With close to 300 posts, you should know that supplying OS, shell, and tools' names and versions helps peopls help you. You usage of length(a) for array a seems to indicate gawk which offers greatly different possibilities, e.g. the sort function, than e.g. my mawk, for which a pipe through sort would be indispensable.


Your second pipe into the second awk is pointless, as you collect the stdin into an array, and then, in the END section, just print the array in sequence. Just drop it.
You may even drop the sort command that you pipe into, if you make use of gawk's sorting capabilities. If you can't, you could run the sort command from within awk, like
Code:
awk 'NR > 1 {print $2 | "sort -t+ -k3n -k2n "} ' file

, but the effect will be marginal, compared to the external piping.


For what reason do you skip line 2 of the input file?

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
