How to use:

./wordle.sh

Or try the unlimit mode:

./wordle.sh unlimit
words=($(grep '^\w\w\w\w\w$' /usr/share/dict/words | tr '[a-z]' '[A-Z]'))
actual=${words[$[$RANDOM % ${#words[@]}]]} end=false guess_count=0 max_guess=6
if [[ $1 == "unlimit" ]]; then
max_guess=999999
fi
while [[ $end != true ]]; do
guess_count=$(( $guess_count + 1 ))
if [[ $guess_count -le $max_guess ]]; then
echo "Enter your guess ($guess_count / $max_guess):"
read guess
guess=$(echo $guess | tr '[a-z]' '[A-Z]')
if [[ " ${words[*]} " =~ " $guess " ]]; then
output="" remaining=""
if [[ $actual == $guess ]]; then
echo "You guessed right!"
for ((i = 0; i < ${#actual}; i++)); do
output+="\033[30;102m ${guess:$i:1} \033[0m"
done
printf "$output\n"
end=true
else
for ((i = 0; i < ${#actual}; i++)); do
if [[ "${actual:$i:1}" != "${guess:$i:1}" ]]; then
remaining+=${actual:$i:1}
fi
done
for ((i = 0; i < ${#actual}; i++)); do
if [[ "${actual:$i:1}" != "${guess:$i:1}" ]]; then
if [[ "$remaining" == *"${guess:$i:1}"* ]]; then
output+="\033[30;103m ${guess:$i:1} \033[0m"
remaining=${remaining/"${guess:$i:1}"/}
else
output+="\033[30;107m ${guess:$i:1} \033[0m"
fi
else
output+="\033[30;102m ${guess:$i:1} \033[0m"
fi
done
printf "$output\n"
fi
else
echo "Please enter a valid word with 5 letters!";
guess_count=$(( $guess_count - 1 ))
fi
else
echo "You lose! The word is:"
echo $actual
end=true
fi
done

I wrote a SAS version and placed it here sascommunities/wordle-sas. Uses the word lists from cfreshman (thanks) and arrays to check guesses.

I learned about this from an Oreilly blog post. Good job!
