ipfs-pack

ipfs-pack - filesystem packing tool

ipfs-pack is a tool and library to work with ipfs and large collections of data in UNIX/POSIX filesystems.

• It identifies singular collections or bundles of data (the pack).
• It creates a light-weight cryptographically secure manifest that preserves the integrity of the collection over time, and travels with the data (PackManifest).
• It helps use ipfs in a mode that references the filesystem files directly and avoids duplicating data (filestore).
• It carries a standard dataset metadata file to capture and present information about the dataset (data-package.json).
• It helps verify the authenticity of data through a file carrying cryptographic signatures (PackAuth).

Installing

Pre-built binaries are available on the ipfs distributions page.

From source

If there is not a pre-built binary for your system, or you'd like to try out unreleased features, or for any other reason you want to build from source, its relatively simple. First, make sure you have go installed and properly configured. This guide from the go team should help with that. Once thats done, simply run make build.
