In Linux yo u can do a similar thing with a slight option change :
cp /home/john/* /usr/local/

Here giving a single "*" is equivalent to saying "*.*" since it is not
necessary to mention file extension in regular expressions. Of course, "*.*"
is not wrong either

For seeing all the environment variable , just type "env" on the prompt.

To set an environment variable : export MYNAME=raseel
You can also see the above by : echo $MYNAME

Hope this helps

Thanks,
