Java-Runtime.getRuntime().exec()发生了什么事? [英] Java - Runtime.getRuntime().exec() what's going on?

问题描述

我在Java中遇到Runtime.exec()问题 我的代码:

I have problem with Runtime.exec() in Java My code:

String lol = "/home/pc/example.txt";
String[] b = {"touch", lol}; 
try {  
    Runtime.getRuntime().exec(b);  
} catch(Exception ex) {  
    doSomething(ex);  
}

它工作正常，但是当我尝试在硬盘上不创建changle变量"lol"文件时

It's working good but when I trying changle variable "lol" files doesn't create in hard disk

例如: String lol = x.getPath();其中getPath()返回String

for instance: String lol = x.getPath(); where getPath() returns String

我该怎么办?

感谢您的回复:)

推荐答案

这是您解决问题的方法.我遇到了类似的问题，这通过指定输出目录而对我有用，它应该在该工作目录中执行文件的输出.

Here is the solution to your problem . I faced a similar problem and this worked for me by specefying the output directory, it should execute the output of your files in that working directory.

   ProcessBuilder proc = new ProcessBuilder("<YOUR_DIRECTORY_PATH>" + "abc.exe"); // <your executable path> 
   proc.redirectOutput(ProcessBuilder.Redirect.INHERIT);  // 
   proc.directory(fi); // fi = your output directory
   proc.start();
