go-downloader

go-downloader is a concurrent file downloader written in Go. It allows you to download files from the internet using multiple workers, potentially speeding up the download process for large files.

Features

  • Concurrent downloading using multiple workers
  • Customizable chunk size for downloads
  • Ability to specify output file name
  • Graceful shutdown on interrupt signals

Installation

From Binary Release

  1. Go to the Releases page of the go-downloader repository.

  2. Download the latest release for your operating system and architecture:

    • Windows: Choose go-downloader-<version>-windows-<arch>.exe
    • macOS: Choose go-downloader-<version>-darwin-<arch>
    • Linux: Choose go-downloader-<version>-linux-<arch>

    Replace <version> with the latest version number and <arch> with your system architecture (amd64 for 64-bit, 386 for 32-bit, or arm64 for ARM-based systems).

  3. Make the downloaded file executable (macOS and Linux only):

    chmod +x go-downloader-<version>-<os>-<arch>

  4. Move the executable to a directory in your system's PATH. For example:

    • macOS/Linux: 
      sudo mv go-downloader-<version>-<os>-<arch> /usr/local/bin/go-downloader
      chmod +x /usr/local/bin/go-downloader

Now you can run go-downloader from anywhere in your terminal.
