YES.
Ah, kind of yes, kind of no.

If you are on some Unix platforms, the listener will keep writing to the listener.log even though it is deleted. It will not generate a new listener.log until you bounce the listener.

This is different than the alert.log in that the alert.log will generate a new file as soon as it needs to write something.
