windows 批处理文件脚本,用于从文件夹中选择随机文件并将它们移动到另一个文件夹

[英]windows batch file script to pick random files from a folder and move them to another folder

我需要一个批处理脚本来随机 select X 个文件夹中的文件并将它们移动到另一个文件夹。 如何编写 windows 批处理脚本来执行此操作?

(我假设您的X事先已知 - 由以下代码中的变量$x表示)。

由于您不会对PowerShell解决方案产生负面影响:

Get-ChildItem SomeFolder | Get-Random -Count $x | Move-Item -Destination SomeOtherFolder

或更短:

gci somefolder | random -c $x | mi -dest someotherfolder

以下批处理代码将执行此操作。 请注意,您需要使用以下命令行启动cmd:

cmd /v:on

启用延迟环境变量扩展。 另请注意,它将从0到32767选择随机数量的文件 - 您可能需要修改此部件以满足您的要求!

@ECHO OFF
SET SrcCount=0
SET SrcMax=%RANDOM%
FOR %F IN (C:\temp\source\*.*) DO IF !SrcCount! LSS %SrcMax% (
      SET /A SrcCount += 1
      ECHO !SrcCount! COPY %F C:\temp\output
      COPY %F C:\temp\output
      )

这是一个CMD代码,它输出随机文件名(根据您的需要定制):

@echo off & setlocal
set "workDir=C:\source\folder"
::Read the %random%, two times is'nt a mistake! Why? Ask Bill.
::In fact at the first time %random% is nearly the same.
@set /a "rdm=%random%"
set /a "rdm=%random%"
::Push to your path.
pushd "%workDir%"
::Count all files in your path. (dir with /b shows only the filenames)
set /a "counter=0"
for /f "delims=" %%i in ('dir /b ^|find "."') do call :sub1
::This function gives a value from 1 to upper bound of files
set /a "rdNum=(%rdm%*%counter%/32767)+1"
::Start a random file
set /a "counter=0"
for /f "delims=" %%i in ('dir /b ^|find "."') do set "fileName=%%i" &call :sub2
::Pop back from your path.
popd "%workDir%"
goto :eof
:: end of main
:: start of sub1
:sub1
::For each found file set counter + 1.
set /a "counter+=1"
goto :eof
:: end of sub1
:: start of sub2
:sub2
::1st: count again,
::2nd: if counted number equals random number then start the file.
set /a "counter+=1"
if %counter%==%rdNum% (
:: OUTPUT ALERT BOX with FILENAME
MSG * "%fileName%"
)
goto :eof
:: end of sub2
@echo off
setlocal EnableDelayedExpansion
cd \particular\folder
set n=0
for %%f in (*.*) do (
   set /A n+=1
   set "file[!n!]=%%f"
)
set /A "rand=(n*%random%)/32768+1"
copy "!file[%rand%]!" \different\folder

需要创建批处理文件,从文件夹中选择一个随机文件并复制到另一个文件夹

1000 个随机文件从C:\Test\A移动到C:\Test\B的示例Powershell 代码

$d = gci "C:\Test\A" | resolve-path  |  get-random -count 1000

回车键然后执行下面的代码

Move-Item $d  -destination "C:\Test\B"

不要忘记文件夹路径前后添加"标记
