title: What does the & symbol in powershell mean?
body: <pre><code>$tool = 'C:\Program Files\gs\gs9.07\bin\gswin64c.exe'
  
  &amp; $tool -q -dNOPAUSE -sDEVICE=tiffg4 $param -r300 $pdf.FullName -c quit
  </code></pre>
  
  <p>Can someone explain to me how the this works? What exactly does the &amp; symbol do/mean in powershell?</p>
