a545910540

大佬们求助，这是要修改的内容，想把2021前的1和2统一改成一样的，然后在删除文本里重复的内容
例如：
N2310000000000114262120211015160049-2
N2310000000000114262220211015160049-2

path是系统默认环境变量，如果自定义变量跟它重名的话会导致很多问题，以后写其他脚本的时候请留意。

    没有系统的学过呀,在这里多回答问题不会的就搜以前的帖子灵活运用.

@echo off
setlocal enabledelayedexpansion
for /f "tokens=1* delims=-" %%i in (1.txt) do (
    set a=%%i
    set a=!a:~0,19!一样的!a:~21!
    set /a !a!+=1
    call;set #!a!-%%j=%%!a!%%
)
for /f "tokens=1,2 delims=#=" %%i in ('set #') do if %%j==1 echo %%i
pause

    谢谢，大佬，敢问你从哪学的bat脚本，我也想系统的学一下

修改之前：N2310000000000114262120211015160049-2-黑C5Y959.jpg
              N2310000000000114262220211015160049-2-黑C5Y959.jpg
修改之后：N231000000000011426一样的20211015160049-2-黑C5Y959.jpg
              N231000000000011426一样的20211015160049-2-黑C5Y959.jpg
改成这种形式的话要截取多少位呢，我现在怎么改 “-”后面的内容都带不出来
