Introduction

The unix command line, although invented decades ago, is an amazing environment for efficiently performing tedious but essential data science tasks. By combining small, powerful, command-line tools (like parallel, jq, and csvkit), you can quickly scrub and explore your data and hack together prototypes.

This hands-on workshop is based on the O’Reilly book Data Science at the Command Line, written by our CEO Jeroen Janssens. You’ll learn how to build fast data pipelines, how to leverage R and Python at the command line, and how to quickly visualise data. No prior knowledge about the unix command line is required.

By the end of this workshop you will have a solid understanding of …

Introduction

The unix command line, although invented decades ago, is an amazing environment for efficiently performing tedious but essential data science tasks. By combining small, powerful, command-line tools (like parallel, jq, and csvkit), you can quickly scrub and explore your data and hack together prototypes.

This hands-on workshop is based on the O’Reilly book Data Science at the Command Line, written by our CEO Jeroen Janssens. You’ll learn how to build fast data pipelines, how to leverage R and Python at the command line, and how to quickly visualise data. No prior knowledge about the unix command line is required.

By the end of this workshop you will have a solid understanding of how to integrate the command line in your data science workflow. Even if you’re already comfortable processing data with, for example, R or Python, being able to also leverage the power of the command line can make you a more effective and efficient data scientist.

What you’ll learn

  • Automate tedious tasks
  • Parallelise and distribute your tasks to multiple cores and machines
  • Convert your existing code to reusable command-line tools
  • Easily inspect, transform, and visualise data
  • Apply a variety of supervised and unsupervised machine learning algorithms

  • Downloading data from the Internet and accessing APIs using curl
  • Transforming data with filters such as cut, paste, grep, and sed
  • Processing other data formats efficiently
    • JSON with jq
    • CSV with csvkit
    • HTML with pup
    • XML with xmlstarlet

Day 2:

  • Running R from the command line
  • Visualising data from the command line
    • Scatter plot
    • Histogram
    • Bar chart
    • Geographic visualisation

Testimonials

“Great workshop! Very well done and very useful information delivered in an excellent and interactive manner. Jeroen anticipated very well on the different knowledge levels within the group. I would highly recommend the Data Science at the Command Line workshop to anyone that is interested in either kickstarting their command-line experiences or improving their data science with Unix power tools.”

–Sanne Bouwman, Data Scientist, Teradata

“As a seasoned UNIX command line adept, I didn’t expect to learn much from a Data Science at the Command Line workshop. I was wrong! Over the years, many new tools have become available that I didn’t know about, and that can be combined with traditional tools in new ways.

Since attending the workshop, I have been able to simplify and improve the efficiency of many of the scripts I use on a daily basis. Recommended for anyone working from the command line, newbies and ninjas alike!“

–Joost van Dijk, Manager Middleware Services, SURFnet

“Besides demonstrating a good knowledge and experience in command-line tools for data science, the instructor had very good training skills, clear communication, and managed to adapt the level of the training to the level of the audience, which is not always easy!”

–Marc Canaleta, CTO, Social Point
