Seasonal Shift

A small CLI tool to shift season and episode numbers of TV episode files based on configurable offsets.

This is useful when episodes are downloaded with incorrect season numbering and need to be renamed and moved to the correct season folders.

The tool:

• Renames episode files
• Moves them to the correct season directory
• Shows a preview before applying changes
• Detects rename collisions
• Supports undoing the latest change
• Cleans up empty folders

---

Features

• Configurable season and episode offsets
• Preview changes before applying
• Collision detection
• Duplicate destination detection
• Undo support
• Automatic cleanup of empty season folders
• Uses XDG directories for config and state
• Written with Typer, Rich, and Pydantic

---

Installation

Install with pip:

pip install seasonal-shift

---

Configuration

By default the tool reads the config from:

~/.config/seasonal-shift/config.yaml

(or $XDG_CONFIG_HOME/seasonal-shift/config.yaml)

Example configuration:

shows:
  - name: Breaking Bad
    path: /media/shows/Breaking Bad
    seasons:
      1:
        season_offset: 2
        episode_offset: 0
      2:
        season_offset: 2
        episode_offset: 0

Meaning:

Season 1 → Season 3
Season 2 → Season 4

Episode numbering can also be shifted.

---

Directory Structure

Expected show layout:

Show Name/
  Season 1/
    Show Name - S01E01 - Episode Title.mkv
  Season 2/
    Show Name - S02E01 - Episode Title.mkv

Files must already follow a SxxExx naming pattern.

---

Usage

Preview and apply changes

seasonal-shift run

The tool will:

1. Show a preview of planned renames
2. Ask for confirmation
3. Rename and move files
4. Save an undo file

---

Use a custom config

seasonal-shift run --config my-config.yaml

---

Undo the latest change

seasonal-shift undo

Undo files are stored in:

~/.local/state/seasonal-shift/

You can also undo a specific operation:

seasonal-shift undo undo-20260310-032201.json

---

Run diagnostics

seasonal-shift doctor

This checks:

• Config validity
• Show paths
• Episode detection
• Potential rename collisions

No changes are made.

Example Preview

Breaking Bad
------------

Season 1 → 3
  Breaking Bad - S01E01 - Pilot.mkv
    → Breaking Bad - S03E01 - Pilot.mkv
  Breaking Bad - S01E02 - Cat's in the Bag.mkv
    → Breaking Bad - S03E02 - Cat's in the Bag.mkv

---

Undo System

Every run creates an undo file:

~/.local/state/seasonal-shift/undo-YYYYMMDD-HHMMSS.json

This allows reverting renames even after files are moved.
