方法一：
@echo off&setlocal enabledelayedexpansion
for /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 /b
for /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 off
for /f "tokens=2 delims=:" %%a in ('find /c /v "" data.txt')do set/a result=%%a+0
echo,%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
