-# Count Number Of Commits On A Branch
-
-The `git rev-list` command will show all commits that fit the given revision
-criteria. By adding in the `--count` flag, we get a count of the number of
-commits that would have been displayed. Knowing this, we can get the count of
-commits for the current branch like so:
-
-```bash
-$ git rev-list --count HEAD
-4
-```
-
-This finds and counts commits from `HEAD` (usually the top of the current
-branch) all the back in reverse chronological order to the beginning of the
-branch (typically the beginning of the repository). This works exactly as
-expected for a the `main` branch.
-
-What about when we are on a feature branch though?
-
-Let's say we've branched off `main` and made a few commits. And now we want the
-count.
-
-```bash
-$ git rev-list --count HEAD
-7
-```
-
-Unfortunately, that is counting up the commits on the feature branch but it
-keeps counting all the way back to the beginning of the repo.
-
-If we want a count of just the commits on the current branch, then we can
-specify a range: from whatever `main` was when we branched to the `HEAD` of
-this branch.
-
-```bash
-$ git rev-list --count HEAD
-3
-```
-
-This is the same as saying, I want all commits on `HEAD`, but exclude (`^`) the
-commits on `main`:
-
-```bash
-git rev-list --count HEAD ^main
-3
-```
-
-See `man git-rev-list` for more details.
