image - 如何使用批处理文件将随机图像从文件夹复制到其他文件夹？

Question

我有2个文件夹：

D:\Folder 1\
D:\Folder 2\

:: Sorts the generated random numbers and choose a random file.
For /F "TOKENS=*" %%# in ('Type "%TEMP%\TempFile.txt" ^| SORT ^| MORE +%RANDOM:~1,1%') DO (

@echo off
setlocal

:: Initialization
set "ext=jpg"
set "source=folder 1"
set "target=folder 2"

:: Get count of images and select random image
for /f %%N in ('dir /b "%source%\*.%ext%"^|find /c /v ""') do (
  set /a "imageNum=%random% %% %%N"
)

:: Copy the image
if %imageNum% gtr 0 (set "skip=skip=%imageNum%") else set "skip="
for /f "%skip% eol=: delims=" %%F in ('dir /b "%source%\*.%ext%"') do (
  echo copy /y "%source%\%%F" "%target%\1.%ext%"
  exit /b
)
