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.

		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

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
