How do you make BCP not to display output?

I have a query that uses BCP to output results to a file. I would like to supress the results of the BCP and replace them with my own custom message. i.e I would like to replace:

NULL
Starting copy...
1000 rows successfully bulk-copied to host-file. Total received: 1000
1000 rows successfully bulk-copied to host-file. Total received: 2000
NULL
2000 rows copied.
Network packet size (bytes): 4096
Clock Time (ms.) Total     : 1719   Average : (132329.84 rows per sec.)
NULL

with

'Query executed successfully'

Thanks
