title: Mayx应聘失败
tags: [应聘, Shell, 运维, 面向时间]
今天，Mayx去某公司面试运维，然后考官出了一道题：
如何用Linux shell排序？<!--more-->
Mayx想了想，写出了以下代码：
```shell
#!/bin/sh
num="4 5 1 9 3 6 7 4 1 12"
for j in $num
do
{
sleep $j
printf "$j "
}&
done
wait
```
执行效果：`1 1 3 4 4 5 6 7 9 12`
然后，Mayx被赶出来了……
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！
后来才知道，他们想让我回答`sort`，果然是垃圾公司（笑）
