为什么`echo＆＃34; //＆＃34; | xargs -0`导致换行？

Question

test@hwy:~$ echo "//" | xargs -0
// 

test@hwy:~$ 

为什么这里有换行？为什么结果不如下？

test@hwy:~$ echo "//" | xargs -0
// 
test@hwy:~$ 

Man xargs无法告诉我原因。

   -0     Input  items  are  terminated  by a null character instead of by
          whitespace, and the quotes and backslash are not special  (every
          character is taken literally).  Disables the end of file string,
          which is treated like any other  argument. 

Answer 1

echo打印换行符，并告知xargs不考虑特殊字符。

您可以使用-n参数echo获得想要的效果。
