title: creating a .bat file with npm install command
body: <p>I created the following file</p>
  
  <p>//npminstall.bat</p>
  
  <pre><code>npm install
  echo hello
  </code></pre>
  
  <p>When I run the following command from Windows 10 Command Line (dos) <code>npminstall.bat</code>, the <code>npm install</code> command fires, but the <code>echo hello</code> doesn't fire.  I tried putting a semi-color after the first line like this <code>npm install;</code>, but all that did was give me the help instructions of npm .</p>
  
  <p>How do I get the second line <code>echo hello</code> to fire after the <code>npm install</code>?</p>
  
  <p><strong>Additional Notes</strong></p>
  
  <p>I have found that this also causes the same behaviour:</p>
  
  <p>//npminstall.bat</p>
  
  <pre><code>webpack
  echo hello
  </code></pre>
  
  <p>I think it's because both the <code>npm install</code> command and <code>webpack</code> command takes time to execute, and during that time it doe ssomething I don't expect to the second line.</p>
  
  <p><strong>Followup 2</strong></p>
  
  <p>//npminstall.bat</p>
  
  <pre><code>START /WAIT npm install
  echo hello
  </code></pre>
  
  <p>This seems to almost do what I want to do.  Except the npm install command causes a pop up window, and i have to shut down teh pop up window before it continues execution to echo hello world.  Can I get rid of the popup window?</p>
