wcurl - Man Page

• Download the contents of a URL to a file indicated by the URL ("foo" in this case): wcurl https://example.com/foo
• Download the contents of a URL to a file with a specified name: wcurl [-o|--output] bar https://example.com/foo
• Download the contents of a URL, enabling progress bar and defaulting to HTTP/2: wcurl --curl-options "--progress-bar --http2" https://example.com/foo
• Resume from an interrupted download: wcurl --curl-options "--continue-at -" https://example.com/foo

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 picks 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 does:

* Percent-encode whitespaces in URLs;

* Download multiple URLs in parallel

if the installed curl's version is >= 7.66.0 (--parallel);

* Use a total number of 5 parallel connections to the same protocol + hostname + port number target

if the installed curl's version is >= 8.16.0 (--parallel-max-host);

* 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 https

if the URL does not contain any scheme;

* Disable curl's URL globbing parser

so {} and [] characters in URLs are not treated specially;

* Percent-decode the resulting filename;

* Use 'index.html' as the default filename

if there is none in the URL.

--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, 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

Don't percent-decode the output filename, even if the percent-encoding in the URL was done by wcurl, e.g.: The URL contained whitespaces.

--dry-run

Do not actually execute curl, just print what would be invoked.

-V,  --version

Print version information.

-h,  --help

Print help message.

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

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

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. The options necessary to resume the download (--clobber --continue-at -) must be the last options specified in --curl-options. Note that the only way to resume interrupted downloads is to allow wcurl to overwrite the destination file:

wcurl --curl-options="--clobber --continue-at -" example.com/filename.txt

Download multiple files without a limit of concurrent connections per host (the default limit is 5):

wcurl --curl-options="--parallel-max-host 0" example.com/filename1.txt example.com/filename2.txt
