Julia 1.0 Programming Cookbook

By: Bogumił Kamiński, Przemysław Szufel

Overview of this book

Julia, with its dynamic nature and high-performance, provides comparatively minimal time for the development of computational models with easy-to-maintain computational code. This book will be your solution-based guide as it will take you through different programming aspects with Julia. Starting with the new features of Julia 1.0, each recipe addresses a specific problem, providing a solution and explaining how it works. You will work with the powerful Julia tools and data structures along with the most popular Julia packages. You will learn to create vectors, handle variables, and work with functions. You will be introduced to various recipes for numerical computing, distributed computing, and achieving high performance. You will see how to optimize data science programs with parallel computing and memory allocation. We will look into more advanced concepts such as metaprogramming and functional programming. Finally, you will learn how to tackle issues while working with databases and data processing, and will learn about on data science problems, data modeling, data analysis, data manipulation, parallel processing, and cloud computing with Julia. By the end of the book, you will have acquired the skills to work more effectively with your data

Running Julia as a background process

In this recipe, you will learn how to run Julia as a background process, and pass commands to it using pipes.

We would like to thank Charles Duffy for ideas that helped to improve this recipe, as discussed at

Getting ready

For this example to work, you need to run it under bash.

This would be the default under Linux. If you are on Windows, you can use the bash that is shipped with a Git installation.


In the GitHub repository for this recipe, you will find the commands.txt file, which contains the presented sequence of shell and Julia commands.

Now, open your favorite terminal to execute the commands and switch to an empty folder.



How to do it...

In this recipe, you will start a Julia process in the background and then pass commands to it via a named pipe:

  1. First, create a named pipe using the mkfifo command. We will call it pipe:
$ mkfifo pipe
  1. Check that a file...
