Question

我有一个批处理文件。

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

call :extractDate firstLineDate firstLine 
<file set /p line=
echo "%line%"
for /f "tokens=2 delims=|" %%# in ("%line%") do set "_date=%%#"
echo %_date%

call :convertToJulianDay julianFirstLine firstLineDate
REM GET MONTH, DAY, YEAR VALUES
FOR /F "TOKENS=1-3 DELIMS=/" %%A IN ("%1") DO SET MM=%%A& SET DD=%%B& SET YY=%%C
REM ELIMINATE LEFT ZEROS
SET /A DD=10%DD% %% 100, MM=10%MM% %% 100
REM CALCULATE JULIAN DAY NUMBER
IF %MM% LSS 3 SET /A MM+=12, YY-=1
SET /A A=YY/100, B=A/4, C=2-A+B, E=36525*(YY+4716)/100, F=306*(MM+1)/10, JDN=C+DD+E+F-1524

set "today=%date%"
call :convertToJulianDay julianToday today
REM GET MONTH, DAY, YEAR VALUES
FOR /F "TOKENS=1-3 DELIMS=/" %%A IN ("%1") DO SET MM=%%A& SET DD=%%B& SET YY=%%C
REM ELIMINATE LEFT ZEROS
SET /A DD=10%DD% %% 100, MM=10%MM% %% 100
REM CALCULATE JULIAN DAY NUMBER
IF %MM% LSS 3 SET /A MM+=12, YY-=1
SET /A A=YY/100, B=A/4, C=2-A+B, E=36525*(YY+4716)/100, F=306*(MM+1)/10, JDN=C+DD+E+F-1524

set /a diff=julianToday-julianFirstLine
REM *** SECOND CHECK ***
if %diff% NEQ 1 goto :fail
exit /b

:fail
echo File doesn't fit

而bellow是示例input.txt

EOF

我想修改我的批处理文件以读取input.txt的第一行，如果date = sysdate-1而最后一行= EOF则继续执行prog。但是bat文件总是说：

The system cannot find the batch label specified - extractDate
The system cannot find the file specified.
The system cannot find the batch label specified - convertToJulianDay
The system cannot find the batch label specified - convertToJulianDay

Answer 1

阅读第一行很简单。

If not defined firstLine set firstLine=%%A

现在您需要提取日期然后将其转换为朱利安日期将系统日期转换为朱利安日期。
比较差异。

这就是全部

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

call :extractDate firstLineDate firstLine 
call :convertToJulianDay julianFirstLine firstLineDate
set "today=%date%"
call :convertToJulianDay julianToday today

set /a diff=julianToday-julianFirstLine
REM *** SECOND CHECK ***
if %diff% NEQ 1 goto :fail
exit /b

:fail
echo File doesn't fit

用于读取文本文件
