1) This is getting a little long for the command line and should probably be put in another .sh script but:

Code:
./your_script.sh | awk -F, -vW="day,real" '
BEGIN { split(W,w,",") ; for(i in w) N[w[i]]}
{ for(word in N) if ($1 ~ word) for(i=2;i<=NF;i++) v[word,i]+=$i }
END {
   for(word in N) {
       printf "%s", word
       for(i=2; word SUBSEP i in v; i++)
           printf ",%s", v[word,i] ((i==7||i==9||i==11)?"%":"")
       printf "\n"
   }
}'

2) I think you asking for this:

Code:
./your_script.sh | awk -F, '
  NR==1 { print $0 ",NV" }
  $5==0 && $4==0.5 && $3==1 { print $0","$3-$4/($3+$5) }'

However, won't NV will always be 0.5 [ie 1 - 0.5/(1+0)]

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
