If you wanted to save some shell execution time, you could move the `tr`
calls to the bottom of the loop to avoid doing it for files that the
`if` block is going to discard. But is that significant? I doubt it.
This actually made a measurable difference, so I included that change in
the committed patch.
(I didn't quite understand why you use printf instead of echo, given
that both are shell builtins in any case.)
printf is nowadays preferable over echo in portable shell scripts. See
for example

and
