I have a folder containing many subfolders full of images. See attached image for example.
Basically I want to loop through them all and downsize the images so none are wider than 1024 pixels. They're all jpegs.
I'm aware of the SIPS commands i.e.
sips -Z 1024 *.png
However, that only works if all images are in the current directory.
How do I set it up to traverse through all subdirectories?
You can run it with find: find images/path -type f -name '*.png' -exec sips -Z 1024 {} \;
Find will search for files (-type f), with png extension (-name '*.png') inside 'images/path' directory and exec the command in parameter, replacing "{}" with the filename, you need to end the command with "\;".
find /images/path -type f -iname "*.jpg" -execdir convert {} -resize 1024x1024\> -quality 70 {} \;

find images/path -type f -name "*.jpg" -exec sips -Z 1024 -s format jpeg -s formatOptions 80 {} \;

-delete instead of -exec rm {} \; if you want just to remove files: find "FOLDER_NAME" -type f -name '*_16.png' -delete
I managed to change a small bash script which worked for me
#!/bin/bash
find "foldername" -type f | \
while read file ; do
echo "processing ${file}"
sips -Z 2000 ${file}
done
