Congratulations!

You've completed Terminal for Vibe Coders and earned your certificate.

What You’ve Learned

You started this course wondering what grep -rn "TODO" src/ means. Now you can read, understand, and verify any terminal command your AI coding tool runs.

Here’s everything you covered:

  • Module 1 — Terminal basics: pwd, whoami, echo, cd, ls
  • Module 2 — File exploration: ls -la, cat, head, tail, mkdir, tree, man
  • Module 3 — Searching: find, grep, wc
  • Module 4 — File operations: cp, mv, rm, and dangerous command awareness
  • Module 5 — Pipes and redirection: |, >, >>, and power combos
  • Module 6 — Networking and permissions: curl, wget, chmod, shell scripts
  • Module 7 — Real project challenges using everything together

What’s Next?

Now that you understand the terminal:

  1. Watch your AI tools — Pay attention to the commands they run. You’ll understand them now.
  2. Ask questions — When an AI suggests a command you’re unsure about, ask it to explain.
  3. Practice — Use the Terminal Sandbox anytime to keep your skills sharp.
  4. Stay safe — Remember the red flags: rm -rf, chmod 777, -delete, --force. Always understand before you approve.

Your Graduation Gift: ShellSense

You learned to be the human in the loop. Now install ShellSense — a Claude Code hook that explains every terminal command before you approve it. It’s like having the course beside you while you work.

What ShellSense does

  • Gives you plain English explanations of every command before it runs
  • Adds risk tags — SAFE, CAUTION, or DANGEROUS — so you know at a glance
  • Catches dangerous pipes and flags destructive patterns you learned to watch for

Install with one command:

curl -fsSL https://bluesecurityops.com/downloads/shellsense.tar.gz | tar -xz -C ~/.claude/hooks/

Then add the hook to your ~/.claude/settings.json:

{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Bash",
        "hooks": [
          {
            "type": "command",
            "command": "~/.claude/hooks/shellsense/explain.sh"
          }
        ]
      }
    ]
  }
}

Or download the zip and follow the install guide.

Keep practicing in the sandbox anytime.
