Delete documents from SharePoint document library using PowerShell

So today we had to delete a bunch of documents from SharePoint, so I wrote this script to accomplish this task.

A couple of notes about the script:

1. By default it will not delete anything, just list the urls that contain the $document argument.
2. The $document argument is matched with like as it's matching urls, so be careful that it doesn't delete more documents than you want.

param
(
[string]$url = "https://sp.dev.local",
[string]$document = "Welcome"
[bool]$delete = false
)

$site = Get-SPSite $url

foreach($web in $site.AllWebs) {
    foreach($list in $web.Lists) {
              if($list.BaseType -eq "DocumentLibrary") {
                     foreach($item in $list.Items){
                           if($item.url -like "*$document*")
                           {
                                  if($delete)
                                  {
                                   Write-Host "Deleting $item.url"
                                   $item.File.Delete()
                                  }
                                  else
                                  {
                                   Write-Host "$item.url"
                                  }
                         }               
                      }
              }
       }
}
