Yes that’s completely through but then again you need to temper with the default system settings 🙂

Yes you’re absolutely correct. What I meant by this post was just to give a basic overview on the current ways to improve a lame person who has access to the shell not to be able to delete their history. I know it’s far from superior 🙂

       –rwo, –report-warnings-only
              This option causes only warning messages to be displayed. This can be useful when rkhunter is run via cron. Other options may
              be used to force other items of information to be displayed.

       –sk, –skip-keypress
              When  the  –check command option is used, after certain sections of tests, the user will be prompted to press the return key
              in order to continue. This option disables that feature, and rkhunter will run until all the tests have completed.
