PowerShell
Strumenti per PowerShell

Esempio 1: Questo comando copia l'oggetto "sample.txt" dal bucket «test-files» allo stesso bucket ma con una nuova chiave "sample-copy.txt».

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

Esempio 2: Questo comando copia l'oggetto "sample.txt" dal bucket «test-files» al bucket «backup-files» con una chiave "sample-copy.txt».

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

Esempio 3: Questo comando scarica l'oggetto "sample.txt" dal bucket «test-files» in un file locale con nome "local-sample.txt».

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

Esempio 4: scarica il singolo oggetto nel file specificato. Il file scaricato si trova in c:\downloads\data\archive.zip

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

Esempio 5: scarica tutti gli oggetti che corrispondono al prefisso chiave specificato nella cartella locale. La gerarchia delle chiavi relativa verrà conservata come sottocartelle nella posizione generale di download.

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