Computer Loop assistance, getting array of random numbers and feeding to a command, how-to?

Hi all,
I need a little assistance to complete the following script. I would like to take a file with a single number on each line and for each number, run it through a command. The loop will terminate once all numbers have been checked. Here is what I have thus far...

Code:
COUNTER=`wc -l ~/number_list | awk '{print $1}'`
while [ $COUNTER -ne 0 ]; do
$COMMAND $NUMBER
let COUNTER=COUNTER-1
done

How do I store each number, maybe in an array? And then pass each number to the command as $NUMBER?

Thanks!

NAME
Excel::Template::Container::Loop - Excel::Template::Container::Loop PURPOSE
To provide looping NODE NAME
LOOP INHERITANCE
Excel::Template::Container ATTRIBUTES
o NAME This is the name of the loop. It's used to identify within the parameter set what variables to expose to the children nodes each iteration. CHILDREN
None EFFECTS
None DEPENDENCIES
None USAGE
<loop name="LOOPY"> ... Children here ... </loop> In the above example, the children nodes would have access to the LOOPY array of hashes as parameters. Each iteration through the array would expose a different hash of parameters to the children. These loops work just like HTML::Template's loops. (I promise I'll give more info here!) There is one difference - I prefer using Perl-like scoping, so accessing of variables outside the LOOP scope from within is perfectly acceptable. You can also hide outside variables with inner values, if you desire, just like Perl. AUTHOR
