attributes

If you just want to remove the annoying * * @ * * symbol, use xattr-c, of course.

Modify the properties with xattr-w. For more information and other options, please refer to man xattr.

PS:

The "+" symbol that appears in the ls output indicates the security attribute, that is, the file (folder) appears in the acl list.
