##  Reset modes example

Commit 3 times as following,

![](../assets/001.png)

![](../assets/002.png)


Then make changes and add to index. The diff results ...

`git diff` (Compare working tree to index)

No difference

`git diff --cached` (Compare index to HEAD)

![](../assets/003.png)

`git diff HEAD` (Compare working tree to HEAD)

![](../assets/004.png)


Now reset the the 1st commit and see the differences between 3 modes

* mixed

$ git reset –mixed af01615

![](../assets/005.png)

![](../assets/006.png)

ps. `git diff --cached` will get nothing.


* soft

$ git reset –soft af01615

![](../assets/007.png)

![](../assets/008.png)

ps. `git diff` will get nothing. 


* hard

$ git reset –hard af01615
`

ps. git diff, git diff --cached, git diff HEAD will all get nothing.
