Just found this snippet in one of my local snippet files. i think I got this from some blog…. but I can’t recall 🙁 anyhoo awesome little piece of code, generates thumbnails from all images in the dir its run from.

#!/bin/sh

make_thumbnail() {
    img=$1
    thumb=$(dirname "$1")/thumb-$(basename "$1")
    convert "$img" -thumbnail x100 "$thumb"
}

for pic in *.jpg
do
    make_thumbnail "$pic"
done
