msSync is a small utility that uploads files from a folder on your computer to Google Cloud Storage. It exists to solve a specific frustration: Google's own command-line tool for this task, gsutil, makes it awkward to switch between different Google Cloud accounts using credential files. If you work with multiple Google Cloud projects and need to upload files to each one, this script lets you point to the exact credentials file you want to use each time, sidestepping that headache. Running it is straightforward. From a command line, you tell it three things: the name of the destination bucket, the folder you want to upload, and the path to a credentials file. The script then handles the upload, using that specific credentials file to authenticate with Google Cloud Storage. It is a lightweight, purpose-built tool rather than a full-featured application. This would be useful for anyone who juggles multiple Google Cloud accounts, a freelancer managing separate projects for different clients, a developer bouncing between staging and production environments, or anyone who has hit the same wall with gsutil's authentication. Rather than wrestling with Google's tool every time you need to switch accounts, you just pass the right key file and go. The project makes no pretense of being anything grand. The author openly describes it as a "worthless script," meaning it is a quick personal utility built to scratch a specific itch rather than a polished product. The README does not go into detail about installation steps beyond the basic usage command, performance characteristics, or whether it syncs in both directions. It appears to be a one-way upload tool, plain and simple, shared in case others find themselves equally frustrated with the official options.
