使用ls和通配符检查s3中是否存在文件 [英] Check if file exists in s3 using ls and wildcard

问题描述

似乎很简单，但是语法不正确.我想知道使用通配符的文件在我的s3存储桶中是否存在.像

Seems so simple, but not getting the syntax right. I want to know if a file exists in my s3 bucket using wildcards. Something like

aws s3 ls s3://my-bucket/folder/*myfile*

目标是查看此存储桶中是否存在名为2016_myfile.txt的文件或名为2011_myfile.csv的文件.

The goal is to see if a file called 2016_myfile.txt or a file called 2011_myfile.csv exists within this bucket.

如果我运行命令，即使我知道该文件存在，它也不会返回任何内容.

If I run the command, it doesn't return anything even though I know this file exists there.

推荐答案

(re-drafted from comment as it appears this answered the question)

根据文档，目前不支持. 最简单(尽管效率最低)的解决方案是使用grep:

I myself tried, and failed to use wildcards in the aws-cli, and according to the docs, this is not currently supported. Simplest (though least efficient) solution would be to use grep:

aws s3 ls s3://my-bucket/folder/ | grep myfile

或者，您可以编写一个简短的python/other脚本来更有效地执行此操作(但不能在单个命令中完成)

Alternatively, you could write a short python/other script to do this more efficiently (but not in a single command)
