How to run bash from java on windows

Question

I want to execute Bash commands from within a Java program running on a Windows desktop. I installed Cygwin, and I have found the following code:

public class BashRunner {
 private static final Logger log = Logger.getLogger(BashRunner.class.getName());
 public static void run(String comand) throws IOException, InterruptedException {
 Runtime run = Runtime.getRuntime();
 String[] env = new String[] {"path=%PATH%;C:/cygwin/bin/"};
 Process proc = run.exec(new String[]{"bash.exe", comand}, env);
 proc.waitFor();
 BufferedReader br = new BufferedReader(new InputStreamReader(proc.getInputStream()));
 while (br.ready()) {
 System.out.println(br.readLine());
 }
 }
}

The problem is that the process enters an infinite loop...

The BashRunner.run(String) method is called from the main method of my program like so:

BashRunner.run("ls -alt");

• mckuok: Where does it enter an infinite loop? Does it print anything? More details please
• Gabriel Mutis: it seems like it remains stuck at this line "proc.waitFor();".... String[] env = new String[]{"Path=%PATH%;C:/cygwin/bin/"}; Process proc = run.exec(new String[]{"bash.exe", "-c" , comand}, env); so i guess at this two line i screwed up something...
