AWS CLI on Mac

There's a handy (and official) command line interface tool for dealing with AWS. It's great for managing files with S3.

Here's a short guide, somewhat from memory. Please improve this if you encounter any issues:

1. Install AWS cli via homebrew
2. Configure the AWS client (you need to add credentials for accessing the service)

Refer to this post Show archive.org snapshot for information on how to do this.

After that, you can do things like:

aws s3 sync s3://source_bucket s3://destination_bucket

There's lots more you can do, use the inline help as suggested by the article linked above.
