The environment variable B2_ACCOUNT_INFO specifies the sqlite file to use for caching authentication information. The default file to use is: ~/.b2_account_info

For more details on one command: b2 <command> --help

When authorizing with application keys, this tool requires that the key have the 'listBuckets' capability so that it can take the bucket names you provide on the command line and translate them into bucket IDs for the B2 Storage service. Each different command may required additional capabilities. You can find the details for each command in the help for that command.

Parallelism and the --threads parameter

Users with high performance networks, or file sets with very small files, may benefit from increased parallelism. Experiment with using the --threads parameter with small values to determine if there are benefits.

Note that using multiple threads will usually be detrimental to the other users on your network.

Contrib

bash completion

You can find a bash completion script in the contrib directory. See this for installation instructions.

detailed logs

Verbose logs to stdout can be enabled with the --verbose flag.

A hidden flag --debugLogs can be used to enable logging to a b2_cli.log file (with log rotation at midnight) in current working directory. Please take care to not launch the tool from the directory that you are syncing, or the logs will get synced to the remote server (unless that is really what you want to do).

For advanced users, a hidden option --logConfig <filename.ini> can be used to enable logging in a user-defined format and verbosity. An example log configuration can be found here.
