Julia Arch Linux - Shell-Bash

Introduction

This article will provide an introduction to using the programming language Julia on the Arch Linux operating system through the command line interface (CLI) using Shell-Bash.

Julia is a high-level, high-performance dynamic programming language designed for numerical and scientific computing. Arch Linux is a lightweight and flexible Linux distribution known for its simplicity and customizability. Shell-Bash is a popular command line interface for interacting with the operating system and running scripts.

Installing Julia on Arch Linux

To install Julia on Arch Linux, open a terminal and enter the following command:

sudo pacman -S julia

This will install the latest version of Julia available in the Arch Linux repositories.

Running Julia on Shell-Bash

Once Julia is installed, you can start it by entering the following command in the terminal:

julia

This will bring up the Julia REPL (Read-Eval-Print Loop), which is an interactive prompt where you can enter Julia code and see the results immediately.

To exit the REPL, simply enter the following command:

exit()

Writing Julia Programs in Shell-Bash

Julia programs can be written in any text editor and saved with the ".jl" extension. To run a Julia program in Shell-Bash, navigate to the directory where the program is located and enter the following command:

julia your_program.jl

This will execute the program in the Julia environment.

Using Packages in Julia

Julia has a package manager called "Pkg" that can be used to install and manage third-party packages. To use a package in a Julia program, first install the package using the following command:

] add package_name

This will download and install the package in the Julia environment. Then, in your Julia program, add the following line at the beginning of your script:

using package_name

This will load the package and make its functions and types available in your program.

Conclusion

In this article, we have covered the basics of using Julia on the Arch Linux operating system through the Shell-Bash command line interface. We have discussed how to install Julia on Arch Linux, run Julia in the REPL, write Julia programs, and use third-party packages in Julia. With this knowledge, you can start exploring the features and capabilities of Julia and using it for scientific and numerical computing.
