Data Science at the Command Line Second Edition

In this book, we’re going to obtain, scrub, explore, and model data—a lot of it. This book is not so much about how to become better at those data science tasks. There are already great resources available that discuss, for example, when to apply which statistical test or how data can best be visualized. Instead, this practical book aims to make you more efficient and productive by teaching you how to perform those data science tasks at the command line.

While this book discusses more than 90 command-line tools, it’s not the tools themselves that matter most. Some command-line tools have been around for a very long time, while others will be replaced by better ones. New command-line tools are being created even as you’re reading this. Over the years, I have discovered many amazing command-line tools. Unfortunately, some of them were discovered too late to be included in the book. In short, command-line tools come and go. But that’s OK.
