分小时复制文件到本地

从s3获取数据导本地，按照小时的形式，防止把时间当做文件复制到本地

#!/bin/bash
for j in {04..07}; do 
     hh=$j
      echo "hh is $hh"
       for i in `aws s3 ls  s3://ad/adn/path/impression/2016/05/12/virginia/$hh/|awk '{print $4}'  `  ; do
                #echo "aws s3 cp  s3://ad/adn/path/impression/2016/05/12/virginia/$hh/$i  ./ "; 
                        aws s3 cp  s3://ad/adn/path/impression/2016/05/12/virginia/$hh/$i  ./ ;  
                         done 
done
