transform to progressive

I use jhead to preserve the exif-information when I transform photos to progressive:

Code:

jhead -cmd "jpegtran -progressive -outfile &o &i" TEST.jpg

Is there a way to do the same using exiftool?

(Not necessarily with jpegtran)

Here is one way to do it:

Code:

jpegtran -progressive TEST.jpg | exiftool -tagsfromfile TEST.jpg -exif - > out.jpg

This will transfer the exif segment as a block, which presumably is what jhead does.
However, instead of -exif I would suggest using -all:all to
transfer all metadata.
