public class cmd
{
        public static void main(String args[]) throws IOException
        {
                try
                {
                      String[] cmd={" /bin/bash","-c","ls -l > ls.log"};
                      Runtime.getRuntime().exec(cmd);
                }
                catch (IOException e)
                {
