How to resize or scale a list of images on linux

Here is a simple but powerful command when you got several images that you want to shrink:

mogrify -scale 50% *.jpg

This will reduce all the images by 50%

Or if you just want to reduce one image to 200x200 pixels for example:

convert -scale 200x200 image.jpg image_small.jpg
