PowerShell
Tools for PowerShell

Example 1: This command copies the object "sample.txt" from bucket "test-files" to the same bucket but with a new key of "sample-copy.txt".

Copy-S3Object -BucketName test-files -Key sample.txt -DestinationKey sample-copy.txt

Example 2: This command copies the object "sample.txt" from bucket "test-files" to the bucket "backup-files" with a key of "sample-copy.txt".

Copy-S3Object -BucketName test-files -Key sample.txt -DestinationKey sample-copy.txt -DestinationBucket backup-files

Example 3: This command downloads the object "sample.txt" from bucket "test-files" to a local file with name "local-sample.txt".

Copy-S3Object -BucketName test-files -Key sample.txt -LocalFile local-sample.txt

Example 4: Downloads the single object to the specified file. The downloaded file will be found at c:\downloads\data\archive.zip

Copy-S3Object -BucketName test-files -Key data/archive.zip -LocalFolder c:\downloads

Example 5: Downloads all objects that match the specified key prefix to the local folder. The relative key hierarchy will be preserved as subfolders in the overall download location.

Copy-S3Object -BucketName test-files -KeyPrefix data -LocalFolder c:\downloads
