| They exist both.
| chop removes the last character.
| chomp removes the last character if it's newline.
Let's get this straight and correct. chomp removes the input record
separator ($/). This may or may not be a newline.
| Maybe your file has DOS-Newlines which are to characters (\r\n).
| If you chop, you keep \r at the end which could mess around with
| printing it. Perhaps you should try a double chop or something
| more sophisticated like:
chomp should handle this case correctly.
| $string =~ s/[^\da-ZA-Z-_]*$//;
That's ugly. Especially as it could be much more cleanly written as
s/(\D\W)+$//. \D is a non-digit, \W is a non-word character. Also, use +
instead of *. It's a little performance enhancer. * can match nothing, so
you could end up replacing nothing with nothing. + must match at least a
single character, so if there's nothing to replace, nothing happens.
