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: cmdkit.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.

  > 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:

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

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

Resolve the value of your name:

  > ipfs name resolve
  /ipfs/QmatmE9msSfkKxoffpHwNLNKgwZG8eT9Bud6YoPab52vpy

Resolve the value of another name:

  /ipfs/QmSiTko9JZyabH56y2fussEt1A5oDqsFXB3CkvAqraFryz

		LongDescription: `
There are a number of mutable name protocols that can link among
themselves and into IPNS. For example IPNS references can (currently)
point at an IPFS object, and DNS links can point at other DNS links, IPNS
entries, or IPFS objects. This command accepts any of these
identifiers and resolves them to the referenced item.

EXAMPLES

Resolve the value of your identity:

  $ ipfs resolve /ipns/QmatmE9msSfkKxoffpHwNLNKgwZG8eT9Bud6YoPab52vpy
  /ipfs/Qmcqtw8FfrVSBaRmbWwHxt3AuySBhJLcvmFYi3Lbc4xnwj

Resolve the value of another name:

  $ ipfs resolve /ipns/QmbCMUZw6JFeZ7Wp9jkzbye3Fzp2GGcPgC3nmeUjfVF87n
  /ipns/QmatmE9msSfkKxoffpHwNLNKgwZG8eT9Bud6YoPab52vpy

Resolve the value of another name recursively:

  $ ipfs resolve -r /ipns/QmbCMUZw6JFeZ7Wp9jkzbye3Fzp2GGcPgC3nmeUjfVF87n
  /ipfs/Qmcqtw8FfrVSBaRmbWwHxt3AuySBhJLcvmFYi3Lbc4xnwj

Resolve the value of an IPFS DAG path:

  $ ipfs resolve /ipfs/QmeZy1fGbwgVSrqbfh9fKQrAWgeyRnj7h8fsHS1oy3k99x/beep/boop
  /ipfs/QmYRMjyvAiHKN9UTi8Bzt1HUspmSRD8T8DwxfSMzLgBon1
