How do you check the login tokens for all running jupyter notebook instances?

Example: you have a notebook running in tmux or screen permanently, and login in remotely through ssh. Sometimes, particularly if you're logging in after a long time, the token is requested again in order to access the notebook session. How do you get hold of the token without having to kill and restart the notebook session with a new token?

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.
