title: Cannot understand command line scripts of package.json
body: <p>I am new to nodejs and its related technologies and trying to use it with webpack dev server and react js to run my website on windows machine. I have some commands in my package.json which I copied from some websites in internet such as :</p>
  
  <pre><code>webpack -d &amp;&amp; xcopy \"src/index.html\" \"dist/index.html\" /F /Y &amp;&amp; webpack-dev-server --content-base src/ --inline --hot --history-api-fallback --port 3003
  </code></pre>
  
  <p>or</p>
  
  <pre><code>"build:prod": "webpack -p &amp;&amp; xcopy \"src/index.html\" \"dist/\" /F /Y"
  </code></pre>
  
  <p>Which build my whole script object:</p>
  
  <pre><code>"scripts": {
  "test": "mocha --compilers js:babel-register --reporter dot --recursive",
  "start": "npm run build",
  "build": "webpack -d &amp;&amp; xcopy \"src/index.html\" \"dist/index.html\" /F /Y &amp;&amp; webpack-dev-server --content-base src/ --inline --hot --history-api-fallback --port 3003",
  "build:prod": "webpack -p &amp;&amp; xcopy \"src/index.html\" \"dist/\" /F /Y"
  </code></pre>
  
  <p>}</p>
  
  <p>It is working fine and I can interpret some part of the lines and some of commands such as F Y or -d are unclear for me.
  Although everything is working I do not have a good feeling about it since I do not have a clear understanding of what is going on. I searched the web for some documentation but I could not find anything useful or maybe I do not search in the right way. Is there any good documentation that can shed light on this?</p>
