parametrar i powershell-funktioner

Man kan skapa funktioner med parametrar som påminner mycket om i C#. Så i stället för:

function Just-Test {
    Write-Host $args[0]
}

Skriv:

function Just-Test($param) {
    Write-Host $param
}

I det här exemplet är det inte så stor skillnad men tänk om du har flera parametrar. För det första behöver du inte hålla reda på vilket är vilket ($args[0], $args[1] osv) och för det andra är det också lättare att snabbare testa om de inte är null:

if($site -ne $null -and $url -ne $null)
    {"Url OR Site can be given"; return}
