Saves Jupyter Notebooks as .py and .html files automatically. Add to the ipython_notebook_config.py file of your associated profile.

post-save-hook.py

import os
from subprocess import check_call

def post_save(model, os_path, contents_manager):
    """post-save hook for converting notebooks to .py and .html files."""
    if model['type'] != 'notebook':
        return # only do this for notebooks
    d, fname = os.path.split(os_path)
    check_call(['jupyter', 'nbconvert', '--to', 'script', fname], cwd=d)
    check_call(['jupyter', 'nbconvert', '--to', 'html', fname], cwd=d)

c.FileContentsManager.post_save_hook = post_save

So it looks like this stackoverflow answer has the right way to go about this: https://stackoverflow.com/questions/29329667/ipython-notebook-script-deprecated-how-to-replace-with-post-save-hook

jupyter notebook --generate-config

and it will output the file name:

Writing default config to: /Users/user/.jupyter/jupyter_notebook_config.py

And that's the location that you'd like to edit. I've also tweaked the call to use jupyter instead of ipython.
