Getting Started with the Raspberry Pi Zero Wireless
Now that you've gotten your board up and running let's go over some basics.
Raspbian and most Raspberry Pi OSes are going to be Linux based. Don't let that scare you too much. Gone are the days of having to remember lots of commands or that you need to type
:wq to save and exit your text editor. Linux now a days has a Graphical User Interface (GUI) similar to Windows or MacOS, and, while you will probably want to learn a few basic commands and shorcuts, you can usually get away with not using them.
In the upper left hand corner of Raspbian you will see six icons. The first is a Raspberry. This is basically the same as your 'Start Menu' on Windows machines. Click on this, and you will see a menu of all the installed programs as well as the shutdown options. The second icon looks like a globe, and it is the Web Browser. Then we have the "File Manager", "Terminal", "Mathematica", and finally "Wolfram".
Changing Your Password
An important thing to remember is that Linux has user names and passwords. The default Raspian user id is "pi" and the password is "raspberry". The second thing to remember is that I know your user id and password and so do lots of other people with less honorable intentions. Don't assume all viruses are written for full sized computers. Raspberry Pis tend to have a reasonable amount of processing power and are often left running wtih very little to do. Recently viruses have been showing up that were written specifically to log into Raspberry Pis using the default user name and password and use their processing power to mine crypto currencies.
So, the first thing we are going to do is change the password. Open up a terminal window and type
pi@raspberrypi : ~ $ sudo passwd
You will be prompted to enter your new password. Type in your new password, and your Pi will be that much more secure from unwanted visitors.
