    Lossless rotate using command line

    Is it possible to perform a lossless rotate from the command line?
    If this could be done based on the EXIF information, perfect, but just a lossless rotate from the command line would work for me as well.

    From this file :

    /rotate_r - rotate input image to right
    /rotate_l - rotate input image to left

      batch-rotating losslessly via commandline

      Hi!
      I also would like to rotate jpgs losslessly via commandline.
      Using only /rotate_r does not do the trick for me, because I would like to turn it without opening and saving it.
      But then, if I use /rotate_r /convert=$F, perhaps with a quality value, it is not lossless anymore.
      How can I (batch-)rotate jpg-images without opening them at all?

      Thanx for your help!
      Kind regards

        Appendix: Found new Jpg_Transform-plugin - but problem remains

        By chance I hit onto the new Jpg_Transform-plugin (after 4.10)
        - but my problem remains: the image opens, instead of being losslessly and permanently rotated.
        Thanx a lot for your input!
        Kind regards
