Question

我有这个批处理代码，但是错了，我需要的是在屏幕上看到folder2中不在folder1中的文件的名称，将它们与你的HASH SHA1进行比较。临时文件位于同一目录中。感谢您的评论

@echo off
cd folder1
FOR /F "Delims=" %%A in ('DIR /B/A-D *.*') DO (
    certUtil -hashfile "%%A" SHA1 | findstr /VI "HASH"| findstr /VI "certutil"
) >>folder2\output.tmp

cd folder2
FOR /F "Delims=" %%B in ('DIR /B/A-D *.* ^|Findstr /VEIL ".tmp"') DO (
    certUtil -hashfile "%%B" SHA1 | findstr /VI "HASH"| findstr /VI "certutil" >>output2.tmp
    FOR /F "Delims=" %%C in ('TYPE output2.tmp^|findstr /XLIV /G:output.tmp') DO (echo "%%B") 
)

Answer 1

这是另一个不使用临时文件的解决方案。相反，它会创建一种像f|filename.ext=hash这样的关联数组。所有哈希都存储为变量，并且可以使用set "f|"枚举一系列变量。基本上，这可以很容易地获得与目录1中的文件名绑定的哈希列表，然后使用此列表来比较目录2.如果预期变量未定义，则目录2中的文件不存在于目录1中。如果它定义，然后比较哈希并取消定义它。无论在末尾定义什么，都表示目录1中存在文件，但目录2中不存在。

@echo off & setlocal

if "%~2"=="" goto usage

pushd "%~1" || goto usage
for /f "delims=" %%I in ('dir /b /a:-d') do (
    for /f %%x in ('certutil -hashfile "%%~I" ^| find /v ":"') do set "f|%%~nxI=%%~x"
)
popd

pushd "%~2" || goto usage
for /f "delims=" %%I in ('dir /b /a:-d') do (
    if not defined f^|%%~nxI (
        echo %%~nxI does not exist in %~nx1\
    ) else (
        for /f %%x in ('certutil -hashfile "%%~I" ^| find /v ":"') do (
            setlocal enabledelayedexpansion
            if not "%%~x"=="!f|%%~nxI!" (
                echo %%~nxI hash mismatch
            )
            endlocal
            set "f|%%~nxI="
        )
    )
)

for /f "tokens=2 delims=|=" %%I in ('cmd /c set "f|" 2^>NUL') do (
    echo %%I does not exist in %~nx2\
)

goto :EOF

:usage
echo Usage: %~nx0 dir1 dir2
echo compares files in dir1 with those in dir2.

Answer 2

certutil hash没有其他行的冒号。
只有哈希的文件没有相应的文件
以下批处理为两个文件夹
另外，如果文件夹1中存在，则检查来自folder2的每个哈希 - 如果不存在则回显到屏幕。

@echo off
Set Dir1=A:\
Set Dir2=Q:\Test\2017\08\03\

PushD "%Dir1%"
(FOR /F "Delims=" %%A in ('DIR /B/A-D *.*'
 ) DO For /f "delims=" %%B in (
 'certUtil -hashfile "%%A" SHA1 ^| findstr /V ":"'
 ) Do Echo %%B %%~fA
)> "%Dir2%\output1.tmp"
PopD

PushD "%Dir2%"
Type Nul >output2.tmp
FOR /F "Delims=" %%A in ('DIR /B/A-D *.* ^|Findstr /LIVE ".tmp"'
) DO For /f "delims=" %%B in ('certUtil -hashfile "%%A" SHA1 ^| findstr /V ":"') Do (
       >> output2.tmp Echo %%B %%~fA
       Findstr "%%B" output1.tmp >Nul 2>&1 || Echo Hash %%B not in "%Dir1%" File %%~fA 
     )
)
PopD
