Switch/Flag Parameters in PowerShell

I wanted to create a function with a ‘-force’ option.  First, I tried to add a [boolean] parameter, but that doesn’t work because it needs a value with the argument; I want it to be invoked with just the presence of the switch/flag.  Here’s how I finally did it:

function Update-Something {
    param(
        [switch] $force)

    if ($force) { 
        #do something here
    }
}


# use like:
$> Update-Something -force
