<div><p>通过批处理功能，arthas支持一次性批量运行多个命令，并取得命令执行的结果。</p>

<h2>使用方法<a class="headerlink" href="#id2" title="永久链接至标题">¶</a></h2>
<div class="section" id="id3">
<h3>第一步： 创建你的批处理脚本<a class="headerlink" href="#id3" title="永久链接至标题">¶</a></h3>
<p>这里我们新建了一个<code class="docutils literal notranslate"><span class="pre">test.as</span></code>脚本，为了规范，我们采用了.as后缀名，但事实上任意的本文文件都ok。</p>
<blockquote>
<div><p>注意事项</p>
<ul class="simple">
<li><p>目前需要每个命令占一行</p></li>
<li><p>dashboard务必开启批处理模式(<code class="docutils literal notranslate"><span class="pre">-b</span></code>)，指定执行次数(<code class="docutils literal notranslate"><span class="pre">-n</span></code>)，否则会导致批处理脚本无法终止</p></li>
<li><p>watch/tt/trace/monitor/stack等命令务必指定执行次数(<code class="docutils literal notranslate"><span class="pre">-n</span></code>)，否则会导致批处理脚本无法终止</p></li>
<li><p>可以使用异步后台任务，如 <code class="docutils literal notranslate"><span class="pre">watch</span> <span class="pre">c.t.X</span> <span class="pre">test</span> <span class="pre">returnObj</span> <span class="pre">></span> <span class="pre">&</span></code>，让命令一直在后台运行，通过日志获取结果，<a class="reference internal" href="async.html"><span class="doc">获取更多异步任务的信息</span></a></p></li>
</ul>
</div></blockquote>
<div class="highlight-default notranslate"><pre class="literal-block">➜ arthas git:(develop) cat /var/tmp/test.as
help
dashboard -b -n 1

</div>
</div>
<div class="section" id="id4">
<h3>第二步： 运行你的批处理脚本<a class="headerlink" href="#id4" title="永久链接至标题">¶</a></h3>
<p>通过<code class="docutils literal notranslate"><span class="pre">-b</span></code>开启批处理模式， <code class="docutils literal notranslate"><span class="pre">-f</span></code>执行脚本文件， 批处理脚本默认会输出到标准输出中，可以将结果重定向到文件中。</p>
<div class="highlight-bash notranslate"><div class="highlight hljs"><pre class="bash">./as.sh -b -f /var/tmp/test.as 56328 > test.out</pre></div>
