Java Runtime.exec() Linux Pipe

If you want to utilize Linux pipe advantages, you can do it in Java.

You may want to do the following, which is wrong.

String cmd = "ls"
Process p = Runtime.getRuntime().exec(cmd);

The correct way of executing shell command is the following:

String[] cmd = {
Process p = Runtime.getRuntime().exec(cmd);
InputStream i = p.getInputStream();
byte[] b = new byte[16];, 0, b.length); 
System.out.println(new String(b));

In this example, the program just print out the strings. But in real use, you can feed it to some complicated process.
