gsutil allows you to store, share and manage data hosted at cloud-based storage providers. It provides a simple Unix shell command-like syntax, operating over buckets and objects named with a URIs and wildcards. For example, the following command will retrieve all of the objects in the top-level directory of the bucket "gs://mybucket", and store them in ./local_directory:

gsutil cp gs://mybucket/* local_directory

At present gsutil works with Google Storage for Developers and Amazon's Simple Storage Service (S3).

gsutil is implemented in Python, atop the popular boto open source library. That library is included automatically when you download or check out gsutil from this site.

Note: If you just want to use gsutil (as opposed to contribute source code modifications) you can download and install from either the tar.gz or zip file.
