title: Regular Expression - Two Digit Range (23-79)?
body: <p>I have been reading the regex questions on this site but my issue seems to be a bit different.  I need to match a 2 digit number, such as 23 through 75.  I am doing this on an HP-UX Unix system.  I found examples of 3 - 44 but or any digit number, nothing that is fixed in length, which is a bit surprising, but perhaps I am not understand the variable length example answer.</p>
