WGet Tool — Web File Downloader

Download files from HTTP/HTTPS/FTP servers with resume support, recursive downloading, bandwidth limiting, and robust error handling. Ideal for batch downloads, website mirroring, and automated data acquisition.

Quick Start

Options:
  -O, --output FILE    Save to specific filename
  -c, --continue       Resume partial download
  -q, --quiet          Suppress progress output
  --limit-rate RATE    Limit download speed (e.g., 100k, 1M)
  -r, --recursive      Download recursively
  -l, --level N        Maximum recursion depth
  --timeout SEC        Connection timeout in seconds
  --retries N          Number of retries on failure (default: 3)
  --header HEADER      Add custom HTTP header
  --user-agent UA      Custom User-Agent string
  -P, --directory-prefix DIR   Save files under directory
  --json               Output as JSON with download metadata
