Powershell tips: Find errors in scripts

It is never easy to find out syntax errors in scripts, but you can filter them like this:

filter Test-SyntaxError
{
  $text = Get-Content -Path $_.FullName
  if ($ -gt 0)
  {
   $err = $null
   $null = []::Tokenize($text, [ref] $err)
   if ($err) { $_ }
  }
}
