单文件 bash 脚本中的菜单及其子菜单，每个都有一个返回根目录的菜单。
我的问题是show_root_menu调用有时只是跳转到上层菜单而不是根目录。
nvidia 子菜单最常出错，返回根菜单。
show_pckg_menu当从“安装图形专有驱动程序”子菜单中选择“显示根菜单”时，它会转到“包选项” ：
到目前为止，我的其他相关问题已解决：
$ shellcheck myscript No issues detected!
实际脚本是：
#!/bin/bash

在安装程序的末尾，有四个菜单调用
show_root_menu、和show_pckg_menu，每个菜单调用都遵循相应的 case 语句。show_solver_menushow_nvidia_menu这就是发生的事情：当显示根菜单并且用户按下
cancel时，将显示包菜单。按cancel-> 求解器菜单，cancel-> nvidia 菜单，cancel-> 退出（脚本结束）。如果您再次启动脚本并按
7(nvidia menu)，然后按4返回根菜单，则 case 语句丢失并被show_pckg_menu调用。修复：仅
show_root_menu在脚本末尾调用并将 case 语句移动到它们之后的相应函数中result=$(dialog...)。
