Shell 脚本 while 语句

Shell 脚本 while 语句

我正在编写一个脚本（用于教育目的），但我有点卡在这里。程序要求输入一个现有文件名并检查该文件名是否确实存在。如果不存在，则循环重复，直到您填写一个确实存在的文件。到目前为止一切顺利！但是当您输入一个确实存在的文件名时，我希望脚本进入下一个 while 循环，输入路径文件。但它没有继续。我怎样才能进入下一个 while 语句？？？

clear

echo "Your filesystem is threatned, files should be moved in order to guarantee safety!!!!"

while read FILE

do

        if [ -f $FILE ];
                then
                        echo "File is safe to secure"
                else
                        echo "Too late, we lost the file, safe another!"
fi

done


echo "Time is running out, we must secure this file inmidiately, quick give me a safe location!"



while read PATH

do

if [ -d $PATH ] && [ -f $FILE ];

        then
                echo "the location is secure! Move the file!"
        else
                echo "Either the file or the safehouse is corrupt, quick try again!"


fi

done

这有效：

clear

echo "Your filesystem is threatned, files should be moved in order to guarantee safety!!!!"

while read file; do
    if [[ -f "$file" ]]; then
        echo "File is safe to secure"
        break
    else
        echo "Too late, we lost the file, safe another!"
    fi
done

echo "Time is running out, we must secure this file inmidiately, quick give me a safe location!"

while read path; do
    if [ -d "$path" ]; then
        echo "the location is secure! Move the file!"
        break
    else
        echo "Either the file or the safehouse is corrupt, quick try again!"
    fi
done

您需要添加break语句以在找到有效文件/路径时退出循环。另外，不要使用大写字母作为变量名。
