Which PowerShell feature provides examples and usage details for commands?

• A. Get-Help
• B. Get-Command
• C. Get-Member
• D. Select-String

Answer: (A)

Get-Help is the built-in help system in PowerShell that provides usage details and examples for commands. It not only describes what a cmdlet does, but also shows how to call it, including syntax, parameters, and practical usage examples. You can view the general help for a command, see only the examples with -Examples, or dive into full parameter details with -Full. If help content isn’t available locally, Update-Help can fetch the latest information from online sources.

The other options serve different purposes: Get-Command lists available commands and their basic invocation details, Get-Member reveals properties and methods of objects, and Select-String searches text. None are focused on providing command usage examples in the way Get-Help does.
