Determination n points between two coordinates

Shell Programming and Scripting

Hi guys. Can anyone tell me how to determine points between two coardinates. For example: Which type of command line gives me

50 points between (8, -5, 7) and (2, 6, 9) points

Thanks

If it has to be command line then, assuming a straight line:

echo "50 8 -5 7 2 6 9" | awk '{
    for(M=2; M<=4; M++) D[M]=$(M+3)-$M

    for(N=0; N<$1; N++)
    {
        for(M=2; M<=4; M++)
            printf(" %.2f", $M + ((N*D[M])/($1-1)));

        printf("\n");
    } }'

no formula. We have just two points and need the points among these.

oh, I thought you meant distance between 2 points, sorry!
