Hi, I see an interesting issue[1] about changing the CLI exiting command from the current ctrl-C to ctrl-D, which makes sense I think. I also found that the Influxdb 1.8.9 is using ctrl-D to exit the CLI as same as the mentioned IPython.
To implement this, I think it is necessary to upgrade jline2 to jline3, which is discussed in the issue[1]. Please let me know if there are other idea about it. Moreover, I find jline3 is already imported in CLI. Best, Haonan Hou [1] https://issues.apache.org/jira/browse/IOTDB-1664
