Pipe the numbers into sort & uniq. You will get than less since the duplicates will be deleted, but maybe you have another loop checking the count of numbers and generate some more. Maybe there is already some nice random function in Perl.

Also these lines
Quote:
number=$[ [$RANDOM % 20 ] + 1 ]
"echo $number"
did not work for me. I had to change them to
Code:
number=$(( ( $RANDOM % 20 ) + 1 ))
echo "$number"

The 1st line could be because of your shell, but the " in front of the echo seems to be a typo.

Also please use [ code ] and [ /code ] tags to make your code better visible; I edited your post to show what I mean, look for the blue background of your code.
