title: What does |% mean in PowerShell
body: <p>I've come across this today:</p>
  
  <pre><code>$tests = (Get-ChildItem . -Recurse -Name bin |% { Get-ChildItem $_ -Recurse -Filter *.Unit.Tests.dll } |% {  $($_.FullName) })
  Write-Host ------------- TESTS -----------
  Write-Host $tests
  Write-Host -------------------------------
  .\tools\xunit\xunit.console.exe $tests -xml test-report.unit.xml
  </code></pre>
  
  <p>I can't get my head around what '|%' is doing there. Can anyone explain what it used for please?</p>
