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)
