I have a large directory tree with many sub-folders and lots of images within each one. I found a script that applies watermark to all images within a directory, in-place, overwriting the original image. I'm looking for the best way to iterate trough all the folders and subfolders and run the "compose" command for each image on my linux server.
Here is the original script I found

#!/bin/bash

  You don't need that whole script to do that... find . -iname '*.jpg' -exec echo composite -dissolve 40% -gravity SouthEast -quality 100 /path/to/watermark -resize 100 {} {} ; Replace /path/to/watermark and 100 after -resize with your actual values and if you're happy with the result remove the echo in front of composite

The script already checks the directory for image files, but if you want to adjust it to go through all your directories and not prompt you for each one, you might as well just rewrite it. Something like:

#!/bin/bash



WM=$HOME/public_html/image/catalog/logo-website/watermark.png  # This is the path to your watermark image

SCALE=100                          # This sets the scale % of your watermark image

STARTDIR="/home/whatever/images"   # This is the directory to start in



for imagedir in $( find $STARTDIR -type d )

do

  echo "Running in $imagedir ..."

  cd $imagedir

  file -i * | grep image | awk -F':' '{ print $1 }' | while read IMAGE

  do

    echo "Watermarking $IMAGE"

    composite -dissolve 40% -gravity SouthEast -quality 100 ( $WM -resize $SCALE% ) "$IMAGE" "$IMAGE"

  done
