$ pwd
/udir/jroquet
$ ls -l .screenrc
lrwxrwxrwx 1 jroquet kmem 37 2009-10-16 14:56 .screenrc ->
/udir/jroquet/Arkonf/screen/.screenrc
$ ls -l .screenrc(:A)
-rw-r--r-- 1 jroquet kmem 1521 2010-02-24 18:44
/udir/jroquet/Arkonf/screen/.screenrc
$ echo .screenrc(:A)
/udir/jroquet/Arkonf/screen/.screenrc

I'm running Ubuntu Linux 10.04, zsh 4.3.10
