List the s3 buckets.
Then you can use the aws s3 cp command to copy the file from your S3 bucket to your EC2 instance and view content of file using cat command.
Task-04
Create a snapshot of the EC2 instance and use it to launch a new EC2 instance.
Download a file from the S3 bucket using the AWS CLI.
Verify that the contents of the file are the same on both EC2 instances.
Select Snapshots from the Elastic Block Store in the EC2 dashboard in the Left-Hand column.

here login as the user "ubuntu" rather than the user "root"(replace root by ubuntu in the ssh command)
Download a file from the S3 bucket using the AWS CLI.
aws s3 cp command to download the file from your S3 bucket to your EC2 instance.
Verify that the contents of the file are the same on both EC2 instances.
Here are some commonly used AWS CLI commands for Amazon S3:
aws s3 ls - This command lists all of the S3 buckets in your AWS account.
aws s3 mb s3://bucket-name - This command creates a new S3 bucket with the specified name.
aws s3 rb s3://bucket-name - This command deletes the specified S3 bucket.
aws s3 cp file.txt s3://bucket-name - This command uploads a file to an S3 bucket.
aws s3 cp s3://bucket-name/file.txt . - This command downloads a file from an S3 bucket to your local file system.
aws s3 sync local-folder s3://bucket-name - This command syncs the contents of a local folder with an S3 bucket.
aws s3 ls s3://bucket-name - This command lists the objects in an S3 bucket.
aws s3 rm s3://bucket-name/file.txt - This command deletes an object from an S3 bucket.
aws s3 presign s3://bucket-name/file.txt - This command generates a pre-signed URL for an S3 object, which can be used to grant temporary access to the object.
aws s3api list-buckets - This command retrieves a list of all S3 buckets in your AWS account, using the S3 API.
