<b>AI摘要</b>
<p id="ai-output">这篇文章讲述了Mayx在面试运维岗位时，因为未能准确理解考官的问题，把自己用sleep和printf实现数字排序的脚本当作sort来解答，导致实际执行效果与期望不符，因此面试未能通过。Mayx自己认为这是公司的问题，后来意识到公司期望的是使用真正的Linux sort命令，从而表达了对公司的不满。</p>

如何用Linux shell排序？<!--more--></p>
<p>Mayx想了想，写出了以下代码：</p>
<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="c">#!/bin/sh</span>
<span class="nv">num</span><span class="o">=</span><span class="s2">"4 5 1 9 3 6 7 4 1 12"</span>
<span class="k">for </span>j <span class="k">in</span> <span class="nv">$num</span>
<span class="k">do</span>
<span class="o">{</span>
<span class="nb">sleep</span> <span class="nv">$j</span>
<span class="nb">printf</span> <span class="s2">"</span><span class="nv">$j</span><span class="s2"> "</span>
<span class="o">}</span>&amp;
<span class="k">done
</span><span class="nb">wait</span>
</code></pre></div></div>
<p>执行效果：<code class="language-plaintext highlighter-rouge">1 1 3 4 4 5 6 7 9 12</code> </p><p>
然后，Mayx被赶出来了…… </p><p>
我写的代码明明可以执行，效果也没问题，居然赶我出来，这一定是个垃圾公司！ </p><p>
后来才知道，他们想让我回答<code class="language-plaintext highlighter-rouge">sort</code>，果然是垃圾公司（笑）</p></main>
