Paul; At 3:00, you mention sudo shutdown -h now -r. Is there a difference from sudo reboot? I know this video is a year old, but I'm new to Raspberry Pi, Linux. Going back and watching those videos, learning the operating system and diligently documenting steps as I go.

I chose the Pi Zero W for my first Pi because of it's size and "wireless". Was referred to it for running Mosquitto MQTT server to augment my Wemos D1 Mini project.

Thanks again for your awesome tutorials!

Great Mr McWhorter! Very clear examples! A couple of questions, if possible:

(1) Is it possible to schedule via Terminal Rpi's shutdown after 25 minutes and reboot at specifict time (at 14:00)?
Example: sudo shutdown -h +25 -r 14:00
(2) Is it possible to schedule via Cron Rpi's shutdown (at 18:25) and reboot at specific time (at 23:00)?
Example: 25 18 * * * sudo shutdown -h -r 23:00

Thanks in advance for your reply.

Hello Mr. McWhorter! What if you experience a sudden power fluctuation or something? What to do then?

Whats if we use
sudo shutdown -P now. ???

So I have a cable with a power switch on it and after using (I think) "sudo shutdown now", it turned off but the power light is still on. Is it safe to flip the switch to off?
