copying disks on an Apple//e

["Andre C." <andre123@adelphia.net>]

I've had an apple//e for at least 20 years which I haven't used for at
least 15 years.
Now I've forgotten some of the commands and can't find the reference
manual. I put a disk in and it booted up the machine. Now I want to make
a copy of the disk but I forgot how.  I remember something like "copy A
to B" ( I have 2 drives) but can't remember the punctuation. Is it COPY
A: B: ? or something else. The disk is not copy protected. Can I put in
any blank 5-1/4 inch disk in drive B or do I have to intialize it first?
Also how do I do that if needed? What comes to mind is INIT. Is that
correct? Any help on these questions will be appreciated.
