I have to apologize, my original post is not clear enough.
I have removed my original requirement to sum fields $13 and $14 because it is adding complexity and I don't really require them for the moment.
I will try to clarify my requirement,
I have a very long list nearly 1100 lines,
Each line is very similar to these

Code:

x;x;x;x;x;x;x;x;467,390,611 Bytes;0.435291 GB;0.062247 GB;0.373045 GB;11,225;157
a;a;a;a;a;a;a;a;13,805,156,846 Bytes;12.857054 GB;1.838559 GB;11.018495 GB;151,063;18,933
b;b;b;b;b;b;b;b;232,797,478,723 Bytes;216.809547 GB;31.003765 GB;185.805782 GB;176,861;21,445;Parent: Line #545

And I need to sum all fields to obtain: the total number of bytes, and GB. (while removing those lines that contain wording "Parent: Line"

For my example the total number of bytes and gigabytes, would be something similar to:

Code:

14272547457 Bytes;13.292345 GB;1.900806 GB;11.39154 GB

I get those numbers by summing all the row of fields $9, $10, $11, $12

467,390,611 Bytes + 13,805,156,846 Bytes = 14272547457 Bytes
0.435291 GB + 12.857054 GB = 13.292345 GB
0.062247 GB + 1.838559 GB = 1.900806 GB
0.373045 GB + 11.018495 GB = 11.39154 GB

fmt

fmt(1)							      General Commands Manual							    fmt(1)

NAME

       fmt - format text

SYNOPSIS

       width] [file...]

DESCRIPTION

       The  command is a simple text formatter that fills and joins lines to produce output lines of (up to) the number of characters specified in
       the width option.  The default width is 72.  concatenates the arguments.  If none are given, formats text from the standard input.

       Blank lines are preserved in the output, as is the spacing between words.  does not fill lines beginning with a	period	for  compatibility
       with Nor does it fill lines starting with

       Indentation is preserved in the output and input lines with differing indentation are not joined (unless is used).

       can also be used as an in-line text filter for the command:

       reformats the text between the cursor location and the end of the paragraph.

   Options
       recognizes the following options:

	      Crown margin mode.
		    Preserve the indentation of the first two lines within a paragraph and align the left margin of each subsequent line with that
		    of the second line.  This is useful for tagged paragraphs.

	      Split lines only.
		    Do not join short lines to form longer ones.  This prevents sample lines of code, and other such "formatted" text, from  being
		    unduly combined.

	      Fill output lines to up to
		    width columns.

WARNINGS

       The width option is acceptable for BSD compatibility, but it may go away in future releases.
