Plex Library Scanner Implementation Summary

Overview

Successfully implemented a comprehensive Plex library scanning solution based on the Plex Media Scanner CLI documentation. The implementation provides both standalone functionality and seamless integration with the existing plex.sh management script.

Implementation Details

1. New Script: scan-plex-libraries.sh

Location: /home/acedanger/shell/plex/scan-plex-libraries.sh

Features Implemented:

• ✅ Library Listing: Lists all Plex libraries with section IDs and names
• ✅ Library Scanning: Scan for new media (individual or all libraries)
• ✅ Metadata Refresh: Refresh library metadata with force option
• ✅ Media Analysis: Analyze media files (standard and deep analysis)
• ✅ Thumbnail Generation: Generate thumbnails and fanart
• ✅ Library Tree: Display hierarchical library structure
• ✅ Interactive Mode: User-friendly menu system
• ✅ Verbose Logging: Detailed operation logging
• ✅ Error Handling: Comprehensive validation and error reporting
• ✅ Service Validation: Checks Plex service status before operations
• ✅ Scanner Detection: Automatically finds Plex Media Scanner binary

Command Examples:

# List all libraries
./scan-plex-libraries.sh list

# Scan specific library
./scan-plex-libraries.sh scan 29

# Force refresh all libraries
./scan-plex-libraries.sh refresh "" true

# Deep analyze specific library
./scan-plex-libraries.sh analyze 29 true

# Generate thumbnails for library
./scan-plex-libraries.sh generate 29

# Interactive mode
./scan-plex-libraries.sh

2. Integration with plex.sh

Changes Made:

• ✅ Added scan command to main case statement
• ✅ Added launch_scanner() function for integration
• ✅ Updated help documentation to include scan command
• ✅ Updated script header documentation
• ✅ Supports argument passthrough to scanner script

Integration Examples:

# Launch interactive scanner
./plex.sh scan

# Pass commands directly to scanner
./plex.sh scan list
./plex.sh scan scan 29
./plex.sh scan refresh "" true

3. New Aliases

Added to /home/acedanger/shell/dotfiles/my-aliases.zsh:

alias plex-scan="/home/acedanger/shell/plex/plex.sh scan"        # Library scanner via plex.sh
alias plex-scanner="/home/acedanger/shell/plex/scan-plex-libraries.sh"  # Direct scanner access

Usage Examples:

plex-scan              # Launch scanner via plex.sh
plex-scanner list      # Direct scanner access to list libraries
plex-scanner scan 29   # Direct scan of specific library

4. Documentation

Created:

• ✅ Comprehensive Documentation: /home/acedanger/shell/plex/docs/plex-library-scanner.md
• ✅ Updated Main README: Added scanner section to /home/acedanger/shell/plex/README.md

Documentation Includes:

• Complete usage guide with examples
• Command reference with parameters
• Integration examples
• Troubleshooting guide
• Best practices
• Performance considerations

Key Features

Automatic Scanner Detection

The script automatically detects the Plex Media Scanner binary from common locations:

• /usr/lib/plexmediaserver/Plex Media Scanner (Linux - most common)
• /opt/plex/Plex Media Scanner
• /usr/local/plex/Plex Media Scanner
• /Applications/Plex Media Server.app/Contents/MacOS/Plex Media Scanner (macOS)
• System PATH

Comprehensive Error Handling

• Service status validation (Plex must be running)
• Scanner binary detection and validation
• Section ID validation against actual libraries
• Operation failure detection and reporting
• Graceful error recovery

Interactive Mode

Full-featured interactive menu system with:

• Library listing and selection
• Operation choice with sub-menus
• Force/deep options for advanced operations
• User-friendly prompts and confirmations

Logging and Debugging

• Detailed logging to /home/acedanger/shell/logs/plex-scanner.log
• Verbose mode for debugging (-v flag)
• Timestamp-based log entries
• Operation success/failure tracking

Based on Plex CLI Documentation

Implementation follows the official Plex Media Scanner CLI documentation:

• Uses standard Plex scanner commands (--list, --scan, --refresh, etc.)
• Proper section ID handling
• Force flags for metadata refresh
• Deep analysis options
• Thumbnail generation capabilities

Testing Results

✅ Syntax Validation

$ bash -n ./scan-plex-libraries.sh
$ bash -n ./plex.sh
# Both scripts pass syntax validation

✅ Help System

$ ./plex.sh help
# Shows new scan command in help output

$ ./scan-plex-libraries.sh --help
# Shows comprehensive usage information

✅ Error Handling

$ ./scan-plex-libraries.sh list
# Correctly detects Plex service not running
# Provides helpful error message with resolution

✅ Integration

$ ./plex.sh scan --help
# Successfully launches scanner with arguments
# Proper argument passthrough working

Usage Workflow

Basic Operations

# List all libraries
plex-scanner list

# Scan all libraries for new media
plex-scanner scan

# Scan specific library
plex-scanner scan 29

# Force refresh specific library
plex-scanner refresh 29 true

Via plex.sh Integration

# Interactive scanner
plex scan

# Quick library list
plex scan list

# Quick scan of all libraries
plex scan scan
