SED/AWK to edit/add field values in a record

Hi Experts,

I am new to shell scripting. Need some help in doing one task given by the customer.

The sample record in a file is as follows:

Code:
3538,,,,,,ID,ID1,,,,,,,,,,,

It needs to be the following:

Code:
3538,,353800,353800,,,ID,ID1,,,,,COLX,,,,,COLY,

And i want to modify this record in the following manner:

1. 3rd & 4th Column should be equals to 2 zeroes at the end of the first field.
2. COLX & COLY needs to added and this value is static.

Needs to implement this using sed/awk in the most efficient way.

Thanks.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
