title: Mayx应聘失败

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)
