I don't log into bconsole for maybe a week at at time and when I do I'm
usually messing about with config settings.
I tend to always run 'auto on' as the first command but can sometimes have to
wait over 5 minutes for a week's worth of log entries to scroll up my screen.
Is there a way to limit the entries displayed to say the last 4 hours, or the
last 1000 lines?
