批处理中的嵌套

批处理中的嵌套

我不知道问题出在哪里。我有tool.exe一个用于 grep、读取和写入注册表的程序。

它有errorlevel代码0，1并且2，根据该工具的语法，一切都是正确的：

"%tool_ROOT%\BIN\tool.exe" /g "%%A" %%B "%%C"`

并且工作正常，除非我将代码包装到for do (cmd)
例子：

::   %%A   // is registry path 
::   %%B   // is parameter 
::   %%C   // is value*

@echo off

set logfile=log.LOG

for /F "tokens=1,2,3 delims=+" %%A in (CHECK.txt) do (
    "%tool_ROOT%\BIN\tool.exe" /g "%%A" %%B "%%C" 
    @if "%errorlevel%" == "0" (
        @ECHO %DATE% %TIME% ----- %%B WITH PARAMETER %%C ALREADY EXIST>>%logfile%
       )
    @if "%errorlevel%" == "1" ( 
        @ECHO %DATE% %TIME% -----CURRENT VALUE OF %%B is>>%logfile%
       )
    @if "%errorlevel%" == "2" (
        @ECHO %DATE% %TIME% -----%%B DOESN'T EXIST IN REGISTRY>>%logfile%
       )
    )

已经尝试过^每次关门前)

@echo off && setlocal

set "logfile=.\log.log"
set "tool_cmd=.\bin\tool.exe"

cd /d "Path\To\Tool\Exec\Root\Folder"

for /f "tokens=1-3 delims=+" %%a in ('type "File_Check.txt" ^| find "+" 
')do (call ) & "%tool_cmd%" /g "%%~a" %%~b "%%~c" & >>"%logfile%" (
     if "%errorlevel%" == "0" (echo\ %date% %time% ----- %%b with parameter %%c already exist 
        )else if "%errorlevel%" == "1" (echo\ %date% %time% ----- current value of %%~b is
        )else if "%errorlevel%" == "2" (echo\ %date% %time% ----- %%~b doesn't exist in registry
        ) ) 
    
timeout -1 | type "%logfile% & endlocal

1.定义变量时，请使用双引号，以防万一，或者像朋友说的那样，放心使用它们......

set "logfile=log.log"

2.设置可执行文件的完整路径，我没有在您的代码中看到它的定义，并且还设置了您的日志文件的完整路径......

set "logfile=D:\Path\To\log.log"
set "tool_cmd=D:\Path\To\Root\Tool\Folder\bin\tool.exe"

3.将您的文件提交给type命令，并使用find仅过滤带有分隔符的行+...

for ...('type "File_Check.txt" ^| find "+" ')do ...

4.由于一切都指向与errorlevel值相关的一些问题/行为，在使用执行命令之前...\tool.exe，重置errorlevel为0，进行测试并查看结果，当然之后你可以删除...

...)do (call ) & "%tool_cmd%" /g "%%~a" %%~b "%%~c"...

  • 观察：1请注意命令中有一个空格，这是必需的：(callspace)

  • 观察：2一个if接一个地if执行echo string，但如果实际上没有写入日志文件，则errorlevel此返回的值将是什么？errorlevel执行后值​​是否会改变echo string + redirector to file？这些很容易出现特殊情况，我强烈建议进行测试并阅读下面文本中链接的答案以更好地理解...

Also note - This answer does not attempt to document the ERRORLEVEL result when an internal command encounters an error (except for a wee bit concerning DEL and ERASE)

Not only are there difference between commands, but a single command can behave differently depending on whether it was run from the command line, or within a batch script with a .bat extension, or from within a batch script with a .cmd extension-@dbenham

5.在每个孤立的行上使用if condition() else if condition()...而不是if condition()，在下一行进行新的条件处理，即使它已经满足一个或多个前一行中定义的条件。

     if "%errorlevel%" == "0" (
          echo\ %date% %time% ----- %%b with parameter %%c already exist 
        ) else if "%errorlevel%" == "1" (
          echo\ %date% %time% ----- current value of %%~b is
        ) else if "%errorlevel%" == "2" (
          echo\ %date% %time% ----- %%~b doesn't exist in registry
        ) else (
          echo\ Look at this bro! 
          echo\ No previous one condition met as true! 
          echo\ What to do now?
          echo\ But if it is not necessary/does not occur, 
          echo\ you can remove the last else
          echo\ As i did in the answer code
        )

6.至于重定向到您的日志文件，我建议执行if块 [ >file-log (if ())] 内的命令，并且已经重定向一次，无论if condition或任何else if condition()返回同一文件的内容......

"%tool_cmd%" /g "%%~a" %%~b "%%~c" & >>"%logfile%" ( 
    if.. else if.. else if...
   )

观察：请注意，在没有看到文件内容（字符串布局）的情况下，我提出的建议仅仅来自假设......
