You would be better served to parse that, and then do the loop, rather than just evaling arbitrary strings that may include Bobby Tables, or rm -rf *

I suggest a series of simple regex:

  1. Remove everything that is not a digit, a comma or a '..'
  2. clean up leading/trailing commas and multiple commas in a row
  3. Validate (everything should in the expected form (number {comma or EOS}, or number dot-dot number {comma or EOS})
  4. split on commas
  5. For each item in the split, capture some digits followed by an optional '..' with more captured digits afterwards
  6. If there wasn't a '..', then just print $1, other wise, print $_ for $1..$2

The monks can fry your fish, and they can give you some tips and some bait, but you still need to wake up in the morning and climb onto the boat.
