是以倒数第6行为标准吗？
累加以后还是倒数第6行？？

@echo %debug% off

setlocal enabledelayedexpansion

set line=0 && del rr.txt 2>nul



for /F %%i in (re.txt)                do ( set /a line+=1  &&  set "num!line!=%%i" )

start rr.txt

@echo off

我测试是取的倒数第5行，你把 set /a m=%%a-5
改为 6 就是倒数第6行了，其中的 %%a代表总行数，你想取第几行都可以，自己作个减法就行了。
