Hello looney,

One more query, there will be around 10 million records in source file
Yes, you could do division by
int(NR/1000000) to make only 10 files as per your requirement. You could double check it as I don't have 10 million line Input_file with me, so logic is simple like if you wanted to make 10 files just divide the total number of lines by the number of files which you need and you will get per file total number of lines then.

Do i need to close it also. ?
Yes, we do need to close the files for example
close(f) where
f is a variable for the filename.
I hope this helps you.
Thanks,
R. Singh

IGAWK(1) Utility Commands IGAWK(1)
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
