方法一：
@echo off&setlocal enabledelayedexpansionfor /f "delims=" %%a in ('dir /a-d/b/s *.txt') do ( for /f "tokens=3 delims=:" %%b in ('find /c /v "" "%%a"') do set n=%%b ren "%%a" "%%~na_!n: =!%%~xa")pause
方法二：
@echo off & setlocal enabledelayedexpansion%1(for /f "delims=" %%i in ('%~0 :^|sort') do ren %%i)& pause & exit /bfor /f "tokens=1,* delims= " %%i in ('find /c /v "" *.txt') do ( set info=%%j set ln=!info:*:=! for /f "delims=" %%a in ("!ln!") do set fn=!info::%%a=! echo;"!fn!" "!fn:~,-4!!ln:~1!.txt")
批处理获取文件行数的方法
@echo offfor /f "tokens=2 delims=:" %%a in ('find /c /v "" data.txt')do set/a result=%%a+0echo,%result%pause
以上方法其实都大同小异，执行效率也差不多，小伙伴们需要的话自行选择吧
