    cd /Users/hdwang
    echo ls:`ls`
    
    for((i=1;i<=10;i++));

    sleep 1s
    done
    
    echo jps:`jps -l`

    public class ExecShell {
    
        public static void main(String[] args) {
    
            try {
                Process pro = Runtime.getRuntime().exec("/Users/hdwang/test.sh");
                InputStream in = pro.getInputStream();
                BufferedReader read = new BufferedReader(new InputStreamReader(in));
                String line = null;
                while((line = read.readLine())!=null){
                    System.out.println(line);
                }
    
                pro.waitFor();
    
            } catch (Exception e) {
                e.printStackTrace();
            }
