Leopard, 'ls -l' and extended attributes

Under OS X v10.5 the permissions column from ls -l contains extra characters which I haven't seen before.

$ ls -l
total 16
-rwxr--r--@ 1 me  me  165 Jan  2 06:38 run_webalizer
-rw-r--r--@ 1 me  me    0 Jan  3 10:04 run_webalizer.scpt

The man pages didn't say anything about these @ characters. Google was no help since it ignores punctuation characters like "@".

Eventually I realized that, since I had done an "upgrade" installation of Leopard, my man pages might be out of date. Indeed they are: Apple's online man pages explain @ and much else that's new in the ls command:

If the file or directory has extended attributes, the permissions field printed by the -l option is followed by a '@' character. Otherwise, if the file or directory has extended security information, the permissions field printed by the -l option is followed by a '+' character.

And

The following options are available:
     -@      Display extended attribute keys and sizes in long (-l) output.

Ah, Bach. Look at some of the interesting tidbits revealed by -@:

$ ls -l@
total 16
-rwxr--r--@ 1 me  me  165 Jan  2 06:38 run_webalizer
	com.macromates.caret	 33 
-rw-r--r--@ 1 me  me    0 Jan  3 10:04 run_webalizer.scpt
	com.apple.FinderInfo	 32 
	com.apple.ResourceFork	754 

So that's how TextMate knows where to put the cursor when I re-open a file.

Now I just need to figure out how to get my man pages up to date.
