What is the command to copy a file

What is the command to copy a file once you are in that dir?

cp oldfile newfile

thanks. I appreciate it. Is there an online manual for commands? If so, what's the URL

There are various ones depending on your os but docs.sun.com is good for Solaris info.

Don't forget the manual pages: man <I>command</I>

or search: man -k <I>keyword</I>
