gawk alternative for huge file

Thanks Scottn and Danmero

Your answers wonderfully wonderfully on sample files. But I have very huge files (>7GB) with more than 150 fields. For such cases, I learnt from this forum that, I can go for gawk. Unfortunately gawk command is not present in my shell, but I have nawk.

so could you please suggest, if you find any other alternative to the above question except gawk.

Thanks Thegeek,
Could you help me in achieving the below task?
sending records with unexpected number of fields to a reject file

Cheers,
Ananda

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
