You seem to know that $ and ^ anchor a match to the end or the beginning of a string. So you should also know that in the absence of one of these characters, the match may start anywhere in the string. So the statement works fine as it is. However, stylistically s/[0-9]*// is better written as s/[0-9]+// because the case where no digits match is better classified as "not a match". -- The idea is that the first face shown to people is one they can readily accept - a more traditional logo.
