Dinesh,
You can do it from command line using the VSEManager executable. For example, to deploy a virtual service you can use the following command:
VSEManager --registry tcp://localhost:2010/Registry --username=admin --password=admin --deploy myVirtualService.mar
Keep in mind that you need to archive the virtual service prior to using the deploy command. In other words, you need to create a MAR file with all the virtual service artifacts archived in it.
