title: Powershell - Trying to test-path against a string that resembles a variable name
body: <p>The company I work for prefixes all their admin level accounts with a $ sign. Trouble, I know.</p>
  
  <p>I'm trying to use <code>test-path</code> to see if a folder exists like so:</p>
  
  <pre><code>$username = read-host "Enter Login ID:"
  </code></pre>
  
  <p>I type <code>$adminsdb</code> into the box and hit ok</p>
  
  <pre><code>##### Find TS Profile #####
  $TSProfile_exist = test-path "\\server\tsprofiles$\$username"
  </code></pre>
  
  <p>The folder DOES exist but... <code>$TSProfile_exist</code> is coming up False</p>
  
  <p>How do I handle the <code>$</code> in the username? I'm building this app to bring up quick stats on users in the environment.  We also have service accounts that are prefixed with # signs.</p>
