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)
