# The Historian

> **[INCOMING — Mission Control, Earth]**
>
> Cadet, the repo in your working directory contains five commits
> from a previous mission. We need a historian's eye on it.
>
> Two commands today:
>
> - `git log --oneline` — compact one-line-per-commit history
> - `git show <hash>` — show what a commit changed
>
> Your script must produce two files:
>
> 1. `log.txt` — full one-line log
> 2. `breach-commit.txt` — short hash of the commit whose message
>    mentions `BREACH`
>
> Hint: pipe the log through `grep BREACH | awk '{print $1}'` to
> extract the short hash from the matching line.
>
> [END TRANSMISSION]

## Your Task

In `starter/starter.sh`, capture the full log and the breach commit's
short hash.

## Objectives

- `log.txt` lists all 5 commits, one per line
- `breach-commit.txt` contains the short hash of the BREACH commit
