Cannot understand command line scripts of package.json
<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>
