List running Jupyter notebooks and tokens

UPDATE

You can now just run jupyter notebook list in the terminal to get the running jupyter sessions with tokens.

Take care that you are within the right environment (conda, virtualenv etc.) otherwise the sessions will list without the associated tokens. Eg: The above reference screenshot is from the conda environment.

Old answer:

Run ipython and enter the following:

> ipython
[1] : system("jupyter" "notebook" "list")
Out[1]: 
['Currently running servers:','http://localhost:8895/token=067470c5ddsadc54153ghfjd817d15b5d5f5341e56b0dsad78a :: /u/user/dir']

If the notebook is running on a remote server, you will have to login in to that server first before running ipython.

One easy solution (that can save you time by avoiding opening a new terminal) is from the same terminal you are running the notebook to hit (ONLY ONCE!! - cause twice would kill the running server)

Ctrl + C  

By doing that the full link to your notebook will appear (along with the token!) and a prompt asking you to confirm shutting down. Just answer no (n and enter) or do nothing and after 5 seconds the operation will resume. In the meanwhile you would have been able to retrieve the link and/or the token you need.
