find -exec 与 find | xargs 的差别 - SegmentFault



find -exec 与 find | xargs 的差别 - SegmentFault

最近我想统计下,家目录下各文件(夹)的硬盘占用情况,所以用了这个命令:
find -maxdepth 1 | xargs du -sh

返回的结果是,整个家目录的总大小,而不是预期的每个文件的大小。之后换用了find -maxdepth 1 -exec du -sh {} \;就能得出每个文件的大小。

为什么使用find | xargs得出的结果跟find -exec不一样呢?

一个问题是,我们为什么要使用xargs?xargs对find的标准输出做了什么处理?
