Open notebooks from the command line
nbopen looks for the nearest running notebook server - if it finds one, it opens a web browser to that notebook. If not, it starts a new notebook server in that directory.
python3 -m pip install nbopen
To integrate with your file manager, so you can double click on notebooks to open them, run:
python3 -m nbopen.install_xdg
python3 -m nbopen.install_win
