[文件操作] [已解决]批处理如何随机重命名文件

rapmq0

求一段代码
把当前目录的所有文件重命名，后缀名不变
文件名有数字和小写字母组成，一共4位数，完全随机，并且不重复

idwma

@echo off
setlocal enabledelayedexpansion
set "s=0 1 2 3 4 5 6 7 8 9"
set "ss=a b c d e f g h i j k l m n o p q r s t u v w x y z"

for %%b in (*.*) do (
	if not "%%b"=="%~nx0" (
		call :loop
		ren "%%b" "!name!%%~xb"
		set loop=
		set name=
	)
)
pause
goto :eof

:loop
set /a loop+=1
if not "%loop%"=="5" (
	for %%a in (%s% %ss%) do (
		set /a n+=1
		set /a r=%random%
		set /a r=r%%36+1
		if "!r!"=="!n!" (
			set name=!name!%%a
			set n=
			goto :loop
		)
	)
)
goto :eof

换个方式再来一次

@echo off
setlocal enabledelayedexpansion
set "s=0123456789abcdefghijklmnopqrstuvwxyz"
for %%b in (*.*) do (
	if not "%%b"=="%~nx0" (
		call :loop
		ren "%%b" "!name!%%~xb"
		set loop=
		set name=
	)
)
pause
goto :eof
:loop
set /a loop+=1
set /a r=%random%%%36
set name=%name%!s:~%r%,1!
if "%loop%"=="4" goto :eof
goto :loop

还能再来一次是没想到的呀

@echo off
setlocal enabledelayedexpansion
set "s=0123456789abcdefghijklmnopqrstuvwxyz"
for %%b in (*.*) do (
	if not "%%b"=="%~nx0" (
		set /a ra=!random!%%36
		set /a rb=!random!%%36
		set /a rc=!random!%%36
		set /a rd=!random!%%36
		call;set name=%%s:~!ra!,1%%%%s:~!rb!,1%%%%s:~!rc!,1%%%%s:~!rd!,1%%
		ren "%%b" "!name!%%~xb"
	)
)
pause
