Quiz: your first commands and Linux components

One correct answer

ps in your terminal listed two lines — bash and ps — while systemctl is-active nginx printed active. Why is nginx not on the ps list?

• A It is a service with no terminal, and ps lists the terminal's processes.
• B nginx runs inside the bash process and is not shown on its own.
• C nginx shows up in ps when a request reaches the site.
• D The service has already stopped, and systemctl showed a stale state.
