  1. 01Set the right autocrlf for macOS/Linux
  2. 02Renormalize everything via add
  3. 03Commit the normalization
Reveal the step-by-step commands

Try the terminal first — you learn more by doing. When you want to check yourself, here is the command for each step.

  1. 1. Set the right autocrlf for macOS/Linux
    git config core.autocrlf input
  2. 2. Renormalize everything via add
    git add --renormalize .
  3. 3. Commit the normalization
    git commit -m "chore: normalize line endings"

Key takeaway

Use .gitattributes (`* text=auto`) so it's per-repo, not per-machine.
