In Unix we seldom use *.* to denote all files. We use *. In Unix *
stands for everything :-)
Now for an example. Lets say you have a lot of files in
/usr/local/mystuff/ that you want to also have in the directory
/home/john/. You can make this happen from anywhere on the system with this:
$ sudo cp -a /usr/local/mystuff/* /home/john/
This will happen so fast you can't tell what is going on. The -a tells
cp to keep track of all the sim links and such.
