# Description:
#
# This script helps ensure that duplicate files extracted from the RAR archive are not overwritten. 
# It uses a loop to extract the log.txt file, perform modifications, and rename the file with a 
# counter to create unique filenames for each extraction. The loop continues until there are no 
# more files matching the criteria. This prevents any extracted files from being overwritten and 
# allows you to retain all versions of the extracted files.

# Description: This script demonstrates how to extract two RAR files in parallel.

# Function to extract RAR file in the background
extract_rar() {
    unrar x "$1" "$2" &   # Extract the RAR file in the background
}

# Call the function for each RAR file
extract_rar "file1.rar" "/path/to/destination1"   # Replace "file1.rar" and "/path/to/destination1" with your desired values
extract_rar "file2.rar" "/path/to/destination2"   # Replace "file2.rar" and "/path/to/destination2" with your desired values

# Wait for all background processes to finish
wait   # Wait for all the extraction processes to complete
