chennaji9 opened a new issue, #11328:
URL: https://github.com/apache/rocketmq/issues/11328
### Description
The operations-demo consumer
`example/src/main/java/org/apache/rocketmq/example/operation/Consumer.java`
prints its own usage with the wrong command label. Both help paths say
"producer":
```java
// Consumer.java:101 and :105
hf.printHelp("producer", options, true);
```
Running the consumer with `-h` (or with invalid arguments) prints `usage:
producer ...` followed by the *consumer* options (`consumerGroup`,
`subscription`, ...). The same file's sibling `Producer.java` correctly prints
`usage: producer`, so a user following both examples sees two programs both
claiming to be "producer".
### Expected behavior
The consumer should print `usage: consumer ...` for its own options —
`hf.printHelp("consumer", options, true)` in both places.
