# NAME

git-annex addurl - add urls to annex

# SYNOPSIS

git annex addurl `[url ...]`

# DESCRIPTION

Downloads each url to its own file, which is added to the annex.

When `yt-dlp` is installed, it can be used to check for a video
embedded in  a web page at the url, and that is added to the annex instead.
(However, this is disabled by default as it can be a security risk. 
See the documentation of annex.security.allowed-ip-addresses
in [[git-annex]](1) for details.)

Special remotes can add other special handling of particular urls. For
example, the bittorrent special remotes makes urls to torrent files
(including magnet links) download the content of the torrent,
using `aria2c`.

Normally the filename is based on the full url, so will look like
"www.example.com_dir_subdir_bigfile". In some cases, addurl is able to
come up with a better filename based on other information. Options can also
be used to get better filenames.

# OPTIONS

* `--fast`

  Avoid immediately downloading the url. The url is still checked
  (via HEAD) to verify that it exists, and to get its size if possible.

* `--relaxed`

  Don't immediately download the url, and avoid storing the size of the
  url's content. This makes git-annex accept whatever content is there
  at a future point.

  This is the fastest option, but it still has to access the network
  to check if the url contains embedded media. When adding large numbers
  of urls, using `--relaxed --raw` is much faster.

* `--verifiable` `-V`

  This can be used with the `--fast` or `--relaxed` option. It improves
  the safety of the resulting annexed file, by letting its content be
  verified with a checksum when it is transferred between git-annex
  repositories, as well as by things like `git-annex fsck`.

  When used with --relaxed, content from the web will always be accepted,
  even if it has changed, and the checksum recorded for later verification.

  When used with --fast, the checksum is recorded the first time the
  content is downloaded from the web. Once a checksum has been recorded,
  subsequent downloads from the web must have the same checksum.

  When addurl was used without this option before, the file it added 
  can be converted to be verifiable by migrating it to the VURL backend.
  For example: `git-annex migrate foo --backend=VURL`

* `--raw`

  Prevent special handling of urls by yt-dlp, and by bittorrent
  and other special remotes. This will for example, make addurl
  download the .torrent file and not the contents it points to.

* `--no-raw`

  Require content pointed to by the url to be downloaded using yt-dlp
  or a special remote, rather than the raw content of the url. if that
  cannot be done, the add will fail.

* `--raw-except=remote`

  Prevent special handling of urls by all special remotes except
  for the specified one. To allow special handling only
  by yt-dlp, use `--raw-except=web`.

* `--file=name`

  Use with a filename that does not yet exist to add a new file
  with the specified name and the content downloaded from the url.

  If the file already exists, addurl will record that it can be downloaded
  from the specified url(s).

* `--preserve-filename`

   When the web server (or torrent, etc) provides a filename, use it as-is,
   avoiding sanitizing unusual characters, or truncating it to length, or any
   other modifications.

   git-annex will still check the filename for safety, and if the filename
   has a security problem such as path traversal or a control character,
   it will refuse to add it.

* `--pathdepth=N`

  Rather than basing the filename on the whole url, this causes a path to
  be constructed, starting at the specified depth within the path of the
  url.

  For example, adding the url http://www.example.com/dir/subdir/bigfile
  with `--pathdepth=1` will use "dir/subdir/bigfile",
  while `--pathdepth=3` will use "bigfile". 

  It can also be negative; `--pathdepth=-2` will use the last
  two parts of the url.

* `--prefix=foo` `--suffix=bar`

  Use to adjust the filenames that are created by addurl. For example,
  `--suffix=.mp3` can be used to add an extension to the file.

* `--no-check-gitignore`

  By default, gitignores are honored and it will refuse to download an
  url to a file that would be ignored. This makes such files be added
  despite any ignores.

* `--jobs=N` `-JN`

  Enables parallel downloads when multiple urls are being added.
  For example: `-J4`  

  Setting this to "cpus" will run one job per CPU core.

* `--batch`

  Enables batch mode, in which lines containing urls to add are read from
  stdin.

* `-z`

  Makes the `--batch` input be delimited by nulls instead of the usual
  newlines. 

* `--with-files`

  When batch mode is enabled, makes it parse lines of the form: "$url $file"

  That adds the specified url to the specified file, downloading its
  content if the file does not yet exist; the same as
  `git annex addurl $url --file $file`

* `--json`

  Enable JSON output. This is intended to be parsed by programs that use
  git-annex. Each line of output is a JSON object.

* `--json-progress`

  Include progress objects in JSON output.

* `--json-error-messages`

  Messages that would normally be output to standard error are included in
  the JSON instead.

* `--backend`

  Specifies which key-value backend to use.

* Also the [[git-annex-common-options]](1) can be used.

# CAVEATS

If annex.largefiles is configured, and does not match a file, `git annex
addurl` will add the non-large file directly to the git repository,
instead of to the annex. However, this is not done when --fast or --relaxed
is used.
