Script Videoverzeichnisse vergleichen und Info ausgeben
Bei der Bearbeitung von Video-Files (mkv clean, rename usw) kann es zu Fehlern kommen. Mit diesem Script lassen sich zwei Ordner vergleichen und entsprechende Infos zu der Differenz ausgeben und Fehler schneller identifizieren.

# Script: compare_folder.sh
# Author: Manuel Wendel
# Date: 2025-11-29
# Version: 2025-11-29.8
# Purpose: Compare two folder trees for common video files >10MB
# Shows count, size (MB, GB), % difference and filetype breakdown
# -----------------------------------------------------------------------------
# Changelog:
# 2025-11-29.1 Initial creation: list folder counts
# 2025-11-29.2 Added size calculation per folder
# 2025-11-29.3 Added name cleansing (remove () and {} )
# 2025-11-29.4 Color output green/red for count differences
# 2025-11-29.5 Added MB/GB columns
# 2025-11-29.6 Added % diff column, rounded to 0.01
# 2025-11-29.7 Added multiple video formats + filetype breakdown
# 2025-11-29.8 Removed quotes from filetypes, fixed header/trenner spacing
