这里要补充一点:现在已经3年了，但当你输入“如何搜索S3 Bucket”时，这篇文章是谷歌的顶部。

也许你正在寻找一些更复杂的东西，但如果你在这里试图弄清楚如何简单地通过标题找到一个对象(文件)，这是疯狂的简单:

打开桶，选择右边的“none”，并开始输入文件名。

http://docs.aws.amazon.com/AmazonS3/latest/UG/ListingObjectsinaBucket.html

下面是一个使用AWS CLI搜索文件名的简短而丑陋的方法:

aws s3 ls s3://your-bucket --recursive | grep your-search | cut -c 32-

S3没有原生的“搜索此桶”，因为实际内容是未知的-此外，由于S3是基于键/值的，因此没有原生的方法可以一次访问多个节点，而更传统的数据存储提供了一个(SELECT * FROM…(在SQL模型中)。

您需要做的是执行ListBucket以获得bucket中对象的列表，然后遍历每个项，执行您实现的自定义操作—这就是您的搜索。

(至少)有两个不同的用例可以描述为“搜索桶”:

Search for something inside every object stored at the bucket; this assumes a common format for all the objects in that bucket (say, text files), etc etc. For something like this, you're forced to do what Cody Caughlan just answered. The AWS S3 docs has example code showing how to do this with the AWS SDK for Java: Listing Keys Using the AWS SDK for Java (there you'll also find PHP and C# examples). List item Search for something in the object keys contained in that bucket; S3 does have partial support for this, in the form of allowing prefix exact matches + collapsing matches after a delimiter. This is explained in more detail at the AWS S3 Developer Guide. This allows, for example, to implement "folders" through using as object keys something like folder/subfolder/file.txt If you follow this convention, most of the S3 GUIs (such as the AWS Console) will show you a folder view of your bucket.

使用Amazon Athena查询S3桶。另外，加载数据到Amazon Elastic搜索。希望这能有所帮助。

我尝试了以下方法

aws s3 ls s3://Bucket1/folder1/2019/ --recursive |grep filename.csv

这将输出文件存在的实际路径
