即語法上有效。那是你的*精確*腳本嗎？你已經錯過了使用變量的'$'，而'hashedAnswer'是一個文件名而不是散列值本身。 –

是的，這是我的確切腳本，它在第15行拋出錯誤，並且還標記「'：不是有效的標識符」「 – Defa1t

啊。該文件中有DOS行結束符。運行'dos2unix'就可以了。 –

更改這兩行：

md5sum userAnswer > hashedAnswer 
if [ answer == hashedAnswer ]

到：

hashedAnswer=$(printf "%s" "$userAnswer" |md5sum) 
if [ "$answer" == "$hashedAnswer" ]

例子：

#!/bin/bash 
# Check if you're right! 
answer="b326b5062b2f0e69046810717534cb09 -" 
echo "Enter your answer, follow by [ENTER]:" 
read userAnswer 
hashedAnswer=$(printf "%s" "$userAnswer" |md5sum) 
if [ "$answer" == "$hashedAnswer" ] 
then 
    echo "Correct! You're right! It was him! Maybe I shou----" 
    echo "-You get run over, silenced before you can present your proof-" 
else 
    echo "Wrong, try again!" 
fi

N.B：這裏的答案是true
