  But then again, "crop these two hundred photos to remove the white margin", certainly is. It would be extremely painful to do so without the command line. Some of us are such nerds, that we even crop a single photo with command line utils. Something like this: imcrop `imrectangle in.png` in.png out.png where imrectangle is a program that opens the image in a window and allows you to select a rectangle, whose coordinates are printed to stdout upon closing the window. You can even put this line on a shell script that you can call as viscrop in.png out.png and does the whole deed. With some care, it can even work on pipes: cat in.png | viscrop > out.png
