# Scalable Capital - PDF Renamer
# This script is designed to rename PDF files obtained from Scalable Capital,
# where the filenames start with a 22-character random string followed by a date and a description.
# It removes the random string, formats the date as 'YYYY-MM-DD', and adds a hyphen 
# to create a more human-readable and consistent file name.

# Example:
# Original File Name: '2fFabUoFC14sfGZCZ7FJpa 20231004 Monatlicher Kontoauszug Broker Baader Bank.pdf'
# Renamed File Name: '2023-10-04 - Monatlicher Kontoauszug Broker Baader Bank.pdf'

# Iterate through all files in the directory
for file in *; do
    # Check if it's a file
    if [ -f "$file" ]; then
        # Extract the random 22-character string from the beginning of the filename
        random_string=$(echo "$file" | grep -oE '^[[:alnum:]]{22}')
        
        # Extract the date from the remaining part of the filename
        date=$(echo "$file" | grep -oE '[0-9]{8}')
        
        # Check if both random string and date are found in the filename
        if [ -n "$random_string" ] && [ -n "$date" ]; then
            # Extract the rest of the filename without the random string and the date
            rest_of_filename=$(echo "$file" | sed "s/^$random_string //;s/ $date //" | sed 's/^[[:alnum:]]* //')
            
            # Rename the file by formatting the date and adding a hyphen between the date and the rest of the filename
            new_name="$(date -d "$date" '+%Y-%m-%d') - $rest_of_filename"
            mv "$file" "$new_name"
            
            echo "Renamed: $file -> $new_name"
