Automation of such across different platforms is not possible. For linux you would require so called cronjobs. So in essence all automation in Manager is triggered by the user. They send emails, they create reports, etc. Nothing is automated and as @Tut mentioned that is actually a very good thing. No hacker could trigger automated commands, so less chance they mess up with our precious accounts.
