删除基于MD5哈希的文件

Question

使用Windows命令行（而不是powershell），我想散列目录中的所有文件，然后删除与文本文件中包含的特定哈希集匹配的文件。

我考虑过使用md5deep，但我不确定匹配文件的输出是否可以重定向到删除命令。

感谢任何帮助，谢谢！

添加一些细节;这些文件位于名为“images”的目录中

md5deep.exe -r -b -x irrelevant_hashes.txt c:\images

这给了我一个我需要保留的文件列表。是否可以重定向MD5deep的输出以将“好”文件移动到另一个目录？

Answer 1

对于cmd行中的单个md5键，它非常简单： （这里使用64位变体）。

set "KillMD5=00112233445566778899aabbccddeeff"
for /f "tokens=1*" %A in ('md5deep64.exe *.* 2^>mul') do @if %A==%KillMD5% @Echo del "%B"

为了测试del命令只是回显。 在批处理文件中，%百分号加倍%%A/%%B

Answer 2

这使用纯浴文件，从windows使用CertUtil，因此没有第三软件需要。

您只需要提供2个变量的值：

set _nOp=irrelevant_hashes.txt ::文件文本，包含要删除的文件的md5数据

set "_path_gen=c:\images" ::将被删除的文件的路径。

另外，将带有md5的txt文件（在此代码中为irrelevant_hashes.txt）放在要删除的文件的同一文件夹中。

要从文件生成新的md5，并在命令行上使用certUtil：

   type nul >"%temp%\MD5_to_del.txt" & cd /d "c:\images" & for /f "tokens=* delims= " %i in ('^<nul dir /o-d /on /b "c:\images\*.*"') do for /f "tokens=* delims= " %M in ('certutil -hashfile "%i" md5 ^| find /v ":"') do echo/%M>>"%temp%\MD5_to_del.txt"

要从文件生成新的md5，并在file.bat上使用certUtil：

   type nul >"%temp%\MD5_to_del.txt" & cd /d "c:\images" & for /f "tokens=* delims= " %%i in ('^<nul dir /o-d /on /b "c:\images\*.*"') do for /f "tokens=* delims= " %%M in ('certutil -hashfile "%%i" md5 ^| find /v ":"') do echo/%%M>>"%temp%\MD5_to_del.txt"
