gs is a command line interface (CLI) and Python library that provides a set of essential commands for Google Cloud Storage. It is modeled after the AWS CLI's aws s3 command. Its features are:

• Python 3 compatibility
• A minimalistic set of dependencies
• A tiny footprint
• Intuitive convention-driven configuration of API credentials without browser login prompts
• Checksum validation to ensure end-to-end data integrity in uploads and downloads
• Progress bars for long-running upload and download operations
• Resumable uploads and downloads
• Multithreaded directory sync and batch delete, capable of handling large numbers of objects
• An attractive paging and table layout interface
• A JSON object metadata output mode for feeding data to other utilities

pip install gs

Usage:

gs [OPTIONS] COMMAND [ARGS]...

Options:

--version	Show the version and exit.
--help	Show this message and exit.

Commands:

gs configure	Set gs config options, including the API key.
gs ls	List buckets or objects in a bucket/prefix.
gs cp	Copy files to, from, or between buckets.
gs mv	Move files to, from, or between buckets.
gs mb	Create a new Google Storage bucket.
gs rb	Permanently delete an empty bucket.
gs rm	Delete objects (files) from buckets.
gs sync	Sync a directory of files with bucket/prefix.
gs api	Use httpie to perform a raw HTTP API request.
gs presign	Get a pre-signed URL for accessing an object.

Run gs configure to configure Google service account access credentials that will be used by the gs command. You can create a new service account key at https://console.cloud.google.com/iam-admin/serviceaccounts.

Before making API calls, gs ingests API credentials in the following order of priority:

• First, gs checks if a GOOGLE_APPLICATION_CREDENTIALS environment variable is set. If so, it attempts to load and use credentials from the service account credentials filename referenced by the variable.
• If that varible is not set, gs attempts to load service account credentials previously configured with gs configure (stored in ~/.config/gs/config.json).
• If that fails, gs attempts to load a service account API token from Google instance metadata.
• If that fails, gs prints a warning and attempts to make API requests anonymously.

from gs import GSClient
client = GSClient()
object_meta = client.get("b/my-bucket/o/my-object")
with client.get("b/my-bucket/o/my-object", params=dict(alt="media"), stream=True) as res:
    object_bytes = res.raw.read()
presigned_url = client.get_presigned_url("my-bucket", "my-object", expires_at=time.time()+3600)
