@echo off
type nul >b.txt
for /f "tokens=1* delims=:" %%a in ('type a.txt^|findstr /n .* ^&del a.txt') do if %%a leq 10 (echo,%%b>>b.txt) else (echo,%%b>>a.txt)
复制代码

@echo off
setlocal enabledelayedexpansion
cd.>b.txt
for /f "delims=" %%i in (a.txt) do (set /a a+=1
  if !a! leq 10 echo %%i>>b.txt)
ren a.txt a1.txt&more +10 a1.txt>a.txt&del a1.txt
pause
