推荐答案

这将解决问题，其中someFile.txt是您想要的文件阅读以下内容：

This will solve the problem, where someFile.txt is the file where you want to read the lines from:

for /f %%i in ('find /v /c "" ^< someFile.txt') do set /a lines=%%i
echo %lines%
set /a startLine=%lines% - 2
more /e +%startLine% someFile.txt > temp.txt
set vidx=0
for /F "tokens=*" %%A in (temp.txt) do (
    SET /A vidx=!vidx! + 1
    set localVar!vidx!=%%A
)
echo %localVar1%
echo %localVar2%
del temp.txt
