🗡️ The Grand Armoury

The metallic clang of weapons echoes through the chamber. This sacred armoury teaches the essential skills of executing programs, wielding scripts, and manipulating file permissions—the true weapons of a terminal warrior.

⚡ Activation Spells: Running Executable Files

Items that end with * are executable encounters. You can activate them using a relative path:

./treasure      # Activate the treasure artifact in this room
./potion        # Consume the magickal potion

The ./ prefix is crucial. It tells the shell to look for the program in the current directory (.).

🔐 Permission Mastery: The chmod Enchantment

Sometimes, a script you create won't run. This is often because it doesn't have execute permissions. You can grant these permissions with the chmod command:

# Make a file executable
chmod +x your_script_name.sh

🏆 Armoury Forging Challenges

The artifacts in this room are not simple items; they are magickal forges that reveal powerful recipes when activated. Your challenge is to capture these recipes and turn them into usable scripts.

Challenge 1: Forge the Sword

The treasure artifact holds the recipe for a gleaming silver sword. To forge it, you must create an executable script named forge_sword.sh with a single command.

The Task:

1. Activate the ./treasure artifact.
2. Pipe its output to grep to isolate the recipe line.
3. Redirect that line into a new file, forge_sword.sh.
4. Chain a chmod +x command to make it executable.

Once forged, source ./forge_sword.sh to add the sword to your inventory.

Challenge 2: Drink the Potion

The potion artifact holds the recipe for a health-restoring elixir. To drink it, you must create an executable script named drink_potion.sh with a single command.

The Task:

1. Activate the ./potion artifact.
2. Pipe its output to grep to isolate the recipe line.
3. Redirect that line into a new file, drink_potion.sh.
4. Chain a chmod +x command to make it executable.

Once created, source ./drink_potion.sh to gain your health points.
