通过 AWS Powershell 工具向存储桶中的所有对象授予权限？

Question

I can grant specific permissions to a specific file easily, like this:

Set-S3ACL -BucketName "bucket" -Key "file.txt"

However, now I'm trying to do it for all the files:

Set-S3ACL -BucketName "bucket" -Key "*"

This does not work and it throws:

Set-S3ACL : The specified key does not exist.

What is the valid syntax in this case?

If you need to recursively apply the function to every file, you can achieve that with Get-ChildItem to get all of the files in a folder, and using Recurse to also search subfolders. Then loop those results and call the function for each one.

Get-ChildItem -Path $topfolder -Recurse | ForEach-object { Set-S3ACL -BucketName "bucket" -Key $_.Name }
