After your gawk command, use basic shell scripting:
Code:
gawk ... file && cat del1 del2 >>final_output && rm -f del1 del2

You could use gawk in one pass, however:
Code:
gawk '\
  {
  gsub(/(^ *|^\t)/, "", $0) \\ for cutting one or more space OR tab
  }
  /^input/ {
          inputs[++in]=$0;
  }
  /^output/) {
          outputs[++out]=$0;
  }
  END { 
      print "Inputs:"
      for (x=0; x < in; ++x)
         print inputs[x];
      print "Outputs:"
      for (x=0; x < out; ++x)
         print outputs[x];
  }
}' file

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
