CLI

AWS CLI

Para interromper um carregamento fracionado especificado

O comando abort-multipart-upload a seguir interrompe um carregamento fracionado da chave multipart/01 no bucket amzn-s3-demo-bucket.


aws s3api abort-multipart-upload \
    --bucket amzn-s3-demo-bucket \
    --key multipart/01 \
    --upload-id dfRtDYU0WWCCcH43C3WFbkRONycyCpTJJvxu2i5GYkZljF.Yxwh6XG7WfS2vC4to6HiV6Yjlx.cph0gtNBtJ8P3URCSbB7rjxI5iEwVDmgaXZOGgkk5nVTW16HOQ5l0R

O ID de upload exigido por esse comando é a saída de create-multipart-upload e também pode ser recuperado com list-multipart-uploads.
