Decrease JPG Quality

Ever wanted to save 100 jpg files with decreas­ing quality?

 
INPUTFILE=test.jpg
 
COUNT=100
while [ $COUNT -gt 0 ]
 do
    OUTPUTFILE=$COUNT.jpg
    convert -quality ${COUNT}% $INPUTFILE $OUTPUTFILE
    COUNT=`expr $COUNT - 1`
done
 
exit 0;

Made with bash and imagemag­ick.

These exam­ples are prob­a­bly super use­less. They per­form tasks that are nor­mally not part of design soft­ware, because they are use­less. But that’s the start­ing point. You can define on your own what is use­less! There is no pre-written workflow.
