Yup, doing 'ls' wasn't what I needed: it was just the first
nonsense/nontrivial example it came to my mind. I was just wondering if
there were a syntax  for manipulating expanded strings instead of
variables, because at first saw it seemed something lacking: I usually
don't like to have temporary variables just for a  single manipulation,
whatever is the language. Anyway, I figured that using the 'for'
construct for my task is more compact and safe almost as well as doing 
without. Thanks a lot for the hint.
