问题描述
我有两个包含所有相同文件和子文件夹的文件夹，但是每个文件中的内容可能已更改.我想编写一个批处理文件，它将搜索每个文件并查找任何差异.我想做的最好的工具是什么?
I have two folders that contain all the same files and subfolders, but the conents inside each file may have changed. I want to write a batch file that will search through each file and look for any differences. What's the best tool for what I want to do?
推荐答案
无需批处理文件.单个FC命令可以执行您想要的操作:
No need for a batch file. A single FC command can do what you want:
fc folder1\* folder2\*
如果需要，可以更具体地指定第一个文件夹中的文件掩码.例如folder1\*.txt.
You can be more specific for the file mask in the first folder if you want. For example folder1\*.txt.
该命令将报告在folder1中存在但在folder2中丢失的文件.文件夹2中的多余文件将被忽略.
The command will report on files that exist in folder1 but are missing in folder2. Extra files in folder2 are simply ignored.
FC命令有许多选项.在命令提示符下输入HELP FC或FC /?以获取更多信息.
There are a number of options to the FC command. Enter HELP FC or FC /? from the command prompt to get more information.

扩展解决方案以支持子文件夹有点棘手.使用FOR/R迭代给定根目录的文件夹层次结构很容易.问题在于获取相对路径，以便可以将层次结构应用于另一个根.
Extending the solution to support subfolders is a bit tricky. It is easy to iterate the folder hierarchy for a given root using FOR /R. The problem is getting the relative paths so that the hierarchy can be applied to another root.
最简单的解决方案是改用FORFILES，因为它直接支持相对路径.但是FORFILES是... S L O W:/
The simplest solution is to use FORFILES instead, since it directly supports relative paths. but FORFILES is... S L O W :/
此时，批处理文件很有意义:
At this point, a batch file makes sense:
@echo off
setlocal
set "folder1=c:\path\To\Folder1\Root"
set "folder2=d:\path\To\Folder2\Root"
set "fileMask=*"
for /f "delims=" %%F in (
'echo "."^&forfiles /s /p "%folder1%" /m "%fileMask%" /c "cmd /c if @isdir==TRUE echo @relpath"'
) do fc "%folder1%\%%~F\%fileMask%" "%folder2%\%%~F\*"
