问题描述
我在 S3 存储桶中有文件，我试图根据 8 月 8 日、8 月 9 日等日期下载文件，如何下载选择性日期文件?.我使用了以下代码，但它仍会下载整个存储桶列表
I have files in S3 bucket, I was trying to download files based on date like 08th aug, 09th Aug, how can I download selective date file?. I used following code but it still downloads entire bucket list
aws s3 cp s3://bucketname/ folder/file --profile pname --exclude "*" --recursive --include "" + "2015-08-09" + "*"
我不确定，如何实现这一点.
I am not sure, how to achieve this.
推荐答案
此命令将复制所有以2015-08-15开头的文件:
This command will copy all files starting with 2015-08-15:
aws s3 cp s3://BUCKET/ folder --exclude "*" --include "2015-08-15*" --recursive
如果您的目标是同步一组文件而不复制它们两次，请使用 sync 命令:
If your goal is to synchronize a set of files without copying them twice, use the sync command:
aws s3 sync s3://BUCKET/ folder
这将复制自上次同步以来添加或修改的所有文件.
That will copy all files that have been added or modified since the previous sync.
其实这相当于上面的cp命令:
In fact, this is the equivalent of the above cp command:
aws s3 sync s3://BUCKET/ folder --exclude "*" --include "2015-08-15*"
