What I want is to go through this list in a selection of three.

1. After the first occurrence pattern "Processing" i have 3 lines.Save these three lines in a separate file.save the file size of this file in variable "a"

2. After 2nd occurrence of "Processing", I have 2 lines.Save these 2 lines in a separate file.save the file size of this file in variable "b"

3. After 3rd occurrence of "Processing", I have 4 lines.Save these 4 lines in a separate file.save the file size of this file in variable "c"

Now I'd perform an operation $a+$b/$c >> RESULT.txt.

Then select other triplet i.e. 4th,5th and 6th occurence of "Processing" save tyhe calculation to RESULT.txt and so on
