Wordle in POSIX shell

Implementation of wordle in POSIX shell (at least I think it is POSIX compliant). Inspired by this bash implementation of the game.

Dictionary

I got the one in the repo from here.

You can use any dictionary you want (dict file). You can include any words of any size in this dictionary, but the game will only use words of length 5.

Problems

This implementation has the common problem of the "repeated characters":

• The word is times;
• The guess is abyss;
• The last s would be green (correct guess in correct place);
• The first s would be yellow (correct guess in wrong place) which isn't accurate => there is only 1 s in the target word.

It also allows you to guess complete gibberish words.
