When a router config is saved with
copy run start IOS asks for a destination filename:
RTR#copy running-config startup-config Destination filename [startup-config]? Building configuration... [OK] To bypass the request and use the default name startup-config do this:
RTR(config)#file prompt quiet And then again
copy run start will not require the filename:
RTR#copy run start Building configuration... [OK] This command may be useful inside EEM scripts that can’t run intecartive commands.
