在窗口命令提示符下进行比较

Question

描述：
我想使用 COMP I：\folder1 Z：\folder2 这样的语法将我的 I 驱动器中的所有文件与我的 z 驱动器的内容进行比较。我只需要比较他们的名字，看看一个是否存在另一个。我需要递归到子目录中，因为两个驱动器中都有很多，我知道我需要使用 FOR 循环以及 PUSHD 和 POPD 命令使用批处理脚本。

问题：
我该怎么做？

Answer 1

来自 FOR/的输出？

FOR /R [[drive:]path] %variable IN (set) DO command [command-parameters]
    Walks the directory tree rooted at [drive:]path, executing the FOR
    statement in each directory of the tree.  If no directory
    specification is specified after /R then the current directory is
    assumed.  If set is just a single period (.) character then it
    will just enumerate the directory tree.

所以你会做这样的事情

@echo off
setlocal enabledelayedexpansion ENABLEEXTENSIONS
for /R P: %%F in (*.*) DO (
set fileFull=%%~fF
set filePath=%%~pF
set fileDrive=%%~dF
set fileName=%%~nF
set fileExtension=%%~xF
call :checker "!filePath!" "!fileName!" "!fileExtension!"
) 
goto :eof
:checker
set fileTarget="c:%~1%~2%~3"
if not exist %fileTarget% echo %fileTarget% not found
goto :eof

在这种情况下，脚本将获取 P：\ 中的所有文件名及其子目录，并告诉我该文件是否不存在于 C：

Answer 3

如果您确实需要避免第三方实用程序：

@ECHO OFF
SET FOLDER1=I:Folder1
SET FOLDER2=Z:Folder2
ECHO SET FNAME=%%1 ^& @ECHO %%FNAME:%FOLDER1%=%%^>^>FILES1.TXT>FILES1.BAT
ECHO SET FNAME=%%1 ^& @ECHO %%FNAME:%FOLDER2%=%%^>^>FILES2.TXT>FILES2.BAT
IF EXIST FILES1.TXT DEL FILES1.TXT
IF EXIST FILES2.TXT DEL FILES2.TXT   
FOR /F "tokens=*" %%* IN ('DIR /S /B /ON "%FOLDER1%"') DO CALL FILES1.BAT "%%*"
FOR /F "tokens=*" %%* IN ('DIR /S /B /ON "%FOLDER2%"') DO CALL FILES2.BAT "%%*"
ECHO Files from "%FOLDER1%" which are not found in "%FOLDER2%"
FOR /F "tokens=*" %%* IN (FILES1.TXT) DO (FIND %%* FILES2.TXT >NUL || ECHO %%*)
ECHO Files from "%FOLDER2%" which are not found in "%FOLDER1%"
FOR /F "tokens=*" %%* IN (FILES2.TXT) DO (FIND %%* FILES1.TXT >NUL || ECHO %%*)
