🐯 Unit 101: Terminal Tigers

Linux Command Line Operations – Shadow Recruit Tier

Shadow Net Agency Internal Briefing > Clearance Level: RECRUIT Division: Terminal Tigers Mission Type: Covert Command-Line Operations

🕵️ Welcome, Recruit...

You've just stepped into the underground command cell of the Terminal Tigers — Shadow Net’s elite operatives who live in the shadows of the Linux terminal. They operate without GUI, without noise, and without hesitation. Every command typed is a move in the digital chessboard of espionage.

You are here because you’ve shown potential. The ability to think clearly, problem-solve under pressure, and remain unseen. Now it's time to train.

🥷🏼 What Do the Terminal Tigers Specialise In?

The Terminal Tigers are masters of the Linux Command Line Interface (CLI) — the core language of the machine. GUI tools are for the public. The terminal is for those who demand control.

In this unit, you will:

  • Navigate complex file systems silently and efficiently.
  • Hunt for hidden data and buried messages.
  • Discover how to inspect, manipulate, and defend files and directories.
  • Learn how to operate in stealth, using the most powerful tool in cybersecurity: the terminal.

Why does this matter? Because every real system we hack — from servers to routers to cybersecurity defenses — speaks the language of the terminal. And if you can master that language, you can do anything.

🪖 Your Training Path

🎖️ Mini-Missions 001–005

Each mission focuses on one core area of terminal mastery. You'll face puzzles and hidden flags. You’ll need to:

  • Use your training card for each mission.
  • Solve the challenge.
  • Submit your flag to prove your success.

Each flag earns you a badge. Collect all five before undertaking our main mission which when completed successfully will lead to you being a fully fledged Terminal Tiger Shadow Recruit and issued with a certificate!

🐯 Missions Overview

  • Mission 001: Navigating the Shadows Learn to explore the filesystem using pwd, cd, and ls.

  • Mission 002: The Whispering Files Track down a hidden file and decode its secret.

  • Mission 003: Uncover the Ghost File Use powerful search tools to locate and expose a hidden threat.

  • Mission 004: Who Has the Power? Investigate high-privilege users and uncover suspicious communications.

  • Mission 005: The Execution Key Decode file permissions and uncover a stealthy insider.

🎓 For each mission, your Training Card will prepare you. Read it carefully. Learn the techniques. Then apply them in the field.

👤 Final Mission: The Shadow Vault

Once all five missions are complete, you will be given the final Terminal Tigers operation — an all-new Shadow Net system containing multiple flags. You will need to find them all before you can call yourself a Terminal Tiger!

Only the most persistent recruits make it this far. Only the best unlock the Terminal Tigers Completion Badge and Certificate.

💡 Tip: Open each training card first. Practice the techniques in your sandbox. Then accept the final mission.
