This is how I am calculating the score of each file... splitting the filename and adding the parts and multiply it with the filesize....

Now what I am not able to do is to take files with 50 highest scores for every hour in the day ??

Code:
cd <folder>

for file in *.*
do
  
  # get the filename
  filename=$(stat -r $file | awk -F" " '{print $16}' )
  
  # get the filesize
  filesize=$(stat -r $file | awk -F" " '{print $8}' )
  
  # split the filename and store in an array
  IFS='_' read -a arr <<< "${filename}"
  
  # find the sum of the filename splitted float values
  total=0
  for i in ${arr[@]}; do
    total=`echo $total + $i | bc`;
  done

  # find the score of the file = (filesize * sum of the floats)
  score=$(echo $filesize $total | awk '{printf "%4.3f",$1*$2}')

done
