PowerShell - Scripting Best Practices

Given this function with Confirm support:

[CmdletBinding(SupportsShouldProcess=$true)]
function Remove-File {
  param([string]$Path)
  if ($PSCmdlet.ShouldProcess($Path)) {
    Remove-Item $Path
  }
}

What happens when you run Remove-File -Path 'test.txt' -WhatIf?

AIt shows a message about deleting 'test.txt' but does not delete it.

BIt deletes 'test.txt' without asking.

CIt asks for confirmation before deleting 'test.txt'.

DIt throws an error because -WhatIf is not supported.

Step-by-Step Solution

Solution:

Step 1: Understand the function's use of ShouldProcess
The function calls $PSCmdlet.ShouldProcess($Path), which respects -WhatIf and -Confirm.
Step 2: Effect of running with -WhatIf
Using -WhatIf causes ShouldProcess to return false but show what would happen, so Remove-Item is not called.
Final Answer:
It shows a message about deleting 'test.txt' but does not delete it. -> Option A
Quick Check:
-WhatIf shows action, no delete = B [OK]

Quick Trick: ShouldProcess respects -WhatIf to simulate actions [OK]

Common Mistakes:

Assuming -WhatIf deletes files
Confusing -WhatIf with -Confirm
Thinking function lacks support for -WhatIf
