When you see three numbers like 0.45 0.30 0.18 in top or uptime,
that is the load-average (LA). It is the most quoted and least
understood indicator of system health. In this lesson you work out what
they mean, how to read them against the CPU count, and why a high LA does
not always mean the CPU is overloaded.

System metrics are under control. Next you set up your own workspace: PATH, environment variables, aliases, and history. This is about not typing the same thing a hundred times.
