The s/// operator is for substitution. You are telling it to replace '\d+$' with ''. Since you're trying to match the numbers and keep just them, you need to remove everything else and carry the numbers forward. Also, you need to use chomp() to remove the newline from each line.
Here is the modified code to make this work. I added an else statement at the end just to show it gives the correct result.
