Overview ¶
Package commands implements the ipfs command interface
Using github.com/ipfs/go-ipfs/commands to define the command line and HTTP APIs. This is the interface available to folks using IPFS from outside of the Go language.

var AddCmd = &cmds.Command{ Helptext: cmds.HelpText{ Tagline: "Add a file or directory to IPFS.", ShortDescription: ` Adds the content of <path> to IPFS. Use -r to add directories (recursively). `, LongDescription: ` Adds the content of <path> to IPFS. Use -r to add directories. Note that directories are added recursively, to form the IPFS MerkleDAG. If the daemon is not running, it will just add locally. If the daemon is started later, it will be advertised after a few seconds when the reprovider runs. The wrap option, '-w', wraps the file (or files, if using the recursive option) in a directory. This directory contains only the files which have been added, and means that the file retains its filename. For example: > ipfs add example.jpg added QmbFMke1KXqnYyBBWxB74N4c5SBnJMVAiMNRcGu6x1AwQH example.jpg > ipfs add example.jpg -w added QmbFMke1KXqnYyBBWxB74N4c5SBnJMVAiMNRcGu6x1AwQH example.jpg added QmaG4FuMqEBnQNn3C8XJ5bpW8kLs7zq2ZXgHptJHbKDDVx You can now refer to the added file in a gateway, like so: /ipfs/QmaG4FuMqEBnQNn3C8XJ5bpW8kLs7zq2ZXgHptJHbKDDVx/example.jpg The chunker option, '-s', specifies the chunking strategy that dictates how to break files into blocks. Blocks with same content can be deduplicated. Different chunking strategies will produce different hashes for the same file. The default is a fixed block size of 256 * 1024 bytes, 'size-262144'. Alternatively, you can use the Buzhash or Rabin fingerprint chunker for content defined chunking by specifying buzhash or rabin-[min]-[avg]-[max] (where min/avg/max refer to the desired chunk sizes in bytes), e.g. 'rabin-262144-524288-1048576'. The following examples use very small byte sizes to demonstrate the properties of the different chunkers on a small file. You'll likely want to use a 1024 times larger chunk sizes for most files. > ipfs add --chunker=size-2048 ipfs-logo.svg added QmafrLBfzRLV4XSH1XcaMMeaXEUhDJjmtDfsYU95TrWG87 ipfs-logo.svg > ipfs add --chunker=rabin-512-1024-2048 ipfs-logo.svg added Qmf1hDN65tR55Ubh2RN1FPxr69xq3giVBz1KApsresY8Gn ipfs-logo.svg You can now check what blocks have been created by: > ipfs object links QmafrLBfzRLV4XSH1XcaMMeaXEUhDJjmtDfsYU95TrWG87 QmY6yj1GsermExDXoosVE3aSPxdMNYr6aKuw3nA8LoWPRS 2059 Qmf7ZQeSxq2fJVJbCmgTrLLVN9tDR9Wy5k75DxQKuz5Gyt 1195 > ipfs object links Qmf1hDN65tR55Ubh2RN1FPxr69xq3giVBz1KApsresY8Gn QmY6yj1GsermExDXoosVE3aSPxdMNYr6aKuw3nA8LoWPRS 2059 QmerURi9k4XzKCaaPbsK6BL5pMEjF7PGphjDvkkjDtsVf3 868 QmQB28iwSriSUSMqG2nXDTLtdPHgWb4rebBrU7Q1j4vxPv 338 Finally, a note on hash determinism.

The files facility interacts with MFS (Mutable File System). MFS acts as a single, dynamic filesystem mount. MFS has a root CID that is transparently updated when a change happens (and can be checked with "ipfs files stat /"). All files and folders within MFS are respected and will not be deleted during garbage collections. However, a DAG may be referenced in MFS without being fully available locally (MFS content is lazy loaded when accessed). MFS is independent from the list of pinned items ("ipfs pin ls"). Calls to "ipfs pin add" and "ipfs pin rm" will add and remove pins independently of MFS. If MFS content that was additionally pinned is removed by calling "ipfs files rm", it will still remain pinned. Content added with "ipfs add" (which by default also becomes pinned), is not added to MFS. Any content can be lazily referenced from MFS with the command "ipfs files cp /ipfs/<cid> /some/path/" (see ipfs files cp --help).
