[文本处理] [已解决]怎么写:检查重复文件名,并删除重复文件名的那一行？

@echo off
setlocal enabledelayedexpansion
for /f "delims=" %%j in (a.txt) do (
set "x=%%j"
(for /f "delims=" %%a in ('findstr /c:"%%~nxj" a.txt') do (
echo %%a )>> 8.txt
type 8.txt|find /c /v "">7.txt
del 8.txt
for /f "delims=" %%i in (7.txt) do (
if "%%i" gtr "1" (
echo !x! >>11.txt
) else ( echo !x! >> 10.txt )
)))
del 7.txt
pause
