Wordle in less than 60 lines of Bash

wordle.md

Adapted from https://gist.github.com/huytd (modified to limit possible guesses and answers and to output emoji summary at the end, to more closely resemble Josh Wardle's original game)

Lists of possible guesses and answers from https://gist.github.com/cfreshman

How to use:

1. Download list of answers from https://gist.github.com/cfreshman/a03ef2cba789d8cf00c08f767e0fad7b
2. Download list of all possible guesses from https://gist.github.com/mariecrane/661cf5d0fad7f16b52fd4f8c771d91f9
3. Download wordle.sh and make sure it's in the same directory as the two text files
4. Navigate to that directory and enter:

bash wordle.sh

wordle.sh

guesses=($(grep '^\w\w\w\w\w$' wordle-allowed-guesses-with-answers.txt | tr '[a-z]' '[A-Z]'))
solutions=($(grep '^\w\w\w\w\w$' wordle-answers-alphabetical.txt | tr '[a-z]' '[A-Z]'))
