我在尝试制作有趣的命令中遇到 EOF 错误。这是怎么回事？

所以，我是 Ubuntu 20.04 的新用户，我一直在尝试弄清楚如何制作自己的命令。我一直在尝试使用一系列 if-then 语句来创建一个命令，以弄清楚它们是如何工作的，但我一直遇到同样的错误。这是代码：

    echo "Would you like to see the secret? (Y/N)"
read AFFIRM
if [$AFFIRM == Y]; then
    echo "Alright, but first I need to ask a few questions. Ready? (Y/N)"
    read AFFIRM2
    if [$AFFIRM2 == Y]; then
        echo "Great. First, what is the name of this computer?"
        read COMNAME
        if [$COMNAME == thesynthetichuman -o $COMNAME == Computer X]; then
            echo "Correct! Next question: What was the name of the first user on this computer?
            read USERNAME
            if [$USERNAME == synthetichuman]; then
                echo "Correct again! Last question: What is your favorite color?"
                read FAVCOLOR
                echo $FAVCOLOR >> " eh? Nice. Here is the secret!

            else
                echo "Wrong!"
            fi
        else
            echo "Wrong!"
        fi
    

    elif [$AFFIRM == N]; then
        echo "Okay then. Bye!"

    else
        echo "Look, I had very specific instructions. Why did you ignore them? Y or N. That is it. Come on."
    fi

elif [$AFFIRM == N]; then
    echo "Okay then. Bye!"

else
    echo "Look, I had very specific instructions. Why did you ignore them? Y or N. That is it. Come on." // I seem to be getting "unexpected EOF while looking for matching `"'" errors on lines like this.

fi
echo "Bye!"
//syntax error: unexpected end of file???

我很困惑。EOF 错误出现在看似随机的行上，语法错误无论如何都会出现。我不明白如何修复错误，到目前为止我所有的谷歌搜索都是徒劳的。有人可以帮忙吗？
