title: How would I match a range with regex, with limited regex rules
body: <p>I have a list of items with the format abc-defg-[0000-9999].  For example, abc-defg-0904, abc-defg-0590.</p>
  
  <p>I'm trying to search and delete all of these items.</p>
  
  <p>I have these rules from the SDK I am using, but I'm not too familiar with regex, is it possible to do what I want with these rules?</p>
  
  <p>ERROR: (gcloud.compute.images.delete) Could not fetch resource:
   - Invalid value 'abc-defg-\d{4}'. Values must match the following regular expression: 'a-z?|[1-9][0-9]{0,19}'</p>
