Question

test_title.bat

:GET_DOWNLOADS
set Counter=-1
for /f "DELIMS=" %%i in ('type version.txt') do (
set /a Counter+=2
set "Line_!Counter!=%%i"
)
if exist version.txt del version.txt
exit /b

:list_files
call :GET_DOWNLOADS
For /L %%C in (1,2,%Counter%) Do (
:: removing this part makes it work fine
set line=%%C
set /a line+=1
set /a line/=2
:: alternate way doesnt work either
REM set /a line=%line% / 2
:: this part without the math part would be %%C instead of %Line%
echo %line%. !Line_%%C!
)
pause

（做了编辑）第二部分由于某种原因不起作用它只是崩溃了如果我删除了做数学的线，它工作正常，但显示1. 3. 5. 7。

version.txt

everything
0
minecraft
0
steam
0
obs
0

修复了test_list.bat：D

@echo off
setlocal enabledelayedexpansion
set "num=1"
set "counter=0"
for /f "DELIMS=" %%i in (version.txt) do (
set /a num+=1
if "!num!"=="2" (set /a counter+=1&set "line_!counter!=%%i"&set num=0)
)

echo.

For /L %%C in (1,1,%Counter%) Do (echo %%C. !Line_%%C!)

for /f "DELIMS=" %%i in (version.txt) do (
    set /a num+=1
