Bash it Out - Bash Puzzle eBook for Experts

No, this book is not going to teach you bash scripting.

Instead, this book gives you 17 bash puzzles and you have to figure out why the script behaves differently or why the output of the script is not the intended one.

Of course the book discusses the solution to all the puzzles.

This is fun. This is challenging. If you think you know enough bash shell scripting, why not test your knowledge?
