<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph"><p>Shows a diff beween your current branch and it&#8217;s upstream. This is <em>roughly</em> the
same as:</p></div>
<div class="listingblock">
<div class="content">
<pre><code>git diff --patience -C -C HEAD@{upstream}  <b>&lt;1&gt;</b> <b>&lt;2&gt;</b></code></pre>
</div></div>
<div class="colist arabic"><ol>
<li>
<p>
<code>-C -C</code> detects file copies/renames
</p>
</li>
<li>
<p>
<code>--patience</code> uses the patience-diff algorithm, which tends to produce nicer
  diffs in many cases.
</p>
</li>
</ol></div>
<div class="paragraph"><p>The difference is that <code>HEAD@{upstream}</code> is actually the tagged merge base of
your branch (See <a href="git-rebase-update.html">git-rebase-update(1)</a>). This means that if your upstream
branch was rebased, but you haven&#8217;t yet rebased the current branch on top of it,
you&#8217;ll still see an accurate diff compared to just diffing against
<code>@{upstream}</code>.</p></div>
<div class="paragraph"><p>The <code>--wordwise</code> option also allows <code>git-diff</code> to do word-by-word comparison
in a semi-intelligent way. However, sometimes it can produce surprising results,
so it is disabled by default.</p></div>

<dt class="hdlist1">
<code>--staged</code>

<dd>
<p>
  Diff against the staged (cached) changes, instead of against the working
  directory. This is <em>substantially</em> faster on large repos, but doesn&#8217;t take
  into account unstaged changes (i.e. changes in your working copy which you
  haven&#8217;t staged with <code>git add</code>).
</p>
</dd>
<dt class="hdlist1">
<code>-- &lt;filename patterns&gt;*</code>
