批处理重命名图片

1 批量重命名

新建文本文档，写入以下代码，并重命名为××.bat：

@echo off
set a=273
setlocal EnableDelayedExpansion
for %%n in (*.jpg) do (
set /A a+=1
ren "%%n" "A!a!.jpg"
)

2 代码雨

2.1 0和1代码雨

@echo off

setlocal ENABLEDELAYEDEXPANSION 
color 02 
for /l %%i in (1,1,80) do ( 
set Down%%i=0 
) 
:loop 
for /l %%j in (1,1,80) do ( 
set /a Down%%j-=1 
if !down%%j! LSS 0 ( 
set /a Arrow%%j=!random!%%4 
set /a Down%%j=!random!%%15+10 
) 
if "!Arrow%%j!" == "1" ( 
set /a chr=!random!%%2  
set /p=!chr!<NUL 
) else (  
set /p= <NUL  
)  
)  
goto loop  
goto :eof 

效果：从左到右随机输出0和1（字的颜色是绿色），因为快，所以后面分辨不出是从左到右，会产生是从上到下的视觉错觉。

2.2 个位数字随机代码雨

@echo off
title digitalrain
color 0b
setlocal ENABLEDELAYEDEXPANSION
for /l %%i in (0) do (
set "line="
for /l %%j in (1,1,80) do (
set /a Down%%j-=2
set "x=!Down%%j!"
if !x! LSS 0 (
set /a Arrow%%j=!random!%%3
set /a Down%%j=!random!%%15+10
)
set "x=!Arrow%%j!"
if "!x!" == "2" (
set "line=!line!!random:~-1! "
) else (set "line=!line! ")
)
set /p=!line!<nul
)

效果：蓝色的数字，之间空格随机。

2.3 数字代码雨

@echo off 
color 02 
:start 
echo %random% %random% %random% %rangom% %random% %random% %rangom% %random% %random% %random% %random% %rangom% %rangom% %rangom% %random% %random% %random% %random% %rangom% %rangom% 
goto start 

效果：绿色数字，非个位，随机
