變化隨機子目錄批量

Question

我試着去改變任何的子目錄的文件夾中有一批

cd c:\* 

不工作，其實每次帶你到回收站

if exist * (
cd * 
) 

didnt工作

for %d in (*) do cd %d 

沒有工作

所以即時消失，有沒有辦法批量做到這一點？

Answer 1

@echo off 
setlocal EnableDelayedExpansion 
rem Create an array of dir. names 
set n=0 
for /D %%a in (c:\*) do (
    set /A n+=1 
    set dir[!n!]=%%a 
) 
rem Select a random element from the array 
set /A d=%random%*n/32768+1 
rem And CD to it 
cd "!dir[%d%]!" 

Answer 2

setlocal enabledelayedexpansion 
set c=0 
rem count dirs in c:\ 
for /d %%I in (c:\*) do set /a c+=1 >NUL 
set /a c=%RANDOM% * %c%/32768 + 1 >NUL 
set loop=0 
for /d %%I in (c:\*) do (
    set /a loop+=1 
    if !loop!==%c% cd /d "%%I" 
)
