wcurl

  • a simple wrapper around curl to easily download files.

Synopsis

wcurl [--curl-options <CURL_OPTIONS>]... [--dry-run] [--] <URL>...
wcurl [--curl-options=<CURL_OPTIONS>]... [--dry-run] [--] <URL>...
wcurl -V|--version
wcurl -h|--help

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:
    • 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;
    • Disable curl's URL globbing parser so {} and [] characters in URLs are not treated specially.

Options

  • --curl-options, curl-options=<CURL_OPTIONS>...

    Specify extra options to be passed when invoking curl. May be specified more than once.

  • --dry-run

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

  • -V, --version

    Print version information.

  • -h, --help

    Print help message.

Url

Anything which is not a parameter will be considered an URL. wcurl will 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

Running the testsuite

If you would like to run the tests, you will first need to install the shunit2 package. On Debian-like and Fedora-like systems, the package is called shunit2.

After that, you can run the testsuite by simply invoking the test script:

./tests/tests.sh
