A small "Wordle" helper script
Usage: ./wordle.bash [-d] [-e <excluded characters>] [-i <required characters>] [-l <length of word>] [-p <addtional GREP pattern>]
-d Do not score duplicate letters higher.
E.g. should "eases" or "arose" score higher? "e" and "s" are very frequent letters,
but it may be disadvantageous to guess duplicate letters.
-e Exclude these letters. (The gray tiles in the original Wordle.)
-i Include/require these letters. (The yellow/green tiles in the original Wordle.)
-l Set a custom World length. (Defaults to five (5) as in the oringinal Wordle.)
-p Filter via a custom regex (GREP) pattern. Useful for the green tiles in the original Wordle.
E.g. ".r[^o].e" would imply r as the second letter and e as the last letter and o as not the third letter.
Examples:
./wordle.bash -d
