I installed princexml for Mac. With ls -alF, I have -rwxr-xr-x@ 1 prosseek admin 14190120 Jun 8 16:11 prince*. What's the meaning of @ in -rwxr-xr-x@?

And when I tried to execute the binary, I got ./prince: Operation not permitted error message. Does this have anything with @?

The error message is unrelated to the @. But I don't have a guess on why it does occur. Did you untar/unzip the prince-macosx.tar.gz in Terminal or via double click in Finder? – patrix Jun 9 '12 at 15:31
@patrix: I did click in Finder (PathFinder to be precise) to open the tar file, after untag it in command line, everything works fine. – prosseek Jun 9 '12 at 16:35

It means that the file has extended attributes. To see these attributes, run xattr -l file, to see the extended attributes of a particular file, or ls -l@ to see the extended attributes of all files in a particular directory.

See the man page for xattr as well.
