一、AWS S3

　　1、Managing Buckets 

　　　　High-level aws s3 commands support commonly used bucket operations, such as creating, removing, and listing buckets.

　　　　$aws s3 mb  s3://bucket_name 　　# create buckets 

　　　　$aws s3 rb　s3://bucket_name     　# remove buckets  [ the bucket must be empty  ]

　　　　$aws s3 rb   s3://bucket_name --force # remove buckets

　　　　$aws s3 ls 　　　　　　　　　　　　　# list buckets

　　　　　　CreationTime Bucket

　　　　　　$aws s3 ls s3://bucket_name

　　　　

　　2、Managing Objects

　　　　The high-level aws s3 commands make it convenient to manage Amazon S3 objects as well.

　　　　The object commands include aws s3 cp, aws s3 ls, aws s3 mv, aws s3 rm, and sync. The cp, ls, mv, and rm commands work similarly to their Unix counterparts and enable you to work seamlessly across your local directories and Amazon S3 buckets.

　　　　The sync command synchronizes the contents of a bucket and a directory, or two buckets.

　　　

　　　Note

　　　　All high-level commands that involve uploading objects into an Amazon S3 bucket (aws s3 cp, aws s3 mv, and aws s3 sync) automatically perform a multipart upload when the object is large.　　　　

　　　　Failed uploads cannot be resumed when using these commands. If the multipart upload fails due to a timeout or is manually cancelled by pressing CTRL+C, the AWS CLI cleans up any files created and aborts the upload. This process can take several minutes.

　　　　If the process is interrupted by a kill command or system failure, the in-progress multipart upload remains in Amazon S3 and must be cleaned up manually in the AWS Management Console or with the s3api abort-multipart-upload command.

　　

　　$aws cp /  mv / sync  + --grants Permission=Grantee_Type=Grantee_ID

　　　　Permission :  can be set : read , readacl , writeacl or full

　　　　Grantee_Type : Specifies how grantee is to be identified , 

　　　　　　can be set : uri , emailaddress , or id

　　　　Grantee_ID ： Specifies the grantee based on Grantee_Type

　　　　　　uri : The group's URI .

　　　　　　emailaddress : The account's email address

　　　　　　id : The account's canonical ID 

　　$aws s3 cp local_path/file_name s3://bucket_name/ --storage-class REDUCE_REDUNANCY

　　$aws s3 sync <source> <target> [--options]

　　　　　When the --recursive option is used on a directory/folder with cp, mv, or rm, the command walks the directory tree, including all subdirectories. These commands also accept the --exclude, --include, and --acl options as the sync command does.
