What is wcurl?

wcurl is a user-friendly wrapper for the curl command, specifically designed for efficient file downloads. It eliminates the need for complex curl options, allowing you to download files by simply listing their URLs. Perfect for straightforward download tasks.

Developed by Samuel Henrique, wcurl is free and open-source software.

Why Use wcurl?

The inspiration for wcurl came from Samuel Henrique's personal experience. Even as a Debian curl maintainer, he found himself struggling to remember the precise curl parameters for his preferred download settings. This led to the development of a simpler alternative.

The project was initially presented at the curl-up conference and received enthusiastic community support, leading to its collaborative development within the Debian community, involving contributions from Sergio Durigan Junior, Guilherme Puida Moreira, and Carlos Henrique Lima Melara.

Key Features of wcurl

• Effortless Usage: Simply run wcurl followed by the URLs of the files you wish to download.
• Intelligent Defaults: wcurl automatically handles URL encoding, redirect following, filename selection, retries, and sets the downloaded file's timestamp (where available).
• Customization: For advanced needs, use the --curl-options flag to specify any curl-supported parameters.
• Parallel Downloads: Download multiple files concurrently (requires curl version 7.66.0 or later).
• File Protection: Prevents overwriting existing files (requires curl version 7.83.0 or later).

wcurl Availability in Debian and Derivatives

wcurl's inclusion in Debian-based distributions:

• Debian Unstable: Available since July 2, 2024.
• Debian Testing: Expected mid-July 2024.
• Debian 12 (bookworm) backports: Available after inclusion in Debian Testing.
• Debian 12 (bookworm): Awaiting approval for inclusion in the next point release.
• Debian Derivatives: Rolling releases will receive wcurl upon its arrival in Debian Testing. Stable derivatives will include it in their next major release.

Manual Installation of wcurl on Debian Linux

wcurl requires curl. Most Linux distributions include curl by default. If not, install it using your distribution's package manager (e.g., sudo apt install curl for Debian-based systems).

1. Verify Your Distribution: Determine your Linux distribution for appropriate installation instructions.
2. Debian-based Systems (including Ubuntu): For Debian Unstable (sid), sudo apt update && sudo apt install curl should suffice (as of July 2, 2024). For Debian Testing or Stable, check for updates or proceed with manual installation. Ubuntu and other derivatives: Check your package manager for the latest curl package.
3. Manual Installation (All Linux Distributions): Download the script from GitHub or Salsa Debian, make it executable (chmod x wcurl), and move it to a directory in your PATH (e.g., /usr/local/bin/).
4. Verification: Run wcurl --version to confirm successful installation.
5. Updates: For package manager installations, use your system's update mechanism. For manual installations, repeat the download and replacement steps.

wcurl Command Examples

wcurl's usage is remarkably simple:

1. Single File Download: wcurl example.com/filename.txt
2. Parallel Downloads: wcurl example.com/file1.txt example.com/file2.txt
3. Custom curl Options: wcurl --curl-options="--progress-bar --http2" example.com/filename.txt
4. Resume Interrupted Downloads: wcurl --curl-options="--continue-at -" example.com/filename.txt
