How to Learn Bash: Best Courses, Books, and Resources

Karen Schwarze - October 06, 2022

Think of the last time you created a new file or navigated to a folder on your computer. You probably used a mouse or touchpad to do this, clicking until you made the new file or got inside the right folder. This is one way you can get around your computer system. Another great way to navigate your system is to learn Bash, a command line interface.

A command line interface (also known as a CLI or shell) is a screen on your computer through which you can communicate with your operating system. By entering a series of commands, you can quickly and easily manipulate files without using a mouse or touchpad.

That may not sound very exciting; after all, perhaps on a typical day, you aren’t opening that many files on your computer. However, as you continue in your tech career journey, you may need to manage more files and perform actions on those files quickly.

What Is Bash?

As mentioned, Bash is a type of CLI that you can use on your computer. We also say that we are “running Bash shell scripts” or use the term “Bash scripting language.” The commands that we write in Bash are “Bash commands.” You may see Bash referred to as both an interface and a programming language.

Bash runs on Unix-like operating systems. If you have ever looked at a system and wondered, “What is Bash?” and “Why is it loaded on my device?” it is likely due to the fact that it is a device that uses a Unix-like operating system.

A Unix-like operating system behaves similarly to a Unix system, which follows a set of standards called Single UNIX Specification. Linux, Android, macOS, and PlayStation 3 and 4 system software are all considered Unix-like.

If you have a macOS or Linux-based operating system, there is a good chance that you already have Bash installed on your computer. If you have a Windows operating system, you likely don’t have Bash installed, as Windows is not a “Unix-like” operating system.

However, Windows users often install something called Git Bash , a package that includes Git and Bash. Git is a version control system used for tracking changes in a set of files. It is often used by developers for coordinating projects.

Just as a web browser functions as a GUI (Graphical User Interface) so that you can access websites on the Internet, so does a CLI such as Bash act as your portal for interacting with all the files on your computer. With Bash, you can also run programs, monitor your operating system, view logs (files that contain information about your operating system and usage), and configure servers.

What Is a Bash Script?

If you are new to the world of Bash, you may be wondering, what is Bash scripting? Bash scripting is a series of commands created within a plain text file. These commands combine common commands and more advanced conditional statements to run systems. Anything that experienced users can type into a command line can be made into a simple Bash script.

Why Learn Bash?

Many data scientists and technical experts alike often ask, “Why learn Bash programming?” Bash is a skill that is used to make data scientists, software engineers, and statistical programming professionals more flexible.

Flexibility is key in any job or role, especially when it comes to technology. Additionally, it is important to learn Bash because it is a highly sought-after skill in the technology market. Stay employable and adapt by learning Bash . If these reasons alone do not answer the question, “Why use Bash?” then continue reading to learn the top reasons to learn Bash below.

Top Reasons to Learn Bash

  1. The Linux command language interpreter family Bash and Shell are extremely popular in tech. Jobs that use these languages pay very well and are revered in the tech community.
  2. Bash terminal commands allow users to create simple scripts that pull the same type of data, the same way, every day. This means the data quality and formatting are identical, making it more reputable and reliable for the user and their organization.
  3. Command line editing and scripting are required when dealing with the cloud. This is because these scripts are needed to move data to and from the cloud to access them in an efficient and cost-effective manner.

What Is Bash Used For?

Bash is a great CLI that can be used in numerous different ways. Many data scientists often use it as a scripting tutorial for new colleagues, to expedite common tasks, and to create custom commands. Learning Bash allows you to be more flexible when working with data. Below are more examples that illustrate why Bash is a powerful tool:

  • Expedite tasks. Using a CLI like Bash saves you time as a programmer. Instead of clicking through multiple applications and folders on your computer to find a file, you can use the command line to write just a few lines of commands to pull up the files you need. This is especially helpful if you are managing many files of code on your computer as a developer.
  • Write scripts for frequent tasks. In Bash, you can create a script that encapsulates a list of commands. If you have used a language like Python (another scripting language), you have probably written commands and then compressed those commands into a single function . In Bash, you can do something similar: Instead of writing a list of commands to perform a task, you can write a script that encapsulates that list of commands, so you can type just one command instead of many.
  • Use for system administration . Using Bash scripting, you can learn how much memory and space you have available, check your log to see what actions your system has recently performed, and see what happened when your system booted up. You can also troubleshoot system processes, such as applications, and kill an application that is malfunctioning. With Bash, you can do things like writing a script to check a new user’s desired username against existing usernames to see if the username is already taken.

Learning to navigate your computer this way may be intimidating initially if you are used to only using applications. But once you get the hang of it, you may find that you prefer using your computer’s CLI for opening files over using web applications.

Learning Bash

If your goal is to become a web developer, it’s a good idea to learn Bash (or Git Bash if you have a Windows operating system). Many programmers choose to navigate their computers using Bash or another command line interface. If you are at least familiar with Bash, you can communicate about this technology with other developers you work with. Using Bash or another CLI can speed up the development process, increasing your productivity, an advantage whether you are an employee at a company or doing freelancing or consulting work.

Not only is learning Bash a good idea for your own workflow, but it’s also an in-demand skill. As of this writing, on Not only is learning Bash a good idea for your own workflow, but it’s also an in-demand skill. As of this writing, on LinkedIn, there are over 14,000 job postings for roles in the United States that mention Bash. These roles include technical writer, DevOps software development engineer, cloud architect, and data analyst. Glassdoor lists over 9,000 roles that mention Bash. As you learn Bash, you can make yourself more marketable for a variety of roles in technology.

Let’s dig into the details of learning Bash.

How Long Does It Take to Learn Bash?

It will take you just one to two days to start writing your own basic scripts. However, just like programming languages, the Bash syntax has components like variables, loops, logic, and conditional expressions.

Understanding the complexity of learning Bash may lead you to ask, “How long does it take to learn Bash?” You will need to plan for the time commitment involved in learning Bash. It will take you three to four weeks to learn how to use these components to write complex scripts , command substitutions, and conditional statements, assuming you spend one to two hours practicing.

DepenDepending on your experience with other command line interfaces and scripting languages (like Python or Perl), you may be able to pick up Bash even more quickly.

How to Learn Bash: Step-by-Step

When it comes to learning Bash, you should choose a process that fits the way you learn. Some developers prefer to immerse themselves in information about a topic before trying it out themselves, while others like to learn just enough to get started.

Here are some “big-picture” guidelines to follow to better understand how to learn Bash:

Find Out Your Operating System

You may already have Bash installed on your computer if it is a Unix-like operating system, such as a macOS or Linux. It is important to note that if you are using Windows, you will need to install Git Bash in order to use Bash. This is because basic shell programming and Bash scripting cannot occur on operating systems that are not Unix-like.

Understand Command Line Interfaces

Because Bash is a type of command line interface, it’s a good idea to understand the general purpose and function of a CLI. Think about what some of the advantages of navigating around your computer using a CLI might be instead of having to click inside different applications and folders. When you’re using a CLI, you are interacting with the files on your computer, so it’s important to know the basics to avoid making unwanted changes or overwriting files.

Write Scripts

Try writing your own scripts. If you are on Windows, it’s a great idea to follow a tutorial like this one from Traversy Media about how to install and use Git Bash and get started writing scripts. If you have a Unix-like operating system, check out this tutorial from BlondieBytes .
