Notebook: Checking by command line if Jupyter server is running

Created on 6 Dec 2016 · 9Comments · Source: jupyter/notebook

Sometimes we launched Jupyter and we crash it.
It would be good to have a command line to list of Jupyter kernel running like :
jupyter listall

It can be checked by checking the name 'jupyter' in the process list and terminate it by :
jupyter terminate id / all

There is a jupyter notebook list command for listing running notebooks. There isn't a corresponding terminate, though.

nbmanager is similar to what you want. It provides a GUI rather than a command line interface, but the module nbmanager.api is general purpose and could be reused to make command line UI.

sometimes, we manage Jupyter through SSH on remote server..... no GUI

For an SSH'd terminal, we can just run:

kill $(pgrep jupyter)

To kill terminals that we can't CTRL+C.

There is also now a jupyter notebook stop command that takes a port number and shuts down the corresponding notebook server.

From 5.1, you will also be able to shut a server down if you have HTTP access to it by making a POST request to /api/shutdown.

@takluyver Is jupyter notebook stop available in 5.0.0? I get a No such file or directory error:

$ jupyter notebook --version
5.0.0
$ jupyter notebook stop 8888
[C 10:02:38.220 NotebookApp] No such file or directory: /Users/jjpr/stop

Oops, sorry. It's new in 5.1, added by #2388.

This is giving parser error to me, any suggestions?
