Developer Cheat Sheets

This are my cheat sheets that I have compiled over the years. Tired of searching Google for the same things, I started adding the information here. As time went on, this list has grown. I use this almost everyday and this Gist is the first bookmark on my list for quick and easy access.

I recommend that you compile your own list of cheat sheets as typing out the commands has been super helpful in allowing me to retain the information longer.
