如何用参数执行命令？

Question

如何使用参数在Java中执行命令？

Process p = Runtime.getRuntime().exec(new String[]{"php","/var/www/script.php -m 2"});

不行吗？

String[] options = new String[]{"option1", "option2"};
Runtime.getRuntime().exec("command", options);

它是否也有效,因为它没有指定"m"参数.

Answer 1

看看这是否有效(抱歉现在无法测试)

Runtime.getRuntime().exec(new String[]{"php","/var/www/script.php", "-m", "2"});

Answer 2

用ProcessBuilder而不是Runtime#exec().

ProcessBuilder pb = new ProcessBuilder("php", "/var/www/script.php", "-m 2");
Process p = pb.start();
