>             Project: Kafka
>          Issue Type: Bug
>          Components: tools
>    Affects Versions: 2.6.0

> The prompt introduced in KAFKA-2955 may be indeed helpful when a user enters messages manually but when the messages are read from a file, it's not helpful and may be really annoying.
> h5. Steps to reproduce
>  # Create a file with a decent number of messages (e.g. 80,000 in my case)
>  # Start console producer and forward the file contents to its STDIN:
> {noformat}
> $ kafka-console-producer --broker-list b1,b2,b3 --topic test < messages.txt
> >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> ... >>>>>>>>>>>>>>
> {noformat}
> For each message the producer reads from the file, there's one > displayed polluting the output.
> h5. Expected behavior:
>  # If the producer can detect that the input stream is a TTY, it should not display the prompt.
>  # Ideally, there should be a configuration parameter to disable this explicitly.
