First Repo

[INCOMING — Mission Control, Earth]

Cadets, your first paired exercise. One of you will set up a fresh Git project; the other will verify it. Then swap.

Pair up. Decide who goes first as defender and who goes first as attacker.

[END TRANSMISSION]

The Task

The defender writes a single shell script — setup.sh — that, when run inside an empty workspace:

1. Initializes a fresh Git repo on branch main.
2. Sets user.name and user.email on the repo.
3. Creates a file called hello-world.txt containing exactly:

   Hello, World
   

4. Stages and commits it with the message add hello-world.

Battle Rules

• Defender: writes setup.sh in a clean workspace. Does not show the file until done.
• Attacker: receives the script, runs it in a clean folder, inspects the resulting repo, and submits a review.
• Then swap: roles flip; the new defender writes their own setup.sh (no copy-pasting).
• Both pass the battle if both scripts pass review.

Tools

git init, git config, echo, >, git add, git commit -m.
