Powershell script to run another powershell script and wait till over
<p>i'm trying to run a script which will run another powershell script. 
i need the first script to continue only after the other one is over.
something like:</p>

<p>start Copy.ps1 
wait till Copy.ps1 is done<br>
continue with the script</p>

<p>tried using the Invoke-Expression but it doesn't have wait parameter. </p>
