+# List Commits On A Branch
+
+You can list all commits that have taken place since a branch split off from
+another branch using `git log`. You just need to specify a ref range with
+the originating branch and the branch of interest.
+
+```bash
+$ git log master..my-feature-branch
+```
+
+That will list all commits on `my-feature-branch` since it branched off from
+`master`.
+
+I like to tighten up the output a bit with a flag:
+
+```bash
+$ git log master..my-feature-branch --oneline
+```
+
+See `man git-log` for more details.
