【问题描述】：
我对这个 bat 文件的问题是我试图让最终用户选择使用 .bat 脚本阻止成人和赌博网站，我面临的问题是所有命令都一起运行，无论选择如何
有没有办法将它们分开，是否有更好的方法可以利用 C++ 程序来做到这一点？

【问题讨论】：
-
Bash 和批处理是完全不相关的语言。除了 Shebang，您还编写了一个批处理脚本。此外，标签只是路标，而不是障碍，所以没有什么可以告诉脚本不是继续前进。此外，标签不能包含空格，因此您创建了三个名为
:Changing的标签。 -
谢谢你我会改变命名我可以问你我将如何通过基本上正确地调用它来阻止它，因为我有命名错误我是正确的吗？
-
只有
goto中的第一个字符串是有效的，所以所有changing....标签都是相同的。批处理dimply逐行执行，直到达到goto、call、exit或物理文件结尾，所以它会简单地从:Changing (hosts file)运行到文件结尾，因为有在每个“部分”的末尾没有goto start。而且...标签start似乎不存在。 -
在为每个选项添加正确的命名和正确的开始和结束后现在可以使用
