Windows PowerShell (practice mode: nothing here touches your real computer)
Lesson 14: Practice: the treasure mission
Level 2, Talk to Your Computer: PowerShell. Hide a treasure, then find it again with commands. It follows lesson 13, Speed tricks. Next comes lesson 15, Level 2 test: Command Captain.
What the lesson explains
The treasure mission. Hide a treasure, then find it again, all with commands.
What you do first
Hide the treasure. In the practice terminal, type cd Downloads at the prompt PS C:\Users\you>; the prompt then reads PS C:\Users\you\Downloads>.
The files on the practice computer
This lesson works in 3 folders. At the start, your home folder, C:\Users\you holds Desktop\, Documents\, Downloads\, Pictures\; Downloads holds nothing yet; Documents holds music\, my-project\, stories\, vault\.
Along the way you type mkdir treasure and type echo "X marks the spot" > treasure\map.txt. Lesson 15 opens with the files just as you leave them.
What you practise
Mission, "Hide the treasure": In the practice terminal, type cd Downloads at the prompt PS C:\Users\you>; the prompt then reads PS C:\Users\you\Downloads>. Then: In the practice terminal, type mkdir treasure at the prompt PS C:\Users\you\Downloads> and the computer answers: Directory: C:\Users\you\Downloads / d---- treasure. It makes treasure. Then: In the practice terminal, type echo "X marks the spot" > treasure\map.txt at the prompt PS C:\Users\you\Downloads>; the prompt then reads PS C:\Users\you\Downloads>. Then: In the practice terminal, type cd ~ at the prompt PS C:\Users\you\Downloads>; the prompt then reads PS C:\Users\you>.
In your head, "Where will you be?": You are in C:\Users\you\Downloads\treasure and type cd .. — where are you now? The answer: "Downloads".
Challenge, "Find the treasure": Starting at C:\Users\you\Documents, use dir and cd to reach C:\Users\you\Downloads\treasure, then type cat there (par: 3 commands).
