public String execCommand(String command){
  StringBuilder buf=new StringBuilder();
  sendWaitFor(command,defaultTimeout,prompts,buf);
  log.debug(buf.toString());
  return cleanOutput(buf);
}

public String execCommand ( String command ) { StringBuilder buf = new StringBuilder ( ) ; sendWaitFor ( command , defaultTimeout , prompts , buf ) ; log . debug ( buf . toString ( ) ) ; return cleanOutput ( buf ) ; }
expectation here is that the command is less than 80 characters and is terminated by new line !
