```
Stash changes:

```
git stash apply

View commit history graphically:

git log --graph --oneline --decorate --all

Show the last commit:

git diff --staged
```
Show the difference between two branches:
```
git diff <branch1> <branch2>
```
Show the difference between two commits:
```
git diff <commit1> <commit2>
