使用 PowerShell 递归删除 S3 存储桶下超过 30 天的文件而不删除文件夹

Question

I can delete files and exclude folders with following script

aws s3 rm s3://my-bucket/ --recursive --exclude="*" --include="*/*.*"

when i tried to add pipe to delete only older files, i'm unable to.. please help with the script.

aws s3 rm s3://my-bucket/ --recursive --exclude="*" --include="*/*.*" | Where-Object {($_.LastModified -lt (Get-Date).AddDays(-31))} 

Answer 1

The approach should be to list the files you need, then pipe the results to a delete call (a reverse of what you have). This might be better managed by a full blown script rather than a one line shell command. There's an article on this and some examples here .

Going forward, you should letS3 versioning take care of this, then you don't have to manage a script or remember to run it. Note: it'll only work with files that are added after versioning has been enabled.
