ipfs add
USAGE
ipfs add ... - Add a file or directory to ipfs.
SYNOPSIS
ipfs add [--recursive | -r] [--quiet | -q] [--quieter | -Q] [--silent] [--progress | -p] [--trickle | -t] [--only-hash | -n] [--wrap-with-directory | -w] [--hidden | -H] [--chunker= | -s] [--pin=false] [--raw-leaves] [--nocopy] [--fscache] [--cid-version=] [--hash=] [--] ...
ARGUMENTS
... - The path to a file to be added to ipfs.
OPTIONS
-r, --recursive bool - Add directory paths recursively. Default: false.
-q, --quiet bool - Write minimal output.
-Q, --quieter bool - Write only final hash.
--silent bool - Write no output.
-p, --progress bool - Stream progress data.
-t, --trickle bool - Use trickle-dag format for dag generation.
-n, --only-hash bool - Only chunk and hash - do not write to disk.
-w, --wrap-with-directory bool - Wrap files with a directory object.
-H, --hidden bool - Include files that are hidden. Only takes effect on recursive add.
-s, --chunker string - Chunking algorithm, size-[bytes] or rabin-[min]-[avg]-[max]. Default: size-262144.
--pin bool - Pin this object when adding. Default: true.
--raw-leaves bool - Use raw blocks for leaf nodes. (experimental).
--nocopy bool - Add the file using filestore. Implies raw-leaves. (experimental).
--fscache bool - Check the filestore for pre-existing blocks. (experimental).
--cid-version int - CID version. Defaults to 0 unless an option that depends on CIDv1 is passed. (experimental).
--hash string - Hash function to use. Implies CIDv1 if not sha2-256. (experimental). Default: sha2-256.
DESCRIPTION
Adds contents of 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.
