Nice. I habitually use sed because most of the time there is much more
to do, like replacing spaces with underscores etc. And I have to thank
you Colin, because it has now become clear why my filename "repairs"
sometimes dont work. If it contains two space characters in a row and
the sed expression shall replace them with a single underscore for
example, it will not work without proper quoting because the two spaces
will become one when entering sed. Ive had lots of head scratching about
that :)
