How to Use -confirm in PowerShell

powershell

Solution

`-Confirm` is a switch in most PowerShell cmdlets that forces the cmdlet to ask for user confirmation. What you're actually looking for is the `Read-Host` cmdlet:

$confirmation = Read-Host "Are you Sure You Want To Proceed:"
if ($confirmation -eq 'y') {
    # proceed
}

or the `PromptForChoice()` method of the host user interface:

$title    = 'something'
$question = 'Are you sure you want to proceed?'

$choices = New-Object Collections.ObjectModel.Collection[Management.Automation.Host.ChoiceDescription]
$choices.Add((New-Object Management.Automation.Host.ChoiceDescription -ArgumentList '&Yes'))
$choices.Add((New-Object Management.Automation.Host.ChoiceDescription -ArgumentList '&No'))

$decision = $Host.UI.PromptForChoice($title, $question, $choices, 1)
if ($decision -eq 0) {
    Write-Host 'confirmed'
} else {
    Write-Host 'cancelled'
}

Edit:

As M-pixel pointed out in the comments the code could be simplified further, because the choices can be passed as a simple string array.

$title    = 'something'
$question = 'Are you sure you want to proceed?'
$choices  = '&Yes', '&No'

$decision = $Host.UI.PromptForChoice($title, $question, $choices, 1)
if ($decision -eq 0) {
    Write-Host 'confirmed'
} else {
    Write-Host 'cancelled'
}

Problem

I'm trying to take user input and before proceeding I would like get a message on screen and than a confirmation, whether user wants to proceed or not. I'm using the following code but its not working: ``` write-host "Are you Sure You Want To Proceed:" -Confirm ```
