Its a hacked together shell script. I wanted to learn shell scripting, but I should’ve probably programmed it in python.

But it basically does this:

1. scan pages as png via scanimage in gray scale
2. convert the image into a high contrast b/w one with image magick
3. sort pages if I have to combine two scans (front and back side)
4. create a single pdf of all the document pages via image magick
5. move pdf to the paperless folder

I won’t share it because it’s really ugly and some of the functionality can be done with paperless native, like combining the pages of two scans. Which would’ve been easier.
