How to "Smart Sharpen," adaptive-sharpen not working

I'd like to be able to batch sharpen my photos, then just work on the ones that need more attention.

This really belongs on SuperUser i think as it relates more to general purpose scripting as opposed to programming... However, if youre *nix you could do the following with a bash script:

for f in /path/to/images/*; \
do echo "Sharpening $f file.." \
&& OUTPUT_FILE="sharpened.`basename $f`" \
&& echo "Output to $OUTPUT_FILE" \
&& convert $f OPTIONS $OUTPUT_FILE; \
done

OPTIONS would be all your options for the convert utility. This also assumes all /path/to/images ONLY contains image files convert can use and not directories or other types of files. You could modify it to be more smart if you wanted but youre on your own for that :-) Additionally, this will put the output files in whatever directory youre in, but you could easily supply a full path as the part of the $OUTPUT_FILE variable.
