How to stop mogrify -format from making new images?

[acoustic7]

Hello all, I have a simple question.

I'm using the command:

Code: Select all

mogrify -format pgm *.png

to convert a folder of pngs to pgms. While I understand why it does it, morgify just makes a new image in the different format. I have a bunch of images and don't want to keep doubling the size of the directory. Is there a way to make mogrify just replace the image? If not, is there a way to delete all of a type of image (i.e. png) once i'm done mogrifying it all?

Thanks!!
