You can just sum it up as you go through each line:

Code:

$ cat myScript
awk '{ 
  TR=0
  for( I = 1; I <= NF; I++ ) {
    TR += $I
    TC[I] += $I
    printf( "%6d", $I )
  }
  print "  = " TR
  TF = NF
}

END {
  for( I = 1; I <= TF; I++ )
    printf "%6d", TC[I]
  print ""
}
' file

$ cat file

       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
