There is no need to provide sample input data file since your understanding of its composition is correct as shown from this initial post. Nevertheless, I am wondering whether if you could provide a brief one liner explanation on how your code would work since my SED knowledge is limited. Also, which of the following minor updates would accommodate for more than one surname:
I will test out each of these statements to see which one work and let you know.
Thanks again,

Hi All,
I need to select only those records having a non zero record in the first column of a comma delimited file.
Suppose my input file is having data like:
"0","01/08/2005 07:11:15",1,1,"Created",,"01/08/2005"
"0","01/08/2005 07:12:40",1,1,"Created",,"01/08/2005"... (2 Replies)

cap_mkdb
CAP_MKDB(1) BSD General Commands Manual CAP_MKDB(1)NAME
cap_mkdb -- create capability database
SYNOPSIS
cap_mkdb [-v] [-f outfile] file1 [file2 ...]
DESCRIPTION
Cap_mkdb builds a hashed database out of the getcap(3) logical database constructed by the concatenation of the specified files .
The database is named by the basename of the first file argument and the string ``.db''. The getcap(3) routines can access the database in
this form much more quickly than they can the original text file(s).
The ``tc'' capabilities of the records are expanded before the record is stored into the database.
The options as as follows:
-f outfile
Specify a different database basename.
-v Print out the number of capability records in the database.
FORMAT
Each record is stored in the database using two different types of keys.
The first type is a key which consists of the first capability of the record (not including the trailing colon (``:'')) with a data field
consisting of a special byte followed by the rest of the record. The special byte is either a 0 or 1, where a 0 means that the record is
okay, and a 1 means that there was a ``tc'' capability in the record that couldn't be expanded.
The second type is a key which consists of one of the names from the first capability of the record with a data field consisting a special
byte followed by the the first capability of the record. The special byte is a 2.
In normal operation names are looked up in the database, resulting in a key/data pair of the second type. The data field of this key/data
pair is used to look up a key/data pair of the first type which has the real data associated with the name.
RETURN VALUE
The cap_mkdb utility exits 0 on success and >0 if an error occurs.
