批处理：多个 for /f 命令

Question

我正在尝试为我的朋友做 "game" 但是当我尝试从保存文件加载时它会完成一半的工作

代码

set penize=0
set penizesekunda=0
for /f "EOL=: tokens=* Delims=0" %%a in (penize.txt) do (
set penize=%%a
)
for /f "EOL=: tokens=* Delims=1" %%b in (penize.txt) do (
set penizesekunda=%%b
)


echo Penize %penize% penize za sekundu %penizesekunda%

对不起，用我的语言（penize = money，penizesekunda = money per second）

输入的是 200 200 但应该是 500 200。

如果你想要完整的代码：

@echo off
title Hra (Imui)
color 6a
echo Ahoj %computername%     cas %time%     datum %date%
echo.
echo.
echo Vitej ve hre
echo.
echo.
echo.
echo Tvym cilem bude ovladnout cely VESMIR
echo.
timeout>nul /t 3 /nobreak
echo Nacitani!
set penize=0
set penizesekunda=0
for /f "EOL=: tokens=* Delims=0" %%a in (penize.txt) do (
set penize=%%a
)
for /f "EOL=: tokens=* Delims=1" %%b in (penize.txt) do (
set penizesekunda=%%b
)
if errorlevel 1 do (
echo Pozor nebyla nalezena zadna ulozena hra nebo doslo k chybe startovani!            (hry se nachazeji v souboru penize.txt)
timeout>nul /t 3 /nobreak
cls
goto Start
)

:Start
cls
set /p "Password=Zadej heslo > " 
if %Password%== Admin goto RMV
if NOT %Password%== Imui goto FAIL
if %Password%== Imui goto HesloSpravne
goto Start

echo Spatne heslo!
echo Zadej heslo prosim (zbyvaji 2 pokusy)
set /p "Password=Zadej heslo > "
if %Password%== Admin goto RMVCzech
if NOT %Password%== Imui goto FailTwo
if %Password%== Imui goto HesloSpravne
goto Fail

goto HlavniMenu


:HlavniMenu

echo %penizesekunda% %penize%

penize.txt 的内容：

500
200

Answer 1

这里有一些示例代码供您参考：

REM Get first line of a file
set /p penize=<penize.txt

REM Get second line of a file
for /f "skip=1" %%a in (penize.txt) do set penizesekunda=%%a

Answer 2

另一个（更有效的）选项是使用 SET /P 读取每一行：

<penize.txt (
  set "penize="
  set /p "penize="
  set "penizesekunda="
  set /p "penizesekunda="
)

存在用于清除每个变量的简单 SET 语句，以防文件中的行恰好为空或丢失，在这种情况下，SET /P 将保留任何预先存在的变量值。

可以使用 FOR 循环来缩短代码，尤其是当您有更多行要阅读时：

<penize.txt ( for %%V in (penize penizesekunda) do (
  set "%%V="
  set /p "%%V="
))

请注意，您可以在单独的行中列出变量，这有助于提高可读性：

<penize.txt ( 
  for %%V in (
    penize
    penizesekunda
  ) do (
    set "%%V="
    set /p "%%V="
  )
)
