You can run a shell on the comand line using Runtime.exec()

String[] cmdArray = new String[3];
       cmdArray[0] = "/usr/local/bin/bash";
       cmdArray[1] = "-c";
       cmdArray[2] = "pwd"; // your command

try {
           // start command running
           Process proc = Runtime.getRuntime().exec(cmdArray);

           // get command's output stream and
           // put a buffered reader input stream on it
           InputStream istr = proc.getInputStream();
           BufferedReader br = new BufferedReader(new
InputStreamReader(istr));
           try {

               // read output lines from command
               String str;
               while ((str = br.readLine()) != null) {
                   // process your results
               }
               // wait for command to terminate
               try {
                   proc.waitFor();
               }
               catch (InterruptedException ie) {
                   LOGGER.error("InterruptedException caught ", ie);
                   // possibly throw an exception here
               }

               // check its exit value
               if (proc.exitValue() != 0) {
                   InputStream errorStream = proc.getErrorStream();
                   BufferedReader brErr = new BufferedReader(new
InputStreamReader(errorStream));
                   String errStr;
                   StringBuffer errSB = new StringBuffer();
                   while ((errStr = brErr.readLine()) != null) {
                       errSB.append(errStr + "\n");
                   }
                   LOGGER.error("exit value was non-zero : \n" +
errSB.toString());
                  // possibly throw an exception here
               }
           }
           finally {
               br.close();
           }
       }
       catch (Exception ex) {
           // handle exception
       }

Hope this helps :-)
