Scripting: Automation with Bash, PowerShell, and Python

For system administrators, developers, and anyone who regularly works with command lines, scripting is often the quiet superpower that turns repetitive tasks into automated workflows. Scripting: Automation with Bash, PowerShell, and Python takes a practical, cross-platform approach to this essential skill set, bringing together three of the most widely used scripting environments in one volume.

Three Languages, One Clear Workflow 💻

Rather than treating Bash, PowerShell, and Python as isolated tools, Michael Kofler uses real-world automation scenarios to show how each language handles similar problems. Readers gain insight into when one environment might be more efficient or natural than another, making it easier to pick the right tool for the job. The book covers command execution, variables, strings, control flow, I/O redirection, and error handling across all three languages, giving a solid foundation for building reliable scripts.

Practical Examples You Can Run Today

Early chapters introduce a set of ten compact examples that demonstrate each language in action. These include a Markdown spell checker in Bash, image sorting by date in PowerShell, and JSON-to-XML conversion in Python. Additional examples cover daily server backups, log file analysis, cloud file uploads, and virtual machine management. This hands-on approach lets readers immediately test the concepts and adapt the examples to their own environments.
