将特殊变量(~波浪号)传递给 Java 程序 [英] Pass a special variable (~ tilde) to Java program

问题描述

我正在尝试运行一个将~"波浪号作为命令行参数的 Java 程序.不幸的是，当我运行该程序时，我得到的是我不想要的主目录打印.我不知道我怎样才能达到同样的目标?

I am trying to run a java program that takes a '~' tilde as a command line argument. Unfortunately when I run the program what I get is my home directory printed which I do not want. I am not sure how can I achieve the same ?

public class Test {

        public static void main(String[] args) {
                System.out.println(args[0]);
        }

}

推荐答案

将波浪号放在单引号中:

Put the tilde in single quotes:

java mypackage.MyClass '~'

我假设您使用的是 bash shell，在这种情况下 ~ 会自动扩展到您的主目录.将它放在单引号中告诉 shell 不要扩展它.

I'm assuming you're using the bash shell, in which case ~ is automatically expanded to your home directory. Putting it in single quotes tells the shell not to expand it.
