Add-PSSnapin SqlServerCmdletSnapin100
Add-PSSnapin SqlServerProviderSnapin100

$Serverlist= Get-Content "D:\Lab\PowerShellTest\AllServerScript\ServerList.txt"
$SqlScript= "D:\Lab\PowerShellTest\AllServerScript\Script.sql"
$Outputfile= "D:\Lab\PowerShellTest\AllServerScript\Report_$((Get-Date).ToString('MM-dd-yyyy_hh-mm-ss')).csv"
$Logfile= "D:\Lab\PowerShellTest\AllServerScript\Log_$((Get-Date).ToString('MM-dd-yyyy_hh-mm-ss')).txt"
