Course Description

Bash is a concise, superfast, and robust scripting language for data and file manipulation. It’s a vital skill for building analytics pipelines in the cloud, favored by Linux users to work with data stored across multiple files. In this course, we’ll guide you through the basics of Bash scripting. We begin with an introduction to Bash script structures, including inputting arguments and outputting results. You’ll then work through data structures, such as variables and arrays, and control statements, including loops and conditionals. You’ll then put what you’ve learned into practice, by creating your own Bash functions and scheduling automated scripts to run like clockwork with cron.

Great course, giving it a 5 star. Course slides are available. Hints on the side for every exercise. And what's best, an AI tool that helps explain things, like where and which part of your code is wrong. No need to go outside of DATACAMP platform.
