Git Cheat Sheet

March 19, 2011 | Comments Off

After watching from the side lines for a few years as git gathered a following I finally made the switch out of necessity as a result of doing more projects in Ruby on Rails. The projects I work on are all hosted in the cloud (Heroku, Engine Yard, or directly on Amazon EC2). Many of the tools I use support direct deployment from git. So I now find myself migrating all of my projects from subversion to git.

I tend to write down a lot of notes as I learn a new technology or tool. The migration to git is no different. What is different is how GitHub (the hosted git solution I am using) makes it possible to record just about anything in what they call a gist. This is turning out to be a very useful tool for me. It is a great place to store little bits of code or notes.
