假设你的文件格式是.txt。用到了临时文件，我觉得这样效率要好一点。

@echo off
setlocal enabledelayedexpansion
for /f "tokens=1* delims=:" %%a in ('findstr /n ".*" base.txt') do (
if %%a lss 964 (echo,%%b>>a.log) else if %%a gtr 964 (echo,%%b>>b.log)
)
for /l %%i in (1,1,1000) do (
(type a.log
echo,^<seed^>%%i^<seed^>
type,b.log)>%%i.txt
)
del a.log
del b.log
pause
