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. 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
Rabin fingerprint chunker for content defined chunking by specifying
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

of consistency guarantees. If the daemon is unexpectedly killed before running

applies to running 'ipfs repo gc' concurrently with '--flush=false'
