How to Gracefully Close Jupyter Notebook

If you are running Jupyter Notebook on your local Mac/Windows device and you want to make sure that you did close the application gracefully, then here are a few ways to do it.

Option 1: Using the Menu Option

This is the the best and the ideal way to close a Notebook application.

Simply go to Menu: File and select Shut Down at the bottom.



You will get an alert asking if you really want o shutdown JupyterLab.



Once you click on "Shut Down" button, you will notice that the Command Line/Terminal that was running the Notebook server gets closed and so does the Browser tab.

Option 2: Using Command "jupyter notebook stop"

Open a new instance of your Terminal (CMD if on Windows) and run the below command.

jupyter notebook stop

You will notice that the Jupyter Notebook Server has stopped with logs as,

[I 2023-07-26 03:53:25.476 ServerApp] Shutting down on /api/shutdown request.
[I 2023-07-26 03:53:25.476 ServerApp] Shutting down 6 extensions

Option 3: The Quickest way - Control + C Twice

This is the quickest way to terminate a Notebook server, by pressing Control + C twice on the console.
