<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>

<main class="post-content e-content" role="main"><p>今天Mayx去某公司面试运维然后考官出了一道题 </p><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>
