How to batch resize images in Ubuntu recursively within the terminal?

Question

I have multiple images stored in a set of organized folders. I need to re-size those images to a specific percentage recursively from their parent directory

Answer 1

You can also use

sudo apt-get install nautilus-image-converter

But this only works for image in the current folder. You just install and then right click on an image or multiple ones and choose the size you want and that's it.

I believe this also uses imagemagick.
