Upload The Objects In S3

Step 1: In this example we are uploading the all the files present in directory to s3 bucket(gfg-example)

aws s3 cp <directory-name> s3://gfg-example --recursive

Download the Objects from S3

Step 1: In this example we just download the one file from above s3 bucket.

aws s3 cp s3://gfg-example/1.here-there-and-everywhere.pdf C:\Users\ravis\Desktop

Step 2: The above command downloads the 1.here-there-and-everywhere.pdf from gfg-example bucket to local Desktop.

The aws s3 rb command is used to delete s3 bucket and aws s3 rm is used to delete the objects from s3 bucket.

aws s3 rb <S3 URN>

The aws s3 rb deletes the s3 bucket if and only if bucket is empty

aws s3 em <S3 URN>

We can delete all the objects from s3 using –recursive option parameter.

Deleting S3 bucket using S3 cmd

Step 1: Deleting the one object from s3 bucket(gfg-example)

aws s3 rm s3://gfg-example/1.here-there-and-everywhere.pdf

Step 2: The above command will delete object named with 1.here-there-and-everywhere.pdf

Step 3: In this example first we try to delete the s3 bucket which is empty(gfg-example) then we will empty the bucket and then delete the s3 bucket(gfg-example)

aws s3 rb s3://gfg-example

Step 4: If the bucket is empty then above cmb directly delete bucket without any error. other wise it will give BucketNotEmptyError

aws s3 rm s3://gfg-example --recursive  #first delete all the objects present in given bucket
aws s3 rb s3://gfg-example   #delete the bucket
