Simple powershell ISE script to replace/correct sitecore content items.

  Recntly, I got a requirement to update all the content item, basically replacing all spaces with _ (under score).

Here is simple script to do that.

 cd '/sitecore/content/Home/Test'  
 Get-ChildItem -Recurse . | Where-Object { $_.Name -match " " } | ForEach-Object {   
   $originalName = $_.Name  
   $newName = $originalName -Replace " ", "_"  
   Write-Host "Renaming item from " -nonewline;  
   Write-Host $originalName -f Yellow -nonewline;  
   Write-Host " to " -nonewline;  
   Write-Host $newName -f Green;  
   $_.Editing.BeginEdit()  
   $_.Name = $newName;  
   $_.Editing.EndEdit()  
 }  

We can extend this script to update/assoicate the image url for the catalog items and so It's taht much easy.
