Description

wcurl is a simple curl wrapper which lets you use curl to download files without having to remember any parameters.

Simply call wcurl with a list of URLs you want to download and wcurl will pick sane defaults.

If you need anything more complex, you can provide any of curl's supported parameters via the --curl-options option. Just beware that you likely should be using curl directly if your use case is not covered.

By default, wcurl will:
• Percent-encode whitespaces in URLs;
• Download multiple URLs in parallel if the installed curl's version is >= 7.66.0;
• Follow redirects;
• Automatically choose a filename as output;
• Avoid overwriting files if the installed curl's version is >= 7.83.0 (--no-clobber);
• Perform retries;
• Set the downloaded file timestamp to the value provided by the server, if available;
• Default to the protocol used as https if the URL doesn't contain any;
• Disable curl's URL globbing parser so {} and [] characters in URLs are not treated specially;
• Percent-decode the resulting filename;
• Use "index.html" as default filename if there's none in the URL.

Options

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

-o, -O, --output, --output=<PATH>... Use the provided output path instead of getting it from the URL. If multiple URLs are provided, all files will have 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.

--dry-run Don't actually execute curl, just print what would be invoked.

-V, --version Print version information.

-h, --help Print help message.

Curl_options

Any option supported by curl can be set here. This is not used by wcurl; it's instead forwarded to the curl invocation.

Url

Anything which is not a parameter will be considered an URL. wcurl will percent-encode whitespaces and pass that to curl, which will perform the parsing of the URL.

Examples

Download a single file:
wcurl example.com/filename.txt

Download two files in parallel:
wcurl example.com/filename1.txt example.com/filename2.txt

Download a file passing the --progress-bar and --http2 flags to curl:
wcurl --curl-options="--progress-bar --http2" example.com/filename.txt

Resume from an interrupted download (if more options are used, this needs to be the last one in the list):
wcurl --curl-options="--continue-at -" example.com/filename.txt
