Maybe I did not make myself clear: I do not get an error, some filenames 
simply get eaten is $SORTED is long enough. They are in $SORTED (I 
checked) but after I submit $SORTED to for ... they are gone. I will have 
to check again. Maybe I'm just wasting time and should go directly for a 
Perl solution.

It should but it will get more complicated later, I will want to prune 
certain filenames (intersect with a list and keep what is not in it). It 
will probably be done in Perl later, I just tinker with the ideas for now. 
I would like to know what's broken ?
