 \fB\-\-warnings <batch|off>\fR The warnings parameter determines how testssl\.sh will deal with situations where user input will normally be necessary\. There are a couple of options here\. \fBbatch\fR doesn\'t wait for a confirming keypress\. This is automatically being chosen for mass testing (\fB\-\-file\fR)\. \fB\-false\fR just skips the warning AND the confirmation\. Please note that there are conflicts where testssl\.sh will still ask for confirmation\. Those are ones which would have a drastic impact on the results\. The same can be achieved by setting the environment variable \fBWARNINGS\fR\.
