# different between two dots and three

In git the range notation behave differently between `log` and `diff`

```
     A---B---C topic
     /
D---E---F---G master
```

## Git log

### two dots (..)

`git log topic..master` : in *master* but not in *topic* (G, F)

`git log master..topic` : in *topic* but not *master* (C, B, A)

### three dots (...)

`git log topic...master` : in *master* and in *topic* but \*\*not both \*\* (G, F, C, B, A)

`git log master...topic` : the same (G, F, C, B, A)

## Git diff

### two dots (..)

`git diff topic..master` : what **is** and what **not** in *master* compared to *topic* (D, E, -A, -B, -C, +F, +G)

`git diff master..topic` : what **is** and what **not** in *topic* compared to *master* (D, E, -F, -G, +A, +B, +C)

### three dots (...)

`git diff topic...master` : in *master* but **not in \_topic**\_\*\* \*\* (D, E, +F, +G)

`git diff master...topic` : in *topic* but **not in \_master**\_\*\* \*\* (D, E, +A, +B, +C)
