title: Powershell: Pipe external command output to another external command
body: <p>How can I get PowerShell to understand this type of thing:</p>
  
  <pre><code>Robocopy.exe | Find.exe "Started"
  </code></pre>
  
  <p>The old command processor gave a result, but I'm confused about how to do this in PowerShell:</p>
  
  <pre><code>&amp;robocopy | find.exe "Started"                #error
  &amp;robocopy | find.exe @("Started")             #error
  &amp;robocopy @("|", "find.exe","Started")        #error
  &amp;robocopy | &amp;find @("Started")                #error
  &amp;(robocopy | find "Started")                  #error
  </code></pre>
  
  <p>Essentially I want to pipe the output of one external command into another external command. In reality I'll be calling flac.exe and piping it into lame.exe to convert FLAC to MP3.</p>
  
  <p>Cheers</p>
