Move photos into subfolders (Year / Month)

[crazySwede]

I have lots of iphone photos in ONE folder. I would like to move them into 12 separate folders (Jan to Dec).

I tried to follow this post:
https://ingo-richter.io/post/2021/organize-a-folder-of-thousands-of-images-into-subfolders/

This is what happened: (I navigated via the terminal to the folder with the photos and wrote this command):
exiftool -d %Y/%m/%d "-directory<filemodifydate" "-directory<createdate" "-directory<datetimeoriginal"

But get this answer:
No file specified


What am I doing wrong?

The error is exactly what it says.  You didn't specify any files or directories.

If you look closely at the command in that article, you'll see a dot . at the very end.  On the command line, a dot by itself stands for the current directory.
