从Java同步运行shell脚本 [英] Run shell script from Java Synchronously

问题描述

我试图执行从Java的Bash shell脚本，它使用这块code的运行正常。

I am trying to execute a Bash Shell script from Java and it runs fine using this piece of code.

public void executeScript() {
    try {
        new ProcessBuilder("myscript.sh").start();
        System.out.println("Script executed successfully");
    } catch (IOException e) {
        e.printStackTrace();
    }
}

以上code运行正常异步。但我想实现的是同步执行code。我想Java进程要等到脚本执行完毕后再执行下一批code的。

The above code runs fine asynchronously. But what I would like to achieve is to execute the code synchronously. I would like the Java process to wait until the execution of the script is completed and then execute the next batch of code.

要总结，我想打印语句 - 成功执行脚本要执行 的批处理文件（myscript.sh）完成后，执行

To summarize, I would like the "Print statement - Script executed successfully" to be executed after the batch file ("myscript.sh") completes execution.

感谢

推荐答案

您想等待进程结束，也就是<一个href=\"http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Process.html#waitFor%28%29\">waitFor()像这样

You want to wait for the Process to finish, that is waitFor() like this

public void executeScript() {
  try {
    ProcessBuilder pb = new ProcessBuilder(
      "myscript.sh");
    Process p = pb.start();     // Start the process.
    p.waitFor();                // Wait for the process to finish.
    System.out.println("Script executed successfully");
  } catch (Exception e) {
    e.printStackTrace();
  }
}
