Learn this by heart and you will be a successful UNIX admin.
Copiest everything exact, all files, all permissions.

And here's another example. This can be simply

 find . -exec cp -av {} <TO-DIRECTORY-PATH> \;

That was useful before rsync when you put an ssh in there:

(sleep 10; tar cf -) | ssh somewhere 'cd /here; tar xvf -'

Actually, I'm sure rsync had been released by the time I learned that
ssh pipe stuff, but it takes a while for the file-copying tricks to
synchronize over the network. :-)

Well, you could also

rsync -var . <dest>

nowadays.  rsync went and obsoleted a lot of beautiful pipe-tricks and
archive software. :-(

If rsync -a doesn't preserve enough file attributes for you, there are
moreoptions to preserve other things.

The cool thing about this is that, if you do it again later, it will
only need to copy the differences between the files.

Try it, you'll like it.

Here's a question that I seen a lot of and I' wondering what the
advantage is.

When using find, I see a lot of people using xargs when most of the time it
isn't necessary. For example, the above find sequence can be written as:

  find . -type f -maxdepth 1 -exec mv {} otherdir \;

What advantage does xargs provides in cases like this? Just wondering.

Speed through parallelism, usually.
Try it in a full directory (a newsspool comes to mind :-) )

Obviously, in this specific case, -maxdepth 1 severely restricts
the usefulness of the trick, hence the silly example.
