[文件操作] 请问BATCH如何根据一个文件复制1000个文件并将指定行的内容替换

@echo off
for /l %%a in (1,1,1000) do (
    (for /f "tokens=1* delims=:" %%i in ('findstr /n "." base') do (
        if %%i==964 (echo ^<seed^>%%a^<seed^>) else (echo;%%j)
    ))>%%a
)
pause
复制代码

@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
