Is there a way to change the default confirmation option for a High Impact PowerShell script?
When I implement a Cmdlet and run it asking for Confirmation like
MyPS
Confirm
Are you sure you want to perform this action?
Performing operation "XYZ" on Target "123".
[Y] Yes [A] Yes to All [N] No [L] No to all [S] Suspend [?] Help (default is "Y"):
How can I change the default value? I want to change the default from "Y" to "N".

When you want to do a big script in PowerShell, sometimes it keeps asking you for confirmation even if you did not put the “-Confirm” parameter in your command. The answer is simple, just add -Confirm:$false .
You can use a script block to specify different default values for a parameter under different conditions. PowerShell evaluates the script block and uses the result as the default parameter value. The Format-Table:AutoSize key sets that switch parameter to a default value of True.
8.4. Using the confirm Parameter. The -confirm parameter allows you to step through the processing of a cmdlet and decide at each point whether to allow it to implement the intended action or to prevent it taking that action.
The default value of $ErrorActionPreference is Continue. When that is the setting, the appearance when running ForLoop. ps1 is the same as that shown in Figure 17-1.
It's a little unclear what you're trying to ask. Do you want to know how to set a global default (for a given PowerShell session) to suppress confirmation prompts for cmdlets that prompt for confirmation by default, so you don't have to keep specifying -Confirm:$false every time you run them? Set the default variable:
$ConfirmPreference = $false
Or are you asking how to change the confirm impact for a specific cmdlet? Declare [CmdletBinding(ConfirmImpact = 'high')] at the beginning of your script. Note that if you declare CmdletBinding, a param() block is required, even if it's empty.
