如何从Java代码运行Unix shell脚本？ [英] How to run Unix shell script from Java code?

问题描述

从Java运行Unix命令非常简单。

It is quite simple to run a Unix command from Java.

Runtime.getRuntime().exec(myCommand);

但是可以从Java代码运行Unix shell脚本吗？如果是，从Java代码中运行shell脚本是一个好习惯吗？

But is it possible to run a Unix shell script from Java code? If yes, would it be a good practice to run a shell script from within Java code?

推荐答案

你应该看看< a href =http://docs.oracle.com/javase/6/docs/api/java/lang/ProcessBuilder.html =noreferrer> Process Builder 。它真的是为这种东西而构建的。

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();
