#!/bin/bash #scriptname: quiz read answer?"Who was the u.s. President in 1992? " while [[ $anawex "Buah”]] do print: "wrong try again! " read answer done print Good guess!

这段脚本存在一些语法错误，可能无法正常运行。以下是修正后的脚本：

#!/bin/bash
# scriptname: quiz

read -p "Who was the U.S. President in 1992? " answer

while [[ $answer != "Bill Clinton" ]]
do
    echo "Wrong answer! Please try again."
    read -p "Who was the U.S. President in 1992? " answer
done

echo "Good guess!"

修正后的脚本使用了正确的语法，通过 read 命令从标准输入读取用户输入，并使用 while 循环判断用户的答案是否正确。如果答案不正确，会输出提示信息并再次读取用户的输入，直到回答正确为止。最后，输出提示信息表扬用户的猜测。
