Zhong Wang commented on IOTDB-1664:
-----------------------------------
For POSIX systems, Jline provides a signal handling interface from Jline3. So
we may have to the sun.misc.SignalHandler directly to register signal handlers.
For non-POSIX systems like windows, I googled a little bit and found an
official document of handling windows:
https://docs.oracle.com/javase/10/troubleshoot/handle-signals-and-exceptions.htm#JSTGD348
And here is an example of exiting gracefully in windows:

> CLI quits with ctrl-D instead of ctrl-C

> URL: https://issues.apache.org/jira/browse/IOTDB-1664
> Project: Apache IoTDB
> Issue Type: Improvement
> Components: Client/CLI
> Reporter: Zhong Wang
> Priority: Major
> Labels: easy-fix
> Original Estimate: 24h
> Remaining Estimate: 24h

> Users of shell or command line tools like IPython tend to use ctrl-C to clear
> the current input buffer and use ctrl-D to exit the shell.
>
> It is easy to achieve, but can greatly improve the user experience. People
> won't frequently exit the CLI by accident anymore.
