Regex match and grouping

Here's a sample string which I want do a regex on

101-nocola_conte_-_fuoco_fatuo_(koop_remix)

The first digit in "101" is the disc number and the next 2 digits are the track numbers. How do I match the track numbers and ignore the disc number (first digit)?

Answer

Do you mean that you don't mind what the disk number is, but you want to match, say, track number 01 ?

In perl you would match it like so: "^[0-9]01.*"
or more simply "^.01.*" - which means that you don't even mind if the first char is not a digit.
