rm [name]	Remove the specified file
rm *	Remove all files from the current working directory
rmdir [name]	Remove the empty directory [name] from the current working directory
sudo [command]	Superuser do. Execute [command] with elevated privileges (Allows you to do things you usually wouldn’t have access to)
sudo apt-get install [package]	Install a package
sudo apt-get update	Update the list of packages
sudo apt-get upgrade	Upgrade the installed packages – must be run after Sudo apt-get update
sudo chown pi:root [name]	Change the owner of the file [name] to user ‘pi’ and set the group to ‘root’
sudo raspi-config	Launch the Raspberry Pi configuration menu
sudo reboot	Safely restart your Pi
sudo shutdown -h now	Safely shutdown your Pi immediately
sudo su	Places you in the root directory with root user access – be careful with this!

tar -xvzf [name]	Extract the contents of the compressed file [name]
wget [uri]	Download the file found at [uri] on the internet
import RPi.GPIO as GPIO	Import the RPi.GPIO module into the python sketch
GPIO.setmode(GPIO.BCM)	Use Broadcom pin numbers (GPIO 14, GPIO 15 etc)
GPIO.setmode(GPIO.BOARD)	Use board pin numbers (4,5, 8 etc)
GPIO.getmode()	Returns current pin numbering mode (BCM, BOARD, or None)
GPIO.setup([pin number], GPIO.IN)	Set up the pin at [pin number] to be an input
GPIO.setup([pin number], GPIO.IN, pull_up_down=GPIO.PUD_DOWN)	Set up the pin at [pin number] to be an input with internal pull down resistance
GPIO.setup([pin number], GPIO.IN, pull_up_down=GPIO.PUD_UP)	Set up the pin at [pin number] to be an input with internal pull up resistance

GPIO.setup([pin number], GPIO.OUT, initial=1)	Set up the pin at [pin number] to be output with the initial value ‘1’
GPIO.output([pin number], 1)	Set [pin number]’s value to 1. Note that 1, GPIO.HIGH and True are the same thing
GPIO.output([pin number], 0)	Set [pin number]’s value to 0. Note that 0, GPIO.LOW and False are the same thing
i = GPIO.input([pin number])	Set the variable I to the value of [pin number]
if GPIO.input([pin number]):	Use the value of [pin number] as a boolean in the code
GPIO.cleanup()	Reset all GPIO pins (good practice to call before leaving any program)
