Downloading folders from aws s3, cp or sync?

Using aws s3 cp from the AWS Command-Line Interface (CLI) will require the --recursive parameter to copy multiple files.

aws s3 cp s3://myBucket/dir localdir --recursive

The aws s3 sync command will, by default, copy a whole directory. It will only copy new/modified files.

aws s3 sync s3://mybucket/dir localdir

Just experiment to get the result you want.

Documentation:

In the case you want to download a single file, you can try the following command:

aws s3 cp s3://bucket/filename /path/to/dest/folder

Just used version 2 of the AWS CLI. For the s3 option, there is also a --dryrun option now to show you what will happen:

aws s3 --dryrun cp s3://bucket/filename /path/to/dest/folder --recursive
