Question

我想为我的朋友做一个程序，当我尝试为/ f命令做更多的事情时，它根本不起作用！

代码：

echo something1 > Settings.dll
echo something2 >> Settings.dll
echo something3 >> Settings.dll
for /f "skip=0" %%a in (Settings.dll) do set something1=%%a
for /f "skip=1" %%a in (Settings.dll) do set something2=%%a
for /f "skip=2" %%a in (Settings.dll) do set something3=%%a
echo %something1% %something2% %something3%
Pause>nul

但输出是：something1 something1 something1

Answer 1

如果您只想从文件中读取某些行，则更容易使用重定向。

保存

(
  echo John Smith
  echo 22
  echo 1
) > settings.txt

加载

(
  set /p name=
  set /p age=
  set /p times=
) < settings.txt

Answer 2

...并使用For循环：

For /F "Delims=" %%I In (Settings.dll) Do (If Not Defined Line1 (Set Line1=%%I
    ) Else (If Not Defined Line2 (Set Line2=%%I) Else (
            If Not Defined Line3 Set "Line3=%%I")))
Echo= %Line1% %Line2% %Line3%"
Pause>Nul

无法为/ f命令执行多个操作
