Git: count commits with rev-list - Adam Johnson (original) (raw)
2024-11-20
git rev-list lists details about commits (also known as “revisions”, hence the name). Its --count option outputs the count of commits in the given range. Pass it @, the short alias for HEAD, to count commits on the current branch:
$ git rev-list --count @ 707
On a branch
To count commits on a branch, specify the branch’s commit range using the <base>..<branch> syntax. For example, to count commits on the feature branch bucket that is forked off main:
$ git rev-list --count main..bucket 5
If you’re currently on the bucket branch, you can omit its name:
$ git rev-list --count main.. 5
Likewise, if you’re on main, you can omit its name:
$ git rev-list --count ..bucket 5
The opposite count is also possible: the count of commits on main not present on bucket. Just swap the branch names so bucket is first:
$ git rev-list --count bucket..main 17
It looks like bucket needs updating with a merge or rebase!
Limited time
git rev-list supports the same set of commit-limiting options as git log. For example, use --since to count commits since a certain date:
$ git rev-list --count --since yesterday 11
$ git rev-list --count --since 1.week.ago 64
Grouped by author or day
To group up counts by different dimensions, you’ll want the git shortlog command. For example, to count commits by author:
$ git shortlog -ns --since yesterday 6 Gordyn 5 Scribbles
See my previous post for more on that.

May your commits be many and your conflicts few,
