You could use Runtime.exec() method for running shell command.

Thanks everyone for replying and Sorry for not posting the code.
Heres the code :

Process p = Runtime.getRuntime().exec("rsh mac5 ps");
BufferedReader stdInput = new BufferedReader(new
InputStreamReader(p.getInputStream()));

BufferedReader stdError = new BufferedReader(new
InputStreamReader(p.getErrorStream()));

 // read the output from the command
 System.out.println("Here is the standard output of the command:
while ((s = stdInput.readLine()) != null) {
       System.out.println(s);
                }

               // read any errors from the attempted command
           System.out.println("Here is the standard error of the command (if
any):\n");
               while ((s = stdError.readLine()) != null)
           {
                  System.out.println(s);
                  }

                   System.exit(0);
           }//end of try
           catch (IOException e)
        {
              System.out.println("exception occured");
               e.printStackTrace();
              System.exit(-1);
           }

I'm able to execute rsh but i'm not getting the $ prompt .
Also ps does not execute properly its giving o/p as:
PID    TTY  TIME CMD

Thats it.
Can u tell what is the problem and where i'm going wrong???
thanks in advance.
