If you run jupyter in the background like me   jupyter notebook  amp  gt   dev null  amp    Then to exit jupyter completely  instead of Ctl-C  make an alias command   echo  alias quitjupyter  kill   pgrep jupyter     gt  gt     bashrc   Restart your terminal  Kill all jupyter instances   quitjupyter   Note  use double quotes inside of single quotes as shown above   The other way around will evaluate the expression before writing it to your  bashrc  you want to write the command itself not  kill 1430  or whatever process number may be associated with a current jupyter instance    Of course you can use any alias you wish   I actually use  qjup    echo  alias qjup  kill   pgrep jupyter     gt  gt     bashrc   Restart your terminal  Kill all jupyter instances   qjup

Option 1 Open a different console and run jupyter notebook stop  PORT   The default  PORT  is 8888  so  assuming that Jupyter Notebooks is running on port 8888  just run jupyter notebook stop  If it is on port 9000  then jupyter notebook stop 9000   Option 2  Source   Check runtime folder location jupyter --paths   Remove all files in the runtime folder rm -r  RUNTIME FOLDER PATH      Use top to find any Jupyter Notebook running processes left and if so kill their PID  top   grep jupyter  amp  kill  PID     One can boilt it down to TARGET PORT 8888 kill -9   lsof -n -i4TCP  TARGET PORT   cut -f 2 -d  quot   quot     Note  If one wants to launch one s Notebook on a specific IP Port jupyter notebook --ip  ADD IP  --port  ADD PORT  --allow-root  amp

For those of you who work on a remote computer with ssh  and maintain a Jupyter notebook server inside a tmux session  then after you exit the Jupyter notebook  you also have to close the pane that was used to maintain your Jupyter notebook server  Otherwise  it could cause issues when you try to log out from the ssh

These commands worked for me   jupyter notebook list   shows the running notebooks and their port-numbers                          for instance  8080  lsof -n -i4TCP  port-number    shows PID  kill -9  PID    kill the process    This answer was adapted from here

The best way now is to use the  quot Quit quot  button that is just to the left of the  quot Logout quot  button  I have to admit that I do not understand the utility of the Logout button  However  I am glad that they have added the exceedingly useful Quit button

Linux  Ubuntu 14 04    As mentioned  try to kill ipython notebook processes properly by first going to the  running  tab in your ipynb jupyter browser session  and then check open terminals on your console and shut down with ctrl-c  The latter should be avoided if possible   If you run an ipython notebook list and continue to see running ipython servers at different ports  make note of which ports the existing notebooks are being served to  Then shut down your TCP ports    fuser -k  port   tcp    I m not sure if there are other risks involved with doing this  If so  let me know

Environment    My OS is Ubuntu 16 04 and jupyter is 4 3 0   Method    First  i logged out jupyter at its homepage on browser the logout button is at top-right   Second  type in Ctrl   C in your terminal and it shows       I 15 59 48 407 NotebookApp interrupted Serving notebooks from local   directory   home Username 0 active kernels       The Jupyter Notebook is running at    http   localhost 8888  token a572c743dfb73eee28538f9a181bf4d9ad412b19fbb96c82      Shutdown this notebook server  y  n      Last step  type in y within 5 sec  and if it shows       C 15 59 50 407 NotebookApp  Shutdown confirmed    I 15 59 50 408   NotebookApp  Shutting down kernels   Congrats  You close your jupyter successfully

There isn t currently a better way to do it than Ctrl C in the terminal   We re thinking about how to have an explicit shutdown  but there s some tension between the notebook as a single-user application  where the user is free to stop it  and as a multi-user server  where only an admin should be able to stop it  We haven t quite worked out how to handle the differences yet    For future readers  this is the situation with 0 12 released and 0 13 in development    Update December 2017  The IPython Notebook has become the Jupyter Notebook  A recent version has added a jupyter notebook stop shell 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    A config option to automatically shut down the server if you don t use it for a specified time  A button in the user interface to shut the server down   We know it s a bit crazy that it has taken this long  Changing UI is controversial

First step is to save all open notebooks  And then think about shutting down your running Jupyter Notebook  You can use this simple command    jupyter notebook stop  Shutting down server on port 8888      Which also takes the port number as argument and you can shut down the jupyter notebook gracefully  For eg  jupyter notebook stop 8889  Shutting down server on port 8889      Additionally to know your current jupyter instance running  check below command  shell gt  jupyter notebook list  Currently running servers  http   localhost 8888  token ef12021898c435f865ec706de98632     Users username jupyter-notebooks   code

I am copy pasting from the Jupyter IPython Notebook Quick Start Guide Documentation  released on Feb 13  2018  http   jupyter-notebook-beginner-guide readthedocs io en latest execute html  1 3 3 Close a notebook  kernel shut down When a notebook is opened  its    computational engine     called the kernel  is automatically started  Closing the notebook browser tab  will not shut down the kernel  instead the kernel will keep running until is explicitly shut down  To shut down a kernel  go to the associated notebook and click on menu File -  Close and Halt  Alternatively  the Notebook Dashboard has a tab named Running that shows all the running notebooks  i e  kernels  and allows shutting them down  by clicking on a Shutdown button    Summary  First close and halt the notebooks running   1 3 2 Shut down the Jupyter Notebook App Closing the browser  or the tab  will not close the Jupyter Notebook App  To completely shut it down you need to close the associated terminal  In more detail  the Jupyter Notebook App is a server that appears in your browser at a default address  http   localhost 8888   Closing the browser will not shut down the server  You can reopen the previous address and the Jupyter Notebook App will be redisplayed  You can run many copies of the Jupyter Notebook App and they will show up at a similar address  only the number after          which is the port  will increment for each new copy   Since with a single Jupyter Notebook App you can already open many notebooks  we do not recommend running multiple copies of Jupyter  Notebook App   Summary  Second  quit the terminal from which you fired Jupyter

Actually  I believe there s a cleaner way than killing the process es  using kill or task manager   In the Jupyter Notebook Dashboard  the browser interface you see when you first launch  jupyter notebook    browse to the location of notebook files you have closed in the browser  but whose kernels may still be running   iPython Notebook files appear with a book icon  shown in green if it has a running kernel  or gray if the kernel is not running   Just select the tick box next to the running file  then click on the Shutdown button that appears above it   This will properly shut down the kernel associated with that specific notebook
