出来while循环的shell脚本

Question

我有以下代码

echo "Please Enter the Email Id" 
while read -r email 
do 
if 
    echo "$email" | grep -v "awt" 
    then 
    echo "You entered a invalid email id please try again" 
    break 
    fi 
    echo "================You chose Email id as $email" 
done 

echo "Please Enter the user Name" 
read -r name 
    echo "you entered $name" 
echo Final email id $email 
echo final name  $name 

当IAM试图执行上面的代码，荫未能就进入第二个条件，那就是它不出来的循环。 我需要的是它应该问，直到用户输入正确的电子邮件ID之后，它应该去的下一组代码的最后打印的最后echo语句

你可以这样说：

while :; do 
    read -rp 'Please Enter the Email Id: ' email 
    if [[ $email != *awt* ]]; then 
     echo "You entered an invalid email id please try again" 
    else 
     break 
    fi 
done
