It gives shell access to account, bucket, file, key, replication, listing, removal, and sync operations. ### Project history Backblaze maintains the tool in the Backblaze/B2_Command_Line_Tool repository and publishes it as a Python package, standalone binaries, Docker image, and Homebrew package. The README describes it as command-line access to all capabilities of the B2 service. The CLI has evolved across API-versioned command surfaces. The README documents the current guidance: use `b2` for the latest stable interactive interface, and use version-bound commands such as `b2v4` for long-running scripts that need stable behavior. ### Adoption history B2 users adopted the CLI because object storage needs scriptable upload, download, sync, lifecycle, and key-management workflows. Backblaze's official docs recommend Homebrew as the quickest setup path for Mac users, while the input package facts also list apk and Scoop packages. The tool is common in backup scripts and CI jobs because B2 is frequently used as low-cost object storage. Its versioned command aliases are especially package-nerdy: they let a package ship a newer implementation while preserving an older command contract for scripts. ### How it is used Typical usage starts with account authorization, then commands such as `b2 bucket list`, `b2 file upload`, `b2 ls`, `b2 sync`, and `b2 key create`. The official README and Backblaze docs state that `B2_ACCOUNT_INFO` selects the SQLite cache file for authentication information and that the default is `~/.b2_account_info`. For containers, the README shows either passing `B2_APPLICATION_KEY` and `B2_APPLICATION_KEY_ID` each run or persisting authorization state in a mounted volume. ### Why package nerds care For package nerds, `b2-tools` is a neat collision between package name, executable name, and API-versioned command names: Homebrew installs `b2-tools`, users run `b2`, and scripts may choose `b2v4` for compatibility. It is also a Python CLI with official binary and Docker distribution, so packaging choices affect startup time, dependencies, credential cache placement, and whether users get the newest API surface or a stable alias. ### Timeline - 2020: Backblaze/B2_Command_Line_Tool GitHub Releases include the 2.x release line. - 2020s: The README documents Homebrew, PyPI, standalone binaries, Docker, and source installs. - 2020s: Version-bound commands such as `b2v3` and `b2v4` become part of the CLI compatibility model. ### Related projects - Backblaze B2 Cloud Storage is the object-storage service managed by the CLI. - The B2 Native API and S3-compatible API are related service interfaces. - Backblaze's Docker image packages the same CLI for container workflows. ### Sources - Backblaze official cloud storage command-line tools docs - Backblaze/B2_Command_Line_Tool README and releases - source_facts.package-manager ## Security Notes infrastructure mutation or orchestration signal. - **Geiger risk:** orange / medium - infrastructure mutation or orchestration signal ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
