Correct a filename’s capitalization

Make a case-only rename that also works on Windows.

Not completed

Your task

Amend the latest local commit so Git records runbook.md instead of Runbook.md. Keep its text and keep two commits total.

What you’re aiming for

  • The tracked filename is exactly runbook.md.
  • The original text is preserved and no extra commit was added.

1. Prepare your practice folder

Use Git 2.28 or newer. The setup commands below use a Bash-compatible shell: Git Bash on Windows, or Bash on Linux/macOS.

Create a new, empty folder for this exercise. If that name already exists, choose another new name. Continue only after you’re inside the new folder.

NEW PRACTICE FOLDER
mkdir opsrung-git-rename-case-only && cd opsrung-git-rename-case-only

Run these setup commands in that folder:

SETUP — RUN ONCE
git init --initial-branch=main
git config --local user.name 'Practice Learner'
git config --local user.email 'practice@example.invalid'
printf '%s\n' 'A disposable OpsRung practice repository.' > README.txt
git add -- README.txt
git commit -m 'Start practice'
printf '%s\n' 'Start with a health check.' > Runbook.md
git add -- Runbook.md
git commit -m 'Add runbook'
Only if your personal Git settings interfere

You can normally skip this. If a commit asks for a signing key, runs a custom hook, or changes line endings unexpectedly, these repository-local overrides keep this disposable exercise independent of those settings.

OPTIONAL REPOSITORY OVERRIDES
git config --local commit.gpgsign false
git config --local core.autocrlf false
git config --local core.hooksPath .git/practice-no-hooks

Retry the failed command afterward. These settings apply only inside this practice repository.

2. Try the task

Work toward the goal above. Start by inspecting the files or resources, then use a hint if you need one.

Hint 1

Case-insensitive filesystems can hide a direct case-only rename.

Hint 2

Rename through a temporary name using git mv.

Hint 3

Amend the current commit after the rename.

3. Review your result

Use these commands to look at your result and compare it with the goals. The website does not run or verify them.

REVIEW IN YOUR TERMINAL
git status
git log --oneline --graph --all -12

What you should see

  • The tracked filename is exactly runbook.md.
  • The original text is preserved and no extra commit was added.

If your result differs: Work only in this exercise’s repository. Compare the branch, files, and history with every goal before marking complete.

Compare with one possible solution
ONE POSSIBLE SOLUTION — BASH
git mv Runbook.md temporary-runbook.md
git mv temporary-runbook.md runbook.md
git commit --amend --no-edit

Other approaches are fine if you reach the same goal. Opening this solution does not mark the exercise complete.
