A super quick tip this. The other day I needded to find images bigger than a given width on the New Internationalist website. The quickest way I could think of to do this was to use find to locate all the files and combine that with ImageMagick’s identify command. And finally to pipe that to sort to make sure the list came out in size order. Then I could scroll down to the cutoff size.
Here is the final command I used. $ find . -iname *jpg -exec identify -format "%w: %f" {} \; | sort -rn
Job done.
