You can do something like that (assume that the two files two contain the same list of names) :
Code:
function are_same_names(n11, n12, n13, n2     ,n1) {
   n1 = n11 " " n12 " " n13;
   gsub(/ +/, " ", n1);
   return (n1 == n2)
}

BEGIN {
   FS = OFS = ":";

   while (getline < ARGV[1]) {
      f11 = $1;
      f12 = $2;
      f13 = $3;
      getline < ARGV[2];
      if (are_same_names(f11, f12, f13, $1)) {
         print f11, f12, f13, $2, $3;
      } else {
         print f11, f12, f13;
      }
   }
}

Command:
Code:
awk -f compare.awk File1 File2

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
