downloads all files or files that contain a given substring from the remarkable 2 tablet

remarkable-downloader.py

#!/usr/bin/python3
# @deadjakk
# to use: just plug in remarkable 2 tablet, go to settings > storage > enable web application
# then run
# python3 ./remarkable-downloader.py                # this downloads literally everything as a pdf
# alternatively, adding a word as an argument will only download files with that word in the name
# python3 ./remarkable-downloader.py "math-notes"    # this downloads math-notes.pdf 

# this could be cleaner... but I no longer use/have a remarkable 2 so I probably won't bother

# probably need to run these as well:
# pip install glob
# pip install requests
