Ever wanted to support the risk mitigation parameters –WhatIf and –Confirm in your functions, too?
Here’s a code template that you can use to play and see how this works. It’s just a few lines of code:
function Check-RiskMitigation { [CmdletBinding(SupportsShouldProcess=$True)] param() ' THIS ALWAYS WORKS' if ($PSCmdlet.ShouldProcess("localhost", "Trying to do something real bad")) { 'I AM DOING SERIOUS STUFF HERE' } else { 'I AM JUST KIDDING...' } ' THIS ALWAYS WORKS' }
Run this function, then check out how it responds to the parameters –WhatIf and –Confirm:
PS> Check-RiskMitigation THIS ALWAYS WORKS I AM DOING SERIOUS STUFF HERE THIS ALWAYS WORKS PS> Check-RiskMitigation -WhatIf THIS ALWAYS WORKS What if: Performing operation "Trying to do something real bad" on Target "localhost". I AM JUST KIDDING... THIS ALWAYS WORKS PS> Check-RiskMitigation -Confirm THIS ALWAYS WORKS Confirm Are you sure you want to perform this action? Performing operation "Trying to do something real bad" on Target "localhost". [Y] Yes [A] Yes to All [N] No [L] No to All [S] Suspend [?] Help (default is "Y"): y I AM DOING SERIOUS STUFF HERE THIS ALWAYS WORKS PS> Check-RiskMitigation -Confirm THIS ALWAYS WORKS Confirm Are you sure you want to perform this action? Performing operation "Trying to do something real bad" on Target "localhost". [Y] Yes [A] Yes to All [N] No [L] No to All [S] Suspend [?] Help (default is "Y"): n I AM JUST KIDDING...
