Теперь все, с чем у меня проблемы, это утверждения «да нет». Они не позволяют вводить данные, но выглядят так же, как остальные ...

При запуске вы получите что-то вроде:
You are already running the latest version of Vault.jar.
Are you sure you want to overwrite this plugin? [Y/n]
Note: Your old plugin will be moved to the /home/pyrexiacraft/server/plugins/temp_plugins folder with todays date.
1) Yes
2) No
#? y

select ожидает, что вы введете соответствующий номер; 1 для Да или 2 для Нет в этом случае.
Тем не менее, фактическая строка, введенная пользователем, сохраняется в переменной с именем REPLY, так что вы можете анализировать ее в дополнение к числам.
Я бы просто написал функцию для вопросов да / нет; запрос да / нет не совсем то, для чего select предназначен. Что-то вроде
confirm() {
local answer
read -p "$1" -n1 answer
while [[ $answer && $answer != [YyNn] ]]; do
printf '\nPlease answer y or n\n' >&2
read -p "$1" -n1 answer
done
printf '\n'
[[ -z $answer || $answer = [Yy] ]]
}
#...
if confirm "Are you sure? [Y/n] "; then
printf 'Ok\n'
else
printf 'Fine, I will find something else to do\n'
fi
Y, y или ENTER приведут к возврату функции в true, а N или n - в функцию. Вы можете расширить его, чтобы принять значение по умолчанию в качестве второго аргумента.
