title: What's the command of call operator &?
body: <p>I used <code>ls alias:</code> and tried to find <code>&amp;</code>. However, <code>&amp;</code> is not in the output. What's <code>&amp;</code>? Is it the combination of <a href="https://docs.microsoft.com/en-us/powershell/module/Microsoft.PowerShell.Core/Invoke-Command" rel="noreferrer"><code>Invoke-Command</code></a> and <a href="https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/invoke-expression?view=powershell-6" rel="noreferrer"><code>Invoke-Expression</code></a>? </p>
  
  <p>Are there any other operators which don't have a cmdlet in PowerShell?</p>
