Possible Duplicates:
what is the @ after the permissions for in ls -l on a mac?
ls -la symbolics… what does that last symbol mean?

Running a "ls -l" on a folder I get : 

....
-rwxrwxr-x@ 1 me  staff   466676 Mar  6 05:38 pgsql.so  
-rwxrwxr-x@ 1 me  staff   709156 Mar  6 05:38 xcache.so  
-rw-r--r--  1 me  staff      802 Jul 14 13:25 xdebug.a  
-rwxr-xr-x  1 me  staff   274384 Jul 14 13:25 xdebug.so  
....

What does the '@' mean?

The "@" means that the file has "extended attributes" associated with it.

If you do "ls -@ -l", you can see what attributes there are for each file. You can also do something like "xattr -l pgsql.so" to dump the attributes for a particular file.

Typically they're stuff like old-school FinderInfo, text encoding info, or the "quarantine" info that gives you the "This file was downloaded from the web, are you sure you want to open it?" warning.

Extended attributes are not unique to the mac platform. A number of operating systems support this file-level feature. – Stefan Kendall Jul 14 '10 at 16:46
@iftrue: ultimately it's a file system feature, though. – Joey Jul 14 '10 at 17:06

According to the man page, it means there are extended attributes.
