给定两个目录树，我怎么可以找出哪些文件有什么不同？ [英] Given two directory trees, how can I find out which files differ?

问题描述

如果我想找到两个目录树之间的差异，我通常只执行：

If I want find the differences between two directory trees, I usually just execute:

diff -r dir1/ dir2/

这正是输出的差异相应的文件之间什么。我感兴趣的是刚开相应的文件，其内容不同的列表。我认为，这将仅仅是传递一个命令行选项来差异的事，但我无法找到该名男子页上的任何东西。

This outputs exactly what the differences are between corresponding files. I'm interested in just getting a list of corresponding files whose content differs. I assumed that this would simply be a matter of passing a command line option to diff, but I couldn't find anything on the man page.

有什么建议？

推荐答案

您说的Linux，所以你的运气了（至少应该是可用的，不知道什么时候加入的话）：

You said Linux, so you luck out (at least it should be available, not sure when it was added):

diff --brief -r dir1/ dir2/

应该做你所需要的。

Should do what you need.

如果您也想看看，可能无法在任一目录下存在文件之间的差异：

If you also want to see differences for files that may not exist in either directory:

diff --brief -Nr dir1/ dir2/
