"thirsty.sh" 스크립트를 작성해야 합니다: BASH [닫기]

좋아, 모든 코드가 있고 작동합니다. 난 그냥 곤경에 빠졌어while loop

#asking the user if they are "thirsty". 
echo "Are you thirsty?"


#creating thirsty variable
read thirsty


#if user answers 'no'/'No'/'NO'/'n'/'N'.
if [ "$thirsty" == "no" ] || [ "$thisrty" == "No" ] || [ "$thisrty" == "N" ] || [ "$thisrty" == "n" ] || [ "$thisrty" == "NO" ]; then
    echo "Okay, thank you for coming. Have a nice day."
    exit
fi

#if user answers 'yes'/'Yes'/'YES'/'y'/'Y'
while [ "$thirsty" != "yes" ]; do

    if [ "$thirsty" == "yes" ] || [ "$thisrty" == "Yes" ] || [ "$thisrty" == "YES" ] || [ "$thisrty" == "y" ] || [ "$thisrty" == "Y" ]; then
        echo "Okay, what would you like to drink?"
        echo "We have: water, beer, wine, and anything else you can think of."
        read drink
        if [ "$drink" == "water" ]; then
            echo "Clear crisp and refreshing"
        elif [ "$drink" == "beer" ]; then
            echo "Let me see some ID"
        elif [ "$drink" == "wine" ]; then
            echo "One box or two?"
        else 
            echo "Coming right up..."
    fi
fi

done

"예" 또는 "아니요" 중 하나에 대답하지 않으면 스크립트를 다시 시작하려면 while 루프가 필요합니다.

답변1

내가 가장 먼저 본 것은 스크립트에 "thirst"라는 단어의 철자가 여러 개 있어서 제대로 작동하지 않는다는 것입니다. "thisrty"라는 단어를 검색하고 올바른 단어 "thirst"로 바꾸세요.

또한 나중에 코드에 더 추가하고 싶은지 잘 모르겠지만 지금은 변수 값 때문에 while을 무한 루프로 바꾸고 while 뒤의 "if"를 제거할 수 있습니다. "thirst"는 다음과 같이 다시는 변하지 않습니다.

#asking the user if they are "thirsty". 
echo "Are you thirsty?"
#creating thirsty variable
read thirsty
#if user answers 'no'/'No'/'NO'/'n'/'N'.
if [ "$thirsty" == "no" ] || [ "$thirsty" == "No" ] || [ "$thirsty" == "N" ] || [ "$thirsty" == "n" ] || [ "$thirsty" == "NO" ]; then
    echo "Okay, thank you for coming. Have a nice day."
    exit
fi

while [ 1 ]; do
    echo "Okay, what would you like to drink?"
    echo "We have: water, beer, wine, and anything else you can think of."
    read drink
    if [ "$drink" == "water" ]; then
        echo "Clear crisp and refreshing"
    elif [ "$drink" == "beer" ]; then
        echo "Let me see some ID"
    elif [ "$drink" == "wine" ]; then
        echo "One box or two?"
    else 
        echo "Coming right up..."
    fi
done

답변2

사용자(플레이어?)에게 입력을 요청하는 기능을 사용하도록 코드를 변경할 수 있습니다.

is_thirsty() {
  echo """
  Are you thirsty (Yes/No)?'
  """
  while :
  do
    read -p '>' thirsty
    case ${thirsty^^} in
      NO|N)
        return 1
        ;;
      YES|Y)
        return 0
        ;;
      *)
        echo -n '(Yes/No)'
        ;;
    esac
  done
}

사용 예는 다음과 같습니다.

choose_drink() {
  echo """
  Okay, what would you like to drink?
  We have: water, beer, wine and anything else you can think of.
  """
  read -p '>' drink
  case ${drink^^} in
    WATER)
      echo "Clear crisp and refreshing"
      ;;
    BEER)
      echo "Let me see some ID"
      ;;
    WINE)
      echo "One box or two?"
      ;;
    *)
      echo "Coming right up..."
      ;;
  esac
}

goodbye() {
  echo "Okay, thank you for coming. Have a nice day."
}

is_thirsty && choose_drink || goodbye

이런 걸 찾으시는 것 같아요

# Make thirsty an uppercase variable
typeset -u thirsty

# Initialize thirsty
thirsty="INIT"

while [ "$thirsty" != "YES" || "$thirsty" != "Y" || "$thirsty" != "NO" || "$thirsty" != "N" ]
do

#asking the user if they are "thirsty". 
    echo "Are you thirsty?"


#creating thirsty variable
    read thirsty


#if user answers 'no'/'No'/'NO'/'n'/'N'.
    if [ "$thirsty" == "NO" ] || [ "$thisrty" == "N" ]; then
        echo "Okay, thank you for coming. Have a nice day."
        exit
    fi

#if user answers 'yes'/'Yes'/'YES'/'y'/'Y'
    while [ "$thirsty" != "YES" ]; do

        if [ "$thirsty" == "YES" ] || [ "$thisrty" == "Y" ]; then
            echo "Okay, what would you like to drink?"
            echo "We have: water, beer, wine, and anything else you can think of."
            read drink
            if [ "$drink" == "water" ]; then
                echo "Clear crisp and refreshing"
            elif [ "$drink" == "beer" ]; then
                echo "Let me see some ID"
            elif [ "$drink" == "wine" ]; then
                echo "One box or two?"
            else 
                echo "Coming right up..."
            fi
        fi

    done
done

한번 사용해 보고 어떻게 생각하는지 말해주세요.
