从s3存储桶复制多个文件 [英] Copy multiple files from s3 bucket

问题描述

我无法将多个文件从AWS S3存储桶下载到本地计算机.

I am having trouble downloading multiple files from AWS S3 buckets to my local machine.

我拥有要下载的所有文件名，并且我不希望其他文件名.我怎样才能做到这一点 ?我可以做一些迭代的aws-cli中是否有任何循环?

I have all the filenames that I want to download and I do not want others. How can I do that ? Is there any kind of loop in aws-cli I can do some iteration ?

我需要下载数百个文件，因此似乎无法使用一个以所有文件名作为参数的命令.

There are couple hundreds files I need to download so that it seems not possible to use one single command that takes all filenames as arguments.

推荐答案

有一个bash脚本，可以从文件filename.txt中读取所有文件名.

There is a bash script which can read all the filenames from a file filename.txt.

#!/bin/bash  
set -e  
while read line  
do  
  aws s3 cp s3://bucket-name/$line dest-path/  
done <filename.txt
