We also have Sonic Pi, the popular music creation application powered by the Ruby programming language. The first of the submenus is Programming and in there we have two versions of Python: versions 2.7 and 3. The main menu is at the top left of the screen and inside there we can see a number of sub menus. In previous versions this menu was rather cluttered

The new menu has refined the way searching for applications. The Raspbian desktop has been refined to be a much more user-friendly interface by Simon Long, who joined the Raspberry Pi Foundation in late 2014, and has spent a great deal of time in creating a simple interface that does away with the repetition of applications seen in previous versions. After a few seconds the Raspbian desktop will load and you will see a clean desktop with a rather large Raspberry Pi logo. Let's now load the Raspbian desktop, to do this we use this command followed by Enter: $ startx.

If we now repeat the pwd command, it will report that we are in /home/pi/Downloads and if we wished to return to /home/pi we can type:Ī quick way to return to home is to type: It's a symbol representing the command prompt and that you should be typing in LXTerminal/Bash). We can see one called Downloads and if we want to navigate there we need to change directory, so we use the cd command and pass it the location of the directory that we wish to move to like this: $ cd Downloads (note: the ' isn't to be typed. This will output all of the directories and files in our home directory. To do this we type ls into LXTerminal, after the command prompt. This will return our location as /home/pi/ but what if we wish to navigate to another directory? If we wish to go into a directory that's in our home directory then we first need to list the directories in our home. To understand where we are in the filesystem we can use a command to print our location, which is known as print working directory by typing in $ pwd

When logged in we are dropped into our home directory and this is where all of our documents, music and pictures are held. Once logged in we are presented with the Raspbian LXTerminal and from here we have a significant amount of power available through a few common Linux commands. Every Raspberry Pi has the same default login details:
