I haven't done it, but I'm pretty sure the convert program from
ImageMagicK does exactly what you want. See:

man convert | grep -A5 crop

As far as a script, all I can recommend is a loop that backs up
the original to a new name, converts and renames the converted, so you
can start it again if you get only half way through for some reason.

Or, you can just redirect ls into a file, use Vim to convert and rename
each file individually.

HTH,
