rotating hardcopy logs

[Eric Smith]

Hi

I want to absolutely be sure of never losing any data I enter into a terminal.
A security feature like hardcaopy log <command> H
would be perfect but say I want to curtail the size of this file to have
at any time only the last n kB, what would be a good (elegant) way to do this?
Not sure logrotate is really attractive.

Thanks
