PowerShell Prompt for Input Yes/No

PowerShell provides several ways to prompt users for input. The most common method is using the Read-Host cmdlet, but for Yes/No prompts, we often need more control.

Let me show you a few methods to prompt for input Yes/No in PowerShell.

Method 1: Using Read-Host for Simple Yes/No Prompts

The Read-Host cmdlet is easy to use for simple input prompts. Here’s how you can use it to ask a Yes/No question using the PowerShell script below.

$answer = Read-Host "Do you want to continue? (Yes/No)"
if ($answer -eq 'Yes') {
    Write-Output "Continuing the process..."
} elseif ($answer -eq 'No') {
    Write-Output "Process terminated."
} else {
    Write-Output "Invalid input. Please enter Yes or No."
}

In this example, the script prompts the user with “Do you want to continue? (Yes/No)” and captures the input. Based on the user’s response, it either continues the process or terminates it.

I executed the above PowerShell script, and you can see the exact output in the screenshot below:

Method 2: Using a Custom Function for Yes/No Prompts

You can create a custom function for more robust input handling. This method is useful when you need to reuse the prompt multiple times in your script.

function Read-YesNoChoice {
    param (
        [string]$Title = "Please Choose",
        [string]$Message = "Yes or No?"
    )
    $caption = "$Title"
    $choices = "&Yes", "&No"
    $defaultChoice = 1

    $choice = [System.Windows.Forms.MessageBox]::Show($Message, $caption, [System.Windows.Forms.MessageBoxButtons]::YesNo, [System.Windows.Forms.MessageBoxIcon]::Question, [System.Windows.Forms.MessageBoxDefaultButton]::Button1)

    return $choice
}

$choice = Read-YesNoChoice -Title "Confirmation" -Message "Do you want to proceed with the update?"
if ($choice -eq [System.Windows.Forms.DialogResult]::Yes) {
    Write-Output "Proceeding with the update..."
} else {
    Write-Output "Update canceled."
}

This function, Read-YesNoChoice, uses a message box to prompt the user. It’s more interactive and visually appealing, making it suitable for scripts that require user confirmation.

Method 3: Using Choice Command for Yes/No Prompts

The Choice command is another way to prompt for Yes/No input in PowerShell, especially useful in scenarios where you need to ensure valid input.

Add-Type -AssemblyName Microsoft.VisualBasic
$caption = "Confirmation"
$message = "Do you want to delete the user account?"
$buttons = [Microsoft.VisualBasic.MsgBoxStyle]::YesNo + [Microsoft.VisualBasic.MsgBoxStyle]::Question
$result = [Microsoft.VisualBasic.Interaction]::MsgBox($message, $buttons, $caption)

if ($result -eq [Microsoft.VisualBasic.MsgBoxResult]::Yes) {
    Write-Output "User account deleted."
} else {
    Write-Output "Operation canceled."
}

This method leverages the Microsoft.VisualBasic assembly to display a message box with Yes/No buttons, providing a clear and user-friendly way to capture input.
