Installation | Usage | Patterns | Workflow

Requirements

• Bash 5.0+
• jq
• curl
• Go (needed for first-time installation of pup)

Bash 5+ (macOS users only)

This script requires Bash 5.0 or later.

On macOS, the default /bin/bash is too old.
Install the latest Bash with Homebrew:

brew install bash

Then, either:

• Run the script with the full path:

  /opt/homebrew/bin/bash ./nyaa-cli ...

• Or, add Homebrew Bash to your PATH (Apple Silicon):

  echo 'export PATH="/opt/homebrew/bin:$PATH"' >> ~/.zshrc
  source ~/.zshrc

  (For Intel Macs, use /usr/local/bin)

Check your Bash version:

bash --version

It should say 5.x or later

Usage

nyaa-cli :: Smart anime torrent fetcher with stateful episode tracking

Usage Patterns

The script supports four main usage patterns:

1. Continue from Last Episode (--name only)

   • Automatically continues from the last downloaded episode
   • If no previous episodes found, starts from episode 1
   • Uses state file to track progress

2. Single Episode (--episode)

   • Downloads a specific episode
   • Cannot be used with --from or --to
   • Example: --episode 120

3. From Episode to Present (--from without --to)

   • Downloads all available episodes from the starting point
   • Continues until no more episodes are found
   • Example: --from 120

4. Episode Range (--from and --to)

   • Downloads episodes within a specific range
   • --to must be greater than --from
   • Example: --from 120 --to 130

---

State Management

The script maintains a state file at ~/.local/state/nyaa-cli/progress to track the last downloaded episode for each anime. The state file is a TSV (Tab-Separated Values) file where:

• First column: Normalized anime name
• Second column: Last downloaded episode number

Example state file:

one+piece	1278
solo+leveling	18

The state is automatically updated whenever an episode is downloaded, and is used to:

• Continue from the last downloaded episode when no episode is specified
• Track progress across multiple runs
• Start from episode 1 for new anime

Example Workflow

You can use nyaa-cli to automate your anime downloads with a torrent client that supports directory watching. For example, with rtorrent, you can configure it to watch a directory for new .torrent files. When a torrent file is placed there, rtorrent will automatically start downloading it.

A typical workflow:

1. Configure your torrent client (e.g., rtorrent) to watch a directory (e.g., ~/watch/torrents).

2. Create a script to download new episodes (e.g., ~/bin/update-anime.sh):

   #!/bin/bash
   
   # Update One Piece
   nyaa-cli --name "one piece" --output ~/watch/torrents
   
   # Update Solo Leveling
   nyaa-cli --name "solo leveling" --output ~/watch/torrents

3. Make the script executable:

   chmod +x ~/bin/update-anime.sh

4. Add a weekly cronjob to run the script (e.g., every Sunday at 2 AM):

   # Edit crontab
   crontab -e
   
   # Add this line
   0 2 * * 0 ~/bin/update-anime.sh

The script will:

• Use the state file to automatically continue from the last downloaded episode
• Download new episodes if available
• Save torrent files with normalized filenames (lowercase, no spaces, no special characters)
• Your torrent client will pick up the new files and start downloading automatically

Many other torrent clients also support directory watching for automation.
