`git log --graph`

For the strong.

git log --abbrev-commit --decorate --graph --pretty=oneline master HEAD

Output:

* b4ec057 (master) 5
* 0b37c1b 4
| * fbfbfe8 (HEAD -> my-feature) 7
| * 7b0f59d 6
|/
* 661cfab 3
* 6d748a9 2
* c5f8a2c 1

* b4ec057 (master) 5
| * fbfbfe8 (HEAD -> my-feature) 7
|/
* c5f8a2c 1

As we can see, this removes any commit that is neither:
