+> **[INCOMING — Mission Control, Earth]**
+>
+> Cadet, an old mission log was recovered. We need three things from it.
+>
+> When your script runs, `mission-log.txt` is sitting in the working
+> directory. Pull these out:
+>
+> 1. The first 5 lines → save to `first-five.txt`
+> 2. The last 3 lines → save to `last-three.txt`
+> 3. The total line count → save to `line-count.txt`
+>
+> Three commands:
+>
+> - `head -n N file` — first N lines
+> - `tail -n N file` — last N lines
+> - `wc -l file` — count lines
+>
+> [END TRANSMISSION]
+
