NAME

       datalad download-url - download content

SYNOPSIS

       datalad  download-url  [-h]  [-d  PATH] [-O PATH] [-o] [--archive] [--nosave] [-m MESSAGE]
              [--version] url [url ...]

DESCRIPTION

       It allows for a uniform download interface to various supported URL schemes  (see  command
       help for details), re-using or asking for authentication details maintained by datalad.

   Examples
       Download files from an http and S3 URL::

        % datalad download-url http://example.com/file.dat s3://bucket/file2.dat

       Download a file to a path and provide a commit message::

        % datalad download-url -m 'added a file' -O myfile.dat    s3://bucket/file2.dat

       Append a trailing slash to the target path to download into a specified directory::

        % datalad download-url --path=data/ http://example.com/file.dat

       Leave off the trailing slash to download into a regular file::

        % datalad download-url --path=data http://example.com/file.dat

OPTIONS

       url    URL(s) to be downloaded. Supported protocols: 'ftp', 'http', 'https', 's3', 'shub'.
              Constraints: value must be a string

       -h, --help, --help-np
              show this help message. --help-np forcefully  disables  the  use  of  a  pager  for
              displaying the help message

       -d PATH, --dataset PATH
              specify  the dataset to add files to. If no dataset is given, an attempt is made to
              identify the dataset based on  the  current  working  directory.  Use  --nosave  to
              prevent  adding  files  to  the  dataset. Constraints: Value must be a Dataset or a
              valid identifier of a Dataset (e.g. a path) or value must be NONE

       -O PATH, --path PATH
              target for download. If the path has a trailing  separator,  it  is  treated  as  a
              directory, and each specified URL is downloaded under that directory to a base name
              taken from the URL. Without a trailing separator, the value specifies the  name  of
              the downloaded file (file name extensions inferred from the URL may be added to it,
              if they are not yet present) and only a single URL should be given. In both  cases,
              leading  directories  will  be  created  if  needed.  This argument defaults to the
              current directory. Constraints: value must be a string or value must be NONE

       -o, --overwrite
              flag to overwrite it if target file exists.

       --archive
              pass the downloaded files to datalad add-archive-content --delete.

       --nosave
              by default all modifications to a dataset are immediately saved. Giving this option
              will disable this behavior.

       -m MESSAGE, --message MESSAGE
              a  description  of  the  state or the changes made to a dataset. Constraints: value
              must be a string or value must be NONE

       --version
              show the module and its version which provides the command
