Report Rai 3 Downloader

A bash script to download content using yt-dlp and fetch associated JSON metadata with optional delay.

Requirements

• yt-dlp - for downloading content
• curl - for fetching JSON files
• bash - shell environment

Installation

1. Download the script:

   chmod +x download_script.sh
   

2. Ensure dependencies are installed:

   # Install yt-dlp
   pip install yt-dlp
   
   # curl is usually pre-installed on most systems
   

Usage

./download_script.sh -u <url> -n <name> -p <path> [-d <delay>]

Parameters

• -u <url> - Required. The URL to download (must end with .html)
• -n <name> - Required. The name for the output file
• -p <path> - Required. The directory path where files will be saved (e.g., /mnt/usb)
• -d <delay> - Optional. Delay before downloading JSON file (default: 0s)

Delay Format

The delay parameter accepts:

• s for seconds (e.g., 30s)
• m for minutes (e.g., 1m, 5m)
• h for hours (e.g., 2h)

Examples

Basic usage (no delay)

./download_script.sh -u "https://example.com/video.html" -n "my_video" -p "/mnt/usb"

With 30 seconds delay

./download_script.sh -u "https://example.com/video.html" -n "my_video" -p "/mnt/usb" -d 30s

With 1 minute delay

./download_script.sh -u "https://example.com/video.html" -n "my_video" -p "/mnt/usb" -d 1m

With 2 hours delay

./download_script.sh -u "https://example.com/video.html" -n "my_video" -p "/mnt/usb" -d 2h

Flags in different order

./download_script.sh -p "/home/user/downloads" -d 1m -n "video" -u "https://example.com/content.html"

How It Works

1. Downloads the content from the specified URL using yt-dlp
2. Saves it with the provided name in the specified path
3. Waits for the specified delay (if provided)
4. Converts the URL from .html to .json (e.g., video.html → video.json)
5. Downloads the JSON file using curl
6. Saves the JSON with the same name plus .json extension

Output

The script creates two files in the specified path:

• <name> - The downloaded content
• <name>.json - The associated JSON metadata

Error Handling

• The script validates that all required parameters are provided
• Checks if the specified path exists before downloading
• Displays clear error messages if something goes wrong

Notes

• The script assumes the JSON endpoint follows the pattern: replacing .html with .json
• The path must exist before running the script
• Perfect for downloading to mounted USB drives or network shares
