Zenity 按钮不起作用

所以我不明白为什么我的取消按钮在确认删除 zenity 框中不起作用...你能解释一下吗？

directory=$(zenity --entry \
    --text "Enter a path" \
    --title "Delete"\
    --ok-label "Done" )
    ret=$?

    if ((ret==0));then

        if [ -z "$directory" ];then #Check if user entered a path or not.
            directory=$(pwd)    #If not take the actual path.
        fi
        if [ -d "$directory" ];then #Check if entered path exist.
            Spath=$(zenity --file-selection --filename="$directory/" --title "File Browser")
            #Change the directory otherwise will not delete the wanted              file.           
            cd $directory
        fi
        if (($?==0));then
            #Check if the user really want to delete this file.
            zenity --question --icon-name "edit-delete" --title "Confirmation" --text "Are you sure you want to delete this file?"

            #Getting only the file name from the path
            Sfile=$(basename "$Spath")
            echo $?
            clear $?

问题出在这一部分，当按取消时，它遵循“确定”按钮路径。

            if (($?==0));then
                rm -f "$Sfile"  #Delete the file.
            elif (($?==1));then
                echo $?
                zenity --error --title "Info" --text "No file was deleted"
            fi      
        fi
        
    else
        #If not existing show error message.
        zenity --error --title "Error" --text "The path you entered does not exist" 
    fi

请记住，这$?意味着返回代码最后命令运行。

$?因此，如果您在运行后引用Sfile=$(basename "$Spath")，则$?表示命令的状态basename。下一个参考$?引用下一个命令。

如果你想测试zenity命令的返回码，那么你应该设置ret=$? 就在之后调用 to zenity（与您在文件开头所做的类似），然后检查$retand not的值$?。
