PowerShell Practitioner acquaints readers with fundamental programming knowledge first. You will be sufficiently armed to approach problems programmatically, better understand and tackle real-world business challenges, develop and implement business solutions, and iteratively enhance existing solutions to help drive CPI (continuous process improvement). PowerShell Practitioner is a comprehensive guide spanning just under 200 pages; a non-fiction work geared toward tech-centric individuals and seasoned IT professionals interested in programming or a desire to sharpen existing skill sets. With almost a decade of cumulative experience in Information Technology, I commit to personally leading you through the fundamentals and popular misconceptions of entry-level programming and scripting.

Programming is the act of creating instructions for a computer to follow. These instructions, also known as code, are written in a specific programming language (of which there are many). For instance, think of it like giving step-by-step instructions on how to make a PB&J sandwich. Just as one would detail the steps for spreading peanut butter on one slice of bread and jelly on another, programmers detail steps for the computer to perform tasks. These instructions are used to tell a computer to perform a wide variety of tasks, from simple calculations to complex software. Some of the most popular programming languages today include Python, Java, C++, and jаvascript. Nowadays, you’ll interact with programming in almost every aspect of daily life, from the apps on your phone to the websites you visit to the cars you drive. Writing code is a field that is constantly evolving and offers endless opportunities for creativity and innovation. Learning to code will allow you to bring your ideas to life. Additionally, it’s a highly valuable skill to have in today's job market.

Scripting is the act of writing small scripts, or programs, that can automate tasks. Scripting can help you automate tasks and streamline your workflows. These scripts can be written in a variety of languages, such as Python, Bash, or PowerShell, and are used to perform a wide range of tasks, from simple file management to complex system configurations. While at their heart scripting and programing both involve giving instructions to a computer, the key difference between the two is the scope of the tasks they are used for. Programming languages are typically used to build large, complex applications that have a wide range of features. Scripting languages, are often used for more focused tasks, like automating a series of commands or integrating different applications. Scripting allows you to automate tasks that would otherwise be time-consuming or tedious to do manually.

PowerShell is like the multitool in a Windows admin's toolkit. Developed by Microsoft, it's designed to streamline and automate the nitty-gritty of system administration. From managing files and processes to configuring services and extracting data, PowerShell offers a robust set of cmdlets that make life easier for those navigating the Windows ecosystem. Alright, you've got a book with "PowerShell" boldly stamped on the cover. No pretenses here; we both know why you're here. Looking for some shortcuts or tech wizardry? Maybe a bit of both? Hold onto that curiosity. As we progress, we'll get hands-on with all the practical PowerShell know-how you're itching for.

The main advantages of using PowerShell include its versatility, extensibility, and ease of use. PowerShell supports a wide range of commands, and modules, which can be used to manage and automate a variety of tasks. PowerShell also provides programmer with consistent syntax and object-oriented design, which makes it easy to learn and use, even for those who are not experienced with programming languages. PowerShell is built on top of the .NET Framework (don't worry if you're not familiar with .NET) and utilizes its rich set of libraries and APIs. This provides access to a wide range of functionalities, including file system management, registry management, and network management. Additionally, PowerShell provides support for modules and plugins, which can extend its capabilities and provide additional functionality.
