【问题】
想要批量删除一些文件，知道linux中有管道和重定向，所以打算利用管道或重定向去批量删除。
结果是不行：

所以想要解决此问题。
【解决过程】
1.找了下，没有看到很好的解释。
但是看到有些好像提到了那个xargs。
2.参考：
先去看看这个xargs：
3.如此，就基本命令xargs的含义，并且知道此处不应该传递-0等参数了。
所以去试试：
Administrator@PC-20130611GART /cygdrive/e/Dev_Root/docbook/dev/books $ find . -name build.xml | xargs rm Administrator@PC-20130611GART /cygdrive/e/Dev_Root/docbook/dev/books $ find . -name build.xml
就可以实现，批量删除build.xml的效果了：
【总结】
此处，还是要明白用find和xargs组合，才能实现批量删除的效果。
所用命令如下：
find . -name build.xml | xargs rm
简单解释：
- find . -name build.xml ： 将当前文件夹下面的build.xml都找出来
- xargs rm ：通过xargs，将上面find出来的字符串，该字符串是一堆的文件其中是换行符隔开的，所以可以被xargs（去掉换行符）分割成一个文件的列表，送给rm去删除
