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

OVERVIEW.FMT(5) 						File Formats Manual						   OVERVIEW.FMT(5)

NAME

       overview.fmt - format of news overview database

DESCRIPTION

       The file <pathetc in inn.conf>/overview.fmt specifies the organization of the news overview database.  Blank lines and lines beginning with
       a number sign (``#'') are ignored.  The order of lines in this file is important; it determines the order in which the fields  will  appear
       in the database.

       Most  lines  will  consist  of  an article header name, optionally followed by a colon.	A trailing set of lines can have the word ``full''
       appear after the colon; this indicates that the header should appear as well as its value.

       If this file is changed, new overview records will be constructed with the modified format.  If it is desired to update	existing  records,
       it is necessary to rebuild the existing overview database using makehistory(8) after removing all existing overview files.

       ``Xref:full'' must be included, or innd(8) and other programs which utilize overview method cannot start.

       The default file, show below, is compatible with Geoff Collyer's ``nov'' package:
	      Subject:
	      From:
	      Date:
	      Message-ID:
	      References:
	      Bytes:
	      Lines:
	      Xref:full

       Usually the only modifications which should be made to the default file are additions of new fields to the end of the file; all such fields
       should have ``full'' after the colon.  The first eight fields should remain in the same order as above.

HISTORY

       Written by Rich $alz <rsalz@uunet.uu.net> for InterNetNews.  Intended to be compatible with  the  nov  package  written	by  Geoff  Collyer
       <geoff@world.std.com>.  This is revision 1.6.6.3, dated 2002/01/05.
