Documentation

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 contents of <path> to ipfs. Use -r to add directories (recursively).
`,
		LongDescription: `
Adds contents of <path> to ipfs. Use -r to add directories.
Note that directories are added recursively, to form the ipfs
MerkleDAG.

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. The default is a fixed block size of
256 * 1024 bytes, 'size-262144'. Alternatively, you can use the
rabin chunker for content defined chunking by specifying
rabin-[min]-[avg]-[max] (where min/avg/max refer to the resulting
chunk sizes). Using other chunking strategies will produce
different hashes for the same file.

IPNS is a PKI namespace, where names are the hashes of public keys, and
the private key enables publishing new (signed) values. In both publish
and resolve, the default name used is the node's own PeerID,
which is the hash of its public key.

You can use the 'ipfs key' commands to list and generate more names and their
respective keys.

Examples:

Publish an <ipfs-path> with your default name:

  > ipfs name publish /ipfs/QmatmE9msSfkKxoffpHwNLNKgwZG8eT9Bud6YoPab52vpy
  Published to QmbCMUZw6JFeZ7Wp9jkzbye3Fzp2GGcPgC3nmeUjfVF87n: /ipfs/QmatmE9msSfkKxoffpHwNLNKgwZG8eT9Bud6YoPab52vpy

Publish an <ipfs-path> with another name, added by an 'ipfs key' command:

  > ipfs key gen --type=rsa --size=2048 mykey
  > ipfs name publish --key=mykey /ipfs/QmatmE9msSfkKxoffpHwNLNKgwZG8eT9Bud6YoPab52vpy

Alternatively, publish an <ipfs-path> using a valid PeerID (as listed by 
'ipfs key list -l'):

 > ipfs name publish --key=QmbCMUZw6JFeZ7Wp9jkzbye3Fzp2GGcPgC3nmeUjfVF87n /ipfs/QmatmE9msSfkKxoffpHwNLNKgwZG8eT9Bud6YoPab52vpy
