Usage

From source file:ExecDemoSort.java

public static void main(String[] av) throws IOException {

    // A Runtime object has methods for dealing with the OS
    Runtime r = Runtime.getRuntime();

    // A process object tracks one external running process
    Process p;/*w  ww  .j av a2 s. co  m*/

    // file contains unsorted data
    p = r.exec("sort sortdemo.txt");

    // getInputStream gives an Input stream connected to
    // the process p's standard output (and vice versa). We use
    // that to construct a BufferedReader so we can readLine() it.
    BufferedReader is = new BufferedReader(new InputStreamReader(p.getInputStream()));

    System.out.println("Here is your sorted data:");

    String aLine;
    while ((aLine = is.readLine()) != null)
        System.out.println(aLine);

    System.out.println("That is all, folks!");

    return;
