本文以关闭 jupyter notebook 为例，讲述常见的几种 kill 方法。

1. 使用应用自带的arg选项，例如stop

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.)

2. pkill

2.1. use kill with pgrep

echo 'alias quitjupyter="kill $(pgrep jupyter)"' >> ~/.bashrc

2.2. or directly, pkill

pkill jupyter

2.3. killall

2.4. 通过端口查询PID

1. 我们可以使用 lsof -n -i4TCP:8888 来查询进程号：

   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.
   

2. 或者，直接使用 fuser 指令：

   • 查询： fuser -v -k -i -n tcp 31888
   • 终结进程： fuesr -k 31888/tcp
