Usage

From source file:ExecDemoLs.java

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

    final Process p; // Process tracks one external native process
    BufferedReader is; // reader for output of process
    String line;/*  w w  w  .  j av  a 2s.c o m*/

    // Optional: start a thread to wait for the process to terminate.
    // Don't just wait in main line, but here set a "done" flag and
    // use that to control the main reading loop below.
    Thread waiter = new Thread() {

    // 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.
