About This Book
Master Cross-Platform Scripting with Bash and PowerShell
Bash vs PowerShell: Cross-Platform Scripting is a practical guide for professionals working in mixed Linux, Windows, macOS, and cloud environments. Modern IT infrastructure is increasingly heterogeneous, and the ability to script across platforms is a valuable skill.
This book focuses primarily on Bash while providing clear comparisons to PowerShell, helping you understand the strengths, limitations, and ideal use cases of each approach. You will learn when to use Bash, when to use PowerShell, and how to write scripts that work across different operating systems.
What You Will Learn
- Write portable Bash scripts that work across Linux, macOS, and Windows (WSL/Git Bash)
- Understand the philosophical differences between text-based (Bash) and object-based (PowerShell) shells
- Handle files, directories, and text processing in both environments
- Process management, system information, and automation tasks
- Networking, API calls, and JSON handling in Bash
- Compare real-world tasks implemented side-by-side in Bash and PowerShell
- Choose the right scripting tool for DevOps and automation workflows
- Cross-platform considerations and compatibility strategies
- Integrating Bash and PowerShell in hybrid environments
- Best practices for maintainable cross-platform scripts
Who Is This Book For?
