如何从 Java 运行脚本 [英] How to run a script from Java

问题描述

我有一个脚本，它是 Ubuntu 上的 test.sh.我想从 Java 运行它.我知道我必须使用 Runtime.getRuntime().exec();

I have a script, which is test.sh on Ubuntu. I want to run it from Java. I know I have to use Runtime.getRuntime().exec();

exec 括号里不用填test.sh 的位置吗?我正在输入 /home/main/ss/test.sh

Don't I have to fill the exec parenthesis with the location of test.sh? I am typing /home/main/ss/test.sh

我没有收到任何错误消息，但是当我搜索文件夹时，我发现该脚本不起作用.我该如何解决?

I do not get any error messages but when I searched the folder, I saw that script did not work. How can I fix it?

推荐答案

你真的应该看看 流程构建器.它真的是为这种事情而构建的.

You should really look at Process Builder. It is really built for this kind of thing.

 ProcessBuilder pb = new ProcessBuilder("myshellScript.sh", "myArg1", "myArg2");
 Map<String, String> env = pb.environment();
 env.put("VAR1", "myValue");
 env.remove("OTHERVAR");
 env.put("VAR2", env.get("VAR1") + "suffix");
 pb.directory(new File("myDir"));
 Process p = pb.start();
