You are about to embark on a little adventure. My aim is that, by the time you reach its end, you will have mastered some invaluable command line tools.
The adventure follows a twisted path, but it shouldn't take too long to complete. You will be challenged at times, but there are also some fun surprises in store.
Be sure to study the video tutorials carefully at each stage. When things get tough remember that this is just the awkward feeling of learning a new skill - embrace the complexity !
Before we begin you need to introduce yourself. What shall I call you ?
