I have successfully used convert IMG_6081.CR2 IMG_6081.JPG; then I tried mogrify -format jpg *CR2 in the folder, with about 700 images for a total of 16 GB; after a long busy while, the task finished with no errors but no JPG had been produced: I checked /tmp and they all were still there instead of being moved over the originals. What did I do wrong?
I'm using ImageMagick 6.6.0-4 2012-04-30 Q16 and I have both ufraw-batch and ufraw installed.
