PowerShell and Command Prompt (cmd.exe) are both command-line interfaces used in Windows environments, but they have distinct differences in terms of functionality, scripting capabilities, and overall power. Here’s a comparison:

PowerShell vs. Command Prompt

1. Language and Syntax:
   • Command Prompt (cmd.exe): Uses a simple batch scripting language. It’s less powerful and lacks the object-oriented approach. Commands are often text-based and less flexible.
   • PowerShell: Uses a more advanced scripting language based on .NET. It supports object-oriented programming, which allows for more complex and powerful scripting.
2. Commandlets vs. Commands:
   • Command Prompt: Relies on a limited set of built-in commands (like dir, copy, del) and external utilities.
   • PowerShell: Uses cmdlets (pronounced “command-lets”), which are specialized .NET classes designed for particular tasks. Cmdlets are more consistent and powerful, following a verb-noun naming convention (e.g., Get-ChildItem, Copy-Item).
3. Scripting Capabilities:
   • Command Prompt: Scripting is done through batch files (.bat or .cmd). These scripts are less powerful and can be cumbersome for complex tasks.
   • PowerShell: Scripting is done through PowerShell scripts (.ps1). These scripts are more powerful, supporting advanced programming constructs like loops, conditionals, functions, and error handling.
4. Output Handling:
   • Command Prompt: Output is typically plain text, which can be harder to manipulate and parse.
   • PowerShell: Output is object-based, making it easier to manipulate and process data. You can pipe objects between cmdlets to perform complex operations.
5. Integration and Extensibility:
   • Command Prompt: Limited integration with other Windows features and external tools.
   • PowerShell: Deep integration with Windows and other Microsoft products. It can leverage the full power of the .NET Framework and can be extended with modules and snap-ins.
6. Error Handling:
   • Command Prompt: Basic error handling capabilities.
   • PowerShell: Advanced error handling with try-catch blocks and detailed error messages.

Is PowerShell Better?

For most tasks, especially those involving automation, system administration, and complex scripting, PowerShell is generally considered superior to Command Prompt. Its advanced features, object-oriented approach, and deep integration with Windows make it a more powerful and flexible tool.

Script Writing in PowerShell

Writing scripts in PowerShell involves creating .ps1 files that contain PowerShell commands and logic. Here are some key points:

• Syntax: PowerShell scripts use a syntax similar to other programming languages, with support for variables, loops, conditionals, and functions.
• Cmdlets: Utilize cmdlets to perform tasks. Cmdlets are designed to be intuitive and consistent.
• Modules: PowerShell modules allow you to extend functionality by importing additional cmdlets and functions.
• Error Handling: Use try-catch blocks to handle errors gracefully.
• Pipelines: Leverage the pipeline to pass objects between cmdlets, enabling complex data manipulation.

Example PowerShell Script

# Example PowerShell script to list files in a directory and filter by extension
$directory = "C:\Example"
$extension = ".txt"

Get-ChildItem -Path $directory -Filter "*$extension" | ForEach-Object {
    Write-Host "File: $($_.Name), Size: $($_.Length) bytes"
}

In summary, PowerShell offers significant advantages over Command Prompt, particularly for scripting and automation tasks. Its advanced features and integration with the Windows ecosystem make it a powerful tool for system administrators and power users.
