AWS CLI

L'esempio seguente utilizza il put-object comando per caricare un oggetto su Amazon S3:

aws s3api put-object --bucket text-content --key dir-1/my_images.tar.bz2 --body my_images.tar.bz2

L'esempio seguente mostra il caricamento di un file video (il file video viene specificato utilizzando la sintassi del file system Windows. ):

aws s3api put-object --bucket text-content --key dir-1/big-video-file.mp4 --body e:\media\videos\f-sharp-3-data-services.mp4
