This question already has an answer here:

I started encountering the following problem when I was trying to delete a set of files when I started seeing the following error on my MAC with macOs, Mojave.

"The operation can’t be completed because you don’t have permission to access some of the items."

When I looked closer, one file with a specific file permissions, was causing this issue.

-rwxr-xr-x@ 1 adikshit  1668562246  10963817 Dec 26  2009 DSC_1202.NEF
-rwxr-xr-x  1 adikshit  1668562246  11273265 Dec 26  2009 DSC_1203.NEF

The file in first line was fine and could be deleted. The second file without the @ symbol was causing the error.

What does this symbol mean.

I have looked at https://www.guru99.com/file-permissions.html but it doesn't explain the attribute @
