How to use AWS S3 cp Recursive command

Are you looking for a way to copy multiple local files to S3? Our AWS experts have an easy solution to your query if the answer is yes. In fact, our experts are here to help us learn how to:

• Copy S3 objects to another local location or in S3 itself.
• Copy a local file to S3

This is done via the AWS S3 cp recursive command. In other words, the recursive flag helps carry out a command on all files or objects with the specific directory or folder. Hence, if we are carrying out a copy command with the recursive flag, the action is performed on all the objects in the folder.

For instance, if we want to copy the files from a local folder (local_folder) to an S3 bucket folder (s3_bucket_folder), we can use the following command:

 aws s3 cp local_folder s3://s3_bucket_folder/ --recursive

However, if we want to copy the files from the S3 bucket to the local folder, we would use the following AWS S3 cp recursive command:

aws s3 cp s3://s3_bucket_folder/ . --recursive

Additionally, we can use a dot at the destination end to indicate the current directory as seen in the example below:

aws s3 cp s3://s3_bucket_folder  . --recursive

aws s3 cp . s3://bucket-name  --recursive

Furthermore, the AWS S3 command-line interface supports exclude as well as include filters while specifying paths during file copying process. It supports the following symbols:

• ?: Matches any single character
• *: Matches everything
• [!sequence]: Matches any character not in sequence
• [sequence]: Matches any character in the sequence

When we are using multiple filters, the last one in the command takes precedence.

According to our AWS Support Team, we can get a quick preview of the changes that may be made by AWS S3 cp recursive command with the following command:

aws s3 cp --dryrun . s3://my-s3-bucket --recursive
