The Console Widget

You can find the console at the top of the page, superimposed on a spherical orb glowing gently in the background.

This widget is the an interface into the past, which we will use to examine and manipulate a VerticoVR system – a legacy system from at least one hundred years ago.

The widget can be toggled visible and invisible by hitting the F2 key. Try it out. Take a moment to have a complete look at the eclipsing light that apparently radiates from the celestial body somewhere off in the distance. Is it a star or a moon –- maybe an old Vertico satellite, space-station? Who knows?

Make sure to toggle your terminal back on with the F2 key so that we can return to the console. Whatever you’re looking at, no one has gazed upon it directly or indirectly for a long time. Its light is ancient by the time it reaches us.

The interface relies on typing text commands and reading the output to further commands, which the documentation and specification for is extremely limited.

In your new role as legeacy systems engineer, it is your job to make sense of all this; you may find more information on what is meant by legacy system on wikipedia.

The Command Prompt

It's important to understand the basics of reading the command prompt. Most likely you see something like this: ➜ /home/user _. This brings up three points:

1. Status: The ➜ (white color) is telling you, "This is a command prompt. I am ready to take input."

   It is worth nothing that ➜ (in green) is telling you that the entered command finished what it was instructed to do and is reporting that there was no evident problem.

   On the other hand, ➜ (in red) indicates the opposite. There was a problem, the entered command did not complete, and the reason why may or may not be evident.

2. Working Directory: The /home/user part is telling you, "You are currently located in a directory at this path; a path is an address for a file system location. It's a "folder" that you are working from and which all your commands will be influenced by.

   /home/user is the working directory. user is actually a directory which is inside of another directory, called home/, and that directory is inside /, which we call "root directory."

3. IO Stream: In order to communicate with the system, there is a stream of IO -- that is, input (user types something into the console) followed by output (system reports back based on the entered commands), that tells the user it is ready for input again. This is indicated by the white icon and the blinking purple cursor.

Perhaps this will make more sense after we try some commands.

Your First Commands

Let's try typing a command into the prompt. Scroll up to the widget at the top and type hue where you see the blinking, purple cursor. Press enter.

After that, why not try a command like sdfsdgsdgs or whatever you want; see what that does.

If the terminal fills up with too much output and you would like to clear it, use the clear command.

Trying reading the output from these commands and see if you can discover what to try.
