Thanks for that !!

Unfortunately i can't use this as

1> i do not wish to change code lines much just to get a new row...

2> i already wrote to capture exactly what i wanted....i need to tweak something somewhere to avoid my issue....

3> your code is to be run directly from command prompt where i need to put it in an engine where i m guessing it might not work....


even i had written something like this bfor..

Code:
cat /etc/group | \
nawk '
{
   ABC  = split($0, field, ":");
   USERS = split(field[4],user, ",");
   if (USERS == 0) printf "%s\t%s\t%s\n", field[1], field[3], "NULL";
   for (i = 1; i <= USERS; i++)
       printf "%s\t%s\t%s\n", field[1], field[3], user[i];
}
'

but this can be run easily from shell ,one time....my engine keeps re-iterating over DUP value....

Thanks for the effort and suggestion !!

Regards
Abhi

group

GROUP(5)						     Linux Programmer's Manual							  GROUP(5)

NAME

       group - user group file

DESCRIPTION

       The /etc/group file is a text file that defines the groups on the system.  There is one entry per line, with the following format:

	      group_name:password:GID:user_list

       The fields are as follows:

       group_name  the name of the group.

       password    the (encrypted) group password.  If this field is empty, no password is needed.

       GID	   the numeric group ID.

       user_list   a list of the usernames that are members of this group, separated by commas.

FILES

       /etc/group

BUGS

       As the 4.2BSD initgroups(3) man page says: No-one seems to keep /etc/group up-to-date.

SEE ALSO
