Bash 腳本不會在 ctrl d 上退出

Question

我正在編寫一個簡單的 bash 腳本，根據我的作業規範，它將在 ctrl-d 上終止。然而，它並沒有這樣做，它只是停止讀取當前輸入並開始讀取下一個輸入。我該如何解決這個問題？這是我的腳本：

while true ; do
echo Please enter your full name:
read fullName
echo Please enter your street addres:
read streetAddress
echo Please enter your zip code, city, and state in that order:
read zip city state

echo $fullName > Name.txt
echo "$streetAddress  $city  $state  $zip" >> Locations.txt
echo $fullName >> "$zip".txt
echo $streetAddress >> "$zip".txt
echo "$city  $state  $zip" >> "$zip".txt
echo '' >> "$zip".txt
done

Answer 1

您可以從命令中檢查退出代碼read。

if [[ $? != 0 ]]; then
    echo "Exiting"
    exit 1
fi

Answer 2

以下是我如何實現所需的行為：

notFinished=true
while $notFinished ; do
    echo Please enter your full name:
    while read fullName ; do
        echo Please enter your street addres:
        read streetAddress
        echo Please enter your zip code, city, and state in that order:
        read zip city state

        echo $fullName > Name.txt
        echo "$streetAddress  $city  $state  $zip" >> Locations.txt
        echo $fullName >> "$zip".txt
        echo $streetAddress >> "$zip".txt
        echo "$city  $state  $zip" >> "$zip".txt
        echo '' >> "$zip".txt
        continue 2
    done
    notFinished=false
done

現在，當我按下 control-d 時，應用程式將按預期退出。
