PowerShell - Scripting Best Practices

You wrote this function:

function Delete-Data {
  param([string]$File)
  if ($PSCmdlet.ShouldProcess($File)) {
    Remove-Item $File
  }
}

But when you run Delete-Data -File 'data.txt' -Confirm, it does not ask for confirmation. Why?

AYou must add <code>-WhatIf</code> to enable confirmation.

BThe function lacks <code>[CmdletBinding(SupportsShouldProcess=$true)]</code> attribute.

CThe <code>param</code> block is missing <code>[switch]$Confirm</code> parameter.

DRemove-Item does not support confirmation.

Step-by-Step Solution

Solution:

Step 1: Check function attributes for Confirm support
The function is missing [CmdletBinding(SupportsShouldProcess=$true)], which enables -Confirm and -WhatIf support.
Step 2: Understand effect of missing attribute
Without this attribute, the function ignores -Confirm and does not prompt.
Final Answer:
The function lacks [CmdletBinding(SupportsShouldProcess=$true)] attribute. -> Option B
Quick Check:
Missing CmdletBinding disables Confirm = A [OK]

Quick Trick: Add CmdletBinding to enable -Confirm prompts [OK]
