Code:
... | sort | 
awk '{a[++c]=$1; b[c]=$2}END{for(i=1;i<=c;i++)print a[i], b[i]/b[c]}'

Edit: should be:

Code:
... | sort | 
awk '{a[++c]=$1; b[c]+=$2}END{for(i=1;i<=c;i++)print a[i], b[i]/b[c]}'

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
