Have you ever seen this symbol in a bsd or unix system? my system is mac & nbsp; OSX, and a strange symbol is found in the permission list. There is no way to send a picture here, so I will post the text.

My system is mac OSX, and a strange symbol is found in the permission list.
There is no way to send a picture here, so I will post the text.
Drwxr-xr-x + 48 angryfrog staff 1632 11 20.
Drwxr-xr-x 6 root admin 204 10 10 ..

See Row 4,-rw-r -- @, and finally there is a "@". This symbol is not found on centos. I don't know about other linux systems.
Since the mac OS kernel darwin is based on the freebsd kernel openbsd, I would like to ask if anyone knows the meaning of this symbol. I have no answer to my questions in cu bsd. I also asked questions in the csdn unix zone. But no answer is returned. I even have some doubts that this is a special symbol of darwin.
I have never heard of it. if you know what it means, please let me know what it means.

I checked it for a long time yesterday and did not find the cause. I checked my mac and linux server and did not find this symbol. it turned out to be an extra thing. I learned it, thank you very much for publishing the answer.

The answer is answered in the unix version. This attribute indicates that this file or directory contains additional attributes. For example, if you download a file on a mac and double-click it to open it, a message such as "This file is not secure from network download" is displayed. this identifier comes from this additional attribute, you can run the xattr-l command to view details.
The extra attribute is not unique to mac, except that the @ symbol is only displayed on mac after ls-al.
Copy the package file from the mac to linux. this attribute will cause linux to fail to be opened. Therefore, you need to remove this attribute from tar-x during mac packaging to linux.
Don't close the post, just remind everyone.
