How to Correctly Call a PowerShell Script with Parameters from Another Script

One of the common tasks in PowerShell scripting is to call one script from another. This is particularly useful when you want to modularize your code or reuse common functions across multiple scripts. However, understanding the correct way to pass parameters from one script to another is crucial for executing tasks efficiently.

Why Call Another Script?

Calling one PowerShell script from another allows for:

Modular Code: Breaking down tasks into separate scripts makes your project more organized and manageable.

Reusability: Functions and procedures defined in one script can be reused in multiple scripts.

Maintenance: Debugging and updating smaller scripts can be easier compared to handling a large script.

Best Practices

Validation: Always validate input parameters in the called script to avoid unexpected behaviors.

Consistency: Ensure parameter names are consistent and intuitive.

Documentation: Document the called script’s parameters and their expected values for easy maintenance and usage.

By adhering to these methods and best practices, you can efficiently modularize your PowerShell scripts and streamline their execution.

By leveraging these practices, you will reap the benefits of modular, maintainable, and reusable scripts in your PowerShell projects.
