## Stashing
```bash
git stash
```
moves working directory to stash. Then you are safe to `git pull`.

## Seeing diff between current and stash
See [this stackoverflow question](https://stackoverflow.com/questions/7677736/git-diff-against-a-stash)
```bash
git stash show -p
``` 
or for a specific stash
```bash
git stash show -p stash@{1}
```

## Discarding stash
```bash
git stash drop
```
or
```bash
git stash drop stash@{1}
```
