The Ultimate Linux Shell Scripting Guide

Interpreting Commands

To fulfill its job as the interface between the user and the operating system kernel, a shell has to perform five different functions. These functions include interpreting commands, setting variables, enabling input/output redirection, enabling pipelines, and allowing customization of a user’s working environment. In this chapter, we’ll look at how bash and zsh interpret commands. As an added bonus, much of what we’ll cover in the next few chapters will also help you prepare for certain Linux certification exams, such as the Linux Professional Institute or CompTIA Linux+ exams.

Topics in this chapter include:

  • Understanding the structure of a command
  • Executing multiple commands at once
  • Running commands recursively
  • Understanding the command history
  • Escaping and quoting

To follow along, you can use pretty much any Linux distro that you desire, as long as it’s running with either bash or...

Key benefits

  • Embrace Bash, Zsh, and PowerShell across Linux, macOS, Unix
  • Seamlessly progress through chapters with conceptual explanations, illustrative examples, and immersive labs for hands-on skill development
  • Build real-world Linux administration scripts, enhancing your troubleshooting and management skills

Description

Embark on a comprehensive journey through command shells with this hands-on manual. While Bash is a Linux staple, Z shell and PowerShell are rising stars, applicable to Linux, macOS, and Unix. Progress seamlessly through chapters, each building on the last, creating a solid foundation. Learn through a unique approach: concepts, examples, and interactive labs. These labs, nearly a hundred strong, form the core of experiential learning, essential for script creation. Focusing on Linux commands and their scripting applications, this manual is universally relevant across Linux and select Unix-like systems. It goes beyond theory, offering practical scripts for real-world Linux administration. Scripts are designed for manageability, aiding learning and troubleshooting. The goal is to nurture the ability to craft intelligent, functional shell scripts. While centered on Bash, this book offers a peek into the future with Z Shell and PowerShell, expanding your skills and adaptability. This book is systematically structured and engaging so that it will guide you to master command shells, equipping you for real-world Linux challenges.

Who is this book for?

This book is for programmers who use the command line on Unix and Linux servers already, but don't write primarily in Bash. This book is ideal for programmers who've been using a scripting language such as Python, JavaScript or PHP, and would like to understand and use Bash more effectively. It’s also great for beginning programmers, who want to learn programming concepts.

What you will learn

  • Grasp the concept of shells and explore their diverse types for varied system interactions
  • Master redirection, pipes, and compound commands for efficient shell operations
  • Leverage text stream filters within scripts for dynamic data manipulation
  • Harness functions and build libraries to create modular and reusable shell scripts
  • Explore the basic programming constructs that apply to all programming languages
  • Engineer portable shell scripts, ensuring compatibility across diverse platforms beyond Linux

This book is probably one of, if not the most, comprehensive of all on the capabilities of scripting on Linux.It covers all the common scripting shells, even PowerShell (who knew it would be possible to run Microsoft's shell on Linux?!), methods of securing scripts, text manipulation, advanced scripting techniques including automation, shell configuration, error handling, piping and much more.I especially liked the chapters on image manipulations and creating user interfaces.Be aware that this book assumes you are scripting for an on-prem resident machine and it is probably the only shortcoming I can mention.

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date? Chevron down icon Chevron up icon

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready? Chevron down icon Chevron up icon

We'll let you know every time there has been an update to a course that you've bought in Early Access.
