Question

我正在编写批处理文件以读取AML_handshake.txt日期并将日期与昨天的日期进行比较。如果它匹配并且最后一行= EOF则执行我的java程序。到目前为止，我已经吼到了。

@ECHO OFF 
SET CURRENTDATE=%DATE% 
SET LOGFILE_DATE=%DATE:~4,2%.%DATE:~7,2%.%DATE:~10,4% 
SET LOGFILE_TIME=%TIME:~0,2%.%TIME:~3,2% 
SET LOGFILE="C:\Extractor\log\AML_Data_Auto-%LOGFILE_DATE%-%LOGFILE_TIME%.log" 
call :Logit >> %LOGFILE% 
exit /b

:Logit 
set "firstLine" 
for /f "tokens=*" %%A in (C:\Extractor\AML_handshake.txt) do ( 
        If not defined firstLine set "firstLine=%%A" 
        set Lastline=%%A 
) 
REM *** FIRST CHECK *** 
if "EOF" NEQ "%Lastline%" goto fail 

REM *** SECOND CHECK *** 
IF "%CURRENTDATE%" NEQ "%firstLine%" goto fail 
exit /b 

goto prog 
:prog 
echo Incremental Data Extraction - Started 
sqlplus -s ***** @call_proc.sql 
echo Incremental Data Extraction - Ended 
echo Generating AML Files - Started 
start "C:\Extractor" TableExtractor.exe 
echo Generating AML Files - Ended 
echo Process Completed 

:fail 
echo Initial Check Failed, Process Terminated

要进行测试运行，我已将txt文件日期修改为当前日期并执行批处理文件，但在日志文件中，我总是看到＆＃34;初始检查失败，处理已终止＆＃34;。

Bellow是文本文件。

EOF

我想知道两件事。

1）如何比较文本文件日期和日期-1（昨天的日期）， 2）为什么即使我编辑文本文件日期，我的批处理文件也没有运行？

批处理文件中存在一些错误，包括一些难以检测的错误，例如将变量设置为末尾有一些额外空格的值，这导致您的条件进行比较，例如＆＃34; EOF＆＃34;用＆＃34; EOF＆＃34;。因此，请务必在 SET var = value 行的末尾删除多余的空格。

此外，您需要使用延迟扩展，因为您在 FOR循环中设置了变量值。这是批量的修订版本，应该执行您正在寻找的内容，并记录更多信息。

@ECHO OFF setlocal EnableDelayedExpansion SET CURRENTDATE=%DATE% SET LOGFILE_DATE=%DATE:~4,2%.%DATE:~7,2%.%DATE:~10,4% SET LOGFILE_TIME=%TIME:~0,2%.%TIME:~3,2% SET LOGFILE=AML_Data_Auto-%LOGFILE_DATE%-%LOGFILE_TIME%.log :Logit set firstLine= set lastLine= for /f "delims=" %%A in (handshake.txt) do ( if "!firstLine!"=="" set firstLine=%%A set lastLine=%%A ) set err= if "EOF" NEQ "!Lastline!" ( set err=LastLine should not be equal to "!Lastline!" goto fail ) else ( if "%CURRENTDATE%" NEQ "!firstLine!" ( set err=FirstLine is "!firstLine!" but today's date is "%CURRENTDATE%" goto fail ) ) echo Incremental Data Extraction - Started >> %LOGFILE% sqlplus -s ***** @call_proc.sql >> %LOGFILE% echo Incremental Data Extraction - Ended >> %LOGFILE% echo Generating AML Files - Started >> %LOGFILE% start "C:\Extractor" TableExtractor.exe >> %LOGFILE% echo Generating AML Files - Ended >> %LOGFILE% echo Process Completed >> %LOGFILE% goto :eof :fail echo Initial Check Failed, Process Terminated with error: %err% >> %LOGFILE% exit /b

就将文本文件日期与昨天的日期进行比较而言，问题是has already been answered。
