You are not alone in these desires :) Great, thanks :)

Nope, that fits the definition of "redirecting everything into the file". I would guess you'd rather want to tee the console output to file to get the desired effect. Although, we will certainly consider this when reworking the output formatters. OK, also one point more in favor of not redirecting everything: the report contains the logs of the code under tests, which breaks the CSV syntax for example. So IMHO it would be better if the --output option just meant "report file" with only JMH output. As you said, users can use shell redirections if they want to redirect everything.

Thanks, -Aleksey. Cheers, Julien
