I've found DOS stuff runs better in DOSbox DOSbox is an emulator, I would like to reach near native speed. My ultimate goal is to write a bash script that calls DeflOpt as if it was a unix tool. #!/bin/bash IFS="$(echo -e "\n\r")" for currentfile in $* do printf "Working on %s ======\\n" $(basename $currentfile) printf "Original size: %8d bytes\\n" $(stat -f "%z" "$currentfile") (which optipng && optipng -o7 "$currentfile") > /dev/null (which advpng && advpng -z4 "$currentfile") > /dev/null (which pngout && pngout -y -ks "$currentfile") > /dev/null (which deflopt && deflopt "$currentfile") > /dev/null printf "Final size: %8d bytes\\n" $(stat -f "%z" "$currentfile") done
