Batch file CertUtil-哈希文件输出到文件和错误处理

我需要从同一批处理文件中生成的文件列表中生成一个带有hashfile标记的文件。以下是我目前掌握的代码：

@echo off
setlocal enabledelayedexpansion

:: Set the variables for this script.
set testfolder=c:\test\test folder
set listfile=c:\test\output\file list.txt
set hashfile=c:\test\output\hashes.txt

:: Delete any of the files that were created the last time this script was ran.
del "%hashfile%"
del "%listfile%"
cls

:: Generate a file with a list of all of the files (with path) in designated folder and subdirectories.
:: Directory and subdirectory names are not included in the list. Only files.
dir /s /b /a-d "%testfolder%" > "%listfile%"

:: Assign each line of the file above to its own variable.
set counter=1
for /f "usebackq delims=" %%x in ("%listfile%") do (
  set "line_!counter!=%%x"
  set /a counter+=1
)

:: Count the number of lines in the above file to use as a reference point.
set /a numlines=counter - 1

:: Generate an MD5 hash for each variable and write it to a file with a blank space between each.
for /l %%x in (1,1,%numlines%) do (
  certutil -hashfile "!line_%%x!" MD5 >> "%hashfile%"
  echo( >> "%hashfile%"
)
eof

对于我为其生成哈希文件的大多数文件，我得到如下结果：

MD5 hash of file c:\test\test folder\Citrix 2.bmp:
31 34 d6 04 cd b0 4b ef a7 63 c3 e9 ae a8 3d 01
CertUtil: -hashfile command completed successfully.

但有时会出现如下错误：

CertUtil: -hashfile command FAILED: 0x800703ee (WIN32: 1006)
CertUtil: The volume for a file has been externally altered so that the opened file is no longer valid.

为什么有些文件会出现此错误

如何删除以CertUtil开头的任何行：这样我就没有多余的行，或者有没有办法只将CertUtil命令的前两行写入文件

在

%hashfile%

以其最终形式出现后，我想运行

certutil-hashfile”%hashfile%MD5

，并仅将哈希代码分配给一个变量。其语法是什么

稍微修改的代码片段显示

0x800703ee（WIN32:1006错误\u文件\u无效）

仅针对零长度文件的错误消息（参见

rem

注释）

有关

%%~zG

和

“%%~G”

说明，请参见。

IMO批次中的计数步骤更容易通过查找/v/N完成

但是，由于每次批处理运行时都会重新创建列表和哈希文件，因此根本不需要中间步骤。
此堆叠for-if-for将在一次运行中完成：

@echo off
setlocal enabledelayedexpansion

:: Set the variables for this script.
set testfolder=c:\test\test folder
set hashfile=c:\test\output\md5-hashes.csv

>%hashfile% (
  echo "File","MD5-hash"
  For /f "delims=" %%A in (
    'dir /s /b /a-d "%testfolder%"'
  ) Do If %%~sA Gtr 0 For /f "delims=" %%B in (
    'certutil -hashfile %%A MD5 ^|findstr /i ^[0-9a-f][0-9a-f].[0-9a-f][0-9a-f].[0-9a-f][0-9a-f]'
  ) Do Echo:"%%~A","%%~B"
)
