linux - 小 sh 脚本错误

Question

当我运行程序并单击"is"时会引发错误:

/home/zygis/tools/script: 26: Syntax error: ")" unexpected (expecting ";;")

代码:

DIALOG=${DIALOG=dialog}

$DIALOG --title " My first dialog" --clear \
        --yesno "You really want to run this program?" 10 30

case $? in
  0)
    if [ "$1" = "start" ];
    then
            echo "Enter OS: ";
            read OS
            echo OS
            python /home/zygis/tools/dj.py $OS
    else
        if [ "$1" = "uprint" ];
        then
            echo "usage: {start}";
            echo "example: (./boot start)";
        else
            echo "Invalid choice";
            echo "To usage use uprint";
        fi
    fi
  1)
    echo "No chosen.";
  255)
    echo "ESC pressed.";

您的case/esac 的每个案例都必须由;; 终止。 See the man page...

case $? in
  0)
    if [ "$1" = "start" ];
    then
            echo "Enter OS: ";
            read OS
            echo OS
            python /home/zygis/tools/dj.py $OS
    else
        if [ "$1" = "uprint" ];
        then
            echo "usage: {start}";
            echo "example: (./boot start)";
        else
            echo "Invalid choice";
            echo "To usage use uprint";
        fi
    fi
    # Terminate.....
    ;;
  1)
    echo "No chosen.";
    # Terminate.....
    ;;
  255)
    echo "ESC pressed.";
    # Terminate.....
    ;;
