How to pass boolean values to a PowerShell script from a command prompt

Question

I have to invoke a PowerShell script from a batch file. One of the arguments to the script is a boolean value:

C:\\Windows\\System32\\WindowsPowerShell\\v1.0         


        

Answer 1

Try setting the type of your parameter to [bool]:

param
(
    [int]$Turn = 0
    [bool]$Unity = $false
)

switch ($Unity)
{
    $true { "That was true."; break }
    default { "Whatever it was, it wasn't true."; break }
}

This example defaults $Unity to $false if no input is provided.

Usage

.\RunScript.ps1 -Turn 1 -Unity $false
