How do I shutdown the jupyter server (ideally without having to search for the pid and then invoking kill)?

Starting from jupyter notebook version 5.1.0, the command

jupyter notebook stop <port number>

should shutdown the notebook server. If you don't enter a port, it defaults to 8888 as that is the default. To know on which ports the servers are currently running, you can do

jupyter notebook list

With jupyter notebook version 5.0, if it is running in the background of your terminal a solution is to do as @juanpa.arrivillaga wrote in the comments:


to see the jobs running in the background if there is only one and it is the jupyter notebook then


will bring it back to the foreground at which point you can kill it with ctrl-c. And if there are many processes in the background, for example, jobs returns

[1] Running firefox &

[2] Running jupyter notebook &

In a terminal you could run

pkill -f -1 jupyter*

Or I have found this to work when all else fails

sudo pkill -1 -f python

Furthermore no processes seem to have the name jupyter in the  Many times when running Jupyter notebooks I find myself wishing for a quick clean mechanism to cleanly shutdown &/or restart the server without having to go to the command window that it is running in and hit control-C and without the risk of not having saved and shutdown all kernals that may be running at the time.

Use kill -9 or kill -2 command. To find id of your process use ps aux.

Running the Notebook, How do I start the Notebook server without opening a browser? 08:58:24.417 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice​  A recent version has added a jupyter notebook stopshell command which will shut down a server running on that system. You can pass the port number at the command line if it's not the default port 8888. You can also use nbmanager, a desktop application which can show running servers and shut them down. Finally, we are working on adding:

In our case, the link to access the Jupyter Server would be as follows:  Ctrl-C is delivered to the terminal, where it will typically be translated into SIGINT. If the frontend (terminal emulator) is in Linux or Windows, Ctrl-Shift-C copies to the clipboard. Other platform copy shortcuts, such as Cmd-C on OS X and Ctrl-Insert on Linux, should work as normal.

Here you can find more detailed information if you want to. Shortcuts. As a developer, I like to use shortcuts and snippets as much as I can. They just make writing code a lot easier and faster. I like to follow one rule:

  • In a terminal use ps aux to view all running processes. If it is not in this list, it is not running. Then use kill with the PID of the process.
  • I can't even find the pid because no processes are named jupyter as mentionned. But in any case, I would like a more elegant way if possible.
  • If there are no processes named jupyter, then jupyter isn't running. I don't know what sort of answer you were expecting, in terms of "more elegant".
  • It is most definitely running because I can still access from the browser.
  • Also, you can always use jobs to see running background jobs. Then, use fg to put the job back in the foreground, and then you can use ctrl-c. If there are more than one, there will be a number, e.g. [2]+ Running jupyter notebook & then you use the number, e.g. fg 2, or just kill it directly kill %2
