sxcooler opened a new issue #4481: a little change needed of pulsar cli
URL: https://github.com/apache/pulsar/issues/4481
 
 
   **Is your feature request related to a problem? Please describe.**
   When I tried to use pulsar cli to test my code, send a json string to a topic, like this:
   ```
   ./pulsar-client produce my-topic --messages '{"appId":"test","userId":38,"phone":"13800138000","score":664}'
   ```
   But the default behavior of pulsar-client produce is use comma as separator to divide messages, so my json divided into several messages which I didn't want to, like this:
   ```
   19:06:03.742 [main] INFO  org.apache.pulsar.client.cli.PulsarClientTool - 4 messages successfully produced
   ```
   And I couldn't find any way to escape the comma(backslash / double backslash did not work).
   And after that I try to put the json into a file and use -f option, like:
   ```
   ./pulsar-client produce my-topic -f ./test.json
   ```
   And I got 
   ```
   java.nio.file.NoSuchFileException: ./test.json
   ```
   So I had to use the full path.
   
   **Describe the solution you'd like**
   * Do not use comma as default separator in cli, or at least tell users how to escape it in the command line help.
   * Support relative path in cli as other clis.
   
   **Describe alternatives you've considered**
   I can't imagine.
   
   **Additional context**
   none.
