About the Book
The book heavily leans on examples and exercises to help you get comfortable with using Ruby from the command line. It is recommended that you manually type each example and experiment with them.
Prerequisites: You should be comfortable with programming basics and have prior experience working with Ruby. You should know concepts like blocks, be familiar with string/array/hash/enumerable methods, regular expressions etc. You should also have prior experience working with command line and bash shell and be familiar with concepts like file redirection, command pipeline and so on.
Visit https://github.com/learnbyexample/learn_ruby_oneliners for code snippets and exercise files. The repo also has solutions for exercises.
This Ruby one-liners cookbook is incredible. Pretty mind boggling all the stuff you can do.

About the Author
Sundeep Agarwal is a lazy being who prefers to work just enough to support his modest lifestyle. He accumulated vast wealth working as a Design Engineer at Analog Devices and retired from the corporate world at the ripe age of twenty-eight. Unfortunately, he squandered his savings within a few years and had to scramble trying to earn a living. Against all odds, selling programming ebooks saved his lazy self from having to look for a job again. He can now afford all the fantasy ebooks he wants to read and spends unhealthy amount of time browsing the internet.
When the creative muse strikes, he can be found working on yet another programming ebook (which invariably ends up having at least one example with regular expressions). Researching materials for his ebooks and everyday social media usage drowned his bookmarks, so he maintains curated resource lists for sanity sake. He is thankful for free learning resources and open source tools. His own contributions can be found at https://github.com/learnbyexample.
