【转载】【Windows批处理IV】批量进行文件重命名

1.过滤文件名中所有数字、汉字、特殊字符(含空格)

@echo off 
for %%a in (*.*) do ( 
if "%%~nxa" neq "%~nx0" ( 
set "name=%%~na" 
setlocal enabledelayedexpansion 
set name1=!name! 
call :lp 
ren "!name!%%~xa" "!nam!%%~xa" 
set "nam=" 
endlocal 
) 
) 
pause 
:lp 
if defined name1 ( 
set "var=!name1:~,1!" 
if "!var!" leq "Z" ( 
if "!var!" geq "a" ( 
set "nam=!nam!!var!" 
)) 
set "name1=!name1:~1!" 
goto lp 
) 

2.不过滤数字

@echo off 
setlocal enabledelayedexpansion 
set "n=1000" 
for /f "delims=" %%a in ('dir/b *.jpg') do call :a "%%a" 
for /f "delims=" %%a in ('dir/b/od *.jpg') do set/a "n+=1"&ren "%%a" "!n:~-3!%%~xa" 
exit 
:a 
ren "%~1" "%random%%~x1" || goto a

貌似含正则表达式语法，真心没看懂！以后研究吧。
