# 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.
