PowerShell and SharePoint

I like to use PowerShell to read from SharePoint. It also allows me to debug quickly.
Here's an example of a script to list all lists from a web site.

$siteName = 'http://localhost:81'
# param([string] $siteName)


[void] [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SharePoint' ) | Out-Null

$site = New-Object -TypeName Microsoft.SharePoint.SPSite $siteName
[Microsoft.SharePoint.SPWeb] $web = $site.OpenWeb()
[Microsoft.SharePoint.SPListCollection] $lists = $web.Lists
Write-Host $sites.Count
[Microsoft.SharePoint.SPList] $list = $null

[int] $iList = 0
  for($iList = 0; $iList -lt $lists.Count; $iList++)
  {
     $list = $lists[$iList] 
  Write-Host $list.Title $list.TemplateFeatureId $list.BaseTemplate $list.ID
  
  }


Write-Host 'The end'
