【已解决】BAT：多个代码如何合并成一个

思想之翼

@echo off
for /f "skip=1 delims=" %%i in ('dir /b /a-d /o-n /s "d:\分解\数据1\0001\lishi\*.txt"') do (
    copy "%%i" "d:\分解\数据2\0001.txt"
    goto :eof
)

@echo off
for /f "skip=1 delims=" %%i in ('dir /b /a-d /o-n /s "d:\分解\数据1\0002\lishi\*.txt"') do (
    copy "%%i" "d:\分解\数据2\0002.txt"
    goto :eof
)

......

@echo off
for /f "skip=1 delims=" %%i in ('dir /b /a-d /o-n /s "d:\分解\数据1\1330\lishi\*.txt"') do (
    copy "%%i" "d:\分解\数据2\1330.txt"
    goto :eof
)

上述代码是将一文件夹内倒数第二行的txt文本数据导出
现在欲将上述若干代码合而为一，自己试写了如下代码，但是只能导出0001.txt，错在哪？

1. @echo off&setlocal enabledelayedexpansion
   
2. for /l %%x in (10001,1,11330) do (
   
3.     set y=%%x
   
4. pushd "d:\分解\数据1\!y:~1!\lishi"
   
5. for /f "skip=1 delims=" %%i in ('dir /b /a-d /o-n /s *.txt') do (
   
6.     copy "%%i" "d:\分解\数据2\!y:~1!.txt"
   
7.     goto :eof
   
8. )
   
9. )

WHY

1. @echo off&setlocal enabledelayedexpansion
   
2. for /l %%x in (10001,1,11330) do (
   
3.     set y=%%x&set "flag="
   
4.     pushd "d:\分解\数据1\!y:~1!\lishi"
   
5.     for /f "skip=1 delims=" %%i in ('dir /b /a-d /o-n *.txt') do (
   
6.         if not defined flag (
   
7.             copy "%%i" "d:\分解\数据2\!y:~1!.txt"
   
8.             set flag=1
   
9.         )
   
10.     )
    
11.     popd
    
12. )
