Get the Command-Line Tool

Now that you have created an account, you're ready to get the command-line tool that gives easy access to all of the capabilities of B2 Cloud Storage

The B2 command-line tool is available from the Python Package Index (PyPI) using the standard pip installation tool. Your first step is to make sure that you have either Python 2 (2.6 or later) or Python 3 (3.2 or later) installed.

Installing on Mac (OSX)

You're lucky. Python is already installed by Apple. If you haven't already installed the pip installation tool, you need to install it:

1. sudo easy_install pip

Once you have Python, and the pip command, installation is simple:

1. sudo pip install --upgrade b2

If you see a message like this, it's because Apple installs a really old version of one of the Python libraries that B2 uses:

1. OSError: [Errno 1] Operation not permitted: '/tmp/pip-BMa2Su-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six-1.4.1-py2.7.egg-info'

You can work around this with the --ignore-installed option:

1. sudo pip install --upgrade --ignore-installed b2

Installing on Windows

To install Python2, pip, and the B2 command-line tool on Windows:

1. Go to Python Releases for Windows and select the "Latest Python 2 Release".
2. Download the "Windows x86-64 MSI installer" or "Windows x86 MSI installer" depending on your Windows operating system.
3. Run the installer, by default it will install Python to C:\Python27
4. Edit your PATH environment variable to include C:\Python27\;C:\Python27\Scripts\
5. Open a command window and type pip install --upgrade b2

Alternative Method

The alternative installation procedure is first make sure that you have Python installed, and then download the latest version of the source code from Github:

1. git clone https://github.com/Backblaze/B2_Command_Line_Tool.git
2. cd B2_Command_Line_Tool
3. python setup.py install

Usage

Once you have the b2 command-line tool installed, you can type "b2" on the command-line to see all of the options.

This program provides command-line access to the B2 service.
