How to Squash Multiple Commits Into One in Git

Squashing combines several commits into a single one, useful for cleaning up a feature branch's history before merging.

Key points

• The most common approach is interactive rebase: git rebase -i HEAD~N, marking all but the first commit as "squash"
• Squashing rewrites commit hashes, so avoid doing it on commits that have already been pushed and shared
• Many Git hosting platforms also offer a "squash and merge" option directly in the pull request UI

Example

git rebase -i HEAD~3
