The function of 'kafka-console-consumer.sh' is to read messages from a Kafka topic and display them on the console. This command-line tool allows users to connect to a specific Kafka topic and consume the messages being produced to that topic in real time. It is especially useful for debugging and monitoring the flow of messages through Kafka, as it provides a straightforward way to see the data being passed without needing to write custom consumer applications.

By using this tool, developers and system administrators can easily verify that the message production is working correctly, check the data integrity, and observe message formats. The utility takes various parameters that allow users to define specific topics, offsets, and other configurations to customize their consumption experience according to their needs.

In contrast, other options pertain to different functionalities, such as sending messages, deleting topics, or creating consumers, which are handled by other specific commands within the Kafka ecosystem.
