 The `hstream-kafka produce` command can be used to produce data to a topic in a interactive shell.
 ```sh
-hstream stream-kafka produce demo --separator "@" -i
+hstream-kafka produce demo --separator "@" -i
 ```
 - With the `--separator` option, you can specify the separator for key. The default separator is "@". Using the separator, you can assign a key to each record. Record with same key will be append into same partition of the topic.
 - Using `-i` option to enter the interactive mode.
 
 ```sh
 info@This is a info level log.
 warn@This is a warn level log.
-hello kafka!
+hello hstream!
 ```
