NEWBIE: SCRIPT HELP

[zyphonic]

How do I write a script that reads in ten numbers (either one at a time during script execution or as parameters) and prints to the screen the sum of these numbers?

How do I then alter the script to allow it to work for arbitrary lists of numbers?

THANX GUYS

bash script:

#!/bin/bash
echo `expr $1 + $2 + $3 + $4 + $5 + $6 + $7 + $8 + $9 + $10`;

pseudorandom numbers:

#!/bin/bash
echo `expr $RANDOM + $RANDOM + $RANDOM + $RANDOM + $RANDOM + $RANDOM + $RANDOM + $RANDOM + $RANDOM + $RANDOM`;

(I think)

By arbitrary I think you mean of variable length, am I correct? If you want a script that will take any number of paramaters and add them together, I would do it like this.

#!/usr/local/bin/ruby
sum = 0
ARGV.each{|i| sum+= i.to_f}
puts sum.to_s
