CommitCollapse – Git Commit Log Grouped by Date

CommitCollapse is a stupidly simple shell script that scans your Git commit history and prints out a clean, grouped list of what was done each day. It's the kind of summary you'd want for changelogs, weekly reports, or just understanding what happened when.

You get a list of commits under each date — no hashes, no noise, just useful text. Drop it in your repo and run it.

If you’re not in a Git repo, it’ll let you know and quit cleanly.

To use it, save the script in your repo and run:

bash CommitCollapse.sh

That’s it. A readable list of your commits by day.
