linux - 我该怎么做才能修复案例中的错误？

Question

我的代码是:

-cname)
    changeName="{2}"

    if [ -z $changeName ]; then
        echo -en "Which note name do you want to change?"
        read -r $changeName
        echo "What would you like to change the name to?"
        read -r changeNewName
    if ! [ -z "${3}" ]; then
        echo "The name has to have no spaces."
        exit 1
    fi          
    if [ -f /usr/share/cnote/notes/$changeNewName ]; then
        echo "That note name is already used. Please choose a new one."
        exit 1
    fi
    cp "/usr/share/cnote/notes/${changeName}" "/usr/share/cnote/notes/${changeNewName}"
    ;;

如果我删除我的 case 语句的这一部分，它会再次工作，但是对于那部分我会得到这个错误:root@minibian:~/cnote# ./cnote -cname./cnote: 第 73 行:意外标记附近的语法错误 ;;'
./cnote: 第 73 行: ;;'

您的第一个 if block 没有关闭。并且您不应将 $ 符号放在 changeName 之前。所以第一部分一定是

if [ -z $changeName ]; then
    echo -en "Which note name do you want to change?"
    read -r changeName
    echo "What would you like to change the name to?"
    read -r changeNewName
fi
