window下自动下载AWS S3 file

使用了一个s3.exe, BAT文件如下:


echo off
echo Wscript.echo dateadd("d",-1,date)>vbs.vbs
set day=
for /f %%a in ('cscript //nologo vbs.vbs') do del vbs.vbs&&set yyyymmdd=%%a
for /f "tokens=1,2,3* delims=// " %%i in ('echo %yyyymmdd%') do set yyyy=%%i&set mm=%%j&set dd=%%k
if   %mm%   LSS   10   set   mm=0%mm%
if   %dd%   LSS   10   set   dd=0%dd%
set day=%yyyy%/%mm%/%dd%
echo %day%


set Dest=I:\work\X\Crash


md %Dest%\ipad\%yyyy%
md %Dest%\ipad\%yyyy%\%mm%
md %Dest%\ipad\%yyyy%\%mm%\%dd%
C:\s3 get log/%day%/ %crashDest%\%day% /sub /nogui
