Linux List files dfference - "ls" vs "ls /" : <p>Never used Linux before and trying to understand the difference between </p>

<pre><code>ls
</code></pre>

<p>and </p>

<pre><code>ls / 
</code></pre>

<p>"ls /" gets all my dir (and more, but not .files - hidden files) as we can see it in <a href="http://linuxcommand.org/lc3_man_pages/ls1.html" rel="nofollow noreferrer">this extensive list of commands</a>. </p>

<p>What about the <code>ls</code>?</p>
