root@kali:~# wcurl -h
wcurl -- a simple wrapper around curl to easily download files.

Usage: wcurl <URL>...
       wcurl [--curl-options <CURL_OPTIONS>]... [--no-decode-filename] [-o|-O|--output <PATH>] [--dry-run] [--] <URL>...
       wcurl [--curl-options=<CURL_OPTIONS>]... [--no-decode-filename] [--output=<PATH>] [--dry-run] [--] <URL>...
       wcurl -h|--help
       wcurl -V|--version

Options:

  --curl-options <CURL_OPTIONS>: Specify extra options to be passed when invoking curl. May be
                                 specified more than once.

  -o, -O, --output <PATH>: Use the provided output path instead of getting it from the URL. If
                           multiple URLs are provided, resulting files share the same name with a
                           number appended to the end (curl >= 7.83.0). If this option is provided
                           multiple times, only the last value is considered.

  --no-decode-filename: Do not percent-decode the output filename, even if the percent-encoding in
                        the URL was done by wcurl, e.g.: The URL contained whitespace.

  --dry-run: Do not actually execute curl, just print what would be invoked.

  -V, --version: Print version information.

  -h, --help: Print this usage message.

  <CURL_OPTIONS>: Any option supported by curl can be set here. This is not used by wcurl; it is
                 instead forwarded to the curl invocation.

  <URL>: URL to be downloaded. Anything that is not a parameter is considered
         an URL. Whitespace is percent-encoded and the URL is passed to curl, which
         then performs the parsing. May be specified more than once.
