Here is an example python program (note os.system call, that's what you
need if you use python):

import os

for f in os.listdir('.'):
    if f.find('.jpg') > 0:
        tempfile = f[:-1] + 't'
        os.system('jpegtran -rotate 90 %s > %s' % (f, tempfile))
        os.remove(f)
        os.rename(tempfile, f)
