Cloning RaspberryPi SD Cards

This is the best clone tool I’ve found, and used.

For what I want I just use the command: $ rpi-clone sda
This clones the current bootable SD Card to the SD Card in the USB port.

nginx – basics

This is a quick aid based on the Raspberry Pi documentation.

Some basic commands are:

sudo nginx -s reload
sudo nano /etc/nginx/nginx.conf
systemctl status nginx.service
