ls -la symbolics… what does that last symbol mean?
Consider the following output from ls -l on OS X 10.5.8
drwxr-xr-x 3 user staff 102 Aug 26 20:21 downloads
drwxrwxrwx@ 10 user staff 340 Aug 26 20:12 images
Can anybody tell me what the @ represents at the end of the permissions section, and also how to disable/enable it. I guess this this has something to do with the directory listing permissions, as when I'm running a PHP script in Apache that needs to access a folder without the @ bit set, it doesn't list the directory contents.
Thanks!
