how to pass Y/N in bat file

Hi guys

I need help to pass Y/N in bat file to download file from website using bat file..

when i am running the bat file from data services, i am getting to pass Y/N to continue with the downloading file from website..

see the details below:-

If you trust this host, press Yes. To connect without adding host key to the cache, press No. To abandon the connection press Cancel.  In scripting, you should use a -hostkey switch to configure the

expected host key.  (Y)es, (N)o, C(a)ncel (10 s), (C)opy Key: Cancel

Please tell me how to pass Y by default in bat file.. so that when it runs bat file should pass Y to accept the trusted host..

Thanks for your help
